Definitions
- This invention relates to re-closable dispensing containers for flowable material, particularly non-liquids and semi-liquids such as tooth paste, creams, glue, condiments such as mayonnaise, catsup, and other materials of like consistency.
- the present invention relates to a novel cap structure useful with flowable material containers.
- This delayed delivery of container contents through the exit portal of the container provides a residue of contents proximate the exit portal which tends to dry over time with concomitant build up of an undesirable accumulation of container contents about the exit portal.
- Such accumulation of container contents not only is visually distasteful, it tends to be pushed from the exit portal by advancing container contents during a subsequent dispensing event. Due to the tenacity with which the dried accumulation adheres to the exit portal, excessive expulsion pressure often is needed to dislodge the dried accumulated contents. This action also often results in an even more undesired quantity of contents being expelled from the container during such subsequent use event by the user.
- the dried and hardened accumulated contents become an undesired part of such subsequently recovered container contents, even to the point of requiring disposal of such subsequently recovered contents and then repeating the dispensing and recovery action to acquire the desired quantity of “fresh” container contents.
- the common collapsible tubular container for tooth paste is one example of a prior container which exhibits this undesirable feature. In this instance, sanitation of the dispensed residual contents also may become a problem.
- the process invention comprises a novel exit portal for a container designed to dispense individual quantities of a flowable material, such as for example a paste material, from the container at selectable spaced apart times.
- a container which includes a conventional threaded tubular dispensing nozzle associated with, (commonly integral with), and projecting from one end of the container.
- a substantially conical inner cap having an internally threaded open base and of a first color is provided.
- the internal threads of the inner cap are adapted to be threadably mounted on the external threads of the neck portion of the nozzle such that the inner cap may be tightened on the nozzle to secure the inner cap in place during repeated events of dispensing of flowable material out of the container over the anticipated life of the container.
- the distal end of the nozzle opens into the interior of the inner cap to develop a passageway for flow of container contents from the container through the nozzle, and into the interior of the inner cap.
- the inner cap includes an aperture through the wall of the inner cap which provides for the outflow of container contents from the reservoir through the aperture.
- the inner cap has applied thereover an outer cap of a contrasting color to the color of the inner cap.
- the outer cap snugly fits over and covers the outer surface of the inner cap while providing for rotation of the outer cap relative to the inner cap without permitting material physical separation of these caps from one another.
- the outer cap is affixed to the inner cap by a rotationally slidable snap fit of the outer cap onto a peripheral groove defined on the exterior of the inner cap, thereby permitting rotation of the outer cap relative to the inner cap.
- the outer cap also includes an aperture through the wall of the outer cap, such aperture being of like or similar size and geometry as the aperture in the wall of the inner cap, so that when such aperture of the outer cap is in register with the aperture of the inner cap, outflow of the contents of the container along an exit passageway including the nozzle, the inner cap passageway, and the registered apertures of the inner and outer caps to the exterior of the outer cap may occur.
- Closure of the aperture through the inner cap is affected by rotating the outer cap such that the apertures of the caps are out of register.
- Control over dispensing of the contents of the container is therefore effected by rotation of the outer cap into and out of register with the aperture of the inner cap.
- the physical fit of the outer cap on the inner cap is selected to provide sliding physical engagement of the inner surface of the outer cap with the outer surface of the inner cap, thereby minimizing or fully eliminating any tendency of outflowing contents of the container from flowing between the contiguous surfaces of the inner and outer caps, and thereby precluding build up of container contents between the matching surfaces of the inner and outer caps at all times, irrespective of whether the apertures of the inner and outer caps are in register (open) or out of register (closed).
- the rotation of the outer cap is limited in one of the clockwise and counterclockwise directions by a stop lug affixed to one of the inner and outer caps and which rides within a curved slot defined in the other of the inner and outer caps. Positioning of such stop lug and slot is chosen such that when the outer cap is rotated a distance sufficient to move the aperture of the outer cap out of register with the aperture in the inner cap, one end of the slot engages the stop to halt further rotation of the outer cap in the same direction.
- the opposite end of the slot is located such that when the outer cap is rotated to bring the aperture of the outer cap into register with the aperture of the inner cap, this opposite end of the slot engages the stop lug to halt further rotation of the outer cap beyond such registration.
- a user may look into the aperture of the outer cap and note the appearance of the contrasting color of the inner cap, thereby indicating that the aperture of the inner cap is closed.
- the outer circumference of the perimetral flange of the outer cap is of a geometry providing an aid for grasping and rotation of the outer cap.
- the diametral dimension of cross section of the outer cap is chosen to provide for fitting of the dispensing end of the container snugly within an outer shipping container, thereby stabilizing the position of the container within such shipping container.

- a reclosable dispensing container cap for flowable material containers incorporating various features of the present invention is disclosed herein and illustrated generally in the Figures.
- the reclosable dispensing container cap, or “reclosable cap,” is designed to dispense individual quantities of a flowable material, such as for example a paste material, from the container at selectable spaced apart times employing application of internal pressure within the container and against the container contents.
- a collapsible tubular container 10 of the type known in the art suitable for receipt and dispending of a flowable material 14 , such as tooth paste or other flowable material, is provided with a nozzle 12 through which the contents of the container 16 may be dispensed.
- this nozzle includes a tubular neck portion 18 having a first end 20 which may be fixedly secured to a first end 22 of the tubular container, or, preferably, integrally formed with the container.
- the depicted nozzle 12 includes external threads 24 substantially along its length. The opposite second end 26 of the nozzle is open.
- a substantially conical inner cap 28 is provided defining a sloping inner wall 34 and an apex 36 .
- the inner cap 28 is internally threaded at its base 30 with threads 32 , which match the external threads on the neck portion 18 of the nozzle 12 . Accordingly, the base 30 of the inner cap 28 may be threaded onto the nozzle 12 to the extent that such inner cap 28 resists unintentional removal of the inner cap 28 from the nozzle 12 .
- This mounting of the inner cap 28 onto the nozzle 12 further brings the sloping inner wall 34 of the apex 36 of the inner cap 28 into sealing engagement with the distal second end 26 of the nozzle 12 thereby defining, with the nozzle 12 , a reservoir 38 for the receipt and storage of container contents within such reservoir.
- the tubular nozzle 12 defines an open passageway between the interior of the container and the reservoir.
- an aperture 42 through the wall of the inner cap 28 proximate the apex 36 which provides for flow communication between the interior of the container 10 , through the tubular portion of the nozzle 12 , through the aperture 42 of the inner cap 28 to an exterior of the inner cap 28 .
- collapse of the container 10 may force contents 16 of the container 10 through the nozzle 12 and the reservoir 38 into and through the aperture 42 of the inner cap 28 .
- the inner cap 28 is substantially surrounded and covered by an outer cap 44 which exhibits an inner surface 46 of a geometry which permits the inner surface 46 of the outer cap 44 to snugly, slidably fit in covering relationship to the outer surface 48 of the inner cap 28 without generating material physical separation of these contiguous surfaces of the two caps 28 , 44 .
- such outer cap 44 further includes a bottom peripheral flange 50 proximate the base 52 of the outer cap 44 which overlies and slidably engages a corresponding peripheral flange 54 on the inner cap 28 .
- a circumferential lip 56 provided on the inner surface 46 of the outer cap 44 proximate a junction 58 of the flange 50 with the base 52 of the outer cap 44 is snap fitted into a corresponding circumferential groove 62 in an outer surface 48 of the inner cap 28 , thereby ensuring continued snug engagement of the outer cap 44 on the inner cap 28 while simultaneously providing for rotation of the outer cap 44 relative to the inner cap 28 .
- the outer cap 44 is provided with an aperture 66 through its wall at an altitude 68 corresponding to that altitude 70 of the inner cap 28 along which the aperture 42 of the inner cap 28 is located.
- Rotation of the outer cap 44 relative to the inner cap 28 provides for selective location of the aperture 66 of the outer cap 44 along the corresponding altitudes 68 , 70 such that the apertures 42 , 66 may be aligned in register with one another, thereby completing the formation of an overall exit flow passageway 72 for container contents 16 from the interior of the container 10 to the exterior of the outer cap 44 where such contents may be recovered by a user.
- the degree of rotation of the outer cap 44 and its aperture 66 is bidirectionally limited.
- the peripheral flange 54 of the inner cap 28 is provided with an upstanding stop lug 74 in position to be slidably received within a slot 76 defined in the overlying flange 50 of the outer cap 44 .
- the length and location of a first end 78 of such slot 76 is selected to permit that degree of rotation of the outer cap 44 relative to the inner cap 28 which will locate the aperture 66 of the outer cap 44 out of register with the aperture 42 of the inner cap 28 , thereby closing off the aperture 42 of the inner cap 28 (see FIG. 3 ).
- This action effects closing of the exit passageway 72 for dispensing of the contents of the container by reason of the solid wall of the outer cap 44 moving into overlying relationship to the aperture 42 of the inner cap 28 .
- the location of the stop lug 74 and the second end 80 of the slot 76 in the flange 50 of the outer cap 44 may be chosen to halt rotation of the outer cap 44 when the aperture 66 of the outer cap 44 comes into register with the aperture 42 of the inner cap 42 , thereby opening up the exit passageway 72 and allowing outflow of contents 16 of the container 10 to the exterior of the outer cap 44 in position for recovery of dispensed container contents by a user of the container.
- the outer cap 44 may be rotated relative to the fixed inner cap 28 to relocate the aperture 66 of the outer cap 44 out of register with the aperture 42 of the inner cap 28 , thereby closing the exit passageway 72 .
- a visual indicator is provided to indicate whether the exit passageway 72 is open or closed.
- the inner cap 28 is colored a color 82 which contrasts the coloring of both the container contents 16 and the outer cap 44 .
- the aperture 66 of the outer cap 44 may be cleared of dispensed container contents to the extent that the user may look into the aperture 66 of the outer cap 44 and see the contrasting color 82 of the inner cap 28 , thereby providing a visual indication that the exit passageway 72 is closed.
- the outboard circumference 84 of the flange 50 of the outer cap 44 is of a geometry, (e.g., scalloped) which functions as an aid in grasping the outer cap 44 for rotation of the outer cap 44 in relation to the inner cap 28 when opening and closing the flow path 72 for dispensing of the contents of the container 10 via the registered apertures 42 , 66 of the inner and outer caps 28 , 44 .
- the outer cap 44 is sized to fit neatly within a standard shipping/storage outer container 86 of the container 10 such that the outer cap 44 is configured to aid in stabilizing the container 10 within the shipping/storage outer container 86 .
- the scalloped perimetral flange 50 of the outer cap 44 is maximized to enhance the ability of a user to grasp such scalloped flange 50 for retrieving the container 10 from a shipping or storage holder and subsequently grasping of the flange 50 of the outer cap 44 for rotation of such outer cap 44 in the course of aligning the apertures 42 , 66 of the inner and outer caps 28 , 44 for dispensing of the container contents 16 , and thereafter counter rotating the outer cap 44 to close the exit passageway 72 against further flowable materials from exiting the container 10 .
- This maximized size feature of the present embodiment is especially useful where the user suffers from loss of grasping strength due to stroke, Parkison's Disease, tremors, or other like ailments.
- the present enlarged scalloped flange 50 on the outer cap 44 eliminates the frustrations associated with prior art small caps such as dropping the cap onto the floor or into a sink drain. This latter advantage is enhanced by reason of the snap fit of the outer cap 44 onto the inner cap 28 whereby the rotation of the outer cap 44 relative to the inner cap 28 when opening and closing the exit passageway 72 for the contents of the container 10 is easily accomplished and without concern for inadvertent removal of the outer cap 44 from the inner cap 28 .
- FIGS. 5 through 9 illustrate another embodiment of the present invention.
- a substantially elongated inner cap 28 a is provided having a substantially hollow spherical upper portion 88 in fluid communication with an elongated tubular central portion 90 and a tubular lower portion 92 .
- the lower portion 92 of the inner cap 28 a is provided with internal threading 32 which matches the external threads 24 on the nozzle 12 of the container 10 , and a bottom peripheral flange 54 is provided at a lower end 94 of the inner cap lower portion 92 .
- the aperture 42 of the inner cap 28 a is provided through the wall of the spherical upper portion 88 of the inner cap 28 a and provides for flow communication between the nozzle 12 of the container 10 , through the tubular central and lower portions 90 , 92 of the of the inner cap 28 a , through the spherical upper portion 88 of the inner cap 28 a , to an exterior of the inner cap 28 .
- the inner cap 28 a is surrounded and covered by a substantially conical outer cap 44 a .
- An apex portion 96 of the outer cap 44 a defines an inner spherical surface 98 having a geometry which permits the inner spherical surface 98 of the outer cap 44 a to snugly, slidably fit in covering relationship to the spherical upper portion 88 of the inner cap 28 a without generating material physical separation of these contiguous surfaces of the two caps 28 a , 44 a .
- the apex portion 96 of the outer cap 44 a further defines an aperture 66 through its wall at an altitude corresponding to that altitude of the inner cap 28 a along which the aperture 42 of the inner cap 28 a is located, such that rotation of the outer cap 44 a relative to the inner cap 28 a provides for selective location of the aperture 66 of the outer cap 44 a in registration with the aperture 42 of the inner cap 28 a , thereby completing the formation of an overall exit flow passageway 72 for container contents 16 from the interior of the container 10 to the exterior of the outer cap 44 a.
- a lower boundary of the inner spherical surface 98 of the outer cap 44 a terminates to define a circumferential inner lip 56 a to allow the outer cap 44 a to be snap fitted into a corresponding circumferential groove 62 a defined by the intersection between the upper portion 88 and central portion 90 of the inner cap 28 a , thereby ensuring continued snug engagement of the outer cap 44 a on the inner cap 28 a while simultaneously providing for rotation of the outer cap 44 a relative to the inner cap 28 a .
- a lower peripheral edge 100 of the outer cap 44 a extends downwardly and outwardly to the outer perimeter 102 of the peripheral flange 54 of the inner cap 28 a , such that the outer cap 44 a overlies and slidably engages the peripheral flange 54 of the inner cap 28 a.
- the inner cap 28 a is provided with a central flange 104 surrounding an intersection between the central portion 90 and the lower portion 92 of the inner cap 28 a .
- the central flange 104 defines a channel 76 a which is adapted to slidably receive and engage an internally protruding stop lug 74 a defined along an interior surface 46 a of the outer cap 44 a .
- the length and location of a first end 78 a of such slot 76 a is selected to permit that degree of rotation of the outer cap 44 a relative to the inner cap 28 a which will locate the aperture 66 of the outer cap 44 a out of register with the aperture 42 of the inner cap 28 a , thereby closing off the aperture 42 of the inner cap 28 a .
- a second end 80 a of such slot 76 a is selected to permit rotation of the outer cap 44 a relative to the inner cap 28 a to locate the aperture 66 of the outer cap 44 a in registration with the aperture 42 of the inner cap 28 a , thereby opening the aperture 42 of the inner cap 28 a and completing the formation of an overall exit flow passageway 72 for container contents 16 from the interior of the container 10 to the exterior of the outer cap 44 a .
- a slight constriction 106 of the slot 76 a is defined at a distance from each of the first and second ends 78 a , 80 a , of the slot 76 a approximately equal to the overall width of the stop lug 74 a .
- Each of the constrictions 106 of the slot 76 a provides at least some measure of frictional resistance to sliding of the stop lug 74 a along the slot 76 a beyond the constriction 106 , yet does not completely prevent sliding of the stop lug 74 a along the slot 76 a beyond the constriction 106 .
- rotation of the outer cap 44 a relative to the inner cap 28 a sufficient to slide the stop lug 74 a beyond one of the constrictions 106 and to locate the stop lug 74 a at the corresponding end 78 a , 80 a of the slot 76 a results in engagement of the stop lug 74 a by the corresponding constriction 106 to frictionally secure the stop lug 74 a at the corresponding end 78 a , 80 a of the slot 76 a , thereby releasably securing the outer cap 44 a in its position relative to the inner cap 28 a at the respective limit of rotation provided by the slot 76 a and stop lug 74 a.
- the portion of the wall forming the apex 96 of the outer cap 44 a and specifically the portion of the wall of the outer cap 44 a surrounding the aperture 66 of the outer cap 44 a is of a relatively thin width as compared to the remainder of the outer cap 44 a .
- Such thin width of the wall of the outer cap 44 a surrounding the aperture 66 serves to reduce the overall volume of the aperture 66 .
- any container contents 16 retained within the aperture 66 may be cleared therefrom to the extent that the user may look into the aperture 66 of the outer cap 44 a and see the contrasting color 82 of the inner cap 28 a , thereby providing a visual indication that the exit passageway 72 is closed
- the outer surface 108 of the outer cap 44 a defines a plurality of indentations 110 which allow the outer cap 44 a to define a geometry, (e.g., scalloped) which functions as an aid in grasping the outer cap 44 a for rotation of the outer cap 44 a in relation to the inner cap 28 a when opening and closing the flow path 72 for dispensing of the contents of the container 10 via the registered apertures 42 , 66 of the inner and outer caps 28 a , 44 a .
- a geometry e.g., scalloped
- the inner and outer caps 28 a , 44 a are sized to span a width dimension of the container 10 such that the combination of the inner and outer caps 28 a , 44 a blend to the natural size, shape, and contour of the container 10 .
- the inner and outer caps 28 a , 44 a can be sized to conform to other dimensional requirements without departing from the spirit and scope of the present invention.
- the reclosable dispensing container cap for flowable material may be combined with a container to produce a reclosable dispensing container for flowable material without departing from the spirit and scope of the present invention.
- the inner cap 28 b is integrally formed with the container 10 a .
- An outer cap 44 b is provided which is adapted to substantially cover and surround the inner cap 28 b .
- a lower peripheral edge 100 of the outer cap 44 b extends downwardly and outwardly toward the container 10 a , such that the outer cap 44 a overlies and slidably engages a portion of the container 10 a proximate the inner cap 28 b .
- the inner cap 28 b is non-removable from the container 10 a , such that upon emptying the contents 16 of the container 10 a , the inner and outer caps 28 b , 44 b may be discarded with the empty container 10 a.
- reclosable dispensing container cap for flowable material provides a clean and reliable means of opening and sealing a flowable material container for dispensing of flowable contents within the container.

Abstract
A reclosable dispensing container cap for dispensing flowable material from a container is disclosed. An inner cap is provided which defines a passageway adapted to be placed in fluid communication with a container nozzle. The inner cap defines a first aperture in fluid communication between the passageway and an exterior of the inner cap. An outer cap is provided to surround the inner cap such that the outer cap is slidably rotatable in relation to the inner cap between at least a first position and a second position. The outer cap defines a second aperture disposed along the outer cap such that the second aperture is in substantial registration with the first aperture when the outer cap is rotated to the first position and out of registration with the first aperture when the outer cap is rotated to the second position.

- This invention relates to re-closable dispensing containers for flowable material, particularly non-liquids and semi-liquids such as tooth paste, creams, glue, condiments such as mayonnaise, catsup, and other materials of like consistency. In particular, the present invention relates to a novel cap structure useful with flowable material containers.
- When dispensing flowable material, such as tooth paste, for example from a collapsible container, the collapse of the container builds up pressure within the container which forces contents of the container out of the container through some form of exit portal in the container and positions the expelled contents for recovery of the contents by a user. When this mode of dispensing the contents from the container involves a non-liquid or semi-liquid flowable material, as opposed to a liquid material, cessation of pressure applied to collapse the container commonly results in delayed or continued expulsion of such contents after the user has released application of pressure applied for collapsing the container and has recovered the desired quantity of the container contents. This delayed delivery of container contents through the exit portal of the container provides a residue of contents proximate the exit portal which tends to dry over time with concomitant build up of an undesirable accumulation of container contents about the exit portal. Such accumulation of container contents not only is visually distasteful, it tends to be pushed from the exit portal by advancing container contents during a subsequent dispensing event. Due to the tenacity with which the dried accumulation adheres to the exit portal, excessive expulsion pressure often is needed to dislodge the dried accumulated contents. This action also often results in an even more undesired quantity of contents being expelled from the container during such subsequent use event by the user. In addition to this wasteful dispensing of the unwanted or unneeded container contents, the dried and hardened accumulated contents become an undesired part of such subsequently recovered container contents, even to the point of requiring disposal of such subsequently recovered contents and then repeating the dispensing and recovery action to acquire the desired quantity of “fresh” container contents. The common collapsible tubular container for tooth paste is one example of a prior container which exhibits this undesirable feature. In this instance, sanitation of the dispensed residual contents also may become a problem.
- In one embodiment, the process invention comprises a novel exit portal for a container designed to dispense individual quantities of a flowable material, such as for example a paste material, from the container at selectable spaced apart times. One embodiment of the present invention is adapted to be used with a container which includes a conventional threaded tubular dispensing nozzle associated with, (commonly integral with), and projecting from one end of the container. In one embodiment of the present invention, a substantially conical inner cap having an internally threaded open base and of a first color is provided. The internal threads of the inner cap are adapted to be threadably mounted on the external threads of the neck portion of the nozzle such that the inner cap may be tightened on the nozzle to secure the inner cap in place during repeated events of dispensing of flowable material out of the container over the anticipated life of the container. When so threaded on the nozzle neck, the distal end of the nozzle opens into the interior of the inner cap to develop a passageway for flow of container contents from the container through the nozzle, and into the interior of the inner cap. Further, the inner cap includes an aperture through the wall of the inner cap which provides for the outflow of container contents from the reservoir through the aperture.
- The inner cap has applied thereover an outer cap of a contrasting color to the color of the inner cap. The outer cap snugly fits over and covers the outer surface of the inner cap while providing for rotation of the outer cap relative to the inner cap without permitting material physical separation of these caps from one another. In one embodiment, the outer cap is affixed to the inner cap by a rotationally slidable snap fit of the outer cap onto a peripheral groove defined on the exterior of the inner cap, thereby permitting rotation of the outer cap relative to the inner cap.
- The presence of the outer cap in covering relationship to the inner cap functions to establish opening and closure of the aperture through the inner cap. To this end, the outer cap also includes an aperture through the wall of the outer cap, such aperture being of like or similar size and geometry as the aperture in the wall of the inner cap, so that when such aperture of the outer cap is in register with the aperture of the inner cap, outflow of the contents of the container along an exit passageway including the nozzle, the inner cap passageway, and the registered apertures of the inner and outer caps to the exterior of the outer cap may occur. Closure of the aperture through the inner cap is affected by rotating the outer cap such that the apertures of the caps are out of register. Control over dispensing of the contents of the container is therefore effected by rotation of the outer cap into and out of register with the aperture of the inner cap. In one embodiment, the physical fit of the outer cap on the inner cap is selected to provide sliding physical engagement of the inner surface of the outer cap with the outer surface of the inner cap, thereby minimizing or fully eliminating any tendency of outflowing contents of the container from flowing between the contiguous surfaces of the inner and outer caps, and thereby precluding build up of container contents between the matching surfaces of the inner and outer caps at all times, irrespective of whether the apertures of the inner and outer caps are in register (open) or out of register (closed).
- In certain embodiments, the rotation of the outer cap is limited in one of the clockwise and counterclockwise directions by a stop lug affixed to one of the inner and outer caps and which rides within a curved slot defined in the other of the inner and outer caps. Positioning of such stop lug and slot is chosen such that when the outer cap is rotated a distance sufficient to move the aperture of the outer cap out of register with the aperture in the inner cap, one end of the slot engages the stop to halt further rotation of the outer cap in the same direction. In similar manner, the opposite end of the slot is located such that when the outer cap is rotated to bring the aperture of the outer cap into register with the aperture of the inner cap, this opposite end of the slot engages the stop lug to halt further rotation of the outer cap beyond such registration. In certain embodiments, a user may look into the aperture of the outer cap and note the appearance of the contrasting color of the inner cap, thereby indicating that the aperture of the inner cap is closed.
- In certain embodiments, the outer circumference of the perimetral flange of the outer cap is of a geometry providing an aid for grasping and rotation of the outer cap. In one embodiment, the diametral dimension of cross section of the outer cap is chosen to provide for fitting of the dispensing end of the container snugly within an outer shipping container, thereby stabilizing the position of the container within such shipping container.

FIG. 10 is a cross-sectional exploded view of another embodiment of a reclosable dispensing container cap for flowable material containers of the present invention, depicting the inner cap integrally formed with a container for a flowable material. - A reclosable dispensing container cap for flowable material containers incorporating various features of the present invention is disclosed herein and illustrated generally in the Figures. The reclosable dispensing container cap, or “reclosable cap,” is designed to dispense individual quantities of a flowable material, such as for example a paste material, from the container at selectable spaced apart times employing application of internal pressure within the container and against the container contents.
- With initial reference to
FIG. 1 , in the depicted embodiment of the present invention, a collapsibletubular container 10 of the type known in the art suitable for receipt and dispending of aflowable material 14, such as tooth paste or other flowable material, is provided with anozzle 12 through which the contents of thecontainer 16 may be dispensed. In the depicted embodiment, this nozzle includes atubular neck portion 18 having afirst end 20 which may be fixedly secured to afirst end 22 of the tubular container, or, preferably, integrally formed with the container. The depictednozzle 12 includesexternal threads 24 substantially along its length. The oppositesecond end 26 of the nozzle is open. - Referring to
FIGS. 1 and 2 , a substantially conicalinner cap 28 is provided defining a slopinginner wall 34 and anapex 36. Theinner cap 28 is internally threaded at itsbase 30 withthreads 32, which match the external threads on theneck portion 18 of thenozzle 12. Accordingly, thebase 30 of theinner cap 28 may be threaded onto thenozzle 12 to the extent that suchinner cap 28 resists unintentional removal of theinner cap 28 from thenozzle 12. This mounting of theinner cap 28 onto thenozzle 12 further brings the slopinginner wall 34 of theapex 36 of theinner cap 28 into sealing engagement with the distalsecond end 26 of thenozzle 12 thereby defining, with thenozzle 12, areservoir 38 for the receipt and storage of container contents within such reservoir. When theinner cap 28 is so mounted, thetubular nozzle 12 defines an open passageway between the interior of the container and the reservoir. - In the several Figures there is depicted an
aperture 42 through the wall of theinner cap 28 proximate theapex 36 which provides for flow communication between the interior of thecontainer 10, through the tubular portion of thenozzle 12, through theaperture 42 of theinner cap 28 to an exterior of theinner cap 28. Thus, when theaperture 42 of theinner cap 28 is uncovered, collapse of thecontainer 10 may forcecontents 16 of thecontainer 10 through thenozzle 12 and thereservoir 38 into and through theaperture 42 of theinner cap 28. - In accordance with one aspect of the present invention, the
inner cap 28 is substantially surrounded and covered by anouter cap 44 which exhibits aninner surface 46 of a geometry which permits theinner surface 46 of theouter cap 44 to snugly, slidably fit in covering relationship to theouter surface 48 of theinner cap 28 without generating material physical separation of these contiguous surfaces of the two 28, 44. In the depicted embodiment, suchcaps outer cap 44 further includes a bottomperipheral flange 50 proximate thebase 52 of theouter cap 44 which overlies and slidably engages a correspondingperipheral flange 54 on theinner cap 28. - A
circumferential lip 56 provided on theinner surface 46 of theouter cap 44 proximate ajunction 58 of theflange 50 with thebase 52 of theouter cap 44 is snap fitted into a correspondingcircumferential groove 62 in anouter surface 48 of theinner cap 28, thereby ensuring continued snug engagement of theouter cap 44 on theinner cap 28 while simultaneously providing for rotation of theouter cap 44 relative to theinner cap 28. - As depicted in
FIG. 1 , theouter cap 44 is provided with anaperture 66 through its wall at analtitude 68 corresponding to thataltitude 70 of theinner cap 28 along which theaperture 42 of theinner cap 28 is located. Rotation of theouter cap 44 relative to theinner cap 28 provides for selective location of theaperture 66 of theouter cap 44 along the corresponding 68, 70 such that thealtitudes 42, 66 may be aligned in register with one another, thereby completing the formation of an overallapertures exit flow passageway 72 forcontainer contents 16 from the interior of thecontainer 10 to the exterior of theouter cap 44 where such contents may be recovered by a user. - In the illustrated embodiment, the degree of rotation of the
outer cap 44 and itsaperture 66 is bidirectionally limited. In the depicted embodiment, theperipheral flange 54 of theinner cap 28 is provided with anupstanding stop lug 74 in position to be slidably received within aslot 76 defined in the overlyingflange 50 of theouter cap 44. As seen inFIGS. 3 and 4 , the length and location of afirst end 78 ofsuch slot 76 is selected to permit that degree of rotation of theouter cap 44 relative to theinner cap 28 which will locate theaperture 66 of theouter cap 44 out of register with theaperture 42 of theinner cap 28, thereby closing off theaperture 42 of the inner cap 28 (seeFIG. 3 ). This action effects closing of theexit passageway 72 for dispensing of the contents of the container by reason of the solid wall of theouter cap 44 moving into overlying relationship to theaperture 42 of theinner cap 28. - Referring to
FIG. 4 , rotation of theouter cap 44 in a direction such as to move thestop lug 74 away from the slotfirst end 78 is stopped when the oppositesecond end 80 of theslot 76 engages thestop lug 74 of theinner cap flange 54. Thus, the location of thestop lug 74 and thesecond end 80 of theslot 76 in theflange 50 of theouter cap 44 may be chosen to halt rotation of theouter cap 44 when theaperture 66 of theouter cap 44 comes into register with theaperture 42 of theinner cap 42, thereby opening up theexit passageway 72 and allowing outflow ofcontents 16 of thecontainer 10 to the exterior of theouter cap 44 in position for recovery of dispensed container contents by a user of the container. - When the dispensed contents of the
container 10 are recovered by a user, theouter cap 44 may be rotated relative to the fixedinner cap 28 to relocate theaperture 66 of theouter cap 44 out of register with theaperture 42 of theinner cap 28, thereby closing theexit passageway 72. In several embodiments, a visual indicator is provided to indicate whether theexit passageway 72 is open or closed. For example, in the illustrated embodiment, theinner cap 28 is colored acolor 82 which contrasts the coloring of both thecontainer contents 16 and theouter cap 44. In this embodiment, upon movement of theaperture 66 of theouter cap 44 out of register with theaperture 42 of theinner cap 28, theaperture 66 of theouter cap 44 may be cleared of dispensed container contents to the extent that the user may look into theaperture 66 of theouter cap 44 and see thecontrasting color 82 of theinner cap 28, thereby providing a visual indication that theexit passageway 72 is closed. - Referring to
FIGS. 2 through 4 , theoutboard circumference 84 of theflange 50 of theouter cap 44 is of a geometry, (e.g., scalloped) which functions as an aid in grasping theouter cap 44 for rotation of theouter cap 44 in relation to theinner cap 28 when opening and closing theflow path 72 for dispensing of the contents of thecontainer 10 via the registered 42, 66 of the inner andapertures 28, 44. Referring toouter caps FIG. 2 , in the illustrated embodiment, theouter cap 44 is sized to fit neatly within a standard shipping/storageouter container 86 of thecontainer 10 such that theouter cap 44 is configured to aid in stabilizing thecontainer 10 within the shipping/storageouter container 86. - In one embodiment, the
scalloped perimetral flange 50 of theouter cap 44 is maximized to enhance the ability of a user to grasp suchscalloped flange 50 for retrieving thecontainer 10 from a shipping or storage holder and subsequently grasping of theflange 50 of theouter cap 44 for rotation of suchouter cap 44 in the course of aligning the 42, 66 of the inner andapertures 28, 44 for dispensing of theouter caps container contents 16, and thereafter counter rotating theouter cap 44 to close theexit passageway 72 against further flowable materials from exiting thecontainer 10. This maximized size feature of the present embodiment is especially useful where the user suffers from loss of grasping strength due to stroke, Parkison's Disease, tremors, or other like ailments. Still further, the present enlarged scallopedflange 50 on theouter cap 44 eliminates the frustrations associated with prior art small caps such as dropping the cap onto the floor or into a sink drain. This latter advantage is enhanced by reason of the snap fit of theouter cap 44 onto theinner cap 28 whereby the rotation of theouter cap 44 relative to theinner cap 28 when opening and closing theexit passageway 72 for the contents of thecontainer 10 is easily accomplished and without concern for inadvertent removal of theouter cap 44 from theinner cap 28. -
FIGS. 5 through 9 illustrate another embodiment of the present invention. As shown inFIGS. 5 and 6 , in one embodiment a substantially elongatedinner cap 28 a is provided having a substantially hollow sphericalupper portion 88 in fluid communication with an elongated tubularcentral portion 90 and a tubularlower portion 92. Thelower portion 92 of theinner cap 28 a is provided with internal threading 32 which matches theexternal threads 24 on thenozzle 12 of thecontainer 10, and a bottomperipheral flange 54 is provided at alower end 94 of the inner caplower portion 92. Theaperture 42 of theinner cap 28 a is provided through the wall of the sphericalupper portion 88 of theinner cap 28 a and provides for flow communication between thenozzle 12 of thecontainer 10, through the tubular central and 90, 92 of the of thelower portions inner cap 28 a, through the sphericalupper portion 88 of theinner cap 28 a, to an exterior of theinner cap 28. - In the illustrated embodiment, the
inner cap 28 a is surrounded and covered by a substantially conicalouter cap 44 a. Anapex portion 96 of theouter cap 44 a defines an innerspherical surface 98 having a geometry which permits the innerspherical surface 98 of theouter cap 44 a to snugly, slidably fit in covering relationship to the sphericalupper portion 88 of theinner cap 28 a without generating material physical separation of these contiguous surfaces of the two 28 a, 44 a. Thecaps apex portion 96 of theouter cap 44 a further defines anaperture 66 through its wall at an altitude corresponding to that altitude of theinner cap 28 a along which theaperture 42 of theinner cap 28 a is located, such that rotation of theouter cap 44 a relative to theinner cap 28 a provides for selective location of theaperture 66 of theouter cap 44 a in registration with theaperture 42 of theinner cap 28 a, thereby completing the formation of an overallexit flow passageway 72 forcontainer contents 16 from the interior of thecontainer 10 to the exterior of theouter cap 44 a. - A lower boundary of the inner
spherical surface 98 of theouter cap 44 a terminates to define a circumferentialinner lip 56 a to allow theouter cap 44 a to be snap fitted into a correspondingcircumferential groove 62 a defined by the intersection between theupper portion 88 andcentral portion 90 of theinner cap 28 a, thereby ensuring continued snug engagement of theouter cap 44 a on theinner cap 28 a while simultaneously providing for rotation of theouter cap 44 a relative to theinner cap 28 a. In the depicted embodiment, a lowerperipheral edge 100 of theouter cap 44 a extends downwardly and outwardly to theouter perimeter 102 of theperipheral flange 54 of theinner cap 28 a, such that theouter cap 44 a overlies and slidably engages theperipheral flange 54 of theinner cap 28 a. - In the depicted embodiment, the
inner cap 28 a is provided with acentral flange 104 surrounding an intersection between thecentral portion 90 and thelower portion 92 of theinner cap 28 a. Thecentral flange 104 defines achannel 76 a which is adapted to slidably receive and engage an internally protrudingstop lug 74 a defined along an interior surface 46 a of theouter cap 44 a. As seen inFIGS. 7 and 8 , the length and location of afirst end 78 a ofsuch slot 76 a is selected to permit that degree of rotation of theouter cap 44 a relative to theinner cap 28 a which will locate theaperture 66 of theouter cap 44 a out of register with theaperture 42 of theinner cap 28 a, thereby closing off theaperture 42 of theinner cap 28 a. Conversely, the location of asecond end 80 a ofsuch slot 76 a is selected to permit rotation of theouter cap 44 a relative to theinner cap 28 a to locate theaperture 66 of theouter cap 44 a in registration with theaperture 42 of theinner cap 28 a, thereby opening theaperture 42 of theinner cap 28 a and completing the formation of an overallexit flow passageway 72 forcontainer contents 16 from the interior of thecontainer 10 to the exterior of theouter cap 44 a. In the illustrated embodiment, aslight constriction 106 of theslot 76 a is defined at a distance from each of the first and second ends 78 a, 80 a, of theslot 76 a approximately equal to the overall width of thestop lug 74 a. Each of theconstrictions 106 of theslot 76 a provides at least some measure of frictional resistance to sliding of thestop lug 74 a along theslot 76 a beyond theconstriction 106, yet does not completely prevent sliding of thestop lug 74 a along theslot 76 a beyond theconstriction 106. Thus, in this embodiment, rotation of theouter cap 44 a relative to theinner cap 28 a sufficient to slide thestop lug 74 a beyond one of theconstrictions 106 and to locate thestop lug 74 a at the 78 a, 80 a of thecorresponding end slot 76 a results in engagement of thestop lug 74 a by thecorresponding constriction 106 to frictionally secure thestop lug 74 a at the 78 a, 80 a of thecorresponding end slot 76 a, thereby releasably securing theouter cap 44 a in its position relative to theinner cap 28 a at the respective limit of rotation provided by theslot 76 a and stoplug 74 a. - Referring again to
FIGS. 5 and 6 , in the illustrated embodiment, the portion of the wall forming the apex 96 of theouter cap 44 a, and specifically the portion of the wall of theouter cap 44 a surrounding theaperture 66 of theouter cap 44 a is of a relatively thin width as compared to the remainder of theouter cap 44 a. Such thin width of the wall of theouter cap 44 a surrounding theaperture 66 serves to reduce the overall volume of theaperture 66. Thus, in this embodiment, after dispensing ofcontents 16 from within thecontainer 10 to an exterior of theouter cap 44 a, and upon movement of theaperture 66 of theouter cap 44 a out of register with theaperture 42 of theinner cap 28 a, retention ofcontainer contents 16 within theaperture 66 of theouter cap 44 a external to theinner cap 28 a is minimized. Referring toFIG. 9 , as discussed above, anycontainer contents 16 retained within theaperture 66 may be cleared therefrom to the extent that the user may look into theaperture 66 of theouter cap 44 a and see thecontrasting color 82 of theinner cap 28 a, thereby providing a visual indication that theexit passageway 72 is closed - Referring to
FIG. 9 , theouter surface 108 of theouter cap 44 a defines a plurality ofindentations 110 which allow theouter cap 44 a to define a geometry, (e.g., scalloped) which functions as an aid in grasping theouter cap 44 a for rotation of theouter cap 44 a in relation to theinner cap 28 a when opening and closing theflow path 72 for dispensing of the contents of thecontainer 10 via the registered 42, 66 of the inner andapertures 28 a, 44 a. Referring toouter caps FIG. 6 , the inner and 28 a, 44 a are sized to span a width dimension of theouter caps container 10 such that the combination of the inner and 28 a, 44 a blend to the natural size, shape, and contour of theouter caps container 10. Of course, those skilled in the art will recognize that the inner and 28 a, 44 a can be sized to conform to other dimensional requirements without departing from the spirit and scope of the present invention.outer caps - It will be understood that the reclosable dispensing container cap for flowable material may be combined with a container to produce a reclosable dispensing container for flowable material without departing from the spirit and scope of the present invention. For example, in the embodiment of
FIG. 10 , theinner cap 28 b is integrally formed with thecontainer 10 a. Anouter cap 44 b is provided which is adapted to substantially cover and surround theinner cap 28 b. A lowerperipheral edge 100 of theouter cap 44 b extends downwardly and outwardly toward thecontainer 10 a, such that theouter cap 44 a overlies and slidably engages a portion of thecontainer 10 a proximate theinner cap 28 b. In this embodiment, theinner cap 28 b is non-removable from thecontainer 10 a, such that upon emptying thecontents 16 of thecontainer 10 a, the inner and 28 b, 44 b may be discarded with theouter caps empty container 10 a. - From the foregoing description, it will be understood by one of skillin the art that a reclosable dispensing container cap for flowable material is disclosed. The reclosable dispensing container cap for flowable material provides a clean and reliable means of opening and sealing a flowable material container for dispensing of flowable contents within the container. While the present invention has been illustrated by description of several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and methods, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of applicant's general inventive concept.

14. The reclosable dispensing container cap of claim 13 , said outer cap lower portion defining a contoured surface for assisting in gripping said outer cap to rotate said outer cap in relation to said inner cap.
15. The reclosable dispensing container cap of claim 12 , wherein rotation of said outer cap relative to said inner cap is limited between said first and second positions.
16. The reclosable dispensing container cap of claim 12 further including a slot defined by one of said inner and outer caps and a stop lug defined by the other of said inner and outer caps, said stop lug being slidably received within and engaged by said slot to limit rotation of said outer cap relative to said inner cap between said first and second positions.
17. The reclosable dispensing container cap of claim 16 , said inner cap defining a second peripheral flange proximate an intersection of said inner cap central and lower portions, said second peripheral flange defining said slot.
18. The reclosable dispensing container cap of claim 12 further including an indicator for indicating whether said first aperture is closed off by said outer cap.
19. The reclosable dispensing container cap of claim 18 , wherein an outer surface of said inner cap proximate said first aperture is of a color in contrast to a color of said outer cap, whereby inspection of said second aperture to determine whether said inner cap color is visible through said second aperture provides indication of whether said first aperture is closed off by said outer cap.
20. The reclosable dispensing container cap of claim 12 , wherein said upper portion of said outer cap surrounding said second aperture is of a width less than the width of the remainder of said outer cap.
