Description

The present invention relates to closures for dispensing containers and in particular to closures for hoses. More specifically, the present invention relates to a closure that cooperates with a dispensing nozzle on a container that delivers a product. The invention also relates to a closure having a product outlet that is offset from the centerline of the hose and nozzle of the closure.

Conventional containers such as squeeze hoses generally preferably have a snap-hinge closure to allow the user to easily open or close the container, in such a way that the cap closing the container does not separate from the container after each use. When the lid is separated from the container, it is often easy to misplace the lid. Thus, the cap preferably remains attached to the container when product is dispensed from the hose. This form of closure is sometimes referred to as a "tie-on" closure.

Dispensing containers and closures are often used for viscous materials such as toothpaste. Toothpaste ingredients often present unique problems not found in other materials. One is the problem of storage, the material from which the container is made must include a suitable barrier to prevent the absorption of flavoring ingredients and oils. Since the closure remains in contact with the toothpaste for extended periods of time, it is important to reduce the area of the closure that is in contact with the toothpaste.

The type of cover that users typically prefer is attached to a base by quick hinges. Such closures typically include a hinge and the closure is biased in an open position during dispensing and in a closed position at other times. Although biased in a closed position when not dispensing product, the cap is snapped onto the base with manual force to fully close the hose and seal the outlet.

Hose closures with snap action hinges have been used in the art for several years. One of the earliest such closures is described in U.S. Patent No. 1,928,445, which discloses a rubber hinge connecting the lid to the base portion. The base is a threaded ring that fits over the threaded dispensing outlet of the hose. The lid is hinged to the base and is movable from a closed position sealing the tube outlet to a fully open position. The closure has a rubber membrane hinge connected to the base and lid to bias the lid in an open or closed position.

Another hose cap is disclosed in U.S. Patent No. 3,933,271. The cover has a base portion mounted on the hose and a cover portion connected to the base by snap hinges. When the lid is opened to a point less than the neutral position, the lid is biased closed. When the lid is opened beyond the neutral position, the lid will be biased open. This hinge structure provides this unique action of the lid.

U.S. Patent No. 4,403,712 discloses another membrane hinge for closures. Such closures are characterized in that the lid is either biased open or biased closed. An additional feature of this lid is that the membrane hinge is within the contour of the lid when the lid is in the closed position. U.S. Patent No. 4,503,991 discloses a different closure with snap hinges. This is a snap-action double hinge that connects the lid to the base. The portion of the closure that seals the dispensing opening of the container has a protrusion that fits downwardly into the dispensing opening. This quick action hinged closure has additional versatility due to the use of double hinges.

Another example of a snap hinge is disclosed in U.S. Patent No. 44,615,462. This hinge has a main section and two secondary sections, the primary section acts to stabilize the lid while the secondary sections provide snap action. This is not a membrane hinge, the hinge parts are not within the contour of the lid when in the closed position. U.S. Patent No. 4,854,473 discloses a related closure, the hinge of which is also a three-piece construction, in which closure the hinge of the closure will be within the contour of the bottom closure when the closure is in the closed position.

The above patents reflect the state of the art for hose snap action hinge closures, however, the above patents do not teach a closure suitable for use with hoses having nozzles, nor do they teach a closure with an off-center hose output. The product outlet closure, in addition, does not propose a snap-action hinged cover large enough for the hose to stand on the cover, and the surface of the cover's dispensing member is sloped to facilitate product delivery. The latter feature is important for toothpastes, which are delivered to toothbrushes. The sloped surface of the dispensing member facilitates delivery of the toothpaste to the toothbrush. Another advantage is that the cap can be used as a snap-on cap or as a removable cap, which will please more users.

The present invention relates to a closure adapted to receive the nozzle of a container such as a squeeze hose. The closure includes a bottom cover and a top cover hingedly connected to the bottom cover by snap hinges. In a preferred embodiment, the bottom cap has internal threads for cooperating with threads on the hose for mounting the bottom cap on the hose, and the bottom cap has a central opening forming an axial passage for material in the hose. In another preferred embodiment, the bottom cap is provided with annular ribs which cooperate with corresponding annular grooves in the nozzle for mounting the bottom cap on the hose.

In one embodiment of the invention, the nozzle of the container extends axially through the bottom cap and protrudes beyond the upper surface of the bottom cap. The lip of the center hole of the bottom cap engages in the annular groove on the nozzle. The cap includes an axial collar extending inwardly to engage the end of the nozzle and seal the nozzle when the cap is in the closed position.

In another alternative embodiment, the closure includes a dispensing nozzle and the container includes an outlet that seals against the inner face of the cap.

In another embodiment, the bottom cover includes an annular inner wall defining a central outlet passage, a horizontal tube extending from the annular inner wall to an axial discharge nozzle offset from the central axis of the bottom cover. The annular inner wall includes a lip capable of engaging the groove on the nozzle.

The present invention provides an effective and simple closure for a container dispensing outlet which overcomes the disadvantages and limitations of prior art closures. In a preferred embodiment of the present invention, the closure is used with a dispensing container which may be a tube, squeeze tube, flexible squeeze bottle or other pump or valve mechanism of any kind. container. Such containers preferably have an externally threaded dispensing outlet or spout for attachment of a closure.

In particular, the present invention relates to a closure for a squeeze container, such as hose 10, having a bottom cap 32 and a top cap 34.

As shown in FIG. 1, the hose 10 has a side wall 12 forming a body. The overall shape of the hose is like an ordinary squeeze hose, which flattens as the contents of the hose are squeezed out. The hose is substantially circular in cross-section and its bottom is sealed by a straight seam 14. The hose is generally made of a flexible plastic film material, although other materials such as thin metal sheets can also be used. When the hose is made of plastic, the bottom seam 14 is formed by welding.

The container and closure assembly of the present invention is particularly suitable for dispensing toothpaste, jelly-like materials. The inner surface of the container preferably has a barrier layer to prevent absorption of flavors and oils from the cream material. The nozzle or outlet of the container will generally also include a barrier, since the nozzle is generally formed at the same time as the hose. The arrangement of the closure assembly, which is detailed below, has minimal contact with the paste-like material and therefore generally does not include a barrier layer.

The hose 10 also includes a top, forming a sloped conical shoulder 16 . At the apex of shoulder 16 there is a dispensing nozzle comprising a cylindrical portion 18 projecting upwardly from shoulder 16 coaxial with the hose. Threads are provided on the outer surface of the cylindrical portion for attachment of a closure described in detail below. A tapered dispensing nozzle 22 extends from the axial end of the cylindrical portion 18 to form an outlet for the hose. Between the nozzle 22 and the cylindrical portion 18 there is an annular groove 26 . In the embodiment shown in Figure 1. Nozzle 22 is substantially frustoconical with slightly concave sidewalls, while in other embodiments the nozzle is frustoconical with straight sidewalls. In preferred embodiments, nozzle 22, cylindrical portion 18 and shoulder 16 are integrally formed. In an alternative embodiment, the nozzle 22 and cylindrical portion 18 may also be formed as an assembly and welded or adhesively attached to the hose 10 .

The nozzle 22 shown in Figure 1 has a common central axis with the tube 12 and extends from the end of the tube a sufficient distance to facilitate dispensing of the material contained in the tube. Nozzle 22 preferably protrudes from shoulder 16 by about 0.75 to 2.0 cm. The dispensing outlet 24 is generally circular with a diameter of about 3m to 10mm. The size of the outlet 24 is generally not critical so long as the material in the tube is easily extruded from the tube. Nozzle 22 is configured to extrude the material in the tube a distance from the normal output point of the tube.

The cover 30 according to the first preferred embodiment of the present invention has a bottom cover 32 and a top cover 34 hinged to the bottom cover. The bottom cover 32 is substantially cylindrical, as shown in FIGS. 2 and 3 . The bottom cover 32 includes a cylindrical outer wall 36 depending from a top wall 38 . In preferred embodiments the outer wall 36 is the same size as the outer diameter of the tube 10, so that when the bottom cap 32 is seated on the tube 10, the outer wall 36 is substantially flush with the wall of the tube 12.

In the embodiment shown in FIG. 1 , the top wall 38 has a central opening 40 having a common central axis with the bottom cover 36 . The central bore 40 defines an annular lip 42 extending radially inward toward the center of the bottom cover 32 . In an alternative embodiment, the annular lip may be slightly lower than the upper edge of the bottom cover and may be intermittent to form a plurality of detents. In preferred embodiments, the annular lip 42 is substantially perpendicular to the centerline of the bottom cover. A major portion of the top wall 38 forms a slope 44 . A chime 46 extends around the perimeter of the ramp 44 and fits over the edge of the top cover 34 .

An annular inner wall 48 depends from the bottom surface of the top wall 38 and has a common central axis with the bottom cover. In preferred embodiments, the inner wall 48 has a uniform spacing inwardly from the outer wall 36 . In the embodiment shown in FIGS. 1 and 2 , the length of the inner wall 48 is slightly shorter than the length of the outer wall 36 . Internal threads 50 are provided on the inner surface of the inner wall 48 to cooperate with external threads on the hose 10 .

The bottom cover 32 is installed on the hose 10, the nozzle 22 passes through the central hole 40 of the bottom cover 32, and the thread 50 matches the thread 20 on the hose. The cap 32 is then threaded onto the hose until the nozzle 22 extends completely through the central bore 40 and the lower edges of the inner wall 48 and outer wall 36 contact the shoulder 16 of the hose 10 . In the embodiment shown in FIGS. 1 and 2 , the lip 42 of the central hole 40 of the base cover 32 snaps securely into the annular groove 26 of the nozzle 22 when the base cover 32 is fully seated on the hose 10 . Lip 42 is preferably a tight fit with nozzle 22 . The engagement between the lip 42 and the groove 26 also prevents the threaded connection between the bottom cap 32 and the hose from loosening. Manually unscrew the bottom cap 32 with sufficient force, the threads 50 and 20 force the bottom cap 32 away from the hose until the engagement between the lip 42 and the annular groove 26 is disengaged, and the bottom cap is removed from the hose.

The top cover 34 is connected to the bottom cover 32 via a living hinge assembly 52 . As shown in Figure 2, the top cover 34 has a cylindrical outer wall 54 of complementary dimensions to the outer dimensions of the bottom cover 32 so that the walls 54 and 36 are flush with each other when the top cover is closed. The outer wall 54 of the top cover 34 terminates in a lower end 56 which is inclined to the centerline of the top cover 34 and is complementary to the lip 46 of the bottom cover 32 . The top wall 58 connected to the outer wall 54 forms an upper edge 60 substantially perpendicular to the central axis of the top cover 34 . Depending from the inner surface of top wall 58 is an annular collar 62 . The collar 62 has a common central axis with the top cover. Inside the collar 62 is an inner collar 64 . Collar 62 will be in contact with the outer surface of nozzle 22 and collar 64 will be in contact with the inner surface of nozzle 22 . Collars 62 and 64 preferably form a snap fit connection with the nozzle.

As shown in FIG. 1 , the cap 30 is assembled on the nozzle 22 by screwing the bottom cap 32 onto the threads 20 of the nozzle 22 until the nozzle 22 protrudes through the central hole 40 and the lip 42 engages in the annular groove 26 . In various preferred embodiments, the size of the nozzle 22 extends beyond the lip 42 by about 0.2 to 1.5 cm. The top cover 34 is hinged to swing over the bottom cover 32 and close the hose. The annular collar 62 on the cap 34 is sized to contact the outer surface of the nozzle 22 to form a substantially fluid-tight seal. The inner surface of the outer wall 54 of the top cover 34 has a pawl 66 at its side portion, and a pawl 67 at its front portion, which can be snapped into the corresponding edges of the flange 46 of the bottom cover 32 and the protrusion 68, so that the top The lid remains in the closed position. Additionally, the raised portion 73 on the wall 71 adjacent to the hinge acts to force the rear wall portion of the top cover 34 outward when closed so that the pawl 67 latches more securely into the projection 68 of the bottom cover 32 . The edges of the bottom cover 32 and top cover 32 each include a concave surface 69 and 70 respectively to facilitate opening the top cover 34 .

When it is time to dispense the product contained in the hose, the top cap is flipped to the open position and a squeezing force is applied to the side wall of the hose to force the product contained in the hose out of the nozzle. The nozzle 22 protrudes a distance from the bottom cap to facilitate dispensing the product. The top wall 58 of the top cover 34 is inclined at about 5° to 15°, preferably about 10°, of the bottom cover axis to facilitate dispensing from the hose. The top wall 58 of the top cover 34 is slightly concave and is dimensioned such that the hose can stand upright on the top wall. This way, the hose can stand upright when not in use, reducing storage space. To suit the user's personal preference, the closure can be used either by flipping the top cap into the open position or by unscrewing the closure from the hose in a manner similar to a normal screw cap.

The top cover 34 is connected to the bottom cover 32 via a living hinge assembly 52 . Bottom cover 32 has an arcuate wall portion 71 adjacent hinge 52 extending upwardly from outer wall 36 through top wall 44 . As shown in FIG. 3, the wall portion 71 has two steps 72 and 74 spaced apart on either side of a higher step 76, respectively. A primary stabilizing living hinge 78 connects the rung 76 to the top cover 34 . A pair of snap hinges 80 and 82 are connected between the steps 72 and 74 and the top cover 34 . Each snap hinge includes an elongated portion 84 with side edges 86, 88 perpendicular to the bottom cover when the top cover 34 is in the closed position. The ends of the elongated portion 84 are connected to the steps 72 and the top cover respectively to form living hinges 90 and 92 . Snap hinges 80 and 82 are similar in construction.

The arrangement of the hinges 78, 80 and 82 provides a smooth appearance when the top cover is in the closed position so that the hinges are substantially flush with the side walls 36 and 54, as shown in FIG. In operation, the top cover 34 swings relative to the bottom cover 34 about a central hinge 78 which constitutes a pivot for the top cover 34 . Since the snap hinges 80 and 82 are spaced from the central hinge along the perimeter of the bottom cover, the hinges 80 and 82 provide an over-center snap action. When the top cover 34 is swung from the bottom cover past the point where snap hinges 80 and 82 are in the same plane as the center hinge, the top cover will snap to the open position. Likewise, when the top cover is swung past the same point towards the bottom cover, the top cover will snap to the closed position.

The closure is not limited to any particular hinge type and may be a three-bar hinge as shown in the drawings or a diaphragm hinge as in U.S. Patent No. 4,403,712.

Referring now to the embodiment shown in FIGS. 4 and 5 , the hose 100 includes a flexible, squeezable sidewall 102 attached to a frusto-conical shoulder 104 . Extending from shoulder 104 is a cylindrical portion 106 having a common central axis with hose 100 . Threads 108 are provided on the outer surface of the cylindrical portion 106 for connecting the soft cover 110 . The upper end of the nozzle 112 has an outwardly extending radial lip so as to define an annular groove 114 .

Cover 110 has a bottom cover 116 and a top cover 118 held together by hinge assembly 120 . The bottom cover 116 includes an annular outer wall 122 depending from a face wall 124 . The dimensions of the outer wall 122 are complementary to the dimensions of the hose 100 such that when fitted over the hose, the outer wall 122 is substantially flush with the hose. The annular inner wall 126 has threads 128 mating with the threads 108 of the hose 100 for connecting the bottom cap to the hose.

A duct 130 perpendicular to the axis of the bottom cover 116 is formed in the top wall 124. The duct 130 in the top wall forms an annular inlet 132. The inlet 132 has a common central axis with the bottom cover 116 and the inner and outer walls 126 and 122. As shown in FIG. 4 , the inwardly extending annular collar 134 is concentric with the inner wall 126 . A lip 136 extends radially inwardly from the lowermost end of the collar 134 . The conduit 130 terminates in an upwardly extending nozzle 138 that extends through the top wall 124 of the bottom cover 116 .

As shown in FIG. 4 , duct 130 defines an axial inlet passage 140 , a substantially horizontal passage 142 and an axial outlet passage 144 . The inlet channel 140 is coaxial with the inner wall of the bottom cover. Outlet channel 144 and nozzle 138 are offset from the central axis of the bottom cap toward the periphery to facilitate dispensing of the product contained in hose 100 . The top wall 124 is preferably inclined to the central axis of the bottom cap, further facilitating dispensing of the product contained in the hose. In the embodiment shown in FIG. 4 , the top wall 124 slopes downward from the hinge assembly 120 toward the opposite side of the bottom cover. The outlet nozzle 138 and outlet channel are disposed opposite the hinge assembly 120 .

The outer wall 122 includes a chime portion 146 around the perimeter of the bottom cover 116 . Wall portion 148 extends beyond top wall 124 to support hinge assembly 120 .

The overcap 118 is substantially similar to that of the embodiment shown in FIG. 1 , except that the annular collar 150 is offset from the central axis of the overcap to accommodate the offset nozzle 138 . An inwardly facing rib 152 engages the end of the nozzle 138 to seal the outlet passage 144 when the cap is in the closed position. Components of the top cover 118 and hinge assembly 120 that are similar in structure and function to the embodiment shown in FIG. 1 are given the same reference numerals but with the symbol '.

In use, the bottom cap 116 is assembled onto the threaded cylindrical portion 106 of the hose 100 . Bottom cap 116 is threaded into threads 128 to bring bottom cap 116 into the position shown in FIG. 4 . Tightening the bottom cap 116 over the threads 128 also snaps the inlet collar 134 into place in the annular groove on the nozzle, forming a liquid tight seal. As shown in FIG. 4 , the upper end of the nozzle 112 is substantially flush with the lower surface of the horizontal channel 142 . In this embodiment, the end of the nozzle 112 is lower than the upper surface of the bottom cover 116 . Once the bottom cap is installed on the nozzle, the product contained in the hose can be dispensed by squeezing the side walls of the hose to force the product in the hose through the nozzle 112 and passage to the outlet nozzle 138 . Closing of the top cover 118, connected to the bottom cover 116 by snap hinges, is accomplished by flipping the cover 188 over the bottom cover. In the closed position, the edge of the top cover 118 abuts against the sloped lip of the bottom cover. The collar seals the opening against the nozzle.

The embodiment shown in Figure 6 differs from the embodiment shown in Figures 1-4 in that the hinge between the bottom cover and the top cover does not rise above the bottom cover, but is a continuation of the top wall of the bottom cover. If the hinges used are the three hinges shown in Figures 1-4, the two sides can be connected to the bottom cover slightly lower than the top wall of the bottom cover. This is a common construction for such hinges, where the hinge is essentially a continuation of the top wall. This embodiment has certain structural advantages over the elevated embodiment shown in FIGS. 1-4. In this embodiment, living hinge assembly 252 is substantially a continuation of top wall 238 . Attached to the top wall is a cylindrical wall 236 . The opening of the hose extends upwardly through a central opening 240 defined by an annular lip 242 . The top cover has a cylindrical wall 254 and a top wall 258 and also has annular collars 262 and 264 . The detents 266 and 267 function to hold the top cover in the closed position, interlocking the detents 267 and projections 268 . The hinge structure is basically the same as the embodiment shown in Figs. 1-5.

Another embodiment shown in Figure 8 has a cam arrangement connecting the lid to the container. Hose 160 and cap assembly 172 are similar to the embodiment shown in FIG. 1 , except for the threads provided on the bottom cap and nozzle.

In the embodiment shown in FIG. 8 , the hose 160 has a conical shoulder 162 and a cylindrical portion 164 . The axial end of the cylindrical portion 164 has an annular groove 168 and a conical dispensing nozzle 170 . Cover 172 has a bottom cover 174 and a top cover 176 connected together by a living hinge assembly 178 . The bottom cover has a top wall 180, a depending inner wall 182 and a depending outer wall 186, similar to the embodiment shown in FIG. An axial opening 188 extends through the top wall. An inwardly directed annular rib 190 extends around opening 188 .

The inner surface of the inner wall 182 has a cam member 192 inclined to the central axis of the lid. As shown in Fig. 8, the cam member has a slope. The cylindrical portion 164 of the hose has a cam member 194 corresponding thereto. Cam members 192 and 194 are integrally molded on the hose and cap, respectively. As shown in Figure 8, the cam member acts like a normal thread to screw the bottom cap onto the hose so that the nozzle extends through the opening 118 causing the rib 190 to snap into the annular groove 168 of the nozzle. The cam members are sufficiently flexible so that once the nozzle is installed in the opening 188, further rotation of the cap relative to the nozzle will cause the cam members to engage each other. Turning the cap counterclockwise will cause the cam member 192 on the cap to engage the cam member 194 on the hose, lifting the cap and disengaging the rib 190 from the annular groove 168 . Once the rib 190 is disengaged from the annular groove 168, the cap can be easily screwed off the nozzle. The cam member in this embodiment allows the closure to be turned clockwise to any desired position without the risk of over tightening and without the risk of the bottom cap becoming loose from the hose.

Another embodiment of the present invention shown in FIG. 9 has a bottom cover 186' and a top cover 176' mounted on the hose 160'. The structure of the bottom cover, top cover and nozzle is basically the same as the embodiment shown in Fig. 8, the difference lies in the way of connecting the bottom cover to the hose. Accordingly, identical parts are given the same reference numerals plus the symbol '.

In this embodiment, the bottom cap 186' is permanently attached to the hose by means of a snap connection, thus preventing the bottom cap from being easily detached from the hose during normal use of the hose. As shown in Figure 9, the inner wall 182' of the bottom cover has an annular interlocking rib 200 extending radially inwardly towards the central axis of the bottom cover. In the embodiment shown in Figure 9, the annular rib 200 is a continuous rib. In alternative embodiments, the annular rib may also be intermittent to form a plurality of detents around the inner surface of the inner wall 182'.

The hose 160' has a conical shoulder 162' and a cylindrical portion 164'. The axial end of the cylindrical portion 164' has an annular groove 168' and a dispensing nozzle 170'. A central annular rib 202 is located approximately in the middle of the cylindrical portion. The annular rib 202 has a sloped upper wall sized to complement and interlock with the annular rib 200 on the bottom cover.

Bottom cap 186' is assembled to the hose by sliding nozzle 170' through opening 188' in the bottom cap. The bottom cap is pressed down on the nozzle until the annular rib 200 engages the annular rib 202 and the annular rib 190' defining the axial opening in the bottom cap snaps into the annular groove 168'. In an alternate embodiment, annular rib 190' and annular groove 168' may not be provided when annular ribs 200 and 202 are provided. In each case, however, the upper edge of the bottom cap preferably forms a tight seal with the spout to prevent impurities and extruded product from accumulating between the bottom cap and the spout. The bottom cap can be removed from the hose using sufficient pulling force to break through the engagement between the ribs 190', 200 and the ribs 202 of the groove 168'.

The closure in the preferred embodiment is molded of plastic as a unitary part. Suitable plastics include, for example, polyolefins such as polyethylene, polypropylene and polymers thereof, and the closure is typically formed by injection moulding.

The hose is likewise made of a suitable plastic such as polyolefin. In the preferred embodiment, the nozzle, shoulder and body are molded as a unitary component. The tube and closure are particularly suitable for most one-time use of smaller quantities of viscous materials such as toothpaste. The cap fits easily and efficiently on the hose, allowing the hose to be closed after each use.

The cap can also be removed from the hose when the material in the hose has been used up. The cap is removed from the nozzle by turning the cap relative to the hose to loosen the threads between the bottom cap and the hose so that the lip of the bottom cap disengages from the groove in the nozzle. In this way, the closure can be reused on another hose.

The foregoing describes an illustrative preferred embodiment of the present invention. Obviously, various modifications can be made by those skilled in the art without departing from the scope of the invention as defined in the claims.
