Description

PAPA DEVICE AVOID THE EXTRAVITION OF THE BOTTLE PLUG AND IMPROVE THE HYGIENE IN THE DISPENSED TECHNICAL FIELD The. present invention relates to liquid containers - for human or animal consumption, of the type used to feed infants, commonly known as baby bottles, and specifically, with devices to prevent contamination by external agents of the means for dispensing the liquid, so-called mammals, and more specifically, with means that prevent the loss of said devices and improve the hygiene conditions in the transport and dispensing of the liquid to the infant.

BACKGROUND OF THE INVENTION A problem that frequently occurs during the use of containers with removable lids, is that the lid can easily get lost when it is removed from its position of use on the container in order to have access to the contents. There are many examples in the field of containers in general that are aimed at solving this problem, proposing various alternatives to keep the lid close "to the container and even to hold it while the lid is not in use.

The problem described is aggravated when the container in question is one intended to conserve materials intended for human or animal consumption. It is well known to people who have fed infants by bottle, that it is easy to lose the cap that covers the cap with a bottle bottle, either by the inadvertent expulsion of the cap during transport, or by loss in the bottle. time to remove it to access the bottle and feed the infant, and during the time that the feeding lasts, time in which the plug is usually placed away from the infant to prevent it from causing any damage. The loss of the cap makes it impossible to re-cover the bottle, either to protect the content not used for later use, or for its transport and future use. The only way to replace the cap is by buying a spare.

Another problem, especially serious is that the area of the plug that has to be in contact or proximity to the bottle (to be sucked directly by the infant), is exposed to contamination, for example by dust, by insects or by any other source; In the solutions proposed up to now, the cap when it is removed from the cap with a bottle is open to contact with the environment and therefore the infant is susceptible to acquire a contaminant (bacteria, fungi, etc.) through the bottle. has taken contact with the plug.

Some examples of the alternatives proposed to solve the problems raised are described below.

In the field of containers in general, there are some interesting applications especially for garbage containers.

U.S. Patent No. 3,363,924 (Remig, 1968) presents a typical garbage container, in which the lid is held by two diametrically opposed elastic elements located from the vertical posts of the lid handle to the handles located diametrically opposite on the body of the container; To help the coupling, the elastic elements are attached to the handle of the lid and fastened to the handle of the container by means of hooks.

U.S. Patent No. 6,041,960 (Leal, 2000) is an alternative embodiment that takes advantage of the configuration of the container with handles close to the mouth thereof and the concavity of the lid to use as a fastener a semi-flexible strip that is fastened firmly at the midpoint, highest, of the lid; it is folded down and the ends of the strip are attached to the handles on the body of the container; in this way the strip itself exerts a downward pressure on the lid, to keep it closed. To release the lid, one of the ends of the strip is released, which is removed by sliding upwards and then hanging from the other handle.

In U.S. Patent No. 5,156,292 (Ross, 1992) the lid of a container is held from two diametrically opposed ends by a pair of elastic bands which are attached to a common hook in the lower part of the container; the hook is attached to a groove or groove in the lower end of the container. The lid is held in place by the pressure in the downward direction exerted by the elastic bands.

U.S. Patent No. 5,090,583 (Hoffman et al., 1992) discloses a cap for a container, which is held close to said container by means of two flexible arms which fasten it to the body of the container by means of a ring, and which are located in two diametrically opposite points of said plug; . To open the container, it is necessary to break one of the arms so that the cap moves longitudinally outward from the tip of the container when the second arm is flexed.

In the field of containers of the bottle type, U.S. Patent No. 5,361,918 (Mason, 1994) describes a cap that is attached to the bottle cap of a bottle and also has the function of keeping inside of your body, a certain amount of a material such as powder from a food formulation; the device is attached to the cap with a bottle bottle, and can be separated from it to allow access to the bottle as well as the contents of the bottle and the device itself.

U.S. Patent No. 5,653,353 (Otto et al, 1997) describes a bottle cap, which is attached by means of a removable strap to the cap itself that holds the bottle to the bottle; As can be appreciated, this simple device solves the problem of keeping the cap attached to the body of the bottle, in order to avoid the loss of the bottle, however the problem of contamination of the interior of the stopper and therefore of the bottle is still maintained. when the cap is repositioned on it.

United States Patent No. 6,302,286 (Whiterspoon, 2001) describes a bottle in which the bottle cap is kept close to the bottle when it is not being used to cover the bottle, by means of an arm that is held at one end to the stopper and at the other end a. a ring that is arranged around the neck of the body of the bottle and held in place by the coupling of the lid with the bottle, which is screwed on the upper part of the body of the bottle. The ring can rotate freely and can also move along the neck of the bottle; the arm is sufficiently flexible so that the cap can be adjusted on the lid with the bottle to protect it from contaminants, as well as to allow the bottle to be released for use by the infant. The cap, when it is not in its position of use, protecting the bottle, rotates freely around the body of the bottle, exposing its interior surface to the elements, with the consequent risk of contamination.

A different approach to bottle component handling problems is presented in United States Patent No. 6,123,210 (Kim, 2000), wherein to prevent the loss of the bottle cap when it is in use by the infant , the plug is attached to a second site designed for this purpose in the body of the bottle; the position of this second location allows the bottle and cap assembly to be used to correctly position the bottle-for proper suction by the infant (avoid sucking air bubbles when the infant is lying on its back).

OBJECTIVES OF THE INVENTION In light of the limitations and problems presented by the developments hitherto proposed in the prior art, it is an object of the present invention to provide a device for keeping bottle caps available and close, while the bottle is being used by the patient. lactating, so that they do not get lost and allow an adequate degree of hygiene to be maintained in the handling of said bottles once the infant has stopped using it.

It is another object of the present invention to provide a device that allows the cap of a bottle to be held in a fixed location close to the bottle and attached to the body of the bottle for application on the means for dispensing the fluid once it has been used. the infant It is another object of the present invention to provide a device which makes it possible to maintain the bottle cap in proximity to the bottle and to keep the inside of said cap free of contact with contaminants in the medium, such as dust or insects. - It is still another object of the invention to provide a device that allows to keep the bottle cap in proximity to the bottle, with elements that allow easy and quick fixation by a user in charge of feeding the infant.

It is a further object of the present invention to provide a device which makes it possible to maintain the bottle cap in proximity to the bottle, even when it is moved from one use position to another.

These and other objects and advantages of the present invention will become apparent in the light of the following description, which is accompanied by a series of figures for preferred embodiments of the invention, which should be understood to be elaborated for illustrative and non-limiting purposes. of the teachings of the invention.

DETAILED DESCRIPTION OF THE INVENTION The following description will be referred to the accompanying drawings described above, which should be understood as illustrative of the invention, and not "limiting the scope of the same." The common elements in the figures, have the same reference numbers in all of them.

In order to avoid confusion regarding the use of certain terms, the following meanings are agreed: "mamila" means the ampule of elastic material, usually latex or soft plastic, through which the liquid flows the container to the outside. by the sucking action of the infant; "lid" refers to the normally internally threaded ring that holds the "bottle" and holds it against the mouth of the container; by "baby bottle" s & will understand the container assembly, "lid" and "mamila" described above; finally, the references to the term "cap" have to be understood that they are made towards a hollow device that serves to cover and protect the cap-mamila pair.

The present invention relates to modifications that can be made to a conventional baby bottle or that can be incorporated into the factory design, such that it is allowed to keep the cap close to the body of the bottle at all times, in such a way as to minimize the possibilities of contamination of its inner surface of possible contact with the bottle.

Figure 1 is a side view of the baby bottle (10 (5) incorporating the additional elements and modifications in accordance with the present invention) The bottle consists of a container open at one end whose body (110) is essentially cylindrical Conventionally, at the "upper" end of the cylindrical body (110), open, a neck is formed to which a lid (120) can be attached generally in a threaded relation to each other, the lid (120) in turn, supports a bottle ( 130) and the cap (120) and canister (130) can be covered by a cap (140) to prevent contamination, as is known to users of conventional bottles, so that the infant has access to the bottle and can suck the fluid in the bottle, the cap (140) must be removed in order to leave the bottle (130) exposed; the stopper is located during the time the infant is using the bottle (100), on some nearby surface or sheltered somewhere else, with the risk of being lost or simply exposed to contamination by external environmental agents.

In the modification proposed in the present invention, the plug (140) is attached to the body (110) of the baby bottle (100) by means of an articulated joint (160); one end of the articulated joint (160) is attached to a point of the plug (140) close to the open base, by some of the techniques known in the art, such as by an adhesive; the other end of the articulated joint (160) is fastened to, or is formed in, a sliding element with a general form of reel or pulley (170) which is finally confined to the interior of the hollow of an elongated channel (150) in the form BC "with the opening directed towards the outside of the bottle.

To access the bottle (130), the plug (140) rises in the direction indicated by the arrow "A" of Figure 2, on the set of bottle (130) and cover (120), thanks to the movement of the articulated joint (160) in combination with the length of the slidable element (170), so that its inner surface does not touch the surface of the bottle (130); the cap (140) is then rotated in the direction indicated by the arrow "B" of Figure 2 around the articulated joint (160) so that the slidable member (170) can slide freely in the downward direction of the baby bottle, as shown by the arrow "C".

During its travel, the plug (140) can be rotated either clockwise or counterclockwise, as indicated by the double-headed arrow WR "of Figure 3, about the axis of the slidable member (170) and continuing to slide downward according to the arrow "C." Finally, when reaching the lower end of the bottle (100), the plug (140) is rotated in the articulated joint (160) in the direction of the arrow WD ", of figure 4, to be coupled to the bottom of the body (110) of the baby bottle (100) where alternate means of holding and supporting the stopper are located, these means preferably being the bottom of the baby bottle modified by adding a "blind" lid (168). ) around which the stopper (140) is adjusted, thereby covering the interior of said stopper - (140).

The "blind" lid (168) is basically an element identical to the lid (120) that supports the bottle (130), where the hole through which said bottle would have been sealed to give it a smooth finish from the outside; this "blind" lid is fastened to the bottom of the body (110) of the bottle (100) by any known technique, such as by adhesion or heat sealing, or in an alternative mode the bottom of the bottle body can be configured from origin adopt the contour of the "blind" lid (168), thus providing the place for the adjustment of the cap (140) when the bottle (100) is exposed to the bottle (130) so that it can be used by the infant.

It is clear that in this new position, the plug (140) is kept within reach of the hand when it is necessary to reposition it on the bottle (130) once the infant stops using it, and by virtue of being attached to the bottom of the bottle (100), the inner surface of said plug (140) is not exposed to the environment and therefore the chances of contamination are diminished.

Some details of the constituent elements of the invention and their mode of use according to the present invention are offered below.

Commercially available baby bottles and bottles are accompanied by a plug (140) which for the purposes of the present invention has the shape shown schematically in Figures 6a and 6b and which in most conventional embodiments includes approximately the same configuration; an open lower zone, of cylindrical shape (142) (indicated by the lower keys of figures 6a and 6b), whose internal diameter is designed to surround and adjust to the outer periphery of the cover (120) to which it is intended; on this lower area (142) there is located a hollow upper zone (144) with hemispherical shape (indicated by the upper keys of figures 6a and 6b), the height of this upper zone is such. which allows to accommodate the bottle (130) supported on a conventional lid (120) in its interior. As mentioned, the stopper (140) is used to isolate the cover (120) and the mammilla (130) assembly by being slid over them, thus preserving the maze (130) from contact with air and other means of contamination.

Still referring to Figures 6a and 6b, for the purposes of the present invention, an articulated joint element (160) is held to this stopper (140) which, in the illustrated embodiment, is formed by two bodies, one of which it moves hingedly with respect to the other around two lateral projections that serve as an axis and that are inserted in appropriate holes located in the walls of the other body, same that at the same time are placed on both sides of the first body.; the first body (162) which is attached to, or reconfigured to form a slidable member (170) which is described below, offers a point of support to a rotating member (164) which allows the rotation of the two bodies of the articulated element (160) between them; the turning element (164) is represented as a pair of projections that move rotationally inside respective circular holes in the first body (162), this turning element (164) in turn is attached to, or forms a second body (166) which is finally firmly secured by any known technique to a place located in the lower area (142) proximate the lower edge of the stopper (140), in the cylindrical area thereof (142).

The sliding element (170) has the general form of a reel or pulley, constituted by two cylinders of low height between which another cylinder of smaller diameter and greater height is located, as can be seen in both Figures 6a and 6b. The free end of the slidable element (170) is housed by a channel (150) running vertically along the outer face of the body (110) of the modified baby bottle (100) of the invention, as illustrated schematically in FIG. Figure 5, and wherein it is further appreciated that said channel extends from the lower end of said body (110), to a height approximately equal to that of the base of the cover assembly (120) and the bottle (130). It will also be noted that for the plug (140) to be able to be adjusted in place either on the lid (120) or on the alternate means (168), it is necessary to perform a vertical movement, represented by the arrows "A" and? "of Figures 2 and 4 respectively, this vertical movement is provided by the" free "length of the element (170), that is, the distance that can be moved in the upward or downward direction at the ends of the channel (150) and which corresponds to the length of the central element of the "spool", the maximum height of the body of the cap (120) being - The following Figures are intended to illustrate schematically the operation of the channel (150) and the element assembly articulated joint (160) and sliding element (170) Figure 7 is a schematic representation of a section of said channel (150) in which a cross section has been made shown by the dashed line to allow observing that the slidable element (170) occupies the free space inside the channel (150), whose upper ends (150 ') and (150") are folded inwards thus decreasing the free space and preventing the lower end (172) of the sliding element ( 170) 'in the form of a cylinder of low height, can exit said free space inside the channel (150); this is illustrated in Figure 8a which is a top view of a section of the channel (150) as illustrated in Figure 7 and Figure 8b which is a cross sectional view from the plane defined by the line HH of Figure 8a; in general, the part of the slidable element (170) that occupies the interior of the channel can have any shape as long as it can slide inside said channel (150), and that has a cross section capable of freely sliding along the length of the channel (150). narrow slot determined at the open end of the channel (150) by the edges (150 ') and (150"), and that said section into the channel (150) can not fully exit through the narrow slot determined between, the edges (150 ') and (150"); note further that the upper disc in the slidable member (170) is also not restricted to said discoidal shape, which is assumed here only for purposes of illustrating the connection between the connecting element (160) and the slidable member (170).

Continuing with the description of Figure 7, the possibility of rotation, indicated by the arrow MF ", is illustrated around the axis of the slidable element (170) in order to meet the requirement of inversion of the plug (140) for the purposes of occupying the two positions described in the two possible positions of use illustrated in Figures 1 and 5. It also indicates the sliding path of the slidable element (170), which along the channel (150) is longitudinally straight, but that at the end of the channel (150) can be changed up to a maximum angle of 90 °, as illustrated in Figures 9a to 9f.

Figure 9a is a cross sectional view along a section of the channel (150) including one of the ends thereof, and where the slidable member (170) is proximate said end; Figure 9b is a front view from the end of the channel (150) where it can be seen that the sliding element (170) can not exit because the front edges of the channel (150) follow the shape of the upper edges, ie , bent towards the inside of the channel narrowing the sliding groove.

Figure 9c illustrates the slidable element (170) at the end of the channel (150), where it can initiate a turn with respect to the illustrated horizontal of the channel to continue its sliding on the corner of the edge of said channel (150); Figure 9d shows the front plane view with the slidable element inclined with respect to the front of the end of the channel (150).

Figure 9e schematically shows the slidable element (170) having completed a 90 ° turn at the end of the channel (150) and the front plane view of Figure 9f allows to appreciate the impossibility of the sliding element leaving its confinement to the interior of the channel (150), although it can be seen in Figure 9a that the element 170 has the possibility of projecting outwards from the edge of the channel (150) at a distance equal to the length of its body between the discoidal ends, which is useful in the method of covering and uncovering the mammilla (130) and lid (120) assembly as described above with reference to Figure 2.

The characteristics of the channel (150) illustrated in Figures 7, 8a and 8b and 9a to 9f, of allowing the change of orientation of the slidable element (170) without risk of leaving the channel (150) allows that at the ends close to the corresponding ends of the body (110) of the modifbaby bottle (100) of the invention, the stopper (140) can be placed on the bottle (130) in order to cover it, in the first position of use illustrated in Figure 1, or just below of the bottom of the body (110) of the baby bottle (100) as illustrated in Figure 5; in both cases, and thanks to the fact that the open base of the cap bell (140) is sufficiently loose, it can occupy its positions by contacting the base of the lid (120) or that (168) at the bottom of the body ( 110) of the bottle (100), respectively.

In an alternative embodiment, and taking into account the object of the invention in terms of preserving the hygiene of the internal surfaces of the lid to avoid contamination by contact or exposure to air, an additional element is used, represented by the numeral (200) in Figures 10 to 12, and that it is a guard ring that is fixed to the base of the lid (120) proximate to the body (110) of the baby bottle (100); the inner diameter of said guard ring (200) is such that it allows the plug (140) to enter, as shown in Figure 11 by the arrow "K", so that said plug (140) can be moved over the lid (120) and fit it, to be as illustrated in Figure 12. It can be seen that to allow entry the plug (140) held by the articulated joint (160) to the sliding element (170), is provided to the ring guard (200) with a slot (210); it can also be seen that the height of the guard ring (200) is slightly greater than that of the base of the cover (120).

Although preferred embodiments of the present invention have been described where the device is applto a conventional baby bottle subsequent to its manufacture as an addition made by the user, it will be apparent to a person skilled in the art of bottle making that the Modifications and additions to the structure of a conventional bottle can be made at the time of manufacture, as mentioned during the description.It will also be evident that it is possible to make modifications to the elements described and illustrated with reference to the preferred embodiment, which however, they should not be considered as going beyond the scope of the present invention, which should be understood from the following claims.
