Igo, 8342 Woodley Ave., Sepulveda, Calif. 91343 Filed Oct. 5, 1966, Ser. No. 584,384 13 Claims. (Cl. 215-41) ABSTRACT OF THE DISCLOSURE base portion is further provided with a socket means adapted to detachably accept and seal with the dispensing mouth of a bottle.

The present invention relates in general to a combination receptacle and bottle sealing apparatus and more particularly to an apparatus which is adapted to seal either bottles utilizing threaded sealing means or those sealed by compressible sealing caps, While concurrently providing a compact receptacle for receiving liquids.

In many instances, it becomes desirable, or necessary, to seal bottles of various common configurations before the contents thereof have been totally consumed. To this end, a wide variety of seals including spring biased, plunger type, and threadably engaging configurations have heretofore been proposed. These devices while permitting bottles to be sealed, do not accommodate a multiplicity of applications but are singularly restricted in use to a distinct variety of bottle.

In addition, each of these types of bottle seals requires the consumer to drink directly from the bottle itself unless a separate drinking container is available. Consequently, when it is desired to share the contents of the bottle, each consumer must, under the aforementioned circumstances, risk the possibility of germs and disease being transmitted by the bottle mouth. Under normal conditions, it is generally impractical and often impossible to cleanse the area of oral contact because of the lack of facilities. Consequently, the risk of germs being transmitted is correspondingly increased by the amount of individuals who desire to drink from the bottle.

The use of glasses and cups have heretofore been restricted in many every day life activities such as camping, picnics and outings as well as while driving in a car because of their bulk and the danger of their breaking, being crushed or getting lost. One attempt to develop a sealing cap and drinking vessel resides in the disclosure of US. Letters Patent 3,159,298 that set forth a closure cap including a frusto-conical body open at one end and closed at its other end. Near its closed end, the cap is provided with a screw thread molded on the inner curved surface thereof adapted to be coupled with mating screw threads carried on the outer extremity of the bottle neck. Supported from its closed end, there is provided a substantially rigid and non-collapsible skirt that encircles the bottle neck when the cap is coupled thereto so that the annular terminating end of the skirt couples in sealing relationship with the flared portion of the bottle where the body thereof merges with the neck. However, this prior device is totally unsuited for coupling with a bottle mouth intended to receive a cap of the compressible type.

The invention of the present application overcomes the 3,381,838 Patented May 7, 1968 aforementioned disadvantages in that it permits the utilization of a drinking container adapted for varying utility having minimum bulk and weight while providing a design which is sturdy, economical to manufacture, and simple in its construction and operation. Perhaps more importantly, the subject invention permits the user to remove and cleanse the container after every usage, if desired, as well as to protect the bottle and consumer from possible chipped or sharp edges on the bottle mouth. A duality of sealing means is provided for attachment to common and/ or conventional bottles which allows a much greater utilization of purpose. A collapsible and telescoping relation between the wall sections of the sealing means also acts to absorb shocks when the apparatus is in the retracted position and thereby affords greater protection against breakage. The novel unitary construction of the receptacle wall when in the retracted or folded position acts as a cushion and therefore functions cooperatively with the sealing means to resist detachment.

The problems and difiiculties encountered with conventional bottle seals and drinking containers are obviated by the present invention which provides, in one embodiment thereof, a novel apparatus having a central portion integrally formed with a collapsible and foldable unitary side wall adapted to coaxially extend in either of two directions to provide a receptacle for a drinking vessel with the central portion serving as the vessel bottom. One side of the central portion is provided with means for sealingly engaging with a bottle requiring a compressible fit while the other side of the central portion is provided with means for sealingly engaging a bottle requiring a screw thread fit. A feature of the invention resides in the fact that the side wall portions provide a series of spaced apart rings about the central portion when the side wall is folded or collapsed.

Therefore, it is a primary object of the present invention to provide a novel drinking vessel apparatus having a telescoping unitary side wall with a threadably engaging sealing means disposed about the bottom of a receptacle portion and having a discrete compressible sealing means located adjacent the base of the receptacle.

It is another object of the present invention to provide a novel dual bottle sealing means in combination with a drinking receptacle having a unitary extendable side wall.

Another object is to provide a combination receptacle and dual sealing means for attachment to conventional bottles and which'is compact, economical to manufacture and is of simple construction.

Still another object is to provide a combination receptacle and dual bottle sealing means wherein the retracted side wall acts in cooperative relation to the sealing portion so as to resist detachment from the bottle.

Another object is to provide a combination receptacle and dual sealing means of unitary construction which is simple to clean and which may be attached to both types of conventional bottles.

The foregoing objects, advantages, features and results of the present invention, together with various other objects, advantages, features and results thereof which will be evident to those skilled in the art in the light of this disclosure, may be attained with the exemplary embodiment of the invention described in detail hereinafter and illustrated in the accompanying drawings, in which:

FIGURE 1 is a perspective view of the novel combination receptacle and bottle sealing means of the present invention shown as being in the retracted position and installed on a conventional bottle;

FIGURE 2 is an enlarged view, partially sectionalized of the combination receptacle and bottle sealing means and illustrating the dual sealing means;

FIGURE 3 is an enlarged view of the combination receptacle and bottle sealing means shown in FIGURE 1 and illustrating a portion thereof broken away to expose the compressive sealing means and associated bottle neck and being in the retracted position;

FIGURE 4 is an enlarged view of the combination receptacle and bottle sealing means shown in FIGURE 1 and illustrating a portion thereof broken away to expose the threaded sealing means and associated bottle neck and being in the retracted position; and

FIGURE 5 is an enlarged cross-sectional view taken in the direction of arrows 55 of FIGURE 2 and illustrating the plurality of finger engaging grooves disposed about the periphery of the receptacle wall.

Referring to FIGURE 1, the novel combination receptacle and bottle sealing apparatus of the present invention is illustrated in the general direction of arrow and is shown as being detachably secured in its retracted position to a conventional bottle 12 having a neck portion 14. The apparatus of the present invention, when in the retracted position, affords easier storage and the inherent cushioning effect of the configuration acts to prevent detachment as well as breakage of the bottle 12 due to external forces.

FIGURE 2 illustrates apparatus 10 detached from the bottle 12 and in its extended or unfolded position ready to be filled. The apparatus 10 includes a base portion indicated in the general direction of the arrow 15. The base 15 has a flat annular flange 16 protruding about its periphery which serves to facilitate easier attachment and detachment from the bottle 12 as well as to support the present invention and its contents when in its extended position.

Interior of the flange 16, a bottle receiving cavity 18 is defined by the wall 20 and the partition 22 extending transversely across the base 15. The cavity 18 is adapted so as to receive the neck 14 of a conventional bottle and is constructed to be detachably secured to the bottle 12. The wall 20 has a shoulder 24 of reduced diameter 12 having a conventional locking shoulder on its head and is placed thereon by pressure applied to the flange 16 such that it is bent downwardly and inwardly until the interior annular portion 24 of the flange 16 is forced beneath and into reliable engagement with the locking shoulder, as seen in FIGURE 3, as found on a conventional bottle.

Adjacent to the shoulder 24, an edge 26 is beveled outwardly and by reason of a rounded lip 28 of the bottle 12, thereby affords a free annular space 30 around the circumference of the bottle neck 14. The annular space 30 acts to receive any suitable instrument for prying the flange 16 and to facilitate easier detachment and attachment. Under normal conditions, however, the force required for engagement or disengagement of the apparatus 10 from the bottle 12 would not require a prying action but would in the case of small children afiord a distinct advantage.

As is best illustrated by FIGURE 3, the wall 20 and the partition 22, when in compressible engagement with the neck 14 of bottle 12, serves to seal the contents thereof at

sealing points

32, 34 and 36 and thereby prevent liquid from escaping through the connection. These plurality of sealing points act as redundant sealing means to assure a complete and pressure tight seal. It is to be noted that any extension or retraction of the apparatus 10 will not affect the seal since it is independent of the telescoping action thereof.

A collapsible side wall 38 of the present invention is comprised of a plurality of non-uniform annular and

coaxial sections

48 and 56 which are of alternately rigid and flexible thicknesses but which comprise a unitary structure. The base portion 40 of the side wall 38 is fabricated of a substantially rigid cross section for which mold setting rubber of approximately 60 shore is suit able. Being rigid, the base section 40 is adapted as to carry the weight of the upper portions of the side wall 38 as well as the contents of the apparatus 10.

Interior the annular shoulder 42 and adjacent thereto lies a funnel 44 which is adapted to receive the neck 14 of a conventional bottle having a threadably engaged cap or seal as illustrated in FIGURE 4. The larger diameter of the funnel 44 permits the neck of the bottle to be guided or directed into engagement with the small diameter portion. The base portion 40 defining the funnel 44 is threaded as indicated by numeral 5% such that the bottle fits substantially flush against a wall surface 52 of the transverse partition 22. The thickness of the base section 40 permits the apparatus 10 to be in rigid engagement with bottles having either the threaded sealing cap or the conventional locking shoulder.

A plurality of grooves 54 are disposed about the outer periphery of the base section 40 to facilitate easier handling of the apparatus. The thickness of the side wall 38 of the base section 40 adjacent the grooves 54 is sufficient so as to restrict the flexing or bowing of the container when being held as shown in FIGURE 5. The grooves 54 are tapered and of sufficient area so as to receive the width of a human finger.

Intermediate a pair of

flexible shoulders

42 and 59 of the side Wall 38, is the reduced intermediate Wall section 56. Preferably the wall. section 56 is of a slightly funnel shape rather than cylindrical to facilitate the required folding action. The shoulder 59 is therefore of slightly larger diameter than the shoulder 42. The wall itself is fabricated from a material which affords a sub stantially rigid structure and which is flexible when comparatively thin material is employed. Such a material may be a mold setting rubber of approximately 60 shore. The

shoulders

42 and 59 are chosen to be of sufficient thinness so as to permit the intermediate wall section 56 to be folded without sacrificing its ability to carry required loads.

The width of the

shoulders

42 and 59 is a function of the material from which the wall 38 is fabricated. The horizontal or transverse

annular areas

58 and 60 while permitting the intermediate wall section 56 to fold, cannot be so large as to permit the fluid resting thereon to overcome the resistance to folding afforded by the nature of the material itself.

The top wall section 48 is fabricated of a suflicient thickness so as to be substantially rigid. Similar to the intermediate wall section 56, the top wall section is slightly funneled in shape from the shoulder 59 to the annular edge 64. The flexibility of the intermediate wall section 56 permits the top wall section 48 to move in telescoping relation with respect to the base section 40 and the height of the wall sections is chosen such that the shoulder 59 rests on a shoulder 66 of the flange 16 when the container 10 is in the retracted position.

Therefore, it can be seen from the foregoing that the novel drinking vessel of the present invention includes a hollow base portion 40 having a central partition 22 extending transversely through the hollow base of the base portion which divides the base portion into a pair of coaxial sockets, each having a sealing means 24 and 50, respectively, capable of accommodating a sealing detachable coupling with the bottle neck of either the threadable or compressive cap types. One sealing means of the pair includes an inwardly projecting annular rib or bead adapted to be removably placed on the bottle neck of the compressible type while the other sealing means includes internal thread turns adapted to mate with the threaded bottle neck of the threadable cap type. The flexible partition 22 disposed between the pair of sealing means serves as a common wall wherein one surface thereof functions as the bottom for a fluid receptacle formed from the

telescoping sections

48 and 56 of the flexible side wall 38.

By folding or collapsing the side wall 38, a compact storage configuration is derived for the receptacle which is readily carried on the neck of a bottle of either the compressible cap type or threadable cap type. The varying side wall thicknesses of the coaxial wall sections permit the receptacle to be folded and unfolded with relative ease. Although the extendable receptacle is shown to unfold from the recess having the threaded sealing means 50, it is to be understood that annular flange 16 may be formed adjacent the opening to the recess having sealing means 50 while the receptacle is arranged to unfold from the base portion so that the recess having the inwardly projecting lip may serve as the bottom of the drinking vessel.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
