BOTTLE CLOSURE Filed Jan. 2, 1964' United States Patent Ofi ice 3,,l8,5l Patented Apr. 27, 1965 3,189,515 BGTTLE CLOSURE Erik A. Lindgren, 27 33 Ramona St., Palo Alto, Calif. Filed .l'an. 2, 1964, Ser. No. 335,203 7 Claims. (Cl. 215-52) This invention relates to a bottle stopper or closure and, more particularly, to a reusable stopper having a body adapted for insertion into the neck of a bottle, the sides of the body being resiliently expansible into sealing engagement with the bottle neck.
There have been many designs for expansible bottle stoppers but, for the most part, these structures have been complex, with many providing anrinherently non uniform distribution of sealing pressure against the interior surface of the bottle neck.
It is one object of this invention to provide an improved expansible stopper for a bottle.
It is another object of this invention to provide an improved, reusable bottle stopper which has expansible side walls and which employs a minimum number of parts.
It is an additional object of this invention to provide an expansible stopper which provides an inherently uniform distribution of sealing pressure against the interior surface of a bottle neck.
It is still a further object of this invention to provide a stopper which utilizes compressed air to laterally expand the sides thereof into sealing engagement with the bottle neck.
It is a further object of this invention to provide a stopper which is simple to use, may be easily mann factured, and provides an effective seal for the bottle.
Other objects may be seen and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings.
In accordance with one embodiment of the invention, the stopper comprises a resiliently expansible hollow body adapted for insertion into the neck of the bottle. The body is closed at one end and open at the other, and a positive air displacement means is provided to effect selective movement of an additional charge of air into the relaxed but air-filled body so that the walls of the body may be forced radially and elastically outward by the pressure of the air developed within the body until the walls sealingly engage the neck of the bottle.
The air displacement means preferably includes a pair of elements, the first element being mounted in fixed position within the open end of the body and having a bore communicating with the interior of the body. The second element of the air displacement means is a plunger having a piston portion slidably and sealably mounted within the bore of the first or fixed element and movable to displace air from the bore thereof into the body when the plunger is moved from an elevated position downwardly toward a predetermined position relative to the first element. This downward displacement of air from the bore of the first element into the expansible hollow body provides the necessary internal pressure needed to eifect expansion of the side walls of the body into sealing engagement with the neck of the bottle.
Releasable locking means is provided for locking the two elements of the air displacement means in position to maintain the pressure within the body member. Tins locking means is preferably in the form of interengageable projecting formations on the aperture fixed element and plunger.
To accomplish the desired expansion of the resilient body, the lateral walls thereof should be made relatively thin, and it is preferred that selected axially spaced portions of these walls be made thin so that the expansion may be concentrated in these portions and so that successiveseals may be effected by the expansion of the body. It is also preferred that the exterior of the body be stepped in order to aid the sealing between the body and the bottle neck.
With reference to the drawings,
FIGURE 1 is a sectional elevation view of a bottle stopper constructed in accordance with the instant invention, showing the stopper positioned within the bottle neck and the plunger raised prior to expansion of the side walls of the stopper body;
FIG. 2 is a sectional elevation view of the stopper with the plunger lowered and the sides of the body expanded into sealing engagement with the bottle neck;
FIG. 3 is an exploded perspective view of the bottle stopper;
FIG. 4 is a sectional view taken along line 44 of FIG. 2 showing the elements 'of the air displacement means prior to engagement of the latching formations thereon; and
FIG. 5 is a sectional View similar to FIG. 4 but showing the elements with their latching formations interengaged.
With further reference to the drawings and, more particularly, to FIGS. 1 and 2 the bottle stopper 19 is adapted for insertion into the neck 11 of a bottle in order to close the bottle and seal the contents therewithin. Narrow neck bottles of this type are of well known construction and commonly used as convenient containers for beverages such as for wine, champagne or soft drinks.
The stopper constructed in accordance with this invention comprises a soft, elastic rubber or plastic plug or body 12, an air displacement means including a first element or insert 14 and a second element or plunger 16, and a metal clamping ring 18 which resiliently clamps the soft, elastic plug 12 to the relatively hard insert 14.
The plug or body 12 is closed at its bottom end 22 and it is open at its upper end 24. This plug or body is hollow and the lateral walls thereof are preferably constructed relatively thin so that they may be easily expanded by the increase of air pressure developed within the body as will be hereinafter. described. While the lateral walls may be uniformlythin, it is preferred that the thinning be concentrated in several spaced annular areas as indicated at 2d and 28 in order to concentrate the lateral expansion of the body or plug into two successive annular seals. The exterior of the plug is preferably tapered toward the closed end, and there may be provided a plurality of annular and angular steps 3% these also serving to facilitate the seal between the stopper body and the surrounding bottle neck 11 The insert 14 which functions as one part of the air displacement means is preferably constructed of hard plastic or rubber although, if desired, it may be constructed of metal. The insert 14 is provided with a central aperture 32, the lower or forward end of which is restricted or narrowed to form a substantial cylindrical bore 33 which is spaced from the upper end of the insert and the diameter of which is smaller than the other portions of the aperture 32. At the upper or rearward end of the insert 14 is a disk-like shoulder portion 34 which abuts and preferably laterally overextends the open end 24 of the body 12 to afford a grip for facilitating extraction of the stopper from the bottle.
The forward end or nose portion 36 of-the insert 14 is disposed within the open end 24 of the plug and preferably is provided with an outwardly extending shoulder 36a, which is adapted to engage a corresponding inwardly extending shoulder 38 on the interior of the plug 12 adjacent the open end thereof. The nose portion is preferably forwardly (downwardly) tapered to facilitate initial insertion into the open end of the plug. The metal chord-like latching projectionASa on. the insert.
the engaging shoulders 36a and 33, and thus the body 12 and insert 14 are locked in sealing relationship with one another.
The second element of the air displacement means is the plunger 16 which has a piston portion 40 at its lower or forward end, a knurled knob 42 at its upper end and and is either moving or has been moved to pressurize the plug. If desired and to facilitate the seal, a suitable lubricant may be provided between the piston portion 40 of .the plungerand the bore 33 of the insert. 7 It 'will'be noted that a downward pressure may be manually applied to the knob 42 to effect downward movement of thepiston portion 40 within the bore 33, and the air which has been entrapped within the bore 33 will be forcibly displaced therefrom into the hollow plug 7 or body 12 to effect expansion thereof as illustrated in FIG. 2. Since the lateral expansion of the side walls of the body 12 is preferably restricted to the selected thin annual areas 26 and 28 of the body, the amount of displaced air required to effect scaling is minimized.
.It maybe seen that the enlarged upper portion of the aperture 32 above bore 33 permits air to enter the aperture and thus there is. no resistance to the downward stroke of the plunger 16 until the piston portion 40 enters the bore 33. While this upper portion of the aperture 32 is thus enlarged relative to the bore 33, it need only be enlarged enough to facilitate entry thereinto of the plunger piston portion 40 and to permit free entry of air. This upper portion, however, may if desired, be sufliciently restricted to provide at least partial guidance for the plunger, especially when the latter has been raised as illustrated in FIG. 1.
Once the plunger has been lowered and the air charge 7 has been delivered into the hollow plug 12 to expand and effect a seal between the sides of the plug and the surrounding bottle neck, it'is'necessary to lock the plunger in its lowered position in order to maintain this internal pressure so that the sides of the plug will remain expanded and the seal will be retained. In order to accomplish this a flat'formation 48 extends partially across the aperture 32 at the upper or rearward end thereof, and a chord-like projecting portion 48a of this formation furtherrestricts this end of aperture 32.
The cylindriform shank '44 of the plunger is recessed in the area 50 except for a remaining tongue formation 52. The recess50 .isof sufficient depth and width to permit the initial insertion of the plunger portion 40 into the aperture 32 bya slight tilting insertive movement, and this recess of suflicient length to permit the desired restricted longitudinal movement of the plunger 16 withtrated in FIG. 2, latching tongue formation 52 within the recess on the plunger shank will be positioned below the The relative positions of the formations 48a and 52 are illustratedin FI, G. 4. At this point the plunger 16 may be I rotated slightly in the direction of the arrow in FIG. 4 so 5. In this rotated position, the plunger 16 is locked against'upward movement and the pressure within the a shank 44 connecting the knurled knob 42 and the piston portion 40. The piston portion 40 of the plunger 16 has.
In order to remove the stopper, the plunger 16 may be rotated in the reverse direction to disengage the tongue formation 52 in the recess on the shank thereof from the chord-like projecting portion 48a on the insert. Thereafter the pressure. of the air within the hollow plug12 will urge thepiston portion 40 of the plunger upwardly in the bore 33 until the air pressure in the body normalizes and the sides of the plug return to their relaxed position as illustrated in FIG. 1. The stopper may then be easily Withdrawn from the bottle neck.
While the foregoing exemplifies the preferred structure, itwill be readily apparent that a'number of modifications may be made in the structure without departing from the spirit of the invention. For example, instead of the interlocking formations 43 and 52, threads may be provided on on the insert and on the shank of the plunger in order to drive the plunger downwardly into the insert for displacement or" the air from the bore 33. Also, other latching arrangements may be readily apparent. In addition, the interconnection between the insert 14 and the bodyi12 may be accomplished in a manner other than that described and illustrated such as, for example, by adhesives or possibly even by a threaded arrangement. In addition, if desired, the number of annular recesses such as 26 and 28 may be increased or reduced, 'or if desired, the side walls of the body 12 may be made uniformly very thin although thisjis not preferred.
From the foregoing it may be seen that a novel stopper has been provided which will effect a reliable closure for a narrow necked bottle. The side walls of the stopper are expanded by compressed air in a novel manplug 12 is maintained so that the lateral sides of the body will remain in sealing engagement with the surrounding bottle neck.
