IMPERIAL

PATENT OFFICE.

The present closure for bottles and other vessels is like a bellows compressible, in its cylindrical part horizontally corrugated capsule marked, which, when pressed together, folds in such a way that these both protrude inwards as well as outwards over the previous diameter and against appropriately designed surfaces

ίο or the shoulders of the container press down in such a way that that they prevent the capsule from being pulled off. The capsule can be placed on the mouth of the vessel. placed on the outside or in a corresponding one designed recess can be used in the mouth. The wrinkles when you squeeze the capsule go in the way in front of you that the capsule wall after more or less numerous places is bent inwards and outwards in other places. With an external overarching The inwardly bent parts of the capsule are what cause them to adhere on the appropriately designed neck or edge of the vessel, while with inserted capsules

the outwardly bent parts provide the necessary support.

A seal made of a suitable material can be placed between the closure capsule and the vessel. cork, for example.

In the drawing, in Fig. 1, the neck part of a bottle is in vertical section and further the closure member is shown in elevation prior to its attachment to the bottle.

Fig. 2 shows in vertical section the

Bottle with the closure attached to it, which is shown in section.

Figure 3 is a vertical section through another shape of bottle and an elevation the embodiment of the closure suitable for this purpose.

Fig. 4 shows in vertical section the bottle with the closure attached.

In the embodiment shown in FIGS is on the inner wall of the bottle neck 1 from the mouth a downwardly widening recess is provided, which is used to receive the closure part serves. The paragraph 2 prevents the downward movement of the closure part, while the conical recess allows the capsule to be pulled out after compression prevented.

The entire closure part consists of a cylindrical, with a number of horizontal Shafts 5 provided capsule 4 and from an eventual, directly attached to it sealing washer 7, which after pressing on the horizontal surface 2 ensures the tight seal. '

Preferably, the closure capsule is made of aluminum, which for the present Purpose seems particularly suitable because of its lightness and flexibility. Of course, any one can also be other suitable material is used, which has sufficient flexibility, to be pressed firmly and easily into the seat provided on the bottle neck.

Claims (3)

To effect the closure, the capsule is so in the bottle neck or the like. introduced that the sealing washer 7 rests on the extension 2. Then through any suitable means compresses the cylindrical part of the closure cap so as to that the space above paragraph 2 in the bottle mouth or the like is completely filled, as in FIG. 2 shows. The cap 4 is then flush with the upper edge of the bottle, but could if desired can also be pressed further into the bottle. In the illustrated in Fig. 3 and 4, the outer rim of the bottle mouth is seen having a tapered bottom is conical according recess \ ^r, so that the right dare paragraph 9 and the conical surface 10 is formed. The closure body here consists of a capsule of the same type as in FIGS. 1 and 2, but here the sealing disk 14 is inserted into the same. In order to attach such a closure, the closure capsule is so pushed over the mouth of the vessel that the lower edge of the corrugated cylindrical Capsule part rests on paragraph 9. If now the capsule through a suitable device is compressed, the sealing washer 14 is on the bottle mouth pressed and the folded part of the capsule firmly against the conical surface 10 of the recess printed, creating a tight connection between the cap and the bottle is created, as shown in FIG. 4. With the above-identified closures, bottle openings or the like can be used. very quickly when using a to compress the cylindrical part of the The capsule must be closed with sufficient pressure, taking into account the conditions provided in this part Waves make it easier to compress. P Λ T E N T - A N S P R Ü C H E: ι. Closure for bottles and other vessels with a sealing washer or -ring provided capsule, characterized in that the cylindrical part of the capsule is horizontally corrugated in such a way that that it can be pressed together like a bellows by pressing it onto the mouth of the vessel and, as a result of the resulting, wrinkles protruding inwards and outwards beyond the previous diameter against appropriately designed surfaces and approaches of the vessel so firmly that the capsule cannot be withdrawn. 2. Closure for bottles and other vessels according to claim 1, characterized in that that the vessel mouth inside with a downwardly widening recess (3) with lower horizontal surface (2) covered with a seal (7) is provided in such a way that the capsule is in the recess (3) can be used and after being compressed with the resulting folds against the conical surface firmly attached so that it cannot be pulled out again can be and together with the seal (7) results in a tight seal. 3. Closure for bottles and vessels according to claim 1, characterized in that that the vessel mouth is outside with a conically narrowing constriction (10) with a lower horizontal constriction Surface (9) is provided in such a way that the provided with an inserted seal (14) Capsule can be placed on the horizontal surface (9) and compressed so that the folds that form be pressed against the conical surface of the constriction and the capsule on the Hold on to the mouth of the vessel. 1 sheet of drawings.
