MEANS FOR CLQSENG REOEPTACLE'S.
Specification of Letters Patent. Application filed November 28, 1906- Serial No; 345,531. v
Patented May 7, 1907.
To an whom it may concern:
Be it known that I, ERNEST SAUTTER, a citizen of the Confederation of Switzerland, residing in Paris, in the Republic of France, and whose post-office address is 56 Rue de La Victoire, Paris, have invented a new and useful Improvement in Means for Closing Receptacles, which improvement is fully set forth in the following specification.
This invention has for its object an arrangement for closing any type of. rece tacles, bottles, flagons, jars, pots and the ike, and particularly conical drinking glasses having a smooth edge.
The method of closing is based on the reaction of two conical surfaces pressing against one another (under the influence of an elastic force) so that the large end of theone tends to approach the small end of the other. In order to effect this, the present arrangement ,consists of a metal capsule, with waved or fjborrugated sides, in the bottom of which is ijan elastic washer, and on which a smooth cylindrical metal locking ring curved at both its edges or at its upper edge only, is applied by clamping or otherwise. The Waves or corrugations of the sides begin a short distance from the top and become larger toward the edge, so as to present to the exterior a substantially conical surface, the inside being cylindrical. It will be seen that if a capsule of this kind withan elastic washer and a look ing ring is placed. on the conical mouth of a receptacle to be closed, and pressure is exerted on the capsule, the locking ring being put over it, the corrugated walls of this capsule will be bent inward and be pressed into close contact with the mouth of the receptacle, the outward surface thus becoming cylin drical & the inner surface will be made conical by the mouth of the receptacle. The action of the joint and the elasticity of the/corrugations of the capsule keep the receptacle hermetically closed. The downward movement of the locking ring is stopped by its u per curved edge. The locking ring can fie placed in position by any other suitable means such as by a strap capable of deforming the capsule in the same way. The lockingring is prevented from coming off, either by curving in the lower edge against the lower edge of the capsule, or by any appropriate means. This curving in of the edge can be effected either by the natural elasticity of the metal of the locking ring or by giving it a hooked shape, or by the partial or plicable to recep acles having a cover of their own. In this case the capsule is cutaway and is placed direct on the cover and the elastic packing is placedJbetween the cover and the receptacle itself.
In the drawings which show examples of carrying out the invention: Figure 1 shows separately in perspective thedifferent elements used in closing. Fig. 2v is a section on a larger scale of the elements in position ready for closing. Fig. 3 is a similar sectionwith the curved ed e of the locking ring under the capsule. ig. 4 is a similar section showing the curved edge pressed farther in. Figs, 5, 6, 7 are views of the capsule showing different forms which can be used for makingthe corrugations or folds of the capsule. Figs. 8, 9 and 10 are sectional views of modified forms of closures.
The diflerentelements of the closure which are placed on the conical mouth'a of there. ceptacle to be closed, are the elastic washer b forming the joint, the capsule 0 whose sides have corrugations d, which begin a short distance from the top and the locking ring' e which looks the capsule.
In the case where the locking ring is put in' position by clamping, the washer b is first placed in the capsule c, and when the receptacle is about to be closed, the different elements are in the position shown in Fig. 2. The locking ring e having'its ends fastened together by an ordinary hooked joint, such as is shown and having at its lower end a curved edge f passes freely as far as the osition shown in the figure. In order. to e ect the closing it is forced into place in such a way as to turn under the corrugations d of the capsule which press firmly against the mouth of the receptacle, thus causing a tendency of the capsule to come close against theedge of the opening, that is to say to squeeze the joint and to make the closing hermetical. In this movement the locking ring can be guided in order to avoid deforming it. At the end of its travel, the end g of the curved lower edge f of the locking ring hooks under the corrugations d of the ca sule, owing to its elasticity, as is shown in ig. 3, and it is I propriate opening of the capsule; in addition,
In the case of an annular washer contact beabove,
the mouth of the receptacle, in combination thus rendered impossible to open it without opening out the curved edge, and so spoiling the locking ring. The closure obtained cannot thus be tampered with.
The curving in of .the corrugations by the end 9 of the curved edge fol the locking ring can be made more complete by acting on this curved edge during the operation of closing by deforming it and making it pass farther under the corrugations of the capsule as is shown in 4.
The folds of the capsules can take different forms without modifying any of the other parts described. The forms shown in Figs. 5 and 6 or similar forms will be used when great rigidity is wanted, for closing thick and strong re'ceptacles' The form shown in Fig. 7 and similar forms will however be adopted when greater pliability is required as for example for closing thin glasses.
An annular washer can be placed in an apm order to improve its appearance, the upper end of the capsule can have a groove on which the edge of'the locking ring will lie.
tween the capsule and the matter contained in the receptacle can be avoided by fastening on to the lower face of the annular washer a diski of tin or other suitable substance.
In the case of closing a receptacle having its own cover the annular washer is placed between the receptacle and its cover and pressed by means of a capsule having its center cut away and with corrugated or wavy sides, held by the arrangement described Having now particularlydescribed and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:
1. An improved closure for receptacles, comprising a. capsule arranged to embrace with an annular band surrounding the capsule, the band having an inturned lower edge to snap underthe lower edge of the capsule.
2. An improved closure for receptacles, comprising in combination, a receptacle having smooth sides a eapsule' with flaring corrugated walls arranged to embrace the mouth of the rece taele, and an annular band bean ing upon t e top of and surrounding the capsule and pressing inwardly upon the corrugations.
edge of the receptacle mouth within the cap sule, in combination with an annular hand surrounding the capsule, the band having an inturned lower edge to snap under the lower edge of the capsule.
5. An improved closure for receptacles, comprising a capsule with expansible walls arranged to embrace the mouth of the reccptacle and provided'with spaced inward 'eX- tensions, and anelastic washer resting upon the edge of the receptacle mouth within the capsule, in combination with an annular band surrounding the capsule and bearing inwardly by means of the inward extensions upon the receptacle, the band having an inturned lower edge to snap under the lower edge of the capsule.
6. The combination, with a receptacle having smooth upwardly flaring sides, of a capsule with corrugated walls arrangedto embrace the men th of-the receptacle, a washer resting upon the edge of the receptacle mouth within the capsuleuand an annular band surrounding the capsule and bearing inwardly upon the corrugations.
7." The combination, with a receptacle having smooth upwardly flaring sides, of a capsule with corrugated walls. arranged to embrace the mouth of the receptacle, a washer resting upon the edge of the receptacle mouth within the capsule, and an annular band surrounding the capsule and bearing inwardly upon the corrugations, said handliaving an inturned lower edge to snap under the lower edge of the capsule.
In testimony whereof I have signed. this specification in'the presence of two subscribing witnesses.
