SEALING BOTTLES AND LIKE RECEPTACLES Fernando Casablancas, Sabadell, Spain Application August 26, 1936, Serial No. 98,032 In ‘Spain August 30, 1935 4 Claims. (Cl. 215-45) The present invention relates to closures for discs l5 and I6, connected together by rivets or sealing bottles and like receptacles, which are ' other suitable means, and the upper disc I5 is applied exteriorly on to the mouth of the bottle or the like and has for its chief object the pro vision of an improved stopper which will per mit of the sealing and unsealing the receptacle a great number of times, while always affording a perfect hermetic seal. The closure according to the invention com 10 prises essentially a metal cap inside which is disposed an elastic member having a number of in turn connected to a U-shaped member H, which projects upwards and traverses the up per part of the cap projecting to the outside. in In the extremities of this U-shaped member there is disposed a spindle or pin l8 serving as a pivot for an eccentric I9 connected to a lever 2|! and so disposed that upon actuation of the said lever the eccentric bears against ‘the upper part 10 of the cap I0, preferably through the interme diary of a washer 2|, and lowers the cap III in curved lugs, the said elastic member being com bined with an eccentric actuated from outside by relation to the elastic member l2, thus causing the lugs of the said elastic member to become means of a lever, whereby the elastic lugs en 15 gage a ?ange disposed exteriorly on the neck of locked by their engagement with the conical the bottle, a hermetic seal being obtained by the surface II and, consequently, to engage ?rmly interposition of a washer or disc of rubber 'or on the ?ange 22 of the neck of the bottle or other suitable elastic material between the said receptacle 23. Furthermore, in order to obtain hermetic seal member and the mouth of the bottle. The action of locking the curved lugs in order ing, there is disposed between the elastic mem 20 that they may engage on the ?ange oi the neck her and the mouth of the bottle a washer or disc 24 of rubber or other suitable elastic material, of the bottle is obtained by the special arrange ment of the outer cap of the closure, which has which is normally held in position in the stopper a conical portion ?tting on the curved part of by the same curvature of the elastic lugs. In the modi?cation shown in Figure 4, instead 25 the lugs, the whole being so arranged that upon actuation of the eccentric the elastic member of the full rubber disc 24 of Figures 1 and 2, is forced into the cap, the pressure of the conical there is employed a rubber washer 30 which in portion thereof thus bending and locking the lugs its central part bears a cup like piece 3| of of the elastic member. Subsequently, in order aluminium or other suitable material. This ar 30 to withdraw the closure from the bottle, it is rangement prevents the liquid in the bottle from touching the rubber, but in other respects su?icient to actuate the eccentric in the oppo site direction, whereupon the pressure acting on is fully equivalent to the arrangement of Fig the elastic lugs is relieved and the lugs leave the ?ange of the bottle. A form of construction of the closure accord 35 ing to the present invention is illustrated in the 40 20 25 30 » ure 1. Figure l is a sectional view of the closure in the position in which it is mounted on the bottle. The lever 20 actuating the eccentric may be of any desired form, preferably curved, as shown in the accompanying drawing in order that once the bottle is sealed this lever may ?t against the neck thereof without causing any obstruction. Moreover, in the said lever there is also pro Figure 2 is a section of the closure ?tted on a vided a recess 25 of suitable form, one of its edges accompanying drawing, in which: 15 26 being slightly bent over in order that the said recess may be used for opening the receptacles on an object of suitable dimensions and form or bottles sealed by the closure. Finally, this cap may be combined with an for placing on the market, and object of suitable form, for example that shown 4 Figure 4 shows a modi?cation. 45 The closure is constituted by a cap "I sub- ~ in Figure 3, which has the form of a small re stantially wider than the neck of the bottle and ceptacle, the upper part of which has the usual having intermediately of its height an inclined dimensions of the mouth of a bottle. This object serves for the presentation of the closure for sale portion ll constituting a conical surface. Inside this cap is disposed an elastic member in attractive form and may be so disposed that, 50 l2 having a number of curved lugs l3 disposed in addition, it may then be used as a tooth-pick in such a manner that when in their lower posi holder or for other purposes. tion the ?ange of the neck of the bottle may be I claim:— 1. A closure for a container having a ?anged freely introduced between the said lugs. 56 The elastic member I2 is held between two opening, comprising an elastic grasping member 55 bottle. Figure 3 is an exterior view of the closure ?tted 2 2,132,775 having an upper portion and depending lugs, a cap over said member having upwardly tapering side walls and an opening in the top, a rod ex tending from said member through the opening rod secured to said member and extending up wardly, a cap having an opening in. its upper wall to receive said rod and having side walls of a diameter to force said lugs to engage the in said cap, means for securing said rod to said member, and cam means at the free end of said ?ange 01' the container when the cap is posi tioned around said member, and a lever pivoted rod for urging the cap downwardly toward the member whereby the tapering side walls move the lugs ‘inwardly to engage the ?ange of the at the free end of said rod above the upper wall of said cap, said lever having a cam portion to work against the upper wall of the capwhen the lever is operated to draw the cap and mem-1 10 ber together and position the cap around the 10 container. 2. A closure for a container with a ?anged opening, comprising an elastic grasping member having an upper portion and depending lugs, a rod attached to said upper portion and extend ing upwardly therefrom, a cap having an opening in the top to receive said rod and having side walls at the bottom of greater diameter than said lugs and an upwardly tapering portion of less diameter than the lugs, and cam means piv oted to said rod above said cap adapted when operated to work on the upper side of said cap and force it downward upon said member where by the tapering portion of the side walls of the cap urge the lugs inwardly to engage the ?ange of the container. > 3. A closure for a container with a ?anged opening, comprising an elastic grasping member having an upper portion and depending lugs, a member. . 4'. A closure for a container having a ?anged opening, comprising an elastic grasping mem ber having a ?at upper portion and depending 15 incurved lugs, connected discs above and below said ?at upper portion, an upwardly extending rod secured to the disc above said portion, a cap over said member having in its upper wall an opening to receive said rod and having upwardly 20 tapering side walls, and cam means secured to the upper end of said rod above said cap adapted when operated to work on the upper wall of said cap to force it toward the member whereby the tapering side walls move the lugs inwardly to 25 engage the ?ange oi’ the container.
