BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Jul s, rein.

To all whOm it may concern:

W. H. CLAY, a citizen of the United States, residing at State of Pennsyl- Improvements in Bottle-Closln'es, of which the following is a specification.

My invention relates to metallic caps for jars, etc., and particularly to means for locking and unlocking the closure.

The invention is illustrated in 01 f as applied to a mi k bottle in the accom panying drawing, wherein Figure 1 is-a central vertical section ofa jar with a cap in place thereon. Figs. 2 and 3 are side elevations at right angles to each other of a cap provided with an opening device, Fig. 4 being a plan view of the same. Fig. 5, shows an alternative form in which the locking flange is locked against opening. Fig. 6 illustrates the mode of cutiling the blank for this latter device, and Fig.

is a side elevation of the locking lugs in place.

In several patents heretofore granted to me I have shown a bottle cap which engages the glass by the edges of a slotted metal flange, so as not to depend upon friction for the hold. on the bottle, such caps also having the feature of maintaining a pressure by the strain of the metal itself rather than by the elasticity of the packing employed. As shown herein, I may provide a cap 8 with a paper packing 9 resting on the mouth of the bottle 10, the sides of the cap 11 being in loose circumferential contact with the bottle flange and the slotted and indented parts of the flange 12 directly engaging the glass by the edge of the metal. Properly proportioned the inwardly bowed portions 12 must be sprung outward in order to go over the bottle flange as pressure is applied and when such pressure is removed the arches 12 have a direct hold on the glass and are placed under a downward stress. As long as the parts are in position as shown in Fig. 1, it is evident that any pressure under the cap. pushing the arches 12 upward, also tends to force them inward andthcrefore locks the cap tighter. Meanwhile the seal is kept by the resiliency of the metal in the arches 12. If the generally conical shaped skirt formed by the series of inward arches 12 and the intervening connecting arches 13 be in, anywise expanded circumferentially,

the hold of the arches 12 may be loosened,

and only by such separating of this conical skirt can the cap be removed. My present improvement contemplates any means for expanding the conical skirt. For instance, I may provide the two lugs 1t and 15 turned up out of the metal of the skirt as shown in v Figs. 2, 3 and 4, so that by pushing one in one direction and one in the other, the skirt can be spread and the cap removed. This is easily done with the thumb and finger or any convenient tool for applying twisting movement tothe lugs. In this form of the cap, the application to the bottle is made by simple downward pressure, snapping the cap over the bottle-flange and to better its hold on the bottle, I may provide the rib 16 shown in Fig. 2, or other stiifening means.

Generally, there should be only enough metal on the outward arches 1.3, to safely hold the flanged skirt and stand the pressure necessary where the cap is applied by aring engagin the arches 13 as in my previous Patent o. 860,964, July 23, 1907. Thepresent cap however, is easily applied by. 1

and pressure and can be used over again indefinitely, the metal not being permanently distorted.

In some instances itis desirable to ,absolutely lock the cap on the bottle, and in such case the opening lugs may be made as shown in Figs. 5 to 7. The punched out portions 17, 18, are turned up at right angles so that the lug 19 engages the side of the lug 18, thus preventing a mere pressure on the sides of parts 17,-1.8, from releasing the cap. The release is accomplished by a slight vertical displacement of the lugs 18and17 either with the fingers or by inserting a sharp tool in the small slot (20). As shown in Fig. 7 a. bit of sealing wax may be applied at X so that the bottle cannot be. opened without breaking the seal. It will be seen that this provides ready means for sealing certified milk, etc. The same end can be accomplished with the form of lug shown in Fig. 2 as by sealing the lugs 14, 15, together. The cap may be attached to the bottle by a wire through any opening therein and around the bottle as through Q the lug 15.

Theadvantage of a bottle or jar cap which may be repeatedly applied by merely springordinary blows and not disturbed by inside pressure in the bottle; which keeps its seal by the resiliency of the metal itself rather than by the packing which may be removed by hand, and which may be at the same time sealed without interfering with the hancl opening feature, all how from the peculiar construction shown and the many advantages oi the device will be apparent to those familiar with the art.

Having thus described my inyention and illustrated its use, What I claim is the following 1. A bottle sealing cup having a generally conical shaped flange with horizontally slotted portions engaging by their edges the flange of the bottle, and means for spread ing the said conical shaped flange to re lease the hold on the bottle.

'2. The combination with flanged-I lrottle mouth of'a metallic sealing cap comprising; a cover, a circumferential flange of general conical form slotted at intervals and the slotted portions bowed inwardly to engage the bottle flange on the eclge of the metal,

of a pair of lugs arranged on the cen' skirt and. adapted to circumferential1y spreac' the skirt, substantially as described.

3. A bottle sealing cap comprising a cover and a dependent flange having eircmnfen .26

loosening the grip of such arches comprising projections on the skirt of the cap adapt ed to be moved by hand, substantially as described.

In testimony whereof I have hereuntosigned my name in the presence of the two subscribed Witnesses.
