BOTTLE CAP Filed Feb 27, 1945 Patenied July 8, 1947 BOTTLE CAP Philip G. Coleman, Chattanooga, Tenn., assignor of one-half to Robert Troxel, Cincinnati, Ohio Application February 27, 1945, Serial No. 579,962

9 Claims.

My invention relates toimprovements in bottle caps and has to do, more particularly, with a bottle cap of the type that will be automatically destroyed by any attempt to remove it from the bottle.

In marketing whiskey and other spirituous liquors, it is desirable to provide a closure for the bottle which may be quickly and easily applied thereto but will be automatically destroyed by any attempt to remove the closure. The internal revenue stamp, and Various seals, are often applied over the closure and around the neck of the bottie and, thus, the destruction of the closure will indicate to the buyer that the contents of the bottle may have been tampered with since it left the distillery, at which the closure was first applied. The principal object of my invention, therefore, is to provide an improved closure for a bottle, which will be automatically destroyed by any attempt to remove the closure.

A further object of my invention is to provide a bottle closure comprising a plastic screw cap and means automatically eifective to burst the cap upon any attempt to unscrew it from the bottle.

A further object of my invention is to provide a closure that will be automatically destroyed by any attempt to remove it from the bottle, but which will leave behind a portion that may be conveniently used as a temporary stopper for the bottle.

Further objects, and objects relating to details of construction and economies of operation, will definitely appear from the detailed description to follow. In one instance, I have accomplished the objects of my invention by the devices and means set forth in the following specification. My invention is clearly defined and pointed out in the appended claims. A structure, constituting a preferred embodiment of my invention, is illustrated in the accompanying drawings, forming a part of this specification, in which Fig. 1 is an exploded perspective viewshowing the neck of a bottle and a bottle cap, constructed in accordance with my invention.

Fig. 2 is a perspective view of the neck of a bottle with the cap applied thereto.

Fig. 3 is a horizontal, sectional View through the cap and bottle neck, taken on the line 33 of Fig. 4.

Fig. 4 is a vertical, sectional view through the bottle cap and the neck of the bottle, taken on the line 4-4 of Fig. 3, and

Fig. 5 is a fragmentary, sectional View, corresponding to a part of Fig. 3, but showing the cap in such relation to the neck of the bottle that one of the tongues is flexed to one side to permit it to pass a cam shoulder on the bottle neck.

In the drawings, the same reference numerals refer to the same parts throughout the several views and the sectional views are taken looking in the direction or" the arrows at the ends of the section lines.

In general, my invention comprises a closure for a bottle, rotatable on the neck thereof, and. which includes a plastic cap having a top and an integral skirt surrounding the neck of the bottle, and cooperative means on the bottle neck and the cap for exerting a bursting pressure on the skirt, when the cap is rotated in one direction. The skirt of the cap is provided, preferably, with a plurality of longitudinal weakening grooves parallel to the axis of rotation of the cap, and the cooperating means are such that the bursting pressure is applied to the skirt at points in line with these weakening grooves. I prefer to provide the neck of the bottle, in a zone below the external screw thread thereon, with a plurality of cam shoulders, each of which has an inclined cam face tangent to the cylindrical portion of the bottle neck and a face which extends radially of the bottle neck, and to provide a plastic cap comprising a top and a skirt that surrounds the bottle neck and is provided with an internal screw thread, for cooperation with the external screw thread on the neck, and a plurality of integral tongues projecting inwardly from the cap skirt and normally lying tangentto a cylinder coaxial with said skirt. These tongues are located on the cap below the screw thread, so that, when the cap is screwed on the bottle neck, these inwardly-projecting tongues will cooperate with the cam shoulders. The tongues are preferably located on the skirt at points adjacent the longitudinal weakening grooves thereof. When one attempts to unscrew the cap, the radial shoulders on the bottle neck will engage the ends oithese tongues and press them lengthwise, thus exerting bursting pressure upon the skirt at the points where it is weakened by the longitudinal grooves. A circumferential weakening groove may be provided at the junction of the top of the cap with the skirt and, when the skirt of the cap is burst, the top, with the cork sealing disc secured thereto, may be used as a temporary stopper for the bottle.

Referring to the numbered parts of the drawings, the bottle ID has a cylindrical neck portion [I provided with an external screw thread l2. In the Zone below the screw thread l2, the cylin- 3 drical neck portion is provided with four cam shoulders symmetrically arranged thereon, each of which has an inclined cam face l3, which extends tangentially to the cylindrical neck I l, and a face Hi, which extends radially of said neck.

The cap is made of any suitable plastic and comprises a top l and a cylindrical skirt l6.

ject inwardly of the skirt and normally lie tangent to a cylinder coaxial with the skirt. They are located on the skirt below the screw thread [9 so that, when the cap is screwed home on the bottle neck, the tongues 20 will engage the cam shoulders having the sloping faces l3 and the abrupt faces I4. A sealing disc 2!, of cork or cork composition, is cemented to the inner surface of the top 15 of the cap and provided with a hemispherical portion 22, fitting within the mouth of the bottle and serving as a stopper therefor.

When the bottle has been filled, the cap is screwed onto the neck of the bottle until the sealing disc 2| engages the lip thereof, and the portion 22 seats within the mouth of the bottle,

as shown in Fig. 4. As the bottle cap is screwed up,

the tongues 29 engage and slide over the cam faces I3 of the cam shoulders, bein flexed thereby as shown in Fig. 5. The tongues 29 snap over these shoulders successively and, when the bottle cap has been screwed up, the tongues will occupy the positions, shown in Fig. 3, with reference to the radial faces [4 of the cam shoulders. If, now, one attempts to unscrew the cap, this will cause the tongues 20 to press endwise against the radial faces 14 of the cam shoulders and, as a result thereof, a bursting pressure will be transmitted to the skirt H5, at the points where that skirt is weakened by the longitudinal grooves H8. The result will be to burst the skirt of the cap along the. grooves l8. The portions of the skirt between the grooves I8 may be broken away, leaving the top l5 and the cork sealing disc, which may be used as a temporary stopper for the bottle.

-I am aware that the bottle closur shown and described herein may be varied considerably without departing from the spirit of my invention, and, therefore, I claim my invention broad- 1y, as indicated by the appended claims.

Having thus described my invention, what I claim as new anduseful, and desire to secure by Letters Patent, is:

1. The combination of a bottle having a neck, a closurefor the bottle rotatable en the neck and including a plastic cap having a top and an integral skirt surrounding the neck, said skirt having a plurality of longitudinal weakening grooves therein parallel to the axis of rotation of the cap and extending from said top to the bottom of said skirt, and means for exerting a bursting pressure on said skirt at points adjacent said weakening grooves, to rupture said grooves and burst the skirt of said cap to disintegrate said cap, upon rotating the cap, in one direction, with respect to said neck.
