  1. 1
    I claim:1. A device for tapping pressurized Equid containers comprising handle means, apertured piercing means carried by said handle means adaptable for perforating the cover of a container and for discharging the Equid contained therein therethrough, cover gripping means carried by said handle means, said cover gripping means includ50 ing a prong reduced to the form of a narrow tooth located on a straight fine extending from the apertured piercing means in the longitudinal direction of said handle means, and serving as a fulcrum for effecting perforation of the cover by said piercing means in response to urging of said piercing means and of said gripping means by said handle means towards the top and the bottom parts, respectively, of the cover.
  2. 2
    A device for tapping a pressurized liquid container comprising handle means, apertured piercing means carried by said handle means adaptable for perforating the cover of the container and for discharging the liquid contained therein therethrough, cover gripping means carried by said handle means, said cover gripping means includes ing a prong reduced to the form of a narrow tooth located on a straight line extending from the apertured piercing means in the longitudinal direction of said handle means, and serving as a fulcrum for effecting perforation of the cover by said piercing means in response to 70 urging of said handle means towards the top and the bottom parts, of the cover, and means on said handle means for positionally adjusting said cover gripping means The present invention relates to a device enabling . a gas containing liquid to be tapped under pressure from a bottle or a can, for instance beer, giving it the well known characteristics of beer tapped under pressure from a cask, by formation of a dense and lasting froth on the top of the beer in the glass avoiding a premature discharge of the carbonic acid from the beer. ..,. According to the present invention, the device includes a trocar or bored punch used to pierce the cap of the bottle or top of the can, and means such as a lever, used to force the trocar through the cap or the can top to pierce it so as to let the liquid contained therein squirt under pressure through the open bore of the trocar into a glass or other container. In order to avoid pressure leakage around the neck ot the trocar, the latter is provided with a compressive material washer, forming a leakproof joint in cooperation with the periphery of the hole pierced in the bottle cap or in the can. . Further, in order to perform the fimction_of_a bottle opener of removing th- ------ --. -- certain quantity of Equid under pressure through the trocar bore, the lever or other means used to force the trocar through the cap is preferably provided with an element such as a prong which grips under the^edge, oftine cap so as to first give a f--------— - the cap with the trocar and then remove the cap from the bottle. . Tn one embodiment of the invention the device comprises a pah of punching pEers a jaw of which carries the trocar and the other the prong, so that when the pliers are closed after engagement of the prong underneath the edge of the cap, the trocar pierces the bottle cap and after squirting of the Equid through the trocar bore, the cap of the bottle can be removed by a shght upwards movement of the pliers. According to a further and simpler embodiment of the invention, the trocar and the prong are both carried by one and the same lever which is used Eke an ordinary bottle opener, but in two steps, the first step being to force the trocar through the cap and the second step to remove the cap from the bottle. The accompanying drawing shows by way of examples two embodiments of the present invention. Figure 1 shows a side view partly sectioned of a pair of punching pliers embodying the invention, and _ Figure 2 shows a side view of a device according to the invention in the form of a bottle opener. The punching pliers (Fig. 1) comprise two handles 1 and 2, with jaws 1' and 2', pivoted at 3 and normally pushed apart by a spring blade 4. A trocar 5 is rigidly mounted on the jaw 1. The bore 5' of the trocar passes through the jaw 1' and the trocar carries a washer 6, for instance made of rubber, so placed as to cooperate with the edge of the hole pierced by the trocar in the bottle cap 7 thereby to provide a fluid tight joint so that the Equid under pressure squirts solely through the passage 5'. fulcrum to the device for piercing 40 various changes and modifications may be made 2,839.221 correlative to the diameter of the container cover to be tapped.
  3. 5
    A device for tapping a pressurized liquid container comprising handle means, an apertured piercing member 15 carried by said handle means, a prong carried by said handle means in the same vertical plane as said piercing member, said prong being adapted to engage the peripheral underside of the container cover at a single point of contact, said piercing member and prong coacting to 20 effect perforation of the cover in response to an initial urging of said handle means and to effect removal of the cover in response to additional urging of said handle means, a resilient washer arranged on said apertured member, and coacting serrated means on said handle means for positionally adjusting said prong correlative to the dimensions of the container cover to be tapped.
