The present invention relates to an opener for uncapping a bottle of beer, soft drink or other liquid container that has been sealed with a crown cap.
A wide variety of bottle openers is known in the art. Low, in U.S. Pat. Nos. 1,214,802 and 2,155,947 describes variations of a bottle opener which can be operated using one hand. However, Low's one-handed design requires that the opener be placed in position upon the bottle cap before the fingers of the same hand are able to reach and grasp the bottle neck. This drawback results in the propensity to tip or tumble the bottle while engaging the opener. It also requires that the unopened bottle is supported by a table or other structure while the opener is being engaged with the bottle cap. Kichijyo, in U.S. Pat. No. 4,414,866 describes a one-handed bottle opener composed of various levers and springs. This device is operated by pushing down on the opener, or by gripping a lever. Other one-handed bottle openers are similarly complicated, involving linkages and other moving parts, resulting in high cost of manufacturing and propensity for breaking. These include Ranseen U.S. Pat. No. 2,440,485, Chapman U.S. Pat. No. 2,961,902, Sprich U.S. Pat. No. 2,593,358, Talbot U.S. Pat. No. 2,551,511, Davis U.S. Pat. No. 4,702,130, Salcedo U.S. Pat. No. 4,852,432.
These one-handed openers all require a surface, such as a table, supporting the bottle as the opener is being placed into its operative position upon the bottle cap. Related art also includes various glove and strap-on type bottle openers such as, Erwin U.S. Pat. No. 5,133,233, Kondos U.S. Pat. No. 5,261,299, Sasso U.S. Pat. No. 6,761,088.
It is an objective of this invention to provide a new bottle opener which incorporates many of the advantages of related art, while simultaneously overcoming the disadvantages and offering new advantages.
The opener is preferably made from one piece of metal, or other suitable material such as plastic. The opener can also be made from a combination of suitable materials. It has no moving parts and no adjustments, such as straps. This simplicity allows for very low cost of manufacturing, similar to traditional two-handed bottle openers (one hand holding the opener and the other holding the bottle) made from one piece of material. However, the present invention departs significantly from related art by allowing the user to grasp the bottle first, and then engage the opener. In related art, one-handed openers require a structure underneath the bottle, such as a table, to support the bottle while the opener is engaged. In the present invention the opener can be manipulated using only the thumb and one finger. Engagement of the opener with the bottle cap can be accomplished while holding the bottle between the remaining unused fingers and palm of the hand without a supporting surface, such as a table, beneath the bottle. This significant departure from related art provides novel convenience for individuals, such as a bartender carrying the bottle while walking, or for those who have the use of only one hand.
