Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a lift lever crown cap system and method and more particularly pertains to forming a pour through top opening in a crown cap crimped onto a bottle, such forming of an opening being done in a safe, ecological, convenient and economical manner.
2. Description of the Prior Art
The use of closure systems of known designs and configurations is known in the prior art. More specifically, closure systems of known designs and configurations previously devised and utilized for the purpose of closing containers through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 6,109,465 issued Aug. 29, 2000 to Henning relates to a Tamper Evident Closure System. U.S. Patent Application Publication Number 2003/0057174 by Folchini relates to a Tamper Proof Closure for containers of Liquids. Lastly, U.S. Patent Application Publication Number 2007/0181526 by Frishman relates to an Easy-Pull Bottle Cap.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a lift lever crown cap system that allows for forming a pour through top opening in a crown cap crimped onto a bottle, such forming of an opening being done in a safe, ecological, convenient and economical manner.
In this respect, the lift lever crown cap system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of forming a pour through top opening in a crown cap crimped onto a bottle, such forming of an opening being done in a safe, ecological, convenient and economical manner.
Therefore, it can be appreciated that there exists a continuing need for a new and improved lift lever crown cap system which can be used for forming a pour through top opening in a crown cap crimped onto a bottle, such forming of an opening being done in a safe, ecological, convenient and economical manner. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of closure systems of known designs and configurations now present in the prior art, the present invention provides an improved lift lever crown cap system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved lift lever crown cap system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a lift lever crown cap system. First provided is a bottle for containing a liquid. The bottle has a generally cylindrical body. The bottle has an open top. The open top has a circular lip. The bottle has an axially spaced, outwardly extending projection. The lip is provided above the projection. The lip is provided in a horizontal plane at an elevation above a plane containing the outwardly extending projection. The bottle is fabricated of an essentially non-corrosive material. The non-corrosive material is selected from the class of essentially non-corrosive materials including glass, plastic, coated aluminum, steel and paper.
A crown cap is provided. The crown cap is sealingly coupled to the bottle. The crown cap has a circular central region. The crown cap has a downwardly extending side wall. The side wall is provided in a frusto-conical configuration. The side wall has an inwardly scrolled lower edge forming a continuous, inwardly extending annular ledge. The central region of the crown cap radially terminates in a downwardly extending V-shaped projection. The crown cap has an upwardly extending, inverted U-shaped projection. The U-shaped projection is provided between the V-shaped projection and the side wall. The crown cap is fabricated of a non-corrosive coated aluminum.
The crown cap is positioned over the top of the bottle. The inverted U-shaped projection is located above the lip of the bottle. The V-shaped projection is located radially inward of the top of the bottle. The side wall of the crown cap is crimped. The ledge of the crown cap is provided beneath and in continuous contact with the outwardly extending projection of the bottle. In this manner a tamper evident-secure lock band is provided. Further in this manner the body strength of the bottle is increased and evidence of tampering is provided.
The crown cap is adapted to be inverted prior to being crimped and coupled to the bottle. The space between the V-shaped projection and the side wall forms an annular trough. An adhesive is provided in the trough. The adhesive is a hot melt adhesive chosen from the class of adhesives including liquid flow-in and extrusion sealants. The adhesive is a plastic or rubber, natural or synthetic, or blends thereof. The adhesive is adapted to form a seal between the bottle and the crown cap.
