| (54) | STRUCTURAL ARRANGEMENT APPLIED TO A BOTTLE CAP |
| (57) The present utility model related to a structural arrangement applied to a bottle
cap, belonging to the technical sector of general packaging accessories, and specifically
to a cap for bottles containing beverages, such as beer, water, soft drinks or any
other beverage that is packaged in a bottle, that provides very advantageous practical,
safe and functional results. The present utility model patent comprises a metal cap
(1) provided with an L-shaped lever/handle (2) in which the smaller segment (21) and
the extremity of the larger segment (22), which is close to the vertex, are attached
to the upper face and to the peripheral wall of the cap (1) by welding, gluing, pinning
or any other attachment means, the lightly grooved vertical larger segment (22) forming
the "handle" having a ring-pull (23) at the extremity of same. Optionally, according
to figures 1.6 and 1.8, the extremity of the larger segment (22), which is close to
the vertex, is formed around the peripheral wall of the cap (1), forming a corrugated
area with the same "relief/molded" system present in the cap (24). |
DISCLOSURE OF THE INVENTION
[0001] The present Utility Model Patent is directed to a structural arrangement applied to a bottle cap, pertaining to the technical sector of packaging accessories in general, more particularly a cap for bottles of beverages, such as beer, water and soft drink or any other beverage that uses the bottle as a packing container, through which advantageous practical, safe and functional results are attained.
STATE OF THE ART
[0002] In accordance with to www.papodebar com, in the 1880's, carbonated beverages started to become quite popular in bars, but it was quite complicated to take them home. Generally, the bottles have been sealed with corks or ceramic, wood and metal caps, but they could not retain the carbonic gas efficiently. Still worse, in the event they contacted the liquid, it could become toxic. Until William Painter solved the problem by inventing in 1891, the crown cap provided with a cork disk inside same that prevented the beverage from contacting the metal (plastics are used nowadays for such purpose). The cap, with its corrugated edge, was the perfect solution for sealing, without any leak, the bottles containing carbonated liquids. After inventing the crown cap in 1894, William Painter invented its faithful partner the can opener.
[0003] The crown cap has been used for a long time in the company of the indispensable can opener, until the advent of the so-called "long neck" disposable beer bottles, the traditional caps have been replaced by the new caps that can be threaded to the mouths of the bottles, thus eliminating the need to use the can opener. However, in addition to the regular bottles that kept on using the traditional cap a new ecological appeal is paving the way to new returnable beer bottles and the old soft drink bottles, that use old caps and the indispensable can opener, which is many times inconvenient when using such containers.
[0004] Thus, in order to extend the use of disposable container, without the inconvenience of carrying a can opener, the present invention has developed a structural arrangement of a bottle cap and its constructive variants, thus making it possible to open bottles having a cap provided with a lever that allows same to be opened.

[0006] In accordance with Figures 1.1 to 1.8, the present utility model patent comprises a metal cap (1), provided with an L-shaped lever/handle (2), whose smaller segment (21) and the end of the larger segment (22) are close to the vertex, attached to the upper face and the peripheral wall of the cap (1) by weld, glue, pin or any other attachment means, said larger segment (22) being vertically positioned and slightly grooved for the "handle" having a slit (23) at the end thereof. Optionally, in accordance with Figures 1.6 and 1.8, the end of the larger segment (22), close to the vertex, is arranged following the peripheral wall of the cap (1), forming a corrugated region with the same relief/flange system existing in the cap (24).
[0007] In accordance with Figures 2.1 and 2.2, in a first constructive variant, the lever for the handle (2), can be arranged at angles, forming a vertical segment (221) from the vertex that ends in an oblique segment (222) that, in turn, ends in a vertical segment (223).
[0008] In accordance with Figures 3.1 to 3.5, in a second constructive variant, the cap (1) and the lever (2) is made as a single body (12), said lever (2) extending from the edge of the peripheral wall of the cap (1).
[0009] In accordance with Figures 4.1 to 4.6, in a third constructive variant, the lever (2), is provided at the end of the smaller segment (21) with an inclination that forms a perforating "tip/tooth" (211), which, at the time the cap (1) is opened, perforates the upper face thereof, releasing the inner pressure and thus making it easy to release the respective cap (1) with the aid of the lever (2). See the perforating "tip/tooth" already inserted into the cap that removes the pressure/carbonic gas.
[0010] In accordance with Figures 5.1 and 5.7, in a fourth constructive variant, the lever/handle (2) is integral with the cap at the upper end thereof and provided with two hooks in the lower portion of the cap (25) at the edge of the bottle and on which the cap (1) is attached/fixed, said cap (1) being or not already attached to the lever (2). The function of the hooks (25) is to "force" and expel the bottle cap.
[0011] In accordance with Figures 6.1 to 6.8, in a fifth constructive variant, the cap (1) and the lever/handle (2) is made of plastic, polycarbonate, fiber/glass and molded in a single part, and said material may be opaque or transparent.
[0012] With the structural arrangement applied to a bottle cap thus obtained, it offers the following advantages in relation to its equivalents known so far:
- it stimulates the use of returnable bottles without the need to use the can opener;
- an easy, practical and fast way to open the cap, mainly of the so-called "long neck" disposable beer bottles;
- more safety and speed since the lever is already in the correct position of the "handle" aiming at the immediate opening;
- it makes it possible to use recycled materials in the cap.
