| (54) | STRUCTURAL ARRANGEMENT FOR A BOTTLE CAP |
| (57) The present utility model relates to a structural arrangement for a bottle cap, belonging
to the technical field of packaging accessories in general, more particularly to a
cap for beverage bottles, such as beer, water, soft drinks, or any other drink or
product for which the bottle is used as a packaging container, producing convenient,
safe and functional results which are very advantageous. The innovation comprises
a cap (10) to which an opening device (30) is coupled by a clip in the central top
part. The cap (10) has a breaking zone (101) and a central hole (102) for coupling
the clip (20) which links the cap (10) to the cross-shaped opening device (30) which
forms four levers (302) with protruding projections (303) on the top surface and with
a piercing "point/tooth" (304) on the underside of each lever (302), which pierces
the breaking zone (101), allowing the inner pressure to escape and thus making it
easier to remove the cap (10) with the lever formed at the opposite end. |
[0001] The present utility model patent refers to a constructive arrangement introduced in a bottle cap belonging to the technical sector of packaging accessories in general, more particularly a bottle cap for beverages such as beer, water and soft drinks or any other beverage that uses the bottle as packaging conditioner, through which very advantageous practical, safe and functional results are obtained.
STATE OF THE ART
[0002] According to www.papodebar.com, there by the 1880s, carbonated beverages began to become super popular in establishments, but it was kind of tricky to get them home. Generally, the bottles were sealed with corks or ceramic, wood and metal caps, but could not handle carbon dioxide efficiently. And worse, if they came in contact with the liquid, they could even make it toxic. Until William Painter solved the problem, inventing in 1891, the crown cap, with a disc of cork in that avoided the contact of the drink with the metal (nowadays, is used plastic). The cap, with its corrugated edge, was the perfect solution to seal, without leaks, the bottles with carbonated liquid. After inventing the crown cap, in 1894, William Painter invented his faithful partner: the opener.
[0003] For a long time, the crown cap was used in the company of the indispensable opener, until with the advent of disposable bottles of beers called "long neck", the traditional caps were replaced by the new caps that allowed to be threaded in the mouths of the bottles, thus eliminating the need to use the opener. However, in addition to the normal bottles, which have continued to use the traditional caps, a new ecological appeal has given way to the new returnable bottles of beers and the old bottles of soda, which use the old caps and its indispensable opener, which often becomes an inconvenience in the use of such packaging.
[0004] Thus, to make the use of disposable containers more comprehensible without the inconvenience of carrying an opener, the present innovation was developed, which through the constructive arrangement of the cap and its constructive variants allows the opening of the bottles with a coupled cap to an opening device allowing it to be opened.

[0022] With the constructive arrangement introduced into the bottle cap thus obtained, it offers the following advantages over its known congeners:
- Encourages the use of returnable bottles without the need for the opener;
- Ease, practicality and immediacy in opening the cap, especially disposable bottles of beers called "long neck";
- Greater safety and speed since the device is already in the correct position of use aiming the instant opening; and
- Allows the use of recyclable materials in the cap.
