Problems solved by technology

[0009] Another disadvantage of this known solution arises from the fact that the cans are stacked such that the can lids on their seals accommodate the usually double-crimped lower edge of the tubular body of the can next to it

Embodiment Construction

[0022] According to the figures, this closure is applied to a tank made of sheet metal comprising a tubular body 10 and having a lower end 11 attached to a bottom wall 12 and an annular upper wall attached by means of a double seam 14 The upper end 13 of the annular upper wall 15 internally defines a seat 16 for sealingly receiving the cover 20 . The illustrated tubular body 10 has a circular cross-section, however, it is understood that the cross-section may be other than circular.

[0023] The configuration of the annular upper wall 15 and the base 16 can be in different ways as long as it allows the lid 20 to fit tightly and securely in the upper part of the can. In Figures 4 and 5, the annular upper wall 15 and base 16 are constructed as in Brazilian patent PI 9408643-5 issued to the same applicant in Brazil and in other countries to the same applicant (eg US 5,899,352 in the United States). , in Europe as described and claimed in EP 0706486), so its detailed description ...

Abstract

The invention discloses a closure device for a canister of the type comprising: a tubular body (10) having an open upper end (13) with a base (16); and a plastic cover (20), Said cover comprises a seal (21) and an axially breakable seal (25) formed by a lower skirt (25a) seated around the upper end (13) of the tubular body (10) and by means of a breakable seal (25). The broken radial bridge (26) is internally bonded to the upper edge (25b) of the seal (21). The cross-sectional profile of the upper end (13) of the tubular body (10) is substantially smaller than the maximum cross-sectional profile of the remainder of the tubular body (10), so that the profile of the cover (20) remains at said maximum cross-sectional profile of the tubular body (10). within the cross-sectional profile, thereby avoiding mutual contact between the lids (20) of two adjacent cans arranged side by side.

Description

technical field [0001] The present invention relates to improvements in closure arrangements for cans, obtained in sheet metal and of the type comprising a tubular body, with the lower edge attached or incorporated with the bottom wall, the upper edge directly By means of the deformed part of the tubular body or by means of the annular upper wall part which may be in the form of a structural ring, a seat is carried for seating and holding the press-fitted plastic cover. In particular, the invention relates to a closure with a plastic lid for cans of the above-mentioned type intended to contain products that are consumed gradually, such as certain food products. Background technique [0002] Expired products, such as certain food products, must be stored airtight and provide consumers with a clear visual indication that the containers in which these products appear in the market have not been compromised. Considering that many of these products are consumed gradually, it mus...
