Bulge forming apparatus for producing canned product, and canned product

Abstract

A bulge forming apparatus for producing a canned product and a canned product produced by the bulge forming apparatus are disclosed. The canned product comprises a can (1) having an mouth (13), a lid (2) having an extension (21), and contents filled in the can (1), wherein the lid (2) is fitted in the mouth (13) such that the extension (21) forms a fit with a sidewall (11) of the mouth to seal the can (1). The bulge forming apparatus (3) is configured to form at least one bulge (22) on one of the extension (21) of the lid (2) and the sidewall (11) of the mouth (13) after the lid (2) has been fitted in the mouth (13) of the can (1), and while the lid (2) is removed from the can (1), the convex surface of the at least one bulge (22) is engaged with the other of the extension (21) of the lid (2) and the sidewall (11) of the mouth (13) in such a way that the extension (21) and / or the sidewall (11) is destroyed. The apparatus can produce a canned product in a simple way and at a low cost, and the canned product has an anti-counterfeit function.

Description

technical field [0001] The present invention relates to an embossing device for preparing barreled (canned) products or products generally contained in open containers, in particular barreled paint products. The present invention also relates to barreled products, especially barreled paint products, produced by the embossing device. Background technique [0002] The traditional process of preparing paint products in barrels is to first fill the barrel with paint, and then press the barrel cover into the opening of the barrel. A defective of the bucket paint product that makes like this is, because the fit force between bung lid and packaging bucket relies only on the press fit between the two parallel surfaces of bung lid and packaging bucket to produce, so bucket paint product For example, when it is subjected to vibration or unintentional tipping during handling, transportation, etc., the lid is easily detached from the packaging barrel (jumping the lid), resulting in pai...

Problems solved by technology

A defective of the bucket paint product that makes like this is, because the fit force between bung lid and packaging bucket relies only on the press fit between the two parallel surfaces of bung lid and packaging bucket to produce, so bucket paint product For example, when subjected to vibration or unintentional tipping during handling, transportation, etc., the lid is easily detached from the packaging barrel (jumping the lid), resulting in paint leakage or contamination

Another drawback of traditional paint products in barrels is that the used genuine packaging barrels and barrel lids are easily used to fill counterfeit paints again, causing economic and reputational losses to the merchants

Existing anti-counterfeiting technologies include laser printing anti-counterfeiting trademarks on paint buckets or using anti-counterfeiting labels, but these technologies are not only complicated but also costly
