Description
Technical Field
The utility model relates to the technical field of easy-open ends, in particular to a pull ring type easy-open end capable of eliminating scribed line stress.
Background
The conventional easy-open lid generally comprises a lid body and a pull ring, wherein the lid body is provided with a closed annular score line for opening conveniently, an area surrounded by the closed annular score line on the lid body forms a sealing pull tab, and the pull ring is riveted with one end part of the sealing pull tab through a rivet. When the pull ring is pulled upwards, the pull ring drives the sealing pull piece to be torn along the annular score line and completely separated from the cover body, so that the opening of the cover body is exposed, and the materials in the easy-open can are conveniently poured out.
The existing sealing pulling-on piece is generally triangular, an opening of a material after the sealing pulling-on piece is pulled open is also triangular, and the triangular opening is large. Aiming at the easy-open cans for containing the light milk products, the light milk products are required to be poured out from the openings slowly, and if the light milk products are poured out from the larger triangular openings, too many light milk products are easily poured out at a time, so that waste is caused.
Disclosure of Invention
The utility model aims to provide a pull-tab type easy-open end capable of eliminating marking stress, which has a small opening width and is easy to control the pouring amount of a light milk product.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:
the utility model provides an eliminate pull ring type easy-open end of groove stress, includes lid and pull ring, and the pull ring is equipped with annular score line including connecting ring and connecting portion integrative on the lid, and the region that the annular score line encloses on the lid constitutes a sealed pulling-on piece, and the connecting portion of pull ring pass through rivet and the inner riveting of sealed pulling-on piece, its characterized in that: the sealing pull piece is a strip-shaped pull piece, the strip-shaped pull piece comprises a strip-shaped piece and a tongue tip piece, the inner end of the strip-shaped piece forms the inner end of the sealing pull piece, the outer end of the strip-shaped piece is integrally connected with the inner end of the tongue tip piece, and the outer end of the tongue tip piece is close to the edge of the cover body.
In order to prevent that the quick opening from easy-open end of the product of the type of giving up light milk from flowing, the producer changes the sealed pulling-on piece of triangle-shaped into bar tab, and bar tab is pulled back and can be formed the strip form opening on the lid, and for traditional triangle-shaped opening, the open-ended width of strip form diminishes, the pouring amount of the product of the type of giving up light milk of easy control, avoids the product of the type of giving up light milk to pour out too many once, causes the waste.
As a preferable aspect of the present invention, the strip-shaped piece has a width smaller than that of the tongue tip piece.
As a further preferable scheme of the utility model, the width of the strip-shaped piece is 20mm-40mm, and the width of the tongue tip piece is 30mm-80 mm.
