Abstract

The utility model provides an easy open can which comprises a can body 1, a tinplate easy-pull top 2 with a mark 4, and a pull-tab 3. More than one concave mark 5 or convex mark 6 is formed on the tinplate easy-pull top 2, and the concave mark 5 or convex mark 6 is vertical to the mark 4, and is parallel to the pull-tab 3. In order to ensure the shelf lives of the canned goods and enable a user to conveniently open the easy-pull top, the down-concave depth H1 of the concave mark 5 or the up-convex depth H2 of the convex mark 6 is 0.2 to 0.5 mm. Under the condition that the depth of the mark line on the easy open can is ensured to be the pre-set value, adopting the easy open can of the utility model can still produce a downward pressing stress to the mark line even if the mark line on the easy open can is still uneven due to the material during the actual pressure-charging, thereby enabling the pulling-up force along the mark 4 to be smaller and lighter compared with the traditional structure (elliptical expansion ring) when people pulls up the pull-tab 3, thus, the can cover is easier to be opened.

Description

Pop can

Technical field

A kind of pop can is specifically related to adopt the improvement of tin-plate as the cover of pop can structure.

Background technology

The present domestic pop can that uses tin-plate as carnivorous can on the market, in particular for carrying aquatic products canned fish cover of pop can, all be pressed with line of weakness on its cover, to be convenient for people to the draw ring pull-up on the pop can, along line of weakness cover is drawn back, in order to enjoy the tinned food in the pop can.But such pop can, because the easy-open lid material all adopts the tin-plate (pop can of carrying beverage class in general jar, its easy-open lid material only adopts the softer aluminum alloy of material), be subjected to the restriction (comprising technologies such as needs consideration thermophilic digestion, sterilization) that the hardness of material own is high and manufacture, difficult grasp of weight to line of weakness, the weight of line of weakness is extremely important to the shelf-life and the seal request of pop can, line of weakness is carved when dark, the indentation surplus diminishes, though cover pull-up easily, but the shelf life storage in the tank body leak tightness variation, pop can shortens; Line of weakness is carved shallowly or indentation when carving inhomogeneously, and cover is difficult for pull-up, and needs the bigger power that opens broken and crack force, and damage is pointed easily simultaneously.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of pop can, its cover of pop can adopts the tin-plate manufacturing, indenture or the convex epirelief expansion of the transverse design (circle) are set on easy-open lid, utilize the interaction force of line of weakness and indenture or convex epirelief, people can make things convenient for and open cover of pop can easily.

The pop can of the said structure of the utility model is made up of tank body 1, the easy-to-draw lid 2 of tin-plate and the draw ring 3 that have an indentation 4, is provided with one or more indenture 5 or convex epirelief 6 on the easy-to-draw lid 2 of tin-plate, and indenture 5 or convex epirelief 6 are vertical and parallel with draw ring 3 with indentation 4.In order to guarantee the shelf-life of this class can, and allow the user can open easy-open lid easily, the recessed depth H 1 of said indenture 5 is 0.2～0.5mm, or the epirelief height H 2 of convex epirelief 6 is 0.2～0.5mm.

Adopt the pop can of the said structure of the utility model, in the degree of depth that guarantees the pop can line of weakness is under the situation of specified value, even because the line of weakness on the material cause easy-open lid still produces line of weakness when inhomogeneous in actual pressurising, owing on the easy-to-draw lid 2 of tin-plate, be provided with one or more indenture 5 or convex epirelief 6 (horizontal indent expansion loop), indenture 5 or convex epirelief 6 are vertical and parallel with draw ring 3 with indentation 4, still can produce a kind of compression effort down to line of weakness, make people when pull-up draw ring 3, diminish along the pulling force of indentation 4 pull-ups pulling force than conventional confguration (oval expansion loop), lighten, so the easier unlatching of cover.

Description of drawings

Fig. 1 is the scheme drawing of the said pop can of the utility model;

Fig. 2 is the indenture generalized section of the said pop can of the utility model;

Fig. 3 is the convex epirelief generalized section of the said pop can of the utility model.

The specific embodiment

Be described further below in conjunction with accompanying drawing.

As shown in Figure 1, the pop can of the said structure of the utility model is made up of tank body 1, the easy-to-draw lid 2 of tin-plate and the draw ring 3 that have an indentation 4, be provided with one or more indenture 5 or convex epirelief 6 on the easy-to-draw lid 2 of tin-plate, indenture 5 or convex epirelief 6 are vertical and parallel with draw ring 3 with indentation 4.When the pull-up draw ring is opened the easy-to-draw lid 2 of tin-plate, pulling force on indenture 5 or convex epirelief 6 with along the pulling force mutual action of line of weakness 4, offset the part pulling force, even the indentation surplus of pop can line of weakness is big or indentation is inhomogeneous, the easy-to-draw lid 2 of tin-plate is also opened easily.

As Fig. 2, shown in Figure 3, the pop can of the said structure of the utility model, can accept the boiling under the high temperature, the pressure of sterilizing in order to guarantee this class can at production period, guarantee again simultaneously to form the later transportation of product, sell the shelf-life, also to allow the user can open easy-open lid easily, therefore recessed depth H 1 the best of pressure-formed indenture 5 is 0.2～0.5mm on the easy-to-draw lid 2 of tin-plate, or epirelief height H 2 the bests of convex epirelief 6 are 0.2～0.5mm.

Claims

1, a kind of pop can, form by tank body (1), the easy-to-draw lid of tin-plate (2) that has indentation (4) and draw ring (3), it is characterized in that being provided with on the easy-to-draw lid of said tin-plate (2) one or more indenture (5) or convex epirelief (6), indenture (5) or convex epirelief (6) are vertical with indentation (4) and parallel with draw ring (3).

2,, it is characterized in that the recessed depth H 1 of said indenture (5) is 0.2～0.5mm, or the epirelief height H 2 of convex epirelief (6) is 0.2～0.5mm as the said pop can of claim 1.
