Description

Easy-open lid capable of stably stacking pop-top can

Technical Field

The present invention relates to an easy open lid, and more particularly, to an easy open lid capable of stably stacking cans.

Background

The existing pop can is usually provided with a pull cover frame extending upwards at the outer edge of the cover body, and the bottom surface frame extending downwards is arranged at the outer edge of the bottom surface of the pop can, so that the pop can be stacked up simply by being stacked up and down when being stored. Because the pop can cover body needs to be provided with a pull ring, when the pop can cover body is stacked, if the bottom surface of the pop can positioned above is contacted with the pull ring of the pop can positioned below, the pull ring can lift the bottom surface of the pop can, so that the gravity center of the pop can positioned above is shifted; and increase the height of the bottom surface frame of easy open can, the bottom surface and the pull ring contact of easy open can when can avoid piling up, but this kind of setting can lead to the easy open can too high at the in-process focus that piles up, and the easy open can is unstable when piling up, rocks easily and collapses, can't pile up higher height.

When the pop can is stacked, the circular or oval annular score line of the common easy-open lid is adopted, and the bottom frame of the pop can above the top can continuously applies pressure to the annular score line due to the fact that the outline of the bottom frame is the same as that of the annular score line, so that the annular score line is easy to break. The ring-shaped score line is set to be composed of a major arc section and two easy-opening sections, the two straight easy-opening sections are far away from the outer edge of the ring-shaped concave surface, the outline of the ring-shaped score line is not the same as the bottom frame of the pop can, the bottom frame of the pop can above the ring-shaped score line has a part of force applied to other positions on the ring-shaped concave surface, and the convex hull can share certain stress, so that the ring-shaped score line can be effectively prevented from being broken, meanwhile, the connecting part of the two easy-opening sections forms an opening tip, so that the pull ring moves inwards to the cover body, when the pull ring is pulled upwards, the opening tip is pressed downwards by the opening end of the pull ring and is torn towards two sides along the two easy-opening sections, and opening is easier; meanwhile, the radian of the easy-opening section is gentle, so that the pull cover can quickly open the gap along the easy-opening section.

In a preferred embodiment, the two easy-opening sections are inclined line sections inclined outward from the opening tip. The easy-opening section can be a straight section or an arc section.

In a preferred scheme, the upper edge of the cover body is also provided with an auxiliary score line, and the auxiliary score line extends from the rear end of the riveting end of the pull ring to the outer sides of two sides. When the pull cover is opened, the pull ring takes the rear end of the riveting end as a fulcrum, the pull ring is pressed downwards from the opening end to the rear end of the riveting end, the auxiliary score line is arranged to enable the riveting end of the pull ring to be pressed down more easily, and the opening end of the auxiliary pull ring opens the pull cover.

In a preferred embodiment, each convex hull is in a spherical crown shape.

In a preferable scheme, the central cover surface is a concave surface, at least two salient points are arranged on the central cover surface, and the salient points are positioned below the pull handle of the pull ring and lift the pull handle. The convex points are arranged, so that a user can lift the handle when needing to open the pull cover.

In a preferable scheme, the height of the convex hull is 0.2-0.22mm higher than the height of the highest point of the pull ring. By adopting the arrangement, the height of the frame on the bottom surface of the pop can be reduced as much as possible under the condition that the convex hull supports the bottom surface of the pop can.

The utility model has the beneficial effects that: the easy open lid can facilitate the stacking of a plurality of pop cans and keep the pop cans stable in the stack.
