Abstract

A packaging can with good sealing performance comprises a can body, a pull ring bottom cover and a top cover; the bottom of the can body is provided with a bulge, the inner wall of the bulge is provided with a pull ring joint, the edge of the pull ring joint is flush with the inner wall of the can body, the pull ring bottom cover is connected with the pull ring joint, and the top cover is connected with the top of the can body. The utility model has simple structure and convenient manufacture, and compared with the common packaging tank, the sealing performance of the tank body can be greatly improved by using a welding mode, thereby avoiding influencing the quality of the articles in the packaging tank; because the bottom of the can body is provided with the bulge, the edge of the connecting part of the pull ring cannot exceed the inner wall of the can body when a user pulls the pull ring bottom cover open, thereby reducing the danger of cutting injury; when the can bodies without the bottom covers are stacked together for storage, the can bodies are not easy to shake and convenient to store, and the bottom of the can body is provided with the bulges, so that the can bodies are not easy to fall down due to the increase of the contact area with the ground.

Description

Packaging can with good sealing performance

Technical Field

The utility model relates to a packing jar, especially a packing jar that leakproofness is good belongs to the packing utensil field.

Background

Red ginseng is generally stored by using a packaging can, and most of the packaging cans are tinplate cans, namely cans made of tinplate, and are classified into round cans, rectangular cans, square cans, hand-push boxes, special-shaped cans (heart-shaped/oval-shaped/automobile-shaped/cartoon-shaped) and the like according to shapes. At present, the pull ring packaging tin on the market generally adopts the manufacturing process of plate shearing, corner cutting, notch cutting, edge curling, end folding, rounding, flattening and bottom sealing, however, the pull ring packaging tin produced by the manufacturing method has relatively poor sealing performance and easily influences the quality of red ginseng in the tin; when the can body without the bottom is stored, a stacking mode is generally adopted, and the area of the bottom of the general can body is equal to that of the top of the general can body, so that the can body can shake after being stacked together, and the can body is poor in stability and not beneficial to storage; when the tab lid of pull open packing jar, the pull ring junction of can body generally can take place deformation and turn over to the outside, when the user need stretch into the packing jar with the hand, because the pull ring junction is comparatively sharp, can cut user's hand, consequently uses comparatively dangerously.

SUMMERY OF THE UTILITY MODEL

To the deficiency of the prior art, the utility model provides a simple structure, packing jar that the leakproofness is good.

In order to achieve the above object, the utility model adopts the following technical scheme: a packaging can with good sealing performance comprises a can body, a pull ring bottom cover and a top cover; the can body junction be equipped with the welding seam, can body bottom is equipped with the arch, is equipped with the pull ring junction on the bellied inner wall, the edge of pull ring junction and the inner wall parallel and level of can body, pull ring bottom be connected with the pull ring junction, the top cap is connected with can body top.

Preferably, the area of the top cover is smaller than the area enclosed by the protrusions.

Preferably, the tank body is a cuboid.

Preferably, the can body is a cylinder.

The utility model has simple structure and convenient manufacture, and compared with the common packaging tank, the sealing performance of the tank body can be greatly improved by using a welding mode, thereby avoiding influencing the quality of the articles in the packaging tank; because the bottom of the can body is provided with the bulge, when a user pulls the pull ring bottom cover open, the connecting part of the pull ring deforms and sinks into the bulge at the bottom of the can body, and the edge of the connecting part does not exceed the inner wall of the can body, so that the danger that the user stretches the hand into the packaging can and is cut by the connecting part of the pull ring is reduced; when the can bodies without the bottom covers are stacked together for storage, the area of the top cover is smaller than the area surrounded by the protrusions at the bottom of the can bodies, so that the stacked can bodies are not easy to shake and convenient to store, and the contact area between the bottom of the can bodies and the ground is increased due to the protrusions arranged at the bottom of the can bodies, so that the can bodies are good in stability and not easy to fall down.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5: a packaging can with good sealing performance comprises a can body 1, a pull ring bottom cover 2 and a top cover 3; can body 1 be the cuboid, can body 1's junction is equipped with welding seam 5, can body 1 bottom be equipped with

arch

4, 3 long wide 7.8cm, 3.8cm respectively of top cap, 4 long wide 8cm, 4cm respectively of arch, top cap 3's area is less than the area that arch 4 encloses, is equipped with pull ring junction 6 on 4's the inner wall of arch, and pull ring junction long wide 8cm, 4cm respectively, and the edge of pull ring junction 6 is 0.5cm with protruding 4's distance L, can body inner wall long wide 7.5cm, 3.5cm respectively, pull ring junction 6's edge and can body 1's inner wall parallel and level, pull ring bottom 2 be connected with pull ring junction 6, top cap 3 is connected with can body 1 top.

During this packing jar production, earlier according to the demand with the sheet crooked and weld for the can body of shape such as cuboid (adopt the leakproofness that welded mode can improve the can body by a great margin), then with the outside punching press in bottom of can body form a arch, seal can body top through the top cap simultaneously, be connected pull ring bottom and pull ring junction to realize the sealed effect of whole packing jar. When the can bodies without the bottom covers are stacked together for storage, the problem of shaking between the stacked can bodies is not easy to occur (as shown in fig. 5) because the area of the top cover is smaller than the area surrounded by the protrusions at the bottom of the can bodies. When a user pulls the pull ring bottom cover open, the pull ring joint at the bottom of the can body can deform and sink into the bulge at the bottom of the can body, so that the edge of the pull ring joint cannot exceed the inner wall of the can body, and the situation that the hand of the user is cut is reduced.
