Description

One-piece metal cover

Technical Field

The utility model belongs to the technical field of metal packaging, and particularly relates to a one-piece metal cover.

Background

At present, many food cans are composed of a can body and a can cover, the can body is an iron can, the can cover and the can body are separated, most of the food cans are plastic products, and the plastic cover is buckled on the top opening of the can body. Although the plastic cover is widely used for a long time, under the background that the packaging field is more and more focused on green environmental protection, the environmental protection performance of the plastic cover does not meet the aim, and the plastic cover is stored or used for a long time, the material of the plastic cover can change to cause the deformation of the cover, and the cover and the tank body are not tightly buckled, so that the sealability of the whole tank body is reduced to cause the moisture deterioration of the tank content.

Aiming at the problems of the plastic tank cover, the patent number is designed as follows: CN202022449134.5, the patent name is a metal composite top cover for a milk powder can, and as shown in fig. 6, the metal composite top cover for the milk powder can relates to an additional metal can cover for a standard can body. The novel energy-saving tank comprises a skirt and a top cover, wherein the skirt comprises a skirt ring sleeved on the top edge of the tank body and a buckling surface type waisted ring positioned above the skirt ring; the waist-folding ring is provided with a pivot clamping seat, the top cover is provided with a pivot hole corresponding to the pivot clamping seat, the pivot hole is formed by the edge rolling of the end edge of the top cover, and the top cover is connected with the pivot clamping seat on the waist-folding ring through a pivot to form a flip structure; the skirt pendulum ring is provided with a plurality of inward bulges/grooves which are equidistantly distributed, and a plurality of outward pits/bulges which are equidistantly distributed are arranged on the outer wall of the top edge of the tank body in cooperation with the bulges or grooves. The skirt ring is buckled on the tank body, so that the iron composite top cover and the tank body are tightly combined to ensure the tightness between the iron composite top cover and the tank body. Meanwhile, the metal composite top cover is odorless and tasteless, no harmful substances are separated out, and the safety of food in the can body can be better ensured, but the following difference points exist;

1. the patent consists of 3 parts, the manufacturing process is complex, the main manual assembly is realized, and the cost is high;

2. the pivot structure of the reference patent needs to be punched on the skirt, and a gap is formed in the pivot area after the flip cover is buckled, so that the tightness of the cover is affected.

Disclosure of Invention

In order to solve the above problem, this application has proposed a slice formula metal cover, and its cover is by a sheet metal sheet through stamping forming, and the edge has the lock face, again with the open part lock of body to carry out spacingly through the arch, replace the plastic cover that currently generally uses, promote the feature of the environmental protection of whole jar body packing, utilize the stable shape of metal material processing back simultaneously to be difficult for receiving the leakproofness of the environmental temperature influence improvement jar body of deformation.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a one-piece metal cover, includes the lid main part, the lid end of lid main part has the round lock face, lock face and lid main part link into an organic whole, and there is the evagination turn-up with the jar top circumferencial direction of the jar body that corresponds of lid main part, and the evagination turn-up cooperatees with lock face inside, the lock face below outside has inwards protruding, lid main part lock is behind the jar body top, inwards protruding card is in the evagination turn-up below, set up in the lock face with lock face surface complex elastic washer.

Further: the cover body is stamped from sheet metal in the range of 0.15mm to 0.30mm.

Further: the surface of the buckling surface is a horizontal surface, an inclined surface or an arc surface.

In the above structure:

the tank cover is provided with a buckling surface, and the surface of the buckling surface is a horizontal plane, an inclined plane or an arc surface; the inner surface of the buckling surface can be provided with a gasket, and the gasket is made of elastic materials such as plastic, rubber or silica gel; after the tank cover is buckled, the top of the tank body is contacted with the gasket and forms certain extrusion to the gasket, so that the sealing effect is achieved; the inner surface of the buckling surface is also not provided with a gasket, and in this case, after the tank cover is buckled, the top of the tank body is in hard contact with the inner surface of the buckling surface.

Further: the part between the buckling surface and the inward bulge is vertical, and after the cover main body is buckled above the can body, the inner surface of the vertical part and the outer surface of the outward convex curled edge form tight contact with a gap of 0.

Further: the inward protrusions have at least 2 and are equally spaced.

In the above structure:

inward bulges which are distributed at equal intervals are arranged below the buckling surface of the tank cover, and after the tank cover is buckled, the bulges are arranged below the curled edge at the top of the tank body, so that the limit function is realized, and the tank cover cannot easily fall out from the top of the tank; in addition, because the can body and the can cover are both metal, when the can cover is completely buckled, the interaction of the inner bulge of the can cover and the outer convex curled edge of the can body can generate a click sound, so that a user is reminded of completely buckling the can cover, and the use experience is promoted to be further.

Further: the bottom of the buckling surface is provided with a circle of outward curled edges.

Compared with the prior art, the utility model has the beneficial effects that:

1. the metal tank body is matched with the metal tank cover, and 100% recovery of the whole tank body can be realized;

2. the metal material has stable performance and is not easy to deform, and is matched with the metal can, compared with the plastic can cover, the metal can cover has better sealing performance, and can be matched with a sealing gasket, so that the sealing performance can be further improved;

3. when the metal can cover is buckled, a sound is made to prompt a user that the can cover is completely buckled, and the use experience is good.
