Description

Connecting structure of pop-top cover and can body and pop-top can

Technical Field

The utility model discloses food packaging jar especially relates to easy open can.

Background

The traditional pop can comprises a can body with an open top and a disc-shaped pop cover pressed by a metal thin plate, wherein the edge of the pop cover is pressed at the open top of the can body, the metal curled edge of the cover and the can body ensures that the metal curled edge generates great bonding strength, and sealant on the cover fills the gap of the metal curled edge to seal the metal curled edge. Later, a plastic pop can is developed, a transparent can body enables a product to have characteristics, and a standard cover of a metal pop can is adopted as the cover, so that the plastic pop can is thinner at a curled edge, the sealing quality is poor, and the problem of poor sealing performance caused by cracking and the like of the edge stitching part of a plastic product and the metal pop can cover during can sealing is solved, so that the plastic pop can becomes a problem concerned in the industry. The method of the patent can reduce the sealant and save the cost, has the greatest advantages that the thickness of the curled edge of the plastic pop can body can be increased, the sealing strength of the plastic pop can is effectively improved, and the problem that the sealing performance is poor due to cracking and the like of the edge pressing part of the plastic can body and the metal pop can cover is solved.

Fig. 1 is a conventional coupling structure of a lid and a can body.

Fig. 2 shows a structure for connecting the lid and the can body according to a preferred embodiment of the present invention.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are used in a broad sense, and for example, "connected," may be fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements.

Referring to fig. 1, in the conventional pop can, some sealant is required to be filled between the pop can lid and the can body to show the sealing connection, so that the production process is complicated and the cost is high.

Referring to fig. 2, the present embodiment provides a connecting structure of a lid and a can, including: the top of the can body extends outwards along the opening in the radial direction to form a circle of skirt edge 11, and the edge of the easy-open cover 2 is pressed at the skirt edge 11 of the can body;

the edge of the easy-open cover 2 extrudes the skirt edge 11 in the pressing process, so that the skirt edge 11 deforms and fills a gap between the edge of the easy-open cover 2 and the skirt edge 11, and the skirt edge 11 is attached and sealed with the edge of the easy-open cover 2.

Specifically, the skirt 11 comprises a first portion 111 extending radially outwards, and a second portion 112 extending axially downwards; a gap is formed between the second part 112 and the plastic can body 1.

The edge of the easy-open cover 2 comprises an arc-shaped outer edge 21 and a straight edge 22 arranged at the end part of the arc-shaped outer edge 21, and the straight edge 22 extends upwards along the axial direction of the plastic tank body 1;

a clamping space for clamping the second portion 112 is formed between the straight edge 22 and the arc-shaped outer edge 21.

When connected, the straight edge is inserted into the slit. After the pressing, the skirt edge deforms to fill the clamping space and the space in the gap, so that reliable sealing connection is formed.

The above, only be the preferred embodiment of the present invention, but the design concept of the present invention is not limited to this, and any skilled person familiar with the technical field is in the technical scope disclosed in the present invention, and it is right to utilize this concept to perform insubstantial changes to the present invention, all belong to the act of infringing the protection scope of the present invention.
