Description

A cover structure for a tank opening

technical field

The utility model relates to the technical field of packaging cans, in particular to a cover structure for the opening of a can body.

Background technique

Packaging can (cylinder) refers to a packaging container with roughly the same cross-sectional shape throughout the can body, a short can neck, and a slightly smaller inner diameter of the can neck than the inner neck of the can body or without a can neck. It is a kind of rigid packaging. The packaging material has high strength, and the tank body has strong deformation resistance. The packaging operation is a filling operation, and then the can mouth is closed, which can be used as transport packaging, outer packaging, or commercial packaging and inner packaging.

At present, there are mainly two types of lids for packaging jars, the pull-top type and the screw-connect type. The pull-top type needs to be equipped with a rubber cover, but the sealing performance of the rubber cover is poor, and the screw-connect type may be damaged during transportation. If it is loose, it is easy to cause air leakage, and it is inconvenient to lock the cover.

Preferably, a plastic shell is sleeved on the outside of the magnetic rod, and a plastic cover is sleeved on the plastic shell.

Preferably, a U-shaped elastic sheet is fixedly connected to the inner side of one end of the cylinder body.

Preferably, the outer edge of the concave cover is provided with a limit step, and the limit step and the concave cover are provided in an integral molding structure.

Preferably, the surface of the cylinder body is provided with anti-skid lines.

Preferably, a sealing ring is adhered to the top of the tank body.

Compared with the prior art, the beneficial effects of the present utility model are:

The utility model is mainly composed of a concave cover, a cylinder body, a magnetic rod and other components. After the concave cover is screwed into the tank body, the spring in the cylinder body will squeeze the limit rod and insert it into the tank body. In the limit hole of the side wall, the position of the concave cover is locked to prevent the concave cover from loosening. When it needs to be opened, insert the magnetic rod into the cylinder block, and the magnetic rod will attract the limit rod. The iron sheet at one end can drive the limit rod out of the limit hole, and then screw the concave cover, which can also prevent children from opening it at will.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1 to 3 , the present invention provides a technical solution: a cover structure for a tank body opening, comprising a tank body 1 and a concave cover 2 , and the concave cover 2 is threadedly connected to the tank body 1 Inside, the top of the concave cover 2 is provided with a cylinder 3, the cylinder 3 communicates with the edge of the concave cover 2, so that the limit rod 4 can be inserted into the limit hole 7, the limit hole 7 is located at the upper end of the tank body 1, and a thread is reserved below it to prevent ventilation through the limit hole 7 and the cylinder body 3, and the surface of the cylinder body 3 is provided with anti-skid lines, which is beneficial to improve the hand and the cylinder body 3.
