Description

Antiseep lid that paper jar was used

Technical Field

The utility model relates to the technical field of paper can covers, in particular to an anti-leakage cover for a paper can.

Background

The paper can is a round packaging product integrating metal, paper and plastic into a whole, and is generally divided into a spiral type and a rewinding type. Paper cans on the market at present are generally used for containing dry goods such as biscuits and tea leaves and cannot be used for containing liquid. The main reason for this is that the lid typically snaps directly onto the top edge of the carton with the lid edge. With this type of closure, the seal between the lid and the can body is poor and if used to contain a liquid, the solution is prone to leaking from the edges of the lid. How to design a cover which can be suitable for a paper can and can achieve the anti-leakage effect becomes a technical problem which needs to be solved urgently in the field.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects of the prior art and provide a leakage-proof cover which can be used for a paper can.

The technical scheme adopted by the utility model is as follows: the utility model provides an antiseep lid that paper jar was used the edge of lid be provided with the connecting portion that closely cooperate with the paper jar opening, connecting portion include with paper jar opening edge zonulae occludens's circumference mounting groove, connecting portion be provided with the inner groovy that is used for the injecting glue in one side towards the centre of a circle, the opening orientation of inner groovy is opposite with centre of a circle place direction, the one end of inner groovy be connected with the one end of circumference mounting groove.

Preferably, the horizontal plane of the end of the inner groove connected with the circumferential installation groove is higher than the horizontal plane of the top of the circumferential installation groove.

Preferably, the cover is one of a pop-top cover, an easy-tear cover, an iron cover or an aluminum cover.

Preferably, the outer groove surface of the inner groove is obliquely arranged, and the inner groove surface is horizontally arranged.

Preferably, the connection surface of the inner groove and the circumferential installation groove is an arc surface.

Preferably, the height of the inner groove is 1-2 mm.

Preferably, the inner concave depth of the inner groove is 1.5-2.5 mm.

Compared with the prior art, the utility model has the following advantages: according to the cover, the inner side face of the edge of the cover is provided with the inner groove for injecting glue, so that a circle of sealant can be added to the edges of the cover and the paper tank body, and the sealing performance of the cover is greatly improved.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiment examples. The utility model can be implemented by:

referring to fig. 1-4, an anti-leakage cover for a paper can, the edge of the cover is provided with a connecting portion 1 closely matched with the opening of the paper can, the connecting portion 1 comprises a circumferential mounting groove 11 closely connected with the edge of the opening of the paper can, one side of the connecting portion 1 facing the center of a circle is provided with an inner groove 12 for injecting glue, the opening of the inner groove 12 faces the direction opposite to the direction of the center of a circle, and one end of the inner groove 12 is connected with one end of the circumferential mounting groove 11. Before the installation, pour sealed glue into inside 12 recess earlier, then utilize the rotatory riveting of the top edge joint of circumference mounting groove 11 and paper jar to can. According to the cover, a circle of sealant can be added to the edges of the cover and the paper tank body in a manner of injecting the glue into the inner groove 12, so that the sealing performance of the cover is greatly improved.

The horizontal plane of one end of the inner groove 12 connected with the circumferential installation groove 11 is higher than the horizontal plane of the top of the circumferential installation groove 11. By the design, the sealant is not easy to overflow into the circumferential mounting groove 11 in a large amount.

The upper cover is one of an easy-to-pull cover, an easy-to-tear cover, an iron cover or an aluminum cover. The inner groove 12, the circumferential installation groove 11 and the cover can be of an integrated structure, and production cost can be reduced. The height of the inner groove 12 is 1-2 mm. The inner concave depth of the inner groove 12 is 1.5-2.5 mm.

The outer groove surface 121 of the inner groove 12 is inclined, and the inner groove surface 122 is horizontal. The inner groovy 12 be the cambered surface with the connection face 123 of circumference mounting groove 11, this design can make the lid after the injecting glue close the in-process with the sealed lid of paper tank, sealed glue can spread on connecting the face 123 with inner groovy 12 and circumference mounting groove 11 by a small amount, increase sealed glue and the area of contact of the surface at paper tank top edge, strengthen sealed effect.

Finally, it should be noted that: the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
