Description

Technical Field

[0001] The utility model relates to the technical field of metal can covers, and more specifically to an easy-pull cover for a metal can. Background Art

[0002] Metal cans are also generally called cans. The can lid and can body are produced separately and then assembled together. There are two types of materials used to make cans: aluminum and tinplate;

[0003] The production of easy-open lids for metal cans usually involves processing the material of the can lid itself to form a rivet, then putting a pull ring on the outer cover and riveting it, and then adding appropriate notches to form a complete can lid;

[0004] The existing easy-pull lids are used for different products according to the position of the notches, such as metal can lids used for cans, etc. (such as application number: CN202020738771.1, a can lid structure and a can); metal can lids used for beverages, etc. (such as application number: CN201821063278.3, a can lid), etc.;

[0005] For the metal can lids used for the above-mentioned cans, the pull ring needs to be lifted up to a larger angle in order to open the opening large enough for easy pulling, and the pull ring angle needs to be adjusted when pulling. In this case, the operation is troublesome and the pull ring is easily broken. Utility Model Content

[0006] The purpose of the utility model is to solve the above technical problems and provide an easy-open lid for a metal can.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] The utility model provides an easy-open lid for a metal can, comprising a lid body, a circular impression is arranged on the lid body, a rivet for limiting the displacement of a pull ring is fixed on the lid body, an expansion plate is fixedly connected to the pull ring, a pressure strip located above the impression is fixedly arranged at the bottom end of the expansion plate, the pressure strip is turned over by the pull ring at the rivet, the pressure strip contacts the top of the lid body on the inner side of the impression and the contact end is close to the impression, and the length of the pressure strip corresponding to the impression position is greater than the length of the pull ring 4 corresponding to the impression 2 position;

[0009] As a preferred technical solution of the utility model, the distance between the bottom end of the pressure strip and the cover body gradually increases along the path of the imprint at the position of the pressure strip corresponding to the center of the pull ring flipping direction.

[0010] As a preferred technical solution of the present invention, the pressure strip corresponds to an impression having an arc shape.

[0011] As a preferred technical solution of the utility model, the imprint is centered inside the cover body.

[0012] As a preferred technical solution of the utility model, the rivet is arranged on the inner side of the impression.

[0013] As a preferred technical solution of the utility model, a groove located at the top of the cover body is provided under the pull ring.

[0014] The beneficial effects of the utility model are as follows:

[0015] By fixing an expansion plate 5 on the pull ring 4, a pressure strip 7 is fixed at the bottom end of the expansion plate 5, and the pressure strip 7 is flipped over at the rivet 3 through the pull ring 4, and the pressure strip 7 contacts the top of the cover body 1 on the inner side of the imprint 2 and the position where the pressure strip 7 contacts the top of the cover body 1 is close to the imprint 2, and the position where the pressure strip 7 and the pull ring 4 correspond to the imprint 2 is that the length of the pressure strip 7 is larger, that is, when the pressure strip 7 contacts the cover body 1 to press open the imprint 2 at this position, the pressure strip 7 with an enlarged range can contact the cover body 1 to press open the imprint 2, which can reduce the flipping angle of the pull ring 4, simplify the operation and improve the bending protection of the pull ring; the distance between the bottom end of the pressure strip 7 and the cover body 1 gradually increases along the path of the imprint 2 at the position where the pressure strip 7 corresponds to the flipping direction of the pull ring 4, which can obtain a better concentrated force effect and facilitate pressing.

[0018] Figure numerals: cover body-1, imprint-2, rivet-3, pull ring-4, expansion plate-5, groove-6, pressure strip-7. DETAILED DESCRIPTION

[0019] like Figure 1~2 As shown, the utility model proposes: an easy-open lid for a metal can, comprising a lid body 1, on which a circular impression 2 is provided, wherein the impression 2 is centered on the inner side of the lid body 1 (as shown in the figure, centered on the top of the lid body 1);

[0020] The cover body 1 is fixed with a rivet 3 for limiting the displacement of the pull ring 4 (the rivet 3 is used to stabilize the position of the pull ring 4 on the upper cover body 1), as shown in the figure: the rivet 3 is arranged on the inner side of the imprint 2;

[0021] Wherein, a groove 6 is provided under the pull ring 4 at the top of the cover body 1, into which a finger can be inserted to facilitate contact with the pull ring 4 to lift it upwards;

[0022] The pull ring 4 is fixedly connected with an expansion plate 5 (such as Figure 2As shown, it can be symmetrically arranged on the pull ring 4 along the imprint 2);

[0023] The bottom end of the expansion plate 5 is fixed with a pressure strip 7 located above the imprint 2, and the pressure strip 7 is turned over at the rivet 3 via the pull ring 4 (according to the above, the pull ring 4 turns up, which can drive the pressure strip 7 to turn down);

[0024] The pressure strip 7 contacts the top of the cover body 1 on the inner side of the imprint 2 and the contact end is close to the imprint 2 (the downward-turned pressure strip 7 contacts the top of the cover body 1 and is arranged at a position close to the imprint 2 in order to increase the strength of the force);

[0025] The length of the pressure strip 7 corresponding to the position of the imprint 2 is greater than that of the pull ring 4 corresponding to the position of the imprint 2 (as shown in the figure, that is, according to the divergent direction of the center of the imprint 2, the part of the imprint 2 facing the pull ring 4 in the direction of the imprint 2 is smaller than the part of the imprint 2 facing the pressure strip 7 in the direction of the imprint 2), thereby increasing the range of hard pressing, opening the range more quickly, and reducing the turning-up angle of the pull ring 4;

[0026] The distance between the bottom end of the pressure strip 7 and the cover body 1 gradually increases along the path of the imprint 2 at the position of the pressure strip 7 corresponding to the center of the flipping direction of the pull ring 4 (such as Figure 1 As shown, that is, the pull ring 4 is flipped and centered at the position facing the imprint 2, and the thickness of the pressure strip in the path direction from this position to the imprint 2 gradually decreases), the position of the maximum thickness of the pressure strip 7 contacts the top of the cover body 1, and pressure is applied at this position, which can obtain a better concentrated force effect and facilitate pressing and opening; at the same time, after the position of the maximum thickness of the above-mentioned pressure strip 7 is pressed open, the pressure strip 7 with gradually decreasing thickness continues to press and open the imprint 2, and the smoothness of the pressing and opening is good, which can help the cover body 1 on the inner side of the imprint 2 to be pulled open.

[0027] The pressure strip 7 is in an arc shape corresponding to the shape of the imprint 2, and a pressure-applying component is arranged corresponding to the shape of the imprint 2, which can improve the stability of the pressure application.

[0028] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model.
