Description

A low-cost, high-sealing-effect container sealing structure Technical Field

[0001] The present invention relates to the technical field of container sealing structures, and in particular to a low-cost, high-sealing-effect container sealing structure. Background Art

[0002] The currently commonly used container packaging in various shapes such as boxes, cups, and cans is usually sealed by only fastening the lid and the container. Such container products usually use easy-tear labels to assist in determining whether the product container has been opened. Although this schematic pseudo-sealing method can achieve the function of assisting judgment, it cannot assist in sealing. If only the lid and the container are fastened together for sealing, the sealing performance cannot be guaranteed. Therefore, there is room for improvement. Technical issues

[0003] A search revealed Chinese patent application number CN200420037947.1, which discloses a beverage container lid with a concave, but non-through, annular groove on its top surface. It also discloses a disposable, ultra-thin, sealed beverage container comprising the lid and a container body, the lid and body being fastened together by a locking mechanism, with a container wall thickness S ≤ 0.5 mm. The beverage container lid in the aforementioned patent has the following drawbacks: while the annular groove is provided to prevent reuse, the overall sealing of the container is insufficient and needs improvement.

Modes for Carrying Out the Invention

[0036] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0037] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0038] A low-cost, high-sealing-effect container sealing structure, as shown in FIG1-4, comprises:

[0039] A container body 7, wherein a reverse-rolled annular rim 8 is integrally provided on the outer side of the top of the container body 7;

[0040] The container cover 2 has an annular covering edge 3 integrally provided on the outer side of the container cover 2 and adapted to the annular edge 8. When the container cover 2 is closed on the container body 7, the annular covering edge 3 can cover the annular edge 8;

[0041] An annular seal, which is installed on the outer side of the annular covering edge 3 and the annular edge 8 in the covering state;

[0042] The annular seal comprises:

[0043] The annular sealing portion 1 has a shape that matches the annular covering edge 3 and the annular edge 8. A brittle fracture groove 6 is provided on one side of the annular sealing portion 1. When the annular sealing portion 1 is installed outside the annular covering edge 3 and the annular edge 8 in the covering state, the annular sealing portion 1 can be broken at the brittle fracture groove 6 by pressing a position near the brittle fracture groove 6.

[0044] An upper elastic buckle 4 is integrally provided on the inner side of the top of the annular sealing portion 1;

[0045] The lower elastic snap buckle 9 is integrally provided on the inner side of the bottom of the annular sealing portion 1. The annular sealing portion 1 is snapped onto the outer side of the top of the annular covering edge 3 through the upper elastic snap buckle 4. The annular sealing portion 1 is snapped onto the outer side of the bottom of the annular edge 8 through the lower elastic snap buckle 9. When the annular sealing member is installed on the outer side of the annular covering edge 3 and the annular edge 8 in the covering state, the container cover 2 is tightly fastened to the container body 7 based on the restrictions of the upper elastic snap buckle 4 and the lower elastic snap buckle 9.

[0046] By providing an annular seal, the annular seal can be used to provide auxiliary reinforcement between the container cover 2 and the container body 7, thereby ensuring the sealing of the structure. If the container cover 2 is to be opened, the annular seal 1 needs to be destroyed, thereby helping personnel to identify whether the container has been opened, thereby improving reliability. In addition, when the annular seal is destroyed, it will not affect the normal use of the container cover 2 and the container body 7 by personnel, and the practicality is strong.

[0047] In order to improve practicality; as shown in FIG1 , the annular sealing portion 1 is provided with a reminder mark 5 near the brittle fracture groove 6;

[0048] By setting the prompt mark 5, it serves as a prompt and improves practicality.

[0049] In order to improve practicality, as shown in FIG2 , one side edge of the annular sealing portion 1 is connected to one side of the annular edge 8 ; the annular sealing portion 1 can realize angular opening and closing deflection with the connection with the annular edge 8 as the axis.

[0050] In order to facilitate the buckling of the container cover 2 onto the container body 7, as shown in FIG4 , a plurality of inner protrusions 10 are integrally provided on the inner side of the annular covering edge 3. When the annular covering edge 3 is buckled onto the annular rim 8, the inner protrusions 10 are snapped onto the bottom of the annular rim 8.

[0051] By providing the inner protrusion 10 , the firmness with which the annular covering edge 3 is fastened to the annular rim 8 can be improved, thereby enhancing practicality.

[0052] In this embodiment, the container body 7 and the container cover 2 are in a matching box-shaped structure, and the annular sealing portion 1, the container cover 2 and the annular sealing member are in a matching circular structure.

[0053] In addition, the structure of the annular sealing portion 1, the upper elastic snap 4, and the lower elastic snap 9 is a fence form that can adapt to the transverse outer circumference and longitudinal thickness of container packaging covers of various shapes, wherein the upper elastic snap 4 and the lower elastic snap 9 can be continuous or discontinuous, and can be synchronously adapted according to the shape of the outer area of ​​the container cover 2 that needs to be adapted, such as circle, square, triangle, etc.

[0054] The material used for the annular seal is deformable and has the property of being tough and recoverable (for example, various types of elastic metals, plastics, starch, paper, wood, bio-based materials and other degradable materials, etc.).

[0055] In this solution, there are also various ways to complete the sealing of the container. First, the annular seal can be partially folded into place and connected to the container cover 2 or container body 7 to obtain a complete state to be sealed and covered, and then covered with the container body 7 or container cover 2 until the sealing assembly is completed.

[0056] Alternatively, the container cover 2 and the container body 7 may be covered first, and then the annular sealing member may be partially folded into place for assembly. The various sealing covering methods are not limited to one or more methods, so they are not listed in detail one by one.

[0057] The assembly process means and methods include but are not limited to (fully automatic or semi-automatic) (assembly line) production assembly, manual assembly, manual assembly using various tools, mechanical fully automated assembly, etc. Since they are not limited to one or some methods, they are not listed in detail one by one.
