Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealed containers, and more particularly to a stable and securely fastened sealed container. Background Technology
[0002] Traditional sealed containers often employ a single-layer sealing ring structure, relying on elastic deformation to achieve a seal after the lid and container are closed. However, when the container is subjected to radial forces, the lid is prone to radial displacement, resulting in excessive compression deformation on one side of the sealing ring, while the other side loses contact and loses its sealing effect. Especially for L-shaped cross-section sealing rings, although the double-layer structure formed by folding can enhance the sealing performance, the larger compression space of the double-layer structure under external forces exacerbates the risk of lid displacement. Utility Model Content
[0003] The purpose of this invention is to provide a stable and secure sealing container to solve the problem of large radial displacement of the lid in existing sealing containers using L-shaped sealing rings.
[0004] The technical solution of this utility model is: a stable and securely fastened sealing container, comprising a box body, a lid body, and a sealing ring;
[0005] The cross-section of the sealing ring is set to an L-shaped structure;
[0006] One side wall of the cover is configured as a mounting surface for mounting a sealing ring, and the mounting surface is provided with a radial limiting part and a receiving part;
[0007] When closed, a portion of the sealing ring is disposed within the receiving portion;
[0008] The radial limiting part has an outer wall that extends beyond the receiving part. When the cover moves relative to the box body in a direction perpendicular to the closing direction, the portion of the sealing ring that is in contact with the radial limiting part enters the compression limit state before the portion that is in contact with the receiving part.
[0009] Preferably, the cross-sections of the accommodating portion and the radial limiting portion along the covering direction are both configured as inverted trapezoidal structures.
[0010] Preferably, the protruding wall surface of the radial limiting portion forms a stepped structure and is configured as a stop end of the sealing ring. During the closing process, the stop end is used to restrict the movement of the sealing ring along the closing direction.
[0011] Preferably, the cover has a closing limiting part at the top of the mounting surface, the closing limiting part has an outer wall surface that extends beyond the radial limiting part, and can abut against the top of the box body during the closing action.
[0012] Preferably, the cover has an anti-detachment stop at the bottom of the mounting surface. The anti-detachment stop has an outer wall that extends beyond the receiving part, and its top end can abut against the bottom end of the sealing ring during the opening action.
[0013] Preferably, the cover limiting part and the anti-detachment stop part are both integrally formed with the cover body.
[0014] Preferably, a glass is embedded in the center of the cover.
[0015] Compared with the prior art, the advantages of this utility model are:
[0016] (1) In this application, the radial limiting part and the receiving part of the mounting surface work together to house the double-layer structure of the folded sealing ring in the receiving part, while the single-layer structure fits the radial limiting part. When subjected to radial force, the single-layer structure is preferentially compressed to the limit state, which significantly reduces the offset of the cover and avoids unilateral sealing failure.
[0017] (2) The cover limiting part, the anti-detachment stop part and the cover body are integrally injection molded, which reduces the assembly process, enhances the overall structure and avoids the risk of fatigue fracture of the separate parts. Attached Figure Description

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0026] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.
[0028] The present invention will be further described in detail below with reference to specific embodiments:
[0029] like Figure 1 - Figure 4 As shown, a securely fastened sealing container includes a box body 1, a lid body 2, and a sealing ring 3.
[0030] One side wall of the cover 2 is configured as a mounting surface 4 for mounting a sealing ring 3, and the sealing ring 3 is fitted onto the mounting surface 4. In this embodiment, the cover 2 is circular; in other embodiments of this application, the cover 2 may also be rectangular or other shapes.
[0031] The sealing ring 3 described in this application has an L-shaped cross-section through its own axis. During the closing process, the horizontal end of the L-shaped structure of the sealing ring 3 will abut against the inner wall of the box 1, and after bending, it will fit against the vertical end of the L-shaped structure, thereby achieving a sealing effect.
[0032] The structural design of this sealing ring 3 allows the cover 2 to be sealed with the box 1 through a double-layer sealing ring 3, which is made of elastic materials such as rubber. Therefore, after the cover 2 is closed with the box 1, the cover 2 can move radially under the action of an external force by compressing the double-layer structure of the sealing ring 3. This movement can cause the cover 2 to lose its coaxiality with the box 1, and the distal end of the compressed sealing ring 3 may lose contact with the box 1, thus causing the seal to fail.
[0033] To solve this problem, such as Figure 3 and Figure 4 As shown, the mounting surface 4 of the cover 2 in this application consists of two parts: a radial limiting part 5 and a receiving part 6. The radial limiting part 5 has an outer wall that extends beyond the receiving part 6, and the dimension of the receiving part 6 along the axial direction corresponds to the length of the horizontal end of the L-shaped structure of the sealing ring 3.
[0034] With this configuration, in the closed state, it combines Figure 5 As shown, the horizontal end and part of the vertical end of the L-shaped structure of the sealing ring 3 can be accommodated in the space corresponding to the receiving part 6. At the same time, the radial limiting part 5 fits against another part of the L-shaped structure of the sealing ring 3. Even if the double-layer part of the folded sealing ring 3 is accommodated in the receiving part 6, and the single-layer part abuts against the radial limiting part 5, when the cover 2 is subjected to external force and radial movement occurs, the radial limiting part 5 compresses the single-layer structure of the sealing ring 3 that is fitted to it to an incompressible state before the receiving part 6. Compared with compressing the double-layer structure, compressing the single-layer structure will result in a smaller deformation, thereby avoiding excessive movement of the cover 2 that could lead to seal failure on one side.
[0035] In addition, such as Figure 3 As shown, the cross-sections of both the accommodating portion 6 and the radial limiting portion 5 along their own axes are designed as inverted trapezoidal structures. This design not only reduces the size requirements of the opening of the box 1, but also allows for a close fit to the box 1, which is wider at the top and narrower at the bottom.
[0036] Furthermore, the protruding wall surface of the radial limiting part 5 forms a stepped structure and serves as the stop end 51 of the sealing ring 3. During the closing process, the stepped structure of the stop end 51 causes the sealing ring 3 to experience greater frictional force when moving axially, thereby restricting the axial movement of the sealing ring 3.
[0037] like Figure 4 As shown, the cover 2 has a closing limiting part 7 at the top of the mounting surface 4. The closing limiting part 7 has an outer wall surface that extends beyond the radial limiting part 5, so that the closing limiting part 7 can abut against the top of the box 1 during the closing action, which also means that the cover 2 is closed in place.
[0038] The cover 2 has an anti-detachment stop 8 at the bottom of the mounting surface 4. The anti-detachment stop 8 extends beyond the outer wall of the receiving part 6, allowing it to abut against the bottom of the sealing ring 3 during the opening action, preventing the sealing ring 3 from detaching from the cover 2. Furthermore, a glass element is embedded in the center of the cover 2, enhancing its rigidity while allowing the operator to observe the contents of the box 1 without opening the cover.
[0039] Furthermore, in this embodiment, both the cover limiting part 7 and the anti-detachment stop part 8 are integrally formed with the cover body 2.
[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
