Description

Technical Field

[0001] This utility model relates to the field of container sealing caps, and more particularly to a container sealing cap structure. Background Technology

[0002] A container is a closed or semi-closed structure used for holding, storing, transporting or using goods. It has an internal cavity to hold liquids, gases or solid particulate matter. To meet the storage requirements of liquids, containers need to have good sealing performance. Good sealing not only prevents the liquid inside the container from leaking, evaporating or being contaminated by the outside, but also improves its pressure resistance and service life.

[0003] However, when a container is filled with a hot liquid, the high temperature of the liquid causes the gas inside the container to expand thermally, resulting in a rapid increase in the internal pressure. At this time, the container's sealing structure will form a leakage channel under high pressure, causing the liquid to leak out, which can easily lead to burns or other safety risks, thus affecting the container's performance and user experience.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a sealing cap structure for a container that has a good sealing effect and prevents liquid leakage.

[0006] To achieve this objective, the present invention adopts the following technical solution: a sealing cap structure for a container, comprising a container body, a locking cap, and a sealing body;

[0007] The container body has an internal receiving chamber for holding liquid, and the top of the container body has an opening for allowing liquid to flow out of the receiving chamber;

[0008] The locking cap is detachably connected to the container body. The bottom of the locking cap is provided with a locking ring groove, and the bottom end of the sealing body is provided with an annular flange for engaging with the locking ring groove.

[0009] The sealing body at the upper end of the annular flange is provided with an arc-shaped groove that is recessed inward, and the inner wall of the locking cover is provided with an annular boss that is adapted to and locked in place with the arc-shaped groove.

[0010] The bottom of the sealing body is provided with a sealing strip that extends vertically downwards. The sealing strip is used to fit against the inner wall of the opening when the locking cap is connected to the container body.

[0011] Using the above technical solution, in the sealing cap structure of the container, the top of the sealing body is provided with a liquid outlet, the liquid outlet is connected to the receiving chamber, and the liquid outlet is used to allow the liquid inside the container body to flow out to the outside.

[0012] In the container sealing cap structure described above, the upper edge of the arc-shaped groove is provided with a limiting stop, which abuts against the top wall of the annular boss to restrict the sealing body from slipping out of the locking cap.

[0013] In the container sealing cap structure described above, the annular boss has an inwardly protruding pressure block at its top, and the side wall of the sealing body has a pressure groove that abuts against the pressure block.

[0014] Using the above technical solution, in the sealing cap structure of the container, a positioning block is provided on the inner side wall of the annular boss, and a positioning groove is provided on the side wall of the sealing body to engage with the positioning block;

[0015] The positioning block and the pressure block are arranged symmetrically about the center line of the sealing body.

[0016] Using the above technical solution, in the sealing cap structure of the container, the liquid outlet is one of a sucking nozzle, a drinking nozzle, or a liquid guiding hole.

[0017] Using the above technical solution, in the sealing cap structure of the container, the sealing body is provided with a one-way valve, which is used to connect the gas inside the container body with the gas outside.

[0018] Using the above technical solution, in the sealing cap structure of the container, the bottom of the sealing body outside the sealing strip is provided with a flat part, which is used to abut against the opening edge of the container body.

[0019] In the container sealing cap structure described above, one end of the locking cap is provided with a flip-connecting assembly, and the other end of the locking cap is provided with a locking and fixing assembly. The locking cap is flip-connected to the container body through the flip-connecting assembly, and the locking and fixing assembly is used to lock the locking cap to the container body when the locking cap is pressed into the opening.

[0020] Using the above technical solution, in the sealing cap structure of the container, the sealing body is made of food-grade silicone, TPE or TPU material.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The locking cap of this invention has a locking ring groove at the bottom, which can initially engage and fix with the annular flange at the bottom of the sealing body.

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 6 As shown, this utility model embodiment provides a sealing cap structure for a container, including a container body 1, a locking cap 2, and a sealing body 3; the container body 1 has an internal receiving chamber 10 for holding liquid, and the top of the container body 1 has an opening 100 for allowing liquid to flow out from the receiving chamber 10; after the user injects liquid into the receiving chamber 10, the sealing structure closes the opening 100 to prevent liquid leakage or external contamination; when the user needs to take out the liquid, simply open the sealing structure, and the liquid can flow out through the opening 100 at the top of the container body 1, realizing convenient pouring or drinking.

[0035] The locking cap 2 is detachably connected to the container body 1. The bottom of the locking cap 2 is provided with a locking ring groove 21. The bottom end of the sealing body 3 is provided with an annular flange 31 for engaging with the locking ring groove 21. The upper end of the sealing body 3 at the annular flange 31 is provided with an arc-shaped groove 32 recessed inward. The inner wall of the locking cap 2 is provided with an annular boss 22 that is adapted to engage with the arc-shaped groove 32. The locking cap 2 is provided with a locking ring groove 21 at the bottom, which can be used to engage with the sealing body 1. The annular flange 31 at the bottom of the sealing body 3 is engaged and snapped together. During assembly, the engagement between the annular flange 31 and the snapping groove 21 forms a preliminary fixation, allowing the sealing body 3 to be stably snapped into the locking cover 2. At the same time, to prevent the sealing body 3 from falling off or misaligning, its upper end is also provided with an inwardly recessed arc-shaped groove 32, which is adapted to the annular boss 22 corresponding to the inner wall of the locking cover 2, so as to form a secondary locking structure through the snapping engagement, thereby providing limiting support force in the axial and radial directions.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, the bottom of the sealing body 3 is provided with a downwardly extending sealing strip 33. The sealing strip 33 is used to adhere to the inner wall of the opening 100 when the locking cover 2 is connected to the container body 1, and to fit tightly along its inner circumference. When the pressure inside the container rises due to the presence of high-temperature liquid, the sealing strip 33 expands and squeezes outward under pressure, so that the outer wall of the sealing strip 33 is pressed tightly against the inner wall of the opening 100, thereby forming a dynamic sealing effect that becomes tighter under pressure, preventing liquid from seeping out of the gaps under high pressure, greatly improving the sealing effect of the container, and effectively improving the safety of the container during use.

[0037] like Figure 1 and Figure 2 As shown, the top of the sealing body 3 is provided with a liquid outlet 34, which is connected to the receiving chamber 10. The liquid outlet 34 is used to allow the liquid inside the container body 1 to flow out to the outside, thereby providing an outlet path for the internal liquid, making it convenient for the user to drink or pour out.

[0038] like Figure 2 As shown, the upper edge of the arc-shaped groove 32 is provided with a limiting stop 35. The limiting stop 35 abuts against the top wall of the annular boss 22 to restrict the sealing body 3 from sliding out of the locking cover 2. When the sealing body 3 is embedded in the locking cover 2, the limiting stop 35 can abut against the top wall of the annular boss 22, thereby preventing the sealing body 3 from sliding upward and improving the stability of the assembly structure between the sealing body 3 and the locking cover 2.

[0039] like Figure 2 and Figure 3As shown, the annular boss 22 is further provided with an inwardly protruding pressure block 23 on its top, and the side wall of the sealing body 3 is provided with a pressure groove 36 that abuts against the pressure block 23. When the sealing body 3 is installed into the locking cover 2, the pressure block 23 and the pressure groove 36 can form an interlocking contact to prevent the sealing body 3 from rotating within the locking cover.

[0040] like Figure 2 As shown, further, the inner sidewall of the annular boss 22 is provided with a positioning block 24, and the sidewall of the sealing body 3 is provided with a positioning groove 39 that engages with the positioning block 24. The positioning block 24 and the pressure block 23 are symmetrically arranged about the center line of the sealing body 3. This arrangement not only effectively prevents the sealing body 3 from rotating and displacing, but also has a positioning and error-proofing function, thereby improving the assembly efficiency of the sealing body 3.

[0041] like Figure 3 As shown, the liquid outlet 34 is further configured as a sucking nozzle, a drinking spout, or a liquid guiding hole. In this embodiment, the liquid outlet 34 is a sucking nozzle.

[0042] like Figure 4 As shown, the sealing body 3 is further provided with a one-way valve 37, which is used to connect the gas inside the container body 1 with the gas outside. External air can enter the container body 1 through the one-way valve 37 to balance the pressure difference between the inside and outside, so that the internal fluid can flow out smoothly from the container body 1.

[0043] like Figure 1 and Figure 6 As shown, further, the bottom of the sealing body 3 on the outer side of the sealing strip 33 is provided with a flat part 38. The flat part 38 is used to abut against the edge of the opening 100 of the container body 1. The flat part 38 can form an annular contact surface with the edge of the opening 100 of the container body 1, thereby achieving a double sealing effect and reducing the risk of liquid leakage.

[0044] like Figures 1 to 3 As shown, further, one end of the locking cover 2 is provided with a flip-connecting assembly 25, and the other end of the locking cover 2 is provided with a locking fixing assembly 26. The locking cover 2 is flip-connected to the container body 1 through the flip-connecting assembly 25, and the locking fixing assembly 26 is used to lock the locking cover 2 to the container body 1 when it is pressed against the opening 100. During operation, the user only needs to flip the locking cover 2 upwards to open the container body 1 without completely disassembling the locking cover 2. After use, it is flipped downwards and pressed and locked into the container body 1 by the locking fixing assembly 26, thereby achieving a sealed closure.

[0045] Furthermore, the sealing body 3 is made of food-grade silicone, TPE, or TPU. In this embodiment, the sealing body 3 is made of food-grade silicone.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
