Description

Technical Field

[0001] This utility model patent relates to the field of packaging containers, in particular to a lid with a valve for dispensing viscous liquids. Background Art

[0002] Currently, there are various commonly used viscous foods on the market, such as honey and some seasonings. At the same time, the containers for holding such viscous foods not only serve the function of storage, but also affect the ability to pour out the food. A poor pouring effect will seriously reduce the user experience.

[0003] However, the containers for holding such viscous foods in the prior art face many problems that affect the pouring effect, including difficult flow control, backflow, residue, etc. When users use such containers to pour out viscous foods, it is difficult to accurately control the amount poured out, and excessive food will remain at the bottle mouth, which urgently needs to be solved. Summary of the Invention

[0004] The purpose of this utility model is to enable users to accurately control the amount poured out when using such containers to pour out viscous foods, while avoiding excessive food residue at the bottle mouth.

[0005] This utility model adopts the following technical scheme: It includes an inner lid and an elastic valve structure member. The elastic valve structure member is arranged in the middle of the inner lid. The middle part of the elastic valve structure member is a curved surface that is concave towards the inside of the bottle body. The edge of the curved surface is provided with a side edge towards the concave side. The inner lid includes a support platform, and the support platform is arranged on the inner lid close to the inside of the bottle body and is connected with the inner wall of the bottle body by interference fit.

[0006] The inner lid and the elastic valve structure member are of a split structure. The inner lid is in the structure of an annular gasket. An annular groove is provided in the inner ring of the annular gasket. An outward-turned edge is provided on the side edge of the elastic valve structure member, and the outward-turned edge is buckled in the annular groove and is in close fit with the annular groove. Through this technical scheme, the load can be effectively transmitted, making the elastic valve structure member less likely to fall off and ensuring the sealing performance.

[0007] The thickness of the middle part of the elastic valve structure member is thinner than that of the edge. The center part on the convex side of the elastic valve structure member is set as a flat surface, and the concave side is set as an arc surface, and the center thickness is 0.3 - 0.5 mm. Through this technical scheme, it is beneficial for liquid backflow, can reduce the risk of backflow and residue, ensure that the elastic valve structure member has good elasticity, so as to better cooperate with the extrusion of the bottle body, and then obtain better extrusion stability.

[0008] The elastic valve structure includes a notch provided in the middle, and the notch includes one of a cross-shaped, a rice-shaped, and a Y-shaped notch. Through this technical solution, it is beneficial for the elastic valve structure to rebound in time when the extrusion action is completed, and better control the quantitative outflow.

[0009] It further includes an outer cover, which is sleeved outside the inner cover and connected to the external thread on the bottle body. Through this technical solution, the inner cover and the elastic valve structure can be more effectively protected from external damage.

[0010] The bottle body is provided with an upper scale and a lower scale. Through this technical solution, the amount poured out can be controlled during and after the extrusion process.

[0011] The advantages and beneficial effects of the present invention are as follows: Through the elastic valve structure, users can accurately control the amount of viscous food poured out, avoid waste and excessive pouring, avoid food remaining at the bottle mouth, keep the bottle mouth clean, and reduce cleaning work; the elastic valve structure is recessed into the bottle body in its natural state, and the support platform fixes the inner cover to the bottle body to ensure that the container is in a sealed state when not in use; the center part of the convex side of the elastic valve structure is set as a plane, the concave side is set as an arc surface, and the center thickness is 0.3 - 0.5 mm. Through this technical solution, it is beneficial for liquid reflux and can reduce the risk of backflow and residue; the thickness design of the elastic valve structure ensures its good elasticity and the compatibility of the elastic valve structure, so that the viscous liquid can be better extruded when the bottle body is squeezed; the annular groove design on the inner cover makes the fixation of the elastic valve structure simpler, avoiding the risk of extrusion deformation and liquid leakage; the design of the outer cover effectively protects the inner cover and the elastic valve structure, avoids external damage, and extends the service life; the bottle body is also provided with scales for users to observe and determine the amount poured out during and after the extrusion process.

[0012] These advantages make this utility model have significant advantages when used in viscous food containers, improving the user experience and the practicality of the product. Description of the Drawings

[0017] The following will further describe the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0018] Referring to Figure 1 , upper and lower scales are respectively engraved at both ends of the bottle body, which can be used by the user to observe the amount poured out during and after the extrusion process.

[0019] Referring to Figure 2 , the lid for the viscous liquid bottle includes an inner lid 2 and an elastic valve structure member 5. The inner lid 2 is connected to the inner wall of the bottle body 1 by interference fit. Its design ensures that the viscous food can be smoothly extruded while maintaining the aesthetic appearance. The inner lid 2 is in the form of an annular gasket structure, and an annular groove 3 is provided in the inner ring of the annular gasket. The turned-out edge of the elastic valve structure member 5 is snap-fitted and fixed in the annular groove 3. The design of the annular groove 3 reduces the assembly difficulty, and reduces the risk of extrusion deformation and liquid leakage by transmitting the load. The material of the elastic valve structure member 5 is food-grade silica gel, and the middle part is recessed downward into the bottle body 1, and can cooperate with the semi-rigid or flexible bottle body 1 to bulge outward when being extruded. Its main function is to control the amount of food poured out and keep it sealed when not in use to prevent food leakage. A cut 4 is provided in the center of the elastic valve structure member 5. The cut 4 can ensure the stability of extrusion and sealing, and better control the quantitative outflow. An outer lid 6 is also provided outside the inner lid 2. The outer lid 6 is sleeved outside the inner lid 2 and is connected to the external thread on the bottle body 1. Its main function is to protect the inner lid 2 and the elastic valve structure member 5 from external damage and extend the service life at the same time.

[0020] Referring to Figure 2 , the diameter of the elastic valve structure member 5 is 13 mm, which takes into account both aesthetics and economy while facilitating the extrusion of viscous liquid. The annular groove 3 is provided at 0.1 mm from the outermost side of the outer diameter, which can avoid the risks of difficult assembly, extrusion deformation, resulting in the opening of the cut 4 and loss of sealing performance and liquid leakage, as well as excessive clearance of the valve seat and failure to meet the requirements of tight fit. The concave surface of the elastic valve structure member 5 is a curved surface, the convex surface center part is set as a flat surface, and the central thickness is 0.4 mm, which can have good flow control effect and sealing performance.

[0021] Referring to Figure 3 , a 6.5*6.5 mm 4Y cross-shaped cut 4 is adopted in the center of the elastic valve structure member 5. Combining with the food-grade silica gel used for the elastic valve structure member 5, good flow control effect and sealing performance can be achieved.

[0022] The working principle of the embodiment of the present application is as follows: The elastic valve structure 5 is placed and fixed in the annular groove 3 of the inner cover 2, and the inner cover is fixedly connected through the interference fit of the support platform 7 and the bottle body 1. When in use, the user only needs to gently squeeze the bottle body 1, and the viscous food will be smoothly extruded through the incision 4 of the elastic valve structure 5. The design of the incision 4 ensures the quantitative outflow of the food. During and after use, the user can also observe the upper scale 8 and the lower scale 9 on the bottle body 1 to determine the amount poured out. When not in use, the elastic valve structure 5 remains sunken in its natural state to ensure the sealing of the bottle mouth and prevent the food from leaking when the bottle is tilted or shaken. After use, the user can disassemble the elastic valve structure 5 and replace it with different sizes for bottles with different calibers. The outer cover 6 can also be sleeved outside the inner cover 2 and threadedly connected to the bottle body 1 to keep the bottle mouth clean.

[0023] Through these designs and usage methods, the utility model not only improves the user experience, but also ensures the practicability and reliability of the product.

[0024] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
