Description

Technical Field

[0001] This utility model relates to the field of packaging containers, specifically to a lid connection structure for a sports water bottle, which is equipped with a silicone valve for distributing fluid and controlling flow. Background Technology

[0002] Sports water bottles are portable hydration tools designed specifically for sports activities. They typically need to be lightweight, leak-proof, and easy to operate with one hand, and are commonly used in activities such as fitness, running, and cycling. Their core function is to quickly replenish fluids while adapting to high-frequency use and complex environments. Traditional sports water bottles mostly adopt an open-mouth direct-drinking or open-sip design, and some products are equipped with straws or valve structures to improve drinking convenience and sealing.

[0003] However, while existing technologies can generally meet the needs of daily exercise, significant shortcomings still exist in high-intensity or special exercise scenarios. For example, when consumers urgently need to rehydrate after strenuous exercise, they often choke due to drinking too much water too quickly; when the bottle is tilted or shaken, the liquid is prone to spillage due to failure of the sealing structure or unstable flow rate, causing safety hazards or waste. Summary of the Invention

[0004] The purpose of this utility model is to provide a lid connection structure for a sports water bottle, so that users can accurately control the amount of water they drink when using this type of sports water bottle.

[0005] This utility model adopts the following technical solution: a lid connection structure for a sports water bottle, including a combination ring fastened to the top surface of the bottle body, a valve seat provided inside the combination ring, an annular groove provided on the inner circumference of the valve seat, an elastic valve with a convex surface facing the inside of the bottle body provided at the center of the valve seat, the edge of the elastic valve being engaged with the annular groove, a support platform that is interference-fitted between the valve seat and the combination ring, a straw connected to the sports water bottle provided below the support platform, and liquid flowing sequentially through the straw, support platform, valve seat and elastic valve along the drinking direction.

[0006] As a preferred technical solution, the outer periphery of the resilient valve is provided with a flange that adapts to the annular groove. In the above technical features, the resilient valve, through the tight fit between the flange and the annular groove, can effectively transfer loads, improve the stability of the resilient valve on the valve seat, reduce or avoid the risk of the resilient valve falling off the valve seat, and ensure the sealing between the resilient valve and the valve seat.

[0007] As a preferred technical solution, the thickness of the elastic valve gradually decreases radially from the center outwards.

[0008] As a preferred technical solution, the central part of the convex surface of the elastic valve is a plane, and the edge of the plane transitions to the edge through an arc surface.

[0009] As a preferred technical solution, the thickness of the central portion of the elastic valve is 0.3-0.4 mm. Through the above technical features, the shape of this elastic valve facilitates liquid backflow, reduces the risk of backflow and residue, and ensures that the elastic valve structure has good elasticity, thereby better cooperating with the extrusion of the bottle and achieving better extrusion stability.

[0010] As a preferred technical solution, the elastic valve is made of silicone and includes a slit in the middle. The slit opens under liquid pressure when there is liquid flowing inside the elastic valve and closes automatically due to elasticity when there is no liquid flowing.

[0011] As a preferred technical solution, the cut includes one of a cross-shaped, star-shaped, or Y-shaped cut, with the outer diameter of the cut circle being 3-4 mm. These technical features facilitate timely rebound of the elastic valve structure during the extrusion process, resulting in better control of the metered outflow.

[0012] As a preferred technical solution, the straw is inserted into the lower part of the valve seat and is interference-fitted therewith, and a gravity ball is provided at the bottom of the straw. These technical features allow liquid at the bottom of the kettle to be smoothly drawn out.

[0013] Here, the gravity ball refers to the counterweight structure at the bottom of the straw. It can have a through hole connecting to the inside of the straw, or it can be integrally connected to the outer wall of the straw.

[0014] As a preferred technical solution, the system also includes an outer cover fitted around the valve seat, the outer cover being threadedly connected to the water bottle body. These technical features effectively protect the valve seat body and the elastic silicone valve structure from external damage.

[0015] As a preferred technical solution, the bottle body is transparent and has graduation lines on it. This technical feature allows consumers to easily see the amount consumed and the remaining amount during the drinking process.

[0016] The advantages and beneficial effects of this invention are as follows: the elastic valve allows users to precisely control the amount inhaled during drinking, avoiding choking due to excessive flow and keeping the bottle opening clean, thus reducing cleaning work; the elastic valve is recessed into the bottle body in its natural state, and the support platform and combination ring fix the valve seat to the bottle body, ensuring that the container is sealed when not in use; the annular groove design on the valve seat body makes it easier to fix the elastic silicone valve structure, avoiding the risk of compression deformation and leakage.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0022] Example 1 Please see Figures 1-3 This embodiment provides a lid connection structure for a sports water bottle, including a combination ring 2 that snaps onto the top surface of the bottle body 1. The combination ring 2 has a valve seat 3 inside, and an annular groove 4 is provided on the inner circumference of the valve seat 3. An elastic valve 5 facing inwards is located at the center of the valve seat 3, and the edge of the elastic valve 5 is engaged with the annular groove 4. A support platform 7, which is interference-fitted between the valve seat 3 and the combination ring 2, is also provided between them. A straw 8, which connects to the sports water bottle, is located below the support platform 7. Along the drinking direction, the liquid flows sequentially through the straw 8, the support platform 7, the valve seat 3, and the elastic valve 5. The outer circumference of the elastic valve 5 has a flange 9 that adapts to the annular groove 4. The thickness of the elastic valve 5 gradually decreases radially from the center outwards. The central part of the convex surface 6 of the elastic valve 5 is a plane 10, and the edge of the plane 10 transitions to the edge through an arc surface 11. The elastic valve 5 is made of silicone, and the thickness of the central part of the elastic valve 5 is 0.3 mm. The elastic valve 5 includes a cross-shaped cut in the middle, with an outer diameter of 3mm. A straw 8 is inserted into the lower part of the valve seat 3 and is interference-fitted therewith. A gravity ball 12 is provided at the bottom of the straw 8.

[0023] Example 2 Based on Example 1, the thickness of the central portion of the resilient valve 5 is 0.4 mm. The resilient valve 5 includes a cross-shaped cut in the middle, and the outer diameter of the cut is 4 mm.

[0024] Example 3 Based on Embodiment 1, the elastic valve 5 includes a Y-shaped cut in the middle, and the bottle body 1 is a transparent body with scale lines on it.

[0025] Example 4 Based on embodiment 3, it also includes an outer cover fitted around the valve seat 3, and the outer cover is connected to the bottle body 1 by a thread 13.

[0026] The working principle of this utility model is that the liquid pressure generated by squeezing the bottle 1 pushes the elastic valve 5 to deform and open, so that the liquid flows out along the path of the straw 8, the support platform 7, the valve seat 3, and the elastic valve 5. The user can control the opening and closing degree of the cut by squeezing force to achieve precise flow adjustment. After the pressure is released, the valve closes quickly due to the elasticity of the material and the radially thinning design. At the same time, the arc surface 11 of the convex surface 6 guides the liquid backflow. Combined with the negative pressure seal formed by the valve's indentation into the bottle when it is static, it simultaneously achieves anti-choking, anti-leakage, and low residue, which not only improves the user experience but also ensures the practicality and reliability of the product.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
