A cup lid with an improved pressing structure

Abstract

This utility model discloses an improved press-fit cup lid, including a cup lid holder, a first sealing ring, a cup lid base, a second sealing ring, a pressure relief valve, a cup lid fixing seat, a cup lid buckle, a fixing seat bracket, a fixing seat outer ring, a top cover, a cup lid opening button, a fixing buckle, connecting threads, and mounting holes. The cup lid holder is internally and fixedly connected to the cup lid base and the cup lid fixing seat, with the first sealing ring fitted onto the cup lid base. This utility model features a pressure relief valve structure that automatically releases pressure when the pressure inside the cup is too high, preventing the cup lid from popping out or liquid from spraying out due to pressure accumulation. Simultaneously, it maintains a certain level of sealing in conjunction with the sealing ring, preventing liquid leakage during normal use and enhancing safety performance. Furthermore, its modular design facilitates disassembly and cleaning, as well as maintenance or replacement of damaged parts, significantly reducing operating costs, improving product durability, and extending the overall lifespan of the cup lid.

Description

Technical Field

[0001] This utility model relates to the field of cup lid technology, and in particular to a cup lid with an improved pressing structure. Background Technology

[0002] A press-type cup lid is an ingeniously designed and easy-to-use accessory for drinking devices, widely used in various beverage containers such as insulated cups, kettles, and coffee cups. This type of lid uses a specific pressing mechanism to control the flow and sealing of liquids, providing users with a more flexible and hygienic drinking experience.

[0003] In applications, existing press-type cup lids lack an effective pressure relief mechanism when pressure accumulates in the cup, making the lid prone to loss of control under pressure, which can easily cause the lid to pop out or liquid to spray out. In addition, the overall design of traditional press-type cup lids tends to be integrated, with tight and complex connections between components, making it difficult for users to easily disassemble them when cleaning or maintenance is needed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an improved press-fit cup lid, including a cup lid holder, a cup lid base and a cup lid fixing seat are fixedly connected in the cup lid holder, a first sealing ring is sleeved on the cup lid base, an installation hole is opened on the cup lid base, a pressure relief valve is provided in the installation hole, a second sealing ring is sleeved on the pressure relief valve, a first pressure relief vent plug and a second pressure relief vent plug are provided on one side of the pressure relief valve, and the first pressure relief vent plug and the second pressure relief vent plug are located inside the pressure relief valve.

[0006] As a further technical solution of this utility model, the cup lid holder is threadedly connected to a fixing seat outer ring, a fixing seat bracket is provided inside the fixing seat outer ring, and a cup lid buckle is fixedly connected to the fixing seat bracket.

[0007] As a further technical solution of this utility model, a first slot is provided on the cup lid fixing seat at the position corresponding to the cup lid buckle, and the cup lid buckle is engaged in the first slot.

[0008] As a further technical solution of this utility model, a top cover is fitted onto the outer ring of the fixing seat.

[0009] As a further technical solution of this utility model, a fixing buckle is provided on one side of the outer wall of the top cover, and the fixing buckle is engaged with the cup lid fixing seat.

[0010] As a further technical solution of this utility model, a second slot is provided on the cup lid fixing seat, and the cup lid base is engaged with the second slot.

[0011] As a further technical solution of this utility model, a cup lid opening button is sleeved on the top cover.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model is designed with a pressure relief valve structure, which can automatically release pressure when the pressure inside the cup is too high, preventing the cup lid from popping out or the liquid from spraying out due to pressure accumulation. At the same time, it works with a sealing ring to maintain a certain degree of sealing, preventing liquid leakage during normal use, thus enhancing safety performance. Furthermore, the modular design facilitates disassembly and cleaning, and also makes it easy to repair or replace damaged parts, greatly reducing usage costs, improving product durability, and extending the service life of the entire cup lid.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see the appendix Figure 1 -Appendix Figure 3 This utility model provides an embodiment of an improved press-fit cup lid, comprising a cup lid holder 1, a cup lid base 3 and a cup lid fixing seat 8 fixedly connected within the cup lid holder 1, a first sealing ring 2 sleeved on the cup lid base 3, an installation hole 18 on the cup lid base 3, a pressure relief valve 5 disposed within the installation hole 18, a second sealing ring 4 sleeved on the pressure relief valve 5, a first pressure relief vent plug 6 and a second pressure relief vent plug 7 disposed on one side of the pressure relief valve 5, and the first pressure relief vent plug 6 and the second pressure relief vent plug 7 disposed within the pressure relief valve 5; a fixing seat outer ring 11 is threadedly connected to the cup lid holder 1, and a fixing seat bracket 10 is disposed within the fixing seat outer ring 11, for fixing... A cup lid clip 9 is fixedly connected to the support bracket 10; a first slot 15 is provided on the cup lid fixing seat 8 at the position corresponding to the cup lid clip 9, and the cup lid clip 9 is engaged in the first slot 15, which is used to fix the cup lid clip 9; a top cover 12 is sleeved on the outer ring 11 of the fixing seat, and a fixing clip 14 is provided on one side of the outer wall of the top cover 12, which is engaged in the cup lid fixing seat 8; a second slot 16 is provided on the cup lid fixing seat 8, and the cup lid base 3 is engaged in the second slot 16, which is used to fix the cup lid base 3; a cup lid opening button 13 is sleeved on the top cover 12, which is used to control the cup lid to be closed or opened.

[0020] Working principle: When using this utility model, the cup lid holder 1 is connected to the cup body. During use, by pressing the cup lid opening button 13 on the top cover 12, the cup lid opening button 13 drives the cup lid buckle 9 on the fixed base bracket 10 to move. The cup lid buckle 9 is connected to the cup lid fixed base 8 through the first slot 15. By controlling the connection or disconnection between the cup lid buckle 9 and the cup lid fixed base 8, the cup lid can be sealed or opened. During use, when the pressure inside the cup gradually accumulates to the threshold, the pressure relief valve 5 automatically opens, the second pressure relief vent plug 7 is fixed, and the first pressure relief vent... The vent plug 6 rises, allowing some gas to escape, thereby reducing the internal pressure. Once the pressure is released to a safe level, the pressure relief valve 5 automatically closes, restoring the sealing state. A spring is provided on the first pressure relief vent plug 6 to reset the first pressure relief vent plug 6 after pressure relief. The cup lid base 3 is sealed by the first sealing ring 2, and the pressure relief valve 5 is sealed by the second sealing ring 4. The fixing buckle 14 is used to fix the top cover 12, the second slot 16 is used to fix the cup lid base 3, the outer ring 11 of the fixing seat is used to fix and protect the internal components, and the mounting hole 18 is used to install the pressure relief valve 5.
