[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 As shown in the figure, this utility model discloses a pump cap structure, including a push cap 1, which has a discharge channel 2 inside, and an opening 3 at one end of the push cap 1 communicating with the discharge channel 2; a snap fastener 4, which is located at the opening 3 and connected to the push cap 1, and has a receiving cavity 5 inside the snap fastener 4; an elastic valve plate 6, which is disposed in the receiving cavity 5 for sealing the opening 3; the elastic valve plate 6 has a cut 7, which communicates with the discharge channel 2; wherein, the cut 7 has a first state and a second state, the cut 7 is closed in the first state, and the cut 7 is open in the second state to form a discharge port.

[0027] Reference Figure 1-3 As shown, in the first embodiment of this utility model, the button 1 and the buckle component 4 are made of plastic PP or PE material, and the elastic valve plate 6 is made of silicone material.

[0028] The buckle component 4 is rotatably connected to the button cap 1. In use, the buckle component 4 and the button cap 1 are fixed by snap-fit ​​or glue application.

[0029] The buckle component 4 is connected to the button cap 1 via a hinge 8. The hinge 8 has a relatively thin structure, which allows for the rotatable connection and assembly of the button cap 1 and the buckle component 4. The hinge 8 enables the integrated production of the button cap 1 and the buckle component 4, thereby improving production efficiency.

[0030] The buckle component 4 has an annular groove 9 inside, and the edge of the elastic valve plate 6 has an annular rib 10 that matches the annular groove 9, so that the buckle component 4 and the button 1 are closed; the opening of the button 1 has a connecting structure that holds the elastic valve plate 6 in place and fixes it axially.

[0031] The annular rib 10 and the annular groove 9 are connected by vertical pressing to form a tight fit, ensuring that the elastic valve plate 6 is stably embedded in the receiving cavity 5 and preventing the elastic valve plate 6 from shaking due to positional movement during use.

[0032] The buckle component 4 is fully fitted with the opening 3 of the button cap 1, and the annular connecting part 11 at the opening 3 presses against the edge of the elastic valve plate 6 to form an axial fixation, which further ensures the stability of the elastic valve plate 6.

[0033] In this embodiment of the utility model, the cut 7 is cross-shaped and located at the center of the elastic valve plate 6. It opens when pressed to pump out the material.

[0034] When the cap 1 is pressed, the material flows along the discharge channel 2 and acts on the cut 7. At this time, the cut 7 is in the second state, forming the discharge port to allow the material to be discharged for use.

[0035] When the cap 1 is no longer pressed, the elastic valve plate 6 closes the cut 7 under its own restoring force. At this time, the cut 7 returns to the first state, effectively blocking the outlet, preventing residual material from dripping, and at the same time isolating air backflow to prevent material oxidation.

[0036] Reference Figure 1-3 and Figure 5 As shown, in another embodiment of the present invention, the buckle component 4 is rotatably connected to the button cap 1; the buckle component 4 and the button cap 1 are connected by a hinge 8.

[0037] The elastic valve plate 6 and the snap-fit ​​component 4 are injection molded.

[0038] The elastic valve plate 6 is made of TPU or TPE and is connected to the snap-fit ​​component 4 by two-color injection molding or two-stage injection molding. After injection molding, the elastic valve plate 6 and the snap-fit ​​component 4 are firmly connected, ensuring the fitting accuracy between the elastic valve plate 6 and the snap-fit ​​component 4, while simplifying the production process, improving production efficiency, and reducing assembly difficulty.

[0039] Reference Figure 1-2 As shown, in another embodiment three of this utility model, the snap fastener 4 is snapped into the button cap 1; the snap fastener 4 is provided with an annular groove 9, and the edge of the elastic valve plate 6 is provided with a matching annular rib 10. The elastic valve plate 6 and the snap fastener 4 are assembled into a combination, and the combination is snapped into the button cap 1 through the snap fastener 4.

[0040] The push cap 1 is made of PP plastic, the buckle component 4 is made of PP plastic or metal, and the elastic valve plate 6 is made of silicone.

[0041] The push cap 1, the buckle component 4, and the elastic valve plate 6 are independent components.

[0042] The snap-fit ​​structure maintains the stability of the resilient valve plate 6 during transportation, drops, or vibrations, ensuring that it is not easily loosened or displaced, which helps to guarantee sealing performance and the long-term reliability and overall durability of the product.

[0043] When the buckle component 4 is closed, its inner surface forms a continuous and smooth flow channel with the inner wall of the material discharge channel 2 of the cap 1, which effectively avoids the problem of material stagnation at the turning point, which may cause blockage or secondary pollution.

[0044] This utility model discloses a washing and care container, including a container body and a press pump, and also includes the aforementioned pump cap structure, wherein the press cap 1 is connected to the container body.

[0045] The push cap 1 is fixed to the opening of the container body by a threaded or snap-fit ​​structure, and the pump rod of the press pump extends into the inside of the push cap 1.

[0046] When in use, pressing down the cap 1 drives the press pump to work, and the material impacts the elastic valve plate 6 through the discharge channel 2; the cut 7 opens under pressure to form a directional discharge port, and the material is accurately discharged along the continuous flow channel; after releasing, the pump rod returns to its original position, the cut 7 of the elastic valve plate 6 closes to isolate air, and a sealed environment is formed inside the container.

[0047] The pump cap structure is connected to the container body, and the elastic valve plate 6 is closed, which, together with the container sealing design, achieves anti-oxidation and anti-drip of the material.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
