[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this embodiment discloses a press-type cream bottle, including an outer bottle body 1, a cap 2, a thin film inner liner 3, a dispensing head 4, and a pump body 5.

[0022] like Figure 1 and Figure 2 As shown, the cap 2 is fixed to the upper part of the outer bottle body 1. Specifically, the cap 2 includes a platform 21 and a first annular rib 25, and a slot 26 is formed between the platform 21 and the first annular rib 25. The outer bottle body 1 includes a bottle mouth 11. The inner wall of the first annular rib 25 is fastened and fixed to the outer wall of the bottle mouth 11, and the bottle mouth 11 is inserted into the slot 26 for limitation.

[0023] The inner film liner 3 is fixedly connected to the lower part of the cap 2. Specifically, the platform 21 is inserted into the inner film liner 3, the inner wall of the inner film liner 3 is heat-fused to the side wall of the platform 21, and the top of the inner film liner 3 and the slot 26 are heat-fused to each other. The inner film liner 3 is made of plastic film. The heat-fusion connection can effectively ensure the sealing performance of the connection. A storage cavity 31 is formed between the inner film liner 3 and the cap 2. The material is stored in the storage cavity 31. The inner film liner 3 is located inside the outer bottle body 1. The outer bottle body 1 includes an air hole 12 that communicates with its interior. The air hole 12 is located at the bottom of the outer bottle body 1. The cap 2 includes a first mounting groove 22. The pump body 5 is fixed to the first mounting groove 22. The lower end of the pump body 5 is located in the first mounting groove 22 and the upper end is connected to the discharge head 4. The pump body 5 is a prior art technology and is used to pump the material in the storage cavity 31 out. Press the discharge head 4 to make the storage cavity 31 communicate with or block the upper surface of the discharge head 4.

[0024] During the pressing and discharging process, the pressure inside the storage chamber 31 will gradually decrease. Since the outside of the film inner liner 3 is connected to the outside through the air hole 12, the external air pressure will squeeze the film inner liner 3, causing the film inner liner 3 to shrink. Therefore, the pressing and pumping of material can be achieved without the need for a plastic inner liner and piston. This not only has good reliability but also lower manufacturing cost.

[0025] Furthermore, the upper part of the bottle opening 11 abuts against the lower surface of the film liner 3 located at the top of the slot 26, as shown in the image. Figure 2 As shown, the cooperation between the bottle opening 11 and the film liner 3 further ensures the reliability of the seal between the film liner 3 and the cap 2 at the top of the slot 26.

[0026] like Figure 1 and Figure 2 As shown, it also includes an inner cover 9, which includes a third annular rib 91 and a fourth annular rib 92. The third annular rib 91 is fixedly connected to the outer wall of the first annular rib 25. The inner wall of the fourth annular rib 92 is provided with a second annular platform 93. The cover 2 includes a second annular rib 28 located on the upper part of the platform 21. The inner wall of the discharge head 4 is sleeved on the outside of the second annular rib 28. The discharge head 4 is inserted into the gap between the second annular rib 28 and the second annular platform 93. The discharge head 4 includes a first annular platform 42. An elastic element is sleeved on the outside of the second annular rib 28. The upper end of the elastic element abuts against the lower part of the first annular platform 42 and the lower end abuts against the upper part of the platform 21. The upper part of the first annular platform 42 can abut against or disengage from the lower part of the second annular platform 93. By setting the inner cover 9, the discharge head 4 can be installed and limited. When the discharge head 4 is pressed down, the elastic element will be compressed. When the discharge head 4 is released, the discharge head 4 can move upward and reset due to the elastic force of the elastic element.

[0027] The elastic element is a metal spring or a silicone spring. In this embodiment, a silicone spring, i.e., a silicone ring 7, is preferred. Generally, a second mounting groove 27 is provided on the outer side of the second annular rib 28, and a silicone ring 7 is sleeved on the outer wall of the second annular rib 28. The lower end of the silicone ring 7 abuts against the bottom of the second mounting groove 27, and the upper part of the silicone ring 7 abuts against the lower part of the first annular platform 42. The silicone ring 7 includes a plurality of annular cavities 71 arranged along its height direction. When the discharge head 4 is pressed down, the annular cavity 71 will be compressed. When the discharge head 4 is released, the annular cavity 71 will recover its deformation, thereby driving the discharge head 4 to rise.

[0028] like Figure 1 As shown, it also includes an outer cover 6, which covers the discharge head 4. The outer cover 6 is fastened to the second annular rib 28. By setting the outer cover 6, the discharge head 4 can be protected.

[0029] like Figure 1 and Figure 3As shown, a water-sealing sheet 8 is fixed in the first mounting groove 22. The water-sealing sheet 8 is a silicone sheet. The water-sealing sheet 8 and the pump body 5 form an internal cavity 24. The storage cavity 31 and the internal cavity 24 are connected or blocked by the water-sealing sheet 8. Specifically, the cover 2 includes a feed hole 23 located at the lower part of the first mounting groove 22. The feed hole 23 is connected to the storage cavity 31. The water-sealing sheet 8 is located above the feed hole 23. The water-sealing sheet 8 includes multiple through holes 81. The through holes 81 are located on the outer periphery of the feed hole 23 and can abut the bottom of the first mounting groove 22 at their lower part. The feed hole 23 and the internal cavity 24 are connected by the through holes 81. The discharge head 4 includes a discharge port 41. The discharge port 41 and the internal cavity 24 are connected or blocked by the pump body 5.

[0030] After normal use, the cream bottle will have residual material in both the outlet 41 and the inner cavity 24. When dispensing is not needed, the lower part of the through hole 81 abuts against the bottom of the first mounting groove 22. At this time, the storage cavity 31 and the inner cavity 24 are blocked, and the outlet 41 and the inner cavity 24 are also blocked by the pump body 5, thereby effectively improving the storage effect of the material in the storage cavity 31. When the dispensing head 4 is pressed, the bottom of the sealing plate 8 will arch upward and deform. At this time, the through hole 81 will disengage from the bottom of the first mounting groove 22, and the storage cavity 31 and the inner cavity 24 will be connected through the through hole 81, and the material in the storage cavity 31 will be replenished into the inner cavity 24.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
