Detailed Description

The invention is further elucidated with reference to the drawing.

Referring to fig. 1, an embodiment of the present invention is an all-plastic vacuum cream bottle with a simple structure, which includes a bottle body 1, a bottle cap 2 mounted on the upper portion of the bottle body 1, a threaded connection between the bottle cap 2 and the bottle body 1, and a sealing ring 12 mounted between the bottle cap 2 and a pressing cap 5 for improving the sealing performance therebetween. More importantly, as shown in fig. 2 and 3, a pump cover 3 is further installed between the bottle body 1 and the bottle cover 2, the pump cover 3 is a key component of the vacuum cream bottle, specifically, a through hole 4 is additionally arranged on the pump cover 3, and then after the pump cover 3 is installed on the bottle body 1, the through hole 4 is communicated with the inner cavity of the bottle body 1; in addition, a press cover 5 is also required to be arranged above the pump cover 3; it should be noted that a gap is required to be maintained between the press cover 5 and the pump cover 3, one side of the press cover 5 is provided with a fluid outlet 6, the fluid outlet 6 is provided with a first one-way valve 10, the other side of the press cover 5 is provided with a bulge 7, the bulge 7 is a pressing position when the vacuum cream bottle is used, and the fluid outlet 6 is also required to be communicated with the gap between the press cover 5 and the pump cover 3 so as to generate air pressure; corresponding to the structure for generating air pressure, a piston body 8 is further installed inside the bottle body 1, the side surface of the piston body 8 is in close contact with the inner wall of the bottle body 1, the piston body 8 is made of flexible rubber materials, and an air inlet is additionally arranged at the bottom of the bottle body 1. Preferably, in order to ensure the aesthetic property and the production and assembly of the vacuum cream bottle, the bottle cap 2 and the bottle body 1 are both designed to be cylindrical, that is, the outer contour of the cross section of any one of the bottle cap 2 and the bottle body 1 is circular.

With the structure, when the bulge on the pressing cover 5 is manually pressed, the liquid in the bottle body 1 can be pumped out from the fluid outlet 6, and the pressing cover 5 is not required to be reset by using a metal spring; the pump cover 3 and the press cover 5 are installed at the opening at the upper part of the bottle body 1, air pressure is generated in the space between the pump cover 3 and the press cover 5 after the press cover 5 is pressed down, liquid in the bottle body 1 is pumped out by utilizing the air pressure under the matching action of the piston body 8, then the press cover is reset under the action of the one-way valve, so that a reset spring is saved, liquid discharging and resetting can be completed by utilizing the resilience force of plastics, and deterioration caused by contact of the liquid in the bottle and a metal spring is avoided.

In order to facilitate the improvement of the structural integrity of the vacuum cream bottle, in another embodiment of the present invention, a bottom cap 9 may be further installed at the lower portion of the bottle body 1, and the bottom cap 9 may be installed in such a manner that the upper portion thereof is inserted into the circumferential groove at the lower portion of the bottle body 1; as another installation mode of the bottom cover 9, a gap can be additionally arranged between the inner wall and the outer wall of the bottle body 1, namely, an interlayer is additionally arranged between the inner wall and the outer wall, and then the bottom cover 9 is embedded into the gap interlayer between the inner wall and the outer wall, the installation mode and the principle are basically the same as those of the annular groove, after the gap interlayer is additionally arranged between the inner wall and the outer wall of the bottle body 1, the sealing performance of liquid storage in the bottle body 1 can be further improved, and the phenomenon that the bottle body is damaged due to collision during use and the liquid pumping function of the air pressure is influenced can also be.

Furthermore, in order to further improve the sealing performance in use, a second one-way valve 11 can be further installed on the through hole 4 on the pump cover 3, and the direction of one-way blocking of the second one-way valve 11 and the first one-way valve 10 is opposite, so that the liquid is pumped out, and the sealing performance in a non-use state is further improved.

According to another embodiment of the present invention, in this embodiment, in order to facilitate the gap between the pump cover 3 and the pressing cover 5 to generate the air pressure, a concave position corresponding to the positions of the fluid outlet 6 and the protrusion 7 may be provided on the upper portion of the pump cover 3, so as to increase the space of the gap between the pump cover 3 and the pressing cover 5, thereby facilitating the pressure generated by pressing the pressing cover 5.

It should be noted that the pressing cover 5 and the pump cover 3 can be made of any plastic, and the vacuum cream bottle has a small pressing range in the using process, and is generally disposable, so the toughness and strength of the plastic material are not considered too much.

Referring to fig. 1, 2 and 3, in practical use, in the above preferred embodiment of the present invention, the mounting structure of the all-plastic vacuum cream bottle is as shown in fig. 1, when the bottle is filled with liquid and occupies the space inside the bottle body 1, when the liquid inside the bottle body 1 needs to be used, the protrusion 7 on the pressing cover 5 is manually pressed down to compress the air in the gap between the pressing cover 5 and the pump cover 3, the air is discharged from the fluid outlet 6, the pressing cover 5 is reset after the protrusion 7 is released, at this time, under the action of the first one-way valve 10, the external air cannot enter from the fluid outlet 6 any more, so that the liquid inside the bottle body 1 is sucked into the gap between the pressing cover 5 and the pump cover 3 under the action of the re-air pressure, and after the protrusion 7 on the pressing cover 5 is continuously pressed and reset, the pressure in the gap between the pressing cover 5 and the pump cover 3 is greater than the sealing pressure of the first one-way valve 10, liquid is discharged from the fluid outlet 6; in the above process, since the sealing direction of the second check valve 11 is opposite to that of the first check valve 10, the liquid can be smoothly sucked into the gap between the pressing cover 5 and the pump cover 3 from the inner cavity of the bottle body 1 under the action of the pressure, and then the liquid is discharged by breaking through the pressure of the first check valve 10. And the liquid in the bottle body 1 is gradually reduced by the pressure, and the piston body 8 is lifted along with the reduction, so that the pressure can continuously press the liquid in the bottle body 1 out.
