The press-type container of the present invention can squeeze out the contents in the receiving chamber by pressing the pressing seat, and the external air and impurities will not enter the receiving chamber, which is convenient for improving the shelf life of the contents; at the same time, this design can squeeze out all the contents from the container to avoid waste of the contents.

[0032] In order to ensure that the piston does not move downward when the pressing seat is pressed, it is necessary to ensure that the friction between the piston and the inner wall of the accommodating chamber 1000 is large enough so that the contents are squeezed out of the discharge tube 11 when the pressing seat is pressed; in this embodiment, the piston 5 includes a plug body 51 that slides and seals with the inner wall of the accommodating chamber 1000, and the bottom of the plug body 51 is connected to a support member 52 for preventing the piston 5 from moving downward, and the support member 52 includes a support frame 521 connected to the bottom of the plug body 51 and a spring 522 arranged on the support frame 521, and the spring 522 is in contact with the inner wall of the accommodating chamber 1000.

[0033] In order to prevent the piston from falling out from the bottom of the container body, a protrusion is provided at the bottom of the container body 1 to prevent the piston 5 from coming out from the lower opening of the container body 1 .

[0034] To ensure hygiene, in this embodiment, an outer cover 6 for closing the discharge tube 11 is provided on the upper portion of the pressing seat 2 ; similarly, the outer cover 6 may also be provided on the upper portion of the container body 1 .

[0035] In this embodiment, the reset member 3 is a plurality of reset ribs arranged on the pressing seat 2. Similarly, the reset member 3 can also be an element with elastic reset, such as a spring, arranged between the container body 1 and the pressing seat 2; the limiting member 4 is a hook arranged at the bottom of the extrusion portion 21. Example

[0036] like Figures 8 to 11 As shown, a push-type container of the present embodiment comprises a container body 1 with an upper opening, a pressing seat 2 is slidably connected to the upper part of the container body 1, a reset member 3 for driving the pressing seat 2 to reset upward is provided between the container body 1 and the pressing seat 2, a limit member 4 for limiting the maximum position of the pressing seat 2 is provided between the container body 1 and the pressing seat 2, an outlet pipe 11 penetrating the pressing seat 2 is provided on the upper part of the container body 1, the pressing seat 2 is provided with an extrusion portion 21, the extrusion portion 21 is slidably and sealedly connected to the upper part of the container body 1, and a piston 5 is slidably and sealedly connected to the bottom of the container body 1, The container body 1 is provided with an air supply pipe 7 penetrating the piston 5, one end of the air supply pipe 7 is connected to the outside, and one end of the air supply pipe 7 is connected to the bottom of the piston 5. A receiving chamber 1000 for receiving the contents is formed between the piston 5, the extrusion part 21, and the inner side of the container body 1; when a downward pressing force is applied to the pressing seat 2, the extrusion part 21 squeezes the contents in the receiving chamber 1000, so that the contents are squeezed out from the outlet pipe 11; and after the pressing force is removed, the pressing seat 2 is reset upward under the action of the reset member 3, and at the same time, the piston 5 moves upward along the inner wall of the container body 1 under the action of the outside atmospheric pressure. The press-type container of the present invention can squeeze out the contents in the receiving chamber by pressing the pressing seat, and the external air and impurities will not enter the receiving chamber, which is convenient for improving the shelf life of the contents; at the same time, this design can squeeze out all the contents from the container to avoid waste of the contents.

[0037] The difference between this embodiment and the first embodiment is that: in this embodiment, the bottom of the container body 1 is sealed, and the air pressure at the bottom of the piston is balanced by the air supply pipe, so that the piston can move upward when the pressing seat is reset upward; in this embodiment, the outer cover 6 is connected to the pressing seat in a hinged manner.

[0038] In this embodiment, the reset member 3 is a plurality of reset ribs arranged on the pressing seat 2.
