Problems solved by technology

Patent CN 105923281A discloses a self-priming pump-pressed packaging bottle, which discloses the discharge principle of a general push-type discharge packaging bottle. After the paste is extruded from the discharge pipe, the upper end of the discharge pipe is closed by a pressing member. The paste hangs on the wall in the discharge pipe to block the discharge pipe to form a vacuum, so as to facilitate the smooth extrusion of the paste when it is used again. If the paste cannot be hung on the wall, the seal cannot be achieved, and the paste will break when it is used again, and it cannot be discharged normally. It needs to be pressed several times to ensure that the paste is extruded during use, which seriously affects the use effect of the packaging bottle

Embodiment 1

[0065] A vacuum-pumped packaging bottle, such as figure 1 with figure 2 As shown, it includes a pump head 1, an elastic body 8, a sealing pair, a cylindrical bottle body 12, a piston 11 and a base 13;

[0066] The pump head 1 is installed on the top of the cylindrical bottle body 12, the base 13 is installed on the bottom of the cylindrical bottle body 12, the piston 11 is installed at the bottom of the cylindrical bottle body 12, and the elastic body 8 is fixed on the bottom of the cylindrical bottle body 12. The upper part, the sealing pair is fixed in the middle part between the piston 11 and the elastic body 8 in the cylindrical bottle body 12; the discharge pipe 7, the elastic body 8 and the sealing pair form a closed discharge chamber (cavity 1), and the sealing pair , the piston 11 and the cylindrical bottle body 12 form a closed material storage chamber (chamber II);

[0067] The sealing pair is mainly composed of a sealing seat 9 and an elastic sealing sheet 10 fix...

Embodiment 2

[0088] A vacuum-pumped packaging bottle, which is basically the same as Embodiment 1, except that the shape of the through hole c in the pump head and the cover body, the through hole c is similar to the shape of a truncated cone, and the difference between it and the shape of a truncated cone is that the busbar It is an arc, and its one-way valve is a flip valve, such as Figure 7-10 As shown, the cover body is a spherical structure, and a part of the cover body cut with a plane has the same shape and size as the through hole c.

Embodiment 3

[0090] A vacuum-pumped packaging bottle, which is basically the same as Embodiment 1, except that the pump head, as shown in Figure 26, is not provided with a cross valve, but only with a flip valve.

Abstract

The invention relates to a vacuum-pumped packaging bottle, which comprises a pump head and an elastic body. A discharge pipe is arranged in the pump head, and two through holes arranged in sequence along the discharge direction and close to each other are arranged in the discharge pipe, and the two through holes are connected together. One-way connected one-way valve, the fluid in the discharge pipe can only flow from the end of the one-way valve far away from the discharge port to the end close to the discharge port. The elastic body is mainly composed of a pressing cylinder, a telescopic cylinder and an annular connecting piece. Both ends of the tube are open, and the two open ends located on both sides of the connecting piece and close to each other are respectively connected with the inner ring and outer ring of the connecting piece. The hollow discharge cylinder has a plurality of discharge openings on the side wall of the hollow discharge cylinder. The parts in the vacuum-pumped packaging bottle of the present invention are compact and reliable, firmly connected, not easy to fall off during use, simple in structure, convenient in operation, can automatically cut off the paste, prevent paste backflow, and have good vacuum sealing performance.

Description

technical field [0001] The invention belongs to the packaging field and relates to a vacuum pumping packaging bottle, in particular to a vacuum pumping packaging bottle with a pump head containing a one-way valve. Background technique [0002] With the development of society, people's material life has been greatly enriched. People not only have the pursuit of product quality, but also put forward higher requirements for the appearance and packaging of products, especially the packaging of daily necessities. Its appearance packaging is not only a simple container, but also must take into account the beautiful shape and the convenience of use. Squeeze-type or push-type packaging bottles stand out in the packaging of daily necessities because of their convenience and beautiful appearance. [0003] Although the push-type packaging bottle can take into account the beautiful shape and the convenience of use, it puts forward higher requirements for processing accuracy and process...
