Problems solved by technology

With the improvement of people's living standards, the packaging requirements for hose products are becoming more and more refined. However, the current hose products do not have a fresh-keeping mechanism design, only the design of the paste flow channel. After squeezing and using, there will be The external air backflow and the remaining paste are sucked back, which will affect the service life of the paste in the tube body, and cannot play a role in keeping the paste in the tube body fresh, and does not consider reducing air contact and gas resistance, nor does it Consider Multiple Choice Interchangeable Designs

Embodiment 1

[0042] Such as Figure 1 to Figure 8 As shown, this embodiment provides a fresh-keeping hose for packaging, which can be one of composite hose, extruded hose, blown hose and aluminum hose, which includes a tube body 1, Connect the cover 2, the cover mouth 3, the first one-way valve assembly 4 and the second one-way valve assembly 5, and the tube body 1 is equipped with a cosmetic paste, which can be a paste with active ingredients or an inert The paste of the ingredients; the connecting cap 2 is arranged at the top outlet of the tube body 1, the second one-way valve assembly 5 is arranged on the connecting cap 2, and the first one-way valve assembly 4 is arranged on the second one-way valve assembly 5 Above, the cap mouth 3 is arranged on the connection cap 2 and the second one-way valve assembly 5 , and the bottom feed port of the cap mouth 2 is connected with the first one-way valve assembly 4 .

[0043] In this embodiment, under the action of pressing pressure, the paste i...

Embodiment 2

[0052] Such as Figure 14 ~ Figure 15 As shown, the discharge opening at the top of the cover nozzle 3 in this embodiment is smaller, and the top of the cover nozzle 3 is straight, and the rest of the structure is the same as that of the embodiment 1.

[0053] In summary, the present invention is provided with a pipe body, a connecting cover, a cover nozzle, a first one-way valve assembly and a second one-way valve assembly, the connecting cover is arranged at the top outlet of the pipe body, and the second one-way valve The assembly is arranged on the connection cover, the first one-way valve assembly is arranged on the second one-way valve assembly, the cover mouth is arranged on the connection cover and the second one-way valve assembly, and the bottom feed port of the cover mouth is connected with the first one-way valve assembly. The two-way valve assembly is connected. Since the first one-way valve assembly and the second one-way valve assembly are used, they need to be ...

Abstract

The invention discloses a packaging fresh-locking hose and a paste extrusion method. The hose comprises a hose body, a connecting cover, a cover nozzle, a first one-way valve assembly and a second one-way valve assembly, the connecting cover is of a split structure and is arranged at a top discharging opening of the hose body, and the second one-way valve assembly is arranged on the connecting cover, the first one-way valve assembly is arranged on the second one-way valve assembly, the cover nozzle is arranged on the connecting cover and the second one-way valve assembly, and a feeding port in the bottom of the cover nozzle is connected with the first one-way valve assembly. By blocking air, residual paste flows back into the hose body, and therefore the effect that a user can conveniently use the paste in the hose body for preservation next time is achieved.

Description

technical field [0001] The invention relates to a hose, in particular to a freshness-preserving packaging hose and a paste extrusion method, belonging to the technical field of hose packaging. Background technique [0002] At present, there are all kinds of hoses on the market, and the hoses can realize the packaging of cosmetic pastes. With the improvement of people's living standards, the packaging requirements for hose products are becoming more and more refined. However, the current hose products do not have a fresh-keeping mechanism design, only the design of the paste flow channel. After squeezing and using, there will be The external air backflow and the remaining paste are sucked back, which will affect the service life of the paste in the tube body, and cannot play a role in keeping the paste in the tube body fresh, and does not consider reducing air contact and gas resistance, nor does it Consider multiple options for interchangeability designs. Contents of the ...
