[0001] The utility model relates to a fresh -keeping container technical field, specifically is a vacuum fresh -keeping bottle. BACKGROUND

[0002] At present, the emulsion bottle with pump head in the traditional process is used, when the quantitative emulsion is pumped out, the quantitative air will enter the bottle body through the pump core, so that the air pressure inside and outside the bottle body reaches balance again. The air and water vapor entering the bottle will fully mix with the emulsion inside. For some contents susceptible to oxidation, pollution and moisture, such as essence, chemical composition or powder, this packaging method is obviously not suitable. INVENTION CONTENTS

[0003] The utility model solves the technical problem of easy oxidation, pollution and moisture, and provides a vacuum fresh -keeping bottle.

[0004] In order to solve the above technical problem, the utility model provides a vacuum fresh -keeping bottle, which comprises a double -layer bottle body, a vacuum pump head and an upper cover, and the double -layer bottle body, the vacuum pump head and the upper cover jointly constitute a vacuum pressing bottle.

[0005] Preferably, the double -layer bottle body is composed of a hard shell blow bottle with thick outer wall and a soft blow bottle with thin inner wall.

[0006] Preferably, the soft blow bottle is directly blow molded in the hard shell blow bottle by blow molding process with the hard shell blow bottle as a cavity.

[0007] Preferably, the hard shell blow bottle and the soft blow bottle are fused and sealed at the bottle opening, and other parts are separated.

[0008] Preferably, the bottom of the hard shell blow bottle is provided with a breathable port.

[0009] Preferably, the vacuum pump head and the double -layer bottle body are tightly sealed through a sealing ring.

[0010] Preferably, the vacuum pump head is provided with a vacuum pump core.

[0011] Compared with the related art, the utility model has the following beneficial effects:

[0012] The utility model is blow molded by a novel blow molding process, and the thin soft film bag is directly blow molded in the thick wall blow bottle. When the film bag gradually appears in a vacuum state, the film bag gradually shrinks, the contents are extruded to the vicinity of the vacuum pump core, and then pumped out for use. Since the film bag is in a vacuum state throughout the process, the contents are completely isolated from air and water vapor, and are in a fresh -keeping state from beginning to end.

[0013] For the above and other objects, features and advantages of the present application, a preferred embodiment will be described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please refer to Figures 1-3 A vacuum fresh-keeping bottle, comprising a double-layer bottle body 1, further comprising a vacuum pump head 2 and an upper cover 3, the double-layer bottle body 1, the vacuum pump head 2 and the upper cover 3 together constitute a vacuum pressing bottle.

[0023] Please refer to Figures 1-3The double-layer bottle body 1 is composed of a hard shell blow bottle 11 with thick outer wall and a soft blow bottle 12 with thin inner wall.

[0024] Please refer to Figure 3 、 4 The vacuum pump head 2 and the double-layer bottle body 1 are tightly sealed through a sealing ring 22, and the vacuum pump head 2 is internally provided with a vacuum pump core 21.

[0025] The utility model discloses the specific implementation process as follows: working process: a, open the upper cover 3, press the vacuum pump head 2 first time;B, the vacuum pump core 21 draws the quantitative vacuum to the soft blow bottle 12, and the atmospheric pressure extrudes the soft blow bottle 12 through the air hole 13 at the bottom of blow bottle 11;C, under the influence of atmospheric pressure, blow bottle 12 whole shrink extrusion content to the vacuum pump core 21;D, press the vacuum pump head 2 again, and the content is extruded out of the discharge nozzle of vacuum pump head 2;E, after spring reset, the vacuum pump core 21 draws the quantitative vacuum again, and the soft blow bottle 12 is affected by atmospheric pressure, and whole shrink extrusion content to the vacuum pump core 21;F, repeat the above steps, and blow bottle 12 constantly shrink volume (such as Figure Four ), until the content is all pumped out and used up;G, during the whole process, the content of blow bottle 12 is completely isolated from the outside world, is not affected by pollution, damp and oxidation, thereby achieving the effect of fresh-keeping.

[0026] The above only is the embodiment of the utility model, and does not limit the patent range of the utility model, and equivalent structure or equivalent flow conversion that utilizes the utility model specification and attached drawing contents, or direct or indirect application in other related technical fields, all are similarly included in the patent protection range of the utility model.
