Description

New double-sealed bottle

technical field

The utility model relates to the technical field of bottles, in particular to a novel double-sealed packaging bottle.

Background technique

After the liquid container bottle is poured, the residual liquid at the bottle mouth is easy to flow back to the outside of the bottle body along the outside of the bottle mouth, which not only causes liquid waste, but also pollutes the outer surface of the bottle. In order to solve the above problems, those skilled in the art have designed a bottle cap that can recycle backflow liquid. For details, please refer to the "leak-proof bottle cap structure" with the patent number "201020118166.0". In this patent, the lower sleeve is provided with a return hole between the inner thread and the protruding ring to realize liquid recovery, and the upper bottle cap body is screwed with the lower sleeve. However, in the process of using the liquid container bottle with the above bottle cap, if the bottle body falls to the ground, the liquid will flow into the upper bottle cap body from the liquid outlet of the lower sleeve. If the upper bottle cap body is opened at this time, the liquid will easily flow from the top. The bottle cap body flows out and flows back to the outside of the upper bottle cap body, polluting the outer surface of the upper bottle cap body.

Detailed ways:

In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below with reference to the implementation cases and accompanying drawings. The utility model can be implemented in the following ways:

1-8, the new double-sealed packaging bottle includes a bottle body 1 and a bottle cap. The bottle cap includes an outer cap 2 that is screwed with the bottle body 1, and an inner cap 3 that returns the liquid to the bottle body 1. . The bottle body 1 and the outer cover 2 are threadedly connected, that is, the bottle neck of the bottle body 1 is provided with a thread, and the inner side of the outer cover 2 is provided with a thread compatible with the thread of the bottle body 1; Unscrew with the bottle body 1, and the liquid can be discharged.

The inner cover 3 is detachably installed at the bottle mouth of the bottle body 1; because the bottle body 1 has many models and specifications, and the shape of the inner cover 3 is relatively complex, if the inner cover 3 and the bottle body 1 are integrally formed, Not only the cost of opening the mold is high, but also the defect rate is high; the method of inserting the inner cover 3 into the bottle mouth and exiting greatly reduces the cost of opening the mold of the bottle body 1, and the installation is simple and quick; and when one of the inner cover 3 or the bottle body 1 is used If there is any defect, just replace the defective inner cap 3 or bottle body 1, so as to avoid scrapping the whole packaging bottle and reduce scrapping cost.

The inner cover 3 is provided with an outer port 31 and an inner port 32, the inner port 32 is higher than the outer port 31; a concave annular return groove 33 is formed between the outer port 31 and the inner port 32. 33 is provided with a return port 34 communicating with the bottle body 1 . The bottom of the inner cover 3 is inclined toward the end where the return port 34 is located. After the liquid in the bottle body 1 flows out from the inner port 32, the liquid remaining on the outer wall of the inner port 32 flows into the return tank 33, and collects at the return port 34 and flows back into the bottle body 1, thereby reducing the waste of liquid.

An annular inner plug 21 protrudes downward from the top inner wall of the outer cover 2 , and a side sealing line 22 that fits with the end surface of the inner cover 3 extends downward from the corner of the outer cover 2 . After the bottle cap and the bottle body 1 are screwed tightly, the inner wall surface of the annular inner plug 21 is in contact with the outer wall surface of the inner port 32 , and the side sealing line 22 abuts the end surface of the outer port 31 . When the outer cap 2 and the bottle body 1 are screwed tightly, the annular inner plug 21 of the outer cap 2 is inserted between the outer opening 31 and the inner opening 32 of the inner cap 3, so that the inner wall surface of the annular inner plug 21 is connected to the outer surface of the inner opening 32. The wall surface is attached; after screwing, the side end sealing line 22 of the outer cover 2 cuts into the end face of the outer port 31 of the inner cover 3, so that a double sealing effect is achieved between the outer cover 2 and the inner cover 3, effectively preventing the liquid from the bottle cap. Outflow, good sealing effect. Several reinforcing ribs 23 are arranged between the annular inner plug 21 and the side end sealing line 22, which can avoid the deformation of the annular inner plug 21 and the side end sealing line 22 and increase the strength of the joint surface.

The top of the inner cover 3 is provided with an annular protrusion 35 that is clamped with the bottle mouth, so as to facilitate the installation and removal of the inner cover 3 . A plurality of limit blocks 36 are arranged below the annular protrusion 35 to limit the rotation and displacement of the inner cover 3 at the bottle mouth. The top of the inner surface of the bottle mouth is provided with a limit concave portion 11 adapted to the limit blocks 36. . When inserting the inner cap 3 into the bottle mouth, insert the limiting block 36 into the limiting concave portion 11 of the bottle mouth, which can prevent the inner cap 3 from rotating at the bottle mouth. The bottom of the inner cap 3 is provided with an inclined surface 37 which is convenient for inserting the inner cap 3 into the bottle mouth. This design can facilitate the insertion of the inner cap 3 .

The packaging bottle of the utility model can not only recover the backflow liquid, but also prevent the liquid from backflowing from the outer side of the outer cover mouth to the outer side of the outer cover when the packaging bottle falls to the ground and unscrewed, and the sealing effect is good.

Finally, it should be noted that: the above is only the preferred embodiment of the present utility model, and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model , should be included within the protection scope of the present invention.
