In the cosmetic industry, there are some high-end liquid products, which need to be packaged by a rigid glass bottle from the viewpoint of avoiding chemical reaction and increasing the packaging grade, so that liquid discharge cannot be realized by pressing the bottle bottom as in the above-mentioned technology.

Disclosure of Invention

Based on the above problems, the utility model provides a liquid storage bottle can remain the convenience of pressing out the liquid on the basis of having used the rigidity bottle, is fit for holding liquid such as high-end cosmetics, liquid medicine.

In order to realize the purpose of the invention, the utility model adopts the following technical scheme: a liquid storage bottle comprises a rigid bottle body and a bottle cap, wherein a sealing plug is downwards protruded on the lower side surface of the end part of the bottle cap; the device also comprises an elastic pressing pipe; the opening of the bottle body is hermetically connected with the lower end of the elastic pressing pipe; the sealing bolt is hermetically inserted into the upper end pipe orifice of the elastic pressing pipe; the sealing bolt is in an inverted cone shape with a small lower part and a big upper part, and is in interference fit with the upper end pipe orifice of the elastic pressing pipe; the bottle is also provided with a thread middle cover, the top of the thread middle cover is provided with a through hole, and the inner side wall of the thread middle cover is in threaded connection with the opening part of the bottle body; the lower end of the elastic pressing pipe is provided with a skirt part which extends outwards along the radial direction; the body of the elastic pressing pipe penetrates through the through hole of the thread middle cover, and the skirt gasket is arranged between the lower end surface of the thread middle cover and the upper end surface of the opening of the bottle body.

The liquid storage bottle designed by the technical scheme separates the bearing function and the extrusion function of the content liquid, the bearing function is completed by the bottle body made of rigid materials, and the extrusion function is realized by the elastic pressing pipe. The cross section of the bottle body can be round, regular polygonal and the like, and can be a glass bottle, a porcelain bottle and the like. The elastic pressing tube is required to have certain elasticity, and is required to have stable chemical properties, so that the reaction with the content liquid is avoided, and for example, silica gel can be selected. The lower extreme of elasticity pressure pipe and the oral area sealing connection of bottle, the connected mode is many, and the joint cup joints grafting bonding or plus other fastening structure all can, and this scheme selection is with lid connection in the screw thread. The inside wall of lid is equipped with the screw thread in the screw thread, realizes threaded connection with the bottle oral area, and the top of lid is equipped with the hole that link up in the screw thread, can supply the body of elasticity pressure pipe to pass. In this scheme, the lower extreme that the pipe was pressed to elasticity is designed for the skirt part along radial outside extension, and when lid and bottle oral area screwed up in the screw thread, the skirt part has formed the seal ring between lid lower extreme face and the body oral area up end in the screw thread, can effectually prevent the seepage. The pipe orifice of the upper end of the elastic pressing pipe and the sealing bolt of the bottle cap form interference fit, the sealing bolt is in an inverted cone shape, the pipe orifice of the upper end of the elastic pressing pipe has elasticity, interference fit can be formed, and the sealing effect is ideal. When in use, the whole liquid storage bottle is inverted, the content liquid flows into the elastic pressing pipe, the bottle cap is opened, and the elastic pressing pipe is squeezed, so that the content liquid can be squeezed out.

Preferably, a decorative ring is further arranged; the screw thread middle cover is made of plastic materials, the decoration ring is made of metal materials and is sleeved outside the side wall and above the top wall of the screw thread middle cover. In order to be convenient for being matched with the rigid bottle body opening part, the plastic material is selected as the cover in the screw thread, and when the plastic material is screwed down, the cover in the screw thread is easy to deform, so that the sealing failure is caused. The decorative ring which is tightly matched with the top wall of the top wall and is sleeved with the metal material outside the side wall of the middle cover of the thread can effectively restrain the deformation. In practical application, the aluminum material is selected more to decorate the circle, and the connection of lid in with the screw thread uses bonding or joint more.

Preferably, the body of the elastic pressing pipe is a horn-shaped rotating body with a small upper end and a large lower end; a circle of limiting ribs are arranged on the protrusions surrounding the outer side surface of the elastic pressing pipe body; the lower edge of the limiting rib is in lap joint with the upper end face of the screw thread middle cover, and the diameter of the outer edge of the limiting rib is larger than the aperture of the through hole of the screw thread middle cover. The main purpose of spacing muscle is whether cooperate the target in place with the lid in the sense of touch confirmation elasticity according to the pipe with the screw in the assembly process, also can avoid elasticity according to the pipe and retreat from the through-hole of lid in the screw when using.

On the basis of the technical scheme, the device also has a deformation structure: the side wall of the elastic pressing pipe is in a polygonal shape, can be in a regular polygonal shape, and can also be in a shape matched with the shape of the opening at the upper end of the bottle body. Since a circle can be approximately regarded as a regular polygon with infinite number of sides, the structure only adopts a polygon with finite number of sides, and the structure also should be regarded as falling in the protection scope of the scheme.

Preferably, the bottle cap is connected with the bottle head through threads. When the screw thread rotates to match, the sealing bolt is slowly pushed to advance, the elastic bottle mouth can be helped to gradually form the best sealing matching angle, the sealing effect is favorably improved, the direct impact between the sealing bolt and the elastic pressing pipe upper end pipe orifice can be reduced, and the good sealing effect can be favorably kept in long-term use.

Preferably, a circle of drip-proof ring is arranged in the upper end pipe orifice of the elastic pressing pipe; the upper end of the drip-proof ring is connected with the upper end of the inner side wall of the upper pipe orifice of the elastic pressing pipe, and the lower end of the drip-proof ring is a free end. The drip-proof ring is arranged in the pipe orifice at the upper end of the elastic pressing pipe, the lower end is a free end, when the bottle opening is inverted, liquid in the bottle tends to flow out of the bottle opening downwards under the action of gravity, pressure is formed on the drip-proof ring, the drip-proof ring deforms after being stressed, the opening of the drip-proof ring is reduced after the free end deforms, and free dripping of the liquid in the bottle can be effectively prevented. In particular, liquids of different viscosities may be matched to the appropriate free end opening size, and those skilled in the art may refer to the corresponding parameters and perform a limited number of experiments to obtain satisfactory values.

Preferably, the lower end opening of the anti-dripping ring is smaller than the upper end opening. This solution further constrains the size of the opening of the lower, free end.

Preferably, the upper end of the drip-proof ring is thicker than the lower end. The design makes the drip-proof ring easier to deform under the pressure of the upper liquid and easier to form a state of stopping the liquid from dropping.

Preferably, a gasket is further provided, the gasket being located between the skirt and the upper end surface of the body mouth. The gasket also has a resilient sealing effect and cooperates with the skirt to form a better deformed seal.

To sum up, the beneficial effects of the utility model are that: the bottle can keep the convenience of pressing liquid on the basis of using the rigid bottle body, and is suitable for containing high-end cosmetics, liquid medicine and other liquids.
