Description

Technical Field

[0001] The utility model relates to the technical field of liquid storage bottles, in particular to an essence liquid storage bottle with an anti-leakage function. Background Art

[0002] The essence of cosmetics is generally stored in a liquid storage bottle. When using the essence, it is necessary to frequently open and tighten the bottle cap of the liquid storage bottle. After long-term use, the sealing gasket in the bottle cap will be worn and aged, affecting the storage and use of the essence. Therefore, it is necessary to replace the sealing gasket regularly. For example, the existing patent number is CN211002291U, which is a sealed essential oil bottle with strong impermeability. The way to replace the sealing gasket is that the threaded rod drives a pair of connecting rods to approach each other through a wire rope under the rotation of the rotating wheel, so that the limit block is separated from the sealing gasket, and the sealing gasket is replaced. However, the essential oil bottle needs to open a working cavity in a bottle cap of a smaller volume, install parts such as a threaded rod, a rotating wheel and a thin rope, and its process is complicated. The parts are not easy to install and replace. Even if the limit block is separated from the sealing gasket and the sealing gasket is installed deep in the bottle cap, it is not convenient to take out the sealing gasket and observe the wear of the sealing gasket. At the same time, if the bottle body is tilted, the essential oil will adhere to the bottle mouth, affecting the next use. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an essence liquid storage bottle with an anti-leakage function.

[0004] The technical solution of this utility model is as follows:

[0005] A serum storage bottle with anti-leakage function, comprising a bottle body with a bottle mouth, a bottle cap with a rubber dropper being threadedly connected to the bottle mouth, a first annular protrusion being arranged on the inner side surface of the bottle mouth, a first sealing ring matching the first annular protrusion being arranged on the upper end thereof, an annular sealing protrusion matching the first sealing ring being arranged inside the bottle cap, and the annular sealing protrusion being able to contact the upper end surface of the first sealing ring;

[0006] The inner side of the bottle mouth is also provided with an annular flow shield, the middle part of which is provided with a through hole, the tube body of the rubber-tipped dropper passes through the through hole and is located inside the bottle body.

[0007] The bottle mouth of the bottle body is used to be threadedly connected to the bottle cap and is used to fill the essence. The outer side of the bottle mouth is generally a bottle mouth with an external thread. The first annular protrusion is arranged on the inner side of the bottle mouth. The outer diameter of the first annular protrusion is smaller than the outer diameter of the bottle mouth. It is used to install the first sealing ring. The first sealing ring is installed on the first annular protrusion, which is convenient for replacing the first sealing ring and observing the wear of the first sealing ring. The first sealing ring contacts the annular sealing protrusion in the bottle cap to seal and preserve the essence in the bottle body. Compared with the prior art, the sealing gasket is arranged deep in the bottle cap, which is not convenient for observing the wear of the sealing gasket. The utility model can observe the wear and deformation of the first sealing ring every time the essence is used, thereby reducing the phenomenon that air infiltrates into the bottle due to the inability to clearly observe the wear or deformation, causing the essence to be unable to be used normally.

[0008] In order to facilitate the installation of the above-mentioned first sealing ring on the first annular protrusion and prevent it from falling off, an installation groove is circumferentially opened on the outer wall of the first annular protrusion, and the outer ring of the first sealing ring is provided with an annular mounting ring, which is clamped in the mounting groove, wherein the annular mounting ring and the first sealing ring are integrally formed.

[0009] In order to facilitate the above-mentioned annular flow shield to block the essence when the bottle body is tilted, the lower surface of the annular flow shield is set as a first inclined surface, and the first inclined surface is set downwardly from the outer side of the annular flow shield in the direction of the through hole. The first inclined surface can reduce or prevent the essence from flowing through the bottle mouth to the first sealing ring, thereby reducing the leakage of the first sealing ring due to long-term immersion.

[0010] If the essence in the bottle is full, the essence may come into contact with the bottle mouth and the first sealing ring through the annular flow shield when the essence storage bottle is poured, and may also adhere to the bottle mouth for a long time. If the bottle cap is opened directly for next use, it will lead to waste of essence. For this reason, the upper surface of the annular flow shield is set as a second inclined surface, and the second inclined surface is inclined downward from the outer surface of the annular flow shield in the direction of the through hole. In the case that the essence storage bottle is poured for a long time, before the next use, the essence storage bottle can be placed forward to allow the essence to flow back into the bottle through the second inclined surface, and then the cap can be opened for use, thereby reducing the waste or contamination of the essence at the bottle mouth.

[0011] The structure of the above-mentioned first sealing ring is that the upper end surface of the first sealing ring is an arc surface, and the annular sealing protrusion is provided with an arc groove adapted to the arc surface. The arc surface of the first sealing ring can increase the contact area with the annular sealing protrusion, thereby reducing the phenomenon of essence leakage or air infiltration into the bottle.

[0012] In order to facilitate replacement of the first sealing ring, the upper end surface of the first annular protrusion is arranged to be higher than the upper end surface of the bottle mouth, which can reduce contamination of the essence when replacing the first sealing ring.

[0013] In order to further improve the sealing effect of the essence and reduce the phenomenon of air infiltration into the bottle affecting the use of the essence, a second sealing ring is provided on the lower end surface of the bottle cap, and the second sealing ring can contact the outer surface of the bottle body.

[0014] The specific structure of the above-mentioned second sealing ring is that the lower surface of the second sealing ring is set as a sealing surface with an arc pointing downward, the outer surface of the bottle body is provided with a second annular protrusion, the upper surface of the second annular protrusion is matched with the sealing surface, and when the bottle cap is tightened, the lower surface of the second sealing ring can contact the upper surface of the second annular protrusion, and the arc-shaped sealing surface can increase the contact area with the second annular protrusion, thereby improving the sealing effect.

[0015] The through hole is arranged in such a position that the axis of the through hole is coaxial with the axis of the tube body, and the distance between the hole wall of the through hole and the outer surface of the tube body is 0.1-0.5 cm. The outer surface of the tube body will adhere to the essence, and the distance range can facilitate the taking and placing of the tube body, and can also reduce the essence on the outer wall of the tube body from touching the hole wall of the through hole, thereby reducing the waste of essence.

[0016] The cross-sectional structure of the mounting groove is that the vertical cross-section of the mounting groove is an arc shape, the vertical cross-section of the annular mounting ring is an arc shape that matches the mounting groove, the annular mounting ring is made of rubber, and the arc-shaped mounting groove facilitates the annular mounting ring to be installed in the mounting groove to prevent the first sealing ring from falling off.

[0017] The beneficial effects of the utility model are:

[0018] The first annular protrusion is arranged on the inner side of the bottle mouth, and the tube body of the rubber-tipped dropper can extend to the lower part of the bottle body through the first annular protrusion. The first sealing ring is sleeved on the first annular protrusion, which is convenient for observing the wear and deformation of the first sealing ring, and can be replaced in time, thereby reducing the air leakage and liquid leakage caused by the failure of the first sealing ring to be tightly attached to the first annular protrusion due to deformation or wear. When the bottle cap is tightened on the bottle mouth, the first sealing ring is used to be in sealing contact with the annular sealing protrusion in the bottle cap, so as to realize the sealed storage of the essence in the bottle body;

[0019] The outer side surface of the annular flow shield is fixedly connected to the inner side surface of the bottle mouth and is tightly arranged. A through hole for the tube body to penetrate is provided in the middle of the annular flow shield. The annular flow shield can block the essence in the bottle when the essence storage bottle is tipped over, reduce or prevent the essence from seeping out of the first sealing ring to the outside of the bottle body, and also prevent the essence from being contaminated when in use.

DETAILED DESCRIPTION

[0027] like Figure 1 and Figure 2 The essence liquid storage bottle with anti-leakage function shown in the figure comprises a bottle body 1 with a bottle mouth 2, a bottle cap 3 with a rubber-tipped dropper 4 is threadedly connected to the bottle mouth 2, a first annular protrusion 5 is arranged on the inner side surface of the bottle mouth 2, a first sealing ring 6 adapted thereto is arranged on the upper end of the first annular protrusion 5, an annular sealing protrusion 9 adapted thereto is arranged inside the bottle cap 3, the annular sealing protrusion 9 can contact the upper end surface of the first sealing ring 6, and in order to facilitate the installation of the above-mentioned first sealing ring 6 on the first annular protrusion 5 and prevent it from falling off, an installation groove 51 is circumferentially opened on the outer side wall of the first annular protrusion 5, an annular mounting ring 7 is arranged on the outer ring of the first sealing ring 6, and the annular mounting ring 7 is clamped in the mounting groove 51, wherein the annular mounting ring 7 and the first sealing ring 6 are integrally formed. The cross-sectional structure of the mounting groove 51 is that the vertical cross-section of the mounting groove 51 is an arc shape, the vertical cross-section of the annular mounting ring 7 is an arc shape adapted to the mounting groove 51, the annular mounting ring 7 is made of rubber, and the arc-shaped mounting groove 51 facilitates the annular mounting ring 7 to be sleeved in the mounting groove 51 to prevent the first sealing ring 6 from falling off.

[0028] like Figure 3 As shown, the structure of the first sealing ring 6 is that the upper end surface of the first sealing ring 6 is an arc surface, and the annular sealing protrusion 9 is provided with an arc groove adapted to the arc surface. The arc surface of the first sealing ring 6 can increase the contact area with the annular sealing protrusion 9, and reduce the phenomenon of essence leakage or air infiltration into the bottle. In order to facilitate the replacement of the first sealing ring 6, the upper end surface of the first annular protrusion 5 is set higher than the upper end surface of the bottle mouth 2, which can reduce the contamination of the essence when the first sealing ring 6 is replaced.

[0029] The first annular protrusion 5 is arranged on the inner side of the bottle mouth 2, and the tube body of the rubber-tipped dropper 4 passes through the first annular protrusion 5 and can extend to the lower part of the bottle body 1. The first annular protrusion 5 is sleeved with a first sealing ring 6, which is convenient for observing the wear and deformation of the first sealing ring 6 and can be replaced in time to reduce the air leakage and liquid leakage caused by the deformation or wear of the first sealing ring 6 and the inability to fit tightly with the first annular protrusion 5. When the bottle cap 3 is tightened on the bottle mouth 2, the first sealing ring 6 is used to be in sealing contact with the annular sealing protrusion 9 in the bottle cap 3 to achieve sealed storage of the essence in the bottle body 1.

[0030] An annular flow shield 8 is also provided on the inner side of the bottle mouth 2, and a through hole 81 is provided in the middle of the annular flow shield 8. The tube body of the rubber-tipped dropper 4 is inserted into the through hole 81. The through hole 81 is arranged in a position where the axis of the through hole 81 is coaxial with the axis of the tube body, and the distance between the hole wall of the through hole 81 and the outer surface of the tube body is 0.1-0.5 cm. The outer surface of the tube body will adhere to the essence, and the distance range can facilitate the taking and placing of the tube body, and can also reduce the essence on the outer wall of the tube body from touching the hole wall of the through hole 81, thereby reducing the waste of the essence.

[0031] In order to facilitate the above-mentioned annular flow shield 8 to block the essence when the bottle body 1 is tilted, the lower surface of the annular flow shield 8 is set as a first inclined surface 82. The first inclined surface 82 is set to be inclined downward from the outer surface of the annular flow shield 8 toward the direction of the through hole 81. The first inclined surface 82 can reduce or prevent the essence from flowing through the bottle mouth 2 to the first sealing ring 6, thereby reducing the leakage of the first sealing ring 6 due to long-term immersion. If the essence in the bottle body 1 is relatively full, the essence may come into contact with the bottle mouth 2 and the first sealing ring 6 through the annular flow shield 8 when the essence storage bottle is poured, and may also adhere to the bottle mouth 2 for a long time. If the bottle cap 3 is directly opened for next use, it will lead to waste of essence. For this reason, the upper surface of the annular flow shield 8 is set as a second inclined surface 83, and the second inclined surface 83 is set to be inclined downward from the outer surface of the annular flow shield 8 in the direction of the through hole 81. In the case that the essence storage bottle is poured for a long time, before the next use, the essence storage bottle can be placed forwardly to allow the essence to flow back into the bottle through the second inclined surface 83, and then the cover can be opened for use, thereby reducing the waste or contamination of the essence at the bottle mouth 2.

[0032] According to the above structure, the beneficial effect that can be achieved by the utility model is that the outer side surface of the annular flow shield 8 is fixedly connected to the inner side surface of the bottle mouth 2 and is tightly arranged. The middle part of the annular flow shield 8 is provided with a through hole 81 for the tube body to penetrate. The prior art only seals the essence through a sealing gasket. If the essence storage bottle is tilted for a long time, the essence in the bottle will adhere to the bottle mouth 2, affecting the next time the bottle cap 3 is unscrewed for use, and the essence in the bottle may seep out through the sealing gasket. The next time the bottle cap 3 is opened to use the essence, contamination may occur. For this reason, an annular flow shield 8 is provided. The annular flow shield 8 can block the essence in the bottle when the essence storage bottle is tilted, reduce or avoid the essence from seeping out of the first sealing ring 6 to the outside of the bottle body 1, and can also reduce the phenomenon of contamination of the essence when it is used.

[0033] like Figure 4 As shown, in order to further improve the sealing effect of the essence and reduce the phenomenon that air infiltrates into the bottle and affects the use of the essence, a second sealing ring 10 is provided on the lower end surface of the bottle cap 3, and the second sealing ring 10 can contact the outer surface of the bottle body 1. The specific structure of the above-mentioned second sealing ring 10 is that the lower surface of the second sealing ring 10 is set as a sealing surface with an arc downward, and the outer surface of the bottle body 1 is provided with a second annular protrusion 11, and the upper surface of the second annular protrusion 11 is matched with the sealing surface. When the bottle cap 3 is tightened, the lower surface of the second sealing ring 10 can contact the upper surface of the second annular protrusion 11, and the arc-shaped sealing surface can increase the contact area with the second annular protrusion 11, thereby improving the sealing effect.
