Description

Technical Field

[0001] The utility model relates to the technical field of dropper bottles, in particular to a dropper bottle made of a high-toughness polymer material based on a spiral positioning structure. Background Art

[0002] With the continuous development of science and technology, liquid storage and retrieval containers play an increasingly important role in daily life, especially in laboratories, medical care, chemical industry and other fields, where the requirements for liquid storage containers are more stringent.

[0003] Most of the dropper bottles on the market currently use a simple threaded sealing structure. Although the sealing effect is achieved to a certain extent, the threads are easily worn during frequent opening and closing, resulting in a decrease in sealing performance. The threads are also prone to being too tight during installation, which is sometimes difficult to open quickly and inconvenient to use. In addition, some dropper bottles require the bottle cap to be opened to operate when taking liquid, which not only affects the convenience of operation, but also increases the risk of liquid contamination. Therefore, it is particularly important to develop a dropper bottle that has both good sealing and convenient access to liquid.

[0004] In view of the above problems, the utility model document proposes a dropper bottle made of a high-toughness polymer material based on a spiral positioning structure. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art that most dropper bottles currently use threaded sealing, which is inconvenient to open frequently and the liquid is easily contaminated when taking the dropper, and proposes a dropper bottle of high-toughness polymer material based on a spiral positioning structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The dropper bottle of high-toughness polymer material based on spiral positioning structure includes:

[0008] A bottle body, wherein the bottle body includes a liquid storage cavity provided therein, the liquid storage cavity is used for storing liquid, the bottle body also includes a bottle mouth integrally provided at the top thereof, the outer wall of the bottle mouth is provided with threads, and the bottle mouth is convenient for adding and pouring liquid;

[0009] The fixed cover also includes a cover shell, a top plate and a partition are fixedly installed inside the cover shell, the top plate is located above the partition, a first through hole is opened in the top plate, a second through hole is opened in the partition, the inner wall of the cover shell is provided with a thread, and the cover shell is threadedly connected to the outer wall of the bottle mouth;

[0010] Also included is a sealing assembly, which is used to complete the sealing closure between the first through hole and the second through hole;

[0011] It also includes a rubber-tipped dropper, one end of which passes through the first through hole and the second through hole in the fixed cover and extends to the bottom of the liquid storage cavity. The rubber-tipped dropper is used to absorb the liquid in the liquid storage cavity.

[0012] In a possible design, the sealing assembly includes two fixing rods fixedly installed on the inner wall of the cover body shell, the two fixing rods are located between the top plate and the partition, the outer walls of the two fixing rods are slidably sleeved with fixing blocks, the same sealing plate is fixedly installed between the two fixing blocks, the sealing plate is sealingly and slidingly matched with the side adjacent to the top plate and the partition, the outer walls of the two fixing rods are sleeved with reset springs, one end of the two reset springs is fixedly connected to the inner wall of one side of the cover body shell, and the other side of the two reset springs is fixedly connected to one side of the adjacent fixed block, the sealing plate cooperates with the first through hole and the second through hole, and can complete the shielding and sealing of the first through hole and the second through hole.

[0013] In a possible design, the outer wall of the cover shell is integrally formed with two protruding adjustment parts, and sliders are slidably connected inside the two protruding adjustment parts. Connecting rods are fixedly installed on the sides of the two fixed blocks that are away from each other, and one end of the two connecting rods is fixedly connected to one side of the adjacent slider. The two sliders are used to move the position of the sealing plate to ensure that the rubber-tipped dropper can be smoothly inserted into the liquid storage chamber.

[0014] In a possible design, a limiting ring is fixedly installed on the outer wall of the straw of the rubber-tipped dropper, a limiting groove is provided at the top of the second through hole, the limiting ring cooperates with the limiting groove, an arc groove is provided on one side of the sealing plate and cooperates with the straw part of the fixed cover, and the bottom of the sealing plate cooperates with the limiting ring, so as to realize the pressing limit of the limiting ring.

[0015] In a possible design, the inner diameter of the limiting groove is the same as the inner diameter of the first through hole, and both are larger than the inner diameter of the second through hole, so as to be used for taking out the rubber tip dropper without removing the fixing cover.

[0016] In a possible design, the bottom of the liquid storage chamber is configured to be an inverted cone, so as to concentrate the liquid when there is less liquid in the liquid storage chamber, thereby ensuring that the rubber-tipped dropper can absorb the liquid.

[0017] In the present application, when in use, the user can add liquid into the liquid storage cavity, then screw the fixing cover on the bottle mouth, and then insert the rubber-tipped dropper into the liquid storage cavity through the through hole in the center of the fixing cover. While inserting, move the sliders on both sides to drive the sealing plate to move to one side, so that one end of the rubber-tipped dropper can be smoothly inserted into the liquid storage cavity, and the dropper bottle is ready for use. When the rubber-tipped dropper is fully inserted into the bottle body, the limiting ring can be located in the limiting groove, and the sealing plate will be tightly attached to the straw wall of the rubber-tipped dropper under the action of two return springs, and the bottom of the sealing plate can press the limiting ring to complete the fixing of the limiting ring, so that the rubber-tipped dropper can be fixed in the bottle body, which is not easy to be taken out at will, and the safety of use is relatively high. When the dropper is taken out for use, one way is to directly rotate and remove the fixing cover, and the rubber-tipped dropper can be removed and used together with the fixing cover. Another way is to move the sliders on both sides while keeping the fixing cover stationary. At this time, the sealing plate stops pressing the limit ring, and the user can take out the rubber-tipped dropper. After the rubber-tipped dropper is taken out, the sealing plate will continue to move under the push of the reset spring until the first through hole and the second through hole are completely blocked, and the first through hole and the second through hole are closed, which can ensure that when the rubber-tipped dropper is used, the liquid in the bottle body will not spill out, and the use effect is good. Since the bottom of the liquid storage cavity inside the bottle body adopts an inverted cone design, the liquid in the liquid storage cavity is less, and the remaining liquid can be more concentrated, which is conducive to the rubber-tipped dropper to absorb the liquid.
