Description

Technical Field

[0001] The utility model relates to the technical field of lotion pumps, in particular to a lotion pump with a threaded cover. Background Art

[0002] Lotion pumps are widely used in many industries and fields, such as the packaging of lotions, creams, essences and other products in the cosmetics industry, the packaging and delivery of ointments, emulsions, injections and other medicines in the pharmaceutical industry, and the packaging of liquid foods such as sauces, cooking oils, and jams in the food industry. In these applications, the threaded cap lotion pump meets the needs of different industries and consumers for liquid dispensing devices with its high efficiency, hygiene and convenience.

[0003] And in the application document with announcement number CN208915809U, a threaded cap lotion pump is mentioned. The pump body is fixed on the connecting tube on the bottle body by rotating the connecting cap three times, and the cushion block is clamped at the lower end of the connecting tube. Then, the nozzle can be pressed to squeeze the lotion in the bottle through the pump body and spray it out from the nozzle. When the lotion block in the bottle is used up, only a little or it is difficult to spray it out by pressing the nozzle, the cushion block is removed from the crack of the cushion block, and then the cushion block is torn off from one side of the glue layer, and then the connecting cap is rotated downward for one more circle, so that the connecting cap is out of contact with the threaded tube and the smooth tube, and then the connecting cap is moved upward. The bottle cap is then pierced by a sharp block to release the emulsion, which in turn causes the emulsion to be squeezed out of the bottle. The emulsion is then squeezed out as much as possible to avoid wasting the emulsion. However, there are still certain defects that need to be optimized. The specific defects are as follows: the device is cumbersome to use, and the straw is difficult to control when the hose is pierced by a sharp block, which is time-consuming. At the same time, there is no protective device when it is carried out, and it is easy to accidentally release the emulsion.

[0004] Therefore, it is particularly important to design a threaded cap lotion pump to change the above technical defects and improve overall practicality. Utility Model Content

[0024] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0025] A lotion pump with a threaded cap comprises a bottle body 1, wherein a liquid suction tube 2 is arranged inside the bottle body 1, a ball cage 3 is arranged at one end of the liquid suction tube 2, a rubber sleeve 4 is arranged inside the ball cage 3, a gravity ball 5 is arranged inside the rubber sleeve 4, the liquid suction tube 2 is connected to a pump body 6, a first blocking ball 601 is arranged inside the pump body 6, a limiting shell 602 is arranged outside the first blocking ball 601, a compression spring 603 is arranged on the top of the limiting shell 602, an extrusion rod 604 is arranged on the top of the compression spring 603, a first limiting block 605 is arranged outside the pump body 6, the first limiting block 605 is connected to a second limiting block 606, a third limiting block 607 is symmetrically arranged near the top of the extrusion rod 604, a second blocking ball 608 is arranged on the top of the third limiting block 607, and a A pressing rod 609 and a fixing block 7 are provided on the outside of the squeezing rod 604, and slots 701 are provided at both ends of the fixing block 7. A fixing shaft 702 is provided inside the slot 701, and a limiting rod 703 is provided on the outside of the fixing shaft 702. A positioning column 704 is provided on the top of the limiting rod 703. A liquid filling tube 8 is provided on the top of the bottle body 1. Since the internal gravity ball 5 is designed to be stainless steel and has a high density, it can ensure that it always sinks to the vicinity of the bottom of the bottle body, thereby effectively absorbing the lotion. When the pressing rod 609 is pressed, the squeezing rod 604 moves downward accordingly. At this time, the compression spring 603 is compressed. During the downward movement of the squeezing rod 604, the second blocking ball 608 on the top of the third limiting block 607 will leave the outlet inside the pump body 6, allowing the lotion to flow out. At the same time, the first blocking ball 601 is kept at the entrance of the pump body 6 under the action of the compression spring 603 to prevent the emulsion from flowing back. With the release of the pressing rod 609, the compression spring 603 returns to its original state, pushing the squeezing rod 604 and the second blocking ball 608 back to their original positions, and re-closing the outlet of the pump body 6. At this time, due to the action of the gravity ball 5, the suction tube 2 re-absorbs the emulsion and prepares for the next squeezing. In addition, the outer surface of the filling tube 8 is provided with a thread, which can be rotated and fixed in position with the first limiting block 605 through the thread, which is convenient for disassembly and installation. At the same time, when carrying it outside, the limiting rod 703 can be rotated so that the limiting rod 703 is adapted to the limiting groove, and the squeezing rod 604 is limited to avoid the squeezing rod 604 pressing and releasing the emulsion during the activity.

[0026] The outside of the filling tube 8 is provided with a thread, and the first limit block 605 and the filling tube 8 are fixed in position by rotating the thread, which is convenient for installation and disassembly. The second limit block 606 is adapted to the first limit block 605, and the second limit block 606 extends into the interior of the pump body 6 to limit the extrusion rod 604. The first limit block 605 is provided with a limiting groove adapted to the limiting rod 703, and the interior of the fixing block 7 is provided with a card slot adapted to the positioning column 704. The positioning column 704 is made of a rubber column, which is convenient for retracting the limiting rod 703. The pipette 2 is hollow, and a connecting ring is provided at one end of the pipette 2 close to the pump body 6, and a fixing groove is provided inside the connecting ring. A card block adapted to the fixing groove is provided on the pump body 6 for easy installation. The rubber sleeve 4 and the ball cage 3 are fixedly connected. The material of the gravity ball 5 is stainless steel, and the rubber sleeve 4 and the gravity ball 5 are adapted, and a sealing ring is provided at the connection to prevent emulsion from entering the rubber sleeve 4.

[0027] The working process of the utility model is as follows: when using the threaded cap lotion pump, firstly, since the internal gravity ball 5 is designed to be stainless steel and has a high density, it can ensure that it always sinks to the bottom of the bottle body, thereby effectively absorbing the lotion. When the pressing rod 609 is pressed, the squeezing rod 604 moves downward accordingly. At this time, the compression spring 603 is compressed. During the downward movement of the squeezing rod 604, the second blocking ball 608 at the top of the third limiting block 607 will leave the outlet inside the pump body 6, allowing the lotion to flow out. At the same time, the first blocking ball 601 is maintained at the entrance of the pump body 6 under the action of the compression spring 603 to prevent the emulsion from flowing back. As the pressing rod 609 is released, the compression spring 603 returns to its original state, pushing the squeezing rod 604 and the second blocking ball 608 back to their original positions, and re-closing the outlet of the pump body 6. At this time, due to the action of the gravity ball 5, the pipette 2 re-absorbs the emulsion and prepares for the next pressing. In addition, the outside of the filling tube 8 is provided with a thread, which can be rotated and fixed in position with the first limit block 605 through the thread, which is convenient for disassembly and installation. At the same time, when carrying it out, the limit rod 703 can be rotated so that the limit rod 703 is adapted to the limit groove, and the squeezing rod 604 is limited to avoid the squeezing rod 604 pressing and releasing the emulsion during activity.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
