Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bottles, in particular to a pump head for packaging bottles. Background Art
[0002] Packaging bottles are widely used in technical fields such as cosmetic packaging and pharmaceutical packaging to hold pastes or emulsions with high viscosity.
[0003] When the packaging bottle is filled with low-fluidity inner materials, the material remaining at the pump head outlet will gradually lose water, dry and agglomerate due to long-term contact with air during use. In severe cases, it will oxidize and deteriorate, clog the pump head, affect the normal use of the product, and affect the consumer's experience. For this reason, a pump head that prevents pump head clogging has appeared on the market.
[0004] For example, a patent document with publication number CN216660976U discloses a pump head for packaging bottles, including an outer cover, a pressure head is fixedly connected to the inner side of the outer cover, a nozzle is connected to the inner side of the right end of the pressure head, and a sealing mechanism for protecting the nozzle is arranged on the inner side of the nozzle. Compared with the prior art, the pressure block, connecting shaft, rubber cloth, pressure block, first spring, limit plate, limit block, first wedge block, second wedge block and second spring are provided. When in use, the pressure block is pressed, and the pressure block is separated from the nozzle under the action of the pressure block, and then the emulsion can flow out through the nozzle. When not in use, the block is re-engaged with the nozzle under the action of the second spring, and the nozzle is sealed by the block to ensure that the emulsion remaining in the nozzle will not flow out of the nozzle. At the same time, foreign matter can be prevented from entering the inside of the nozzle, and the emulsion inside the nozzle can be prevented from drying.
[0005] However, in the above technology, through the cooperation between the blocking block, connecting shaft, rubber cloth, pressure block, first spring, limit plate, limit block, first wedge block, second wedge block and second spring, the pressure block is pressed during use, and the blocking block is separated from the nozzle under the action of the pressure block, and then the emulsion can flow out through the nozzle. When not in use, the blocking block is re-engaged with the nozzle under the action of the second spring, and the nozzle is sealed by the blocking block. The structure of the prior art is relatively complicated, the assembly is difficult, and the manufacturing cost is also increased.
[0006] Therefore, a pump head for a packaging bottle is proposed to solve the above technical problems. Utility Model Content
