Technical Field

[0001] This utility model belongs to the technical field of plastic spray bottles, specifically relating to a three-section press-type spray bottle. Background Technology

[0002] Plastic spray bottles are made of medical-grade plastic (PP / PE / PET) with an integrated mechanical atomizing pump encapsulation system. Pressing the pump triggers the pump to convert the liquid into an aerosol. These plastic spray bottles are precision drug delivery devices designed for liquid medications, using atomization / spray technology to deliver drugs to the nasal cavity, oral cavity, and skin. Pharmaceutical spray bottles can be used for administering nasal sprays, oral sprays, and skin sprays.

[0003] Press-type spray bottles deliver spray by pressing, allowing users to dispense different doses of spray by pressing to varying depths. However, conventional press-type spray bottles lack adjustable settings, making it difficult for users to control the depth of their press and thus making it challenging to control the dosage per press.
