Technical Field

The invention relates to a spray bottle, in particular to a spray bottle with adjustable dosage.

Background

At present, rhinitis is an inflammation of nasal mucosa, caused by bacteria, viruses, allergens and the like, the incidence rate of rhinitis is as high as 37 percent, and the rhinitis is increased at a speed of 3 percent every year, and juvenile and children rhinitis patients account for 2/3 percent of rhinitis groups.

At present, the traditional nasal cavity medicine applying device special for rhinitis spray medicines is designed with the dose not adjustable. However, the conditions of age, disease development and the like of each rhinitis patient are different, the traditional nasal cavity medicine applying device can not meet the requirement of personalized medicine application obviously, and a fresh rhinitis spray bottle capable of adjusting the dosage is urgently needed in the market.

The rhinitis spray bottle adopts spray package, and the pressure comes from propellant spray or a mechanical pump. Spray package belongs to pressure vessel package. At present, two methods of spraying by using a propellant and spraying by using a mechanical pump exist, wherein in the spraying method by using the mechanical pump, a valve switch is pressed when the mechanical pump is used, so that the contents can be forced to release in the forms of mist, jet flow, powder, foam and the like according to the required forms, such as insecticide, perfume, hair spray, cleanser and the like.

Traditional rhinitis spray bottle includes bottle, shower nozzle and installs the force pump between bottle and shower nozzle, and the import department of force pump is connected with the feed liquor pipe and extends to in the bottle, and the exit linkage of force pump has the drain pipe, is equipped with the nozzle on the shower nozzle, and this nozzle is connected with the drain pipe. When the sprayer is pressed, the sprayer generates pressure on the pressing part (working part) of the pressure pump, the switch inside the pressure pump is opened, so that the liquid inlet pipe and the liquid outlet pipe of the pressure pump are mutually communicated, and then liquid in the bottle body is sprayed out from the nozzle through the liquid inlet pipe, the pressure pump and the liquid outlet pipe. However, the spraying liquid amount of the traditional rhinitis spray bottle is constant, and the dosage cannot be regulated and controlled according to requirements. Wherein, the force pump can be the valve, through the button for the valve is opened, and then the inside high pressure of bottle is with liquid propelling movement in the bottle in the inlet liquid pipe. Such as a spray bottle disclosed on 11/12/2013, or a novel spray squeeze bottle disclosed on 5/2/2021.
