Description

Spray bottle capable of adjusting dosage

Technical Field

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

Background

At present, rhinitis is taken as a nasal mucosa inflammation, and is caused by bacteria, viruses, allergens and the like, the incidence rate of the rhinitis which is past by me is up to 37%, and the rhinitis of teenagers and children accounts for as much as 2/3 of the rhinitis population at a rate of 3% each year.

At present, a traditional nasal cavity medicine feeder special for rhinitis spray medicines is designed for not adjusting the dosage. However, the age, disease development and other conditions of each rhinitis patient are different, the traditional nasal cavity medicine feeder obviously cannot meet the requirement of personalized medicine administration, and a fresh rhinitis spray bottle capable of adjusting the medicine dosage is urgently needed in the market.

Rhinitis spray bottles are packaged with sprays, the pressure being from either the propellant spray or a mechanical pump. Spray packaging belongs to the field of pressure vessel packaging. There are two modes of spraying by using a propellant and spraying by using a mechanical pump, wherein in the mode of spraying by using the mechanical pump, a valve switch is pressed during use, so that the content can be forced to be released according to the required form, such as mist, jet, powder, foam and the like, such as insecticide, perfume, hair spray, cleaning agent and the like.

The traditional rhinitis spray bottle comprises a bottle body, a spray head and a pressure pump arranged between the bottle body and the spray head, wherein an inlet of the pressure pump is connected with a liquid inlet pipe and extends into the bottle body, an outlet of the pressure pump is connected with a liquid outlet pipe, and a nozzle is arranged on the spray head and connected with the liquid outlet pipe. When the spray head is pressed, the spray head generates pressure to a pressing part (working part) of the pressure pump, and an internal switch of the pressure pump is opened, so that a liquid inlet pipe and a liquid outlet pipe of the pressure pump are communicated with each other, and then liquid in the bottle body is sprayed out from a nozzle through the liquid inlet pipe, the pressure pump and the liquid outlet pipe. However, the spraying amount of the traditional rhinitis spray bottle is constant, and the dosage cannot be regulated according to the requirement. The pressure pump can be a valve, and the valve is opened through a key, so that the inside of the bottle body is high in pressure, and liquid in the bottle body is pushed into the liquid inlet pipe. The patent name disclosed in 2013, 12, 11 is a "spray bottle", or 2020203467295, and in 2021, 2, 5 is a "novel spray squeeze bottle", as applied for 2013203680741.
