Description

Quantitative fresh-keeping bottle

technical field

The invention relates to a liquid or powdery solid and liquid separation packaging bottle, in particular to a fresh-keeping bottle for quantitative liquid or powdery solid.

Background technique

For the liquid used for dripping, it is generally packed in a soft plastic bottle. There is a small liquid extrusion port at the front end. The liquid extrusion port has a cover. When using, remove the cover and squeeze the plastic bottle to squeeze out the liquid. This kind of packaging often squeezes the liquid to the periphery of the soft plastic bottle accidentally, so that the liquid in the bottle flows out of the liquid extrusion port. Although the liquid extrusion port has a cap, when you remove the cap next time, the liquid will flow out. A lot of liquid will be spilled from the extrusion port, which will cause the surrounding area of the liquid extrusion port to be unclean, and the oxidative deterioration will affect the use.

In order to solve the above-mentioned problems, a fresh-keeping bottle has appeared on the existing market. The fresh-keeping bottle is made of hard plastic, and there is a piston at the bottom of the bottle that can be manually moved. When the hand pushes the piston to move inward, the volume in the fresh-keeping bottle decreases. , the volume occupied by the air decreases and the air pressure increases, which pushes the liquid to flow out of the liquid extrusion port. However, the movement of the piston belongs to surface-to-surface contact, which can easily cause the liquid in the fresh-keeping bottle to leak. Moreover, consumers need to operate both hands at the same time to complete the dripping, and they cannot free their hands to catch the liquid, which is extremely inconvenient to use. , so it is necessary to improve its structure. The form of product raw materials is not only liquid, but also mainly powdered solid raw materials, but in use, in order to ensure uniform concentration or safety under low concentration use, powdered solid raw materials are often dissolved in a solvent before use, but due to Too much solvent is used, and solution-like solid raw materials bring great changes to storage and transportation, and some powdered solid raw materials are dissolved in solvents, which can easily cause raw material denaturation, such as oxidation, hydrolysis, or polymerization, etc., resulting in the effect of active substances. To reduce failure, powdered solid raw materials and solvents are often packaged separately and mixed before use, which is very beneficial or simple for industrial production.

In the field of medicine, lyophilized powder is the most commonly used method for independent packaging of powdered solid raw materials and liquid solvents. Physiological saline or glucose as a solvent has become a common product. Before use, the nurse will mix the powder with the solvent before use. However, as a powder that needs to be dissolved for civilian use, ordinary people's families will not be equipped with a syringe. Even if other sharp tools can be used, this kind of packaging is inconvenient for people who go out to carry and use. And when the mixture of the two is to be dripped, it is impossible to find a suitable tool.
