Description

Vacuum dispenser with refill function {Vacuum dispenser with refill function}

The present invention relates to a vacuum dispenser, and in particular, as a technology for refilling contents in a sterile and clean state without exposure to air or contact with tools when refilling, in the medical field, cosmetics field, and various chemical substance handling fields. , It relates to a vacuum dispenser having a refill function applicable to the field of disinfectant handling.

In general, a vacuum pumping container is a container used for daily necessities such as cosmetics or liquid detergents, and is commonly referred to as a dispenser pumping container.

Such a vacuum pumping container is widely used in real life because the contents of the liquid container can be conveniently used in a desired amount, and in order to perform a function, smooth operation is made even for various types or viscosity of contents.

Looking at the structure of such a conventional vacuum dispenser, a cap equipped with a nozzle button is coupled to an upper opening of the container, a piston is inserted into the container, and an air inlet hole is formed under the lower piston of the container. Inside the cap, a suction pipe extends downward from the pump mechanism.

In the operation of a conventional vacuum dispenser, when the nozzle button is pressed, the air inside the container is discharged to the outside along with the contents, and the piston rises by the vacuum formed at this time to lift the contents.

In such a conventional vacuum dispenser, the inside of the container must be kept airtight for smooth discharge, so that the cap is not easily opened from the container, a pressure-down fitting method is taken instead of a screw connection method.

This pressure-down fitting method can achieve the purpose of preventing the container and the cap from being separated, but has some problems. First, since the cap cannot be removed, refilling of the contents, that is, refilling, is difficult, resource recycling for the container is impossible, and separate collection of the container is difficult.

In addition, if there is a defect in the contents for some reason, it was difficult to open it for inspection and repair.

In addition, since the maximum lifting height of the piston is regulated by the lower end of the suction pipe, the remaining amount of the remaining amount in the container cannot be discharged at the maximum elevation position of the piston, and thus it is impossible to use, resulting in waste of resources.

In addition, adopting a simple screw-type coupling method instead of the pressure-down fitting method has the advantage of being able to easily open the cap so that the contents can be easily refilled, but there is a problem in that contamination due to contact with air occurs.

In addition, conventional vacuum dispensers mainly use the pouring method when refilling viscous contents, but due to the viscosity, they are adhered to the inlet or inner wall of the container, so that the injection is not smooth, so the operator must strike the container to move the contents. There was an uncomfortable problem.

In addition, in the case of refilling a viscous content in a conventional vacuum dispenser, voids are generated between the content and the content, unlike liquid, so that voids are generated due to air inflow, oxidation of the content, changes in physical properties, and pumping is not smooth. There was this.

In particular, the applicant of the present invention is a worker who performs physical therapy to restore and activate the tissue of the affected area through pain relief and thermal therapy by irradiating high frequency to the affected area of the patient using a high frequency device. With the electrodes inserted between the fingers of both hands, the exclusive cream contained in the dispenser was pumped and used in order to reduce friction with the affected area and increase the conduction of spherical waves and heat.

However, when all the exclusive cream is used, the purchase price increases as the dispenser containing the exclusive cream must be purchased. If the exclusive cream is purchased separately and refilled, it is not easy to inject, and the exclusive cream is exposed to the air and contaminated. Was found.

Due to this, refilling of the contents is smooth and no air contact occurs during refilling, so no pollution or change in physical properties occurs, and the filling rate is excellent due to the non-occurrence of voids between contents, and an improved refill only to maintain a constant pumping power. There is an urgent need for a vacuum dispenser.
