Description

{A piston-type spray container that sprays the contents with compressed air}

The present invention relates to a spray container, and more specifically, because it uses a synthetic resin elastic seal instead of a metal spring for compression and return, the used spray container can be discharged as a recycling product, and the contents and compressed air are transferred to the piston. This relates to a piston-type spray container that sprays the contents using compressed air, which prevents the generation of bubbles by separating the container and ensures smooth spraying even when used upside down.

In general, a sprayer is a device that sprays water, mosquito repellent, lubricants, other liquid detergents, and liquid cosmetics in daily life. In addition, the sprayer can be roughly divided into a high-compression type sprayer and a general type sprayer depending on the type of filling inside the sprayer. The high-compression type sprayer is filled with compressed air along with the undiluted solution inside the container, so the undiluted solution is sprayed by opening the pipe. A general sprayer fills only the undiluted solution inside the container and is equipped with a pump or other device that generates suction force to inhale and spray the undiluted solution with suction force.

Figure 1 is a cross-sectional view showing the structure of a conventional high-compression type sprayer filled with compressed air and undiluted solution. As shown in the drawing, it consists of a case (1) and an upper lid (3), and the case (1) is provided with a container (2) filled with compressed air and an undiluted solution, and at the top of the container (2) is a suction pipe ( The injection control unit 4 with 4a) is installed at the bottom, and an operating cap 5 that drives the injection control unit 4 is coupled to the upper part of the injection control unit 4.

In addition, a through hole 8 is formed in front of the operating cap 5 and an injection hole 7 connecting the through hole 8 and the injection control unit 4 is provided, and the injection control unit 4 and the injection hole are provided. A nozzle (6) is provided at the coupling portion (7).

In the sprayer constructed as above, the injection control unit (4) operates as the operating cap (5) is pressed downward, and the stock solution in the container (2) flows through the suction pipe (4a), the nozzle (6), and the injection hole (7). Spraying takes place. At this time, when the sprayer is used in an upright position as shown in the drawing, the stock solution is located on the lower side of the container (2) and the compressed air is located on the upper side. When the operating cap (5) is pressed, the stock solution is sprayed through the spray hole (7) by compressed air. However, when the sprayer is used upside down, the compressed air is located at the top, and when the operating cap (5) is pressed, the compressed air is positioned at the inlet of the suction pipe (4a), so the concentrate is not sprayed and the compressed air is used. There was a problem with spraying.

To solve this problem, a spray container that can be used even upside down has been proposed. However, in such conventional spray containers, when filling the inside of the container with compressed air and undiluted solution, the lower part of the container expands due to strong air pressure. As a result, there was a problem in that the shape was deformed.

Accordingly, in Patent Application No. 10-2020-0079798, the applicant is able to improve the design value of the product by constructing it with two materials, synthetic resin and metal, and forms the bottom of the body in a hemispherical shape to disperse internal pressure. A spray container equipped with an improved pressurized filling dispenser was proposed to prevent deformation of the floor surface.

However, in the above invention, when the container is used with the container facing upside down, the compressed air located at the top of the contents flows into the second space through the hose, lifts the steel ball, and is discharged inside the main body, causing a problem in that smooth pumping and spraying are not achieved. .

In particular, synthetic resin spray containers using conventional metal compression springs have the problem of being unsuitable as eco-friendly products because they cannot be recycled after the contents are used up.

The present invention is intended to solve the above problems, by replacing the metal spring that provides elastic force to the pressing button for spraying the contents by applying an elastic seal made of synthetic resin with elastic restoring force, so that the used spray container can be recycled. The purpose is to provide a piston-type spray container that can be discharged and sprays the contents by compressed air, which is smoothly compressed and returned by an elastic seal.

In addition, the present invention prevents the generation of bubbles by separating the contents and compressed air with a piston, and provides a piston-type spray container that sprays the contents with compressed air that can be used upside down without combining parts to prevent backflow. has another purpose.

One end of the lifting member is coupled to the space so that it can be raised and lowered, and the other end of the lifting member is a pressing button configured to fill the space with contents by rising and falling or to spray the contents of the space to the outside. In this combined piston-type spray container, the lifting member is coupled between the upper cover and the sealing cover, and the guide groove formed on the outer peripheral surface of the lifting member is provided with a plurality of inlets radially to allow the contents of the space to flow in. , the inlet is configured to be opened and closed by an elastic fitting that is in close contact with the inner peripheral surface of the guide groove, and the elastic fitting has a ring-shaped structure of a certain thickness with a hole formed in the center to have elastic restoring force to enable separate collection of recyclables. It is made of synthetic resin material, and when the pressing button is pressed downward, the elevating member is inserted into the space and the inlet is opened, and the contents filled in the space are drawn into the inlet by the rise of the piston by compressed air and sprayed through the nozzle. The contents filled inside the main body move to the inside of the sealing cover by the pressure of compressed air, thereby filling the space again, and the filling contents cause the lifting member to rise and the inlet is sealed with an elastic seal. Do it as
