Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a coating container that stores a cream-like content and extrudes the content to apply it directly onto the surface of an object.

[Conventional technology]

A container used to store cream-like contents such as shoe cream and to extrude the contents and apply it directly to the surface of the object is a straight cylindrical container with a bottom plate attached to the lower end of the container so that it can rotate freely. Many valves are used in which a valve body for pushing out the contents is attached to a threaded rod erected in the center of the top surface of the bottom plate.

This type has the advantage of being easy to use and being able to accurately control the amount of content to be extruded. It is necessary to assemble the valve body relatively densely, so as the consumption of the contents increases and the valve body moves upward,
Negative pressure is generated in the space inside the container body between the valve body and the bottom plate, and this negative pressure may make it impossible to obtain a smooth upward movement of the valve body, or cause the cream-like contents stored therein to There has been an inconvenience in that a portion of the valve leaks downward from the mechanism where the valve body and the threaded rod are screwed together.

For example, there is an extruded container disclosed in Japanese Utility Model Application Publication No. 56-034775 to prevent the above-mentioned disadvantage from occurring.

In the push-out container disclosed in Japanese Utility Model Application Publication No. 56-034775, the means for preventing the generation of negative pressure in the space below the valve body in the container body due to the upward displacement of the valve body is a means for preventing the generation of negative pressure in the space below the valve body in the container body. A ventilation hole is formed in a part of the tray, and the tray is attached to the bottom wall, that is, the container body, so that it can be moved up and down although it cannot rotate. The structure includes a closing member that closes the ventilation hole.

[The problem that the idea aims to solve]

The means for preventing the generation of negative pressure in a push-out container disclosed in the above-mentioned Japanese Utility Model Publication No. 56-034775 certainly prevents the generation of negative pressure in the space below the valve body in the container body due to upward displacement of the saucer, that is, the valve body. However, since the bottom wall with the vent hole is molded integrally with the container body, it is necessary to assemble the valve body to the container body so that it cannot rotate. Therefore, the structure of the extrusion container main body is significantly limited, and there is a problem that the structure for upwardly displacing the valve body becomes complicated.

In addition, since the ventilation hole is provided apart from the screw rod, it is not possible to prevent the contents from leaking from the mechanism where the screw rod and the valve body are screwed together. There was a problem in that no consideration was given to preventing the contents from leaking from the parts.

The present invention was devised to solve the problems in the prior art described above, and includes a means for preventing the generation of negative pressure in the space below the valve body in the container body on the bottom plate body having a threaded rod. To obtain a smooth upward displacement movement of the body, and to prevent contents from leaking from a mechanism part with a threaded assembly of a threaded rod and a valve body by means of preventing the generation of negative pressure. The purpose is to make it possible.

[Means to solve the problem]

The means of the present invention for achieving the above object consists of a straight cylindrical container body with an applicator attached to the upper end, and a bottom plate attached to the lower end opening of the container body, which is rotatable but cannot be pulled out. and a valve body which is screwed onto a screw rod installed upright in the center of the bottom plate body, and whose peripheral edge is brought into close contact with the inner peripheral surface of the container body, and the base end of the screw rod. A cylindrical base having a cylindrical shape that is open to the outside by opening at the bottom surface of the bottom plate body, a vent hole being opened in the cylindrical wall of this cylindrical base, and a valve body having a position in which the valve body is in the lowering limit position. Providing a seal cylinder piece that closes the ventilation hole when in position.

Note that since the bottom plate body is rotatably assembled to the container body, the valve body is assembled so that it can be moved up and down relative to the container body, but cannot be rotated.

[Effect]

When the bottom plate is rotated in a predetermined direction relative to the container body, the valve body is upwardly displaced within the container body due to the rotation of the bottom plate relative to the container body.

Due to this upward displacement of the valve body with respect to the container body,
The cream-like contents stored in the container body above the valve body are pressurized and pushed out from the spout formed at the upper end of the container body onto the surface of the application body, and the extruded contents are transferred to the application body. It can be applied directly to the surface of the target object.

When the valve body is displaced upward within the container body as the contents are pushed out, the seal cylinder piece integrally formed with the valve body is also displaced upward with respect to the threaded rod, that is, the vent hole, and this seal cylinder piece Due to the upward displacement of the valve body with respect to the vent hole, the closure of the vent hole by the seal cylinder piece is released, and the inside of the container body below the valve body is opened to the outside through the vent hole. This will prevent the generation of negative pressure within the main body.

In addition, the combination mechanism of the ventilation hole and the seal cylinder piece is
Since it is located directly below the threaded assembly mechanism of the threaded rod and the valve body, the seal cylinder piece is brought into close contact with the outer circumferential surface of the cylindrical base to achieve sealing of the assembled portion of the threaded rod and the valve body. Therefore, when assembling the container, in which the combination of the bottom plate body and the valve body is assembled to the container body filled with the contents and the container body is sealed, the above-mentioned screw rod and valve body of the contents can be assembled. It is possible to prevent leakage from the threaded assembly mechanism.

In other words, the cream-like contents are stored in a container by injecting and filling a certain amount of the heated and highly fluid contents from the bottom opening of the container body which is in an upright position, and then This is achieved by assembling the combination of the bottom plate and the valve body into the lower end opening of the container body, and cooling the contents to form a cream. In this way, the combination of the bottom plate and the valve body is assembled to the container body while the contents are in a highly fluid state, so that the liquid contents are transferred to the screw rod and the valve body. It leaks through the mechanism part that is screwed together with the body, but since the seal cylinder piece is in close contact with the outer peripheral surface of the cylindrical base and seals between the bottom plate body and the valve body, this liquid leaks out. This reliably prevents the contents from leaking out.

[Effect of idea]

Since the present invention has the above-described configuration, it exhibits the following effects.

By providing a ventilation hole in the cylindrical base that is the base of the screw rod, the inside of the container body below the valve body is communicated with the outside, so as the valve body moves upward within the container body, the air below the valve body is communicated with the outside. No negative pressure is generated within the container body, which allows the valve body to move upward smoothly relative to the container body, making it possible to achieve extremely good extrusion of the contents from the container body. .

The vent hole is formed in the cylindrical wall of the cylindrical base, and the seal cylinder piece that closes this vent hole is formed in the threaded barrel of the valve body that is threaded into the threaded rod that forms the cylindrical base. Regardless of the combination of the interaction between the bottom plate, the screw rod, and the valve body, it is possible to reliably achieve sealing with the sealing cylinder piece of the vent hole, so that the entire structure of the coating container is compatible with this vent hole. The structure of the coating container can be freely set without being restricted by the relationship with the seal cylinder piece.

The seal cylinder piece that seals the ventilation hole in close contact with the outer circumferential surface of the tube base is located directly below the mechanism part where the threaded rod and the valve body are screwed together, so that the threaded connection between the screw rod and the valve body is prevented. This seal cylinder piece firmly and reliably prevents unauthorized leakage of contents through the assembled mechanism portion, thereby eliminating the occurrence of stains due to unauthorized leakage of contents.
