Description

[Detailed explanation of the idea] "Industrial application field" This case relates to containers for storing creamy substances.

``Prior art'' For example, as shown in Japanese Patent Application Laid-Open No. 56-95870, there is a main body of a container with a neck and a neck erected as a cylinder from the upper end of a body with the same inner diameter and an opening at the lower end via a shoulder, and the neck of the container. an actuating member with a discharge valve that protrudes a nozzle from the upper end of the discharge pipe that is fitted and urged upward in a watertight manner so as to be movable up and down; and a sliding plate which is fit into the inner surface of the body in a water-tight manner so as to be able to rise, and the cream-like material in the container main body is discharged from the nozzle by vertical movement of the operating member relative to the container main body, and the cream-like material is discharged from the container main body through the nozzle. A cream-like substance storage container is known in which a sliding plate is raised to eliminate negative pressure inside the main body of the container due to the decrease in pressure.

``The problem that the invention attempts to solve'' The conventional cream storage container as mentioned above is
Since the discharge valve is provided at the connecting part between the upper end of the discharge pipe and the base end of the nozzle hole in the cream discharge path that extends from the main body of the container to the tip of the nozzle hole, there is a gap between the discharge valve and the tip of the nozzle hole. The cream-like material remaining in the nozzle hole may dry and become clogged, and since it has only a discharge valve and no suction valve, the cream-like material discharge function is deteriorated.

The present invention eliminates such drawbacks and particularly simplifies the structure of the discharge valve.

"Means for Solving the Problem" The body part 2 having the same inner diameter above and below is hung from the periphery of the top wall 3, and a valve hole 8 with a suction valve 7 is bored in the center of the top wall, and the valve hole cylinder 4 surrounding
a container main body 1 that stands up, a discharge pipe 12 that stands up from a cylindrical piston 11 that is fitted into the cylinder in an upward biased state, and an operating member 10 that projects a rod-shaped nozzle 13 from the upper end of the discharge pipe; A sliding plate 17 is fitted into the lower part of the main body body 2 of the container so that the outer peripheral surface thereof is in watertight contact with the inner surface of the body so as to be able to rise to the top;
By fitting the rubber cap 16 to the tip of the rod-shaped nozzle 13, a top wall 16a of the rubber cap is formed.
Then fit the nozzle hole 13a opened in the nozzle tip surface into the discharge hole 16b bored in the top wall of the rubber cap with the small protrusion 18a protruding from the nozzle tip surface, and use the small protrusion to open the discharge hole 16b. , and the pressure inside the nozzle hole 13a is increased by pressing down the actuating member against the main body of the container, so that the top wall 16a of the rubber cap is elastically deformed, and the nozzle hole 13a and the discharge hole 16b are formed to be able to communicate with each other.

"Action" From the illustrated state, the actuating member 10 is applied to the container main body 1.
When pressed down, the suction valve 7 and nozzle hole 13
Since the tip surface a is closed, the pressure inside the cylinder 4, discharge pipe 12, nozzle hole 13a, etc. becomes high, and the top wall 16a of the rubber cap 16 that seals the tip surface of the nozzle hole is elastically deformed and the discharge hole is closed. 16b is removed from the small protrusion 18a, and the nozzle hole and the discharge hole 16b formed in the top wall of the rubber cap communicate with each other, and the air inside the nozzle hole etc. is discharged.
Immediately after discharge, the discharge hole and nozzle hole are closed by the elastic restoration of the top wall of the rubber cap, so when the actuating member is released, the actuating member rises and the discharge pipe 12
The inside becomes negative pressure, and then the suction valve 7 opens to suck the creamy substance inside the main body of the container into the cylinder and the discharge pipe, and the creamy substance is discharged from the discharge hole 16b by pressing down the actuating member again. As the creamy substance inside the container main body decreases, the sliding plate 17 rises to eliminate the negative pressure inside the container main body.

``Embodiment'' 1 is mainly a container, with a body 2 having the same inner diameter on the upper and lower sides hanging from the outer periphery of the top wall 3. A valve hole 8 with a suction valve 7 is bored in the center of the top wall, and the cylinder 4 is erected surrounding the valve hole. The suction valve 7 is of a known type, and has a circumferential wall 7a that is fitted into the lower part of the cylinder from the outer periphery of the bottom plate, and a tongue-shaped elastic plate as a valve plate 7b is attached to the bottom plate in a C-shape as shown in FIG. It is formed by drilling a separation line 7c, and the valve plate 7b closes the upper surface of the valve hole 8. A guide cylinder 6 having a first engaging protrusion 5 provided around the inner surface of the upper end may be erected from the outer periphery of the top wall.

The cylindrical piston 11 of the actuating member 10 is fitted into the cylinder 4 by being biased upward by the spring 9. Further, the lower part of the discharge pipe 12 whose upper end is closed is fitted into the cylindrical piston, and the rod-shaped nozzle 13 is protruded from the upper end side of the discharge pipe to form an operating member. As shown in the figure, the nozzle hole 13a of the nozzle preferably has an annular concave groove on its distal end side, and a passage hole communicating the inner surface of the discharge pipe hole and the base end of the annular concave groove on its proximal end side. A small protrusion 18a projects from the center of the tip surface of the rod-shaped portion 18 surrounded by the annular groove. A cover 14 may be fitted to the discharge pipe 12, and in the illustrated example, a cover circumferential wall is provided vertically and fitted into the guide cylinder 6 so as to be movable up and down, and a cover 14 is provided around the outer surface of the lower end of the cover circumferential wall. By engaging the second engagement protrusion 15 with the lower surface of the first engagement protrusion 5 described above, the operating member 10 is prevented from slipping out of the container main body 1.

The sliding plate 17 is fit into the lower part of the main body body 2 of the container so as to be able to rise, with its outer circumferential surface being in watertight contact with the inner surface of the body. The sliding plate may be formed in a known manner.

A rubber cap 16 is attached to the tip of the nozzle 13 described above.
mate. The rubber cap has its top wall 16a
It has a discharge hole 16b in the center, and the aforementioned small protrusion 18a is fitted into the discharge hole to seal the discharge hole 16b. Further, the inner surface of the top wall 16a seals the opening surface of the nozzle hole 13a which opens at the tip surface of the nozzle described above. As shown in the figure, the rubber cap 16 is preferably pressed by a short tightening tube 19 fitted to the outer periphery of the nozzle tip to press the outer periphery of the rubber cap's peripheral wall and top wall to prevent the rubber cap from detaching from the nozzle tip.

The nozzle 13 is constructed by forming a nozzle hole on the axis of the nozzle, and closing the opening surface of the nozzle hole opening at the tip of the nozzle with the inner surface of the center of the top wall of the cap, as is usually done. A discharge hole 16b may be formed in the top wall portion of the nozzle, and the discharge hole may be closed by fitting a small protrusion projecting from the nozzle tip surface.
The opening surface at the tip of the nozzle hole, the top wall portion of the rubber cap, the discharge hole 16b, and the small protrusion form a discharge valve.

``Effect of the invention'' The present invention has the above-mentioned configuration, and in addition to the suction valve 7, a rubber cap 16 is fitted to the nozzle tip, and holes are formed in the nozzle hole opening surface of the nozzle tip surface, the top wall of the rubber cap, and the top wall. Since a discharge valve is formed by the discharge hole and the small protrusion fitted into the discharge pipe, pressurization and depressurization inside the cylinder 4, etc. are ensured, and the cream-like material can be sucked up and discharged reliably. In addition, the discharge valve is formed such that the nozzle hole opening surface is the top wall of the rubber cap 16a, and the discharge hole 16b bored in the top wall of the rubber cap is the nozzle 1.
3. It is extremely easy to do this by simply shifting the positions of both holes and fitting the rubber cap 16 to the nozzle tip so that the small protrusions 18a protruding from the tip surface seal each other. Since the discharge hole 16b bored in the top wall of the rubber cap is double-sealed with a small protrusion 18a protruding from the nozzle tip surface, the elasticity of the rubber cap ensures that the nozzle hole and the discharge hole are not blocked. This method eliminates the possibility of blocking the valve due to the adhesion of creamy substances, as is the case with ordinary check valves, such as ball valves. The creamy material is exposed to outside air and dries, so the nozzle hole is never clogged.Also, if the rubber cap ages and loses its elasticity, the rubber cap can be placed at the tip of the nozzle. Since it is simply fitted, it can be easily replaced.
