Description

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

``Prior Art'' Various types of containers for storing cream-like substances are known. For example, in the device disclosed in Japanese Utility Model Application Publication No. 53-28038, a rod that stands up from the bottom wall is inserted into the container body. The inner plate is attached to the rod so that when the rod is raised by pushing up the bottom wall, the inner plate also rises, and when the rod is lowered, the inner plate stops at the raised position. By moving up and down, the inner tray rises by a certain distance, and by narrowing the storage container, a certain amount of cream-like material is pushed out of the container.

``Problems to be solved by the invention'' If the container is formed so that the inner plate is raised a certain distance by the vertical movement of the rod, as in the case of the conventional container described above, the structure becomes complicated and expensive. It was hot.

The present invention aims at simplifying the structure by forming the container so that the cream-like substance can be sucked out by changing the internal pressure inside the container, thereby making it possible to form the container at a low cost.

"Means for solving the problem" A cylindrical outer part 6 with an open top end is formed in the upper part of the container 1, which has a body part 3 that can reduce the storage volume by creating a negative pressure inside. A nozzle 5 is made to protrude laterally outward from the outer part, and a partition plate 8 with an outflow hole 9 is provided horizontally on the inner surface of the lower end of the outer part, and a suction valve and a discharge valve are installed in the outer part. A plate with a valve 11 having a valve is installed horizontally to open the outflow hole 9.
The suction valve and the discharge valve are communicated with the nozzle hole of the nozzle, and a spherical elastic cap 17 is fitted into the upper end of the outer portion so as to project upward.

"Operation" When the spherical elastic cap 17 is pushed down, the pressure chamber 20, which is the space inside the cylinder between the valved plate 11 and the elastic cap, is pressurized, and the discharge valve of the valved plate 11 opens to release pressurized air. is discharged outwardly through the nozzle 5. Next, when the spherical elastic cap 17 is released, the inside of the pressurized chamber 20 becomes negative pressure due to the elastic return of the cap, and the suction valve of the valved plate 11 opens and the contents stored in the body are sucked up. . By repeating the above operation several times, the items stored in the trunk are poured out from the nozzle 5, and the necessary amount of items stored in the body can be poured out for each subsequent operation.

"Example" 1 shows the entire container. The container has a body 3 with a large-diameter platform 2 at its lower end, and a cylindrical portion 4 with an open top protrudes upward from the upper end of the body.
A nozzle 5 projects outward from a part of the upper side surface of the cylinder. The cylindrical part with the nozzle is connected to the external part 6.
shall be. In this embodiment, the outer portion is formed integrally with the body, but the outer portion may be formed as a separate member from the body as a cap of the container body.

A protrusion 7 is provided around the inner surface of the upper end of the cylindrical portion.

A partition plate 8 is provided on the inner surface of the lower part of the nozzle of the cylindrical portion.
is placed horizontally. An outflow hole 9 is provided in the inner wall portion of the cylindrical portion of the partition plate facing the nozzle.

The inside of the upper cylindrical portion of the partition plate is divided in the vertical direction into a side having a nozzle and a side having an outflow hole by a dividing means 10.

A valved plate 11 is fitted in the cylindrical portion above the dividing means. The valved plate has a circumferential wall 12 that can be airtightly fitted to the inner wall surface of the cylindrical portion, and from the periphery of the through hole bored in one half of the bottom wall at the lower end of the circumferential wall, a first
The small tube 13 is made to protrude upward, and the second small tube 14 is made to protrude downward from the periphery of the through hole bored in the other half of the bottom wall. From a part of the inner surface of the lower end of the first small cylinder, there is an inclined surface that has a bottom surface that almost closes the lower end surface of the first small cylinder, and that gradually rises to the tip and almost closes the inner surface of the first small cylinder. A tongue-shaped first elastic valve body 15 having an upper surface 15a is projected. Further, from a part of the inner surface of the upper end of the second small cylinder, there is formed an inclined surface 1 which has an upper surface that almost closes the upper end surface of the second small cylinder, and which gradually descends toward the tip and almost closes the inner surface of the second small cylinder.
A tongue-shaped second elastic valve body 16 having a lower surface 6a is projected. When the spherical elastic cap described below is pressed down to pressurize the inside of the pressurizing chamber 20, the first and second elastic valve bodies are both pushed downward and try to rotate.
Since the upper surface of the first elastic valve body is an inclined surface that almost closes the inner surface of the first small cylinder in the inclined state, the peripheral edge of the upper surface comes into pressure contact with the inner surface of the first small cylinder as it rotates, thus preventing downward rotation. thwarted. On the other hand, the second elastic valve body 16 is rotated downward and the second small cylindrical hole is opened. Further, when the elastic cap is restored and the pressure inside the pressurizing chamber 20 becomes negative, the second elastic valve body 16 elastically returns to its original position and then tries to rotate inward of the pressurizing chamber 20, but the first For the same reason that the elastic valve body is prevented from rotating downward, the second small cylindrical hole is only hermetically closed, while the first elastic valve body 1
5 is rotated upward to open the first small cylindrical hole. By forming the bottom wall so that the first small cylinder side is low and the second small cylinder side is high, the overall height of the valve plate can be reduced. The first small cylinder has an outflow hole 9
The second small cylinder is positioned above the space having the nozzle, and is fitted with the lower surface of the bottom wall in contact with the upper surface of the dividing means 10. The upper end of the peripheral wall 12 is engaged with the lower edge of the protrusion 7 on the inner surface of the upper end of the cylindrical portion to prevent it from being pulled out. Although this embodiment is configured as in the above embodiment, the upper surface of the space on the side having the outflow hole 9 and the upper surface of the space on the side having the nozzle may be closed separately.

A spherical elastic cap 17 is fitted onto the upper end of the cylindrical portion 4 airtightly and in a convex shape. The elastic cap is provided so that when its center is pushed down, it is depressed against elasticity, and when released, it returns to its original shape due to elasticity.

Reference numeral 18 represents a nozzle cap, and reference numeral 19 represents a bottom plate provided inside the body 3 so as to be slidable upward. The bottom plate rises as the stored items decrease and prevents negative pressure in the body, but this bottom plate is not always necessary. The bag may be placed in a soft bag 21, and the bag may be placed in the body and the bag opening may be airtightly fitted into the outflow hole 9 of the partition plate. Since the bag deforms as the contents decrease, negative pressure does not develop inside the bag.

``Effect of the invention'' The operation is extremely easy because the stored contents can be dispensed by simply pressing down and releasing the spherical elastic cap.
By simply fitting the nozzle into the outer part 6, the outflow hole 9 and the suction valve can communicate with each other, and the nozzle hole of the nozzle 5 and the discharge valve can communicate with each other, thereby simplifying the valve mechanism. The spherical elastic cap also has a simple structure, and since it is only necessary to fit the cap onto the upper end of the outer portion 6, the overall structure can be simplified and the cost can be reduced.
