Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cream-like material dispensing container for storing, for example, paste-like seasonings.

"Prior art" As shown in Utility Model Application No. 57-44041, a pressurized chamber having a suction valve and a discharge valve is provided in the upper part of the container body,
When the hemispherical elastic wall that forms part of the wall of the pressurized chamber is squeezed, the suction valve closes, the discharge valve opens, and the cream-like material in the pressurized chamber is extruded from the nozzle, and the hemispherical elastic wall is released. When the discharge valve closes and the suction valve opens, the pressure inside the pressurized chamber becomes negative due to the elastic restoration of the elastic wall, and the creamy substance inside the container is sucked up into the pressurized chamber through the suction valve. A cream dispensing container is known in which a sliding bottom plate fitted into the bottom of the container body rises when the pressure becomes negative, thereby preventing the pressure from becoming negative.

``Problems to be Solved by the Invention'' Conventional containers of this kind have the disadvantage that they tend to be difficult to mold due to their complicated structures, and the number of parts increases, leading to high costs.

The present invention has a structure that allows the number of members to be reduced, thereby reducing costs, and also enables the cream-like substance to be easily dispensed by operating a lever.

"Means for Solving the Problem" The upper surface of the first peripheral wall 2, which is open at the bottom, is closed with the first top wall 3, and the fitting wall 4 is extended from the outer periphery of the first top wall, and the front part of the fitting wall is closed. A container body 1 in which a fitting tube 5 stands up from the upper surface of a first top wall with a gap between the container body 1 and the inner surface, and a suction hole 7 is formed in the first top wall portion surrounded by the fitting tube; A sliding bottom plate 8 is fit into the lower part of the first circumferential wall so as to be able to rise with its outer circumferential portion in watertight contact with the inner surface of the first circumferential wall, and a second circumferential wall is airtightly fitted into the fitting wall 4. 15 is suspended from the second top wall 16, and the lower end of an elastic cap-shaped part 17, which is a hemispherically raised part of the second top wall, is fitted into the fitting cylinder 5, and the second top wall above the gap is fitted. A suction member 14 in which a nozzle 18 with a discharge valve 21 is erected by opening a hole in a portion thereof, and a third peripheral wall 24 that is vertically disposed on the outer surface of the first or second peripheral wall 2, 15 from the peripheral edge of the third top wall. The lower part is fitted, and the upper surface of the elastic cap-shaped part compression lever 27 and the nozzle are opened and closed by being surrounded by the separation line 25 and the bending line 26 provided on the third top wall and the upper part of the third peripheral wall. A cap-shaped member 22 provided with a lid plate 28 for
The suction hole 7 and the lower end of the nozzle were communicated through an outflow path.

"Operation" When the lid plate 28 is opened from the state shown in FIG. 1 and the lever 27 is pushed down against the container body 1, the elastic cap-shaped part 1
When 7 is pressed down, the pressure is applied to the discharge valve 2.
1 is opened, and the creamy substance in the elastic cap-shaped portion is discharged from the nozzle 18 through the discharge valve 21. Next, when the lever 27 is released, the discharge valve 21 is closed by the elastic restoration of the elastic cap-shaped part, and the cream-like substance in the container body is sucked up into the elastic cap-shaped part, and at the same time, the sliding bottom plate 8 is also sucked up. It rises due to negative pressure inside the container body due to suction. After use, close the lid plate 28 again.

"Example" 1 is a container main body, in which the upper surface of a first circumferential wall 2 whose lower surface is open is closed with a first top wall 3, and a fitting wall 4 is extended from the outer periphery of the first top wall, and a fitting wall 4 is connected arbitrarily to the fitting wall. The fitting cylinders 5 are respectively made to stand up from the upper surface of the first top wall with a gap between them and the defined front inner surface. The respective rear portions of the fitting wall 4 and the fitting tube 5 may be integrated as shown in the figure by making the fitting tube higher. A notch 6 for forming an outflow path is provided in a front portion of the fitting tube 5, and a suction hole 7 is bored in the first top wall portion surrounded by the fitting tube. The upper end portion of the first circumferential wall 2 and the fitting wall 4 of the container body are formed at a small outer diameter portion, and the first circumferential wall portion immediately below the small outer diameter portion is formed at an intermediate outer diameter portion.

A sliding bottom plate 8 is fitted into the lower part of the first peripheral wall so as to be able to rise. The sliding bottom plate has a cylindrical passage 10 hanging down from the outer periphery of the top plate 9, and a skirt-like portion 11 that is in watertight contact with the inner surface of the first peripheral wall 2 is attached to the outer surface of the cylindrical portion. Furthermore, a concave groove is provided around the outer surface of the lower part of the cylindrical part, and the upper end ring part of the metal return prevention member 12 is fitted into the concave groove, and a plurality of claws are expanded downward and outward from the ring part. 13 is engaged with the inner surface of the first peripheral wall. The return prevention member is designed to prevent the member from being pushed down through the cream-like substance filled in the container body when the elastic cap-shaped portion described below is squeezed, and a suction valve is provided in the suction hole 7 described above. It can be omitted.

A suction member 14 is fitted to the upper end of the container body. In this member, the second peripheral wall 15, which is airtightly fitted to the above-mentioned fitting wall 4, hangs down from the outer periphery of the second top wall 16, and a part of the second top wall is raised in a hemispherical shape to form an elastic cap-shaped portion. 17, and the lower end of the elastic cap is fitted into the fitting tube 5. Further, a hole is opened in a portion of the second top wall above the gap between the fitting wall 4 and the fitting cylinder 5 in the front part of the first top wall 3, and the nozzle 18 is made to stand from the periphery of the hole. Further, a tongue-shaped valve plate 19 protrudes from the lower end of the nozzle, a portion of which is connected to the lower end of the nozzle to elastically close the lower end of the nozzle hole 18a.A tongue-shaped valve plate 19 is provided on the lower surface of the valve plate to prevent the valve plate from moving downward. A protrusion 20 is attached so that the lower end of the protrusion is in contact with the upper surface of the first top wall. The valve plate thus pivots only upwards to form the discharge valve 21. The suction hole 7 and the lower end of the nozzle communicate with each other through an outflow path.

Reference numeral 22 denotes a cap-like member, and the lower end of the third peripheral wall 24 hanging down from the peripheral edge of the third top wall 23 is fitted into the middle and outer diameter portion of the first peripheral wall of the container main body. However, it may be fitted onto the second peripheral wall. The third top wall 23 and the upper part of the third peripheral wall are surrounded by a separation line 25 and a bending line 26 to form a lever 27 for compressing the elastic cap-shaped portion and a cover plate 28 for opening and closing the upper surface of the nozzle. A push-down cylinder 29 hangs down from the lower surface of the lever 27 and is brought into contact with the upper surface of the elastic cap-shaped portion 17. Further, a short tube is suspended from the lower surface of the cover plate 28 to be fitted into the inner surface of the upper end of the nozzle.

``Effect of the invention'' Since the present invention has the above-mentioned structure, it can be formed from five members: the container body 1, the sliding bottom plate 8, the suction member 14, and the cap-shaped member 22, and the structure of each member is synthetic. It is convenient because it is provided so that it can be easily integrally molded with resin material, and furthermore, the cap-shaped member 22
Since it has a lever 27 for squeezing the elastic cap-shaped part and a lid plate 28 for opening and closing the top surface of the nozzle, it has the advantage that the operation of dispensing the cream is easy and there is no need to separately provide a mouth cap for opening and closing the nozzle.
