BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creamy material discharging container.

[0002]

[Prior art]

SUMMARY OF THE INVENTION A sliding bottom plate hermetically fitted into the lower part of the body of the container by sucking and discharging the cream inside the container by the operation of the pump device mounted on the upper end of the container. There is widely known a cream-like material discharge container provided to prevent the pressure from rising and negative pressure in the container body, and the device disclosed in Japanese Utility Model Laid-Open Publication No. 4-29988 discloses such a container. From the center of the bottom wall of the bottom lid that closes the lower end, the upper end is raised from the center to the supporting cylinder that abuts the lower surface of the sliding bottom plate. Even if the pressure is slightly increased, the sliding bottom plate is provided so as to prevent the sliding bottom plate from falling out of the body.

[0003] However, in the case of the above-mentioned conventional container, the weight of the stored cream concentrates at the center of the bottom wall of the bottom lid, so that the bottom wall is easily elastically deformed and the bottom wall is slightly elastically deformed. However, the container body was not well seated, so it was very bad.

In the present invention, a reinforcing plate is attached to the bottom wall,
The bottom wall was provided such that elastic deformation hardly occurred.

[0005]

The sliding bottom plate fitted into the bottom of the body of the container rises by sucking and discharging the cream inside the container by the operation of the pump device mounted on the upper end of the container. In the cream-like material discharge container provided so as to prevent negative pressure inside the container body, the lower end surface of the body is closed with a fixed bottom cover 8, and from the center of the bottom plate 9 of the fixed bottom cover,
Support cylinder 11 whose upper end is in contact with the center of the lower surface of sliding bottom plate 6
And a plurality of reinforcing plates 12 projecting radially from the outer surface of the lower end of the support cylinder and connected to the bottom plate 9.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a container body, which has a pump device 3 mounted on the upper end of a body 2 and which is pressed by a pressing head 4 at the upper end of an operating member. The cream-like substance in the cylinder which is suspended in the body is discharged from the nozzle 5, and the body-like cream-like substance is sucked into the cylinder 2 by raising the operating member by releasing the press-down head 4.

A sliding bottom plate 6 is fitted airtightly to the lower inner surface of the body 2 and the sliding bottom plate 6 rises as the cream inside the container decreases due to the discharge of the cream. It is formed to prevent negative pressure inside the body.

The lower end surface of the body 2 of the container is closed by a fixed bottom lid 8.

The fixed bottom cover has inner and outer double mounting cylinder portions 10a and 10b rising from the peripheral edge of the bottom plate 9. The lower end of the body portion 2 is fitted between these mounting cylinder portions. From the central part, a support cylinder part 11 whose upper end part is in contact with the central part of the lower surface of the sliding bottom plate 6 described above is erected, and is radiated from the lower end outer surface of the support cylinder part and connected to the bottom plate 9 to form a plurality of support cylinder parts. The reinforcing plates 12 are provided so as to protrude.

In addition, the sliding bottom plate 6 rises up to the bottom plate 9 portion surrounded by the supporting tubular portion 11, so that the pressure in the body portion between the sliding bottom plate and the fixed bottom lid 8 is reduced. An outside air suction hole 13 for preventing the occurrence of air is provided.

The hole may be formed in another bottom plate portion.

[0012]

[Effects of the Invention] The present invention has the above-described structure. Since a plurality of reinforcing plates 12 are projected from the outer surface of the lower end of the support cylinder 11 radially and connected to the bottom plate 9, the bottom plate 9 is elastically deformed. Thus, the disadvantage that the bottom plate 9 is elastically deformed and the container is not seated properly is solved.

Claims (1)

(57) [Scope of request for utility model registration] The sliding bottom plate fitted into the bottom of the container body rises by suction and discharge of the cream inside the container by the operation of the pump device mounted on the upper end portion of the container body, and rises. In the cream-like material discharge container provided to prevent the negative pressure from being generated, the lower end surface of the body is closed with a fixed bottom cover 8, and the upper end portion is moved from the center of the bottom plate 9 of the fixed bottom cover to the sliding bottom plate. 6, a plurality of reinforcing plates 12 projecting from the outer surface of the lower end of the supporting tube portion radially and connected to the bottom plate 9 to stand upright at the center of the lower surface of the supporting tube portion. Cream-like discharge container.
