BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for dispensing cream.

[0002]

[Prior art]

As a container for storing a highly viscous cream such as cosmetics and pharmaceuticals, a pump mechanism is provided above a container having a cylindrical body with an open lower end surface. A movable bottom wall whose outer peripheral edge is fitted in a liquid-tight and ascending manner is provided in the lower portion of the inside of the body, and the upper portion of the bottom wall is filled with a cream-like material, and the cream-like material in the container body is discharged by the pump. Dispensing containers are known. or,
Conventionally, this type of container has a bottom cap fitted and fixed to close the opening at the lower end surface of the container body for the purpose of protecting the inside of the container. The bottom cap has, for example, a flat plate shape whose outer peripheral edge is fitted to the outer periphery of the lower end of the body of the container, and is formed by drilling a through hole for intake in the bottom wall (for example, a flat square 2). -11
1636).

[0003] Such a container is often used in a water place such as a washroom or a bathroom, so that water or the like is sucked from the through-hole of the bottom cap, and the water accumulates in the body of the container and becomes inconvenient. May occur.

[0004] The present invention proposes an excellent container for dispensing a creamy material which solves the above-mentioned disadvantages of the conventional container.

[0005]

In order to solve the above-mentioned problems, the container of the present invention has a cylindrical body 2 having an open lower end surface. A movable bottom wall 4 fitted so as to be fitted is provided, and
A pump mechanism is provided in a flow path that communicates the inside with the discharge hole,
Movable bottom wall 4 along with the creamy substance in the body 2
Is a cream-like material discharging container configured to rise upward, and a locking ridge 9 is provided at a lower end of the outer periphery from the lower surface of the container body 2.
The fitting cylindrical portion 8 is provided vertically, and the engaging ridge 18 provided on the lower portion of the inner peripheral surface is engaged with the locking ridge 9 from below to engage. And a bottom cap 12 having a bottom wall 14 extending from a lower end edge of the peripheral wall 13 to close a lower end opening of the container body. A vertical groove 10 is recessed above the stop rib 9, the upper end of the vertical groove 10 is opened above the bottom cap peripheral wall 13, and a through hole 11 communicating with the inside of the body 2 is formed in the lower part of the groove 10. It was configured to be installed.

[0006]

When the pump is operated to pour out the cream-like material in the container body 2 and when the movable bottom wall 4 is lifted, the outer surface of the fitting cylinder 8 vertically suspended from the lower end of the container body 2 is raised. Air is introduced into the container body 2 from the outside through a vertical groove 10 that is recessed and has an upper end opened above the peripheral wall 13 of the bottom cap 12 and a through hole 11 provided in the groove 10. The liquid on the body mounting surface is prevented from entering the body of the container.

Further, the fitting cylinder portion 8 of the container body and the peripheral wall of the bottom cap are provided.
The overhanging engagement between the ridges and the ribs 13 is performed by the vertical grooves 10
By performing the operation at the lower position, the missing portion of the locking ridge 9 is eliminated, so that the bottom cap 12 is hardly detached.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a container for dispensing a creamy substance. The container 1 has a container body 3 having a cylindrical body 2 with an open lower end surface,
A sliding bottom wall 4 having an outer peripheral edge fitted in a liquid-tight and ascending manner is provided in the lower portion inside the body portion 2. A press-down head 6 with a nozzle 5 is mounted on the upper part of the container body 3 so as to be vertically movable in an upwardly biased state.
The inside is fluid-tightly connected by a flow path (not shown), and a known pump mechanism (not shown) which operates by the vertical movement of the head is provided in the middle of the flow path.

Also, a thin fitting cylinder 8 is vertically attached to the outer peripheral lower end face of the container body 2 via a downward stepped portion 7, and is externally attached to the outer peripheral lower end of the fitting cylindrical section 8. A projecting locking ridge 9 is provided around. A vertical groove 10 extending from a predetermined position on the outer periphery of the fitting cylinder portion 8 above the locking ridge 9 to an upper end portion of the fitting cylinder portion is recessed. A through-hole 11 communicating with is provided.

A bottom cap 12 is fitted and fixed to the fitting cylinder 8. The bottom cap 12 has a bottom wall 14 in which a central portion is circularly recessed upward from a lower end edge of a cylindrical peripheral wall 13, and the bottom cap 12 is fitted on the inner periphery of the fitting cylinder portion 8 from a predetermined position on the upper peripheral edge of the bottom wall 14. The short cylindrical portion 15 to be combined, and the supporting cylindrical portion 16 are erected from the center of the upper surface of the bottom wall 14, respectively.
An auxiliary peripheral wall 17 is vertically provided from an outer periphery via an outward flange. An engagement ridge 18 is provided on the inner peripheral lower portion of the peripheral wall 8 so as to be able to climb over and engage with the locking ridge 9 of the container body 2. The height of the peripheral wall 8 is configured such that when the bottom cap 12 is attached to the container body 2, a gap 19 is formed as an opening between the upper edge of the peripheral wall 8 and the upper surface of the step 7. doing. Then, as shown in FIG. 2, the peripheral wall 13 is fitted to the outer periphery of the fitting tube portion 8 of the container body 3, and the inner periphery of the short tube portion 15 is fitted to the inner periphery of the fitting tube portion 8 for mounting. The outside is connected to the inside of the container body 2 from the gap 19 via the vertical groove 10 and the through hole 11.

In the container 1 constructed as described above, when the press-down head 6 is moved up and down, the cream-like substance in the container body 2 is discharged from the discharge hole of the nozzle 5 by the action of the pump. The movable bottom wall 4 is configured to rise inside the body 2 as the amount of the cream-like material in the container body 2 decreases. At this time, a gap is provided in the body 2 below the movable bottom wall 4.
Air is introduced from the outside through 19, the vertical groove 10, and the through hole 11,
The movable bottom wall 4 is configured to be smoothly raised.

The above members are all formed of a synthetic resin.

[0014]

As described above, since the container of the present invention has the above-described structure, even if the container is used in a water place, the opening is located at a position away from the side bottom wall. It is possible to prevent water or the like from entering the body as much as possible, and to solve the drawbacks of this type of conventional container.

[0015] Further, since the projecting ridges for engaging the bottom cap are engaged with each other under the longitudinal groove,
There is no missing portion due to the presence of the vertical groove in the locking ridge, so that the fitting and locking of the bottom cap can be performed reliably and hardly.
