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

[0002]

[Prior art]

As a creamy material discharging container, a discharging pump is provided at the upper part of the container body, and the outer peripheral edge is fitted to the lower part inside the container body so as to be liquid-tight and slidably ascendable. 2. Description of the Related Art There has been known a creamy material dispensing container having a bottom wall and configured such that when the creamy material in the container is reduced by operating the above-described dispensing pump, the movable bottom wall rises accordingly.

Conventionally, in this type of container, when the movable bottom wall is fitted to the container body in the assembling process, the outer peripheral edge portion does not fit perfectly in a liquid-tight manner, and a minute gap is formed between the movable body and the peripheral wall of the container body. Or the movable bottom wall may be forcibly pushed into the inner wall of the container to cause damage or the like, resulting in a problem that the operation of the movable bottom wall is deteriorated. This tendency is particularly remarkable when the container has an elliptical shape in which the lengths of its long and short axes are not so different.

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

[0005]

In order to solve the above-mentioned problems, the container of the present invention is provided with a pouring pump 3 on the upper part of the container body 2 and a liquid-tight and slidably rising outer peripheral edge in the lower part of the container body 5. It has a movable bottom wall 4 fitted as possible, and when the above-mentioned pouring pump 3 is operated to dispense the creamy substance in the container body,
A container for dispensing cream-like material configured such that the movable bottom wall 4 rises as the amount of cream-like material in the container body 2 decreases, and is a bottomed cylindrical shape supported above the center of the upper surface of the bottom wall 14. The bottom cap 11 having the portion 15 erected and the fitting portion 21 whose outer peripheral edge is located at a predetermined distance from the bottom cap peripheral wall 13 in the bottom cap 11 and which is vertically provided from the back surface are placed above the support portion 15. Member consisting of a movable bottom wall 4 fitted so as to be able to escape to the bottom
12 is provided, and the bottom cap peripheral wall 13 of the member 12 is fitted to the outer peripheral lower end of the container body peripheral wall 5a from below, so that the peripheral edge of the movable bottom wall 4 slides on the inner peripheral lower end of the container body peripheral wall 5a. The bottom member 12 was mounted so as to be fitted up so as to be ascendable.

[0006]

When the bottom cap peripheral wall 13 of the bottom member 12 is fitted from below into the outer peripheral lower end of the body peripheral wall 5a of the container body 2 from the state of FIG. 3, the movable bottom wall 4 becomes the container body trunk peripheral wall of the bottom cap peripheral wall 13. 5
By being guided by the outer surface, it is inserted into an appropriate position in the container body 2 and its outer peripheral edge can be fitted into the inner peripheral lower part of the container body peripheral wall 5 without difficulty.

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

The cream-like material discharging container 1 of the present invention is provided with a discharging pump 3 at an upper portion of a container body 2 and a movable bottom having a liquid-tight and slidably fitted outer peripheral edge at a lower portion inside a body portion of the container body. When the cream 3 in the container 2 is poured out by operating the pump 3 and having the wall 4, the inside of the container body is reduced in pressure as the cream in the container 2 decreases, The structure is such that the movable bottom wall 4 is raised.

In this embodiment, the container body 2 has an elliptical cylindrical shape having an opening at a lower end surface formed by extending a torso top wall 5b from an upper end edge of an oval cylindrical torso peripheral wall 5a whose inner surface has the same shape from bottom to top. And a cylindrical mouth-and-neck portion 6 is erected from the center of the top wall 5b. The container body 5 is not limited to the elliptical cylindrical shape as in the above embodiment, but may be, for example, a cylindrical shape.

The pouring pump 3 can be used with any structure as long as it is used for this kind of container. In this embodiment, the pouring pump 3 is screwed to the outer periphery of the container body neck 6. The lower end cylinder 8 is hung down in the upper part of the container body 5, and a lowering head 10 with a nozzle 9 at the upper end is protruded upward and downward from the mounting cap 7 while being mounted.

In the container of the present invention, a bottom member 12 formed by fitting the movable bottom wall 4 to a bottom cap 11 is provided.
The container 1 is formed by fitting the bottom member 12 to the container body 2.

The bottom cap 11 has an elliptical cylindrical peripheral wall 13 which can be fitted to the outer periphery of the thin wall portion 5a1 formed on the lower part of the outer peripheral wall of the container body peripheral wall 5a. An elliptic cylindrical shape with a bottom end opening is formed, and an elliptical cylindrical supporting portion 15 as a supporting portion for supporting the movable bottom wall 4 is protruded from the center of the upper surface of the bottom wall 14. A circular window hole 16 is formed in the center of the bottom wall 14. On the peripheral edge of the upper surface of the bottom wall 14, an elliptical cylindrical short cylindrical portion 17 that can be fitted to the inner peripheral lower end of the container body peripheral wall 5a at a predetermined interval from the peripheral wall 13 is provided. . Further, on both sides of the inner surface of the support cylinder 15, projections 18, 18 penetrating vertically are respectively provided.

The movable bottom wall 4 has an elliptical cylindrical shape with the upper and lower parts projecting outward in the form of a skirt and a sliding portion capable of being fitted in a liquid-tight manner to the lower end of the inner surface of the peripheral wall 5a of the container body. 20 is extended from the peripheral edge of the bottom plate portion 19 in the shape of an elliptical plate, and a fitting tube portion 21 having an elliptical cylindrical shape as a fitting portion is vertically provided below the center portion of the back surface of the bottom plate portion 19 to be configured. ing. Further, on the left and right sides of the outer surface of the fitting cylindrical portion 21, there are vertically provided concave grooves 22, 22 into which the above-mentioned ridges 18, 18 are slidably fitted. Then, the bottom member 12 is formed by fitting the fitting tubular portion 21 into the support tubular portion 15 and fixing the fitting tubular portion 21 to the bottom cap 11.

The bottom member 12 constructed as described above is fitted from below the container body 2 to form the cream-like material discharging container 1.

In addition, the pump 1 in the cylinder 8 is operated by moving the press-down head 10 up and down in the cream-like material discharging container 1 constructed as described above.
The creamy substance in the container body 5 is sucked up from the lower end opening and is poured out from the nozzle 9 of the head 10. At this time, the inside of the container body 5 is reduced in pressure as the cream-like material in the container body 5 is reduced, and the movable bottom wall 4 is raised accordingly.

The above members are all made of synthetic resin. In the figure, reference numeral 23 denotes a rib provided on the upper surface of the bottom wall 14 of the bottom cap 11, and reference numeral 24 denotes a cap.

[0017]

As described above, in the container of the present invention, the movable bottom wall is fitted with the outer peripheral edge of the container to the inner surface of the container body in a liquid-tight manner. The movable bottom wall can be accurately mounted on the container body without inconvenience such as a minute gap being generated between the inner surface and the inner surface, and as a result, there is no possibility that the movable bottom wall will malfunction.

Another advantage is that a rib for positioning the movable bottom wall and the container is not required.
