Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a quantitative extraction container capable of extracting a fixed amount of a fluid or semi-fluid-like contained object such as cream.

<Prior Art> Conventionally, as a quantitative extraction container for extracting a fixed amount of a fluid or semi-fluid-like contained material such as cream and pomade,
For example, those disclosed in Japanese Utility Model Laid-Open No. 60-38270 and Japanese Utility Model Laid-Open No. 59-153874 are known.

In each of these quantitative extraction containers, when the push button provided on the upper end of the container body is pressed, the valve opens in conjunction with the push button, the contents in the container body are extracted from the extraction port, and the push button When the pressure is restored, a negative pressure is generated in the container body, and the negative pressure causes the bottom lid of the container body to rise corresponding to the extraction amount of the contained object, and the movement stroke of the push button is set constant. As a result, the contained items can be extracted in fixed amounts.

<Problems to be solved by the invention> In containers for cream, toothpaste, pomade, etc., normally, when the contained cream, etc. is consumed, it is discarded, so it is necessary to reduce the cost of the container as much as possible. Yes, the same thing is required even when a quantitative extraction container is used.

However, in the quantitative extraction container, a spring is used to return the push button after extracting the contents,
Further, since a mechanism that opens and closes the valve in conjunction with the push button is adopted, the number of parts is large, the structure is complicated, the cost is high, and there is a problem that the above requirements cannot be met.

The present invention has been made to solve the above-mentioned problems of the prior art. The purpose of the present invention is to reduce the number of parts as much as possible, simplify the structure, and significantly reduce the manufacturing cost. It is to provide a quantitative extraction container capable of

<Means for Solving the Problems> In order to achieve the above object, in the present invention, a mouth of a container body filled with a fluid or semi-fluid content has an extraction port and is pushed into the container body. At this time, a stopper member for extracting a certain amount of the contained matter is provided, and a stopper member that covers the stopper member and is pushed into the container body at the time of mounting on the mouth portion side of the container body. An upper lid member that pulls up and returns to the original position is detachably attached, and further, a bottom lid that moves to the mouth side corresponding to the extracted amount of the stored contents is provided at the bottom of the container body. It is characterized by that.

<Operation> According to the above means, when the upper lid member is removed and the stopper member is pushed into the container body by a certain amount, a certain amount of the fluid or semi-fluid-like contained substance is extracted from the extraction port provided in the stopper member. . Then, when the upper lid member is mounted again, the stopper member pushed by the upper lid member is pulled up and returns to its original position, while the negative pressure generated in the container main body due to the return of the stopper member causes the bottom lid to close. It moves to the mouth side of the corresponding to the extraction amount.

Here, the plug member performs a function similar to that of a conventional push button and has a simple structure. Further, the upper lid member not only covers the stopper member, but also serves as an opening / closing valve for the extraction port and a return member for the stopper member. Structurally, for example, a protrusion for closing the extraction port is provided to form the opening / closing valve and This is a simple structure in which a threaded portion that is screwed into a threaded portion provided on the outer circumferential surface of the plug member is provided on the circumferential surface to serve as a restoring means.

Therefore, it is possible to reduce the number of parts and simplify the structure.

FIG. 4 is a side view, and FIG. 4 is a perspective view in which a plug member is partially cut away.

In the figure, reference numeral 1 is a container body, which is formed of, for example, a transparent synthetic resin into a substantially cylindrical shape, so that a fluid or semi-fluid-shaped container A filled with cosmetics or the like can be seen through. There is.

A flange (shoulder) 3 protruding inward is provided over the entire circumference of the upper end opening 2 of the container body 1, and a stopper member 4 made of synthetic resin is secured in a state of being prevented from coming off by the flange 3. It is fitted in the upper end opening portion 2 in an airtight state so as to be movable in the axial direction.

As shown in FIG. 4, the stopper member 4 is provided on a bottomed cylindrical base portion 5 provided with a seal portion 5a having a substantially C-shaped cross section which is in sliding contact with the inner peripheral surface of the container body 1 and maintains an airtight state. In addition, a bottomed cylindrical extraction part 6 having an extraction port 6a at the center of the upper end surface is integrally connected, and the inside is hollow and communicates with the inside of the container body 1. The fluidized or semi-fluid-like contained material A filled in is extracted from the extraction port 6a by a predetermined amount.

Here, the continuous portion 6b of the extraction portion 6 with the base portion 5 has a polygonal cross section, and is fitted into the same polygonal mouth portion 3a surrounded by the flange 3 as described above. 4 does not rotate with respect to the container body 1. It should be noted that either one of the continuous portion 6b and the mouth 3a is provided with a convex portion and the other is provided with a concave portion with which the convex portion engages, or the continuous portion 6b is provided.
The mouth portion 3a may be formed to have an elliptical cross section so that the plug member 4 does not rotate with respect to the container body 1.

Further, the outer peripheral surface of the extraction portion 6 is provided with a screw thread 6c having a substantially trapezoidal cross section as a screw portion, and a protrusion 6d (see FIG. 2) at a boundary position between the outer peripheral surface and the continuous portion 6b. Is provided. When the stopper member 4 is pushed into the container body 1, the protrusion 6d comes into contact with the flange 3 and the stopper member 4
And serves as a stopper that regulates the movement of the plug member 4, and keeps the movement stroke S (see FIG. 2) of the plug member 4 constant. Instead of the protrusion 6d, the screw thread near the continuous portion 6b
The 6c part may be used as a stopper.

In addition, at the upper end of the container body 1, a cap shape is provided in which a protrusion 7a that engages with the extraction port 6a is provided at the center of the inner surface of the upper end, and a screw thread 7b that is screwed into the screw thread 6c is provided on the inner peripheral surface. The upper lid member 7 is detachably attached.

The upper lid member 7 has a function as an opening / closing valve that covers the plug member 4 and closes the extraction port 6a with the protrusion 7a.
It has a function as a returning means for pulling up the stopper member 4 pushed into the container body 1 when the container body 1 is mounted and returning it to the original position.

That is, when the upper lid member 7 is screwed into the stopper member 4 pushed into the container body 1, the upper lid member 7 is screwed with this screwing.
Moves downward with respect to the plug member 4, and the upper cover member 7 is further rotated (screwed) after the lower end surface of the upper cover member 7 contacts the flange 3, the upper cover member 7 cannot move any more. However, the plug member 4 is pulled up by the screw action of the screw threads 6c and 7b.

A packing material 7c is attached to the inner surface of the upper end of the upper lid member 7.

A bottom lid 8 is fitted on the bottom of the container body 1. The bottom lid 8 is formed in a substantially convex shape so as to project inward of the container body 1 and has a substantially C-shaped cross section over the entire circumference thereof in an airtight state on the inner peripheral surface of the container body 1. The seal portion 8b is provided so as to be slidably contacted with each other. When a negative pressure is generated in the container body 1 by pulling up the plug member 4, the negative pressure causes the container body 1 to rise.

 Next, the operation of the quantitative extraction container of the above embodiment will be described.

In the state shown in FIG. 2 in which the upper lid member 7 is removed from the quantitative extraction container in which the contents A such as cosmetics are filled in the container body 1 and the stopper member 4 without a gap, the stopper member 4 is placed in the container body 1. When pushed in, the stopper member 4 moves downward by the movement stroke S as shown in FIG. As a result, the container body 1
The internal pressure of the inside increases, and due to this internal pressure, the contents A such as cosmetics are contained.
Is extracted from the extraction port 6a. At this time, since the movement stroke S of the plug member 4 is set to be constant, the extraction amount is constant.

When the upper lid member 7 is put on the stopper member 4 after the contents A have been extracted, the protrusion 7a is fitted into the extraction port 6a and closed. Then, when the upper lid member 7 is screwed into the plug member 4, the upper lid member 7 is inserted into the plug member 4.
And the lower end surface of the upper lid member 7 contacts the flange 3 of the container body 1. In this state, the upper lid member 7 does not move any further, but if it is screwed in further, the thread
The stopper member 4 is returned to the position shown in FIG. 1 by pulling up the stopper member 4 by the amount of pushing (moving stroke S) by the screw action of 6c and the screw thread 7b.

When the stopper member 4 is returned, in the process of this return, the contents A
And the volume between the plug member 4 and the bottom lid 8 whose internal volume has once decreased is about to expand, which causes a negative pressure in the container body 1, and this negative pressure corresponds to the amount of extraction and the bottom. The lid 8 is sucked up.

By repeating this operation, a fixed amount is extracted from the inside of the container body 1 until the contained material A disappears.

In this way, the plug member 4 itself has a function similar to that of a conventional push button, the projection 7a of the upper lid member 7 has a function similar to that of a conventional on-off valve, and the upper lid member 7 has the plug member 4 in the original position. By providing a function similar to that of the conventional return means (spring) for pulling up to 1, the number of parts can be reduced and a simple structure can be achieved, and the manufacturing cost of the quantitative extraction container can be significantly reduced.
