Abstract

PURPOSE:To reduce the quantity of a residual liquid in the container when a pump type container is used, eliminate the annoyance to remove a residual liquid by opening a lid, and prevent the wastefulness such as the container is discarded while a residual liquid is still in it from happening. CONSTITUTION:On the bottom of a container main body 1 of a pump type container, a residual liquid reservoir part 4 with an upside down truncated cone shape is formed. For the structure, a suction port 3 for a suction tube 2 is made to be confronted to the central position of the residual liquid reservoir part 4 with a specified gap.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a pump type container,
In particular, the present invention relates to a technique effectively applied to, for example, a pump type container in which a cleaning liquid in a container body is sucked up by a pump.

[0002]

2. Description of the Related Art As a pump type container of this type, there is, for example, one shown in FIG.

That is, this pump type container sucks up the cleaning liquid in the container body 1a by a pump, and a suction tube 2a hangs down from a pump provided in a lid, and a suction port 3a of this suction tube is at the bottom of the container body 1a. It has a structure facing.

[0004]

However, in the conventional pump-type container described above, the bottom of the container body 1a, which the suction port 3a of the suction tube 2a faces, has a horizontal surface. There was a large amount of cleaning liquid that could not be sucked up by a pump, and the lid had to be opened to remove the contents each time, which was a problem.

Further, there is a problem in that the cleaning liquid is wasted because some people discard the container without noticing the residual cleaning liquid.

An object of the present invention is to provide a pump type container which can reduce the amount of the residual liquid in the container and can eliminate the trouble of opening the lid to discharge the residual liquid.

Another object of the present invention is to provide a pump type container capable of eliminating waste such as discarding the entire container while storing the residual liquid.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[0009]

Among the inventions disclosed in the present application, a brief description will be given to the outline of typical ones.
It is as follows.

The pump-type container of the present invention is a pump-type container in which a suction tube is hung from a pump provided on a lid, and a suction port of the suction tube faces the bottom of the container body. The residual liquid storage portion is formed at the bottom, and the suction port of the suction tube is opposed to the residual liquid storage portion with a predetermined gap.

In this case, the residual liquid storage portion may have a structure having an inverted truncated cone shape.

[0012]

According to the pump type container of the present invention, the residual liquid storage portion is formed at the bottom of the container body, and the suction port of the suction tube is opposed to the residual liquid storage portion with a predetermined gap. Therefore, the amount of residual liquid in the container can be reduced.

Therefore, it is possible to eliminate the trouble of opening the lid and discharging the residual liquid.

Further, it is possible to eliminate waste such as discarding the entire container while storing the residual liquid.

In this case, since the residual liquid storage portion has a structure having an inverted truncated cone shape, the suction port can easily be opposed to the central position of the residual liquid storage portion to further enhance the effect. it can.

Embodiment 1 FIG. 1 is a sectional view showing a pump type container which is Embodiment 1 of the present invention.

The pump type container in the first embodiment is applied to a cleaning liquid, and has a circular cross section.
have. A pump is built in the lid that covers the open end of the container body 1. The pump has a function of sucking up the cleaning liquid in the container body 1 by pushing the plunger by hand.

Further, the suction tube 2 is drawn from the pump.
The suction port 3 of the suction tube 2 faces the bottom of the container body 1. A residual liquid storage portion 4 is formed at the bottom of the container body 1. The residual liquid storage portion 4 has an inverted truncated cone shape, and the suction port 3 of the suction tube 2 faces the central position with a predetermined gap. It has a structure.

A mounting table 5 is adhered to the bottom of the container body 1. The mounting table 5 has a function of stably mounting the container body 1 having an inverted frustoconical bottom, and an opening of the mounting table 5. The end portion 6 and the raised bottom portion 7 are bonded to the bottom portion of the container body 1.

Next, the operation of the first embodiment will be described.

FIG. 2 is an explanatory view showing a manufacturing procedure of the pump type container of FIG.

When manufacturing the pump-type container having the above structure,
First, the container main body 1 having the inverted frustoconical bottom portion and the mounting table 5 are molded by injection molding.

Next, the mounting table 5 is adhered to the bottom of the molded container body 1 with an adhesive, and a lid with a pump is attached to the open end of the container body 1 by screwing.

When using the pump-type container manufactured in this way, the bottom of the container body 1 has an inverted truncated cone-shaped residual liquid storage portion 4.
Is formed, and the suction port 3 of the suction tube 2 is opposed to the center position of the residual liquid storage part 4, so that the residual liquid is stored in the central part of the residual liquid storage part 4, and therefore the residual liquid The amount can be reduced.

Therefore, it is possible to eliminate the trouble of opening the lid and discharging the residual liquid.

Further, it is possible to eliminate waste such as discarding the entire container while storing the residual liquid.

[0027]

[Embodiment 2] FIG. 3 is a sectional view showing a pump type container according to Embodiment 2 of the present invention.

The pump-type container of the second embodiment has substantially the same structure as that of the first embodiment, except that a cylindrical mounting portion 8 is integrally formed on the outer peripheral edge of the bottom of the container body 1. It was done.

With regard to the operational effects of the second embodiment, in addition to the operational effects of the first embodiment, the steps of molding and joining the mounting table of the first embodiment can be eliminated.

Although the invention made by the present inventor has been specifically described based on the embodiments, the invention is not limited to the embodiments and various modifications can be made without departing from the scope of the invention. Needless to say.

For example, in the above embodiment, the case where the inverted frustoconical shape is formed on the bottom of the container body has been described.
Not limited to this, it is also possible to form an inverted truncated pyramid shape on the bottom of the container body so as to correspond to the rectangular cross-section of the container body.

In the above description, the invention mainly made by the present inventor has been described with respect to the pump type container for the cleaning liquid, which is the field of application which is the background of the invention, but it can be applied to the pump type container for the chemical liquid.

[0033]

The effects obtained by the typical ones of the inventions disclosed in the present application will be briefly described as follows.
It is as follows.

(1). Since the residual liquid storage portion is formed at the bottom of the container body and the suction port of the suction tube is opposed to the residual liquid storage portion with a predetermined gap, the residual liquid inside the container The amount of liquid can be reduced.

(2). Due to the effect of the above (1), it is possible to eliminate the trouble of opening the lid and discharging the residual liquid.

(3) Due to the effect of the above (1), it is possible to eliminate waste such as discarding the entire container while storing the residual liquid.

(3) In the case of (1) above, since the residual liquid storage portion has a structure of an inverted truncated cone shape, the suction port is easily opposed to the center of the residual liquid storage portion to Can be further increased.
