Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container used for carrying various fluids.

[0002]

2. Description of the Related Art FIGS. 5A and 5B show a conventional container container, which is a container body 1 formed of a metal plate into a rectangular shape.
An opening 2 is provided in the upper end wall of the container, a cylindrical inner container 3 is housed in the container body 1, and a cylindrical inlet 4 protruding from the opening 2 to the outside of the container body 1 is provided at the upper end of the inner container 3. The inner container 3
Has a structure in which a valve-equipped nozzle 5 connected to the lower part of the container body 1 is led out to the outside of the container body 1 and a cushioning material 6 having a cushioning property is filled in the internal space of the container body 1. The fluid is injected into the inside of the container 3 and transported, and the fluid is carried out by opening the valve 7 of the nozzle 5 with the valve.

[0003]

By the way, in the container container as described above, the inside of the inner container 3 needs to be cleaned each time the fluid to be stored is changed.
In the structure in which the inner container 3 is housed, there is a problem that the cleaning is very difficult to perform and the cleaning cost is high because there is a recessed part inside.

Therefore, an object of the present invention is to provide a container container in which the inner bag for accommodating the fluid is detachably attached to the container body and the cleaning cost in the container can be reduced.

[0005]

In order to solve the above-mentioned problems, the invention of claim 1 has a cylindrical opening at the upper end of the body and a discharge tube at the lower end in the body of the container body. , An inner bag that can be inserted into and removed from the tubular opening, and a tubular portion that fits inside the tubular opening at the upper end of the inner bag; A flange portion mounted on the upper end and a discharge tubular portion that fits inside the discharge cylinder are provided at the lower end of the inner bag, and a nozzle with a valve is detachably attached to the discharge cylinder of the container body. .

According to a second aspect of the present invention, in the first aspect of the present invention, the bottom of the container body is formed on an inclined surface that descends toward the discharge cylinder located in the center, and the lower end of the discharge tubular portion of the inner bag is discharged. The structure is such that it projects from the lower end of the cylinder, and this protruding part serves as a seal between the discharge cylinder and the threaded portion of the valved nozzle.

Here, the inner bag is made of a flexible material such as polyethylene and has a size suitable for the inner shape of the container body. The fluid can be taken out by storing and opening the valve of the nozzle with valve.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, a container 11 is provided with a container body 12, an inner bag 13 which is detachably inserted into the container body 12, and a valve which is detachably attached to a lower portion of the container body 12. It is formed by a combination of nozzles 14.

The container body 12 is made of a metal material such as stainless steel, and has a cylindrical body 15 having a cylindrical opening 16 at the center of the upper end and a discharge tube 17 at the center of the lower end. The bottom portion of the is an inclined surface that descends from the outer peripheral portion toward the discharge tube 17, and the cylindrical opening 16 has a larger diameter than the discharge tube 17. The diameter and height of the body portion 15 of the container body 12 may be set according to the volume desired by the user, and the diameters of the cylindrical opening 16 and the discharge cylinder 17 may be set in the same manner. Nozzle with valve 1 on the outer surface of
A male screw 18 for screwing 4 together is provided.

The inner bag 13 is made of a material having flexibility, water resistance, and chemical resistance, such as polyethylene, and is formed in a cylindrical shape having a size and shape that can be exactly accommodated in the body portion 15, and a cylindrical shape at the upper end thereof. A tubular portion 19 that fits inside the opening 16 and a discharge tubular portion 20 that fits inside the discharge barrel 17 are provided at the center of the lower end.

At the upper end of the tubular portion 19, the tubular opening 1 is formed.
A flange portion 21 mounted on the upper end of the discharge tube 6 is provided around the discharge tube portion 20, and the discharge tubular portion 20 is dimensioned so as to protrude from the lower end of the discharge tube 17 by an appropriate length.

Since the inner bag 13 is flexible, it can be inserted into and removed from the body opening 15 of the container body 12 through the cylindrical opening 16, and a new inner bag can be exchanged for cleaning work. And the flange portion 21
Prevents the inner bag 13 from falling inside when the inner bag 13 is set in the container body 12, and when the lid member is fitted into the tubular opening 16, the flange 21 is attached to the outer periphery of the tubular opening 16. By folding it in, it will serve as a seal for the fitting portion.

When the valve-equipped nozzle 14 is screwed into the discharge tubular portion 20, the lower end of the discharge tubular portion 20 is engaged with the outer circumference of the discharge barrel 17 to seal the screwed portion.

The valve-equipped nozzle 14 screwed into the discharge cylinder 17 is formed by providing a screwing portion 22 to the discharge cylinder 17 at one end, a screwing connection portion 23 of a pipe at the other end, and a valve 24 in the middle. Various types such as the linear type shown in FIG. 1 and the L type shown in FIG. 4 are prepared for selection.

Although not shown, the container 1 for container
1, the container body 12 is housed in a protective frame and is held upright.

The container for container according to the present invention has the above-mentioned structure. The inner bag 13 is inserted into the body portion 15 of the container body 12 through the cylindrical opening 16 and the cylindrical portion 19 is formed.
The upper end flange portion 21 is placed on the opening portion 16, and the lower end discharge tubular portion 20 is fitted into the discharge cylinder 17.

Thereafter, if the nozzle 14 with the valve is attached to the discharge cylinder 17 with the lower end of the discharge cylinder 20 along the outer peripheral surface of the discharge cylinder 17, the container 11 for the container is assembled.
The fluid to be transported may be filled into the inner bag 13 from the tubular portion 19, and the inner bag 13 is shaped by the body portion 15 while being in close contact with the inner surface of the body portion 15.

The stored fluid can be taken out by opening the valve 24 of the valved nozzle 14, and the bottom surface of the body portion 15 and the bottom surface of the inner bag 13 which overlaps with the bottom surface are inclined surfaces which descend toward the discharge tube 17. Therefore, the whole amount of the fluid can be reliably taken out.

When transporting different types of fluids, the nozzle 14 with valve is removed, and then the cylindrical opening 16 is formed.
The inner bag 13 may be removed from the container body 12 at the portion, a new inner bag may be incorporated into the container body 12, and the washed nozzle 14 with a valve may be attached to the discharge cylinder 17. Inner bag 1 without fluid contact
By disposing 3 as a disposable, only the nozzle 14 with a valve needs to be cleaned, and the cleaning cost can be significantly reduced.

[0021]

As described above, according to the present invention, since the inner bag is housed in the container body so that the inner bag can be inserted and removed, the stored fluid does not come into contact with the container body. This can be done by simply changing the bag, and the cleaning cost of the container can be greatly reduced.

Further, since the bottom of the container body is inclined downward toward the discharge cylinder, the entire amount of the stored fluid can be reliably taken out.
