Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid transport container.

[0002]

2. Description of the Related Art Metal containers are widely used for transporting liquids such as paints and oils to predetermined locations, and for transporting foods such as honey and syrup. Such a metal container is generally discarded after being used once because of the troublesome cleaning.

[0003] In recent years, from the viewpoint of resource protection and waste disposal, a plastic bag has been used as an inner container instead of a conventionally used metal container, which has been further housed in an outer container such as a cardboard box. So-called back-in-box type containers are being adopted. However,
When the cardboard box is used as the outer container, the cardboard box is eventually disposed of, which increases the amount of dust. In addition, when the cardboard box is exposed to water or the like, it becomes stains and appears on the surface, so that not only is it undesirable in appearance,
If a sharp object is hit, the inner container containing the liquid will be broken and the contents will leak. Furthermore, such cardboard boxes are easily crushed when stacked in multiple stages, and are unsuitable for transporting in multiple layers.

On the other hand, as the outer container, a container made of a synthetic resin may be adopted as shown in FIG. 6 instead of the cardboard box. (Refer to Japanese Patent Application Laid-Open No. Hei 8-26338.) This liquid transport container 1 has a foldable synthetic resin container 12 in which an inner liquid bag 11 formed of a flexible sheet is foldable.
Housed within. In the liquid transport container 1, the lid 13 is rotated from the state shown in the drawing to close the opening, and the opening 11a formed in the liquid bag 11 is
By inserting the container 1 into the outlet 13e formed in the lid 13, further removing the cap 11b attached to the distal end, and tilting the container 1, the liquid content can be poured out.

[0005]

By the way, in the liquid carrying container 1 using the synthetic resin container 12 as the outer container as described above, for example, the lid 13 is opened to take out the inner liquid bag 11. Then, since the liquid bag 11 is attached to the lid 13, the liquid bag 11 is lifted up together with the lid 13. Therefore, in the conventional liquid transport container 1, the operation for replacing the liquid bag 11 is complicated,
There was a problem that it was troublesome.

Further, in this liquid transport container 1, since there is no particular portion for supporting the synthetic resin container 12 when the liquid is poured out, the operator can turn the posture upside down by attaching a hand to the bottom of the container. However, since the liquid is poured out in that position, there is a problem in that the work for discharging the contents is poor. The present invention has been made in view of such a problem, and it is possible to satisfactorily replace the inner bag when the inner bag is empty, and to easily perform the operation for discharging the liquid. It is intended to provide a container for use.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a flexible inner bag formed with a protruding mouth for filling and discharging a fluid content. An outer container made of a synthetic resin that houses the inner bag so that the inner bag can be taken in and out, wherein the outer container sets the inner bag in a storage state or a discharge state of contents. It is characterized by comprising a main body and a lid detachably attached to the outer container main body, and a discharge hole for discharging the contents is formed in the outer container main body.

According to the present invention having such a configuration, since the outer container is formed of a synthetic resin, the outer container can be used repeatedly. Therefore, the amount of waste to be discarded can be reduced. Further, it is preferable that the outer container main body is provided with a lock means for fixing the mouth portion immovably when the inner bag is set in a discharge state.

Thus, the posture of the inner bag set to discharge the contents can be stabilized. further,
Preferably, the locking means is a flange formed on the mouth. With such a configuration, the inner bag can be easily set on the outer container body.

Preferably, a handle is provided on the outer container body. With such a configuration,
It is convenient for carrying, and can hold the handle when discharging, thereby improving workability. Further, it is preferable that a reinforcing rib is formed around the discharge hole.

[0011] Thus, it is possible to reduce a decrease in the strength of the outer container body due to the provision of the discharge hole. Preferably, the discharge hole is provided with a lid member for selectively opening the discharge hole. With this configuration, the inner bag is not touched from the outside when the inner bag is conveyed or the like, so that a sealing function can be provided.

The vinyl inner bag 21 is preferably cylindrical or rectangular, but the shape is not particularly limited. One side wall of the inner bag 21 is provided with an opening 22 for filling and discharging the liquid. A flange 24 is formed on the peripheral surface of the mouth 22. Such inner bag 2
1 can be folded compactly when not in use, and can be filled or discharged from the mouth 22 during use, but a cap is attached to the mouth 22 after filling. Then, such an inner bag 21 is generally discarded as it is once used.

On the other hand, the outer container 25 comprises an outer container main body 26 and a lid 28 which is detachably attached to the opening 27 of the outer container main body 26. The outer container main body 26 and the lid 28 are Both are formed from a synthetic resin such as polypropylene so that they can be used repeatedly. A pair of opposed side walls 31 of the outer container body 26
The pocket portions 29 are formed at predetermined intervals on the opening end surfaces of the openings a and 31b. On the other hand, claws 30 are formed at a predetermined interval on a pair of side walls 23a and 23b of the lid 28 facing each other. In the ceiling of the lid 28, gripping concave portions 43a and 43b for lifting by hand are formed. When the lid 28 thus formed is aligned with the opening 27 of the outer container main body 26 from above, and the lid 28 is further slid slightly in the direction of arrow A from this state, the claw 30 is attached to the side wall of the pocket 29. Since the cover 28 is engaged with the formed hole (not shown), the lid 28 can be tightly locked to the outer container main body 26. In this state, the lid 28 does not come off even if the posture of the outer container body 26 is turned upside down.

On the other hand, on the side wall 31a of the outer container body 26,
A discharge hole 32 for discharging the contents is formed at a position above the discharge hole 32. As shown in FIG. 3, the discharge hole 32 is formed as a daruma hole having a shape in which a large-diameter hole 32a and a small-diameter hole 32b are continuous. Further, a rib 33 whose lower side is curved in a U-shape is formed on the side wall 31a so as to cover the periphery of the discharge hole 32. The strength around the discharge hole 32 is reinforced by the rib 33.

First, the inner bag 21 is loaded with a paint, for example, as a content. Then, as shown in FIG. 4, with the cap 37 attached to the mouth 22, it is housed in the outer container main body 26. Further, the lid 2 is attached to the outer container body 26.
8, the cover 28 is slid in the direction A as shown in FIG. 1 so that the cover 28 is not easily detached from the outer container body 26.

In this manner, the storage state of the transport container 20 containing the paint therein is established. After being transported to the predetermined location, the lid 28 is removed from the outer container body 26 by sliding in the direction opposite to the direction A. Then, the inner bag 21 is taken out of the outer container body 26. When the inner bag 21 is taken out, the discharge hole 32 is exposed by rotating the shielding plate 41 covering the discharge hole 32 of the outer container body 26 around the hinge 45 as a fulcrum. Then, the cap 37 is removed from the mouth 22 of the inner bag 21, and the mouth 22 is inserted into the discharge hole 32. At this time, if the flange 24 of the mouth portion 22 is guided from the large-diameter hole 32a of the discharge hole 32 into the small-diameter hole 32b and locked on the wall portion of the small-diameter hole 32b, as shown in FIG. Lock means B is provided between the outer container body 26 and the outer container main body 26 so as to immovably fix the inner bag 21 to the discharge hole 32. By this locking means B, the attachment of the inner bag 21 to the outer container main body 26 is ensured.

Thereafter, the lid 28 is reattached to the outer container main body 26, whereby the discharging posture of the inner bag 21 is established. In such a transport container 20, the handle 40 can be lifted by hand or can be transported. In addition, if the outer container main body 26 is inclined obliquely by catching the hand on the holding concave portion 43a of the lid 28, the liquid material can be easily poured out from the mouth portion 22. Also, after pouring,
To remove the inner bag 21, the lid 28 is attached to the outer container body 2.
