[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container which can be used for various purposes, such as storing a high-viscosity liquid such as a paste or an adhesive.

[0002]

2. Description of the Related Art Conventionally, as containers for storing high-viscosity liquids such as adhesives, containers made of cardboard or cardboard, plastic containers, metal containers, and the like have been proposed.

[0003]

However, containers made of cardboard and containers made of corrugated cardboard are inexpensive to manufacture, but have drawbacks in water resistance, waterproofness, and moisture resistance. Was also significantly inferior.

[0004] For example, when the contents are put in a container, if the strength of the box itself is low, the weight of the container or the edge portion where the strength is weaker than the other parts of the box during transportation, especially the weight of the container is emphasized. Such a portion is easily dented or damaged. Therefore, there is a case where the contents are leaked due to an impact during transportation.

[0005] A container in which a bag is inscribed on the inner periphery of a paper container has also been proposed. Such a container may be used for storing a substance having a low viscosity. When storing materials with high viscosity, it is difficult to collect the viscous substance attached to the inner peripheral wall of the bag itself without removing the bag itself or the stored material, so it is economical. The losses were quite large.

On the other hand, plastic containers and metal containers have improved strength, as well as water resistance, waterproofness, and moisture resistance, but require expensive manufacturing dies during the manufacturing process. Further, the cost of the mold material itself is high, so that the manufacturing cost has risen remarkably.

A container in which a blow-molded container made of polyethylene or the like is inserted into the inner wall of a cardboard box has also been proposed. However, when a highly viscous substance is contained, it is extremely difficult to take it in and out. However, disposal after use is troublesome and has a great effect on environmental problems.

In order to solve these problems, cardboard or cardboard is used as the member itself, but an inner container and an outer container are formed using a container laminated with a synthetic resin or a member impregnated with a synthetic resin. Attempts have been made, but the water resistance and waterproofness are improved, but the strength is almost the same as that of cardboard or cardboard, so that the inner box is damaged during use and the contents leak out.

Therefore, the present invention has sufficient strength, is inexpensive to manufacture, and has a simple manufacturing process.
It is an object of the present invention to obtain a container which is excellent in water resistance, waterproofness and moistureproofness, and which is easy to handle even when storing a high viscosity material such as an adhesive.

[0010]

In order to achieve the above object,
The invention according to claim 1 of the present invention is a box made of a cardboard-like member made of resin, a lid-shaped packaging member arranged on the box made of a cardboard made of paper, and at least made of a cardboard made of paper. A container having a saucer-type packaging member that covers the bottom of the box and a locking member that tightens the two packaging members.

According to a second aspect of the present invention, in the container according to the first aspect, the box is formed by heat-sealing or bonding with an adhesive.

[0012]

[0013]

The container of the present invention comprises a box made of a cardboard-like member made of a resin, a lid-shaped packaging member made of a cardboard made of paper placed on the top of the box, and at least the cardboard made of a cardboard made of paper. Since it has a saucer-type packaging member that covers the bottom of the box and a locking member that tightens the two packaging members,
It is possible to make a high strength container.

When the container containing the contents is transported, the weight of the container mainly hangs on the portion where the locking member and the box are in contact with each other. However, the lid-type packaging member made of cardboard made of paper and the tray-type packaging member are Since it absorbs an external impact to the box, it is possible to prevent the contents from leaking due to being dent by the weight of the container itself during transportation and being damaged by strong impact.

Further, the two packaging members can absorb the external impact on the container as described above and increase the strength of the container during storage. For example, if the contents are stored in this container and stacked in many layers, the upper part of the box is bent by its weight, the box is deformed, and in the worst case, the box may be damaged. The container of the present invention, by providing a packaging member made of corrugated cardboard, can particularly prevent the upper and lower parts of the box body from being bent and also prevent subsequent damage.

Further, since the box housing the contents is made of a resinous cardboard-like member, the surface is smooth and slippery. Therefore, by arranging the packaging member made of cardboard made of paper, slippage due to the material of the box itself can be suppressed, so that the locking member can be prevented from slipping out of the box, and workability during transportation is good.

Further, the saucer-type packaging member may be any as long as it covers at least the bottom of the box. For example, it may be configured to cover the entire side surface of the box, or may be configured to cover a part of the box. When the entire side surface of the box is covered, the entire body including the side surface of the box can be reinforced.
It is possible not only to prevent subsequent damage, but also to make the container strong against external impact. In addition, if the container is provided with a saucer-type packaging member that only covers the lower part of the box body depending on the purpose of use, it is relatively inexpensive and economical.

Further, the container of the present invention has a water-resistant, water-proof and moisture-proof property because the box for storing the contents is made of a resin-made cardboard-like member. And the box is hard to break even if the contained substance is of high viscosity such as an adhesive.

Therefore, this box can be accommodated even when a highly viscous substance such as an adhesive comes out. If an appropriate opening is provided in the upper part, the work such as putting in and out with a spatula can be easily performed. It can be done efficiently and economically.

Further, since the box made of the resin-made cardboard-like member is assembled and joined by heat fusion or adhesion, the manufacturing process is simple, the member is strong without deteriorating the strength of the member, and the fusion is performed. It is also excellent in water resistance, waterproofness and moisture proofness of a wearing or bonding part. In addition, an expensive mold such as a manufacturing die is not required, and the manufacturing cost can be significantly reduced as compared with a plastic container or a metal container.

The resin-made corrugated cardboard-like member is a member in which a core member having a resilient structure and a liner member having a flat surface and many front and back surfaces are bonded together. For example, as shown in FIG. 3 , which will be described later, a structure in which an inner member 12 serving as a core member is interposed between a flat surface liner 10 and a back surface liner 11 is known.

This resin-made corrugated cardboard-like member is formed by joining an inner part 12, which is partially embossed in a columnar shape, between a front surface liner 10 and a back surface liner 11 on a flat plate, thereby forming air inside the cylinder. Space 13 that enclosed
And a three-layer structure in which a space 14 through which air passes is formed. These air spaces 13 and 14 ensure sufficient strength as a resin-made cardboard-like member, and can also achieve a heat-retaining and cooling effect and prevent freezing.

Therefore, by forming the box with such a resinous cardboard-like member, the strength of the content storage container is sufficiently maintained, and the resin inner and the internal air space are water-resistant and waterproof. The properties and moisture resistance are also incomparable with those made of paper. In addition, since the inner surface is flat, the contents can be smoothly taken out. For example, even if a high-viscosity adhesive or the like is stored, the contents can be taken out with a spatula or the like.

Of course, processing these to form a box can be performed very easily by bonding the bottom surface to the side wall by heat welding or an adhesive.

The structure of the resin-made cardboard-like member is not limited to that shown in FIG. 3 described later, and any other structure having the same effect may be used. Things. The material is not particularly limited, but polyethylene, polypropylene, or the like is preferably used.

FIG. 1 is an external view of an embodiment of the container of the present invention. A lid-shaped packaging member 2 is disposed on the top of a box 1 made of a resin-made cardboard-like member, a saucer-type packaging member 3 is disposed on the bottom, and a wide tape 4 is used for the two packaging members. Is tightly fixed to the box.

FIG. 2 is a longitudinal sectional view of the container of the present invention.
A circular hole 5 for taking in / out the contents is formed in the upper surface of the box 1, and the hole 5 is sealed with an adhesive sheet (not shown) after the contents are stored.

In this embodiment, a circular opening is provided as an embodiment for taking in and out the contents. However, depending on the application, for example, the upper part may be formed in another shape such as an openable lid. Good. Further, the sealing means is not limited to the pressure-sensitive adhesive sheet, and another means such as a resin cap may be used.

FIG. 3 is an explanatory view showing an example of a cardboard-like member of a resin box used in the present invention. It has a three-layer structure in which an inner 12 is interposed between a front liner 10 and a back liner 11 on a flat plate. Thereby, the space 13 in which the air is sealed in the cylinder is provided.
Thus, a space 14 through which air passes is formed.

[0030]

[Effects of the Invention] In the container of the present invention, at least the packaging members arranged at the upper and lower parts of the box absorb external shocks to the box, and are depressed by strong impact during transportation and the weight of the container itself. Leakage of contents due to damage can be prevented.

Further, a packaging member made of corrugated cardboard is provided at least at the upper and lower parts of the box body to reinforce the flexible portion to form a high-strength container, and to prevent slippage due to the material of the box body itself. The member can be prevented from slipping out of the box, and workability during transportation is good.

Further, the box made of the resin-made cardboard-like member of the container of the present invention is excellent in water resistance, waterproofness and moisture resistance, and is extremely robust, and can accommodate a liquid of high viscosity.

Further, when the contained substance is a substance having a high viscosity such as an adhesive, when the adhesive or the like adhering to the inner wall surface is collected with a spatula or the like, the inner surface is flat. The contents can be taken out smoothly and the work can be easily performed, which is economically advantageous.

In addition, the raw material cost is low, and the manufacturing process is simple and no expensive mold such as a manufacturing die is required, so that the manufacturing cost can be greatly reduced. Furthermore, since the component itself of the box has a three-layer structure, it is possible to achieve a heat-retaining and cooling effect and prevent freezing.
