Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container that can be used for various purposes including containing a high-viscosity liquid such as a sizing agent and an adhesive.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as containers for storing high-viscosity liquids such as adhesives, containers made of cardboard or corrugated paper, plastic containers, and metal containers have been proposed.

[0003]

[Problems to be solved by the device]

 However, although the container made of cardboard and the container made of corrugated paper have low manufacturing costs, they have drawbacks in water resistance, waterproofness, and moisture resistance, and are significantly inferior in strength.

For example, if the strength of the box itself is weak when the contents are put in the container, the edge portion, which is weaker in strength than other parts of the box, and the weight of the container are important during transportation. Such parts are easily dented or damaged. Therefore, the product may be damaged by the shock during transportation and the contents may leak out.

Further, a container in which a bag body is inscribed on the inner circumference of a paper container has been proposed, but such a container is suitable for accommodating a substance having a low viscosity, but a viscous substance such as an adhesive is used. In the case of storing a substance with a high content, the bag itself may come off together with the stored items, and it is difficult to collect all of the viscous substance adhering to the inner wall surface of the bag cleanly. Loss was quite large.

On the other hand, a plastic container or a metal container has not only strength but also improved water resistance, waterproofness, and moisture resistance, but an expensive manufacturing die is required in the manufacturing process. In addition, since the die material cost itself is also high, the manufacturing cost has risen significantly.

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, but when a highly viscous substance is contained, it is extremely difficult to take it in and out. Moreover, disposal after use was troublesome and had a great impact on environmental problems.

In order to solve these problems, as the member itself, cardboard or corrugated cardboard is used, but a container laminated with a synthetic resin or a member impregnated with a synthetic resin is used to form an inner container or an outer container. Although water resistance and waterproofness were improved, the strength was almost the same as that of thick paper or cardboard, so the inner box was damaged during use and the contents leaked out. .

Therefore, the present invention has sufficient strength, low manufacturing cost, simple manufacturing process, excellent water resistance, waterproofness and moisture resistance, and high adhesiveness. The purpose is to obtain a container that is easy to handle even if it contains a viscous material.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a box body made of a cardboard-like member made of resin, and a lid-type packaging member arranged on the upper part of the box body made of paper cardboard. Provided is a container including a saucer type packaging member which is made of paper corrugated cardboard and covers at least the bottom of the box body, and a locking member which tightens two packaging members.

A second aspect of the present invention is the container of the first aspect, wherein the box body is formed by being joined by heat fusion or an adhesive.

Further, the invention according to claim 3 is the container according to claim 1 or 2, wherein the resin-made cardboard-like member has an inner core member interposed between a front surface liner and a rear surface liner. It has a three-layer structure in which it is joined together.

[0013]

[Action]

 The container of the present invention comprises a box made of a resin-made cardboard-like member, a lid-type packaging member made of a paper cardboard arranged on the upper part of the box, and at least the box made of a paper cardboard. Since the tray-type packaging member that covers the bottom of the body and the locking member that tightens the two packaging members are provided, it is possible to obtain a container having high strength.

When the container containing the contents is transported, the weight of the container is predominantly applied to the portion where the locking member and the box contact each other, but the lid-type packaging member and the saucer-type packaging member made of paper corrugated cardboard are used. Since it absorbs external shocks to the box, it is possible to prevent the contents from leaking out by being dented by the weight of the container itself during transport or damaged by a strong shock.

Further, the two packaging members can absorb the external impact on the container as described above and can increase the strength of the container during storage. For example, if the containers are stacked in multiple layers while containing the contents, the upper part of the box may be bent due to its weight, and the box may be deformed, and in the worst case, may be damaged. The container of the present invention is provided with the packaging member made of corrugated cardboard, so that the upper and lower portions of the box can be prevented from being bent and the subsequent damage can be prevented.

Further, since the box for accommodating the contents is made of a resinous corrugated board-like member, the surface is smooth and slippery. Therefore, by arranging the packaging member made of paper corrugated board, it is possible to prevent slippage due to the material of the box body itself, so that the locking member can be prevented from slipping out of the box body, and workability during transportation is good.

Further, the saucer type packaging member may cover at least the bottom of the box body. For example, the side surface of the box may be entirely covered, or a part of the box may be covered. By covering all the side surface portions of the box body, it is possible to reinforce the whole body including the side surface portions of the box body, so that it is possible to prevent the box body from bending and to prevent subsequent damage, The container can be strong against external shocks. Further, depending on the purpose of use, a container provided with a tray-type packaging member that only covers the lower part of the box is relatively inexpensive and economical.

Further, in the container of the present invention, since the box body for containing the contents is made of a resin-made cardboard-like member, it is excellent in water resistance, waterproofness and moisture resistance, and of course it is made of paper. It is so strong that it is incomparable to other things, and even if the substance contained is a highly viscous substance such as an adhesive, the box is unlikely to break.

Therefore, this box is capable of accommodating even a highly viscous substance such as an adhesive, and if a proper opening is provided in the upper part, work such as taking in and out with a spatula can be easily performed. It is possible to do so, and it is advantageous both efficiently and economically.

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

The cardboard-like member made of resin is a member in which a core member having an elastic structure and a plate-like liner member covering the front surface or the front surface of the core member are bonded together. For example, as shown in FIG. 5 which will be described later, it is known that a flat plate-shaped front surface liner 10 and a back surface liner 11 are joined together with an inner member 12 serving as a center member interposed therebetween.

The resin-made corrugated board-like member is formed into a cylinder by joining the inner cylinder 12 partially embossed into a cylindrical shape between the front surface liner 10 and the back surface liner 11 on a flat plate. It has a three-layer structure in which a space 13 in which air is sealed and a space 14 in which air passes are formed. These air spaces 13 and 14 ensure sufficient strength as a resin-made corrugated board-like member, and can also provide a heat retention / cooling effect and freeze prevention.

Therefore, by constructing the box body with such a resinous corrugated board-like member, the strength as a container for containing contents is sufficiently maintained, and the resin inner, the internal air space, etc. provide water resistance, The waterproof and moisture-proof properties are not comparable to those made of paper. In addition, since the inner surface is flat, the contents can be taken out smoothly. For example, even if a high-viscosity adhesive is stored, the contents can be taken out neatly with a spatula.

Of course, it is extremely easy to process these to form a box body by heat-sealing the bottom surface to the side wall or adhering it with an adhesive.

The structure of the resin-made corrugated board-like member is not limited to that shown in FIG. 5 described later, and another structure may be used as long as it has the same effect. It is a thing. The material is not particularly limited, but polyethylene, polypropylene or the like is preferably used.

[Effect of device]

 In the container of the present invention, at least the packaging members arranged on the upper and lower parts of the box absorb the external shock to the box, and the container is dented or damaged due to the strong shock during transportation or the weight of the container itself. It can prevent things from leaking.

In addition, since a corrugated cardboard wrapping member is provided at least on the upper and lower parts of the box body to reinforce the flexible portion to form a high-strength container, it is possible to suppress slippage due to the material of the box body itself. The locking member can be prevented from slipping out of the box, and workability during transportation is good.

Further, the box body made of the resin-made corrugated board-like member of the container of the present invention is excellent in water resistance, waterproofness and moisture resistance, and is extremely robust and capable of containing a high-viscosity liquid.

Further, when the substance contained is a highly viscous substance such as an adhesive, the inner surface is flat when the adhesive or the like attached to the inner wall surface is sampled with a spatula, The contents can be taken out smoothly and the work can be done easily, which is economically advantageous.

Further, the raw material cost is low, the manufacturing process is simple, and an expensive mold such as a manufacturing mold is not required, so that the manufacturing cost can be significantly reduced. Furthermore, since the constituent members of the box body itself have a three-layer structure, it is possible to achieve a heat retention effect and a freeze prevention effect.
