Description

[Detailed description of the invention] This invention relates to a paper fluid container with a waterproof inner surface, which can be constantly conveyed in a flat state, and can be quickly assembled as a fluid container by simply pressing the side edges when injecting fluid. Containers that can be used.

This fluid container can be widely used in the food industry for beverage concentrates, vinegar, coffee powder, etc., and in the chemical industry for undiluted cleaning solutions, fertilizers, paints, etc.

Conventional containers of this type have been previously formed into a box shape and carried to a fluid filling position, and after the fluid has been injected, the lid portion has been sealed.

However, in the case of fluid filling using an automatic conveyor system, in the case of non-automated fluid filling, it is necessary to carry the box-shaped container as it is, and although it is lightweight, it is bulky and extremely difficult to transport. It was inconvenient.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional methods.The container itself can always be carried in a folded flat form, making it extremely easy to transport, as well as being easy to assemble into the container, and the inner surface is waterproof. The container can be made from a simple paper sheet by simply fusing or fixing the necessary edges, and can be manufactured at low cost.

That is, the gist of the present invention is that the Japanese paper has a waterproof inner surface, and includes side wall portions 1, 2, 3, and 4 of the same width and an adhesive piece 5 connected by vertical fold lines, and each of the side wall portions 1, 2, 3, and 4 top wall portions 1a, 2a, 3a, 4a bendably connected to the top, and two side wall portions 1, 2.
and bottom parts 6 and 7 of an isosceles triangle whose lower edges 3 and 4 are refractable bases, and the bottom parts 6 and 7 form a sheet with a perpendicular b to the base and a perpendicular b
Perpendicular lines c and d to sides a of the bottom parts 6 and 7 with the hanging point as the base point are bent lines, and the bottom is bent at the vertical fold line between the side wall parts 2 and 3, and the adhesive piece 5 is bonded to the corresponding position and overlapped. The present invention relates to a fluid container in which the edges of portions 6 and 7 are adhered from the outer surface with adhesive tape or the like, and can be opened by actively pressing between side wall portions 1 and 2 and between 3 and 4.

A specific example of the present invention will be explained with reference to the drawings.

In the developed view of FIG. 2, there are side wall portions 1, 2, 3, 4 and an adhesive piece 5 of the same width, and the adhesive piece 5 is bent at the fold line between each side wall portion to attach the adhesive piece 5 to the side wall portion 4.
Glue to the edge of. During transportation, between side wall parts 1 and 2,
The fold line between the side wall portions 3 and 4 is not bent and is carried as a flat plate.

In the present invention, the bottom portions 6 and 7 have a special shape, that is, the bottom portion 6 is a right-angled isosceles triangle whose base is the lower edge of the side wall portions 1 and 2, and the side wall portions 3 and 4 have a special shape.
Bottom part 7 of a right-angled isosceles triangle whose base is the lower edge of
is formed into a bulge on the container sheet, bent at the fold line between the side wall parts 2 and 3, and the bottom parts 6 and 7 are overlapped, and the sides a of the overlapped bottom parts 6 and 7 are aligned from the outside. After sealing the fluid with adhesive or adhesive tape 8, etc., they are connected. With this configuration, the bottom of the container is sealed and there is no leakage of fluid when the container is used as a container.

Although the bottom parts 6 and 7 have the above-mentioned shape, since the material is made of paper, they are placed on the perpendicular line b of the triangle formed by the bottom parts 6 and 7 and on the perpendicular line b so that the bottom part can be folded in half smoothly when bent. Broken lines are respectively carved on perpendicular lines c and d to side a starting from the hanging point.

The container according to the present invention is made into a flat shape from the sheet shown in FIG. 2 using an adhesive piece 5, an adhesive, an adhesive tape 8, etc. as shown in FIG. When forming an open container, when the edges of side wall portions 2 and 3 and the edge between side wall portions 1 and 4 are pressed in the direction of the arrow in Fig. 1, side wall portions 1, 2, 3, and 4 open into a prismatic shape. At the same time, when some pressure is applied to the intersection of the perpendicular lines c and d with the side a, the bottom parts 6 and 7 will be bent inward and the perpendicular line d will be bent, as shown in Figure 3. Then, the side a of the triangular bottom portions 6 and 7, which had been bent, becomes flat and square. Next, when the bulging part formed by the perpendicular line b is folded over the top surface of the square bottom part, it almost matches the dimensions of the square bottom part, so it is glued and integrated with the square bottom part with adhesive or adhesive tape 9 as appropriate. , a flat expected bottom portion is completed.

The top wall portion of the container is shown as an example of a portion corresponding to the sealing of the top wall of a milk carton or the like.

That is, the top wall portions 1a, 2a, 3a, 4a are folded inward at the fold line e to form the lid adhesive portions 1b, 2b, 3b, 4b.
glue together. In the present invention, the portion corresponding to the top wall is not limited to the illustrated shape, but may have any other arbitrary shape.

In this invention, the bottom parts 6 and 7 of a right-angled isosceles triangle with special fold lines are formed on a paper sheet such as cardboard with a waterproof inner surface, and the flat container is made by simply gluing the necessary parts. Not only is it extremely inexpensive and simple, but since it is a flat body, it does not take up much space to transport.Moreover, the bottom of the container can be formed by pressing in the direction of the arrow shown in Figure 1 and placing your hand a little on the part corresponding to the bottom. After that, a usable container is completed by simply attaching it with adhesive tape, etc., so anyone can easily form a container from a flat object in a short time. It can also be used as an inner bag by covering the periphery of the flat body shown in Figure 1 with cardboard.

In the specific example of the present invention, the bottom part of the container is shaped like a right isosceles triangle, but the top wall part can also have the same shape as the bottom part.

However, if the top wall portion is shaped like a right-angled isosceles triangle, it is necessary to provide a fluid inlet and a plug at appropriate locations.
