Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a cylindrical container with a lid that is flat when not in use and becomes three-dimensional with a simple operation when in use.

(Prior Art) As a cylindrical container with a lid that forms a flat shape when not in use and becomes three-dimensional when in use, for example, the invention described in Japanese Utility Model Publication No. 55-5447 and Japanese Utility Model Publication No. 55-5448 has been proposed. There is.

The former has edge plates that are folded back and overlapped on the inner surface of the body plate connected to the upper and lower ends of the body plate, and a bottom plate and a lid plate are connected to a part of the upper and lower edge plates, and the edges are connected to the body plate. The outer peripheral edges of the bottom plate and the lid plate are supported by the folded edges of the edge plate.

The latter has a bottom plate that can be bent at the center connected to one side edge of the lower end of the body, which has an oval cross-sectional shape, and the tip of this bottom plate is fixed to the other side edge of the lower end of the body. A lid plate that closes the upper end opening of the body is connected to one side edge of the upper end of the body, and a thick fitting body that can be fitted into the opening is attached to the inner surface of the lid plate.

(Problem to be solved by the invention) However, in the former case, at least one of the lid plate and the bottom plate is made to stand up after the contents are placed in the container, and the edge plate is removed from the outside. Since the container is folded and fixed, it takes time to assemble it, and it is also troublesome to have to raise the edge plate each time to take out the contents.

In the latter case, a fold line is formed on the bottom plate, and the bottom plate is only fixed to the body plate at the continuous portion and the fixed portion, so the bottom plate lacks strength. In addition, this idea has the problem that it is difficult to apply to cylindrical containers because the bottom plate and the lid plate are connected directly to the upper and lower ends of the body plate, and furthermore, the lid plate is difficult to fit. be.

In view of these points, the present invention provides a cylindrical container that can be assembled with one touch, has excellent strength in the assembled state, has a lid that can be opened and closed easily, and is also applicable to cylindrical containers. The purpose is to

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has a body plate that forms a body by fixing both ends to each other, and a body plate that closes the open bottom surface of the body. A cylindrical container comprising a bottom plate that closes the open top surface of the body, and a lid plate that closes the open upper surface of the body, the body plate having a folded piece continuous to the lower end that is folded back and overlapped with the inner surface of the body plate; The bottom plate consists of a bottom plate main body and a mounting piece that bendably attaches the bottom plate main body, and the cover plate consists of a cover plate main body and a mounting piece that bendably attaches the cover plate main body. Attach the mounting piece of the bottom plate mentioned above to the lower end of the folded body plate in an appropriate position so that the bottom plate body is positioned upward, and attach the mounting piece of the cover plate mentioned above to the upper end of the body plate so that the body plate body is positioned upward. In addition, an auxiliary body plate having an outer circumference approximately equal to the inner circumference of the body is inserted into the body, and the lower peripheral edge of the bottom plate is supported by the upper end of the folded piece, while the lower peripheral edge of the cover plate is supported by the upper end of the folded piece. It is characterized in that the upper end of the auxiliary body plate supports the upper end of the auxiliary body plate.

(Function) Before assembly, the cylindrical container of the present invention is housed in the body so that the bottom plate is parallel to the surface of the body plate, and the lid plate is parallel to the surface of the body plate. Since it protrudes from the upper end of the body, by flattening the body and the auxiliary body at the required positions, the entire body is flattened.

During assembly, when the top surface of the bottom plate body is pushed down by the bottom of the contents, the bottom plate body is supported by the upper end of the folded piece, and the body portion expands along the outer periphery of the bottom plate body.

After storing the contents, when the lid plate main body is placed over the body opening, the lid plate main body is supported by the upper end of the auxiliary trunk plate and held in a predetermined position.

(Example) Hereinafter, the present invention will be explained in detail based on an illustrated example.

FIG. 1 is an external perspective view of a cylindrical container according to an embodiment of the present invention, and FIGS. 2A to 2E are plan views of each component constituting the cylindrical container.

This body plate 1 is made of thick paper such as corrugated cardboard, and has folded pieces 3 and 4 of a required width arranged at the upper and lower ends of the body plate so that they can be folded back and overlapped on the inner surface of the body plate, except for the overlapping portions 1a at both ends. ing.

Reference numeral 5 denotes a lid plate that closes the open upper surface of the body portion 2. As shown in FIG. 2B, the lid plate 5 includes a circular lid plate main body 6 and a mounting piece 8 protruding from its outer periphery.
The cover plate main body 6 has a diameter that is approximately equal to the inner circumference of the upper end of the body portion where the upper folded piece 3 is folded back. The mounting piece 8 is formed to have a width approximately equal to the width of the overlapping portion 1a of the body plate 1 described above. Reference numeral 7 denotes a knob protruding from a position facing the attachment piece 8 on the outer periphery of the lid plate main body.

Reference numeral 9 denotes a bottom plate that closes the open lower surface of the body portion 2. As shown in FIG. 2C, the bottom plate 9 consists of a circular bottom plate main body 10 and a mounting piece 11 protruding from its outer periphery. The bottom plate main body 10 has a diameter approximately equal to the inner circumference of the body portion 2. The mounting piece 11 is formed to have a width approximately equal to the width of the overlapping portion 1a of the body plate 1, similar to that of the lid plate 5 described above.

Reference numeral 12 denotes an auxiliary body plate having a width approximately equal to the inner circumference of the body, and is inserted into the body so as to be wrapped around the inner circumference of the body. This auxiliary body plate 12 is
When the bottom plate 9 is inserted into the assembled body as will be described later, the upper end becomes the upper folded piece 3.
The height is high enough to cover the folded inner surface of the

Reference numeral 13 denotes a handle having bulged heads 14 at both ends, and is attached to the upper outer circumference of the body 2.

The assembly of this container will be explained with reference to FIGS. 3 to 5. First, the upper and lower folded pieces 3 and 4 of the body plate 1 are folded back, and the overlapping parts on both sides of the body plate are fixed with screws 15 at intervals in the height direction.
At this time, the mounting piece 1 of the bottom plate 9 is attached to the lower end of the inner surface of the overlapping part.

Further, the bulging head 14 of the handle 13 is fixed to the upper outer surface of the body 2 with screws.

In this state, the bottom plate 9 is stored in the body so as to be parallel to the plate surface of the body plate 1, and the cover plate 5 is parallel to the plate surface of the body 2 and protrudes from the upper end of the body. , the whole is in a flat state. Therefore, it is not bulky when not in use, making it easy to store and transport.

In use, the bottom plate main body 10 is pushed down by the bottom of the stored object, etc.
0 is bent from the attachment piece 11 and supported by the upper end of the folded piece 4. In addition, the lid plate 5
The auxiliary body plate 12 is inserted into the body, the contents are stored in the body, and then the body opening is covered. This cover plate 5 is stably fixed by having the lower peripheral edge of the cover plate main body 6 supported by the upper end of the auxiliary body plate 12 (see the sectional view in FIG. 7).

In this cylindrical container, since the bulging head 14 of the handle 13 projects upward from the upper surface of the body, a large number of cylindrical containers can be stacked one above the other as shown in FIG.

Although the above-mentioned embodiments have been described with respect to cylindrical containers, the present invention can be similarly applied to polygonal cylindrical containers.

(Effects) As described above, according to the present invention, when not in use, the bottom plate and the lid plate are assembled parallel to the plate surface of the body plate, so they are not restricted by the shape of the body part. By flattening the body plate and the auxiliary body plate, the entire body can be flattened, and when in use, the bottom plate body stands up from the plate surface of the body plate and is supported by the upper end of the folded piece, while the cover plate body is placed on the body plate. By standing up from the plate surface and supporting it at the upper end of the auxiliary body plate, it can be easily made three-dimensional with one touch.

Further, since the auxiliary trunk plate is inserted so as to be wrapped around the inner periphery of the trunk, the overall strength can be significantly improved.

Furthermore, the lid plate has a mounting piece attached to the upper end of the body plate, and is bent from this mounting piece to cover the lid plate body on the upper surface of the body, so that opening and closing operations can be easily performed. .
