Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an upper edge extending between one end and the other end, and a lower edge extending between the both ends, and the one end and the other end are polymerized and connected to each other. The present invention relates to a tubular body forming sheet member in which a tubular body is formed.

[0002]

2. Description of the Related Art The present inventor previously developed a prefabricated device and a tubular body forming sheet member used therein (Japanese Unexamined Patent Application Publication No. 20-29200).
No. 01-63719). A tubular body forming sheet member made of paper such as synthetic paper has an upper edge extending between one end and the other end, and a lower edge extending between both ends, and the connecting means at both ends. Is provided. Then, by utilizing this connecting means, both ends are superposed on each other and connected to each other to form a tubular body. At the lower edge of the sheet member, three slits are formed at intervals in the longitudinal direction of the sheet member and extend in the longitudinal direction.
Each of the slits is formed so as to extend parallel to the lower edge at a position where the height from the lower edge is constant and to face each other at intervals in the longitudinal direction. A band-shaped portion is formed between the three slits and the lower edge corresponding to each of the slits. Each of the belt-shaped portions is configured to be able to be bent inward in the radial direction with both ends in the circumferential direction as fulcrums and curved in a substantially arc shape to project in a state where the tubular body is formed from the sheet member. In the tubular body thus assembled, each of the three band-shaped portions projected inward in the radial direction can be used as the bottom in that state, so that foods such as coffee are enclosed. It can be suitably used as a container for accommodating a bag. Further, the bottom forming body made of a plate-shaped member having an annular peripheral edge is placed on the upper edge of each of the strip-shaped portions protruding inward in the radial direction of the cylindrical body, whereby the bottom-forming body can be detached from the cylindrical body. When the tubular body is mounted on a base and assembled into a container with a bottom, it can be suitably used as a so-called vinyl pot, a flowerpot, a small container, a simple trash can, or the like. A typical example of the tubular body has a circular cross section, and a typical example of the bottom forming body is formed to have a circular peripheral edge.

[0003]

When the tubular body formed of the above-mentioned sheet member is used as a container by combining with the bottom forming body, the bottom forming body is inserted from the upper opening side of the tubular body to the inside thereof. It is inserted, placed on the upper edge of each of the strips that are curved inward in the radial direction and projected, and detachably mounted in the bottom of the tubular body. In order to stably hold the bottom forming body inside the tubular body, it is preferable that the outer peripheral edge of the bottom forming body is fitted to the inner peripheral surface of the tubular body without a gap. Therefore, the diameter of the outer peripheral edge of the bottom forming body is smaller than the diameter of the inner peripheral surface of the cylindrical body so that the outer peripheral edge of the bottom forming body is fitted into the inner peripheral surface of the cylindrical body with a slight press fit. It is formed slightly larger.

When the above-mentioned tubular body forming sheet member is used as a container by combining it with the bottom forming body, the bottom forming body must be manufactured and prepared separately from the tubular body forming sheet member. There is. Therefore, in addition to the mold for molding the tubular body forming sheet member, it is necessary to separately prepare a mold for molding the bottom forming body and mold each separately, resulting in a decrease in production efficiency and manufacturing. High cost. In addition, since the tubular body forming sheet member and the bottom forming body are separated, the member may be lost when the user stores them as containers after separating them from each other or when they are used after the storage. There is. Alternatively, as the number of parts to be stored increases, a larger storage space is required, and storage management and handling of the parts become complicated. Furthermore, it was pointed out that the assembly work of inserting the bottom forming body into the tubular body is relatively troublesome,
There was a desire for further improvement.

In the above-mentioned tubular body forming sheet member, a plurality of strip portions for mounting the bottom forming body (thus, slits for forming the strip portions) are always formed, generally at least three. There must be. In other words, if the number of the band-shaped portions is one, the bottom forming body cannot be placed, so that it does not work as a container. Further, when the number of the band-shaped portions is two, it is unstable, if not impossible, to support the bottom forming body.
When the number of the strip-shaped portions is three, the bottom forming body is stably placed, and the load supporting balance is good, which is a practically preferable form. However, requiring at least three strip-shaped portions increases the number of assembling steps because the number of bending operations inward in the radial direction is relatively large.

The present invention has been made on the basis of the above facts, and an object thereof is to enable molding at the same time with a bottom by a substantially united molding die, and as a result, to improve production efficiency. It is an object of the present invention to provide a novel tubular body-forming sheet member that enables improvement and reduction in manufacturing cost.

Another object of the present invention is to provide a novel tubular body forming sheet member capable of reliably preventing loss of the member during storage after use as a container or during use as a container. Is to provide.

Still another object of the present invention is to provide a novel tubular body which enables the storage space to be minimized and which is remarkably easy to store and the storage management and handling of parts. To provide a forming sheet member.

Still another object of the present invention is to provide a novel tubular body forming sheet member which enables efficient assembling work into a container.

Still another object of the present invention is to provide a novel tubular body which enables stable support of the bottom when assembled in a container by forming only one strip for supporting the bottom. To provide a forming sheet member.

Still another object of the present invention is to provide a novel tubular body forming sheet member which easily enables a substantially flat back surface to be secured relatively wide in an assembled state in a container. It is to be.

Still another object of the present invention is to facilitate stable holding even when mounted on an object to be mounted with a vertical surface or a surface close to vertical as a back in an assembled state in a container. (EN) It is possible to provide a novel tubular body-forming sheet member that makes it possible to relatively easily reduce a projecting space in the front direction from the surface.

Other objects and features of the present invention will become apparent from the following description in detail with reference to the accompanying drawings regarding an embodiment of a tubular body forming sheet member constructed according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGS.
An embodiment of a tubular body forming sheet member configured according to the present invention will be described.

First, referring to FIG. 1, a cylindrical body 1 will be described later.
A tubular body forming sheet member 100 for forming a prefabricated device 200 (see FIGS. 3 to 5) including 10 is made of flat paper. The tubular body forming sheet member 100
In the following description, this is simply referred to as “sheet member 10
It is abbreviated as "0". The sheet member 100 can be made of paper in a broad sense including synthetic paper (any kind of paper may be used if applicable), but more specifically, it is not limited thereto. Although not limited to this, it is preferably composed of paperboard or synthetic paper used in the packaging field. The sheet member 100 in the embodiment is made of synthetic paper. A suitable example of a synthetic paper, which is a sheet member made of plastic as a base material, the surface of which is processed like paper so that printing and writing can be performed, is a registered trademark "Yupo" manufactured and sold by Yupo Corporation. The listed products can be cited as examples [for example, the name "Alpha Yupo", the grade name "QJJ40"
0 "(thickness 0.4 mm)," QJJ500 "(thickness 0.
5mm) or "PII950" (thickness 0.95m
m)]. This synthetic paper "Yupo" has various thicknesses within a range of 0.06 mm to 0.95 mm. As the sheet member 10, 0.1 mm to 3.0 m
Synthetic paper having a thickness of m is practically suitable, but as one example, “Yupo” having a thickness of 0.4 mm to 0.95 mm is suitable. If the thickness of the synthetic paper forming the sheet member 100 is too thin, the rigidity may be too weak to be applied to the prefabricated device 200. On the other hand, if it is excessively thick, there are problems that the rigidity is too strong and it is difficult to handle, it is difficult to apply it to a relatively small assembly type device 200, and the weight and cost increase. If the thickness is in the range of 0.1 mm to 3.0 mm, the above problems can be substantially cleared, and if the thickness is in the range of 0.4 mm to 0.95 mm, the above problems can be more reliably put to practical use. It is something that can be cleared.

The sheet member 100 composed of the synthetic paper as described above has one end 1 as shown in FIG.

It is almost the same as the length of the peripheral edge 18a of 0C except for the first boundary line L1 (either slightly longer, the same, or slightly shorter). Needless to say, the entire circumference of the bottom wall 100C is formed by the first boundary line L1 and the peripheral edge 18a. The corner lower edge 18c is formed substantially on the extension of the first boundary line L1.

And 44), or each of the locking holes 41, can be extremely easily formed by using an appropriate upper die and lower die.
Particularly, the sheet member 100 has a bottom wall 100C that is a bottom.
Since it is integrally provided, it is possible to perform simultaneous molding integrally with the bottom wall 100C by a molding die that is substantially integrated, and as a result, it is possible to improve production efficiency and reduce manufacturing cost. It is a thing.

The sheet member 100 constructed as described above.
When assembling (forming) the container 200, which is an assembly type device, from the flat front wall 100B during molding,
According to the second boundary line L2 (in other words, with the second boundary line L2 as a fulcrum), it is bent to the front side (the front side in FIG. 1), and the surface of the flat rear wall 100A (the front surface in FIG. 1).

According to the third boundary line L3 (in other words, with the third boundary line L3 as a fulcrum), one surface (front surface in FIG. 1) of the other end 14 is one end 12 of the sheet member 100, that is, one end of the rear wall 100A. The part 12 is folded back so that it can overlap. Then, while overlapping one surface of the other end portion 14 of the front wall 100B with the rear surface of the one end portion 12 of the rear wall 100A, each of the locking pieces 22 is inserted into the corresponding slit 20, and as described above, the sheet. By relatively moving the member 100 in the width direction, both ends of the sheet member 100 are polymerized and separably connected (see FIG. 3). This assembles (forms) the tubular body 110 whose opening area is substantially the same from the top to the bottom in the axial direction. The rear wall 100A is substantially flat and the front wall 1
00B is the rear wall 100A on the front surface side of the rear wall 100A.

By bending the bottom wall 100C by 90 ° or more with respect to the surface of the rear wall 100A, the bottom wall 100C is positioned at a temporary position so as to substantially close the inside of the lower edge of the tubular body 110. Then
By forcing (pressing) the strip-shaped portion 35 inward of the front wall 100B in the radial direction, the strip-shaped portion 35 is inverted inward in the radial direction with the bendable lines 35a formed at both ends in the circumferential direction as fulcrums, and has a substantially arc shape. It is curved and projected. The lower edge and the upper edge of the band-shaped portion 35 are positioned on planes substantially parallel to each other in the projected state.
This plane is a plane orthogonal to the axis of the tubular body 110, and is the lower edge 18b of the tubular body 110, that is, the front wall 100B.
It is parallel to the common plane of the lower edge 18b. Although the reason for the above phenomenon is not always clear, the fact that the bendable lines 35a are inclined so that they approach each other from the lower edge 18b toward both ends of the slit 30 results in experiments of the present invention and the like. Have been confirmed by. This configuration enables the cylindrical body 110 and the band-shaped portion 35 to be stably placed on the placement surface, particularly on a flat placement surface, and allows the bottom wall 100C to project radially inward. This enables stable placement on the upper edge of each of the strip-shaped portions 35.

By pushing down the bottom wall 100C in a state where the strip portion 35 is projected inward in the radial direction, the bottom wall 100C is stably placed on the upper end of the strip portion 35 as described above. . At the center in the circumferential direction of the lower edge left on the main body side of the front wall 100B, which is the upper edge of the slit 30 and the corresponding strip-shaped portion 35 is projected, it is substantially the same as the mounting plane of the bottom wall 100C. Since there is a protrusion-shaped portion 34 that protrudes downward from another flat surface, the front wall 100
In the circumferential region of B in which the slit 30 is formed, the protrusion-shaped portion 34 presses the arc-shaped peripheral edge 18a of the bottom wall 100C from the outside to prevent the bottom wall 100C from being displaced radially outward. The protrusion of 100C is sufficiently reliably prevented. As a result, the peripheral edge 18a of the bottom wall 100C
Can be fitted in a predetermined position inside the tubular body 110 without a gap, and can always be stably positioned in a correct posture.
Moreover, the appearance is not damaged. As described above, the tubular body forming sheet member 100 is assembled into the container 200. As described above, since the first boundary line L1 that is the bending fulcrum of the bottom wall 100C is arranged on the extension of the slit 30 or a position slightly above the extension, the bottom wall 100C is It is placed on the upper end of the band-shaped portion 35 in a substantially horizontal state by only a one-touch operation of bending with the first boundary line L1 as a fulcrum. Bottom wall 10
0C is positioned to substantially close the inside of the lower edge of the tubular body 110.

When the sheet member 100 is assembled as described above and used as the container 200 having the bottom wall 100C, the bottom wall 100C is formed as a part of the sheet member 100 and is not separated. Loss is reliably prevented. Furthermore, even after being used as the container 200 having the bottom wall 100C, the bottom wall 100C
Since the sheet is formed integrally with the sheet member 100 and is not separated, the space for storage can be minimized, and the storage is significantly facilitated and the storage management and handling of the parts are facilitated.

Since the bottom wall 100C is connected via the first boundary line L1 which is the lower edge of the rear wall 100A, it is only necessary to form one strip portion 35 on the front wall 100B and the container 2
This enables stable support of the bottom wall 100C when assembled to 00. Since the strip-shaped portion 35 is formed by one piece, elastic deformation work of the strip-shaped portion 35 can be performed at one place.
This makes it possible to more efficiently perform the assembling work into the container 200 as compared with the conventional tubular body forming sheet member in which the elastic deformation work has to be performed at a plurality of places. Further, since the structure is simple, further cost reduction is possible.

When assembling the sheet member 100 into the container 200, the first boundary line L1 and the second boundary line L
Since the second and third boundary lines L3 are bendable lines, they contribute to the ease, speed and accuracy of the assembly work.
In addition, when the sheet member 100 is formed of paper which is relatively easy to crease other than the synthetic paper, any or all of the first to third boundary lines L1 to L3 are assembled without being a foldable line. Sometimes it is possible to bend it directly. In such an embodiment, any or all of the first to third boundary lines L1 to L3 may be set as virtual lines, but if the lines are printed in advance at the places to be bent, it is easy and easy. It is preferable that the bending work can be performed quickly and at an accurate position.

In the seat member 100, the rear wall 100A
Is one end 12a of the sheet member 100 and the second boundary line L
The front wall 100B formed in the region between the second boundary line L2 and the other end 14a while maintaining the rear wall 100A substantially flat. The tubular body 110 is formed by bridging between both ends in the longitudinal direction of the wall 100A (the second boundary line L2 and the one end 12a of the sheet member 100). That is, the sheet member 100 easily allows the substantially flat back surface to be relatively wide in the assembled state of the container 200 due to the presence of the rear wall 100A. as a result,
The assembled container 200 is used as a back surface on a wall surface inside a house, a back surface of a seat back of a seat such as a taxi, a sightseeing bus, or a long-distance train, or a side surface of a desk at school, home, or the like as a back surface. When it is mounted on the rear wall 100A, the rear surface, which is in contact with the surface, that is, the substantially flat rear surface, is secured relatively wide by the rear wall 100A, and thus is stably held. Further, since the space projecting from the vertical surface or the surface close to vertical to the front side is relatively small, there is no obstruction even in a narrow place, and the appearance of the surroundings is not damaged.

As described above, the above-mentioned sheet member 100
In the front wall 100B of the above, at the corner where the other end 14a and the lower edge 18b intersect, the lower edge is a corner lower edge 18c extending from the other end 14a to the other end 14, and the other end 14 is from the lower edge 18b. The corner other end 14b extending to the corner lower edge 18c is formed. Further, the third boundary line L3 has the other end 14 of the corner portion.
b from the other end 14b of the corner portion to the upper edge 16 in the width direction of the sheet member 100.
Is substantially on the extension of the first boundary line L1 (slit 30
Is also an extension of each parallel portion 32). Due to such a configuration, in the state where the container 200 is formed from the sheet member 100, the other end portion 14 superposed on the one end portion 12 of the sheet member 100 from the outer surface is on the rear wall 100A at the superposed portion. The edge 16 and the lower edge defined by the first boundary line L1 do not substantially project upward and downward, respectively, and the front wall 100B.
Lower edge 18b between the other end 14b of the corner and the notch 19
Extends along the peripheral edge 18a of the bottom wall 100C while protruding downward from the peripheral edge 18a of the bottom wall 100C by a substantially constant length, so that a well-balanced appearance of the container 200 is ensured and stable. Placement is also guaranteed.

The container 200 assembled from the above-mentioned sheet member 100 is, as described above, a small container, a flowerpot,
It can be used for various purposes such as simple trash cans, artificial flower pots, pencil stands, spice holders, and deodorant holders. The container 200 assembled from the sheet member 100 according to the present invention has a relatively wide flat back surface due to the rear wall 100A,
Taking advantage of these characteristics, the interior wall surface of a house, the back of the seat back of a seat for private cars, taxis, sightseeing buses, long-distance trains, desks at offices, schools, homes, side surfaces of tables, hospitals and homes, etc. It is preferable to mount the bed with the vertical surface such as the frame of the bed or a surface close to the vertical as the back. Of course, it is also possible to use it by mounting it on a flat mounting surface such as a table or a shelf.

The container 200, which is a prefabricated device, is also lightweight and excellent in water resistance because the sheet member 100 is made of synthetic paper, and the print does not drop even if it gets wet with water. Material deterioration (decrease in strength, change in shape, etc.)
Since it is almost nonexistent, it has excellent durability, and it is placed in a bathroom or outdoors, and there is no problem even if it is bathed in hot water or rained. Further, when it becomes dirty, the dirt can be easily removed and the cleaning property is excellent. Since it is possible to print on the sheet member 100, the design is excellent.

Since the sheet member 100 is made of synthetic paper as described above, the elasticity of the sheet member 100 makes it easy to form the tubular member 110, which is hard to break and has excellent durability. The quality is ensured without deterioration of the material even after long-term use, it can be used many times (semi-permanent use is possible), it is lightweight, and multiple stacks are possible, so transportation Further, in addition to the above advantages, the storage (including display) is easy. Further, in the state where the tubular body 110 is not formed (sheet form), it is possible to stack a plurality of sheets in a significantly small space, so that the transport space and the storage space can be significantly reduced, and the transport and storage can be facilitated. Become. Note that the synthetic paper is easily deformed into the tubular body 110 due to its elasticity, but when the tubular body 110 is released, the synthetic paper also has a restoring property to the original sheet member 100, which is extremely practical. It is convenient (specifically, when performing cleaning, transportation, storage, etc.).

The synthetic paper forming the sheet member 100 can be semi-permanently used as described above, and is extremely economically advantageous for the user. However, if it is discarded, it does not produce harmful substances when burned, and thus can be easily discarded without polluting the environment. That is, after using the container 200, the whole can be discarded as normal paper,
Since it is possible to completely satisfy the requirements for environmental protection, it is possible to fully meet the demands of the times.
