Description

  The present invention relates to a self-contained enclosure member and container that can hold an article inside while being self-supporting when in use, and can be folded when not in use.

  The inventor has invented an enclosure member that can stand up when the upper surface is open when in use and can be folded when not in use. In the self-supporting enclosure member of Patent Document 1, four rectangular surfaces serving as side surfaces are formed by sheet members or mesh members. The ends of the adjacent rectangular surfaces are connected by a bag, and the surrounding member has a rectangular tube shape as a whole. A rigid member can be inserted into the bag body connecting the corner portions of the rectangular surface, and can be self-supporting when sufficient strength is imparted to the corner portions.

  The inventor discloses a technique in which a hard plate-like object such as a plastic plate, a corrugated plastic, a wood plate, or the like is used on the side surface of the self-supporting enclosure member in Patent Document 2. By using a hard plate-like object, it is possible to increase the strength of the enclosure member and to obtain an enclosure member that is not damaged even when a heavier article or sharp article is accommodated. The self-supporting enclosure member of Patent Document 2 uses a single rigid plate-like material as a raw material, and is subjected to processing by mechanical deformation or thermal deformation at a position that becomes a ridgeline (corner portion) at the time of folding. Produces possible enclosure members. A similar self-supporting enclosure member can be manufactured by attaching a hinge etc. to the flat plate for each side, but it is necessary to secure the strength of the attachment location of the hinge etc. Since the cost increases, a self-supporting enclosure member obtained by processing a single plate-like material is more widely used.

  Patent Document 3 discloses a heat-insulating transport device in which a plate-shaped heat insulating member is covered with a jacket and the jackets are sewn so as to be foldable with a hinge cloth. Further, Patent Document 4 discloses a configuration in which a sheet member is sewn to one surface of a component member that constitutes a transport container, and a contact sheet is disposed on the opposite surface. The transport container of Patent Document 4 can be bent at the connecting portion of the constituent members by bending the sheet member.

  The self-supporting enclosure member of Patent Document 1 has a problem that it is difficult to hold a pointed article or a heavy object because the rigidity of the side surface is not so high. Moreover, the self-supporting enclosure member of Patent Document 2 takes time and effort to form a corner portion with respect to a raw material plate-like object. Further, when manufacturing enclosing members having different sizes, it is necessary to change the processing position of the corner portion each time, and there has been a demand for improving the production efficiency in the case of producing a variety of products.

  In order to sew a connecting hinge cloth, the heat insulating transport device of Patent Document 3 needs to cover the entire side plate with an outer cover. In the connection structure of the transport container disclosed in Patent Document 4, the surface of the sheet member that becomes the inner side during folding is determined, and folding in the reverse direction is difficult. In other words, the corner portion of the transport container of Patent Document 4 is formed so as to be folded only in one of the mountain fold and the valley fold, and it is difficult to fold in the opposite direction. In addition, since the connecting member disclosed in Patent Document 4 is folded between the component member and the sheet member without a gap, when applied to the enclosing member, there is a possibility that the user may pinch his / her hand at the folded portion.

  An object of the present invention has been made in view of the above-mentioned problems to be solved by the prior art, and is to provide an enclosure member having a side surface having sufficient rigidity efficiently and inexpensively. is there.

[Embodiment of enclosure member]
Hereinafter, embodiments of the enclosure member of the present invention will be described with reference to the drawings. The enclosure member 1 includes two sets of side surfaces including a first side surface portion 3 that is two rectangular surfaces that face each other when standing independently, and a second side surface portion 4 that is two opposite rectangular surfaces. Hereinafter, the first side surface portion and the second side surface portion are collectively referred to as side surface portions 3 and 4. Further, the surrounding member 1 includes four side surface connection portions 5 that connect the adjacent side surface portions 3 and 4 to each other. FIG. 1 shows a state in which the enclosure member 1 according to the present embodiment is self-supported to create a space in which an article can be stored. The enclosure member 1 in a self-supporting state exhibits a quadrangular prism-like appearance with the upper surface and the lower surface (that is, the bottom surface) removed as a whole. Each of the four side surface connection parts 5 is bent at a substantially right angle to form a side part of the quadrangular column (a contour line connecting the upper and lower ridge angles of the quadrangular column in the vertical direction and its vicinity).

  The four side surface parts 3 and 4 are all formed of a plate-shaped material. As the material for the plate-like material, it is preferable to use a high-strength plate-like material such as a plastic plate, a corrugated plastic, and a wooden board such as a veneer board. Although it is the most common embodiment that all four side portions are formed of the same plate-shaped material, the material is changed between the first side surface portion and the second side surface portion, and particularly strength is required. It is also possible to change the material or the thickness of only one side part.

  In FIG. 2, the elements on larger scale of the connection location of the side parts 3 and 4 and the side surface connection part 5 of the enclosure member 1 are shown. As shown in FIG. 2, the first side surface portion 3 and the second side surface portion 4 adjacent to the first side surface portion 3 are arranged at a predetermined distance. Side connection so that the side 3a of the first side surface 3 and the side 4a of the second side surface 4 are arranged in parallel to each other, and the space between the side 3a and the side 4a is closed. The part 5 is connected to the first side face part 3 and the second side face part 4 by sewing.

  For the side connection portion 5, for example, a polyethylene sheet or a polypropylene (PP) sheet is preferably used. In order to increase the strength, two types of sheets can be bonded together. A mesh-like material can also be used. A high-strength thread such as cotton thread or polyester thread can be used as the suture thread used for stitching the first side surface portion 3 and the second side surface portion 4 and the side surface connection portion 5.

  The suitable connection form of the 1st side surface part 3 and the 2nd side surface part 4, and the side surface connection part 5 is demonstrated. The outer side connection sheet 6 of the side connection part 5 covers the side 3a of the first side part 3 and its peripheral area from the outside, and the inner side connection sheet 7 is the side 3a of the first side part 3 and its peripheral area. And from the inside. The outer side connection sheet 6, the inner side surface connection sheet 7, and the outer side surface connection sheet 6, the first side surface part 3, and the inner side surface connection sheet 7, with the side 3 a of the first side surface part 3 and its peripheral region sandwiched therebetween. The first side surface portion 3 and the side surface connection portion 5 are connected to each other by sewing with a suture thread so as to penetrate all of them. As a result of this stitching, a straight suture line 8 is formed by a suture thread. Furthermore, the outer side surface connecting sheet 6 and the inner side surface connecting sheet 7 in a state of being connected to the first side surface part 3 sandwich the side 4a of the second side surface part 4 and its peripheral region at different parts, and are connected to the outer side surface. The second side surface portion 4 and the side surface connection portion 5 are connected by sewing with a suture so as to penetrate all of the sheet 6, the second side surface portion 4, and the inner side surface connection sheet 7. As a result of this stitching, a straight suture line 9 is formed by the suture thread. In other words, the 1st side surface part 3 and the 2nd side surface part are couple | bonded by each stitching | suture to the separate location of the same side surface connection part 5. FIG. For sewing, a device such as an industrial sewing machine may be applied, but sewing by a manufacturer is also possible.

  Here, the positions where the inner side surface connecting sheet 6 and the outer side surface connecting sheet 7 are sewn in the side surface portions 3 and 4 are torn from small holes opened in the side surface portions 3 and 4 by the stitching needles. It is easily determined on condition that the sides 3a and 4a are not reached. The specific distances from the side edges 3a, 4a to the stitching lines 9, 10 are the physical property values of the material applied to the side faces 3, 4, the plate thickness of the side faces 3, 4, and the stitching. It is specified by performing a stress analysis using the distance from the side 3a or the side 4a of the planned position as a variable.

  When the first side surface portion 3 and the second side surface portion 4 and the side surface connection portion 5 are connected by stitching, between the side side 3a of the first side surface portion 3 and the side side 4a of the second side surface portion 4, A bent region 10 is formed in which the outer side connection sheet 6 and the inner side connection sheet 7 are directly opposed to each other. The folding region 10 is provided with two stitching portions 11 and 12 for stitching the outer surface connection sheet 6 and the inner surface connection sheet 7, and the outer surface connection sheet 6 and the inner surface connection sheet 7 are sewn together. Connected (coupled). The embodiment of the suture site shown in FIG. 2 is a most preferred example. As shown in FIG. 2, stitched portions 11 and 12 are formed by stitching in two straight lines continuously from the upper end portion to the lower end portion of the bent region 10 in parallel with the side edges 3a and 4a. A laminated region 15 in which the outer side connection sheet 6 and the inner side connection sheet 7 having the same width are overlapped is formed in a region sandwiched between the stitched portion 11 and the stitched portion 12. The appearances of the two stitched portions 11 and 12 are two suture lines.

  The enclosure member 1 of the present embodiment is provided with a guide function that stabilizes the shape of the folded region when the stitched portions 11 and 12 are parallel to and parallel to the sides 3a and 4a. Thus, kinking and bending of the bent area can be prevented in advance. Two or more stitching points in the folding area are formed by continuously stitching linearly from the upper end to the lower end of the side connection part, so that the reinforcing effect of the folding area can be increased from the upper end to the lower end. It can be obtained uniformly.

  The width of the laminated region 15 is preferably set to be wider than the plate thickness of the side surface portions 3 and 4. Here, the width of the laminated region 15 is the distance between the stitched portion 11 and the stitched portion 12. The effect in the case where the width of the laminated region 15 is wider than the plate thickness of the side surfaces 3 and 4 will be described with reference to a partially enlarged cross-sectional view of the enclosing member 1 in which the side connection portion 5 is folded in FIG.

  For example, when the surrounding member 1 that is self-supporting in a quadrangular prism shape is crushed so that two adjacent side surface portions 3 and 4 form the same plane, two of the four side surface connection portions 5 are shown in FIG. As shown in FIG. 3, the other two side surface connection portions 5 are in a state in which the folding region 10 is folded back as shown in FIG. 3. The stitched portions 11 and 12 in the bent region 10 are located in the portion with the largest bending amount in the side surface connecting portion 5. At this time, the stitched portions 11 and 12 exert a reinforcing effect. In the present embodiment, the stitched portions 11 and 12 are arranged in a straight line continuously from the upper end portion to the lower end portion of the folding region 10 in parallel with the side edges 3a and 4a. A constant cylindrical shape equivalent to the case where two reinforcing materials are arranged from the bottom to the bottom can be maintained, the shape of the entire bending region is uniformly stabilized, and kinking and bending can be prevented in advance. . As a result, the side surface connection portion 5 of the enclosure member 1 of the present embodiment exhibits sufficient durability even when bending and stretching are repeated.

  In the enclosure member of the present embodiment, the width of the laminated region 15 is made wider than the plate thickness of the side surfaces 3 and 4. Usually, the folded region 10 in a folded state is stable in a shape that generates the least amount of stress, so that the stitched portion 11 is positioned near the extension line of the neutral surface of the side portion 3 and the stitched portion 12 is located on the side portion 4. It will be located near the extension line of the neutral plane. At this time, since the width of the laminated region 15 is formed wider than the plate thickness of the side portions 3 and 4, the laminated region 15 has an arc shape, and when folded, the entire side connection portion 5 functions as a “gusset” and overlaps. A space W can be generated between the inner surface of the side surface portion 3 and the inner surface of the side surface portion 4. With this space W, the user does not have a risk of pinching his / her finger when folding the enclosure member 1, and the user can spread the enclosure member 1 very quickly by placing his / her hand in the space W.

  Other preferable embodiments of the enclosure member 1 of the present embodiment are listed below.

  A stitching point can be further provided between the two stitching points 11 and 12 that define the laminated region 15. By increasing the number of stitches, the strength of the laminated region 15 can be further increased.

  An opening / closing part capable of selecting an open state and a closed state can be provided in one or more of the four side surface connection parts 5 of the enclosure member 1 of the present embodiment. The opening / closing part is preferably constituted by one or both of a notch provided in the side surface connecting part and a closing means using a hook-and-loop fastener and a closing means using a string disposed around the notch. By providing the opening / closing part, it is easy to take in and out the articles accommodated therein. In addition, by configuring the cut portion so that it can be opened from the upper end portion to the lower end portion of the enclosure member 1, it is possible to open the entire cut portion when not in use and fold the entire enclosure member 1 into a vertical shape. It becomes possible to further reduce the size.

  The position where the cut portion is provided is preferably a bent region of the side connection portion. In addition to this, it is preferable to form an element constituting the closing means, such as an eyelet or a string through hole, in a region where the fixing portion 5 and the side surface portions 3 and 4 are overlapped. By arranging and fixing the eyelet and the string through hole so as to penetrate the outer surface connection sheet, the inner surface connection sheet, and the side surface portion, it is possible to ensure the durability around the closing means of the enclosing member.

  A sheet of the same material as that of the side surface connecting portion 5 can be joined by sewing so as to wrap the upper sides of the side surface portions 3 and 4 and the side surface connecting portion 5 and the periphery thereof, thereby forming the upper reinforcing portion 13. Similarly, a plastic sheet made of the same material as that of the side surface connecting portion 5 is joined by sewing so as to wrap the bottom sides of the side surface portions 3 and 4 and the side surface connecting portion 5 and the periphery thereof to form the lower reinforcing portion 14. Can do. By providing the upper side reinforcement part 13 and the lower side reinforcement part 14, the side surface connection part 5 can be further reinforced. Moreover, since the upper side reinforcement part 13 and the lower side reinforcement part 14 can cover all the sharp edges of the upper side and the bottom side of the side parts 3 and 4, the safety when the user handles the enclosure member 1 is ensured. be able to.
