Description

  The present invention relates to a package.

  There are many forms of packaging for packaging various things. Among these, it is convenient to use a rectangular parallelepiped for packaging and transporting and storing a packaged object having a certain size. If it is a rectangular parallelepiped, it is easy to load and store on a pallet or the like, and it is difficult to collapse. In addition, a very large number of packages according to the application are known. Among these, various reports have been made on ordinary rectangular parallelepiped cardboard boxes and packaging containers having a relatively simple structure.

  For example, Patent Document 1 discloses a packaging material that has high strength during transportation and handling, can hold a product other than a rectangular cross section, and can easily separate each product. As shown in FIG. 7, this packing material is a single sheet wound in a substantially rectangular cross section, of which one side is reinforced with a double sheet and the inside has the same cross section as the top surface. A trapezoidal pad (product fixing member) having a bottom surface is provided. The packing material wound in a rectangular cross section can store a plurality of products in the longitudinal direction with pads in between, and the perforation along the cross section of the packing material can be divided while packing each product. There is.

  Patent Document 2 discloses a tray pack for storing an article group (a plurality of individual packs). As shown in FIG. 8, this tray pack accommodates a plurality of individual packs, is open at the top, and has a short longitudinal wall and a transverse wall. And in the corner part, the upright corner support member which attached the angle to the cross section of the same height as an individual pack is provided. The bottom is shaped to correspond to the missing portion of the longitudinal and transverse walls, and is a material-saving design when manufacturing the web of tray packs continuously from a single piece of continuous material.

  Patent Document 3 discloses a cylindrical packing material that can easily cope with different heights and different diameters of different-shaped different bottle containers by folding a sheet-like paper. As shown in FIG. 9, the cylindrical packing material is formed by forming a back plate, a bottom plate, a front plate, and a top plate by winding a sheet of sheet paper into a square tube shape. The ends are pasted together. An eaves-like top plate is further attached to the upper portion of the back plate, and a fold for locking bottles that are objects to be packed is formed on the bottom portion. The top plate is provided with a neck insertion hole for locking the neck of bottles. By adjusting the shape of the neck portion insertion hole and the position of folding the bottom portion, it is possible to pack irregularly shaped bottles with the same packing material.

  Patent Document 4 discloses a packaging box that can reduce the packaging material cost and can observe a part of the stored item from the outside. As shown in FIG. 10, this packaging box is formed by shortening the flaps of the openable and closable portions corresponding to the bottom and top surfaces of a normal cardboard box to provide openings. In this packaging box, zipper parts with perforations are formed at two locations to facilitate unpacking.

Patent Document 5 discloses an information bulletin board set on a multi-pack package in which a plurality of containers such as canned beer are packaged with blank plates. As shown in FIGS. 11 (a) and 11 (b), the multi-pack package with the information bulletin board is folded into the upper portion of the multi-pack package and is locked to the folded portion. An information bulletin board having such a locking portion is detachably attached.

  As described above, various packaging bodies have been reported, and in particular, many paper packaging bodies such as corrugated paper are provided with an exterior according to the application while utilizing the strength of the contents. In these packaging bodies, although handling properties such as transportation and storage as the packaging bodies are sufficiently taken into consideration, there are few that consider the convenience in taking in and out the contents, particularly in taking out. Furthermore, there are hardly any items that are considered to be convenient for taking out the contents on the premise that the package is reused.

  For example, in the case of a normal rectangular parallelepiped corrugated cardboard box, if the contents are tightly fit in the cardboard box, the rigidity of the contents will reinforce the strength of the cardboard box, making it possible to transport each cardboard box and handle multiple layers. Is convenient, but it is often time-consuming to store and take out the rectangular parallelepiped box and the product as the contents in the cardboard box. In particular, it is often difficult to take out a box or a plate-like content having a cross section that fits in the opening surface of the cardboard box. For this reason, the cardboard box is often destroyed so that it cannot be reused. In many cases, the cardboard box is assumed to be destroyed and not reused.

  As mentioned above, when packaging items such as boxes and plates that are the contents are packed in a package such as a cardboard box and transported or stored, the strength of the cardboard box is not required so much. The ability to easily store and retrieve items is an important issue. Such a problem also applies to containers other than ordinary cardboard boxes. In particular, when the box is not a rectangular parallelepiped box such as a normal cardboard box, there are few reusable ones, which is also a problem from the viewpoint of resource saving.

  In view of the above problems, an object of the present invention is to provide a package that is easy to handle such as transportation and storage, can be packaged and unpacked easily, and is suitable for reuse.

In order to solve the above problems, the present inventors have completed the following invention.
The present invention is a cylindrical package having a quadrangular cross section and open at both ends, and has a folded portion that is folded so that the corners in the vicinity of the opening are convex toward the facing corner direction. It is the package characterized by the above-mentioned.

  A preferable aspect of the present invention is the packaging body having the folded portion at all corners near the opening at both ends.

  In a preferred aspect of the present invention, an auxiliary stopper in which a part of the side surface is folded to the opening side is provided between the adjacent folding portions on the side surface including the adjacent folding portions on the same opening side. It is the said package.

  In a preferred aspect of the present invention, the length of the folding margin between the adjacent folding portions sandwiching the auxiliary stopper is 1/3 or less of the length of the side surface.

  In a preferred aspect of the present invention, the length of one folding allowance of the folded portion is ½ or more of the length of the side surface.

  A preferable aspect of the present invention is the package body including a spacer that is sandwiched between the adjacent folded portion on the same opening side and the packaged object to be packaged.

  The present invention is a cylindrical packaging body having a quadrangular cross section and open at both ends, in which a cut is provided at a corner near the opening substantially parallel to the opening, and the corner is opposed to the opposite corner. The package is characterized in that it can be folded so as to form a folded portion.

  In a preferred aspect of the present invention, the package is characterized in that a fold for folding toward the opening is provided in the folded portion of the corner portion.

  A preferred embodiment of the present invention is the package body made of corrugated paper.

  According to the present invention, it is possible to provide a package that is easy to handle such as transportation and storage, can be packaged and unpacked easily, and is suitable for reuse.

  The best mode for carrying out the present invention will be described with reference to the drawings as necessary. Note that it is easy for a person skilled in the art to make other embodiments by changing or correcting the present invention within the scope of the claims, and these changes and modifications are included in the scope of the claims. The following description is an example of a preferred embodiment of the present invention, and does not limit the scope of the claims.

(Embodiment 1)
The packaging body of Embodiment 1 of the present invention has a cylindrical shape with a substantially square cross section and is open at both ends, and is folded so that the corners in the vicinity of the opening are convex toward the opposing corners. A folded portion. The folded portion has only two sides of a substantially rectangular cross section when viewed from the opening side. Normally, all the eight corners in the vicinity of the openings at both ends have the folded portions, but in some cases, the folded portions may be present only at some corners. It can be selected according to the purpose and purpose of the package. In addition, although the arrangement of the respective folding parts (distance from the opening of the locking position of the folding part described later) can be adjusted, the folding parts arranged in the same opening usually have a packaging for locking the package. It is preferable that the latching | locking part which is an edge part by the side of a body inside has aligned on the cross section parallel to the opening part of a cylindrical packaging body.

  A perspective view of the package of the present invention is shown in FIG. Moreover, the front view and side view of this package are shown in FIGS. 1 to 3, the package 1 has an appearance similar to that of a normal rectangular parallelepiped cardboard box or the like. However, the two opposite faces of the hexahedron are open. And this opening part is often used as a side surface. Contents to be packaged are taken in and out from the opening. In the example shown in FIGS. 1 and 2, as shown in FIG. 2, rectangular box-shaped articles 4a and 4b having a size obtained by folding the inner cross section of the package 1 up and down are stacked and packaged. ing. Explaining the four corners near one opening (front side in FIG. 2), the packaging body 1 is cut in the cross-sectional direction (direction parallel to the opening) at the portion corresponding to the folded portion on the side. The side surface of the cut portion is folded 90 degrees inward, and the folded portion in the vicinity of the ridge of the package becomes convex toward the opposite corner, forming the folded portions 3a, 3b, 3c, 3d. Has been. When viewed from the front view of FIG. 2, the folded portion and the side are substantially rectangular. As can be seen from FIGS. 1 and 3, four folds 3e, 3f and the like are formed in the same manner at the four corners of the other opening.

  This packaging body may use any material as the packaging body material 2, but a sheet-like material having appropriate elasticity, rigidity, and strength as a box-shaped packaging body material that is usually used is preferable. Specific examples of the packaging material 2 include corrugated paper, cardboard, plastic sheets, and metal plates. Among these, corrugated paper and cardboard are excellent materials in terms of balance of physical properties such as elasticity, rigidity and strength, flexibility, processability, material cost, disposal as waste, and ease of recycling. .

  The taking in and out of the packaged article into and from the package 1 will be described. The form before use of this package is a package in a state where the folded portions 3a, 3b, 3c, 3d, 3e, 3f and the like formed at the corners are not folded. However, the packaging body before use has a portion corresponding to the folding portions 3a, 3b, 3c, 3d, 3e, 3f, etc., and the cut portion on the side surface of the packaging body has a cut, and the portion corresponding to the folding portion When the ridge portion is pressed toward the opposite corner, a part of the side surface is bent toward the opening to form a folded portion. In addition, if a crease such as a perforation is formed in advance in a portion that is bent toward the opening side of this side surface, not only folding is easy, but also accurate folding is easy.

  When storing an article to be packaged in the package before use, first, the ridge portion of the corner portion of one opening portion is pressed toward the opposite corner portion to form a folded portion. In this case, as shown in FIG. 1, if four folds are assumed in one opening, it is preferable to form the folds at all four locations. Then, the articles to be packaged 4a and 4b are inserted into the package 1 from the opening on the side where the folding part is not formed. When the articles to be packaged 4a and 4b have been inserted into the package 1, the corners that are supposed to be folded in the openings on the side where the articles to be packaged 4a and 4b are inserted are pressed to form the folded parts. To do. It is preferable that perforations and the like are put in the folds in advance so that the folds are easy to fold.

  If the length of the package is known in advance, adjust the position in the side length direction of the folded part of the package, especially the position of the cutting part, according to the length of the package. The packaged item can be stored exactly inside the package. If it does in this way, the collapse of the load in the transportation and handling of a package, the damage of the contents, etc. can be prevented.

  When taking out the package from the package, make sure that the folding part of at least one of the openings is in the state before folding, that is, the opening is in the same plane as the rectangular cylindrical side. What is necessary is just to take out the package from here. At this time, if the cylindrical portion of the package body is tilted obliquely with the opening portion from the horizontal state serving as the take-out port on the lower side, the package object will naturally slide out of the package body. At this time, since the air can freely enter into the package from the opening on the opposite side even if the package is exactly within the cylindrical portion of the package, the bottom and the package are Therefore, the package can be smoothly slid out. Further, depending on the surface properties of the package, it may be difficult to slide out naturally, but the package can be easily removed by pressing it from the opening on the opposite side of the outlet. The operation of taking out the package can be adjusted by the lower limit of the pressing force or the inclination.

  The package from which the package is taken out can be reused by immediately storing a new package with the folded portion formed in one opening. Alternatively, with the folded portion formed, or returned to the tubular body before folding all the folded portion, the two ridges of the tubular body are pressed and crushed, and folded into two endless sheets. It may be stored in the form. If it is set as such a form, this package will be very convenient to store and handle.

  This package can be manufactured using all the parts of the rectangular sheet and there is no part to cut and remove. In other words, the packaging body only needs to have a rectangular sheet for the glue amount that joins the four side surfaces of the rectangular cylindrical body and the end portions of the side surfaces as the packaging material. When this package is manufactured in large quantities, it can be manufactured by cutting a long sheet without waste.

  As a manufacturing method, it is preferable to arrange so that four side surfaces are sequentially formed from a sheet of packaging material, and to provide an adhesive margin at the end of the last side surface. A crease such as a perforation is formed at the boundary between each side surface and the adhesive margin, and a quadrangular cylindrical body is formed by joining the first side end portion and the adhesive margin. Furthermore, what is necessary is just to form the notch | incision and the crease for folding parts in the position corresponding to a folding part for forming a folding part in the corner | angular part of an opening part. The cuts and the perforation for the folding portion may be performed when the fold is made at the boundary of the side surface. In this way, the sheet material can be used without waste, and the manufacturing process is very simple and short. In addition, there are few restrictions on the selection of the sheet material.

(Embodiment 2)
The package to be stored in the package of the first embodiment described above is the package when the package package is stored in the package as seen from the opening side, such as the rectangular casing shown in FIG. A shape that fits in the cross section of the body without gaps, and a shape that allows each part of the package to be easily locked to the folding part so that it does not come out of the opening by being locked to the folding part of the packaging body. Those are preferred. In particular, the portion facing the opening is preferably the above-described shape. In the example shown in FIG. 1 and FIG. 2, the two packaged articles 4a and 4b are in a form that fits exactly in the cross section of the opening, and the packaged articles 4a are respectively wrapped by the left and right folded parts 3a and 3b. The object 4b is locked by the left and right folding parts 3c and 3d.

  However, the packaged item is relatively small. For example, as shown in FIG. 4A, any of the folded portions 3a, 3b, 3c, 3d as in the central packaged item 4c facing the opening. In some cases, there is no portion to be locked. In such a case, in the package in the state shown in FIG. 2, the package 4c may jump out of the opening when the package is tilted during handling such as transportation of the package or palletizing. .

  As shown in the front view of FIG. 4 (a), the packaging body of Embodiment 2 includes a part of the side surface between the adjacent folding portions on the side surface including the adjacent folding portions on the same opening side. Auxiliary stoppers 5a and 5b folded inward are provided. As shown in the side view of FIG. 4 (b), the auxiliary stoppers 5a and 5b are located in the middle of adjacent folding portions (for example, the folding portions 3b and 3c) on the side surfaces, and are provided with folds for forming the auxiliary stoppers. Then, a cut is made in a substantially semicircular shape from the fold toward the opposite side of the opening, and the fold is folded inside the package to form a tongue-like shape (for example, auxiliary stopper 5b). As shown in FIG. 4A, the auxiliary stoppers 5a and 5b can lock an object to be packaged 4c located at the center of the opening.

  In the example shown in FIGS. 4A and 4B, two auxiliary stoppers are provided in each opening, but it is not necessary to be particular about the number of auxiliary stoppers. If necessary, it may be provided also in the vertical direction of the opening in FIG. 4A, or a number of auxiliary stoppers may be provided on one side. Further, if only one package is required as a whole, only one auxiliary stopper may be provided.

  The shape of the auxiliary stopper may be any shape other than a semicircular shape, such as a square shape, a triangular shape, a semi-elliptical shape, and the like. What is necessary is just to adjust the magnitude | size of an auxiliary stopper by the magnitude | size of the to-be-packaged object latched, the importance of weight latching, etc. In addition, in order to maintain the rigidity of an auxiliary stopper, it is suitable for the packaging material in the packaging body of this embodiment to use a metal sheet, a plastic sheet, and corrugated paper with comparatively high rigidity and strength.

  When the packaging bodies of Embodiments 1 and 2 are made of corrugated paper or cardboard, it is preferable that the size of the folding margins of the folding portions 3a, 3b, 3c, 3d, 3e, 3f, etc. is not so large. The folding allowance is the length in the package cross-sectional direction where the side surface of the cylindrical package is folded at the folded portion, and the folding allowance of each folded portion is formed by the folded portion. The length is preferably 1/3 or less of the entire length of the original side surface. For example, referring to the front view of FIG. 2, the folding allowance of the folding portion 3a, that is, the vertical length of the folding portion 3a in FIG. Say the following. The same applies to the folding margin in the left-right direction. In the first embodiment, an upper limit may be provided for the size of the folding margin due to the strength of the folding portion. In the second embodiment, however, the folding portion is expected to share the locking action with the auxiliary stopper. The folding allowance is reduced.

(Embodiment 3)
As shown in the front view of FIG. 5, the packaging body according to the third embodiment has a configuration in which the length of a part of the folding portion is set to ½ or more of the side length. In this case, instead of providing the auxiliary stopper shown in the second embodiment, the folding margin of a part of the folding portion (for example, the folding margin of the left side surface of the folding portion 3a) is lengthened, and the length is more than half of the side surface. It is said. If it does in this way, the to-be-packaged goods in a center part will be latched by this folding part at least in this side surface.

(Embodiment 4)
The packaging body of Embodiment 4 is provided with spacers 5a and 5b as shown in the front view of FIG. The spacers 5a and 5b are respectively disposed between the folded portions 3a and 3b and the folded portions 3c and 3d and the article to be packaged. The spacers 5a and 5b have a function of locking an object to be packaged that is near the center of the opening and is not locked to any of the folded portions 3a, 3b, 3c, and 3d. In the example shown in FIG. 6, two spacers are arranged on the left and right side surfaces and are not arranged on the upper and lower side surfaces. However, the spacers may be arranged on the upper and lower sides instead of the left and right sides or in addition to the left and right sides. The width of the spacer may be adjusted according to the purpose, and at the maximum, one spacer may be arranged so as to cover the entire opening. The spacer may be made of a material so that the inside of a transparent plate, a lattice plate, a mesh plate, or the like can be observed. Usually, the same material as the package body, such as corrugated paper or cardboard, is often used.

  The package of the present invention is a package of one or a plurality of various articles that have been packaged in a commonly used rectangular parallelepiped cardboard box, in particular, a relatively large rectangular parallelepiped product or an article contained in a rectangular parallelepiped container. It is convenient as a means for transportation and storage. Since the packaging body of the present invention has an opening, the inside situation can be observed without unpacking, and since it is a rectangular parallelepiped, the pallet is not particularly bound like a conventional cardboard box. It can also be transported and stored in multiple layers. In addition, handling, especially removal, of stored articles is easy, and the contents can be taken out without damaging the package. Further, after taking out the article, the package itself can be made into a flat square plate with almost one touch, and the package can be easily stored, transported and handled. Furthermore, since the article can be easily taken out, the package is not damaged at the time of taking out, and the package can be easily reused, which is preferable in terms of resource saving. Also in the manufacturing process of this package, the sheet | seat used as a raw material is hardly wasted, a manufacturing process is short, and it can manufacture at a very low cost.
