Description

The present invention relates to a sleeve-shaped container formed in a tubular shape and holding an article inside, and a sleeve-shaped container having a function of holding the stored article so as not to fall off.

Conventionally, a sleeve-shaped packaging container that surrounds an article from four sides and has the remaining two sides open is known. Such a sleeve-shaped container is provided with a structure for holding the stored object in the container so that the stored object does not fall off from the opened surface. For example, Patent Document 1 discloses a sleeve-shaped carton for accommodating a plurality of cylindrical cans, and this carton is provided with a notch for holding the heel portion of the can. Since the can is generally made of metal and has high rigidity and is not easily deformed, it is well held by such a notch, and the heel part exposed from the notch is less likely to be seriously damaged. , It is presumed to be effective.

Further, Patent Document 2 discloses a wrap-around carton in which a paperboard sheet is assembled to store bottles in parallel, and a notch or a notch is provided at a portion corresponding to the bottom and top of the bottle to provide a corner portion of the bottle. It is easy to hold. Since the bottle is generally made of a material having high shape retention such as glass and PET, it is presumed that the bottle can be held well as well.

Further, Patent Document 3 discloses a carton holder for storing a plurality of so-called Goebel top type cartons, and states that the carton is locked by fitting a gassho sticking piece on the roof of the carton into a slit. It is suitable for holding a carton of a specific shape called a Goebel top type. As described above, when the stored object is stored in the sleeve-shaped container, it is widely practiced to provide a notch or a slit in a part thereof and to fit a part of the stored object to improve the holding property. It was.

However, on the other hand, in order to provide a notch or slit in the sleeve-shaped container, a special die-cutting blade that matches the shape of the notch or slit is required, and a separate die-cutting process is required. It was costly.

Further, even if a holding portion such as a notch is provided, if the stored object is a tray-shaped container made of plastic having relatively low rigidity, the stored object is easily deformed from the holding portion during transportation or the like. There is a risk of problems such as slipping out, the shape of the part protruding from the holding part being unstable and unsightly, and the part such as the corner of the container protruding from the holding part being easily damaged. In particular, when a plurality of these containers are stored in a stacked state, it is easier to pull out, so improvement has been desired.

Therefore, the present invention can reduce the manufacturing process and cost, and even when one or more plastic resin containers such as trays, which are relatively easily deformed as the objects to be stored, are stored, they fall out of the sleeve. An object of the present invention is to provide a difficult sleeve-shaped container.

In order to solve the above problems, the present invention
A square tubular sleeve-shaped container formed by bending paperboard, with the bottom surface, left side surface, top surface, and right side connected in this order, and the front and rear surfaces open.
The sides of the top surface that are in contact with the left side surface and the right side surface have an entry portion that is inserted in the left-right direction.
The sleeve-shaped container is characterized in that the left side surface and the right side surface are provided with fold ruled lines that are convex inward from the apex of the entry of the entry portion toward the bottom surface.

That is, in a sleeve-shaped container that is square-cylindrical and has an open front and back, the top surface portion has an insertion portion, and inwardly convex fold ruled lines formed on the left and right side surface portions from the apex of the insertion portion toward the bottom surface. In addition, since the side portion of the stored object is pressed, a sleeve-shaped container in which the stored object does not easily come off can be configured.

In the sleeve-shaped container,
The left side surface and the right side surface have at least one outwardly convex fold ruled line extending in the front-rear direction, and the inwardly convex fold ruled line reaches the most top side of the outwardly convex fold ruled line. It may be the mode in which. By having a convex fold ruled line on the outside, the upper part of the left and right side surfaces can easily fall inward, and the stored object can be effectively pressed.

In the sleeve-shaped container,
The distance between the apex of the entry on the left side surface side and the apex of the entry on the right side surface side of the insertion portion may be the width for sandwiching the object to be stored. The items to be stored can be pressed more strongly.

In the sleeve-shaped container,
The insertion portion may be provided at two locations on the side in contact with the left side surface and / or the side in contact with the right side surface. It is possible to hold down the items to be stored more stably.

In the sleeve-shaped container,
A notch may be provided on a side where the left side surface and the right side surface are in contact with the bottom surface.

In the sleeve-shaped container,
The paperboard may have a basis weight of 100 to 500 g / m ² , more preferably 200 to 400 g / m ² .

According to the present invention, it is not necessary to prepare a notch or a slit for holding an object to be stored by preparing a mold blade or the like, and it can be formed by simply folding a paperboard with a fold ruled line, which is easy to create. It is possible to obtain a sleeve-shaped container in which the stored object does not easily come off.

FIG. 3 is a plan view of a blank sheet forming an embodiment of the sleeve-shaped container of the present invention. The explanatory view of the state which holds the stored object in one Embodiment of the sleeve-shaped container of this invention. FIG. 6 is a schematic external view of a second embodiment of the sleeve-shaped container of the present invention. Top view of an example of a blank sheet in which two vertices are provided in the insertion portion. An explanatory view of a state in which an object to be stored is held by a sleeve-shaped container provided with two vertices in the insertion portion. FIG. 6 is a schematic external view of a third embodiment of the sleeve-shaped container of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments described below. Further, in the following, the same reference numerals may be given to equivalent members and the like, and the description thereof may be omitted.

FIG. 1 is a schematic external view of an embodiment of the sleeve-shaped container of the present invention, showing a state in which an object to be stored is stored. FIG. 2 is a plan view of a blank sheet forming an embodiment of the sleeve-shaped container of FIG. The sleeve-shaped container 1 is formed by folding a blank sheet 1a of paperboard, and has a square tubular shape in which a bottom surface 2, a left side surface 3, a top surface 4, and a right side surface 5 are connected to each other, and the front and rear surfaces are open. ing. Here, the left side surface and the right side surface are referred to merely for the purpose of distinction, and it is arbitrary which one is left and which one is right. Further, a reinforcing plate 2a for reinforcement is laminated on the bottom surface 2 and bonded with a glue margin 2b.

The top surface 4 is formed with an entry portion 6 having a narrowly constricted shape with a central portion in the front-rear direction entering in the left-right direction. Then, for example, on the right side surface 5, a fold ruled line 8 that is convex inward toward the bottom surface 2 is provided from the apex 7 that enters the right side surface 5, and is provided on the right side surface 5 and is convex outward that extends in the front-rear direction. It has reached the fold ruled line 9. For this reason, the portion 5a on the top surface side of the outwardly convex fold ruled line 9 is pulled inward by the insertion portion 6 on the top surface 4 side, and the outwardly convex fold ruled line 9 side projects outward, so that it is inward. A mode in which the convex fold ruled line 8 is bent inward with the portion as the apex, and as shown in FIG. Can be.

The bottom surface side portion 5b of the right side surface 5 protrudes toward the outwardly convex fold ruled line 9, but a plurality of outwardly convex fold ruled lines may be provided, and a plurality of outwardly convex fold ruled lines may be provided. The bottom surface side portion 5b of the right side surface 5 may have a shape that bulges outward. For example, when the side surface of the lower object to be stored 12 has a bulge shape, it may have a shape that conforms to it. .. In that case, the inwardly convex fold ruled line 8 may reach the most outwardly convex fold ruled line on the top surface side.

The above configuration and effect are the same on the left side surface 3.

The insertion portion 6 is not only simply inserted, but is also provided with a convex fold ruled line 8 inward from the apex 7, so that the intruded shape can be easily maintained and the inwardly convex fold ruled line 8 is covered. It can be firmly contacted with the side portion of the stored object 11 and pressed, and the holding of the stored object 11 is suitably maintained. Since the same mode is applied to the left side surface 3, the mode in which the stored object 11 is sandwiched from the left and right is stable, and the mode is difficult to come off.

That is, conventionally, notches and slits for holding the stored object are formed by preparing a mold blade and the like, but in the sleeve-shaped container of the present invention, the paperboard is folded and pasted with a fold ruled line. Although it can be manufactured by a simple manufacturing method, it can be a sleeve-shaped container in which the stored object does not easily come off.

Further, as illustrated in FIG. 1, even when a plurality of tray-shaped items to be stored 11 and 12 are stored in a stack, the items to be stored 11 stacked on top are generally easy to fall off, but they are stacked on top of each other. Since the side surface of the stored object 11 is sandwiched by the inwardly convex fold ruled line 8 so as to be pressed from diagonally above, the lower stored object 12 is also difficult to come off, and the stored object can be hard to come off.

The shape of the insertion portion 6 may be linearly inserted as illustrated in FIG. 3A, or may be curvedly inserted as shown in FIG. 3B. The distance between the vertices 7 and 7 of the insertion portion 6 in the left-right direction may be appropriately set according to the size of the stored object, but it may be equal to or less than the width in the left-right direction of the stored object and is slightly narrower. You may set it so that it can be pinched more strongly.

Further, as illustrated in FIG. 4, the sleeve-shaped container of the present invention may have a form in which a notch 13 is provided on a side where the left side surface 3 and the right side surface 5 are in contact with the bottom surface 2. By fitting the side portion of the stored object 12 which is the lower side into the notch 13, the stored object 12 is more difficult to come off, and the upper side which is sandwiched between the apex 7 of the entry and is hard to come off. In combination with the object to be stored in No. 11, the mode can be further prevented from falling off.

When producing a blank sheet constituting the sleeve-shaped container of the present invention, it is appropriately selected from paperboards such as coated cardboard used for general carton containers and applied according to the weight and size of the container to be stored. Can be formed by folding a blank sheet made of paperboard. The basis weight of the paperboard is suitable those 100 to 500 g / ^{m 2,} it is more suitable that the 200 to 400 g / ^{m 2.}

FIG. 5 illustrates another form of the blank sheet constituting the sleeve-shaped container of the present invention, and is a plan view of an example of a blank sheet in which two vertices are provided at the insertion portion. In the example of FIG. 5A, for example, on the right side surface 5, the entrance portion 6 is provided with two entry vertices 7 and 7, and the right side surface 5 is provided with the vertices 7 and 7 toward the bottom surface 2. Convex fold ruled lines 8 and 8 are provided on the inside, and reach the outwardly convex fold ruled lines 9 provided on the right side surface 5 extending in the front-rear direction. The fold ruled lines 8 and 8 are gathered at one point on the outwardly convex fold ruled line 9. The vertices 15 in the opposite direction sandwiched between the vertices 7 and 7 are convex outward, and the fold ruled line 16 is also convex outward. The left side surface 3 has the same aspect as described above.

The blank sheet provided with the two vertices in the insertion portion may have a shape in which the vertices 7 and 7 of the entry are connected by a curve as shown in FIG. 5 (b). In the example of FIG. 5B, the inwardly convex fold ruled lines 8 and 8 extend in parallel toward the bottom surface. When two entry vertices 7 and 7 are provided in the entry portion 6 in this way, for example, as shown in FIG. 6A, when the outer shape of the stored object 17 is close to a circle. If there is only one vertex, holding tends to be unstable, but by holding at two vertices 7 and 7, it can be held in a more stable and hard-to-fall state. The effect of stabilizing the holding can be obtained even if the object to be stored has a rectangular shape.

When two entry vertices are provided in the entry portion 6, two vertices may be provided only on either the left or right side surface side. For example, as illustrated in FIG. 6B, the left side. One apex 7 may be provided on the surface side, and two vertices 7 and 7 may be provided on the right side. Further, three or more such inwardly convex fold ruled lines can be provided in the same manner, and can be appropriately provided according to the shape of the object to be stored.

Further, the sleeve-shaped container of the present invention includes a zipper portion 18 for tearing the sleeve, which is known in the conventional sleeve-shaped container, for example, as illustrated in FIG. 7, and a handle portion 19 which can be raised and used as a handle. Can also be provided.
