Description

The present invention relates to a packaging box and a partial mold used for manufacturing the same, and more particularly to a corrugated cardboard box which facilitates taking out a long object in the vertical direction and a partial mold used for manufacturing the same.

For example, a cardboard box is used to pack and transport a plurality of individually wrapped long products. FIG. 8 is a diagram showing a conventional method using the most general-purpose cardboard box called 0201 type (or A type). The 0201 type corrugated cardboard box 100 is provided in a state in which a front panel having flaps 120 on both sides, a back panel, and side panels on both sides are joined to form a body portion 110. At the time of use, the body 110 is expanded into a square cylinder, and then the flaps 120 on both sides of each panel are bent inward to form a rectangular parallelepiped packaging box. The 0201 type corrugated cardboard box is widely used because its outer flaps are butted, the area used for corrugated cardboard is small, it is highly versatile and economical, and its structural strength as a box is high.

As shown in FIG. 8, for example, a plurality of individually wrapped plate-shaped long products 130 are arranged side by side so as to be vertical in the width direction, packed in a cardboard box 100, and packed again at the transportation destination as shown in FIG. The top flap 120 can be opened to remove the individual product 130.

However, as shown in FIG. 8, after a plurality of products 130 are packed in a cardboard box 100 and transported, there may be a case where the products 130 are individually vertically taken out at the transportation destination, that is, at the site where the product 130 is used. In particular, when the site where the long product 130 is used is not very large, such as a medical site, if the cardboard box 100 is left as it is, the floor area will be sacrificed, the effective use of space will be limited, and the movement when personnel move. It also interferes with the line.

As a conventional technique for taking out a product from a corrugated cardboard box, Patent Document 1 (Japanese Patent Laid-Open No. 2019-94075) provides a corrugated cardboard in which notches 26 and 27 are provided in the top panel 1 so that the top panel can be opened from there. The case is described. However, in the corrugated cardboard case described in Document 1, in order to take out the PET bottle or the glass bottle inside, the cut portion 26 that divides the top surface 1 into substantially four is opened on both sides from the central portion thereof, and the cut portion 26 is further generated 4 It was necessary to open the two cut pieces 29, 30, 31 and 32, respectively, which was still troublesome. Further, the corrugated cardboard case of Patent Document 1 does not allow a long object to be taken out in the vertical direction.

JP-A-2019-94075

The problem to be solved is that the individual products 130 cannot be easily taken out in the vertical direction from the packing box in which the long product 130 as shown in FIG. 8 is packed. In view of this problem, it is an object of the present invention to provide a packaging box in which the side portion of the 0201 type corrugated cardboard can be easily opened by simple and inexpensive additional processing.

The present invention includes a body portion formed by joining a front panel, a right side panel, a back panel, and a left side panel, and a bottom flap and a top flap extending on both sides of each panel, and each panel is provided. The front panel, the right side panel, the back panel, and the back panel of the packing box are formed by bending the seams inward to form a square tube, and further bending the bottom flap and the top flap inward to form a box. At least one panel of the left side panel is a notch portion that is an intermediate portion of the panel and extends intermittently from the height central portion of the panel to both ends of one side side of the panel. The bottom flap and the top flap of the adjacent panel sharing the side side with the panel having the cut portion each have a first cutout portion at the outer end portion of the side side that joins the cut portion. It is characterized by that.

The packaging box of the present invention has an indication indicating the position or orientation of the adjacent panel as an aid for orienting the packaging box with the adjacent panel sharing the side surface with the panel having the notch as the top surface. It is preferably provided on one or more panels or flaps.

It is effective that the packing box of the present invention further includes an interior material folded into a U-shape in cross section slightly smaller than the inner size of the packing box.

In the packaging box of the present invention, the bottom flap having the notch and the top flap each further have a second notch at the side end portion opposite to the side on which the notch is provided. A packing box that features that.

The present invention further relates to a partial mold for additional use in the manufacturing process of JIS code 0201 type corrugated cardboard box, in which the partial mold is at least one of the front panel, the right side panel, the back panel, and the left side panel of the corrugated cardboard box. A notch making portion for intermittently providing a notch in any one of the panels from the central portion in the height direction of the panel to both ends of one side side of the panel, which is an intermediate portion of the panel. A first for providing a first notch at the outer end of the side that joins the notch, respectively, on the bottom flap and the top flap of the panel that provides the notch and the adjacent panel that shares the side. It is characterized by having a notch making part.

This partial mold further cuts the bottom flap and the top flap of the corrugated cardboard box on which the first notch is provided, and a second cut on the side edge opposite to the side on which the first notch is provided, respectively. It is effective to provide a second notch making portion for providing the notch.

In the packaging box of the present invention, any of the front panel, the right side panel, the back panel, and the left side panel constituting the body portion is provided with a notch that can be easily cut by pulling up by hand, and is continuous with the notch. Since the first notch is provided so that the flaps on both sides do not interfere with other panels when the adjacent panel is opened, the panel on the side of the packing box is opened from the sealed state by continuing to pull up the notch. The contents can be taken out. Therefore, for example, a cardboard box containing a plurality of individually wrapped long products can be placed vertically, and the top surface of the cardboard box can be easily cut open to take out each product. It is possible to secure the flow line of personnel and improve the safety of the site of use.

In the packaging box of the present invention, by providing an interior material folded into a U-shape with a cross section slightly smaller than the inner dimensions of the packaging box, the flaps on both sides of the packaging box are individually opened and closed when the side panel of the packaging box is opened and closed. It can be opened and closed smoothly without getting caught in the product.

Further, in the flap provided with the first notch portion, the notch portion is provided by providing the second notch portion (chamfering) at the outer end portion of the side side opposite to the notch portion. It is possible to prevent the corners of the flaps from cutting hands after the provided flaps are completely opened.

The partial type for manufacturing a corrugated cardboard box of the present invention is made of a 0201 type corrugated cardboard by providing a notch making part and a notch making part necessary for making the packaging box according to the present invention from the 0201 type corrugated cardboard box. The packaging box of the present invention can be easily manufactured in addition to the manufacturing process.

Top flaps 11a to 11d and bottom flaps 12a to 12d (hidden in FIGS. 2 and 3) are provided on both the upper and lower sides of the 10a to 10d.

However, unlike the conventional 0201 type corrugated cardboard box, the packing box 1 of the present invention has a side 13 on one side of the right side panel 10c from a portion 15 which is the center of the panel 10c in the vertical direction and is separated from the side 13. A notch 17 (perforation for opening) extending intermittently in a dotted line is provided in two directions to both end portions 13a and 13b. Further, as shown in FIGS. 1 and 2, the side sides of the flaps 11a and 12a continuous with the notch 17 are R-processed, that is, the first notch 19a whose outer end is curvedly cut off. It forms 20a.

In the embodiment shown in FIGS. 1 to 3, the apex portion 15 of the notch portion 17 is not a mainly dotted intermittent notch but a semicircle so that the user can easily turn this portion 15 with a thumb or the like at the time of opening. It is formed as a continuous notch. On the other hand, the intermittent notch 17 is composed of a notch line in which a substantially L-shaped short notch is intermittently formed. However, the apex portion 15 of the notch portion 17 does not have to be semicircular, for example, may have a triangular shape, a quadrangle, or other polygonal shape, or may be composed of intermittent notches instead of continuous notches. good. In the embodiment shown in FIG. 1, a short radial notch is provided so that the apex portion 15 can be easily turned over. Further, the intermittent cut portion 17 may be a cut in another form such as a Y-shape, an I-shape, or a T-shape instead of a substantially L-shape as long as it functions as a perforation for opening. .. As an example, FIG. 7 shows a modified example in which the cut portion 17 is a Y-shaped cut portion 47. Further, in the illustrated embodiment, the cut portion 17 extends substantially linearly from the apex portion 15 to both end portions 13a and 13b of the side side 13, as long as it also functions to open and open along the perforation. , It may be a curved line or a polygonal line. Further, the position of the apex portion 15 can be appropriately determined in consideration of the implementation conditions such as the size of the panel of the corrugated cardboard box to be applied.

Optionally, as best shown in FIG. 1, in the flaps 11a, 12a of the front panel 10a, the outer end of the side side opposite to the first notch 19a, 20a is also R-processed, that is, the first 2 Notches 19b and 20b can be provided. Further, as best shown in FIG. 3, a cargo handling instruction mark 22 according to JIS Z 0150 indicating the correct upward position of the packaged cargo during transportation or storage can be provided. In addition to the mark 22, other indications such as characters and symbols may be provided, and the position and number thereof can be arbitrarily determined.

How to use the packing box 1 configured in this way will be described. FIG. 4 is a diagram for explaining a procedure for packing, for example, a plurality of individually packaged long products in the packing box 1 of the present invention. Although not necessarily essential, the packing box 1 of the present invention may be conveniently used together with a predetermined interior material 30 depending on the packaged material. As shown in FIG. 4, the interior material 30 used together with the packing box 1 for packing a plurality of long products is composed of a corrugated cardboard sheet folded into a U shape having a cross section slightly smaller than the inner dimensions of the packing box 1. This is placed in the packing box 1 assembled as shown in FIG. 2 (step of circle number 1). At this time, the upper surface 30a of the interior material 30 is opened in order to insert the product 130 thereafter. In this state, a plurality of individually packaged plate-shaped long products 130 are arranged side by side so as to be vertical in the width direction and packed in the packing box 1 (step of circle number 2). Finally, the upper surface 30a of the interior material 30, the inner flaps (flaps 11a and 11b) of the packing box 1 and the outer flaps (flaps 11c and 11d) are closed in this order, and the appropriate parts are fastened with adhesive tape or the like. It becomes the state of, and can be transported to the destination.

FIG. 5 is a diagram for explaining a method of taking out the product 130 from the packing box 1 at the place of use. At the final destination of the packing box 1, that is, the place where the product 130 is taken out, the packing box 1 is erected so that the front panel 10a faces the top surface according to the cargo handling instruction mark 22. Next, as shown in FIG. 5A, when the apex portion 15 of the cut portion 17 is pinched with a finger and pulled up, the perforation is broken and the cut portion 17 can be opened along the cut portion 17. At this time, the adhesive tape on the peripheral edge of the front panel 10a is peeled off or cut with a knife at the time of packing. If the notch 17 is pulled up as it is, the front panel 10a can be opened in a hinge manner as shown in FIG. 5 (b). As shown in FIG. 5B, the corners of the flaps 11a and 12a on both sides of the front panel 10a are R-processed to provide the notches 19a and 20a, so that these portions interfere with the right side panel 10c. Therefore, it does not interfere with the opening of the front panel 10a. Further, as shown in FIG. 5B, since the flaps 11a and 12a are separated from the product 130 via the interior material 30, the flaps 11a and 12a are attached to the individual products 130 when the front panel 10a is opened and closed. Will not get caught. When the packing box 1 is opened as shown in FIG. 5C in this way, individual products can be taken out.

In the fully open state as shown in FIG. 5C, the corners of the flaps 11a and 12a near the product 130 are chamfered by the second notches 19b and 20b, so that a person can take out the product 130 when taking it out. Prevents contact with sharp corners and damage. Further, when the product 130 taken out as needed is returned to the packing box 1, the product 130 is inserted into the U-shaped interior material 30 so that the product 130 has an inner flap on the opposite side (in FIG. 1). It can be inserted to the bottom without being caught by the flaps 11b and 12b) shown. With the above configuration, a plurality of long packages such as the product 130 can be individually taken out from a direction different from the direction in which they are put in the packing box 1. In particular, as in this embodiment, the packing box 1 containing a long object is placed upright in the vertical direction, and the top surface of the packing box 1 is opened so that the individual products 130 can be taken out. Therefore, the packing box 1 is a conventional method. In other words, as compared with the case where the space is opened and taken out with the arrangement shown in FIG. 2, the space can be effectively used to secure a wide flow line.

The manufacturing method of the packing box 1 of the present invention will be described below. The packing box 1 according to the present invention can be manufactured by adding a slight additional step to the manufacturing process of the JIS code 0201 type corrugated cardboard box. FIG. 6A is a diagram showing a die cutter design to be added to the production of the 0201 type corrugated cardboard box, and FIG. 6B is a diagram of a rotary die cutter using the design of FIG. 6A in the corrugated cardboard production process. It is a perspective view which shows the Example applied to the partial type 42. As shown in FIG. 6A, in the manufacturing equipment of the 0201 type corrugated cardboard box, the notch making section 37 corresponding to the notch 17 and the first notch making section 39a corresponding to the first notch 19a, 20a, A die die cutter provided with 40a and second notch creating portions 39b and 40b corresponding to the second notch portions 19b and 20b is introduced. When using a flat plate die cutter that punches a corrugated cardboard sheet from above, the design of FIG. 6A is applied to a flat punching die. When using a flexo folder gluer in which a corrugated cardboard sheet is continuously flowed and processed by a rotary die cutter, a partial mold 42 such as a cylinder cut in half as shown in FIG. 6 (b) is used as a roller of the rotary die cutter. It is attached to form a notch 17 and first and second notches 19 and 20 before the bending step. Further, in the printing process on the corrugated cardboard sheet, the cargo handling instruction mark 22 (arrow in FIG. 1) as shown in FIG. 1 is printed. Since the other steps are the same as the manufacturing process of the 0201 type corrugated cardboard box, detailed description thereof will be omitted in this specification. After obtaining the printed / cut corrugated cardboard sheet as shown in FIG. 1, the panel is bent between the panels 10a and 10c and between the panels 10b and 10d in the bending step, and the glue margin 45 provided on the panel 10c in the gluer step is applied to the panel. The packing box 1 of the present invention is completed by gluing the end portion of 10b.

Although the packaging box of the present invention and one embodiment of the partial mold for manufacturing the same have been described above, those skilled in the art will have various modifications and modifications regarding the size of the packaging box, the mode of the notch 17, and the like. You will easily understand what can be achieved. For example, the rounding of the notch 17 and the flaps of the adjacent panels associated with it is the same or different for another corner of the packing box, as long as the notch 17 does not overlap the glue margin 45 when the packing box is assembled. It may be provided in the orientation, or may be provided at a plurality of corners so that the user can take out the product from a desired direction. Further, in the above embodiment, the R processing of the flap is provided with a curved notch, but if it does not interfere with another panel when the panel is opened, another shape such as a stepped or linear notch may be used. There may be.

Further, the packing box of the present invention is not limited to the one manufactured as a corrugated cardboard box, and can also be realized as a packing box manufactured of other materials such as cardboard. Although the packing box of the described embodiment is used for packing a long product individually wrapped, the present invention is not limited to its use, and has a wide range of uses from products such as stationery and medical equipment to products such as building materials. Can be considered.
