Description

  The present invention relates to a cover sheet that forms a design display structure of a packaging box.

  Today, packaging box designs are often displayed by printing a plate of the desired design and printing directly on the paper before being cut into the unfolded shape of the packaging box. In such a method, in addition to the cost required to manufacture the plate, there is a problem that it is not possible to flexibly cope with the actual situation of the design work.

  In addition, in order to confirm the appearance of the packaging box that has been designed in advance, a sheet or the like on which several types of design candidates are printed is prepared in advance and actually attached to the packaging box and viewed (for example, , See Patent Document 1 below), and such a method is unsuitable for mass production of packaging boxes in terms of production speed, sticking accuracy, and the like.

JP 2000-108528 A

  The present invention has been made in view of the above circumstances, and in the manual work of sticking a spread sheet on the surface of a packaging box, both the accuracy of the sticking position and the speed of sticking are satisfied, An object of the present invention is to provide a cover sheet having a structure in which the manufacturing method can be used in order to provide a manufacturing method of a packaging box that can increase the manufacturing amount of the product to a mass production level.

The means for solving the above-mentioned problem consists of a surface sheet having an adhesive layer over the entire back surface and a release sheet covering the adhesive layer, and is integrated with the side and top surfaces of the packaging box with the same shape and size. It is a cover sheet that has a perforation penetrating the surface sheet, the pressure-sensitive adhesive layer, and the release sheet, and has a slit that crosses the spread sheet only in the release sheet.
It is good also as a structure provided with the expansion | deployment sheet | seat which the whole side part continues in strip | belt shape, and it is good also as a structure provided with the some slit which divides | segments an expansion | deployment sheet substantially equally only in the peeling sheet of an expansion | deployment sheet.

  According to this cover sheet, an assembly process for forming a packaging box from packaging paper cut into a developed shape as shown below, and the surface of the packaging box has the same shape and size as the side and upper surface of the packaging box. A manufacturing method of a packaging box including a pasting step of pasting a matching integral development sheet is possible.

  That is, in this pasting process, a parting operation for separating a perforation representing the outer shape of the unfolded sheet from the cover sheet, and a release sheet in the region divided from the cover sheet are peeled off and positioned and pasted to the corresponding locations on the packaging box. This is a method for manufacturing a packaging box in which a sticking process comprising a fixing work to be attached is repeated a plurality of times until the sticking of the entire surface of the spread sheet is completed.

  By using the above-mentioned cover sheet, when the unfolded sheet is attached to the assembled packaging box, it is separated from the cover sheet for each part to be attached, and the packaging box is fitted to the notch produced by the division and positioned. After positioning, it is possible to fix while removing the release sheet, so that it is possible to prevent misalignment in the sticking process after the positioning process, and to stick to the packaging box accurately and easily. The As a result, it is possible to reduce the time and effort of the sticking process and increase the sticking speed to a sufficient mass production level.

  In addition, by assembling the packaging box and then pasting the developed development sheet in this way, the cost of plate production is not increased, and the design actually applied to the packaging box can be confirmed. And changes can be made relatively easily. In addition, the troublesome task of assembling the packaging box after sticking can be avoided, and as long as it satisfies that after the packaging box is assembled, the timing for performing the pasting process can be determined relatively freely, The degree of freedom for replacing the display according to the contents will be increased.

  By using a single unfolded sheet that is aligned with the same shape and size as the side and top surfaces of the packaging box, it is possible to maintain an appearance that is inferior to that when directly printed on the packaging box paper.

  When the packaging box has a rectangular parallelepiped shape, positioning can be performed easily and accurately by adopting a shape in which the four side surface portions are connected in a strip shape as the shape of the spread sheet.

Embodiments of a cover sheet according to the present invention and a method for manufacturing a packaging box using the same will be described below with reference to the drawings.
In the example shown in FIG. 1, an integrated unfolded sheet 5 is attached to the surface of a packaging box 2 assembled in a rectangular parallelepiped shape with the same shape and size as the four side surfaces 3 and the upper surface 4 of the packaging box 2. It is the cover sheet 0 used for the manufacturing method of the packaging box to do. Note that the two-dot chain line in FIGS. 1 to 4 is an imaginary line indicating a portion to be bent at the time of assembly.

  The paper of the packaging box 2 (wrapping paper 1) is formed by connecting the four side surfaces 3 of the packaging box 2 and the adhesive margin piece 7 in a line, and on the left (right) side of the side surface 3 on which the adhesive margin piece 7 is provided. A pair of convex pieces 9 each of which forms a bottom cover by connecting an upper cover formed by arranging the upper surface 4 and the insertion piece 8 in a row, and combining or gluing appropriately on the right (left) side of the four side surfaces 3. And the concave pieces 10 are alternately connected one by one, and further, the opposite side of the side face 3 where the convex pieces 9 are connected, and the support pieces 11 that support the upper lid are connected to each other (see FIG. 10). ). In addition, the two-dot chain line of FIG. 10 is a virtual line which shows the location which should be bent in the case of an assembly.

  On the other hand, the cover sheet 0 is composed of a surface sheet 5a having an adhesive layer 6 on the entire back surface and a release sheet 5b covering the adhesive layer 6, and is shaped like the outer shape of the unfolded sheet 5, and the surface sheet 5a, the adhesive layer 6, and A perforation that penetrates the release sheet 5b is provided, and a slit 5d that crosses the spread sheet 5 is provided only in the release sheet 5b (see FIG. 9).

  The spread sheet 5 according to this example has four side surface portions 3a of the sheet connected in a line in a row, and the upper surface portion 4a of the sheet is connected to the left (right) side of either one of the two ends of the band shape. (See FIGS. 1 and 9). The release sheet 5b in this example includes a slit 5d that crosses the upper surface portion 4a and the side surface portion 3a continuous therewith. In addition, in the form of a packaging box, for example, in a cylindrical packaging box, it may be composed of a single side surface portion 3a. The cover sheet 0 may be configured to include a plurality of slits 5d that divide the dimension in which the side surface portions 3a are continuous approximately evenly according to such a form, size, and the like.

  The manufacturing method of the packaging box taken using this example includes an assembly process for forming a rectangular parallelepiped packaging box 2 from the packaging paper 1 cut into a developed shape, and the packaging box 2 has four surfaces on the surface of the packaging box 2. It consists of the sticking process which sticks the integral expansion | deployment sheet | seat 5 which aligns with the one side 3 and the upper surface 4 with the same shape and size.

  The assembling process includes, for example, an inner mold that is shaped like a rectangular parallelepiped that is the outer shape of the packaging box 2, and the adjacent side surfaces 3 are bent so that they are kept at right angles, and the adhesive strips 7 overlap each other. 3 is formed into a rectangular tube shape, and one concave piece 10 is glued to either one of the adjacent convex pieces 9 and the two concave pieces 10 are combined to form each concave piece 10. This is completed by forming the bottom cover so that only one of the two projecting pieces 10a provided on the front side overlaps (see FIG. 10).

  Affixing process peels off part of the perforation 5c that represents the outer shape of the unfolded sheet 5 from the cover sheet 0, and peels off the release sheet 5b in the region divided from the cover sheet 0 to the corresponding part of the packaging box 2. The sticking process consisting of positioning and sticking fixing work is repeated a plurality of times until the sticking of the entire surface of the unfolded sheet 5 is completed (see FIGS. 2 to 7).

  For each part to which the unfolding sheet 5 is to be attached, in order from one end to the other end of the side surface portion 3a connected in a strip shape (from the left side to the right side in FIGS. 1 to 6), it is separated from the cover sheet 0, The packaging box 2 is fitted to the cutout portion 0a generated by the division, and positioning is performed. After the positioning, the release sheet 5b is gradually peeled off and stuck. Since the perforation 5c penetrates the front and back of the cover sheet 0, by dividing the entire thickness from the surface sheet 5a of the spread sheet 5 to the release sheet 5b from the cover sheet 0, the notched part 0a after the split is deepened. It can be obtained and is easy to use as a guide.

  Specifically, the unfolded sheet 5 (slightly more than one side surface) to be attached with at least one positioning is divided from the cover sheet 0, and one of the cutout portions 0a generated by the division is divided. The packaging box 2 is fitted on the end for positioning. That is, using the right angle that exists at the corner of the notch portion 0a and the two-direction edges forming the guide as a guide (see FIG. 2), while appropriately sliding the packaging box 2 along the band shape of the notch portion 0a, On the surface of the packaging box 2, the development sheet 5 separated from the cutout portion 0 a is attached along the edge of the side surface to be attached (see FIG. 3).

  The unfolded sheet 5 is further divided from the cover sheet 0, and the packaging box 2 is rotated while being slid to the newly separated side (90 degree rotation in a rectangular parallelepiped), and the unfolded sheet 5 is stretched to change its dimensions. And it sticks in the form wound up, giving appropriate tension which is the extent which the packaging box 2 does not deform | transform (refer FIG.3 and FIG.4). By repeating a series of operations from the division to the sticking through the slide and rotation of the packaging box 2, the entire spread sheet 5 is continuously stuck to the packaging box 2 (see FIGS. 5 and 6).

  By combining the above assembling process and the pasting process, the unfolding sheet 5 is integrated as a surface of the upper surface 4 and the side surface 3 of the packaging box 2 quickly and accurately, without causing any deviation or protrusion, and the packaging is assembled in a rectangular parallelepiped shape. A packaging box in which an integral unfolded sheet 5 that is aligned with the same shape and size as the side surface 3 and the upper surface 4 of the packaging box 2 can be manufactured on the surface of the box 2 (see FIG. 7).
