Abstract

PROBLEM TO BE SOLVED: To provide a different-shaped box which is produced by combining a top paperboard (bottom paperboard), that is made of cardboard and has a straight-line or concavely-curved-line circumference, with a side-face trunk paperboard, that is stuck to the circumference of the top paperboard (bottom paperboard) and in which a forming wooden model does not have to be required, an investment and a working space can be made smaller and the different-shaped box can be offered at a fixed price regardless of production/orders of a large or small lot.SOLUTION: A method for producing the different-shaped box, which is produced by combining the top paperboard 2 (bottom paperboard), that is made of cardboard 1 and has the straight-line or concavely-curved-line circumference, with the side-face trunk paperboard 3, that is stuck to the circumference of the top paperboard (bottom paperboard), comprises the steps of: beforehand cutting the top paperboard (bottom paperboard) and the corresponding side-face trunk paperboard; sticking one side of a double-sided adhesive tape 4 having ultrathin width to the lower inside of the side-face trunk paperboard to form an adherend plane 5; temporarily sticking the adherend plane to the circumference of the top paperboard (bottom paperboard) to form a different-shaped box body; applying an adhesive 6 to a temporarily stuck portion; and normally sticking the top paperboard (bottom paperboard) to the side-face trunk paperboard.

Description

The present invention is a deformation box (commonly referred to as a deformation box) that is made of cardboard and has a combination of a top board (soko paperboard) that has a straight or concave periphery and a side shellboard that is bonded to the periphery. The present invention relates to a manufacturing method and its deformation box.

Conventionally, in order to create a heart-shaped deformed box in plan view, the plywood 19 is cut out into a heart shape to form a “wood pattern 24” of the wooden outer frame 20 and the wooden inner frame 21, and simultaneously corresponds to the wooden inner frame 21. A cardboard topboard (sokoboardboard) 22 having a shape to be formed and a side shellboard paper 23 corresponding to the periphery of the topboard are prepared separately. The wooden frame outer frame 20 is fitted with the lower side portion of the cardboard sideboard board 23 made of cardboard in advance along the inner wall surface thereof, and is made in advance in the fitted side barrelboard 23. Put the cardboard top board 22, put the wooden inner frame 21 on it and push it down, and after pushing it out, take out the wooden inner frame 21, and glue the abutment part of the side shell board 23 and the top board 22 Further, when the top board 22 is fitted more than double, it is adhered in the same manner as before, and when this adhesion is dried, the assembly box formed by the side body paper board 23 and the top board 22 is removed from the wooden outer frame 20. remove. Thereafter, if necessary, decorative paper is separately attached to the entire surface or a part of the side body paperboard 23 and the top paperboard 22. The saw board is used for the body box and the top board is used for the cover box. However, since there are dimensional differences, it is necessary to make the wooden outer frame 20 and the like twice.

However, with this conventional method, a large number of molds for molding (minimally, the mold for the body box and the cover box are required) to increase the production quantity, and the initial investment amount increases. There are difficulties.

Therefore, the present invention requires a molding die in the production of a deformed box made of cardboard and bonded with a combination of a top board (soko paperboard) with a straight or concave curve around it and a side shellboard. In this way, the investment amount is reduced and the work space is also reduced so that a deformed box can be provided at a fixed price regardless of the production / ordering of a large number of lots and small lots.

In a deformed box made of cardboard and combining a top board (Soko board) with a straight or concave curve around it and a side shell board around it, the top board (Soko board) and this top board are supported. Cut the side paperboard in advance, glue one side of the ultra-thin double-sided adhesive tape inside the bottom side of the sideboard paperboard to form an adhesive surface, and temporarily bond this adhesive surface around the top board (soko paperboard) A deformed box body was formed, and an adhesive was applied to the intersection of the top board (soko paperboard) and the side shellboard of this deformed box body, so that the topboard (sokoboard) and the side shellboard were fully bonded. It is a manufacturing method of a deformation box.

As an effect of the present invention, since a molding die is not required, the investment amount for making a die is reduced and the work space can be reduced, and it can be deformed at a fixed price regardless of manufacturing / ordering of many lots and small lots. Can provide a box.

In a deformed box made of cardboard 1 and bonded by combining a heart-shaped top board (soko board) 2 with a straight or concave curve around it and a side shell board 3 around it, the top board (soko board) ) 2 and the side body paperboard 3 corresponding to the top board 2, CAD (CAD) (A design in which a model consisting of product shape and other attribute data is created inside the computer and analyzed and processed.) Cut in advance by a cutting machine or a punching machine operated by a mechanism, and one side of an extremely narrow double-sided adhesive tape 4 corresponding to the thickness of the top board 2 is bonded to a part or all of the inside of the lower side of the side body board 3 The adhesive surface 5 is formed, and the adhesive surface 5 is temporarily adhered to the corresponding periphery of the top board (soko paperboard) 2 to form a deformed box body 8, and the top board (soko paperboard) of the deformed box body 8 is formed. Apply adhesive 6 to the intersection of 2 and side copper board 3 This is a method for manufacturing a box, characterized in that the top board (sawboard) 2 and the side copper board 3 are permanently bonded. When making the top board (saw board) 2 double, put another top board 2 and bond. It should be noted that a fold line 7 may be provided at a point (for example, a position corresponding to a heart-shaped lead-in portion and a pointed portion) of the side body paperboard 3 as shown by a dotted line in FIGS. Further, it is preferable that the both ends of the side body paperboard 3 are connected by bonding a connecting piece (not shown) formed of friend paper or the like. Although it is desirable that the temporary bonding and the main bonding match, it is not always necessary to match.

As shown in the enlarged partial cross-sectional explanatory diagram of FIG. 2, the deformation box thus formed is temporarily bonded to the inner side of the lower side of the side body paperboard 3 and the periphery of the top board (soko paperboard) 2 via a double-sided adhesive tape 4. At the same time, the adhesive 6 is applied to the temporarily bonded portion and finally bonded. Although it is desirable that the temporary adhesion portion and the main adhesion portion coincide, it is not always necessary to coincide.
