Abstract

<P>PROBLEM TO BE SOLVED: To provide a wrap-around box which allows an operator to easily insert a hand into a gap between a peripheral wall and contents, and to take the contents out of the gap. <P>SOLUTION: A pair of flat plates 1 opposed to each other, and side plates 2 opposed to each other so as to be at right angles with respect to the flat plates are cylindrically extended to form a peripheral wall that wraps goods. Then internal flaps 4 and external flaps 5 are extended from the side plates 2 and the flat plates 1, respectively, and the internal flaps 4 and the external flaps 5 are successively folded, and the external flaps 5 are stuck to front surfaces of the internal flaps 4 to thereby seal the box. The flat plate 1 and the external flap 5 extending from the plate have folding lines 6 formed therein so as to diagonally extend from the tip center of the external flap 5 to both lateral ends of the flat plate 1. When the flat plate 1 and the external flap 5 are distorted outward along the folded lines 6, the gap into which the operator can insert the hand is secured between the flat plate 1 and a can C as the content, and therefore the operator can easily take out the can C. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a cardboard wrap round box used for collective packaging of beverage cans and the like.

  Generally, a wrap round box that collects and wraps beverage cans such as beer is provided with a tear strip such as a cut tape so that it can be divided into trays and opened in a horizontal state. In order to remove the required amount of beverage cans and store the remaining amount without bulking, it is often opened from the upper end face in a vertically placed state.

  However, at this time, since there is no gap for putting a hand between the peripheral wall and the beverage can and it is difficult to take out the beverage can, in Patent Document 1 below, one plane plate forming the peripheral wall is cut over the passage piece. A fold line extending diagonally from the edge to the diagonal is inserted, and when opening from the end surface, the flat plate is bent outward along the fold line so that the opening can be enlarged so that the beverage can can be easily taken out. What has been proposed is proposed.

  However, in the wrap round box as described above, since the passage piece and the flat plate are strongly bonded with a hot melt adhesive, when the flat plate is bent along the fold line in the oblique direction, the passage piece There is a problem that it is difficult to peel off.

  Then, this invention makes it a subject to provide a wrap round box which can put a hand between a surrounding wall and the contents and can take out the contents easily.

  In order to solve the above-mentioned problems, the present invention forms a peripheral wall that encloses an article by connecting a pair of opposing flat plates and a pair of side plates opposing each other at right angles to each other in a cylindrical shape. In the wrap round box, the inner flap is extended from each side plate, the outer flap is extended from each plane plate, the inner flap and the outer flap are bent sequentially, and the outer flap is attached to the front side of the inner flap and sealed. A crease line extending obliquely from the center of the front end of the outer flap to both sides of the flat plate is provided in the face plate and the outer flap connected thereto.

  In the wrap round box according to the present invention, if the plane plate and the outer flap are bent outward along the crease line, a gap is formed between the plane plate and the contents. The contents can be easily taken out by hand.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, in the corrugated blank of this Lapland box, each pair of flat plates 1 and side plates 2 are alternately arranged, and the outer side of one flat plate 1 is a cutting edge on the outer periphery of the blank. The passage piece 3 is connected to the outside of the other side plate 2. Inner flaps 4 are connected to both ends of each side plate 2, and outer flaps 5 are connected to both ends of each flat plate 1.

  One flat plate 1 and the outer flap 5 at one end connected to the flat plate 1 are provided with crease lines 6 extending obliquely from the center of the front end of the outer flap 5 to the other end corners on both sides of the flat plate 1. 3 also has a crease line 6 that overlaps the crease line 6 of the flat plate 1 during assembly. The crease line 6 is a ruled line entered from the back side of the cardboard.

  Moreover, the cut tape 7 used for opening at the time of horizontal placement is continuously stuck to the back surface of each side plate 2 and the inner flap 4 connected to both ends thereof, and the knob 8 is provided at the center of the side plate 2. Is formed with a cut.

  When assembling this blank and packaging the accumulated cans C as shown in FIG. 2, the pair of flat plates 1 and side plates 2 are folded into a square tube shape, and the passage piece 3 is connected to one flat plate. By pasting on the back surface of the face plate 1, a peripheral wall that wraps the can C is formed, and the inner flap 4 and the outer flap 5 are sequentially bent and bonded together, and both end surfaces are closed.

  When taking out the can C from the lap land box with such a wrap round box placed vertically, the outer flap 5 containing the crease line 6 is set to the top side, as shown in FIG. The outer flap 5 on the side is peeled off from the inner flap 4 and stood up to open the top surface.

  When one flat plate 1 and the outer flap 5 on the top surface side are bent outward along the crease line 6, a gap is formed between the flat plate 1 and the can C, and a hand is inserted into the gap. The can C can be easily taken out by placing a hand on the end face of the can C.

  In addition, in such a wrap round box, it is not necessary to perform cutting edge processing that may impair the strength in the packaging state, and the suitability for a packaging machine for assembling a blank and packaging the can C is reduced. Nor.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, description of the part which is common in the said 1st Embodiment is abbreviate | omitted here, and only the difference with 1st Embodiment is mentioned.

  As shown in FIG. 4, in the corrugated blank of this wrap round box, one flat plate 1 and the outer flaps 5 at both ends connected to the flat plate 1 are extended from the center of the front end of each outer flap 5 to both sides of the flat plate 1. The crease lines 6 extending diagonally intersect with each other so as to be vertically symmetrical. The passage piece 3 is also provided with a crease line 6 that overlaps the crease line 6 of the flat plate 1 during assembly.

  When assembling such a blank and packaging the accumulated cans C as shown in FIG. 5 and taking out the cans C from the wrap round box with the wrap round box placed vertically, outer flaps at both ends Since the crease line 6 is included in 5, no matter which end face is on the top surface side, as shown in FIG. 6, the top surface side is opened, and the one flat plate 1 and the top surface side outer flap 5 are attached. The can C can be easily taken out by bending outward along the crease line 6.

  In addition, in each said embodiment, although what put the crease line 6 only in one plane plate 1 and the outer flap 5 connected to this was illustrated, in the case where it cut | disconnects with the cut tape 7 at the time of horizontal placement, and is set as a tray state If it is not necessary to consider the strength, the crease line 6 may be put in both the flat plates 1 and the outer flap 5 connected thereto.

  In addition, the crease line 6 is a ruled line entered from the back side of the corrugated cardboard, but the crease entered from the back side or the front side of the cardboard and the front and back sides of the corrugated cardboard as long as the strength in the packaging state and tray state is not impaired It is good also as a lead rule | interval by which the cut | interruption penetrated in turns alternately.

  In addition, the crease line 6 is inserted so as to extend obliquely from the center of the front end of the outer flap 5 to the other end corners on both sides of the flat plate 1, but the angle between the two crease lines 6 is set wide. The outer end of the crease line 6 may reach the middle part of the ridge line between the flat plate 1 and the side plate 2.

  In addition, although a rectangular parallelepiped with each ridge portion illustrated is illustrated, even in a polyhedral wrap round box with chamfered ridge portions, a crease line 6 is put in the flat plate 1 and the outer flap 5 connected thereto. Thus, the same effect can be obtained.
