Description

[Detailed explanation of the invention] (1) Industrial application field This invention consists of two individual cases connected back to back, handled as a single case during transportation and storage, and divided into two pieces according to the sales volume. This is about a case that can be assembled.

(2) Conventional technology A conventional assembled case is formed by forming a rectangular cylindrical case unit from opposing side walls and opposing end walls, and connecting these two case units back to back with the end walls. The wall was provided with a cutting tape or perforations for cutting off the upper half of the package.

(3) Problems that the invention aims to solve However, this assembled case is
If you tear off the transverse separator line to make a tray-shaped case in order to display it as is and make it easy to take out the items inside, if you try to lift and move it by supporting the bottom with your hands, the back-to-back connecting parts will break against the outer peripheral wall. It had been torn apart along with the upper half, making it weak, so it had the drawback of easily breaking in two from this point.

(4) Means for solving the problem A transverse separation line for opening is provided on the pair of end walls located on the outside, and a continuous side wall with two side walls as one side has both ends connected to the transverse separation line. A frontal substantially chevron-shaped separation line is provided in the central portion so as to straddle the connection band.

(5) Function When this assembled case is opened by tearing apart the transverse separation line and the chevron-shaped separation line and removing the upper part thereof, the connected back-to-back end walls and their connecting bands will remain as they are. (See Fig. 4) (6) Example As shown in Fig. 1, the assembled case of this invention is made of paper pattern base material a (second
(see figure), bend it and glue the main parts to form a rectangular cylindrical case unit 1 (see figure 3), and connect the two case units 1 in a divisible manner to assemble the case body 2. is formed, and an opening tear line 3 (details will be described later) is provided on the outer circumferential wall of the assembled case body 2 to leave a connecting portion between the two case units 1.

As shown in FIG. 2, the paper pattern base material a has opposing side walls 4, 4, opposing outer end walls 5a and inner end walls 5b, and a small joint width extending to the edge of the inner end wall 5b. 6 are connected to each other horizontally via a vertical fold line 7, and a narrow connecting piece 9 is provided protruding from the edge of one side wall 4.
On both side walls 4, outer lid flaps 11 which abut against each other when the top surface is sealed are connected to the upper edge via a horizontal fold line 10, and an inner bottom flap 13 is connected to the lower edge via a horizontal fold line 12, and the outer end An inner lid flap 14 is connected to the upper edge of the wall 5a via a transverse fold line 10, and a triangular glue margin 15 is provided at the end of the outer end wall 5a and inner end wall 5b via a transverse fold line 12 to the lower edge. Has bottom sealing notch 16
An outer sole flap 17 that engages the two is connected.

Further, on the outer end wall 5a, a transverse separation line 3 for opening made of cut tape is provided on the inner surface slightly below the center.
A is attached, and an I-shaped notch puller 18 is provided at the center of this transverse separation line 3a.

The both side walls 4 have a diagonal line starting from the upper end of the vertical fold line 7 on the inner end wall 5b side, descending laterally, then bending, descending vertically, and further bending to become approximately horizontal, and the outer end wall 5a. A substantially L-shaped separation line 3b that continues to the transverse separation line 3a is provided. The parting line 3b of the side wall 4 is formed by using a cut tape as an extension of the horizontal parting line 3a, and perforating the perpendicular part and the diagonal part bent from the straight part.

This assembled case uses the above-mentioned paper pattern base material a, and as shown in FIG.
The inner bottom flap 13 and the outer bottom flap 17 are bonded together with a glue margin 15 to form an automatically opening/closing bottom surface, and a rectangular cylindrical case unit 1 with an opening at the top is formed. Using these two case units 1, as shown in FIG. 1, align the inner end walls 5b without the inner lid flap 14 back to back, and overlap the connecting piece 9 of the other case unit 1 on the outer surface of the side wall 4. The two case units 1 are connected by fixing using the matching stitch wire 19, and the packaging is completed by folding and sealing each lid flap.

In this assembled case, a pair of substantially L-shaped separation lines 3b forms a front chevron-shaped separation line on a continuous side wall that includes two side walls 4 as one side.

As shown in FIG. 4, the assembled case is opened by inserting a finger into the handle 18, holding the end of the cut tape, cutting along the transverse separation line 3a and the L-shaped separation line 3b, and removing the upper wall piece. The tray-shaped case has continuous side walls with an inverted T-shape, leaving both inner end walls 5b and a connecting band including a joint allowance 6 and a connecting piece 9. In this tray-shaped case, the connection part remains intact, so there is no change in the strength of the connection between the two cases 1, and even if you lift the case by supporting the bottom with your hands while the item is still inside, it will not break in half due to the weight of the item. Nothing happens.

5, 6, and 7 are an exploded view of a single case, an assembled perspective view of the single case, and a perspective view of the case in an unsealed state, showing other embodiments of the invention. The pattern base material a of the case unit 1 in this example is:
The opposing side walls 4, 4, the opposing outer end wall 5a/inner end wall 5b, and a seam allowance 6 are laterally connected via a vertical fold line 7, and the both side walls 4 have a horizontal fold line 10 at the upper edge.
An outer lid flap 11 is connected to the outer end wall 5a through a horizontal fold line 12, and an outer bottom flap 17 is connected to the lower edge via a horizontal fold line 12. are connected to each other, and an inner bottom flap 13 is connected to the lower edge via a horizontal fold line 12.

Further, the outer end wall 5a is provided with a transverse separation line 3a consisting of a perforation slightly below the center, and the both side walls 4 are provided with a transverse break line 3a starting from the upper end of the vertical fold line 7 on the inner end wall 5b side. 10, a substantially L-shaped separation line 3b is provided which is bent after being slightly along the line 10 and continues to the transverse separation line 3a of the outer end wall 5a. The horizontal line portion of this separation line 3b also extends to the seam allowance 6.

The assembled case of this example uses the above-mentioned paper pattern base material a, and as shown in FIG.
A case unit 1 with upper and lower openings is formed by bending from the bottom and using a seam allowance 6, and using two case units 1, the inner end wall 5b without a flap is placed back to back, and the outer lid flap 11, the side wall 4 and the outer bottom flap 17 are formed. When adhesive tape 20 (see the chain line in FIG. 6) is adhered to the abutting edges of the two cases 1, the two cases 1 are connected. FIG. 7 shows a tray-shaped case (the left half is not shown) which has been opened by tearing apart the separation lines 3a and 3b of this assembled case and removing the upper half.

If the assembled case of each of the above embodiments is to be divided into individual cases according to necessity, the connecting piece 9 (first embodiment) or adhesive tape (second embodiment) can be cut using a knife.
carve out. Incidentally, if a separation line consisting of perforations or the like is attached to the connecting piece 9, division becomes easy.

Note that the case unit 1 of this invention is not limited to the lid flap and bottom flap shaped as described above.

(7) Effects As stated above, when the assembled case according to this invention is opened at a store or the like by removing the upper half from the separation line to form a tray-shaped case, the joint between the two cases remains intact. Because of this, there is no change in the strength of the connection, so there is no risk of it breaking in two even if you support the bottom with your hands while carrying the item, and the chevron-shaped connection part has relatively high pressure resistance. Therefore, you can stack multiple pieces and carry them around.
