Description

[Detailed Description of the Invention] The present invention relates to a packaging container for stacking and storing a required number of cup-shaped containers for foods and drinks.

Conventionally, this type of packaging container has the following characteristics: it can be manufactured at low cost, it has a robust structure and can firmly hold the objects to be stored, the objects to be stored are visible and have a good appearance, and the objects to be stored are easy to handle. However, it has been difficult to satisfy all of these requirements. That is, in order to make the product more robust and have a good appearance, the structure becomes more complicated, which inevitably increases the cost.

This invention aims to solve such problems.
At the upper edge of a bendable thin rectangular plate made of paper or plastic, both the upper half contour line and the lower half contour line have an arc shape that bulges outward. The required number of folding pieces that protrude upward and are formed into folded lines by recessing the lower half contour line are arranged in parallel at appropriate intervals, and the branch pieces extend upward from the upper edge other than the folded pieces. A disc is attached to the tip of the protruding part, and the part that goes down from the upper edge by the required distance has the same shape as the folded piece part of the upper edge, and the outline of the upper half is a cut line, and both ends of the disc are attached. A required number of folding pieces having a notch and a lower half contour line formed in a polygonal line are connected by perforations and arranged in parallel, and at least one of the folding pieces has an upper half contour line. A fan-shaped window hole is provided at the top, and below the fan-shaped window hole, a required number of folded pieces and windows connected by similar perforations are formed to form an unfolded body, and both edges of this unfolded body are connected. It is assembled into a cylindrical shape, and the folding pieces other than the upper edge are folded inward from the fold line to serve as a mounting stand for the object to be stored, and the disk and folding pieces at the upper edge are folded inward. The above object is achieved by forming a lid body, and at least openings such as windows on the outer circumferential surface are covered with a transparent sheet.

The figures show an embodiment of the present invention, in which Fig. 1 is a plan view of the developed body, Fig. 2 is a perspective view of the assembled state, and Fig. 3 is a longitudinal sectional view of the assembled state.
FIG. 4 is a perspective view showing a state in which the object to be stored is placed on the mounting table by the folding piece. First, a paper board is punched out to form a developed body 1 as shown in FIG.
This developed body 1 has an overall rectangular shape, and its upper edge 2
In this case, both the upper half contour line and the lower half contour line have an arc shape that bulges outward, and the upper half protrudes above the upper edge, and the lower half contour line sinks into the inside, resulting in reinforcement lines, etc. Three folded pieces 4 (the number is arbitrary) are arranged in parallel at appropriate intervals. Further, a branch piece 5 projects upward from between the left end folding piece part and the central folding piece part of the upper edge, and a disc 6 is attached to the tip thereof.
A fold line 3' is formed at the connection portion of the branch piece 5 with the disk 6 and the upper edge 2. Next, at a position below this upper edge 2 by a distance corresponding to the height of the storage container A, a folding piece 4 having the same shape as the folding piece 4 at the upper edge is placed approximately in the center of the unfolded body 1. Similarly, three folded pieces 4' are arranged in parallel at appropriate intervals, and the contour line of the upper half of the folded piece 4' is a cut line 7, and two rows of cuts 8 are provided at both ends thereof. The dividing line is a fold line 3''.The boundary between each folded piece 4' and the folded pieces at both ends and the unfolded body 1
are connected to both side edges 9 by perforations 10, and a fan-shaped window hole 11 is provided above the contour line of the upper half of the central folded piece. Further, at the lower end of the unfolded body 1, which is lowered from the approximate center of the unfolded body 1 by a distance equal to the height of the storage object container A, there is a fold-in piece 4' provided at the approximate center, a cut line 7, Broken line 3″,
Notch 8, folding piece 4'' similar to window hole 11 and perforation 10, cutting line 7', fold line 3,
A notch 8', a window 11' and a perforation 10' are formed. Of course, it is also possible to further provide folding pieces, window holes, etc. below this as required. This unfolded body 1 is assembled into a cylindrical shape as shown in FIG. 2 by pasting the glue margins 12 on both side edges 9, and the folded pieces 4' and 4'' at approximately the center and lower end are attached to the fold line 3. '', 3 is folded inward, and a cup-shaped container to be stored is placed thereon, and the folded piece 4 and the disc 6 at the upper edge are similarly folded inward from the fold lines 3, 3.
3' is folded inward to form a lid, and finally a heat-shrinkable transparent sheet 13 made of synthetic resin is wrapped over the entire surface and heated to allow the window holes 11, 11' and the folding pieces 4, 4' to be folded. The resulting side hole 14,
The opening at 14' is covered.

The present invention is constructed as described above and obtains the following effects. First, the manufacturing process is completed by simply punching out a sheet of base paper, assembling it into a cylindrical shape, folding the folding piece inward, placing the object to be stored, and packing, which is extremely simple and reduces costs. Next, from a functional point of view, since the fold line of the folding piece on which the stored object is placed has an arc shape, it is strong against weight and can be placed on even quite heavy objects. The curved surface of the piece creates elasticity, making the opening/closing operation of the lid at the upper edge smoother and improving the sealability. Since the folding piece serving as the mounting table is provided with a notch, as shown in FIG. 4, the lower end periphery of the stored object is clamped and fixed, making it stable, thereby preventing side-to-side deflection. After taking out the upper storage object, the upper cylindrical part can be easily removed by tearing the perforation at its lower end, and the fold-out piece that previously functioned as a mounting platform for the upper storage object can now be removed from the lower tier. It will function as a lid for the object to be stored. Therefore, by opening this folding piece, the lower storage object can be easily taken out. Next, the main body is cylindrical, so it is compact and looks good, and the interior can be seen through openings such as windows, which improves fashionability. It's convenient. As described above, the present invention brings about cost reduction, holds objects securely and is robust, allows easy removal of objects, and has a good appearance. Has excellent effects.
