Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in a packaging container formed from thick paperboard such as cardboard.

[Conventional technology]

Conventionally, there have been packaging containers of this type as shown in FIGS. 4 to 7 (first conventional packaging container). That is, in the developed view of Fig. 4,
A is a thick paperboard such as cardboard, and is formed by connecting a rectangular left side plate part B, front side plate part C, right side plate part D, rear side plate part E, and connecting tongue F in a row. Further, on the upper edges of the left side plate part B, front side plate part C, right side plate part D, and rear side plate part E, there are provided a left upper lid part G, a front upper lid part H, a right upper lid part I, and a rear upper part. The lid parts J are connected to each other, and the lower edges thereof include a left lower lid part K, a front lower lid part L, a right lower lid part M, and a rear lower lid part N.
are formed by being connected to each other. In addition, in the figure,
O indicates a slit, the dotted line indicates a mountain shape, that is, a folding line that is bent outward, and the dashed line indicates a folding line that is bent into a trough shape.

Therefore, when unassembled, as shown in Figure 5,
Fold back at the bending line at the boundary between the front side plate part C and the right side plate part D, and attach the right side plate part D to the left side plate part B and the front side plate part C.
and the rear side plate part E are overlapped, and a connecting tongue piece is affixed to the back surface of the left edge of the left side plate part B to fix it.

When assembling, as shown in Fig. 5, press the folded cardboard A from the left and right ends, and insert the left side board part B.
The front side plate part C, the right side plate part D, and the rear side plate part E are separated from each other to form a rectangular shape in plan view.

Next, as shown in FIG. 6, after bending the left lower lid part K and the right lower lid part M inwardly, the front lower lid part L and the rear lower lid part N are folded into each other. The container body Q is formed by overlapping and fixing the joint with adhesive tape P.

Therefore, inside the container body Q, there is an object R, such as a circular container filled with ice cream, pudding, etc.
In order to store the After flattening the section, the object R is stored. Next, after bending the left upper lid part G and the right upper lid part I inwardly, the front upper lid part H is placed thereon.
and rear upper lid part J are folded over each other to close the opening of the container body Q, and the seam is joined with adhesive tape P (see FIG. 7).

Further, as another conventional example, there is one shown in FIGS. 8 to 11 (second conventional packaging container).

That is, in the developed view of FIG. 8, A is a thick paperboard, and is formed by connecting a front side plate part C to the lower edge of a rectangular bottom plate part B, and a rear side plate part D and a bottom plate part B to the upper edge thereof. A lid part E and a locking tongue F having the same area are formed by sequentially connecting them.

Moreover, on both sides of the front side plate part C and the rear side plate part D,
A left side plate part G and a right side plate part H are connected to each other, and reinforcing side plate parts I each having a lower height than the front side plate part C are connected to both sides of the bottom plate part B and the lid part E. Form. Then, the lid part E and the reinforcing side plate part I
A perforation J is formed between the folding line and the folding line for easy separation. K is a slit, and other points are the same as in the above embodiment.

As shown in FIG. 9, the assembly is performed by bending the front side plate part C and the rear side plate part D perpendicularly to the bottom plate part B, and folding the left side plate part to the front side plate part C and the rear side plate part D. After G and the right side plate part H are bent inward and brought together, the reinforcing side plate part I is stood upright and attached to the outer surfaces of the left side plate part G and the right side plate part H, thereby forming the container body L. be done.

Therefore, after storing the items to be stored in the container body L, as shown in FIG. Attach the locking tongue F to the
The reinforcing side plate part I of the lid part E is bent downward and attached to the outer surfaces of the left side plate part G and the right side plate part H.

When taking out the stored items in the container body L, as shown in FIG. 11, first peel off the locking tongue F of the lid E from the outside of the front plate C,
By inserting a finger under the locking tongue F and lifting the lid part E upward from its tip, the perforation J between the lid part E and the reinforcing side plate part I is separated, and the lid part E is removed. Open it upwards and take it out.

However, in the first conventional packaging container, since there are many folded parts at the top and bottom of the container body Q, the amount of thick paperboard A used is large. Furthermore, since there are many bent parts and an auxiliary bottom plate T is required to make the bottom of the container body Q flat, the assembly work is complicated, the number of parts is large, and the cost is high. Furthermore,
There is a seam at the top and bottom of the container body Q, and in order to paste the adhesive tape P there, multiple container bodies Q
When stacked, the upper and lower adhesive tapes come into contact with each other and become slippery, and stacking two or three or more layers may cause the load to collapse.

Furthermore, in the second conventional packaging container, the amount of cardboard A used is reduced compared to the first conventional packaging container;
Since the perforation J is cut when taking out the stored items from the container body L, once it is opened, it is not possible to keep the lid E in the closed state by simply inserting the locking tongue F of the lid E. It is impossible to do so, and the container body L cannot be used again. In addition, when a plurality of container bodies L are stacked, there is a risk that the perforations J of the lower container body L may be cut inadvertently due to the heavy pressure, and the contents may fall out.

As a solution to these conventional drawbacks,
There is a die cut box disclosed in Japanese Utility Model Application Publication No. 56-75114.

[Problem that the invention attempts to solve]

However, in the die-cut box disclosed in the above-mentioned Japanese Utility Model Publication No. 56-75114, the narrow side plate part has a pair of separated inner side plate members and an outer side plate part fixed to the outside of the inner side plate members. It is composed of.

The pair of inner side plate members and outer side plate members are only physically fixed by means of fixation at the surface, and the flaps connected to the inner side plate members only function as lids. First, there is a problem in that the reinforcing effect of the side plate cannot be expected from the combination with the outer side plate.

[Means for solving problems]

The present invention was made to solve the above-mentioned conventional problems, and the gist thereof is to connect the side plate parts 3, 5, 7, and 8 to the four circumferences of the bottom plate part, respectively,
Auxiliary side plate parts 9 are connected to both sides of one of the opposing upper and lower side plate parts 3 and 5, respectively, and are fixed to the outer surfaces of the other opposing left and right side plate parts 7 and 8 during assembly. A reinforcing tongue piece 11 is connected to the upper edge or lower edge of the portion 9 to cover the upper edges of the other side plate portions 7 and 8 and bent inward at right angles, and the one opposing side plate portion 3 is connected to a small lid part 4, and a side plate part 5 is connected to a large lid part 6, respectively.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 3. Note that FIG. 1 is a plan view of the packaging container according to the present invention when it is unfolded, FIG. 2 is a perspective view of the packaging container during assembly, and FIG. 3 is a perspective view of the packaging container after assembly is completed.

In the figure, 1 is a thick paperboard such as cardboard, and a front side plate part 3 and a small lid part 4 are sequentially connected to the lower edge of a rectangular bottom plate part 2, and a rear side plate part 5 is connected to the upper edge of the bottom plate part 2. and the large lid part 6 are successively connected.

Further, on both sides of the bottom plate part 2, a left side plate part 7 and a right side plate part 8, which are at the same height as the front side plate part 3, are connected. An auxiliary side plate part 9 having the same height as the front side plate part 3 is connected to the front side plate part 3, and a slit 10 is formed at the boundary between this auxiliary side plate part 9, the left side plate part 7, and the right side plate part 8. A reinforcing tongue piece 11 is connected to the auxiliary side plate part 9 in the direction of the lid parts 4 and 6, respectively,
At the boundary between this reinforcing tongue piece 11 and the lid parts 4 and 6,
A slit 12 is formed. In addition, in the figure, the dashed-dotted line shows a trough shape, that is, a portion that is bent inward.

Therefore, when assembling, as shown in FIG. 2, the front side plate part 3, the rear side plate part 5, the left side plate part 7, and the right side plate part 8 are respectively bent perpendicularly to the bottom plate part 2 so as to stand upright. After that, the auxiliary side plates 9 are bent in opposite directions and brought together, and the auxiliary side plates 9 are attached to the outer surfaces of the left and right side plates 7 and 8, thereby forming the container body 13.

After storing the object 14 in the container body 13, the reinforcing tongue piece 11 connected to the auxiliary side plate 9
are folded horizontally inward toward each other, covering the upper edges of the left and right side plate portions 7 and 8. As a result, the vertical load applied to the small lid part 4 and the large lid part 6 is received by the reinforcing tongue piece 11 having a relatively wide area in the side plate parts 7 and 8, so it is dispersed, and the load applied to the small lid part 4 and the large lid part 6 is distributed. Since it is received by the upper edges of parts 7 and 8, the structural strength is increased.

Next, the small lid part 4 and the large lid part 6 are folded inward from each other and stacked on the reinforcing tongue piece 11 to close the opening of the container body 13, and the seam is sealed with adhesive tape 15. Fix it. The small lid part 4 and the large lid part 6 have different areas so that their joints do not coincide with the joints of the reinforcing tongue piece 11, so that they can be reinforced against loads in the vertical direction. As the size increases, if the front and back are stacked differently, there will be no slippage due to the contact between the adhesive tapes 15.

[Effect of idea]

As mentioned above, the packaging container according to the present invention has side plate parts 3, 5, 7, and 8 connected to the four circumferences of the bottom plate part, respectively,
Auxiliary side plate parts 9 are connected to both sides of one of the opposing upper and lower side plate parts 3 and 5, respectively, and are fixed to the outer surfaces of the other opposing left and right side plate parts 7 and 8 during assembly. A reinforcing tongue piece 11 is connected to the upper edge or lower edge of the portion 9 to cover the upper edges of the other side plate portions 7 and 8 and bent inward at right angles, and the one opposing side plate portion 3 has a small lid part 4 connected to the side plate part 5 and a large lid part 6, respectively, so this container is better than the second one above, which uses the least amount of cardboard among conventional packaging containers of this type. Furthermore, the portion of the locking tongue F of the lid portion B can be reduced.

The two large and small lids are supported from below near both ends by reinforcing tongues having the required area that cover the upper edges of the side plates and are bent inward from each other. The tongue piece is further supported by the upper edge of the side plate part from the bottom to the inside, so it has great structural strength, and when containers are stacked in multiple tiers, the lid part, especially the lid part that cannot be supported by stored items. It can well support the load near both ends of the container, and the containers can be stacked in multiple tiers.

The lid of the container consists of two parts, large and small, and the opening has a reinforcing tongue with the required area bent inward, so the adhesive tape can be peeled off and the lid can be opened once. Even if the container is reused, the container can be reused by assembling both ends of the lid and the reinforcing tongue using a standard method, or by using adhesive tape to keep the lid closed. is possible.

There are various effects.
