Description

[Detailed description of the invention] Industrial application field The present invention is a packaging box that can be opened and closed on the top and both sides connected to the top can be left in a half-open state, especially for packaging foods such as fruits and vegetables. It's about a box for doing things.

Conventional technology Cardboard boxes are used in various fields such as processed foods, fruits and vegetables, other foods, light bulbs, electrical appliances, machinery, ceramics, glass products, miscellaneous goods, textile products, medicines, and cosmetics. It is commonly used in

Cardboard boxes can be roughly divided into 3 types: A type, B type, and C type.
There are different types, and according to JIS Z1507, type A is A-1 as a format for cardboard boxes and fiber boxes.
There are 5 types of type B to A-5, 6 types of B type to B-1 to B-6, and C type to C-1 to C-.
There are three types of classification: type 3. Among these, the A-1 type (all flaps have the same length, outer flaps butt together) has the highest usage rate.

Although it is generally possible to check the contents of a cardboard box by opening the top, there is no box that allows the side view of the contents to be observed without disassembling the box. The same applies to boxes other than cardboard boxes, such as paperboard boxes.

Problems that the invention aims to solve During the product distribution process, it is not only necessary to open the top of the cardboard box and check the contents from above, but also to observe and observe the sides of the product without touching it. Afterwards, you may want to close the top as is.

In particular, when it comes to foods, especially fruits and vegetables that lose their freshness in a short period of time or are easily damaged, such as broccoli, green asparagus, and peaches, it is often necessary to check the freshness and shape of the fruits and vegetables during the distribution process.

However, with conventional cardboard boxes, although it is possible to open the top and check the fruits and vegetables from above, if you want to observe the sides of the fruits or vegetables, you have to pick up the fruits and vegetables and observe them, so you must be careful. Even if they were paid, the fruits and vegetables were damaged and the value of the product was reduced. Additionally, some conventional cardboard boxes that can be disassembled can be opened not only on the top but also on the sides, but when the sides are opened, the box itself disintegrates, making reassembly difficult. Furthermore, there was a risk of damaging the contents during reassembly.

The purpose of this invention is to provide a packaging box that not only allows the contents to be viewed from above by opening the top, but also allows the contents to be viewed from the side without disassembling the box. be.

Means for Solving the Problems The packaging box of the present invention has a bottom surface 1 as the center, and a pair of opposing sides 12, 12 of the bottom surface 1 are bent lines, and the first side surfaces 2, 2 are connected to each other, and further, half-split top surfaces 3, 3 are connected to the outside of the first side surfaces 2, 2 via bending lines 23, 23,
Also, the other pair of opposing sides 14, 1 of the bottom surface 1
4 is a bending line, and second side surfaces 4, 4 are connected to the outside thereof, and further, second side surface folding surfaces 5, 4 are provided outwardly of the second side surfaces 4, 4 via bending lines 45, 5 are arranged in a row, and tongue pieces 6, 6 are provided on each of the short sides 26, 26 of the first side surface 2, and the outer periphery of each tongue piece 6 is A straight side 6a that is a straight line that runs from the base end on the bending line 12 side of the short side 26 in the direction of extension of the bending line 12 and whose length is longer than the length of the short side of the second side surface 4; From the free end of the straight side 6a to the short side 26
The tongue piece 6 is characterized by having a curved side 6b in which the first half up to the proximal end on the side of the bending line 23 is substantially straight, and the second half is substantially arcuate. By adding this, we achieved the above objective.

As the material for constructing the box of the present invention, cardboard is particularly suitable, and other materials such as paperboard and plastic board can also be used.

The boxes of this invention can be used for a variety of purposes, including processed foods, fruits and vegetables, other foods, light bulbs, electrical appliances, machinery, ceramics, glass products, miscellaneous goods, textile products, medicines, and cosmetics. However, it is useful as a packaging box for food products, especially fruits and vegetables such as broccoli, green asparagus, and peaches.

Examples Next, the present invention will be further explained with reference to examples. Cardboard is used as the material for the box.

FIG. 1 is a developed view showing an example of the packaging box of the present invention, and FIG. 2 is a partial view of the main parts thereof.

3 to 6 are a plan view, a bottom view, a front view, and a right side view of the box after assembly, respectively.
The rear view appears the same as the front view, and the left side view appears the same as the right side view.

Figure 7 is a perspective view with only the top surface open, Figure 8
The figure is a perspective view with the top surface open and the side surfaces connected to the top surface open.

First, the arrangement relationship of each surface will be explained with reference to the developed view of FIG.

1 is a bottom surface, and each surface is connected to the bottom surface 1.

2, 2 is the first side surface, and 1 opposite to the bottom surface 1
The pair of sides 12, 12 are arranged in a row on the outside as a bending line.

A bending line 2 is provided on the outside of the first side surfaces 2, 2.
The half-split top surfaces 3, 3 are connected to each other via 3, 23.

Reference numerals 4 and 4 designate second side surfaces, which are connected to the outside of the bottom surface 1 by using a pair of opposing sides 14, 14 as a bend line.

There is a bending line 4 on the outside of the second side surfaces 4, 4.
Second side folding surfaces 5, 5 are connected to each other via 5, 45. The bending lines 45, 45 are double lines in consideration of the thickness of the cardboard.

The bottom surface 1, first side surfaces 2, 2, half-split top surfaces 3, 3, second side surfaces 4, 4, and second side folded surfaces 5, 5 described above constitute a main surface.

In the present invention, tongue pieces 6, 6 are provided extending from the short sides 26, 26 of the first side surface 2, respectively. During assembly, this tongue piece 6 is inserted into the gap formed by overlapping the second side surface 4 and the second side folded surface 5 to make the box three-dimensional.

As shown in a partial view of the main part in FIG. and a curved side 6b extending from the free end of the straight side 6a to the base end on the bending line 23 side of the short side 26.

Here, the length of the straight side 6a is the second side 4
Set the length to be longer than the length of the short side. Further, the curved side 6b is set in a route from the free end of the straight side 6a to the base end of the short side 26 on the side of the bending line 23, with the first half set in a substantially linear shape and the second half set in a substantially circular arc shape. The curved side 6b has a slight bulge near its base end so as to provide some resistance to opening and closing of the first side surface 2 when the box is assembled.

7A is a first overhanging piece provided on both short sides of the half-split top surface 3, and 7B is a first overhanging piece provided on a bending line 45 that is a boundary line between the second side surface 4 and the second side folding surface 5. This is a first insertion groove provided along. By inserting this first overhang piece 7A into the first insertion groove 7B,
The top surfaces 3, 3 of the halves are fixed with their edges abutted against each other.

8A is a second overhanging piece extending to the outer side of the second side folding surface 5, and 8B is a second extending piece extending along the bending line 14 which is the boundary line between the bottom surface 1 and the second side surface 4. This is the second insertion groove provided. By inserting this second overhang piece 8A into the second insertion groove 8B, the second side folding surface 5 is fixed.

Effects Next, the effects of the present invention will be explained in the case of the above embodiment.

Among the folding lines indicated by broken lines in the developed view of Fig. 1, the folding line 45, which is the boundary line between the second side surface 4 and the second side folding surface 5, is bent inward by 180 degrees, and all other lines are bent inward. Bend it 90 degrees.

At this time, the tongue piece 6 is inserted into the gap formed by overlapping the second side surface 4 and the second side folded surface 5, and the second overhang piece 8A is inserted into the second insertion groove 8.
By inserting it into B, the second side folding surface 5 is fixed.

In this state, put fruits and vegetables and other products into the box, and then insert the first overhang piece 7A into the first insertion groove 7B.
By inserting it into the holder, the top surfaces 3, 3 of the halves are fixed with their edges butted against each other, and the packaging is completed.

By opening the half-split top surfaces 3, 3, the contents can be easily checked from above.

Then, in this state, if you hold the half-split top surfaces 3, 3 or the first side surfaces 2, 2 with your hands and widen them further, a tongue piece 6 is formed by the second side surface 4 and the second side folded surface 5. The first side surfaces 2, 2 are in a half-open state, and the first side surfaces 2, 2 are in a half-open state. This sliding is performed at an arbitrary angle until the approximately arc-shaped part of the curved side 6b of the tongue piece 6 is exposed, but it does not advance any further, and the tongue piece 6 comes out of the above-mentioned gap and the box disassembles. There will be no situation. This is because the straight side 6a of the tongue piece 6 contacts the bending line 45, which is the boundary line between the second side surface 4 and the second side folding surface 5, from the inside, and the first side surface 2, This is because it prevents 2 from expanding excessively. The reason why the length of the straight side 6a of the tongue pieces 6, 6 is set longer than the length of the short side of the second side surfaces 4, 4 is to prevent the tongue pieces 6, 6 from slipping out of the above-mentioned gap.

If the first side surfaces 2, 2 in the half-open state are pushed from the outside, the first side surfaces 2, 2 will smoothly return to their original state. In other words, the first side surfaces 2, 2 can be opened and closed with one touch.

Furthermore, if a slight bulge is provided near the base end of the curved side 6b of the tongue piece 6, it will provide some resistance to opening and closing of the first side surface 2 when the box is assembled. One side 2 opens, but now it does not open easily, and the first side 2 opens when storing the product.
There is no risk of it opening unexpectedly.

Effects of the invention In the present invention, a structure consisting of a straight side 6a and a curved side 6b is adopted as the tongue piece 6, and the length of the straight side 6a is set longer than the length of the short side of the second side surface 4. In addition, since the curved side 6b is configured to consist of a substantially linear portion and a substantially arc-shaped portion, the first side surfaces 2, 2 can be switched between a half-open state and a closed state with a single touch. Moreover, by selecting the ratio between the substantially linear portion and the substantially arc-shaped portion of the curved side 6b of the tongue piece 6, the half-opening angle of the first side surfaces 2, 2 can be arbitrarily set.

Therefore, it is not only possible to open the top surfaces 3, 3 of the box of the present invention and check the contents of the product from above;
It is also possible to observe the side of the product without touching it, and the box can be closed immediately after inspection.

Therefore, it is necessary to frequently check the freshness and shape of various products, especially foods, especially fruits and vegetables that lose their freshness in a short period of time or are easily damaged, such as broccoli, green asparagus, and peaches, during the distribution process. The present invention can fully meet these demands.

In addition, even in cases where the products are packed tightly inside the box and the product cannot be removed simply by opening the top surface because the fingers cannot fit in, the box of the present invention allows the first side 2 to be left in a half-open state. This also has the advantage that the product can be easily taken out.
