The present invention relates to an auto bottom type paper box. More specifically, the present invention relates to a display carton for displaying products such as ice cream at a retail store such as a convenience store.

[0002]

2. Description of the Related Art Conventionally, an auto-bottom type paper box has been known as a paper box for selling confectionery or the like and a paper box for displaying products. Auto bottom refers to a paper box composed of a single blank, which is automatically formed at the same time as the bottom of the box is opened when the box is opened from a folded state.

FIG. 1 shows an example of a conventionally known blank constituting an auto bottom type paper box. FIG.
Is the blank 10 viewed from the side forming the outer surface of the box after assembly.
0 is shown. In the blank 100, side wall blank portions 101 to 104, which constitute a paper box peripheral wall after assembly, are connected via folding lines A, B, and C. Side wall blank
An adhesive flap 110 is connected to one side of the base 101 via a crease D, and the adhesive flap 110 is
Glued to the back side of

[0004] Below the side wall blank portions 101 and 103, bottom wall blank portions 106 and 107 are connected via folding lines E and G, respectively. In FIG. 1, the bottom wall blank 106
Is provided on the right side with a diagonal crease I, and the bonding margin 106a is attached to the side wall blank portion 102.
Is adhered to an adhesive flap 111 provided below the fold F via a folding rule F. Similarly, a bonding margin 107a is provided on the right side of the bottom wall blank 107 via a diagonal crease J. The bonding margin 107a is provided below the side wall blank 104 via a crease H. Is bonded to the bonded flap 112.

In each of the bottom wall blank portions 106 and 107, the right half opposite to the bonding margins 106a and 107a greatly extends downward in FIG.
6b and 107b. The function of each overlapping flap will be described later. Further, breakable opening zippers 108 are formed in the side wall blank portions 101 to 104.

The folds I and J are valley folds, all other folds are mountain folds, and the bonding margins 106a and 107a are bonded to bonding flaps 111 and 112, respectively.
FIG. 2 schematically shows a state in which the blank 100 is folded while the “0” is adhered to the back side of the side wall blank portion 104. FIG.
In the above, the bonding margin 106 of the bottom wall blank portions 106 and 107
The illustration of the adhesive flaps 111 and 112 and the zipper 108 adhered to a and 107a is omitted.

From the folded state in FIG. 2, the side wall blank portions 101 and 103 are spread apart from each other, and the bottom wall blank portions 106 and 107 are pushed down. At this time, the overlapping flap 106b of one bottom wall blank portion 106 is located on the upper surface side of the other bottom wall blank portion 107, and similarly,
The overlapping flap 107b of the other bottom wall blank portion 107 is located on the upper surface side of the bottom wall blank portion 106. As a result, the corner portions 106c and 107c (see FIG. 1) provided at the corners of each overlapping flap 106b, 107b are mutually connected. When engaged, the bottom wall of the paper box is automatically configured. This is why it is called auto bottom.

On the other hand, there is a case where a paper box formed of such a blank is used not only for conveying goods but also as a display carton at the time of actual sales. In this case, the goods are actually displayed. In order to prevent the products located on the rear side from being hidden by the products on the near side in the box, a step-shaped or sloped insole is separately assembled and inserted into the box.

However, assembling the stepped or sloped insoles one by one with respect to each of a large number of paper boxes is inferior in workability, and moreover, the assembled insoles are inserted one by one into the paper box. Going is also a tedious task.

[0010]

Accordingly, a technical problem to be solved by the present invention is to separately assemble and insert a special insole formed in an inclined or stepped shape even when used as a display carton. It is to provide an auto bottom type paper box which is unnecessary.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in order to effectively solve the above-mentioned problems.
An object of the present invention is to provide an auto-bottom type paper box in which a bottom wall is inclined. That is, the present invention provides a paper box having the following features.

That is, the paper box of the present invention is composed of one blank, and includes "four side walls forming a rectangular cylindrical peripheral wall" and "a bottom wall blank portion connected to each of a pair of opposed side walls. Bottom wall consisting of "another 1
And an adhesive flap connected to each side wall of the set and bonded to a different bottom wall blank portion. The "each bottom wall blank portion" is connected to the side wall via a substantially right-angled triangular intermediate blank portion which is arranged in the same direction and in the same direction as each other. Each intermediate blank part of the right triangle is
The oblique side is connected to the bottom wall blank portion, and the other side is connected to the side wall. Further, the adhesive flaps connected to the side walls adjacent to the right-angled corner portions of both the intermediate blank portions are separated by a distance equal to the remaining one side of the intermediate blank portions via the intermediate blank portion separating the side walls and the adhesive flap. It is connected to the side wall.

[0013] In the paper box of the present invention having the above configuration, in the blank constituting the paper box, the bottom wall blank portion is connected to the side wall blank portion via a triangular intermediate blank portion. The two intermediate blank portions respectively connected to the side walls of the first and second joints are congruent with each other and face the same direction after the blank is assembled. Therefore, the bottom wall of the paper box formed after blank assembly has a slope defined by the triangular intermediate blank portion. Further, since this triangle is a substantially right triangle, the inclined bottom wall extends without a gap from the front wall to the rear wall of the paper box.

As described above, the paper box of the present invention is of the auto-bottom type, and the automatically formed bottom wall itself is inclined. It is not necessary to separately assemble and insert a special insole configured in a shape of steps or steps. It is needless to say that the paper box of the present invention can be used not only as a display carton but also as a packaging paper box that is sold in a state in which confectionery and the like are stored.

It is preferable that the paper box of the present invention further includes an upper lid provided substantially parallel to the bottom wall, and a rupturable opening zipper is formed over the entire circumference of the peripheral wall. This configuration is particularly advantageous when the paper box is used as a display carton. That is, in the case of employing this configuration, a plurality of products are shipped in a state in which the paper box is stored, a zipper is determined in a retail store such as a convenience store, which is a shipping destination, and each product in the zipper is exposed. Can be displayed together with the paper box. Then, since the bottom wall of the paper box is inclined, when the shopper grabs the product in the foreground, the product on the rear side automatically slides forward. In this case, it is preferable to arrange a sheet-shaped insole with a resin layer coated thereon to improve the slip of the product on the bottom wall.

When the paper box of the present invention is used as a display carton and the product contained therein has a side wall inclined with respect to the bottom surface, such as ice cream in a cup, "the bottom wall of the paper box is It is preferable that the “slope” is equal to the “slope of the side wall of the product”. In this case, if the product is stored in the paper box with the top surface facing the front side of the carton (that is, the shopper side), the top surface of the product will be upright with respect to the installation surface of the display carton. . That is, the top surface of the product on which a picture or the like for sales promotion is printed is more likely to be noticed by the shopper, and the sales promotion effect can be improved.

[0017]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 3 is a plan view showing a blank 200 constituting a display carton 200 ′ (see FIG. 4) according to an embodiment of the present invention. The basic configuration of this blank 200 is the same as the blank 100 of FIG. 1 that constitutes a conventional auto bottom type paper box, except that it has intermediate blank portions 300, 400, and 500.

The intermediate blank portions 300 and 400 are substantially right triangles, and are connected to the side wall blank portions 201 and 203 via folding lines E and G, respectively. Further, they are connected to the bottom wall blank portions 206 and 207 via the folding lines K and L, respectively. Each intermediate blank portion 300, 400 of a substantially right triangle has a hypotenuse corresponding to the fold line K, L, and the right angle corner portions 301, 4
One of the two sides sandwiching 01 corresponds to the folding rules E and G.

As will be described later, in the assembled display carton 200 ', the side wall blank 202 corresponds to the carton front wall and the side wall blank 204 corresponds to the carton rear wall. Parts 300, 40
The right-angled corner portions 301 and 401 of 0 are adjacent to the carton rear wall 204. Then, an adhesive flap 2 is attached to the rear wall (side wall blank portion 204) via a substantially rectangular intermediate blank portion 500.
12 are articulated. By this intermediate blank portion 500, the side wall blank portion 204 and the adhesive flap 212 are separated from each other by a distance equal to the length of the remaining sides M and N of the triangular intermediate blank portions 300 and 400. less than,
The procedure for assembling the blank 200 will be described with emphasis on points different from the conventional one.

With the folds I, J, K, L, and O set to valley folds and all other folds set to mountain folds, bonding margins 206a and 207a are attached.
Are bonded to the bonding flaps 211 and 212, respectively. At this time, since the sides M, N of the triangular intermediate blank portions 300, 400 and the height of the rectangular intermediate blank portion 500 are substantially equal, the adhesive flap 207a and the adhesive flap 212 can be easily bonded. In this state, the blank 200 is folded in the same manner as in the case of the conventional example shown in FIG. 2, and the blank 200 is expanded in a box shape from there. Be composed. However, each bottom wall blank 206, 207 is a triangular intermediate blank 300, 4
Since it is connected to the side wall blanks 201, 203 via 00, the automatically configured bottom wall will have a slope defined by this triangle.

This triangle is a substantially right-angled triangle, and its right-angled corner is disposed adjacent to the side wall blank 204 forming the carton rear wall after assembling. , C, D, and one side N, M of each triangle respectively overlap. Therefore, a large gap does not occur between the inclined bottom wall and the rear wall in the carton.

FIG. 4 shows a perspective view of a display carton 200 'obtained by assembling the blank 200 of FIG.
The display carton 200 'has an upper cover 205 inclined with respect to the carton installation surface, and a bottom wall 220 similarly inclined with respect to the carton installation surface. This bottom wall 220 is shown in FIG.
Are constituted by the bottom wall blank portions 206 and 207 shown in FIG. The top cover 205 and the bottom wall 220 are inclined with respect to the installation surface while keeping substantially parallel to each other.

FIG. 5 shows a state where the upper cover 205 of the display carton 200 'is opened. In this state, a plurality of products such as the ice cream 20 in a container shown in FIG.
Shipped with 5 closed. As described later, the ice cream 20 in the container has a top surface 22a having a front wall 22a.
A large number of them are accommodated in the display carton 200 'in a state of being directed in a direction overlapping with the 202.

The ice cream 20 in the container shown in FIG.
Is formed by wrapping a sales promotion cover 22 around a cup 21 containing ice cream so as to surround it. The sales promotion cover 22 includes a “top surface 22a covering the top surface of the cup 21”, “side walls 22b extending on both sides from the top surface 22a”, and “connection pieces 22c that are folded back to the bottom surface of the cup 21 and connected to each other”. The top surface 22a is printed with a pattern or the like that evokes the consumer's willingness to purchase.

In a retail store such as a convenience store, as shown in FIG.
The opening zipper 208 formed on the peripheral wall is broken, and the stored ice cream is exposed and the whole carton is displayed. In FIG. 7, the broken edge 208a formed after breaking the zipper 208 is drawn smoothly, but actually,
As in the case where a normal zipper is broken, it becomes an edge of rattling.

As can be seen from FIG. 7, the side wall 202 on the side on which the top surface 22a of the ice cream 20 in a container is exposed constitutes the front wall of the display carton 200 '.
Since the zipper 208 is configured to be wide downward in the front wall 202, after the zipper 208 is broken,
A large concave portion 202b is formed on the top surface of the ice cream 20, so that most of the top surface 22a of the ice cream 20 in the container is exposed to the front of the display carton 200 '.

FIG. 8 shows a state in which all of the ice cream 20 in the container is removed from the state of FIG. 7, and explains that the bottom wall of the display carton 200 'is inclined. It can also be seen that the side wall blank 204 constitutes the rear wall of the carton after assembly. As described above, the bottom wall of the display carton 200 'is configured by combining the bottom wall blank portions 206 and 207 in FIG. It is preferable to arrange a sheet-like insole with high smoothness in order to improve the quality. FIGS. 5 and 8 show a state where the insole sheet 221 is placed on the bottom wall 220 shown in FIG. The insole sheet 221 is preferably, for example, one in which a backing sheet is coated with a resin layer or the like to improve smoothness. As the resin layer, for example, an overprint varnish (so-called OP varnish) applied by offset printing is preferable. This is such that a thermoplastic resin, an aqueous resin or the like contains a lubricant mainly composed of silicon.

In FIG. 7, when the shopper grabs the foremost ice cream, the rear group of ice creams slides on the inclined bottom wall and sequentially moves forward.

When the product contained in the display carton 200 'has a side wall inclined with respect to the bottom surface, such as the illustrated ice cream 20 in a container,
As shown in FIG. 9, it is preferable that the inclination angle α ₁ of the bottom wall 220 of the display carton 200 ′ is equal to the inclination angle α ₂ of the side wall of the product. By doing so, the top surface of the product is exactly upright with respect to the installation surface of the display carton 200 ', and the top surface of the product on which the pattern for sales promotion is printed is easily noticed by the shopper, The sales promotion effect can be improved.

From the viewpoint of improving the sales promotion effect, it is preferable that the concave portion 202b formed in the front wall 202 of the display carton 200 'is as large as possible. When this point is emphasized, the blank 200 shown in FIG.
Can be adopted. The difference between this blank 1200 and the blank 200 shown in FIG.
, And other basic configurations are the same. Therefore, the assembly procedure and the method of use are the same.

In the blank 1200 shown in FIG.
A portion 1208a formed on the front wall 1202 of the extension 08 extends to the lower edge of the front wall 1202. Therefore, when the zipper 1202 is broken, the concave portion 202b shown in FIG. 7 extends further downward and reaches the installation surface, and
The exposed area of the top surface 22a of the 20 increases, and the sales promotion effect further increases.

In the above embodiment, the paper box of the present invention has been described as a display carton which is used in a state in which a large number of commodities are packed and shipped and displayed in a retail box along with the paper box. It is needless to say that the paper box can be used not only as such a display carton but also as a packaging paper box or the like purchased by a consumer in a state in which a confectionery or the like is stored.
