Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a paper container according to the present invention as seen from the front side, FIG. 2 is a perspective view showing the same as seen from the back side, and FIG. 3 is a side view. The illustrated paper container C is formed by assembling the blank B having the developed shape shown in FIG.

The blank B is made of a wrapping material mainly composed of a paper layer, and as shown in FIG. 4, the blank B is largely divided into a body forming portion 1 and a bottom forming portion 2 by a horizontal ruled line a near the lower end thereof, and the right end is also formed. The elongate adhesive flap 3 is divided by the vertical ruled line b toward the side. The body forming portion 1 is divided into a central front panel 4 and left and right rear panels 5 and 6 by vertical ruled lines c and d, and the front panel 4 has a width twice that of the rear panels 5 and 6. A vertical ruled line e having a Y shape at the upper end is provided at the center of the lower part. Further, in this embodiment, the front panel 4
The upper end 4a of the back panel 5 and the upper ends 5a and 6a of the rear panels 5 and 6 have the same circular arc shape as the upper end 4a of the front panel 4 when the rear panels 5 and 6 are joined by the adhesive flap 3. ing.

The lower part of the front panel 4 in the bottom forming part 2 is divided into right and left by a vertical ruled line e. Of these, the right part is a triangular folding panel 7 and ruled lines f and g on both oblique sides thereof. It is divided into folding small panels 8 and 9 connected to each other. Further, from the lower end of the folding panel 7 to the right, a ruled line h
Is provided, so that the adhesive portion 9a is defined below the folding small panel 9. Further, a portion on the left side of the vertical ruled line e is a bottom closing panel 10 which is slightly elongated downward.

The left rear panel 5 in the bottom forming portion 2
The lower part is divided into triangular folding panel 11 and folding small panels 12 and 13 connected to ruled lines i and j on both oblique sides thereof, and ruled line k is provided from the lower end of folding panel 11 to the left. As a result, the adhesive portion 13a is defined in the lower portion of the small folded panel 13. Further, the lower part of the right side rear panel 6 in the bottom forming part 2 is a bottom closing panel 14, and is adhered to the lower part of the bottom closing panel 14 by a ruled line h extending from the lower end of the folding panel 7 to the right. 14a is partitioned.

In the blank B shown in FIG. 4, a grip portion 15 formed by protruding a part of the packaging material is provided on the upper left side of the rear panel 5 on the left side. Notches are formed on both sides of the grip portion 15. 16 are formed. Further, from the root of the grip portion 15 in the lateral direction, that is, from one end side where the grip portion 15 is provided to the other end side, at a depth of about 1/2 to 1/3 of the paper layer from the surface of the packaging material. Two half cuts 17 are formed.

To assemble the paper container C shown in FIGS. 1 to 3 from the above blank B, first fold the back panels 5 and 6 with respect to the front panel 4 along vertical ruled lines c and d, respectively.
The outer surface of the adhesive flap 3 and the inner surface of the end portion of the rear panel 5 are attached to each other and sack-attached. Next, the sucked blank B is raised along the ruled lines b to e to form the body portion 18, and the lower portion of the body portion 18 is closed to form the bottom closed portion 19.

When closing the bottom, as shown in FIG. 5, the bottom closing panels 10 and 14 are bent inward along the ruled line a, and the folding panel 7 is moved inward along the ruled line a and the small folding panels 8 and 9 are closed. The folding panels 11 are folded outward along the ruled lines f and g, similarly, the folding panel 11 is folded inside along the ruled line a, and the folding small panels 12 and 13 are folded outward along the ruled lines i and j, respectively. Then, the adhesive portions 9a and 13a on the lower side of the small folded panels 9 and 13 are respectively marked with ruled lines h and
At k, the adhesive line 14a on the lower side of the bottom closing panel 14 is marked with a ruled line h
Then, the bottom closing panel 10 is overlapped with the bottom closing panel 14 by sandwiching the folded back portion, and then bonded by heat sealing.

After the bottom closing portion 19 is formed as described above, after the contents are put in through the upper opening, the upper end 4a of the front panel 4 and the upper ends 5a, 6a of the rear panels 5, 6 are opposed to each other, and near the upper end. The top closed portion 20 is formed by adhering the inner surfaces of the two by heat sealing. As shown in FIGS. 1 to 3, the paper container C thus manufactured has a rectangular lower portion and a body portion 18 that is flattened upward. Further, the upper end has an arcuately rounded shape.

To open the paper container C, the gripping portion 1
Pick 5 and pull it. As a result, the packaging material is torn along the half cut 17 with the same width as the grip portion 15, and the paper container C is opened near the top. After opening, the contents can be easily taken out by gripping the body 18 with a hand so as to widen the upper part.

Incidentally, as in the above embodiment, the gripping portion 1 is provided on the packaging material.
Instead of providing the half cut 17 with a width of 5, the paper layer in the packaging material is such that the tear direction is a synthetic resin film layer having a tearability in one direction from the one end side of the blank B to the other end side. It may be laminated inside. In this case, when the grip 15 is pulled and pulled, the synthetic resin film layer is torn by the width of the grip 15, and as a result, the packaging material is also torn by the same width as the grip 15. The same effect can be obtained by providing a narrow cut tape on the inner surface of the packaging material and between the notches 16 on both sides of the grip portion 15.

[0019]

As described above, the paper container of the present invention has a novel exterior shape in which the lower part is rectangular and the upper part is flattened so that it is visually distinctive, and moreover the front part is flat. Since there is a large space for explaining the product, there is an advantage that a display effect at a store or the like is larger than that of a conventional paper container, and that it greatly contributes to sales promotion.

Further, since the container itself has a hermeticity, it is not necessary to put the contents in an inner bag or to wrap the outer side of the container in a hermetically sealed state as in the conventional case, and the manufacturing is easy.

Further, in the case where the grip portion is provided outside the portion to be sacked, the body portion is torn by the width of the grip portion by pulling the grip portion with one hand even if the body portion is gripped with one hand. The opening operation can be easily performed. Moreover, since the container can be used as a cup after opening, the contents can be directly picked up with fingers and taken out easily without transferring to another container or the like.
