  However, when considering further convenience of the paper container such as ease of holding the paper container and pouring of the liquid, the above-described conventional gable-top type paper container is not sufficiently satisfactory. For example, when trying to increase (or decrease) the volume without changing the height of the paper container, it is necessary to increase (or decrease) the width of the body, and the ease of holding changes. Also, if the volume changes and the size of the paper container changes, the size of the spout also changes, so the ease of pouring also changes. That is, the conventional gable-top type paper container described above has a low degree of design freedom when convenience is taken into consideration.

  Therefore, it is desired to develop a gable top type paper container having a high degree of design freedom and high convenience.

The gable top-type paper container according to the embodiment includes a trapezoidal sheet-like bottom, sheet-like first to fourth sides provided integrally and vertically from each side of the bottom, and the bottoms of these four sides A gable roof provided integrally and continuously with the upper side separated from the first side, and a first gable roof provided on one end side of the gable roof provided continuously with the upper side of the first side portion connected to the lower base of the trapezoid of the bottom portion. A second sleeve portion on the other end side of the gable roof provided continuously to the upper side of the second side portion connected to the upper base shorter than the lower bottom of the trapezoid of the bottom portion; 1 sleeve portion and said second sleeve portion and at least one in formed reclosable spout and a possess, the second verge of the second sleeve portion, the first sleeve portion The gable roof eaves are shorter than the first gap, and the gable roof ridge and the eaves are connected to each other from the one end to the other end. It is inclined in the direction of approach.

In the following description, the portion of the container 100 other than the gable roof 6 may be referred to as the trunk portion 110.

  The first to fourth side portions 2, 3, 4, and 5 have substantially the same height in the direction orthogonal to the bottom portion 1 (FIG. 2). The first side 2 connected from the lower base 11 of the trapezoid of the bottom 1 is wider than the second side 3 connected from the upper base 12 of the trapezoid. The first side 2 and the second side 3 are parallel. The third side 4 and the fourth side 5 are non-parallel. In the present embodiment, the third side portion 4 and the fourth side portion 5 have the same width and the same area.

  The bottom portion 1 has an upper base 12 and a lower base 11 which are parallel to each other, and has two inclined sides 13 and 14 which are inclined to connect both ends of the upper base 12 and the lower base 11 respectively. The upper base 12 is shorter than the lower base 11. The two hypotenuses 13 and 14 are both longer than the lower base 11. The hypotenuses 13 and 14 form an acute angle with respect to the lower base 11. The hypotenuses 13 and 14 form an obtuse angle with respect to the upper base 12. In the present embodiment, the hypotenuses 13 and 14 have the same length.

  The bottom portion 1 is obtained by partially overlapping a first portion 1a continuous to the third side portion 4 via the oblique side 13 and a second portion 1b continuous to the fourth side portion 5 via the oblique side 14. is there. The first portion 1 a has a portion 15 that is folded back to the outer surface side on the side away from the hypotenuse 13. Then, near the end of the second portion 1b on the side away from the hypotenuse 14 is overlapped and adhered to the outside of the folded portion 15 of the first portion 1a, as shown in FIGS.

  As shown in FIG. 2, there are folded portions 1 c and 1 d between the first portion 1 a and the second portion 1 b constituting the bottom portion 1. The folded portion 1c continues through the lower end side of the first side portion 2 (corresponding to the lower bottom 11 of the bottom portion 1). The folded portion 1d continues through the lower end side of the second side portion 3 (corresponding to the upper base 12 of the bottom portion 1). These folded portions 1c and 1d are folded inward without being exposed to the outside in a state where the container 100 is assembled, and bonded to the inner surface of the bottom portion 1 (first and second portions 1a and 1b).

  The first to fourth side portions 2, 3, 4, and 5 are vertically extended from the sides 11, 12, 13, and 14 of the bottom portion 1 to the inner surface side of the bottom portion 1. The first to fourth side portions 2, 3, 4, and 5 have upper sides 2 a, 3 a, 4 a, and 5 a that are separated from the bottom portion 1, respectively. These four upper sides 2a, 3a, 4a, 5a form a trapezoid that is congruent and parallel to the bottom 1.

  The gable roof 6 has an elongated strip-shaped ridge 21 extending along a longitudinal direction perpendicular to the upper base 12 and the lower base 11 of the bottom portion 1, and two eaves 22 and 23. One eave 22 coincides with the upper side 4 a of the third side portion 4. The other eave 23 coincides with the upper side 5 a of the fourth side portion 5. In other words, the two eaves 22 and 23 are parallel to the bottom 1. The ridge 21 is inclined in a direction approaching the two eaves 22 and 23 from one end on the first side 2 side toward the other end on the second side 3 side.

  A trapezoidal flat plate-like first roof portion 24 extends between the ridge 21 and one eave 22. A trapezoidal flat plate-like second roof portion 25 is extended between the ridge 21 and the other eave 23. The first and second roof portions 24 and 25 are inclined downward so as to expand from the ridge 21 toward the eaves 22 and 23, respectively. The first and second roof parts 24 and 25 have a line-symmetric congruence shape with the ridge 21 as the center.

  As shown in FIG. 2, the 1st roof part 24 is connected to the 3rd side part 4 via the upper side 4a. The second roof portion 25 is connected to the fourth side portion 5 through the upper side 5a. On the side away from the upper side 4 a of the first roof portion 24, a band-shaped joint portion 21 a along the longitudinal direction of the container 100 is provided. On the side away from the upper side 5 a of the second roof portion 25, a strip-shaped joint portion 21 b is provided along the longitudinal direction of the container 100. These two joint portions 21a and 21b are bonded to form a ridge 21.

  One end side 24a of the first roof portion 24 that connects one end of the ridge 21 and one end of the upper side 4a, and one end side 25a of the second roof portion 25 that connects one end of the ridge 21 and one end of the upper side 5a. These are all the first ribs and form the first sleeve portion 31 together with the upper side 2a of the first side portion 2. In addition, the end 24b on the other end side of the first roof portion 24 that connects the other end of the ridge 21 and the other end of the upper side 4a, and the second roof portion 25 that connects the other end of the ridge 21 and the other end of the upper side 5a. The end sides 25b on the other end side of the second side are all second loose, and form the second sleeve portion 32 together with the upper side 3a of the second side portion 3.

  The ribs 24 b and 25 b of the second sleeve portion 32 are shorter than the ribs 24 a and 25 a of the first sleeve portion 31. Further, the length of the ridge 21 is designed to be longer than the length obtained by adding one rib 24a (25a) of the first sleeve 31 and one rib 24b (25b) of the second sleeve 32. . Thereby, in the state which opened both the 1st spout 7 and the 2nd spout 8 which are mentioned later, the malfunction which the two spouts 7 and 8 are connected can be prevented.

  The first spout 7 is provided in the first sleeve portion 31 continuously to the upper side 2 a of the first side portion 2. The second spout 8 is provided in the second sleeve portion 32 continuously to the upper side 3 a of the second side portion 3. As shown in FIG. 2, the first spout 7 includes an isosceles triangular fold 33 having the longest bottom side 2 a of the first side portion 2, and two folded portions 34 and 35. Further, the second spout 8 includes an isosceles triangle folding part 36 having two upper sides 3a of the second side part 3 being the longest low side, and two folding parts 37 and 38.

  One folded portion 34 of the first spout 7 is a triangle having two short sides 33 a of the folded portion 33 and one end side 24 a of the first roof portion 24, and the other folded portion 34. The part 35 is a triangle having the other short side 33 b of the folding part 33 and the end side 25 a on one end side of the second roof part 25 as two sides. One folded portion 37 of the second pouring spout 8 is a triangle having one short side 36a of the folded portion 36 and the other end side 24b of the first roof portion 24 as two sides. The folded portion 38 is a triangle having two sides of the other short side 36 b of the folded portion 36 and the end side 25 b on the other end side of the second roof portion 25.

  The first spout 7 opens between the ribs 24a and 25a from one end side of the ridge 21, pulls out the folding portion 33 from the first sleeve portion 31, and folds the two folding portions 34 and 35 to the first. It can be opened by pulling it out from one sleeve 31. When closing the first spout 7, the spout 7 (folded portion 33, folded portion 34, and folded portion 35) that protrudes from the first sleeve portion 31 to one end side is pushed in to push one end of the ridge 21. Close. The first spout 7 can be opened and closed by a similar operation.

  The second spout 8 opens between the rib 24b and the rib 25b from the other end side of the ridge 21, pulls out the folding portion 36 from the second sleeve portion 32, and connects the two folding portions 37 and 38 to each other. It can be opened by pulling it out from the second sleeve 32. When closing the second spout 8, the spout 8 (folded portion 36, folded portion 37, and folded portion 38) protruding from the second sleeve portion 32 to the other end side is pushed in to push the ridge 21. Close the other end. The second spout 8 can be opened and closed by a similar operation.

  As described above, according to the gable top-type paper container 100 of the present embodiment, since the two spouts 7 and 8 having different sizes are provided, the degree of freedom in design can be increased and the convenience can be improved.

  The size of the spouts 7 and 8 is related to the ease of pouring the liquid. The smaller the size, the thinner the liquid can be poured, which is convenient, for example, when transferring detergent to another container. In addition, the larger the size, the larger the amount of liquid poured at a time, and the larger amount of liquid can be poured in a short time. For this reason, for example, in the case of the usage method of transferring the liquid to another container, the pour spout 8 on the upper bottom 12 side having a relatively small size can be used, and a large amount of liquid is discharged from the container 100. In the case of the method, the spout 7 on the lower base 11 side having a relatively large size can be used.

  More specifically, the size of the spout 7 is proportional to the length of the lower base 11 of the trapezoid of the bottom 1, and the size of the spout 8 is proportional to the length of the upper bottom 12 of the bottom 1. For this reason, the width | variety of the trunk | drum 110 at the time of grasping the container 100 changes according to the size of these spouts 7 and 8. FIG. In other words, the size of the spouts 7 and 8 is also related to the ease of grasping the container 100.

  When liquid is poured through a relatively large spout 7, a relatively narrow portion of the body 110 (the body on the other spout 8 side) is gripped. On the other hand, when pouring liquid through the relatively small spout 8, a relatively wide portion of the body 110 (the body on the other spout 7 side) is gripped. The ease of grasping depends on the size of the user's hand.

  That is, according to this embodiment, the size of the other spout 8 (7) can be designed to a desired size without being influenced by the size of the one spout 7 (8), so that the ease of grasping the container 100 is maintained. However, the ease of pouring can be satisfied, and the degree of freedom in design can be increased.

  Further, according to the present embodiment, when the volume is changed without changing the height of the container 100, it is possible to cope with it by changing the length of at least one of the lower base 11 or the upper base 12 of the trapezoid of the bottom portion 1. For this reason, the volume of the container 100 can be changed in consideration of the ease of pouring the liquid and the ease of holding the container 100.

  Further, according to the present embodiment, when the containers 100 are displayed side by side, the first side portion 2 on the side where the width of the body portion 110 is wide is placed in front, or the second side on the side where the width of the body portion 110 is narrow. It can be properly used whether the side portion 3 of this is in front. For example, when the content of the container 100 is a beverage, it is better to make the container 100 look larger, so it is better to arrange the first side part 2 having the wider body 110 in front. For example, when the content of the container 100 is a concentrated detergent, it is better to arrange the second side portion 12 with the narrow width of the body portion 110 in front.

  Moreover, according to this embodiment, since the length of the trapezoid hypotenuses 13 and 14 of the bottom part 1 was made longer than the lower base 11, stability when placing the container 100 on a desk etc. can be improved. That is, according to the present embodiment, when the outer surface of the first side portion 2 is pushed or when the outer surface of the second side portion 3 is pushed, the container 100 is pushed in the longitudinal direction, and the container 100 There is no worry of falling in the direction.

  On the other hand, when the third and fourth side portions 4 and 5 are pushed, the corner portions at both ends of the bottom base 11 of the trapezoid of the bottom portion 1 support the container 100 so as to prevent the container 100 from tipping forward in the pressing direction. That is, since the side parts 4 and 5 are non-parallel to each other, for example, a force component acting perpendicularly to the outer surface of the side part 4 acts obliquely without acting perpendicularly to the side part 5. At this time, the component of the force perpendicular to the side portion 4 is directed toward the one end side of the opposite side portion 5, and the corner portion on the side portion 5 side of the lower bottom 11 functions to prevent the tipping over. .

  Furthermore, since the container 100 of this embodiment differs in the size of the two spouts 7 and 8, the width | variety of the trunk | drum 110 of the container 100 differs, and the ridge 21 inclines in parallel with the eaves 22 and 23. FIG. Thus, since the appearance of the container 100 according to the present embodiment is characteristic, identification is easy as compared with a general gable-top type paper container having a square bottom. For this reason, for example, when the container 100 of this embodiment is used as a container for storing a liquid such as a detergent other than a beverage, an effect of preventing accidental ingestion of contents can be expected.

The above-described embodiments are shown as examples, and are not intended to limit the scope of the invention. For example, the ridge 21 is formed in parallel with the bottom 1, and the eaves 22 and 23 are inclined in a direction approaching the eaves 21 from one end on the first side 2 side toward the other end on the second side 3 side. May be. In this case, the first side portion 2 and the second side portion 3 are rectangular, and the third side portion and the fourth side portion are trapezoidal. The embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. Further, the embodiment is included in the scope and gist of the invention, and is included in the invention described in the claims and the equivalent scope thereof.
