Description

Technical Field

[0001] The present invention relates to a standing pouch that can be made to stand on a placement surface by using a bottom seal as a stand.

Background Art

[0002] Conventionally, there has been provided a standing pouch including a front film, a back film, and a bottom film disposed between the front film and the back film at the bottom of the pouch and heat-sealed to the front film and the back film by a bottom seal, which can be made to stand on a placement surface with the bottom side of the pouch facing down by using the bottom seal as a stand (see, for example, Patent Document 1).

[0003] In a state where such a standing pouch is made to stand, since the contents tend to accumulate on the bottom film side due to gravity, the applicant of the present application has considered providing a pouch that can pour out the contents immediately after opening the spout by attaching a spout to the bottom film by utilizing the characteristics of such a standing pouch.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when a spout is attached to the bottom film, in order to prevent the spout from contacting the mounting surface while the bottom seal acts as a stand to allow the standing pouch to stand on its own, the height of the bottom seal in the vertical direction must be set greater than that of a normal standing pouch, which results in a larger pouch size in the vertical direction. In addition, because the height of the bottom seal in the vertical direction must be set greater than that of a normal standing pouch, the rigidity of the film must be designed to be higher than usual in order to ensure the rigidity of the bottom seal, which reduces the design freedom of the film.

[0006] Therefore, the present invention aims to solve these problems and provide a standing pouch with a simple structure that improves the dispensing of contents while suppressing an increase in size in the vertical direction. [Means for solving the problem]

[0007] The present invention relates to a standing pouch comprising a front film, a back film, a bottom film disposed between the front film and the back film at the bottom of the pouch and heat-sealed to the front film and the back film by a bottom seal, and a spout, wherein the bottom film has a front seal region that is heat-sealed to the front film by the bottom seal, a back seal region that is heat-sealed to the back film by the bottom seal, and a non-seal region that is the area inside the front seal region and the back seal region, the non-seal region having a front outer edge that is the boundary with the front seal region and a back outer edge that is the boundary with the back seal region, and the front outer edge and the back outer edge are Furthermore, when the bottom film is unfolded and viewed in plan, it has a bottom edge located on the outermost side in the front-to-back direction, a first inclined edge extending from the bottom edge toward one of the left-to-right sides, which is a first left-to-right side, and formed to move inward in the front-to-back direction as it approaches the first left-to-right side, and a second inclined edge extending from the bottom edge toward the other of the left-to-right sides, which is a second left-to-right side, and formed to move inward in the front-to-back direction as it approaches the second left-to-right side, and the spout is attached to the bottom film such that the center of its dispensing cylinder is positioned closer to the first left-to-right side than an imaginary line connecting the left-to-right center of the bottom edge on the front outer edge and the left-to-right center of the bottom edge on the back outer edge in the front-to-back direction. Furthermore, the bottom seal has a notch formed in which the lower end of the first left-right side portion is cut out, and when viewed in the front-back direction, the tip of the spout's dispensing cylinder portion is exposed. This solves the aforementioned problem. Another aspect of the present invention is a standing pouch comprising a front film, a back film, a bottom film disposed between the front film and the back film at the bottom of the pouch and heat-sealed to the front film and the back film by a bottom seal, and a spout, wherein the bottom film has a front seal region that is heat-sealed to the front film by the bottom seal, a back seal region that is heat-sealed to the back film by the bottom seal, and a non-seal region which is the area inside the front seal region and the back seal region, and the non-seal region has a front outer edge which is the boundary with the front seal region, The spout has a back outer edge which is the boundary with the back sealing area, and the front outer edge and the back outer edge each have a bottom edge which is the outermost part in the front-to-back direction when the bottom film is unfolded and viewed in plan, and a first inclined edge which extends from the bottom edge toward one of the left-to-right sides, and is formed to move inward in the front-to-back direction as it moves toward the first left-to-right side, and the spout is attached to the bottom film such that the center of its dispensing cylinder is positioned toward the first left-to-right side than an imaginary line connecting the left-to-right center of the bottom edge of the front outer edge and the left-to-right center of the bottom edge of the back outer edge in the front-to-back direction. Furthermore, the bottom seal has a notch formed in which the lower end of the first left-right side portion is cut out, and when viewed in the front-back direction, the tip of the spout's dispensing cylinder portion is exposed. This solves the aforementioned problem. [Effects of the Invention]

[0008] According to the present invention, the spout is attached to the bottom film at a position closer to the first inclined edge, which is formed to move inward in the front-to-back direction as it moves outward in the left-to-right direction, rather than near the bottom edge, which is located at the outermost edge in the front-to-back direction, when the bottom film is unfolded and viewed in plan. This makes it possible to position the spout on the bottom film upwards while the standing pouch is self-supporting with the bottom seal as a stand, and by attaching the spout to the bottom film at a position closer to the first inclined edge, it is possible to tilt the spout in the vertical direction. As a result, with a simple configuration, it is possible to suppress the enlargement of the bottom seal in the vertical direction while improving the dispensing of contents by attaching a spout to the bottom film. Furthermore, by suppressing the enlargement of the bottom seal in the vertical direction, it is possible to suppress the reduction in the design freedom of the film.

[0009] Furthermore, by attaching the spout to a position closer to the first inclined edge of the bottom film, the position of the spout can be controlled to be tilted to the first left-right side. In other words, when the spout is attached to the bottom film so as to extend vertically downward from the bottom film, the spout will take on either a state tilted to the first left-right side or a state tilted to the second left-right side, depending on the degree of bending of the bottom film. However, in the present invention, the position of the spout can be controlled to be tilted to the first left-right side.

[0010] Furthermore, if the outer edges on the front and back sides are formed such that the width of the second inclined edge in the left-right direction is wider than the width of the first inclined edge in the left-right direction, and the center of the bottom edge in the left-right direction is positioned closer to the first left-right side, that is, if the bottom edge is formed closer to the spout, it is possible to reduce the space on the bottom film below the spout when the standing pouch is self-supporting, where contents tend to remain, thereby improving the dispensing of contents.

[0011] Furthermore, if the bottom seal is formed so that the tip of the spout's dispensing cylinder is exposed when viewed from the front or back, the visibility of the tip of the dispensing cylinder can be improved. This makes it easier to perform the so-called leveling operation, which involves removing the contents that have spilled out from the tip of the dispensing cylinder after dispensing, thus improving the efficiency of various operations.

[0013] A standing pouch 10 according to one embodiment of the present invention will be described below with reference to the drawings.

[0014] The standing pouch 10 is for containing viscous liquid contents such as mayonnaise and liquid detergents. As shown in FIG. 1, it includes a front film 20 and a back film 30 arranged to face each other in the front-back direction, a bottom film 40 which is arranged in a double-folded state between the films 20 and 30 at the bottom of the pouch and is heat-sealed to the films 20 and 30 by a bottom seal 13, and a spout 50 which functions as an outlet for the contents.

[0015] As shown in FIG. 1, the standing pouch 10 has a top seal 11 formed by heat-sealing between the films 20 and 30 at the top of the pouch, side seals 12 formed by heat-sealing between the films 20 and 30 at both sides of the pouch, and a bottom seal 13 formed by heat-sealing the films 20, 30 and the bottom film 40 at the bottom of the pouch. Thus, it is formed in a bag shape having a content accommodation part 14 for containing the contents.

[0016] Also, at a predetermined position (for example, position A shown in FIG. 1) on both sides of the pouch in the left-right direction in the region where the bottom seal 13 is formed, a portion (a cut-out portion) where the bottom film 40 is partially removed is formed, and the front film 20 and the back film 30 are heat-sealed. Thereby, separation between the films 20 and 30 at the above-mentioned predetermined position (for example, position A shown in FIG. 1) is prevented, and the bottom seal 13 functions as a stand for making the standing pouch 10 stand on the placement surface with the bottom side of the pouch facing downwards. For the sake of illustration, in FIGS. 3 to 6, the portion where the above-mentioned bottom film 40 is partially removed is not shown. When the bottom seal 13 is used as a stand and the standing pouch 10 is made to stand on the placement surface with the bottom side of the pouch facing downwards, the lower edge of the bottom seal 13 contacts the placement surface, and the standing pouch 10 is configured (the dimensions of each part are determined) such that the spout 50 does not contact the placement surface.

[0017] As shown in FIG. 3, the bottom film 40 has a front seal area 41 that is thermally welded to the front film 20 at the bottom seal 13, a back seal area 42 that is thermally welded to the back film 30 at the bottom seal 13, and a non-seal area 43 that is inside the front seal area 41 and the back seal area 42 and is not welded to the films 20 and 30.

[0018] As shown in FIG. 3, the non-seal area 43 has a front outer edge 44 that is the boundary with the front seal area 41 and a back outer edge 45 that is the boundary with the back seal area 42.

[0019] As shown in FIGS. 1 and 3, when the bottom film 40 is unfolded and viewed in plan view, the front outer edge 44 has a bottom edge portion 44a that is located at the outermost in the front-back direction among the front outer edges 44 (is located at the lowermost in the state where the standing pouch 10 is made self-standing with the bottom seal 13 as a stand) (is dot-shaped in this embodiment), a first inclined edge portion 44b that extends from the bottom edge portion 44a toward the first left-right side portion that is one of the side portions in the left-right direction and is formed so as to approach the inside in the front-back direction as it goes toward the first left-right side portion when the bottom film 40 is unfolded and viewed in plan view (approaches upward as it goes toward the first left-right side portion in the state where the standing pouch 10 is made self-standing), and a second inclined edge portion 44c that extends from the bottom edge portion 44a toward the second left-right side portion that is the other of the side portions in the left-right direction and is formed so as to approach the inside in the front-back direction as it goes toward the second left-right side portion when the bottom film 40 is unfolded and viewed in plan view (approaches upward as it goes toward the second left-right side portion in the state where the standing pouch 10 is made self-standing).

[0020] Similarly, as shown in Figures 1 and 3, the back outer edge 45 has a bottom edge portion 45a (point-shaped in this embodiment) that is located on the outermost side of the back outer edge 45 in the front-to-back direction when the bottom film 40 is unfolded and viewed from above (located at the bottom when the standing pouch 10 is standing upright), a first inclined edge portion 45b that extends from the bottom edge portion 44a toward the first left-to-right side and is formed to move inward in the front-to-back direction as it approaches the first left-to-right side when the bottom film 40 is unfolded and viewed from above (moves upward as it approaches the first left-to-right side when the standing pouch 10 is standing upright), and a second inclined edge portion 45c that extends from the bottom edge portion 45a toward the second left-to-right side and is formed to move inward in the front-to-back direction as it approaches the second left-to-right side when the bottom film 40 is unfolded and viewed from above (moves upward as it approaches the second left-to-right side when the standing pouch 10 is standing upright).

[0021] As shown in Figures 1 and 3, both the front outer edge 44 and the back outer edge 45 are formed such that the width of the second inclined edge portions 44c and 45c in the left-right direction is wider than the width of the first inclined edge portions 44b and 45b in the left-right direction, with the left-right center of the bottom edge portions 44a and 45a positioned closer to the first left-right side portion. Furthermore, the first inclined edges 44b, 45b and the second inclined edges 44c, 45c are formed in a curved linear shape that curves outward in the front-to-back direction when the bottom film 40 is unfolded and viewed from above (when the standing pouch 10 is standing upright and viewed in the front-to-back direction, it curves downward).

[0022] Furthermore, in this embodiment, as shown in Figure 3, the bottom film 40 has a valley fold portion 40a formed therein for folding the bottom film 40 in a fold-over state, and this valley fold portion 40a is formed to extend along the left-right direction in the center of the bottom film 40 in the front-back direction. Naturally, after the spout 50 is attached to the bottom film 40, the bottom film 40 will not be folded at the valley fold portion 40a in the vicinity where the spout 50 is attached.

[0023] Furthermore, as shown in Figure 1, the bottom seal 13 is formed such that the tip 51a of the spout 50's dispensing cylinder portion 51 is exposed when viewed in the front-to-back direction. Specifically, the bottom seal 13 has a notch 13a formed on the first left-to-right side portion, where its lower end is cut out, so that the tip 51a of the dispensing cylinder portion 51 is exposed when viewed in the front-to-back direction.

[0024] The spout 50 is made of synthetic resin such as PE or PP, and as shown in Figures 1 and 3, it has a cylindrical dispensing tube portion 51, a flange portion 52 that extends outward from one end of the dispensing tube portion 51, and a cap portion 53 that is detachably attached to the other end of the dispensing tube portion 51.

[0025] In this embodiment, as shown in Figures 1 and 3, the flange portion 52 is formed in the shape of a disc with a through hole in its center, is placed inside the pouch, and is heat-sealed to the inner surface of the bottom film 40 (the surface on the side of the contents storage portion 14). Furthermore, when viewed in the axial direction of the dispensing cylinder portion 51, the spout 50 is formed such that the dispensing cylinder portion 51 is located in the center of the flange portion 52 (the center of the dispensing cylinder portion 51 and the center of the flange portion 52 coincide).

[0026] As shown in Figure 3, the spout 50 is attached to the bottom film 40 such that the center of its dispensing cylinder portion 51 (the center of the dispensing hole when viewed in the extending direction of the dispensing hole of the dispensing cylinder portion 51) is positioned closer to the first left-right side than the imaginary line L connecting the left-right center of the bottom edge portion 44a of the front outer edge 44 and the left-right center of the bottom edge portion 44a of the front outer edge 44 in the front-back direction. More specifically, in this embodiment, the spout 50 is attached to the bottom film 40 such that the entire dispensing cylinder portion 51 is positioned closer to the first left-right side than the imaginary line L, as shown in Figure 3. More specifically, in this embodiment, the spout 50 is attached to the bottom film 40 such that the entire flange portion 52 is positioned closer to the first left-right side than the imaginary line L, as shown in Figure 3. Attaching the entire flange portion 52 to the bottom film 40 in this manner, closer to the first left-right side than the imaginary line L (a position away from the imaginary line L), is preferable because it suppresses the occurrence of unintended wrinkles in the bottom seal 13. That is, when the contents are placed in the contents storage section 14 and the bottom seal 13 is used as a stand to make the standing pouch 10 self-supporting, the portion of the bottom film 40 near the imaginary line L becomes a convex (mountain-shaped) curved portion when viewed in the front-back direction. Therefore, by attaching the flange portion 52 to a relatively flat portion of the bottom film 40, avoiding the area near the imaginary line L, it is possible to suppress the occurrence of unintended wrinkles in the bottom seal 13.

[0027] Furthermore, as described above, the spout 50 is attached to the bottom film 40 at a position closer to the first left-right side than the imaginary line L. In other words, when the contents are placed in the contents storage section 14 and the bottom seal 13 is used as a stand to allow the standing pouch 10 to stand upright on the mounting surface with the bottom of the pouch facing downwards, the spout 50 (at least a part of it, in this example the whole) is attached to the portion of the bottom film 40 that, when viewed in the front-back direction, slopes upward as it approaches the first left-right side. Therefore, when the standing pouch 10 is standing upright, as shown in Figure 1, when viewed in the front-back direction, the axis of the spout 50 (dispensing cylinder 51) is tilted relative to the vertical direction, or in other words, it extends diagonally with respect to the vertical direction (and left-right direction).

[0028] In this embodiment, as shown in Figure 3, the front outer edge 44 and the back outer edge 45 are formed symmetrically with respect to a virtual line (valley fold portion 40a) extending in the left-right direction. Since the left-right center of the bottom edge portion 44a of the front outer edge 44 and the left-right center of the bottom edge portion 45a of the back outer edge 45 are formed at the same position in the left-right direction, the virtual line L extends parallel to the front-back direction. More specifically, in this embodiment, the entire bottom film 40 is formed symmetrically with respect to a virtual line (valley fold portion 40a) extending in the left-right direction.

[0029] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and it is possible to make various design changes without departing from the present invention as described in the claims, such as constructing a standing pouch 10 by arbitrarily combining the configurations of the above or below embodiments or modified examples.

[0030] For example, regarding the specific embodiments of each film 20, 30, and 40, as long as they have a heat-weldable layer on at least one side, such as an olefin-based layer of low-density polyethylene or polypropylene, or a polyester-based layer such as PET (polyethylene terephthalate), a single heat-weldable layer or any layer laminated on the heat-weldable layer may be used. The materials constituting the laminate can be anything, and can be arbitrarily formed by laminating known polyesters such as PET and PBT (polybutylene terephthalate), polypropylene, polyamide, polyethylene, aluminum foil, etc. Furthermore, in the embodiments described above, the bottom film 40, which serves as a gusset film (film for the gusset), was described as being arranged only at the bottom of the pouch. However, the specific form of the standing pouch 10 is not limited to this. For example, a gusset film may also be arranged between the films 20 and 30 at the top of the pouch. In other words, a gusset may also be formed at the top of the pouch. Furthermore, although the above-described embodiment was explained assuming that the front film 20 and the back film 30 are formed separately, the front film 20 and the back film 30 may be formed integrally (formed as a single film), in which case the top seal 11 does not need to be formed.

[0031] Furthermore, in the embodiments described above, the bottom edges 44a and 45a of the non-sealed region 43 were described as being formed as points located at the outermost (lowest) end of the outer edges 44 and 45 in the front-to-back direction, as shown in Figures 1 and 3. However, at least one of the bottom edges 44a and 45a may be formed as a portion extending linearly in the left-to-right direction, as shown in Figure 4. In the case where the bottom edges 44a and 45a are formed as portions extending linearly, as in the example shown in Figure 4, it is preferable to attach the spout 50 to the bottom film 40 such that the entire flange portion 52 is positioned closer to the first left-to-right side than the imaginary line connecting the end of the bottom edge 44a on the first inclined edge 44b side and the end of the bottom edge 45a on the first inclined edge 45b side in the front-to-back direction. Furthermore, in the embodiments described above, as shown in Figure 3, the front outer edge 44 and the back outer edge 45 were described as being formed symmetrically (symmetrically in the front-back direction) with respect to a virtual line (valley fold 40a) extending in the left-right direction. However, the front outer edge 44 and the back outer edge 45 may be formed asymmetrically (asymmetrically in the front-back direction). For example, as shown in Figure 5, the left-right center of the bottom edge 44a of the front outer edge 44 and the left-right center of the bottom edge 45a of the back outer edge 45 may be offset in the left-right direction. In this case, the virtual line L will extend diagonally with respect to the front-back direction. Furthermore, in the embodiments described above, the inclined edges 44b, 44c, 45b, and 45c of the non-sealed region 43 were described as being formed in a curved linear shape that is curved so as to be recessed outward in the front-back direction when the bottom film 40 is unfolded and viewed from above (recessed downward when viewed in the front-back direction with the standing pouch 10 standing upright). However, the specific form of the inclined edges 44b, 44c, 45b, and 45c is not limited to this, and at least one of the inclined edges 44b, 44c, 45b, and 45c may be arbitrarily configured with any curve, straight line, or combination thereof. Furthermore, in the embodiments described above, the outer edges 44 and 45 were described as being formed such that the left-right width of the second inclined edge portions 44c and 45c is wider than the left-right width of the first inclined edge portions 44b and 45b, with the left-right center of the bottom edges 44a and 45a positioned closer to the first left-right side, as shown in Figure 3. However, as shown in Figure 7, the left-right center of the bottom edges 44a and 45a may be formed at a position not closer to either the first left-right side or the second left-right side (the left-right center of the pouch) so that the left-right width of the first inclined edge portions 44b and 45b is the same as the left-right width of the second inclined edge portions 44c and 45c. Alternatively, the left-right center of the bottom edges 44a and 45a may be formed closer to the second left-right side so that the left-right width of the second inclined edge portions 44c and 45c is narrower than the left-right width of the first inclined edge portions 44b and 45b.

[0032] Furthermore, in the embodiments described above, the flange portion 52 of the spout 50 was described as being located inside the pouch and heat-welded to the inner surface of the bottom film 40. However, the manner in which the flange portion 52 is attached to the bottom film 40 is not limited to this. For example, the flange portion 52 may be heat-welded to the outer surface of the bottom film 40 on the outside of the pouch, or the flange portion 52 may be attached to the bottom film 40 by methods other than heat welding, such as adhesive bonding. Furthermore, in the above-described embodiment, the flange portion 52 of the spout 50 was described as being formed in a disc shape with a through hole in its center. However, the specific form of the flange portion 52 is not limited to this and can be any form. For example, the flange portion 52 may be formed with an elliptical or rectangular outer edge. Furthermore, in the embodiments described above, as shown in Figure 3, the flange portion 52 of the spout 50 was described as being located in the center of the bottom film 40 in the front-back direction. However, as shown in Figure 6, the flange portion 52 may be attached to a position offset from the center of the bottom film 40 in the front-back direction, either in the front-back direction or in the back-back direction.

[0033] Furthermore, in the embodiments described above, the front outer edge 44 and the back outer edge 45 were described as having bottom edges 44a, 45a, first inclined edges 44b, 45b, and second inclined edges 44c, 45c. However, as shown in Figure 8, at least one of the front outer edge 44 and the back outer edge 45 does not need to have the second inclined edges 44c, 45c. In the example shown in Figure 8, both the front outer edge 44 and the back outer edge 45 do not have second inclined edges 44c and 45c. In addition to the bottom edges 44a and 45a and the first inclined edges 44b and 45b described above, when the bottom film 40 is unfolded and viewed in plan, it has edges 44d and 45d that extend from the bottom edges 44a and 45a along the front-back direction. In the example shown in Figure 8, similar to the embodiment described above, the spout 50 is attached to the bottom film 40 such that the center of its dispensing cylinder portion 51 is positioned closer to the first left-right side than the imaginary line L (more specifically, the entire dispensing cylinder portion 51 is positioned closer to the first left-right side than the imaginary line L, and more specifically, the entire flange portion 52 is positioned closer to the first left-right side than the imaginary line L). In other words, with the contents placed in the contents storage portion 14 and the bottom seal 13 used as a stand to support the standing pouch 10 on the mounting surface with the bottom of the pouch facing downwards, the spout 50 (at least a part of it, in this example the whole) is attached to the portion of the bottom film 40 that, when viewed in the front-back direction, slopes upward as it approaches the first left-right side.

[0034] As an alternative, the standing pouch 10 may be equipped with a zipper at the top. The zippered pouch can be resealed and can securely seal the contents. The zipper, although not shown, has tape-like male and female parts that can be interlocked. The zipper is sandwiched between film materials, and the zipper is sealed to each film material. As an alternative modification, the pouch may be provided with a hanging hole. Although not shown in the diagram, the hanging hole can be used to hang the pouch from a stand or the like when arranging the standing pouch 10 on a display shelf, or when opening the zipper and storing the contents.

[0035] Furthermore, in the above-described embodiment, the bottom seal 13 is used as a stand to support the standing pouch 10 on the mounting surface, and the lower edge 13b of the bottom seal 13 is formed such that the standing pouch 10 stands upright, or in other words, the vertical direction of the standing pouch 10 (the direction in which the side seal 12 extends) coincides with the vertical direction (specifically, the portion of the lower edge 13b of the bottom seal 13 that contacts the mounting surface is formed along the left-right direction). However, as shown in the modified example in Figure 9, the bottom seal 13 may be formed such that the standing pouch 10 stands upright on the mounting surface using the bottom seal 13 as a stand, or in other words, the lower edge 13b of the bottom seal 13 is formed such that the vertical direction of the standing pouch 10 (the direction in which the side seal 12 extends) is tilted toward the second left-right side (right side in Figure 9) opposite to the side to which the spout 50 is attached (specifically, the portion of the lower edge 13b of the bottom seal 13 that contacts the mounting surface is formed at an angle with respect to the left-right and up-down directions). By forming the lower edge 13b of the bottom seal 13 in this way, when the standing pouch 10 is lifted while standing upright on the mounting surface, the position where the user grasps the standing pouch 10 can be guided to a position diagonally opposite to the spout 50 mounting position (i.e., on the pouch top side and the second left-right side side), which is an appropriate place to apply pressure to the contents inside the contents storage section 14 by the user's grip when squeezing out the contents.
