  As shown in FIGS. 6 and 7, the soft packaging material containers disclosed in Patent Documents 1 to 3 have a handle hole 53 in a part of the container peripheral seal portion 52 formed on the peripheral edge of the container. This is a configuration provided. Here, FIG. 6 is a view showing a conventional soft packaging material container 50, and FIG. 7 is a perspective view showing a part of the handle hole 53 part of FIG. It is a figure which shows a mode when a hand is inserted in the handle hole 53 and the stopper 54 is inclined below. Note that, when the plug 54 is tilted downward, a load F is applied to the outer side of the handle hole 53 in the container outer direction.

  As shown in FIG. 6, the handle hole 53 has a long shape along the vertical direction of the container, and the longitudinal direction is formed along the container side edge shape. Easy to grip. However, in such a soft packaging material container 50, when a load F is applied to the side of the handle hole 53 on the container side edge side when the content liquid is taken out, it is positioned at the upper end or the lower end of the handle hole 53 surrounded by a dotted line in FIG. There is a problem that the load F concentrates on the container peripheral seal portion 52, and as shown in FIG. 7, the portion is cracked and easily cut.

  Since the container peripheral seal portion 52 is a portion to which the body portion film 51 constituting the front and back surfaces is joined, the container peripheral seal portion 52 has high rigidity and excellent load resistance, but is easily cut when the load is concentrated on one point. In particular, in the case of a large container having a heavy content liquid, the load F also increases, so that the above problem becomes more prominent. As described above, the conventional soft packaging material container 50 in which the handle hole 53 is formed in a part of the container peripheral seal portion 52 has room for improvement in the load resistance of the handle portion.

  An object of the present invention is to provide a soft packaging material container capable of improving the load resistance of a handle portion.

  The soft packaging material container according to the present invention is filled with a spout provided in the upper part of the container, a handle part into which a hand can be inserted, and a container peripheral seal part provided in at least a part of the peripheral part of the container. A gripping portion having a longitudinal direction substantially parallel to a container peripheral edge or a container peripheral seal part and spaced apart from the container peripheral edge or the container peripheral seal part. And provided in the content filling section.

  Moreover, it is preferable that the grip part has a convex shape toward the container peripheral edge or the container peripheral seal part on the container peripheral edge or the container peripheral seal part side.

  Moreover, as for a handle part, it is preferable that the edge part by the side of a container periphery or a container periphery seal part has circular arc shape.

  Moreover, it is preferable that the handle part is composed of a plurality of handle element parts into which fingertips can be inserted.

  According to the soft packaging material container according to the present invention, the handle portion has a longitudinal direction that is substantially parallel to the adjacent container peripheral edge or container peripheral seal part, and separated from the container peripheral edge or the container peripheral seal part, Since it is provided in the content filling part, a gap in the non-sealing region is formed between the handle part and the container peripheral edge or container peripheral seal part, and when gripping the container, the container peripheral part of the handle part or the container peripheral seal part side It is possible to disperse the load applied to the side portion by deforming in the direction (thickness direction) in which the gap intersects the front and back surfaces of the container. Therefore, since it can suppress that a load concentrates on the upper end or lower end of a handle part, even when a big load is added to a handle part, the cutting | disconnection of a handle part can be prevented.

  Further, the container peripheral edge or the container peripheral seal part side part of the handle part is convex toward the adjacent container peripheral part or container peripheral seal part, for example, gradually protrudes from the upper and lower end parts of the side part toward the central part. Since the width of the upper and lower ends of the gap formed between the handle part and the container peripheral edge or the container peripheral seal part is widened, the gap functioning as a part of the content filling part. The contents easily enter the interior space. When the flowability of the contents in the gap is improved, the gap is easily expanded and the gripping property of the container is improved, and the gap is easily deformed in the thickness direction, and the load resistance of the handle portion is also improved.

  Moreover, if the container peripheral part of the handle part or the side part on the container peripheral seal part side has an arc shape, the contents circulate along the arc-shaped side part, and the handle part and the container peripheral part or container peripheral seal The distribution of the contents in the gap formed between the parts becomes smoother.

  Further, if the handle portion is constituted by a plurality of handle element portions into which the fingertips can be inserted, the content liquid can further easily enter the gap formed between the handle portion and the container peripheral edge or the container peripheral seal portion, and the handle portion It becomes possible to further improve the dispersibility of the load applied to the.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1, FIG. 3 to FIG. 5 are plan views showing the soft packaging material container 10 in each embodiment in which the shape of the grip portion or the formation position is different, and shows a state before filling the content liquid. In the following, the soft wrapping material container 10 will be described as a standing pouch (bottom gusset bag). A known form such as a flat pouch can be applied, and is not particularly limited. The spout for taking out the contents will be described as being provided at the corner of the upper part of the container. However, the position of the spout is not particularly limited, and the upper end and the side end of the container can be changed as appropriate. Moreover, although the content to be filled is described as a low-viscosity liquid such as a liquid detergent (hereinafter referred to as a content liquid), it may be a high-viscosity liquid, a gel-like body, a solid such as a powder, or the like. .

  As shown in FIG. 1, the soft-wrapping material container 10 is comprised from a pair of trunk | drum film | membrane 11 which comprises the front and back of a container, and the bottom part film 12 folded in the mountain fold toward the upper side of the container. . The bottom film 12 is a member that performs a function of a town called a bottom gusset. The soft packaging material container 10 is formed by integrally joining two body part films 11 and a bottom film 12.

  The pair of body film 11 and bottom film 12 are usually joined by heat sealing, and the bottom film 12 folded back in a mountain fold is inserted into the lower part of the body film 11 that forms two front and back surfaces. In this state, the container peripheral edge is heat-sealed to form the container peripheral seal part 13 and the filling part 14 that is an internal sealed space filled with the content liquid. In addition, when the container shown in FIG. 1 is filled with the content liquid, the body film 11 on the front and back sides are separated, and the bottom film 12 is developed into a boat shape to develop self-supporting properties.

  The body film 11 and the bottom film 12 constituting the soft packaging material container 10 are required to have basic performance as a packaging body such as impact resistance, wear resistance, heat resistance and gas barrier properties. In addition, it is preferable to be made of a material excellent in rigidity and shape retention. Moreover, since each film is normally heat-sealed, it is provided with a sealant layer. Therefore, it is preferable that the film which comprises the trunk | drum part film 11 and the bottom part film 12 is comprised from the laminated | multilayer film provided with the sealant layer and the base film layer. The sealant layers of the respective films are overlapped and bonded so as to be inside the bag.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP), etc.), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), poly A stretched or unstretched film of one layer or two or more layers composed of ether sulfone (PES) and ethylene-vinyl alcohol copolymer (EVOH) can be used.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. The film can be used.

  As a method for laminating the films constituting the base film layer and the sealant layer, known methods such as a dry lamination method and a hot melt lamination method can be used. The laminated film can also be produced by coextrusion using the above resin material.

  When high airtightness is required, the laminated film preferably has a gas barrier layer. As the gas barrier layer, a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC), ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film is coated with an inorganic oxide such as aluminum oxide or silica. A vapor-deposited transparent vapor deposition film or the like can be provided. When the gas barrier layer is provided, the configuration thereof is not particularly limited, and for example, the gas barrier layer can be provided between the base film layer and the sealant layer. As a method for forming these thin films, a known method such as a vapor deposition method or a sputtering method can be applied. An adhesive layer may be provided between the gas barrier layer and the base film layer.

  The body part film 11 can be provided with a printing layer such as a product name, a product image, or a design (not shown) representing the quality of the product on the surface, that is, the front and back surfaces of the soft packaging material container 10. This printed layer is generally provided on the inner surface of the base film layer.

  The soft wrapping material container 10 includes a spout 17 that is a spout composed of a spout 15 and a cap 16 screwed into the spout 15 at at least one corner of the upper part of the container. Moreover, the corner | angular part of the container in which the stopper 17 is attached is cut diagonally. The spout 15 has a cylindrical body portion and a shape having a through-hole inside thereof, and is provided so as to communicate the filling portion 14 with the outside of the container. The spout 15 is provided on the outer peripheral surface of the body portion of the spout 15. The container peripheral seal portion 13 is formed so as to be closely attached. In addition, as a spout which takes out the content, the spout path in which the front-end | tip part and both sides were formed by the container peripheral seal part instead of the plug 17 can also be applied.

  When taking out the content liquid from the plug 17, it is necessary to remove the cap 16 and tilt the opening direction of the through hole of the spout 15 downward. In order to improve the gripability of the container at the time of taking out the content liquid, the soft packaging material container 10 is provided with a handle portion 18 into which a hand can be inserted. Moreover, the handle | steering-wheel part 18 is provided in the side edge on the opposite side to the cap 17 about the width direction of a container from a gripper viewpoint. Therefore, as will be described in detail later, when the container is gripped using the handle portion 18 when the content liquid is taken out or when the container is transported, the load in the container outer direction is applied to the outer side portion of the handle hole 19. Join. Here, the side portion of the handle hole 19 is a portion that coincides with the cut line of the body film 11 that forms the handle hole 19.

  The handle portion 18 includes a handle hole 19 into which a hand can be inserted, and a handle hole peripheral seal portion 20 formed on the periphery of the handle hole 19. As shown in FIG. 1, the handle portion 18 has a substantially trapezoidal shape that extends long along the vertical direction of the container. From the viewpoint of improving the gripping property, the longitudinal direction, that is, the direction in which the length of the handle portion 18 is long. Is provided at a position (filling portion 14) that is substantially parallel to the adjacent container peripheral seal portion 13 and that is separated from the container peripheral seal portion 13.

  Here, the fact that the longitudinal direction of the handle portion 18 is provided substantially parallel to the adjacent container peripheral seal portion 13 means that the longitudinal direction of the handle portion 18 and the adjacent container peripheral seal portion 13 can be regarded as substantially parallel. For example, when the angle formed by the line along the longitudinal direction and the container peripheral seal portion 13 is about several degrees, it means that such a configuration may be included. In addition, since the container peripheral seal part 13 is normally formed with a uniform width over the entire periphery of the container, the longitudinal direction of the handle part 18 is substantially parallel to the adjacent container peripheral part. Even when the width of the container peripheral seal portion 13 is changed, if the longitudinal direction of the handle portion 18 (the handle hole 19) is substantially parallel to the adjacent container peripheral portion, the handle portion 18 is easily gripped and the gripping property is improved. It will be good.

  As described above, the handle hole 19 is a through-hole into which a hand (fingertip) can be inserted when trying to grip the container. As shown in FIG. 1, the handle hole 19 is formed in a part of the body part film 11 spaced from the container peripheral seal part 13 so as to penetrate the film on the front and back surfaces. That is, since the handle hole 19 is formed at a position surrounded by the filling portion 14, it can be considered that the handle hole 19 is formed in a part of the filling portion 14. Moreover, since the longitudinal direction of the handle part 18 needs to follow the shape of the adjacent container periphery, it is formed so that the longitudinal direction of the handle hole 19 may also conform to the shape of the adjacent container periphery.

  The size of the handle hole 19 is preferably set such that, for example, four fingertips other than the thumb can be inserted, and not larger than necessary in order to increase the capacity of the filling portion 14. Further, when the content liquid is taken out, it is assumed that the fingertip touches the upper or lower side of the handle hole 19, so that the side is rounded like an R shape (arc shape). The shape is preferred.

  The handle hole peripheral seal portion 20 is a joint formed by heat-sealing the peripheral edge of the handle hole 19 formed through the body film 11 and prevents leakage of content liquid from the handle hole 19 portion. It has the function to do. In order to prevent the joining end faces of the body part film 11 on the front and back surfaces from coming into direct contact with the fingertips, the handle hole peripheral seal part 20 may be formed leaving a non-seal area at the periphery of the handle hole 19. Further, as shown in FIG. 1, the width of the handle hole peripheral seal portion 20 can be made to be a substantially uniform width along the entire circumference of the handle hole 19. The side of the hole 19 is defined as the inner side, and the opposite side is defined as the outer side. The shape of the side of the handle hole 19 is substantially parallel to the shape of the grip hole 19 (non-sealed region). When the left side of the handle hole 19 is not left, the side part of the handle hole 19 and the inner side part of the handle hole peripheral seal part 20 are matched).

  As described above, the handle portion 18 is formed at a position separated from the container peripheral seal portion 13. Therefore, a gap (hereinafter referred to as a gap 21) is formed between the handle hole peripheral seal portion 20 and the container peripheral seal portion 13 so that the internal space communicates with the filling portion 14 and allows the content liquid to flow therethrough. That is, the handle portion 18 is formed so that the periphery thereof is surrounded by the filling portion 14, and the internal space of the gap 21 functions as a part of the filling portion 14.

  The gap 21 formed between the handle hole peripheral seal portion 20 and the container peripheral seal portion 13 is a non-sealed portion where the body film 11 on the two front and back surfaces is not joined. By providing, the load F applied to the side portion of the handle hole 19 can be received and dispersed by a mechanism described later. The width of the gap 21 (the length between the handle hole peripheral seal portion 20 and the container peripheral seal portion 13) can be adjusted by the position where the handle hole 19 is formed, the width of the handle hole peripheral seal portion 20, and the like. As the width of the gap 21 is larger, the effect of dispersing the load applied to the side portion of the handle hole 19 is enhanced, but it is preferably set to about 5 mm to 20 mm in consideration of the gripping property and the capacity of the filling portion 14.

  A mechanism for distributing the load due to the presence of the gap 21 will be described with reference to FIG. FIG. 2 is a perspective view showing a portion around the handle portion 18 of FIG. 1 cut away. When taking out the content liquid, the tip is inserted into the handle hole 19 of the handle portion 18 and the plug 17 is moved downward. It shows the situation when tilted to As described above, the handle portion 18 is provided on the side edge opposite to the plug 17 in the width direction of the container. Therefore, when the plug 17 is tilted downward, the handle portion 19 has a side portion on the gap 21 side. A load F directed in the container peripheral direction is applied. Naturally, the load F increases as the weight of the content liquid increases.

  As shown in FIG. 2, when a load F is applied to the side portion of the handle hole 19, the gap 21 (specifically, the body film 11 on the two front and back surfaces constituting the gap 21, the internal space of the gap 21). The content liquid etc. which circulates) accepts the load F and easily deforms in the direction intersecting the front and back surfaces of the container (hereinafter referred to as the thickness direction). As described above, the gap 21 is a non-sealed region where the body part films 11 on the front and back surfaces are not joined to each other and the rigidity is low, and deformation in the thickness direction easily occurs. That is, by providing the gap 21, the load F is dispersed in the thickness direction, and the load applied in the container peripheral direction is relatively reduced. Therefore, the concentration of the load on the handle hole peripheral seal portion 20 located at the upper end or the lower end of the handle hole 19 can be suppressed. As described above, the gap 21 has a function of receiving and dispersing the load F. By providing the gap 21, it is possible to improve the load resistance of the handle portion 18.

  As described above, since the internal space of the gap 21 functions as a part of the filling unit 14, the content liquid can circulate. When the content liquid is filled in the internal space of the gap 21, the gap 21 swells and the gripping property is improved, and the load dispersibility is also improved. However, in the shape of the handle portion 18 shown in FIG. 1, since the upper and lower ends of the gap 21 are narrow, the content liquid may not easily enter depending on the type of the content liquid. Therefore, FIG. 3 shows the soft packaging material container 10 in which the shape of the handle portion 18 is changed for the purpose of improving the flowability of the content liquid in the gap 21.

  As shown in FIG. 3, the handle 18 has a convex shape with the side on the gap 21 side toward the adjacent container peripheral edge (container peripheral seal part 13). That is, the width of the gap 21 in the vicinity of the center of the side portion is the same as that in the first embodiment shown in FIG. 1, and the width of the gap 21 gradually increases from the vicinity of the center of the side portion toward the upper and lower ends. Become. With such a shape, the content liquid can easily enter the internal space of the gap 21, the gripping property is improved, and the dispersion region of the load F is widened and easily dispersed in the thickness direction. Load resistance is also improved. More specifically, the outer side portion on the gap 21 side of the handle hole peripheral seal portion 20 may be a shape that gradually protrudes from the upper and lower ends of the side portion toward the center, and may be a trapezoidal shape or the like.

  As shown in FIG. 3, the overall shape of the handle portion 18 is a semicircular shape that swells toward the peripheral edge of the container. That is, in order to improve the flowability of the content liquid in the internal space of the gap 21, the side shape on the gap 21 side may be an arc shape or the like, and the side shape on the opposite side is not particularly limited. In addition, the shape of the handle portion 18 (the handle hole 19) has a shape that extends long along the vertical direction of the container, as in the soft packaging material container 10 of the first embodiment, and the containers whose longitudinal directions are close to each other. It is formed along the periphery.

  As shown in FIG. 4, it can also be set as the handle part 18 comprised from the handle element part 18a of a perfect circle shape. The plurality of handle element portions 18a are provided to be separated from each other, and each have a handle hole 19a and a handle hole peripheral seal portion 20a. Since each handle element part 18a is provided apart from each other, a gap is formed between each handle element part 18a so that the internal solution can flow in the internal space and function as a part of the filling part 14. By forming such a gap (hereinafter referred to as “grip element part gap 22”), the content liquid can easily enter the gap 21.

  As shown in FIG. 4, four handle element portions 18a are provided along the peripheral edge of the adjacent container. That is, in the handle portion 18 composed of the handle element portion 18a, the direction in which the four handle element portions 18a are arranged is the longitudinal direction, and the handle is similar to the soft packaging material container 10 of the first and second embodiments. The longitudinal direction of the part 18 is formed substantially parallel along the adjacent container periphery. The size of the handle hole 19a of the handle element portion 18a is set so that, for example, one finger can be inserted. When gripping this container, four fingers other than the thumb are inserted into each handle hole 19a. The Therefore, since the load applied to the side portion of the handle hole 19a is distributed at four places, the dispersibility of the load can be further improved. Here, the wider the interval between the handle element portions 18a, the larger the width of the handle element portion gap 22 and the easier it is for the content liquid to enter the gap 21, but this interval needs to be set in consideration of gripping properties. .

  In the above description, the handle portion 18 is described as being provided near the center of the container along the vertical direction of the container. However, the handle portion 18 can also be provided at the upper portion of the container as shown in FIG. In this case, considering the ease of holding the container, the container upper end on the side where the handle portion 18 is provided is cut obliquely, and the handle portion 18 has a container peripheral shape whose longitudinal direction is cut obliquely. It is provided so as to be substantially parallel to the adjacent container peripheral seal 13. Moreover, the handle part 18 is provided apart from the container peripheral seal part 13 which adjoins similarly to the soft packaging material container 10 of the said Embodiment 1-3.

  The handle portion 18 can also be provided with a tongue piece portion. The tongue piece is not formed by punching the body film 11 (only by the cut line) to form the handle hole 19, but for example, a part of the cut line forming the peripheral part of the handle hole 19 is a perforation line or the like. It can be formed by providing a crease line portion. When the handle portion 18 is not used, the handle hole 19 is covered with the tongue piece portion, and the handle hole 19 appears when the hand is inserted into the handle hole 19. Further, if the crease line portion is provided on the side of the handle hole 19 on the gap 21 side, the tongue piece portion is located at the portion that comes into contact with the fingertip, so that the hand contacts the film end surface of the handle hole 19. Can be prevented, and the stimulation to the finger can be reduced.

  The soft packaging material container 10 having the above-described configuration can be manufactured, for example, by the following process. First, an elongated body of a laminated film that becomes the body film 11 and the bottom film 12 is prepared by laminating resin films constituting a base film layer, a sealant layer, and the like. Next, the long body of the body film 11 forming the front surface and the back surface is overlapped, and the long body of the bottom film 12 folded back in a mountain fold toward the upper side of the container is inserted in the lower part, and in this state Then, both end portions along the longitudinal direction of the long body and a predetermined portion orthogonal to the longitudinal direction are heat-sealed. Here, the both ends along the longitudinal direction of the long body are positions that become the upper and lower ends of the container, and the predetermined portion that is orthogonal to the longitudinal direction is the position that becomes the container side end.

  Next, the center of the predetermined part container that has been heat-sealed is cut into one container size, and the portion to which the plug 17 is attached is cut obliquely. With the spout 15 of the plug 17 inserted into the edge of the cut portion, the spout 15 is attached to the upper part of the container by heat sealing. Further, in these cutting process and heat sealing process, a heat seal part to be the grip hole peripheral seal part 20 is formed, and the inside of the grip hole peripheral seal part 20 is punched to form the grip hole 19, thereby softening. The packaging material container 10 can be obtained.

  In addition, the content liquid is filled through the spout 15 of the plug 17, or a part of the container peripheral seal part 13 is set as an unsealed part and filled from there. After that, when filled through the spout 15, the cap 16 is attached, and when filled from the unsealed portion at the periphery of the container, the unsealed portion is heat sealed and sealed, thereby filling the soft packaging material container filled with the content liquid 10 can be obtained. When the content liquid is filled, the body film 11 is separated, and the bottom film 12 is developed to develop the self-supporting property of the container.

  As described above, according to the soft packaging material container 10, the longitudinal direction of the handle portion 18 is provided in a position that is substantially parallel to the adjacent container periphery and separated from the container periphery seal part 13 formed on the container periphery. Therefore, when the container is gripped, the load applied to the side portion of the handle hole 19 on the gap 21 side is dispersed by the gap 21 being deformed in the thickness direction of the container, thereby improving the load resistance of the handle portion 18. be able to.

  Further, the outer side portion on the gap 21 side of the handle hole peripheral seal portion 20 has a convex shape toward the adjacent container periphery, and the handle portion 18 includes a plurality of handle element portions 18a. If the handle element portion gap 22 is provided between 18a, the content liquid can easily enter the gap 21 and the dispersibility of the load applied to the handle portion 18 can be further improved.
