Description

  The present invention relates to a pouch container for filling a product for refilling in liquid, paste or fluid form such as body soap or shampoo.

  Some pouch containers for filling such liquid goods for refilling can be disposed of in a compact state after use. For example, as shown in FIG. 8, the pouch container 50 shown in FIG. 8 is formed in a bag shape by welding the periphery thereof in a state where two flexible sheets 51 are overlapped, and one side edge. A perforation 52 is formed so that the wide welded portion can be separated as a strip-shaped body B having a predetermined width, and slits 53 having a predetermined length are formed at two locations above and below the portion to be separated as the strip-shaped body B. Is formed.

  Therefore, in this pouch container 50, the upper edge portion is opened by breaking, and after the contents are poured out, as shown by a two-dot chain line in FIG. After the strip-shaped body B is cut off from one side edge of the pouch container 50 which has become, as shown in FIG. 10, the pouch container 50 from which the strip-shaped body B is cut is wound in a roll shape, and the strip-shaped body is cut off at both ends. By inserting it into the slit 53 of the body B, it is discarded while being held in a roll shape.

Japanese Patent No. 375867

  However, in the pouch container 50 as described above, in order to obtain a compact form at the time of disposal, the strip B is separated from the empty pouch container 50, and the pouch container 50 is wound into a roll shape and then rolled. Since the pouch container 50 wound in a shape must be held in a roll shape by inserting it into the slit 53 of the strip-shaped body B cut off from the pouch container 50, the operation of winding the pouch container 50 is performed in a series of operations. There is a problem that the pouch container 50 wound in a roll shape cannot be held in that state, and workability is poor.

  Moreover, in the pouch container 50 as described above, the pouch container 50 must be wound so that the pouch container 50 can be inserted into the slit 53 formed in the belt-like body B. However, the diameter of the pouch container 50 can be inserted into the slit 53. Since it is not immediately known whether it can be done, the diameter of the pouch container 50 wound in a roll shape may be too large. In such a case, the pouch container 50 wound in a roll shape must be once expanded and wound again. In that respect, there is a problem in workability.

  Therefore, an object of the present invention is to provide a pouch container that can be easily held in a compact form at the time of disposal by a series of operations.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a pouch container provided with a container body formed by a flexible sheet including at least a pair of facing exterior sheets, and each side of the container body The pouch container is characterized in that an upper latching portion and a lower latching portion that can be engaged with each other are continuously provided on the edge so as to protrude outward in the width direction.

  According to a second aspect of the present invention, in the pouch container according to the first aspect of the present invention, the lower side edge of the container body to which the lower side hooking portion is connected is a base of the lower side hooking portion. It has the inclination part which inclined inward toward the upper direction from the edge, It is characterized by the above-mentioned.

  As described above, the pouch container of the invention according to claim 1 is in a state in which the upper and lower latching portions that can be engaged with each other on the left and right side edges protrude outward in the width direction. Since the used pouch container is wound up and down in the vertical direction, the upper hook part and the lower hook part are engaged with each other, thereby disposing the pouch container at the time of disposal. Can be held in a wound state.

  In particular, when the used pouch container has been wound, the upper hooking portion and the lower hooking portion are generally opposed to each other, and the upper hooking portion and the lower hooking portion can be continuously engaged with each other. Therefore, the pouch container wound in a roll shape can be held in the discarded state by a series of operations from the operation of winding the pouch container, and the workability is good.

  Further, in this pouch container, regardless of the winding state, the upper latching portion and the lower latching portion are connected to each other regardless of whether they are tightly wound or wound loosely. If the diameter of the pouch container wound in a roll shape is too large, the pouch wound in a roll shape like a conventional pouch container that cannot be inserted into the slit formed in the band-shaped body When the diameter of the container is too large, it is not necessary to perform a troublesome operation such as once expanding the pouch container and rewinding, and the workability is also good in this respect.

  In addition, if the filling amount of the content is about half of the content of the container body, the container body is folded in two up and down, and the upper latching part and the lower latching part are engaged with each other, Even when the pouch container is stored, it can be held in a compact folded state.

  Further, the pouch container of the invention according to claim 2 is such that the lower side edge of the container body to which the lower side latching part is connected is inclined inwardly upward from the base end of the lower side latching part. Spring back force that tends to return to the original when the pouch container is wound easily acts on the lower latching portion, and the upper latching portion and the lower latching portion are mutually connected. When engaged, there is an effect that the engagement strength between the two is increased and the engagement between the two is difficult to be released.

  Hereinafter, embodiments will be described with reference to the drawings. A pouch container 1 shown in FIG. 1 is a large-capacity pouch container for filling liquid goods such as commercial detergents and shampoos for refilling into bottle containers, and is filled with liquid goods, and has a thickness of 60 to 200 μm. A container main body 10 formed of a flexible sheet of a certain degree and a spout 20 attached to the container main body 10 for pouring out liquid goods filled in the container main body 10 are provided.

  The flexible sheet forming the container body 10 is usually composed of a single-layer or multiple-layer resin film, and a multilayer sheet having a base film layer and a sealant layer that imparts heat sealability. When a high gas barrier property is required, it is preferable to provide a gas barrier layer between the base film layer and the sealant layer.

  The film constituting the base film layer is composed of polyester such as polyethylene terephthalate, polyolefin such as polyethylene and polypropylene, polyamide such as nylon-6 and nylon-66, and ethylene-vinyl alcohol copolymer (EVOH). One or two or more layers of stretched or unstretched films can be exemplified.

  As the film constituting the sealant layer, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP) , Biaxially stretched nylon (ON), ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film having one layer or two or more layers can be exemplified.

  As the gas barrier layer, a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC), an ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film (for example, a base film layer) And a film obtained by evaporating (or sputtering) an inorganic oxide such as aluminum, aluminum oxide, or silica.

  As shown in FIGS. 1 and 2 (a) and 2 (b), the container body 10 includes a pair of exterior sheets 11 forming a trunk portion, and bottom gussets that are folded inward from the lower ends of both exterior sheets 11. A bottom gusset sheet 14 that forms a part, and the peripheral edge of the inner surface of the folded bottom gusset sheet 14 is heat-sealed to the lower inner surface of the exterior sheet 11, and both side edges of the inner surface of the exterior sheet 11 are mutually By being heat-sealed, it is formed in a bag shape. In addition, the area | region where the shaded display part in FIG. 1 is heat-sealed is shown.

  The exterior sheet 11 has a substantially rectangular shape, and an upper latching portion 12 and a lower latching portion 13 that can be engaged with each other are stretched outward in the width direction at the upper and lower end portions of the left and right side edges. The both side edges of the bottom gusset sheet 14 that are continuously provided in such a state that are folded inwardly from the lower ends of the two exterior sheets 11 are also the lower side edges of the exterior sheet 11 in which the lower latching sections 13 are continuously provided. Have the same shape.

  The upper hooking portion 12 is formed with a hole 12a into which the tip of the lower hooking portion 13 can be inserted, and the upper hooking portion on the upper and lower edges of the lower hooking portion 13 is formed. A pair of V-shaped notches 13a are formed to engage with the periphery of the hole 12a when inserted into the 12 holes 12a.

  The bottom gusset sheet 14 that is folded inward from the lower end of the exterior sheet 11 also has a latch portion 15 having the same shape as the lower latch portion 13 at a position corresponding to the lower latch portion 13 of the exterior sheet 11. A pair of V-shaped notches 15 a are formed at positions corresponding to the pair of notches 13 a of the lower latching portion 13 at the upper and lower edges of the latching portion 15.

  Further, the lower side edge of the exterior sheet 11 and the side edge of the bottom gusset sheet 14 to which the lower side latching part 13 and the latching part 15 are continuously arranged are the inner side upward from the inner edge of the notch 13a and the notch 15a. The inclined portion 11a and the inclined portion 14a which are inclined to each other. Due to the presence of the inclined portion 11a and the inclined portion 14a, when the pouch container 1 is wound, the springback force which tries to return to the original state is latched on the lower side. When the heat-sealed lower latching portion 13 and the latching portion 15 are inserted into the hole 12a of the upper latching portion 12, a notch on the periphery of the hole 12a is obtained. The engagement strength with respect to 13a and the notch 15a is increased, and there is an effect that the lower latching portion 13 and the latching portion 15 are not easily detached from the hole 12a.

  Further, the latching portions 15 of the bottom gusset sheet 14 are respectively formed with holes 15b that match each other in a folded state, and the lower latching portions of the exterior sheets 11 and 11 are formed through the holes 15b. 13 and 13 are partially heat-sealed.

  As shown in FIGS. 1, 2 (a) and 2 (b), the spout 20 opens and closes a mouth body 21 for pouring out liquid goods filled in the container body 10 and the mouth body 21. The screw cap 22 and a mounting portion 23 having a boat-shaped or elliptical cross-section, which are connected to the mouth portion main body 21, are sandwiched between the upper edges of the pair of exterior sheets 11. It is heat-sealed.

  When the pouch container 1 configured as described above is emptied by refilling the filled liquid commodity into a bottle container or the like, as shown in FIGS. The upper hooking portion 12 is wound upward, the lower hooking portion 13 is inserted into the hole 12a of the upper hooking portion 12, and the notch 13a of the lower hooking portion 13 is engaged with the periphery of the hole 12a of the upper hooking portion 12. By this, the pouch container can be held in a compact winding state that is a form at the time of disposal.

  In particular, when winding of the used pouch container 1 is completed, the upper hooking portion 12 and the lower hooking portion 13 are substantially opposed to each other, and subsequently the lower hooking portion is placed in the hole 12a of the upper hooking portion 12. 13 can be inserted, and the pouch container 1 wound in a roll shape can be held in a discarded state by a series of operations from the operation of winding the container body 10, and the workability is good.

  Moreover, in this pouch container 1, regardless of the winding state, the lower hooking portion 13 is connected to the upper hooking portion 12 regardless of whether the pouch container is tightly wound or loosely wound. So that if the diameter of the rolled pouch container is too large, it can be wound into a roll like a conventional pouch container that cannot be inserted into the slit formed in the belt-like body. When the diameter of the pouch container is too large, it is not necessary to perform the troublesome work of once expanding the pouch container and rewinding it, and the workability is also good in this respect.

  Further, if the filling amount of the contents is about half of the inner volume of the container main body 10, the lower hooking portion 13 is inserted into the hole 12 a of the upper hooking portion 12 with the container main body 10 folded in two up and down. Thus, by engaging the notch 13a of the lower latching portion 13 with the peripheral edge of the hole 12a of the upper latching portion 12, the pouch container can be held in a compact folded state.

  In the pouch container 1 described above, the lower side edge of the exterior sheet 11 and the side edge of the bottom gusset sheet 14 to which the lower side hooking part 13 and the hooking part 15 are connected are arranged inside the notch 13a and the notch 15a. Although it has the inclination part 11a and the inclination part 14a which inclined inward toward the upper direction from the edge, it is not limited to this, Both side edges of 10 A of container main bodies like the pouch container 1A shown in FIG. The shape may extend substantially directly below the lower edge of the upper latching portion 12.

  Further, in the above-described pouch container 1, the upper and lower hooking portions 12 and 13 that can be hooked to each other are disposed at the upper and lower end portions of the left and right side edges. For example, the upper latching portion is arranged in the upper region when the container main body is divided into three vertically, and the lower latching portion is arranged in the lower region when the container main body is divided into three equal parts. It only has to be installed.

  Further, the pouch containers 1 and 1A described above have the spout 20 mounted on the container main bodies 10 and 10A, but the present invention is not limited to this. For example, as shown in FIG. Instead, the spout forming portion 16 is connected to the upper end edge of the container body 10, and the spout M is formed by breaking the spout forming portion 16 as shown in FIG. It goes without saying that the present invention can also be applied to the pouch container 1B.

  Further, in the above-described pouch containers 1, 1A, 1B, when the contents are poured out, the contents can be poured out in a state where the left and right upper latching portions 12 are overlapped and picked up. Good nature. In particular, in the case of the pouch container 1B to which a spout is not mounted, when the contents are poured out, the left and right upper latching portions 12 are overlapped and picked up, as shown in FIG. Since the spout M is formed, it is possible to ensure the same workability as when the spout is attached.

  Moreover, in the above-mentioned pouch container 1B, although the spout formation part 16 is continuously provided in the center part of the width direction in the upper end edge of the container main body 10, it is not limited to this, The pouch container shown in FIG. As in 1C, the spout forming portion 16a can be continuously provided so as to protrude obliquely upward on one side in the width direction at the upper end edge of the container body 10.

  Moreover, in each embodiment mentioned above, although it has tried to engage both by inserting the lower latching part 13 in the hole 12a of the upper latching part 12, it is not limited to this, For example, A hole may be formed in the lower latching portion, and the upper latching portion may be inserted into the hole in the lower latching portion. On one side edge side, a hole is formed in the upper latching portion, and the upper latching portion is formed. The lower latching part may be inserted into the hole of the latching part. On the other side edge side, a hole may be formed in the lower latching part, and the upper latching part may be inserted into the hole of the lower latching part.

  Moreover, in each embodiment mentioned above, although the notch 13a, 15a latched in the hole 12a of the upper latching part 12 is formed in the upper edge and lower edge of the lower latching part 13 and the latching part 15, The notches 13a and 15a can be omitted.

  Moreover, in each embodiment mentioned above, a hole is formed in any one of an upper side latching part and a lower side latching part, and both are latched by inserting the other latching part in the hole. However, the present invention is not limited to this, and it goes without saying that various latching portions can be adopted as long as they can be engaged with each other.

  The present invention can be used when a large-capacity pouch container is discarded in a compact state.
