Description

  The present invention relates to a refill container for storing toiletries such as liquid detergents and softeners, foods such as edible oil and instant coffee.

  Toiletries such as liquid detergents and softeners, and foods such as edible oil and instant coffee are stored in dedicated containers that are easy to use. The dedicated container has a solid structure and is therefore expensive, so a product with a refill container that refills only the contents is sold separately so that it can be used repeatedly when the contents are gone. It is often done.

  For example, liquid detergent containers need to be weighed and taken out each time they are used, so a rigid plastic container with a nozzle at the spout is repeatedly used so that it can be easily poured into a lightweight cup. Used as a container. In contrast to this container, as a refilling container for replenishing the contents, a flexible container made of a flexible packaging film, a container in which a spout is formed, or a container attached with a stopper is generally used. ing.

  A rigid container that is used repeatedly is designed so that it can be easily poured out.Therefore, in consideration of the convenience of the refilling operation of refilling the contents from the refilling container, There wasn't.

  On the other hand, the refill container is not always considering the convenience of the refilling operation because the emphasis is on manufacturing at low cost.

  The refill container can be opened using the nozzle provided in the container to be used repeatedly, and since the refill container is self-supporting during refilling, it does not need to be held by hand. Containers have been proposed. This hand-held refillable container is a refillable container including a coupling member that is detachably connected to an opening of a reusable container and cannot be dropped off, and a container sealing member that seals the refillable container body (see Patent Document 1).

  The refill container described in Patent Document 1 uses two members, namely a coupling member and a container sealing member, in the cap portion in order to combine the reusable container and the refill container, so that the cost of the container is high. It must be. In addition, since the refill container is used by repeatedly screwing it into the opening of the container to be used, the connection between the two is reliable, but on the other hand, it is not only troublesome to operate but also disadvantageous in terms of the cost of the plug. There was a drawback of being.

  From the viewpoint of cost, a packaging bag in which the peripheral edges of two front and back packaging films as shown in FIG. 7 are sealed is advantageous. This refill packaging bag can be provided with a spout having an arbitrary width corresponding to the caliber of the container. However, when the spout is formed by sealing the edges of the two front and back films, When the liquid is poured out, the opening is pulled at both ends sealed, the front and back films are in a pseudo-adherent state, and the spout is blocked.

  In order to solve the problem that the spout is blocked, a part other than the film is inserted into the spout (see Patent Document 2), or the film near the spout is inflated into a three-dimensional shape. Many proposals have been made to secure the opening area.

As a means for solving the above problems, the invention described in claim 1 is a refill container comprising a laminate having at least a base material and a sealant layer, and has a main body surface laminate and a main body back laminate. The sealant layers are opposed to each other, and the periphery is sealed. A single laminate is folded along a fold line with the sealant layer inside, and the folded portion, the main body surface laminate, and the main body back surface are folded. A laminated body is formed, and the bent portion, together with the spout seal portion, forms a spout nozzle for pouring the contents, and the tip of the spout nozzle is a notch provided in the extraction port seal portion. or spout is formed by disconnecting along opening scheduled lines provided to extend from the score line, the bent portion is the folding lines formed by a plurality of scratches one or more layers of substrate layer Width X in a direction perpendicular thereto as heart, 1.0mm ≦ X / 2mm ≦ 20.0mm rough surface portion is provided with, the height of the extraction port, is wider than the width of the rough surface portion The refill container is characterized.

  In order to solve this problem, there has been proposed a packaging bag in which a film constituting the packaging bag is bent to form one side of the spout and the sealing portion of the spout is only one side (see Patent Documents 3 and 4). ). In these packaging bags, the problem that the spout is blocked and the problem that the opening area of the spout is insufficient is solved.

JP 2004-99082 A Japanese Patent Laid-Open No. 5-132069 Japanese Patent Laid-Open No. 11-236053 JP 2008-18991

  In the case of a packaging bag composed of a film in which one side of the spout is folded as shown in Patent Documents 3 and 4, the spout is opened from the seal portion side, but from the seal portion side. The cracks of the starting film do not always coincide with each other at the bent portion, and if they are displaced even a little, the end of the spout is connected, causing a problem that the spout is not completely opened. If this is forcibly pulled, the opening is extended, the cross-sectional area is reduced, and the pouring property is significantly reduced.

  The problem to be solved by the present invention is to propose a refill container that can easily and reliably form a spout without using a spigot, and that can be refilled easily, quickly and reliably. .

The invention according to claim 5 is the refill container according to any one of claims 1 to 4 , wherein a part of the bent portion is cut open to form a content filling opening. is there.

  The refill container according to the present invention is a refill container comprising a laminate having at least a base material and a sealant layer, and has a main body surface laminate and a main body back laminate, with each sealant layer facing each other, Since the periphery is sealed, unlike a plastic bottle or a container using a plastic spigot, it can be manufactured only from the flexible packaging laminate, so that it can be manufactured at low cost.

  In the refill container according to the present invention, a single laminate is folded with the sealant layer inside to form a folded portion, the main body surface laminated body, and the main body back surface laminated body. Since the pouring nozzle for pouring out the contents is formed together with the outlet seal part, it is possible to stably secure a large-area straight outflow passage, and as a result, smooth and quick refilling operation is possible. became.

  In addition, since the bent portion is provided with a rough surface portion formed by a plurality of scratches on one or more base material layers, the cut on the front and back surfaces starting from the spout seal portion at the time of opening is poured out. Even if it does not coincide when it goes around the nozzle and reaches the bent portion, the laminated body is easily cut, so that the spout can be formed stably. On the contrary, it is possible to easily cut from the bent portion side.

The rough surface portion, the width X in the direction perpendicular thereto about said fold line, because it is 1.0mm ≦ X / 2mm ≦ 20.0mm, openability and pouring properties becomes particularly good.

  Further, in the invention described in claim 2, the main body surface laminate, the main body back laminate, and the bottom tape are provided, the respective sealant layers are opposed to each other, and the periphery is sealed. Since the bottom tape is a so-called standing pouch that forms the bottom of the container by forming a bottom seal part with the main body surface laminate and the other end with the main body back laminate. It becomes possible to make a refill container with a capacity.

  In addition, when a handle having a shape that fits in the punching portion is provided on the side opposite to the punching portion of the spout sealing portion that forms the pouring nozzle, the refilling operation can be performed with the grip. Therefore, the refilling operation can be performed safely and easily. Further, since the handle has a shape that fits in the punching portion, the film is not wasted when manufactured by punching from a continuous film.

When the planned opening line is a half-cut line provided on the outer surface of the main body surface laminate and / or the main body back laminate, the spout can be easily opened by tearing by hand. .

  In addition, when a part of the bent portion is cut open to form an opening for filling the contents, even if the container has a shape such that the other sealing portion cannot be used as the filling opening, stable filling can be performed. Operation becomes possible.

  In the refill container according to the present invention, when the nozzle of the container to be used repeatedly having a nozzle cap can be inserted into the pouring nozzle, the nozzle of the container to be used repeatedly is inserted into the pouring nozzle held horizontally. By tilting the container so that the dispensing nozzle is vertical, a refill container that enables quick refilling is obtained, and the effect of the present invention is maximized. That is, the refill container according to the present invention naturally opens the spout due to the presence of the folded portion obtained by folding one laminated body, so that it is easy to insert the nozzle of the target container, and pour it in accordance with the nozzle. By designing the size of the outlet, it is possible to make the spout exactly fit the nozzle. For this reason, after inserting the nozzle of the container to be repeatedly used into the pouring nozzle held horizontally, the refilling operation can be performed quickly by tilting so that the pouring nozzle becomes vertical.

FIG. 1 is a schematic view showing an embodiment of a refill container according to the present invention. FIG. 2A is a schematic cross-sectional view showing the CC cross section of FIG. Moreover, (2) is a cross-sectional schematic diagram showing the layer structure of the laminate constituting the refill container. FIG. 3A is an enlarged view of the dispensing nozzle portion 32 of the refill container according to the present invention. (2) is a schematic cross-sectional view of the spout 31.

  As shown in FIG. 2 (2), the refill container 1 according to the present invention is a refill container made of a laminate having at least a base material 11 and a sealant layer 12. As shown in FIG. 2, the main body surface laminate 2 and the main body back laminate 3 are provided, the respective sealant layers are opposed to each other, the periphery is sealed, and one laminate is bent with the sealant layer 12 inside. Bending along the line 5 to form a bent portion 6, the main body surface laminate 2 and the main body back surface laminate 3, and the bent portion 6 together with the spout seal portion 24 is used for pouring the contents. An outlet nozzle 32 is formed, and the tip of the outlet nozzle 32 can be formed along the planned opening line 34 to form the outlet 31. Further, the bent portion 6 is provided with a rough surface portion 7 formed by a plurality of scratches on one or more base material layers.

  The first feature of the refill container according to the present invention is that it has a bent portion 6. The bent portion 6 is formed by bending a single laminate at the top with the sealant layer 12 inside, and the bent portion 6 includes a spout seal portion 24 provided at the lower portion of the bent portion 6 and a punching process. Together with the portion 25, an outflow passage 33 for the contents reaching the spout 31 is formed. Due to the elastic action of the laminated body to return in the bent portion 6, the cross section of the outflow passage 33 is always in a state where the upper portion is swollen. For this reason, it becomes possible to ensure the cross-sectional area of the spout 31 widely, and it becomes possible to discharge a lot of contents at once.

  The second feature of the refill container according to the present invention is that the bent portion 6 is provided with a rough surface portion 7 formed by a plurality of scratches on one or more base material layers. In the enlarged view of the dispensing nozzle portion 32 shown in FIG. 3, when opening with the opening knob 8, the tear of the front surface laminate and the tear of the back surface laminate starting from the spout seal portion 24 are respectively scheduled opening lines. It rises along 34, and it encounters in the vicinity of the fold line 5 of the upper part of the pouring nozzle 32, but these two tears do not necessarily correspond at this time. If they match, the spout 31 opens cleanly, but if they do not match, a little of the laminate remains and the tip of the spout nozzle 32 is connected. At this time, since the rough surface portion 7 exists, this portion is easily cut and the spout 31 is opened.

  If the rough surface portion 7 is present, this portion is fragile and can be easily pinched by hand, so that the dispensing nozzle portion 32 can be easily threaded from the opposite direction by hand.

  The width X of the rough surface portion 7 in the direction perpendicular to the folding line 5 is preferably 1.0 mm ≦ X / 2 mm ≦ 20.0 mm. That is, as shown in FIG. 3, it has been found that X / 2 is preferably 1 mm or more and 20 mm or less with respect to the height a of the spout at the spout nozzle 32. In addition, both a dimension and X dimension in FIG. 3 are numerical values measured in a state where the dispensing nozzle 32 is pressed flat. As shown in FIG. 3B, the actual cross-section of the dispensing nozzle is in a state of bulging horizontally due to the elasticity of the laminate. When the width of the spout is b, the larger the b, the larger the opening area of the spout and the better the pourability.

  If X / 2 is less than 1 mm, the effect of providing the rough surface portion cannot be obtained, and if it exceeds 20 mm, the width of the rough surface portion is too large. The tip portion may be cut in a direction not to be used, which is not preferable.

  In the embodiment shown in FIG. 1, the main body surface laminate 2 and the main body back laminate 3 are sealed in the side seal portion 22 and the bottom seal portion 23 to form a bag shape. In an actual container, a filling opening for filling the contents is necessary, but is omitted in FIG. In the embodiment shown in FIG. 1, a filling opening can be provided in the bottom seal portion 23 or the side seal portion 22.

  The unscheduled opening line 34 at the tip portion of the dispensing nozzle 32 is a virtual line indicating the unsealing position, but in order to clarify the unsealing position, printing display or the like may be actually performed. Moreover, it can also be set as the half cut line provided in the outer surface of a main body surface laminated body and / or a main body back surface laminated body. By doing so, it is possible to easily form the spout 31 by tearing the portion of the scheduled opening line 34 by hand. For the half-cut line, a method of forming with a blade and a method of forming by laser processing are generally used, but the method by laser processing is preferable because a uniform and stable cut can be formed.

  The portion to be the spout 31 is preferably provided at a position slightly retracted from the tip of the spout nozzle 32. This is so that the tip of the dispensing nozzle can be held easily by hand. Also, a V-shaped or U-shaped notch or cut line is provided in the spout seal portion corresponding to the planned opening line 34, or the opening knob 8 is provided by processing the tip end portion of the spout seal portion wide. This further improves the ease of opening.

  As a laminated body used for the refill container according to the present invention, a laminated body usually used for flexible packaging bags can be used. As the substrate 11, paper, metal foil, or synthetic resin film composed of one layer or several layers is used. For example, low density polyethylene resin (LDPE), high density polyethylene resin (HDPE), linear low density polyethylene resin (LLDPE), polypropylene resin (PP), polyolefin resin such as polyolefin elastomer, polyethylene terephthalate resin (PET), polyester resins such as polybutylene terephthalate resin (PBT), polyethylene naphthalate resin (PEN), cellulose resins such as cellophane and cellulose triacetate (TAC), polymethyl methacrylate (PMMA) resin, ethylene- Vinyl acetate copolymer resin (EVA), ionomer resin, polybutene resin, polyacrylonitrile resin, polyamide resin, polystyrene resin (PS), polyvinyl chloride resin (PVC), polyvinylidene chloride Resin (PVDC), polycarbonate resin (PC), fluorine-based resin, synthetic resin films and paper, such as urethane resin, a metal foil or the like alone or be used in combination. The base material 11 includes a printing layer and an adhesive layer as necessary.

  As the paper, high-quality paper, piece art paper, coated paper, cast coated paper, imitation paper, and the like can be used. Usually, in order to stably open the spout, embossing may be applied to the spout nozzle. However, when paper is used for the laminate, there is a problem that the paper is cracked by embossing. It was. However, in the present invention, since the spout is stably opened by bending one laminated body and embossing is not required, it is effective to use paper from the viewpoint of environmental considerations. .

  As the sealant layer 12, a polyolefin resin is generally used. Specifically, a low density polyethylene resin, a medium density polyethylene resin, a linear low density polyethylene resin, an ethylene / vinyl acetate copolymer, an ethylene / α Ethylene resins such as olefin copolymers, polypropylene resins such as homopolypropylene resins, propylene / ethylene random copolymers, propylene / ethylene block copolymers, and propylene / α olefin copolymers are used. In addition, a multilayer film in which these resins are combined may be used.

  Specific examples of the structure of the laminate include a film composed of PET / printing layer / adhesive layer / stretched polyamide resin film (hereinafter abbreviated as ONY) / adhesive layer / LLDPE, and ONY / adhesive layer / LLDPE. , ONY / adhesive layer / ONY / adhesive layer / LLDPE, paper / LDPE / aluminum foil / LDPE, paper / LDPE, and the like.

  FIG. 4 is a schematic view showing another embodiment of the refill container according to the present invention, and FIG. 5 (1) is a schematic cross-sectional view showing the DD cross section of FIG. FIG. 5B is a schematic cross-sectional view showing a state in which the container body is opened.

  In this embodiment, the refill container 1 has the main body surface laminated body 2, the main body back surface laminated body 3, and the bottom tape 4, each sealant layer is made to oppose, and the circumference | surroundings are sealed. The bottom tape 4 is bent at the bottom of the container so that the sealant layer is on the outside. One end of the bottom tape 4 forms the bottom seal portion 23 together with the main body surface laminate 2, and the other end is the back surface of the main body. A bottom seal portion 23 is formed together with the laminate 3 to constitute the bottom surface of the container. This type of packaging bag is referred to as a so-called standing pouch, and has a feature that a large-capacity container can be realized because the bottom surface widens greatly.

  The bent portion 6 is formed by bending one laminated body at the top with the sealant layer inside, and the bent portion 6 includes the spout seal portion 24 and the punching portion 25 and the contents reaching the spout 31. An outflow passage 33 is formed. In this way, particularly when the contents are liquid, when the contents are poured out, the contents smoothly flow through the straight outflow passage 33, so that quick dispensing is possible. This feature is more effective in this embodiment because of the large capacity of the container.

  In this embodiment, a part of the bent portion 6 is cut open to form a filling opening 41 for filling the contents. FIG. 3 shows a state where the top opening 21 is formed by sealing the filling opening 41. Thus, when the opening part for filling exists in the top part of a container, there exists an advantage which becomes easy to perform filling operation of the contents.

FIG. 6 is a schematic view showing another embodiment of the refill container according to the present invention.
This embodiment is characterized in that a handle 26 having a shape that fits in the punching portion 25 is provided on the side opposite to the punching portion 25 of the spout seal portion 24 that forms the pouring nozzle 32. By forming the punching portion 25 in the spout seal portion 24, the outflow passage 33 is formed as a protruding spout nozzle 32. As the shape of the punching portion 25, an appropriate shape can be selected according to the structure around the stopper portion of the container that is repeatedly used.

  In order to manufacture the refill container shown in FIG. 6, the laminated body that is slit to a width approximately twice the width corresponding to the height of the container is folded and opposed at the top with the sealant layer surface inside, and the body surface After the laminated body 2 and the main body back surface laminated body 3 are supplied continuously, the bottom tape 4 folded in half so that the sealant layer surface is on the outside is continuously supplied, and necessary sealing is performed. , Punched into a container.

  In order to form the rough surface portion 7, the rough surface portion is formed from the base material surface side in a flat state before the laminate is bent at the top. Moreover, you may form the rough surface part 7 in the base-material surface before forming a laminated body. As a method for forming the rough surface portion 7, a method using a laser processing machine, a method using a rough surface embossing roll, or the like can be used.

  The punching portion 25 is a portion that is originally discarded. However, as shown in FIG. 7, if the handle 26 is shaped so as to be accommodated in the punching portion 25 of the adjacent refill container 27, the material is made of the material. The handle 26 can be added without an increase. Since the handle 26 is present, the refilling operation can be performed by holding the handle 26, so that the refilling operation can be performed more safely and easily.

  In this embodiment, a part of the bent portion 6 is cut open to form a filling opening 41 for filling the contents. In this example, since the punched portion 25 and the handle 26 are present in the side seal portion 22, it is difficult to provide a filling opening having a sufficient width in addition to the bent portion 6. Therefore, it is preferable to provide the filling opening 41 at the bent portion 6.

  FIGS. 8-10 is the schematic diagram which showed the example of a series of refilling operations using the refill container which concerns on this invention. As shown in FIG. 8, the refill container 1 according to the present invention is held, the tip of the dispensing nozzle 32 is cut, and the dispensing port 31 is opened. The nozzle 52 of the repeated use container 51 that has become empty is inserted into the spout 31. In this figure, the repeated use container 51 is a plastic container provided with a nozzle cap 53 having a nozzle 52.

  Next, as shown in FIG. 9, the dispensing nozzle 32 of the refill container 1 is repeatedly inserted into the nozzle cap 53 of the use container 51. Next, as shown in FIG. 10, when the entire arrangement is made so that the dispensing nozzle 32 is vertical while keeping the positional relationship between the reusable container 51 and the refill container 1 constant, the contents in the refill container 1. Things are repeatedly injected into the use container 51 at once.

Thus, the refill container according to the present invention can secure a large-area spout without using a special plastic spigot, and the size of this spout is: Since it can be designed freely according to the shape of the stopper of the intended repeated use container, it is extremely valuable as a dedicated refill container capable of quick refill operation.
Hereinafter, based on an Example, the refill container which concerns on this invention is demonstrated more concretely.
