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. For example, in the case of a container in which a spout is simply formed in a flexible container made of a soft wrapping film, it is difficult to maintain the shape of the mouth, and the spout may be bent and the spoutability may deteriorate. Even in the case of a container in which the spout is reinforced by embossing, embossing alone is not sufficient, and the spout may be bent similarly. For this reason, refilling took time, and during that time, there was always a sense of uneasiness that contents spilled from the main body container nozzle, and careful work was forced.

  In addition, in the case of a refillable container with a molded tube cap attached to the spout, there is no problem that the spout is bent, but when the molded tube is installed, the tube may fall off or the film may be torn. There is a problem that it is likely to occur. In addition, when filling unfilled empty containers in the filling machine, they are not stacked flat, so that it is difficult to arrange empty containers and the suitability of the filling machine is poor. Further, in the use stage, when opening the spout, there is an inconvenience that a knife or a scissors is required to cut the tube portion.

  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).

JP 2004-99082 A

  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.

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

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. Each sealant layer is opposed to each other and the periphery is sealed, and a single laminate is folded with the sealant layer inside to form a bent portion, the main body surface laminate, and the main body back laminate. The bent portion, together with the spout seal portion, forms an outflow passage for pouring out the contents, and the tip of the outflow passage forms a spout by cutting along the planned opening line. 1/10 × (A ² / π) (mm ² ) ≦ B (mm ² ) ≦ A where A (mm) is the width of the outlet and B (mm ² ) is the opening cross-sectional area of the spout. ² / [pi and satisfy the relationship (mm ²⁾ A refill container that.

The invention according to claim 2 is a refill container comprising a laminate having at least a base material and a sealant layer, comprising a main body surface laminate, a main body back laminate, and a bottom tape, and each sealant layer. Face each other, seal the periphery, bend one laminate with the sealant layer inside, forming a bent portion, the body surface laminate and the body back laminate, the bottom tape, The bottom tape is formed at the bottom of the container and bent, and one end of the bottom tape forms a bottom seal portion with the main body surface laminate and the other end forms a bottom seal portion, respectively. Together with the outlet seal portion, an outflow passage for pouring out the contents is formed, and the tip of the outflow passage is cut along the planned opening line to form a spout, and the width of the spout is set to A (mm ) And spout When the opening cross-sectional area was B (mm ^2), that satisfies the relationship of ^{1/10 × (A 2 /} π) (mm 2) ≦ B (mm 2) ≦ A 2 / π (mm 2) The refill container is characterized.

  The invention according to claim 3 is characterized in that it is formed as a pouring nozzle protruding from the outflow path by forming a punching portion in the pouring outlet seal portion. Refill container.

  The invention according to claim 4 is characterized in that a handle having a shape that fits in the punching portion is provided on the side opposite to the punching portion of the spout seal portion that forms the pouring nozzle. The refill container according to any one of Items 1 to 3.

  The invention according to claim 5 is characterized in that the scheduled 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. It is a refill container of any one of Claims.

  The invention according to claim 6 is the refill container according to any one of claims 1 to 5, 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 outflow passage for pouring out the contents is formed together with the outlet seal portion, it is possible to stably secure a large-area linear outflow passage, and as a result, smooth and quick refilling operation becomes possible. It was.

Furthermore, the tip of the outflow passage is cut along the planned opening line to form a spout, the width of the spout is A (mm), and the opening cross-sectional area of the spout is B (mm ² ). 1/10 × (A ² / π) (mm ² ) ≦ B (mm ² ) ≦ A ² / π (mm ² ) so that a wide opening cross-sectional area is secured. In addition, since it can be easily inserted into the nozzle cap of the container body to be used repeatedly and the flow rate at the time of pouring can be secured, a quick refilling operation can be stably performed.

  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, by forming a punching portion in the spout seal portion, when forming the spout nozzle as a protruding outflow passage, a spout nozzle shape that matches the nozzle cap of the container body to be used repeatedly is realized. Therefore, the refilling operation can be performed more smoothly.

  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. In addition, since the handle has a shape that fits in the punched portion, the laminate is not wasted when it is manufactured by punching from a continuous laminate.

  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 according to 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.

Hereinafter, the refill container according to the present invention will be described in detail with reference to the drawings.
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.

  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. The bent portion 6, the main body surface laminate 2 and the main body back laminate 3 are formed, and the bent portion 6 together with the spout seal portion 24 forms an outflow passage 33 for pouring the contents. The spout 31 can be formed by cutting the tip of the outflow passage 33 along the planned opening line 34.

The greatest 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 laminated body at the top with the sealant layer 12 inside, and the bent portion 6 together with the spout seal portion 24 provided at the lower portion of the bent portion 6,
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. At the same time, since the cross section of the outflow passage 33 is expanded, the outflow passage 33 is less likely to be bent during the refilling operation.

As a further feature of the refill container according to the present invention, as shown in FIG. 3, when the width of the spout is A (mm) and the opening cross-sectional area of the spout is B (mm ² ), It is characterized by satisfying the relationship of 1/10 × (A ² / π) (mm ² ) ≦ B (mm ² ) ≦ A ² / π (mm ² ). This relational expression shows that the opening cross-sectional area B (mm ² ) of the spout is larger than 1/10 of A ² / π (mm ² ), which is the theoretical maximum value of the cross-sectional area of the opening. As a result, a wide opening cross-sectional area B of the spout is ensured, it is easy to insert into the nozzle cap of the container body to be used repeatedly, and a large flow rate of contents during refilling operation is secured. Therefore, a smooth and quick refilling operation is possible.

In addition, A dimension in FIG. 3 is a numerical value measured in the state which pressed the spout 31 flat. As shown in FIG. 3B, the actual cross section of the spout is in a state of bulging horizontally due to the elasticity of the laminate. The opening cross-sectional area of the spout at this time is B (mm ² ). A ² / π is the opening cross-sectional area of the spout when the spout is assumed to be a perfect circle, and this value is the maximum value of the cross-sectional area of the spout opening.

When 1/10 × (A ² / π) (mm ² )> B (mm ² ), the cross-sectional area of the opening of the spout is small, making it difficult to insert it into the nozzle cap of the container body that is used repeatedly. There is a case. Moreover, the flow rate at the time of extraction cannot be secured, and there is a possibility that a quick refilling operation cannot be performed.

  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 scheduled opening line 34 at the tip of the outflow passage 33 is a virtual line indicating the opening position. However, in order to clarify the opening 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 outflow passage 33. This is so that the tip of the outflow passage can be easily held by hand. Ease of opening is also possible by providing a V-shaped or U-shaped notch or cutting line in the spout seal portion corresponding to the planned opening line 34, or by processing the tip end portion of the spout seal portion wide. Is further improved.

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), polybutylene terephthalate resin (PBT)
Polyester resins such as polyethylene naphthalate resin (PEN), cellulose resins such as cellophane and cellulose triacetate (TAC), polymethyl methacrylate (PMMA) resins, ethylene-vinyl acetate copolymer resins (EVA), ionomers Resin, polybutene resin, polyacrylonitrile resin, polyamide resin, polystyrene resin (PS), polyvinyl chloride resin (PVC), polyvinylidene chloride resin (PVDC), polycarbonate resin (PC), fluorine resin, A synthetic resin film such as urethane resin, paper, metal foil, or the like is used alone or 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 a single laminate at the top with the sealant layer on the inside, and the bent portion 6 together with the spout seal portion 24 and the punching portion 25 reaches the spout 31. The material outflow passage 33 is formed as a protruding nozzle 32. 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 The laminated body 2 and the main body back surface laminated body 3 are supplied continuously, and the bottom tape 4 folded in half so that the sealant layer surface is on the outside is continuously supplied, and the side seal portion 22 and the bottom seal are supplied. After performing necessary seals such as the portion 23 and the spout seal portion 24, it is punched out into a container.

  The punching portion 25 is a portion that is originally discarded. However, as shown in FIG. 6, 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 particularly made of 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 exist 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.

  7-9 is the schematic diagram which showed the example of a series of refilling operations using the refilling container which concerns on this invention. As shown in FIG. 7, the refill container 1 according to the present invention is held, the tip of the dispensing nozzle 32 is cut, and the spout 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. 8, the dispensing nozzle 32 of the refill container 1 is repeatedly inserted into the nozzle cap 53 of the container 51 for use. Next, as shown in FIG. 9, 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.
