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 container that is repeatedly used and a container sealing member that seals the refillable container body (see Patent Document 1). .

  Since the refill container described in Patent Document 1 uses two members, ie, a coupling member and a container sealing member, in the cap portion in order to couple the reusable container and the refill container, the cost of the container is high. It must be a thing. In addition, since the refill container is used by screwing it into the opening of the container to be used repeatedly, the connection between the two is reliable, but on the other hand, it is not only cumbersome 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. 5 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, the outlet is clogged, and the outlet is easy to bend. However, there is a problem that the container is removed from the container that is repeatedly used.

  In order to solve the problem that the spout is blocked or bent, a part different from the film is inserted into the spout (see Patent Document 2), or the film near the spout is inflated. Many proposals have been made to secure the opening area by adopting a shape (see Patent Document 3).

  However, these packaging bags have the problem that the process of attaching separate members and the process of applying deep embossing to the film increase, and that the packaging bags cannot be neatly stacked in the packaging bag supply section at the time of filling. The problem and the basic problem that the spout formed by sealing the two front and back films has a sealing part at both ends, so the opening width becomes narrow accordingly and a sufficient opening area cannot be secured. was there. If a sufficient opening area cannot be secured, the time required for dispensing at the time of refilling will become long.

  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 4 and 5). ).

JP 2004-99082 A Japanese Patent Laid-Open No. 5-132069 Patent No. 4110940 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 bent as shown in Patent Documents 4 and 5, there is a problem that the spout is blocked and a problem that the opening area of the spout is insufficient. However, as can be seen from the spout of the flexible packaging bag shown in Patent Document 5, when the spout is set at an angle in consideration of the ease of operation during spout, the opening operability It has been found that there is a problem that becomes unstable.

  FIG. 6 (1) is a view showing the flexible packaging bag disclosed in Patent Document 5, and FIG. 6 (2) is an enlarged view of the spout portion. This soft packaging bag, which is our application, is provided with a dot-like scratch processing c provided so as to cover the cut line a, the V-shaped cutout b, and the cut line a at the spout portion. Nevertheless, if the position of the V-shaped notch b is slightly deviated, the tear of the packaging bag will be disengaged from the cut line a, and there will be a problem that it cannot be opened at the original position of the cut line a. It turns out that there is a possibility.

  The problem to be solved by the present invention is a refill container capable of forming a large-area spout without using a separate member such as a plug, and can be easily and reliably refilled. A container is proposed.

  As a means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a single laminate having at least a base material and a sealant layer is bent with the sealant layer inside, and the bent portion and the main body surface are laminated. The refill container is formed by forming a body and a main body back surface laminate and sealing the periphery, and the bent portion is for pouring the contents together with the front surface laminate, the back surface laminate and the pouring nozzle seal portion. An unsealing knob formed by separating the opening end of the unloading nozzle by a unsealing cut line provided on the unloading nozzle seal portion. The spout is formed by cutting along the planned opening line, the planned opening line is inclined with respect to the bent portion, and the planned opening line is on the planned opening line. An easy-cut process consisting of a plurality of parallel flaw lines is applied, and the tip of the opening cut line is bent in a direction parallel to the planned opening line. is there.

  Further, in the invention described in claim 2, a laminate having at least a base material and a sealant layer is bent with the sealant layer facing outward to form a bottom tape, and between the main body surface laminate and the main body back laminate. The refill container according to claim 1, wherein the refill container has a standing pouch shape that is inserted into the container and sealed at the periphery.

  The invention according to claim 3 is the refill container according to claim 1 or 2, characterized in that a part of the bent portion is cut open to form a content filling opening.

  The refill container according to the present invention is formed by bending a single laminate having at least a base material and a sealant layer with the sealant layer on the inside to form a bent portion, a main body surface laminate, and a main body back laminate. Because it is a refillable container that seals, unlike plastic bottles or containers that use plastic spigots, it can be manufactured only from the laminate for flexible packaging, and can be manufactured at low cost. .

  Further, the refill container according to the present invention bends one laminated body with the sealant layer inside to form a folded portion, and the folded portion includes the front surface laminated body, the back surface laminated body, and the pouring nozzle. Since the pouring nozzle for pouring out the contents was formed together with the seal portion, it was possible to stably secure a large area pouring outlet, and as a result, smooth and quick refilling operation became possible. Further, the spout can be formed easily and reliably.

  In addition, the refill container according to the present invention has a good operability when the content liquid is poured out by inclining the container because the scheduled opening line forming the spout is inclined with respect to the bent portion. .

  In addition, on the planned opening line, easy-cut processing consisting of a plurality of flaw lines parallel to the planned opening line has been applied, and the tip of the opening cut line is bent in a direction parallel to the planned opening line. Therefore, when the unsealing knob is pulled up, the tear of the laminate naturally proceeds along the planned opening line, and it is easy to form the spout at a predetermined position.

  Further, a laminate having at least a base material and a sealant layer is folded with the sealant layer outside to form a bottom tape, and inserted between the main body surface laminate and the main body back laminate to seal the periphery. In the case of a standing pouch shape, it becomes possible to make a refill container with a large capacity having self-supporting properties, and the features of the present invention can be fully utilized.

  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. 5 is a schematic view showing an example of a conventional refill container. FIG. 6 is a schematic diagram showing the soft packaging bag described in Patent Document 5 and its spout.

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. 2 is a schematic cross-sectional view showing the XX ′ cross section of FIG. 1 and shows the layer structure of the laminate constituting the refill container. FIG. 3 is an enlarged view showing details of the dispensing nozzle portion of FIG.

  A 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, and as shown in FIG. The laminate is a refill container formed by bending the sealant layer 12 inside to form the bent portion 6, the main body surface laminate 2, and the main body back laminate 3, and sealing the periphery.

  The bending portion 6 forms a pouring nozzle 32 for pouring the contents together with the front surface laminate 2, the back surface laminate 3, and the pouring nozzle seal portion 24, and the tip of the pouring nozzle 32 is the pouring nozzle. The spout 31 is formed by being cut off along the planned opening line 36 and sealed by the tip seal portion 25.

  An unsealing knob 34 that is separated and formed by an unsealing cut line 35 provided in the dispensing nozzle seal portion 24 is formed below the dispensing nozzle tip seal portion 25. The spout 31 is formed by holding the opening knob 34 and cutting along the planned opening line 36.

  The planned opening line 36 is inclined with respect to the bent portion 6, and an easy-cut process 33 including a plurality of flaw lines parallel to the planned opening line 36 is performed on the planned opening line. The tip 35a of the opening cut line 35 is bent in a direction parallel to the planned opening line 36.

  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 one laminated body at the top with the sealant layer 12 inside, and the bent portion 6 includes the pouring nozzle seal portion 24 and the main body provided below the bent portion 6. Together with the front surface laminate 2 and the main body back surface laminate 3, an outflow passage for 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 path 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.

Further, the second feature of the refill container according to the present invention is that it is cut along the planned opening line 36 with the opening knob 34 separated and formed by the opening cut line 35 provided in the dispensing nozzle seal portion 24. The opening 31 is inclined with respect to the bent portion 6, and a plurality of scratch lines parallel to the opening line 36 are formed on the opening line. Easy cutting processing 33 is performed, and the tip of the opening cut line 35 is bent in a direction parallel to the planned opening line 36.

  If the opening knob 34 is formed by a V-shaped cut or the like, it is completely separated from the spout seal portion, and may be hung up unnecessarily, but as in the present invention. If it is formed by a score line, there is an advantage that it is not hung.

  On the planned opening line 36, an easy-cut process 33 consisting of a plurality of flaw lines parallel to the planned opening line 36 is provided. Therefore, a tear at the time of opening that reaches this range is along the planned opening line 36. High probability of progress. However, if the leading end of the opening cut line 35 simply ends in a straight line, the tear at the time of opening may rarely deviate from the planned opening line and proceed upward.

  Since the opening cut line 35 of the refill container according to the present invention is bent toward the direction parallel to the planned opening line 36, the tear at the time of opening is surely the direction of the planned opening line 36. Proceed to.

  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. Also, a part of the bent portion 6 can be cut open to form a filling opening.

  In the embodiment shown in FIG. 1, the bent portion 6 is disposed horizontally on the top of the refill container 1, but may be disposed vertically on the side surface of the refill container 1.

  Note that the scheduled opening line 36 is a virtual line indicating the opening position, but in order to clarify the opening position, printing display or the like may be actually performed. Moreover, it is preferable that the easy-cut process 33 is a half-cut line provided continuously on the outer surface of the main body surface laminate 2 and the main body back laminate 3. By doing so, it is possible to easily form the spout 31 by tearing the portion of the scheduled opening line 36 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. As the type of laser, a carbon dioxide laser is more preferable. The scheduled opening line 36 is not perpendicular to the ridge line of the bent portion, but is inclined as shown in FIG.

  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. When paper is used for the laminate, cracking may occur in the paper due to deep embossing, so when using it for the refill container according to the present invention, streak embossing is adopted as convex embossing and concave embossing By doing so, the laminated body using paper can be used stably. It is also 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.
In this embodiment, a single laminate having at least a base material and a sealant layer is bent with the sealant layer outside to form a bottom tape 4, and inserted between the main body surface laminate 2 and the main body back laminate 3. A standing pouch is formed by sealing the periphery. In the case of such a shape, since the filling opening for filling the contents cannot be provided in the side seal portion, a part of the bent portion 6 is cut open to form 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.

  The standing pouch-shaped container can easily be a large-capacity container because the bottom tape 4 spreads. Therefore, the feature that the pouring time in the refill container according to the present invention is short can be fully utilized.

  The bent portion 6 is formed by bending a single laminated body at the top with the sealant layer inside, and the bent portion 6 together with the front surface laminated body 2, the back surface laminated body 3, and the dispensing nozzle seal portion 24, An outflow path for the contents leading to the spout is formed. In this way, particularly when the contents are liquid, when the contents are poured out, the contents smoothly flow through the linear outflow passage, so that quick dispensing is possible. This feature is more effective in this embodiment because of the large capacity of the container.

  In the embodiment shown in FIG. 4, easy-cut processing 33 by laser is performed on the planned opening line 36. The easy cut processing 33 in this case is a plurality of half-cut lines provided in parallel. On the other hand, an opening knob 34 is cut out by an opening cut line 35 provided in the pouring nozzle seal portion 24. The opening cut line 35 is formed so as to reach the easy-cutting process 33, and the tip end portion 35 a is bent in a direction parallel to the planned opening line 36. For this reason, opening is easily performed along the easy-cut process 33 by holding the opening knob 34 by hand and pulling it upward.

  In order to manufacture the refill container shown in FIG. 3, the laminated body that is slit to a width approximately twice the width corresponding to the height of the container is folded at the top with the sealant layer surface inside, and is opposed to the main 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.

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.
