  However, this type of conventional refill container often has no head space, and many products are difficult to refill, such as when the seal is peeled off, when the lid is removed, or when the contents are spilled during the refill operation. Moreover, it is difficult to apply to products in which the contents are fine powder and the contents may be scattered during the refilling operation. Furthermore, when refilling, there is a problem that is difficult to apply to contents that are denatured by contact with the outside air or contents that are volatile components evaporate in the outside air and deteriorate in quality.

  Therefore, the present inventors have made various studies in view of such problems of conventional products. As a result, it has been found that the conventional product has a structural problem that it is necessary to open the refill container prior to refilling to provide an opening and then refill the refilled container. In particular, in the case of a pouch, it is easy to fall down and difficult to refill.

  Based on this new knowledge, further diligent examinations and tests were conducted, and from the results obtained, the opening was closed until the contents were refilled from the refill container to the refill destination container, and the internal sealability was kept completely. Prototype products that can be stored and transported with little space for storage and transportation. As a result, we were able to obtain a product that was almost satisfactory.

  Therefore, the object of the present invention is to reduce the possibility that the content is a fine powder even if it is a fine powder, can be easily and reliably refilled, and is less likely to damage the aroma and flavor. An object of the present invention is to provide a refilling container having a barrier property that can be refilled while maintaining the quality of the product.

In order to solve the above technical problem, refill containers having a barrier property according to claim 1 of the present invention, the container body having a high gas barrier property and sealing property, parts, sheet-like cap material Furthermore, the container is a refillable container having a barrier property composed of an overcap, and the part has a cylindrical ring having the same diameter as the opening of the container main body, and a funnel having a taper toward the opening. Further , a sheet-like lid material including a material layer having a barrier property and a lower layer thereof is attached to the upper end of the opening of the ring or the container main body to seal the opening of the container main body. Has a strength weak point formed in the lower layer radially from its center and at a predetermined interval in the circumferential direction, and the container body is turned upside down and the lid is pressed against the mouth of the container to be refilled Along the weak point Press Te breaking, the contents were characterized by being so exploitable directly poured from the mouth portion of the container of the refill destination while collecting centrally funnel.

The container main body having a high gas barrier property according to the present invention is composed of a single body or a laminate mainly composed of paper, aluminum, or a plastic film. Therefore, it is desirable to provide the intermediate layer with a metal foil layer, a metal vapor deposition layer, a metal oxide vapor deposition layer, or the like. The innermost layer includes a composite material in which a synthetic resin layer is laminated, and is formed as a pouch, a paper pack, a paper tube, or a folded sleeve-like paper container. The upper end of the body portion of the container body includes a flange that protrudes outward or an annular winding portion (curl portion) that is annularly wound outward. It also includes parts with flanges projecting outward at the upper end of the ring. The overcap that covers the upper end of the container body protects the lid from being opened by an external force such as vibration during transportation, and is formed of, for example, a polypropylene resin material. Further, a ring of a part formed of, for example, a polyethylene resin material is fitted and attached to the inner peripheral surface of the upper end of the container body. As a mounting method, if the ring outer peripheral surface is fixed to the inner peripheral surface of the upper end of the container body by means such as heat fusion or adhesion, or if a flange is provided, this flange is mounted on the upper edge of the container body. It is fixed by means such as heat fusion or adhesion. Then, for sealing the opening of the container body, the metal foil layer or metal deposition layer, sheet further having a barrier made of a composite material synthetic resin layer is laminated with a metal oxide or the like deposited layer Jo lid material, is adhered by means such as thermal fusion or adhesion on the upper end face of the opening of the container body, it is intended to seal the opening of the container body. The upper end surface of the opening of the container main body includes the curled portion and the flange of the ring in addition to the so-called upper end surface of the body portion. On the back surface of the lid member, strength weak points including perforations, cut lines, and the like are provided at predetermined intervals in the circumferential direction from the center to the front of the material layer having the barrier property. In use, the container body is turned upside down, the lid material is pressed against the mouth of the container to be refilled, such as a glass bottle, and pushed along the weak point of the strength, and the contents are collected in the center with a funnel. It was possible to pour directly from the mouth of this refilled container.

In the refill container having the barrier property configured as described above, the overcap is removed, and then, as shown in FIGS. 5 and 6, the container body is inverted, and the funnel of the parts is an example of the refill destination container. Address to the position where it can fit inside the mouth of the jar. Contents such as instant coffee in the container body have also flowed down into the funnel of the hopper, but are held by the lid. Next, as shown in FIGS. 7 and 8, a pressing force is applied to the container body so as to push the funnel toward the mouth of the jar. This pressing force acts as a force for the cylindrical portion that rises in a cylindrical shape from the mouth portion of the jar, generally, the main body to push through the lid member. That is, the mouth portion of this jar functions as a force that pushes up the lid member and pushes it into the space having a triangular cross section between the ring of the part and the funnel. The lid member loaded with the pressing force is divided into a plurality of divided pieces along, for example, perforations and cut lines, which are strength weak points provided in advance radially on the lid member. At the same time funnel This enters the mouth of the jar. As a result, the opening of the part funnel is opened, and the contents such as instant coffee in the container main body are guided and flowed down into the jar all at once while being guided to the center by the part funnel.

  Thus, in the refill container having the barrier property of the present invention, in transferring the contents from the refill container to the refill destination container, after opening the lid (sealing seal), tilting the refill container, Unlike conventional products that perform refilling work upside down, as described above, after removing the overcap, the refilling container is turned upside down and placed on the mouth of the refilling container. Thereafter, the refill container is pushed downward to press the lid material against the mouth of the container to be refilled, and the lid material is broken along the strength weak point by the pressing force and opened.

Therefore, this invention has the following effects.
Unlike the conventional standing pouch and the like, the refilling container having the barrier property of the present invention is designed to push the cover material by pressing the container body against the mouth of the refilling container. So, it is easy to communicate directly between the container body and the container to be refilled, and unlike the conventional products that need to pay attention to the container falling after opening, it is also necessary to worry about the refill container falling down. In addition, the refilling operation can be performed easily and reliably by a very simple operation. In addition, it is possible to reduce the possibility that the contents touch the outside air more than necessary or the volatile components are evaporated, and the possibility that the fragrance and flavor are impaired is reduced.

  Moreover, since the target container is a pouch or a rectangular tube paper container, it can be stored and transported in the folded sleeve state unlike conventional paper packs and paper tubes. It can be provided as an advantageous container for storage and transportation with less space for transportation.

  Hereinafter, an embodiment in which the refilling container having the barrier property of the present invention is applied to an instant coffee refilling pouch 1 will be described in detail with reference to the drawings.

  First, as shown in FIGS. 1 and 2, the refilling pouch 1 includes a pouch 2 that is a container body, a part 3, a sheet-like lid member 4 having a barrier property, and an overcup 5.

  The pouch 2 has a three-side seal configuration and includes a bottom seal portion 6, side seal portions 7 and 8, and an opening 9. In addition, in this invention, it cannot be overemphasized that a pouch is not limited to said form, The bottom seal | sticker part 6 is self-supporting form, Furthermore, it can apply also to packaging bags, such as a pillow and a gusset.

  The base material of the pouch 2 is a composite material having a high gas barrier property (oxygen, water vapor, content-derived volatile component) in which transparent vapor-deposited polyethylene terephthalate, biaxially stretched film (ONy), and polyethylene are laminated in order from the outside. Adopted. Various known techniques are employed as the laminating means. For example, it is a general method such as laminating or coating. As the base material, a biaxially stretched film (ONy: 12 μm) is coated on both sides of the front and back with an alumina vapor-deposited film (GL-AE: 12 μm), and a polyethylene sealant layer 3 is laminated on the innermost layer. Yes. Two substrates as described above are superposed, and as shown in FIG. 1, the bottom and the left and right sides are sealed to produce a pouch 2 that opens upward.

  A cylindrical part 3 is fitted into the opening 9 of the pouch 2 as shown in FIG. The part 3 is made of an appropriate resin material such as polyethylene (PE) or polypropylene whose thickness is set to 0.8 mm. As shown in FIG. 1, the part 3 includes a rising wall 3 </ b> A (hereinafter simply referred to as a ring) as a ring that does not have an outward flange at the upper end. The ring 3A is fitted into the opening 9 with its upper end positioned at the same height as the upper end of the opening 9 of the pouch. In addition, a funnel 3B is provided integrally from the lower edge of the ring 3A, and is a wall that is sequentially inclined upward and toward the center. The taper angle of the funnel 3B is set to at least 20 °, more preferably 40 to 45 °.

  The part 3 is firmly aligned so that the upper end of the funnel 3B is arranged at substantially the same height as the upper end of the opening 3 of the ring 3A and the pouch 2, that is, substantially in the same plane. 9 and is appropriately joined to the inner peripheral surface of the opening 9. As the bonding means, the most preferable means such as heat fusion, high-frequency welding, and the use of an adhesive are appropriately adopted.

The upper end of the part 3 is sealed with the lid member 4 having a barrier property.
As shown in FIG. 3, the lid 4 having the barrier property has a polyethylene foil as an innermost layer 10, a polyethylene terephthalate layer 11 outside the sealant layer 10, and an adhesive layer 12 outside the metal foil. A composite sheet having a high gas barrier property to which the layer 13 is attached is employed. Further, from the innermost sealant layer 10 to the adhesive layer 12 above, a plurality of strength weak points 14 are provided radially from the center of the lid member 4 as shown in FIG. By providing this strength weak point portion 14, the metal foil layer 13 including the sealant layer 10 is also easily torn and can be easily opened.

  As shown in FIGS. 1 and 2, the overall shape of the lid member 4 is substantially the same as the opening 9 of the pouch 2, specifically, a circular shape having a diameter of about 80 mmφ, and the sparse peripheral part 4 A is a part 3. Is appropriately attached to the upper end of the rising wall 3A. Generally, heat fusion means is employed. In this case, however, the upper end edge of the funnel 3B, that is, the upper edge of the opening 3B1 is merely contacted. This is because the opening 3B1 of the funnel 3B can be opened quickly and easily.

  Further, the strength weak point portion 14 is formed by a perforation or a cut line (perforation in the illustrated example), and is provided so as to reach the adhesive layer 12 from the innermost sealant layer 10. The perforation or cut line which is the strength weak point portion 14 and the metal foil layer 13 including the innermost sealant layer 10 are easily broken and easily opened. As shown in FIGS. 1 and 4, the perforation or the cut line has three straight lines intersecting each other at the center, and the length of the perforation is set to 9 mm and the joint is set to 1 mm. The number of three is a minimum number for achieving the intended purpose of the present invention. Further, although it depends on the size of the lid member 4, the desirable upper limit is five. On the contrary, if the number is 5 or more, there is a possibility that the strength of the lid 4 is weakened, which is not preferable. Ideally 3-4.

  The overcap 5 is made of a suitable resin such as high density polyethylene (HDPE) or polypropylene having a thickness of about 0.8 mm, and is fitted outside the opening 9 of the pouch 2 so that the lid 4 is It works to protect and keep the interior hygienic.

Task of accommodating the instant coffee P powdery inside the pouch 2 are generally carried out through the opening 3B1 of funnel 3B.

Next, how to use the pouch 2 configured as described above will be described.
First, the overcap 5 is removed, and then, as shown in FIGS. 5 and 6, the pouch 2 is turned upside down, and the funnel 3 </ b> B of the part 3 is placed inside the cylindrical mouth portion 15 </ b> A of the jar 15, which is an example of a refill destination container. Address the position where it can be fitted. The instant coffee P in the pouch 2 flows down from the part 3 into the funnel 3 </ b> B, but is held by the lid member 4. Next, as shown in the image 7 and FIG. 8, a pressing force is applied to the pouch 2 so as to push the funnel 3 </ b> B toward the mouth portion 15 </ b> A of the jar 15. This pressing force acts as a force point for the cylindrical portion rising from the mouth portion 15 </ b> A of the jar 15, generally a cylindrical shape from the main body, to push through the lid member 4. That is, the mouth portion 15A of the jar 15 functions as a force that pushes up the lid member 4 and pushes it into the space S having a triangular cross section between the ring 3A of the part 3 and the funnel 3B. The lid member 4 loaded with the pressing force is provided with perforations that are strength weak points 14 in a radial manner. Therefore, it is very easy to break and divide into a plurality of divided pieces along the perforation. Is done. At the same time, the funnel 3B enters the mouth portion 15A of the jar 15. As a result, the opening 3B1 of the funnel 3B of the part 3 is opened, and the instant coffee P in the pouch 2 is guided down into the jar 15 all at once while being guided to the center by the funnel 3B of the part 3. The refill container 1 that has been refilled into the jar 15 is discarded.

  Therefore, the ring 3A is completely sealed by the lid material 4 until the lid material 4 is opened, and does not come into contact with the atmosphere, so that the air tightness in the pouch 2 is kept high. Further, the funnel 3B fitted inside the mouth portion 15A of the jar 15 does not spill the instant coffee P to the outside of the jar 15, and does not allow the outside air to be touched more than necessary, so that the aroma and flavor are impaired. The risk of being lost can be reduced as much as possible.

  As a result of performing a performance test of the finished lid member 4, the central portion was successfully broken. Incidentally, the breaking strength was 100 N or less. Moreover, the example which the cover material 4 peels from the upper end of the ring 3A and the opening part 9 of the pouch 2 also at the time of high temperature preservation was not seen. Further, the barrier property of the entire lid member 4 was as good as that of the aluminum lid member. There was no occurrence of cycles compared to the hot melt lid.

Next, another preferred embodiment will be described in detail below.
In this example, as shown in FIG. 9, a refillable container 1 having a barrier property is used as a container body 2 in place of a pouch, and a rectangular container of a type formed from a folding sleeve, that is, a rectangular tubular paper. This is applied to the container 20.

  Therefore, the other components, the sheet-like lid material having a barrier property, and the overcap are only formed in a square shape in plan view according to the shape of the applied container. Differently, the material and manufacturing method are the same as those in the above embodiment. Therefore, detailed description thereof will be omitted, and only the configuration different from the above embodiment will be additionally described.

  Therefore, a rectangular container 20 of the type formed from this folding sleeve is connected to four side plates 21, 22, 23, 24 and one side plate as shown in FIG. And a cylindrical body 26 having an adhesive piece 25 connected to an adjacent side plate, and one top 27 of the body 26 is opened, and the other opening is folded to form a bottom 28. It is a paper container formed.

  As shown in FIG. 10, the materials for forming the rectangular container 20 are, in order from the outside, a low-density polyethylene layer (LEDP) 201, a paper layer 202, an ethylene methacrylic acid copolymer resin (EMAA) 203, aluminum. A layer (AL) 204, a polyethylene terephthalate layer (PET) 205, and a low-density polyethylene layer (LDPE) 206 are laminated, and a composite material having high gas barrier properties (oxygen, water vapor, content-derived volatile components) is employed. The

  As shown in FIG. 10, such a container 20 is provided with a necessary print layer 207 by first printing on a web 202 as a base material. Next, thermoplastic resin layers 201 and 203 are formed on both surfaces of the web 202. As the lamination method, for example, a melt-extrusion laminating method in which a molten thermoplastic resin such as polyethylene is extruded into a film shape by an extruder, and the rolled paper is pressed and laminated while the film is in a molten state is employed. The thermoplastic resin may be formed separately on the inner surface side and the outer surface side, or the thermoplastic resin may be formed simultaneously on the inner surface side and the outer surface side using a co-extruder.

  Finally, the winding paper 202 on which the thermoplastic resin is formed is cut into a desired dimension to obtain a laminated sheet.

  The laminated sheets that have been cut off are marked with a ruled line at a necessary location and punched into a blank sheet 29 one by one. Next, as shown in FIG. 11 (B), the outer side surface of the adhesive piece 25 of the blank sheet 29 punched out and the inner side surface of the side plate 21 to which the adhesive piece 25 is heat-sealed are, for example, hot air And the blank sheet 29 is folded into a folding sleeve.

  Since the blank sheet 29 can be stored and further transported in a folded sleeve shape, unlike conventional paper cups and paper tubes, the storage and transport space is low, which is very advantageous in this respect. .

  Next, by setting the completed sleeve 30 in a dedicated filling machine, as shown in FIG. 11 (C), the lower end of the sleeve 30 is bent and pasted to form a bottom. Further, in FIG. 11 (D) As shown, the upper opening 31 is internally fitted with a part 32 pre-formed in the same shape as the opening 31, and the container is thermally fused to the innermost layer, high frequency welding, use of an adhesive, etc. It is suitably stuck and fixed by the most preferable means.

  After filling the contents, as shown in FIG. 9, the cover member 33 cut out in a square shape on the part 32 is applied to the upper end edge of the opening 31 by heat fusion, high frequency welding, adhesive use, etc. It is stuck and fixed by a preferable means. And finally, the overcap 34 is covered, and the refill container provided with the barrier property of this invention is completed.

  It should be noted that either the bottom molding or the part 32 mounting order may be first. Furthermore, the instant coffee sea P may be filled from the part 32 side or from the bottom. When filling from the bottom, the bottom is formed after filling with the container upside down. Moreover, although the square-shaped part 32 was employ | adopted, it can apply also to a circular shape and another shape. In this case, the sleeve only needs to be able to insert the part 32 by being expanded and distorted. Furthermore, it is possible to top-curl the upper end edge like a paper cup after sleeve molding. In this case, a flange for attaching the lid 4 to the part 32 is not necessary.

  Since the method of using the refill container having the barrier property according to the other embodiment configured as described above is as described in detail in the first embodiment, it is omitted here.

  In the above description, instant powdered coffee is used as the contents, but the present invention can be applied to other fluids other than food and non-food. For example, water-soluble milk (powdered milk), cocoa, tea, or a combination thereof. Further, it includes dried mashed potatoes and other dried foods, sauce or gravy powder, soup powder, and toner for copying machines.

  Further, as an alternative to the jar 15, the present invention can be applied to a coffee powder tank of a coffee making device, and a toner replenishing container of a copying machine.

  A transparent vapor-deposited polyethylene having a thickness of 12 μm was used as a base material, a biaxially stretched film (ONy) having a thickness of 15 μm was used as an intermediate layer, and a polyethylene film having a thickness of 50 μm was used as a sealant layer. Moreover, using a polyurethane adhesive for retort as an adhesive between each layer, a laminated material of transparent vapor-deposited polyethylene / adhesive / biaxially stretched film / adhesive / polyethylene film configuration is created with a dry laminating machine, Using the laminated material, a pouch 2 having an effective inner diameter of 245 mm × 280 and having a three-sided seal shape was obtained. The seal width is 8 mm. Next, by injection molding using high-density polyethylene (Mitsui Chemicals 2100K), the outer diameter of the funnel is 77.6 mm, the opening diameter of the funnel is 34 mm, and a flange with a width of 2 mm overhanging is provided to heat-seal the lid. A part having a ring was prepared. Both the funnel and the ring were formed to have a thickness of about 0.8 mm. Furthermore, a laminated material of [upper] aluminum foil layer (9 μm) which is metal foil layer 10 / adhesive layer / polyethylene terephthalate layer (12 μm) / polyethylene layer (60 μm) which is a sealant layer [lower] is prepared, A lid member was produced using this laminated material. Further, in this lid member, six straight perforations were put under the uppermost aluminum foil layer at a predetermined interval in the circumferential direction and radially from the center. The perforation length was 9 mm and the perforation joint length was 1 mm. Furthermore, the overcap was obtained by the same manufacturing method as the above parts, using polypropylene and making the top plate part and the hanging wall part 0.8 mm thick.

First, by the laminating method, for the container body of the sleeve assembly method, [outside of the container] low density polyethylene layer (20 μm) / paper layer (basis weight 400 g / m ² ) / adhesive layer / ethylene methacrylic acid copolymer heavy resin ( 25 [mu] m) / adhesive layer / aluminum foil layer (7.0 [mu] m) / polyethylene terephthalate layer (12 [mu] m) / adhesive layer / low density polyethylene layer (60 [mu] m) [inner side of container]. Further, the part 32, the lid member 33, and the overcap 34 were formed in a rectangular shape by the same method as in Example 1.

  First, prior to forming the thermoplastic resin layer on both sides, the obtained base material is printed in advance. Next, the web is cut into a desired size to obtain a laminated sheet. Further, a ruled line is put in a necessary portion of the laminated sheet that has been cut, and the blank sheet 29 is punched one by one. The outer side surface of the adhesive piece 25 of the blank sheet 29 that has been punched and the inner side surface of the side plate 21 to which the adhesive piece 25 is heat-sealed are attached to the inner side surface of the side plate 21 by a hot air sealing method. Thereafter, the blank sheet 29 is folded into a bent sleeve shape. Next, the completed sleeve 30 is set in a dedicated filling machine, and the lower end of the sleeve 30 is bent and adhered by a hot air seal method to form the bottom portion 28. Further, the opening portion 31 is formed in the upper opening portion 31. A part 32 molded in advance in the same shape as 31 was fitted inside and adhered and fixed to the innermost layer of the container 20 by an ultrasonic sealing method. After filling with instant coffee P, a cover material 33 cut out in a square shape on the part 32 was stuck and fixed on the flange 32C of the ring 32A by heat sealing. And finally, the overcap 34 was covered, and the refill container provided with the barrier property of this invention was obtained.

  The refill container having barrier properties obtained by the above-described Examples 1 and 2 of the present invention is scattered around even if the content is fine powder compared to a conventional pouch or paper container, and further a paper tube. It has been found that it can be refilled easily and reliably, and the aroma and flavor are less likely to be impaired, and the original quality is maintained well. At the same time, it was found that the container can be provided as an advantageous container for storage and transportation because it has little storage and transportation space.
