Description

  The present invention relates to a combined container package in which an inner container filled with contents and an outer container are combined, an inner container package for refilling used in the combined container, and an inner container.

  Containers suitable for transportation from a factory, display at a store, use by a purchaser, and the like are used for commodities containing powder or fluid as contents. Since the powder or fluid itself is indefinite, the container preferably has a relatively high rigidity and a function of holding the contents in a predetermined form. On the other hand, when the purchaser uses up the contents, the container becomes a disposal object. A container having high rigidity tends to increase the environmental load due to disposal. In view of this point, there has been proposed a combined container package in which an inner container that directly stores contents and an outer container that stores the inner container are combined (see, for example, Patent Document 1).

  FIG. 23 shows an example of a conventional combination container package. The combination container package X shown in the figure includes an inner container 91, an outer container 92, and a content Ct. The inner container 91 directly stores the contents Ct and is made of, for example, a relatively soft resin film. In the same figure, the state where the upper part of the inner container 91 was opened is shown. The outer container 92 has a box part 93 and a lid part 94. The box part 93 is made of a relatively hard plastic or the like and accommodates the inner container 91. The lid portion 94 is used for opening and closing the box portion 93. The purchaser purchases the combined container package X in the first purchase and obtains the contents Ct. Thereafter, when the content Ct is used up, only the inner container 91 is discarded. Then, the purchaser purchases only the inner container package including the contents Ct and the inner container 91 in the next purchase, and stores the new inner container package in the box portion 93 of the outer container 92 that is empty. In this way, by using the outer container 92 a plurality of times and using the inner container package including the inner container 91 for refilling, the environmental load due to disposal can be appropriately accommodated while containing the irregular shaped contents Ct. Can be reduced.

  However, since the inner container 91 made of a relatively soft material is filled with the irregular content Ct, the posture of the inner container 91 is disturbed even in the state of being accommodated in the box portion 93 of the outer container 92. there is a possibility. In such a case, the contents Ct may be spilled unjustly. It is not easy to provide a means for appropriately fixing the soft inner container 91 in the outer container 92, and there are problems such as complicating the outer container 91 and forcing the user to perform fixing work.

The content Ct is not particularly limited as long as it is accommodated in the inner container A1, and various solids and liquids can be adopted. Examples of the contents Ct include daily necessities, foods, pharmaceuticals, and industrial articles. For example, when the content Ct is a food, examples of the content Ct include powders such as powder seasonings and liquids such as oil.

  The inner container A1 is directly filled with the contents Ct, and is intended to be used for refilling by being accommodated in the outer container C1. As shown in FIGS. 2 to 7, the inner container A <b> 1 includes a base material 1 and a soft packaging material 2. An inner container package D1 is constituted by the inner container A1 and the contents Ct.

  The base material 1 constitutes a portion harder than the soft packaging material 2 in the inner container A1, supports the soft packaging material 2, and at least functions to seal the soft packaging material 2 during transportation. In the present embodiment, the base material 1 includes a base material 11 and a covering material 12. In addition, the base material 1 of this structure is an example, For example, the structure which does not have the coating | covering material 12 but consists only of the base material 11 may be sufficient. In this case, the base material 11 is preferably provided with an opening means (for example, a perforation line) for taking out the contents Ct.

  The base material 11 is an element that becomes a base of the base material 1. As the base material 11, so-called coated paper having a resin layer provided on the surface, synthetic resin sheet, or the like is adopted in addition to a common baseboard made of thick paper, so-called non-coated paper, plain paper, synthetic paper or the like. sell. As these, various sheet materials such as a single layer sheet and a laminated sheet in which two or more of these sheets are laminated and bonded can be used. In the present embodiment, a case where a substantially rectangular mount made of thick paper is used as the base material 1 will be described as an example. The base material 1 is not limited to a rectangular shape, and may be a polygon other than the rectangular shape, a circular shape, an elliptical shape, or the like.

  The base material 11 has an extending portion 13 and a take-out hole 14. The extending portion 13 is a portion that extends outward from a bag portion 21 of the soft packaging material 2 described later. More specifically, as shown in FIG. 7, the extending portion 13 extends outward from the opening end 211 of the bag portion 21 in the horizontal direction substantially perpendicular to the depth direction of the bag portion 21. . In the present embodiment, the extending portion 13 is provided over the entire circumference of the opening end 211.

As shown in FIG. 2, in the present embodiment, the take-out hole 14 is provided near the center of the base material 11 and has a substantially rectangular shape. For example, when taking out the content Ct of the powder, the content Ct can be scraped off using the edge of the take-out hole 14. The shape and position of the take-out hole 14 are not particularly limited as long as the content Ct can be taken out.

  The covering material 12 is for sealing the contents Ct by closing the take-out hole 14 of the base material 11 at the time of transportation from a factory or display at a store. Moreover, the coating | covering material 12 comprises the opening means which opens inner container A1 by peeling from the base material 11 after purchase. Although the specific configuration of the covering material 12 is not particularly limited, for example, a relatively thin film having heat-sealing properties such as polyolefin resin, tack paper (tack film) coated with an adhesive, and the like are used. The material 11 is detachably bonded. The covering material 12 may be a single layer or a plurality of layers, and may include a layer having functions such as light shielding properties and gas barrier properties such as an aluminum layer.

  The soft packaging material 2 defines an accommodation space for accommodating the contents Ct together with the base material 1. As the material of the soft wrapping material 2, a material softer than the material of the base material 1 and the box 3 of the outer container C1 described later is used, and various materials are used regardless of whether they are transparent, opaque, thick, or thin. In this embodiment, the case where the sheet | seat for containers generally called a pouch container is used as a material of the soft-packing material 2 is demonstrated as an example. As shown in FIG. 4, when the soft packaging material 2 of the present embodiment is placed on a display shelf or the like in a store, the lower portion can be deformed into a shape along the display shelf by the weight of the contents Ct. Is.

  In the case of this embodiment, the sheet | seat of the soft wrapping material 2 is comprised from a resin film. The resin film is required to have basic performance as a package, such as impact resistance, wear resistance, and heat resistance. Moreover, since the sealed accommodation space is usually formed by heat sealing, the sheet is also required to have heat sealing properties. As the sheet, a multilayer sheet having a base film layer and a sealant layer that imparts heat sealability is suitable. When high gas barrier properties and light shielding properties are required, the base film layer and the sealant layer It is preferable to provide a barrier layer therebetween. In addition, you may provide barrier property to the base film layer itself. In this case, a multilayer sheet having a barrier layer and a sealant layer is obtained using the barrier layer as a base film layer.

  Here, constituent materials of the base film layer, the sealant layer, and the gas barrier layer are exemplified. In addition, lamination | stacking of these each layer can be performed by the conventional lamination method, for example, the co-extrusion lamination, the dry lamination by an adhesive agent, the heat lamination which adhere | attaches with a heat | fever by pinching | interposing a heat adhesive layer.

  As the film constituting the base film layer, polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP) etc.), polyamide (nylon-6, nylon-66 etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), poly A stretched or unstretched film of one layer or two or more layers composed of ether sulfone (PES) or the like can be exemplified.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. The stretched or unstretched film can be exemplified.

  The gas barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or any synthetic resin film (for example, a base film layer). ), And a film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide, or silica.

  The soft packaging material 2 can be provided with a printed layer (not shown) for displaying the product name of the contents, the product description such as raw materials and usage precautions, and other various designs. For example, the printing layer can be formed on the inner surface of the base film layer by a known method such as gravure printing.

  As shown in FIGS. 2 to 7, the soft wrapping material 2 includes a bag portion 21 and a bonded portion 22. The bag part 21 is directly filled with the contents Ct. In this embodiment, the bag part 21 is formed using the cylindrical film material so that it may mention later, and the bottom gusset 221 is formed. The bottom gusset 221 is a portion of the tubular film that is opposite to the side on which the base material 1 is provided and is sealed by heat sealing using the sealant layer. In addition, in order to implement | achieve such a heat seal, it is set as the structure by which the said sealant layer is located inside the soft-packing material 2. FIG. As shown in FIG. 3, two partial hole portions 222 are provided near both ends of the bottom gusset 221. In the vicinity of both ends of the bottom gusset 221, four folded portions of the soft wrapping material 2 are overlapped in the thickness direction. A through hole is provided in two of the four parts located on the inner side in the thickness direction. Through these through-holes, the two sealant layers located on the outer side in the thickness direction face each other and are joined. By providing the two partial hole portions 222, it is possible to prevent the vicinity of both ends of the bottom gusset 221 from being opened.

  The bonded portion 22 is a portion bonded to the base material 1 in the soft wrapping material 2. By providing the bonded portion 22, a housing space in which the base material 1 and the soft wrapping material 2 are sealed is configured. In the present embodiment, the entire peripheral portion on one end side in the longitudinal direction of the cylindrical soft packaging material 2 is joined to the base material 1. In particular, as shown in FIG. 7, the bonded portion 22 extends from the lower surface (back surface) of the extending portion 13 to the upper surface (front surface) of the extending portion 13 across the edge of the extending portion 13. It is joined to. This joining is performed by, for example, heat sealing using the sealant layer provided on the soft packaging material 2. The coating necessary for realizing this heat seal may be applied to the joint portion of the base material 1. The opening end 211 described above corresponds to a boundary portion between the bag portion 21 and the bonded portion 22. In addition, although it is preferable that the to-be-joined part 22 is joined to the front and back of the extension part 13 of the base material 1 from viewpoints, such as an improvement of joining strength, this invention is not limited to this. For example, the bonded portion 22 may be bonded only to the lower surface (back surface) of the extending portion 13 in the drawing.

  In the present embodiment, the covering material 12 is provided in a region that avoids the bonded portion 22 of the soft packaging material 2 that extends to the surface of the base material 11. That is, the bonded portion 22 is provided in the vicinity of the periphery of the base material 11, whereas the covering material 12 is provided in a region separated from the bonded portion 22 in the vicinity of the center of the base material 11. However, unlike this, the covering material 12 and the bonded portion 22 may be configured to overlap each other. In this case, the entire storage space for storing the contents Ct is surrounded by the soft packaging material 2 or the covering material 12. Thereby, the gas barrier property etc. of inner container A1 can be improved.

  The outer container C1 is used to accommodate the inner container A1 (that is, the inner container package D1) filled with the contents Ct. In the present embodiment, the outer container C1 includes a box part 3 and a lid part 4. ing.

  The box part 3 is a site | part which accommodates the inner container package D1, and is formed with a material harder than the soft packaging material 2 of the inner container A1. The material of the box part 3 is not particularly limited as long as the intended hardness can be realized, and examples thereof include polypropylene resin and polyethylene resin. The box portion 3 has a substantially rectangular shape in plan view corresponding to the substantially rectangular base material 1. However, the shape of the box portion 3 is not particularly limited, and may be a polygonal shape other than a rectangular shape, a circular shape, an elliptical shape, or the like. Moreover, although the shape corresponding to the shape of the base material 1 is preferable as the shape of the box part 3, if the inner container A1 can be accommodated and hold | maintained, the shape will not be specifically limited.

  A plurality of ribs 32 and claw portions 33 are formed on the inner surface of the box portion 3. Each of the plurality of ribs 32 has an elongated plate shape that stands up from the inner side surface, and extends in the depth direction of the box portion 3. The plurality of ribs 32 serve to improve the rigidity of the box portion 3 and constitute a plurality of engaging portions 31 together with the plurality of claw portions 33. In the present embodiment, the plurality of ribs 32 are arranged on the entire circumference of the inner surface of the box portion 3 at a predetermined interval. However, the arrangement of the plurality of ribs 32 is not limited to this, and any configuration may be employed as long as the rigidity of the box portion 3 is ensured and the portion appropriately functions as the engaging portion 31 described later. It may be provided in a partial area.

  The plurality of claw portions 33 are arranged on the opening side in the depth direction of the box portion 3 with respect to the plurality of ribs 32, and each protrudes from the inner side surface of the box portion 3. In the present embodiment, a total of six claw parts 33 are provided, including the three claw parts 33 shown in FIG. 2 and the three claw parts 33 hidden in the figure. Each claw portion 33 extends in a horizontal direction perpendicular to the depth direction of the box portion 3, and as shown in FIG. 9, there is a slight gap with respect to the rib 32 in the depth direction of the box portion 3. Is provided. As shown in the figure, the size of the gap is approximately the same as the thickness of the extended portion 13 of the base material 1, more specifically, the combined length of the extended portion 13 and the bonded portion 22. .

  In addition, the position in which the nail | claw part 33 is provided is not specifically limited, What is necessary is just the position which can hold | maintain the base material 1 of the inner container A1 appropriately. For example, four claw portions 33 may be provided at the four inner corners of the box portion 3. In this case, it is preferable that the nail | claw part 33 is a planar view L-shape.

  The cover part 4 is for taking the state which shielded the inner container package D1 from the outside, and the state exposed outside. Although the material of the cover part 4 is not specifically limited, For example, the molded article which consists of a linear low density polyethylene resin is used. In the present embodiment, the lid 4 is attached to the box 3 so as to be rotatable. In addition, when the covering material 12 is a thing which can be resealed, the airtightness of the cover part 4 is not so important, and the cover part 4 may not be provided depending on the case.

  As shown in FIG. 2, when the combined container package B1 is manufactured in the factory or when the purchaser purchases a new inner container A1 for refilling, the inner container is compared with the box 3 of the outer container C1. The package D1 is inserted. And as shown in FIG. 9, the extension part 13 of the base material 1 of the inner container A1 is sandwiched between the plurality of ribs 32 and the six claw parts 33 of the outer container C1. More specifically, not only the extending part 13 but also the joined part 22 joined to the extending part 13 is sandwiched between the rib 32 and the claw part 33. Thereby, as can be understood from FIG. 2, the base material 1 is fixed to the box portion 3 at a total of six locations, two on each long side and one on each short side. Thus, the rib 32 and the claw 33 that engage with the extending part 13 by supporting the extending part 13 by sandwiching the extending part 13 of the base material 1 constitute the engaging part 31.

  In addition, the engaging part 31 which consists of the rib 32 and the nail | claw part 33 is an example, and the structure of the engaging part 31 is not specifically limited. As long as the inner container A1 can be supported by engaging with the extending portion 13 extending outward from the bag portion 21 of the soft packaging material 2, the engaging portion 31 can take any configuration. For example, unlike the present embodiment, the engaging portion 31 may be configured by only the rib 32. In this case, the extended portion 13 of the base 1 of the inner container A1 is placed on the opening end side end of the rib 32, thereby realizing the engaged state between the extended portion 13 and the engaging portion 31. A1 (inner container package D1) can be held by the outer container C1.

  Next, the manufacturing method of inner container A1 is demonstrated. FIG. 10 shows a cylindrical film 2A used in an example of the method for producing the inner container A1. The tubular film 2 </ b> A is obtained by folding a long tubular film into a substantially strip shape. The material of the tubular film 2A is the same as the material of the soft packaging material 2 described above. The tubular film 2A in the folded state has two flat portions 21A and two gusset portions 22A. The two gusset portions 22A are portions where both sides in the width direction of the tubular film 2A are valley-folded. The two flat portions 21A are flat portions that connect the two gusset portions 22A. The cylindrical film 2 </ b> A having such a folded form is suitable for manufacturing the inner container A <b> 1 together with the substantially rectangular base material 1.

  Next, the folded tubular film 2A is expanded, and the table Tb is inserted from one side of the tubular film 2A as shown in FIG. The table Tb has a flat plate-like portion that can support the base material 1. This flat part is a site | part for prescribing | regulating the position of the base material 1 with respect to 2 A of cylindrical films. In the present embodiment, the table Tb is inserted so that the flat plate portion is positioned near the upper end of the tubular film 2A.

  Next, as shown in FIG. 12, the base material 1 is inserted into the cylindrical film 2A from above in the drawing. At this time, the base material 1 is one in which the base material 11 and the covering material 12 are already joined. The inserted base material 1 is placed on the flat plate-like portion of the table Tb.

  Next, as shown in FIG. 13, the peripheral portion of the base material 1 is pressed by the seal mold Md so as to be sandwiched by the vicinity of the upper end of the cylindrical film 2 </ b> A. The sealing mold Md is set to a temperature sufficient for the above-described sealant layer to exert a bonding force. Thereby, the vicinity of the upper end of the cylindrical film 2 </ b> A is heat-sealed to the peripheral portion of the base material 1. As a result, the extending portion 13 of the base material 1 and the bonded portion 22 of the soft packaging material 2 shown in FIGS. 2 to 7 are formed.

  Thereafter, the table Tb is withdrawn from the cylindrical film 2A, and the cylindrical film 2A is cut at a suitable position in the lower part of FIG. Thereby, the intermediate product comprised by 2 A of cut | disconnected cylindrical films and the base material 1 joined to this is obtained. Next, the intermediate product is turned upside down so that the cut portion of the tubular film 2A, that is, the opening portion is directed upward. The contents Ct are appropriately filled from the opening, and the opening of the tubular film 2A is heat-sealed. Thereby, the bottom gusset 221 shown in FIGS. 2 and 4 is formed, and the inner container A1 is completed.

  Next, operations of the combination container package B1, the inner container package D1, and the inner container A1 will be described.

  According to the present embodiment, as shown in FIGS. 8 and 9, the extending portion 13 extending from the bag portion 21 is supported by being engaged with the engaging portion 31 of the box portion 3 of the outer container C1. Yes. Along with this, the bag portion 21 of the inner container A <b> 1 is stably held in a fashion that hangs from the base material 1. Thereby, even if the soft packaging material 2 which comprises the bag part 21 consists of a comparatively soft material, and is filled with the indeterminate contents Ct, such as powder, the inner container package D1 is contained in the outer container C1. It can be held properly in a stable state.

  By forming the engaging portion 31 with the plurality of ribs 32 and the claw portions 33, the base material 1 of the inner container A1 can be easily and reliably sandwiched between the ribs 32 and the claw portions 33 of the extending portion 13 of the inner container A1. Can be held. Further, the plurality of ribs 32 extending in the depth direction are advantageous for increasing the rigidity of the box portion 3.

  Since the extending portion 13 is provided over the entire circumference of the opening end 211, the inner container A1 is disposed even when the claw portion 33 is provided in a position different from the position shown in FIG. Can be installed properly. Moreover, the effect which raises the rigidity of the base material 1 as a structural member holding the bag part 21 with which the content Ct was filled can be anticipated.

  Since the bonded portion 22 is bonded to the front and back surfaces of the base material 1, the soft packaging material 2 is unduly peeled from the base material 1 during the transportation, display, and use of the inner container A <b> 1. Etc. can be avoided. Moreover, also in the extension part 13, when the to-be-joined part 22 is joined to the front and back, the effect to reinforce the extension part 13 by the to-be-joined part 22 can be show | played.
