Description

  The present invention relates to a refill wrap film storage body and a bladeless storage box used therefor.

  Conventionally, a wrap film is generally used at the time of temporary storage or heat treatment of foods, processed products or seasonings, mainly in homes and restaurants. This type of wrap film is usually wound around the outer periphery of a paper cylindrical core to form a wound cylindrical body (wrapped wrap film), and is a paper rectangular parallelepiped storage provided with a cutting blade (cut blade). The thing (wrap film container) which accommodated the wound wrap film concerning a box is distribute | circulated and sold widely in the market.

  In recent years, demand for refills has increased as an approach to environmental problems. In particular, in the daily necessities field, customers are highly oriented toward environmental problems, and their demand is increasing year by year. For this reason, various proposals have been made for wrap film storage bodies and storage boxes for saving resources, reducing dust, improving handling at the time of disposal, and the like.

  For example, Patent Document 1 discloses a carton for storing a roll-shaped packaging material for refilling, in which the carton body can be stored in close contact with a roll-shaped packaging material-containing carton having a conventional cutting means. In addition, a roll-shaped packaging material storage carton for refilling is described.

  Patent Document 2 describes a tight package of a wound wrap film and a method for manufacturing the same.

JP 2005-112376 A Japanese Patent No. 3382687

  However, at present, wrap film refills (wrapping wrap films for refill) are sold by some manufacturers but are not mainstream in the market. The reason is considered to be that an effective means for stably supplying a wound wrap film for refilling to the market without losing its commercial value has not been established.

  In other words, wrap films occupying most of the wrapping film field for food packaging have functions such as film strength and cutability during use by performing stretching processing (generally uniaxial stretching or biaxial stretching) during film formation. Since it is raised, it has the property of tearing very easily. For this reason, the conventional refilled wrap film has a roll wrap film that moves axially in the storage box (packaging material) due to vibration during transportation and external pressure during display. ) Rubs against the inner wall of the storage box, so that there is a problem that scratches are easily generated, and various problems are caused by the scratches.

  Specifically, at the time of use after refilling (at the time of pulling out the wrap film), the wrap film is torn starting from the scratches and is torn off. In addition, when the wrap film is torn like this, it is easy for the user to lose sight of the end of winding of the wrap film, and subsequent drawing becomes difficult. Furthermore, when multiple wrapping with tearing of the wrap film described above is performed, it is no longer possible to pull out the wrap film completely (without tearing), and subsequent use is impossible. Can be in a bad state. In particular, the wound in the axial direction of the wound wrap film has a characteristic that it is easy to lose sight of the end of winding of the wrap film, and it is easy to induce a plurality of turns with the tear of the wrap film. Scratches that occur in the axial direction of the film are particularly problematic.

  On the other hand, as a base paper that constitutes the storage box of the wrapping film container for the purpose of saving resources and reducing waste, as well as facilitating volume reduction (crushing, collapsing, etc.) during disposal and improving handling. It is conceivable to use a thin, low-strength base paper. However, this type of wrap film container is normally distributed in the market in the form of a stack of cardboards packed in a bundled state of a plurality of wrap film containers during transportation in the axial direction of the wound wrap film. The At this time, a load of about 3 to 10 kg is applied to the wrap film storage body packed in the lowermost cardboard. Therefore, when a storage box is configured using thin, low-strength base paper, the strength (rigidity) of the box becomes insufficient, and the storage box packed in the bottom cardboard is crushed and deformed. At the same time, it becomes difficult to pull out the wrap film, and as a result, the commercial value is greatly impaired. Furthermore, if the box has insufficient rigidity, the handling at the time of operations such as packing, stacking, transportation and display is also deteriorated. In order to avoid such problems, the current product with a cutting blade (non-refillable product) is designed to form a storage box using thick, high-strength base paper and to give strength to the storage box itself. I was forced to adopt. Therefore, in order to enable packing, transportation and display equivalent to the current product (non-refillable product) in the refill wrap film container, it is thick and high strength like the current product (non-refillable product). As a result, it has been difficult to save resources and improve handling by adopting a thin, low-strength base paper.

  Note that Patent Document 1 describes that refilling is easy and can be used over and over again, which is useful for resource reduction. However, the technique of Patent Document 1 does not have a function of preventing the wound wrap film from being damaged by vibration during transportation. Therefore, it is difficult to stably supply the wound wrap film for refilling to the market without impairing the commercial value. In addition, environmental problems such as resource saving, waste reduction, and volume reduction at the time of disposal are insufficient.

  Further, the above-mentioned Patent Document 2 describes that by adopting shrink wrapping, it is possible to easily and surely pull out the wrap film from the end of winding, so that it is possible to stably supply a wound film for refilling. Has been. However, in the technique of Patent Document 2, since the wound wrap film is simply formed by shrink wrapping, the wrapping film may be broken during transportation or the like, and the wrap film is easily damaged by external pressure. Furthermore, in such a form, packing, transportation, and display equivalent to the current product (non-refillable product) cannot be performed, for example, stacking cannot be performed during transportation or display. And since shrink packaging is employ | adopted, there exists a possibility that the heat applied at the time of shrink packaging may influence a wrap film not a little.

  The present invention has been made in view of such circumstances, and its purpose is to stably supply a wound wrap film for refilling to the market without greatly impairing its commercial value, Refillable wrap film container that can handle almost the same as current products (non-refillable products) while addressing environmental issues such as resource saving, waste reduction, and easy volume reduction at disposal, and bladeless storage used for this To provide a box.

(First embodiment)
FIG. 1 is a schematic perspective view showing a refill wrap film container 1 of the first embodiment.
The refill wrap film storage body 1 of the present embodiment includes a wound wrap film 11 and a bladeless storage box 31 for storing the wound wrap film 11.

  The wound wrap film 11 is obtained by winding (wrapping) a predetermined number of wrap films 13 around an outer periphery 12a of a cylindrical core body 12 made of paper or plastic. The axial length S (mm) of the cylindrical core 12 is S−1.0 ≦ W ≦ S with respect to the minimum value W (mm) of the inner dimension in the longitudinal direction of the bladeless storage box 31 as will be described later. It is set to satisfy the relationship. The wound wrap film 11 is stored in the bladeless storage box 31 so that the axial direction of the wound wrap film 11 coincides with the longitudinal direction of the bladeless storage box 31 as shown in the figure.

FIG. 2 is a schematic perspective view showing the bladeless storage box 31 of the present embodiment.
The bladeless storage box 31 is a packaging material used when packing, transporting, displaying, selling, and storing the rewinding wound wrap film 11, and at least one base paper 32 is formed into a plurality of folding lines 32a. It is composed of a folded box that is bent along the outer shape and formed into a substantially columnar shape. As illustrated, the bladeless storage box 31 of the present embodiment includes a storage portion 33 having an opening 33a on the upper surface and a lid portion 38 that closes the opening 33a.

  Examples of the base paper 32 constituting the bladeless storage box 31 include cardboard, coated cardboard, single-sided cardboard, cardboard, and the like. However, the base paper 32 is not particularly limited, and paper known in the industry is appropriately selected. Can be used. The base paper 32 may be obtained by embossing, printing, laminating using polyethylene or the like on these materials.

Here, the base paper 32 has a basis weight (weight per 1 m ^{2 of the} base paper) in the range of 150 to 480 g / m ² from the viewpoint of saving resources and reducing dust and ensuring the required strength (rigidity). It is required to be within. Within this range, the shape required for the storage box can be maintained, the product can be securely protected by impact or dropping during transportation, etc., and can be easily displayed at the store. Volume reduction (disintegration, collapse, etc.) at the time of disposal can be easily performed. On the other hand, when the basis weight exceeds 480 g / m ² , there is almost no difference from the base paper used in the current product (non-refillable product) with a cutting blade, and the effect of resource saving and dust reduction is poor. In addition, it is not expected to improve the handling property, such as the volume cannot be easily reduced at the time of disposal. On the other hand, if the basis weight is less than 150 g / m ² , the required strength cannot be maintained, it becomes difficult to reliably maintain the shape and protect the product, and the effect of improving the handleability is poor. Become. From these viewpoints, the basis weight is preferably in the range of 180~410g / m ^2, and more preferably in the range of 210~350g / m ^2.

FIG. 3 is a schematic plan view showing a developed view (base paper 32) of the bladeless storage box 31 of the present embodiment.
The bladeless storage box 31 has a front plate 34, a bottom plate 35, and a fold line 32a on the support piece 34a and a folded piece 34b and a pair of insertion pieces 34c, 34d connected to the support piece 34a via a fold line 32a. The first side plates 35a, 35b, the rear plate 36, and the second side plates 36a, 36b, the top plate 39, and the top plate 39, which are connected to each other via the folding line 32a, are connected to each other via the folding line 32a. The base paper 32 includes third side plates 39a and 39b, a lid cover piece 40, fourth side plates 40a and 40b connected to the lid piece 40 via a folding line 32a, and an opening piece 41. Here, the front plate 34, the bottom plate 35, the rear plate 36, the top plate 39, and the lid cover piece 40 are connected in this order via a folding line 32a as shown in the figure. On the other hand, the unsealing piece 41 is connected to the lid cover piece 40 via the cut line 41a.

  Here, in the present embodiment, the length in the longitudinal direction of the rear plate 36, that is, the distance between the folding lines 32 a in the longitudinal direction of the rear plate 36 is the minimum value W of the inner dimension in the longitudinal direction of the bladeless storage box 31. (Mm) is set. That is, the length in the longitudinal direction of the rear plate 36 is set shorter than the length in the longitudinal direction of the front plate 34, the bottom plate 35, the top plate 39, and the lid cover piece 40 (distance between the folding lines 32a in the respective longitudinal directions). Has been. Further, the longitudinal lengths of the front plate 34, the bottom plate 35, the top plate 39, the lid piece 40, and the opening piece 41, that is, the distance between the respective folding lines 32a in the longitudinal direction are determined by the length of the cylindrical core body 12 to be stored. It is set larger than the shaft length S (mm) (see illustration).

  Further, the height of the front plate 34, more specifically, the height t1 of the support piece 34a constituting the front plate 34 and the height t2 of the folded piece 34b are set to a fold line 32a at the boundary between the rear plate 36 and the top plate 39. On the other hand, the rear plate 36 is formed lower than the height t3. These relationships are not particularly limited as long as the height of the front plate 34 is lower than the height of the rear plate 36 with respect to the fold line 32a at the boundary between the rear plate 36 and the top plate 39. When the height t3 is set to 45 mm, the heights t1 and t2 of the support piece 34a and the folded piece 34b are preferably 5 mm or more, more preferably in the range of 10 to 40 mm or less, and even more preferably 17 It is the range of -37 mm or less.

  By folding the base paper 32 along folding lines 32a formed at a plurality of locations, a bladeless storage box 31 having a substantially rectangular parallelepiped shape having the storage portion 33 and the lid portion 38 is formed (FIG. 1). And FIG. 2).

  The storage portion 33 is formed from a front plate 34, a bottom plate 35, a rear plate 36, side plates 35a, 35b, 36a, 36b, a support piece 34a, a folded piece 34b, and insertion pieces 34c, 34d. That is, the folded piece 34b of the front plate 34 is folded 180 degrees along the fold line 32a and overlapped with the support piece 34a, and the front plate 34, the bottom plate 35, the rear plate 36, and the side plates 35a, 35b, 36a, 36b A bottomed box-shaped storage portion opened on the top surface by being bent substantially vertically along the fold line 32a and inserting the insertion pieces 34c, 34d of the front plate 34 into the gap between the side plates 35a, 35b and the side plates 36a, 36b. 33 is formed (see illustration).

  The lid portion 38 is formed from a top plate 39, a lid lid piece 40, an opening piece 41, and side plates 39a, 39b, 40a, 40b. That is, the top plate 39, the lid cover piece 40, and the side plates 39a, 39b, 40a, 40b are bent substantially vertically along the plurality of fold lines 32a, whereby the lid portion 38 having a shape corresponding to the opening portion 33a of the storage portion 33 is obtained. Molded (see illustration).

FIG. 4 is a schematic cross-sectional view showing the main part of the refill wrap film storage body 1 (the state in which the wound wrap film 11 is stored in the bladeless storage box 31) of the present embodiment.
The refill wrap film storage body 1 of the present embodiment stores the wound wrap film 11 in the storage portion 33 of the bladeless storage box 31 and then uses the folding line 32a between the rear plate 36 and the top plate 39 as a base point. The lid portion 38 is tilted to close the opening portion 33 a of the storage portion 33, and the opening piece 41 is adhered to the outer wall of the front plate 34. Here, as described above, the bladeless storage box 31 has the minimum inner dimension W (mm) in the longitudinal direction, that is, the length in the longitudinal direction of the rear plate 36 (between the folding lines 32a in the longitudinal direction of the rear plate 36). The distance) is set so as to satisfy the relationship of S−1.0 ≦ W ≦ S with respect to the axial length S (mm) of the cylindrical core body 12 stored in the storage unit 33. Therefore, when the wound wrap film 11 is stored in the storage portion 33, the side plates 36a and 36b are partially curved so as to conform to the axial length S (mm) of the cylindrical core body 12. Therefore, the wound wrap film 11 is stored in the storage portion 33 in a state in which at least a part of the side plates 36a and 36b is curved outwardly, whereby the cylindrical core 12 is axially moved. Are housed in the bladeless storage box 31 with substantially no gap (see FIG. 4). That is, in this embodiment, the wound wrap film 11 is loosely between the side plates 36a and 36b (between the side plate 35a, the side plate 36a and the insertion piece 34c, and the side plate 35b, the side plate 36b and the insertion piece 34d). It is stored in the bladeless storage box 31 in a sandwiched state (see FIG. 4).

  And the opening of the refill wrap film container 1 of the present embodiment is usually cut along the cut line 41a of the opening piece 41 of the lid portion 38, the opening piece 41 on the support piece 34a is removed, and this state Then, the lid cover piece 40 is separated from the outer wall of the front plate 34, and the lid portion 38 is tilted toward the rear plate 36 with the fold line 32a between the rear plate 36 and the top plate 39 as a base point. Thereafter, the wound wrap film 11 is taken out from the opening 33a of the storage portion 33 of the refill wrap film storage body 1 opened in this manner.

  Now, in the refill wrap film container 1 of the present embodiment, as described above, the minimum value W (mm) of the inner dimension in the longitudinal direction of the bladeless storage box 31 is the axial length S ( mm), the cylindrical core body 12 is stored in the bladeless storage box 31 with substantially no gap in the axial direction. Therefore, the movement of the wound wrap film 11 in the bladeless storage box 31, in particular, the movement in the axial direction is restricted. As a result, the bladeless storage box 31 and the wrap film (on the outermost periphery of the wound wrap film 11) 13 is prevented, and the occurrence of trauma such as scratches, creases, cuts and tears of the wrap film 13 is suppressed. Therefore, according to the refill wrap film container 1, the wound wrap film 11 for refill can be stably supplied to the market without greatly impairing the commercial value. In addition, in the current product (non-refillable product) with a cutting blade, the fact that a clearance of about +2 mm is set in order to facilitate the drawing of the wrap film from the wound wrap film (the length of the storage box) In view of the fact that the minimum value of the inner dimension in the direction is about +2 mm with respect to the axial length of the cylindrical core body, it can be said that the design concept of this embodiment is different.

  Moreover, in the refill wrap film container 1 of the present embodiment, the shape stability (shape retention) of the bladeless storage box 31 is enhanced. This is because the cylindrical core body 12 is accommodated in the bladeless storage box 31 substantially without any gap in the axial direction, and the side walls (side plates 35a, 35b, 36a, 36b, side plates 39a, This is because 39b, 40a, and 40b) are supported by the hard and strong cylindrical core body 12. Therefore, although the refill wrap film container 1 of the present embodiment uses a base paper 32 that is thinner and lower in strength than conventional ones, it can be stably handled in packaging, stacking, transportation, display, and the like. It becomes possible.

  Furthermore, in the refill wrap film storage body 1 of the present embodiment, the cylindrical core body 12 is stored in the bladeless storage box 31 with substantially no gap in the axial direction, and thus is added at the time of stacking described above. The load can be received by the hard and strong cylindrical core body 12. Therefore, the crushing and deformation of the bladeless storage box 31, the occurrence of breakage and damage of the wrap film 13 accompanying this, and the occurrence of defective drawing of the wrap film 13 accompanying these are effectively suppressed. Therefore, the refill wrap film container 1 of the present embodiment can perform packing, stacking, transportation, display, and the like substantially the same as the current product (non-refill product).

Moreover, in the refill wrap film container 1 of the present embodiment, the bladeless storage box 31 is configured from the base paper 32 having a basis weight (weight per 1 m ^{2 of} base paper) in the range of 150 to 480 g / m ^2. Therefore, resource saving and waste reduction can be achieved, and volume reduction at the time of disposal can be easily performed.

  On the other hand, in the refill wrap film container 1 of the present embodiment, the heights t1 and t2 of the support piece 34a and the folded piece 34b constituting the front plate 34 are formed lower than the height t3 of the rear plate 36. Therefore, when the refill wrap film container 1 is opened, the wide and ergonomically open portion 33a is exposed. Therefore, the visibility of the wound wrap film 11 after opening is enhanced, and the winding wrap film 11 can be taken out very easily. That is, by adopting a configuration in which the height of the front plate 34 is lower than the height of the rear plate 36, the wound wrap film 11 in the bladeless storage box 31 can be easily taken out. Improve. Thus, the configuration in which the height of the front plate 34 is lower than the height of the rear plate 36 is important for realizing a three-dimensional and wide opening 33a, and it is ergonomically and naturally wound. It is considered that the design is optimal for taking out the wrap film 11 times.

Moreover, in the refill wrap film housing 1 of the present embodiment, when the wound wrap film 11 is taken out, the front plate 34 is tilted outward from the fold line 32, that is, by being tilted, thereby opening the opening portion. 33a can be expanded. In addition, since the base paper 32 having a basis weight (weight per 1 m ^{2 of the} base paper) in the range of 150 to 480 g / m ² is used, the base paper 32 is easily bent when the wound wrap film 11 is taken out. Thus, the opening 33a can be deformed. By expanding and / or deforming the opening 33a in this way, a space for putting a finger into the bladeless storage box 31 for gripping the wound wrap film 11 is provided, and the wound wrap film can be operated more naturally. 11 can be taken out. Therefore, it becomes easier to take out the wound wrap film 11 in the bladeless storage box 31 ergonomically. Furthermore, since it is possible to suppress the contact between the wrap film 13 (outermost circumference of the wound wrap film 11) and the bladeless storage box 31 at the time of take-out, the wrap film 13 is accompanied by scratches, creases, cuts, tears. Prevention of the occurrence of such trauma is also expected.

FIG. 5 is a schematic perspective view showing the bladeless storage box 61 of the second embodiment.
The bladeless storage box 61 is a packaging material used when packing, transporting, displaying, selling, and storing the wound wrap film 11 for refilling, like the bladeless storage box 31 of the first embodiment described above. In this case, at least one base paper 62 is folded along a plurality of folding lines 62a and formed into a substantially box-shaped outer shape box. As illustrated, the bladeless storage box 61 of the present embodiment has a storage portion 63 having an opening 63a on the upper surface and a lid portion 68 that closes the opening 63a. In addition, the raw material and basic weight of the base paper 62 which comprise the bladeless storage box 61 are the same as the base paper 32 of 1st Embodiment mentioned above, and the overlapping description is abbreviate | omitted.

The first side plates 65a and 65b, the rear plate 66, and the second side plates 66a and 66b, the top plate 69, and the top plate 69, which are connected to each other via the folding line 62a, are connected to each other via the folding line 62a. The base paper 62 includes third side plates 69 a and 69 b, a lid cover piece 70, fourth side plates 70 a and 70 b connected to the lid piece 70 via a folding line 62 a, and an opening piece 71. Here, the front plate 64, the bottom plate 65, the rear plate 66, the top plate 69, and the lid cover piece 70 are connected in this order via a folding line 62a as shown in the figure. On the other hand, the opening piece 71 is connected with the lid cover piece 70 via the cut line 71a.

  Here, in this embodiment, the length in the longitudinal direction of the support piece 64a on the front plate, that is, the distance between the fold lines 62a in the longitudinal direction of the support piece 64a on the front plate is the length in the longitudinal direction of the bladeless storage box 61. The minimum value W (mm) of the inner dimension is set. That is, the length of the front plate support piece 64a in the longitudinal direction is longer than the lengths of the bottom plate 65, the rear plate 66, the top plate 69, and the lid piece 70 (the distance between the respective folding lines 62a in the longitudinal direction). Is also set short. Therefore, the length in the longitudinal direction of the bottom plate 65, the top plate 69, the rear plate 66, the lid piece 70, and the opening piece 71, that is, the distance between the respective folding lines 62a in the longitudinal direction is the length of the cylindrical core body 12 to be stored. It is set to be equal to or larger than the shaft length S (mm) (see illustration).

  Further, the height of the front plate 64, more specifically, the height t4 of the support piece 64a constituting the front plate 64 and the height t5 of the folded piece 64b are set to the folding line 62a at the boundary between the rear plate 66 and the top plate 69. On the other hand, it is formed lower than the height t6 of the rear plate 66. These relationships are the same as those in the first embodiment described above, and redundant descriptions are omitted.

  The above-mentioned base paper 62 is bent along folding lines 62a formed at a plurality of locations, thereby forming a bladeless storage box 61 having a substantially rectangular parallelepiped shape having the above-described storage portion 63 and lid portion 68 (FIG. 5). reference).

  The storage portion 63 is formed from a front plate 64, a bottom plate 65, a rear plate 66, side plates 65a, 65b, 66a, 66b, a support piece 64a, a folded piece 64b, and insertion pieces 64c, 64d. That is, the folded piece 64b of the front plate 64 is folded 180 degrees along the fold line 62a and overlapped with the support piece 64a, and the front plate 64, the bottom plate 65, the rear plate 66, and the side plates 65a, 65b, 66a, 66b are arranged in a plurality. By folding the fold line 62a substantially vertically, a bottomed box-shaped storage portion 63 having an open top surface is formed (see the drawing). In the present embodiment, the insertion pieces 64c and 64d of the front plate 64 are inserted inside the side plates 65a and 65b.

  The lid 68 is formed from a top plate 69, a lid lid piece 70, an opening piece 71, and side plates 69a, 69b, 70a, 70b. That is, the top 68, the lid piece 70, and the side plates 69a, 69b, 70a, 70b are bent substantially vertically along the plurality of fold lines 62a, so that the lid 68 having a shape corresponding to the opening 63a of the storage 63 is obtained. Molded.

FIG. 7 is a schematic cross-sectional view showing a main part in a state where the wound wrap film 11 is stored in the bladeless storage box 61 of the present embodiment.
In this embodiment, the wound wrap film 11 is stored in the storage portion 63 of the bladeless storage box 61 while being held between the insertion pieces 64c and 64d of the front plate 64 (see the drawing). That is, the insertion pieces 64c and 64d are inserted so as to be located inside the side plates 65a and 65b. Then, the lid 68 is tilted around the folding line 62 a between the rear plate 66 and the top plate 69 to close the opening 63 a of the storage portion 63, and the opening piece 71 is bonded to the outer wall of the front plate 64. Here, as described above, the bladeless storage box 61 has the minimum inner dimension W (mm) in the longitudinal direction, that is, the longitudinal length of the front plate support piece 64a (the longitudinal direction of the front plate support piece 64a). The distance between the fold lines 62a is set so as to satisfy the relationship of S−1.0 ≦ W ≦ S with respect to the axial length S (mm) of the cylindrical core body 12 stored in the storage portion 63. ing. Therefore, when the wound wrap film 11 is stored in the storage portion 63, the side plates 64c and 64d are partially curved so as to conform to the axial length S (mm) of the cylindrical core body 12. Therefore, the wound wrap film 11 is housed in the housing portion 63 in a state in which at least a part of the side plates 64c and 64d is curved outwardly so that the cylindrical core body 12 is axially moved. Are housed in the bladeless storage box 61b with substantially no gap (see FIG. 7). That is, in the present embodiment, the wound wrap film 11 is gently placed between the insertion pieces 64c and 64d (between the insertion piece 64c, the side plates 65a and 66a and the insertion piece 64d, the side plate 65b and the side plate 66b). It is stored in the bladeless storage box 61b in a sandwiched state (see FIG. 7).

  Then, the bladeless storage box 61 of the present embodiment is normally opened by cutting along the cut line 71a of the opening piece 71 of the lid 68, removing the opening piece 71 on the folded piece 64a, and in this state the lid lid This is done by separating the piece 70 from the outer wall of the front plate 64 and tilting the lid 68 toward the rear plate 66 with the fold line 62a between the rear plate 66 and the top plate 69 as a base point. And the wound wrap film 11 is taken out from the opening part 63a of the storage part 63 of the bladeless storage box 61 opened in this way.

In the present embodiment, as described above, the minimum value W (mm) of the inner dimension in the longitudinal direction of the bladeless storage box 61 is S-1. It is set to satisfy the relationship of 0 ≦ W ≦ S, and the cylindrical core body 12 is stored in the bladeless storage box 61 with substantially no gap in the axial direction. Further, the bladeless storage box 61 is constituted by the base paper 62 having a basis weight (weight per 1 m ^{2 of the} base paper) in the range of 150 to 480 g / m ² . Further, the heights t4 and t5 of the support piece 64a and the folding piece 64b constituting the front plate 64 are formed lower than the height t6 of the rear plate 66, and the front plate 64 is removed along the folding line 62. The opening 63a can be expanded by tilting in the direction, i.e., tilting. Therefore, the same effect as the first embodiment described above is exhibited.

  In addition, in the bladeless storage box 61 of the present embodiment, the insertion pieces 64c and 64d are connected to the front plate 64, and the front plate 64 is tilted outward with the folding line 62a as a base point. The insertion pieces 64c and 64d are displaced outward from the bladeless storage box 61. Therefore, the wound wrap film 11 sandwiched between the insertion pieces 64c and 64d is guided to the so-called insertion pieces 64c and 64d as the front plate 64 is tilted and the insertion pieces 64c and 64d are displaced. While being done, it moves to the outside of the bladeless storage box 61. The bladeless storage box 61 has a mechanism for moving the wound wrap film 11 to the outside of the bladeless storage box 61, so that the wound wrap film 11 can be gripped when the wound wrap film 11 is taken out. A wide space can be secured, and the wound wrap film 11 can be grasped and taken out by a more natural and smooth operation. Therefore, it is ergonomically easy to take out the wound wrap film 11 from the bladeless storage box 61, and the usability is greatly improved.

  The above embodiment is an example for explaining the present invention, and the present invention is not limited only to the embodiment, and the present invention can be variously modified without departing from the gist thereof. Is possible.

  For example, in the above-described embodiment, the bladeless storage boxes 31 and 61 having the storage portions 33 and 63 and the lid portions 38 and 68 are illustrated, but the bladeless storage boxes 31 and 61 are, for example, only from the storage portions 33 and 63. Alternatively, the storage units 33 and 63 and the lids 38 and 68 may be individually separated.

  Further, a part or all of the side plates 35a and 35b and the side plates 36a and 36b, or between the side plates 65a and 65b and the side plates 66a and 66b may be bonded using an adhesive or the like. Further, such adhesion may be in a state where it can be easily dissociated or in a state where it cannot be dissociated.

  Further, in the above embodiment, the opening pieces 41 and 71 bonded to the outer walls of the front plates 34 and 64 are cut along the cut lines 41a and 71a, and the opening pieces 41 on the support pieces 34a or the folded pieces 64b are formed. , 71 is removed, and the opening form in which the lid pieces 40, 70 are separated from the outer walls of the front plates 34, 64 in this state is illustrated, but other known methods may be employed. That is, instead of opening the zipper in the axial direction of the wound wrap film 11 as in the above embodiment, the zipper may be opened in the circumferential direction of the wound wrap film 11, for example. Further, for example, the front plate 34 and the lid cover piece 40 may be formed so as to be fitted with male and female, and may be opened by releasing the fitting. Alternatively, for example, the front plate 64 and the lid cover piece 70 may be locked with an adhesive or a tape, and may be opened by releasing the locking. In the above, the front plates 34 and 64 and the lid cover pieces 40 and 70 may be overlapped and overlapped.

  Further, in the above-described embodiment, the front plates 34 and 64 are illustrated as being formed so as to be movable outwardly from the folding lines 32a and 62a. However, for example, the insertion pieces 34c, 34d, 64c, and 64d are illustrated. May be bonded to the side plates 35a, 35b, 36a, 36b, 65a, 65b, 66a, 66b and the like. If comprised in this way, since the fall of the front plates 34 and 64 will be controlled, the shape stability (shape retainability) of the bladeless storage boxes 31 and 61, particularly the storage portions 33 and 63, is enhanced. Even when such a configuration is adopted in which the tilting of the front plates 34, 64 is restricted, the insertion pieces 34c, 34d, 64c, 64d and the side plates 35a, 35b, 36a, 36b, 65a, 65b are used. , 66a, 66b, the front plates 34, 64 can be tilted outward from the folding lines 32a, 64a when the bladeless storage boxes 31, 61 are opened. Alternatively, if the front plates 34 and 64 are connected to the insertion pieces 34c, 34d, 64c, and 64d through perforations or the like, the front plates 34 and 64 can be folded only by breaking the perforations. It can be freely tilted outward from the lines 32a and 62a.

  The refill wrap film container and the bladeless storage box of the present invention can stably provide a refill wrap film corresponding to environmental problems such as resource saving, dust reduction, and easy volume reduction at the time of disposal, Moreover, since it can be handled in the same manner as current products (non-refillable products), it can be used widely and effectively in general wrap films for food or daily use.
