Description

  The present invention relates to a packaging medium storage container that stores a packaging medium wound body in which the packaging medium is wound in a cylindrical shape, and particularly when the packaging medium is pulled out from the packaging medium storage container, the packaging medium is contained in the packaging medium storage container. The present invention relates to a packaging medium storage container that can prevent rewinding.

  As shown in FIG. 4A, a conventional packaging medium supply tool 101 includes a packaging medium wound body 102 (hereinafter appropriately referred to as a wound body 102) and a packaging medium storage container 103 (in which the wound body 102 is accommodated). Hereinafter, the storage container 103) is appropriately included. The wound body 102 is formed by winding a packaging medium 112 used for food packaging or the like around a cylindrical winding core (not shown in the drawing). The wound body 102 is stored in a paper storage container 103 having an elongated rectangular parallelepiped shape.

  The storage container 103 is formed so as to cover a cover body 115 having an opening 130 that opens over the entire surface in the upper part of the drawing, and covers the opening 130, and one end of the storage container 103 is attached to the container body 115. And a cover plate 122 connected to be rotatable.

  The container body 115 includes a bottom plate 104, a front plate 105, and a rear plate 106. The storage container 103 includes a lid front plate 123 erected on the lid plate 122, and overlaps the front plate 105 when the lid plate 122 closes the opening 130. A cutter 124 is formed on one end 146 of the front lid plate 123 that faces one end 140 where the front lid plate 123 is connected to the lid plate 122.

  In the central portion of the front plate 105 in the longitudinal direction X, a packaging medium holding portion 126 (hereinafter, appropriately holding portion 126) (FIG. 4C) for holding the leading end of the packaging medium 112 is formed (Patent Literature). 1). A sub front plate 107 is connected to the front plate 105 at a second connecting side 139, and the sub front plate 107 is attached to the back side of the front plate 105. The sub front plate 107 has a holding plate 109 which is a part of the sub front plate 107. The holding plate 109 is rotated around the second connecting side 139 from the state of being bonded to the back side of the front plate 105 at the start of use, and is cut and raised at an angle α (FIG. 4B), and the opening 130 side (See, for example, Patent Document 2).

  When using the packaging medium 112, hold the storage container 103 in the hand, open the cover plate 122, grasp and pull out the packaging medium 112, the wound body 102 rotates in the storage container 103, and winds the packaging medium 112. It can be peeled from the rotating body 102 and pulled out of the storage container 103. After the required length of the packaging medium 112 is pulled out, the lid plate 122 is closed, the center in the longitudinal direction X of the lid front plate 123 is pressed with the thumb of the hand opposite to the hand from which the packaging medium 112 was pulled out, and the cutter 124 is pressed. The packaging medium 112 is cut by use, and the separated packaging medium 112 is used. After the packaging medium 112 is pulled out of the storage container 103 and cut by the cutter 124, the packaging medium 112 is held by the holding unit 126, but when the packaging medium 112 tries to return into the storage container 103, it tries to return. The movement of the wrapping medium 112 is restricted by the restraining plate 109, so that it is difficult to return into the storage container 103.

JP-A-63-55043 (FIG. 1 etc.) JP-A-5-229551 (FIG. 1 etc.)

  However, when pulling out the packaging medium 112 from the container main body 115, in many cases, the user pulls the tip of the packaging medium 112 at the center in the longitudinal direction X with a finger. At that time, if a strong tension is applied to the central portion of the packaging medium 112 and the restraining plate 109 exists in the central portion inside the storage container 103 in an excessively cut and raised shape, the packaging medium 112 is caught on the restraining plate 109. was there.

  Further, since the holding portion 126 that holds the packaging medium 112 is often provided near the center of the front plate 105 in the longitudinal direction X, the trouble that the packaging medium 112 returns into the storage container 103 is caused by the longitudinal direction of the front plate 105. Often occurs at the end of X. For this reason, it has been desired that the holding plate 109 is provided at a portion other than the central portion in the longitudinal direction X to prevent the return of the packaging medium. Further, the cut-and-raised holding plate 109 may not rise sufficiently or may have an unstable rising angle, and the return of the drawn packaging medium 112 may not be sufficiently restricted.

  Therefore, the present invention does not provide resistance when the packaging medium is pulled out from the storage container, and on the other hand, the movement of the packaging medium to return into the storage container is sufficiently restricted even at a portion other than the central portion of the storage container. An object of the present invention is to provide a packaging medium storage container having a holding plate that can be used.

In order to achieve the above object, the packaging medium storage container 3 according to the first aspect of the present invention is an elongated packaging medium winding in which the packaging medium 12 is wound into a cylindrical shape in FIGS. A packaging medium storage container 3 for storing the body 2 and having an opening 30 on one side; a bottom plate 4 facing the opening 30; a front plate 5 erected on one side 31 of the bottom plate 4; A rear plate 6 erected on the other side 32 of the bottom plate 4 facing the side 31; a first connecting side 38 facing the other side 32 of the bottom plate 4; A lid plate 22 rotatably connected to the plate 6 and configured to close the opening 30; a second connecting side 39 facing one side 31 of the bottom plate 4; A sub front plate 7 connected to the front plate 5; the sub front plate 7 forms an angle (90 degrees -α ) with respect to the opening 30. And it has two holding plate 9 arranged so as to protrude into the opening 30 side; angle (90 ° - alpha) is located at the corner of the inclined towards the bottom plate 4 with respect to the opening 30; retainer plate The outer peripheral line 16 of the protruding portion 9 has a start point 17 that is closest to the midpoint 19 of the second connection side 39, and the start point 17 is located away from the second connection side 39. The end point 18 is the farthest point from the end point 18, and the end point 18 is on the second connecting side 39.

  With this configuration, the outer peripheral lines of the protruding portions of the two holding plates start from the point closest to the midpoint of the second connecting side, and the starting point is located away from the second connecting side. Yes, since the end point is the point farthest from the middle point of the second connecting side, and the end point is on the second connecting side, the rise of the portion near the starting point of the two holding plates is suppressed. The part near the end point rises at an angle larger than the part near the start point without being restrained from rising, and the two restraining plates prevent the packaging medium drawn from the packaging medium storage container from returning to the packaging medium storage container. It can be stably prevented.

  The packaging medium storage container 3 according to the second aspect of the present invention is, for example, as shown in FIGS. 1 and 2, in the packaging medium storage container of the first aspect, the outer peripheral line 16 has a portion close to the starting point 17. As the distance from the start point 17 increases, the distance W from the second connection side 39 is gradually increased. As the distance from the end point 18 increases, the distance W from the second connection side 39 approaches the start point 17. It is configured to increase rapidly compared to the increase in part.

  If comprised in this way, as for the outer periphery of each of the two holding plates, the portion near the start point gradually increases the distance from the second connecting side as the distance from the start point increases, and the portion near the end point increases from the end point. As the distance W from the second connecting edge increases with increasing distance compared to the increase in the portion close to the starting point, the wrapping medium drawn out from the wrapping medium storage container has two portions close to the starting point. It is difficult to contact the holding plate, and even when it comes into contact, the resistance caused by rubbing between the two holding plates and the packaging medium can be kept low. In the portion close to the end point, due to the rapid increase in the distance W, the two restraining plates that sufficiently restrict the movement of the packaging medium to return into the packaging medium storage container are sufficiently performed.

  For example, as shown in FIG. 1, the packaging medium storage container 3 according to the third aspect of the present invention has a surface 25 in which two holding plates 9 pass through the midpoint 19 of the second connecting side 39 and are perpendicular to the bottom plate 4. With respect to the plane.

  If comprised in this way, since two restraining plates are arrange | positioned in plane symmetry with respect to the surface which passes through the middle point of the 2nd connection side, and is perpendicular to a bottom plate, contact with the restraining plate of a packaging medium is prevented, and packaging media The return to the packaging medium storage container can be stably prevented by the two holding plates.

  To achieve the above object, a packaging medium supply tool 1 according to a fourth aspect of the present invention is a packaging medium according to any one of the first to third aspects as shown in FIG. A storage container 3; and a packaging medium roll 2 in which the packaging medium 12 is wound in a cylindrical shape.

  As described above, according to the packaging medium storage container of the present invention, the outer peripheral lines of the protruding portions of the two holding plates start from the point closest to the midpoint of the second connecting side, and the start point Are located away from the second connecting side, and the end point is the point farthest from the middle point of the second connecting side, and the end point is on the second connecting side. The portion near the starting point of the wrapping material is restrained from rising, the portion near the ending point is not restrained from rising and rises at a larger angle than the portion near the starting point, and the wrapping medium drawn from the wrapping medium container is the wrapping medium. Returning to the storage container can be stably prevented by the two holding plates.

  With reference to FIGS. 1-3, the structure of the packaging medium supply tool 1 (henceforth appropriate supply tool 1) provided with the packaging medium storage container 3 (henceforth appropriate storage container 3) of embodiment of this invention. Will be explained. FIG. 1 is a perspective view of the supply tool 1 in a horizontally disposed state. FIG. 2 is a perspective view of the container main body 15 in which the lid plate 22 and the lid front plate 23 of the storage container 3 of FIG. 1 and the packaging medium winding body 2 (hereinafter appropriately referred to as the winding body 2) are omitted. FIG. 3 is a cross-sectional view in which the wound body 2 is omitted in the direction perpendicular to the longitudinal direction X in the longitudinal center portion of the storage container 3 of FIG. 1 and 3, the cover plate 22 is in an open state.

  The supply tool 1 includes a wound body 2 and a storage container 3 that houses the wound body 2. The wound body 2 is a wound body 2 in which a packaging medium 12 used for food packaging or the like is wound around a cylindrical core 10. The wound body 2 is stored in the storage container 3. The storage container 3 is formed of a paper material (not shown) such as cardboard or cardboard. The storage container 3 can be formed of a plurality of sheets or one sheet of paper material.

  The storage container 3 includes a container body 15. The container body 15 has a substantially rectangular parallelepiped shape. The container body 15 is formed by bending a paper material (not shown), and the paper material has elasticity (restorability) against bending to return to the original state even if it is bent once. The container body 15 accommodates the wound body 2 in which the packaging medium 12 is wound in a cylindrical shape. In the container main body 15, an upper surface in FIG. 1 is opened, and an opening 30 is formed. That is, the storage container 3 has an opening 30. The wound body 2 can be taken in and out from the opening 30. The packaging medium 12 wound around the core 10 is a transparent packaging medium made of polyvinylidene chloride as a raw material, but may be a polyvinyl chloride, polyethylene, polymethylpentene, or a multilayer packaging medium combining these. The packaging medium 12 may be roll paper, kitchen paper, aluminum foil, a cooked paper sheet, or the like.

  The storage container 3 includes a bottom plate 4, a front plate 5 erected at right angles to the bottom plate 4 on one side 31 (long side) of the bottom plate 4, and another side 32 (long side) of the bottom plate 4 facing the side 31. Are provided with a rear plate 6 erected at right angles to the bottom plate 4 and a sub-front plate 7 having a second connecting side 39 facing one side 31 of the bottom plate 4. The bottom plate 4, the front plate 5, the rear plate 6, and the auxiliary front plate 7 constitute a container body 15. The bottom plate 4 is disposed so as to face the opening 30. The sub front plate 7 is connected to the front plate 5 at the second connecting side 39. The sub-front plate 7 is folded 180 degrees inside the storage container 3 (the side storing the wound body 2) along the second connecting side 39 when forming the substantially rectangular parallelepiped container body 15. Overlaid on the front plate 5. The sub-front plate 7 that is folded is applied in a line to the surface on the front plate 5 side, and is adhered and fixed to the front plate 5. The folding is performed on the second connecting side 39. The bottom plate 4, the front plate 5, the rear plate 6, and the auxiliary front plate 7 are substantially rectangular. The bottom plate 4 has short sides 61 and 62 in addition to one side 31 and the other side 32 which are long sides. The storage container 3 includes side plates 71 and 72. The side plates 71 and 72 are erected on the short sides 61 and 62, respectively. The side plates 71 and 72 are substantially square.

  The storage container 3 further includes a lid plate 22 and a lid front plate 23. The cover plate 22 is substantially rectangular. The cover plate 22 has a first connecting side 38 facing the other one side 32 of the bottom plate 4, and is configured to be rotatably connected to the rear plate 6 at the first connecting side 38 and close the opening 30. Is done. The lid front plate 23 is erected at a right angle with respect to the lid plate 22 on one side 40 of the lid plate 22 facing the first connecting side 38, and when the lid plate 22 closes the opening 30, 5 so as to overlap the outer side of the front plate 5 (the side opposite to the sub-front plate 7 side).

  The cover plate 22 has short sides 63 and 64 in addition to the first connecting side 38 and one side 40 which are long sides. The storage container 3 includes lid side plates 73 and 74. The lid side plates 73 and 74 are erected on the short sides 63 and 64, respectively. The lid side plates 73 and 74 are substantially rectangular.

  A cutter 24 for cutting the packaging medium 12 is provided along one side 46 on the side facing the one side 31 of the bottom plate 4 of the lid front plate 23 (facing when the lid plate 22 is closed). A plurality of saw blades 80 are formed at the tip of the cutter 24. A part of the cutter 24 is configured to protrude in the direction of the bottom plate 4 when the lid plate 22 is completely closed (that is, the lid plate 22 is parallel to the bottom plate 4) and the opening 30 is closed. However, it is not limited to this.

  In the central portion of the front plate 5, a packaging medium holding portion 26 (hereinafter, appropriately holding portion 26) is formed. As a method of forming the holding part 26, a method of applying an adhesive having adhesiveness to the packaging medium 12 to provide an adhesive layer, or a varnish that has adhesiveness to the packaging medium 12 and has smoothness is used. There are a method of applying and providing a smooth layer, and a method of providing a self-adhesive packaging medium layer made of substantially the same material as the packaging medium 12 by utilizing the self-adhesiveness of the packaging medium 12 itself. A holding portion 26 that holds the packaging medium 12 is formed on the outer surface of the outer side of the front plate 5.

  The sub front plate 7 includes two holding plates 9 and a sub front plate main body. The sub-front plate main body is a portion other than the two holding plates 9 of the sub-front plate 7. The sub front plate 7 is disposed along the front plate 5 inside the front plate 5, and is bonded to the inner surface of the front plate 5. Since the holding plate 9 has a cut, it is configured to be separated from the sub front plate 7 at the cut portion and to be cut and raised from the sub front plate 7, and has an angle α (with respect to the opening 30 with respect to the front plate 5). The angle is 90 degrees-α) and the sub front plate 7 is arranged so as to protrude inside the sub front plate 7. The holding plate 9 rises from the auxiliary front plate 7 when the auxiliary front plate 7 is bent so as to overlap the front plate 5 when the container body 15 is formed. In the holding plate 9, the line in which the cut is made forms the outer peripheral line 16. The angle α is an angle of the holding plate 9 with respect to the front plate 5, and is an angle inclined when the holding plate 9 is raised so as to face the opening 30. When the packaging medium 12 pulled out from the storage container 3 and cut by the cutter 24 is pulled out from the storage container 3, the angle α does not come into contact with the holding plate 9 and is cut by the cutter 24, and then the packaging medium 12. It is good to decide so that it may contact the holding plate 9 when returning to the storage container 3.

  The holding plate 9 has an elongated shape in the longitudinal direction X. One linear side 20 on the second connecting side 39 side along the longitudinal direction X of the holding plate 9 is arranged at an angle β with respect to the second connecting side 39. The other chevron side 16 extending in the longitudinal direction X of the holding plate 9 is separated from the auxiliary front plate 7 to form the outer peripheral line 16. The side 16 (peripheral line 16) and the side 20 have a start point 17 and an end point 18, and the one closest to the middle point 19 in the longitudinal direction X of the second connecting side 39 is the starting point 17, and the second connecting side 39 The farthest from the middle point 19 is the end point 18. The start point 17 is located at a distance W1 from the second connecting side 39 along the sub-front plate 7, and the end point 18 is on the second connecting side 39. Since the holding plate 9 has the end point 18 on the second connecting side 39, the holding plate 9 can be raised at a sufficient angle α, and the starting point 17 is separated from the second connecting side 39 by a distance W1. Therefore, it is possible to suppress the rising angle α of the holding plate 9 that has risen from increasing, that is, to suppress the rising of the holding plate 9 and to maintain it stably.

  When the storage container 3 is assembled, the front plate 5 and the sub-front plate 7 are bent so as to overlap with each other along the second connecting side 39. However, since the end point 18 is on the second connecting side 39 of the holding plate 9, the restoring force that tries to return from the folded state works relatively well and rises with an angle α. It works to make it bigger (to get up more). The start point 17 is not located on the second connecting side 39 but is located at a distance W1 along the sub-front plate 7 from the second connecting side 39. The close portion is easily affected by the bending of the sub-front plate 7 and acts to reduce the angle α (that is, to prevent the rising) and to maintain the angle α. The angle α of the holding plate 9 increases from the start point 17 toward the end point 18, that is, rises more and the surface of the holding plate 9 becomes a twisted wave shape. It is preferable that the angle α1 in the portion near the starting point 17 of the holding plate 9 is 10 degrees to 30 degrees. The angle α2 in the portion near the end point 18 of the holding plate 9 is preferably 30 degrees to 90 degrees.

  Two holding plates 9 are provided, separated from the midpoint 19 of the second connecting side 39 by a length L0, respectively, on a plane 25 (indicated by a one-dot chain line in FIG. 2) passing through the midpoint 19 and perpendicular to the bottom plate 4. Since the pressing plate 9 is provided so as to be symmetrical with respect to the center point 19, the pressing plate 9 is not disposed in the portion close to the midpoint 19, and the start point 17 that is the closest point to the midpoint 19 of the pressing plate 9 is set to the second connecting side 39. By being configured so as to be separated from the storage container 3 by the distance W1, it is possible to make it difficult to contact the holding plate 9 when the packaging medium 12 is pulled out from the storage container 3.

  The description will be continued with reference to FIGS. The outer peripheral line 16 of the holding plate 9 gradually increases the distance W from the second connecting side 39 as the portion close to the start point 17 moves away from the start point 17 toward the end point 18, and the portion close to the end point 18 As the distance from the end point 18 toward the start point 17 is increased, the distance W from the second connecting side 39 is higher than the increase in the portion close to the point 17 and is rapidly increased. The distance W is preferably between 10% and 40% of the width W0 of the opening 30 so that the holding plate 9 can prevent the return of the packaging medium 12 into the storage container 3. The distance W1 is preferably within 4 mm, more preferably between 2 mm and 3 mm.

  The holding plate 9 has a length L1 in the longitudinal direction X, and the starting point 17 is separated from the middle point 19 by a length L0 in the longitudinal direction X. The length in the longitudinal direction X from the end point 18 of the pressing plate 9 to the outer surfaces of the side plates 71 and 72 is the length L2. The length L1 of the holding plate 9 covers the vicinity of the end other than the central portion in the longitudinal direction X of the storage container 3 in order to suppress the return of the packaging medium 12, and the packaging medium 12 at the end other than the central portion. It should be long enough to prevent the return of The restraining plate 9 is sufficiently cut and raised, and the restraining plate 9 does not cause excessive resistance when the packaging medium 12 is pulled out, and does not cause the cut packaging medium 12 to return into the storage container 3. Thus, the length L0 is preferably 5% to 25% of the length of the storage container 3 in the longitudinal direction X, and the length L1 is preferably 10% to 40% of the length of the storage container 3 in the longitudinal direction X. .

  Conventionally, when the holding plate is disposed only at the center portion in the longitudinal direction of the front plate, a trouble that the packaging medium returns to the storage container tends to occur at the longitudinal end portion of the front plate. In order to prevent this, there are two holding plates 9 and they are arranged as described above. The return of the end portion of the drawn packaging medium 12 close to the side plates 71 and 72 is restrained by the plate 9, and the return of the entire packaging medium 12 can be effectively prevented. For this reason, the length of L2 is desirably 30 mm or less. Suppressing the return of the central portion of the drawn packaging medium 12 is not sufficient, and in a range including the end other than the central portion of the packaging medium 12 (the range in which the holding plate 9 of FIG. 2 is disposed). It is necessary to suppress the return. When the return in the range including the end portion other than the center portion of the packaging medium 12 drawn out in this way is suppressed, the entire return of the packaging medium 12 can be prevented.

  The outer peripheral line 16 is a portion close to the starting point 17, an increasing portion 16 </ b> A in which the distance W increases as the distance from the starting point 17 increases in the longitudinal direction X, and a portion closer to the end point 18, which is closer to the end point 18. Therefore, it has the increase part 16C where the distance W increases, and the constant part 16B where the distance W is constant. The length of the increasing portion 16A in the longitudinal direction X is the length L1A, the length of the increasing portion 16C in the longitudinal direction X is the length L1C, and the length of the constant portion 16B in the longitudinal direction X is the length L1B. . The length L1A is longer than the length L1C. The increase rate of the distance W in the increase portion 16C (the overall increase rate of the distance with respect to the length) is higher than the increase rate of the distance W in the increase portion 16A (the overall increase rate of the distance with respect to the length).

  Since the restraining plate 9 is disposed so as to protrude from the auxiliary front plate 7 toward the opening 30, it has an effect of preventing the wound body 2 from jumping out of the storage container 3.

  According to the packaging medium storage container 3 according to the embodiment, the storage container 3 includes two holding plates 9, and the outer peripheral line 16 of the protruding portion of the holding plate 9 has a starting point 17 on the inner side from the second connecting side 39. Since the end point 18 is on the second connecting side 39 in the direction away from the distance W1, when pulling out the packaging medium 12 from the storage container 3, the packaging medium 12 is unlikely to contact the holding plate 9, When the packaging medium 12 is about to return to the storage container 3, the function of regulating the movement of the packaging medium 12 can be sufficiently performed. The outer peripheral line 16 of the two holding plates 9 is a portion close to the end point 18 by gradually increasing the distance W from the second connecting side 39 as the portion close to the start point 17 moves away from the start point 17 toward the end point 18. However, as the distance W from the second connecting side 39 increases away from the end point 18 toward the start point 17, the distance W from the second connection side 39 increases abruptly as compared with the increase in the portion close to the start point 17. The movement of the wrapping medium 12 can be stably regulated in a portion near the end point 18 where the movement to return to 3 is particularly likely to occur.
