Description

  The present invention relates to a wound body storage box and a storage box with a wound body, and more particularly, to a wound body storage box and a storage body with a wound body that prevent the winding body from popping out.

  Food wrap films that wrap food, dishes, or dishes such as dishes with each dish are widely used. A food plastic wrap film is typically a long plastic film (rolled body) wound in a roll, and is contained in a long rectangular parallelepiped container (container box). The required amount of film is pulled out of the roll and cut with a cutting blade attached to the lid of the container. The food wrap film has a disadvantage that the roll itself jumps out of the container when the film is pulled out of the roll. As a technique for solving such inconvenience, there is a technique in which a pressing plate (flap) extending from the top edge of the front wall of the container body to the inside of the container body is provided (for example, see Patent Document 1).

JP 2003-341666 A (FIG. 6 etc.)

  In some cases, the wound body and the storage box are manufactured in different places and then collected in a final manufacturing factory and the wound body is stored in the storage box. In this case, from the viewpoint of transport efficiency, the storage box is often carried into the final manufacturing factory in a folded state. If the storage box is stored in a folded state for a long time before being used for assembly at the final manufacturing plant, it will fold, and when used as a product, the flap will be properly There was a case where the flap could not fully perform its function without getting up (not leaving the front wall).

  In view of the above-described problems, an object of the present invention is to provide a wound body storage box and a wound body-containing storage box capable of reliably exhibiting the function of a flap.

  In order to achieve the above object, a wound body storage box according to a first aspect of the present invention includes, for example, as shown in FIG. 1, a main body portion 11 formed in a rectangular parallelepiped shape with one surface 11 h opened; A lid 16 that is pivotably connected to one side 10j and closes the opening 11h; the main body 11 includes a rear plate 14 to which the lid 16 is connected, a front plate 12 facing the rear plate 14, and a front A flap 21 extending from the front plate top side 12t in contact with the opening 11h of the plate 12 to the inside of the main body 11; and being connected to the front plate 12 by being pushed into the front plate 12 inside the main body 11. On the other hand, a pressing piece notch 12c (for example, see FIG. 2 (a)) is formed which becomes a part of the contour of the pressing piece 12p (for example, see FIG. 2 (a)) meshing with the flap 21.

  If comprised in this way, while a flap can be opened at an appropriate angle with respect to a front board, the state opened at an appropriate angle can be maintained.

  Moreover, the wound body storage box according to the second aspect of the present invention includes, for example, a main body 11 in the wound body storage box 10 according to the first aspect of the present invention as shown in FIGS. Is a sub-plate 20 that is continuous with the front plate 12 at the front plate top side 12t, and includes the sub-plate 20 provided in contact with the front plate 12 inside the main body 11 with respect to the front plate 12. The flap 21 is formed by cutting the sub-plate 20; the sub-plate 20 is formed with a sub-plate open collar cut 22c extending from the boundary with the flap 21 to the side opposite to the front plate top side 12t.

  With this configuration, when the pressing piece is pushed into the inside of the main body, the auxiliary plates on both sides of the auxiliary plate opening collar cut open, and when the pressing piece and the flap mesh with each other, the auxiliary plates on both sides of the auxiliary plate opening collar cutting are provided. The plate acts in a direction in which the pressing piece is pressed against the flap, and the flap can be maintained at an appropriate angle and with an appropriate strength, and the strength of the front plate can be improved. Further, when the housed winding body is pulled out, the sub-plate opened by the sub-plate open collar notch comes into contact with the winding body with a line, and contributes to preventing the winding body from popping out while stabilizing the drawer. It will be.

  In addition, the container with a wound body according to the third aspect of the present invention includes, for example, a wound body 31r around which a thin film-like object 31f is wound, as shown in FIG. 2B; The wound body storage box 10 according to the first aspect or the second aspect.

  If comprised in this way, it will become an accommodation box containing a wound body which can make the function of a flap appear reliably.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to open a flap at an appropriate angle with respect to a front board, the state opened at an appropriate angle can be maintained, and the function of a flap can be exhibited reliably.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar members are denoted by the same or similar reference numerals, and redundant description is omitted.

  First, referring to FIG. 1 and FIG. 2, a wrap carton 10 as a wound body storage box and a winding in which a wrap roll 31r as a wound body is housed in the wrap carton 10 according to the embodiment of the present invention. The wrapped carton 1 as a body containing box will be described. FIG. 1 is a rear perspective view of the wrap carton 10. FIG. 2 is a view for explaining the wrap carton 10 and the wrap carton 1, (a) is a front view of the opened wrap carton 10, (b) is a side sectional view of the wrap carton 1, and (c) is a side view. FIG. 3 is a partial elevational view around an open collar portion 22 inside a wrap carton 10. The wrap roll 31r is obtained by winding a wrap film 31f as a long thin film into a roll shape. In the present embodiment, polyvinylidene chloride having a thickness of 5 to 20 μm is used for the wrap film 31f. The wrap carton 10 includes a main body 11 that accommodates the wrap roll 31 r and a lid 16 that is connected to the main body 11.

  The main body 11 is a box in which one of the elongated surfaces is an opening 11h with respect to a rectangular parallelepiped having a size capable of accommodating an unused wrap roll 31r. The size of the main body 11 is formed as small as possible while a gap that does not prevent the accommodated unused lap roll 31r from rotating around the axis is formed. The main body 11 includes a front plate 12, a bottom plate 13, and a rear plate 14 that form side surfaces of the rectangular parallelepiped in cooperation with the opening 11h, and two side plates 15 that form end surfaces of the rectangular parallelepiped. The bottom plate 13 faces the opening 11 h, and the front plate 12 and the rear plate 14 are orthogonal to the opening 11 h and the bottom plate 13. The main body 11 has a sub-plate 20 that is continuous with the front plate 12 at a front plate top side 12t that is one side of the front plate 12 that forms the opening 11h. The sub plate 20 is substantially the same size as the front plate 12 and is provided inside the main body 11 with respect to the front plate 12.

  The lid portion 16 is a member that closes the opening 11 h of the main body portion 11, and includes a lid plate 17, a lid lid piece 18, and a side lid piece 19. The lid plate 17 is a rectangular flat plate member having substantially the same size as the surface of the opening 11h, and can be formed into a rectangular parallelepiped with the main body 11 closed by fitting the lid plate 17 to the opening 11h. That the cover plate 17 is substantially the same size as the surface of the opening 11h means that the cover plate 17 includes a case where the thickness of the lid cover piece 18 and the thickness of the side cover piece 19 are larger. The cover plate 17 has one side in the longitudinal direction that is the one side that forms the opening 11 h of the main body 11, and is connected by a hinge side 10 j that is one side of the rear plate 14. In other words, the main body 11 and the cover plate 17 are connected via the hinge side 10j. The cover plate 17 is configured to be rotatable with respect to the main body 11 with the hinge side 10j as a rotation axis. The cover plate 17 can move between a position where the bent side 17f facing the hinge side 10j is in contact with the front plate 12 and a position outside the rear plate 14 when seen in a plan view. Yes.

  The lid piece 18 is provided extending to the main body 11 side so as to be orthogonal to the lid plate 17 via the bent side 17f. The lid piece 18 has a width at both ends in the longitudinal direction (the length in the short side direction of the rectangular front plate 12) is about ½ of the length in the short side direction of the front plate 12, and the width of the central portion in the longitudinal direction. The front plate 12 is about 3/4 of the length in the short side direction, and the tip side 18p facing the bent side 17f is formed in a V shape. A cutting blade 18 c for cutting the wrap film 31 f is attached to the tip side 18 p of the lid piece 18. A total of two side lid pieces 19 are provided at both ends of the lid plate 17 and the lid lid piece 18, and are attached orthogonally to both the lid plate 17 and the lid lid piece 18. The side lid piece 19 is formed in a rectangle whose long side is the same length as the short side of the lid plate 17 and whose short side is substantially the same length as the end of the lid lid piece 18. The lid portion 16 configured in this manner covers the opening 11h of the main body 11 when the opening 11h is closed.

  In the present embodiment, the main body 11 and the lid 16 are formed by processing coated cardboard having a thickness of about 0.45 to 0.7 mm. In the present embodiment, for convenience of explanation, the main body part 11 and the lid part 16 are distinguished from the viewpoint of the function. However, the main body part 11 and the lid part 16 are formed by integrally cutting and assembling one base paper. Has been. The surface of the main body portion 11 and the lid portion 16 is printed with a design that provokes consumers' willingness to purchase, and then subjected to surface treatment (for example, application of an ultraviolet curable varnish).

  A holding portion for holding the wrap film 31 f is formed on the outer surface of the front plate 12 (not shown). As a method of forming the wrap film holding portion, there are a method of providing a pressure-sensitive adhesive layer, a method of providing a smooth layer, a method of providing a self-adhesion layer utilizing the self-adhesion of the wrap film 31f itself, and the like.

  In the wrap carton 10 generally configured as described above, the sub-plate 20 is cut and a flap 21 is formed. The flap 21 suppresses the wrap roll 31r from popping out of the main body 11 when the wrap film 31f is pulled out from the wrap roll 31r, and is not held by the wrap film holding portion after the used wrap film 31f is cut, This is a portion formed to prevent the tip of the wrap film 31f near the top side 12t of the front plate from rewinding and adhering to the wrap roll 31r. The flap 21 has a depth 21d of a predetermined length from the front plate top side 12t to the sub plate 20 side, and the length in the direction in which the front plate top side 12t extends is cut into the sub plate 20 over the width 21w. Has been. The flap 21 is integrally connected to the front plate 12 at the front plate top side 12t, and can move around the axis so as to approach and separate from the front plate 12 with the front plate top side 12t as an axis. It has become.

  The depth 21d of the flap 21 is typically such a length that the flap 21 does not interfere with an unused lap roll 31r accommodated in the wrap carton 10. In other words, an imaginary line connecting the front plate top side 12t and the center of the wrap roll 31r when the unused wrap roll 31r is in contact with the bottom plate 13 and the sub-plate 20 and viewed from the side cross-section of the wrapping carton 1. It is preferable that the depth 21d be formed to a length shorter than the distance between the front plate top side 12t and the surface of the lap roll 31r on Lv. In the present embodiment, two flaps 21 are formed having a width 21 w that is less than ½ of the length of the main body 11 in the longitudinal direction. By dividing the flap 21, it is possible to suppress a decrease in torsional resistance per one flap 21 and to suppress a decrease in strength. In addition, by dividing the flap 21 into two parts without being divided too much, it is possible to suppress an increase in labor for raising the flap 21 while suppressing a decrease in strength. Further, the flap 21 is formed with a fitting groove 21g in the longitudinal center portion of the side facing the front plate top side 12t.

  The front plate 12 is formed with a pressing piece notch 12c at a position whose longitudinal direction corresponds to the fitting groove 21g. The pressing piece notch 12c is a cut that separates the pressing piece 12p from the front plate 12, and forms a part of the outline of the pressing piece 12p. The pressing piece 12p is a part that raises the flap 21 (moves in a direction away from the front plate 12) and maintains the raised flap 21 in a predetermined state. The predetermined state is a state in which the flap angle θ, which is an angle formed by the front plate 12 and the flap 21, is a predetermined angle when viewed from a side cross-section of the wrap carton 10 (FIG. 2B). The predetermined angle is an angle at which the flap 21 exhibits its function, and is preferably 30 to 40 °, and may be an angle at which the flap 21 is positioned on the opening 11h side with respect to the virtual line Lv.

  The pressing piece 12p is typically formed to be about the size of a thumb of a general adult hand, but can be appropriately changed according to the size, material, etc. of the wrap carton 10. The larger pressing piece 12p is preferable from the viewpoint of stabilizing the holding of the flap 21, and the smaller one is preferable from the viewpoint of suppressing a decrease in the strength of the front plate 12. A pressing piece 12p formed by removing a part of the front plate 12 is connected to the front plate 12 at a connection side 12j which is a side on the bottom plate 13 side. The pressing piece 12p is formed so that it can be bent at the connection side 12j and fall down to the inside of the main body 11 from a position on the same plane as the front plate 12. Of the outline of the pressing piece 12p, a portion other than the connection side 12j becomes the pressing piece notch 12c. The notch 12c for the pressing piece may be formed in a perforation in which the front plate 12 and the pressing piece 12p are intermittently connected before the pressing piece 12p is pushed into the inside of the main body 11, and the pressing piece 12p May be formed in a complete cut only in a state of being fitted to the front plate 12.

  On the pressing piece 12p, a fitting protrusion 12f that fits into the fitting groove 21g of the flap 21 is formed on the side of the opening 11h (that is, the side facing the connecting side 12j). The fitting protrusion 12f is typically formed to have a width slightly larger than the width of the fitting groove 21g from the viewpoint of preventing the pressing piece 12p fitted to the flap 21 from being detached from the flap 21. The fitting between the fitting groove 21g of the flap 21 and the fitting protrusion 12f of the pressing piece 12p is a form of meshing between the flap 21 and the pressing piece 12p. The pressing piece 12p is formed at an appropriate position of the front plate 12 so that the flap angle θ becomes a predetermined angle when the pressing piece 12p is pushed inside the main body 11 and meshes with the flap 21. In the present embodiment, as shown in FIG. 2A, the pressing piece 12p is formed to be closer to the front plate top side 12t than the front end side 18p when the lid 16 is closed.

  As shown in FIG. 3 (a), if the pressing piece 12p is a pressing piece 12pA having an apple pattern, the pressing piece 12p provided from the functional aspect is less likely to be detrimental in terms of design, but rather induces consumers to purchase. This is preferable because it can also lead to In addition, it is preferable that the pressing piece 12pA has an apple pattern because the presence of the fitting protrusion 12f on the edge of the apple does not give a sense of incongruity. Further, as shown in FIG. 3B, the pressing piece 12p may be a pressing piece 12pB having a ridge pattern. Also in this case, the fitting protrusion 12f can be regarded as a heel. Or as shown in FIG.3 (c), it is good also considering the pushing piece 12p as the pushing piece 12pC of a fish pattern. In this case, the fitting protrusion 12f can be regarded as a dorsal fin. In addition to the examples shown here, the pressing piece 12p may be a pattern of fruits such as melons other than apples and strawberries, a pattern of foods other than fruits, and a pattern of dishes other than foods. Thus, by giving a pattern to the pressing piece 12p, it is possible to have variations in design while maintaining the function.

  1 and 2 again, the explanation of the wrap carton 10 will be continued. As shown in FIG. 2 (c), the sub-plate 20 faces the bottom plate 13 in a direction perpendicular to the front plate top side 12t from the boundary 20b with the flap 21 at a position facing the fitting groove 21g. An extended sub-plate open collar cut 22c is formed. The sub-plate opening collar notch 22c typically extends to the bottom plate 13 side from a position corresponding to the connection side 12j formed on the front plate 12, and the height of the front plate 12 (the vertical distance from the bottom plate 13 to the opening 11h). ) Of about 1/2 to 2/3.

  Further, the sub-plate 20 is formed with a fold line 22f that connects an end portion of the sub-plate open collar cut 22c on the bottom plate 13 side and a boundary 20b away from the sub-plate open collar cut 22c. The fold line 22f is linear and is formed on both sides of the sub-plate open collar cut 22c. Accordingly, two fold lines 22f are formed. The angle between the sub-plate open collar cut 22c and the fold line 22f is preferably approximately 30 to 60 °, and is 45 ° in the present embodiment. The sub-plate 20 has a triangular open collar portion 22 surrounded by a boundary 20b, a sub-plate open collar cut 22c, and a fold 22f on both sides of the sub-plate open collar cut 22c. The fold line 22f of the present embodiment is for determining a place and a range to be bent when the open collar portion 22 is pushed inside the main body 11, and when the external force applied to the open collar portion 22 is removed. Further, the open collar portion 22 is formed so as to return to the vicinity of the front plate 12 or until it comes into contact with the front plate 12. By forming the open collar portion 22, the front plate 12 on which the pressing piece 12p is formed can be reinforced.

  Next, with reference to FIG.1 and FIG.2, the effect | action of the carton 1 with a wrap is demonstrated. The operation of the wrap carton 10 will be described as part of the operation of the wrapping carton 1. The unopened carton 1 with a wrap has a cut piece (not shown) connected to the tip of the lid piece 18 through a perforation (not shown) on the tip side 18p. The plate 12 is bonded at a plurality of points. When the wrap film 31f is used for the first time, the cut piece (not shown) is separated from the lid piece 18 by being cut at the perforation (not shown) while being peeled off from the front plate 12. By opening the wrap carton 10 in this manner, the lid 16 can be rotated with respect to the main body 11.

  When the wrap carton 10 is opened and the lid portion 16 is opened, a pressing piece 12p appears on the front plate 12 which is the front. The pressing piece 12p at this time is still flush with the front plate 12. On the other hand, when looking into the main body 11, the flap 21 extends from the front plate top side 12 t into the main body 11. In this case, the flap 21 may have an insufficient flap angle θ (for example, 10 ° or less) for the flap 21 to function effectively. This is typically because the wrap carton 10 was creased when it was manufactured in a different factory from the factory where the wrapped carton 1 is manufactured and stored in a folded state. is there.

  Therefore, in the carton 1 with a wrap of the present embodiment, the flap 21 is effectively functioned as follows. First, the pressing piece 12p formed on the front plate 12 is pushed into the main body 11 with a finger. Then, the pressing piece 12p is separated from the front plate 12 along the pressing piece notch 12c, bent from the connection side 12j, and falls to the inside of the main body 11. In the process in which the pressing piece 12p falls, the flap 21 and the open collar portion 22 are pushed by the pressing piece 12p and spread. When the pressing piece 12p falls down and the fitting protrusion 12f of the pressing piece 12p reaches the fitting groove 21g of the flap 21, the fitting protrusion 12f fits into the fitting groove 21g. Thereby, the flap 21 maintains the flap angle θ at a predetermined angle, and the function of the flap 21 can be sufficiently exhibited. When the fitting protrusion 12f does not fit properly into the fitting groove 21g, the flap 21 may be pushed toward the pressing piece 12p at a position where the fitting protrusion 12f is aligned with the fitting groove 21g.

  In a state where the flap 21 and the pressing piece 12p are fitted, an elastic force is exerted so that the open collar portion 22 returns to the front plate 12 side. Due to this elastic force, a force acts in a direction in which the pressing piece 12p is pressed against the flap 21, and the fitting projection 12f and the fitting groove 21g are not easily disconnected. Further, the open collar portion 22 supports the pressing piece 12p fitted to the flap 21, and the pressing piece 12p supported by the opening collar portion 22, the flap 21, and the front plate 12 form a triangular cross section. As a result, the strength of the front plate 12 can be improved.

  The wrapping carton 1 opened as described above has a wrap roll 31r in the main body 11. The wrap roll 31r has a drawer seal (not shown) attached to the tip of the wrap film 31f, and the tip of the wrap film 31f is peeled off from the wrap roll 31r by pulling out the drawer seal (not shown). The wrap film 31f can be pulled out easily. When using the wrap film 31f, the wrap film 31f is pulled out from the wrap roll 31r by a necessary length and cut by the cutting blade 18c. However, since the flap 21 is maintained at an appropriate flap angle θ, When pulling out the film 31f, the wrap roll 31r is effectively suppressed from jumping out of the main body 11. Further, since the flap 21 is maintained at an appropriate flap angle θ, even if the wrap roll 31r moves slightly in the direction of rewinding after the wrap film 31f is cut, the leading end of the wrap film 31f is on the flap 21. Since it will be in the riding state, it can suppress that the front-end | tip of the wrap film 31f sticks to the wrap roll 31r. Further, since the pressing piece 12p supported by the open collar portion 22, the flap 21 and the front plate 12 cooperate to form a three-dimensional shape on the back of the front plate 12, the front plate is cut when the wrap film 31f is cut. It is possible to reduce the distortion that occurs when the body 12 is pushed inside the main body 11.

  As described above, in the carton 1 with a wrap according to the present embodiment, the flap 21 can be opened at an appropriate flap angle θ with respect to the front plate 12 and is opened at an appropriate flap angle θ. Therefore, the function of the flap 21 can be surely exhibited. Further, the flap 21 is formed by cutting the sub-plate 20, and the open collar portion 22 is formed on the sub-plate, so that a decrease in strength of the front plate 12 opened by pressing the pressing piece 12p is suppressed. be able to.

  In the above description, the thin film-like long object is the wrap film 31f, but it may be an aluminum foil or a cooking sheet (paper product coated with silicon or the like that allows water vapor to pass through but does not allow liquid water to pass through). There may be.

  In the above description, the flap 21 is formed by cutting the sub plate 20. However, the main body 11 does not include the sub plate 20, and only the flap 21 is connected to the front plate top side 12 t. It may be a configuration. If comprised in this way, the use material of the lap carton 10 can be reduced. On the other hand, it is preferable that the main body 11 includes the sub plate 20 because the strength of the main body 11 is improved.

  In the above description, the fitting groove 21g is formed in the flap 21 and the fitting protrusion 12f is formed in the pressing piece 12p. However, the fitting groove is formed in the pressing piece 12p and the fitting protrusion is the flap 21. It may be formed. Further, instead of forming the fitting groove and the fitting projection, a notch for engagement is made in the flap 21, and the pressing piece 12p is sandwiched between the notching, so that the flap 21 and the pressing piece 12p May be configured to mesh with each other. The notch for meshing may be formed not in the flap 21 but in the pressing piece 12p, and may be formed in both the flap 21 and the pressing piece 12p.
