[Technical Field]

[0001] The present disclosure relates to a wrap device that is a wrap holder or wrap case. [Background technology]

[0002] Japanese Patent No. 7405461 discloses a wrap holder that can prevent wrap from unwinding. The wrap holder is attached to a wrap carton that contains a wrap roll around which wrap is wound. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7405461 Summary of the Invention [Problem to be solved by the invention]

[0004] The inventor further improved the wrap holder from the viewpoints of ease of gripping the wrap and design. Furthermore, the inventor developed a wrap case to replace the conventional wrap carton from the viewpoints of stability when the wrap is not in use and design. [Means for solving the problem]

[0005] The wrapping device according to a first embodiment of the present disclosure is a holder-shaped wrapping device that is attached to a wrapping carton containing a wrap roll wrapped with wrapping. The wrapping device includes a holder bottom that accommodates the bottom of the wrapping carton, a sidewall extending from the holder bottom and constituting the sidewall on which the wrapping is pulled out, and a plate-shaped attachment portion provided on the surface of the sidewall that utilizes the electrostatic charge of the wrapping pulled out of the wrapping carton to attach the electrostatically charged wrapping. If the extension direction of the sidewall is defined as upward and the side perpendicular to the sidewall on which the attachment portion is provided is defined as forward, the attachment portion has a recess that is recessed upward. The sidewall is provided with a gripping aid having a base end located within the recess and two spaced-apart protrusions extending downward and forward from the base end. At least a portion of each of the protrusions is located forward of the surface of the attachment portion. Similarly, a case-shaped wrapping device also includes the sidewall, the recess, and the gripping aid.

[0006] A wrapping device according to a second aspect of the present disclosure is a case-shaped wrapping device for storing a wrap roll wound with wrap, comprising: a box-shaped case body having an opening; a lid provided on the case body to open and close the opening of the case body; and a blade provided on the lid or the case body for cutting the wrap. A plate-shaped attachment portion is provided on the surface of a side wall portion, which is the side from which the wrap is pulled out, to attach the electrostatically charged wrap by utilizing the charged state of the wrap pulled out from the case body. If the direction from the bottom surface of the case body toward the opening is defined as "upward" and the side perpendicular to the side wall portion on which the attachment portion is provided is defined as "forward," when the lid is closed, an engagement claw is formed on a pressing side surface that constitutes the front side of the lid, protruding rearward and engaging with the attachment portion. [Effects of the Invention]

[0007] According to the wrapping device of the first embodiment of the present disclosure, the grip assisting portion lifts a portion of the wrap attached to the attachment portion forward (toward the user during use) at the recessed portion. This allows the user to easily grip the wrap that straddles the two protruding portions of the grip assisting portion. In other words, the user experience is greatly improved. By positioning the base end of the grip assisting portion within the recessed portion, the attachment function and grip assisting function can coexist in a single, unified area. This not only improves the user experience, but also provides design advantages.

[0008] In the wrapping device according to the second embodiment of the present disclosure, when the lid is closed, the engaging claws catch on the attachment portion, which prevents the lid from floating up (opening) naturally, improving the stability of the wrap case when the wrap is not in use and preventing the design from being impaired by the lid floating up.

[0010] Hereinafter, as a mode for carrying out the present invention, a wrap device (wrap holder 1, wrap case) that is one embodiment of the present invention will be described in detail with reference to the drawings. In addition to the following examples, the present invention can be carried out in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Since this embodiment is an improved version of Japanese Patent No. 7405461, the names and descriptions in Japanese Patent No. 7405461 are referenced and quoted in some descriptions of this embodiment.

[0011] As shown in FIGS. 1 to 5, a wrap holder 1, which is an example of a wrap device of this embodiment, is a member that is detachably attached to a wrap carton 9. As shown in FIGS.

[0012] (wrapped carton) As shown in Fig. 6, the wrap carton 9 is a case that houses a wrap roll 90 around which wrap is wound. The wrap carton 9 is a general case in which wrap is stored. The wrap carton 9 includes a box-shaped carton body 91 that houses the wrap roll 90, and a lid 92 for opening and closing an opening 91a of the carton body 91. The wrap roll 90 is formed in a cylindrical shape.

[0013] In the following description, unless otherwise specified, the lap holder 1 will be described as being configured in a state where the lap holder 1 is attached to the lap carton 9 and the lid portion 92 of the lap carton 9 is closed.

[0014] The carton body 91 is a box-shaped part with an open top. An upper opening 91a is formed by the bottom, front side, rear side, left side, and right side of the carton body 91. Note that, in this description, up, down, left, right, front, and rear are based, as an example, on the assumption that the opening 91a is located at the top of the carton body 91. Note that, regarding the descriptions of directions, "up" can also be referred to as the "opening direction" from the bottom toward the opening, "down" can also be referred to as the "bottom direction" from the opening toward the bottom, "left" can also be referred to as "one longitudinal direction or one roll axial direction," "right" can also be referred to as "the other longitudinal direction or the other roll axial direction," "front" can also be referred to as "the wrap pulling direction (or the front side when the wrap is in use)," and "rear" can also be referred to as "the wrap unwinding direction (or the back side when the wrap is in use)."

[0015] The lid 92 is integrally formed with the carton body 91. The lid 92 has a top surface (upper surface), a pressing side surface (front side surface) 921, a left side surface, and a right side surface. The top surface extends forward from the upper rear end portion (upper part of the rear side surface) of the carton body 91 so as to close the opening 91a.

[0016] The pressing side surface 921 extends downward from the front end of the top surface so as to face the front side surface of the carton body 91. In this embodiment, the blade 93 for cutting the wrap is provided at the tip (lower end) of the pressing side surface 921. The blade 93 extends in the left-right direction. The left side surface of the lid portion 92 faces the left side surface of the carton body 91. The right side surface of the lid portion 92 faces the right side surface of the carton body 91. The lower ends of each side surface of the lid portion 92 are positioned higher than the lower end of the carton body 91. The lid portion 92 is positioned outside the carton body 91 so as to cover the top of the carton body 91.

[0017] The user can open the opening 91a by rotating the lid 92 upward around the connection between the top surface of the lid 92 and the rear side of the carton body 91. After pulling out the wrap from the opening 91a, the user closes the lid 92 and presses the pressing side 921 while twisting the wrap carton 9 and cutting the wrap with the blade 93. The wrap carton 9 is formed integrally from paper or the like, and a linear crease is formed at the connection between the lid 92 and the carton body 91.

[0018] (lap holder) As shown in Figs. 1 to 5, the wrap holder 1 comprises a holder body 2, an attachment portion 3, and a gripping assist portion 4. The holder body 2 is a member that is attached to the carton body 91 so as to cover at least a portion of the carton body 91. The holder body 2 is made of, for example, resin or metal. The holder body 2 of this embodiment is a one-piece product made of resin.

[0019] The holder main body 2 includes a holder bottom 21, side wall portions 22, and an attachment auxiliary portion 23. The holder bottom 21 is formed in a box shape (shallow box shape) that opens upward so that the bottom of the carton main body 91 can be accommodated therein (so that it can be attached to the bottom). It can be said that the carton main body 91 fits into the holder bottom 21. The holder bottom 21 may be in the shape of a frame (e.g., a skeletal shape) as long as the bottom (lower end) of the carton main body 91 can be accommodated therein.

[0020] The side wall 22 extends (rises) from the holder bottom 21 and forms the side wall on the side from which the wrap is pulled out. In other words, the side wall 22 extends upward from the front end surface (front side surface) of the holder bottom 21 so as to face the front side surface of the carton body 91. The side wall 22 is disposed between the pressing side surface 921 and the front side surface of the carton body 91. The side wall 22 is a plate-shaped portion disposed so as to fit along and cover the front side surface of the carton body 91. The upper end of the side wall 22 is located at a position corresponding to (slightly above) the upper end of the carton body 91.

[0021] The attachment auxiliary portion 23 extends rearward from the upper end of the side wall portion 22. The attachment auxiliary portion 23 restricts upward movement of the wrap roll 90 and the front side surface of the carton body 91. The holder bottom portion 21 and the attachment auxiliary portion 23 make the attachment of the holder body 2 to the carton body 91 more stable. The holder bottom portion 21 and the attachment auxiliary portion 23 each function as attachment pieces for attaching the holder body 2 to the carton body 91.

[0022] The attachment aid 23 is positioned so that at least a portion of the attachment aid 23 comes into contact with the wrap when the wrap is pulled out. The wrap passes between the attachment aid 23 and the lid 92 while contacting the attachment aid 23, and is pulled out to the outside.

[0023] The loading aid 23 in this embodiment is made of resin and functions as a charge-promoting portion that promotes charging of the wrap. When the wrap is pulled out of the wrap carton 9, it comes into contact with at least a portion of the loading aid 23. The wrap is pulled out while in contact with the resin loading aid 23. In other words, at least a portion of the loading aid 23 functions as a charge-promoting portion. It can also be said that the holder main body 2 is equipped with a charge-promoting portion (23). The loading aid 23 does not necessarily have a charge-promoting function. As another example of a shape, the loading aid 23 may be formed so as to be folded back from the side wall 22, i.e., so as to extend rearward and downward from the upper end of the side wall 22. The loading aid 23 in this embodiment is formed by being bent from the side wall 22. The angle (downward and rearward angle) between the loading aid 23 and the side wall 22 is preferably, for example, between 60 degrees and 90 degrees. This more effectively suppresses the lifting (protrusion) of the wrap roll 90 that occurs when the wrap is pulled out. The attachment assisting portion 23 has the functions of assisting attachment, promoting charging, and preventing the roll from jumping out.

[0024] The attachment portion 3 is a plate-shaped member provided on the side wall portion 22. The attachment portion 3 is made of, for example, a material different from that of the side wall portion 22, and is adhered to the surface of the side wall portion 22. The attachment portion 3 is disposed in a position facing the pressing side surface 921. The attachment portion 3 attaches the wrap pulled out of the wrap carton 9 to itself by utilizing static electricity. The attachment portion 3 is a member configured to allow electrically charged wrap to adhere to it. The attachment portion 3 is a portion for attaching the electrostatically charged wrap by utilizing the charged state of the wrap pulled out of the wrap carton 9.

[0025] The wrap pulled out from the wrap roll 90 becomes charged due to the peeling electrification phenomenon. Therefore, the charged wrap adheres to the attachment portion 3 due to static electricity. For example, after the charging of the charged wrap pulled out from the wrap roll 90 is promoted by the attachment assisting portion 23, the wrap is cut by the blade 93 while being pressed by the user toward the attachment portion 3 via the pressing side surface 921. As a result, after the wrap is cut, the wrap adheres to the attachment portion 3, and the wrap is prevented from being wound back into the carton body 91.

[0026] The attachment portion 3 in this embodiment is a plate-shaped member made of a resin material such as acrylic or polycarbonate. The attachment portion 3 may be made of a resin material to which plastic wrap adheres more easily than the material of the holder body 2. The attachment portion 3 in this embodiment is configured to be stronger than the side wall portion 22 (holder body 2). The material of the attachment portion 3 is harder than the material of the side wall portion 22. In other words, the attachment portion 3 in this embodiment is made of a material that is harder than the side wall portion 22 and to which plastic wrap adheres more easily. As an example, the holder body 2 may be made of polypropylene, and the attachment portion 3 may be made of acrylic. The thickness of the attachment portion 3 is about 2 mm. The attachment portion 3 also functions as a reinforcing material that suppresses deformation of the holder body 2. The side wall portion 22 (holder body 2) may be made of a flexible resin, such as polyethylene or polyvinyl chloride in addition to polypropylene. The attachment portion 3 may be made of polycarbonate or rigid polyvinyl chloride.

[0027] The attachment portion 3 is provided with a recess 3a that is recessed upward (opens downward). In this embodiment, the recess 3a is formed, for example, at a position corresponding to the longitudinal center (left-right center) of the side wall portion 22. The recess (indentation) of the recess 3a forms an area where the wrap does not adhere (hereinafter also referred to as a "non-attachment area") within the area where the attachment portion 3 is arranged. The user can use this non-attachment area of ​​the recess 3a to easily pick up the wrap.

[0028] A gripping auxiliary portion 4 is provided on the side wall portion 22. The gripping auxiliary portion 4 is arranged so that at least a portion of it fits within the recess 3a. The gripping auxiliary portion 4 is an inclined portion that moves away from the side wall portion 22 (i.e., toward the front) from the base end portion 41 toward the tip. The gripping auxiliary portion 4 is formed in a flat plate shape overall.

[0029] The knob assisting portion 4 has a base end portion 41 located within the recess 3a, and two spaced apart protrusions 42, 43 extending downward and forward from the base end portion 41. The knob assisting portion 4 is formed as a whole in a concave shape that is recessed upward (opens downward). The concave shape of the knob assisting portion 4 is formed so that the user can pinch the wrap located between the protrusions 42, 43 with their fingers. The protrusion 42 forms the left end portion of the knob assisting portion 4, and the protrusion 43 forms the right end portion of the knob assisting portion 4.

[0030] The tip of gripping assisting portion 4 (the tip of each protrusion 42, 43) is located forward of the surface (front end surface) of attachment portion 3. Note that it is not limited to the tip, as long as at least a portion of protrusions 42, 43 is located forward of the surface of attachment portion 3. The bottom surface of recess 3a is located above gripping assisting portion 4. In other words, a portion of attachment portion 3 (the portion where the wrap is attached) and gripping assisting portion 4 (the portion where the wrap is lifted forward) are arranged side by side in the vertical direction.

[0031] The tip of gripping auxiliary part 4 is located below the opening of recess 3a. Base end 41 of gripping auxiliary part 4 is disposed adjacent to the bottom surface of recess 3a. In this way, gripping auxiliary part 4 is a part where base end 41 is located within recess 3a and the tip is located below the bottom end of recess 3a and forward of the surface of attachment part 3. Grip auxiliary part 4 is covered by pressing side surface 921 when lid part 92 is closed.

[0032] The grip assisting portion 4 has two protrusions 42, 43 that form an area (hereinafter also referred to as the "grip area") that lifts the wrap toward the user. The distance d between the two protrusions 42, 43, which are positioned forward of the surface of the attachment portion 3, is, for example, large enough to accommodate at least the thumb and index finger of an adult user (e.g., 10 mm or more). Note that even if this distance d (opening width of the grip assisting portion 4) is less than 10 mm, the gap between the protrusions 42, 43 makes it possible to grip the wrap between the pads of the fingers. However, from the perspective of ease of gripping, it is preferable that the distance d be 10 mm or more, and even more preferably 15 mm or more, taking into account the width of an adult's fingers and ease of gripping.

[0033] The gripping assisting part 4 separates a portion of the wrap attached to the attachment part 3 at the position of the recess 3a and lifts it forward (toward the user during use). This allows the user to easily grip the wrap that spans between the protruding parts 42 and 43 of the gripping assisting part 4 (the gripping area). In other words, the user experience is greatly improved. By positioning the base end 41 of the gripping assisting part 4 within the recess 3a, the attachment area and the gripping area can be arranged vertically and coexist in a single, unified area. This not only improves the user experience, but also allows the lid part 52 to cover the attachment part 3 and the gripping assisting part 4 when the wrap is not in use, which is advantageous in terms of design.

[0034] The knob auxiliary part 4 of this embodiment is formed by a part of the side wall part 22. That is, the knob auxiliary part 4 is formed by bending a part of the side wall part 22 forward. A part of the side wall part 22 is cut along the shape of the knob auxiliary part 4 except for the base end part 41. Therefore, a through hole of the same shape as the knob auxiliary part 4 is formed in the side wall part 22. This makes it possible to form the knob auxiliary part 4 without increasing the number of parts. Furthermore, because it is made of resin and is formed in a bent shape, the connection part between the knob auxiliary part 4 and the side wall part 22 is easily elastically deformed, so the knob auxiliary part 4 flexibly moves back and forth in response to the opening and closing of the lid part 92, improving operability and design freedom.

[0035] From the viewpoint of ease of gripping, it is preferable that the lower end of grip assisting portion 4 is located below the lower end of recess 3a. Also, from the viewpoint of design, it is preferable that the tip of grip assisting portion 4 is located above the lower end of pressing side surface 921 (i.e., located inside lid portion 92) when lid portion 92 is closed.

[0036] The recess 3a and the grip assisting portion 4 are preferably disposed in the left-right center (longitudinal center) of the holder body 2, but may be disposed, for example, at the left or right end. Furthermore, the separation distance d between the protrusions 42 and 43 may be formed to be larger than the width of three fingers (for example, 30 mm or more) so that the wrap can be grasped using, for example, the index finger, middle finger, ring finger, and palm. In this case, the recess 3a is also enlarged accordingly.

[0037] By forming the base end 41 of the gripping assisting portion 4 at a position adjacent to the bottom surface of the recess 3a, the gripping assisting portion 4 fits better into the recess 3a. This also allows the gripping assisting portion 4 to have a gentle forward slope in a configuration in which the tips of the protrusions 42, 43 extend forward from the surface of the attachment portion 3. This reduces interference with the wrap by the gripping assisting portion 4, allowing the wrap to separate more naturally from the attachment portion 3. It also allows the spatial area formed between the protrusions 42, 43 when viewed from the front to be widened, improving the ease of gripping.

[0038] (Summary of lap holder configuration) The wrap holder 1 of this embodiment is a holder-shaped wrap device that is attached to a wrap carton 9 that houses a wrap roll 90 around which wrap is wound. The wrap holder 1 includes a holder bottom 21 that fits the bottom of the wrap carton 9, a side wall 22 that extends from the holder bottom 21 and forms the side wall from which the wrap is pulled out, and a plate-shaped attachment portion 3 that is provided on the surface of the side wall 22 and that utilizes the charged state of the wrap pulled out of the wrap carton 9 to attach the electrostatically charged wrap. In summary, the extension direction of the side wall 22 (which can also be referred to as the extension direction of the side wall 22 from the holder bottom 21 or the rising direction of the side wall 22 from the holder bottom 21) is defined as the upside, and the side of the side wall 22 perpendicular to the side wall 22 where the attachment portion 3 is provided is defined as the front (the side of the side wall 22 perpendicular to the side wall 22 where the wrap roll 90 is located can also be defined as the rear). The attachment portion 3 has a recess 3a that is recessed upward. The side wall 22 is provided with a gripping auxiliary portion 4 that extends downward and forward from a base end 41 located within the recess 3a. The gripping auxiliary portion 4 has two spaced apart protrusions 42, 43 that extend downward and forward. The tip of each of the protrusions 42, 43 is located forward of the surface of the attachment portion 3.

[0039] The knob assisting portion 4 is formed in a concave shape that is recessed upward. The distance d between the tips of the two protrusions 42, 43 is 10 mm or more. The tips of each of the protrusions 42, 43 are located below the lower end of the recess 3a. The base end portion 41 is disposed adjacent to the bottom surface of the recess 3a. The knob assisting portion 4 is formed by bending a portion of the side wall portion 22 forward. The extension directions of the two protrusions 42, 43 are substantially parallel to each other. The two protrusions 42, 43 may be shaped, for example, V-shaped, with the distance between them increasing toward the tips (separating in the left-right direction).

[0040] (wrap case) As shown in Figures 7 to 10, the wrap case 5 of this embodiment is a case-shaped wrapping device that houses a wrap roll 90 around which wrap is wound. The overall shape (box shape) of the wrap case 5 is similar to that of the wrap carton 9. The wrap case 5 is formed in a box shape so that the wrap roll 90 can be housed therein (see Figure 6).

[0041] The wrap case 5 includes a box-shaped case body 51 having an opening, and a lid portion 52 provided on the case body 51 so as to be able to open and close the opening of the case body 51. The case body 51 and the lid portion 52 of this embodiment are formed from resin (or may be metal, etc.).

[0042] Like the carton body 91, the case body 51 is a box-shaped member that opens upward. The case body 51 has a side wall 511 that forms the side (front side) from which the wrap is pulled out, a bottom, left and right side surfaces, and a rear side surface. An extension 511a that extends rearward is formed at the upper end of the side wall 511. The extension 511a has the function of preventing the wrap roll 90 from popping out and, like the attachment assisting portion 23, the function of a charging promoting portion. In addition, attachment assisting portions (flanges) that protrude inward from the upper ends are formed on both the left and right side surfaces of the case body 51.

[0043] Like the lid 92, the lid 52 has a top surface, left and right side surfaces, and a pressing side surface 521 which is the front side surface. The top surface of the lid 52 is connected to the rear side surface of the case body 51 in a manner that allows it to be bent. The lid 52 is formed integrally with the case body 51. The basic shapes of the case body 51 and the lid 52 are the same as those of the carton body 91 and the lid 92, and the description thereof can be referred to.

[0044] A plate-shaped attachment portion 3 is provided on the surface (outer surface) of the side wall portion 511, which utilizes the charged state of the wrap pulled out from the case body 51 to attach the electrostatically charged wrap. The attachment portion 3 has the function of attaching the wrap and the function of reinforcing the main body. The configuration of the attachment portion 3 is similar to that of the attachment portion 3 of the wrap holder 1, so a description thereof will be omitted. The side wall portion 511 is provided with a knob auxiliary portion 4 which extends downward and forward from the base end portion 41 located in the recess 3a of the attachment portion 3. The configuration of the knob auxiliary portion 4 is similar to that of the wrap holder 1, so a description thereof will be omitted. A blade 93 for cutting the wrap is provided on the front lower end portion of the lid portion 52 (i.e., the lower end portion of the pressing side surface 521) and / or the front lower end portion of the case body 51.

[0045] The wrap case 5, which includes the attachment portion 3 and the gripping assist portion 4, also achieves the same effects as the wrap holder 1. Furthermore, with the wrap case 5, the case itself can be reused, so when the wrap runs out, only the wrap roll 90 inside needs to be purchased, thereby reducing the environmental impact. As an example, the case body 51 and the lid portion 52 are made of polypropylene, and the attachment portion 3 is made of acrylic. For the materials of the case body 51 and the lid portion 52, please refer to the above description of the holder body 2, and for the attachment portion 3, please refer to the description of the attachment portion 3 of the wrap holder 1.

[0046] (Summary of wrap case configuration) The wrap case 5 of this embodiment is a case-like wrapping device that houses a wrap roll 90 around which wrap is wound, and includes a box-shaped case body 51 with an opening, and a lid 52 attached to the case body 51 so as to open and close the opening. A plate-shaped attachment portion 3 is provided on the surface of a side wall 511, which is the side of the case body 51 from which the wrap is pulled out, to attach the electrostatically charged wrap pulled out of the case body 51 by utilizing the charged state of the wrap. If the direction from the bottom surface of the case body 51 toward the opening is defined as "upward," and the side perpendicular to the side wall 511 on which the attachment portion 3 is provided is defined as "forward," a blade 93 for cutting the wrap is provided at the front lower end of the lid 52 and / or the front lower end of the case body 51. The attachment portion 3 is provided with a recess 3a that is recessed upward. The side wall 511 is provided with a gripping assisting portion 4 having a base end 41 located within the recess 3a and two spaced apart protrusions 42, 43 extending downward and forward from the base end 41. At least a portion of each of the protrusions 42, 43 is located forward of the surface of the attachment portion 3.

[0047] (engaging claws) 7 to 10, the pressing side surface 521 constituting the front side surface of the lid portion 52 of the wrap case 5 of this embodiment is formed with an engagement claw 6 that protrudes rearward and engages with the attachment portion 3 (for example, the underside of the attachment portion 3) when the lid portion 52 is closed (see FIG. 10). The engagement claw 6 engages (in the vertical direction) with the bottom surface of the recess 3a when the lid portion 52 is closed. Note that the back surface of the pressing side surface 521 is shown in FIG. 7.

[0048] The engagement claw 6 is formed in a position facing the bottom surface of the recess 3a when the lid 52 is closed. In other words, the engagement claw 6 is formed so as to be located slightly below the bottom surface of the recess 3a when the lid 52 is closed. The engagement claw 6 is formed, for example, by bending a portion of the pressing side surface 521 backward. Like the knob assisting part 4, the base end of the engagement claw 6 is elastically deformable.

[0049] When the lid 52 is closed, the plate thickness of the attachment portion 3 causes the engagement claw 6 to catch on the bottom surface of the recess 3a. This prevents the lid 52 from opening naturally (slightly floating), improving the stability of the plastic wrap case 5 when not in use and preventing deterioration of the design. Furthermore, when the plastic wrap case 5 is gripped and the pressing side surface 521 is lightly pressed during use, the position of the engagement claw 6 changes (and / or elastically deforms), and the engagement with the recess 3a is released. This allows the lid 52 to be opened smoothly. From the viewpoints of main body reinforcement function and engagement function, the thickness of the attachment portion 3 is preferably 1 mm or more.

[0050] The engagement claw 6 of this embodiment is formed by bending a portion of the pressing side surface 521 (made of resin) backward. Therefore, a through-hole 521a in the shape of the engagement claw 6 is formed in the pressing side surface 521. The upper portion of this engagement claw 6 is a portion cut from the pressing side surface 521, and the lower portion forms a base end portion 61 that connects to the pressing side surface 521. The engagement claw 6 is bent at the base end portion 61 and extends backward and upward. This allows the bending angle of the base end portion 61 to be 90 degrees or less, suppressing a decrease in the durability and angle retention force of the base end portion 61. Furthermore, from the perspective of the upward pressing force and elastic deformation of the engagement claw 6, the engagement and release operations are relatively easy.

[0051] The width (left-right length) of the engagement claw 6 is smaller than the width of the bottom surface of the recess 3a. The engagement claw 6 is formed in a flat plate shape. When the lid portion 52 is closed, the tip of the engagement claw 6 abuts against and presses against the bottom surface of the recess 3a, thereby engaging it. In other words, the engagement claw 6 is formed in a position where the tip abuts against and presses against the bottom surface of the recess 3a when the lid portion 52 is closed.

[0052] The light locking of the lid portion 52 by the engaging claw 6 prevents the lid portion 52 from lifting up, even in a configuration in which the knob auxiliary portion 4 presses the lid portion 52 forward and upward. The presence of the knob auxiliary portion 4 may make the lid portion 52 more likely to lift up when not in use, but the engaging claw 6 can prevent this lifting. This configuration also improves the degree of freedom in the shape and inclination angle of the knob auxiliary portion 4, and can also accommodate, for example, deformation of the knob auxiliary portion 4 toward the front. In this way, the engaging claw 6 is particularly effective in a configuration in which the knob auxiliary portion 4 is included. When the knob auxiliary portion 4 presses the lid portion 52, the engaging claw 6 attempts to move upward, but it engages with the bottom surface of the recess 3a and stops.

[0053] The engaging claw 6 can also be applied to a wrap case that does not have the auxiliary grip part 4. In this case, the same effect as above, such as improved stability, is achieved. The engaging claw 6 may be formed so as to engage with any part of the underside of the attachment part 3 (including the bottom surface of the recess 3a). The engaging claw 6 may be formed as a separate member from the lid part 52.

[0054] Furthermore, the engaging claw 6 may be formed to engage with the knob auxiliary part 4. In this way, when the lid part 52 is closed, the engagement between the two acts to slightly pull the knob auxiliary part 4 forward, making it possible to suppress rearward movement of the knob auxiliary part 4 due to, for example, deterioration over time. The engaging claw 6 may be formed to engage with the base end part 41, for example, the bottom surface (concave bottom surface) between the two protruding parts 42, 43. Because the engaging claw 6 engages with the attachment part 3 or the knob auxiliary part 4, there is no need to form an engaged part on the case side, which is advantageous in terms of manufacturing costs.

[0055] (others) The present invention is not limited to the above embodiment. For example, the blade 93 may be provided at the front lower end of the carton body 91 instead of the lid 92. In this case, for example, a through groove may be formed at the front lower end of the holder bottom 21 so that the blade 93 is exposed to the outside. The front lower end of the case body 51 may be formed with a through groove that allows the blade to be exposed to the outside. In this case, the wrap case 5 accommodates a wrap carton with a blade provided at the front lower end of the carton body 91, and the blade formed on the carton body 91 is exposed from the through groove. This wrap case 5 can have two blades: the blade 93 on the pressing side surface 521 and the blade of the carton body 91 exposed from the through groove. This allows the user to select one of the two blades to cut the wrap (for example, in a preferred cutting style).

[0056] The knob assisting portion 4 may be formed as a separate member from the side wall portions 22, 511. The knob assisting portion 4 may have another protrusion in addition to the protrusions 42, 43. That is, the knob assisting portion 4 may have three or more protrusions spaced apart from one another, for example, like the shape of a fork on a tableware. The knob assisting portion 4 may have at least two protrusions 42, 43. For example, it is preferable that the distance between the two most distant protrusions is 10 mm or more (more preferably 15 mm or more). Furthermore, the knob assisting portion 4 may have a protrusion between the two protrusions that protrudes shorter or longer than the protrusions.

[0057] Furthermore, the protrusions 42, 43 may be curved, for example, in an arc shape, so as to bulge or recess. For example, if the protrusions 42, 43 are curved in a convex shape toward the front, the top of the convex shape, rather than the tip, may be located forward of the surface of the attachment portion 3. In this way, it is sufficient that at least a portion of the protrusions 42, 43 is located forward of the surface of the attachment portion 3. Each of the protrusions 42, 43 may be wavy, for example, with multiple projections and recesses formed in the front-to-rear direction. A configuration in which each of the protrusions 42, 43 is inclined so that the tip is more forward is advantageous in terms of ease of gripping by the user.

[0058] Furthermore, knob assisting portion 4 may be composed of two or more extending members (e.g., rod-shaped members, flat rectangular plates) spaced apart from one another and projecting directly from side wall portion 22, 511. In this case, a portion of side wall portion 22 serves as the base end, and the portion that curves from the base end and extends downward and forward can be considered to be the protruding portion. In this case as well, knob assisting portion 4 can be considered to have a concave shape.

[0059] Furthermore, a plurality of recesses 3a and grip assistant portions 4 may be formed for one wrap holder 1 or wrap case 5. Furthermore, the wrap holder 1 or wrap case 5 may be formed by cutting, folding, and / or gluing from a single resin sheet on which cuts or creases are formed along the shape.

[0060] Furthermore, particularly when the case body 51 and the lid 52 are made of metal and the attachment portion 3 is made of resin, the attachment portion 3 may be configured to press the case body 51 (side wall 511) and the lid 52 (pressing side surface 521) when the lid 52 is closed. In other words, the attachment portion 3 may be configured so that at least a portion thereof is compressed in the front-to-rear direction by the side wall 511 and the pressing side surface 521 when the lid 52 is closed. This allows the lid 52 to remain closed even without the engagement claw 6. In other words, the attachment portion 3 also functions as a stopper for the lid 52. The attachment portion 3 also strengthens the adhesion of the wrap to the attachment portion 3. When the attachment portion 3 is flat, the thickness of the attachment portion 3 is greater than the distance between the side wall 511 and the pressing side surface 521 when the lid 52 is closed. In other words, the lid 52 is closed while being pressed by the attachment portion 3. In such a configuration, it is preferable that at least a part of the surface of the attachment portion 3 has a convex arc shape that convex forward, as shown in Fig. 11. Alternatively, the surface of the attachment portion 3 may have a convex portion that is compressed in the front-to-rear direction when the lid portion 52 is closed. Alternatively, the surface of the attachment portion 3 may have an uneven surface, and the back surface of the pressing side surface 521 may have an uneven surface that engages with the uneven surface.
