Abstract

The present invention is to provide a box for containing rolled film capable of inhibiting the damage of elongated article and a storage box containing a rolled film. The box for containing rolled film is provided with a main body portion 10 for housing a rolled film rolled with an elongated article, and a cover portion for covering the opening surface of the main body portion 10. The front plate 12 of the main body portion 10 is formed with a locking mechanism 50 for locking the elongated article in the coverage region W when the cover portion is closed. The coverage region W is divided into three main areas of M1, M2, M3 and a central area C. The locking mechanism 50 is constituted such that in the area surrounded by the outer edge of a portion including the gap 51g, the first area M1 is greater than the second area M2 and the third area M3, and the maximum height of the locking mechanism 50 of the first area M1 is greater than one-half of the first area M1's own maximum height. Moreover, when the central portion in the width of the elongated article is caught for pulling out the elongated article from the locking mechanism 50, because the locking force becomes relatively small at the end portion where the tension in the longitudinal direction becomes large, damage to the elongated article is inhibited.

Description

Winding body storage box and storage box with winding body

The present invention relates to a wound storage case and a storage case containing the wound body, and more particularly to a wound storage case and a wound body which can suppress damage of an elongated object drawn from the wound body Storage box.

Fresh-keeping films for foods that are wrapped in ingredients, dishes, or foods that are wrapped with dishes such as dishes are being widely used. Typically, the wrap film for food is stored in a long rectangular parallelepiped (storage box) in a long plastic film (rolled body) wound in a roll shape, and the film at the front end is pulled out from the drum by a necessary length during use. The cutting blade on the lid of the container is cut. In order to prevent the cut end portion of the drawn film from being wound back into the container, a temporary fixing portion for locking the film after the cutting is provided in a portion covered by the cover plate on the outer upper side of the front surface of the container. In addition, the storage of the wrap film is improved in such a manner that the shape of the side end portion of the cut film is linearly formed in order to prevent the cutting performance of the film which has been pulled out from the side end thereof from being lowered. The box has a configuration in which the temporary fixing portion is disposed at a position 3 to 6 mm from the upper edge of the front plate until the position of the front end of the cutting tool at the front end of the cover sheet, and the shape is made along the box. The strip body having a length extending over the entire length is provided at a central portion of the length of the strip body and at three end portions of the length, and a slit portion having a width of substantially 1/2 to 3/4 of the strip width and a length corresponding to the longitudinal direction is provided. As a result, the tops of the two raised portions are formed toward the bottom plate side of the casing (for example, refer to Patent Document 1).

[Patent Document 1] Japanese Patent Laid-Open No. Hei 7-33139 (paragraph 0009, Figs. 1, 2, etc.)

However, in the storage box of the wrap film of Patent Document 1, since the length of the slit portion at the center portion of the length of the strip is longer than the length of the slit portion at both end portions of the length, the sheet is peeled off before the temporary fixing portion is formed. When the film is temporarily fixed, if the center of the width of the film is grasped and the film is to be removed, the component in the longitudinal direction of the tension applied to the film of the two convex portions having the strong adhesion force becomes large. There is a rupture of the membrane.

In view of the above problems, an object of the present invention is to provide a wound body storage box capable of suppressing damage of an elongated object and a storage case containing the wound body.

In order to achieve the above object, the wound body storage case according to the first aspect of the present invention includes, as shown in Figs. 1, 2, and 5(B), a main body portion 10 that accommodates an elongated object 91f.

The region, that is, the specific position of the covering region W (refer to FIG. 2), actually forms the locking mechanism 50 for locking the elongated object 91f along the front end edge 19; the covering region W Parallel to the direction of the front end edge 19, that is, the longitudinal direction D, is divided into the cover sheet 22 and the front panel when the central portion in the longitudinal direction D of the cover sheet 22 is pressed toward the front panel 12 in a state where the cover portion 20 is closed. 12 The central region C in a specific range in which the contact range is the reference, and the main region M closer to the side plate 15 side than the central region C; the main region M is further divided into three in the longitudinal direction D, thereby from the central region The C side-to-side panel 15 side is sequentially divided into a first region M1, a second region M2, and a third region M3; and a portion of the first region M1 that is surrounded by the outer edge of the locking mechanism 50, that is, the first locking region Q1 ( Referring to the area of FIG. 5(B)), the area of the second locking region Q2 (see FIG. 5(B)), which is a portion surrounded by the outer edge of the locked mechanism 50 in the second region M2, and the third region are larger than the area. The portion of the M3 that is surrounded by the outer edge of the locking mechanism 50, that is, the area of the third locking region Q3 (see FIG. 5(B)), and the direction orthogonal to the end edge of the front plate, that is, the height direction At the time of observation, the maximum distance HQ1 in the height direction of the first locking region Q1 (see FIG. 5(B)) is 1/2 or more of the maximum distance HM1 (see FIG. 5(B)) in the height direction of the first region M1. . Here, the "outer edge of the locking mechanism" means a boundary which can be regarded as a contour of the locking mechanism as a whole by replenishing the gap even if there is a gap in which the locking mechanism is not formed partially. Further, typically, the main body portion is formed in a rectangular parallelepiped shape, and the opening surface is formed on one of four rectangular surfaces parallel to the axis of the winding body when the winding body is housed in the main body portion, and the rear plate is formed. One of the two rectangular faces orthogonal to the opening surface forms a rectangular surface facing the rear plate, and the pair of side plates are formed at right angles to the four rectangular faces to form a rectangular parallelepiped end face.

In such a configuration, the center portion of the longitudinal direction of the elongated object (the width direction of the elongated object) is grasped, and the elongated object is pulled out from the wound body, and when the elongated object is peeled from the locking mechanism, the length direction is The locking force at the end portion in the longitudinal direction of the elongated object whose tension is increased is relatively small, so that damage of the elongated object can be suppressed.

Further, the wound body storage case according to the second aspect of the present invention is formed in the first region M1 in the wound body storage case according to the first aspect of the present invention, as shown in Fig. 3 (for example, see Fig. 2). The locking mechanism 50 is configured to be intermittently interposed by a plurality of gaps 51g extending in the direction in which the longitudinal direction D intersects, and the locking mechanism 50 is not formed.

When it is configured as such, it is possible to further suppress the difficulty in pulling out.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or equivalent components are denoted by the same or like numerals, and the description thereof will be omitted.

First, the wrap film case 1 as a wound body storage case in the embodiment of the present invention, and the wrap film roll 91r as a wound body are accommodated in the wrap film case 1 as a wrap-around body. The box 100 of the plastic wrap containing the storage box. Fig. 1(A) is a perspective view of a case 100 containing a wrap film, and Fig. 1(B) is a partial side cross-sectional view of the wrap case 1. Fig. 1(A) shows the open state. The wrap film roll 91r is formed by winding the wrap film 91f as a film-shaped elongated product around the axis 91a around the cylindrical core to form a roll. In the following description, when the appearance shapes of the wrap film roll 91r and the wrap film 91f are not distinguished, they are collectively referred to as "wrap film 91". In the present embodiment, the wrap film 91f is formed to have a thickness of 5 to 20 μm using polyvinylidene chloride as a raw material. The wrap film cassette 1 includes a main body portion 10 that houses the wrap film roll 91r, and a lid portion 20 that is coupled to the main body portion 10.

The main body portion 10 is a box in which a rectangular parallelepiped having a size of an unused wrap film roll 91r is placed, and one surface of the elongated surface is an open surface 10h. The main body portion 10 is formed to have a gap that does not prevent the unused wrap film roll 91r from rotating around the axis 91a, and is formed to be as small as possible. In the present embodiment, it is formed to have a width of 44 mm and a height of 44. Mm, length 310 mm. The main body portion 10 has a front plate 12, a bottom plate 13, a rear plate 14, and two side plates 15 constituting end faces of the cube, which are combined with the opening surface 10h to form a side surface of the rectangular parallelepiped. The bottom plate 13 is opposed to the opening surface 10h. The front plate 12 and the rear plate 14 are orthogonal to the opening Face 10h and bottom plate 13. The side panels 15 are typically formed in a square shape, but may also be rectangular in shape having different lengths. In the following description, the state in which the bottom plate 13 is placed on the horizontal surface is used, and the bottom plate 13 side is downward and the opening surface 10h side is upward.

At a central portion of the upper end of the side plate 15, a projection 15p formed by folding a small piece extending upward by about 3 mm is provided. There are two protrusions 15p, and are respectively disposed at the upper ends of the side plates 15. Further, the main body portion 10 is provided on the front plate end side 19 with the sub-plate 16 connected to the front plate 12 (see Fig. 1(B)). The front end edge 19 is an end side of the front plate 12 at a portion where the front plate 12 and the opening surface 10h intersect, and also serves as a boundary between the front plate 12 and the sub-plate 16 in the present embodiment. The sub-board 16 is substantially the same size as the front plate 12 but is not connected to the bottom plate 13 and is disposed further inside the main body portion 10 than the front plate 12. The end edge of the side of the bottom plate 13 of the sub-board 16 is followed by the front plate 12 in the longitudinal direction.

The lid portion 20 is a member that blocks the opening surface 10h of the body portion 10. The lid portion 20 has a cover 21, a cover sheet 22, a cutting blade 23, and a side cover sheet 25. The cover plate 21 is a rectangular flat member having substantially the same size as the opening surface 10h, and is a rectangular parallelepiped that can close the main body portion 10 by covering the cover 21 with the opening surface 10h. The cover plate 21 and the opening surface 10h are substantially the same size, and the cover plate 21 is enlarged corresponding to the thickness of the cover sheet 22 and the thickness of the side cover sheet 25, so that the gap is formed so as not to hinder the opening and closing of the cover portion 20. Big situation. One of the longitudinal directions of the cover plate 21 is connected to the rear end edge 18 of the body portion 10. In other words, the body portion 10 and the cover plate 21 are connected via the rear plate end edge 18. The rear plate end 18 is the end side of the rear plate 14 where the rear plate 14 and the opening surface 10h intersect. The cover plate 21 is configured to be rotatable relative to the main body portion 10 with the rear plate end side 18 as a rotation axis.

The cover sheet 22 is disposed in such a manner as to be orthogonal to the cover 21 via the bent side 21f, and extends toward the bottom plate 13 when the cover portion 20 is closed. The height of both ends of the direction in which the axis 91a of the wrap film roll 91r extends (hereinafter referred to as "axial direction D") (the length of the short side direction of the rectangular front plate 12) is about the short side direction of the front plate 12 The length of the central portion of the axial direction D is 1/2, which is about 3/4 of the length of the short side direction of the front plate 12. Opposite to the side The end edge 22t before 21f is formed in such a manner that as the center from the axial direction D moves toward the respective end portions, the distance between the bent side 21f and the front end side 22t in the direction orthogonal to the axial direction D becomes short. According to this configuration, the end 22t before the bent side 21f is formed in a V shape. The cover sheet 22 is superposed on the outer side of the front panel 12 along the front panel 12 when the cover portion 20 is closed, and covers the upper portion of the front panel 12 in a pentagonal shape. The cover sheet 22 is configured such that the length in the axial direction D is slightly longer than the length of the front panel 12 and longer than the width of the wrap film 91 accommodated in the main body portion 10. Thereby, the cover sheet 22 is configured such that the wrap film 91f pulled out from the main body portion 10 can be sandwiched between the wrap film 91f and the front plate 12 across the entire width thereof. A cutting blade 23 for cutting the wrap film 91f is attached to the front end 22t of the cover sheet 22. The cutting blade 23 has its blade tip exposed from the front end 22t and is V-shaped along the front end 22t.

The side cover sheets 25 are orthogonal to both the cover 21 and the cover sheets 22. The side cover sheets 25 are provided at both ends of the cover 21 (covering sheet 22) in total. The side cover sheet 25 has a basic shape in which the long side is the same as the short side length of the cover plate 21, and the height of the short side and the central portion of the cover sheet 22 (the shortest distance from the V-shaped front end to the bent side 21f) is substantially A rectangle of the same length. The side cover sheet 25 is fixed to the engaging piece 22j connected to the cover sheet 22 by an adhesive. A recess 25d is formed between the engaging piece 22j and the cover 21 on the inner side of the side cover piece 25. When the lid portion 20 is closed, the projection 15p provided at the upper end of the side panel 15 is fitted in the recess portion 25d. The cover portion 20 configured as described above is closed to the opening 10h of the main body portion 10 when the cover portion 20 is closed, and the cover sheet 22 covers the upper portion of the front plate 12.

In the present embodiment, the main body portion 10 and the lid portion 20 are formed of corrugated cardboard having a thickness of about 0.45 to 0.7 mm. Therefore, the wrap film cassette 1 has elasticity. In the present embodiment, for the sake of convenience of explanation, the main body portion 10 and the lid portion 20 are separated from each other from the viewpoint of function. However, the main body portion 10 and the lid portion 20 are formed by cutting one piece of base paper and assembling them into one body. The surface of the main body portion 10 and the lid portion 20 is printed with a design that is intended to be purchased by a consumer, and subjected to surface treatment such as waterproof processing. Further, the wrap film cassette 1 is attached to the upper portion of the front plate 12, and the surface of the front plate 12 is cut out to form a flap 12f which is separated from the sub-plate 16 and raised outside the main body portion 10. That is, the front plate 12 is structured It becomes included with the flap 12f.

Here, the details of the fin 12f will be described with reference to Fig. 2 in conjunction with Fig. 1. 2 is a front elevational view of the body portion 10 of the wrap case 1. In the present embodiment, the fin 12f is provided along the front end edge 19 in the central portion so as to sandwich the central portion C located at the center in the longitudinal direction of the front plate 12 (the same direction as the axial direction D). C is closer to the outer side. The "Central Area C" is defined as follows. The portion of the front panel 12 covered by the cover sheet 22 when the lid portion 20 is closed is referred to as "coverage area W". In Fig. 2, a portion surrounded by the imaginary boundary line 12b, the front plate end side 19, and the side plates 15 indicated by a chain double-dashed line is a cover area W. The cover area W is divided into three in the longitudinal direction (axial direction D) of the front plate 12, and the center area C in the center, and the "main area M" on both sides. In other words, the two main regions M are formed such that the central region C is sandwiched therebetween. The width of the central portion C (distance in the longitudinal direction) is such that the centroid of the cover sheet 22 (the portion of the cover sheet 22 near the apex of the V-shaped end of the front end 22t) is pressed against the front plate 12 in a state where the cover portion 20 is closed. In any case, the value is within a range of ±20% based on the distance of the range in which the cover sheet 22 is in contact. For example, when the rectangular core of the cover sheet 22 is pressed toward the front plate 12 in a state where the cover portion 20 is closed, when the cover sheet 22 is in contact with the front plate 12 in a range of 40 mm, the width of the central portion C can be 32. Make any decision between mm~48 mm. At this time, the elastic wrap film case 1 changes the range in which the cover sheet 22 comes into contact with the front plate 12 according to the pressing force of the cover sheet 22 toward the front plate 12, but when the central region C is defined, When the unused core roll 91r is stored in the main body portion 10 and the center of the cover sheet 22 is pressed toward the front plate 12, the front plate 12 is blocked by the wrap film roll 91r in the main body portion 10 without The distance in the longitudinal direction of the range in which the cover sheet 22 is in contact with the front plate 12 when moving toward the rear plate 14 side serves as a reference for defining the width of the central portion C. In the present embodiment, the width of the central portion C is defined as 40 mm, which is approximately 13% of the width (distance in the longitudinal direction) of the front plate 12, but the width of the central portion C may be 20 mm to 70 mm. It is preferably 30 mm to 50 mm, or 6% to 25% of the width of the front plate 12 (distance in the longitudinal direction), preferably in the range of 10% to 16%.

For the convenience of the description, in the front view (see FIG. 2), the two flaps 12f provided for sandwiching the central region C have the left flap 12f as the left flap 12fA and the central region C. The flap 12f on the right side serves as the right flap 12fB. The left flap 12fA and the right flap 12fB correspond to the first flap and the second flap, respectively. Hereinafter, when the common configuration of the left flap 12fA and the right flap 12fB is described, it is simply referred to as "wing 12f". Further, the side panel 15 close to the left flap 12fA may be referred to as a left side panel 15A (first side panel), and the side panel 15 close to the right flap 12fB may be referred to as a right side panel 15B (second side panel), and the side panel 15 is collectively referred to as a front panel 15 . The left flap 12fA is formed by a size included in the main region M on the left side. The right flap 12fB is formed by a size included in the main region M on the right side.

The outline of the left flap 12fA is constituted by a tangent 12cA formed in the plane of the front panel 12, and a front end edge 19. The tangent line 12cA is a line that cuts a portion of the front panel 12. The tangent line 12cA is closer to the left side panel 15A than the central portion C, from the point 12cAN on the end edge 19 of the panel near the central region C, through the in-plane of the front panel 12, to the edge end 19 of the panel before the left side panel 15A. The method of the point 12cAS is formed by cutting the inside of the front plate 12. In the point 12cAN, when the wrap film 91f is cut, the wrap film 91f does not have a degree of sliding such that the slit of the wrap film 91f becomes untidy, and is located in the vicinity of the center area C. . The point 12cAS is located slightly closer to the substantially central portion C than the left end of the wrap-out cling film 91f, but may be located between the left end of the wrap film 91f and the left side plate 15A. The left end of the left flap 12fA (the position of the point 12cAS) is slightly closer to the left end of the wrap film 91f than the substantially central region C, and is a state in which the left flap 12fA and the cover sheet 22 can be used to cut the wrap film 91f. The left end of the left flap 12fA does not reach the left end of the wrap film 91f within a range in which the wrap film 91f is held without being loosely cut. In this state, the state in which the left end of the left flap 12fA coincides with the left end of the wrap film 91f and the state in which the left end of the left flap 12fA is closer to the outer side than the left end of the wrap film 91f are collectively referred to as the actual extension of the left flap 12fA to the wrap film 91f. Left end. When the left end of the left flap 12fA is formed closer to the central portion C than the left end of the wrap film 91f, the end of the front panel 12 in the axial direction D can be suppressed. The strength of the body portion 10 around the portion is lowered. In the present embodiment, the left end of the left flap 12fA is formed closer to the center region C by 15 mm than the left end of the front panel 12 in the axial direction D, but may be formed closer to the center region C by 10 mm or 5 mm. . The maximum length in the height direction of the left flap 12fA is approximately 1/2 of the length in the height direction of the front panel 12. In the present embodiment, the side of the lower side of the left flap 12fA is formed such that it is slightly closer to the front end edge 19 and then away from the front end edge 19 when the central portion C side of the axial direction D is advanced toward the left side plate 15A side. A smooth curve. In other words, the left flap 12fA has its central portion recessed upward from the both ends. The left flap 12fA is formed to be covered by the cover sheet 22 when the cover portion 20 is closed without being exposed to the outer surface.

Since both ends 12cAN and 12cAS of the tangent 12cA constituting the outline of the left flap 12fA reach the front end edge 19, the left flap 12fA can be favorably held up from the sub-plate 16. Further, in the case where the left flap 12fA is excessively lifted from the front surface of the front panel 12, the degree of warping can be adjusted by slightly moving the ends of the tangent 12cA slightly away from the front end edge 19. The longer the distance between the end of the tangent 12cA and the front end edge 19, the smaller the amount of lift of the left flap 12fA, for example, the amount of lift when the distance is 5 mm is smaller than when the distance is 3 mm. The left flap 12fA is formed such that the sub-plate 16 is connected by the front end edge 19, so that it does not fall off from the main body portion 10 even if it is cut by the cutting line 12cA. Further, the left flap 12fA is configured to rotate the front end edge 19 as a rotation axis by connecting the sub-plate 16 to the front end edge 19.

On the surface of the left flap 12fA, the stopper 50 as the locking mechanism is actually formed at a specific position along the front end edge 19. In the present embodiment, the stopper 50 is formed by applying a UV varnish. The UV varnish forming the stopper 50 can be attached to the wrap film 91f, but has a property that paper or dust does not adhere. Moreover, the wrap film 91f adhered to the stopper 50 strongly adheres to the direction parallel to the attachment surface (shear direction), but adheres weakly to the direction perpendicular to the attachment surface (the direction away from the attachment surface). That is, the stopper 50 is configured such that when the wrap film 91f is pulled out along the front plate 12 in the direction in which the wrap film 91 is pulled out from the main body portion 10, it adheres to the wrap film 91f, so that the wrap film 91f does not Move in the pull-out direction P; When the wrap film 91f is pulled out in a direction away from the attachment surface, the wrap film 91f is peeled off. The stopper 50 "actually formed along the front end edge 19" means a normal state when the wrap film 91f is pulled out, that is, in a state in which it can be brought into contact with the front end edge 19 but lifted from the front panel 12. When it is out, the state of the stopper 50 formed in the vicinity of the front end edge 19 is not in contact with the plastic wrap 91f which is pulled out.

The specific position at which the stopper 50 is formed will be described by dividing the viewpoint into the axial direction D and the height direction (the short side direction of the front panel 12). In the present embodiment, in the axial direction D, the stopper 50 is formed substantially across the entire length of the axial direction D of the left flap 12fA. Here, "actually formed over the entire length of the axial direction D of the left flap 12fA" is not strictly required to be continuously formed, but means that the wrap film 91f can be locked when the wrap film 91f is cut to avoid the wrap film. In the range in which the movement of 91f is prevented from being appropriately cut, a portion which is not formed intermittently is allowed, and a portion which is not formed at both ends is allowed.

The specific position at which the stopper 50 in the height direction is formed varies depending on the area. In order to facilitate the description, the main regions M are further divided into three equal parts in the axial direction D, and are sequentially divided into the first region M1, the second region M2, and the third region from the central region C side toward the side plates 15 side. M3. The division of the first region M1, the second region M2, and the third region M3 is formed by line symmetry in which the front plate 12 is divided into two halved imaginary straight lines 12v. Further, the coverage area W, the central area C, and the main area M, and the first area M1, the second area M2, and the third area M3 are imaginarily divided for convenience of explanation, regardless of whether or not the respective boundary lines actually appear. On the front panel 12. In the present embodiment, the maximum distance of the stopper 50 in the height direction is the largest in the first region M1, and is smaller in the order of the second region M2 and the third region M3.

When the stopper 50 is described in more detail, in the present embodiment, the basic shape of the lower profile is the height of the stopper 50 as it advances from the boundary between the central region C and the first region M1 toward the left side plate 15A side. The distance of the direction (hereinafter, also referred to as "height" for short) is gradually increased to 2/3 of the length of the axis direction D of the first region M1. The right position reaches the maximum, and gradually becomes smaller as it is reversed, and advances from the boundary between the first region M1 and the second region M2 to about 1/3 of the length of the axial direction D of the second region M2 to the left flap. The ends of 12fA are formed to be substantially the same height. The shape of the stopper 50 is formed in a circular arc shape which is convex downward in the vicinity of the central portion C, and is formed in an elongated strip shape in the vicinity of the left side plate 15A.

In the present embodiment, the maximum distance of the stopper 50 in the height direction is actually formed to be approximately 2/ of the maximum distance of the first region M1 in the height direction (the height of the boundary line between the first region M1 and the center region C). 3. The height of the strip-shaped stopper 50 formed in the third region M3 is actually formed to be substantially 0.5 times the maximum distance of the stopper 50 in the height direction. That is, when the size of the stopper 50 is different from that of the embodiment, the maximum distance of the stopper 50 in the height direction may actually be 1/2 or more of the maximum distance of the first region M1 in the height direction. The average height of the strip-shaped stopper 50 formed in the third region M3 may actually be formed to be 0.7 times, preferably less than 0.6 times, the maximum distance of the stopper 50 in the height direction. The fact that the stopper 50 is formed "actually" in the height direction means that the function of preventing the wrap of the wrap film 91f or improving the function of the stopper 50 such as the cut-off property can be allowed to intermittently exist without the stopper 50 being formed. section.

Further, in the present embodiment, a gap 51g in which the stopper 50 is not formed is formed in the arcuate portion of the stopper 50. The gap 51g is a vertically long person extending in the height direction (the direction in which the wrap film 91f is pulled out), and is formed in plural in the axial direction D with an interval therebetween. In the present embodiment, the gap 51g is formed so as not to separate the stopper 50 formed along the front end 19 of the front plate, and to retain the band of the stopper 50 of about 3 mm on the side of the front end 19 side. Further, in the present embodiment, the stopper 50 is formed on the surface of the front plate 12 which is closer to the outer side than the left flap 12fA. In the present embodiment, the stopper 50 formed in the main region M between the center region C and the left side plate 15A is formed such that the area of the first region M1 is twice or more the area of the third region M3, and is larger than 2 Area M2 area. In other words, the stopper 50 is formed such that the vicinity of the center area C is large, and the vicinity of the left side plate 15A is small.

Referring to Figure 3, a summary of the shape of the stop 50 formed on the left flap 12fA described so far is shown. Fig. 3 is a partial front elevational view of the periphery of the left flap 12fA of the embodiment. The stopper 50 is formed by an arcuate portion 50a on the central portion C side and a strip portion 50b on the side of the left side plate 15A. A gap 50H of about 2 mm is continuously formed between the entire stopper 50 and the front end edge 19. The interval between the front end of the largest portion of the height of the arcuate portion 50a and the tangent 12cA is formed to be about 4 mm. The gap width 51W which is the width of the gap 51g formed in the arcuate portion 50a is approximately 3 mm in common in each gap 51g. The width of the arcuate portion 50a which is formed into a meandering portion by forming a plurality of gaps 51g, that is, the width 50 width 50W is also about 3 mm. The height of the substrate which is formed in a meandering shape on the side of the front end 19 side and which is extended in the axial direction D, that is, the base height 50aE is uniformly formed to be about 3 mm. The height of the end portion of the left side plate 15A of the belt portion 50b, that is, the belt end height 50bE is about 3 mm, and the height of the belt portion 50b at the boundary with the arcuate portion 50a, that is, the belt end height 50bC is about 5 mm, banded. The side of the tangent 12cA side of the portion 50b is formed in a straight line shape. Therefore, the height of the strip portion 50b is formed to increase little by little as the self-belt end moves to the center of the belt. Therefore, the height of the strip-shaped stopper 50 formed in the above-described third region M3 is referred to as an average height.

Returning to Fig. 2 and Fig. 1, the fin 12f will be described. The right flap 12fB has an imaginary straight line 12v as a shaft and is formed in line symmetry with the left flap 12fA. The point 12cBN and the point 12cBS of the right flap 12fB correspond to the point 12cAN and the point 12cAS of the left flap 12fA, respectively. In the right flap 12f, the stopper 50 is also formed in line symmetry with the stopper 50 formed on the left flap 12fA with the imaginary straight line 12v as an axis. Further, in the stopper 50, the central portion C is also formed to have a height along the front plate end side 19 at the same height as the base height 50aE.

With reference to Fig. 1 and Fig. 2, the function of the cartridge 100 containing the wrap film will be described. The function of the cling film cartridge 1 is explained as a function of the cartridge 100 containing the cling film. The unsealed case 100 containing the wrap film is attached to the front end of the cover sheet 22, and a cut piece (not shown) is connected to the through hole (not shown) on the front end side 22t, and the cut piece (not shown) is attached. In a few points Next to the front panel 12. When the wrap film 91 is used first, the dicing sheet (not shown) is cut by a perforation (not shown) while being peeled off from the front plate 12, and is separated from the cover sheet 22. By thus unsealing the wrap case 1, the lid portion 20 is in a state of being rotatable around the rear plate 18 with respect to the main body portion 10.

The unsealed case 100 containing the wrap film is provided with the wrap film 91 in the body portion 10. In the wrap film roll 91r, a pull-out seal (not shown) is attached to the front end of the wrap film 91f, and the front end of the wrap film 91f is self-worn film roll 91r by pulling out the pull-out seal (not shown). The peeling is performed so that the wrap film 91f can be easily pulled out. When the wrap film 91f is used, the wrap film 91f of a required length is pulled out from the wrap film roll 91r, and is cut by the cutting blade 23. At this time, the cover portion 20 is closed while the wrap film 91f has been pulled out by the necessary length, and the wrap film 91f is held by the front plate 12 and the cover sheet 22, and the centroid of the cover sheet 22 is pressed with the thumb. When the center of the cutting blade 23 is caught in the plastic wrap film 91f that has been pulled out, the case 100 with the wrap film is rotated about the axis 91a, even when the wrap film 91f is attached to the wrapped tableware or the like. It can be easily cut off, and is preferred.

When the wrap film 91f is pulled out and cut, the center portion in the width direction of the front end of the wrap film 91f is usually pulled out, and the lid portion 20 is directly closed without being changed, and the cutting is performed. In the middle portion of the cutting blade 23 from the center portion in the width direction of the wrap film 91f to the both end portions, the wrap film 91f is cut in the center portion of the width direction, and the wrap film 91f is cut and caught in the center portion in the width direction. The tension between the fingers at the front end of the wrap film 91f disappears, so that it is subjected to a force pulling toward the end portion that has not been cut. Therefore, when the front plate 12 and the cover sheet 22 are insufficient to hold the wrap film 91f, the wrap film 91f which has just been cut is close to the end portion, and wrinkles may occur, and the cut film may not be cut off intact. According to the wrap film cassette 1 of the present embodiment, the area of the stopper 50 formed in the first region M1 of the main region M which is close to the center portion in the width direction of the wrap film 91f is relatively large, so that the cut-off can be suppressed. The wrap film 91f near the central portion in the width direction is laterally slid. Further, since the fins 12f are formed in the main region M, the fins 12f assist the force of pressing the wrap film 91f toward the cover sheet 22 side, thereby contributing to suppressing the lateral direction of the wrap film 91f which has just been cut. slide. In addition, in the central area C, when the cover 20 is closed, When the cover sheet 22 is pressed against the front plate 12, since the cover sheet 22 comes into contact with the front plate 12, lateral slippage of the wrap film 91f which has just been cut can be suppressed. The effect of the above is particularly advantageous for a relatively long plastic wrap case of 250 mm or more like the wrap case 1 of the present embodiment in which the length in the axial direction D is formed to be 310 mm.

After being cut, the wrap film 91f sandwiched between the flap 12f and the cover sheet 22 is attached to the stopper 50, so that it can be prevented from being wound back toward the wrap film roll 91r. Further, when the cover film 20 is opened next time, when the lid portion 20 is opened, the flap 12f is lifted toward the outside of the main body portion 10, so that it adheres to the front end of the wrap film 91f formed on the stopper 50 of the flap 12f. The front panel 12 is also lifted from the outer side of the flap 12f so as to be easily grasped. In particular, since the wrap film cassette 1 does not form the flap 12f in the central region C, a gap is formed between the center region C and the wrap film 91f, so that the wrap film can be easily grasped by placing a finger in the gap. 91f. The central region C is located between the left flap 12fA and the right flap 12fB and corresponds to the central portion of the wrap film 91f in the width direction.

Here, the action of pulling out the wrap film 91f attached to the stopper 50 will be described with reference to Fig. 4 in conjunction with Figs. 1 and 2 . When the wrap film 91f caught between the left flap 12fA and the right flap 12fB is pulled out, first, the wrap film 91f is lifted away from the front panel 12, and peeled off from the stopper 50. At this time, the wrap film 91f adhered to the stopper 50 along the entire front end edge 19 and the axial direction D is attached to the cling film 91f and attached to the stopper 50. The tension T is applied to the imaginary line of any part of the cling film 91f. The tension T can be decomposed into a component Tp in the pull-out direction P and a component Td in the axial direction D. In the wrap film 91f attached to the stopper 50, the tension T of the portion near the center in the width direction is larger as the pull-out direction component Tp is larger and the axial direction component Td is smaller; the tension T is closer to the end portion. The smaller the pull-out direction component Tp is, the larger the axial direction component Td is. For example, the axial direction component Td of the tension T(E) acting on the end portion in the width direction of the wrap film 91f is larger than the tension T(F) acting on the portion closer to the center. Since the axial direction component Td generates a shearing force to the wrap film 91f, if the axial direction component Td is excessively large, the wrap film 91f may be broken. root According to the wrap film cassette 1 of the present embodiment, since the area of the stopper 50 formed in the third region M3 of the end portion in the width direction of the wrap film 91f is relatively small, the change of the axial direction component Td of the end portion can be suppressed. It is large, so that the damage of the wrap film 91f can be suppressed.

As described above, according to the wrap film cassette 1 of the present embodiment, the stopper 50 is configured such that the ratio of the area formed in the first region M1 to the area formed in the third region M3 is 2 or more, and is formed. The area in the second region M2 is smaller than the area formed in the first region M1. In this manner, since the formation area of the stopper 50 is larger in the first region M1 close to the central portion C and smaller in the third region M3 near the end portion, the wrap film 91f is cut from the center of the width toward both ends. In this case, it is possible to appropriately suppress the lateral sliding of the wrap film 91f which has just been cut, and it is possible to suppress an increase in the shearing force when the wrap film 91f is pulled out, thereby suppressing the damage of the wrap film 91f.

Further, in the stopper 50 of the wrap case 1 described above, the gap 51g formed in the arc-shaped portion 50a is filled with the strip-shaped base portion extending in the axial direction D on the side of the front plate end 19, but is filled. It can also be configured as follows.

Fig. 5 is a partial front elevational view showing the periphery of the left flap 12fA of the modified wrap film capsule 1A, wherein (A) is a view showing the stopper 50A, and (B) is a view showing the lock region Q. The stopper 50A in the deformed wrap film cassette 1A is different from the stopper 50 (see Figs. 2 and 3) of the wrap film cassette 1 in the following points.

First, the stopper 50A formed on the left flap 12fA, and the arc-shaped portion 50d (corresponding to the arc-shaped portion 50a (see FIG. 3) of the wrap case 1) will be described, and the gap 51g is penetrated through the front end edge 19 side. In other words, the plurality of gaps 51g formed in the arcuate portion 50d and extending in the height direction are formed in the axial direction D across the gap and the entire height direction. The configuration of the arcuate portion 50d other than the above is the same as the arcuate portion 50a (see Fig. 3) of the wrap case 1. Further, the configuration of the strip portion 50b is the same as that of the wrap film cassette 1 (see Figs. 1 to 3). Next, when the stopper 50A formed on the surface of the front plate 12 between the left flap 12fA and the side panel 15A is described, it is compared with the stopper 50 (refer to FIG. 2) formed in the wrap case 1, although the height direction is The distance is the same, but the distance in the axial direction D is longer, extending To the vicinity of the tangent line 12cA.

The size of the first region M1, the second region M2, and the third region M3 in the stopper 50A formed in the main region M between the central region C and the left side plate 15A is the locking region Q (see FIG. 5 (refer to FIG. 5 When the area of B)) is observed, it has the following relationship. The "locking area Q" is a portion surrounded by the outer edge of the stopper 50A (locking mechanism), and the "outer edge of the stopper 50A" can be supplemented even if there is a gap 51g in which the stopper 50A is not partially formed. The gap is 51 g and the whole is regarded as the boundary of the contour of the stopper 50A. In other words, the locking region is a region including the stopper 50A including the portion where the stopper 50A is not present, even if it has a portion (gap 51g) in which the stopper 50A is not present. Hereinafter, the locking region Q of the first region M1 is referred to as a first locking region Q1, the locking region Q of the second region M2 is referred to as a second locking region Q2, and the locking region Q of the third region M3 is referred to. It is called the third locking area Q3. In the prepreg film body 1A during deformation, the area of the first locking region Q1 is formed larger than the second locking region Q2 and larger than the area of the third locking region Q3. In particular, in the example shown in FIG. 5, the area of the first locking region Q1 is twice or more the area of the third locking region Q3.

The height of the stopper 50A in the first region M1, the second region M2, and the third region M3 is the same as that of the stopper 50 (see FIG. 2) of the wrap film holder 1. Further, the stopper 50A is formed in the same manner as the wrap film cassette 1 (see FIG. 2), and is symmetrical with respect to the virtual straight line 12v (see FIG. 2). With respect to the stopper 50A configured as described above, the wrap film 91f can be kept in a state in which it is difficult to slide (easily cut) at the time of cutting, as compared with the stopper 50 (see FIG. 3), thereby improving the pulling of the wrap film 91f. Easy to get out. In addition, in consideration of the balance between the ease of cutting of the wrap film 91f and the easiness of drawing, the area of the second locking region Q2 can be made 70% or less of the area of the first locking region Q1, preferably 1/1. 2 or less, the maximum height HQ2 of the second locking region Q2 is set to be lower than the maximum height HQ1 of the first locking region Q1, and the area of the third locking region Q3 is set to 70 of the area of the first locking region Q. % or less, preferably 1/2 or less, and the maximum height HQ3 of the third locking region Q3 is set to be lower than the maximum height HQ1 of the first locking region Q1.

In the above description, the cutting blade 23 is formed in a V shape along the distal end side 22t, but It can also be formed in a straight line. When the cutting blade is formed in a straight line shape, generally, the wrap film 91f is cut from one end of the width of the wrap film 91f to the other end. In this case, the area of the third region M3 near the end portion is also smaller than the area of the first region M1 close to the central portion C in terms of the area in which the stopper 50 is formed, whereby the plastic wrap can be suppressed from being pulled out. The shear force at the time of 91f is increased, so that the damage of the wrap film 91f can be suppressed.

In the above description, although the left flap 12fA and the right flap 12fB are formed on the front panel 12, the flap 12f may not be formed at all or a flap 12f may not be formed. Even if the flap 12f is not formed, the stopper 50 can be formed at a specific position, and the damage at the time of pulling out the wrap film 91f can be suppressed, and the lateral slip at the time of cutting can be suppressed. However, when the flap 12f is formed, since the distance between the front panel 12 and the cover sheet 22 becomes small when the lid portion 20 is closed, the wrap film 91f is easily attached to the stopper 50, so that the wrap-around prevention effect of the wrap film 91f can be improved. .

In the above description, the gap 51g is formed in the arcuate portion 50a of the stopper 50, but the stopper 50 may be formed in a different manner from the above without forming the gap 51g.

6(A) and 6(B) are views showing a modification of the stopper formed on the wrap film cassette of the embodiment of the present invention, and FIG. 6(C) is a view showing the pattern of the first comparative example. Fig. 6(D) is a view showing the form of the stopper of the second comparative example. The contour of the stopper 55 according to the first modification shown in Fig. 6(A) is substantially the same as that of the stopper 50 (see Fig. 3) (therefore, the area ratio of the first region M1, the second region M2, and the third region M3 is also The difference is that, in a portion corresponding to the strip portion 50b of the stopper 50 shown in Fig. 3, a gap which is divided in the axial direction D is formed to form the stopper 55 in an island shape. The contour of the stopper 56 and the area ratio of the first to third regions M1, M2, and M3 in the second modification shown in Fig. 6(B) are substantially the same as those of the stopper 50 (see Fig. 3), but the difference is different. The gap 57g is formed to extend in the axial direction D.

In the first comparative example shown in Fig. 6(C), no stopper was formed. For ease of comparison, in this aspect, the symbol 58 is referred to as a pattern 58. That is, the pattern 58 is formed on any of the fins 12f without forming a stopper. In the pattern 58 of the first comparative example, when the wrap film 91f is cut at both ends, it is difficult to suppress the lateral sliding of the wrap film 91f which has just been cut. Figure 6 (D) The stopper 59 of the second comparative example is formed over substantially the entire width of the fin 12f, and the area of the first region M1 is not specific to the areas of the other regions M2 and M3. In the stopper 59 of the second comparative example, when the center of the width of the front end of the wrap film 91f is grasped and pulled out, a large shear force is generated on the end portion of the wrap film 91f attached to the stopper 59, and the wrap film is feared. 91f damaged.

[Examples]

The stopper 50 of the embodiment shown in FIG. 3, the stoppers 55 and 56 of the first and second modifications shown in FIGS. 6(A) and 6(B), and FIG. 6(C) are formed. The container of the first comparative example and the stopper 59 of the second comparative example shown in FIG. 6(D) are provided with a wrap film (the shape of each of the stoppers is the same as that shown in FIG. The film case 100 was the same, and was used by 30 evaluators, and the ease of cutting when the wrap film 91f was cut from the center of the width to both ends was evaluated, and the pulling of the wrap film 91f attached to the stopper was pulled. Easy to get out.

In Fig. 7, a graph showing the results of the evaluation is shown. The evaluation can be selected from the following steps: 1: difference, 2: poor, 3: normal, 4: better, 5: good. The vertical axis of Figure 7 is the average of the evaluations of the evaluators, and the horizontal axis is the block. The type of (style). In the graph of Fig. 7, the hatched graph shows the ease of cutting, and the unmarked bar graph indicates the ease of pulling out. The stopper 50 of the embodiment and the stoppers 55 and 56 of the first and second modifications are both easier to cut and easier to pull out than 3.0. Although the pattern 58 of the first comparative example is extremely easy to pull out, the ease of cutting is remarkably low. The stopper 59 of the second comparative example is extremely easy to cut, but the ease of pulling out is remarkably low. Therefore, it is difficult to adopt the pattern 58 of the first comparative example and the stopper 59 of the second comparative example.
