Description

Technical Field

[0001] This application relates to a reel storage box.

Background Art

[0002] There is a reel storage box in which films such as wraps and foils are wound around a long cylindrical core in a roll shape and stored in a slender rectangular parallelepiped box (see, for example, Patent Documents 1 to 4). Such a reel storage box is required not only to be easy to use, but also to be easy to hold when the user actually picks it up. Conventionally, as one of the methods for improving the ease of holding, a device for improving the grip has been devised. Specifically, this is to perform anti-slip processing or embossing on the surface of the box. Specific examples of the anti-slip processing include coating with an anti-slip agent.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, focusing on the anti-slip processing by coating with an anti-slip agent, there is still room for improving the grip so that the user feels easier to hold while using the same anti-slip agent as before.

[0005] Therefore, the present invention aims to provide a rolled-up material storage box that uses existing anti-slip materials while making it easier for the user to hold. [Means for solving the problem]

[0006] To solve these problems, the inventors focused on the frictional force between the user's fingers or palm and the winding body storage box and conducted various studies. Frictional force consists of static friction and kinetic friction. Static friction is greatest when objects begin to move, and the frictional force decreases after movement (slipping) begins (static friction → kinetic friction). In light of this mechanism, the inventors found that the presence of a new non-slip region (a region with anti-slip processing) during the decay of the frictional force can improve the overall frictional force compared to a case where one surface is a non-slip region.

[0007] Based on these findings, one aspect of the present invention is a winding body storage box capable of accommodating a winding body on which a film is wound, A storage section capable of accommodating a retracted body, including a front plate, bottom plate, rear plate, and side plates, with an open top surface, The opening on the top surface of the housing can be opened and closed, and the lid portion includes a lid plate and a cover piece, It is equipped with, This is a winding material housing box in which a region having a second frictional force higher than the initial frictional force is formed on the surface of the winding material housing box.

[0008] In such a winding material storage box, even if a contact object such as a finger or palm slips in the area with initial friction, the contact object can then come into contact with a new area with second friction, thereby applying a greater frictional force than when it first slipped. Such a structure can be constructed, for example, by coating existing anti-slip materials at regular intervals. Therefore, it is possible to realize a winding material storage box that is easier for the user to hold, while still using such existing anti-slip materials.

[0009] In the above-described coiled material housing box, the ratio of the second frictional force to the initial frictional force may be 1.1 or greater.

[0010] In the above-described winding body housing box, there may be two or more regions where the frictional force is 0.70 N or more.

[0011] In the winding body housing box described above, the region having a second frictional force higher than the initial frictional force may be formed by two or more coating regions, including a first coating region formed by applying a first coating agent and a second coating region formed by applying a second coating agent different from the first coating agent.

[0012] In the above-described winding housing box, different types of varnish may be applied as the first coating agent and the second coating agent.

[0013] In the above-described winding body housing box, a first coating area and a second coating area may be formed on at least one surface of the front plate, bottom plate, rear plate, and lid.

[0014] In the winding body housing box described above, two or more coating regions, including a first coating region and a second coating region, may be arranged along the longitudinal direction of the winding body housing box.

[0015] In the winding body housing box described above, at least a portion of the first coating area and at least a portion of the second coating area may be arranged along the longitudinal direction of the winding body housing box at intervals of 0.3 to 3.0 mm.

[0016] In the winding body housing box described above, the second coating area within the two or more coating areas, including the first coating area and the second coating area, may be arranged such that it occupies a larger proportion than the first coating area when viewed along the short direction perpendicular to the longitudinal direction of the winding body housing box. [Effects of the Invention]

[0017] According to the present invention, it is possible to provide a wound body storage box that uses an existing anti-slip material and allows a user to feel easier to hold.

Figure 2 is a perspective view of the winding body storage device 1 in an open state. Figure 3 is a perspective view showing the winding body storage box 10 and winding body 11 of the winding body storage device 1. In this specification, "upper" and "lower" in the configuration of the winding body storage device 1 and the winding body storage box 10 refer to the orientation shown in Figure 1, that is, the orientation when the bottom plate 31 of the winding body storage box 10 (described later) is at the bottom and the lid plate 40 is at the top. The front plate 30 side of the winding body storage box 10 is referred to as "front," and the rear plate 32 side is referred to as "rear." Furthermore, the longitudinal direction (left-right direction) of the winding body storage box 10 is referred to as "X," the front-back direction perpendicular to the longitudinal direction X of the winding body storage box 10 is referred to as "Y," and the vertical direction of the winding body storage box 10 is referred to as "Z."

[0021] As shown in Figures 1 to 3, the winding body housing device 1 includes a winding body housing box 10 and a winding body 11 on which the film F is wound.

[0022] The winding container box 10 has an overall shape that is, for example, an elongated rectangular parallelepiped. The material constituting the winding container box 10 is, for example, paper such as cardboard, coated cardboard, or corrugated cardboard, but is not limited to this, and other papers and materials known in the industry may be appropriately selected and used. The winding 11 is constructed by winding a film F around a cylindrical core 12.

[0023] Figure 4 is an unfolded view showing the surface of the winding body storage box 10 when it is unfolded. As shown in Figures 3 and 4, the winding body storage box 10 has a storage section 20 that can accommodate the winding body 11 and has an open top surface, and a lid section 21 that opens and closes the opening on the top surface of the storage section 20.

[0024] The storage section 20 includes a front plate 30, a bottom plate 31, a rear plate 32, a front plate side piece 33, a side plate 34, a rear plate side piece 35, a back plate 36, and a back plate side piece 37, etc.

[0025] In the unfolded view shown in Figure 4, the back panel 36, front panel 30, bottom panel 31, and rear panel 32 each have a rectangular shape that is long in the left-right direction X, and are connected to each other in this order in the front-back direction Y. The front panel side pieces 33 are rectangular and are connected to both ends of the front panel 30 in the left-right direction X. The side panels 34 are rectangular and are connected to both ends of the bottom panel 31 in the left-right direction X. The rear panel side pieces 35 are rectangular and are connected to both ends of the rear panel 32 in the left-right direction X.

[0026] The front plate 30 has a wavy cutout 30a formed across both ends in the left-right direction X. The surface of the front plate 30 is provided with a temporary fastening member Q for temporarily securing the end of the film F. The back plate 36 has a cutout 36a formed thereon that connects to the connection line (fold line) between the back plate 36 and the front plate 30.

[0027] As shown in Figure 3, the storage compartment 20 is formed in the shape of a rectangular parallelepiped with an open top. The front plate 30, bottom plate 31, rear plate 32, and side plates 34 constitute the five wall surfaces of the storage compartment 20 other than the top surface. The back plate 36 is folded inward to the front plate 30 and positioned on the back surface of the front plate 30. The part of the front plate 30 above the notch 30a is raised forward, separated from the lower part. The part of the back plate 36 above the notch 36a is raised backward, separated from the lower part. The rear plate side piece 35 is folded inward to the side plate 34 and covers the inner surface of the side plate 34. The front plate side piece 33 and the back plate side piece 37 are folded inward to the inner surface of the side plate 34 and interposed between the rear plate side piece 35 and the side plate 34.

[0028] As shown in the unfolded view of Figure 4, the lid portion 21 includes a lid plate 40, a cover piece 41, a side piece 42 of the lid plate, a side piece 43 of the cover piece, and an opening piece 44, etc.

[0029] The cover plate 40 and the cover piece 41 have a rectangular shape that is elongated in the left-right direction X, and are connected to each other in the front-rear direction Y. The cover plate 40 is connected to the upper end of the rear plate 32, and the cover piece 41 is connected to the front end of the cover plate 40. The cover plate side piece 42 has a rectangular shape and is connected to both ends of the cover plate 40 in the left-right direction X. The cover plate side piece 43 has a rectangular shape and is connected to both ends of the cover piece 41 in the left-right direction X. The opening piece 44 is formed in a strip shape and is detachably connected to the tip of the cover piece 41. A connecting line (cutting line) P1 is formed between the cover piece 41 and the opening piece 44. The cutting line P1 is curved convexly towards the opening piece 44 at its center in the left-right direction X, and both sides are curved convexly towards the cover piece 41. That is, the cutting line P1 is formed in a roughly M shape.

[0030] As shown in Figure 3, the lid plate 40 extends from the upper end of the rear plate 32 toward the front plate 30, and as shown in Figure 1, covers the upper surface of the storage section 20 and closes the opening when the lid section 21 is closed. The cover piece 41 extends from the front end of the lid plate 40 toward the front plate 30. The cover piece 41 is smaller in height than the front plate 30 and is configured to cover the upper area of ​​the front plate 30 when the lid section 21 is closed. As shown in Figure 3, the cover side piece 43 is folded inward from the cover side piece 42 and covers the inner surface of the cover side piece 42.

[0031] Figure 5 is a front view of the winding body storage box 10 with the opening piece 44 cut off. As shown in Figure 5, the tip of the cover piece 41 is provided with a cutting blade 50 for cutting the film F pulled out from the winding body 11 inside the storage section 20.

[0032] The cutting blade 50 is formed, for example, in the shape of a saw blade. The cutting blade 50 has a thin plate shape, such as metal, resin, or vulcanized fiber, and is attached to the back surface of the tip of the cover piece 41. The shape of the cutting blade 50 is conventionally known, such as a straight, V-shaped, or arched shape. The cutting blade 50 may also be positioned on the ridge between the bottom plate 31 and the front plate 30.

[0033] [Embodiments of the present invention] Next, an embodiment of the retractable material storage box 10, which utilizes existing anti-slip materials while being designed to be more user-friendly, will be described below (see Figures 1 to 8).

[0034] The basic structure of the winding material storage box 10 in this embodiment is the same as that of the embodiment described above. However, in this embodiment, a region having a second frictional force higher than the initial frictional force is formed on the surface of the winding material storage box 10, thereby creating a winding material storage box 10 that is easier for the user to hold, even while using existing anti-slip materials (see Figures 1 to 8).

[0035] The surface of the winding material storage box 10 is coated with at least two types of coating agents, thereby forming two or more coated areas. Specifically, the surface refers to the portion including at least one of the surfaces of the front plate 30, bottom plate 31, rear plate 32, and lid portion 21; in other words, the portion that the user's fingers or palm touch when holding the winding material storage box 10. As an example, in the winding material storage box 10 of this embodiment, a coated area 70 is formed, consisting of a first coated area 71 formed by applying a first coating agent and a second coated area 72 formed by applying a second coating agent (see Figure 7).

[0036] For example, a varnish is used as the first coating agent to form the first coating region 71. For example, a different type of varnish is used as the second coating agent to form the second coating region 72. Both the first coating region 71 and the second coating region 72 are stripes of the same width and are formed alternately at predetermined intervals (for example, intervals of 0.3 to 3.0 mm) sequentially along the longitudinal direction X of the winding body housing box 10 (see Figure 7(A)). However, Figure 7(A) shows only one preferred example of a coating region 70 consisting of a first coating region 71 and a second coating region 72. For example, the widths of multiple first coating regions 71 and / or second coating regions 72 are not constant and may vary at a constant ratio or randomly (see Figure 7(B)). The width of the first coating region 71 may be narrower than the width of the second coating region 72 (see Figure 7(C)), or conversely, the width of the first coating region 71 may be wider than the width of the second coating region 72 (see Figure 7(E)). Alternatively, the first coating region 71 and the second coating region 72 may be formed at an inclination with respect to one of the directions defined in the winding body housing box 10 (longitudinal direction X, front-to-back direction Y, up-and-down direction Z) (see Figure 7(D)). Adjacent second coating regions 72 may be partially connected (see Figure 9(B)).

[0037] Furthermore, the first coating region 71 and the second coating region 72 that form the coating region 70 may have the following configurations (see Figure 8). The first coating area 71 and the second coating area 72 may be in the shape of a strip inclined with respect to any of the directions defined in the winding body housing box 10 (longitudinal direction X, front-to-back direction Y, up-and-down direction Z) (see Figure 8(A)). The boundary line between the first coating region 71 and the second coating region 72 may be non-linear, for example, an uneven curve (see Figure 8(B)), or it may be a boundary line that is partially missing (see Figure 9(A)). The orientation of the inclination of the first coating region 71 may be changed alternately to form a V-shape or an M-shape (see Figure 8(C)), or it may be changed randomly instead of alternately. Alternatively, vertical / horizontal lines and inclined lines may be arranged in an N-shape. The first coating region 71 may not only be a single (continuous) strip, but may also be discontinuous and interrupted in the middle (see Figure 8(D)). The first coating region 71 and the second coating region 72 may be arranged unevenly, for example, with one of the multiple first coating regions 71 being missing (see Figure 8(E)). - When considering a straight line extending along the shorter direction perpendicular to the longitudinal direction X of the winding material storage box 10 (the direction in which the dashed line extends in Figure 9) and passing through any part of the second coating area 72, it is desirable that the proportion occupied by the second coating area 72 along that straight line is greater than the proportion occupied by the first coating area 71 (the second coating area 72 occupies more than half) (see Figure 8(D)).

[0038] Furthermore, while the specific magnitudes of the initial friction force in the first coating region 71 and the second friction force in the second coating region 72 are not particularly limited, a suitable value, as an example, would be a second friction force / initial friction force of 1.1 or greater. In addition, two or more regions with a friction force of 0.70 N (approximately 75 gf) or greater may be formed in the coating region 70.

[0039] In this embodiment, an existing varnish, such as a lubricating varnish, is used as the first coating agent to form the first coating region 71, and an existing anti-slip material, such as a non-slip varnish, which forms a surface with greater friction than the aforementioned lubricating varnish, is used as the second coating agent to form the second coating region 72. As a result, in the coating region 70, a region having a second friction force higher than the initial friction force in the first coating region (hereinafter also referred to as the "slippery layer") 71 is formed in the second coating region (hereinafter also referred to as the "non-slippery layer") 72. In such a winding body storage box 10, even if the contact object such as the user's finger or palm starts to slip in the lubricating layer region (first coating region 71) which has an initial friction force, the finger or palm can then come into contact with the non-slippery layer region (second coating region 72) which has a second friction force, making it possible to apply a greater friction force than when it first slipped. Such a structure can be constructed, for example, by coating existing anti-slip materials at regular intervals. Therefore, it is possible to realize a retractable material storage box 10 that is easier for the user to hold, while still using such existing anti-slip materials. Although not specifically shown in the diagram, the coating area may also be composed of a varnish area with irregularities, such as embossed varnish.

[0040] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but the present invention is not limited to these examples. It is clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the ideas described in the claims, and these will naturally also fall within the technical scope of the present invention. For example, the winding body storage box 10 is not limited to that of the above embodiment, and may have other configurations or shapes. The storage section 20 may have at least a front plate, a bottom plate, a rear plate, and side plates, and the lid section 21 may have at least a lid plate and a covering piece. The film F is not limited to food packaging wrap film, but may be aluminum foil, cooking sheet, etc.

[0041] Furthermore, in the above embodiment, an example was given in which two types of coated areas are formed by applying two types of coating agents to the surface of the winding body storage box 10. However, as mentioned above, two or more types of coated areas may be formed on the surface of the winding body storage box 10 by applying at least two types of coating agents. It goes without saying that, although not specifically shown in the figures, three types of coated areas may be formed by applying, for example, three types of coating agents. [Examples]

[0042] The inventors fabricated and tested various coating regions 70 with different morphologies for the smooth layer (first coating region) 71 and the non-smooth layer (second coating region) 72. The details are described below as examples / comparative examples (see Figure 10). In this example, the "sensory evaluation" was conducted by having 100 subjects perform the action of cutting a wrap film F of a commercially available product sold in Japan (manufactured by Asahi Kasei Home Products Co., Ltd., product name: Saran Wrap®) 10 times using the cutting blade 50 of the rolled material storage box 10 (a saw blade similar to the saw blade of the commercially available product described below). The subjects were asked to rate the ease of holding the rolled material storage box 10 during the series of actions on a three-point scale: "easy to hold," "average," and "difficult to hold." In this example, based on the results of this evaluation, the number of "easy to hold" responses was counted, and if there were 50 or more responses, it was marked as "◎," if there were 35 or more responses, it was marked as "〇," if there were 25 or more responses, it was marked as "△," and if there were fewer than 25 responses, it was marked as "×" (see Figure 10). Furthermore, the frictional force detected when the surface of the coated area 70 was traced with a probe is shown graphically in Figure 10. In the graph, the parts indicated by circles or ellipses represent the points where the frictional force reached its maximum value.

[0043] The initial and second frictional forces in each example and comparative example were measured using a Trinity Labs TL201Tt friction measuring instrument. A Trinity Labs finger model, purchased within one year and free from dirt and wear, was used as the tactile contact. A sample piece cut to 30mm x 90mm was fixed to the table surface of the friction measuring instrument. The coated layer side was positioned as the measurement surface. The tactile contact was placed on the surface of the measurement point on the sample piece with a load of 100g and moved 50mm at 50mm / sec to measure the frictional force between the sample and the tactile contact. The maximum load at which the tactile contact began to move was defined as the initial frictional force. If a frictional force higher than the initial frictional force existed, that force was defined as the second frictional force. Measurements were performed in an atmosphere of 23°C and 50%RH. A total of five measurements were taken with different samples, and the arithmetic mean of the five measurements was used as the measured value.

In other words, the packaging container of the example was found to be a packaging container that, when used, for example, as packaging for a winding of plastic wrap, can be used with existing anti-slip materials while still being perceived as easier for users to hold.
