Chopping board sheet and manufacturing method of chopping board sheet

Abstract

To provide a chopping board sheet which has a high effect of antislipping between a chopping board and itself, and a manufacturing method of the chopping board.SOLUTION: An uneven part 40 is formed on a non-laminated surface of a paper layer 10 with a synthetic resin layer 20, and the non-laminated surface serves as a contact surface 10a with the chopping board. As a result, the paper layer 10 makes it easier to absorb moisture and oil contents between the chopping board and the chopping board sheet, than a conventional chopping board sheet where a synthetic resin layer serves as a contact surface, which improves an antislipping effect. Furthermore, an uneven part 40 is formed on the contact surface 10a with the chopping board, the non-smoothness also contributing to improving an effect at antislipping.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a disposable cutting board sheet that is placed on a cutting board. [Background technology]

[0002] Patent Document 1 discloses a cutting board sheet having a structure in which a paper layer is placed at the center with resin layers laminated on the front and back sides. This cutting board sheet has the function of preventing moisture and oil from penetrating the cutting board during cooking, thereby keeping the cutting board clean, and the bottommost resin layer that comes into contact with the cutting board is waterproofed, and the topmost resin layer is antibacterial treated.

[0003] Patent Document 2, like Patent Document 1, discloses a cutting board sheet that has a three-layer structure with a paper layer at the center, a first resin layer on one side and a second resin layer on the other side, and both resin layers have an uneven shape that provides an anti-slip function.

[0004] [Patent Document 1] JP 2000-83844 A [Patent Document 2] JP 2014-73226 A Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, the bottom synthetic resin layer is used as a waterproof layer to prevent moisture and oil generated from the food on the cutting board sheet from adhering to or penetrating the cutting board. However, cutting boards and food are often washed with water before use, and water usually seeps in between the cutting board and the cutting board sheet. In such cases, the cutting board in Patent Document 1 only has a synthetic resin layer in contact with the cutting board, and is slippery when water seeps in between. This may affect the cutting of food.

[0006] In view of this, Patent Document 2 forms a second uneven shape on the second resin layer that comes into contact with the cutting board to suppress slippage between the two. It also describes that a first uneven shape is formed on the topmost first resin layer to suppress slippage of food ingredients and knives. However, depending on the amount of moisture that penetrates between the cutting board and the second resin layer, it may remain within the uneven shape of the resin layer and may not be able to provide a sufficient anti-slip function. In addition, oil may penetrate in addition to moisture, and in this case, it may be difficult to provide a predetermined anti-slip effect only with the uneven shape of the resin layer.

[0007] The present invention has been made in consideration of the above, and has an object to provide a cutting board sheet that has a high anti-slip effect when placed between the cutting board and the sheet, and a method for manufacturing the same. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides A cutting board sheet composed of a laminate of a paper layer and a synthetic resin layer, At least a surface of the paper layer that is not laminated with the synthetic resin layer is formed with an uneven portion, and the non-laminated surface becomes a contact surface with the cutting board. Provide a cutting board sheet.

[0009] The uneven portions may be formed on two surfaces, the non-laminated surface of the paper layer and the non-laminated surface of the synthetic resin layer with respect to the paper layer, and the uneven portions on the two surfaces may be formed in mutually inverted patterns.

[0010] The present invention also provides a method for producing a method for manufacturing a semiconductor device comprising the steps of: A method for producing a cutting board sheet composed of a laminate of a paper layer and a synthetic resin layer, The method includes a processing step of forming an uneven portion at least on a surface of the paper layer that is not laminated with the synthetic resin layer, In the processing step, a roll press machine is used, which includes an upper plate set on a roll and a lower plate disposed opposite to the roll, and in which an inverted processing uneven portion for forming the uneven portion is formed on at least one of the upper plate and the lower plate. The temperature difference between the upper plate and the lower plate is set within a range of ±5 to ±30 degrees, and the laminate is pressed between the upper plate and the lower plate to form the uneven portion. To provide a method for manufacturing a cutting board sheet.

[0011] It is preferable to use an upper plate and a lower plate in which the processing unevenness portion is formed, which is capable of forming unevenness portions with mutually inverted patterns on two surfaces, the non-laminated surface of the paper layer and the non-laminated surface of the synthetic resin layer with respect to the paper layer. Effect of the Invention

[0012] According to the present invention, the paper layer has an uneven surface on the non-laminated surface with the synthetic resin layer, and this non-laminated surface is the contact surface with the cutting board. Therefore, the moisture and oil between the paper layer and the cutting board are more easily absorbed by this paper layer than in the conventional case where the synthetic resin layer is the contact surface, resulting in an improved anti-slip effect. Moreover, the fact that the contact surface with the cutting board has unevenness and is not smooth also contributes to improving the anti-slip effect.

[0013] In addition, by forming an uneven portion on the non-contact surface of the synthetic resin layer that comes into contact with food or a knife, the anti-slip effect between the food or the knife can be improved. In addition, by forming uneven portions with mutually inverted patterns on the two non-laminated surfaces of the paper layer and the synthetic resin layer, multiple cutting board sheets can be stacked and stored, which is convenient and does not take up much space.

[0015] An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the cutting board sheet 1 of this embodiment is composed of a two-layer laminate 30 of a paper layer 10 and a synthetic resin layer 20. As the paper layer 10, various types of paper such as coated paper, wood-free paper, matte paper, and craft paper can be used. Paper having a predetermined basis weight as described in Patent Document 2 and having improved cut-off properties, curl resistance, durability, etc. can also be used. It is also preferable to use absorbent paper that is excellent in absorbing moisture and oil between the cutting board. In this case, from the viewpoint of durability, it is preferable to use absorbent paper for industry, for example, called fruit and vegetable absorbent paper, having a predetermined thickness. The thickness of the paper layer 10 is preferably 0.08 to 0.20 mm.

[0016] The material constituting the synthetic resin layer 20 is not limited, but for example, polyolefin resins such as low density polyethylene, medium density polyethylene, high density polyethylene, etc. can be used as in Patent Document 2. The thickness is preferably 0.02 to 0.20 mm.

[0017] The method for laminating the paper layer 10 and the synthetic resin layer 20 is not limited, and they may be laminated via an adhesive, or, for example, if the resin is a polyolefin-based resin, they can be laminated by applying a melt extrusion method to one surface (lamination surface) of the paper layer 10. This is advantageous in that no adhesive is required.

[0018] The laminate 30 of the paper layer 10 and the synthetic resin layer 20 is provided with an uneven portion 40. In the embodiment shown in Fig. 1, the uneven portion 40 is formed on the contact surface 10a of the paper layer 10, which is the surface (non-laminated surface) opposite to the laminated surface 10b on which the synthetic resin layer 20 is laminated. By forming the uneven portion 40 on the contact surface 10a, a non-slip function is exhibited when placed on a cutting board, compared to when the contact surface 10a is a smooth surface.

[0019] On the other hand, in the embodiment shown in Fig. 2, the contact surface 10a of the paper layer 10 is provided with an uneven portion 41, and the synthetic resin layer 20 also has an uneven portion 42 on the surface 20a (non-laminated surface) opposite the laminated surface 20b on the paper layer 10 side, which is in contact with food or a knife. By providing the uneven portion 42 on the surface 20a, a non-slip function is exhibited when the food or a knife comes into contact with the surface. Therefore, it is preferable that the uneven portions 41, 42 are formed on both the contact surface 10a and the surface 20a, as in this embodiment.

[0020] In addition, as shown in FIG. 2(b), the uneven portion 41 formed on the contact surface 10a and the uneven portion 42 formed on the surface 20a are preferably formed so that the positions of the convex portions 41a, 42a and the concave portions 41b, 42b are inverted relative to each other. That is, it is preferable that the concave portions 42b on the surface 20a correspond to the convex portions 41a on the contact surface 10a, and the convex portions 42a on the surface 20a correspond to the concave portions 41b on the contact surface 10a. As a result, when multiple cutting board sheets 1 are stacked, the convex portions 42a on the surface 20a of one cutting board sheet 1 are inserted into the concave portions 41b on the contact surface 10a of the other cutting board sheet, so that the bulkiness can be suppressed. As a result, when multiple cutting board sheets 1 formed in a sheet shape are stacked in a set, they are conveniently distributed and sold without being bulky. Furthermore, even when multiple cutting board sheets 1 are stacked on top of each other for temporary storage, bulkiness can be suppressed.

[0021] Next, a method for producing the cutting board sheet 1 of this embodiment will be described. First, a laminate 30 is obtained by laminating a synthetic resin layer 20 onto a paper layer 10. The method for laminating and integrating the paper layer 10 and the synthetic resin layer 20 is not limited, and an adhesive can be used as described above, but preferably, the synthetic resin material is melt-extruded onto one side of the paper layer 10 to integrate them.

[0022] Next, the laminate 30 is processed to form the uneven portion 40. Specifically, as shown in FIG. 3, the processing is performed using a roll press machine 100. An upper plate 120 is attached to a roll 110 of the roll press machine 100. A lower plate 130 is disposed opposite the roll 110. The lower plate 130 is provided with an uneven portion 140 for processing formed in an inverted pattern of the uneven portion 40 in order to form the uneven portion 40. The laminate 30 to be processed is transported between the roll 110 and the lower plate 130, and when the roll 110 rotates, the laminate 30 is pressed between the upper plate 120 and the lower plate 130. Since the roll 110 and the upper plate 120 attached thereto have curved surfaces, they are pressed against the laminate 130 in a line contact in the rotation direction, and the inverted shape of the uneven portion 140 for processing of the lower plate 130 is reliably transferred to the laminate 30. By setting the height difference between the convex and concave portions of the processing concave-convex portion 140 of the lower plate 130 to a fixed height, the concave-convex portion 40 is formed only on the contact surface 10a of the paper layer 10 of the laminate 30.

[0023] On the other hand, when forming the uneven portion 41 on the contact surface 10a of the laminate 30 and also forming the uneven portion 42 on the surface 20a, a roll press machine 100 in which the uneven portion for processing is formed on both the upper plate 120 and the lower plate 130 is used as shown in FIG. 4. The uneven portion for processing 142 formed on the upper plate 120 and the uneven portion for processing 141 formed on the lower plate 130 are formed in mutually inverted patterns. Therefore, in the laminate 30 pressed between the upper plate 120 and the lower plate 130, for example, at the position where the protruding portion for processing of the uneven portion for processing 141 of the lower plate 130 contacts the contact surface 10a, a recess is formed on the contact surface 10a and a protruding portion is formed on the surface 20a side at that position, and at the position where the protruding portion for processing of the uneven portion for processing 142 of the upper plate 120 contacts the surface 20a, a recess is formed on the surface 20a and a protruding portion is formed on the contact surface 10a side at that position. As a result, uneven portions 41 and 42 having mutually inverted patterns are formed on the contact surface 10a and the front surface 20a.

[0024] When the laminate 30 is sandwiched by the roll press machine 100 shown in Figs. 3 and 4 to form the uneven portion 40 (or the uneven portions 41, 42), the upper plate 120 and the lower plate 130 are set to have a predetermined temperature difference and processed. The temperature difference between the two is preferably in the range of ±5 to 30 degrees, and more preferably in the range of ±10 to 25 degrees. However, this temperature difference is appropriately adjusted within the above range depending on the material, thickness, etc. of the paper layer 10 and the synthetic resin layer 20. This corrects the distortion of the laminate 30 and suppresses warping of the cutting board sheet 1 on which the uneven portion 40 (or the uneven portions 41, 42) is formed.

[0025] In the above embodiment, the cutting board has a two-layer structure of the paper layer 10 and the synthetic resin layer 20, but as long as the non-laminated surface of the paper layer 10 can be used as the contact surface 10a with the cutting board, a structure in which a paper layer or a synthetic resin layer is further laminated on the synthetic resin layer 20 can be used. This changes the cushioning properties, and can provide different touches for food ingredients and knives.

[0026] In addition, the shape and size of the convex and concave portions of the uneven portion 40 shown in FIG. 1, and the shape and size of each of the convex portions 41a, 42a and each of the concave portions 41b, 42b constituting the uneven portion 41, 42 shown in FIG. 2 are not limited, and can be of various shapes and sizes. For example, the shape can be a lattice shape (see FIG. 2(a)), a ridge shape, a wave shape, etc. The shape and size may be partially different. For example, on the contact surface 10a side that contacts the cutting board, the uneven portions 40, 41 can be made lattice-shaped at the four corners or both sides to enhance the anti-slip effect, and the other parts can be made ridge-shaped or wave-shaped to provide an uneven portion that emphasizes drainage.
