Description

  The present invention relates to a laminated sheet that can be applied in a wide range such as wiping moisture, preventing dirt, removing dirt, waterproofing, keeping warm, and keeping cold. More specifically, towels, bath towels, hand towels, aprons, napkins, slings, waterproof covers, cold protection sheets (heat insulation sheets), heat insulation covers, cold insulation covers, sheets, tablecloths, mats, dusters, cleaners in daily life, labor, and others -It is related with the disposable type laminated sheet suitably used for the sheet | seat for packaging.

  One of the disposable items used in daily life is paper towels. Many of these are made of paper water-absorbing sheets. Specifically, cut sheet paper or cut roll paper sheet is often used. In the case of such a paper towel, it can be used without any problem as long as it wets a wet hand or a wet instrument. However, paper towels have the following disadvantages compared to cloth towels that are commonly used for face washing and shampooing. One of them is the poor tactile sensation due to the strength of paper. The other is poor wiping due to insufficient water absorption. Furthermore, in the case of paper towels, the towels tend to be damaged due to insufficient strength.

  The water absorbent sheets disclosed in the following Patent Documents 1 to 4 can solve the above-described problems. This is because the water absorption sheet has a laminated structure, so that the amount of moisture absorption and strength are large. Of course, in the case of these conventional products, it is possible to ensure good usability by adopting a flexible and tactile material as the surface layer and the back layer.

The water-absorbing sheets disclosed in Patent Documents 1 to 4 are desirable in terms of improving tactile sensation, water absorption, strength, and the like. However, when improving usability according to various usage modes, new ingenuity and ingenuity are required for the problems pointed out in (01) to (06) below.
(01) The laminated structure increases the thickness of the water absorbing sheet. Therefore, it is not easy to apply a water absorbing sheet to a required surface or to maintain the state.
(02) As a countermeasure described above, forming an adhesive portion (adhesive layer) or attaching a string to the water absorbent sheet has been implemented, but even with these means, the water absorbent sheet cannot be maintained in a desired state. Sometimes.
(03) Thick water-absorbing sheet is not easy to stably hold the folded state unless some measures are taken, and it is bent and held in a sharp shape like a triangle to remove dirt on the corners, etc. It is also difficult to do.
(04) When the amount of moisture adhering is large, the waterproof function and the cover function are impaired by the adhering water overflowing from the sheet surface.
(05) The above-described patent document technique is not conscious of such a problem, and does not disclose means for solving it. Therefore, this type of sheet product requires a new technology for solving such a problem.
(06) When solving the above problems, it is desirable to satisfy as many requirements as possible, including enhancement of functions, but when many requirements are imposed on products that are only sheet-like structures, While technical difficulty increases, some of the desired effects are missing.

  In view of such technical problems, the present invention intends to provide a laminated sheet that can satisfy functions enhancement, safety, simple configuration, ease of production, low cost, disposal property, and the like.

(11) The laminated sheet according to the present invention is characterized by the following technical contents as a first problem solving means for achieving the intended purpose. That is, the laminated sheet as the first problem solving means includes a top sheet layer for forming the top surface side, a back sheet layer for forming the back surface side, and an elongated deformable shape holding member, And the surface material which the surface sheet layer consists of a planar material which has water absorption and / or water permeability, and a back surface sheet layer has any one physical property chosen from water absorption, water permeability, and waterproofness Alternatively, it is made of a sheet material having water absorption and water permeability, and the shape holding member is made of a deformable linear material, and the top sheet layer and the back sheet layer are at least part of the edge. The condition that the adhesive portion for embedding the member is formed is satisfied by being laminated and integrated, and the shape holding member is embedded and held along the length direction of the adhesive portion for embedding the member. And wherein the are.
(12) The laminated sheet according to the present invention is characterized by the following technical contents as a second problem solving means for achieving the intended purpose. That is, the laminated sheet as the second problem solving means is the one described in (11) above, wherein an internal intervening layer having water absorption and / or heat insulating properties is interposed between the top sheet layer and the back sheet layer. It is characterized by being.
(13) The laminated sheet according to the present invention is characterized by the following technical contents as a third problem solving means for achieving the intended purpose. That is, the laminated sheet as the third problem solving means is characterized in that, in the above described (11) or (12), a ridge portion is formed at the edge portion so as to protrude toward the surface sheet layer side. And
(14) The laminated sheet according to the present invention is characterized by the following technical contents as a fourth problem solving means for achieving the intended purpose. That is, in the laminated sheet as the fourth problem solving means described in any one of (11) to (14) above, a notch for removing the shape maintaining member is formed in the adhesive portion for embedding the member. It is characterized by.

The laminated sheet according to the present invention has the following effects.
(21) Since the laminated sheet is a laminated sheet with a sheet layer for the front and back surfaces with the specified physical properties, it is used for wiping moisture, for preventing dirt, for removing dirt, for waterproofing, for heat insulation, Towels, bath towels, hand towels, aprons, napkins, slings, waterproof covers, cold protection sheets (heat insulation sheets), heat insulation covers, cold insulation covers, sheets, table cloths, etc. It is versatile, such as mats, dusters, cleaners, and packaging sheets, and it is only necessary to stack low-priced materials.
(22) The deformable shape holding member embedded and held in the bonding portion between the top sheet layer and the back sheet layer is at least a part of the edge of both layers and is along the length direction of the bonding portion. In addition, the shape after deformation is self-held. As an example, when the shape holding member is deformed as the laminated sheet is folded, the shape holding member holds the sheet folded state depending on its deformed shape. The shape when the laminated sheet is attached to the body or attached to the container is also held by the shape holding member that deforms accordingly. Further, when a part of the laminated sheet is bent into a sharp shape such as a triangle by using the embedded portion of the shape holding member, the shape holding member holds the bent shape. This means that when the laminated sheet is deformed in accordance with each use purpose or use condition, it is held by the shape holding member. Therefore, the convenience when using the seat is remarkably improved and functionally enhanced.
(23) Since the shape-retaining member is a deformable linear material and deforms with a small force, it is impossible for a normal case to damage a person or an object. In addition, since the shape holding member is in the adhesive portion between the top sheet layer and the back sheet layer and is completely encapsulated, there is no danger that it can be said that the shape retaining member is totally visible. Therefore, the safety in use and handling of the laminated sheet is sufficiently ensured.
(24) The adhesive portion where the shape-retaining member is embedded is on the edge of the sheet that has almost no influence upon wiping or other use. Therefore, the use is hardly hindered by the shape maintaining member.
(25) Since the top sheet layer and the back sheet layer are simply laminated and integrated, and the shape maintaining member is only embedded and held in the adhesive portion, the sheet configuration is simple. Easy to manufacture. What is particularly effective is that the shape holding member is held by using an adhesive portion between the top sheet layer and the back sheet layer. In such a dual-use configuration, there is no need for a separate means for holding the shape holding member, so that the simplification of the configuration and the ease of manufacture become more remarkable.
(26) Since the material is inexpensive and the structure is simple and easy to manufacture, the cost of the laminated sheet can be reduced as a whole.
(27) In the case of a laminated sheet in which an internal intervening layer having water absorption and / or heat insulation (heat retention / cold insulation) is interposed between the top sheet layer and the back sheet layer, it depends on the internal intervening layer Thus, water absorption and / or heat insulation can be improved.
(28) In the case of a laminated sheet in which a jetty portion that protrudes toward the surface sheet layer side is formed at the edge portion, the jetty portion can prevent water adhering to overflow from the sheet surface to the outside of the sheet. As a result, the waterproof function and the cover function are further enhanced.
(29) In the case of a laminated sheet in which a notch for removing the shape holding member is formed in the adhesive portion for embedding the member, it is desirable for disposal. That is, at the time of disposal of the used laminated sheet, it is possible to improve the disposal property of the laminated sheet by separating the shape holding member from other parts using a notch and separating them. In particular, when the shape-retaining member is made of a material that can be recycled or reused, such a process can also lead to the collection of resource garbage.

  About each embodiment of the lamination sheet which concerns on this invention, embodiment of FIGS. 1-2 is described first.

  In the laminated sheet 11 illustrated in FIG. 1 to FIG. 2, 21 is a surface sheet layer for forming the surface portion side, 31 is a back surface sheet layer for forming the back surface portion side, and 41 is the surface sheet layer 21 and the back surface. An internal intervening layer 51 interposed between the sheet layer 31 and the shape-retaining member which is elongated and deformable is shown.

  The top sheet layer 21 is made of a planar material having either or both of water absorption and water permeability. Speaking of the planar material in this case, it is a planar fiber assembly, which is in the form of a sheet layer. As is well known, the water absorption here refers to a phenomenon in which when water is immersed in water, moisture adheres to the inside and the air occupying the inter-fiber space is replaced with water. Water permeability in response to this refers to a phenomenon in which, for example, when water is placed on the upper surface of a fiber assembly held in a horizontal state, the water passes through the interfiber space and below the fiber assembly. The surface sheet layer 21 made of a hydrophilic sheet material (fiber assembly) often has both water absorption and water permeability, and the surface sheet layer 21 made of a hydrophobic sheet material (fiber assembly). Are mostly water-permeable. Specific examples of the surface sheet layer 21 include paper (including recycled paper and synthetic paper), cloth (including those made of natural fibers and synthetic fibers), and non-woven fabric (made of natural fibers / chemical fibers) (Including those made of mixed fibers). Furthermore, the fibers forming the planar material (fiber assembly) are hydrophilic, such as natural fibers such as cotton, regenerated fibers such as rayon, other synthetic fibers subjected to hydrophilic processing, water absorption Polymers and the like can be used, and examples of hydrophobic materials include polyester fibers, acrylic fibers, polyimide (nylon) fibers, and the like. About the surface sheet layer 21 which consists of such a raw material, the same type or different planar material may be laminated | stacked two or more. When the surface sheet layer 21 is in direct contact with the surface of the body (skin or the like), a soft and tactile material is adopted.

  The back sheet layer 31 is made of a planar material having any one physical property selected from water absorption, water permeability, and waterproof properties, or a sheet material having water absorption and water permeability. Therefore, the back sheet layer 31 has only water absorption, only water permeability, only waterproof, or has water absorption and water permeability. The water absorption and water permeability here are the same as above. The waterproof property refers to a phenomenon in which water does not pass from one surface (one surface) to the other surface (one surface) of the back sheet layer 31. When the back sheet layer 31 has water absorption or water permeability, it is made of the same planar material (fiber assembly) as described above. On the other hand, the waterproof back surface sheet layer 31 is made of a plastic non-porous sheet material as a representative example. Even if the back sheet layer 31 is a perforated sheet material such as knitted fabric or woven fabric, it is effective as the waterproof back sheet layer 31 as long as the hole is extremely small and does not allow water to pass under atmospheric pressure. It is. Examples of the other back sheet layer 31 include a laminated paper in which paper and a plastic film are bonded together, and a composite sheet in which any one of a knitted fabric, a woven fabric, and a nonwoven fabric and a plastic film are bonded together. The back sheet layer 31 that is relatively bonded to the top sheet layer 21 or is partially bonded to the top sheet layer 21 is preferably made of a plastic material that can be heat sealed or hot melted. It is desirable to adhere to one side or both sides of the substrate. Further, the back sheet layer 31 is also flexible and has a good tactile feel in a typical embodiment.

  As is obvious, the internal intervening layer 41 is also layered to have a sheet layer shape. The inner intervening layer 41 may be any of a single body or a composite of the knitted fabric, the woven fabric, and the non-woven fabric. In a typical example, the inner intervening layer 41 is composed mainly of pulp. In one example, only the pulp is stratified. In another example, the pulp is covered with one or more of a knitted fabric, a woven fabric, and a non-woven fabric to be layered. In any of these examples, the internal intervening layer 41 may have water absorbability and also water retention. Similarly, when the internal intervening layer 41 is made of a single body or a composite of the knitted fabric, the woven fabric, and the non-woven fabric, the inner intervening layer 41 also has water absorption, and in some cases has water retention.

  The shape holding member 51 is made of a deformable linear material. A typical example of the shape holding member 51 is a metal wire that can be easily bent. In terms of material, the holding member 51 is made of copper or iron. The holding member 51 is generally circular in cross section, but may be a polygon having a cross section (e.g., a flat quadrangle) or an irregular cross section. The holding member 51 may be made of a metal stranded wire, and the holding member 51 may be covered with a plastic sheath. When the shape holding member 51 is bent and deformed by applying a force to the shape holding member 51, the shape holding member 51 self-holds the bent shape by the plastic deformation. Therefore, the bent shape of the shape holding member 51 is held unless a new force is applied.

  The laminated sheet 11 having a rectangular shape illustrated in FIGS. 1 to 2 is formed by laminating an inner intervening layer 41 between a front surface sheet layer 21 and a rear surface sheet layer 31 each having a rectangular shape. It is. Therefore, the top sheet layer 21 and the back sheet layer 31 overlap each other at each edge 12 which is the four sides of the laminated sheet 11. In this case, a part of these edges 12, that is, one side of the laminated sheet 11 is set as an adhesive portion 13 for embedding a member, and a shape holding member 51 is provided along the length direction of the adhesive portion 13 inside thereof. Intervened. In the laminated sheet 11, the top sheet layer 21 and the back sheet layer 31 are bonded to each edge 12 including the bonding portion 13 (a part of the edge 12). As an example, when the back sheet layer 31 can be heat-sealed or hot-melted, the bonding portions 13 and the other edges 12 of the both sheet layers 21 and 31 are relatively bonded by the heat bonding means. In another example, an adhesive is applied to the inner surface of each edge 12 including the bonding portion 13 so that they are relatively bonded. Thus, when the entire peripheral portion of the laminated sheet 11 is sealed, the inner intervening layer 41 is sealed between the two sheet layers 21 and 31, and the shape maintaining member 51 is embedded and held in the adhesive portion 13. In the laminated sheet 11, a jetty portion 14 that protrudes toward the surface sheet layer 11 is further formed at the edge 12. Specifically, each edge 12 (including the bonding portion 13) is folded and bonded to the surface sheet layer 11 side, whereby the jetty portion 14 is formed. Bonding in this case is also performed by the same heat bonding means as described above or by an adhesive bonding means. It is desirable in terms of recycling and reuse that the shape holding member 51 is separated and collected from the laminated sheet 11 when the used laminated sheet 11 is discarded. Therefore, in the laminated sheet 11, it is easy to cut the predetermined portion of the laminated sheet 11 to separate the shape holding member 51, that is, to cut the adhesive portion 13 (edge 12) where the shape holding member 51 is interposed. Therefore, a notch 15 for sheet tearing is formed at the end of the adhesive portion 13 in FIG.

  In addition, one or a plurality of strings 61 are attached to the top sheet layer 21 and / or the back sheet layer 31 of the laminated sheet 11 as necessary, or a single or a plurality of objective adhesive layers 62 are provided as necessary. Or As a specific example, in the embodiment of FIGS. 1 to 2, a plurality of cords 61 are attached in the vicinity of the edge 12 of the back sheet layer 31 as shown in FIG. 1, and a plurality of spot-like objective adhesive layers 62 are provided. As shown in FIG. 2, the back surface sheet layer 31 is provided in a scattered manner. In this case, a release paper 63 that is peeled off during use is attached to the adhesive surface of each objective adhesive layer 62.

The laminated sheet 11 illustrated in FIGS. 1 and 2 also includes the following embodiments (31) to (37).
(31) Any one or more of the top sheet layer 21, the back sheet layer 31, and the internal intervening layer 41 is added more than in the example of FIGS.
(32) The internal intervening layer 41 is omitted from the laminated sheet 11 of FIGS.
(33) In the laminated sheet 11 of FIGS. 1 and 2, the internal intervening layer 41 is omitted, and the top sheet layer 21 and / or the back sheet layer 31 are increased from the example of FIGS.
(34) In the laminated sheet 11 shown in FIGS. 1 and 2, the shape holding member 51 is embedded and held in the two parallel edges 12, or the shape holding member 51 is embedded in the two edges 12 perpendicular to each other. The shape holding member 51 is embedded and held in the edges 12 of the three sides, or the shape holding member 51 is embedded and held in the entire peripheral edge.
(35) In the laminated sheet 11 of FIGS. 1 to 2, the jetty portion 14 on the surface sheet layer 21 side is not formed on the entire peripheral edge 12 but only on a part of the edge 12. Specifically, a jetty portion 14 is formed along two parallel edges 12, a jetty portion 14 is formed along two perpendicular edges 12, or a jetty along three edges 12. Part 14 is formed.
(36) In the laminated sheet 11 of FIGS. 1 and 2, the string 61 may be attached to either side of the back sheet layer 31 and / or the top sheet layer 21. In this case, the number of the strings 61 may be singular or plural. Therefore, the back surface sheet layer 31 may be attached with more strings 61 than the illustrated example. Specifically, it is attached to each edge 12 by one address or a plurality of addresses. The string 61 may also be attached to the top sheet layer 21 in addition to the back sheet layer 31, or may be attached to the top sheet layer 21 instead of the back sheet layer 31. Further, all the cords 61 of the laminated sheet 11 may be omitted.
(37) In the laminated sheet 11 of FIGS. 1 to 2, many or a plurality of objective adhesive layers 62 are also provided on the top sheet layer 21, or only the top sheet layer 21 instead of the back sheet layer 31. Provided. All the objective adhesive layers 62 of the laminated sheet 11 may be omitted.

  Next, the embodiment of FIG. 3 will be described for each embodiment of the laminated sheet according to the present invention.

  The laminated sheet 11 in FIG. 3A has a triangular outer shape, the laminated sheet 11 in FIG. 3B has a square outer shape, the laminated sheet 11 in FIG. 3C has a trapezoidal outer shape (isosceles trapezoidal), and FIG. The laminated sheet 11 of D) has a pentagonal outer shape. The outer shape of the laminated sheet 11 in FIG. 3E is a perfect circle, the outer shape of the laminated sheet 11 in FIG. 3F is an ellipse, and the outer shape of the laminated sheet 11 in FIG. Further, the laminated sheet 11 in FIG. 3H has a cross-shaped outer shape and a semicircular recess in a part thereof. In this case, the dent may be V-shaped, U-shaped, or polygonal (eg, square). When these laminated sheets 11 are grouped into shapes having similar external shapes, (A) to (D) in FIG. 3 are polygon groups, (E) to (G) in FIG. 3 are circular groups, and FIG. ) Is a variant group that does not belong to the above two groups. The deformed group includes an hourglass shape and a spindle shape not shown. A concave portion such as a semicircular shape, a V shape, a U shape, or a polygon shape may be provided on the laminated sheet 11 already described or an arbitrary side (edge 12) of the laminated sheet 11 described here. All the matters described in the embodiment of FIGS. 1 to 2 are technical for each laminated sheet 11 described here, including the illustrated examples of FIGS. Everything can be implemented within the scope of compatibility.

  About the laminated sheet 11 having the outer shape exemplified in FIGS. 1 to 2 and FIG. 3 (B), a laminated sheet can be obtained by making a roll-like long product with a cut (for example, perforation) for each sheet. 11 can be cut out and used for each unit (one product).

  When the laminated sheet 11 of FIGS. 1 to 2 (those without the cord 61 or the objective adhesive layer 62) is used as a “hair towel”, it is as follows with reference to FIG. Initially, as shown in FIG. 4 (A), the laminated sheet 11 with the edge 12 with the shape maintaining member 51 facing upward is wound around the neck and the portion below it. At this time, the edge 12 including the shape holding member 51 is loosely wound around the neck to form a loop shape. This loop shape is held by a shape holding member 51 that holds the deformed shape. 4A, both end portions 12a and 12b of the upper edge 12 are hooked on the inner and outer sides of the overlapping edge 12, and the hooks including the shape retaining member 51 are hooked. The part is twisted. Since the shape holding member 51 is twisted and deformed by this twist and has a clamping function, the laminated sheet 11 is held at a predetermined part of the body without being unwound. After this, the lower edge 12 is gripped, and the gripped laminated sheet 11 is pulled up while being turned upside down. By doing so, the laminated sheet 11 has a cylindrical shape surrounding the hair, and the edge 12 including the shape holding member 51 follows the hairline. The reason why the laminated sheet 11 becomes like this is that it is handled as such. The wet hair is wiped with the laminated sheet 11 in this cylindrical shape. Next, in order to cover the hair with the cylindrical laminated sheet 11, this is folded at the top of the head or the frontal area, and the final folded piece is bundled on the frontal side, and then a part of the edge 12 including the shape holding member 51. As shown in FIG. 4 (B), it is wound like a vine from the frontal side to the parietal side. Thus, the laminated sheet 11 covered with the hair is tightened and fits the hair. Furthermore, since the shape holding member 51 deformed into a vine shape self-holds the deformed shape, the hair covering state by the laminated sheet 11 is held as it is.

  FIG. 5 shows two other usage examples of the laminated sheet 11. Of these two examples, in the case of FIG. 5A in which the laminated sheet 11 is used as a napkin during a meal, the laminated sheet 11 is hung on the chest and abdomen. Specifically, in accordance with the description of FIG. 4A, the laminated sheet 11 with the edge 12 having the shape holding member 51 on the upper side is wound around the neck and the portion below it. In this case, both ends of the upper edge 12 may be caught or twisted as in the previous example. However, it is considered that both end portions of the laminated sheet 11 overlap on the back side. In addition, the pair of cords 61 are tied on the back side, or the back sheet layer 31 of the laminated sheet 11 is spot-stopped (adhered) to the chest and abdomen clothing through the objective adhesive layer 62. In the usage example of FIG. 5, the laminated sheet 11 prevents the clothes from becoming dirty due to spillage during meals or the like. What is desirable in this case is the function of the jetty 14 for liquid spillage. When the amount of spilled liquid is large (one spilled amount) and it flows down through the surface sheet layer 21, the jetty portion 14 causes the spilled liquid to leak out of the laminated sheet 11. Because it dams up. The spilled liquid that has been dammed will immediately penetrate into the laminated sheet 11 and be absorbed.

  FIG. 5B shows an example in which the laminated sheet 11 having a larger size than that in FIG. Furthermore, it is used as an apron for the upper body. Similarly to the previous example, in this usage example, the laminated sheet 11 is attached to a predetermined part of the body via the edge 12 having the shape holding member 51, the string 61, the objective adhesive layer 62, and the like. When the laminated sheet 11 is used as an apron for the lower body, it may be worn so as to be wound around the lower body. If it is the laminated sheet 11 with a large size, it will become an apron which can cover from the front surface of the upper body to the front surface of the lower body. When the laminated sheet 11 is worn as a jacket-type cold protection sheet (heat insulation sheet), it may be as shown in FIG. The wearing mode of the laminated sheet 11 in that case may be reversed in front and back in comparison with FIG.

  FIG. 6 shows three usage examples of the laminated sheet 11 other than those described above. Among these three examples, in the case of FIG. 6 (A) in which the laminated sheet 11 is used as a neck warmer (a heat insulation sheet from the neck circumference to the shoulder tip) when sleeping on a futon, the laminated sheet 11 is formed so as to cover a predetermined portion. It is hung. When the upper futon or the like is hung from above, the laminated sheet 11 prevents the intrusion of the gap air from the neck and shoulders, so that those portions can be kept warm. Also in this case, the effect of cold prevention and heat insulation is further enhanced by fitting the upper side of the laminated sheet 11 to the neck circumference, the shoulder tip and the like while deforming the edge 12 having the shape holding member 51.

  In FIG. 6 (B), the laminated sheet 11 is folded to a convenient size in order to use it as a wiping type cleaning tool (such as a duster cleaner). In this example, the shape holding member 51 embedded and held in the adhesive portion 13 of the edge 12 is folded into a U shape and held in shape as the laminated sheet 11 is folded. The laminated sheet 11 is held in a folded state by the shape holding member 51 in this state. In addition, the shape holding member 51 can easily maintain the spread state of the surface of the laminated sheet 11 in the folded state.

  In FIG. 6C, the laminated sheet 11 is folded into a convenient shape in order to use it as a wiping type cleaning tool. That is, since the laminated sheet 11 in this example forms a sharp shape like a triangle at the edge 12 including the shape holding member 51, the laminated sheet 11 is folded about three times. The sharpened portion of the laminated sheet 11 formed in this way is convenient for removing dirt such as a corner portion and a narrow portion. Can wipe strongly and firmly.

  The laminated sheet 11 can be further described as follows: based on the above-described contents, a laminated structure with an appropriate number of layers, an appropriate surface area, an appropriate material, etc. Desired products such as waterproof covers, heat insulation covers, cold insulation covers, sheets, table cloths, mats, dusters, cleaners, and packaging sheets can also be obtained. These are used in a well-known manner such as “apply”, “cover”, “wrap”, “lay”, “wipe”, “wrap” to a person or an object. The laminated sheet 11 for such use is also used by utilizing the shape holding function because the adhesive portion 13 for embedding the member is formed in a part of the edge 12 and the shape holding member 51 is embedded therein. It is possible to improve convenience in handling or handling.

  The laminated sheet 11 is discarded every time it is used. Usually, it is thrown away after each use. In that case, it is preferable that the edge 12 containing the shape holding member 51 is cut and the shape holding member 51 is taken out therefrom. The reason is that while the disposal property of the laminated sheet 11 is enhanced, the shape holding member 51 can be utilized for recycling and reuse. In order to facilitate this take-out operation, a notch 15 for sheet tearing is formed at the end of the bonding portion 13 (edge 12). Therefore, when the shape holding member 51 is taken out, the adhesive portion 13 (edge 12) may be cut through the notch 15.

  The laminated sheet according to the present invention has a wide range of uses such as being applicable in daily life, labor, and others, and it has enhanced functions, safety, simple structure, ease of production, low cost, disposal A product that satisfies the processability can be provided. Therefore, it can be said that the industrial applicability is high.
