  Conventionally, the strength to prevent the bath lid from warping due to the temperature difference between the bathtub and the bathroom relies on the decorative board and the reinforcing material, but the decorative board and the reinforcing material are the front and back surfaces of the core material (face material). Since it is the same size (area), it becomes an obstacle to weight reduction of the bath lid. Further, if reinforcing members are stacked on the front and back surfaces of the core material, the number of manufacturing steps increases.

  The present invention provides a bath lid that is lightweight and is less likely to warp the peripheral edge.

  According to a first aspect of the present invention, there is provided a sheet-like face material comprising a foamed resin having a compression set of 20% or less and having a textured surface or a skin layer formed on a member surface to form a decorative surface; The face material is coated so that the peripheral edge of the face material does not warp by exerting a bending strength larger than that of the face material with respect to the stress that tries to warp the face material. It is a bath lid made of a supporting edge material.

According to 1st invention, a bath lid will be comprised from the face material which consists of foamed resin, and the edge material which coat | covers the circumference | surroundings of a face material, and the same area as the front and back on the front and back of a face material Compared with the structure provided with the hard resin decorative board and the reinforcing member, the weight can be significantly reduced, and the handling property when carrying is improved.
Further, since the face material is made of a foamed resin having a compression set of 20% or less, it does not undergo plastic deformation or breakage with respect to an external force applied to the bath lid during use, but only elastically deforms. For this reason, even if the face material is temporarily deformed by an external force, the face material immediately returns to the original state, and the bath lid does not remain locally depressed or greatly deformed.
When the bathtub opening is covered with a bath lid when hot water is stored in the bathtub, the bath lid can be mounted on the bathtub even if stress is applied to the bath lid due to the temperature difference between the bathtub and the bathroom. Since the edge material supports the face material so that the peripheral edge of the face material placed on the placement surface (upper surface of the bathtub rim) does not warp, the space between the bath lid and the bath lid placement surface of the bathtub It is possible to suppress the gaps generated in the film, and to exhibit a high heat retention ability.

  According to a second aspect of the present invention, in the first aspect, the face material is molded by a foam bead method, and each foam bead is formed on a surface of the face material from which the foam bead pattern is exposed by the foam bead method. The decorative surface is formed by applying a grain having a size smaller than the grain size.

  According to the second aspect, since the size of the embossed surface is made smaller than the particle size of the individual foam beads, the pattern of the foam beads does not stand out from the surface of the face material, and the appearance of the bath lid A sense of quality can be given.

  According to a third invention, in the first or second invention, in the edge member, the length in the direction perpendicular to the peripheral surface of the face material is longer than the length in the same direction as the thickness direction of the front and back surfaces of the face material. Is short.

  According to the third invention, even if the reinforcing member is not provided on the front and back surfaces of the face material over a wide area, the peripheral edge of the face material is simply provided on the peripheral surface of the face material by providing the edge material having a vertically long cross section. Warpage can be suppressed. Moreover, since the rim material becomes thin, the weight can be further reduced.

  According to a fourth invention, in any one of the first to third inventions, the edge member is a strip-shaped stretched resin band attached to a peripheral surface of the face member.

  According to the fourth aspect of the present invention, there is provided a simple structure in which the peripheral surface of the foamed resin is simply covered with a belt-shaped stretched resin band, which is lighter than ever and does not cause warping of the peripheral edge. Can be provided.

  ADVANTAGE OF THE INVENTION According to this invention, the bath lid excellent in the handleability and heat retention property is provided.

The schematic plan view of the bath lid of embodiment. (A) is a schematic perspective view of the bath lid of 1st Embodiment, (b) is AA sectional drawing in Fig.2 (a). (A) is a schematic perspective view of the bath lid of 2nd Embodiment, (b) is BB sectional drawing in Fig.3 (a).

  Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals.

  FIG. 1 is a schematic plan view of a bath lid 1 of the embodiment. A bath lid 1 shown in FIG. 1 represents a bath lid 1A of the first embodiment or a bath lid 1B of the second embodiment, which will be described later.

  The bath lid 1 closes the opening of the bathtub and prevents the heat of the hot water stored in the bathtub from escaping to the outside. In a plan view when viewed from above, the bath lid 1 is formed, for example, in a substantially rectangular shape and is disposed so as to be passed over the upper surface of the rim of the bathtub.

  One or more bath lids 1 block the entire opening of the bathtub. In the example shown in FIG. 1, two bath lids 1 are arranged side by side in the longitudinal direction of the bathtub, and these bath lids 1 cover the entire opening of the bathtub.

(First embodiment)
FIG. 2A is a schematic perspective view of the bath lid 1A of the first embodiment, and FIG. 2B is a cross-sectional view taken along the line AA in FIG.

  The bath lid 1 </ b> A includes a thin plate-like face material 11 and an edge material 14 covering the side surface of the face material 11.

  The face material 11 is formed, for example, in a thin plate shape having a substantially rectangular planar shape, and has a front surface, a back surface on the opposite side, and a side surface (peripheral surface) formed along the outline of the face material 11. In the following description, the front and back surfaces of the face material 11 may be simply referred to as the front surface without being distinguished.

  The face material 11 is made of a foamed resin that is elastically deformed when an external force is applied. The face material 11 is made of, for example, a foamed resin having a compression set of 20% or less calculated by a measurement method defined in JIS K6767. The compression set is a strain that remains in a material when a load is applied to the material and then the load is removed.

Examples of the foamed resin having a compression set of 20% or less include polyolefin resins such as polypropylene, polyethylene, and ethylene vinyl acetate copolymer, flexible urethane foam, and polystyrene-polyolefin composite resin foam. For example, the compression set of polypropylene (EPP) foamed with beads at 30 to 60 magnifications is about 8% to 11%.
On the other hand, examples of the foamed resin having a compression set exceeding 20% include rigid urethane foam, polystyrene-based resin foamed by extrusion foaming or foaming bead method. For example, the compression set of polystyrene (EPS) foamed with beads at 30 to 60 times is about 21% to 24%. When the face material 11 is molded from a foamed resin having a compression set exceeding 20%, the dent generated in the face material 11 does not return to the original, and irregularities occur on the front and back surfaces of the bath lid 1. Not suitable.

  The surface of the face material 11 is, for example, a decorative surface 12 formed by applying a fine pattern (unevenness) to the surface of a mold and transferring the pattern onto a molded product.

  The face material 11 is formed by, for example, a foam bead method. Specifically, gas (for example, hydrocarbon gas) is absorbed into a fine material resin, and the resin is softened at high temperature and foamed by applying pressure.

  The decorative surface 12 is formed by applying a grain having a size smaller than the particle size of each foamed bead to the surface of the face material 11 on which the foamed bead pattern is exposed by molding using the foamed bead method.

  Since the size of the grain is made smaller than the particle size of each foamed bead, the foamed bead pattern is not noticeable from the surface of the face material 11, and the appearance of the bath lid 1A can be given a high-class feeling. In addition, the touch of the surface of the bath lid 1A can be improved, slippage can be prevented, and dirt, fingerprints and scratches can be made inconspicuous. Moreover, the decorative surface 12 has non-water permeability.

  The edge member 14 covers the side surface of the face member 11. The side surface of the face material 11 is covered with the edge material 14 and is not exposed to the outside. Further, the edge member 14 covers a corner portion from the outer edge portion of the decorative surface 12 on the surface of the face member 11 to the side surface of the face member 11.

  The edge member 14 is made of, for example, a polyolefin-based resin such as polypropylene or polyethylene.

  The edge member 14 is provided along the side surface (peripheral surface) of the face material 11 and has a side surface portion 15 that covers the side surface of the face material 11. Further, the edge member 14 has a collar portion 16 that covers the outer edge portion of the decorative surface 12.

  The collar portion 16 is formed so as to protrude from the upper end and the lower end of the side surface portion 15 in a direction parallel to the front and back surfaces of the face material 11.

  The edge material 14 continuously surrounds the peripheral surface of the face material 11, and has a bending strength larger than that of the face material 11 with respect to stress that tends to warp the core material 11 due to a temperature difference between the inside of the bathtub and the bathroom. The face material 11 is supported (reinforced) so that the peripheral edge portion of the face material 11 placed on the bathtub rim is not warped.

  According to the embodiment, the decorative surface 12 is formed on the front and back surfaces of the face material 11 by embossing. Further, an edge member 14 that suppresses warpage of the face member 11 is provided on the peripheral surface of the face member 11.

  For this reason, 1 A of bath lids of embodiment will be comprised from the face material 11 which consists of foamed resin, and the edge material 14 which coat | covers the circumference | surroundings of the face material 11, Compared with a structure in which a hard resin decorative board and a reinforcing member having the same area as the back surface are provided, the weight can be significantly reduced, and the handleability during carrying is improved.

  Further, since the face material 11 is made of a foamed resin having a compression set of 20% or less, it does not undergo plastic deformation or breakage with respect to an external force applied to the bath lid 1A during use, but only elastically deforms. For this reason, even if the face material 11 is temporarily deformed by an external force, it immediately returns to the original state, and the bath lid 1 </ b> A does not remain locally recessed or greatly deformed.

  Even if the bath lid 1A is covered with a bath lid 1A with hot water stored in the bathtub, even if the stress of the bath lid 1A warping in a concave shape due to the temperature difference between the bath and the bath, Since the edge material 14 supports the face material 11 so that the peripheral edge of the face material 11 placed on the lid placement surface (upper surface of the bathtub rim) does not warp, the bath lid 1A and the bath lid of the bathtub A gap generated between the mounting surface and the mounting surface can be suppressed, and a high heat retaining ability can be exhibited.

  In the edge member 14, the length b in the direction perpendicular to the peripheral surface of the face member 11 is shorter than the length a in the same direction as the thickness direction of the front and back surfaces of the face member 11. That is, the width b of the collar portion 16 in the direction parallel to the front and back surfaces of the face material 11 is smaller than the width a of the side surface portion 15 in the direction perpendicular to the peripheral length.

  Even if the reinforcing member is not provided on the front and back surfaces of the face member 11 over a wide area, the peripheral edge of the face member 11 can be prevented from warping only by providing the peripheral member 14 having a vertically long cross section on the peripheral surface of the face member 11. be able to. Moreover, since the edge material 14 becomes thin, it can further reduce in weight.

(Second Embodiment)
Fig.3 (a) is a model perspective view of the bath lid 1B of 2nd Embodiment, FIG.3 (b) is BB sectional drawing in Fig.3 (a).

  The bath lid 1 </ b> B of the second embodiment includes a thin plate-like face material 21 and an edge material 18 that covers the side surface of the face material 21.

  The face material 21 is formed, for example, as a thin plate having a substantially rectangular planar shape, and has a front surface, a back surface on the opposite side, and a side surface (peripheral surface) formed along the outline of the face material 21. In the following description, the front and back surfaces of the face material 21 may be simply represented as the front surface without being distinguished.

  As in the first embodiment, the face material 21 is made of a foamed resin that is elastically deformed when an external force is applied. For example, the face material 21 is made of a foamed resin having a compression set calculated by a measurement method defined by JIS K6767 of 20% or less. .

  Examples of the foamed resin having a compression set of 20% or less include polyolefin resins such as polypropylene, polyethylene, and ethylene vinyl acetate copolymer, flexible urethane foam, and polystyrene-polyolefin composite resin foam.

  In the second embodiment, a skin layer is formed on the surface of the face material 21, and the surface of the skin layer becomes the decorative surface 22. The skin layer is a layer having a high density on the surface of the molded product generated when the foamed resin is molded. That is, the decorative surface 22 (skin layer) has a higher density than a portion (for example, a central portion in the thickness direction) between the front surface and the back surface of the face material 21.

  By forming the skin layer as the decorative surface 22, the foamed bead pattern cannot be seen from the surface of the face material 21, and a high-grade appearance can be given to the appearance of the bath lid 1 </ b> B. Moreover, the decorative surface 22 has non-water permeability.

  The edge member 18 covers the side surface (peripheral surface) of the face member 21. The edge member 18 continuously surrounds the peripheral surface of the face member 21 along the side surface (peripheral surface) of the face member 21. The side surface of the face material 21 is covered with the edge material 18 and is not exposed to the outside.

  The edge member 18 is a strip-shaped stretched resin band made of a polyolefin-based resin such as polypropylene or polyethylene, and is attached to the peripheral surface of the face member 21. The stretched resin band stretches as long as it can be stretched in the longitudinal direction in a certain temperature range, and has a characteristic that it is difficult to stretch in a temperature range during normal use that is lower than that temperature range.

  The edge member 18 is placed on the bathtub rim, exhibiting a bending strength greater than that of the face member 21 with respect to a stress that tends to warp the face member 21 due to a temperature difference between the bathtub and the bathroom. The face member 21 is supported (reinforced) so that the peripheral edge of the face member 21 does not warp.

  According to the second embodiment, the decorative surface 22 is formed on the front and back surfaces of the face material 21 by the skin layer. Further, an edge member 18 that suppresses warpage of the face member 21 is provided on the peripheral surface of the face member 21.

  For this reason, the bath lid 1B of the second embodiment is composed of a face material 21 made of foamed resin and an edge material 18 that covers the periphery of the face material 21, and on the front and back surfaces of the face material 21, Compared with a structure in which a hard resin decorative plate and a reinforcing member having the same area as the front and back surfaces are provided, the weight can be significantly reduced, and the handleability during carrying is improved.

  Further, since the face material 21 is made of a foamed resin having a compression set of 20% or less, it does not undergo plastic deformation or breakage with respect to an external force applied to the bath lid 1B during use, but only elastically deforms. For this reason, even if the face material 21 is temporarily deformed by an external force, it immediately returns to the original state, and the bath lid 1B does not remain recessed or greatly deformed.

  If the bathtub lid is covered with the bath lid 1B while hot water is stored in the bathtub, even if the stress that the bath lid 1B warps in a concave shape due to the temperature difference between the bathtub and the bathroom, Since the edge material 18 supports the face material 21 so that the peripheral edge of the face material 21 placed on the lid placement surface (upper surface of the bathtub rim) does not warp, the bath lid 1B and the bath lid of the bathtub A gap generated between the mounting surface and the mounting surface can be suppressed, and a high heat retaining ability can be exhibited.

  In addition, according to the second embodiment, the bath has a simple configuration in which the peripheral surface of the foamed resin is simply covered with a strip-shaped stretched resin band, and is lighter than ever and does not cause warping of the peripheral edge. A lid 1B can be provided.

  Since the face material 21 is an integral part of the foamed resin, even if the corners of the face material 21 are exposed, the hard corners are not exposed, and a strip-shaped stretched resin band can be used as the edge material 18. That is, even if a reinforcing member is not provided on the front and back surfaces of the face material 21, the warping of the peripheral edge of the face material 21 is suppressed only by providing a belt-shaped resin band as the edge material 18 on the peripheral surface of the face material 21. be able to. Since the reinforcing member that suppresses the warping of the face material 21 is a strip-shaped stretched resin band, the bath lid 1B can be further reduced in weight.

  In addition, you may provide the edge material 18 (stretched resin band) of 2nd Embodiment in the surrounding surface of the face material 11 of 1st Embodiment, and 1st implementation to the surrounding surface of the face material 21 of 2nd Embodiment. The form of edge material 14 may be provided.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
