Description

  The present invention relates to a method for producing a film-decorated toilet lid provided to cover a toilet seat attached to a toilet bowl, and a sanitary washing apparatus provided with a toilet lid using this production method.

  Used as an accessory for a seat-type toilet (hereinafter simply abbreviated as “toilet”) or a sanitary washing device, toilet seat device, local washing device, etc. (hereinafter referred to as a sanitary washing device) installed in the toilet. A toilet seat on which a person sits and a toilet lid that covers the toilet seat are provided. These toilet seats and toilet lids can be rotated separately between the standing position and the lying position, or together. Among these, as the toilet lid, generally, a molded body of a resin composition (hereinafter, appropriately referred to as “resin molded body”) is widely used.

  Since the toilet lid covers the toilet seat (and inside the toilet bowl) at the lying position, the user visually observes the surface (outer surface) of the toilet lid at the lying position. Therefore, the toilet lid is required to have at least a good surface appearance (hereinafter referred to as “good appearance”).

  In order to obtain good appearance, there are several means such as painting and kneading of a glittering material, and one of them is a film decoration method. The film decorating method is a technique for coating a toilet lid, which is a resin molded body, with a film decorated with a pattern by printing or the like separately from the molding of the toilet lid.

  As an advantage of the film decoration method, it is possible to decorate the decorative pattern in the state of the film by printing, etc., so it is possible to use a wide variety of patterns and colors rather than painting or kneading the glitter material, etc. It becomes possible to obtain high appearance goodness. Further, by selecting the material of the film, functions such as scratch resistance and prevention of dirt can be added.

  Conventionally, various film decoration techniques have been proposed for obtaining good appearance and functionality of a toilet lid. For example, Patent Document 1 discloses a technique for a toilet accessory including a toilet lid, which can be decorated with a high durability while ensuring smoothness on the surface thereof. Specifically, the toilet seat accessory disclosed in Patent Document 1 is a sheet made by forming a printing layer made of printing ink on the back surface of a base material having transparency on a main body made of a synthetic resin. Is exposed to the surface of the main body and is integrally molded.

  Further, Patent Document 2 discloses a technique for preventing damage caused by contact between an object and a human body during use and maintaining a high appearance and texture of exposed components for a long time in a local cleaning device. ing. Specifically, in the local cleaning device disclosed in Patent Document 2, a film or sheet having a hard layer harder than the member resin surface of the member is provided on the surface of at least one member constituting the local cleaning device. It has a configuration.

  Further, in Patent Document 3, a core material and a covering material are disposed in a decompressable chamber, the inside of the chamber is decompressed, the covering material is softened by heating, and one side of the covering material is pressurized, This is a coating method in which a skin material is brought into close contact with a core material (hereinafter referred to as a “vacuum pressure method”).

  In Patent Document 1 and Patent Document 2, a technique called insert molding is used. This is performed by preliminarily forming a film by vacuum molding or the like, and then setting it in a mold for injection molding. This is a technique for integrating with a molded body, and Patent Document 3 is a technique for coating a film or the like in a separate process from the molding method of the molded body because it is a technique for coating the molded body itself as a core material.

JP 2002-017612 A JP 2002-010952 A JP 2005-262501 A

  In both Patent Documents 1 and 2, a technique is disclosed in which a film or sheet is directly placed inside a mold and injection molding is performed. However, in Patent Document 2, a film or sheet having a high hardness layer is preformed into a shape similar to a part in advance, and the preform molded body is placed in a mold and then molded by injection molding. A technique is disclosed.

  In Patent Document 2, a film or sheet is further preformed. It is not necessary to trim after injection molding to trim unnecessary film or sheet after preforming, but it is possible to prevent the resin from being sneak around by making the end face part undercut, that is, with a burr. The secondary processing of the end face after molding can be reduced.

  However, as a characteristic of toilet lid molding, both the front and back surfaces are noticeable during use, and when a multi-point gate is used, a weld line can be seen. It is molded by injection molding. For this reason, the amount of heat increases, and there is a problem that the printed surface is disturbed near the gate, which impairs the appearance.

  On the other hand, in the vacuum and air pressure method disclosed in Patent Document 3, since the film is coated after injection molding, there is no influence by the amount of heat during molding. However, since the product is covered, a step is inevitably generated on the end face of the film. If the end surface is touched for a long time, the adhesion of the film may be lost and peeling may occur, so in general, the end surface part should be covered with other parts, etc. It is often configured so that it cannot be touched directly. However, the toilet lid is a part that has many opportunities to directly touch the front and back surfaces, and it is difficult to hide only the end surface.

  Also, after coating the covering material, it is necessary to trim the unnecessary portion, but if it is a corner portion of the molded body, it is easy to perform trimming, but if it is a flat portion, the blade hits the molded body, Trimming is difficult. In particular, toilet lids and the like are often made of polypropylene from the viewpoint of chemical resistance to detergents and the like, and are more easily damaged.

  The present invention was made in order to solve such problems, and in the film decoration method using the vacuum / compression method of the toilet lid as a resin molded body provided in a toilet bowl or a sanitary washing device, the appearance is good. An object is to protect the end face and to easily trim unnecessary film without impairing the properties.

  In order to solve the above-described problems, the toilet lid film decorating method according to the present invention is a resin molded body in which the top wall portion and the side wall portion are integrally formed, and has a shape for covering at least the toilet seat. The lid is provided with a step of coating the film from the top wall surface to the side wall surface and the back surface of the side wall by vacuum pressure forming, and a stepped portion formed to protrude from the inner side surface of the side wall. And trimming the film coated on the back surface of the side wall portion from the top to the top.

  According to the above configuration, a step is provided on the inner side of the side wall, and trimming is performed at the step portion, so that trimming can be easily performed without deteriorating appearance even in the case of a film decoration method using a vacuum pressure air method. And the level | step difference of a film end surface is eliminated, the catch by touching with a finger etc. can be reduced, and it can prevent that a film peels.

  In the toilet lid film decorating method, the length from the base of the stepped portion to the top may be longer than the thickness of the film. Thereby, it can be set as the structure where the end surface of a film is not caught by the level | step-difference part.

  In the toilet lid film decoration method, if the toilet lid is formed by injection molding, and the stepped portion is provided in a parting line that is a butt surface between a mold core and a cavity Good. Thereby, trimming can be facilitated without impairing the appearance.

  In the toilet lid, the thermoplastic resin of the base material is not particularly limited, but polypropylene resin (PP), ABS resin (acrylonitrile-butadiene-styrene resin), polystyrene resin (PS), polycarbonate resin (PC), acrylic resin, A polyphenylene ether resin (PPE), a polyethylene terephthalate resin (PET), a fluororesin, etc. are mentioned, but it is not particularly limited. These resins may be used alone or in combination as a polymer alloy. Alternatively, various modification treatments including alloying may be performed, or known resins other than those described above may be combined.

  In the toilet lid, the material of the film to be coated is not particularly limited, but in terms of moldability, polyvinyl chloride (PVC), polyolefin resin, polyester resin (polyethylene terephthalate, polybutylene terephthalate, polyethylene) Naphthalate, polycyclohexyldimethylene terephthalate, etc.) and acrylic resins (polymethyl methacrylate, polyethyl methacrylate, polypropyl methacrylate, polybutyl methacrylate, etc.) are preferred.

  Moreover, in the said toilet lid, although it is the adhesion method of the film which coat | covers a toilet lid, a hot-melt or normal temperature type adhesive agent is preferable. Examples of the material system include acrylic resin, urethane resin, polyester resin, polyamide resin, ethylene butyl alcohol resin, ethylene vinyl acetate copolymer, vinyl chloride / vinyl acetate copolymer, but are not limited. It is preferable to select an optimal combination from the material compatibility with the toilet lid.

  The toilet lid film decorating method according to the present invention can be applied to various fields using the toilet lid, but as a typical example, it can be applied as a toilet lid of a sanitary washing device. That is, the present invention also includes a sanitary washing device including the toilet lid.

  As described above, according to the present invention, in the film decoration method for a toilet lid, which is a resin molded body, trimming is easy without impairing the appearance, and the step on the film end surface is eliminated, and the film is not easily caught. There is an effect that can be done.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference symbols throughout the drawings, and redundant description thereof is omitted.

(Embodiment 1)
[Basic configuration of toilet lid]
First, the basic configuration of the toilet lid according to the present embodiment will be specifically described. As shown in FIG. 1, the toilet lid 54 according to the present embodiment includes a plate-like top wall portion 41 and a side wall portion 42 provided on the outer periphery of the top wall portion 41. Since the toilet lid 54 is used to cover the toilet seat, it has a shape corresponding to at least the toilet seat. In general, since the toilet seat has a substantially semi-elliptical annular structure having a hollow portion connected to the toilet bowl, the shape of the toilet lid 54 (top wall 41) is also substantially semi-elliptical. In FIG. 1, the toilet lid 54 is not illustrated with the back surface facing the upper side in the drawing and the front surface being the lower side in the drawing.

  Here, the toilet lid 54 is attached to the sanitary washing device or the toilet bowl so as to be openable and closable. The state where the toilet lid 54 is in the lying position is the state where the toilet lid 54 is closed and the toilet lid 54 is in the standing position. The state is a state where the toilet lid 54 is fully opened. Therefore, the back surface of the toilet lid 54 refers to a surface that becomes the lower side (that is, the side facing the toilet bowl) when the toilet lid 54 is in a closed state. Further, the front surface of the toilet lid 54 is a surface opposite to the back surface, and refers to a surface that is an upper side when the toilet lid 54 is in a closed state. The rotation of the toilet lid 54 from the lying position to the standing position is referred to as “opening”, and the turning from the standing position to the lying position is referred to as “closing”.

  If the longitudinal direction is defined as the vertical direction and the direction orthogonal to the vertical direction is defined as the horizontal direction, the top wall 41 is defined as one of the longitudinal ends being the leading end 41a and the other being the trailing end 41b. At the same time, the portions on both sides connecting the front end portion 41a and the rear end portion 41b become side portions 41c. The front end portion 41a has a shape (projection shape) in which the outer peripheral shape protrudes in a parabolic shape or an arc shape, and the rear end portion 41b has a shape (flat shape) in which the outer peripheral shape expands in the lateral direction. Since the front end portion 41a and the rear end portion 41b have such shapes, the top wall portion 41 has a substantially semi-elliptical shape as described above.

  As shown in FIG. 1, the side wall portion 42 is continuously provided on the outer periphery of the tip portion 41a and the side portions 41c on both sides, and as shown in FIG. It is a wall-like part that stands up. If attention is paid only to the side wall portion 42, it can be seen as a wall-like “edge” or “frame portion” provided on the entire outer periphery of the top wall portion 41 except for the rear end portion 41b side. it can. The inner surface of the side wall portion 42 is a surface facing the back surface of the top wall portion 41, and the outer surface of the side wall portion 42 is continuous with the surface of the top wall portion 41 to form the entire surface (outer surface) of the toilet lid 54. It is a surface to do.

  Further, as shown in FIG. 2 (b), only the tip 41a is enlarged here, but a step 51 is formed on the parting line (indicated as P / L in the figure) which is the boundary between the core and the cavity in the injection molding. Is provided. The step 51 is also provided on the side wall 42.

With the step 51 as a base point, the angle θ following the line perpendicular to the parting line and the tip portion 41a is close to 90 degrees, and the film does not adhere to the step 51 in the film decoration described later. Since it floats, an appropriate angle is required. If it is too gentle, it becomes thick and the good appearance is impaired, so it is preferably 40 to 80 degrees.

  In addition, a cylindrical or tubular opening / closing shaft 43 is provided on the inner surface of the side wall 42 adjacent to both ends of the rear end 41b. These opening / closing shaft portions 43 are positioned on the inner surface of the side wall portion 42 so as to be coaxial with each other, and the toilet lid 54 is rotatably attached to the sanitary washing device or the toilet bowl. In a state in which the opening / closing shaft 43 is attached to a sanitary washing device or the like, the user grips and raises the vicinity of the tip 41a of the toilet lid 54, for example, so that the opening / closing shaft 43 serves as a rotation shaft and the toilet lid 54 moves between the lying position and the standing position.

  In addition, a leg frame 44 is provided on the back surface of each portion of the top wall portion 41 where the tip portion 41a and the side portion 41c are connected in contact with the inner surface of the side wall portion 42. The leg frame 44 is attached with a leg-like or trapezoidal leg main body (not shown) to constitute a leg of the toilet lid 54. The leg abuts against the surface of the lower toilet seat covered by the toilet lid 54 with the toilet lid 54 closed. As a result, a predetermined interval is formed between the toilet lid 54 and the toilet seat, so that the toilet lid 54 does not sink down excessively in a closed state. Further, if the toilet seat is a “heating toilet seat portion” having a heating function, the back surface of the toilet lid 54 does not directly contact the heating toilet seat portion except for the leg portions, so that the toilet lid 54 is heated by heat from the heating toilet seat portion. Heat dissipation from the heating toilet seat can be suppressed in a state where there is no influence.

  As described above, the toilet lid 54 according to the present embodiment includes the top wall portion 41, the side wall portion 42, the opening / closing shaft portion 43, and the leg portion frame 44. A structural site may be provided. In the present embodiment, since the toilet lid 54 is a molded body (resin molded body) of a resin composition molded by injection molding, the top wall portion 41, the side wall portion 42, the opening / closing shaft portion 43, and the leg portions. Both the frames 44 are integrally formed. For example, the opening / closing shaft 43 or the leg frame 44 is manufactured as a separate body depending on the shape or application of the toilet lid 54, and the top wall 41 or the side wall. 42 may be attached. The same applies to other structural parts.

[Film decoration method]
Next, film decoration on the toilet lid according to the present embodiment will be described. As shown in FIG. 3, the toilet lid 54 is set on the installation jig 62 in the lower chamber box 61, and the film 63 covering the toilet lid 54 is set on the upper surface of the lower chamber box 61. Thereafter, the upper chamber box 64 is lowered to make the upper and lower chamber boxes airtight.

  Then, the inside of the upper and lower chamber boxes is evacuated from the vacuum tank 65 to be in a vacuum state (depressurized state), and the heater 66 is turned on to heat the film 63. Then, as shown in FIG. 4, the installation jig 62 in the lower chamber box 61 is raised, and the toilet lid 54 is brought into contact with the film 63.

  Thereafter, as shown in FIG. 5, by operating the valve of the vacuum pipe 67 to release the vacuum on the upper chamber box 64 side to the atmospheric pressure state, the film 63 is uniformly applied to the toilet lid 54 by the atmosphere. By pressing, the film 63 can be covered along the shape. At this time, the surface of the film 63 that is in contact with the toilet lid 54 has a hot-melt type adhesive, which melts when heated by the heater 66 and presses against the toilet lid 54 so as to adhere.

In addition, as shown in FIG. 5, by putting compressed air from the compressed air tank 68 into the upper chamber box 64, the film 63 can be brought into close contact with the toilet lid 54 with a greater force, as shown in FIG. The film 63 can be wound up to the folded portion of the step 51 as shown. Then, the heater 66 is turned off and cooled, so that the adhesive solidifies and adheres.

  Then, the inside of the lower chamber box 61 is returned to the atmospheric pressure state, and the upper chamber box 64 is raised to take out the covered toilet lid 54.

  Further, the removed toilet lid 54 is trimmed with a cutter or the like at the level difference 51 shown in FIG. 2B, and the unnecessary film 63 is removed. By providing the step 51, the surface of the toilet lid 54 can be trimmed without raising a blade such as a cutter, so that the operation can be easily performed.

  In addition, since the end surface portion is hidden by setting the step 51 to be thicker than the thickness of the film 63, the operation can be performed without touching the end surface portion when opening or closing the toilet lid 54 or cleaning. To prevent peeling from the end face.

[Configuration of Resin Composition]
Next, an example of the configuration of the resin composition used to mold the toilet lid 54 according to the present embodiment will be specifically described.

  The resin composition used in the present embodiment only needs to contain a thermoplastic resin as a resin component. The specific kind of the thermoplastic resin is not particularly limited, and various resin materials widely used in the field of sanitary washing devices including the toilet lid 54 can be suitably used.

  Specific examples of the thermoplastic resin include polypropylene resin (PP), ABS resin (acrylonitrile-butadiene-styrene resin), polystyrene resin (PS), polycarbonate resin (PC), acrylic resin, polyphenylene ether resin ( PPE), polyethylene terephthalate resin (PET), fluororesin and the like can be mentioned but are not particularly limited. These resins may be used alone or in combination as a polymer alloy. Alternatively, various modification treatments including alloying may be performed, or known resins other than those described above may be combined.

  As to which of the thermoplastic resins to select, an appropriate one may be selected in consideration of various conditions such as manufacturing cost, good appearance, and mechanical properties. In general, polypropylene resin is particularly preferably used because of its excellent chemical resistance, good moldability, and low cost.

  The resin composition used in the present embodiment may contain various additives in addition to the thermoplastic resin. Specifically, fillers, plasticizers, internal mold release agents, hydrolysis inhibitors, antioxidants, UV absorbers, antistatic agents, lubricants, flame retardants, foaming agents, inorganic pigments, organic pigments, inorganic antibacterial agents And organic antibacterial agents.

  The manufacturing method of the resin molded body in the present embodiment, that is, the manufacturing method of the toilet lid 54 according to the present embodiment is also not particularly limited, and a molding die (such as a mold) is provided in the internal space that becomes the top wall portion 41. A known molding condition or the like can be applied using an injection molding machine having a known configuration. As an example, if the thermoplastic resin is polypropylene resin and the cylinder diameter φ = 70 mm, the cylinder temperature is in the range of 180 to 220 ° C., the injection pressure is in the range of 60 to 120 MPa, and the injection speed is 20 to 60 mm / s. The conditions within the range can preferably be mentioned.

In addition, an example of the configuration of the film 63 according to the present embodiment will be specifically described.
As a base material of the film 63 used in this embodiment, for example, polyvinyl chloride (P
VC), polyolefin resin, polyester resin (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polycyclohexyldimethylene terephthalate, etc.), acrylic resin (polymethyl methacrylate, polyethyl methacrylate, polypropyl methacrylate, polymethacrylic acid) Butyl etc.) are preferred.

  The film 63 has a printing layer and an adhesive layer in addition to the base material. If a transfer technique is used, a release layer and a carrier sheet are also required. Further, in order to add further functions, a UV coat layer, a fluorine coat layer, or the like may be provided, and a plurality of resins or functional materials may be used in combination. Alternatively, various modification treatments including resin alloying may be performed, or known materials other than those described above may be combined.

  Moreover, although the thickness of the film 63 is arbitrary, 50-500 micrometers is preferable from easiness of shaping | molding (elongation etc.), intensity | strength, etc.

  Next, the present invention will be described more specifically based on the following examples and comparative examples, but the present invention is not limited thereto. Those skilled in the art can make various changes, modifications, and alterations without departing from the scope of the present invention.

Example 1
A polypropylene resin (manufactured by Prime Polymer Co., Ltd., product name: J-882HV) was used as a thermoplastic resin constituting the toilet lid 54, and was molded by injection molding.
The injection molding conditions are as follows. A thermoplastic polypropylene resin composition is prepared by using an injection molding machine having a cylinder diameter φ = 70 mm and melt-kneading the resin composition at a temperature of 200 ° C. in the cylinder of the injection molding machine. Was prepared and injected from the injection port (injection gate) into the mold held at a mold temperature of 50 ° C. The injection pressure at this time was set to 70 MPa, and the injection speed was set to 30 mm / s.

  At this time, a winding portion is formed at an angle of 60 degrees from a line perpendicular to the parting line inside the side wall portion 42 of the toilet lid 54, and a 0.45 mm step 51 is provided where it overlaps the parting line.

  Next, the conditions of film decoration used the double-sided vacuum forming machine (Fuse Vacuum Co., Ltd. NGF-0609).

  As the film 63, a TPO film (polypropylene material, thickness 200 μm, adhesive hot melt) manufactured by Tatsuta Chemical Co., Ltd. was used.

  A jig 62 that matches the shape of the toilet lid 54 is installed on the double-sided vacuum molding machine, and the surface on which the toilet lid 54 molded by injection molding is to be decorated is placed on the jig 62. At this time, the jig 62 was made so that a gap was opened between the lower portion of the side wall portion 42 of the toilet lid 54 and the jig 62. And it sets to a double-sided vacuum forming machine so that a film size may be set to 1000 * 700 mm and it is on the toilet lid 54, and it fixes with a fixing jig.

  Then, the upper chamber box 64 is lowered, the inside of the upper and lower chamber boxes is sealed, and the inside of the upper and lower chamber boxes is depressurized to 2.7 kPa with a vacuum pump. After depressurization, the heater 66 was turned on and heated until the temperature of the film 63 reached about 100 ° C. After reaching the temperature, the atmospheric pressure was released only in the upper chamber box 64 and further pressurized to about 300 kPa with compressed air.

  After the film decorative molding, the inside of the upper and lower chambers was set to atmospheric pressure, and the toilet seat was taken out. As a result, the film 63 was wound up to the inside of the side wall portion 42. Then, trimming was performed with a cutter at the step 51 to remove an unnecessary film, and a toilet lid with excellent appearance was obtained.

  Further, the end face of the film 63 is not caught by the step 51.

(Example 2)
The injection molding conditions and film decoration conditions of the toilet lid 54 are the same. The film 63 is made of Idemitsu Unitech Co., Ltd. polypropylene film (thickness 400 μm, printing layer 15 μm, acrylic adhesive (manufactured by Nichiei Kako) 50 μm) Total: 455 μm ), A toilet lid with excellent appearance was obtained.

  Further, the end face of the film 63 is not caught by the step 51.

(Example 3)
The injection molding conditions and film decoration conditions of the toilet lid 54 are 95 ° C. only for the heating temperature, and other conditions are the same. The film 63 is a PET-G film (thickness 170 μm, printing layer 15 μm, acrylic, manufactured by Riken Technos Co., Ltd.) When the adhesive was made using a system adhesive (manufactured by Etimo) 50 μm total: 455 μm), a toilet lid with excellent appearance was obtained.

  Further, the end face of the film 63 is not caught by the step 51.

(Comparative Example 1)
The injection molding conditions were the same, but no step was provided inside the side wall 42 of the toilet lid 54.

  When film decoration was performed in the same manner as in Example 1, the film 63 was decorated on the surface, but the amount of entrainment at the entrainment portion could vary, and an attempt was made to trim the unnecessary film 63. When trimming without remaining or leaving burrs, the toilet lid 54 was damaged, resulting in poor appearance.

  Moreover, the end surface part of the film is stepped and the nail is caught. Furthermore, when there was a burr, it was caught and peeled off, which was not good.
