  The present invention relates to a method for producing a labeled shaped article, and a labeled shaped article.

  2. Description of the Related Art Conventionally, a molded body with a display unit in which a product name, a manufacturer name, a logo mark, a pattern, a product description, and the like are provided on the surface of a molded body such as various containers, covers, and trays is known. As a method of providing a display part on the surface of a molded object, the long film on which the display part is printed is laminated on the surface of a molding precursor (long sheet before molding) such as a resin sheet, and then the laminated molding A method of forming and processing a precursor into a container shape or the like by sheet forming or the like is widely used (see, for example, Patent Document 1). In this method, generally, a long film on which display portions are printed at a predetermined pitch is laminated on the entire surface of a resin sheet.

  By the way, it is not easy to provide a specific pattern etc. in the predetermined position of a molded object using the long film by which the display part was printed. For example, the film is stretched by the tension applied when the long film is fed out, and as a result, the printing pitch is stretched and the display portion is displaced. Moreover, since the method of laminating a long film generally laminates a film on the whole surface of a forming precursor, not only facilities become large-scaled, but the film of the part (surplus part) which is not processed is wasted, There is room for improvement also from the viewpoint of material cost reduction and the like.

  In some cases, a label provided with a display portion is affixed to the surface of a molded body that has been molded into a container shape, etc. In this case, the display label is made clean along the curved surface of the molded body, particularly a three-dimensional curved surface. It is difficult to stick to

  A method for manufacturing a labeled molded body according to the present invention is a method for manufacturing a labeled molded body to which a display label is affixed, and selectively affixes the display label in a range including a molded part of a molding precursor. It is characterized by including a first step and a second step of forming and processing the portion to be molded to which the display label is attached.

  As described above, there is a demand for a molded product with a display unit, which is excellent in design, without positional deviation of the display unit. The present inventors have intensively studied to solve this problem, and as a result, the display label is selectively attached in the range including the forming part of the forming precursor, and the forming precursor to which the label is attached is shaped like a container Found a method of forming processing. By using such a method, it is possible to accurately provide a specific pattern or the like at a predetermined position of the molded body, and also display a three-dimensional curved surface of the molded body, which has been difficult to apply a label cleanly. It becomes possible to stick the label neatly.

  The labeled molded body according to the present invention includes a molded body having a three-dimensional curved surface formed by molding a resin sheet, and a display label partially attached to the molded body, wherein the display label is the resin The sheet is formed together with the display label to-be-applied portion of the manufactured sheet and partially thinned, and is attached in a state of being in close contact with the curved surface of the molded body.

  According to one embodiment of the present invention, it is possible to provide a labeled molded body (molded body with a display section) that has no misalignment of the display section and is excellent in design. That is, in the method for producing a labeled molded article according to the present invention, a specific picture or the like is molded as compared with a method (laminating method) of laminating a long film printed with a display on a surface of a molded precursor. It is easy to provide at a predetermined position, and it is also possible to reduce material costs by suppressing waste of material. Furthermore, according to the present invention, the display label can be adhered closely and attached cleanly along the three-dimensional curved surface of the molded body. Further, for example, by selectively attaching a display label to a part of the molding precursor, preferably on a part where a pattern or the like of the part to be molded is to be provided, for example, the degree of freedom in design design of the molded body is increased. Can do.

Hereinafter, an example of the embodiment will be described in detail with reference to the drawings.
The drawings referred to in the embodiments are schematically described, and the dimensional ratios of the components drawn in the drawings may be different from the actual products. Specific dimensional ratios and the like should be determined in consideration of the following description. In the present specification, the description “approximately **” is intended to include cases where it is recognized as substantially right as well as perfect right, when it is described as an example of substantially right.

  Below, although the labeled molded object by which the display label was stuck to a part of molded object is illustrated, the display label may be stuck on the whole surface of a molded object. For example, when a display label is affixed to the entire surface of the molded part of the molding precursor, and then the molded part is molded into a container shape or the like, the display label is affixed to the entire surface of the molded body. . However, also in this case, for example, since the display label is selectively attached only to the part to be molded of the molding precursor and the periphery thereof, the positional deviation of the display part can be suppressed, and the material cost can be reduced.

FIG.1 and FIG.2 is a figure which shows the molded object 10 with a label which is an example of embodiment.
The labeled molded body 10 includes a molded body 20 and a display label 30 attached to the molded body 20. In this embodiment, the display label 30 is partially attached to the molded body 20 formed in a container shape. The display label 30 has a print layer 33 (see FIG. 3 described later) as a display unit for a product name, a manufacturer name, a logo mark, a pattern, a product description, a campaign notification, etc. It is a label for providing a pattern etc. Although mentioned later in detail, the molded object 20 has the three-dimensional curved surface R, and the display label 30 is stuck in the state closely_contact | adhered to the three-dimensional curved surface R. FIG. A three-dimensional curved surface means a curved surface that cannot be formed by plane deformation, that is, a curved surface that is not a developable surface.

  The molded body 20 includes a bottomed cylindrical portion 21 and is molded into a container shape. The molded body 20 may be made of metal, for example, but in the following, it will be described as a transparent resin molded body (the same applies to molded bodies 41 and 51 described later). The resin which comprises the molded object 20 is not specifically limited, A polyester-type resin, polyolefin-type resin, a polystyrene-type resin etc. can be illustrated. Among them, polyester resins (polyethylene terephthalate (PET) resins) are preferable from the viewpoint of strength, dimensional stability, and moldability of the molded body 20. The bottomed cylindrical portion 21 is formed in a bottomed substantially square cylindrical shape having an internal space capable of accommodating various articles and the like, and one end in the axial direction is open. The bottomed cylindrical portion 21 has a substantially square bottom wall 22 and a side wall 23 erected on the bottom wall 22. In the following, one end in the axial direction where the bottomed cylindrical part is opened is referred to as “upper”, and the bottom wall part side (the other end in the axial direction) is referred to as “lower”.

  The molded body 20 includes a flange portion 24 that protrudes from the upper end portion of the bottomed tubular portion 21, that is, the end portion opposite to the bottom wall portion 22 side of the side wall portion 23, to the outside of the bottomed tubular portion 21. The flange portion 24 is formed over the entire circumferential length of the bottomed cylindrical portion 21. The bottom wall portion 22 and the flange portion 24 are formed substantially in parallel, and the side wall portion 23 is formed substantially perpendicular to the bottom wall portion 22 and the flange portion 24. That is, the molded body 20 is bent substantially at right angles at the boundary between the bottom wall 22 and the side wall 23 and at the boundary between the side wall 23 and the flange 24. Hereinafter, the surface facing the inner side of the bottomed cylindrical portion 21 and the surface of the flange portion continuous therewith are referred to as “inner surface 20a”, and the surface opposite to the inner surface 20a is referred to as “outer surface 20b”.

  The circumferential length of the bottomed cylindrical portion 21 is slightly larger as it approaches the upper end. That is, the angle formed by the bottom wall portion 22 and the side wall portion 23 on the inner surface 20a side and the angle formed by the side wall portion 23 and the flange portion 24 on the outer surface 20b side are both slightly larger than 90 °, and the side wall portion 23 is at the upper end. It inclines so that a part may be located outside the lower end part. Further, on the side wall portions 23 located at the four corners of the bottomed cylindrical portion 21, curved surfaces that are greatly curved outward, that is, curved surfaces along the circumferential direction of the bottomed cylindrical portion 21 are formed. A three-dimensional curved surface R is formed at upper and lower end portions of the four corners of the bottomed cylindrical portion 21 (the boundary between the bottom wall 22 and the side wall 23 and the boundary between the side wall 23 and the flange 24). .

  The display label 30 is partially attached to the surface of the molded body 20. In the present embodiment, the display label 30 is attached to a part of the outer surface 20 b of the molded body 20, for example, about 25% of the outer surface 20 b. The area of the surface (label application surface 25) of the molded body 20 to which the display label 30 is attached is not particularly limited, and for example, the display label 30 may be attached to a range of about 75% of the outer surface 20b. Examples of the shape of the display label 30 include various shapes such as a polygonal shape such as a triangle, a quadrangle, and a pentagon, a circular shape, an elliptical shape, and a shape in which the label edge is cut into a corrugated shape. In the present embodiment, the substantially square display label 30 is illustrated.

  The display label 30 is attached, for example, from the tip of the flange portion 24 to the bottom wall portion 22 beyond the connecting portion between the flange portion 24 and the side wall portion 23. That is, the display label 30 is attached across the bottom wall 22 and the side wall 23 and across the side wall 23 and the flange 24. The display label 30 is affixed along the outer surface 20b including the curved surface of the molded body 20, and the three-dimensional curved surface R is also included in the curved surface. That is, the label affixing surface 25 of the molded body 20 is formed into a three-dimensional curved surface R.

  The display label 30 is attached, for example, in close contact with the outer surface 20b including the three-dimensional curved surface R without having a crease. Here, the eyelid means a streak-like convex portion confirmed with the naked eye. For example, after attaching the display label 30 to the forming precursor, forming a part of the label attaching surface 25 so as to form the three-dimensional curved surface R makes it difficult to apply the label beautifully Also for the curved surface R, it is possible to make the display label 30 be in intimate contact with the display label 30 completely. In addition, by attaching the display label 30 to the three-dimensional curved surface R, the molded body 20 (three-dimensional curved surface R) is reinforced.

In the display label 30, the portion attached to the side wall portion 23 is thinner than the portion attached to the bottom wall portion 22 and the flange portion 24. That is, the display label 30 attached to the molded body 20 is molded together with the display label affixing portion of the molded precursor and partially thinned, and has a thick portion and a thin portion. Label 30 affixed to the molded body 20 has a thickness t ₂ of the patch portion to the sidewall portion 23, of the patch portion to the bottom wall 22 thickness t _1, and the attached portions to the flange portion 24 thinner than the thickness _{t 3 (t 2 <t 1} , t 3). The thickness of the part affixed on the bottom wall part 22 and the flange part 24 is so thin that it approaches the side wall part 23, for example. In other words, the display label 30 is stretched by the molding process of the molding precursor, and the shape and size change before and after molding. The display label 30 after molding is greatly enlarged and partially thin in thickness compared to the display label 30 before molding.

  In the example shown in FIG. 2, the depression and the bulging portion corresponding to the display label 30 are not formed in the molded body 20, but as described later in detail, the label sticking surface 25 of the molded body 20 is depressed and the label sticking surface The range corresponding to the said label affixing surface of the surface (inner surface 20a) on the opposite side to 25 may be bulged.

FIG. 3 is a view showing a cross section of the display label 30 before molding.
The display label 30 includes a label substrate 31, an adhesive layer 32, and a print layer 33 (for example, the same applies to display labels 46, 56, 71, and 72 described later). The label base 31 is a support for the pressure-sensitive adhesive layer 32 and the print layer 33, and the shape of the label base 31 determines the shape of the display label 30. The pressure-sensitive adhesive layer 32 has a function of bonding the display label 30 to the molded body 20. As described above, the print layer 33 is a layer for providing a label with a product name, a manufacturer name, a logo mark, a pattern, a product description, a campaign notification, and the like.

In the example shown in FIG. 3, the pressure-sensitive adhesive layer 32 is formed on one surface of the label base material 31, and the printing layer 33 is formed on the other surface. The printing layer 33 and the pressure-sensitive adhesive layer 32 may be sequentially formed on one surface of the label base 31 (laminated structure of label base 31 / printing layer 33 / pressure-sensitive adhesive layer 32), label base 31 The printing layer 33 may be formed on both sides of the sheet. Further, the label base material 31 may be formed with a layer other than the pressure-sensitive adhesive layer 32 and the print layer 33. The other layers are formed on a metallized layer, a transfer foil layer (transferred by, for example, a cold stamp method or a hot stamp method), a highly decorative decorative layer such as a hologram layer, and the print layer 33 Examples include a protective layer, an anchor coat layer formed between the label substrate 31 and the print layer 33, and the like. Incidentally, the high design property decorative layer is preferably formed on the portion excluding the three-dimensional curved surface R of the shaped body 20, in particular, the thick portion (for example, a thickness t _1, t ₃ portions) of the label It is preferable to form it.

  The label base 31 is made of a resin film. Although a uniaxially or biaxially stretched resin film may be used as the label substrate 31, preferably a substantially non-stretched resin film is used. Here, “substantially unstretched” means that the stretching ratio of the label base material 31 (resin film) is less than 1.05 times in any direction. By using a substantially non-stretched label base material 31 (hereinafter sometimes simply referred to as non-stretched), the display label 30 follows the shape of the molded part 26z (see FIG. 5 described later) during the molding process. Of the display label 30 can be prevented, and breakage or peeling of the display label 30 can be prevented. The thickness of the label substrate 31 is substantially uniform and is not particularly limited, and is, for example, 10 μm to 300 μm, preferably 30 μm to 100 μm.

  The resin film used for the label substrate 31 is not particularly limited. For example, a polyolefin resin such as a polyethylene (PE) resin or a polypropylene (PP) resin, a polyethylene terephthalate (PET) resin, or a polylactic acid (PLA) resin. Select from thermoplastic resins such as polyester resins such as resins, polystyrene resins, polyvinyl chloride resins, polyamide resins, polyimide resins, polyphenylene sulfide resins, acrylic resins, ethylene vinyl acetate copolymers, and various elastomers. The film which consists of 1 type (s) or 2 or more types of mixtures is mentioned. Among them, polyolefin resin films are preferable. One example of a suitable resin film is a non-stretched film (stretching ratio less than 1.05) having a PP resin as a main component because it is flexible and has excellent followability to a curved surface. For example, a combination of a molded body 20 made of a PET-based resin and a display label 30 made of a non-stretched PP-based resin is preferable. The resin film may be a foamed film or a multilayer film (a multilayer film in which a polyolefin layer and another thermoplastic resin layer are laminated).

  The resin film has a tensile strength (film thickness: 70 μm, strength when the length in one direction of the film is extended by 1.05 times) measured according to the film tensile test method of JIS K 7127 is 20 N / 15 mm The following are preferable, and 5N / 15m-16N / 15mm are more preferable. The label substrate 31 may be transparent, translucent, or opaque.

  The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 32 is not particularly limited as long as it has a function of adhering the display label 30 to the molded body 20 (shaped precursor), and various pressure-sensitive adhesives (adhesives) can be used. The pressure-sensitive adhesive layer 32 is formed, for example, by applying a pressure-sensitive adhesive on the entire surface of one side of the label substrate 31. After the display label 30 is peeled off, the pressure-sensitive adhesive layer 32 may be able to be adhered to the adherend again (re-adherable) or may not be able to be adhered again (non-re-adhesion). Examples of adhesives include synthetic rubbers such as styrene-isoprene-styrene block copolymers and styrene-butadiene-styrene block copolymers, acrylic resins, olefin resins, urethane resins, and ultraviolet (UV) curable resins. And ethylene-vinyl acetate copolymer. The pressure-sensitive adhesive may be a heat-sensitive adhesive that exhibits adhesiveness by heating, but is preferably a pressure-sensitive adhesive that has adhesiveness at normal temperature and can adhere to an adherend by pressing. . The thickness of the pressure-sensitive adhesive layer 32 is not particularly limited, but preferably 10 μm to 50 μm.

  The printing layer 33 is formed by, for example, applying printing ink to the other surface of the label base material 31 according to a formation pattern such as a pattern, and then solidifying the ink component by drying or ultraviolet irradiation. As a printing ink used for formation of the printing layer 33, a solvent type ink, an ultraviolet curable ink, etc. can be illustrated. Among them, it is preferable to use an ultraviolet curable ink excellent in heat resistance. By using the ink having high heat resistance, it is possible to suppress the deterioration of the print layer 33 due to the heat at the time of the forming process. The printing layer 33 is formed on the other surface of the label substrate 31 by performing gravure printing, flexographic printing, letterpress rotary printing, or the like using this printing ink. The print layer 33 is formed in advance in a pattern such as a picture that assumes that the display label 30 extends following the shape of the molding target 26z during molding.

  The printing layer 33 not only displays, for example, a pattern, etc., but also displays a background color. In particular, when the label substrate 31 is transparent, it is preferable to form a background print layer. Also, if the print layer 33 is formed on both sides with the background color (masked color) (or with the label base 31 when the label base 31 is opaque), it can be seen from both inside and outside of the molded body 20 It is possible to provide a pattern or the like. The thickness of the printing layer 33 is not particularly limited, but preferably 0.1 μm to 10 μm.

FIG. 4 is a front view of a blister package 11 using the labeled molded body 10.
The blister package 11 includes a labeled molded body 10 and a plate-like member 12 joined to the inner surface 20a of the flange portion 24 of the labeled molded body 10. In the blister package 11, various articles (not shown) are accommodated in the cylinder of the bottomed cylindrical portion 21 of the labeled molded body 10, and the bottomed cylindrical shape is formed by the plate member 12 joined to the flange portion 24. It has a packaging form in which the opening of the part 21 is closed. Examples of the articles contained in the bottomed cylindrical portion 21 include pharmaceuticals, dry batteries, oral hygiene products, cosmetics, machine parts such as screws, foods such as confectionery, and toys. In this case, the bottom wall 22 is used as the front.

  In the example shown in FIG. 4, the hanging hole 13 is formed in the upper part of the plate-like member 12. The plate-like member 12 is, for example, a cardboard, and has a substantially rectangular shape which is longer in the vertical direction than in the left and right in front view. The labeled molded body 10 is provided with a product name, a manufacturer name, a logo, a pattern, a product description, a campaign notice, and the like by the display label 30 attached to a part of the molded body 20 as described above. The portion to which the display label 30 is not attached is transparent, and the article contained in the bottomed cylindrical portion 21 can be visually recognized. The display label 30 can be peeled off, for example, from the molded body 20, and can also be used as a campaign label (application seal) or the like. Since the blister package 11 using the labeled molded body 10 is attached in a state where the display label 30 for displaying a pattern or the like is in close contact with the curved surface of the molded body 10, the appearance is good and the sense of unity between the pattern and the article is good. Is obtained.

  In addition, the labeled molded object 10 can be used also for packages other than the blister package 11. For example, a flexible sheet-like lid member may be joined to the inner surface 20 a of the flange portion 24 and the labeled compact 10 may be applied to a packaging form in which the opening of the bottomed cylindrical portion 21 is covered.

FIG. 5 is a view showing an example of a method of manufacturing the labeled molded body 10.
The manufacturing process of the labeled molded body 10 includes a first step of selectively attaching the display label 30 to a range including the molded portion 26 z of the long resin sheet 26 which is a molded precursor, and the display label 30 And a second step of forming and processing the pasted portion 26z. That is, in the first step, the display label 30 is attached to a part of the resin sheet 26. The entire display label 30, at least the majority (for example, 80% or more) is attached to the molding part 26 z. The to-be-molded part 26z is a part that is molded into the molded body 20 (the labeled molded body 10) in the long resin sheet 26.

  The resin sheet 26 is substantially flat before the second step. Similarly, the display label 30 is substantially flat (the thickness is substantially constant) before the second step. Therefore, it is easy to attach the display label 30 cleanly and neatly in the first step. The resin sheet 26 has a plurality of molded parts 26z along the longitudinal direction, and is molded into a plurality of labeled molded bodies 10. As will be described in detail later, in this manufacturing process, for example, the display label 30 is selectively affixed to a predetermined portion of the molding part 26z, and the molding part 26z is molded to form a specific pattern or the like. Can be accurately provided at a predetermined position of

  In this manufacturing process, the resin sheet 26 is drawn out intermittently at substantially constant intervals, and the first process is performed upstream of the resin sheet 26 in the longitudinal direction, and the second process is performed downstream of the first process. . In the example shown in FIG. 5, one display label 30 is attached to each of the molded parts 26z. The display label 30 may be attached to a predetermined molded portion 26z, but the display label 30 attached to the resin sheet 26 may be detected, that is, the forming position may be determined using the label as a marker. Good. Alternatively, the forming position may be corrected by detecting the display label 30 attached to the resin sheet 26.

  In the first step, as described above, the display label 30 is partially attached to the molded portion 26z of the resin sheet 26. For example, the display label 30 is attached to a range of about 25% of the molding portion 26z including one corner portion only on the first surface 26a of the molding portion 26z having a substantially square shape. In the labeled molded body 10, the display label 30 is pasted up to the tip of the flange portion 24, so that the display label 30 sticks out from the molding target portion 26 z in consideration of a shift in the molding processing position. Is preferred. However, the display label 30 attached to a portion other than the molded portion 26z (hereinafter, referred to as "surplus portion") is slight. That is, since the display label 30 is hardly provided in the surplus part discarded as an unnecessary part, it is possible to greatly suppress the waste of material. For example, when the display label 30 is affixed so as not to reach the edge of the labeled molded body 10, the display label 30 is affixed only to the part to be molded 26z.

  In the first step, the display label 30 is attached to at least one surface of the resin sheet 26 so that the plurality of display labels 30 are arranged at predetermined intervals in the longitudinal direction of the resin sheet 26. In the example shown in FIG. 5, a plurality of display labels 30 are attached to the first surface 26 a of the resin sheet 26 at substantially equal intervals in a line. The plurality of display labels 30 are supplied in a state where they are temporarily affixed onto the long release paper 34 at substantially equal intervals (hereinafter sometimes referred to as “continuous body of display labels 30”). The method of attaching the display label 30 is not particularly limited, but preferably the longitudinal direction of the resin sheet 26 and the longitudinal direction of the continuous body of the display label 30 are substantially parallel, and the continuous body is disposed on the first surface 26a, The display label 30 is attached continuously while feeding out the resin sheet 26. In the present embodiment, the first surface 26 a is the outer surface 20 b of the molded body 20. The longitudinal direction of the resin sheet 26 and the longitudinal direction of the continuous body of the display label 30 are substantially perpendicular to each other, the continuous body is arranged so as to be orthogonal to the first surface 26a, and the display label is fed while the resin sheet 26 is fed out. 30 may be attached.

  In the second step, the molding portion 26z to which the display label 30 is attached is molded to produce the labeled molded body 10. In the present embodiment, the part to be molded 26z is formed so that a part of the label attaching surface 25 is curved, and further, a part of the label attaching surface 25 is a three-dimensional curved surface R. According to the present manufacturing process, after the display label 30 is attached to the substantially flat resin sheet 26, the label attaching surface 25 is curved to follow the shape of the sheet, and the label is expanded to form the three-dimensional curved surface R. Even in the opposite direction, the display label 30 adheres cleanly.

  In the second step, a convex portion protruding toward the first surface 26 a is formed in a part of the molded portion 26 z. This convex portion is the bottomed cylindrical portion 21 of the molded body 20. By forming the bottomed cylindrical portion 21, the resin sheet 26 is bent at a substantially right angle at the boundary portion between the bottom wall portion 22 and the side wall portion 23 and at the boundary portion between the side wall portion 23 and the flange portion 24. A part of 25 becomes a curved surface. In addition, the side wall portions 23 positioned at the four corners of the bottomed cylindrical portion 21 are formed with curved surfaces that are largely curved toward the outside, that is, curved surfaces along the circumferential direction of the bottomed cylindrical portion 21. Furthermore, three-dimensional curved surfaces R are formed at the upper and lower ends of the four corners of the bottomed cylindrical portion 21 (the boundary portion between the bottom wall portion 22 and the side wall portion 23 and the boundary portion between the side wall portion 23 and the flange portion 24). The molding part 26z in which the bottomed cylindrical part 21 is formed is separated from the surplus part of the resin sheet 26 by being punched, for example, in the second step. Thereby, the labeled compact 10 in which the flange portion 24 is formed around the bottomed cylindrical portion 21 is obtained.

  Examples of the method of forming the resin sheet 26 include vacuum forming, pressure forming, and press forming. In any of the methods, the resin sheet 26 softened by heating is brought into close contact with a mold and molded into a container shape or the like. The heating temperature varies depending on the composition of the resin sheet 26 and the like, but is generally 160 ° C. to 190 ° C. When the bottomed cylindrical portion 21 is formed on the substantially flat resin sheet 26 by vacuum molding or the like, the display label 30 extends following the shape of the bottomed cylindrical portion 21. At this time, the side wall portion 23 of the bottomed cylindrical portion 21 is thinner than the bottom wall portion 22 and the flange portion 24, and the portion of the display label 30 attached to the side wall portion 23 is also the bottom wall portion 22 and the flange It is thinner than the portion attached to the part 24.

  According to the above-described manufacturing method, it is possible to more accurately provide a target pattern or the like at a predetermined position of the molded body 20 without the problems as in the above-described laminating method. In addition, according to the above manufacturing method, the display label 30 can be attached only to a portion of the molded body 20 where the pattern or the like is to be provided, so that the pattern or the like can be provided. It is possible to design with a high degree of freedom. Furthermore, since the display label 30 is not affixed to the entire surface of the resin sheet 26 as in the above-described laminating method, there are few materials discarded as surplus parts, and the material cost can be greatly reduced.

  When attaching the display label 30 to the surface of the molded body 20, it is difficult to cleanly attach the display label 30 cleanly along the three-dimensional curved surface R, but according to the above manufacturing method, the three-dimensional curved surface R In addition, it is possible to make the display label 30 be in intimate contact with the display label 30 without any defects. Further, the display label 30 can be peeled off, for example, from the surface of the molded body 20, and can also be used as a campaign label or the like.

6 and 7 are diagrams showing a modified example (molded body 10x with a label) of the above embodiment.
The labeled molded body 10x is different from the labeled molded body 10 in that a plurality of (for example, two) display labels 30 are attached to the outer surface 20b of the molded body 20. Each display label 30 has substantially the same shape as each other, and is affixed to opposite corners of the bottomed cylindrical portion 21. The attachment form of each display label 30 on the outer surface 20b is the same as in the case of the labeled molded product 10, and is applied in the range of about 25% of the outer surface 20b. It is covered with a display label 30.

  The labeled compact 10x differs from the labeled compact 10 in that the display label 30 is further attached to the inner surface 20a of the compact 20. That is, in the labeled molded body 10x, a total of four display labels 30 are attached to each surface of the molded body 20, two each. The display label 30 affixed to the inner surface 20 a overlaps the display label 30 affixed to the outer surface 20 b in the thickness direction of the molded body 20. By sticking the display label 30 on both sides of the molded body 20, a picture or the like can be provided on any of the inside and the outside of the molded body 20.

  The plurality of display labels 30 may have different shapes and sizes from one another, and the pasting position on the molded body 20 may be changed as appropriate. For example, the display label 30 attached to the inner surface 20a and the display label 30 attached to the outer surface 20b may not overlap each other, and the number of display labels 30 attached to the inner surface 20a side and the outer surface 20b side is different. Also good.

FIG. 8 is a diagram illustrating an example of a method of manufacturing the labeled molded body 10x.
Like the labeled molded body 10, the labeled molded body 10x selectively adheres the display label 30 to the range including the molded portion 26z of the long resin sheet 26, and the display label 30 is adhered. It manufactures by molding-processing the to-be-shaped part 26z. However, in the manufacturing process of the labeled molded body 10x, in the first process, a plurality of display labels 30 are affixed to one surface of each molded part 26z of the resin sheet 26. In FIG. 8, the display label 30 is attached to the first surface 26 a of the resin sheet 26, but the display label 30 is attached to the second surface 26 b of the resin sheet 26 as in the first surface 26 a. Do. As illustrated in FIG. 8, according to the present manufacturing process, the range and position of the design etc. provided on the molded body can be easily made by appropriately changing the number of continuous labels of the display label, the application position of the display label, etc. It can be changed.

FIG. 9 is a diagram illustrating a labeled molded body 40 which is another example of the embodiment.
The labeled molded body 40 includes a molded body 41 and a display label 46 attached to the molded body 41. The molded body 41 includes a bottomed cylindrical portion 42 and a flange portion 45, but differs from the molded body 20 in that the bottomed cylindrical portion 42 is formed in a substantially cylindrical shape. In the package using the labeled formed body 40, for example, various articles are stored in the cylinder of the bottomed cylindrical portion 42 of the labeled formed body 40, and the opening of the bottomed cylindrical portion 42 is separately , And used in the form of a closed package with a lid or the like (not shown). The bottomed cylindrical portion 42 includes a substantially circular bottom wall portion 43 and a side wall portion 44 erected on the bottom wall portion 43. The flange portion 45 extends outward from the upper end of the bottomed cylindrical portion 42 and is formed over the entire circumferential length of the bottomed cylindrical portion 42 as in the case of the molded body 20. The formed body 41 is bent substantially at right angles at the boundary between the bottom wall 43 and the side wall 44 and at the boundary between the side wall 44 and the flange 45, and circumferentially on the upper and lower end of the bottomed cylindrical portion 42. A three-dimensional curved surface R is formed along.

  The display label 46 is partially affixed to at least one surface (inner surface and / or outer surface) of the molded body 41, and is affixed to, for example, a range of about 75% of the surface. The display label 46 is attached, for example, across the bottom wall 43 and the side wall 44 and across the side wall 44 and the flange 45 and is in intimate contact with the three-dimensional curved surface R as well. . Further, in the display label 46, the portion attached to the side wall portion 44 is thinner than the portion attached to the bottom wall portion 43 and the flange portion 45.

  As with the labeled molded bodies 10 and 10x, the labeled molded body 40 was selectively pasted with the display label 46 in a range including the molded portion of the long resin sheet, and the display label 46 was pasted. It manufactures by molding-processing a to-be-shaped part. In the second step, the manufacturing process of the labeled molded body 40 is that the molded portion of the substantially flat resin sheet to which the display label 46 is attached is molded into a bottomed cylindrical shape. Different from the 10x case.

  FIG.10 and FIG.11 is a figure for demonstrating the shape of the display-labeled molded object obtained by shape | molding the shaping | molding precursor of a flat sheet shape. In the example shown in FIG. 10 and FIG. 11, the resin sheet 70 (the forming precursor with a display label) to which the display labels 71 and 72 are attached is vacuum formed. The display label 72 is attached to the first surface 70a of the resin sheet 70, and the display label 71 is attached to the second surface 70b.

  In the example shown in FIG. 10, a substantially flat resin sheet 70 is molded using a mold 73 having a recess 74 (see FIG. 10A), and a display having a bottomed cylindrical portion 62 and a flange portion 65. A labeled compact 60 is produced (see FIG. 10 (b)). The recess 74 is a recess for forming the bottomed cylindrical portion 62 of the molded body 61. By vacuuming the space between the heat-softened resin sheet 70 and the mold 73 to bring the second surface 70b of the resin sheet 70 into close contact with the mold 73, the sheet is expanded toward the second surface 70b and the bottom is closed. The cylindrical portion 62 is formed. In this case, the display label 71 contacts the mold 73 and the display label 72 does not contact the mold 73.

  According to the above forming method, at least a part of the display label 71 in the thickness direction is embedded in the molded body 61, and a recess is formed in the entire label pasting surface 66, for example, formed around the display label 71 The level difference with the outer surface 61 b of the molded body 61 is reduced, or the level difference is almost eliminated. The surface of the molded body 61 opposite to the label application surface 66 (inner surface 61a) bulges in a range corresponding to the label application surface 66, and a bulge portion 68 is formed on the inner surface 61a. By forming the depressions on the label pasting surface 66, the display label 71 becomes difficult to peel off. On the other hand, the display label 72 not in contact with the mold 73 is not buried in the molded body 61, and a bulging portion is not formed on the outer surface 61b located on the opposite side of the label pasting surface 67. That is, the display label 71 affixed to the outer surface 61 b is difficult to peel off, and the display label 72 affixed to the inner surface 61 a is easier to peel off than the display label 71.

  In the example shown in FIG. 11, a substantially flat resin sheet 70 is molded using a mold 93 having convex portions 94 (see FIG. 11A), and includes a bottomed cylindrical portion 82 and a flange portion 85. A labeled body 80 is produced (see FIG. 11 (b)). The convex portion 94 is a protrusion for forming the bottomed cylindrical portion 82 of the molded body 81. By vacuuming the space between the heat-softened resin sheet 70 and the mold 93 and bringing the second surface 70b of the resin sheet 70 into close contact with the mold 93, the sheet bulges to the first surface 70a side and the bottom is closed. The cylindrical portion 82 is formed.

  Also in this case, the display label 71 is in contact with the mold 93, and at least a part of the display label 71 in the thickness direction is embedded in the molded body 81, and a depression is formed in the entire label pasting surface 86. A bulging portion 88 is formed in the outer surface 81 b of the molded body 81 on the opposite side of the label application surface 86 in a range corresponding to the label application surface 86. On the other hand, the display label 72 is not embedded in the molded body 81, and a bulging portion is not formed on the inner surface 81a located on the opposite side of the label pasting surface 87. That is, contrary to the example shown in FIG. 10, the display label 72 attached to the inner surface 81a is less likely to be peeled off, and the display label 71 attached to the outer surface 81b is easier to peel off than the display label 72.

  10 and 11 show examples in which the display labels 72 and 71 are attached to the first surface 70a and the second surface 70b of the resin sheet 70, respectively. Can be changed.

FIG. 12 is a diagram illustrating a labeled molded body 50 as another example of the embodiment.
The labeled molded body 50 includes a bottomed substantially cylindrical molded body 51 and a display label 56 attached to the molded body 51. The formed body 51 is positioned between the trunk 52 with the largest circumferential length and the neck 53 to which a cap (not shown) is attached smaller than the trunk 52, and is positioned between the trunk 52 and the neck 53 and approaches the neck 53 And a shoulder 54 which is gradually reduced in diameter as it is reduced. A three-dimensional curved surface R is formed along the circumferential direction at the boundary between the body 52 and the shoulder 54 of the molded body 51. The display label 56 is releasably attached across the body 52 and the shoulder 54 on the outer surface of the molded body 51 and is in intimate contact with the three-dimensional curved surface R as well.

FIG. 13 is a view showing an example of a method of manufacturing the labeled molded body 50. As shown in FIG.
The labeled compact 50 is manufactured by selectively attaching the display label 56 to the portion to be molded of the parison 57, which is a forming precursor, and molding and processing the portion to which the display label 56 is affixed. The parison 57 is a resin molding precursor produced by, for example, injection molding, and has a substantially cylindrical shape with a bottom instead of a flat sheet shape. In the first step (see FIG. 13A), a display label 56 is affixed to a part to be molded of the parison 57, that is, a part that becomes the body 52 and the shoulder 54 of the molded body 51. That is, unlike the above embodiments, the labeling surface of the molding precursor is a curved surface. A new curved surface is formed on the label application surface by blow molding described later (a part of the label application surface is curved).

  In the second step (see FIG. 13B), the parison 57 to which the display label 56 is attached is blow-molded to produce a labeled molded body 50. Specifically, by blowing air into the heated and softened parison 57 and inflating it so that it is in close contact with the mold 58, a body 52 and a shoulder 54 are formed, and a three-dimensional curved surface R is formed at the boundary. The The display label 56 extends following the expansion of the parison 57 and adheres to the surface of the molded body 51 including the three-dimensional curved surface R.

  In the above embodiment, the three-dimensional curved surface R is formed at the boundary between the bottomed cylindrical portion and the flange portion, but the three-dimensional curved surface R is, for example, a hemispherical (dome-shaped) convex portion Or it may be a curved surface formed by a recess. The hemispherical convex portions or concave portions may have various sizes. For example, a display label may be attached to a surface on which a plurality of small convex portions or concave portions, or both convex portions and concave portions are formed. Moreover, the number of adhering display labels and the adhering surface can be changed variously according to the decoration application.
