Description

[Technical Field]

[0001] The present invention provides a label-attached pulp molding having a window. Do Regarding. [Background technology]

[0002] Pulp molds that are designed to be able to hold contents have been widely used in the past, and one known example is a labeled pulp mold in which a hole is provided in the pulp mold and a label made of a transparent film is attached to cover the hole, creating a window, so that the contents can be seen from outside the opaque pulp mold.

[0003] Furthermore, for example, Japanese Patent Application Laid-Open No. 2014-144612 (Patent Document 1) discloses a pulp mold in which a hole is provided in the pulp mold and the hole is covered with a transparent film to provide a window. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-144612 Summary of the Invention [Problem to be solved by the invention]

[0005] Here, in labeled pulp molds obtained by creating a hole in a pulp mold and attaching a label made of a transparent plastic film to cover the hole, it is difficult to attach the label along the curved surface of the pulp mold, and there is a problem that the feel and appearance of the surface of the labeled pulp mold are impaired due to wrinkles and folds that occur in the label where it is attached along the curved surface.

[0006] Furthermore, when manufacturing a pulp mold provided with a window portion as disclosed in Patent Document 1, first, a transparent substrate made of a thermoplastic film is placed above a hole portion provided in the pulp mold, and then this substrate is heated and softened and then sucked toward the pulp mold by vacuuming or the like, so that the substrate is attached to the pulp mold so as to cover the hole portion.

[0007] However, when a pulp mold having a window portion is manufactured according to the above-described method, the thermoplastic film may not conform to the surface shape of the pulp mold, resulting in wrinkles and folds. This causes wrinkles and folds in the thermoplastic film at the portions attached to the curved surfaces of the pulp mold, impairing the feel and appearance of the surface of the pulp mold having the window portion.

[0008] Furthermore, when a pulp mold having a window portion is manufactured according to the above-described method, a large step occurs at the boundary between the portion of the pulp mold where the thermoplastic film is attached and the portion where it is not attached, which causes problems such as impairing the feel and appearance of the surface.

[0009] Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to improve the smoothness of the surface of a labeled pulp mold having a window portion. [Means for solving the problem]

[0010] A labeled pulp mold according to a first aspect of the present invention includes a pulp mold and a label. The pulp mold has a hole. The label has a base material and an adhesive layer provided on one main surface of the base material, and is attached to the pulp mold via the adhesive layer. The label includes a covering area that covers the hole. The pulp mold has a curved surface portion that is curved in multiple directions. In the labeled pulp mold according to the first aspect of the present invention, a portion of the label that corresponds to the curved surface portion is attached to the curved surface portion with a drawing rate of 10% to 50%, and a window portion that allows one side of a pair of main surfaces of the label to be seen from the other side through the label is provided in at least a part of the covering area.

[0011] A labeled pulp mold according to a second aspect of the present invention includes a pulp mold and a label. The pulp mold has a hole. The label has a base and an adhesive layer provided on one main surface of the base, and is attached to the pulp mold via the adhesive layer. The label includes a covered area that covers the hole. The pulp mold includes an attachment surface to which the label is attached and an exposed surface to which the label is not attached. At the boundary between the attachment surface and the exposed surface, the attachment surface is recessed from the exposed surface, thereby providing a step in the pulp mold. In the labeled pulp mold according to the second aspect of the present invention, the label is attached to the pulp mold with at least a portion of the label in its thickness direction recessed into the step, and a window that allows the label to be viewed from one side of the pair of main surfaces of the label to the other side is provided in at least a portion of the covered area.

[0012] In the labeled pulp mold according to the first and second aspects of the present invention, the base material may be made of light-transmitting paper.

[0013] In the labeled pulp mold according to the first and second aspects of the present invention, the hiding power of the substrate is preferably 40% or less.

[0014] In the labeled pulp mold based on the first and second aspects of the present invention, the label may further have a shielding layer, and when viewed from the side where the label is attached to the pulp mold, the peripheral portion of the covered area may be covered by the shielding layer, so that the window portion may be provided in a portion of the covered area other than the peripheral portion.

[0015] The method for manufacturing a labeled pulp mold according to the present invention includes the following steps. (a) A step in which a pulp mold having holes formed therein is prepared. (b) A step in which a label is provided that has a substrate and an adhesive layer disposed on one major surface of the substrate. (c) A step of attaching the label to the pulp mold via the adhesive layer so as to cover the hole.

[0016] Here, the label is such that one of a pair of main surfaces of the label can be seen from one side to the other side through the label.

[0017] In the method for manufacturing a labeled pulp mold according to the present invention, in the step of attaching the label to the pulp mold, the label is attached to the pulp mold by pressing the label in a laminated state on the pulp mold, thereby forming a window portion in at least a part of the covered area of ​​the label, which is the portion that covers the hole. [Effects of the Invention]

[0018] According to the present invention, it is possible to improve the smoothness of the surface of a labeled pulp mold having a window portion. [Brief explanation of the drawings]

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following embodiment 1 and its modifications exemplify the case where the present invention is applied to a labeled pulp mold configured to be able to accommodate a foundation and a puff, and the following embodiment 2 exemplifies the case where the present invention is applied to a labeled pulp mold configured to be able to accommodate a pouch. In the following embodiments, the same or common parts are denoted by the same reference numerals in the drawings, and their description will not be repeated.

[0021] (Embodiment 1) FIG. 1 shows the shape and configuration of a labeled pulp mold according to a first embodiment. FIG. 1(A) is a perspective view of the labeled pulp mold with an upper container portion, which serves as an openable lid, closed, and FIG. 1(B) is a perspective view of the labeled pulp mold with the upper container portion open. FIG. 2 is a plan view of the labeled pulp mold shown in FIG. 1(A). FIG. 3 is a cross-sectional view of the labeled pulp mold shown in FIG. 1(A). FIG. 3(A) is a cross-sectional view taken along line III-III in FIG. 1(A). FIG. 3(B) is an enlarged cross-sectional view of a main portion of the vicinity of a hole in FIG. 3(A). FIG. 4 is a plan view of the pulp mold shown in FIG. 1. First, a labeled pulp mold 1A according to this embodiment will be described with reference to FIGS. 1 to 4. In Figures 1 and 2, in order to make it possible to understand the correspondence between the pulp mold 2A and the label 3A attached thereto by referring to Figures 1 and 2, the surface of the pulp mold 2A in the part that is covered by the label 3A and therefore cannot be directly seen is shown schematically by making the label 3A transparent (the same applies to Figures 12, 16, and 17 described below).

[0022] As shown in FIGS. 1 to 3, the labeled pulp mold 1A is a container for containing flat contents such as foundation and a puff, and includes a pulp mold 2A and a label 3A.

[0023] Pulp mold 2A has an overall generally rectangular shape in a plan view when closed, and includes upper container portion 21 that is open at the bottom, lower container portion 22 that is open at the top, and hinge portion 23 that rotatably connects upper container portion 21 and lower container portion 22. Lower container portion 22 is provided with two recesses 22a that face upper container portion 21 when upper container portion 21 is closed. When upper container portion 21 is closed, these two recesses 22a, together with upper container portion 21, define two storage spaces 20 that store the contents, foundation and puff.

[0024] As shown in FIG. 4, the upper container portion 21 of the pulp mold 2A includes a substantially flat portion and curved portions located around the flat portion, thereby forming a concave portion on the inner surface of the upper container portion 21. The central portion of the outer surface of the upper container portion 21 is configured to have a substantially flat shape, and the four corners of the periphery of the outer surface of the upper container portion 21 include curved portions formed of surfaces curved in multiple directions. The periphery other than the four corners has a curved portion formed of a surface curved in one direction. For ease of explanation, the curved portion of the upper container portion 21 formed of the curved surfaces curved in multiple directions will be referred to as the first portion X, and the remaining portions (i.e., the substantially flat portion and the curved portion of the periphery formed of a surface curved in one direction) will be referred to as the second portion Y. Note that in FIG. 4, the first portion X is shaded darker and the second portion Y is shaded lighter for ease of understanding.

[0025] As shown in FIGS. 1 to 4, a hole 21a having a substantially rectangular shape in plan view is provided in the substantially planar portion of the second portion Y of the upper container portion 21 at a position facing the storage space 20 when the upper container portion 21 is closed (at a position where the color of the foundation, etc., can be seen from the outside in the labeled pulp mold 1A according to this embodiment). The hole 21a constitutes a window 31a through which the storage space 20 can be seen from the outside, as described below. The outer shape of the hole 21a in plan view may be changed as appropriate depending on the configuration of the recess 22a of the lower container portion 22, and may be, for example, a substantially circular shape, a substantially elliptical shape, a polygonal shape, or the like. Note that in FIGS. 1A and 2, the hole 21a is indicated by an imaginary line (a two-dot chain line) (the same applies to FIGS. 12, 13, 16A, and 17, which will be described later).

[0026] The raw material for pulp mold 2A is wastepaper pulp obtained by subjecting used printed paper, such as newspaper, flyers, medium-quality paper, and fine paper, to wet disintegration and screening processes, or deinked wastepaper pulp obtained by subjecting the above processes to deinking and bleaching processes in addition, or cellulose pulp such as bleached pulp or unbleached pulp. Pulp mold 2A is produced by molding a pulp slurry, which is made by adding sizing agents, fillers, dyes, fixing agents, and waterproofing agents to these pulps as appropriate, into the desired shape.

[0027] Instead of the various pulps mentioned above, virgin pulp or non-wood pulp such as bagasse, which is sugarcane waste, or bamboo may be used. In addition, any pulp may contain a small amount (preferably about 5% or less) of synthetic resin.

[0028] As shown in Figures 1 to 3, the label 3A is a sheet-like label attached to the entire outer surface of the upper container portion 21 of the pulp mold 2A, and includes a base material 3a and an adhesive layer 3b provided on one main surface of the base material 3a (see Figure 3(B) in particular). Thus, one of the pair of main surfaces of the label 3A, the first main surface 3(1), is defined by the base material 3a, and the other, the second main surface 3(2), is defined by the adhesive layer 3b. For ease of understanding, in Figure 2, the portion of the label 3A attached to the first portion X of the upper container portion 21 is dark-colored, and the portion attached to the second portion Y of the upper container portion 21 is light-colored (the same applies to Figures 12 and 17 described below).

[0029] The outer shape of the label 3A when viewed from above may be changed as appropriate to match the outer shape of the upper container portion of the pulp mold 2A, and may be, for example, a substantially circular shape, a substantially elliptical shape, a polygonal shape, or the like.

[0030] The substrate 3a is preferably made of a paper material. The substrate 3a is preferably made of a material with a hiding power of 90% or less, and more preferably a material with a hiding power of 40% or less. This allows the label 3A, consisting of the substrate 3a and the adhesive layer 3b, to be visible from the first main surface 3(1) to the second main surface 3(2) of the label 3A through the label 3A. The hiding power of the substrate refers to the ability of the substrate to conceal the color or color difference of the base material.

[0031] An example of a member having the above-mentioned hiding power is a member having optical transparency. An example of a member having optical transparency and having a hiding power of 90% or less is a material having a basis weight of 50 g / m. 2 More than 100g / m 2 The following semi-gloss bleached kraft paper and cellophane, with a basis weight of 40 g / m 2 The following glassine papers are listed, among which cellophane and those with a basis weight of 40 g / m 2The glassine paper described below has a hiding power of 40% or less. Furthermore, the member having the above-mentioned hiding power may be a so-called meshed paper, which is a non-light-transmitting paper with a plurality of through holes. The meshed paper is configured so that its hiding power can be adjusted appropriately by changing the size and number of the through holes. The hiding power of the members listed above is based on the results of the verification test described below.

[0032] The basis weight of the paper member used as the base material 3a is 20 g / m 2 More than 100g / m 2 It is preferable that the thickness is not more than 30 μm. This effectively prevents the label 3A from being unintentionally broken and from being deformed in a manner that does not conform to the surface of the pulp mold 2A. The thickness of the paper member used as the base material 3a is preferably not less than 30 μm and not more than 150 μm, and more preferably not less than 50 μm and not more than 130 μm.

[0033] In this embodiment, cellophane, which has excellent transparency, is used as the base material 3a. When a paper member such as cellophane is used as the base material 3a in this manner, most of the labeled pulp mold 1A according to this embodiment, including the pulp mold 2A, is made of paper members, and therefore the labeled pulp mold 1A can be an environmentally friendly container in which the use of synthetic resin is significantly reduced.

[0034] The substrate 3a is not limited to being made of paper, and a plastic film, etc. may be used as the substrate 3a. Examples of films that can be used for the substrate 3a include polyester-based films such as polyethylene terephthalate and polylactic acid, polyolefin-based films such as polypropylene and high-density polyethylene, and styrene-based films such as styrene-butadiene copolymer, and have a thickness of 10 μm or more and 100 μm or less.

[0035] The adhesive layer 3b is preferably transparent and thermally adhesive. Specifically, the adhesive layer 3b is preferably a thermoplastic resin such as low density polyethylene (LDPE) or ethylene-vinyl acetate (EVA), which is a resin with thermal adhesive properties. However, it may also be an acrylic or urethane resin with good adhesive properties. Furthermore, when cellophane is used as the base material 3a, it is preferable to use an acrylic resin or vinylidene chloride resin as the adhesive layer 3b. In this way, moisture resistance and thermal adhesive properties can be imparted to the cellophane that constitutes the base material 3a.

[0036] Furthermore, the adhesive layer 3b may be a biodegradable resin such as PBS (Poly Butylene Succinate) or PLA (Poly Lactic Acid) made from plant-derived raw materials, which can reduce the use of petroleum-derived materials. The adhesive layer 3b may also contain a tackifier, a lubricant, or the like.

[0037] The adhesive layer 3b may be provided on the main surface of the base material 3a by extrusion lamination of the resin or the like constituting the adhesive layer 3b onto the base material 3a, or by coating the resin or the like in a solution or emulsion state onto the base material 3a and drying it, etc. The thickness of the adhesive layer 3b is preferably 0.5 μm or more and 20 μm or less.

[0038] Here, the adhesive layer 3b may be provided not only on one of the pair of main surfaces of the base material 3a but also on both of the pair of main surfaces. In this configuration, when wrinkles or folds occur in the label 3A as described below, the main surfaces of the parts that define these can be adhered to each other and fixed in a folded state.

[0039] 1 to 3, the label 3A attached to the upper container portion 21 includes a covering region 31 that covers the hole 21a of the upper container portion 21. Here, as described above, the label 3A is configured so that the second main surface 3(2) can be seen from the first main surface 3(1) through the label 3A. By configuring it in this manner, the covering region 31 of the label 3A, which is the portion that covers the hole 21a, is provided with a window portion 31a that allows the storage space 20 to be seen from the outside.

[0040] 3(B), when the label 3A is attached to the pulp mold 2A by pressing as described below, the covered area 31 of the label 3A, which is the portion that covers the hole 21a, is attached to the pulp mold 2A with at least a portion of the covered area 31 in the thickness direction entering the hole 21a. As a result, the covered area 31 of the label 3A is positioned as a whole further back than the portion of the label 3A other than the covered area 31.

[0041] Furthermore, as shown in Figures 2 and 4, the label 3A is attached via an adhesive layer 3b to the entire outer surface of the upper container portion 21, including the first portion X, which is a curved portion consisting of a curved surface that curves in multiple directions, and the second portion Y, which is the other portion.

[0042] Here, because the first portion X is a curved portion consisting of a curved surface that curves in multiple directions, if the label 3A is attached to the first portion X without any treatment, the label 3A will easily wrinkle or fold over. In this regard, in the labeled pulp mold 1A according to this embodiment, the label 3A is attached so that the drawing rate of the portion of the label 3A corresponding to the first portion X is a predetermined value, and further, a predetermined design is applied to the portion of the label 3A corresponding to the first portion X, thereby solving the above-mentioned problem.

[0043] Specifically, in labeled pulp mold 1A, label 3A is attached to pulp mold 2A by pressing, so that the portion of label 3A corresponding to first portion X is attached to first portion X with a squeezing rate of 10% or more and 50% or less, and the portion of label 3A corresponding to second portion Y is attached to second portion Y with a squeezing rate of less than 10%.

[0044] The drawing rate can be calculated from the circumferential length of the label 3A affixed to the pulp mold 2A and the circumferential length of the area of ​​the pulp mold 2A to which the label 3A is affixed. If the circumferential length measured at a position on the pulp mold 2A to which the label 3A is affixed is P1, and the circumferential length of the label 3A affixed to the pulp mold 2A at a position corresponding to the measurement position of P1 is P2, the drawing rate can be calculated using the following formula 1. Note that when calculating the drawing rate, it is preferable to calculate P2 in short units, such as 2 mm.

[0045] (Formula 1) Drawing ratio = 100 - (P1 / P2 x 100) Furthermore, a design is applied to the portion of label 3A corresponding to first portion X so that wrinkles and overlaps of label 3A are less noticeable. Examples of such designs include wood grain, stone grain, stone wall, rock surface, marble, sky, sand, wave, woven fabric, small floral, grass and flower, tree, arabesque, small pattern, botanical, paisley, camouflage, polka dot, watercolor, and marble patterns, and it is preferable that one of these designs is applied to the portion of label 3A corresponding to first portion X.

[0046] Here, wood grain is a pattern made up of tree rings, fibers, vessels, etc. that appear in the cross section of lumber; stone grain is a pattern that shows the bare surface of natural stone or brick; stone wall pattern is a pattern that shows the atmosphere of stones of various shapes stacked on top of each other on a castle wall or the like; sky pattern is a pattern that shows a scene of various clouds floating in the blue sky or a cloudy sky; wave pattern is a pattern that shows a choppy ocean or ripples; woven pattern is a pattern that shows the texture of woven cotton or linen thread or woven straw or bamboo; dot pattern is a pattern that includes polka dots and is called shampoo dot, bubble dot, coin dot, or random dot; and watercolor pattern is an atmospheric pattern created by painting shades of watercolor paint.

[0047] Furthermore, the design applied to the portion of label 3A corresponding to first portion X is not limited to the above-mentioned designs, and may be any design that makes wrinkles and overlaps of label 3A less noticeable. In other words, the design applied to the portion of label 3A corresponding to first portion X may be, in addition to the above-mentioned designs, any of the following: a pattern identical to the background pattern of pulp mold, a design with natural objects scattered throughout, and a continuous pattern in which substantially identical unit designs are repeatedly arranged.

[0048] Here, a pattern identical to the background pattern of the pulp mold refers to a pattern that appears on the surface of the pulp mold due to the irregular intertwining of various fine fibers of the paper and pulp that make up the pulp mold. Furthermore, substantially identical unit designs may include not only unit designs that are completely identical in size, shape, and color, but also unit designs that are not identical in at least one of size, shape, and color. Substantially identical unit designs may also include, for example, different types of flowers or plants arranged as unit designs.

[0049] The above-described designs may be provided on one or both of the pair of main surfaces of the base material 3a of the label 3A. When the designs are provided on the main surface of the base material 3a on which the adhesive layer 3b is to be provided, the designs may first be applied to the main surface of the base material 3a, and then the adhesive layer 3b may be applied over the designs. The application of such designs may be performed using a suitable method, depending on the base material 3a, the design, etc., from among known printing methods such as gravure printing, flexographic printing, offset printing, screen printing, and inkjet printing.

[0050] The portion of label 3A corresponding to first portion X may be plain and have no design. For example, if highly transparent cellophane is used as base material 3a of label 3A, the background pattern of pulp mold 2A can be seen through it, and the luster and other characteristics unique to cellophane can be imparted to first portion X.

[0051] Fig. 5 is a flow diagram showing a method for manufacturing a labeled pulp mold according to this embodiment, and Figs. 6 to 8 are schematic cross-sectional views showing some of the steps shown in Fig. 5. Next, the method for manufacturing a labeled pulp mold according to this embodiment will be specifically described with reference to Figs. 5 to 8.

[0052] Here, Figure 6 is a diagram showing a cross section of the pulp mold 2A, label 3A, and the first mold 100 and second mold 110 described later at a position corresponding to line VI-VI shown in Figure 1(B) (the same applies to Figures 7 and 8).

[0053] 5, in the manufacturing method of labeled pulp mold 1A according to this embodiment, first, a pulp mold 2A having holes 21a and configured to be able to be compressed by a pressing step (step S5) described later is prepared (step S1). Next, a label 3A having an outer shape large enough to cover the entire outer surface of upper container portion 21 of pulp mold 2A having holes 21a is prepared (step S2).

[0054] 5 and 6, the pulp mold 2A is set in a first mold 100 having a shape that conforms to the shape of the pulp mold 2A when the upper container portion 21 is open (step S3). Here, a shape that conforms to the shape of the pulp mold 2A means a shape that substantially conforms to the shape of the labeled pulp mold 1A as a product, and does not mean a shape that completely matches the shape of the pulp mold 2A before a step (step S5) in which the pulp mold 2A and the label 3A described below are pressed by the second mold 110. In other words, a shape that conforms to the shape of the pulp mold 2A means a shape that conforms to the pulp mold 2A and the label 3A attached thereto after they are pressed by the second mold 110 together with the label 3A in step S5 described below (i.e., after they are compressed and deformed by pressing).

[0055] 6, the first mold 100 is provided with a first convex portion 101 and a second convex portion 102 so as to protrude from one of a pair of main surfaces thereof. The first convex portion 101 has a shape that follows the concave portion included in the upper container portion 21 of the pulp mold 2A, and the second convex portion 102 has a shape that follows the concave portion 22a of the lower container portion 22 of the pulp mold 2A.

[0056] The pulp mold 2A is set in the first mold 100 with the upper container portion 21 open so that the concave portion included in the upper container portion 21 abuts against the first convex portion 101 and the concave portion 22a of the lower container portion 22 abuts against the second convex portion 102.

[0057] Next, as shown in FIGS. 5 and 6, the label 3A is positioned and placed on the pulp mold 2A (step S4).

[0058] 6, with the pulp mold 2A set in the first die 100, the label 3A is positioned relative to the upper container portion 21 of the pulp mold 2A so that the second main surface 3(2) on which the adhesive layer 3b is provided faces the upper container portion 21 of the pulp mold 2A and so that the label 3A covers the hole 21a of the upper container portion 21 in a step (step S5) described later in which the pulp mold 2A and the label 3A are pressed by the second die 110. In this way, the label 3A is placed between the first die 100 and the second die 110 described later.

[0059] Next, as shown in FIGS. 5 and 7, the label 3A is attached to the pulp mold 2A by being pressed by the second die 110 (step S5).

[0060] Specifically, as shown in Fig. 7, with the label 3A positioned relative to the pulp mold 2A, the label 3A is pressed toward the pulp mold 2A (i.e., in the direction of arrow AR1 shown in Fig. 7) by a second die 110 having a shape that conforms to the shape of the pulp mold 2A. As a result, the label 3A is attached to the upper container portion 21 so as to cover the hole 21a.

[0061] Here, the shape of the second die 110 that conforms to the shape of the pulp mold 2A means a shape that substantially conforms to the shape of the labeled pulp mold 1A as a product, and does not mean a shape that completely matches the shape of the pulp mold 2A before step S5. In other words, the shape that conforms to the shape of the pulp mold 2A means a shape that conforms to the pulp mold 2A and the label 3A attached thereto after being pressed by the second die 110 together with the label 3A in step S5 (i.e., after being compressed and deformed by pressing, as will be described later).

[0062] In addition, second mold 110 has a first recessed portion 111 and a second recessed portion 112 on one of its pair of main surfaces facing first mold 100. First recessed portion 111 has a shape that follows the outer surface of the recessed portion included in upper container portion 21 of pulp mold 2A (i.e., the upper surface shown in FIG. 7), and second recessed portion 112 has a shape that follows the outer surface of recess 22a of lower container portion 22 of pulp mold 2A (i.e., the upper surface shown in FIG. 7).

[0063] By pressing with the second die 110 configured in this manner, the pulp mold 2A and the label 3A are sandwiched in a stacked state between the first die 100 and the second die 110. As a result, the label 3A is attached to the upper container part 21 via the heat-adhesive adhesive layer 3b provided on the second main surface 3(2) side so as to cover the entire outer surface of the upper container part 21 in which the hole 21a is provided.

[0064] As described above, the label 3A is configured so that the first main surface 3(1) side of the label 3A and the second main surface 3(2) side of the label 3A can be seen through the label 3A. As a result, the covered region 31 of the label 3A, which is the portion that covers the hole 21a, is provided with a window 31a that allows the storage space 20 to be seen from the outside when the upper container portion 21 is closed.

[0065] Furthermore, when the label 3A is attached to the pulp mold 2A by pressing, the covered region 31 of the label 3A, which is the portion covering the hole 21a, is attached to the pulp mold 2A so that the adhesive layer 3b follows the edge of the hole 21a. As a result, the covered region 31 of the label 3A is positioned at a position that is set back as a whole from the portion of the label 3A other than the covered region 31 (see FIG. 3(B)).

[0066] Furthermore, by pressing the label 3A onto the pulp mold 2A, the portion of the label 3A corresponding to the first portion X of the upper container portion 21 is attached to the first portion X with a squeezing rate of 10% or more and 50% or less, and the portion of the label 3A corresponding to the second portion Y of the upper container portion 21 is attached to the second portion Y with a squeezing rate of less than 10%.

[0067] In step S5, the pressing temperature using the second die 110 is preferably approximately 70°C to 200°C, more preferably 90°C to 150°C. The first die 100 may also be heated to a similar temperature. The pressing time is preferably approximately 1 second to 5 seconds. The above-mentioned pressing temperature and pressing time may be appropriately adjusted depending on the heat resistance of the substrate 3a and the adhesion temperature of the adhesive layer 3b. Under these conditions, the pulp mold 2A is compressed and deformed together with the label 3A, becoming harder and thinner with a smoother surface than before pressing. For example, a pulp mold 2A having a thickness of 0.8 mm to 3.0 mm or 1.5 mm to 2.5 mm before pressing will have a thickness of 0.8 mm to 1.5 mm after pressing.

[0068] Next, as shown in Figures 5 and 8, the pressing of the pulp mold 2A and the label 3A by the second die 110 is released (step S6). Specifically, as shown in Figure 8, the second die 110 retreats to the position before pressing (i.e., moves in the direction of arrow AR2 shown in Figure 8), thereby releasing the pressing of the pulp mold 2A and the label 3A by the second die 110. This completes the production of the labeled pulp mold 1A shown in Figures 1 to 3.

[0069] In the labeled pulp mold 1A according to the present embodiment described above, as mentioned above, the window portion 31a through which the storage space 20 can be viewed from the outside is provided in the covered area 31. This makes it possible to view the contents stored in the storage space 20 of the pulp mold 2A made of an opaque material from the outside through the window portion 31a while the upper container portion 21 remains closed.

[0070] Here, since the first portion X of the upper container portion 21 is a curved portion consisting of a curved surface that curves in multiple directions, if the label 3A is attached to the first portion X without any precautions, the label 3A will easily wrinkle or fold over.

[0071] In this regard, in the labeled pulp mold 1A according to the present embodiment, the label 3A is attached to the pulp mold 2A by pressing as described above, so that the portion of the label 3A corresponding to the first portion X is attached with a drawing rate of 10% to 50%. This allows the label 3A to be maintained in a shape that conforms to the surface of the pulp mold 2A, and prevents large wrinkles and folds from occurring in that portion. It also prevents any folds from overlapping. Furthermore, even if wrinkles or folds occur in the portion of the label 3A corresponding to the first portion X, these are absorbed by the thickness of the pulp mold 2A, so that it is possible to effectively prevent unevenness from occurring on the surface of the label 3A in that portion.

[0072] Therefore, by configuring in this way, the smoothness of the surface of the labeled pulp mold provided with the window can be significantly improved.

[0073] Furthermore, in the labeled pulp mold 1A according to this embodiment, as described above, the portion of the label 3A corresponding to the first portion X is designed to make wrinkles and folds in the label 3A less noticeable. This makes wrinkles and folds in the label 3A even less noticeable, improving the aesthetic appearance of the labeled pulp mold 1A and increasing the desire to purchase the product housed in the labeled pulp mold 1A.

[0074] Furthermore, in labeled pulp mold 1A according to this embodiment, as described above, label 3A is attached to pulp mold 2A with at least a portion in the thickness direction of covered region 31 of label 3A, which is the portion that covers hole 21a, fitting into hole 21a. This effectively prevents covered region 31 of label 3A from being damaged by contact with surrounding objects during transportation, display, etc. of labeled pulp mold 1A.

[0075] Furthermore, in the labeled pulp mold 1A according to this embodiment, as described above, the base material 3a of the label 3A is preferably made of a paper material, which reduces the environmental impact and costs compared to when a label made of a plastic film is used.

[0076] In the manufacturing method of labeled pulp mold 1A according to this embodiment, the shapes of first die 100 and second die 110 (see FIG. 7 and other figures) are not limited to those described above. For example, when first die 100 is viewed from above in step S5 (i.e., the pressing step using second die 110), the shape of first die 100 may be such that the surface of the portion of first convex portion 101 provided thereon that overlaps with hole 21a protrudes by the thickness of pulp mold 2A after compression. In this configuration, when label 3A is attached to pulp mold 2A in step S5, the first convex portion 101 corresponding to hole 21a abuts, via covered region 31, against the first concave portion 111 corresponding to hole 21a. This effectively prevents wrinkles and sagging in the portion of label 3A that defines window 31a.

[0077] Furthermore, the shape of the second mold 110 may be such that, when the second mold 110 is viewed from above in step S5, the surface of the portion of the first recessed portion 111 provided therein that overlaps with the hole 21a is recessed. In this configuration, when the label 3A is attached to the pulp mold 2A in step S5, the covered region 31 of the label 3A can be prevented from coming into contact with the heated second mold 110, thereby effectively preventing the portion of the label 3A that defines the window 31a from being deformed or damaged by heat.

[0078] (First Modification) Figure 9 is a cross-sectional view of a labeled pulp mold according to a first modified example, where Figure 9(A) is a cross-sectional view of the labeled pulp mold according to the first modified example of a portion corresponding to the cross-sectional view taken along line III-III in Figure 1, and Figure 9(B) is an enlarged cross-sectional view of a main portion near the hole in Figure 9(A). Below, a labeled pulp mold 1A1 according to the first modified example based on the above-mentioned embodiment 1 will be described with reference to Figure 9.

[0079] As shown in Figures 9(A) and 9(B), the labeled pulp mold 1A1 of the first modified example differs in configuration from the labeled pulp mold 1A of the above-mentioned embodiment 1 in that the label 3A1 further has a shielding layer 3c.

[0080] Specifically, in the labeled pulp mold 1A1 of the first modified example, the label 3A1 is attached to the outer surface of the upper container part 21, which is located on the opposite side of the storage space 20 when the upper container part 21 is closed, and a shielding layer 3c is provided on a portion of the main surface of the pair of main surfaces of the base material 3a of the label 3A1 that is not provided with the adhesive layer 3b, so as to cover the peripheral portion of the coated area 31.

[0081] The shielding layer 3c is preferably formed by solid printing using white, black, or other colored inks that have a shielding effect, but may also be formed by designs such as letters or pictures. The shielding layer 3c is formed by applying a printing ink of a desired color using a known printing method such as offset printing, flexographic printing, gravure printing, screen printing, or a plateless printing method such as inkjet printing. The shielding layer 3c may be formed by applying the printing ink once, or by applying it two or more times to enhance the shielding effect. Note that, because microscopically, unevenness occurs on the surface of the shielding layer 3c after the printing ink is applied, a coating layer such as a clear varnish or matte varnish may be further provided to cover the surface of the shielding layer 3c in order to smooth the surface, impart gloss, and improve the texture.

[0082] The thickness of the shielding layer 3c is not particularly limited, but is preferably, for example, about 0.5 μm to 10 μm, and more preferably, 1.5 μm to 5 μm.

[0083] In this configuration, the window portion 31a is provided in a portion other than the peripheral edge portion of the covered area 31. As a result, when the upper container portion 21 is closed and the storage space 20 is viewed from the outside, burrs and the like that may occur on the edge of the hole portion 21a during the production of the pulp mold 2A can be hidden by the shielding layer 3c.

[0084] Therefore, by using the labeled pulp mold 1A1 according to the first modified example, not only can the same effects as those described in the first embodiment be obtained, but the aesthetic appearance of the labeled pulp mold can also be improved.

[0085] In the labeled pulp mold 1A1 according to the first modified example described above, the shielding layer 3c is provided on a portion of one of the pair of main surfaces of the base material 3a of the label 3A3 on which the adhesive layer 3b is not provided, but the arrangement of the shielding layer 3c in the thickness direction of the label 3A is not particularly limited to this and may be arranged, for example, between the base material 3a and the adhesive layer 3b.

[0086] Furthermore, the position where the shielding layer 3c is provided is not limited to the peripheral portion of the covered area 31, but may also be provided as appropriate in portions of the covered area 31 other than the peripheral portion. Since the window portion 31a is provided in the portion of the covered area 31 where the shielding layer 3c is not provided, by providing the shielding layer 3c in a desired position as described above, it is possible to impart design features to the outline of the window portion 31a, thereby improving the aesthetic appearance of the labeled pulp mold 1A.

[0087] (Second Modification) Figure 10 is a cross-sectional view of a labeled pulp mold according to a second modified example, where Figure 10(A) is a cross-sectional view of the labeled pulp mold according to the second modified example of a portion corresponding to the cross-sectional view taken along line III-III in Figure 1, and Figure 10(B) is an enlarged cross-sectional view of a main portion near the hole in Figure 10(A). Below, a labeled pulp mold 1A2 according to the second modified example based on the above-mentioned first embodiment will be described with reference to Figure 10.

[0088] As shown in Figures 10(A) and 10(B), when compared with the labeled pulp mold 1A according to the first embodiment described above, the labeled pulp mold 1A2 according to the second modified example differs in the configuration of the base material 3a of the label 3A2 from that of the base material 3a of the label 3A described above.

[0089] Specifically, in the labeled pulp mold 1A2 of the second modified example, the base material 3a of the label 3A2 is so-called mesh-processed paper, which is a material in which multiple through holes are provided in a part of a non-light-transmitting paper as described above.

[0090] The meshed paper constituting the base material 3a is formed by applying an adhesive layer 3b to the base material 3a and then irradiating the base material 3a and adhesive layer 3b with a laser or the like to form holes. As a result, similar through holes are formed in the adhesive layer 3b in the areas corresponding to the through holes formed in the base material 3a. The holes are formed in the inner part of the coated area 31, excluding the peripheral edge.

[0091] As a result, in the labeled pulp mold 1A2, each of the multiple through holes provided in the covering area 31 of the label 3A2, which is the part that covers the hole portion 21a, forms a window portion 31a through which the storage space 20 can be seen from the outside.

[0092] When configured in this manner, not only can the same effects as those described in the above-mentioned embodiment 1 be obtained, but by changing the size and number of through holes provided in the base material 3a, it becomes possible to adjust the hiding power appropriately according to the functions required of the labeled pulp mold 1A2 as a product.

[0093] In the labeled pulp mold 1A2 according to this modification, the label 3A2 has the above-described perforations made only in a portion of the label 3A2, but the perforations may be made over the entire surface of the label 3A2. However, even in this case, the perforations do not need to be made in the portion of the label 3A2 on which a design is printed or the like.

[0094] (Third Modification) Figure 11 is a cross-sectional view of a labeled pulp mold according to a third modified example, where Figure 11(A) is a cross-sectional view of the labeled pulp mold according to the third modified example, corresponding to the cross-sectional view taken along line III-III in Figure 1, and Figure 11(B) is an enlarged cross-sectional view of a main part near the hole in Figure 11(A). Below, a labeled pulp mold 1A3 according to the third modified example based on the above-mentioned first embodiment will be described with reference to Figure 11.

[0095] As shown in Figures 11(A) and 11(B), the labeled pulp mold 1A3 of the third modified example differs in configuration from the labeled pulp mold 1A of the above-mentioned embodiment 1 in that the label 3A is attached to the inner surface of the upper container portion 21 of the pulp mold 2A (i.e., the surface facing the storage space 20 when the upper container portion 21 is closed).

[0096] Specifically, in the labeled pulp mold 1A3 of the third modified example, the label 3A is attached to the inner surface of the upper container portion 21 via an adhesive layer 3b so that when the upper container portion 21 is closed, the first main surface 3(1) of the label 3A defined by the base material 3a faces the storage space 20.

[0097] Even in this configuration, the same effects as those described in the first embodiment can be obtained.

[0098] (Fourth Modification) Fig. 12 is a plan view of a labeled pulp mold according to a fourth modified example in a state where the upper container portion is closed. Hereinafter, a labeled pulp mold 1A4 according to the fourth modified example based on the above-mentioned first embodiment will be described with reference to Fig. 12.

[0099] As shown in Figure 12, when compared with the labeled pulp mold 1A according to the first embodiment described above, the labeled pulp mold 1A4 according to the fourth modified example differs from the labeled pulp mold 2A described above in that the configuration of the hole portion 21a provided in the upper container portion 21 of the pulp mold 2A4 is different from that of the pulp mold 2A described above.

[0100] Specifically, in the labeled pulp mold 1A4 of the fourth modified example, the hole portion 21a is provided across a portion of the second part Y of the upper container part 21 that has an approximately flat shape and a curved portion consisting of a curved surface that is curved in one direction.

[0101] Even in this configuration, the same effects as those described in the first embodiment can be obtained.

[0102] (Fifth Modification) Fig. 13 is a plan view of a labeled pulp mold according to a fifth modified example with the upper container portion closed. Fig. 14 is a cross-sectional view of the labeled pulp mold shown in Fig. 13, Fig. 3(A) is a cross-sectional view of the labeled pulp mold according to the fifth modified example of a portion corresponding to the cross-sectional view taken along line III-III in Fig. 1, and Fig. 14(B) is an enlarged cross-sectional view of a main portion near the hole in Fig. 14(A). Below, a labeled pulp mold 1A5 according to a fifth modified example based on the above-mentioned first embodiment will be described with reference to Figs. 13 and 14.

[0103] As shown in Figures 13 and 14, when compared with the labeled pulp mold 1A according to the first embodiment described above, the labeled pulp mold 1A5 according to the fifth modified example differs from the labeled pulp mold 1A according to the first embodiment described above in that the configuration of the label 3A5 attached to the upper container portion 21 is different from that of the label 3A described above.

[0104] Specifically, in the labeled pulp mold 1A5 according to the fifth modification, the label 3A5 is attached only to a portion of the second portion Y of the upper container portion 21 that has a substantially planar shape, and the label 3A5 attached to a portion of the upper container portion 21 in this manner includes a covered region 31 that covers the hole 21a of the upper container portion 21. Also, as shown in Figures 14(A) and 14(B), the outer surface of the upper container portion 21 includes an attached surface 21(1), which is the portion to which the label 3A is attached, and an exposed surface 21(2), which is the portion to which the label 3A is not attached.

[0105] Here, at the boundary between the attached surface 21(1) and the exposed surface 21(2) of the pulp mold 2A, the attached surface 21(1) is positioned more recessed than the exposed surface 21(2). That is, when the upper container portion 21 is closed, the attached surface 21(1) is positioned closer to the storage space 20 than the exposed surface 21(2). As a result, a step portion 21b is provided in the upper container portion 21 of the pulp mold 2A, and the label 3A5 is attached to the pulp mold 2A with at least a portion of the label 3A5 in the thickness direction recessed into the step portion 21b. Such a configuration of the labeled pulp mold 1A5 is produced when the label 3A5 is pressed while stacked on the pulp mold 2A, as described above, and the label 3A5 is attached to the attached surface 21(1) of the pulp mold 2A while the attached surface 21(1) is compressed.

[0106] When configured in this manner, not only can the same effects as those described in the first embodiment be obtained, but the step portion 21b can absorb at least a portion of the thickness of the label 3A5, thereby significantly improving the smoothness of the surface of the labeled pulp mold 1A5.

[0107] (Verification test) In the verification test, several types of paper samples were prepared, and the hiding power of each sample was measured. The visibility of the contents when these samples were used as labels to cover the holes was also visually confirmed.

[0108] In this verification test, the paper samples were cellophane (Futamura Chemical Co., Ltd., ordinary cellophane PL #300), thin white glassine (Nippon Paper Industries Co., Ltd., glassine paper 25.8 g / m 2 ), extra-thick white glassine (Nippon Paper Industries glassine paper 40g / m 2 ), meshed paper (laser-processed paper manufactured by Kakukei Co., Ltd.), one-sided glossy paper (one-sided glossy bleached kraft paper manufactured by Nippon Paper Industries Co., Ltd., Capital Wrap 50g / m 2 ), one-sided glazed paper (Nippon Paper Industries Co., Ltd., one-sided glazed bleached kraft paper, Capital Wrap 80g / m 2 ), one-sided glazed paper (Nippon Paper Industries Co., Ltd., one-sided glazed bleached kraft paper, Capital Wrap 100g / m 2 ), one-sided glazed paper (Nippon Paper Industries Co., Ltd., one-sided glazed bleached kraft paper, Capital Wrap 120g / m 2 A total of eight samples of the above were prepared, and their hiding powers were measured using a spectrophotometer (product name: X-rite RM200QC portable color difference meter, manufactured by X-rite).

[0109] To measure the hiding power of the above samples, the sample was first placed on a reference black, and the tristimulus values ​​YB were measured using a spectrophotometer placed on the sample. Next, the sample was placed on a reference white, and the tristimulus values ​​YW were measured using a spectrophotometer placed on the sample. The hiding power of each sample was calculated by substituting the tristimulus values ​​YB and YW thus obtained into Equation 2 below. In this verification test, a thin black and white ledger (manufactured by Daimonji Paper Co., Ltd.) was used as the reference black and reference white.

[0110] (Formula 2) Opacity = (YB / YW) x 100 FIG. 15 is a table showing the hiding power of each sample measured by the method described above and the evaluation results of visibility when these were applied to the label 3A. The results of this verification test showed that when a member with a hiding power of 90% or less was used as the label 3A, the storage space 20 was visible from outside the labeled pulp mold 1A. When a member with a hiding power of 40% or less was used as the label 3A, the storage space 20 was clearly visible. In FIG. 14, samples in which the storage space 20 was clearly visible are marked "excellent," samples in which the storage space 20 was not clearly visible but was still visible are marked "good," and samples in which the storage space 20 was not clearly visible are marked "poor." A sample in which the storage space 20 was not clearly visible but was still visible is, for example, one in which the storage space 20 was visible when approached in a bright space.

[0111] The hiding power of mesh paper can be adjusted accordingly by changing the size and number of through holes formed in the paper. Therefore, by making the through holes larger than those formed in the mesh paper measured in this verification test or by increasing the number of through holes, the hiding power of the mesh paper can be made lower than the value shown in Figure 15. Therefore, by adjusting the number and size of the through holes formed in the mesh paper, the mesh paper can be used as a label that makes the contents visible from the outside.

[0112] (Embodiment 2) 16A and 16B are diagrams showing the shape and configuration of a labeled pulp mold according to a second embodiment, with Fig. 16A being a perspective view of the labeled pulp mold with the upper container portion half-opened, and Fig. 16B being a perspective view of the labeled pulp mold with the upper container portion fully opened. Fig. 17 is a plan view of the upper container portion of the labeled pulp mold shown in Fig. 16A. Hereinafter, a labeled pulp mold 1B according to this embodiment will be described with reference to Figs. 16A and 16B. When the labeled pulp mold 1B is used, the upper container portion 21 and the lower container portion 22 described below define the front and back sides of the labeled pulp mold 1B. However, for convenience of description, these will be referred to as the upper container portion 21 and the lower container portion 22, rather than as the front container portion and the back container portion.

[0113] As shown in Figures 16 and 17, the labeled pulp mold 1B of this embodiment differs from the labeled pulp mold 1A of embodiment 1 described above in that it can accommodate contents such as pouches with an approximately cylindrical outer shape and so-called standing pouches with a gusset on the bottom side, and has an upper container portion 21 and a lower container portion 22.

[0114] More specifically, the pulp mold 2B according to this embodiment includes an upper container portion 21, a lower container portion 22, a hinge portion 23, and a lid fastening portion 24. The lid fastening portions 24 are provided at the axial end of the upper container portion 21 that is not connected to the hinge portion 23, and at the axial end of the lower container portion 22 that is not connected to the hinge portion 23. The pulp mold 2B is configured so that the lid can be kept closed by engaging the lid fastening portions 24 with the spout of a pouch contained therein. The lower container portion 22 also has a recess 22a that is curved so as to face the upper container portion 21 when the upper container portion 21 is closed. The recess 22a, together with the upper container portion 21, defines a storage space 20 in which a pouch serving as a content is stored when the upper container portion 21 is closed.

[0115] The upper container portion 21 of the pulp mold 2B has a generally flat central portion in a plan view and a concave portion curved so that its peripheral edge faces the storage space 20. As shown in Fig. 16, first portions X, which are curved portions consisting of curved surfaces curved in multiple directions, are located at two of the four corners of the peripheral edge that are located on the lid fastening portion 24 side and at a portion of the peripheral edge that is adjacent to the hinge portion 23 side.

[0116] In the labeled pulp mold 1B according to this embodiment, the label 3B is attached to the entire surface of the upper container portion 21, including the first portion X and the second portion Y, which is the remaining portion.

[0117] Here, the portion of label 3B corresponding to first portion X is attached to the first portion X with a squeeze rate of 10% or more and 50% or less, and the portion of label 3B corresponding to second portion Y is attached to the second portion Y with a squeeze rate of less than 10%.

[0118] The second part Y of the upper container part 21 has an approximately rectangular hole 21a that extends in the width direction of the upper container part 21 when viewed in a plane, and a label 3B is attached to the upper container part 21 so as to cover the hole 21a.

[0119] As a result, the covering area 31 of the label 3B, which is the part that covers the hole 21a, is provided with a window portion 31a that allows the storage space 20 to be seen from the outside, and if the pouch contained in the storage space 20 is made of a transparent material, the beverage, cosmetics, etc. filled in the pouch can also be seen through the window portion 31a.

[0120] Here, the method for manufacturing the labeled pulp mold 1B according to this embodiment involves steps similar to those for manufacturing the labeled pulp mold 1A according to the first embodiment described above.

[0121] Even when configured in this manner, the same effects as those described in the above-mentioned embodiment 1 can be obtained, and the surface smoothness of a labeled pulp mold with a window portion can be greatly improved.

[0122] In the labeled pulp mold 1B of this embodiment, as described above, the second part Y of the upper container part 21 has an approximately rectangular hole 21a that extends in the width direction of the upper container part 21 when viewed in a plane.However, if the shape of the hole 21a is made approximately rectangular extending in a direction perpendicular to the width direction of the upper container part 21 (i.e., the up-and-down direction in Figure 17), the remaining amount of content in the pouch, etc. can be visually confirmed through the window part 31a provided corresponding to the hole 21a.

[0123] (Other forms, etc.) In the above-described embodiments and their variations, the configuration of a labeled pulp mold in which one window portion is provided has been described as an example, but the number of window portions is not particularly limited to this, and multiple window portions may be provided.

[0124] In the above-described embodiment and its modified examples, the configuration of the labeled pulp mold in which the upper and lower container parts are connected by a hinge part has been described as an example, but the upper and lower container parts may be formed as separate members without being connected by a hinge part. In this case, the upper and lower container parts may be attached to each other, for example, via a fitting part formed on each part, and the window part described above may be provided in either the upper or lower container part.

[0125] Furthermore, in the above-mentioned embodiment and its variants, the present invention has been described as being applied to a labeled pulp mold configured to be able to contain foundation, puffs, and pouches as contents, but the present invention can naturally also be applied to labeled pulp molds configured to be able to contain various products other than the above-mentioned foundation as contents.

[0126] Furthermore, in the above-described embodiments and their variations, the present invention has been described as being applied to a labeled pulp mold as a container configured to contain contents, but the present invention can naturally also be applied to labeled pulp molds as lid materials for containers, covers for various items, etc.

[0127] The shape, configuration, size, number, material, etc. of each part shown in the above-described embodiment of the present invention and its modified examples can be changed in various ways without departing from the spirit of the present invention.

[0128] Furthermore, the characteristic configurations shown in the above-described embodiments of the present invention and their modifications can naturally be combined with each other within the scope of the present invention.
