Description

[Technical field]

[0001] The present invention relates to a container for food, drink, etc. that is to be stored in a cool place, and in particular to a container with a label that can suppress the formation of condensation on the outer surface of the container. [Background technology]

[0002] Summer in Japan is hot and humid, so for example beverages that are sold cooled to around 5°C in vending machines or in stores quickly reach their dew point in summer, causing problems such as water droplets forming on the outside of the container, wetting the bottom of the container, getting your fingers wet when holding the container, and getting your belongings wet when storing the container in a bag, etc.

[0003] In response to this, Patent Document 1 discloses that the occurrence of condensation is suppressed by providing a heat-shrinkable label having a foamed resin layer so as to wrap the body of the container. However, the label in Patent Document 1 cannot sufficiently suppress the occurrence of condensation, and there is room for further improvement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2001-125489 A Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, an object of the present invention is to provide a labeled container that can suppress condensation on the outer surface of the container. [Means for solving the problem]

[0006] The labeled container of the present invention, developed to achieve the above-mentioned objective, is a labeled container having a label attached to the outer surface of the body of a container body, wherein the label is made of a porous material that allows moisture to pass through, and a water-soluble resin layer is provided between the outer surface of the body of the container body and the label, which is capable of absorbing moisture that has permeated through the label and is in direct contact with the label or indirectly via an adhesive layer.

[0007] In addition, in the labeled container of the present invention, it is preferable that the water-soluble resin layer consists of at least one selected from water-soluble polyester resin, water-soluble polyamide resin, water-soluble polyimide resin, water-soluble acrylic resin, water-soluble polyurethane resin, water-soluble polyallylamine resin, water-soluble phenol resin, water-soluble epoxy resin, water-soluble phenoxy resin, water-soluble urea resin, water-soluble melamine resin and polyvinyl alcohol resin.

[0008] In the labeled container of the present invention, the porous material is preferably made of a nonwoven fabric, pulp or a foam sheet.

[0009] In the labeled container of the present invention, it is preferable that the water-soluble resin layer is provided in a recess formed on the outer surface of the barrel of the container body.

[0010] Furthermore, in the labeled container of the present invention, it is preferable that the label has a covering area such that at least the water-soluble resin layer is not exposed from the end face of the label. Effect of the Invention

[0011] According to the labeled container of the present invention, a water-soluble resin layer is provided on the outer surface of the barrel of the container body, and a label is attached so as to cover this water-soluble resin layer. This allows water droplets that form on the barrel of the container body due to condensation to be absorbed by the water-soluble resin layer. Therefore, even if a container that has been cooled and stored in a refrigerator or the like is taken out into a room temperature environment, condensation will not form on the surface of the label, and hands will not get wet, and water droplets will not splash or drip.

[0012] Furthermore, in the labeled container of the present invention, the label is made of a porous material such as nonwoven fabric, so that hands and fingers can be protected from the sticky water-soluble resin that absorbs water droplets, eliminating any discomfort.

[0013] In addition, the water-soluble resin layer can be easily dissolved in a washing process, so the recyclability of the container is not hindered. Furthermore, since the water-soluble resin layer absorbs condensed water droplets, clouding due to condensation does not occur, and the transparency of the container can be maintained.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows one embodiment of a labeled container according to the present invention, where (a) is a plan view, (b) is a front view, and (c) is a cross-sectional view taken along the line AA in (a). Fig. 2 shows a schematic cross-section of a label, where (a) shows a case where an adhesive layer is provided on the entire surface of a porous layer, and (b) and (c) show a case where an adhesive layer is provided on a portion surrounding a water-soluble resin layer. Fig. 3 is a cross-sectional view showing another embodiment of a labeled container according to the present invention.

[0016] Reference numeral 1 in the drawing denotes a bottomed, cylindrical container body that contains the contents. In this embodiment, a cylindrical deep-drawn cup is shown as an example of the container body 1, but the shape of the container body 1 can be appropriately changed based on the type of contents, the design of the container, the purpose, etc. The container body 1 is made of synthetic resin, glass, metal, etc., and the material is not particularly limited, and a plastic bottle, a pouch container, etc. can also be used.

[0017] The container body 1 is composed of a body 11 which forms a filling space for the contents inside, a flange 12 which extends outward from the top of the body 11, a bottom wall 13 which is connected to the lower end of the body 11, and a cylindrical leg 14 which is suspended from the bottom wall 13.

[0018] Reference numeral 2 denotes a label provided so as to surround the outer surface of the body 11 of the container body 1. Specifically, the label 2 uses a porous layer 23 that is permeable to moisture, and between the porous layer 23 and the body 11, as shown in Fig. 1(c), a water-soluble resin layer 21 that contacts the outer surface of the body 11 and an adhesive layer 22 located on the outside of the water-soluble resin layer 21 are provided. Note that when a shrink label that can be attached to the container body 1 by utilizing heat shrinkage is used as the label 2, the adhesive layer 22 can be omitted.

[0019] The water-soluble resin layer 21 can be made of various materials as long as they do not affect the deterioration of the processability and the substrate, but is preferably made of at least one selected from water-soluble polyester resin, water-soluble polyamide resin, water-soluble polyimide resin, water-soluble acrylic resin, water-soluble polyurethane resin, water-soluble polyallylamine resin, water-soluble phenol resin, water-soluble epoxy resin, water-soluble phenoxy resin, water-soluble urea resin, water-soluble melamine resin, and polyvinyl alcohol resin, and may also be made of a blend of multiple resins or a laminate. The thickness of the aqueous solution resin layer 21 is not particularly limited, but for example, when polyvinyl alcohol resin is used, the thickness of the aqueous solution resin layer 21 is 1 cm2, and .... 2It is preferable that the water-soluble resin is applied in the range of about 4.0 to 7.0 mg (preferably 5.5 mg or more) per unit area, and this reduces the absolute humidity to about 40 g / m 2 Therefore, for example, when the container of this embodiment is taken out of a refrigerator, condensation occurs on the outer surface of the trunk part 11 of the container body 1 due to the temperature difference between the inside and the outside, but the adhering water droplets can be quickly absorbed by the water-soluble resin layer 21.

[0020] The adhesive layer 22 is used to attach the porous layer 23 to the trunk portion 11 of the container body 1. The adhesive layer 22 may be a conventionally known adhesive that does not prevent moisture permeation, such as a heat-sensitive adhesive or a pressure-sensitive adhesive. The adhesive layer 22 may be provided on the entire surface of the porous layer 23 as shown in Fig. 2(a), or may be provided only on the outer periphery of the porous layer 23 so as to surround the water-soluble resin layer 21 as shown in Fig. 2(b) and Fig. 2(c).

[0021] The porous layer 23 is made of a porous material so that water droplets adhering to the surface due to condensation can pass through quickly and be absorbed by the water-soluble resin layer 21 located inside. The porous layer 23 is preferably made of a nonwoven fabric, pulp, or a foamed sheet. The nonwoven fabric can be, but is not limited to, synthetic fibers such as polyester or polyolefin, or semi-synthetic fibers, or natural fibers in a sheet shape. The pulp can be, but is not limited to, Japanese paper, or the like. The foamed sheet can be, but is not limited to, a foamed polyethylene sheet, a foamed polypropylene sheet, a foamed polystyrene sheet, or the like. In addition, a printed layer such as gravure-printed polypropylene may be provided on the surface of the porous layer 23, which can give the label 2 a design and reinforce the label 2.

[0022] The porous layer 23 is made larger in size than the water-soluble resin layer 21 and is provided so as to cover the entire water-soluble resin layer 21. This prevents the water-soluble resin layer 21 from being exposed at the edge faces of the label 2, and makes it possible to prevent the water-soluble resin layer 21 from becoming sticky.

[0023] When the container of this embodiment is cooled, for example, in a refrigerator and then removed, condensation forms on the outer surface of the label 2 (porous layer 23) due to the temperature difference between the inside and outside. However, the adhering water droplets pass through the porous layer 23 and are quickly absorbed by the water-soluble resin layer 21 located on the inside, so that the water droplets do not remain attached to the surface of the label 2, and the hands and fingers do not get wet, and the water droplets do not splash or drip.

[0024] Next, a method for attaching the label 2 to the body 11 of the container 1 will be described. Below, a case where the water-soluble resin layer 21 is made of polyvinyl alcohol will be described as a representative example.

[0025] <First installation method> In this method, the label 2 can be provided on the outer surface of the body 11 after the container body 1 is molded. First, a polyvinyl alcohol solution adjusted to 5 to 10 vol % is applied to the outer surface of the barrel 11 of the container body 1 and dried at or below the heat distortion temperature to coat the outer surface of the barrel 11 of the container body 1 with a water-soluble resin layer 21. Next, for example, a label 2 (porous layer 23) made of nonwoven fabric is prepared by coating an adhesive layer 22, and this is attached to the outer surface of the body 11 so as to cover the entire water-soluble resin layer 21. In this way, the label 2 can be provided so as to surround the body 11 of the container body 1.

[0026] In the first method, as shown in Fig. 3, a recess 15 is provided along the outer peripheral surface of the trunk 11 of the container body 1, and after the water-soluble resin layer 21 is coated in the recess 15, the entire recess 15 is covered with the label 2 (porous layer 23) to which the adhesive layer 22 is applied. The label 2 can be a shrink label, a tack label, a roll label, or the like, and the type is not limited. In this case, since the water-soluble resin layer 21 is provided in the recess 15, the water-soluble resin layer 21 is not exposed from the end face of the label 2, and the occurrence of stickiness due to the water-soluble resin layer 21 can be prevented.

[0027] Furthermore, in the first method, the water-soluble resin layer 21 may be coated on the outer surface of the barrel 11 of the container body 1, and then an adhesive layer 22 may be applied to the surface of the water-soluble resin layer 21 and its outer periphery, or to the area surrounding the water-soluble resin layer 21, and the label 2 (porous layer 23) may be attached to the adhesive layer 22.

[0028] Furthermore, in the first method, the adhesive layer 22 and the water-soluble resin layer 21 may be arranged on the surface of the label 2 (porous layer 23) by coating or the like, for example, in a state as shown in Figures 2(a) to (c), and then this may be attached to the trunk 11 of the container body 1.

[0029] <Second installation method> In this method, the label 2 can be provided so as to surround the outer surface of the barrel 11 at the same time as the container body 1 is molded. First, the adhesive layer 22 and the water-soluble resin layer 21 are laminated on the surface of the label 2 (porous layer 23) by coating or the like, and then the resultant is set in a mold and injection molding is performed, thereby attaching the label 2 to the container body 1 at the same time as molding the container body 1, a process known as in-mold molding. [Industrial Applicability]

[0030] The labeled container of the present invention can be suitably used as a container for storing contents that are to be stored in a refrigerated state, such as beverages, jellies, and other foods and beverages, or medicines. [Explanation of symbols]
