[0009] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention relates to a container having a label attached thereto. Several embodiments will be described in detail below.

[0011] <First embodiment> (composition) 1 is an explanatory diagram showing the appearance of a container 1 according to a first embodiment of the present invention. As shown in FIG. 1, the container 1 according to the first embodiment includes a container body 10 and a cap 20.

[0012] The container body 10 has a body 110, a bottom 120, a neck 130, and a handle 140. The body 110 has a tubular shape. The body 110 may have, for example, a substantially rectangular tubular shape consisting of a front, a back, and a side as shown in FIG. 1, or may have a cylindrical shape. The bottom 120 is a portion that contacts the placement surface when the container 1 is placed on the placement surface. The bottom 120 closes an opening on one side formed by the body 110. A storage space for the contents is formed inside the body 110 and the bottom 120. The neck 130 is a tubular portion that is connected to the storage space.

[0013] The contents may be liquid or solid. Examples of liquids include liquids, gels, and pastes. Liquids, gels, and pastes all have fluidity in common, but liquids do not have a fixed shape, while gels and pastes are semi-solid and may temporarily have a fixed shape. Examples of solids include granular, granular, and powdery objects. Specifically, the contents stored in the storage space of the container body 10 may be liquid detergent, fabric softener, bleach, shampoo, rinse, conditioner, body soap, cosmetic liquid, hair dye, medicine, liquid seasoning, etc.

[0014] The handle portion 140 is connected to the body portion 110, and forms a hole between the handle portion 140 and the body portion 110. A user can easily use the container 1 by passing a finger through the hole and gripping the handle portion 140. Note that, not limited to this embodiment, the container body 10 does not necessarily have to have the handle portion 140.

[0015] Such a container body 10 may be made of synthetic resin, such as polyolefins, such as polyethylene (PE), polypropylene (PP), and polybutene, polyesters, such as polyethylene terephthalate (PET), polyamides, polyvinyl chloride, polystyrene, and polylactic acid.

[0016] The cap 20 is removably attached to the neck portion 130. For example, the inner circumferential surface of the cap 20 and the outer circumferential surface of the neck portion 130 are screwed together, thereby removably attaching the cap 20 to the neck portion 130. When the cap 20 is attached to the neck portion 130, the opening of the neck portion 130 that is connected to the storage space of the container body 10 is closed, and when the cap 20 is removed from the neck portion 130, the opening of the neck portion 130 is opened.

[0017] Furthermore, the container 1 according to the first embodiment has a label 40. The label 40 is attached to the outer peripheral surface of the body 110 as shown in FIG. 1. The label 40 has a base layer on which a product name, product description, etc. are printed, and an adhesive layer that bonds the base layer to the body 110. The adhesive layer may be made of cold glue or hot melt glue. A non-flat portion 31 is formed on a part of the outer peripheral surface of the body 110 to which the label 40 is attached, as shown in FIG. 1. The non-flat portion 31 will be described below with reference to FIG. 2.

[0018] Fig. 2 is an explanatory diagram showing the container 1 in a state where the label 40 is not attached. In Fig. 2, an attachment area 60 where the label 40 is attached is indicated by a dashed line. The attachment area 60 is a partial area of ​​the outer peripheral surface of the body portion 110, and the outer peripheral surface of the body portion 110 is an example of a surface portion that includes the attachment area 60.

[0019] A recess or a protrusion is formed in the non-flat portion 31. When the portion of the non-flat portion 31 that protrudes most outward in the thickness direction of the body portion 110 is taken as a reference, it can be said that a recess is formed in the non-flat portion 31, and when the portion of the non-flat portion 31 that is recessed most inward in the thickness direction of the body portion 110 is taken as a reference, it can be said that a protrusion is formed in the non-flat portion 31. In the following, the explanation will be continued from the viewpoint that a recess is formed in the non-flat portion 31 as an example.

[0020] In the non-flat portion 31, a plurality of dot-shaped recesses may be formed, a plurality of linear recesses may be formed, or a mixture of dot-shaped recesses and linear recesses may be formed. The dot-shaped recesses may be circular, angular, or of another shape in a front view. The linear recesses may be recesses having a straight line shape, a zigzag shape, or a curved shape in a front view.

[0021] The non-flat portion 31 and the attachment area 60 overlap. In the example shown in Fig. 2, the entire attachment area 60 overlaps the non-flat portion 31. The non-flat portion 31 is also formed in a range surrounding the attachment area 60, i.e., a range outside the attachment area 60 and adjacent to the attachment area 60. This range is a range that is visible even after the label 40 is attached, as shown in Fig. 1. From another perspective, the non-flat portion 31 and the attachment area 60 have similar shapes, and the similarity ratio of the non-flat portion 31 to the attachment area 60 is limited to within a certain value (for example, within 1.05).

[0022] The method for manufacturing the container body 10 having the non-flat portion 31 is not particularly limited. For example, the method for manufacturing the container body 10 includes blow molding such as injection blow or direct blow. It is possible to manufacture the container body 10 having the non-flat portion 31 by providing irregularities in a mold used for blow molding. Alternatively, it is also possible to form the non-flat portion 31 by subjecting the container body 10 to processing such as sanding and shot peening after molding the container body 10. Furthermore, when a separate member having irregularities is bonded to the container body 10 after molding the container body 10, the separate member becomes the non-flat portion 31.

[0023] (Action and effect) According to the first embodiment of the present invention described above, various effects can be obtained. For example, in the container 1 according to the first embodiment of the present invention, the non-flat portion 31 is formed so as to overlap with the attachment area 60. In the portion where the attachment area 60 and the non-flat portion 31 overlap, the label 40 and the recess are not adhered to each other, or the adhesion between the label 40 and the recess is weakened. Therefore, the adhesive strength between the label 40 and the body portion 110 is lower than when the label 40 is attached to a flat surface. Therefore, the user of the container 1 or the company that collects the container 1 can easily peel off the label 40 from the body portion 110. That is, according to the first embodiment of the present invention, it is possible to provide a container 1 with improved recyclability.

[0024] Furthermore, according to the first embodiment of the present invention, the entire attachment area 60 overlaps the non-flat portion 31. With this configuration, the label 40 can be easily peeled off from the body portion 110 from any part of the outer edge of the label 40.

[0025] Furthermore, according to the first embodiment of the present invention, the non-flat portion 31 is formed only on a part of the outer circumferential surface of the body portion 110. More specifically, the similarity ratio of the non-flat portion 31 to the attachment area 60 is limited within a certain value. Therefore, compared to a case where the non-flat portion 31 is formed over a wider range, this has superior cosmetic appearance.

[0026] <Second embodiment> Next, a second embodiment of the present invention will be described. In the second embodiment of the present invention, a non-flat portion 32 is formed that overlaps only a portion of the attachment area 60. Hereinafter, the configuration of the container 2 according to the second embodiment of the present invention will be described with reference to Figs. 3 and 4.

[0027] (composition) Fig. 3 is an explanatory diagram showing the appearance of a container 2 according to a second embodiment of the present invention. Fig. 4 is an explanatory diagram showing the container 2 in a state in which a label 40 is not attached. As shown in Figs. 3 and 4, in the second embodiment of the present invention, the non-flat portion 32 of the container body 12 is formed so as to overlap only with the area of ​​the attachment area 60 on the bottom 120 side of the container 2.

[0028] More specifically, the attachment area 60 has a plurality of edges along a direction intersecting the height direction of the container 2, and the plurality of edges includes an edge 67 located on the bottom 120 side of the container 2. The non-flat portion 32 is formed along the edge 67 so as to overlap the entire edge 67.

[0029] Furthermore, label 40 is formed with an indication indicating the position of non-flat portion 32. In the example shown in Fig. 3, label 40 is formed with indication 46, as an indication indicating the position of non-flat portion 32, which includes an arrow pointing to edge 47 on the bottom 120 side and text indicating that label 40 is easy to peel off from edge 47 on the bottom 120 side.

[0030] (Action and effect) According to the second embodiment of the present invention described above, various effects can be obtained. For example, according to the second embodiment of the present invention, the non-flat portion 32 is formed, which overlaps only a part of the attachment area 60. With this configuration, it is possible to improve the aesthetics of the container 2 while ensuring the adhesiveness of the label 40. For example, the ratio of the area where the attachment area 60 and the non-flat portion 32 overlap with respect to the area of ​​the attachment area 60 may be 5% or more, more preferably 10% or more, from the viewpoint of ensuring the adhesive strength of the label 40. Moreover, the ratio of the area where the attachment area 60 and the non-flat portion 32 overlap with respect to the area of ​​the attachment area 60 may be 50% or less, more preferably 25% or less, from the viewpoint of the aesthetics of the container 2 and the ease of peeling off the label 40.

[0031] Furthermore, according to the second embodiment of the present invention, the non-flat portion 32 is formed to overlap the area of ​​the attachment area 60 on the bottom 120 side of the container 2. With this configuration, dust and contents dripping from the neck portion 130 are less likely to get between the label 40 and the body portion 110, so that the adhesive strength of the label 40 can be prevented from being excessively weakened.

[0032] Furthermore, according to the second embodiment of the present invention, the label 40 is formed with an indication 46 that indicates the position of the non-flat portion 32. With this configuration, a user or a business that collects the container 2 can easily peel off the label 40 from the edge 47 on the bottom 120 side by following the indication 46.

[0033] <Third embodiment> Next, a third embodiment of the present invention will be described. In the third embodiment of the present invention, a non-flat portion 33 is formed that overlaps less with a part of the attachment region 60. Hereinafter, the configuration of a container 3 according to the third embodiment of the present invention will be described with reference to FIG.

[0034] (composition) Fig. 5 is an explanatory diagram showing the container 3 in a state where the label 40 is not attached. As shown in Fig. 5, the non-flat portion 33 of the container body 13 is formed so as to overlap a part of the edge 67 on the bottom 120 side of the attachment area 60, but not overlap other parts of the edge 67. In the example shown in Fig. 5, the non-flat portion 33 overlaps one end of the edge 67, and the non-flat portion 33 does not overlap the other end of the edge 67.

[0035] (Action and effect) Generally, a label is peeled off by peeling off an edge of the label with a fingernail or the like, and then holding the edge with fingers and pulling off the label. Of these, peeling off the edge of the label is the most stressful. In this regard, according to the third embodiment of the present invention, the non-flat portion 33 overlaps one end of the edge 67, so that it is possible to improve the aesthetic appeal of the container 3 while ensuring ease of peeling off the label 40 from the overlapping portion.

[0036] <Fourth embodiment> Next, a fourth embodiment of the present invention will be described. In the fourth embodiment of the present invention, a label 44 having a fragile portion formed therein is used. Hereinafter, the configuration of a container 4 according to the fourth embodiment of the present invention will be described with reference to Figs. 6 and 7.

[0037] (composition) Fig. 6 is an explanatory diagram showing the appearance of a container 4 according to a fourth embodiment of the present invention. Fig. 7 is an explanatory diagram showing a container 4 in a state in which a label 44 is not attached. A fragile portion 48 is formed in a part of the label 44 according to the fourth embodiment of the present invention. As shown in Fig. 6, the fragile portion 48 may be a perforation. However, the fragile portion 48 may be any portion that is more easily torn than other portions of the label 44, and may be, for example, a portion that is formed thinner than other portions of the label 44.

[0038] The non-flat portion 34 of the container body 14 according to the fourth embodiment of the present invention is formed at a position overlapping with the weakened portion 48. Since the weakened portion 48 is formed in a portion away from the edge of the label 44 as shown in Fig. 6, the non-flat portion 34 is formed inside the attachment area 60, and is not formed at a position adjacent to the attachment area 60 on the outside of the attachment area 60 as shown in Fig. 7.

[0039] Furthermore, label 44 is formed with an indication indicating the position of non-flat portion 34. In the example shown in Fig. 6, label 44 is formed with an indication 49 indicating the position of non-flat portion 34, which includes an arrow pointing to fragile portion 48 and text instructing the user to tear fragile portion 48 before peeling off label 44.

[0040] (Action and effect) According to the fourth embodiment of the present invention described above, various actions and effects can be obtained. For example, in the fourth embodiment of the present invention, the non-flat portion 34 is formed at a position overlapping the fragile portion 48. That is, the adhesive strength between the label 44 and the body portion 110 is weakened at the fragile portion 48. Therefore, a user or a business that collects the container 4 can easily peel off the label 44 from the edge of the fragile portion 48 after tearing the label 44 at the fragile portion 48.

[0041] 7, the non-flat portion 34 is formed inside the attachment area 60, and is not formed outside the attachment area 60 at a position adjacent to the attachment area 60. In other words, the non-flat portion 34 is not directly visible when the label 44 is attached, and therefore the aesthetic appeal of the container 4 can be improved.

[0042] Furthermore, according to the fourth embodiment of the present invention, an indication 49 is formed on the label 44 to indicate the position of the non-flat portion 34. With this configuration, a user or a business that collects the container 2 can follow the indication 49 to break the fragile portion 48 and then easily peel off the label 44.

[0043] <Supplementary Information> Although the preferred embodiment of the present invention has been described in detail above with reference to the attached drawings, the technical scope of the present invention is not limited to such examples. It is clear that a person having ordinary knowledge in the technical field of the present invention can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0044] For example, the following design may be applied to the recesses or protrusions formed in the non-flat portions 31 to 34 (hereinafter collectively referred to as non-flat portion 30) according to the above-described embodiment.

[0045] The shape of the recessed or protruding portion may be, for example, a point (circle), a line, or a curve. Such a shape has the effect of making it easier to peel off the label 40 from the container 1, etc. The shape of the recessed or protruding portion is not limited to the above-mentioned shapes, and other shapes can be applied as long as they are within the range in which the effects of the present invention are achieved.

[0046] The height difference between the most outwardly protruding portion of the non-flat portion 30 and the most inwardly recessed portion of the non-flat portion 30 may be, for example, 0.3 mm or more and 5.0 mm or less. More preferably, the height difference may be 0.8 mm or more and 2.0 mm or less. By making the height difference 0.3 mm or more, an effect of partial adhesion of only the non-flat portion 30 can be obtained, and by making the height difference 5.0 mm or less, cosmetic properties can be obtained.

[0047] The distance between the tops of adjacent protrusions may be 1 mm or more and 10 mm or less. More preferably, the distance may be 2 mm or more and 5 mm or less. By making the distance 1 mm or more, the adhesion area of ​​the label 40 to the protrusions can be reduced, and the effect of making it easier to peel the label 40 from the container 1, etc. can be obtained, and by making the distance 10 mm or less, the effect of making the label 40 adhere evenly without sinking between the protrusions can be obtained.
