Description

The present invention relates to a label affixing structure having a recess into which a label is inserted and affixed.

Conventionally, on the surface of a member (hereinafter, simply referred to as "appearance member") that appears on the appearance of a product, a sheet-like member (hereinafter, simply "label") such as a label or a seal on which information related to this product is described is described. ) Is pasted. When this label is attached to the surface of the exterior member, it protrudes from the surface of the exterior member by the thickness thereof and is easily peeled off. Therefore, for example, as described in Patent Document 1, a label affixing structure that makes it difficult for the label to come off has been proposed.

The label affixing structure disclosed in Patent Document 1 has a structure in which a label is affixed to a recess formed on the surface of a disc-shaped recording medium such as a CD or DVD. The recess is formed by recessing the portion of the surface of the disc-shaped recording medium to which the label is attached from the other portion. The label is affixed to the flat bottom of this recess. By making the depth of the recesses deeper than the thickness of the label, the label does not protrude from the disc-shaped recording medium, and the label is less likely to be peeled off. Further, since the label sticking position can be determined by bringing the edge of the label into contact with the side wall of the recess when the label is stuck, the work of aligning the label sticking position becomes easy.

The conventional label affixing structure including the affixing structure described in Patent Document 1 is configured by using the recess 1 as shown in FIG. The recess 1 shown in FIG. 6 is connected to an opening 3 formed on the outer surface of the exterior member 2, a side wall 4 extending from the opening 3 toward the inside of the product with the opening 3 as one end, and the other end of the side wall 4. It is formed by a bottom wall 5 extending in a direction intersecting the side wall 4. The appearance member 2 is formed of a synthetic resin material and is formed into a predetermined shape including the recess 1 using a mold (not shown).

The portion serving as the boundary between the side wall 4 of the recess 1 and the bottom wall 5 is formed by a rounded portion 6 formed of a concave curved surface. The rounded portion 6 is a transfer of the rounded corner portion of the mold. The rounded portion 6 shown in FIG. 6 is drawn larger than it actually is so that the shape can be easily understood. There are two main reasons why the rounded portion 6 is provided in this way. The first reason is to prevent the boundary portion between the side wall 4 of the recess 1 and the bottom wall 5 from being damaged by stress concentration. The second reason is that the sharp corners are rounded in order to increase the durability of the mold.

Japanese Unexamined Patent Publication No. 2008-71446

When a rounded portion 6 having a concave curved surface is provided at the boundary portion between the side wall 4 of the recess 1 and the bottom wall 5 as shown in FIG. 6, the rounded portion 6 is labeled as shown in FIGS. 7 and 8. Problems arise when the ends 7a of 7 overlap. That is, as shown in FIG. 7, when the label 7 is attached to the rounded portion 6, the end portion 7a of the label 7 bends along the rounded portion 6 and internal stress is generated in the direction of returning to the initial flat state.

When time elapses in this state and the adhesive force of the adhesive (not shown) for attaching the label 7 to the rounded portion 6 becomes weak, the end portion of the label 7 where the internal stress is generated as described above becomes the rounded portion 6. By pressing, it will be peeled off from the rounded portion 6. This phenomenon is remarkable when the label 7 is thick.
Further, when one end of the label 7 is applied to the side wall 4 of the recess 1 for attaching the label 7, the rounded portion 6 may serve as a guide for guiding one end of the label 7 to the outside of the recess 1. There was also a problem that it was difficult to determine the position.

Further, as shown in FIG. 8, when the label 7 has a relatively high rigidity and the label 7 cannot be easily bent, the end portion 7a of the label 7 rides on the rounded portion 6 and the label 7 is tilted. In this state, the adhesive surface between the label 7 and the bottom wall 5 of the recess 1 cannot be secured.

An object of the present invention is to provide a label affixing structure in which a label is reliably affixed to the bottom wall of a recess despite the rounded portion being formed in the recess.

In order to achieve this object, the label affixing structure according to the present invention has an opening formed in a shape capable of inserting the label on the surface of a member to which the label is affixed, and the member from the opening with the opening as one end. The bottom wall is provided with a recess for labeling formed by a side wall extending inward and a bottom wall connected to the other end of the side wall and extending in a direction intersecting the side wall, and the bottom wall is connected to the side wall. It has a groove formed at the boundary portion and a label-attached surface extending from the groove wall facing the side wall in the groove to the side opposite to the side wall.

In the present invention, in the label affixing structure, at least a part of the label affixed to the label affixing surface protrudes from the label affixing surface toward the groove side and is predetermined between the label affixing surface and the side wall when viewed from the opening side. It may overlap with the groove in a state where a gap is formed.

In the present invention, in the label affixing structure, the depth of the groove is such that a rounded portion formed by molding at the boundary between the bottom of the groove and the side wall is accommodated in the groove. There may be.

In the label sticking structure according to the present invention, the label can be stuck so that the end portion of the label overlaps with the groove when viewed from the opening side of the recess. The end of this label protrudes from the bottom wall of the recess toward the opening side of the groove. A rounded portion is formed at the boundary between the side wall of the recess and the bottom of the groove as in the conventional case. This rounded portion is located on the back side of the label by the depth of the groove as compared with the conventional case.

For this reason, the end portion of the label is in a state of being stretched without bending without contacting the rounded portion, or is in a state of only contacting a portion having a small amount of protrusion with respect to the side wall, which is the starting point of the rounded portion. .. As a result, the label is surely attached to the bottom wall of the recess. Such a sticking state is the same even when the rigidity of the label is high.
Therefore, according to the present invention, it is possible to provide a label sticking structure in which the label is surely stuck to the bottom wall of the recess even though the rounded portion is formed in the recess.

Hereinafter, an embodiment of the label affixing structure according to the present invention will be described in detail with reference to FIGS. 1 to 5.
The label affixing structure 11 shown in FIG. 1 includes a concave portion 13 for affixing a label that opens on the surface of a housing 12 of an electronic device (not shown), and a label 14 composed of a rectangular sheet attached to the concave portion 13. It is composed of. The term "label" as used herein is a general term including a label on which information related to this electronic device is described and a sheet-like member such as a sticker having a function equivalent to that of the label. An adhesive made of double-sided tape is attached to the back surface of the label 14. In this embodiment, the housing 12 corresponds to the "member to which the label is attached" in the present invention.

The housing 12 is a molded product made of a synthetic resin material. That is, the housing 12 is formed by injecting a molten synthetic resin material into a mold (not shown) and solidifying it, and then releasing the solidified synthetic resin material from the mold. The recess 13 is a non-through hole formed on the surface of the synthetic resin material after the solidified synthetic resin material is separated from the mold.

As shown in FIG. 2, the recess 13 extends from the opening 21 formed on the surface of the housing 12 and the opening 21 toward the inside of the housing 12 (lower side in FIG. 2) with the opening 21 as one end. It is formed by a side wall 22 and a bottom wall 23 connected to the other end of the side wall 22 and extending in a direction intersecting the side wall 22.
The opening 21 according to this embodiment is formed in a shape into which the label 14 can be inserted, that is, a quadrangle slightly larger than the label 14.

The bottom wall 23 of the recess 13 has a groove 24 formed at a boundary portion with the side wall 22 and a flat label-attached surface 26 extending from the groove wall 25 facing the side wall 22 in the groove 24 to the side opposite to the side wall 22. have. The grooves 24 shown in FIGS. 2 to 4 are formed in a shape in which the deepest bottom 24a is a flat surface. The groove 24 may be formed in a shape such that the bottom 24a has a concave curved surface, as shown in FIG. 5, for example.
The groove 24 is formed in a series along the side wall 22 of the recess 13 in the entire area around the recess 13 without interruption. Therefore, the label sticking surface 26 is surrounded by the groove 24 over the entire surrounding area.

As shown in FIGS. 2 and 3, the boundary portion between the bottom 24a of the groove 24 and the side wall 22 and the boundary portion between the bottom 24a of the groove 24 and the groove wall 25 are molded in the same manner as in the conventional pasting structure. Each of the rounded portions 31 having a concave curved surface formed by the above is provided. The depth of the groove 24 is the depth at which these rounded portions 31 are accommodated in the groove 24. That is, the depth D of the groove 24 is larger than the radius of curvature R of the rounded portion 31. Therefore, the rounded portion 31 is located on the back side of the label 14 by the depth of the groove 24 as compared with the conventional case. In FIG. 3, the conventional rounded portion 6 is drawn by a two-dot chain line.

In order to attach the label 14 to the label attaching surface 26, one end of the label 14 is applied to, for example, one side wall 22 of the recess 13 and along the side wall 22, and the label 14 is directed from one end side to the other end side. This can be done by sequentially pressing against the sticking surface 26. As shown in FIG. 1, the size of the label 14 (the size of the opening 21 of the recess 13) is the width W1 between one end and the other end of the label 14 and the one end and the other end of the opening 21 of the recess 13. It is desirable to set the difference W3 from the width W2 between the two to be narrower than the groove width W4 of the groove 24.

The reason for this is that, as shown in FIG. 2, at least a part of the label 14 (the end portion 14a of the label 14 which is at least one side of the quadrangle) protrudes from the label sticking surface 26 toward the groove 24. The end portion 14a overlaps with the groove 24 in a state where a predetermined gap G is formed between the end portion 14a and the side wall 22 when viewed from the opening side of the recess 13.
When the gap G is generated in this way, as shown in FIG. 4, for example, a tweezers-shaped peeling tool 32 for peeling the label 14 can be inserted into the groove 24 from the gap G. The label 14 can be peeled off by pinching the end portion 14a of the label 14 with the peeling tool 32.

In the sticking structure 11 of the label 14 configured in this way, since the groove 24 is formed at the boundary portion between the side wall 22 of the recess 13 and the bottom wall 23, the label 14 is viewed from the opening 21 side of the recess 13. The end portion 14a of the label 14 can be attached so as to overlap the groove 24. The end portion 14a of the label 14 is in a state of projecting from the bottom wall 23 of the recess 13 toward the opening 21 side of the groove 24. A rounded portion 31 is formed at the boundary portion between the side wall 22 of the recess 13 and the bottom 24a of the groove 24 as in the conventional case. The rounded portion 31 is located on the back side of the label 14 by the depth of the groove 24 as compared with the conventional case.

Therefore, the end portion 14a of the label 14 is in a stretched state without bending without contacting the rounded portion 31, or is in contact with a portion having a small protrusion amount with respect to the side wall 22 such as the starting point of the rounded portion 31. It will be in the state of only. As a result, the label 14 can be securely attached to the bottom wall 23 of the recess 13. Such a sticking state is the same even when the rigidity of the label 14 is high.
Therefore, according to this embodiment, it is possible to provide a label sticking structure in which the label 14 is surely stuck to the bottom wall 23 of the recess 13 even though the rounded portion 31 is formed in the recess 13.

According to this embodiment, the peeling tool 32 is inserted into the groove 24 from the gap G between the end 14a of the label 14 and the side wall 22, and the end of the label 14 is sandwiched between the peeling tools 32. The label 14 can be peeled off by turning over. Therefore, according to this embodiment, it is possible to provide a label sticking structure capable of easily performing the work of peeling off the label 14.

In this embodiment, the housing 12 to which the label 14 is attached is a molded product made of a synthetic resin material. The depth of the groove 24 is the depth at which the rounded portion 31 at the boundary between the bottom 24a of the groove 24 and the side wall 22 is accommodated in the groove 24.
Therefore, by adopting this embodiment, it is possible to surely prevent the end portion 14a of the label 14 from coming into contact with the rounded portion 31, so that the label 14 can be attached more reliably.
Moreover, when one end of the label 14 is applied to the side wall 22 of the recess 13 for attaching the label 14, the rounded portion 31 does not serve as a guide for guiding one end of the label 14 to the outside of the recess 13. Therefore, the pasting work can be smoothly performed.

The groove 24 according to this embodiment is formed in the entire area surrounding the label-attached surface 26.
Therefore, even when the label 14 having a size such that the gap G between the label 14 and the side wall 22 of the recess 13 becomes minute is used, the entire circumference of the label 14 is stretched without bending. Can be.
Therefore, as long as the label 14 fits in the recess 13, any size of the label 14 can be reliably attached.

In the above-described embodiment, an example is shown in which the opening shape of the recess is quadrangular. However, the shapes of the recess 13 and the label 14 are not limited to the quadrangle and can be changed as appropriate. The shape of the recess 13 and the label 14 may be, for example, a triangle, a circle, an ellipse, or the like.
Further, in the above-described embodiment, an example is shown in which the housing 12 is a molded product made of a synthetic resin material. However, the present invention can be applied even if the housing 12 is a metal member molded into a predetermined shape by a die casting method using a metal material.
