TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technology capable of effectively utilizing resources by reuse and recycling, and more particularly to a technology for separating a housing from a nameplate, a nonwoven fabric, and the like that are fixedly attached to the housing.
[0002]
[Prior art]
Generally, a nameplate made of paper, vinyl chloride, or the like as a base material, or a nonwoven fabric is adhered and fixed to a housing of an industrial product. The nameplate is used for displaying information such as ratings, cautions / warnings, operation displays, products, and services. The nonwoven fabric is used, for example, to prevent generation of abnormal noise or friction due to resonance caused by sound or vibration generated by a product at a place such as a rib that comes into contact with and fitted between exterior parts. .
[0003]
The case to which these nameplates and nonwoven fabrics are bonded and fixed is made of plastic or metal, and it is necessary to peel off these nameplates and nonwoven fabrics made of different kinds of materials from the case when the cases are reused or recycled. .
[0004]
As a technique for peeling a nameplate, there is a technique in which a through hole is formed in a nameplate affixing region of a housing (for example, see Patent Document 1). In this peeling structure, a nameplate peeling pin is inserted into the through hole from the inner surface side of the casing, and the nameplate peeling pin is brought into contact with the inner surface of the nameplate and pressed, whereby the nameplate is peeled.
[0005]
Further, there is a case in which a bag hole protruding from the back surface of the case is provided on the nameplate bonding surface of the case (for example, see Patent Document 2). In this case structure, when the nameplate is peeled, the blind hole is cut, a standard tool is inserted from the bottom surface, and the nameplate is peeled by pressing the backside of the nameplate.
[0006]
Further, there is a base material provided with a cut portion that can be easily cut around a portion where the nameplate is attached (see, for example, Patent Document 3). Then, by the cutting of the cut portion, the attached portion is separated from the base material.

[Problems to be solved by the invention]
However, in the technique disclosed in Patent Document 1, since a part of the bonding surface of the nameplate is directly exposed inside the housing, there is a problem that dust adheres to a part of the bonding surface.
[0009]
Further, according to the technology disclosed in Patent Literature 2, it is necessary to cut the blind hole with a predetermined cutting tool, then switch to another tool and press the nameplate from the inside, which takes time and effort to separate the nameplate. There was a problem.
[0010]
Furthermore, in the technique disclosed in Patent Document 3, the nameplate-attached portion of the substrate is separated from the base material, so that the base material itself cannot be reused. However, there is a problem that it is difficult to recycle them as resources because they remain in a form as they are adhered.
[0011]
Therefore, an object of the present invention is to provide a technique capable of separating a nameplate from a housing more completely and easily without exposing an adhesive surface to an opposite surface side.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention is a case in which a sticking area is provided in a case main body, wherein a peeling groove is formed from a part of the sticking area outer peripheral part toward the inside thereof. It is.
[0013]
Further, in the case where the sticking area is provided in the housing body, an annular sticking projection is provided at a peripheral portion in the sticking area, and at least one sticking projection is provided in the annular sticking projection. It is a thing.
[0014]
Furthermore, it is an attachment having an attachment surface, wherein a peeling groove is formed from a part of an outer peripheral portion of the attachment surface toward an inside thereof.
[0015]
Further, a peeling groove is formed from a part of the outer peripheral portion toward the inside on a sticking area provided on the housing body or a sticking surface of the sticking material which is adhered and fixed to the housing body, and the sticking material is peeled. In the method of preparing a tool having a flat tip, and inserting the tip of the tool into the separation groove, in the direction of lifting the base end side of the tool from the housing body. It is moved to peel off the patch.
[0016]

[0017]
This housing structure includes a housing 10 in which a sticking area 14 is provided in a housing body 12, and a nameplate 20 stuck to the sticking area 14.
[0018]
The housing 10 is used as a case body of, for example, a computer device, an OA (office automation) device, an AV (audiovisual) device, or the like. Such a case 10 is formed of, for example, plastic.
[0019]
The housing main body 12 is formed in a housing shape, and a sticking area 14 is provided on a part of an outer surface thereof. The sticking area 14 may be provided on any of the upper surface, each side surface, and the lower surface of the housing main body 12 in a normal use state of the device incorporating the housing 10. Further, it may be provided on the inner surface of the housing body 12, a partition wall, or the like.
[0020]
The attachment region 14 has substantially the same shape and size as the nameplate 20. In the present embodiment, the attachment region 14 is formed in a substantially square shape, and has a shape that is recessed one step from its outer periphery. Note that the attachment region 14 may be flush with its outer periphery.
[0021]
The nameplate 20 is formed in a plate shape, and in this embodiment, is formed in a substantially rectangular plate shape. On the nameplate 20, predetermined information is described, and in the present embodiment, information such as the model name, rated voltage, and serial number of the device is described. The nameplate 20 is formed of metal, plastic, or the like. When the nameplate 20 is formed of plastic, generally, the nameplate 20 is formed of plastic of a different material from the plastic forming the housing 10. The nameplate 20 is bonded and fixed to the entire sticking area 14 using an adhesive or a double-sided tape. In addition, as the pasted object to be pasted on the pasting region 14, for example, in addition to the name plate 20 described above, a design part (see the operation panel shown in FIG. 8) formed of acrylic or the like, or for noise prevention and vibration absorption, A nonwoven fabric for friction prevention and the like can be mentioned (see FIG. 9). In short, the present invention can be applied to a case where another attached object is bonded and fixed to the housing body 12.
[0022]
Further, a peeling groove 17 is formed from a part of the outer peripheral portion of the attachment region 14 toward the inside thereof. In the present embodiment, the separation groove 17 is formed so as to extend from a substantially central portion of one long side of the sticking region 14 formed in a substantially square shape toward the center of the sticking region 14. When the sticking area 14 is formed on the side surface of the housing body 12, the peeling groove 17 is located inside (ie, above) the lower side of the sticking area 14 in a normal use state of a device incorporating the housing 10. ). Accordingly, the opening side of the separation groove 17 is directed downward, and it is possible to reduce entry of water droplets and dust into the separation groove 17.
[0023]
In addition, an insertion opening 18 is formed at a position corresponding to the opening side of the peeling groove 17 on the outer peripheral side surface 14 a surrounding four sides of the attachment region 14. A tip portion of a tool described later is inserted into the separation groove 17 through the insertion opening 18.
[0024]
Here, the relationship between each dimension of the stripping groove 17 and each dimension of the insertion opening 18 and each dimension of the stripping tool will be described.
[0025]
In this embodiment, a case will be described in which a flathead screwdriver is used as a peeling tool, in particular, a flathead screwdriver conforming to JIS defined in JIS B4609.
[0026]
First, the configuration of the flathead screwdriver itself will be described.
[0027]
FIG. 5 is a perspective view showing the shape of a JIS standard flathead screwdriver. FIG. 5 (a) is a perspective view showing the shape of the blade tip 32A of a flathead screwdriver for "screwdriver-for slotted screws" defined in JISB4609, and FIG. FIG. 5 (b) is a perspective view showing the shape of a blade tip 32C of a flathead screwdriver assumed in the JIS standard described above.
[0028]
According to JIS B4609, when the plate thickness at the tip of the cutting edges 32A, 32B, and 32C is a and the plate width is b, the plate thickness a and the plate width b are defined in the following ranges. That is, in the “screwdriver-for slotted screw” shown in FIG. 5A, the range of 0.6 ≦ a ≦ 1.2, 4.5 ≦ b ≦ 10, and the attachment shown in FIG. In the book “I-type screwdriver—for slotted screws”, the range is defined as 0.4 ≦ a ≦ 2.5 and 2 ≦ b ≦ 14.
[0029]
Even with such a flathead screwdriver defined by the JIS standard, the thickness of the blade generally increases from the tip of the cutting edge 32A, 32B, 32C in the direction of the handle. The diameter is increased up to the diameter of a substantially circular cross section that becomes the shaft 33 of the flathead screwdriver. Further, usually, the width of the plate fluctuates in the direction of the handle from the tip of the blade edges 32A, 32B, 32C. Assuming that e is the middle width of the maximum width portion or the minimum width portion closer to the base end than the cutting edges 32A, 32B, and 32C, and α is the difference between the middle width e and the plate width b, FIG. In the flathead screwdriver shown in a), the width e of the intermediate portion becomes larger than the diameter of the shaft 33, and α> 0. Further, α = 0 for the minus driver shown in FIG. 5C, and α <0 for the minus driver shown in FIG. 5B.
[0030]
On the other hand, the groove depth dimension of the stripping groove 17 is c and the groove width dimension is d.
[0031]
In this case, in order to peel the nameplate using a flathead screwdriver specified by the JIS standard, the groove depth c and the groove depth dimension c must be set to a size that allows the blade edges 32A, 32B, and 32C of the flathead screwdriver to be inserted into the peeling groove 17. The groove width dimension d needs to be set.
[0032]
That is, the groove depth dimension c of the stripping groove 17 is larger than the plate thickness dimension a at the tip end of the cutting edge 32A, 32B, 32C, and the groove width dimension d is the plate width of the cutting edge 32A, 32B, 32C. It must be larger than the larger dimension (maximum width dimension) of the dimension b and the intermediate section width dimension e.
[0033]
For example, the groove depth dimension c is set to be larger (for example, several percent) than the plate thickness dimension a of the tip of the blade edge 32A, 32B, 32C of the minus screwdriver defined in the range of 0.4 mm ≦ a ≦ 2.5 mm. . In addition, when the groove width dimension d is α ≧ 0 (see FIGS. 5 (a) and 5 (c)), the blade tip 32A of the flathead screwdriver is determined within the range of 2 mm ≦ e ≦ (14 + α) mm. The edge widths 32A, 32B, and 32C are set to be larger (for example, several percent) than the width e of the intermediate portion of 32B and 32C, and in the case of α <0 (see FIG. 5B), the range of 2 mm ≦ b ≦ 14 mm. Is set to be larger (for example, several percent) than the plate width dimension b at the tip end of.
[0034]
Further, the opening width dimension d and the opening length dimension f need to be set to such a size that the blade edges 32A, 32B, 32C of the flathead screwdriver can be inserted into the insertion opening 18.
[0035]
For this purpose, for example, the opening width of the insertion opening 18 is set to the same d as the groove width. Further, the opening length dimension f of the insertion opening 18 is set to a dimension larger than the groove depth dimension c, that is, f ≧ c. Note that the opening length of the insertion opening 18 is defined as a length in a direction orthogonal to the opening width direction of the insertion opening 18.
[0036]
The length of the peeling groove 17 is preferably set to be approximately half the length of the sticking area 14 in the extending direction. In the present embodiment, the length of the peeling groove 17 is set to be approximately half the length of the short side of the attachment region 14. As a result, approximately half the area of the nameplate 20 can be peeled off using a flathead screwdriver. Note that the length of the peeling groove 17 does not need to be strictly set to half of the length of the sticking area 14, and the above-described effect can be obtained even if the length is about the length. Further, the peeling groove 17 may be formed over the entire length of the attachment region 14.
[0037]
Next, a method of peeling the nameplate 20 in this embodiment will be described.
[0038]
First, the blade tip 32A of the JIS standard flathead screwdriver 30 is inserted into the insertion opening 18 provided on the outer surface side of the housing main body 12, and the blade tip 32A is directed to the back side of the peeling groove 17. 30 is inserted into the peeling groove 17 further inside while tilting.
[0039]
Here, the groove depth dimension c and the groove width dimension d of the peeling groove 17 and the opening length dimension f and the groove depth dimension c of the insertion opening 18 are, for example, intermediate between the cutting edge 32A of the flathead screwdriver 30 defined in the JIS standard. The width d is set to be larger than the width d or the thickness a. Therefore, the blade edge 32 </ b> A of the flathead screwdriver 30 can be inserted through the insertion opening 18 to the inner side of the separation groove 17.
[0040]
Then, in a state where the cutting edge 32A is inserted to the depth side or halfway of the peeling groove 17 and is brought into contact with the bottom of the peeling groove 17, the handle 31 of the flathead screwdriver 30, which is the base end side of the tool, is attached to the sticking area. Move from 14 to the lifting direction. That is, the adhesive surface of the nameplate 20 is pushed up by using the lever principle of using the blade edge 32A of the flathead screwdriver 30 as a fulcrum and the adhesive surface of the nameplate 20 as a point of action and the handle 31 of the flathead screwdriver 30 as a power point. Thereby, one side portion of the nameplate 32 can be lifted from the sticking area 14 with relatively light force. Thereafter, when the user lifts one side of the nameplate 32 by grasping it by hand, the nameplate 20 can be separated from the attachment area 14 and separated from the housing body 12.
[0041]
According to the housing configured as described above, the nameplate 20 can be more easily separated from the housing body 12 by inserting the flathead screwdriver 30 as a tool into the separation groove 17. In particular, the nameplate 20 can be peeled off with a relatively small force by the leverage principle. Thereby, the workability of reuse and recycling can be improved.
[0042]
In addition, since the nameplate 20 can be peeled off with a relatively small force by inserting the flathead screwdriver 30 into the peeling groove 17, the housing body 12 is less likely to be scratched. Even if the bottom of the peeling groove 17 may be scratched by the flathead screwdriver 30 during the work of peeling the nameplate 20, there is no particular problem because another nameplate is again attached to the sticking area 14 at the time of reuse. .
[0043]
At this time, since only the nameplate 20 can be separated from the housing body 12, more complete separation can be achieved. Further, it is not necessary to expose the adhesive surface of the nameplate 20 in the housing 10 in a state where the nameplate 20 is attached.
[0044]
Further, since the groove depth dimension c and the groove width dimension d are set to a size in which the blade edges 32A, 32B, 32C of the flathead screwdriver can be inserted into the peeling groove 17, special tools as in the related art are used. The nameplate 20 can be peeled off using a general flathead screwdriver without using a flathead screwdriver. In particular, by setting the groove depth dimension c and the groove width dimension d of the peeling groove 17 to a size corresponding to a JIS standard minus driver, the JIS standard minus screw commonly used in factories and the like can be obtained. The nameplate 20 can be peeled off using a screwdriver.
[0045]
When using a flathead screwdriver other than the JIS standard, with a tool larger than the standard, the width and thickness of the blade edge do not match the size of the separation groove 17 and cannot be inserted into the separation groove 17. hard. Further, although the nameplate 20 can be inserted into the peeling groove 17 with a tool smaller than the standard, the nameplate 20 is easily damaged because the blade of the tool is thin at the time of peeling.
[0046]
Embodiment 2 FIG.
FIG. 6 is a perspective view for explaining a housing structure according to Embodiment 2 of the present invention, and FIG. 7 is a sectional view taken along line VII-VII of FIG.
[0047]
The same components as those described in the first embodiment are denoted by the same reference numerals, the description thereof will be omitted, and the description will focus on differences.
[0048]
This housing structure includes a housing 110 in which a sticking area 114 is provided in a housing body 112, and a nameplate 20 stuck to the sticking area 114.
[0049]
The housing 110 and the housing main body 112 have the same configuration and functions as those of the housing 10 and the housing main body 112, respectively, except for the configuration related to the sticking area 114 described below.
[0050]
The attachment area 114 has substantially the same shape and size as the nameplate 20. In the present embodiment, the attachment region 114 is formed in a substantially square shape, and has a shape that is recessed one step from its outer periphery.
[0051]
In addition, an annular sticking projection 115 is provided at a peripheral portion in the sticking area 114, and at least one sticking projection 116 is provided in the annular sticking projection 115.
[0052]
In the present embodiment, annular attaching protrusion 115 is formed in a rectangular frame shape corresponding to the peripheral shape of attaching region 114.
[0053]
A plurality of strip-shaped sticking projections 116 are formed in parallel in the annular sticking projection 115 at predetermined intervals.
[0054]
The respective projecting surfaces of the annular sticking projections 115 and the sticking projections 116 are disposed at substantially the same projecting height position. Then, the plate-shaped nameplate 20 is adhered and fixed so as to be attached to the protruding surface of the annular attaching protrusion 115 and the protruding surface of each attaching protrusion 116. At this time, since the peripheral edge of the nameplate 20 is adhered to the protruding surface of the annular attaching projection 115, the adhesion can be prevented from peeling off or floating from the peripheral edge side of the nameplate 20.
[0055]
In this case, the bonding area between the nameplate 20 and the respective projecting surfaces of the annular sticking projections 115 and the sticking projections 116 is the same as that in the first embodiment when the entire back surface of the nameplate 20 is adhesively fixed to the sticking area 14. It is smaller than the bonding area. For this reason, the adhesive force of nameplate 20 in the second embodiment can be made relatively weak, and nameplate 20 can be peeled off relatively easily.
[0056]
In addition, the adhesive force of the nameplate 20 is adjusted by an adhesive area corresponding to each projecting surface of the annular sticking projection 115 and each sticking projection 116. For example, if the annular sticking projections 115 and the respective sticking projections 116 are made thinner or the number of the sticking projections 116 is reduced, the bonding area becomes smaller and the adhesive strength of the nameplate 20 is reduced. In addition, if the annular sticking projections 115 and the sticking projections 116 are made thicker, or if the number of the sticking projections 116 is increased, the bonding area increases, and the adhesive strength of the nameplate 20 increases.
[0057]
Note that the sticking projection 116 does not necessarily need to have a band shape, and may have a projecting shape having a substantially square or substantially circular sticking surface.
[0058]
Further, in the attachment region 114, a separation groove 117 and an insertion opening 118 having the same shape as the separation groove 17 and the insertion opening 18 are formed.
[0059]
The setting of the groove width dimension d and the groove depth dimension c of the peeling groove 117 and the preferable setting ranges of the dimensions of each part of the insertion opening 118 are the same as those described in the first embodiment.
[0060]
A method of separating the nameplate 20 according to this embodiment will be described.
[0061]
First, the blade edge 32A of the flathead screwdriver 30 is inserted into the insertion opening 118, and the flathead screwdriver 30 is inclined to push the blade edge 32A into the peeling groove 117 at the back.
[0062]
Then, in a state where the blade edge 32A is inserted into the depth side or halfway of the peeling groove 117 and is brought into contact with the bottom of the peeling groove 117, the handle 31 of the flathead screwdriver 30 is removed similarly to the case of the first embodiment. Is moved from the attachment area 114 in the lifting direction. That is, the adhesive surface of the nameplate 20 is pushed up by using the lever principle of using the blade edge 32A of the flathead screwdriver 30 as a fulcrum and the adhesive surface of the nameplate 20 as a point of action and the handle 31 of the flathead screwdriver 30 as a power point. Thereby, one side portion of the nameplate 20 can be lifted from the attachment area 114 with relatively light force. Thereafter, when the user lifts one side portion of the nameplate 20 by grasping it by hand, the nameplate 20 can be separated from the sticking area 114 and separated from the housing body 112.
[0063]
According to the housing according to the second embodiment, the adhesive strength of nameplate 20 can be made relatively small by the adhesive area of annular attaching protrusion 115 and each attaching protrusion 116 provided in attachment region 114. For this reason, the nameplate can be easily peeled off with a relatively small force.
[0064]
At this time, since only the nameplate 20 can be separated from the housing body 112, more complete separation can be achieved. Further, in a state where the nameplate 20 is attached, the adhesive surface does not have to be exposed inside the housing 110.
[0065]
Further, since the separation groove 117 similar to the separation groove 17 in the first embodiment is formed, the same operation and effect as described in the first embodiment can be obtained.
[0066]
Embodiment 3 FIG.
FIG. 8 is a perspective view for explaining a housing structure according to Embodiment 3 of the present invention.
[0067]
This housing structure includes a housing 210 in which a sticking area 214 is provided in a housing body 212, and an operation panel 220 stuck to the sticking area 214.
[0068]
The housing 210 and the housing main body 212 have the same configurations and functions as the housing 10 and the housing main body 212 in the first embodiment, respectively, except for the configuration described below.
[0069]
The attachment area 214 has substantially the same shape and size as the operation panel 220. In the present embodiment, the attachment region 214 is formed in a substantially square shape, and has a shape that is recessed one step from its outer periphery. Note that the attachment region 214 may be flush with its outer periphery.
[0070]
Unlike the first embodiment, the attachment region 214 does not have the separation groove 17 and is formed on a substantially flat surface as a whole.
[0071]
The operation panel 220 is formed in a plate shape. In the present embodiment, the operation panel 220 is formed in a substantially rectangular plate shape with acrylic or the like, and has a configuration in which buttons 220a, 220b, and 220c for operating devices are arranged on one surface side. . With the operation panel 220 adhered and fixed to the housing main body 212, the buttons 220a, 220b, 220c are electrically connected to electric components in the housing main body 212 via wiring not shown. It should be noted that the attachment to be attached and fixed to attachment region 214 may be a nameplate or the like as described in the first embodiment.
[0072]
A peeling groove 222 is formed on the attachment surface 221 that is the other surface of the operation panel 220. The peeling groove 222 is formed so as to extend from a part of the outer peripheral portion of the attachment surface 221 toward the inside thereof.
[0073]
In the present embodiment, the peeling groove 222 is formed so as to extend from the substantially central portion of one short side of the substantially rectangular attaching surface 221 toward the central portion of the attaching surface 221.
[0074]
An insertion notch 223 is formed on the periphery of the operation panel and on the opening side of the peeling groove 222 so as to penetrate the operation panel 220 from front to back.
[0075]
The preferable setting range of the groove width dimension and the groove depth dimension of the separation groove 222 is the same as the range described for the separation groove 17 in the first embodiment.
[0076]
The groove width of the peeling groove 222 and the width of the insertion notch 223 are formed to be substantially the same, and the groove depth of the peeling groove 222 and the notch depth of the insertion notch 223 are formed. It is good to form so that it may become substantially the same.
[0077]
A peeling method according to Embodiment 3 will be described.
[0078]
First, for example, a blade of a flathead screwdriver of JIS standard or the like is inserted into the insertion notch 223, and the blade is pushed into the peeling groove 222 while tilting the flathead screwdriver. At this time, similarly to the first embodiment, the tip of the blade of the flathead screwdriver can be inserted all the way into the separating groove 222.
[0079]
Then, with the blade edge in contact with the sticking area 214, the handle of the flathead screwdriver is moved in the direction of lifting from the housing 210. That is, the sticking surface of the operation panel 220 is formed using the principle of leverage with the blade point of the flathead screwdriver as a fulcrum, the opening side of the peeling groove 222 on the sticking surface of the operation panel 220 as an action point, and the handle of the flathead screwdriver as a power point. Lifting. Thereby, one side portion of operation panel 220 can be lifted from sticking area 214 with relatively light force. The operation panel 220 can be peeled off from the housing body 212 by grasping and lifting one side of the operation panel 220 by hand.
[0080]
According to housing 210 configured as described above, the same effects as those described in the first embodiment can be obtained.
[0081]
In addition, in the present embodiment, instead of forming the peeling groove 17 on the sticking area 14 side of the housing body 12 as in Embodiment 1, instead of forming the peeling groove 17 on the sticking surface 221 side of the operation panel 220 serving as a sticking object, Since the separation groove 222 is formed, there is an advantage that the configuration of the housing body 12 can be used as it is.
[0082]
In addition, on the attaching surface 221 side of the operation panel 220, a member having the same configuration as that of the annular attaching protrusion 115 and at least one attaching protrusion 116 described in the second embodiment is provided to reduce the adhesive force of the operation panel 220. It may be adjusted.
[0083]
Embodiment 4 FIG.
FIG. 9 is a perspective view illustrating a housing structure according to Embodiment 4 of the present invention.
[0084]
This housing structure includes a housing 310 in which a sticking area 314 is provided in a housing body 312, and a nonwoven fabric 320 stuck to the sticking area 314.
[0085]
The housing 310 is formed of, for example, plastic, similarly to the housing 10, and is used as a case body of a computer device, an OA (office automation) device, an AV (audiovisual) device, or the like.

The housing main body 312 is formed in a housing shape having an opening, and has a rib 316 on the periphery of the opening. The rib portion 316 is formed in an elongated plate shape protruding from the peripheral edge of the opening of the housing main body 312 along the side surface direction of the housing main body 312. The longitudinal direction of the rib portion 316 extends along the direction in which the peripheral edge of the opening of the housing body 312 extends. Then, in a state where the housing main body 312 is combined with another housing main body (not shown), the rib portion 316 is fitted into a coupling recess formed on the opening peripheral portion of the other housing main body. It has become.
[0087]
The nonwoven fabric 320 is formed in a substantially rectangular shape. The nonwoven fabric 320 is bonded and fixed to the outer surface of the rib portion 316 with an adhesive or the like in a state where its longitudinal direction is along the longitudinal direction of the rib portion 316. Note that a portion of the outer side surface of the rib portion 316 to which the nonwoven fabric is attached is an attachment region 314.
[0088]
The rib portion 316 is interposed between the rib portion 316 and the surface on which the coupling concave portion is formed in a state where the housing body 312 and another housing body are combined. Accordingly, at the connection portion between the housing body 312 and another housing body, a function of preventing abnormal noise and friction due to sound, vibration, resonance, and the like generated by the product itself is achieved.
[0089]
In the rib portion 316, a peeling groove 317 is formed from a part of the outer peripheral portion of the attachment region 314 toward the inside thereof. The peeling groove 317 is formed at a position from one end in the longitudinal direction of the nonwoven fabric 320 so as to extend substantially perpendicular to the longitudinal direction of the nonwoven fabric 320. Further, the length dimension of the separation groove 317 is larger than the width dimension of the nonwoven fabric 320, and therefore, the separation groove 317 extends so as to penetrate the nonwoven fabric 320 along the width direction. .
[0090]
Further, an insertion opening 318 is formed on the opening side of the peeling groove 317 and at the opening edge of the housing body 312.
[0091]
The preferable setting range of the groove width dimension and the groove depth dimension of the separation groove 317 is the same as the range described for the separation groove 17 in the first embodiment. The preferred setting range of the opening width and the opening length of the insertion opening 318 is the same as the range described for the insertion opening 18 in the first embodiment.
[0092]
A peeling method according to Embodiment 4 will be described.
[0093]
First, a blade of a flathead screwdriver is inserted into the insertion opening 318. Then, the blade edge is pushed into the separating groove 317 while tilting the flathead screwdriver. At this time, in the same manner as described in the first embodiment, the tip of the blade edge of the flat-blade screwdriver can be inserted to the depth of the peeling groove 317.
[0094]
Then, the handle of the flathead screwdriver is lifted with the cutting edge in contact with the bottom of the peeling groove 317. Thus, the bonding surface of the nonwoven fabric 320 is pushed up using the lever principle of using the blade edge of the flathead screwdriver as a fulcrum, the peripheral edge of the bonding surface of the nonwoven fabric 320 as an action point, and the handle portion of the flathead screwdriver as a power point. This allows one end of the nonwoven fabric 320 to float from the attachment region 314 of the rib 316 with relatively light force. In particular, since the peeling groove 317 extends so as to penetrate the nonwoven fabric 320 along its width direction, the entire width direction of one end of the nonwoven fabric 320 can be brought into contact with the shaft of a flathead screwdriver. Regardless of the presence or absence of the extension of 20, the one end of the nonwoven fabric 320 can be more reliably lifted. Then, the non-woven fabric 320 can be peeled off from the rib 316 by further grasping one end of the non-woven fabric 320 by hand and lifting it.
[0095]
With the housing 310 configured as described above, the same effect as in the first embodiment can be obtained.
[0096]
【The invention's effect】
As described above, according to the housing of the present invention, the attached object can be more completely and easily separated from the housing body by inserting the tool into the separation groove. In this case, it is not necessary to expose the adhesive surface to the opposite side in a state where the patch is attached.
[0097]
Further, according to another case of the present invention, since the adhesive force of the pasted object can be adjusted by the adhesion area of the annular pasting projection and the pasting projection, the pasted object can be completely and easily separated from the housing. In this case, it is not necessary to expose the adhesive surface with the patch attached.
[0098]
Further, according to the patch of the present invention, the patch can be more completely and easily separated by inserting a tool into the separation groove. In this case, it is not necessary to expose the adhesive surface in a state where the patch is attached.
[0099]
Further, according to the peeling method of the present invention, by sticking the tool into the groove for peeling, it is possible to more reliably and easily peel the adhered object. At this time, it is not necessary to expose the adhesive surface of the patch.
