[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates, for example, to a package of an object using leather, in which objects such as various knobs and handles of an automobile are packaged using leather.

[0002]

2. Description of the Related Art The applicant of the present invention has previously filed a patent application for a similar invention. (Japanese Patent Application No. 4-170915) In the invention described above, various knobs 51 of an automobile or an object such as a steering wheel (not shown) as shown in FIG.
Using the leather 54 decorated and sewn as described above and packaging with an adhesive, a package as if packaged by hand sewing can be obtained in mass production.

[0003]

However, the above-mentioned invention has the following drawbacks. This results in insufficient removal of the release agent or the like adhering to the object and poor adhesion due to the material. In addition, a defect occurs at the joint of the leather due to the stress generated by the contraction of the leather. This is described as follows: (1) In the case of an object made of a material to which the adhesive does not adhere at all, or an object of a material which is difficult to adhere and cannot obtain a sufficient adhesive force, (2) a release agent used in molding the object ( The release agent remains due to the unevenness of spraying and washing of silicon etc.,
(3) In the case where the adhesive performance varies or causes poor adhesion (3) In the case where the applied adhesive is adversely affected by the substance contained in the object and causes the adhesive variation or poor adhesion (amine catalyst of polyurethane, etc.) (4) Trichloroethylene, etc., which is currently approved as a cleaning agent, is legally restricted and makes it impossible or insufficient to remove the release agent, causing uneven adhesion and poor adhesion. (5) Included in the object The substance is bloomed or bleeds over time due to the environment (temperature, humidity, etc.)
When reducing adhesive strength

[0004] Next, with respect to the problem that occurs at the joint of the leather, the stress caused by the contraction of the used leather caused by sunlight, temperature, humidity and the like during use is shown in FIG.
As shown in FIG. 5, the mouth opening of the joint portion of the leather and the breakage of the base material 56 (FIG. 15) of the hem 55 shown in FIG. 13 (in the case of an object having a resin or the like formed on the surface of the core material 57) occur.

The present invention has been made to solve the above-mentioned various problems, and has the following objects. (1) Adhesive leather winding is possible for an object made of a material to which an adhesive does not adhere at all. (2) Eliminate variations in adhesive strength due to residual mold release material, and ensure sufficient adhesive strength. (3) When applied directly to the adhesive and the base material, depending on the material, the open time, adhesive strength, etc. of the adhesive may vary depending on the substances contained therein (especially the residual amine catalyst contained in foamed polyurethane, etc.). May be adversely affected, but this can be prevented. (4) If the removal of the release agent becomes impossible or insufficient due to the ban on the use of trichlorethylene or the like, the bonding method can be performed without removing the release agent. (5) Prevention of deterioration of the adhesive layer when a substance contained in an object blooms or bleeds after elapse of time due to the environment (temperature, humidity, etc.), (6) Bonding of leather caused by contraction force of leather (7) Prevention of breakage of base material of leather joint caused by contraction force of leather (8) Prevention of breakage of base material of hem caused by contraction force of leather The object is to provide a package of an object made of leather.

[0006]

The invention which achieves the above object is described by adhering to a small portion 3 of an outer surface 2 of an object 1 using an adhesive 4 which is hard to solidify even with the passage of time. Medium leather 5; outer surface 2 of the object 1
Outer skin 8 positioned over the entire surface of the major part 6 other than the small part 3 and the surface 7 of the intermediate leather 5; provided on the surface 7 of the intermediate leather 5 and between the external leather 8 Adhesive 9 which solidifies with the passage of the given time;
A package for an object made of leather, comprising edges 10 and 10 of the outer leather 8 positioned via the adhesive 9 and in contact with each other.

[0007] Further, the edge portions 10 and 10 are thread 11
It is a package of an object using the leather, which is decoratively sewn by the above method. The object 1 is composed of an inner core material 13 and an outer base material 14, and the middle leather 5 and the outer leather 8 are formed of the base material 14.
It is a package of an object using the above-mentioned leather which is located on the top.

[0008]

The present invention is constructed as described above. (A) Since the pressure-sensitive adhesive 4 adheres to almost all objects and keeps the state, the object 1 and the base material 14 are not limited. However, the intermediate leather 5 can be satisfactorily adhered to this and temporarily fixed. (B) The substance contained in the object 1 (such as an amine-based catalyst in the case of foamed polyurethane) has no effect on the adhesive 9 because the intermediate leather 5 blocks the object 1 from the adhesive 9. (C) Adhesion and packaging are possible even when the release agent of the object is insufficiently washed. (D) Further, if the intermediate leather 5 can be temporarily fixed to the object 1 by the adhesive force without washing, there is no problem in the production. (E) Deterioration of the adhesive 9 due to bleeding of the substance contained in the object 1 after a lapse of time in actual use can also be prevented from causing a problem because the intermediate leather 5 serves as a protective layer. (F) Even when shrinkage stress occurs in the outer leather 8, the base material 14
Since the generated stress is not transmitted, the base material 14 does not break or break due to the stress. (G) Since the outer leather 8 is adhered to the intermediate leather 5 with an adhesive 9 having sufficient strength, the mouth of the joint does not open. (H) The direction of shrinkage of the outer leather 8 differs depending on the shape, but since this structure is not bonded to the object 1, it can be freely shifted in any direction, and the generated stress is reduced. Therefore, it is possible to prevent the opening, breakage and breakage of the joint portion, which are problems of the bonding method in practical use, and to greatly improve the durability. (I) Since the mouth opening depends on the strength of the middle leather 5, by selecting a high-strength member to be replaced with the middle leather 5 as long as it can be bonded, it is possible to further extend the durable years until the mouth opening. The appearance does not change at all.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 3, reference numeral 1 denotes an object, which is actually various knobs or handles of an automobile. The small leather 3 is adhered to the small portion 3 of the outer surface 2 by the adhesive 4. Most of the outer surface 2 of the object other than the small portion 6
The outer leather 8 is positioned over the front part of the surface 7 of the middle leather 5 and is adhered to the surface of the middle leather 5 by an adhesive 9 attached thereto. Reference numerals 10 and 10 denote end portions of the outer leather, which are provided in contact with each other. In the present invention, leather refers to leather and synthetic leather.

In FIG. 5, reference numeral 11 denotes a thread, and the end portions 10 and 10 are decoratively sewn, respectively. Next, in FIG. 3, reference numeral 13 denotes a core material and 14 denotes a base material. Actually, the core material 13 is a metal as an example, and 14 is a synthetic resin.

FIGS. 4 to 7 show a steering wheel of an automobile. The surface 7 of the middle leather 5 adhered to the handle as the object 1 by an adhesive is applied to the edge of the outer leather 8 by the adhesive 9. Bonded with 10, 10. Reference numeral 11 denotes a yarn.

FIGS. 8 to 10 show a case where a knob of a vehicle is packaged according to the present invention. The knobs shown in FIGS. 11 to 12 are similarly knobs. In this case, the middle leather 5 is provided only at the hem portion. Next, although not shown, a groove corresponding to the thickness of the middle leather 5 may be formed in the object 1 or the base body 14. Alternatively, the end of the intermediate leather 5 is formed thin. By this method, the hand may be formed well. The operation of these embodiments is almost the same as the operation of the present invention, and will not be described.

[0013]

According to the present invention, since the adhesive 4 adheres by the adhesive force due to the constitution as described above, the intermediate leather 5 can be adhered to almost all objects 1 and the base material 4. it can.

Further, the influence of the substance (such as an amine-based catalyst in the case of foamed polyurethane) contained in the object on the adhesive 9 is as follows.
Since the intermediate leather 5 blocks the object 1 and the adhesive 9, no generation occurs. In addition, even if the release agent of the object 1 is insufficiently washed, bonding and packaging can be performed. In addition, even if it is not washed, the medium leather 5
Can be temporarily fixed to the object 1 without any problem in manufacturing. Adhesive 9 due to oozing out of substance contained in object 1 after aging in actual use
Also, the problem of deterioration can be prevented because the middle leather 5 serves as a protective layer.

Even when contraction stress is generated in the outer leather 8, the generated stress is not transmitted to the base material 14, so that the base material 14 does not break or break due to the stress. In addition, since the outer leather 8 is bonded to the intermediate leather 5 with an adhesive 9 having a sufficient strength, there is no occurrence of opening at the joint. The direction of shrinkage of the outer leather 8 differs depending on the shape, but since this structure is not adhered to the object 1, it can be freely displaced in any direction to reduce the generated stress. Therefore, it is possible to prevent the opening, breakage and breakage of the joint portion, which are problems of the bonding method in practical use, and to greatly improve the durability.

Since the mouth opening depends on the strength of the middle leather 5, as long as it can be bonded, by selecting a high-strength member to replace the middle leather 5, it is possible to further extend the durable life until the mouth is opened. It is possible, and there is no change in appearance.
