JP2000162866A - Flexible member with tacky adhesive sheet and method for sticking flexible member - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily stick a flexible member by providing the flexible member with a tacky adhesive sheet, having an external shape slightly smaller tan the external shape of the flexible member. SOLUTION: This flexible member 10 with the tacky adhesive sheet is constituted by sticking a tacky adhesive double-coated tape sheet 2 to a sheet material of spongy Moltopren (R) consisting of urethane, etc. The double-coated tape 2 is formed shorter by a size a+b than the length of Moltopren (R). This size a+b is, for example, a size of 0.5 to 1 mm at which rough manual sticking is possible. In such a case, there is no tacky adhesive part of the double coated tape 2 in a portion near the terraced part (rising wall) 3a of a container 3, and therefore, even if the Moltopren (R) is stuck in the position overlapping on the terraced part 3a by the size (b), the sticking of the double-coated tape 2 to the terraced part 3a does not occur, and eventually the sticking position accuracy may be set to the conventional spacing of (0.1 + an overlapping component). Then, the sticking position accuracy may be made rough.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible member with a sticky pressure-sensitive adhesive sheet and a method for attaching the flexible member.

[0002]

2. Description of the Related Art A toner cartridge used in an image forming apparatus or the like has a function of storing fine powder called toner. In such a toner cartridge, a maltprene with a double-sided tape is used in the mating portion of the frame and the rotating sliding portion for the purpose of preventing toner leakage.

[0003] This maltprene with a double-sided tape is prepared by laminating an adhesive double-sided tape sheet to a sponge-like maltprene sheet material made of urethane or the like, and then cutting it into a predetermined shape. 4 has a two-layer structure in which a double-sided tape 5 of the same dimensions is adhered to the external dimensions of FIG.

[0004] Such a maltprene with a double-sided tape is attached to the step portion 3a of the toner container 3 so as to eliminate the gap, but a slight gap of about 0.1 mm is actually required. This is because if the gap C is set to 0, the double-sided tape 5 is stuck to the step portion (standing wall portion) 3a of the container 3 to form a gap d at the corner as shown in FIG. Because you do.

[0005]

However, in the above-mentioned conventional example, since it is stuck to the gap 0.1 shown in FIG. And the work is troublesome and the cost is high.

Accordingly, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a flexible member with a pressure-sensitive adhesive sheet and a method for attaching a flexible member to which a flexible member can be more easily attached. It is to provide.

[0007]

Means for Solving the Problems The above-mentioned problems are solved,
In order to achieve the object, a flexible member with a pressure-sensitive adhesive sheet according to the present invention has a flexible member and a pressure-sensitive adhesive sheet attached to the flexible member and having an outer shape slightly smaller than the outer shape of the flexible member. And characterized in that:

Further, in the flexible member with an adhesive sheet according to the present invention, the flexible member is formed of a sponge-like material.

Further, in the flexible member with an adhesive sheet according to the present invention, the sponge-like material is maltprene.

Further, in the flexible member with an adhesive sheet according to the present invention, the flexible member is used as a sealing material for a toner cartridge of an image forming apparatus.

Further, in the flexible member with a pressure-sensitive adhesive sheet according to the present invention, the outer shape of the pressure-sensitive adhesive sheet is about 0.5 to 1 mm smaller than the outer shape of the flexible member.

[0012] The method of attaching a flexible member according to the present invention is a method of attaching a flexible member for attaching a flexible member with an adhesive sheet to a stepped portion. The outer shape of the flexible member is formed slightly smaller than the outer shape of the flexible member, and the end surface of the flexible member is adhered to the step portion so that the end surface of the pressure-sensitive adhesive sheet does not contact the step portion. It is characterized by attaching.

Further, in the method of attaching a flexible member according to the present invention, the flexible member is formed of a sponge-like material.

In the method of attaching a flexible member according to the present invention, the sponge-like material is maltprene.

Further, in the method for attaching a flexible member according to the present invention, the flexible member is used as a sealing material for a toner cartridge of an image forming apparatus.

Further, in the method of attaching a flexible member according to the present invention, the outer shape of the pressure-sensitive adhesive sheet is smaller by about 0.5 to 1 mm than the outer shape of the flexible member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing one embodiment of the flexible member with an adhesive sheet of the present invention.

In FIG. 1, an adhesive sheet-attached flexible member 10 is constituted by adhering an adhesive double-sided tape sheet 2 to a sponge-like moltoprene sheet material 1 made of urethane or the like. The double-sided tape 2 is formed shorter than the moltoprene 1 by the dimension of a + b.

In this embodiment, the dimension of a + b is 0.5 to 1 mm which can be roughly pasted by hand.

Since there is no adhesive portion of the double-sided tape 2 in a portion near the step portion (standing wall) 3a of the container 3, even if the moltoprene 1 is stuck at a position overlapping the step portion 3a by the dimension b, FIG. As described above, the double-sided tape 2 does not stick to the step portion 3a, and as a result, the accuracy of the sticking position can be set to the conventional value of 0.1 in FIG. That is, the accuracy of the pasting position can be made rougher than before.

After being attached to the container 3, the end of the moltoprene 1 is slightly pressed against the step (standing wall) 3a. Between the end 2a of the double-sided tape 2 and the step 3a of the container 3, a gap corresponding to the thickness of the double-sided tape 2 is formed between the lower surface of the moltoprene 1 and the floor 3b of the container 3. In this case, since a pressing force is applied from the upper surface of the moltoprene 1, this gap is eliminated.

FIGS. 2 to 4 show steps (standing walls) of the container.
It is a figure showing the example of the shape of the flexible member with an adhesive sheet corresponding to the shape of.

FIG. 2 shows a case where the standing wall has one side. Double-sided tape 2A against standing wall of container 6 is Moltprene 1A
Is shorter than the end by a dimension e (actual dimension 0.5 to 1 mm).

FIG. 3 shows a case where the standing wall has two sides. Container 7
The double-sided tape 2A is shorter than the end of the moltoprene 1B by a dimension f in the longitudinal direction and a dimension g (actual dimension 0.5 to 1 mm) in the lateral direction with respect to the standing wall.

FIG. 4 shows a case in which all sides of moltoprene 1C are covered with a wall. The double-sided tape 2C is shorter than the outer dimensions of the moltoprene 1C by h1, h2, i1, i2, and is located substantially at the center of the moltoprene 1C.

It should be noted that the present invention can be applied to a modification or modification of the above embodiment without departing from the spirit thereof.

For example, in the above embodiment, the flexible member is described as maltprene. However, the present invention is not limited to this, and other flexible materials such as rubber and felt may be used.

[0029]

As described above, according to the present invention,
Since the flexible member can be attached to the container wall without concern for the gap of 0.1 mm, the following effects can be obtained. (1) Since it can be pasted with rough accuracy, the labor of the operation can be reduced and the cost can be reduced. (2) It is easy to use an automatic machine.
