BACKGROUND OF THE INVENTION
The present invention relates to a disposable cover, and can be attached to an object to be attached such as a seat without any engaging element such as a front fastener (for example, Velcro fastener).
[0002]
[Prior art]
Disposable covers intended for use in aircraft and railway vehicle seats include techniques disclosed in Japanese Utility Model Registration No. 2588266, Utility Model Registration No. 2547079, and Japanese Patent No. 2650085. In these techniques, the cover uses a non-woven fabric as a material instead of a conventional woven fabric. The seat is provided with several Velcro fastener-type engaging elements (so-called Velcro hooks) (for example, two places spaced apart in the width direction on the back side of the seat), and on the seat side are engaging protrusions that engage with the Velcro hook. A member is provided. The engaging projecting member is constituted by a synthetic fiber yarn (synthetic fiber filament twisted yarn) bonded so as to extend in the width direction on one end side of the nonwoven fabric as described above, in the utility model. The twisted yarn protrudes somewhat from the nonwoven fabric surface at one end in the longitudinal direction of the cover, and when the cover is attached to the seat, the twisted yarn protruding from the nonwoven fabric surface can be engaged with the Velcro hook on the seat back side.
[0003]
[Problems to be solved by the invention]
In the prior art disclosed in the above-mentioned prior utility models or patents, the cover and the seat are fastened by a Velcro fastener type engagement method. That is, a synthetic resin velcro hook is fixed to the seat side, and a synthetic resin filament twisted yarn is bonded to the cover side so as to be engaged therewith. Therefore, the cost is high, and further cost reduction is desired.
[0004]
The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a disposable cover that can be securely attached without using a Velcro fastener method.
[0005]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a disposable cover that can be mounted on an object to be mounted such as a seat without any engaging element such as a front fastener type, and is a cover body formed of a nonwoven fabric. And at least one end of the cover body is coated with an adhesive over a region having a predetermined width so as to extend in the width direction of the cover body, and the release sheet is on the side close to the end of the cover body. The appropriate width area of the coating layer is covered and the remaining area of the adhesive coating layer is affixed to the adhesive coating layer so as to be exposed as an effective area of the adhesive, facing the adhesive coating layer side. On the surface of the peeled sheet, a surface treatment layer made of a material that is difficult for adhesives such as silicone to adhere is formed. The cover body is folded and peeled in the vicinity of the boundary line between the surface treatment layer and the adhesive coating layer. Shi Disposable cover of which the pressure-sensitive adhesive effective working region in the adhesive coating layer provided by the surface treatment layer adhesive consisting of hard material deposited in the preparative is characterized in that it is coated is provided.
[0006]
The operation and effect of the invention of claim 1 will be described. The surface treatment layer of the material to which the adhesive such as silicone is difficult to adhere on the release sheet is formed on the cover body by folding the cover body before the cover is used. By contacting the agent effective action area, the pressure sensitive adhesive in the adhesive effective action area is covered, so that it does not unintentionally contact the adhesive coating layer. When the cover is used, the folded portion of the cover body is opened, and the adhesive effective working area is exposed. Since the surface of the release sheet that has been in contact with the effective area of the adhesive has been subjected to a surface treatment with a material such as silicone that does not easily adhere to the adhesive, the adhesiveness of the adhesive in the effective area of the adhesive is from the initial state. There is virtually no damage. Then, the cover is applied to the seat with the release sheet attached and the adhesive effective action area opened, and the cover is attached to the seat by the adhesive force of the adhesive effective action area. When replacing, the cover is removed from the seat and discarded. When the cover is installed, the folded part is opened so that the adhesive effective action area is exposed, and it is attached to the seat with the adhesive in the adhesive effective action area. There is no waste associated with the cover. In addition, since a Velcro hook is not necessary on the seat side as in the conventional case, the total structure for mounting the cover is extremely simplified in combination with the simple structure of the cover itself, and a substantial reduction in cost can be realized. it can.
[0007]
According to the second aspect of the present invention, in the first aspect of the present invention, the adhesive layer of the pressure-sensitive adhesive is substantially separated from the adjacent edge of the cover body over substantially the entire width. There is provided a disposable cover characterized in that it is a non-adhesive part over its entire width.
[0008]
The action and effect of the invention of claim 2 will be described. Since the adhesive layer of the adhesive is separated from the adjacent edge of the cover body substantially over the entire width, the cover adjacent to the adhesive layer of the adhesive is provided. The part where the adhesive is not attached to the body edge side is formed in a belt shape, and this belt-like adhesive non-adhesion layer protrudes like a ridge when the cover body is folded. As a result, the adhesive layer is protected and the cover itself can be opened by turning over the heel when the cover is attached to a seat, etc., and a large number of covers can be attached as in the seats of aircraft and railway vehicles. In this case, workability can be improved.
[0009]
According to the invention described in claim 3, in the invention described in claim 1, in the folded state, the release sheet extends so as to slightly exceed the adhesive effective working area. A cover is provided.
[0010]
The action and effect of the invention of claim 3 will be described. In the folded state, since the release sheet extends so as to slightly exceed the adhesive effective action area, the adhesive effective action area may protrude to the outside. Therefore, the protection can be achieved, and the adhesive does not accidentally adhere to other parts.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1, a disposable cover according to the present invention includes a cover body 10 formed of a nonwoven fabric. Non-woven fabrics are made of natural fibers such as wood fibers or clothing fibers, recycled fibers such as rayon, synthetic fibers such as nylon or polyester, or composite fibers of these various fibers with or without a binder (adhesive). Or a web-like one that is entangled with each other by mechanical means such as a needle punch or hydrodynamic means such as air flow or water flow, by a wet method or a dry method, or various types such as spun bond and melt blow A method has been proposed, and in the present invention, it is possible to appropriately select and use an appropriate one available on the market by these known production methods. It goes without saying that the cover main body 10 must have a width and a length that can cover a covered portion such as an aircraft or a headrest of a vehicle seat with a margin.
[0012]
An adhesive coating layer 12 is formed in the vicinity of one end of the cover body 10 in the length direction. As an adhesive, an appropriate adhesive that does not detach the cover body 10 from a covered part such as an aircraft or a headrest of a vehicle seat in a normal use state but can be easily detached from the attached part by pulling the cover during replacement. A material that can stick with strength can be used. Suitable materials for such purposes include rubber-based materials, and for example, those obtained by emulsion polymerization of styrene rubber latex can be employed. That is, the adhesive is accommodated in the applicator, and the adhesive from the nozzle of the applicator is applied to the cover body 10 with a predetermined width, and the adhesive application layer 12 shown in FIG. 1 is formed. In this embodiment, the application of the adhesive coating layer 12 forms a narrow blank portion 10A (an uncoated layer of adhesive on the cover body 10) with respect to the edge 10-1 of the adjacent cover body 10. Has been done to be.
[0013]
In this way, the release sheet 14 is applied on the pressure-sensitive adhesive coating layer 12 formed on one side of the cover body 10. The release sheet is obtained by coating a release agent such as silicone on a base sheet such as kraft paper or polyester film. In this embodiment, the width of the release sheet 14 is somewhat larger than half of the pressure-sensitive adhesive coating layer 12. The release sheet 14 covered the adhesive coating layer 12 with the release coating surface 14-1 facing upward, covering almost half the width of the adhesive coating layer 12, and the other half of the area was exposed to the adhesive. It becomes the adhesive effective action region 12A (FIG. 2). Since the base material of the release sheet 14 remains exposed on the side 14-2 opposite to the coated surface 14-1, the pressure-sensitive adhesive coating layer 12 is in a strong adhesive state with respect to the exposed surface. FIG. 2 shows a state after the release sheet 14 is adhered. As shown in FIG. 2B, the release sheet 14 has a side edge 14A from the pressure-sensitive adhesive application layer 12 toward the edge 10-1 close to the cover body 10. It is arranged to protrude somewhat. The width of the release sheet 14 is approximately half that of the pressure-sensitive adhesive coating layer 12 in the embodiment of FIGS. 1 to 3, but the width of the release sheet is not limited to this. The attachment position in this case is shifted upward from (b) in FIG. 2, and the width of the adhesive effective action area 12A is increased by that amount. It is necessary to completely cover the release sheet 14 with the release agent coating surface 14-1.
[0014]
FIG. 3 shows a product form (unused state) as a cover according to the present invention. In the state where the release sheet 14 is attached to the adhesive coating layer 12 on the cover body obtained in FIG. Is folded along the inner edge of the release sheet 14. The release agent-coated surface 14-1 of the release sheet 14 is in contact with the pressure-sensitive adhesive effective action region 12A, but can be easily peeled, while the base material surface 14-2 of the release sheet 14 is firmly attached to the cover body 10. It is in a sticky state. And the edge part 10A of the cover main body 10 and the edge part 14A of the release sheet 14 extend somewhat beyond the adhesive coating layer 12, and the adhesive coating layer 12 is not directly exposed, thereby protecting it. be able to.
[0015]
Next, the mounting operation of the cover of the present invention on the seat headrest will be described. The product state of the cover is as shown in FIG. 3, and the cover main body 10 is folded along the inner edge of the release sheet 14. is there. Prior to the work, the cover body 10 is opened at the folded portion by pinching the edge 10A of the cover body 10, and at this time, the release agent coating surface 14-1 of the release sheet 14 is coated with the adhesive on the cover body 10. It peels easily from the layer 12, while the base material surface 14-2 of the release sheet 14 remains firmly adhered to the pressure-sensitive adhesive coating layer 12, and is in the same state as (b) of FIG. In FIG. 4, reference numeral 16 denotes a seat headrest portion to be covered, and the cover main body 10 is adhered to the back side of the headrest 16 in an adhesive effective action region 12 </ b> A as an adhesive exposed layer adjacent to the release sheet 14. Then, the remaining portion of the cover body 10 is routed around the tip portion of the headrest 16 and hangs down along the front surface portion of the headrest 16, thereby completing the mounting operation of the cover of the present invention. That is, in the present invention, the cover is attached to the seat headrest by opening the cover sheet 10 at one end of the cover body 10 so that the exposed portion of the adhesive (adhesive effective action region 12A) is adhered to the back surface of the headrest. The mounting is completed just by moving the remaining part around the headrest, and the release sheet 14 does not need to be peeled off when the cover is attached, so that the cover attaching operation is extremely simple, and no waste is produced when the cover is attached. The release sheet 14 can be discarded together with other parts when replacing the cover. In addition, since a conventional Velcro hook is not required for the seat as the mounted portion, and the cover structure itself is simple, a significant cost reduction can be realized as the total cover replacement cost.
