FLAT KEEPER

Technical Field

[1] The present invention relates, in general, to flat keepers having detachable parts, and, more particularly, to a flat keeper, in which a plurality of film sheets, each having an adhesive layer thereon and a predetermined size, is attached to a release liner having a predetermined size, so that, when required, the film sheet is adhered to an object surface after being detached from the release liner. Background Art

[2] Generally, in the conventional arts, in which film sheets, each having an adhesive layer, are detachably attached to a release liner, when required, the film sheets are detached from the release liner and, thereafter, adhered to an object surface. However, as such, in the case that the film sheet is detachably adhered to the release liner by a simple adhesion method, because the entire area of the film sheet is brought into close contact with the release liner by the adhesive layer, there is a disadvantage in that a user must peel the film sheet from the release liner using his/her fingers or detach it using a sharp tool. In a place where the keepers are used in large quantities, because the keepers are used in a state of being stacked, the keepers may become attached to each other by moisture or static electricity, thereby the film sheets may be undesirably removed from the release liners.

[3] Furthermore, after detaching the film sheet from the release liner, the user must hold the film sheet using his/her hand and attach it to an object surface. Therefore, the adhesive layer may be smeared with or damaged by foreign substances, so that the object surface, to which the film sheet is attached, may lose its clear finish. Disclosure of Invention Technical Problem

[5] Another object of the present invention is to provide a flat keeper in which, even if several keepers are laminated, due to connection points of each keeper that integrally connect a detachable liner to a release liner, the film sheet or the detachable liner is prevented from being undesirably removed from the release liner by moisture or static electricity, thus preventing the film sheets from becoming stuck and attached to each

other.

[6] A further object of the present invention is to provide a flat keeper which makes it possible to attach a detached film sheet to an object surface without damaging the film sheet and to provide a clear finish to the object surface, thus being convenient for the user.

[7] Yet another object of the present invention is to provide a flat keeper in which the detachable parts are oriented towards the center line of the flat keeper, thus being more convenient for the user to detach the film sheets. Technical Solution

[30] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[31] As shown in FIGS. 1 and 2, in a flat keeper 10 of the present invention, film sheets

20 are attached to a release liner 30 using respective adhesive layers 22 in a longitudinal or lateral direction, and a detachable part 40 is provided on each film sheet 20.

[32] The detachable part 40 comprises a detachable liner 31. To form the detachable liner 31, a cutting hole 34 is formed by cutting part of the release liner 30, and, thereafter, the release liner 30 is cut along a line crossing the opposite ends of the cut part of the release liner 30, with a contact edge 41 defined by the edge of the cutting hole 34 which is formed by cutting the release liner 30 along the line connecting the opposite ends of the cut part.

[33] Meanwhile, connection points 42a, at which the detachable liner 31 and the release liner 30 are coupled to each other, are provided on the contact edge 41 at regular intervals. The connection points 42a serve to hold the detachable liners 31, thus solving a problem in which, when several keepers 10 contact each other, the detachable liners 31 become separated from the film sheets 20 by moisture or static electricity, so that the laminated film sheets 20 become stuck and attached to each other.

[34] Furthermore, an additional connection point 42b is provided at a position spaced apart from a contact corner 43a, 43b, which is formed on each of the opposite ends of the contact edge 41, by a predetermined distance in an opening direction (in the direction indicated by the arrow A), thus more efficiently preventing the detachable liner 31 from being undesirably removed.

[35] The use of the above-mentioned embodiment of the present invention will be explained with reference to the drawings.

[36] Referring to FIGS. 3 through 5, a user puts his/her finger or the like into the cutting hole 34, which is formed at a predetermined portion through the release liner 30 and the film sheet 20, and pulls the detachable part 40 upwards. Then, the connection points 42, which have coupled the detachable liner 31 to the release liner 30, are cut, and, thereafter, the detachable liner 31 and the film sheet 20 are completely removed from the release liner 30. After the film sheet 20 is removed from the release liner 30,

the film sheet 20 is oriented, such that the adhesive layer 22 faces an object surface 51. Subsequently, the film sheet 20 is adhered to the object surface 51 in a direction moving from a portion opposite the detachable part 40 towards the detachable part 40.

[37] Thereafter, the detachable liner 31, which has been attached to the film sheet 20, is removed from the film sheet 20 and, simultaneously, the film sheet 20 is completely adhered to the object surface 51. As such, the film sheet 20 can remain clear while adhering to the object surface 51 without the adhesive layer 22 being damaged by foreign substances.

[38] According to another embodiment of the present invention, as shown in FlG. 6, a detachable part 40' has a triangular shape formed by cutting a part of a release liner 30' along the outer edge of a corner of each rectangular film sheet 20' and by cutting the release liner 30' along a line crossing the opposite ends of the edge of the cut part. Furthermore, connection points 42a' are provided on a contact edge 41' of the cut part at regular intervals.

[39] According to a further embodiment of the present invention, as shown in FlG. 7, each film sheet 20" has a circular shape. A detachable part 40" has a bow shape formed by cutting part of a release liner 30" along part of an outer edge of the film sheet 20" and by cutting the release liner 30" along a line crossing opposite ends of the outer edge of the cut part of the release liner. Furthermore, connection points 42a" are provided on a contact edge 41" of the cut part at regular intervals.

[40] According to other embodiments, as shown in FIGS. 8 through 10, film sheets 20,

20', 20" are attached to and arranged on a release liner 30, 30' 30" in rows such that detachable parts 40, 40' 40", which are provided in the film sheets 20, 20', 20" disposed at left and right sides, face each other. In other words, the film sheets 20, 20', 20" are arranged such that, when the user folds the release liner 30, 30' 30" along an arbitrary longitudinal folding line 35, which is formed between the left and right film sheets 20, 20', 20", the detachable parts 40, 40' 40" face the same direction. Then, the user can more conveniently detach the detachable liner 31 and the film sheets 20, 20', 20" from the release liner 30.
