Therefore, it is prevented from being pushed or folded in the process of cutting the film F by the cutter 140.

The operation of the first embodiment of the wrap case with the above-described cutting slide will now be described.

5 is a front sectional view of a wrap case with a slide for cutting according to the present invention, FIG. 6 is a side view of a wrap case with a slide for cutting according to the present invention, and FIG. 7 is a wrap with a slide for cutting according to the present invention 8 is a cross-sectional view taken along line AA ′ of FIG. 6, FIG. 9 is an enlarged cross-sectional view of a portion “B” of FIG. 7, and FIG. 10 is a cross-sectional view taken along line C-C ′ of FIG. 9.

5 to 7, in a state where the film roll R is accommodated in the inner accommodating space 111 of the case body 110, the film F which is unwound from the film roll R is the case body. It is discharged to the outside through the outlet hole 112 of the 110, the opening of the receiving space 111 of the case body 110 by the cover 120 is rotatably coupled to one side of the case body (110) It is selectively opened and closed.

The film roll R accommodated in the case main body 110 is inserted in a rotatable state by a support 117 inserted into and fastened to the through holes 116 provided at both sides of the case main body 110, and the film roll R The inner circumferential surface of R is supported by the support 117a of the support tool 117. Therefore, the support 117 is easily inserted into the paper pipe of the film roll R, and the play of the film roll R supported by the support 117 is minimized.

Subsequently, in the state in which the cover 120 is closed, the side wall portions 121 provided on both sides of the cover 120 are disposed to surround the outer surface of the support 117 on both sides of the case body 110, thereby supporting the supporter ( 117 may be prevented from being arbitrarily separated from the case body 110.

Further, when the guide groove 131 of the slide 130 is coupled to the guide rail 113, the slide 130 is located at the end of the guide rail 113 of the side on which the locking step 113a is formed, the guide Since the periphery of the groove 131 is caught by the locking jaw 113a, the movement is restricted, so that the slide 130 is prevented from being separated from the guide rail 113. At the opposite end of the guide rail 113, when the stopper 118 is coupled to the coupling hole 113b of the case body 110, the slide 130 is moved by the stopper 118 like the locking step 113a. This is limited, and it becomes possible to separate the slide 130 from the guide rail 113 in a state where the stopper 118 is removed from the coupling hole 113b. Therefore, in the state in which the stopper 118 is separated from the coupling hole 113b, the slide 130 becomes detachable from the guide rail 113, so that the user can easily replace the slide 130 or separate for maintenance. It becomes possible.

In addition, the grooves 114 for cutting the film F and the guide rails 113 for guiding the movement of the slide 130 while the cutter 140 moves are arranged side by side. That is, the cutter provided in the other end of the slide 130 in the process of the guide groove 131 formed at one end of the slide 130 is coupled to the guide rail 113 formed on the outer surface of the case body 110 to move ( Since the 140 is configured to cut the film (F), as well as the stable movement of the slide 130, as well as easy to press the slide 130 for cutting the film (F), it provides an easy to use advantage .

Meanwhile, the film F drawn out to the outside through the drawing hole 112 of the case body 110 moves along the guide rails 113 disposed at one side of the drawing hole 112. In the process of traversing the film (F) is cut by the cutter 140 provided on the slide 130 side. Therefore, the user can easily cut the film F by drawing the film F to a desired length, and then holding the slide 130 and moving it in the transverse direction.

Looking at the cutting process of the film (F) is as follows.

First, as shown in FIG. 8, the slide 130 has a guide groove 131 at one end thereof engaged with the guide rail 113 of the case body 110 to move along the guide rail 113, and the guide rail ( 113 and the front end portions of the guide groove 131 are bent and engaged with each other, thereby preventing the guide groove 131 of the slide 130 from being arbitrarily separated from the guide rail 113 in the moving process.

In addition, since the support shaft 133 penetrating the cutter 140 and the pressing means 150 disposed on both sides of the cutter 140 are coupled to the support 132 formed at the other end of the slide 130, In the process of the user holding the slide 130, the cutter 140 and the pressing means 150 is moved with the slide 130.

In this case, the cutter 140 is cut in the process of passing the upper side of the film (F). In particular, in the process of cutting the film F, the pressing means 150 respectively disposed on both sides of the cutter 140 presses both sides of the cut portion of the film F toward the case body 110, so that the film ( The cutting portion of F) is prevented from being pushed forward or folded by contacting the cutter 140, thereby smoothly cutting.

In particular, as shown in FIGS. 9 and 10, the pressing means 150 respectively disposed on both sides of the cutter 140 is rotatable on the support shafts 133 disposed respectively at the front and the rear of the cutter 140. Since the pressing belt 152 is wound on the outside of the pair of rotating rollers 151 to be installed, when the slide 130 moves, the pair of rotating rollers 151 wound by the pressing belt 152 rotate. As a result, the pressing belt 152 is maintained in the surface contact state with the film (F).

Therefore, in the process of cutting the film F in contact with the cutter 140 when the slide 130 moves, both sides of the film F in contact with the cutter 140 are supported by the pressing means 150. Since the state supported by the pressing means 150 is continuously maintained until the front region of the portion in contact with the cutter 140 is cut, the film (in the cutting process of the film F by contact with the cutter 140) F) is prevented from being pushed or folded in the cutting direction.

In addition, the cutter 140 cuts the film F because the blade 142 is inclined in a state where the through hole 141 formed on the plate surface is fixed to the slide 130 by a pair of support shafts 133. In addition to this easily, since the blade 142 is disposed on both sides of the lower end, it is possible to cut the film (F) for the bidirectional movement of the slide (130).

The cutter 140 is accommodated in the groove 114 of the case body 110 formed concave at a position corresponding to the cutter 140 to prevent damage to the blade 142, the film 114 on both sides of the groove 114 The close contact portion 115 for increasing the contact friction with F) is formed. The close contact portion 115 may smoothly process the surfaces of both sides of the groove 114 of the outer surface of the case body 110 to easily adhere the film (F) such as a wrapping wrap, An elastic pad of rubber material having elasticity may be disposed to closely adhere the film F such as a paper foil. On the other hand, although not shown in the drawing, when placing the elastic pad of rubber material having elasticity it would be desirable to separately provide a fixing groove for fixing the elastic pad on both sides of the groove 114.

On the other hand, although not shown in the drawings, the outer circumferential surface of the rotary roller 151 and the inner circumferential surface of the pressing belt 152, respectively, by forming an uneven portion to engage with each other by the front rotary roller 151 and the rear rotary roller 151 is interlocked. It would be possible to do so.
