Clip device for two flaps of boxes

A clip device includes a first board with a T-shaped connection plate extending from a first surface thereof. The T-shaped connection plate includes a first plate extending vertically from the first surface of the first board and a second plate is connected on a top edge of the first plate. A second board has a groove defined in a first surface thereof and two receiving spaces are defined in the groove. The second plate is engaged with one of the two receiving spaces of the groove. Two flaps of a box are received in two sides of the clip device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2 , the clip device 10 of the present invention comprises a first board 20 having a T-shaped connection plate extending from a first surface thereof and a second board 40 is connected to the T-shaped connection plate. The T-shaped connection plate includes a first plate 30 extending vertically from a central axis of the first surface of the first board 20 and a second plate 31 is connected on a top edge of the first plate 30 so as to form the T-shaped structure. The second board 40 has a groove 41 defined in a first surface thereof and two separation ridges 42 respectively extend from two opposite insides of the groove 41 so as to define two receiving spaces 411 , 412 in the groove 41 by the separation ridges 42 . The second plate 31 can be engaged with one of the two receiving spaces 411 , 412 and two side slots 50 are respective defined in two lateral sides of the clip device 10 . As shown in FIGS. 3 and 4 , two flaps 61 of a box 60 are respectively slid into the two side slots 50 of the clip device 10 and the clip device 10 can be slid to a desired position of the box 60 . The second plate 31 can be received in the receiving space 412 so as to narrow the width of the side slots 50 as shown in FIG. 5 such that thin flaps can also be properly received in the side slots 50 . As shown in FIGS. 6 and 7 , the first board 20 and the second board 40 each have two recesses 21 / 43 defined in two sides thereof so that the user's fingers are conveniently engaged with these recesses 21 , 43 to move the clip device 10 . As shown in FIGS. 8 , the first surface of the first board 20 includes two inclined surfaces which are separated by the T-shaped connection plate. By the inclined surfaces, the opening of the two side slots 50 are narrower and may hold the flaps securely. As shown in FIG. 9 , the first surface of the first board 20 includes two convex surfaces which are separated by the T-shaped connection plate. The first surface of the second board 40 includes two convex surfaces which are separated by the groove 41 . By the convex surfaces, the mediate portion of the side slots 50 are narrowed to clip the flaps. FIG. 10 shows that the first board 20 and the second board 40 each have two inclined surfaces so that the side slots 50 have a narrow opening. While we have shown and described the embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
