DETAILED DESCRIPTION OF THE INVENTION

(9) The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.

(10) Where the terms about or generally are associated with an element of the invention, it is intended to describe a feature's appearance to the human eye or human perception, and not a precise measurement, or typically within 10 percent of a stated value.

(11) FIG. 1 is a frontal perspective view of a tissue box. FIG. 2 is a rear perspective view of the tissue box and FIG. 3 is an exploded view of the tissue box.

(12) FIGS. 1 through 3, show the tissue box (100), according to the present invention, has a rectangular cuboid shape like a tissue box and a pull-out-port (51) through which the tissue pulls out in the upper center. Inside the tissue box (100), a predetermined number of tissues are stacked and stored in an overlap-folded state.

(13) A horizontal fold line (11) is formed on the front surface (10) of the tissue box (100) below the middle height, and at both ends where the horizontal fold line (11) ends, vertical perforation lines (12) are formed along corners below the fold line (11). A preferred fold line (11) is a line with intermittent cuts so that the user can easily bend it by hand; the perforation lines (12) are cut at regular intervals so that the user can easily tear it by hand. A tissue window (15) is provided on the upper portion of the horizontal fold line (11) formed on the front surface (10) of the cosmetic tissue box (100), and the tissue window (15) has cutouts extending vertically. It is possible to monitor the remaining amount of the tissues stored inside the tissue box (100). In an embodiment of the present invention, a transparent film such as vinyl is attached to the inside of the cutout of the tissue window (15) to prevent direct contact between the tissues and the exterior of the tissue box (100).

(14) A horizontal fold line (21) forms on the rear surface (20) at the same height as the horizontal fold line (11). And at both ends of the horizontal fold lines (11) and (21), vertical perforation lines (12) and (22) form along the edges below the horizontal fold lines (11) and (21). In addition, horizontal fold lines (31) and (41) form at the same height as horizontal fold lines (11) and (21) on the left end surface (30) and the right end surface (40) of the tissue box (100).

(15) On the bottom surface (60) of the tissue box (100), a horizontal perforation line (61) is formed in the middle in the lengthwise direction, and two end perforation line (62) are formed along the edges at both ends of the horizontal perforation line (61). Two pairs of locking keys (65) are incorporated on the bottom surface (60) so that the folded ends of the left end surface (30) and the right end surface (40) may tuck in. In the present invention, the cut-out shape of the lock key (65) is in the pattern of a U.

(16) The tissue box (100), configured above, would allow the decrease of its height by folding along fold lines and perforation lines formed on the box surfaces when the user pulls out enough tissues stored inside and the residual tissue observed through the tissue window (15) is less than half.

(17) FIG. 4 shows the process of reducing the height of the tissue box (100). The process is as follows: First, as shown in FIG. 4 (a), the tissue box (100) is turned upside down; the tissue stored inside sinks to the bottom by gravity, causing the underside of the bottom surface (60) remains more than half empty. Then, as shown in FIG. 4 (b), the horizontal perforations line (61), and the vertical perforation lines (12) and (22) are cut and spread open. Then, as shown in FIGS. 4 (c) and (d), fold along the horizontal fold lines (11) and (21); the folded parts are the cut-out front surface (10) and the cut-out surface of the bottom surface (60) extending from front surface (10), and the cut-out rear surface (20) and the cut-out surface of the bottom surface (60) extending from (20). The two folded faces overlap one on top of the other, as shown in FIG. 4(d).

(18) As shown in FIG. 4 (e) and (f), the left end surface (30) and the right end surface (40) are folded inward of the box along the fold lines (31) and (41); the ends of the folded surfaces are tucked under the lock keys (65) to finish the modification of the box.

(19) When the tissue box (100) reassembled through the above procedures is turned upside down, a new tissue box (100) with a reduced box height emerges, as shown in FIG. 5.

(20) FIG. 6 shows an example of an exploded view of a tissue box with code numbers according to an embodiment of the present invention. The modification of the height of the tissue box (100) entails folding and cutting the surfaces of the box. The dimensional relation is shown in equation 1 as follows: Equation 1:
e=a+c
b=f??
d=c

(21) Here, (e) is the height of the front surface (10) and the rear surface (20), (a) is the length (or height) of the portion (40a) connected to the top surface (50) and folded to form a part of the left end surface (30) or the right end surface (40). (c) is the length (or height) of the portion (40b) that connects to the bottom surface (60) and folds to form a part of the left end surface (30) or the right end surface (40); accordingly, the sum of the lengths (a) plus (c) is equal to the length of (e). That is, the lengths of the folded portions 40a and 40b are combined (a+c) to become the height (e) of the front surface (10) and the rear surface (20).

(22) In addition, (f) is the width of the top surface (50) and the bottom surface (60); (b) is the length of a folded portion 20a at the ends of the back surface 20 and the length of a folded portion 10a at the ends of the front surface 10, (c) is the length of the portion (30b) which is a part of the left end (30) and the portion (40b) which is part of the right end (40) connected to the front surface (10) and the back surface (20) and folded respectively. The length (b) is % of the width (f) of the upper surface (50) and the bottom surface (60). (d) is the distance measured from the bottom surface (60) to the horizontal fold lines (11) and (21), and the length is the distance from the vertical perforation line (62) of the bottom surface (60) to the lock key (65).

(23) Meanwhile, the height (d) of the horizontal fold lines (11) and (21) formed on the front surface (10) and the rear surface (20) satisfies the following equation.
d=??f, if e>f
d=??e, if e=fEquation 2

(24) As in equation 2, in the present invention, the magnitude of (d) may vary depending on the width (f) and the height (e).

(25) The front surface (10) and rear surface (20) fold along the horizontal fold lines (11) and (21) to form a new bottom surface. The new bottom surface (60) is in two layers. The left end surface (30) and the right end surface (40) fold along the horizontal fold lines (31) and (41). And the ends of the folded surface are tucked under the lock keys (65) formed on the bottom surface (60).

(26) As such, in the present invention, horizontal fold lines (11), (21), (31), (41), and vertical perforation lines (12), (22), (32), (42), and (62) are formed on the tissue box surfaces. By cutting and folding along the perforations and folding lines, the height of the tissue box may be reduced; and solve the problem that the tissues do not come up in a cascade up to the last sheet of tissue.

(27) On the other hand, the present invention is not limited to the above-described embodiments, and various modifications may be possible by those of ordinary skill in the technical field to which the present invention pertains within the scope of equivalents of the technical spirit of the present invention and the claims to be described below. And, of course, modifications may be made.
