Description

SHOCK- ABSORBING MEMBER FOR PACKING AND PAPER SHEET FOR FORMING THE SHOCK-ABSORBING MEMBER, PACKING UNIT AND PACKING METHOD FOR PACKING ELECTRONIC PRODUCTS USED THE SHOCK-ABSORBING MEMBER, AND ELECTRONIC PRODUCT PACKED BY THE

PACKING METHOD Technical Field

[1] The present invention relates to product packing, and more particularly, to a shock- absorbing member for packing which is capable of supporting and protecting a product in a package and a paper sheet to realize the shock-absorbing member, a product packing unit using the shock-absorbing member and a packing method, and an electronic product packed by the packing method. Background Art

[2] As well known, electronic products, such as a laptop computer, a camcorder, a compact audio device, a digital camera, a PDA, a game machine, an electronic dictionary, a mobile phone, and a CCTV camera, are susceptible an inner shock, and, thus, when such electronic products are packed, it is necessary to use a shock- absorbing member to absorb a shock transmitted to a packing box.

[3] A representative example of the shock-absorbing member for packing is an expended poly stylene (EPS), which is also called Styrofoam. However, if the product is relatively compact like a camcorder, a compact audio device, a digital camera, a CCTV camera, a game machine, and a mobile phone, and if it also includes various accessories such as cable, the EPS shock-absorbing member occupies a large packing space unnecessarily, which increases a packing volume. Furthermore, there has been a decline in consumption of EPS because it pollutes environment and it is difficult to process a waste EPS, and in some nations, the use of EPS is strictly restricted.

[4] A paper shock- absorbing member using a corrugated cardboard in place of the EPS is used. However, such a paper shock-absorbing member is assembled and manufactured according to an appearance of a product to be packed, and thus, it is bulky. Therefore, it is inconvenient to transport or maintain the shock-absorbing member. Recently, the shock-absorbing member is transported in an unfolded state and then is assembled into a complete folded shock-absorbing member when packing a product on a packing line. However, it is difficult to assemble the shock-absorbing member and also additional processes such as gluing are required. Accordingly, much time is required.

Also, the 3^rd and the 4^th lateral sections C, C have 2 n^d lateral shock-absorbing sections D, D' partitioned by 3^rd and 4^th folding lines cl, c2 along opposite sides thereof. The 1^st and 2^nd lateral sections B, B' have the same lengths Ll as those L2 of the 2^nd lateral shock-absorbing sections D, D¹ and accordingly, the paper sheet 1 is shaped in a rectangle as a whole.

[38] The bottom section A has 5^th and 6^th folding lines dl, d2 to form a bottom shock- absorbing part 10a, and the 1^st lateral section B has 7^th and 8^th folding lines el, e2 to form a lateral shock-absorbing part 20a. The 7^th and 8^th folding lines el, e2 are arranged at the same interval as that of the 5^th and 6^th folding lines dl, d2. The 2^nd lateral section B has 9^th and 10^th folding lines fl, f2 to form another lateral shock- absorbing part 20'a. However, the 9^th and 10^th folding lines fl, f2 are arranged at a different interval from that of the 5^th and 6^th folding lines dl, d2. The 5^th through 10^th folding lines dl, d2, el, e2, fl, f2 are arranged at appropriate intervals according to appearance and weight of a product to be packed.

[39] 1^st cut-off parts E, E¹ are formed around the 1^st folding lines al, a2 between the bottom section A and the 1^st and the 2^nd lateral sections B, B' i.e., around a boundary between the bottom shock- absorbing part 10a and the lateral shock-absorbing parts 20a, 20'a. Lengthwise widths Wl of the 1^st cut-off parts E, E' are equal to a width W2 of the bottom shock-absorbing part 10a.

[40] Widths W3 of the 1^st and the 2^nd lateral sections B, B' are wider than a width W4 of the bottom section A, and widths W5 of the 2^nd lateral shock-absorbing sections D, D' are narrower than widths W6 of the 3^rd and the 4^th lateral sections C, C Also, 2^nd cut-off parts F, F¹ are formed around boundaries between the 1^st and the 2^nd lateral sections B, B' and the 2^nd lateral shock-absorbing sections D, D' Opposite sides of each of the 1^st and the 2^nd lateral sections B, B' are rounded R in the proximity of the first folding lines al, a2.

[41] The paper sheet 1 for forming the shock-absorbing member for packing according to the exemplary embodiment of the present invention is prepared by placing a raw material such as a corrugated cardboard on a press die, to which a structure for forming the bottom shock-absorbing part 10a, the lateral shock-absorbing parts 20a, 20'a, and the cut-off parts E, E¹ F, F¹ is applied, and pressing down it with a punch. The punch is provided with, for example, a tool to cut along an external line of the paper sheet 1 and a tool to form the 1^st through the 10^th folding lines al, a2, bl, b2, cl, c2, dl, d2, el, e2, fl, f2, thereby preparing the paper sheet 1 as shown in FIG. 1. Through this pressing process, a mass production of the paper sheet 1 according to the exemplary embodiment of the present invention is possible.

[42] The 1^st through 4^th lateral sections B, B' C, C are folded inwards along the 1^st and 2^nd folding lines al, a2, bl, b2 of the paper sheet 1, and the 2^nd lateral shock- absorbing sections D, D' are folded outwards along the 3^rd and 4^th folding lines cl, c2. Consequently, the paper sheet 1 is assembled into a shock-absorbing member 100 for packing, which can protect and support five surfaces of a product to be packed except for an upper surface, as shown in FIGS. 2 and 3.

[43] Thickness of paper such as a corrugated cardboard used as a raw material for the paper sheet 1 is appropriately chosen in consideration of type, weight, and size of a product to be packed.

[44] Hereinafter, the shock-absorbing member 100 according to the exemplary embodiment of the present invention will be described with reference to FIGS. 2 through 5. In this embodiment, a CCTV camera 200 will be described as a product to be packed as shown in FIG. 7 by way of an example. Also, hereinafter, a lens side of the CCTV camera 200 is referred to as a front surface and the opposite side is referred to as a rear surface. The opposite sides of the CCTV camera 200 are referred to as left and right surfaces. If it is difficult to distinguish the four sides of a product to be packed, the front and the rear surfaces, the right and left surfaces, and the bottom are referred as 1^st through 5^th surfaces.

[45] As shown in FIGS. 2 and 3, the shock-absorbing member 100 for packing according to the exemplary embodiment of the present invention includes a bottom 10, front and rear surfaces 20, 20' bent from front and rear sides of the bottom 10 in a substantially vertical direction, and left and right surfaces 30, 30' bent from left and right sides of the bottom 10 in a substantially vertical direction.

[46] Also, the shock- absorbing member 100 according to the exemplary embodiment of the present invention includes a bottom shock- absorbing part 10a which is formed by bending up a part of the bottom 10, a front shock-absorbing part 20a which is formed by bending a part of the front surface 20 inwards, a rear shock-absorbing part 20'a which is formed by bending a part of the rear surface 20' inwards, a pair of left shock- absorbing parts 30a which is formed by folding opposite side ends of the left surface 30 outwards, and a pair of right shock-absorbing parts 30'a which is formed by folding opposite side ends of the right surface 30'outwards.

[47] The bottom shock-absorbing part 10a is formed by bending a part of the bottom 10 upwards to a predetermined height 'h¹ by folding it along the 5^th and 6^th folding lines dl, d2. According to this configuration, as shown in FIG. 5, a shock-absorbing space Sl is formed between a bottom 310 of a packing box 300 and the bottom shock- absorbing part 10a.

[48] The front shock-absorbing part 20a is formed by bending a part of the front surface

20 inwards by folding it along the 7^th and the 8^th folding lines el, 62, and the rear shock-absorbing part 20'a is formed by bending a part of the rear surface 20' inwards by folding it along the 9^th and the 10^th folding lines fl, f2. According to this configuration, as shown in FIG. 6, predetermined shock- absorbing spaces S2, S3 are formed between the front and the rear surfaces 320, 320 of the packing box 300 and the front and the rear shock-absorbing parts 20a, 20'a.

[49] The cut-off parts E, E' are formed between the bottom shock- absorbing part 10a and the front and the rear shock-absorbing parts 20a, 20'a such that the shock-absorbing parts 10a, 20a, 20'a interfere with one another if the front and the rear surfaces 20, 20' are folded in a vertical relation to the bottom 10. Shorter side widths W7 of the cut-off parts E, E' is greater than the height 'h' of the bottom shock-absorbing part 10a (see FIG. 5).

[50] The left and the right shock-absorbing parts 30a, 30'a include 1^st and 2^nd elastic flaps

31, 32, 31' 32' which are folded outwards along the 3^rd and 4^th folding lines Cl, C2 formed along opposite side ends of the left and the right surfaces 30, 30' If the 1^st elastic flaps 31, 31' are folded in a vertical relation to the left and the right surfaces 30, 30' and then the 2^nd elastic flaps 32, 32' are folded parallel to the left and the right surfaces 30, 30' predetermined shock-absorbing spaces S4, S5 are formed between the left and the right surfaces 30, 30' and the left and the right surfaces 330, 330' of the packing box 300 as shown in FIG. 5. In these shock-absorbing spaces S4, S5, an accessory 210 (e.g. a connection cable) of an electronic product to be packed is received as shown in FIG. 7. That is, the shock-absorbing spaces S4, S5 are used as an accessory receiving space. Herein, the 2^nd elastic flap 32 is longer than the 1^st elastic flap 31 but this should not be considered as limiting.

[51] The front and the rear surfaces 20, 20' include support flanks 21, 21' extending from their opposite side ends. The support flanks 21, 21' is overlaid with the first elastic flaps 31, 31 ' of the left and the right surfaces 30, 30' as the left and the right surfaces 30, 30' are folded and then the front and the rear surfaces 20, 20' are folded, thereby supporting the front and the rear surfaces 20, 20' The support flanks 21, 21' have lower side rounded so that the assembled shock- absorbing member 100 can be smoothly inserted into the packing box 300. Of course, the front and the rear surfaces 20, 20' are separated from the elastic flaps 32, 32' of the left and the right shock-absorbing parts 30a, 30'a due to the 2^nd cut-off parts F, F'(see FIG. 1).

[52] The shock-absorbing member 100 which is assembled from the paper sheet 1 according to the exemplary embodiment of the present invention is inserted into the packing box 300 as shown in FIG. 4. Hereinafter, a product packing unit according to the exemplary embodiment of the present invention will be described with reference to FIGS. 4 and 7.

Also, additional shock-absorbing spaces are formed between the left and the right surfaces 30, 30' of the shock-absorbing member 100 and the left and the right surfaces 330, 330' of the packing box 300 due to the left and the right shock-absorbing parts 30a, 30'a.

[54] As described above, after the shock- absorbing member 100 is inserted into the packing box 300, an electronic product 200 (CCTV camera in the drawings) is placed on a main receiving part of the shock-absorbing member 100. Then, the bottom of the electronic product 200 is supported by the bottom shock- absorbing part 10a of the shock-absorbing member 100, the front of the electronic product 200 i.e. the lens unit is supported by the front shock-absorbing part 20a of the shock-absorbing member 100, and the rear of the electronic product 200 is supported by the rear shock- absorbing part 20'a of the shock- absorbing member 100. In the same way, the left and the right of the electronic product 100 are supported by the left and the right shock- absorbing parts 30a, 30'a of the shock-absorbing member 100. That is, one integral type paper shock- absorbing member 100 is folded into a box with an opened upper end, and, stably supports the five surfaces of the electronic product 200 except for the upper surface.

2^nd cut-off parts which are formed around boundaries between the 1^st and the 2^nd lateral sections and the 2^nd lateral shock-absorbing sections, wherein the 1^st through the 4^th lateral sections are folded inwards along the 1^st and the 2^nd folding lines and the 2^nd lateral shock-absorbing sections are folded outwards along the 3^rd and the 4^th folding lines, thereby forming a box-type shock-absorbing member to protect and support five surfaces of a product to be packed except for an upper surface.

[14] The paper sheet as claimed in claim 13, shaped in a rectangle in which lengths

Ll of the 1^st and the 2^nd lateral sections are equal to lengths L2 of the 2^nd lateral shock-absorbing sections.

[15] The paper sheet as claimed in claim 14, wherein widths W3 of the 1^st and the 2^nd lateral sections are wider than a width W4 of the bottom section, and opposite sides of each of the 1^st and the 2^nd lateral sections are rounded in the proximity of the 1^st folding lines.

[16] The paper sheet as claimed in claim 13, wherein the bottom section has 5^th and 6^th folding lines to form the bottom shock-absorbing part, the 1^st lateral section has 7 t^h and 8^th folding lines arranged at the same interval as that of the 5^th and the 6^th folding lines to form a lateral shock-absorbing part, and the 2^nd lateral section has 9^th and 10^th folding lines arranged at a different interval from that of the 5^th and the 6^th folding lines to form another lateral shock-absorbing part.

[17] A product packing unit, comprising: a packing box; and the shock-absorbing member for packing according to any one of claims 1 through 12 which protects and supports five surfaces of a product to pack except for an upper surface.

[18] A method for packing a product, the method comprising: preparing a packing box; assembling the paper sheet according to any one of claims 13 through 16, thereby forming a shock- absorbing member for packing; inserting the shock-absorbing member into the packing box; placing a product body in a space which is defined by a bottom and 1^st through 4 ^ lateral surfaces of the shock-absorbing member and placing a product accessory in a space which is defined between the 3^rd and the 4^th lateral surfaces of the shock-absorbing member and corresponding lateral surfaces of the packing box; closing an inner cover formed on the packing box and placing a product service manual on the inner cover; and closing and locking an outer cover formed on the packing box.

[19] An electronic product packed by the packing unit according to claim 17.

[20] An electronic product packed by the packing method according to claim 18.
