Here, the first product 400 can be a small product such as a mobile phone.

[0023] The outer shell 110 may be in the form of a tube having a certain length and open on one side.

[0024] The outer skin 110 can be formed to a length suitable for application as a hand strap for the first product 400 and can house the inner skin 120 .

[0025] The outer skin 110 may be made of a material such as, but not limited to, a thin cloth.

[0026] The inner skin 120 may be contained within the outer skin 110, and when the inner skin 120 is unfolded, it may be in the form of a shopping bag with one side open.

[0027] The inner skin 120 may be made of a material such as, but not limited to, a thin cloth or a non-woven fabric.

[0028] The strap-combined shopping bag 100 becomes a handy strap for the first product 400 when the inner layer 120 is housed in the outer layer 110 described above, and becomes a shopping bag in which items can be placed when the outer layer 110 is slid and the inner layer 120 is pulled out and unfolded.

[0029] The outer skin 110 and the inner skin 120 may be of one piece, with the other side of the outer skin 110 and the other side of the inner skin 120 fixed together.

[0030] The inner skin 120 may be formed such that the length from one side to the other side is at least longer than the length from one side to the other side of the outer skin 110. Thus, when the inner skin 120 is housed in the outer skin 110, one side of the inner skin 120 may partially protrude from one side of the outer skin 110 to the outside.

[0031] The shopping bag 100 with strap according to the first embodiment of the present invention may further include a first buckle 130 , a first snap button 140 , a second snap button 150 , a handle 160 , and a shape-retaining ring 170 .

[0033] The first buckle 130 can be a female buckle or a male buckle, and the second buckle 410 can be a male buckle or a female buckle opposite to the first buckle 130. In this embodiment, the means for connecting the strap-type shopping bag 100 and the first product 400 is described as a buckle, but is not limited thereto.

[0034] The first snap button 140 may be attached to one side of the inner shell 120 that partially protrudes outward from one side of the outer shell 110 .

[0035] The second snap button 150 can be attached to a portion where the other side of the outer skin 110 and the other side of the inner skin 120 are fixed, and is detachable from the first snap button 140 .

[0036] The first snap button 140 mentioned above can be a female snap button or a male snap button, and the second snap button 150 can be a male snap button or a female snap button opposite to the first snap button 140 .

[0037] The handle 160 may be formed by cutting a part of the inner leather 120 on the opposite side to the part of the inner leather 120 to which the first snap button 140 is attached.

[0038] The shape-retaining ring 170 may be attached to the inlet of one side opening of the outer shell 110 .

[0039] When the strap-combined shopping bag 100 configured as described above is used as a handy strap for the first product 400 by using the outer layer 110 and the inner layer 120 as the outer layer 110, the first buckle 130 is connected to the second buckle 410 attached to the first product 400 with the inner layer 120 housed in the outer layer 110, and the first snap button 140 is connected to the second snap button 150.

[0040] In addition, when using the inner layer 120 of the shopping bag 100 with strap as a shopping bag, the first buckle 130 and the second buckle 410 and the first snap button 140 and the second snap button 150 are separated, and the outer layer 110 is slid using the shape retention ring 170 to pull out the inner layer 120.

[0041] Thereafter, when the strap combined shopping bag 100 that has been used as a shopping bag is to be reused as a handy strap for the first product 400, the above-mentioned steps may be carried out in reverse order.

[0042] The process in which the strap-combined shopping bag 100 according to the first embodiment of the present invention, configured as described above, is transformed from the handy strap of the first product 400 into a shopping bag is shown in Figures 5(a), (b), (c), and (d).

[0049] The inner skin 220 may be housed in a shape-retaining ring 260, and when the inner skin 220 is unfolded, it may be in the form of a shopping bag with one side open.

[0050] The inner skin 220 can be made of a material such as, but not limited to, a thin cloth or a non-woven fabric.

[0051] The strap-combined shopping bag 200 becomes a handy strap for the first product 400 when the inner layer 220 is housed in the shape-retaining ring 260 described above, and can become a shopping bag in which items can be placed when the shape-retaining ring 260 is slid to pull out and unfold the inner layer 220.

[0052] The shape-retaining ring 260 and the inner skin 220 may be of an integral type in which the other side of the shape-retaining ring 260 and the other side of the inner skin 220 are fixed to each other.

[0053] The inner skin 220 may be formed such that the length from one side to the other side is at least longer than the length from one side to the other side of the shape-retaining ring 260. Thus, when the inner skin 220 is housed in the shape-retaining ring 260, one side of the inner skin 220 may partially protrude outward from one side of the shape-retaining ring 260.

[0054] The shopping bag with strap 200 according to the second embodiment of the present invention may further include a handle 230, an extension 240, a first buckle 250, and a shape maintaining ring 260.

[0055] The handle 230 may be formed at a portion that protrudes outward from one side of the outer shell 210. The handle 230 protrudes outward and extends a certain length, so that when the strap-combined shopping bag 200 is used as a handy strap for the first product 400, the length of the handy strap is further extended.

[0056] The extension portion 240 is a portion formed by extending a certain length of the outer cover 210 from the portion where the other side of the outer cover 210 and the other side of the inner cover 220 are fixed, thereby further extending the length of the handy strap when the strap-combined shopping bag 200 is used as a handy strap for the first product 400.

[0057] A pair of the first buckles 250 may be attached to each of the handle 230 and the end of the extension 240 of the outer skin 210. When the outer skin 210 and the inner skin 220 are used as a handy strap for the first product 400, such a pair of first buckles 250 may be overlapped and coupled to the second buckle 410 attached to the first product 400 with the inner skin 220 housed in the outer skin 210.

[0058] The first buckle 250 can be a female buckle or a male buckle, and the second buckle 410 can be a male buckle or a female buckle opposite to the first buckle 250. In this embodiment, the means for connecting the strap-type shopping bag 200 and the first product 400 is described as a buckle, but is not limited thereto.

[0059] The shape-retaining ring 260 may be attached to the inlet of one side opening of the outer shell 210 .

[0060] When the strap-combined shopping bag 200 configured as described above is used as a handy strap for the first product 400 by using the outer cover 210 and the inner cover 220 as the outer cover 210 and the inner cover 220 housed therein, the pair of first buckles 250 are overlapped and connected to the second buckle 410 attached to the first product 400.

[0061] When using the inner skin 220 of the shopping bag 200 with straps as a shopping bag, the first buckle 250 and the second buckle 410 are separated, and the outer skin 210 is slid using the shape maintaining ring 260 to pull out the inner skin 220.

[0062] Thereafter, when the strap combined shopping bag 200 that has been used as a shopping bag is reused as a handy strap for the first product 400, the above-mentioned steps may be carried out in reverse order.

[0063] The process in which the strap-combined shopping bag 200 of the second embodiment of the present invention, configured as described above, is transformed from the handy strap of the first product 400 into a shopping bag is shown in Figures 10(a), (b), (c), and (d).

[0070] The inner skin 320 may be contained within the outer skin 310, and when the inner skin 320 is unfolded, it may be in the form of a shopping bag with one side open.

[0071] In addition, the inner skin 320 may be a folding type that can be alternately folded to a certain width from an open entrance when accommodated in the outer skin 310, and in the alternately folded state, a plurality of through holes 321 may be formed at regular intervals near both side edges.

[0072] The inner layer 320 may be made of a material such as a thin cloth or a non-woven fabric, but is not limited thereto.

[0073] The strap-combined shopping bag 300 can serve as a shoulder strap for the second product 500 when the inner layer 320 is housed in the outer layer 310 described above, and can become a shopping bag in which items can be placed when the outer layer 310 is slid and the inner layer 320 is pulled out and unfolded.

[0074] The outer layer 310 and the inner layer 320 may be separate. That is, when the shopping bag with strap 300 is used as a shopping bag, the outer layer 310 can be completely peeled off from the inner layer 320, and then the outer layer 310 can be stored separately inside the inner layer 320 that has become a shopping bag.

[0075] The shopping bag with strap 300 according to the third embodiment of the present invention may further include a handle 330, a length-adjustable belt 340, and a first buckle 350.

[0076] The handle 330 may be formed by cutting a portion of the inner skin 320 on one side and the other side of the open entrance.

[0077] The length adjustment belts 340 may be provided in pairs on both sides of the inner skin 320 .

[0078] A pair of length-adjustable belts 340 may be alternately passed through each of a plurality of through-holes 321 formed on both sides of the inner skin 320 .

[0079] The pair of length-adjustable belts 340 can be adjusted in length when the strap-combined shopping bag 300 is used as a shoulder strap, and can serve to hold both sides of the shopping bag when the strap-combined shopping bag 300 is used as a shopping bag.

[0080] In addition, when the strap-combined shopping bag 300 is used as a shopping bag and then used again as a shoulder strap, pulling each of the pair of length-adjustable belts 340 outward causes the folding-type inner leather 320 to fold.

[0081] The first buckles 350 may be attached to each of the pair of length adjustable belts 340 in pairs.

[0082] When the inner skin 320 is used as a hand strap for the second product 500, the pair of first buckles 350 can respectively fasten a pair of length-adjustable belts 340 whose lengths are adjusted while the inner skin 320 is housed in the outer skin 310, and can each be coupled to the second buckles 510 attached to the second product 500.
