[0018] The present invention is further described below through specific implementation methods.

[0019] like Figure 1 and Figure 2 As shown, the utility model relates to a bag that does not need to be turned over and sewn, comprising a top cover 1, a bag body 2 and a bottom cover 3 arranged in sequence from top to bottom, wherein the bag body 2 comprises a plurality of side panels, and the plurality of side panels are sequentially connected end to end and enclosed in a cylindrical shape, wherein the side edges of at least one group of adjacent two side panels are detachably connected by a first connecting member 4, and the side edges of the remaining groups of adjacent two side panels are fixedly sewn and connected by sutures.

[0020] Preferably, the first connecting member 4 is a first zipper. In other embodiments, the first connecting member 4 may also be a button, a snap button, a Velcro or a strap.

[0021] In addition, the multiple bottom edges of the bag body 2 correspond to the multiple side edges of the bottom cover 3 one by one and are fixedly sewn together by sutures. In addition, in other embodiments, the multiple bottom edges of the bag body 2 and the multiple side edges of the bottom cover 3 can also be detachably connected by a third zipper. Preferably, the bottom cover 3 is a hard bottom cover 3, and the hard bottom cover 3 can be made of materials such as rubber, plastic, and silicone, thereby providing better support for the bottom of the bag, which is beneficial to improving the stability of the bag when placed and preventing it from tipping over.

[0022] In addition, the multiple top edges of the bag body 2 correspond one-to-one to the multiple side edges of the top cover 1, wherein one group of the top edges of the bag body 2 and the side edges of the top cover 1 are fixedly sewn together by sutures, and the top edges of the remaining groups of the bag body 2 and the side edges of the top cover 1 are detachably connected by a second connecting member 5. In other embodiments, the multiple top edges of the bag body 2 and the multiple side edges of the top cover 1 can all be detachably connected by the second connecting member 5. Preferably, the second connecting member 5 is a second zipper. In other embodiments, the second connecting member 5 can also be buttons, snaps, Velcro or straps, etc.

[0023] Correspondingly, the number of the side panels of the bag body 2 is four, namely a front panel 21 , a back panel 22 , a left panel 23 and a right panel 24 .

[0024] Preferably, the first connecting member 4 is arranged between the side edge of the left piece 23 and the side edge of the rear piece 22 or between the side edge of the right piece 24 and the side edge of the rear piece 22, and the second connecting member 5 is arranged between the top edges of the left piece 23, the front piece 21 and the right piece 24 and the three corresponding side edges on the top cover 1.

[0025] In addition, a top cavity open downward is provided in the top cover 1, and a bottom cavity open upward is provided in the bottom cover 3. The outer diameter of the bottom of the bag body 2 is adapted to the inner diameter of the bottom cavity of the bottom cover 3. In this way, when the bag body 2 and the bottom cover 3 are sewn together, the bottom of the bag body 2 can be first extended into the bottom cavity of the bottom cover 3, which further facilitates smooth sewing between the two.

[0026] In addition, two shoulder straps 6 are provided on the rear side of the rear panel 22 , and the upper and lower ends of the two shoulder straps 6 are fixedly sewn to the upper and lower ends of the rear panel 22 by sutures.

[0027] The method for making a bag without turning over and sewing is as follows:

[0028] Sewing the four side panels in sequence, and sewing the binding fabric at the seams between two adjacent side panels, and then sewing the two first chain straps of the first zipper to the side edges of the first and last side panels respectively. Then, closing the four side panels and closing the first zipper to form a tubular bag body 2, with the seams between two adjacent side panels located on the inner side of the bag body 2;

[0029] Insert the bottom of the bag body 2 into the bottom cavity of the bottom cover 3, and insert the corresponding parts of the sewing equipment into the top opening of the bag body 2. Then, sew the four bottom edges of the bag body 2 to the four side edges of the bottom cover 3 one by one, and sew the hemming cloth at the sewing places;

[0030] Sew one of the top edges of the bag body 2 to one of the side edges of the top cover 1, and sew the edging cloth at the sewing point, and then sew the two second chain straps of the second zipper to the other three top edges of the bag body 2 and the three side edges of the top cover 1 respectively. Close the second zipper to achieve the connection between the other three top edges of the bag body 2 and the three side edges of the top cover 1.

[0031] As a result, by providing the first zipper and the second zipper, during the entire sewing process of the bag, especially for some valuable bags made of EVA or leather materials, the entire sewing of the bag can be completed without turning the bag over, and the sewing area can be hidden inside the bag to ensure that no creases or wrinkles are generated on the bag surface during the sewing process, which is conducive to ensuring the overall beautiful appearance of the bag and the quality of the finished product.

[0032] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this.
