[ detailed description ] embodiments

A three-dimensional vacuum compression bag comprises a bottom plate 1, a front plate 2, a left side plate 3, a rear plate 4 and a right side plate 5 which are connected with four side edges of the bottom plate 1, top plates 6 are connected with top sides of the front plate 2, the left side plate 3 and the right side plate 5, two side edges of a rear side section of each top plate 6 are respectively welded with two side edges of an upper side section of the rear plate 4 so as to enable an object containing space to be formed among the bottom plate 1, the front plate 2, the left side plate 3, the rear plate 4, the right side plate 5 and the top plates 6, an air suction valve 7 used for sucking and compressing the object containing space is arranged on the front plate 2 or the rear plate 4, an opening 8 capable of opening the object containing space is formed between the rear plate 4 and the top plates 6, a sealing rib 9 capable of closing the opening 8 is arranged on the opening 8, intersection points A are formed at two side positions of the opening 8 when two side edges of the rear side section of the top plate 6 are welded with two side edges of the upper side section of the rear plate 4, the two sides of the back section of the top sheet 6 are welded with the two sides of the upper section of the back sheet 4, and an intersection B is formed at the intersection of the left side sheet 3 and the right side sheet 5. The utility model discloses an opening 8 is only formed by the both sides butt fusion of back part 4 and top piece 6 mutually, consequently there is not the condition of multilayer butt fusion in the intersection A of its opening 8 position department, simple process when sealing up the butt fusion of bone strip 9, the processing production of being convenient for, and can form another intersection B between left side piece 3 or the right side piece 5 when back part 4 and the butt fusion of top piece 6 convex both sides mutually, thereby disperse the stress of intersection A of opening 8 position department, play the effect of sharing stress, make the bag body can bear higher stress.

For further convenience of processing, the bottom sheet 1, the front sheet 2 and the top sheet 6 are integrally formed. The left side panel 3, the front panel 2 and the right side panel 5 are integrally formed.

In order to better distribute the stress at the intersection point a at the position of the opening 8 to further improve the stress bearing capacity of the bag body, a T-shaped welding structure 11 (shown in fig. 2 and 6) is formed between the back sheet 4 and the top sheet 6 and the left side sheet 3 or the right side sheet 5 at the position of the intersection point B by welding.

In order to facilitate carrying and carrying of the bag body, the left side piece 3, the right side piece 5 or the top piece 6 are provided with a handle structure 10. As shown in fig. 3, the handle structure 10 is provided on the left side panel 3. The handle structure 10 is provided on the top sheet 6 as shown in figure 4.

In order to improve the bearing capacity of the handle structure 10 while facilitating lifting, the handle structure 10 is a drawstring 101 with two ends welded with the left side piece 3, the right side piece 5 or the top piece 6, and the number of the drawstrings 101 is 2.

To prevent stress concentration, a reinforcing connecting sheet 102 (shown in fig. 3 and 4) is welded to the inner side of the left side sheet 3, the right side sheet 5, or the top sheet 6 at the position where the draw tape 101 is welded.

In order to facilitate the folding and storage of the bag body when the bag body does not need to store articles, the bottom sheet 1, the left side sheet 3, the right side sheet 5 and the top sheet 6 are provided with folding lines 100 (as shown in fig. 5 and 6) which can fold the bottom sheet 1, the left side sheet 3, the right side sheet 5 and the top sheet 6 inwards.

The utility model discloses during the use, will be such as clothing, quilt, pillow, fibre, fur, silk fabric etc. need accomodate article through opening 8 put into the thing space of the bag body in, close sealed rib 9 with involution opening 8 after having placed article, then utilize the aspiration pump to bleed through 7 opposition object spaces of bleeder valve and compress to the realization carries out vacuum packaging to the splendid attire article in putting the object space. As shown in fig. 7, since the intersection B effectively disperses the stress at the intersection a, the intersection a and the intersection B can share about f/2 of the stress (as shown in fig. 8, if there is no sharing effect of the intersection B, the intersection at the opening position needs to bear all the stress f), so as to share the stress, so that the bag can bear higher stress, and the service life of the bag is longer.
