Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to a puncture-resistant durian packaging bag. Background Technology

[0002] Durian is a tropical fruit with a high and balanced nutritional density. Its flesh contains a large amount of starch, sugar, fat, carbohydrates, and protein, as well as various vitamins and minerals such as calcium, iron, magnesium, and zinc. When selling durians, they need to be packaged in bags for easy carrying by buyers. When packaging a whole durian, because durians have many sharp thorns and are quite hard, the bag and durian will shake during the buyer's movement. This causes the bottom of the bag to bear more and more force, which is more concentrated and easily leads to breakage and the durian falling out. Utility Model Content

[0019] This embodiment includes a packaging bag body 1, with an open top. By placing the durian inside the packaging bag body 1, the durian can be packaged and moved using the packaging bag body 1. The packaging bag body 1 includes a food contact layer 11, a leak-proof isolation layer 12, a cushioning layer 13, a protective layer 14, and a wear-resistant layer 15. The food contact layer 11 can be made of PP film and comes into direct contact with the food. The leak-proof isolation layer 12 is an aluminum foil composite film. The cushioning layer 13 is closed-cell foam. The protective layer 14 is a non-woven fabric. The wear-resistant layer 15 can be made of Oxford cloth. Layer 14 and abrasion-resistant layer 15 give the packaging bag body 1 a puncture-resistant effect. The food contact layer 11, impermeable isolation layer 12, buffer layer 13, protective layer 14, and abrasion-resistant layer 15 are sequentially composited from the inside out, with the food contact layer 11 located on the innermost side and the abrasion-resistant layer 15 on the outermost side. The impermeable isolation layer 12, buffer layer 13, and protective layer 14 are located sequentially between the food contact layer 11 and the abrasion-resistant layer 15. Both sides of the packaging bag body 1 are equipped with handles 2, positioned opposite each other, facilitating the lifting of the packaging bag body 1. The interior of the packaging bag body 1 contains several support straps 3 and 4. The supporting strap 2 4 has the same structure, and supporting strap 1 3 and supporting strap 2 4 are deformable thin plastic strips. Several supporting straps 1 3 and several supporting straps 2 4 are staggered, and supporting straps 1 3 and supporting strap 2 4 do not contact each other. The inclination angles of supporting straps 1 3 and supporting strap 2 4 are opposite. The bottom of the packaging bag body 1 is provided with an arc plate 5, which is fixedly connected to the packaging bag body 1. The arc plate 5 can support the bottom of the packaging bag body 1, which helps to improve the stress strength of the bottom of the packaging bag body 1. At the same time, it can further prevent the bottom of the packaging bag body 1 from being pierced by durian. Connecting strips 1 are provided on both sides of the packaging bag body 1. The positions of connecting strip 31 and connecting strip 41 are symmetrical, and the dimensions of connecting strip 31 and connecting strip 41 are the same. The two ends of the supporting strip 3 are fixedly connected to the arc plate 5 and connecting strip 31 respectively, and the two ends of the supporting strip 4 are fixedly connected to the arc plate 5 and connecting strip 41 respectively. When the durian enters the interior of the packaging bag body 1, the supporting strip 3 and supporting strip 4 will deform under the pressure of the durian. The durian can be supported by several supporting strips 3 and several supporting strips 4, reducing the pressure exerted by the durian on the packaging bag body 1, thereby helping to reduce the situation where the packaging bag body 1 is punctured by the durian.

[0020] The packaging bag body 1 has several through slots 16 on one side. One end of the support belt 4 passes through the through slot 16 and is fixedly connected to the arc plate 5. The packaging bag body 1 also has several through slots 17 on one side. One end of the support belt 3 passes through the through slot 17 and is fixedly connected to the arc plate 5. The through slots 16 and 4 are matched in size, and the through slots 17 and 3 are matched in size.

[0021] The second channel 17 has the same size as the first channel 16, and several channels 16 and several channels 2 17 are staggered. Several channels 16 and several channels 2 17 are located on both sides of the packaging bag body 1. Several channels 16 are arranged at equal intervals, and several channels 2 17 are arranged at equal intervals. Supporting belt 3 is fixed to the inside of channel 2 17, and supporting belt 4 is fixed to the inside of channel 16.

[0022] The packaging bag body 1 has several through holes 18 on one side. The end of the support belt 3 away from the arc plate 5 passes through the through hole 18 and is fixedly connected to the connecting strip 31. The packaging bag body 1 has several through holes 29 on one side. The end of the support belt 2 away from the arc plate 5 passes through the through hole 29 and is fixedly connected to the connecting strip 241. The through hole 18 matches the size of the support belt 3, and the through hole 29 matches the size of the support belt 24.

[0023] Through hole 18 and through hole 2 19 are the same size, and several through holes 18 and several through holes 2 19 are staggered with each other. Several through holes 18 and several through holes 2 19 are located on both sides of the packaging bag body 1. Several through holes 18 are arranged at equal intervals, and several through holes 2 19 are arranged at equal intervals. Supporting strap 1 3 is fixed inside through hole 18, and supporting strap 2 4 is fixed inside through hole 2 19.

[0024] Through groove 16 and through hole 18 are located on the same side, and through groove 2 17 and through hole 2 19 are located on the same side; several support belts 1 3 and several support belts 2 4 are in an intersecting state. When the durian is located on several support belts 1 3 and support belts 2 4, the durian can be supported by several support belts 1 3 and support belts 2 4.

[0025] The bottom of the curved plate 5 is provided with two support legs 51, which are symmetrical to each other. The support legs 51 are fixedly connected to the curved plate 5. The two support legs 51 allow the curved plate 5 to be placed on a table or other position, which helps to improve the stability of the packaging bag body 1, the curved plate 5 and the durian, and prevents the durian from rolling out of the packaging bag body 1.

[0026] The working principle and usage process of this utility model are as follows: By placing the durian inside the packaging bag body 1, the durian can be moved by lifting the packaging bag body 1. The food contact layer 11, the seepage-proof isolation layer 12, the buffer layer 13, the protective layer 14, and the wear-resistant layer 15 make the packaging bag body 1 puncture-proof. When the durian enters the packaging bag body 1, the first support belt 3 and the second support belt 4 will deform under the pressure of the durian. The durian can be supported by several first support belts 3 and several second support belts 4, reducing the pressure exerted by the durian on the packaging bag body 1. The arc plate 5 can support the bottom of the packaging bag body 1, which helps to improve the stress strength of the bottom of the packaging bag body 1 and further prevents the bottom of the packaging bag body 1 from being punctured by the durian.
