Description

Technical Field

[0001] The utility model belongs to the technical field of storage bags, and in particular relates to a high-load-bearing degradable plastic shopping bag. Background Art

[0002] A shopping bag is a bag used for shopping. The main shopping bags available on the market are: plastic shopping bags, non-woven shopping bags, paper shopping bags, and cotton and linen shopping bags, etc. Today's society pursues a green and environmentally friendly lifestyle. Due to the increase in population, the demand for shopping bags is also increasing. In view of the fact that it will cause a lot of pollution, degradable and environmentally friendly shopping bags have been used.

[0003] The first Chinese patent with publication number CN212014734U discloses a high-load-bearing plastic shopping bag, which consists of a shopping bag body, handles and buckles. Two handles corresponding to each other are sewn and connected to the upper middle part of the outer side of the shopping bag body, and the buckles are fixedly connected to the inner side of the top of the shopping bag body in groups of two. When in use, after storing the goods in the shopping bag, the bag opening of the shopping bag is sealed with the buckle and the goods can be taken away with the handles.

[0004] The second Chinese patent with publication number CN216059482U discloses an environmentally friendly shopping bag, which is composed of an environmentally friendly shopping bag, a handle rope, a protective pad and a reinforcement belt. Two corresponding handle ropes are also fixedly connected to the upper end of the shopping bag body, the protective pad is fixedly connected to the upper middle part of the handle rope, and the reinforcement belt is fixedly connected to the connection between the handle rope and the environmentally friendly shopping bag. When in use, the contact area between the handle rope and the shopping bag body is enhanced by adding the reinforcement belt, and the handle rope will not fall off. The protective pad is added to avoid strangulation when lifting heavy objects.

[0005] However, in the technical solutions of the above-mentioned patents, the hand rope is fixed above the shopping bag, and the hand rope is fixed on the surface of the shopping bag in a point-to-surface connection manner. During use, the shopping bag is lifted by the hand rope, and the force points are concentrated on the connection between the hand rope and the shopping bag. Therefore, the hand rope is very easy to break and fall off, and the load-bearing effect is poor. In the second patent, although the contact area between the hand rope and the shopping bag is strengthened by adding a reinforcement belt and the connection strength is improved to a certain extent, when lifting heavy objects, the hand rope is still easy to fall off and cause local damage to the bag body, so the load-bearing effect is also poor. Utility Model Content

[0006] In order to solve the technical problem in the prior art that the connection between the hand rope and the shopping bag is prone to breakage and falling off due to concentrated force, the utility model provides a high-load-bearing biodegradable plastic shopping bag.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A high-load-bearing degradable plastic shopping bag, comprising a bag body with upper and lower hollows; a bottom plate is sewn and connected to the bottom of the bag body; symmetrically arranged hand ropes are provided through the bottom plate, and the hand ropes are all located on the long side of the bottom plate; a limiting component is fixedly connected to the top of the bag body;

[0009] The limiting assembly comprises a limiting block fixedly connected to the inner side of the top of the bag body in a one-to-one correspondence with the hand rope, and the limiting block is sewn to the bag body, and the hand rope is penetrated and arranged inside the limiting block.

[0010] Furthermore, the limiting assembly includes wire-passing holes which are opened at the top of the bag body in a one-to-one correspondence with the hand rope, and the hand rope passes through the wire-passing holes from the inside to the outside and is arranged on the outside of the bag body.

[0011] Furthermore, a groove is provided on the lower surface of the bottom plate at a position corresponding to the hand rope; a matching hard plate is sewn and connected in the groove.

[0012] Furthermore, the hard plate is provided with holes at positions corresponding to the hand ropes, and the turning points of the holes are smooth curved surfaces.

[0013] Furthermore, the hand rope is provided with symmetrically arranged sleeves at positions corresponding to the upper part of the bag body, and the sleeves are slidably connected to the hand rope.

[0014] Furthermore, a limiting rope is arranged through the top side of the bag body, and the limiting rope is arranged to pass back and forth on both sides of the bag body.

[0015] Beneficial effects of the utility model:

[0016] The utility model adopts the arrangement of a bag body, a hand rope and a bottom plate, and selects and sews soft plastic, cloth or hard acrylic plate with high connection strength at the bottom of the bag body, so as to increase the strength of the bottom of the bag body and improve the load-bearing strength of the bag body. In addition, the hand rope is connected to the bottom plate with high strength, and the original point-to-surface connection mode between the hand rope and the bag body is changed to a line-to-surface connection mode. The bag body is lifted from the bottom of the bag body, and the stress points between the original hand rope and the bag body are evenly distributed, so that the load-bearing performance of the shopping bag is greatly improved, and the hand rope will not fall off the bag body when the load-bearing is high.

[0017] The utility model provides a limiting rope, and the limiting rope that runs back and forth through the inside and outside of the bag body can limit the position of the bag body when it is stretched out in all directions. Since the bottom of the bag body is fixed by the bottom plate, the upper and lower ends of the bag body will not be easily torn, thereby improving the weighing strength of the bag body. At the same time, when the bag body is sealed, the middle part of the limiting rope can be directly drawn out, so that the sealing of the bag body is directly closed, and the bag mouth of the bag body can be perfectly closed in combination with the hand rope.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] See also Figure 1 - Figure 2 As shown, a high-load-bearing biodegradable plastic shopping bag comprises a bag body 1 which is hollow at the top and the bottom; a bottom plate 2 is sewn and connected to the bottom of the bag body 1; symmetrically arranged hand ropes 3 are provided through the bottom plate 2, and the hand ropes 3 are all located on the long side of the bottom plate 2; a limiting component is fixedly connected to the top of the bag body 1;

[0029] The limiting assembly includes a limiting block 4 fixedly connected to the inner side of the top of the bag body 1 and corresponding to the hand rope 3 in a one-to-one manner, and the limiting block 4 is sewn to the bag body 1, and the hand rope 3 is arranged inside the limiting block 4.

[0030] In order to solve the technical problem in the prior art that the connection between the hand rope 3 and the shopping bag is prone to breakage due to concentrated force, in actual use, the purchased goods are stored in the bag body 1, the bag mouth is sealed, and finally the hand rope 3 is used to carry the bag away.

[0031] Among them, soft plastic, cloth or hard acrylic plate with high connection strength is selected and sewn at the bottom of the bag body 1 to increase the strength of the bottom of the bag body 1 and improve the load-bearing strength of the bag body 1. In addition, the hand rope 3 is connected to the bottom plate 2 with high strength, and the original point-surface connection mode between the hand rope 3 and the bag body 1 is changed to a line-surface connection mode, and the bag body 1 is lifted from the bottom of the bag body 1, and the stress points between the original hand rope 3 and the bag body 1 are evenly distributed, which greatly improves the load-bearing performance of the shopping bag, and the hand rope 3 will not fall off the bag body 1 when the load is high;

[0032] The position of the hand rope 3 is fixed by the cooperation between the limit block 4 and the hand rope 3 , and when the bag opening of the bag body 1 is closed, the hand rope 3 can be used to tie a knot to complete the sealing of the bag body 1 .

[0033] Embodiment 2:

[0034] Please refer again Figure 3 As shown, in another embodiment of the utility model, the limiting assembly includes wire holes 10 opened at the top of the bag body 1 corresponding to the hand rope 3, and the hand rope 3 passes through the wire holes 10 from the inside to the outside and is arranged on the outside of the bag body 1.

[0035] Since the hand rope 3 is tied from the inside of the bag body 1, it is easy to make the sealing part on the bag body 1 difficult to close, causing the bag mouth to turn outward, and the setting of the limit block 4 brings trouble to the manufacturer. In specific use, a wire hole 10 is opened at the top of the bag body 1, and the upper end of the hand rope 3 is set on the outside of the bag body 1. When tying the knot, the bag mouth can be completely closed without turning outward, and the manufacturer only needs to punch holes during production, which is more convenient. However, compared with the use of the limit block 4 that causes holes in the bag body 1, it can be selected by the manufacturer when using it.

[0036] Please refer again Figure 2 , Figure 4 as well as Figure 5 As shown, in one embodiment of the present utility model, a groove 5 is provided on the lower surface of the bottom plate 2 at a position corresponding to the hand rope 3; a matching hard plate 6 is sewn and connected inside the groove 5.

[0037] When a soft bottom plate 2 is selected, the bottom of the bag body 1 may shrink when the hand rope 3 is manually lifted, making the shopping bag inconvenient to use. In actual use, the groove 5 and the hard plate 6 can be arranged to prevent the bottom of the bag body 1 from being deformed when the bag body 1 is lifted, and at the same time, the wear of the hand rope 3 on the bottom plate 2 can be reduced, thereby increasing the service life.

[0038] In one embodiment of the present invention, the hard plate 6 is provided with through holes 7 at positions corresponding to the hand rope 3 , and the inflection points of the through holes 7 are smooth curved surfaces.

[0039] By setting the perforation 7 as a smooth curved surface, the wear between the hand rope 3 and the hard plate 6 can be reduced, thereby preventing the hand rope 3 from breaking, thereby increasing the service life.

[0040] Please refer again Figure 1 - Figure 3 As shown, in one embodiment of the present utility model, the hand rope 3 is provided with symmetrically arranged sleeves 8 at positions corresponding to the upper part of the bag body 1, and the sleeves 8 are slidably connected to the hand rope 3.

[0041] In order to prevent the palm from being strangled when the hand rope 3 is manually lifted, the sleeve 8 is slid to the middle of the hand rope 3 during use, and then the bag body 1 is lifted by the cooperation of the sleeve 8 and the hand rope 3 to avoid palm injuries; when the bag body 1 is sealed, the sleeve 8 is slid to both sides to prevent the sleeve 8 from affecting the knotting of the hand rope 3, which is more convenient.

[0042] Please refer again Figure 1 As shown, in one embodiment of the present invention, a limiting rope 9 is provided through the top side of the bag body 1 , and the limiting rope 9 is provided to pass through the inner and outer sides of the bag body 1 back and forth.

[0043] Since the bag body 1 is easily stretched out when storing a lot of items, in order to prevent the bag body 1 from bursting and further improve the load-bearing strength of the bag body 1, during the specific operation, the limit rope 9 that runs through the bag body 1 back and forth can be used to limit the bag body 1 when it is stretched out. Since the bottom of the bag body 1 is fixed by the bottom plate 2, the upper and lower ends of the bag body 1 will not be easily torn, thereby improving the weighing strength of the bag body 1.

[0044] At the same time, when the bag body 1 is sealed, the middle part of the limiting rope 9 can be directly drawn, so that the bag body 1 is directly sealed, and the bag mouth of the bag body 1 can be perfectly sealed in cooperation with the hand rope 3.

[0045] Working principle:

[0046] A soft plastic, cloth or hard acrylic plate with high connection strength is selected and sewn at the bottom of the bag body 1 to increase the strength of the bottom of the bag body 1 and improve the load-bearing strength of the bag body 1. In addition, the hand rope 3 is connected to the bottom plate 2 with high strength, and the original point-to-surface connection mode between the hand rope 3 and the bag body 1 is changed to a line-to-surface connection mode, and the bag body 1 is lifted from the bottom of the bag body 1 to evenly distribute the stress points between the original hand rope 3 and the bag body 1, which greatly improves the load-bearing performance of the shopping bag and will not cause the hand rope 3 to fall off the bag body 1 when the load is high; the position of the hand rope 3 is fixed by the cooperation between the limit block 4 and the hand rope 3, and when the bag mouth of the bag body 1 is closed, the hand rope 3 can be used to tie a knot to complete the sealing of the bag body 1.
