Description

Technical Field

[0001] The utility model relates to the technical field of paper bags, in particular to a waterproof foldable paper bag. Background Art

[0002] Paper is a recyclable resource. The raw material for papermaking is mainly plant fiber. In addition to the three main components of cellulose, hemicellulose and lignin, the raw material also contains other components with smaller contents, such as resin and ash. Compared with plastic bags, the raw material of paper bags is trees, which is a renewable resource. At the same time, it is also degradable, recyclable and easy to fold and store, so it is widely used.

[0003] In the prior art, a Chinese patent with announcement number CN220115166U discloses a novel waterproof foldable paper bag, which adopts the scheme of "a main body module including an outer bag body, an extension part symmetrically fixed on the top end of the outer bag body, a hand rope installed on the extension part, a waterproof layer fixed on the inner wall of the outer bag body, an inner bag body fixed on the inner wall of the waterproof layer and with the top end extending upward from the outer bag body, a sealing cover embedded in the top end of the inner bag body, an extrusion plate installed on the inner top wall of the sealing cover, a placement box fixed on the inner bottom wall of the extrusion plate, and activated carbon particles filled in the inner cavity of the placement box; the outer bag body is used to install the inner bag body and play a preliminary protective role for the inner bag body; a waterproof film is provided on the outer side surface of the outer bag body to improve the waterproof performance of the outer bag body and prevent the outer bag body from being damaged by water; a fold is provided on the side of the outer bag body, and the user can fold the outer bag body together with the inner bag body along the fold, thereby improving the portability of the paper bag". The waterproof foldable paper bag has the advantages of good waterproof performance and strong practicality.

[0004] However, the above scheme still has some shortcomings. For example, the above scheme realizes waterproofing by arranging a sealing cover and a placement box in the bag body. The design of the sealing cover and the placement box greatly increases the difficulty and cost of producing the paper bag, and has poor practicality. The design of the sealing cover increases the hardness of the paper bag, affecting its carrying and packaging effects. At the same time, the above scheme lacks a structure to reinforce the overall strength of the paper bag, which causes the paper bag to easily break after long-term use or when it is exposed to water and moisture, causing the items in the paper bag to fall directly, and has poor practicality. In view of this, the utility model proposes a waterproof foldable paper bag. Utility Model Content

[0025] 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 in 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.

[0026] According to the attached Figure 1-5As shown, an embodiment of the utility model provides a waterproof foldable paper bag, including a bag body 1, both side surfaces of the bag body 1 are provided with thread holes, a hand rope 2 is arranged inside the thread hole, an adjustment mechanism is arranged on the surface of one end of the hand rope 2 located inside the bag body 1, and a water retaining mechanism is arranged inside the bag body 1.

[0027] The water retaining mechanism includes two water retaining plates 3 fixedly installed symmetrically on the inner walls on both sides of the bag body 1. The front and rear ends of the two water retaining plates 3 are provided with elastic strips 4 connected to the front and rear walls of the bag body 1. The opposite surfaces of the two water retaining plates 3 are fixedly connected with magnetic strips 5, and the two magnetic strips 5 are magnetically attracted to each other. Drainage holes 6 are opened on the inner walls on both sides of the bag body 1.

[0028] There are several drainage holes 6, and each group of five drainage holes 6 is divided into two groups. The two groups of drainage holes 6 are equidistantly arranged on both sides of the bag body 1, and the positions of the two groups of drainage holes 6 correspond to the two water retaining plates 3 respectively. Through the arrangement of the magnetic strip 5, the water retaining plate 3 and the drainage holes 6, the bag body 1 can be sealed and water-retaining, and rainwater can be discharged through the drainage holes 6.

[0029] The surface of the bag body 1 is coated with a waterproof layer, and a reinforcing mesh layer 7 is embedded inside the shell of the bag body 1. The reinforcing mesh layer 7 is made of nylon mesh material. Through the arrangement of the waterproof layer and the reinforcing mesh layer 7, the paper bag can have a waterproof effect, and under the action of the reinforcing mesh layer 7, the items in the bag body 1 can be protected when the paper bag is damaged, thereby preventing the items from falling directly.

[0030] The adjustment mechanism includes a limit box 8 arranged on the surface of one end of the hand rope 2. The surface of the limit box 8 is provided with a through-line opening. The limit box 8 is slidably connected to the surface of the hand rope 2 through the through-line opening.

[0031] A spring 9 is fixedly installed on the inner wall of the limit box 8, and a snap ring 10 is fixedly connected to the end of the spring 9 away from the inner wall of the limit box 8. A sliding opening that penetrates into the interior of the limit box 8 is opened on one side surface of the limit box 8, and an operating rod 11 that is slidably connected to the inside of the sliding opening is fixedly connected to the side surface of the snap ring 10 away from the spring 9. Through the setting of the limit box 8 with the spring 9 and the snap ring 10, the snap ring 10 can be misaligned with the wire opening on the surface of the limit box 8 to clamp the hand rope 2, so that the limit box 8 is fixed on the surface of the hand rope 2.

[0032] The upper and lower surfaces of the retaining ring 10 are both provided with guide sliders 12, and the inner top wall and the inner bottom wall of the limit box 8 are both provided with limit sliding grooves for the guide slider 12 to slide. Under the guiding and sliding action of the guide slider 12, the spring 9 can push the retaining ring 10 to move smoothly in the limit box 8.

[0033] Working principle: after placing the items in the paper bag, the two water baffles 3 are closed by the magnetic strips 5, which play a sealing and water-blocking effect in the bag body 1. The water baffles 3 drain the rainwater and discharge it through the drainage holes 6 to prevent rainwater from falling into the bag body 1. At the same time, under the action of the reinforced mesh layer 7, the items in the bag body 1 can be protected when the paper bag is damaged to prevent the items from falling directly. When it is necessary to adjust the pulling length of the paper bag hand rope 2, the operating rod 11 is pressed to drive the clamping ring 10 to move in the limit box 8 until the clamping ring 10 is aligned with the through-line opening on the surface of the limit box 8. In the absence of the limit of the clamping ring 10, the limit box 8 and the surface of the hand rope 2 can be pushed to move, and the hand rope 2 can be retracted and released, thereby achieving the purpose of adjusting the pulling length of the hand rope 2.
