Description

Technical Field

[0001] This utility model relates to the field of plastic bottle technology, specifically to a polyethylene plastic bottle with a pusher structure. Background Technology

[0002] Plastic bottles are primarily made from materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded into plastic containers through blow molding, extrusion blow molding, or injection molding. They are mainly used for single-use plastic packaging containers for liquids or solids such as beverages, food, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles are characterized by their resistance to breakage, low cost, high transparency, and use of food-grade raw materials. However, existing polyethylene plastic bottles still have certain drawbacks in use, such as…

[0003] When polyethylene plastic bottles are filled with viscous solutions, the solutions flow slowly and a lot of the solution adheres to the inner wall of the bottle, making it difficult to pour out. Furthermore, most existing polyethylene plastic bottles do not have a feeding mechanism, and the size of the discharge port is fixed after the cap is opened, making it impossible to adjust the discharge speed as needed. Utility Model Content

[0004] The purpose of this invention is to provide a polyethylene plastic bottle with a pusher structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyethylene plastic bottle with a pushing structure, comprising: a bottle body, a bottle cap, a pushing mechanism, and a flow limiting mechanism;

[0006] A bottle cap is threadedly connected to the top of the bottle body, and a pushing mechanism is provided at the bottom of the bottle body. A flow limiting mechanism is provided inside the bottle body near the bottle cap.

[0007] The feeding mechanism includes a circular plate, a sealed bearing, a threaded rod, a piston, and a sliding rod. The bottom of the bottle body abuts against the circular plate, and a sealed bearing is connected through the lower part of the inner wall of the bottle body.

[0008] Preferably, the sealed bearing has a threaded rod connected inside, and the threaded rod is connected to the upper surface of the circular plate.

[0009] Preferably, a piston is threadedly connected to the outer side of the threaded rod, and the piston abuts against the inner wall of the bottle.

[0010] Preferably, a sliding rod is slidably inserted through the piston, and the sliding rod is connected to the inner wall of the bottle.

[0011] Preferably, the flow limiting mechanism includes: an annular groove, a large bevel gear, a small bevel gear, a handle, a baffle, a shaped opening, and a through-hole. An annular groove is provided on the inner wall of the bottle body near the bottle cap, and a large bevel gear is rotatably connected to the inner wall of the annular groove.

[0012] Preferably, a small bevel gear is meshed with one side of the large bevel gear, and a handle is connected to one side of the small bevel gear. The handle rotates through one side of the inner wall of the annular groove.

[0013] Preferably, a baffle is rotatably connected to the bottom of the large bevel gear, and the baffle is connected to the inner wall of the bottle.

[0014] Preferably, the baffle has an irregularly shaped opening, and the large bevel gear has a through opening.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The polyethylene plastic bottle with a pushing structure uses a rotating circular plate to drive a threaded rod to rotate, pushing a piston to scrape the residual liquid on the inner wall of the bottle upwards, thus allowing the polyethylene plastic bottle to push the material; the polyethylene plastic bottle with a pushing structure also uses a rotating handle to drive a large bevel gear to rotate above a baffle, adjusting the gap between the opening and the irregularly shaped opening, thereby controlling the discharge speed of the polyethylene plastic bottle. The specific details are as follows:

[0016] 1. By rotating the circular plate, the threaded rod rotates within the sealed bearing, which in turn drives the piston to scrape the residual liquid on the inner wall of the bottle upwards, reducing the amount of solution remaining, thereby allowing the polyethylene plastic bottle to be pushed.

[0017] 2. By rotating the handle, the small bevel gear drives the large bevel gear, which offsets the through-hole from the irregular-shaped opening, thus controlling the discharge speed and allowing the polyethylene plastic bottle to control the discharge speed. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This utility model provides a technical solution: a polyethylene plastic bottle with a pushing structure, comprising: a bottle body 1, a bottle cap 2, a pushing mechanism 3, and a flow limiting mechanism 4; the bottle cap 2 is threadedly connected to the upper part of the bottle body 1, and the pushing mechanism 3 is provided at the lower part of the bottle body 1, and the flow limiting mechanism 4 is provided inside the bottle body 1 near the bottle cap 2; the pushing mechanism 3 comprises: a circular plate 301, a sealing bearing 302, a threaded rod 303, a piston 304, and a sliding rod 305; the bottom of the bottle body 1 abuts against the circular plate 301, and the sealing bearing 302 is penetratingly connected to the lower part of the inner wall of the bottle body 1; the threaded rod 303 is connected to the sealing bearing 302, the threaded rod 303 is connected to the upper surface of the circular plate 301, the piston 304 is threadedly connected to the outer side of the threaded rod 303, the piston 304 abuts against the inner wall of the bottle body 1, and the sliding rod 305 slides through the piston 304, the sliding rod 305 is connected to the inner wall of the bottle body 1.

[0025] In practice, a sealed bearing 302 is used to seal the gap between the threaded rod 303 and the bottle body 1. The rotating disc 301 drives the threaded rod 303 to rotate, and the threaded rod 303 drives the piston 304 to move along the slide rod 305. The piston 304 scrapes the residual liquid on the inner wall of the bottle body 1 upward to reduce the residue of the solution, so that the polyethylene plastic bottle can be pushed.

[0026] See Figures 2-4It is known that the flow limiting mechanism 4 includes: an annular groove 401, a large bevel gear 402, a small bevel gear 403, a handle 404, a baffle 405, a shaped opening 406, and a through-hole 407. An annular groove 401 is provided on the inner wall of the bottle body 1 near the bottle cap 2. A large bevel gear 402 is rotatably connected to the inner wall of the annular groove 401. A small bevel gear 403 is meshed with one side of the large bevel gear 402. A handle 404 is connected to one side of the small bevel gear 403. The handle 404 rotates through one side of the inner wall of the annular groove 401. A baffle 405 is rotatably connected to the bottom of the large bevel gear 402. The baffle 405 is connected to the inner wall of the bottle body 1. A shaped opening 406 is provided in the baffle 405. A through-hole 407 is provided in the large bevel gear 402.

[0027] In practice, rotating the handle 404 drives the small bevel gear 403 to rotate, and the small bevel gear 403 drives the large bevel gear 402 to rotate above the baffle 405, thus misaligning the through-hole 407 with the irregular opening 406. Adjusting the gap between the through-hole 407 and the irregular opening 406 allows the polyethylene plastic bottle to control the discharge speed.

[0028] In summary: When using this polyethylene plastic bottle with a pusher structure, firstly, when it is necessary to pour out the solution inside the polyethylene plastic bottle, rotate to remove the bottle cap 2. Then, adjust the gap between the opening 407 and the irregular opening 406 by rotating the handle 404 according to the required discharge speed. Tilt the bottle body 1 to pour. If the solution is viscous or there is a lot of residual solution that has not been poured out, rotate the circular plate 301 to drive the piston 304 to push the solution towards the bottle opening of the bottle body 1 for discharge. The contents not described in detail in this description are prior art known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
