[0002] As a commonly used packaging material, plastic bottles are widely used in the packaging of food, medicine, etc. They are not easy to break, low cost, high transparency, and food-grade raw materials. Plastic bottles generally include a bottle body and a bottle cap, and the bottle body and the bottle cap are mostly connected by threads. In order to make the packaging more beautiful and personalized, and to attract more customers' attention, we will design the bottle body and the bottle cap of the plastic bottle into a square shape. For this kind of plastic bottle, if the bottle cap and the bottle body are still connected by threads, it is difficult to ensure that the bottle cap and the bottle body are in an aligned state when they are tightened, thereby destroying its aesthetics. Therefore, for this kind of square-capped plastic bottle, we must optimize the design of the combination structure of the bottle cap and the bottle body to overcome the above defects. Utility Model Content
[0003] The utility model aims to solve the above problems in the prior art and to provide a square plastic bottle, so that when the bottle body and the bottle cap are tightly closed, the two are just in an aligned state to ensure the aesthetics.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a square plastic bottle, characterized in that the plastic bottle comprises a square bottle body and a bottle cap, the top of the bottle body has a circular docking port, and a plurality of screw-on convex ribs are evenly distributed on the outer circumferential surface of the docking port; a screw-on ring is fixed on the top of the bottle cap, and convex blocks corresponding to the screw-on convex ribs are evenly distributed on the inner wall of the screw-on ring, and spring pieces are clamped between the convex blocks in the screw-on ring; each of the screw-on convex ribs comprises a clamping strip, a barb and a locking strip, and the clamping strip is located between the barb and the locking strip.
[0005] Preferably, the spring piece comprises a trumpet-shaped spring piece body with an opening facing downward, a pressing ring is horizontally extended outward from the lower end of the spring piece body, and a retaining ring is fixed on the periphery of the pressing ring; a plurality of engaging ribs are provided on the inner wall of the retaining ring, and a sealing aluminum foil is engaged and installed between each engaging rib.
[0006] Preferably, a plurality of sealing convex rings are provided on the lower surface of the pressing ring.
[0007] Preferably, the top of the spring body is concave to form a limiting groove, and a limiting ring matched with the limiting groove is provided on the top of the bottle cap.
[0008] The utility model has the advantages:
[0009] 1. In this plastic bottle, we only need to design the position of the barb and the locking strip to ensure that the bottle cap always remains aligned with the bottle body when the cap is closed, thereby ensuring the aesthetics of the bottle after the cap is closed.
[0010] 2. The opening of the plastic bottle requires certain skills, so that the plastic bottle has a certain child-proof opening function, so that it can be used for the packaging of medicines.
[0011] 3. In this plastic bottle, the cooperation between the sealing aluminum foil, the spring sheet and the sealing convex ring makes it have good sealing performance.

DETAILED DESCRIPTION
[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0018] like Figure 1 , Figure 2 and Figure 4 As shown, a square plastic bottle comprises a square bottle body 1 and a bottle cap 2. The top of the bottle body 1 has a circular docking port 11, and a plurality of screw-on convex ribs 12 are evenly distributed on the outer circumference of the docking port 11. A screw-on ring 21 is fixed on the top of the bottle cap 2, and convex blocks 22 corresponding to the screw-on convex ribs 12 are evenly distributed on the inner wall of the screw-on ring 21. Spring pieces 3 are also engaged between the convex blocks 22 in the screw-on ring 21. Each screw-on convex rib 12 comprises a snap-on strip 121, a barb 122 and a locking strip 123, and the snap-on strip 121 is located between the barb 122 and the locking strip 123.
[0019] When closing the cap of the plastic bottle, we only need to align each protrusion 22 with the gap between the screw-on ribs 12, and then buckle the screw-on ring 21 of the bottle cap 2 on the docking port 11; a spring piece 3 is provided inside the screw-on ring 21, which is located above each protrusion 22. Under the action of its resilience, the bottle cap 2 is always pushed up, so we need to press down the bottle cap 2 and rotate it clockwise, each protrusion 22 will pass over the corresponding barb 122, and under the action of the resilience, under the common lower position of the barb 122 and the locking strip 123, each protrusion 22 will always be close to the locking strip 121, and then the cap is closed. In this cap closing method, we only need to design the positions of the barb 122 and the locking strip 123, so as to ensure that the bottle cap 2 always keeps aligned with the bottle body 1 when closing the cap, thereby ensuring the aesthetics of the bottle after closing the cap, and the presence of the spring piece 3 can keep the bottle cap 2 in a tight state on the bottle body 1, thereby effectively preventing it from falling.
[0020] When opening the cap, we need to press down the bottle cap 2 again to make each protrusion 22 move down to the bottom of the corresponding barb 122, and then rotate the bottle cap 2 counterclockwise to make each protrusion 22 pass over the corresponding barb 122 to complete the opening. The opening of the plastic bottle requires certain skills, so that the plastic bottle has a certain child-proof opening function, so that it can be used for packaging medicines.
[0021] like Figure 1 and Figure 3 The spring piece 3 includes a trumpet-shaped spring piece body 31 with an opening downward, a pressing ring 32 extending horizontally outward from the lower end of the spring piece body 31, and a retaining ring 33 fixed to the periphery of the pressing ring 32; a plurality of engaging convex ribs 34 are arranged on the inner wall of the retaining ring 33, and a sealing aluminum foil 4 is mounted between each engaging convex rib 34. In the present plastic bottle, the spring piece body 31 is made of a plastic sheet, and its trumpet-shaped spring piece body 31 with an opening downward can be deformed to provide a rebound force; the retaining ring 33 cooperates with the engaging convex ribs 34 on its inner wall to limit the sealing aluminum foil 4 in the spring piece 3 at all times; and under the action of the rebound force of the spring piece 3, the pressing ring 32 can press the sealing aluminum foil 4, so that it is always close to the top of the docking port 11, thereby achieving the sealing of the present plastic bottle, thereby extending the shelf life of the packaged items therein.
[0022] And different from the traditional hot-melt bonding aluminum foil sealing method, after the plastic bottle is opened, the sealing aluminum foil 4 can still seal its internal environment when the lid is closed again, while the hot-melt bonding aluminum foil is difficult to continue to perform the sealing function after opening.
[0023] like Figure 3 As shown, a plurality of sealing protrusions 35 are provided on the lower surface of the pressing ring 32. The sealing protrusions 35 on the lower surface of the pressing ring 32 can further enhance the sealing performance of the plastic bottle.
[0024] like Figure 1 and Figure 2As shown, the top of the spring body 31 is concave to form a limiting groove 36, and a limiting ring 23 matching the limiting groove is provided at the top of the bottle cap 2. The cooperation between the limiting groove and the limiting ring 23 allows the downward pressure of the bottle cap 2 to always act on the center of the spring 3, so that the pressing ring on the spring 3 is evenly pressed on the top of the docking port 11, further ensuring its sealing performance.
[0025] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
