Description

Technical Field

[0001] The utility model belongs to the technical field of plastic bottles and relates to a plastic bottle, in particular to a new type of plastic bottle. Background Art

[0002] Plastic bottles are made of polyester, polyethylene, and polypropylene as raw materials, with the corresponding organic solvents added, and then heated at high temperature and passed through a plastic mold by blow molding, extrusion blow molding, or injection molding. Plastic bottles are not easy to break, low cost, high transparency, easy to carry, and easy to recycle, so more and more products choose to be packaged in plastic bottles.

[0003] The existing plastic bottle locking system requires the bottle cap to be rotated several times to complete the locking, which is time-consuming and laborious. Moreover, after tightening, there is a lack of special sealing measures, and there is still a slight gap between the cap and the bottle mouth. When some volatile items are placed, a good sealing effect cannot be achieved. Summary of the invention

[0004] The purpose of the utility model is to provide a new type of plastic bottle which is convenient to lock in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of plastic bottle, comprising a bottle body and a bottle cap, the top of the bottle body having an integrally formed bottle mouth, characterized in that a locking device is provided at the inner end of the bottle cap, the locking device consists of a locking disk and a clamping disk, the locking disk is arranged on the inner side of the clamping disk, four clamping parts are fixedly provided on the locking disk, and the four clamping parts are each provided with a clamping protrusion, and four locking blocks are fixedly provided on the inner wall of the clamping disk, and a locking groove for locking and an unlocking groove for unlocking are respectively provided on the inner wall of the clamping disk and on both sides opposite to the locking block, the diameter of the unlocking groove is larger than the diameter of the locking groove, and pressing strips are provided on the inner walls of the four clamping parts, and a positioning part is provided on the inner wall of one of the clamping parts.

[0006] In the above-mentioned novel plastic bottle, the positioning disk and the bottle cap are integrally arranged, the inner wall of the bottle cap is provided with a rotating shaft, the locking disk is arranged on the rotating shaft, and can rotate on the rotating shaft.

[0007] In the above-mentioned novel plastic bottle, a positioning groove matching the positioning portion is provided on the bottle mouth.

[0008] In the above-mentioned novel plastic bottle, a sealing portion is arranged on the locking disk, and a sealing ring is arranged on the inner wall of the bottle mouth at a position in contact with the sealing portion.

[0009] Compared with the prior art, the utility model can achieve the locking effect through the locking device with only a slight rotation, thereby improving efficiency, making locking more convenient, and improving the overall sealing performance through the sealing ring and the sealing part.

DETAILED DESCRIPTION

[0014] 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.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the new plastic bottle comprises a bottle body 1 and a bottle cap 2. The top of the bottle body 1 has an integrally formed bottle mouth 3. The inner end of the bottle cap 2 is provided with a locking device 4. The locking device 4 consists of a locking disk 5 and a clamping disk 6. The locking disk 5 is arranged on the inner side of the clamping disk 6. Four clamping parts 7 are fixedly arranged on the locking disk 5. The four clamping parts 7 are each provided with a clamping protrusion 8. Four locking blocks 9 are fixedly arranged on the inner wall of the clamping disk 6. A locking groove 10 for locking and an unlocking groove 11 for unlocking are respectively provided on the inner wall of the clamping disk 6 and on both sides opposite to the locking block 9. The diameter of the unlocking groove 11 is larger than the diameter of the locking groove 10. A pressing strip 12 is provided on the inner walls of the four clamping parts 7 to further increase the connection strength between the bottle body 1 and the bottle cap 2. A positioning part 13 is provided on the inner wall of one clamping part 7.

[0016] To further elaborate, the locking plate 6 and the bottle cap 2 are integrally arranged, a rotating shaft 14 is arranged on the inner wall of the bottle cap 2 , and the locking plate 5 is arranged on the rotating shaft 14 and can rotate on the rotating shaft 14 .

[0017] To be more specific, a positioning groove 15 matching the positioning portion 13 is formed on the bottle mouth 3 .

[0018] During installation, first connect the positioning portion 13 with the positioning groove 15, and then rotate the bottle cap 2. The engaging protrusion 8 of the engaging portion 7 is squeezed and enters the locking groove 10 through the locking block 9. The diameter of the locking groove 10 is smaller than that of the unlocking groove 11, so the further it rotates into the locking groove 10, the tighter the lock is.

[0019] In further detail, a sealing portion 16 is provided on the locking disk 5, and a sealing ring 17 is provided on the inner wall of the bottle mouth 3 and at a position in contact with the sealing portion 16 to improve the sealing performance.

[0020] 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.

[0021] Although this article uses more terms such as bottle body 1, bottle cap 2, bottle mouth 3, locking device 4, locking disk 5, locking disk 6, clamping part 7, clamping protrusion 8, locking block 9, locking groove 10, unlocking groove 11, pressing strip 12, positioning part 13, rotating shaft 14, positioning groove 15, sealing part 16, sealing ring 17, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
