Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottles, in particular to a double-layer composite plastic bottle. Background Art

[0002] Polylactic acid is a new environmentally friendly biodegradable material developed in recent years. Its raw materials are renewable natural resources, and it has low energy consumption and good environmental friendliness, biocompatibility, mechanical properties and processing properties. It is an ideal petroleum substitute product with broad application prospects. It can be made into plastic bottles.

[0003] Publication No. CN103482167A discloses a double-layer composite plastic bottle comprising a bottom, a body, a neck, and a mouth. The bottom, body, neck, and mouth are connected in sequence from bottom to top. The body is formed by spirally winding a plastic tube. The pitch of the spiral of the body is less than the sum of the outer diameter and the wall thickness of the plastic tube.

[0004] When the device is in use, the water source inside the spiral tube above the device is heavy, which makes the device heavy when not in use. In addition, people can only drink one water source when in use, which makes the space utilization rate of the plastic bottle low. Therefore, we propose a double-layer composite plastic bottle. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a double-layer composite plastic bottle.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, the shape of the rotating drinking water device is conical, an external thread is provided on the outer side of the rotating drinking water device, an internal thread hole is provided on the inner side of the sealing rotary cover, and the external thread and the internal thread are engaged with each other.

[0009] By adopting the above technical solution, the shape of the rotating drinking water device is convenient for people to drink, the sealing screw cap can seal the rotating drinking water device to prevent water from flowing out, and the control panel can seal and cover the plastic bottle when not drinking.

[0010] Preferably, a locking block is fixedly mounted on one side of the sliding block, and a control device is fixedly mounted on the other side of the sliding block.

[0011] By adopting the above technical solution, the anti-scalding plastic shell can be connected to the bottom of the fixed shell through the cooperation of the connecting block and the locking block, making the connection more convenient and preventing people from getting burned when holding the anti-scalding plastic shell.

[0012] Preferably, the control device is C-shaped, a threaded hole is provided on one side of the fixed shell and the control device, a screw rod is threadedly installed on the inner side of the threaded hole, and a knob is fixedly installed on one end of the screw rod.

[0013] By adopting the above technical solution, the C-shaped control device is convenient for controlling multiple sliding blocks. Since the sliding blocks can limit the control device, the control device can only slide after the screw rod rotates.

[0014] Preferably, a plurality of water outlets are provided on the top of the control panel, a water outlet hole is provided on the top of the plastic bottle, and the water outlets abut against the water outlet hole.

[0015] By adopting the above technical solution, the control panel can control whether the plastic bottles can dispense water at the same time or individually, so that people have a wider range of choices when drinking.

[0016] Preferably, connecting grooves are provided at the four corners of the bottom of the fixing shell, and the outer diameter and spacing of the connecting blocks are respectively the same as the outer diameter and spacing of the connecting grooves.

[0017] By adopting the above technical solution, after one of the connection blocks corresponds to the connection groove during positioning, the remaining connection blocks can be quickly positioned and installed.

[0018] Preferably, through slots are provided on the left and right sides of the fixed shell, and the sliding blocks are slidably mounted on the inner sides of the through slots.

[0019] By adopting the above technical solution, the through groove makes it easier for the control device to drive the multiple sliding blocks to slide, making the connection and disassembly of the device more convenient.

[0020] Preferably, a locking groove is provided on one side of the connecting block, and the locking block fits in the locking groove.

[0021] By adopting the above technical solution, the locking groove makes it easy for the locking block to lock the connecting block after sliding, making the connection more convenient and quick and not easy to disengage.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The device can add different water sources to the inner side of the plastic bottle, set the fixed shell on the top of the plastic bottle, and connect it with the locking block through the connecting block above the scald-proof plastic shell. The control knob drives the screw rod to rotate, so that the screw rod drives the control device to slide, so that the connection between the connecting block and the locking block is relatively stable and not easy to separate. When drinking, the person can rotate the drinking device, so that the rotating drinking device can drive the control panel to rotate after rotation, so that the person can drink the water sources inside the two plastic bottles at the same time, or drink them separately, so that the device can be used with different drinks.
