Description

Technical Field

[0001] The utility model relates to the technical field of polyester bottles, in particular to a polyester bottle with a barrier liquid level. Background Art

[0002] A barrier-type polyester bottle is a container used to store liquids, typically made of polyester. It provides a barrier function, effectively preventing volatilization, leakage, or deterioration during storage. These bottles are commonly used to store liquids such as gasoline, diesel, and lubricating oil.

[0003] During the patent application process, a search revealed a Chinese patent with the number CN216469221U: A novel polyester bottle comprising a bottle body, a bottle base, and a bottle cap. The patent features: the bottle base is provided with several layers of annular anti-slip pads, the outer surface of the bottle body is provided with an anti-slip structure, a bottle neck is fixedly mounted on the upper end of the bottle body, a fixing ring is fixedly mounted above the bottle neck, the upper end of the fixing ring is rotatably connected to the bottle cap, the anti-slip structure is a ring-shaped groove structure fixedly mounted on the bottle body, and a water-absorbing structure is provided on the upper end of the fixing ring and the bottle cap. While this device has a good waterproof effect, when storing some volatile liquids, because the stored liquid is not fully filled inside the polyester bottle, additional space is left between the liquid and the bottle cavity. Volatile gases are present in this space, causing the liquid to spill when the bottle is opened. Furthermore, the reserved space in the bottle cavity also increases the probability of deterioration of some liquids. Therefore, improvements are needed. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the utility model provides a polyester bottle with a barrier liquid level, which solves the problem that when the polyester bottle is not full, the volatile liquid will spill when the bottle is opened, and the reserved space in the bottle cavity will also increase the deterioration of some liquid to a certain extent.

[0005] The utility model also provides the above-mentioned polyester bottle with barrier liquid level, comprising: a bottle body, a bottle cap rotatably connected to the upper side of the bottle body, a compression rod connected to the inner thread of the bottle cap, the upper end of the compression rod fixedly connected to the limiting plate, the lower end of the compression rod is located in the bottle body and slidably connected to a piston, a sealing ring and a wear-resistant ring are sleeved on the outer side of the piston, a pipe is provided in the compression rod, the pipe is communicated with the limiting plate and the piston, a bottle stopper is provided on the upper side of the limiting plate, and the bottle stopper is adapted to the pipe.

[0006] An internal thread is provided on the inner side of the bottle cap, and an external thread is provided on the outer side of the compression rod, and the internal thread is adapted to the external thread.

[0007] The outer side of the bottle body is sleeved with an anti-slip sleeve.

[0008] The sealing ring and the wear-resistant ring are both made of rubber.

[0009] A spring belt is provided between the bottle body and the bottle stopper.

[0010] The opening of the pipeline increases in size from top to bottom.

[0011] The utility model has the following beneficial effects:

[0012] In the utility model, a bottle cap, a compression rod and a piston are arranged in the bottle. When in use, the bottle cap is opened and the liquid is poured out from the bottle through the pipeline. Then the bottle cap is rotated to make the compression rod drive the piston to descend and discharge the gas through the pipeline until the stored liquid stops entering the pipeline. It is best to just block the pipeline with the bottle cap, which is convenient to operate.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0021] Reference Figure 1-4The embodiment of the utility model is a polyester bottle with a barrier liquid level, which includes a bottle body 1, an anti-slip sleeve 11 is sleeved on the outer side of the bottle body 1, and the anti-slip sleeve 11 is made of rubber. A bottle cap 2 is rotatably connected to the upper side of the bottle body 1, and the outer side of the bottle cap 2 is engraved with anti-slip grooves. The bottle cap 2 is internally threaded and connected to a compression rod 3. The inner side of the bottle cap 2 is provided with an internal thread 21, and the outer side of the compression rod 3 is provided with an external thread 31. The internal thread 21 is adapted to the external thread 31. By rotating the bottle cap 2, the compression rod 3 can be driven to move up and down;

[0022] When the bottle is in the open position, the piston 6 is moved downwards to release the gas, which is then forced to move upwards to release the gas.

[0023] Working principle: When in use, first pull the limit plate 4 upwards, and the limit plate 4 drives the piston 6 to move upward, thereby driving the bottle cap 2 to rotate. When the piston 6 moves to the top of the bottle body 1, it stops, and the storage liquid is injected into the bottle through the pipe 32 and stored; when it needs to be used, open the bottle stopper 5 and pour the liquid out of the bottle through the pipe 32. At this time, a cavity is generated in the part of the bottle where the liquid is discharged. The gas in the cavity will cause the liquid to deteriorate to a certain extent. Therefore, the bottle cap 2 is rotated to make the compression rod 3 drive the piston 6 to descend, and the gas is discharged through the pipe 32 until the storage liquid enters the pipe 32 and stops. It is best to block the pipe 32 with the bottle stopper 5, which is convenient to operate.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
