In order to solve the problem that the freshness of the edible liquid product in the memory cannot be intuitively prompted on the plastic bottle in the prior art, the embodiment provides a plastic bottle structure capable of prompting the quality guarantee period, as shown in fig. 1 and fig. 2. The plastic bottle structure comprises a bottle body 1, a bottle cap 2, a bottle label 3 and an electronic warning device 4. Wherein, the bottle cap 2 is arranged at the bottle mouth of the bottle body 1. The electronic warning device 4 is embedded on the bottle body 1 and can perform early warning prompt according to the production date and the quality guarantee period. The bottle label 3 is adhered to the bottle body 1 and completely covers the electronic warning device 4. By adopting the plastic bottle structure, the consumer can be intuitively reminded of the freshness of the edible liquid product in the memory without deliberately identifying the production date and the quality guarantee period on the plastic bottle, and the plastic bottle is suitable for the demands of various groups.

Specifically, the bottle body 1 is integrally formed by polymer resins such as polyester, polyethylene, polypropylene and the like, plasticizers, antioxidants, antibacterial agents, ultraviolet-resistant stabilizers, fillers, flame retardants and the like, and is subjected to blow molding, extrusion blowing or injection molding after being melted at high temperature. For example, the following composition is used:

composition 1: 50-60 parts of high-density polyethylene, 20-30 parts of low-density polyethylene, 0.3-0.5 part of antioxidant, 10-15 parts of calcium carbonate, 1.0-2.0 parts of stearic acid, 0.1-0.5 part of coupling agent, 0.8-1.2 parts of ultraviolet-resistant stabilizer, 0.5-1 part of antistatic agent and 1-2 parts of flame retardant.

Composition 2: 70-85 parts of polypropylene, 1-5 parts of POE resin, 0.1-0.5 part of antioxidant, 5-10 parts of calcium carbonate, 1.5-2.0 parts of zinc stearate, 0.1-0.4 part of coupling agent, 0.1-1.0 part of ultraviolet resistant stabilizer, 0.5-1 part of antistatic agent and 1-2 parts of flame retardant.

And 3: 50-80 parts of polyester, 5-10 parts of calcium carbonate, 1-10 parts of stearic acid, 3-6 parts of white oil, 1-2 parts of a coupling agent and 1-2 parts of an antioxidant.

The bottle body 1 processed by adopting the composition can meet the packaging requirement of edible liquid products.

The bottle body 1 has an inner region for containing an edible liquid product. The lower part of the bottle body 1 is cylindrical, the middle part of the side wall of the cylindrical area is recessed towards the inner area of the bottle body 1, and an installation cavity 11 with one surface open is formed.

In this embodiment, the mounting cavity 11 is formed in a rectangular shape so as to facilitate the bottle body molding die processing. Along the axial center direction perpendicular to the bottle body 1, the depth of the mounting cavity 11 is smaller than the radius of the bottle body 1, so that defects in blow molding, extrusion blowing or injection molding can be reduced, and the quality of the bottle body 1 can be ensured.

In this embodiment, all edges of the mounting cavity 11 are subjected to arc transition treatment, so as to reduce defects in blow molding, extrusion blowing or injection molding.

The bottle cap 2 is shown in figure 3, and is integrally formed by high-temperature melting and injection molding of polymer resins such as polyester, polyethylene, polypropylene and the like, plasticizers, antioxidants, antibacterial agents, ultraviolet-resistant stabilizers, fillers, flame retardants and the like. For example, the following composition is used: 50-60 parts of high-density polyethylene, 20-30 parts of low-density polyethylene, 0.3-0.5 part of antioxidant, 10-15 parts of calcium carbonate, 1.0-2.0 parts of stearic acid, 0.1-0.5 part of coupling agent, 0.8-1.2 parts of ultraviolet-resistant stabilizer, 0.5-1 part of antistatic agent, 1-2 parts of flame retardant and 0-5 parts of color master batch.

The bottle cap 2 is covered on the bottle mouth of the bottle body 1 to seal the inner area of the bottle body 1.

The electronic warning device 4 is integrally fixed in the mounting cavity 11 and used for prompting the quality guarantee period. The electronic warning device 4 comprises a cover plate 41, an isolation cabin 42 and an electronic integrated part 43.

The cover 41 is entirely made of polymer resin such as polyester, polyethylene, polypropylene, etc., plasticizer, antioxidant, antibacterial agent, ultraviolet resistant stabilizer, filler, flame retardant, etc., and is injection molded after being melted at high temperature. The cover plate 41 is arcuate and mates with the open end of the mounting cavity 11. After the electronic warning device 4 is clamped into the mounting cavity 11, the cover plate 41 closes the open end of the mounting cavity 11. The outer side surface of the cover plate 41, i.e. the surface facing the outside of the bottle body 1, is flush with the outer side surface of the side wall of the bottle body 1 to form a complete curved surface, so that the appearance is complete and attractive. On the one hand, the cover plate 41 closes the mounting cavity 11 and protects the other parts of the electronic warning device 4. On the other hand, after the cover plate 41 closes the open end of the installation cavity 11, the outer wall of the bottle body 1 is complete, and the structural stability is improved as a whole. In this embodiment, in order to improve the connection reliability between the cover plate 41 and the open end of the mounting cavity 11, the edge of the cover plate 41 is connected with the bottle body 1 by adopting a high-temperature spot welding mode, for example, welding by adopting an electric welding gun, heating the welding head to 200-250 ℃, lightly touching the connection position between the edge of the cover plate 41 and the bottle body 1, so as to slightly melt, and forming an adhesive connection after cooling.

The isolation bin 42, as shown in fig. 4, is mounted on the inside surface of the cover plate 41. The isolation bin 42 is of a rectangular structure, is hollow, and is open at the bottom surface and the open end faces the bottle bottom direction of the bottle body 1. Rectangular frame-shaped clamping grooves 421 are formed on the inner side of the inner top surface of the isolation bin 42 for clamping and fixing the electrical sub-assembly 43. The isolation bin 42 is used for secondary separation protection of the electrical sub-assembly 43. I.e. liquid flows along the bottle body 1 into the mounting cavity 11, the isolation bin 42 can still avoid the liquid from contacting the electronic integrated part 43.

In this embodiment, the peripheral dimension of the isolation bin 42 is matched with the installation cavity 11, that is, after the isolation bin 42 is inserted into the installation cavity 11, the surface of the outer wall of the isolation bin 42 except the surface connected with the cover plate 41 and the surface with the opening is attached to the corresponding surface of the installation cavity 11. After the isolation bin 42 is in contact with the inside of the installation cavity 11, the installation cavity 11 is filled, so that the overall reliability can be improved.

In this embodiment, further, before the isolation bin 42 is installed in the installation cavity 11, a proper amount of adhesive may be dispensed on the outer wall of the isolation bin 42 to improve the fixing reliability between the isolation bin 42 and the installation cavity 11, so as to prevent the isolation bin 42 from being separated from the installation cavity 11 when the bottle body 1 vibrates.

An electrical sub-assembly 43, removably mounted within the compartment 42, is provided for indicating the shelf life of the edible liquid product contained in the bottle. The electrical subassembly 43 includes a power module, a microprocessor module, a timing module, an LED lamp module, and a buzzer module. The power module, the microprocessor module, the timing module, the LED lamp module and the buzzer module are integrally mounted on a PCB 431, and the logic connection structure of the above modules is shown in fig. 5. The power module supplies power to the microprocessor module, the timing module, the LED lamp module and the buzzer module. The microprocessor module is communicated with the timing module, and the microprocessor module is used for controlling the actions of the LED lamp module and the buzzer module. One end of the PCB 431 is inserted into the clamping groove 421, and the opposite end is positioned inside the open end of the isolation bin 42. The electrical sub-assembly 43 is of an integrated design and is quick to install. The microprocessor module is internally provided with a control program and controls the LED lamp module and the buzzer module to work according to a preset instruction. For example, a liquid product has a shelf life of 6 months. After the product is produced and filled, the microprocessor module starts to work. Program setting is built in a microprocessor module: (1) the LED lamp module flashes for 1 time every 4 hours within 1-3 months after production of the product; (2) the LED lamp module flashes for 1 time every 2 hours within 4-5 months after production of the product; (3) the LED lamp module flashes for 1 time every 1 hour within 5-5.5 months after the production of the product; (4) within 5.5-6 months after the production of the product, the LED lamp module flashes for 1 time every 0.5h, and the buzzer module sounds for 1 time every 0.5 h; (5) and after the production of the product exceeds the quality guarantee period, the buzzer module continuously sounds.

In this embodiment, an edge of one end of the PCB 431 inserted into the card slot 421 is formed with a protrusion, and the corresponding card slot 421 is recessed or opened. After the PCB 431 is inserted into the card slot 421, the protrusions are engaged with the corresponding recesses or openings, thereby improving the reliability of the installation of the electrical component 43 and preventing the detachment under vibration of the bottle 1.

The bottle label 3 is adhered to the bottle body 1 and completely shields the electronic warning device 4. The bottle label 3 can protect the electronic warning device 4 and further prevent the electronic warning device 4 from falling out.
