Description

Technology Field

[0001] The present invention relates to a microplastic filtration device for PET bottles. Background Technology

[0002] Generally, PET bottles containing bottled water are stocked in supermarkets, allowing consumers to purchase and consume the products they want.

[0003] Meanwhile, one of the most problematic pollutants in recent times is microplastics. As discarded plastics decompose, they are released as tiny particles; these microplastics can be absorbed by plants and animals, seep into the soil, and enter the groundwater along with rainwater.

[0004] Microplastics that have entered groundwater are not only invisible but also remain in the water sources of commercially sold bottled water; consequently, consumers who purchase and drink this water end up consuming it, inevitably leading to its accumulation in the human body and causing health problems.

[0005] The size of microplastics found in bottled water varies. According to research, up to 10,000 plastic fragments are found in a single bottle of water.

[0006] It was found that an average of 10.4 microplastic particles with a size of 100㎛ (1㎛ is one millionth of a meter) were detected per liter.

[0007] Since the thickness of a hair is approximately 50 to 100 µm, microplastics of this size are ultrafine particles that cannot be distinguished with the naked eye.

[0008] According to animal studies, marine organisms exposed to microplastics entering the ocean have been found to experience slowed growth or problems with reproductive capacity.

[0009] There are also reports that exposure to carcinogens emitted from plastics can lead to a decrease in sperm count and autism.

[0010] Accordingly, various filtration devices have been proposed to prevent the inhalation of microplastics.

[0011] Korean Patent Application No. 10-2020-0038446 discloses a 'microplastic filter lid'.

[0012] Looking at the prior art, it includes a cap coupling part coupled to a bottle cap, an injection port coupling part coupled to a bottle inlet, and a filter part interposed between the cap coupling part and the injection port coupling part to filter liquid.

[0013] However, conventional technology had poor filtering performance and had the disadvantage of being difficult to filter multiple PET bottles at once. Prior art literature

[0027] The microplastic filtration device for PET bottles according to the present invention is,

[0028] A support member (100) composed of a support wall (120) supported on the ground and a horizontal plate (140) formed on the upper part of the support wall (120), and having an insertion hole (142) formed therein,

[0029] A storage container (200) placed at the bottom of the base (100), and

[0030] A plurality of side walls (320) are arranged on four sides to form an insertion part into which a PET bottle (2) is inserted upside down, and a mounting part (300) formed on the upper part of the insertion hole (142) of the support part (100), and

[0031] It is configured to include a filter part (400) that is inserted into an insertion hole (142) and connected to the bottle opening (20) of a PET bottle (2).

[0032] The support member (100) has support walls (120) erected vertically on both sides, and a horizontal plate (140) is attached to the upper part of the support walls (120) on both sides to form a space into which a storage container (200) capable of holding water is inserted.

[0033] An insertion hole (142) is formed in the horizontal plate (140), and the insertion hole (142) is formed larger than the diameter of the bottle opening (20) of the PET bottle (2) so that the bottle opening (20) can be fitted into the insertion hole (142).

[0034] The storage container (200) can be a clean container that can receive and store water falling from the filter unit (400).

[0035] The mounting part (300) is formed in a rectangular shape and is suitable if it is of a size that allows one PET bottle (2) to be fitted and connected.

[0036] The side walls (320) placed on the four sides are formed in a fixed rectangular shape.

[0037] Meanwhile, referring to FIG. 7, the mounting part (300') according to another embodiment may have a structure in which the four side walls (320) are each connected by a spring (S) so that it can be extended and retracted to accommodate not only small-sized PET bottles but also large-sized PET bottles.

[0038] Referring to FIG. 3, the filter unit (400) comprises a main body (420) having a screw portion (422) formed to be fastened to a bottle inlet (20) and a storage portion formed inside, and

[0039] It is composed of a filter body (440) that is inserted into the storage part by penetrating and coupled inside the main body (420) and inserted into the inner side of the bottle opening (20) to allow water to pass through.

[0040] The above filter body (440) comprises a wick body (442) having a screw thread (441) formed on its outer surface that is screw-coupled to the bottom plate of the main body (420), and

[0041] It is configured to include a lower surface member (443) inserted into the interior of the above-mentioned wick body (442) and positioned on the outside of the filter section (400), charcoal (444) stacked on the upper part of the lower surface member (443), and an upper surface member (445) stacked on the upper part of the charcoal (444) through which the raw water inside the PET bottle (2) is first introduced.

[0042] The lower surface member (443) or the upper surface member (445) is a fibrous material formed by compressing the surface, and the charcoal (444) is a lump of charcoal formed by compression to have fine pores.

[0043] Therefore, microplastics are filtered out while passing through the upper surface member (445), charcoal (444), and lower surface member (443).

[0044] Meanwhile, referring to FIG. 6, the filtration unit (400') may be formed by forming a plurality of holes (422') in the bottom plate of the main body (420') and attaching a filter body (440') to each of the plurality of holes (422').

[0045] The filter body (440') may be a rod-shaped material made of cotton.

[0046] Therefore, the water inside the PET bottle (2) can be filtered by passing through multiple filter bodies (440') simultaneously, thereby further accelerating the filtration speed.

[0047] Meanwhile, referring to FIG. 4, according to another embodiment (A2),

[0048] The mounting section (300) is formed by dividing a storage space (360) in which a plurality of PET bottles (2) are stored, by forming a partition (350) inside a plurality of side walls (320).

[0049] The support member (100) that supports the mounting member (300) is

[0050] The side wall (320) is formed by the inner wall (322) and the outer wall (324) being in close contact, and

[0051] A horizontal plate (140) is connected to the upper part of the inner wall (322), and a height adjustment part (350) for adjusting the height of the inner wall (322) is included.

[0052] The height adjustment unit (350) includes a plurality of height adjustment holes (3240) formed longitudinally in the outer wall (324) and a fixing member (352) that penetrates the height adjustment holes (3240) and is coupled to the inner wall (322).

[0053] Therefore, when multiple PET bottles (2) are stored in the mounting section (300) and water is filtered from multiple PET bottles (2) simultaneously and discharged into the lower storage container (200), the discharge volume increases, so it is necessary to install a large storage container (200), and accordingly, the height of the support section (100) is raised so that the large storage container (200) can be stored.

[0054] Although described in relation to preferred embodiments, those skilled in the art will readily recognize that various modifications and variations are possible without departing from the essence and scope of the invention, and it is obvious that all such changes and modifications fall within the scope of the appended claims.
