Description

Technical Field

[0001] The utility model belongs to the technical field of paper cups, and particularly relates to a piece of paper for producing a filter paper cup. Background Art

[0002] A paper cup is a container for holding beverages, such as milk tea, drinks, and fruit juices, or for entertaining guests, so it is usually discarded after one-time use. In the production and processing of paper cups, generally, a rectangular or fan-shaped ring piece of paper is used to form the cup body, and a circular piece of paper forms the cup bottom. When holding solid brewed beverages such as tea leaves or coffee that do not dissolve in water, the tea leaves may be accidentally drunk, causing certain troubles to users.

[0003] In the prior art, there is no filtering structure on the cup body formed by the piece of paper, which is very inconvenient when drinking solid brewed beverages that do not dissolve in water. To solve this problem, a filter net is placed on the cup mouth, but it needs to be cleaned after use, and the tea scale of the tea leaves is not easy to clean, making it very inconvenient to use. Therefore, a piece of paper with a filtering structure is needed. Summary of the Utility Model

[0032] A sector-shaped paper sheet 1, including a paper sheet layer 11 and a waterproof film layer 12;

[0033] A filter sheet 2, connected to the top of the sector-shaped paper sheet 1 through a tear mark 3 provided, and a plurality of filter holes 4 are provided on the filter sheet 2;

[0034] Among them, an avoidance notch 5 is provided on the filter sheet 2, a first insertion portion 6 is provided on the periphery of the avoidance notch 5, limiting notch openings 7 are provided on both sides of the first insertion portion 6, a first insertion seam 8 corresponding to the first insertion portion 6 is provided on one side of the filter sheet 2 where the avoidance notch 5 is located, and two positioning creases 9 are provided on the filter sheet 2. The positioning creases 9 include a head end and a tail end. The head ends of the two positioning creases 9 intersect, and the tail ends of the two positioning creases 9 are both located between the first insertion portion 6 and the first insertion seam 8.

[0035] In this technical solution, the fan-shaped paper sheet 1 can enclose a frustum-shaped cup body, and a cup bottom is provided at the bottom of the structure enclosed by the fan-shaped paper sheet 1 to achieve the function of holding water. The cup body formed by the fan-shaped paper sheet 1 can also enable paper cups made by using multiple of the present utility models to be stacked, saving storage space.

[0036] The fan-shaped paper sheet 1 includes a paper sheet layer 11 and a waterproof film layer 12. The waterproof film layer 12 is arranged on the inner side, and the paper sheet layer 11 is arranged on the outer side. The waterproof film layer 12 waterproofs the paper sheet layer 11.

[0037] The filter sheet 2 is connected to the top of the fan-shaped paper sheet 1 through a tear mark 3. The tear mark 3 can be composed of a dotted tear mark of a plurality of cutting seams arranged, so that the filter sheet 2 can be torn off along the tear mark 3. The filter sheet 2 is connected to the top of the fan-shaped paper sheet 1 through a tear mark 3. When the fan-shaped paper sheet 1 encloses the cup body, the filter sheet 2 is located at the cup mouth of the cup body and is bent into an arc shape, which is convenient for stacking multiple paper cups and saving storage space.

[0038] As Figure 2 shown, the filter sheet 2 is folded along the two positioning creases 9, so that the filter sheet 2 is folded into a conical funnel-shaped structure. Tea leaves can be placed in the funnel. A plurality of filter holes 4 are provided on the filter sheet 2 for filtering tea leaves. The water soaked with tea leaves leaks out from the filter holes 4 into the cup body.

[0039] After the filter sheet 2 is folded into a conical funnel-shaped structure, an avoidance notch 5 is provided on the filter sheet 2, so that the first insertion portion 6 can be inserted into the first insertion seam 8. The width of the first insertion portion 6 from the top end to the bottom end can gradually increase, so that the first insertion portion 6 can be smoothly inserted into the first insertion seam 8. The width of the bottom of the first insertion portion 6 is slightly larger than the width of the first insertion seam 8, so that the first insertion portion 6 can be clamped in the first insertion seam 8 to avoid falling off.

[0040] Limiting notch openings 7 are provided on both sides of the first insertion portion 6. The limiting notch openings 7 abut against the ends of the first insertion seam 8, further improving the stability of the first insertion portion 6 clamped in the first insertion seam 8.

[0041] When in use, the filter sheet 2 can be torn off along the tearing mark 3, the filter sheet 2 is folded into a funnel-shaped structure, and then the first insertion part 6 is snapped onto the first insertion seam 8 to fix the folded filter sheet 2. Then the fixed funnel-shaped filter sheet 2 is placed on the cup mouth of the cup body surrounded by the fan-shaped paper sheet 1. The top diameter of the funnel-shaped structure is larger than the cup mouth diameter to prevent it from falling into the cup body. Then the tea leaves are placed on the funnel-shaped structure formed by folding the filter sheet 2, water is poured in to submerge the tea leaves, and after soaking the tea leaves for a period of time, the funnel-shaped structure formed by folding the filter sheet 2 is taken out from the cup mouth of the cup body surrounded by the fan-shaped paper sheet 1.

[0042] Furthermore, waterproof films 21 are provided on both the inner and outer sides of the filter sheet 2.

[0043] In this technical solution, the waterproof film 21 can be made of polyethylene material. The waterproof film 21 can waterproof the inner and outer sides of the filter sheet 2, prevent the filter sheet 2 folded into a funnel shape from cracking and collapsing, and improve the service life of the filter sheet 2.

[0044] Embodiment 2:

[0045] This embodiment provides a paper sheet for producing a filter paper cup. In addition to including the technical solution of the above embodiment, it also has the following technical features.
