Definitions

  • the present invention relates generally to the structure of paper cups, and more particularly to an improved structure of a paper cup which forms a perfect plane at the mouth of the cup and is convenient for quick separation and disposal after use.
  • Disposable containers are commonly made of plastic or paper materials. Although plastic containers with a single-layer structure have the advantages of easy manufacture, lower cost and better leak resistance, they are not suitable for heat preservation. The manufacturing of paper containers requires more complex process and higher cost, but their leakproof effect and structural strength are not as good as that of plastic containers. Therefore, in order to obtain the desired insulation effect, it is necessary to adopt a multi-layer or thicker design, or add a foam insulation layer, that may lead to an extremely high cost.
  • the main object of the present invention is to provide an improved structure of paper cups, a plastic fastener is combined with a paper cup, and the plastic fastener forms an extension piece at the curled edge of the cup mouth, or the body of the paper cup is provided with an easy-to-tear strip, so as to achieve the effect of easy separation and recycling.
  • the inventor has designed an improved structure of paper cups, including: A plastic fastener and a paper cup; the plastic fastener and the mouth of the paper cup are formed with an outwards curled edge respectively, particularly, the curled edge of the plastic fastener is a little larger than the paper cup and covers the curled edge of the paper cup, and the top surface of the curled edge forms a flat surface, so that the plastic fastener is integrated with the paper cup through the curled edge, and the plastic fastener is a plane on the top surface of the cup mouth, and the lower edge of the plastic fastener extends downwards to the bottom surface of the paper cup to form an airtight space, the curled edge of the plastic fastener is provided with an extension piece, and the lower edge of the paper cup is provided with some small holes.
  • the extension piece on the curled edge at the mouth of the film plastic inner cup can be formed in any geometric shape, including but not limited to: Any of teardrop, convex, circular, polygonal and rectangular.
  • an easy-to-tear strip is provided on the surface of the body of the paper cup.
  • the plastic fastener can be made of any one or a composite of Polypropylene (PP), Polystyrene (PS), Poly Lactic Acid (PLA), Polyethylene (PE), Polyethylene Terephthalate (PET).
  • PP Polypropylene
  • PS Polystyrene
  • PLA Poly Lactic Acid
  • PE Polyethylene
  • PET Polyethylene Terephthalate
  • the paper cup is made of recycled paper.
  • the improved structure of paper cups (1) comprises: a plastic fastener (2) and a paper cup (3); wherein the plastic fastener (2) and the mouth of the paper cup (3) are formed with an outwards curled edge (21, 31) respectively, the curled edge of the plastic fastener (2) is a little larger than the curled edge (31) of paper cup (3) and covers the curled edge (31) of the paper cup (3), so that the plastic fastener (2) is integrated with the paper cup (3) through the curled edges (21, 31), and the top surface of the curled edge (21) of the plastic fastener (2) forms a flat surface (F), the lower edge of the plastic fastener (2) extends downwards as a plane (20) to the bottom surface of the paper cup (3) to form an airtight space, the curled edge (21) of the plastic fastener (2) is formed with an extension piece (22) in any geometric shape towards the
  • the ratio of the paper to plastic as raw materials of the improved structure of paper cups (1) is 7: 3 (i.e. the weight percentage is 70%: 30%), so that the paper cup (3) has better structural strength; and the proportion of paper is relatively high, so the recycled paper is selected as the best raw material, both environmental protection and cost are considered.
  • the part in contact with the liquid is a plastic fastener (2), so it is unnecessary to worry about food hygiene or safety.
  • plastic fastener (2) including but not limited to: Any one or a composite of Polypropylene (PP), Polystyrene (PS), Poly Lactic Acid (PLA), Polyethylene (PE), Polyethylene Terephthalate (PET).
  • PP Polypropylene
  • PS Polystyrene
  • PLA Poly Lactic Acid
  • PE Polyethylene
  • PET Polyethylene Terephthalate
  • the extension piece (22) on the curled edge (21) of the plastic fastener (2) can be formed in any geometric shape, including but not limited to: teardrop-shaped, convex, circular, polygonal and rectangular.
  • the curled edge (21) of the plastic fastener (2) is unrolled by automatic processing before the paper cup (3) is inserted in, so that the curled edge (21) of the plastic fastener (2) covers the curled edge (31) of the paper cup (3), which are superimposed on each other, and the plane (F) formed by the plastic fastener (2) can completely avoid the liquid leak and residual stains resulted from the height difference of the mouth of a paper cup (3).
  • the small holes (32) in the circumferential surface near the lower edge of the paper cup (3) can discharge hot air timely and conveniently.
  • the improved structure of paper cups (1) of the present invention directly combines the plastic and paper materials without gluing, the assembly is performed quickly.
  • the plastic fastener (2) can be easily and quickly separated from the paper cup (3) by using the extension piece (22), contributing to garbage sorting and recycling.
  • FIGs. 7 ⁇ 9(A)(B)(C) disclose the improved structure of paper cups in a preferred embodiment of the present invention, including : A plastic fastener (2) and a paper cup (3); wherein the plastic fastener (2) and the mouth of the paper cup (3) are formed with an outwards curled edge (21, 31) respectively, the curled edge (21) of the plastic fastener (2) is a little larger than the curled edge (31) of paper cup (3) and covers the curled edge (31) of the paper cup (3), so that the plastic fastener (2) is integrated with the paper cup (3) through the curled edges (21, 31), and the top surface of the curled edge (21) of the plastic fastener (2) forms a flat surface (F), the lower edge of the plastic fastener (2) extends downwards as a plane to the bottom surface of the paper cup (3) to form an airtight space, the curled edge (21) of the plastic fastener (2) is formed with an extension piece (22) in any geometric shape towards the bottom, the circumferential surface of the lower edge
