Definitions

  • the description pertains to the technical field of packaging, and particularly relates to a snap-fitting structure of paper and plastic container.
  • Beverage cups generally use polyester (PET), polyethylene (PE) or polypropylene (PP) as a raw material, which is heated at a high temperature after the addition of an organic solvent and is then molded by method of blow molding, extrusion or injection molding in a mold of plastics.
  • PET polyester
  • PE polyethylene
  • PP polypropylene
  • a snap-fitting structure includes a container and a cover each made of paper, plastic, or a combination thereof.
  • the cover is configured to be disposed over and snap-fitted to the container.
  • the container comprises a container body and a clamping portion extending out of the edge of the container body.
  • the clamping portion comprises a connecting portion connected to the container body, and a clamp ring extending out of the connecting portion.
  • the included angle between the contour line of the connecting portion and the central axis of the body is an acute angle
  • the contour line of the clamp ring is parallel to the central axis of the body.
  • the cover comprises a cover bottom and a cover wall extending out of the edge of the cover bottom.
  • a flange is disposed on the inner side wall of the cover wall.
  • the outer diameter of the clamp ring on the container body is equivalent to the inner diameter of the cover wall.
  • the flange and the cover bottom are arranged at an interval, and the clamp ring on the container is positioned between the flange and the cover bottom when the cover is disposed over the container.
  • the flange and a free end of the cover wall are arranged at an interval.
  • the contour line of the flange is arc-shaped.
  • the distance from the side wall of the container body to the clamp ring is equal to the height of the arc of the flange.
  • the height of the clamp ring is equal to the minimum distance from the flange to the cover bottom.
  • the outer diameter of the clamp ring is equivalent to the inner diameter of the cover wall, the clamp ring deforms under the pressing of the flange.
  • the clamp ring restores to its original state or is still in a deformed state to abut against the cover wall, and is clamped between the cover bottom and the flange, such that the container and the cover are snap-fitted together and are not disengaged without an external force.
  • FIG. 1 is a structural schematic view of a snap-fitting structure of paper and plastic container.
  • FIG. 2 is a cross-sectional structural schematic view of the snap-fitting structure of paper and plastic container in FIG. 1 .
  • FIG. 1 and FIG. 2 are structural schematic views of a snap-fitting structure of paper and plastic container including a container or cup 10 and a cover 20 configured to be snap-fitted to the container 10 . It can be understood that the container 10 and the cover 20 both can be pressed from paper pulp or paper and plastic material.
  • the container 10 comprises a container body 11 and a clamping portion 12 extending out of the edge of the container body 11 . It is conceivable that the container 10 may further comprise some other functional structures, such as a cup handle part and an ornamental part, which are technologies known to those skilled in the art, and will not be described in detail here.
  • the container body 11 is used to hold various items, such as liquid and suspension, which is an existing technology and will not be described in detail here.
  • the clamping portion 12 comprises a connecting portion 121 connected to the container body 11 , and a clamp ring 122 extending out of the connecting portion 121 .
  • the included angle between the contour line of the connecting portion 121 and the central axis of the container body 11 is an acute angle
  • the contour line of the clamp ring 122 is parallel to the central axis of the container body 11 .
  • the cover 20 comprises a cover bottom 21 , a cover wall 22 extending out of the edge of the cover bottom 21 , and a flange 23 arranged on the inner side wall of the cover wall 22 . It is conceivable that the cover 20 may further comprise some other functional structures, such as a lifting handle and a jack.
  • the cover bottom 21 is a technology known to those skilled in the art, and will not be described in detail here.
  • the flange 23 and the cover bottom 21 are arranged at an interval. In the direction along the central axis of the container body 11 , the height of the clamp ring 122 is smaller than or equal to the minimum distance from the flange 23 to the cover bottom 21 . When the cover 20 is disposed over the container 10 , the clamp ring 122 is clamped between the flange 23 and the cover bottom 21 .
  • the contour line of the clamp ring 122 is parallel to the central axis of the container body 11 .
  • the flange 23 and a free end of the cover wall 22 are arranged at an interval.
  • the contour line of the flange 23 can be arc-shaped.
  • the contour line of the flange 23 can be in other shapes, too, such as wave and teeth, which can be selected according to the actual need.
  • the distance from the side wall of the container body 11 to the clamp ring 122 is equal to the height of the arc of the flange 23 .
  • the container 10 and the cover 20 have the clamping portion 12 and the flange 23 respectively.
  • the clamp ring 122 deforms under the pressing of the flange 23 .
  • the clamp ring 122 restores to the original state or is still in a deformed state to abut against the cover wall 22 , and is clamped between the cover bottom 21 and the flange 23 , such that the container 10 and the cover 20 are fitted in a covering manner and are not disengaged without an external force.
