Definitions

  • the present invention belongs to the technical field of articles for daily use, and relates to a paper cup, and more particularly, to a nested paper cup.
  • Disposable paper cups have been widely used in various occasions, and the paper cups are nested and overlapped together for storage, which can save a lot of storage and transportation space.
  • the nested and overlapped paper cups there is a certain interval between a bottom of a previous paper cup and a bottom of a next paper cup, some instant foods, such as milk powder, tea leaves and the like may be stored in the interval.
  • a space formed by the interval is very small, and the interval is often minimized to the greatest extent in design to save a storage space. Therefore, the existing disposable paper cups are difficult to meet this demand.
  • solutions in the field of food packaging may be referred, such as food product package having nested cup and cup holder of U.S. Patent Publication No. US2005/0220939A1 .
  • two cups with different sizes are adopted, an inner cup is nested in an outer cup, the inner cup is suspended in the outer cup through a convex edge of a cup rim, and a height of the inner cup is smaller than that of the outer cup, so that an enough food storage space is formed between a bottom of the inner cup and a bottom of the outer cup.
  • a large storage space is capable of being implemented by nesting and overlapping such two cups with different sizes, but only one cup is actually used when the two cups with different sizes are used, and the other cup only increases an anti-scalding effect, which will lead to a high consumption cost, thus being not conducive to saving resources.
  • the above solution may be used in the field of disposable paper cups, but according to the above solution, the paper cups are made of plastic materials. After using paper materials, a concave-convex supporting structure on a side portion becomes very difficult in technology, and a supporting strength is also a factor to be considered.
  • the present invention provides a nested paper cup, and the technical problem to be solved is how to adjust a food storage space in the nested paper cup.
  • a nested paper cup comprising a cup body made of a paper material, a bottom of the cup body being provided with an annular foot, characterized in that a liner is arranged on an inner side of the cup bottom of the cup body, a bottom of the liner abuts against the cup bottom of the cup body, a side wall of the liner abuts against an inner side wall of the cup body and a top of the side wall of the liner protrudes from an inner side wall of the cup body, when two identical cup bodies above are nested along up and down direction, the internally nested cup body is an upper cup body, the cup body located outside the upper cup body is a lower cup body, and a annular foot of the upper cup body abuts against the top of the liner in the lower cup body and a space is formed by the annular foot and the side wall of the liner.
  • a larger food storage space may be provided between a bottom of the upper cup body and a bottom of the lower cup body.
  • the liner in the nested paper cup above, is made of a paper material and comprises the bottom and an annular side wall formed by bending along a crease of the bottom, and the annular side wall abuts against an inner peripheral side wall of the cup body.
  • An angle of the annular side wall after bending is larger than an angle between a side wall of the cup body and the cup bottom, and after putting the liner into the cup body, the annular side wall has a small amount of elasticity, so that the annular side wall abuts against the inner peripheral side wall of the cup body.
  • the liner is formed by pressing a circular paperboard, after pressing, the annular side wall of the liner forms a plurality of folds protruding inwardly in a vertical direction, and the folds are arranged in a circumferential direction.
  • the folds increase a contact area between the top of the liner and the foot, and play a role of a reinforcing rib.
  • the liner in the nested paper cup above, includes the bottom and a plurality of supporting sheets formed by bending along a crease of the bottom, the supporting sheets abut against an inner peripheral side wall of the cup body, and at least one fold protruding inwardly in a vertical direction is arranged on each supporting sheet.
  • an interval or an overlapped state is formed between the supporting sheets.
  • a supporting effect can be increased.
  • the bottom of the liner is circular or strip-shaped, and a bottom surface of the liner is adhered to an inner side of the cup body. Not only a strength of the bottom can be increased to prevent the bottom from being deformed or damaged by food, but also a sealing property can be improved to prevent liquid leakage.
  • the cup body has a single-layer structure, and an outer peripheral wall of the upper cup body is capable of abutting against an inner side wall of the lower cup body.
  • the single-layer cup body has a certain thickness, and after the upper cup body and the lower cup body are nested and overlapped up and down, the upper cup body and the lower cup body are capable of being clamped and are not easy to be separated.
  • the cup body has a double-layer paper wall structure, which includes an outer layer paper wall and an inner layer paper wall, the outer layer paper wall is wrapped on an outer side of the inner layer paper wall, and after the upper cup body and the lower cup body are nested and overlapped up and down, the outer layer paper wall of the upper cup body (1a) is capable of abutting against the inner layer paper wall of the lower cup body (1b).
  • the first solution of the cup body is further improved, and a thickness of the cup body is increased through the outer layer paper wall to increase a clamping tightness between two cup bodies.
  • a plurality of outwardly convex portions are arranged on an outer peripheral wall of the cup body, and the convex portions of the upper cup body abut against an inner side wall of the lower cup body. A clamping degree between two cup bodies is further increased through the outwardly convex portions.
  • the convex portions have a hollow structure, and the convex portions are strip-shaped, dot-shaped or annular.
  • the hollow structure not only can implement an anti-scalding function, but also has certain elasticity, so that different height differences can be applied in front of and behind the two cup bodies.
  • the nested paper cup has the following advantages.
  • a nested paper cup includes a cup body 1 made of a paper material, and a bottom of the cup body 1 is provided with an annular foot 2.
  • a plurality of outwardly convex portions 3 are arranged on an outer peripheral wall of the cup body 1, the convex portions (3) have a hollow strip-shaped structure.
  • the cup body 1 has a double-layer paper wall structure, which includes an outer layer paper wall and an inner layer paper wall. The outer layer paper wall is wrapped on an outer side of the inner layer paper wall, the outer layer paper wall of the cup body 1 is provided with strip-shaped outwardly convex portions 3 by pressing, and the convex portions 3 have a hollow strip-shaped structure.
  • the convex portions 3 of the upper cup body 1a abut against the inner side wall of the lower cup body 1b.
  • the hollow structure of the convex portions 3 not only can implement an anti-scalding function, but also has certain elasticity, so that different height differences can be applied in front of and behind the two cup bodies 1.
  • the convex portions 3 may have a dotted or annular structure.
  • a bottom of an inner side of the cup body 1 is provided with an annular liner 4, a bottom of the liner 4 is supported on the bottom of the cup body 1, and a bottom surface of the liner 4 is adhered to the inner side of the cup body 1 to form a double-layer bottom structure.
  • a top of the liner 4 protrudes from an inner side wall of the cup body 1.
  • the liner 4 is made of a paper material and includes the bottom 41 and an annular side wall 42 formed by bending along a crease of the bottom 41, and the annular side wall 42 abuts against an inner peripheral side wall of the cup body 1.
  • the liner 4 is formed by pressing a circular paperboard, after pressing, the annular side wall 42 of the liner 4 forms a plurality of folds 43 protruding inwardly in a vertical direction, and the folds 43 are arranged in a circumferential direction.
  • An angle of the annular side wall 42 after bending is larger than an angle between a side wall of the cup body 1 and the cup bottom, and after putting the liner 4 into the cup body 1, the annular side wall 42 has a small amount of elasticity, so that the annular side wall 42 abuts against the inner peripheral side wall of the cup body 1.
