Definitions

  • the present invention relates to paper cups that can be stacked to save storage and transportation costs.
  • a conventional paper cup 1 comprises a cup body 2 and a bottom 3, which form a holding space.
  • a manufacturing process for the cup includes:
  • the cup body 2 has an annular side wall 21 with an outwards folded cup edge 22 of height "h" provided on the ring edge (cup rim).
  • the cup bottom 3 has an annular side wall 31 that is mated with the annular side wall 21 of the cup body 2 at the end of the side wall 21 that is remote from the cup edge 22.
  • the annular side walls 21, 31 where the cup body 2 is mated with the cup bottom 3 have a height of "H", generally, "H" is greater than "h".
  • An object of the invention is to provide a paper cup that can reduce the stacking gap and transportation cost or at least to provide an alternative to known papers cups.
  • the invention may provide a paper cup structure with increased strength that avoids softening and provides a robust and anti-skidding arrangement.
  • the invention may provide a paper cup structure with good sealing and leak-proofing properties.
  • a paper cup according to the invention comprises a cup body and a bottom; the cup body is provided with an annular side wall, and an outward folded arced cup edge is set on the ring edge at one end; the cup bottom is provided with an annular side wall and bonded with the inner side of the annular side wall of the cup body far away from the cup edge; so the cup body and bottom form a holding space; particularly, an inflexed edge is formed at the annular side walls where the cup body is abutted with the cup bottom, thus reducing the height of the annular side wall for mating of the cup body and bottom.
  • the inflexed edge of the paper cup may be of a two-layer inflexed edge structure formed by repetitively bending the annular side wall of the cup body, or a three-layer inflexed edge structure formed by extending the cup bottom's annular side wall to the cup body's annular side wall.
  • FIGS. 3 and 5 depict an embodiment of a paper cup 1.
  • the paper cup 1 generally comprises a cup body 2 and a cup bottom 3.
  • the cup body 2 has an annular side wall 21 and an outwardly folded arced cup edge 22 at one end.
  • the cup bottom 3 has an annular side wall 31 that is mated with the annular side wall 21 of cup body 2 at the end opposite the end at which the the cup edge 22 is disposed.
  • the cup body 2 and cup bottom 3 define a holding space for liquids and the like.
  • An inflexed edge 4 is formed at the annular side walls 21, 31 where the cup body 2 is abuts the cup bottom 3. This can reduce the height of the annular side wall 31 for the mating of the cup body and bottom. This can reduce the height of the annular side wall 31 for mating of the cup body 2 and bottom 3 to allow the height H ( FIG. 5 ) to be equal to or less than the height h of the cup edge 22.
  • the paper cup 1 can be manufactured by the following process charted in FIG. 4 :
  • FIG. 5 is a side view of the paper cup 1 of FIG. 3 formed by combining the cup body 2 and bottom 3 by the above-specified process.
  • the cup body 2 has an annular side wall 21 and an outwardly folded cup edge 22 of height "h" provided at the cup rim.
  • the cup bottom 3 has an annular side wall 31 mated with the annular side wall 21 at the end of the side wall 21 that is remote from the cup edge 22.
  • the cup body 2 and cup bottom 3 form a holding space.
  • An inflexed edge 4 is formed at the annular side walls 21, 31 where the cup body 2 abuts the cup bottom 3. This allows the height "H" between the cup bottom 3 and inflexed edge 4 to be equal to or less than the height "h" of the cup edge 22.
  • the inflexed edge 4 is formed by bending and extending the annular side wall 21 of the cup body 2 ( FIG. 5 ) or by bending the annular side walls 21, 31 of the cup body 2 and bottom 3 ( FIG. 7 ).
  • the inflexed edge 4 of the bottom of each cup can abut the inner side of the bottom 3 of the paper cup below, and the cup edges 22 of stacked cup bodies can be kept in contact, or near contact, so as to at least reduce the gap.
  • FIGS. 6 and 8 show stacked paper cups1 according to the invention. It is clearly shown that when a large number of paper cups 1 are stacked, the inflexed edge 4 of the bottom of each paper cup 1 can be close to or abut the inner side of the bottom 3 of the paper cup 1 below. Furthermore, the cup edges 22 of stacked cups can be kept in contact, or near contact, to at least reduce the gap between them. This can save on the required storage space and transportation cost for the stack.
  • the inflexed edge 4 of the paper cups 1 illustrated by FIGS. 3 and 5 to 9 allows for a reduction in the height of the cup bottom. This addresses the shortcomings of the paper cup illustrated by FIGS. 1 and 2 that has a space between the cup edges 22 of the paper cups that results in larger storage and transportation costs.
  • the paper cups 1 illustrated by FIGS. 3 and 5 to 9 reduce or eliminate the gap between the cups in a stack of paper cups, thus reducing the storage space required by about 30%. Alternatively, a greater number of the cups can be stored in a given storage space. In either case this can reduce transportation costs.
  • FIG. 9 shows cross section views of the cup bottoms of the paper cups of FIGS. 5 and 7 .
  • the inflexed edge 4 of the paper cup 1 shown on the left is of a two-layer bonded structure with leak-proof effect that does not include the annular side wall 31 of the cup bottom 3. This structure can be applied to small-capacity (under 9oz) paper cups.
  • the inflexed edge 4 shown on the right has a three-layer bond structure that comprises the extended and bent annular side wall 31 of the cup bottom 3 in combination with two-layers of the cup body 2 with better leak-proof effect. This structure can be applied to large-capacity (above 12or) paper cups.
