Abstract
There is provided a nurser liner that facilitates stacking and nesting of the liner while maximizing liner capacity. In particular, it permits a plurality of the liners to be contained within a container having limited internal space while allowing the liners to de-nest properly and individually from the container. The nurser liner includes a rim that is located at one end of the liner and a step that is located a predetermined distance from the rim. In addition, the outer walls of the liner are slightly tapered inward from the rim. The step and the tapered outer walls insure uniform spacings between nested liners for easy dispensing, optimal spacing between liners and maximum liner capacity.
Claims7
A stack of nurser liners for containment within a predetermined volume, said stack comprising:
- a plurality of nurser liners, each liner having an elongated liner body with a central axis, each of said liner body having an open end and an opposite end, said liner body tapering toward the central axis from said open end to said opposite end by an angle no greater than about 2.0 degrees;
- a first liner of said plurality of nurser liners having a rim located at said open end, said rim having a radial portion and an axial portion;
- and
- a second liner of said plurality of nurser liners having means for separating said second liner from said first liner, said separation means having a first surface that is located virtually parallel to the central axis of said liner body and a second surface that is located virtually radial to said liner body,
- wherein said second surface of said separation means of said second liner abuts said radial portion of said rim of said first liner so that said first liner is separated from said second liner by a predetermined separation length.
A stack of nurser liners for containment within a predetermined volume, said stack comprising:
- a plurality of nurser liners, each having an elongated liner body with a central axis and an open end;
- a first liner of said plurality of nurser liners having a rim being located at said open end, said rim having a radial portion and an axial portion;
- and
- a second liner of said plurality of nurser liners having a single step, said step having a first surface that is located virtually parallel to the central axis of said liner body, a second surface that is located virtually radial to said liner body but located a predetermined distance from said open end, and said step further including a third surface and a fourth surface
- wherein said second surface of said step of said second liner abuts said radial portion of said rim of said first liner so that said first liner is separated from said second liner by said predetermined distance.
