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.
Claims46
A nurser liner for containment within a predetermined volume of space, said nurser liner comprising:
- an elongated liner body having an open end;
- a rim being located at said open end, said rim having a radial portion and an axial portion, said axial portion having an inner circumference;
- and
- a single step being located adjacent said rim, said step having a first surface virtually perpendicular to said radial portion of said rim, and having a second surface basically parallel to said radial portion of said rim but located a predetermined distance from said rim, said second surface having an outer circumference,
- wherein said outer circumference of said second surface of said step is greater than said inner circumference of said rim, and
- wherein said step precludes a second nurser liner which has been stacked therein from contacting said rim thereby facilitating removal of the second nurser liner from said liner body.
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 liner body having an open end and a closed end, wherein each liner body forms a taper from said open end to said closed end by an angle up to about 2.0 degrees;
- a first liner of said plurality of nurser liners having a flexible rim located at said open end, said rim having a radial portion and an axial portion, said rim having a bead positioned on a top surface of said rim;
- and
- means, positioned adjacent and below said rim, for spacing said first liner from an adjacent, second liner of said plurality of nurser liners;
- said second liner having a rim located at said open end;
- wherein when said first liner is positioned in said second liner, said means prevents said rim of said first liner from contacting said rim of said second liner to facilitate denesting of said first liner from said second liner.
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 and an open end;
- a first liner of said plurality of nurser liners having a flexible rim located at said open end, said rim having a radial portion and an axial portion, said rim having a bead positioned on a top surface of said rim;
- and
- means, positioned adjacent and below said rim, for spacing said first liner from an adjacent, second liner of said plurality of nurser liners;
- wherein when said first liner is positioned in said second liner, said spacing means prevents said rim of said first liner from contacting said rim of said second liner, and wherein said first liner is separated from said second liner by a predetermined separation length, wherein said predetermined separation length is about 0.030 inches to about 0.500 inches.
A nurser liner for containment of a liquid therein and adapted to be secured in a nurser holder having a nipple removably secured thereto, said nurser liner comprising:
- an elongated liner body having an open end and a closed end located opposite said open end;
- a flexible rim located at said open end, wherein said liner body tapers inward from said open end to said closed end by an angle up to about 2.0 degrees;
- a bead extending upward from a top portion of said rim to prevent the liquid from leaking from between said nurser liner and the nipple when said nurser liner is secured in the nurser holder and to prevent rotation of said nurser liner;
- and
- means, positioned adjacent and below said rim, for spacing said rim from a rim of an adjacent second nurser liner that has said nurser liner positioned therein.
A nurser liner for containment of a liquid therein and adapted to be secured in a nurser holder having a nipple removably secured thereto, said nurser liner comprising:
- an elongated liner body having an open end and a closed end located opposite said open end, said liner body having a height from about 5.25 inches to about 6.50 inches;
- a rim, located at said open end, being more resilient than said liner body, said rim having a radial portion and an axial portion, wherein said liner body tapers inward from said open end to said closed end by an angle up to about 2.0 degrees;
- a bead extending upward from a top portion of said rim to prevent the liquid from leaking from between said nurser liner and the nipple when said nurser liner is secured in the nurser holder and to prevent rotation of said nurser liner;
- and
- means, positioned adjacent and below said rim, for spacing said rim from a rim of an adjacent second nurser liner that has said nurser liner positioned therein, wherein said spacing means precludes the rim of said second nurser liner from contacting said rim of said nurser liner thereby facilitating denesting of said nurser liner from the second nurser liner.
