Wiper insert
First Claim
1. A wiper insert for a container for the storage of a fluid, said wiper insert being formed of a cylindrical length of yieldable material around a central axis and comprising:
- a body portion possessing a body portion inner diameter and a body portion outer diameter;
a distal end portion at one end of said body portion; and
a proximal end portion at an opposite end of said body portion, said proximal end portion forming an annular flange about said central axis and comprising;
an inner surface having a first end with a first inner diameter equal to said body portion inner diameter at the junction of said inner surface with said body portion and having a second end with a second inner diameter exceeding said first inner diameter;
an outer surface having an outer diameter exceeding said body portion outer diameter; and
a lip disposed between said inner surface second inner diameter and said outer surface;
wherein;
said lip is in the form of a protruding structure extending upward from said inner surface to direct fluid wiped on said lip inward; and
said inner surface slopes inwardly from said lip at said second inner diameter to said body portion at said first inner diameter to direct liquid from said lip inward.

Abstract
A wiper for use in a container for liquids such as correction fluid consists of a cylindrical length of yieldable material within the neck of the container. The wiper may be formed as an insert which consists of a cylindrical body formed about a central axis and having an upper end in the form of an annular flange, with which to engage the container neck, and a lower end extending toward a reservoir within the container. From the body depend one or more cleaning elements angled toward the central axis, the ends of the elements extending beyond the lower end of the insert and defining a gap allowing for frictional passage of an applicator, and allowing removal of excess fluid from the applicator. The upper end terminates in a wiping lip upon which an applicator may be wiped to remove liquid before application. Excess liquid so removed flows through apertures provided between the cleaning elements.

14. An insert for a container having a reservoir for the storage of a fluid and a neck, the fluid being removed from the container and applied via an applicator, said insert having a central axis and fitting into and seating upon the neck of the container, said insert comprising:
-
an annular flange portion engaging and seating around the neck of the container and comprising an uppermost end having a first inner diameter and a lowermost end having a second inner diameter smaller than said first inner diameter, said flange portion inwardly sloping from said first inner diameter to said second inner diameter; and a wiping lip at said first inner diameter and protruding upward from said flange for removing excess fluid from the applicator and guiding the fluid away from the exterior of the container so that the fluid does not remain on said insert. - View Dependent Claims (15, 16)

17. A container for the storage of a fluid and adapted to be used with an applicator inserted through a container opening, said container comprising:
-
a reservoir portion for containing fluid; and a neck portion defining an opening to said reservoir portion, said opening being formed around a central axis, said neck portion including a wiper disposed annularly around said opening and central axis, wherein said wiper comprises; an upper opening portion defining said opening to the outside of said container and having a first inner diameter sloping inward and downward to a second inner diameter smaller than said first inner diameter; an annular wiping lip in the form of a protruding structure extending upward from and surrounding said upper opening portion at said first inner diameter of said upper portion, said wiping lip and said upper portion being shaped to direct excess fluid wiped onto said wiping lip into said reservoir so that fluid does not remain on said insert; and an inner portion disposed below the upper portion, said inner portion including an annular wall shaped for removing excess liquid from the applicator passed therethrough. - View Dependent Claims (18, 19, 20, 21)
