• the wringer can be attached to the container so that any removal of the applicator through the opening will cause the applicator to pass through the wringer as well.
• the shape of the wringer including the tubular shape of the wringer sleeve, constrains the way the applicator passes through the wringer. Therefore, the shape of the wringer inherently defines a direction of insertion and withdrawal of the applicator through the wringer, let alone taking into account conventional shapes and sizes of applicators. Since the direction of insertion and the direction of withdrawal are generally confused, one or the other will be used interchangeably below, unless explicitly stated otherwise or is apparent from the context.
• the direction of withdrawal may correspond substantially to the axis of the wringer, or even the axis of the wringer sleeve, the geometry of the wringer and the conventional configuration of an applicator allowing at most a limited movement around of this axis.

• bevel lip we will also speak of “bevel lip” hereinafter.
• the flexibility of the wiping sleeve and the lip provided at a bevel interact to improve the wiping of the applicator: thanks to the bevelled shape of the lip, during the passage of the applicator in the wiper sleeve along the direction of withdrawal, the distal portion of the lip, in response to the deformation of the wiper sleeve assembly, scrapes the tip of the applicator and remove the 'possible drop of product which would otherwise have remained on the applicator.
• the wringing sleeve can be deformed to best adapt to the shape of the applicator to be wrung out.
• the wiper sleeve may possibly be deformed by curving inside itself, which allows it to closely match the shape of the applicator and to reject the excess product inside the container; we sometimes talk about the "sock effect" to designate this particular type of deformation.
• the attachment part has less flexibility than the wringer sleeve, the attachment of the wringer to the container can be effectively maintained when the applicator passes through the wringer.

• wringing (more particularly the length of the aforementioned frustoconical part, excluding an attachment portion of the wringing sleeve with the fixing part) in the direction of withdrawal is greater than the largest inner radius of the sleeve spinning transversely to said direction. Thanks to these characteristics, by deforming, the wringing sleeve can reach to the most central parts of the applicator, which increases the efficiency of the wringing.
