Problems solved by technology

[0020] Furthermore, the above examples provide no indication as to the press configuration required to achieve tampons with complex longitudinal or radial shapes
[0021] Despite all the shaped tampons proposed in the prior art, there is still a need to address the main consumer concerns: wearing comfort and leakage avoidance

Embodiment Construction

[0058] As used in the specification and claims:

[0059] The term "formed longitudinal profile" and its variants relate to the configuration of the edges of the object considered along the longitudinal axis of the press;

[0060] "Formed" means that the edge of the object is not straight throughout its length; it may be curved, possibly several times. In other words, the profile profile may comprise concave or convex curves individually or in succession in one or more curves. It may also include one or more straight sections associated with one or more curved sections;

[0061] The term "tampon blank" and variations thereof relate to uncompressed tampon material;

[0062] The term "wadding" and variations thereof relate to a pad or compact of absorbent material, such as fibers, designed to absorb body fluids. "Tampon wadding" or "absorbent tampon wadding" refers to compressed absorbent material after compression of tampon blanks in a press;

[0063] The term "groove" and v...

Abstract

A press for shaping an absorbent tampon blank into a shaped tampon wadding, the press comprising: a central cavity arranged and configured to receive an absorbent tampon blank having a front portion and a rear portion. A main longitudinal axis of the press passes intermediate the central cavity, and a plurality of penetrating dies are arranged radially about the main longitudinal axis. Each penetrating die has a pressing surface on at least one segment of its side facing the central cavity. The press includes at least one cam to actuate the plurality of penetrating dies. Further, the plurality of penetrating dies includes at least one penetrating die having a pressing face with a first shaped longitudinal profile and at least one penetrating die having a pressing face with a second shaped longitudinal profile. A shaped tampon and uses of such shaped tampons are also disclosed.

Description

technical field [0001] The present invention relates to intravaginal tampons, such as absorbent menstrual tampons for feminine hygiene. In particular, it relates to a press for producing such tampons having a through-die with a shaped pressing surface; a tampon made therefrom; and a finger-shaped tampon having a molding shape. Background technique [0002] Intravaginal tampons have been used for decades. There are two types of tampons on the market, digital tampons and tampons that require an applicator. Typically, digital tampons are formed by radially compressing a blank with a set of jaws, while applicator tampons are formed by molding the blank. Both types of tampons have a generally cylindrical shape, and both have advantages and disadvantages. [0003] Digital tampons can be manually inserted without an applicator. They have a clean smooth surface; however, the rigidity required for finger-like insertion from the column of compression created by the press jaws wit...
