DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a sanitary napkin consisting of an absorbent body and a casing surrounding it.
BACKGROUND OF THE INVENTION
Leakage arising from sanitary napkins or pantiliners are in most cases caused by improper positioning of the napkin already on its application in a panty, or by the absorbent body being at least partially displaced from its initial position.
Sanitary napkins having flaps projecting laterally from the center of the absorbent body, which primarily serve to protect the crotch portion of the panty from discoloration, are previously known. Although preventing to a certain degree lateral displacement of the sanitary napkin in the crotch portion, such flaps do not support the absorbent body at its ends.
OBJECT OF THE INVENTION
The object of the invention is to improve a napkin of this type so as to reduce the risk of leakage associated with sanitary napkins.
BRIEF SUMMARY OF THE INVENTION
This object is achieved with a sanitary napkin according to the invention. By the flaps being located at the front edge of the napkin they will be more readily accessible, enabling them in this manner to be secured to the outside of the panty after putting it on. Also, the inventive napkin is more easily fitted into its proper position since adjustment can be done at the end instead of at the center of the napkin.
In a preferred embodiment of the invention, the side flaps extend in the longitudinal direction of the absorbent body from the end of the napkin intended to be placed in front, and up to at least the center of the absorbent body. Furthermore, the side flaps are made tapering from said front end of the napkin.
The inventive design of the flaps will enable the napkin to be folded into packages prior to as well as subsequent to usage, which is a great advantage from the user's aspect.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other features and advantages will be disclosed in more detail in the following description of an embodiment of the inventive sanitary napkin with reference to the accompanying drawings, of which
FIG. 1 shows a sanitary napkin according to the invention with the side intended for attachment inside a panty facing the viewer;
FIG. 2 shows an alternative embodiment of the sanitary napkin according to FIG. 1; and
FIGS. 3a-3d show the various steps of folding the sanitary napkin according to Claim 1 into a package.
DETAILED DESCRIPTION OF THE INVENTION
The sanitary napkin illustrated by the figures comprises an absorbent body 1 encapsulated in a casing which is composed of two interconnected surface layers 2, 3. The surface layer 2, which is a liquid impermeable layer facing the panty during use of the napkin and therefore constitutes the so-called outside of the casing, is secured at spaced points to the panty as will be explained later on, whereas the surface layer 3 is a liquid permeable layer facing the wearer's body during use and constituting therefor the so-called inside of the casing.
As can be seen from the figures, at least one end of the casing has lateral extensions forming side flaps 4, 5. In FIG. 1 the side flaps extend from one end of the napkin to the other end thereof and are made tapering from the upper end as seen in the figure, which end is to be forwardly placed within a panty for which reason it is referred to in the following as the front end of the napkin. The casing is provided on its outside with adhesive layers 6, 7 located at the forward ends of the side flaps, as well as an adhesive layer 8 disposed at the rearward end on the outside of the casing, said adhesive layers serving as attachment means for the napkin inside the panty.
Application of the sanitary napkin takes place in the following manner. The napkin is placed inside a partially pulled down panty which is then pulled up. If the napkin is properly positioned, which is easily ascertained when the panty is put on, the laterally projecting flaps 4, 5 are folded around the edge of the panty and the adhesive layers 6, 7 are affixed to the outsid
