BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to panty briefs formed by a flat knitted, substantially rectangular front piece and back piece, which are made separately, and which by interknitting are connected along marginal edge zones in the sides of the panty briefs for forming side seams, and along a part of the bottom of the panty briefs for forming a crotch region separating two non-connected parts of the marginal edge zones at the bottom of the panty briefs for forming leg openings, the panty briefs being made with elastic threads, which generally extend from one side to the other of the front and back pieces for providing a circumferentially elastic contraction in the panty briefs.
THE PRIOR ART
It is known to make panty briefs by knitting with different forms in order to obtain the best possible fit without a need for after-fashioning of the panty briefs. Even though several proposals have been made, the panty briefs for fixation of a napkin will normally require a circumferential elasticity so that an elasticity occurs at the leg-bands formed at the marginal edge zone at the bottom of the panty briefs; however, the elasticity at the leg-bands may be irritating for the user due to a local compressive press.
WO 91/19845 describes panty briefs with front and back pieces connected along other parts of marginal edge zones. Leg openings are provided opposite each other at a lower non-connected part of the marginal edge zones. In order to obtain a crotch region with some elasticity, some embodiments may have a zone having a looser knitting. However, the knitting is always provided as closed stitches and this is a drawback because it is necessary to control the knitting process very accurately and because the knitting must be different depending on which part of the panty briefs is being knitted.
Panty briefs according to the present invention may be considered as a further development of panty briefs which are described in the U.S. Pat. No. 3,656,324, the content of which is hereby incorporated by reference. Thus materials, knitting types, stitch size, embodiments, etc., which are described in this United States Patent may also be used when making the panty briefs according to the present invention.
It is the object of the present invention to remedy the drawbacks of the known panty briefs, especially for fixation of napkins, by providing panty briefs of the above-mentioned type, which may be made by machines and in endless lengths without a need for after-fashioning and which are provided with leg openings, which do not cause a local compressive press on a user.
SUMMARY OF THE INVENTION
According to the present invention this is obtained by panty briefs, characterized in that, in the finished panty briefs, only part of the stitches being formed in the front and back pieces of the panty briefs in a marginal edge zone at the bottom of the panty briefs when knitting the panty briefs are closed.
Finished panty briefs in which only part of the stitches in the marginal edge zone are closed will appear with a loose structure. Thus, the remaining part of the stitches, which during or after the making of the panty briefs are opened, will give rise to a surplus of yarn between the remaining stitches. In practice, this means that the stitches formed in the finished panty briefs will be substantially larger, thus resulting in the looser structure. Stated in a popular way, if only half of the stitches in the finished panty briefs are closed, it is possible to make the stitches twice the size of those of traditional flat knitted panty briefs in which all of the stitches are closed.
As the marginal edge zone, which is located in the vicinity of the leg openings at the bottom of the panty briefs has a looser structure, the finished panty briefs acquire a very great width in the leg openings, which will not give rise to the local compressive press which traditional leg-bands may cause.
According to the invention panty briefs will not solely be suitable as normal panty briefs, but will also be especial
