Description

BACKGROUND OF THE INVENTION [0001] The present disclosure relates to a pantyhose comprising a thighbelt attached to the pantyhose as well as a method of mounting a lacework on the pantyhose.

As shown in FIG. 1, a pantyhose is generally composed of two portions 10 of generally tubular shape, knitted separately from one another. The two parts 10 each comprise a lower portion 12 for forming the legs of the pantyhose as well as the pants and an upper portion 12 for forming the belt. The two parts 10 are then slit 16 at their upper ends and assembled to one another by several seams to form a panty and belt.

This traditional construction leads to a belt that has three main disadvantages: - visually, it cuts the silhouette on a horizontal plane which is little female; - It tightens and shears the belly and hips often rolling on itself which can cause bulges and discomfort for the person who wears the tights; - the seams at the waist are thick and can cause red marks on the stomach, which in addition to theirdisgrasieux effect, can also cause discomfort.

In the following description, the terms "before", "back", "upper", "lower", "up", "down" refer to the position or orientation of an element or of a compound, that position or orientation being defined relative to a person standing on a horizontal surface. The terms "inside" will also be used to designate the face intended to come into contact with the person and "outside" to designate the face intended to be worn when the person is wearing the tights.

OBJECT AND SUMMARY OF THE INVENTION [0005] The present disclosure seeks to remedy at least in part these disadvantages.

For this purpose, the present disclosure relates to a tights comprisinga lower end and an upper end, a culotteecomantant a front end and a rear end and a belt, an upper portion of the pants having a cutout such qu'hautor of the The rear end of the panty is greater than a height of the front end of the panty, the height being measured with respect to the lower end and in a plane of symmetry of the pantyhose, the belt being attached to the upper part of the panty so that a line of assembly of the belt on the breeches is present.

Due to the difference in height of the pants, the belt is lower on the front of the tights than on the back. This form provides comfort when the tights are worn by a person. Indeed, the belt goes down to the front end of the pants and is placed comfortably on the person.

Moreover, this belt being attached to the upper ends of the pants, the material used for the belt may be different denature of the material of the pants. For example, it is possible to use materials that can not be knitted or that are difficult to knit.

It is understood that the pants and the belt are two different parts which are assembled to one another. Indeed, the belt is not knitted with the pantyhose.

The cutting can be obtained by cutting a portion of laculotte, for example using a wireless serger, a cutting wheel, scissors, a band saw, a jigsaw, or a cutting laser.

The cut can be obtained by a particular ductile knitting, so that once finished, the pants has a cut, that is to say, an upper edge such as a height of the rear end of laculotte is greater than a height of the front end of the pants.

The belt may be attached to the upper part of laculotte by ultrasonic welding or stitching.

The ultrasonic welding makes it possible to form a line of solid assemblies and not having an excess thickness.

The seam allows to form a solid assembly line.

The adhesive may comprise a reinforcing strip bonded to the assembly line.

This reinforcing strip reinforces the assembly of lace on the pants. It also makes it possible to hide the assembly line. Thus, this reinforcing tape can also increase the comfort of the person wearing the tights.

This reinforcing strip may be a film of polymeric material deposited and bonded to the assembly line, for example a film of material comprising silicone or polyurethane.

This reinforcing strip allows a better support of the glue when it is worn reducing the risk that the sticky moves relative to the person who wears when this person moves.

The reinforcing strip may have an elongation in the direction of the length of the reinforcing strip greater than an elongation under load in the direction of the width of the reinforcing strip.

Thus, the reinforcing strip may accompany the ducking deformation and belt, especially when the person puts or removes the adhesive.

The elongation under load is measured according to standard NF EN14704-1.

The belt may be formed of a strip and comprise two cut ends.

The band intended to form the belt has a general form of ribbon, that is to say a form of quadrilateral whose two opposite sides are parallel and form the upper and lower edges of the belt. Cutted ends are the sides of the quadrilateral linking these two opposite sides.

The belt may also be formed of a band forming a ring.

At least one cut end may be attached to a lower edge of the strip, forming an overlap area of the strip on a front portion of the panty.

At least one cut end may be attached to an upper edge of the strip.

Each cut end can be attached to a lower edge of the strip, forming an overlap zone of the diamond-shaped strip on a front portion of the panty.

This increases the fastening force of the belt. Eneffet, each end being attached, it reduces the risks that the belt can partially detach or open.

It will be noted that the square is a particular example of the rhombus.

The two cut ends can be attached to one another.

The cut ends can for example betreattached by gluing, by ultrasonic welding, by sewing.

Once cut or ends cut (s) attached (s), the band can form an angle at the front end of the pants, which can be greater than or equal to 80 ° (degree), preferably greater than or equal to 90 °, still more preferably greater than or equal to 100 ° and may be less than or equal to 160 °, preferably less than or equal to 150 °, still more preferably less than or equal to 140 °.
