Abstract

A protective garment for use as overalls or trousers or as a pullover or jacket is made of a rectangular blank having two overlapping panels which are connected to each other along the two longitudinally extending marginal portions of the blank and, if necessary, along one transversely extending marginal portion. A first row of perforations is provided to form an elongated tongue starting at the one transversely extending marginal portion and extending midway between the longitudinally extending marginal portions toward but well short of the other transversely extending marginal portion. The perforations are surrounded by a welded or otherwise formed seam which converts the blank portions flanking the tongue into two tubes to constitute the leggins or the sleeves of a garment. The tongue is provided with one or more rows of perforations to form at least one strip which can be detached to be used as a sash or to form three strips, one to be used as a sash and the other two to be used to tie the leggins or sleeves to the legs or arms of the wearer. The blank has two weakened portions which are adjacent the other transversely extending marginal portion and can be destroyed to form two straps which are placed over the shoulders or are received in the crotch of the wearer.

Description

The invention relates to a protective suit made of two layers of sheet-like sheet material, in particular of film or non-woven material, which are connected to one another at the two longitudinal edges and at most one transverse edge, with a first parting line extending essentially from the transverse edge and with a seam, which, together with the longitudinal edges, delimits two tube-like sections.

Such a protective suit is known from EP-A-235 556. Protective suits of this type consist of foil or non-woven material, plastic foils in particular being used. The term “nonwoven material” encompasses all surface materials made from fiberized textile fibers, in particular plastic textile fibers, and spunbond materials. Form the hose-like sections of the protective suit Pants legs or sleeves. If the layers are connected to one another at the transverse edge from which the tube-like sections extend, the sleeves or trouser legs are closed. If such a protective suit is worn by a moving person, it can happen, especially in the case of the closed trouser legs, that the material expands, the trouser legs becoming longer, the gusset or step sliding down and finally the wearer of the protective suit in his mobility is impaired. In order to eliminate such a "rompers effect", the protective suit can be secured with a belt. However, a belt is an additional part that must be manufactured and provided.

From CH-A-540 019 an apron is known, on the lower transverse edge of which a separable strip of material is cut via weakening lines, which are also referred to below as perforation lines. Before using the apron, the material strip can be separated and used as a belt.

Protective suits of the type mentioned at the outset can be connected to one another at their end faces or transverse edges via perforation lines and wound up on a roll. If you also provide detachable strips of material on the end faces to be able to use them as a belt, there is a risk that not only the protective suit but also the material strip of the next protective suit will also be separated when a protective suit is torn off the roll. This means that you get a protective suit with two belts, but the next protective suit without a belt. In addition, the length of the belt is usually not sufficient, since it only corresponds to the circumference of the protective suit.

The invention has for its object to increase the wearing comfort in a protective suit with simple handling.

This object is achieved in a protective suit of the type mentioned at the outset in that a second parting line is provided which starts from the transverse edge and returns to it and, together with the transverse edge, delimits a web region which extends essentially in the longitudinal direction and contains the first parting line, whereby the second parting line is surrounded by the seam and the web area can be used as a belt or fastening tape.

The strip of material, which is provided for fastening purposes, thus extends in the longitudinal direction between the sleeves or trouser legs. There is usually a gap there anyway, from which the sheet material would otherwise have to be removed during production. According to the invention, the removal of this surface material is now dispensed with, leaving a strip of material that can be used to better attach the protective suit to the user. The length of the material strip is increased by the first parting line. In extreme cases, it can be almost twice the length of the trouser legs or sleeves. The web area has the same thickness as the rest of the protective suit and fits seamlessly into the protective suit. When spread out and not in use, the protective suit can be spread out flat without disturbing ups and downs. This is particularly helpful when packing a large number of protective suits in a stack or on a roll.

In a preferred embodiment, the second parting line forms a parting weld together with the seam. No material is wasted here. The entire web area between the seams is then available to provide a tape that can be used to fasten the protective suit.

The first parting line preferably starts from one end of the web area and ends in the web area. The rail area is thus in one piece. In this case it can preferably be used as a belt. Depending on where the first parting line ends, the belt length is almost twice the length of the sleeves or trouser legs.

In a further preferred embodiment, the second parting line has two interruptions which are essentially opposite one another in the transverse direction. The web area therefore remains connected to the sleeves or trouser legs at these two interruptions. In this case, the first parting line completely penetrates the web area. This creates fastening straps that are firmly cut on the trouser legs or sleeves. After putting on the suit, the user can fix the trouser legs on the leg or the sleeves on the arm by looping and knotting the straps formed by the web area around the leg or arm.

It is preferred that the interruptions are arranged in the third of the tube-like sections adjacent to the transverse edge. This creates a longer area and a shorter area of the web section, ie a longer and a shorter band. Since the longer band hangs down, it will protrude over the trouser leg or sleeve and, if one is not knotted, will drag it on the floor. The user is therefore encouraged to tie the two straps on each leg or arm and to secure the suit.

A third parting line is advantageously provided, which runs essentially in the longitudinal direction in the web area and divides the web area into three one-part sections. The third parting line runs essentially parallel to the first parting line, i.e. it passes through the railway area twice. In this embodiment, not only does a section arise which can be used as a belt, but two pairs of bands remain on the hose-like sections, i.e. the trouser legs or sleeves, with which the trouser legs or sleeves can be fastened to the legs or arms .

To facilitate handling, the parting lines are preferably designed as perforation lines. In this case you get a one-piece suit that is easy to handle. There are no disruptive material sections that protrude and make handling more difficult. Only after the perforation has been opened is the parting line opened and the web area divided into the corresponding elements, i.e. belts or fastening tapes. The separation is easily possible due to the perforation or weakening line.

At least one of the parting lines advantageously has the shape of a wavy line. The sections that can later be used as belts or fastening tapes accordingly also have a wavy line at least at a boundary line. This improves the elasticity of the belt or straps. In addition, such a wavy line protects the device used to manufacture the protective suit, since an iron producing the wavy line does not always fall on the same place on a moving device that transports the sheet material.

Advantageously, a cutout is provided at the inner end of the seam which interrupts the seam. This cutout is intended for the passage of the head when the protective suit is to be worn as a jacket or sweater. In this case, the two tubular sections form the sleeves. The parting line forming the cutout is preferably also formed by a perforation or weakening line. If the perforation is not separated, the protective suit designed as a jacket can also be used as trousers. This allows a more flexible use.

It is also preferred that two lateral incisions are provided near the other transverse edge, whereby a bib part, two holes for arms or legs and two cut-off supports are formed. The carriers result without the material cutouts having to be made. The dimensions of the incisions result in an adaptation to the size of the person. Such a protective suit can easily be used as trousers. The straps are slipped over the shoulder of the person. If such a protective suit is used as a jacket or sweater, the legs can be passed through the openings, the wearers holding the protective suit in place at the crotch and preventing it from sliding upwards.

A hose advantageously forms the two layers of the surface material. With a hose of this type, the two longitudinal edges of the two layers are already connected to one another. During production, only the joints and seams have to be made, if necessary by means of separation welding.

In a further preferred embodiment, the two layers are formed by sheet material folded onto one another. In this case, the surface material can be in the form of a half tube, for example. Here, the two layers are already connected to one another on one side. During production, a connection between the two layers and the seams and parting lines only have to be made on the other longitudinal edge.

In a further embodiment, however, it is also preferred that the surface material is folded essentially at a quarter and at three quarters of the transverse extent, the longitudinal edges of the surface material touching or slightly overlapping along a center line, and that the first parting line and the seam are open runs on both sides of the center line. This creates closed legs or sleeves, while the bib section can remain open. However, it can also be closed, for example by gluing or welding the two flat material sections.

The surface material is advantageously folded inwards on the longitudinal edges. This results in a "pocket fold". The usable inner volume of the protective suit is increased without the outer dimensions of the protective suit having to be significantly increased when not in use.

At least one of the parting lines is preferably designed as a parting weld. The two layers of the sheet material are thereby attached to each other.

Fig. 1 shows a ready-to-use, one-piece disposable protective suit 1 in the form of bib shorts. The protective suit 1 is formed from a piece of hose 2. It has two trouser legs 3, 4, which are delimited by the longitudinal edges 5, 6 and a seam 7a, 7b. The seam 7a, 7b not only connects the two layers of the hose section 2, but also separates a web area 8 from the hose section 2. In the web area 8, a first parting line 10 is provided which extends from the lower transverse edge of the hose section 2, i.e. starts from one end of the web area and ends in web area 8. The seam 7a, 7b is designed as a separating weld seam, i.e. a second parting line 9a, 9b is provided immediately next to the seam 7a, 7b and is surrounded by the seam 7a, 7b. Furthermore, a third parting line 11a, 11b is provided, which divides the web area into three one-piece sections 12, 13, 14. All parting lines 9a, 9b, 10, 11a, 11b can be designed as parting welds, i.e. when separating, the two layers of the tube piece 2 can be welded together. The first parting line 9a, 9b has two interruptions 15, 16 which are essentially opposite in the transverse direction and at which the material areas 12, 13 are connected to the trouser legs 3, 4. The breaks 15, 16 are in the lower third, i.e. arranged in the third of the trouser legs 3, 4, which is adjacent to the transverse edge of the hose body 2.

All parting lines 9a, 9b, 10, 11a, 11b are designed as perforation lines or weakening lines. The sections 12, 13, 14 are still loosely connected to the trouser legs 3, 4, but can be separated by hand without difficulty. If the parting lines 9a, 9b, 10, 11a, 11b are now separated, the section 12 creates two bands 17, 18 with which the trouser leg 3 can be attached to the leg. For this purpose, the longer band 18 is wrapped around the leg and knotted with the shorter ribbon 17. The arrangement of the interruptions 15, 16 ensures on the one hand that the trouser leg can be fastened approximately at the level of the lower leg, but on the other hand the user is also reminded of the fastening of the straps 17, 18. The upper band 18 is so long that it would protrude beyond the lower transverse edge without attachment and thus drag on the floor. This is perceived as uncomfortable by users. He will therefore voluntarily use the straps 17, 18 to attach the trouser leg 3 to the leg.

The section 14, on the other hand, forms a belt which has approximately twice the length of the trouser legs 3, 4. This belt can be wrapped around the waist, and due to its length there is sufficient attachment.

The first and third parting lines 10, 11a, 11b have the shape of a wavy line. This improves wearing comfort because there are no sharp edges that could cut into the skin of the user. In addition, the elasticity of the straps or the belt is increased slightly. The risk of the tapes tearing when put on is reduced.

A transverse seam 19 is provided at the lower end in the region of the lower transverse edge of the tube piece 2. The trouser legs 3, 4 are therefore closed at the lower end. The opposite end of the hose section 2 is open in any case. Incisions 20, 21 running in the transverse direction are provided parallel to this open end of the tube piece 2. Surrender this way there are two cut supports 22, 23 which can be turned up and connect on both sides of a bib part 24. There is an opening for the head between the straps, armholes are created outside the straps. Folds 25, 26 are provided on the two longitudinal edges of the hose section 2, on which the hose section is folded inwards. This results in an increase in the internal volume when using the protective suit, without the external dimensions of the unused protective suit being significantly increased.

Before use, the protective suit 1 is in the form of a flat structure, i.e. apart from the folds 25, 26, it consists only of two superimposed layers of a surface material, for example a film or a nonwoven, i.e. a web of fibrous textile or textile plastic fibers or of spun-bonded material. The belt-forming section 14 and the fastening straps sections 12, 13 are arranged in the surface of the protective suit 1. They extend essentially in the longitudinal direction, i.e. they cannot be cut off accidentally if two protective suits are connected in the transverse direction.

Fig. 3 shows a second embodiment of a protective suit, in which the same parts are provided with reference numerals increased by 100. The web area 108 only has the first parting line 110, as a result of which a belt 27 shown in dashed lines can be formed, and is enclosed by the second parting line by the parting weld seam 107a, 107b.

FIG. 4 shows a third embodiment, in which elements which correspond to those of FIG. 1 are provided with reference numerals increased by 200. In this embodiment, only the sections 212, 213 are provided, which serve as fastening straps for the trouser legs 203, 204. The sections 212, 213 are connected to the trouser legs 203, 204 via the interruptions 215, 216 of the separating weld seam 207a, 207b. The trouser legs 203, 204 are closed by the seam 219.

Fig. 5 shows a fourth embodiment in which the protective suit is designed as a protective suit top or pullover. Parts which correspond to those of FIG. 1 are provided with reference numerals increased by 300. The tubular sections 303, 304 here form sleeves which are delimited by the longitudinal edges of the tubular piece 302 and by the separating weld seams 307a, 307b. The separating weld seams 307a, 307b are interrupted by interruptions 315, 316, whereby the sections 312, 313 are integrally connected to the sleeves 303, 304. The two sections 312, 313 are separated from one another by the first parting line 310. At the inner end of the second parting line, a cutout 28 is provided which interrupts the seam 307a, 307b. The head can be guided through this cutout when the protective suit is slipped over the upper body. The cutout is formed by a perforation line, so that no material has to be removed during production. The hands and arms are passed through sleeves 303, 304. The legs can be guided through the incisions 322, 323, whereby a secure fit of the protective suit upper part 301 can be achieved. The sleeves can be attached to the arms with the aid of sections 312, 313, which are arranged in one piece on the sleeves 303, 304 by passing one end of sections 312, 313 around the arm and then tying it to the other end of sections 312, 313. If the user does not remove the material from the cutout 28, ie does not open the perforation line, this protective suit designed as a jacket or pullover can also be used as trousers.

FIG. 6 shows a fifth embodiment, in which parts which correspond to those of FIG. 1 are provided with reference numerals increased by 400. The two layers of the surface material are no longer available as a hose. Rather, they were created by folding a single-layer surface material 29. The sheet material is folded essentially at a quarter and at three quarters of the transverse extent, the longitudinal edges 30, 31 touching or slightly overlapping along a center line 32. If side folds are provided, the words "a quarter" or "three quarters" refer to the connecting line between the sections of the sheet material which are to be assigned to the upper and lower layers. The second parting line and the seam, which are jointly formed by the parting weld seam 407a, 407b, run on both sides of the center line 32. This forms the two trouser legs 403, 404. The center line 32 can form the first parting line 410 at the same time if the lower layer of the sheet material is also cut through. This in turn creates two sections 412, 413 which are connected to the trouser legs 403, 404 via the interruptions 415, 416 of the separating weld seam 407a, 407b. The two longitudinal edges 30, 31 of the single-layer material 29 can be connected to one another, for example by welding or gluing, but they can also be left open. This creates a protective suit with an open bib.
