[0135] FIG. 8 is a front view of trouser-type protective equipment for a clean room or sanitised environment according to the invention.

[0136] In the figures, identical or similar elements bear the same references.

[0137] FIG. 1 shows protective equipment 1 for a clean room or sanitised environment according to the invention and more particularly an overall 7 for a clean room or sanitised environment comprising an outer face 2 intended to be in contact with the surrounding environment and an inner face 3 arranged to be in contact with a user or operator.

[0138] The overall 7 comprises a first 9 and a second 10 leg section, each of which comprises a flank and two longitudinal edges on either side of the flank of the leg section, each of which is also provided with mutual closure means which are arranged to form the substantially tubular leg section when the mutual closure means of each longitudinal edge are engaged together. In addition, the mutually engaged closure means of the first leg section face the mutually engaged closure means of the second leg section, and the mutual closure means each preferably extends at least from a knee area to a crotch area (not shown) and more preferably from a calf or ankle area to a crotch area (not shown).

[0139] Although not shown in the figures described, the closure means of the first leg section and the closure means of the second leg section together form a continuous closure of the opening of the crotch. The closure means are selected from a zip, hook-and-loop fastener means, press studs, a flap or other equivalent or similar means.

[0140] The overall 7 also comprises a first sleeve 12, a second sleeve 13 and a body portion 14. The first sleeve 12 is connected to the body portion 14 via a linked end 12a, the second sleeve 13 is also connected to the body portion 14 via a linked end 13a. The first leg section 9 and the second leg section 10 are connected to the body portion 14 via a linked end 9a and 10a respectively. Finally, the body portion 14 of the overall 7 includes a head passage section 15.

[0141] In the embodiment as shown in FIG. 1, the overall 7 comprises a hood provided with an opening for the eyes above or below which a mask or goggles for example can be placed.

[0142] The overall 7 according to the present invention and as shown in FIG. 1 comprises a pouch 4 which is connected to the inner face 3 of the overall 7 via fastening means 8. The fastening means 8 are located on the inner face of the pouch 4 and preferably opposite the opening 5 of the pouch 4. This advantageously allows the inner face of the pouch 4 to be attached to the inner face 3 of the body portion 14 of the overall 7.

[0143] Thus, in the folded and packaged position, the inner face 3 of the overall 7 is connected to the inner face of the pouch 4 so that only the outer face of the pouch 4 is in contact with the surrounding environment such as shown in FIG. 4. When the operator is to put on the overall 7, before doing so they will open the closure means 6 of the opening 5 of the pouch 4, remove the overall 7 from the pouch 4 using the gripping means 16. After this step has been carried out, when the overall 7 is taken out of the pouch 4, a reversal, an inversion of the faces of the pouch 4 will take place.

[0144] Particularly advantageously, first the outer face of the pouch 4, which was exposed to the surrounding environment, will become the inner face of the pouch 4. Second, the pouch 4, being connected to the inner face 3 of the overall 7, will therefore end up inside the overall 7 when the latter is worn by the operator.

[0145] Consequently, the pouch 4 of the protective equipment 1 and more particularly of the overall 7 according to the present invention makes it possible to achieve double isolation of possible contaminants. Isolation is first achieved by the inversion of the outer face of the pouch 4 which ends up inside the pouch 4, with the contaminants therefore being contained in the pouch 4. Containment is also achieved by the containment of the pouch 4 inside the overall 7.

[0146] In the embodiment of FIG. 1, the first sleeve 12 comprises self-tightening means 17 at a free end, opposite the linked end 12a, in the form of an elastic fabric wrist cuff. The second sleeve 13 also comprises at the free end, opposite the linked end 13a, self-tightening means 17, in the form of an elastic fabric wrist cuff. The elastic fabric wrist cuffs as shown in FIG. 1 can also be replaced by a press stud flap, or hook-and-loop fastener means, or other conventional tightening means.

[0147] In addition, according to the embodiment of the protective equipment 1 and more particularly of the overall 7 of FIG. 1, the overall 7 has, in the unfolded position, wherein the outer face 2 of the overall 7 is in contact with the surrounding environment and the inner face 3 is arranged to be in contact with an operator. The first inner face of the pouch 4 is against the inner face 3 of the overall and the second inner face of the pouch 4 is arranged to be in contact with or oriented towards an operator. The closure means 6 of the opening 5 of the pouch 4 are preferably in the open position. It is obviously possible for the closure means 6 to be in the closed position, in particular to isolate the outer faces of the pouch 4, inside the pouch 4 when the overall 7 is in the unfolded position.

[0148] The overall 7 according to the present invention comprises at least one gripping means 16 in contact with the inner face 3 in the body portion 14, preferably located laterally. In the variant shown in FIG. 2a, the overall 7 according to the invention comprises two gripping means 16 in contact with the inner face 3 in the body portion 14, located laterally, on either side of the opening 11. In the other variant shown in FIG. 2b, the overall 7 according to the invention comprises a gripping means 16 in contact with the inner face 3 in the body portion 14.

[0149] FIGS. 2A and 2B show two embodiments of the overall 7 according to the present invention in the partially folded position. The inner face 3 of the first leg section 9 and the second leg section 10 are exposed to the outside, to the surrounding environment. The outer face 2 of the first leg section 9 and the second leg section 10 are exposed to the outer face 2 of the body portion 14. This particular arrangement according to the present invention forms an opening 19 which is itself arranged to provide access to the inside of the body portion 14 and preferably to the inside of the trunk portion of the overall 7.

[0150] In this way, the at least one gripping means 16 is exposed to the operator.

[0151] In the embodiment of FIG. 2A, the overall 7 according to the invention comprises two gripping means 16 exposed to the operator.

[0152] In the embodiment of FIG. 2B, the overall 7 according to the invention comprises a gripping means 16 exposed to the operator.

[0153] In yet another embodiment not shown, the gripping means 16 of the overall 7 according to the present invention can be parts of material of the inner face 3 of the overall 7 and therefore exposed to the operator. Furthermore, the different parts of material of the inner face 3 of the overall 7 or of the protective equipment 1 for a clean room or sanitised environment can be of different colours, textures or patterns to allow the operator to identify them as being the gripping means 16.

[0154] Indeed, the gripping means 16 according to FIGS. 2A and 2B are present on the inner face 3 of the overall 7 and the act of partially inverting the leg sections on the body section makes it possible to expose them to the outside and therefore to the operator.

[0155] It is therefore easy to understand from the overall 7 according to the present invention that the steps of the folding method must be followed in order to maintain the sterility of the overall 7, in particular following removal of the overall 7 by the operator and its cleaning, decontamination and subsequent repackaging.

[0156] Particularly advantageously, the overall 7 according to the present invention comprising the pouch 4 makes it possible to dispense with single-use packaging and for it to be cleaned and repackaged directly in its protective pouch 4, which can itself be cleaned, sterilised and reused.

[0157] During this folding step, the operator folds down the outer face of a first 9 and a second 10 leg section by passing an open crotch section over an outer face of a body portion 14 while keeping the at least one gripping means 16 exposed.

[0158] The second step of the folding method is as shown in FIG. 3. In this step, the first leg section 9 is folded longitudinally onto itself and the second leg section 10 is also folded longitudinally onto itself while leaving the two gripping means (16) exposed to the operator. In addition, the last step of folding the overall according to the invention is shown using arrows in FIG. 3. Indeed, the overall 7 according to the invention thus folded will then be folded transversely onto itself in two or three portions or even more if necessary, depending on the size of the overall. The overall 7 thus folded is then packaged in the pouch 4 accessible in the body portion 14 of the overall 7. Once folded and packaged, the pouch 4 containing the overall 7 as shown in FIG. 4 can for example be sterilised, for example, in an autoclave.

[0159] Before putting on an overall 7 according to the invention, the user opens the closure means 6 of the opening 5 of the pouch 4, grips the first gripping means 16 with a first hand and the second gripping means 17 with the second hand and removes the overall 7.

[0160] In this way, an overall 7 in the partially folded position is obtained as shown in FIG. 2A. The overall 7 is positioned so that the body portion 14 is accessible via the opening of the crotch 19 of the overall, via the waist section. The operator then puts, after having released the second gripping means 16 their second arm, into a second sleeve 13 and, after having released the first gripping means 16, they put their first arm into the first sleeve 12. They then pass their head through an opening in the body portion 14 via the waist section and then through the head passage section 15 until their head reaches the hood.

[0161] They then invert the leg sections 9, 10 so that the outer face of the first leg section 9 and the second leg section 10 are exposed to the outside and so that the inner face of the first leg section 9 and the second leg section 10 are exposed to the legs of the operator. Then, the operator places their foot in the foot passage section which comprises the pre-engaged zip and closes said opening 19 in order to completely isolate their body from the external environment.

[0162] FIG. 5 shows clogs as protective equipment for a clean room or sanitised environment according to the present invention. The clogs as shown comprise a series of press studs 8 where a first portion of the male stud is located on the clogs and a second portion of the female stud is located on the pouch 4, the reverse obviously being possible. Thus the clogs can be attached to the pouch 4, and positioned inside the pouch 4 so that during removal, the clogs will be removed and the pouch 4 will be inverted on itself as explained above so as to isolate contaminants inside the pouch 4.

[0163] FIG. 6 shows protective boots as protective equipment for a clean room or sanitised environment according to the present invention. The protective boots as shown comprise a series of press studs 8 where a first portion of the male stud is located on the boots and a second portion of the female stud is located on the pouch 4, the reverse obviously being possible. Thus the protective boots can be attached to the pouch 4 and positioned inside the pouch 4, so that during removal, the protective boots will be removed and the pouch 4 will be inverted on itself as explained above so as to isolate contaminants inside the pouch 4.

[0164] FIG. 7 shows gloves, overshoes, a hairnet and a hood as protective equipment for a clean room or sanitised environment according to the present invention. The protective equipment as shown may comprise a means for being fastened 8 to the pouch 4, such as a press stud. Thus it can be attached to the pouch 4, and placed inside the pouch 4 so that during removal, the protective equipment will be removed and the pouch 4 will be inverted on itself as explained above so as to isolate contaminants inside the pouch 4.

[0165] FIG. 8 shows trousers according to the present invention comprising a first 9 leg section and a second 10 leg section. The trousers as shown comprise an inner face 3 and an outer face 2, and also comprise the pouch 4 according to the present invention.

[0166] Thus the operator can put on the trousers and the pouch 4 as described above, and being located inside the trousers makes it possible to isolate the contaminants, first in the pouch 4 and second in the inner portion of the trousers which is isolated from the surrounding environment.

[0167] It is understood that the present invention is in no way limited to the embodiments described above and that many modifications can be made thereto without departing from the scope of the attached claims.
