With these embodiments
1
A,
1
B of gown as illustrated, it is unnecessary for the wearer to develop the first and second rear bodies
6
a
,
6
b
in the circumferential direction so as to be spaced from each other when the wearer inserts the arms into the sleeves
4
. This is for the reason that the backside of the basic body
2
has previously been opened in the circumferential direction.
Furthermore, both the gown
1
A and the gown
1
B are free from an anxiety that the outer surfaces of the front body
5
as well as the first and second rear bodies
6
a
,
6
b
might come in contact with clothes and skin of the wearer when the gown is worn. This is for the reason that, as will be apparent from
FIGS. 1 and 7
, the first and second rear bodies
6
a
,
6
b
are in advance folded back onto the front body
5
, i.e., the respective outer surfaces of these rear bodies
6
a
,
6
b
face the outer surface of the front body
5
and the respective inner surfaces of them face outward of the gown
1
A,
1
B before the gown
1
A,
1
B is actually worn.
For these embodiments
1
A,
1
B of the gown, hydrophobic fibrous nonwoven fabric made of thermoplastic synthetic resin fiber, two-layered hydrophobic fibrous nonwoven fabric or a composite sheet comprising a flexible, air-pervious but liquid-impervious thermoplastic synthetic resin film sandwiched by hydrophobic fibrous nonwoven fabric may be used.
Nonwoven fabric may be selected from a group including products obtained by spun lace-, needle punch-, melt blown-, thermal bond-, spun bond- and chemical bond-process. It is also possible to use a composite nonwoven fabric comprising a melt blown nonwoven fabric having a high water-resistant property sandwiched by a spun bond nonwoven fabric having high strength and flexibility.
Component fiber of the nonwoven fabric may be selected from a group consisting of polyolefine-, polyester-, polyamide-based fibers and core-sheath-type or side-by-side conjugated fiber of polyethylene/polypropylene or polyethylene/polyester. It is also possible for the nonwoven fabric to be made mixed with cellulose-based fiber such as fluff pulp, rayon or acetate fiber.
As stock material for the tape member
15
, a flexible plastic sheet made of polyethylene, polypropylene, polyethylene terephthalate, polyester.
Bonding of the front body
5
to the first and second rear bodies
6
a
,
6
b
as well as attachment of the tape member
15
, the hook members
17
,
19
and the loop members
18
,
20
may be performed using hot melt adhesive or heat welding technique such as heat-sealing or ultrasonic sealing.
Depending on the wearers' body sizes, the gown
1
A or
1
B is provided in various sizes such as S, M, L, LL and, after packaged in sterilizing bag, subjected to a sterilizing process using gaseous organic chemicals or electron beam or radiation.
With the disposable surgical gown according to this invention, the tape member retains the gown in the state such that the first and second rear bodies have been folded back onto the front body (the backside of the basic body
2
has been opened in the circumferential direction) before the gown is actually worn. Therefore, it is unnecessary for the wearer to develop the first and second rear bodies in the circumferential direction so as to be spaced from each other when the gown is actually worn. Handling of the gown is correspondingly facilitated.
Furthermore, the gown is free from an anxiety that the outer surfaces of the front body as well as the first and second rear bodies might come in contact with cloths and skin of the wearer and be contaminated with various germs when the gown is worn. This is for the reason that the first and second rear bodies are folded back onto the front body
5
in advance prior to actual use of the gown.
