DIAPER AND INTEGRAL EVERSION CONTAINER
Abstract
A damp proof easily disposable diaper is provided comprising a
pad of absorbent sheet material carried in superimposed relation by
a bag of water resistant sheet material forming a damp resistant
backing for the pad. After use, the bag may be manually everted
through an opening thereof to enclose the pad therein. To
facilitate the eversion, an end portion of the pad attached to the
bag only adjacent the opening may be released therefrom and folded
over the remaining portion of the pad thereby covering soiled
surfaces thereof.

Claims
Having thus described my invention what I claim as new and desire
to secure by Letters Patent of the United States is:
1. A damp resistant diaper ensemble in the configuration of a flat
elongated rectangle, said ensemble having a means for manual
eversion of a bag to enclose a used damp diaper comprising a diaper
having on one half length, at least one adhesive means across the
width thereof, a water resistant bag of sheet material of a size
substantially coextensive of the diaper and having an opening in a
first end portion and attached on the outside surface adjacent its
second end portion to said diaper adhesive means, said outside
surface of said bag adjacent its opening and the diaper second half
being joined by an adhesive tack means to define a disengageable
attachment means between the bag and diaper whereby said bag
opening defines a hand insertion means so said diaper second half
portion may be readily detached from the bag, folded over the
remaining first portion to cover the soiled surfaces, and be
enclosed in the bag by said manual eversion thereof.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to improvements in diapers and more
particularly to improvements in diapers adapted for disposal after
use.
2. Description of the Prior Art
The disposal of used diapers has generally been a disagreeable
task. Retaining diapers for washing or for disposal as trash is apt
to create problems of sanitation and the generation of odors. An
existing diaper construction is at least partly disposable in
toilets, but this manner of disposal is not always completely
satisfactory as it requires careful handling in rinsing matter off
a water proof backing sheet and the separate disposal of the
backing sheet.
Related problems of disposing of used catamenial devices as
discussed in U.S. Pat. No. 3,024,788 have been approached by a
construction including a bag attached to a flexible extension from
the pad, the bag being usable to enclose the pad. However this
construction is not adapted to provide a suitable diaper.
SUMMARY OF THE INVENTION
It is accordingly an object of the present invention to provide an
improved diaper in which the construction provides enhanced
capability for pleasant, convenient and sanitary disposition of the
diaper after use.
Another object of the present invention is to provide an improved
diaper incorporating means for the convenient and sanitary
enclosure of the pad of the diaper after use, which means also
serves to provide a damp resistant backing for the pad of the
diaper.
To these ends and in accordance with the present invention, there
is provided an improved diaper comprising a pad of absorbent sheet
material and a bag of water resistant sheet material carrying the
pad in superimposed relation therewith, the bag forming a damp
resistant backing for the pad and having an opening therein to
admit a hand for manual eversion of the bag to enclose the pad
after use.
To facilitate the manual operation of eversion of the bag to bring
the pad inside it, an end portion of the pad preferably
constituting approximately about one half of its length, is secured
to the bag only by attachment thereto adjacent the opening so that
after use of the diaper in the operation of everting the bag, the
end portion may be detached from the bag and folded over the
remaining portion of the pad, thereby enclosing soiled surfaced and
making the diaper more pleasant to handle.
Other features and advantages of the invention will best be
understood from the following description taken in connection with
the appended drawings.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a plan view, partly broken away, of a diaper embodying
the present invention;
FIG. 2 is a side elevation of the diaper shown in FIG. 1; FIG. 3 is
a side elevation of the diaper shown in FIG. 1 illustrating a stage
in the operation of manual eversion; and FIG. 4 is a view,
generally in side elevation, of another stage of the operation of
manual eversion in the disposal of the diaper of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 & 2 of the drawing, the diaper of the
present invention comprises an absorbent pad 10 formed of a
conventionally suitable material and a bag 12 of water resistant
sheet material such as plastic film carrying the pad 10 in
superimposed relation therewith. Preferably, and as shown, each of
the pad 10 and the bag 12 has a generally rectangular
configuration. The rectangular form of the pad 10 is elongated to
provide the desired fit to an infant while the bag 12, as shown,
may be generally co-extensive with the pad.
The bag 12 has an opening 14 (FIG. 2) at one end thereof to receive
a hand (FIG. 4) in the operation of everting the bag. To make this
operation more convenient and pleasant, an end portion 16 of the
bag 10 is secured to the bag 12 only by attachment thereto adjacent
the opening 14 so that the portion 16 may be released from the bag
and folded over the remaining portion 18 of the pad thereby
covering soiled surfac of the pad and making the eversion operation
more pleasant. Preferably the attachment of the pad portion 16 to
the bag 12 takes the form of adhesive tacks 20 at the corners of
the bag adjacent the opening 14, using any suitable cement such as
a contact cement. Thus any tearing of the bag which might occur
upon release of the portion 16 therefrom is confined to the area of
the bag adjacent the opening 14 and will not interfere with the
subsequent enclosure of the pad since the major portion of the bag
12 remains intact. Suitably each of the portions 16 and 18
constitute approximately one half of the length of the pad 10. The
portion 18 is bonded to the bag 12 to maintain its superimposed
disposition therewith during the manipulation of the diaper.
Suitably, and as shown, the attachment of the portion 18 may be
accomplished by a plurality of adhesive bonds 24 extending across
the pad 10.
In operation, after a used diaper has been removed from an infant,
the end portion 16 of the pad 10 which is tacked to the bag 12 is
released from the bag and folded over the remaining portion 18.
After folding of the pad to the disposition illustrated in FIG. 3,
a hand may be inserted through the opening 14 of the bag to grasp
the folded pad through the material of the bag as shown in FIG. 4
and the operation completed by withdrawing the pad through the
opening 14 and tying off the everted bag in conventional
manner.
