Description
The present invention relates to a mop head of the disposable type,
that is one that may be thrown away after limited number of
uses.
It is known that conventional dust mop head made of cloth rapidly
become charged with grime and, in order to preserve their
usefulness, they must be removed from the handle and washed from
time to time because the dust and light dirt have accumulated and
have become ingrained in the cloth and can no longer be shaken
off.
Now, washing of such dust mop heads is obviously highly
inconvenient because, due to their heavy dirt content they cannot
be washed together with other items. It is therefore necessary
either to wash them by hand or to dedicate a full washing machine
cycle to them alone.
It is therefore a main object of the present invention to provide a
disposable mop head which can be manufactured at such a low cost
that it can be thrown away after several uses. Another object is in
the provision of a mop head capable of collecting dust and light
dirt as efficiently as a cloth mop head.
In accordance with the above objects, the mop head of the invention
comprises a support having a rectangular backing face over which a
plurality of elongated flexible sheets, made of dust and light dirt
collecting material, are secured by one of their longitudinal edges
in such a way as to project from the backing face. The sheets are
distributed over substantially all of the backing face and are
obtained from one single band of collecting material folded in
accordion fashion to create successive paired plies defining the
sheets, the successive paired plies being connected to the backing
face by folds that define the secured edges. Further, the sheets
are formed with a plurality of slits running from their other
longitudinal edges toward the secured edges but terminating short
of the said secured edges to thereby create a mass of flexible
mopping strips. Finally, the secured edges of plies located along
two sides of the rectangular face are disposed closer than those at
the center of the face whereby to create, along the sides, denser
areas of mopping strips.
In a preferred embodiment of the invention, the mopping strips of
the denser areas are longer than those between the denser
areas.
In accordance with the invention, the dust and light dirt
collecting material is a natural or synthetic fibrous material.
Furthermore, it may be especially treated, in known manner, to
attract and retain dust and light dirt. Natural fibrous material
such as paper, sisal, hemp, cotton, wool, flax, jute, crepe paper
or similar fibrous materials can be used. Also, by using an
impervious material, the mop head may serve for washing floors.
It is believed that a better understanding of the invention will be
afforded by the description that follows of various embodiments of
the invention, having reference to the appended drawings
wherein:
FIG. 1 is a perspective view of a partially completed mop head made
according to a first embodiment of the invention;
FIG. 2 is an elevation view showing the mop head of FIG. 1 in a
position of use;
FIG. 3 is an elevational view of a detail of the mop head,
according to the invention, shown on an enlarged scale;
FIG. 4 is a prospective view showing part of a mopping sheet being
secured to the support, and
FIG. 5 is an elevational view of a mop head according to a second
embodiment of the invention.
Referring now to FIGS. 1 to 4, the mop head of this embodiment is
formed of a flat support 10 having a backing face. The support is
preferably flexible and may be a sheet of paper or of a fabric
material. In known manner, this support will eventually be
connected to a mop frame provided with a handle. The method of
mounting the mop head on the frame not being a feature of the
present invention, no further details will be added, for the sake
of simplicity.
To this backing face 10 are secured a plurality of elongated
flexible sheets 14 made of dust and light dirt collecting material,
sheets 14 being secured to the backing face of the support 10 by
one of its longitudinal edges while the remaining part of the
sheets project away from the backing face. They are distributed
over substantially all of the support 10. As will be noted from
FIGS. 1 and 4, particularly, sheets 14 are formed with a plurality
of slits 15 running from the other longitudinal edges and
terminating at the secured edges 16 thereby defining a mass of
flexible mopping strips 12, that is, the slits 15 may either run
right up to or terminate short of the securing edges 16; the latter
form being shown in FIG. 4.
In the particular form of embodiment illustrated in FIGS. 1, 2, 3,
and 4 the strip-defining sheets 14 are obtained from several bands
made of dust and light dirt collecting material, each band being
centrally folded upon itself with the central folds defining the
aforesaid securing edges 16. The said edges 16 may be secured to
the backing face of the support 10 in any known manner such as by
being glued, stitched, stapled or sewed thereon.
As shown in FIG. 1, the support 10 is preferably rectangular and
the sheets 14 are disposed with their secured edges 16 extending
along lines parallel to one long side of the rectangular face 10,
each sheet having a length equal to the length of the support 10.
The sheets 14 may also come in short lengths disposed side by side
in lines parallel to the long side of the rectangular support
10.
It is however found more practical that each sheet 14 have a length
that extends the full length of the support 10.
Preferably, and for greater efficiency in collecting dust and light
dirt, the sheets 14 that define the flexible mopping strips 12 are
disposed closer to one another along the two long sides of the
rectangular backing face 10 then at the centre, thus creating
denser areas of mopping strips. If the sheets come in short lengths
it will be possible to provide such denser areas all around the
four sides of the face 10.
In order to improve the dust collecting feature of the mop head,
the strips 12 of the denser areas may be made longer than those at
the centre of the backing face 10, as shown in FIG. 2.
In the embodiment illustrated in FIG. 5, the strip-defining sheets
20 are obtained from one single band folded in accordion fashion to
create paired plies 22 connected by folds 24 defining edges that
are secured on the backing face of the support 18. The paired plies
22 are slit in the same manner as the sheets 14 of FIGS. 1 and
4.
In this embodiment, as in the first one, the secured edges 24 of
the paired plies 22 located along the two long sides of the
rectangular support 18 may be disposed closer than those at the
centre whereby to create, along these long sides, denser areas of
mopping strips. Furthermore, the latter strips may also be longer
than those located between the denser areas.
Under this embodiment of FIG. 5, it is obvious that the same result
may be obtained by using a plurality of juxtaposed sheets,
(disposed side-by-side) each being folded accordion fashion.
As previously mentioned, the dust and light dirt collecting
material from which the flexible mopping strips 12 and 22 are made
is a fibrous material, either natural or synthetic. Among suitable
natural fibrous materials are: paper, sisal, hemp, cotton, wool,
flax, jute, crepe paper. Obviously, synthetic fibrous material can
also be used as well as material capable of generating static
electricity to attract dust. Also, by using non-dissolving
impervious material the mop head may be used for washing
floors.
