Claims
Having thus fully disclosed my invention, what I claim is:
1. A dispenser for dispensing a moist flexible sheet material
containing a liquid for medical, cleansing or similar purposes
comprising a container for holding a supply of said sheet material
and fully enclosing said supply, said container consists of at
least two parts adapted to be secured to each other and to be at
least partially separated from each other to permit said supply of
sheet material to be renewed when required, said parts comprising a
cylindrical casing having covers on its opposite ends, at least one
of said covers being removably connected to said casing, means for
locking said removable cover in a predetermined position to said
casing, and a pair of parallel raillike projections secured to the
inner side of each of said covers and extending in the same
direction on both covers, said supply consisting of a roll of said
material, and a core upon which said roll is wound, said core
having ends projecting from said roll and inserted between and
slidable along the associated pairs of projections, said casing
having a longitudinal wall and a dispensing passage in said wall
through which said material may be withdrawn from said supply in a
moist condition to the outside, means for restricting said passage
to a width substantially equal to the thickness of said material so
that the liquid will be substantially prevented from evaporating
from said container, and cutting means on the outer side of said
container for cutting off a moist section of said material.
2. A dispenser as defined in claim 1, in which said dispensing
passage comprises a longitudinal slot in the wall of said casing
and extending parallel to the axis of said casing, said slot being
located in an upper part of said casing when said dispenser is
mounted in an operative position and having a length equal to the
width of said material.
Description
The present invention relates to a device for dispensing a moist
flexible fibrous sheet material which has been treated with a
suitable liquid for medical, sanitary or similar purposes. More
particularly, the device according to the invention is intended for
anal-hygienic purposes, for example, for use in toilets.
There are various kinds of dispensers already known which are
intended, for example, for use in kitchens, toilets, or hospitals
and comprise containers for receiving wrapping paper, toilet or
toweling paper or even surgical bandages or dressings. None of
these containers is, however, suitable for receiving a liquid or a
moist roll which is already saturated with a liquid, since it is
not closed airtight toward the outside and the liquid would either
evaporate from the container itself or from the moist roll within
the container. Furthermore, these containers are usually also not
provided with supporting means which insure that the respective
container will be held in such a position that, if a moist roll is
inserted therein, the liquid with which this roll is saturated will
not drain out of it so that the roll will eventually dry out.
It is an object of the present invention to provide a dispenser
which eliminates the above-mentioned disadvantages and comprises a
container which is especially suitable for receiving a moist roll
or long folded strip of any desired fibrous sheet material and is
designed so as to prevent as much as possible the evaporation of
the liquid with which the roll or folded strip is saturated or
which might be held in the container for moistening the sheet
material before it is withdrawn from the container.
For attaining this object, the present invention provides that the
container is adapted to receive a roll or a long folded strip of a
suitable sheet material which is moistened or saturated with a
chemical, pharmaceutical, or medical liquid substance or that the
container is adapted to hold a certain quantity of such a liquid
substance and the sheet material passes from a dry roll or folded
strip within the container through this substance before it is
withdrawn from the container, and that the container which is
otherwise tightly closed is provided with a continuous longitudinal
slot through which the desired length of the moist sheet material
may be withdrawn from the container and which is closed toward the
outside as air-tight and liquid-tight as possible either by the
sheet material itself or by additional sealing means.
In order to render the container according to the invention as
inexpensive and economical as possible, it is advisable to make it
of a single piece of material, for example, of plastic, which
encloses the roll or folded strip of sheet material and may be
thrown away when empty. Such containers may be made of a very
simple shape and be mass-produced at a very low cost. They may be
useful especially if, when made, they already contain the roll or
folded strip of sheet material in the moistened or saturated
condition. The container may, however, also consist of several
parts so as to permit it to be refilled whenever necessary and also
to permit different sheet materials and/or different liquids to be
inserted therein.
Another feature of the invention consists in providing a supporting
device for the container which permits this container to be secured
in the proper operative position. This supporting device may
consist, for example, of a pair of feet which are secured to the
opposite ends of the container and extend transverse to the axis of
the latter and have a length substantially equal to the width of
the container. These feet permit the container to be rested or
mounted in a fixed position in which any excess of the liquid with
which the roll or folded strip of sheet material is saturated will
always accumulate in a predetermined part of the container or in
which the liquid which is filled into the container for saturating
the sheet material before it is withdrawn through the dispensing
slot will always be located in the proper part of the container for
such a saturation.
For producing the container at a low cost, it is advisable to make
it in the form of a cylindrical casing and to provide its opposite
ends either with a fixed cover and a removable cover or with
removable covers on both ends. These removable covers are
preferably secured to the casing in a predetermined position by
bayonet or snap locks or the like and they are further provided
with guide bars projecting for a short distance toward the inside
of the casing for guiding the ends of a core on which the roll of
sheet material is wound. These guide bars on the two covers may
extend either vertically or diagonally depending upon the
particular operating position in which the container is to be
mounted. If the guide bars extend diagonally to the container and
at an angle to its supporting device, the container may be mounted
in either of two operative positions extending at an angle of
90.degree. to each other. The container may thus be mounted either
on a horizontal surface, for example, on a table, or on a vertical
surface, for example, on a wall. Since the guide bars extend
diagonally in either of these positions, the core of the roll the
projecting ends of which are slidable between these guide bars will
always tend to slide downwardly within the container so that at
least the outer layers of the material on the roll which are next
to be withdrawn from the container will always be immersed in the
liquid which is kept in the lowest part of the container. In any
operative position of the container, its dispensing slot should
extend substantially parallel to the axis of the container and thus
in a horizontal direction and be preferably located within the
upper part of the container, and the length of this slot should
substantially correspond to the width of the sheet material. The
width of the slot should be so narrow that it will be closed
substantially air-tight and liquid-tight by the sheet material
passing therethrough so that the liquid which is held in the
container will not evaporate to the outside.
Another feature of the invention consists in providing the
container on its outer side with a cutting device which extends
along the dispensing slot at one side thereof and may consist of a
straight or serrated blade. This cutting device may, however, also
be similar to the blade of scissors and be pivotable relative to
the slot about an axis near one end thereof. Intermediate the
dispensing slot and the cutting device, the outside of the
container should further be provided with a row of gripping pins
for holding the end of the sheet in a fixed position which is to be
torn or cut off. These gripping pins further prevent the short end
of the sheet material which projects to the outside of the slot
after each cutting operation from slipping back through the slot
toward the inside of the container. It is, however, also possible
to provide the container with a straight or serrated cutting edge
along the dispensing slot and with a holding plate which may, for
example, be pivotable about the container and extend parallel to
the slot and the cutting edge. This holding plate may be pressed
downwardly, for example, with the thumb of one hand, so as to press
the end of the sheet material projecting through the slot against
the cylindrical surface of the container adjacent to the slot so
that a moist sheet or strip of any desired length may then be
easily cut off.
According to another feature of the invention it is advisable to
provide the container directly adjacent to the dispensing slot with
additional sealing lips, preferably of an elastic plastic, which
engage upon the opposite sides of the sheet material and thus seal
the container tightly toward the outside. When employing such
elastic sealing lips on a container which is adapted to be
refilled, it is also possible to make the dispensing slot of a
greater width so as to permit sheet materials of different
thicknesses to be employed. These materials may be of any suitable
type and consist, for example, of paper, gauze or fibrous fleece
materials of a very inexpensive kind which, even when wet, have a
good tensile strength.
The liquid with which the roll or folded strip of sheet material is
saturated or into which the dry sheet material is immersed in the
container may contain medicinal substances, for example, monovalent
or polyvalent alcohols such as, for example, ethanol, glycerin, or
sorbite, or antibacterial substances, for example, hexachlorophene,
tensides or tweenes. The liquid may in addition contain substances
with a cooling effect, for example, menthol or a hamamelis
solution, or odorous substances, for example, perfume oils, or
curing substances, for example, parabenes. Although the moist sheet
material may be employed for any other desired purpose, it is
primarily intended for anal-hygienic purposes.
The features and advantages of the present invention will become
more clearly apparent from the following detailed description
thereof which is to be read with reference to the accompanying
drawings, in which

its cutting device.
FIGS. 1 and 2, illustrate a dispenser according to the invention
which comprises a tubular container 1 which is closed at one end
and adapted to receive a roll 4 of a fibrous sheet material which
is saturated with a liquid containing chemical and/or
pharmaceutical, medical or other ingredients. A sheet 2 of this
material is to be unwound from the roll 4 and withdrawn to the
outside through a narrow longitudinal slot 3 in the container wall.
This slot 3 is designed so as to be closed sufficiently airtight by
the sheet 2 so that the liquid with which the roll 4 is saturated
or which is filled into the container 1 will be prevented from
evaporating. The container 1 may either consist of a single piece
of an inexpensive material, for example, plastic, which may be
thrown away after the roll 4 of saturated sheet material has been
consumed or it may be designed for being refilled. For cutting off
a sheet 2 of the desired length, the container is provided above
the slot 3 with a cutting edge 5. This cutting edge 5 may, however,
also be provided underneath the slot 3 which may in some cases
facilitate the cutting operation. FIGS. 1 and 2 also illustrate the
supporting device 6 for the container 1 which consists of a flat
board or plate 7 which is secured to the container 1, for example,
by screws, and is provided with a pair of holes 8 in its upper part
for suspending the dispenser on hooks on a wall. As shown in FIG.
2, the container is further provided on its side opposite to that
containing the slot 3 with a flangelike projection 9 into which the
screws for securing the plate 7 to the container may be screwed.
This projection 9 holds the container 1 at a certain distance from
the plate 7 so that the cover 10 of the container may be easily
fitted over or into the open end of the latter and will then close
the container airtight and liquid-tight. In this particular
embodiment of the invention, the cover 10 is additionally locked to
the container 1 by means of a snap lock 11 which may be easily
released. FIGS. 1 and 2 also indicate parallel guide bars 21 which
project from the inner sides of the cover and bottom of the
container 1 and are adapted to guide the opposite ends of the core
22 on which the roll of sheet material is wound.
FIGS. 3 and 4 illustrate a dispenser of a slightly different
construction. The container 12 of this dispenser is provided with
four feet 13 which are secured to the container near the opposite
ends thereof and permit the container either to be used while
mounted on a table or other horizontal surface in a position as
shown in FIG. 3, or while being hooked into eyes 14 on a board or
plate 15 which is secured to a wall, as shown in FIG. 4. The
longitudinal slot 16 in the container 12 through which a sheet may
be withdrawn is located in either of these operating positions of
the container 12 at an upper side of the latter.
FIG. 5 illustrates a dispenser according to another modification of
the invention. It comprises a container 17 which may be very easily
produced and consists of a cylindrical casing 18 the opposite ends
of which are closed by covers 19. This casing 18 may be made, for
example, of a transparent plastic so that the proper unwinding of
the sheet material from the roll 20 and the amount thereof
remaining on the roll at the inside of the container 17 may be
observed from the outside. The covers 19 may be secured to the
casing 18, for example, by means of bayonet locks, not shown, and
each of them is provided on its inner side with a pair of parallel
guide bars 21 for guiding the projecting ends of the core 22 on
which the roll 20 of sheet material is wound. The feet 23 by means
of which the container may be supported on a table or the like may
be cast either integral with the casing 18 or with the covers 19.
The upper side of casing 18 is provided with a dispensing slot 24
which extends parallel to the axis of the casing and has a length
equal to the width of the sheet material on the roll 20. For
tearing off a piece of the sheet material which has been withdrawn
through the dispensing slot 24, a serrated cutting edge 25 is
provided along this slot while for gripping the end of the sheet
material which projects from the slot 24 so as to prevent it from
slipping back into the container 17 a row of gripping pins are
provided on and project from the outer surface of the casing 18
between the slot 24 and the cutting edge 25.
In place of these gripping pins 26, it is, however, also possible
to provide a pivotable bar or strip along the dispensing slot 24
which by suitable spring means may clamp the end of the sheet
material while being torn off against the surface of casing 18.
A further modification of the dispenser according to the invention
is illustrated in FIG. 6. It comprises a container 28 for a roll 27
of a sheet material 33. This container 28 is adapted to be refilled
with a liquid and with a dry roll of a sheet material and is
therefore provided with a pivotable cover 29. On or adjacent to its
opposite end walls the container 28 is provided with slotted
transverse bars 30 into which the opposite ends of the core or pin
31 carrying the dry roll 27 may be inserted. This roll 27 is
pressed downwardly by a spring 32 which also exerts such a friction
upon the roll that it will not continue to rotate and will
therefore not be excessively unwound when the desired length of the
sheet material 33 is being withdrawn from the dispensing slot 37.
From the roll 27 the sheet material passes downwardly over a roller
35 and through a quantity of treating liquid 34 in the bottom of
the container 28 and then upwardly toward two wiping rollers 36 and
between the latter to and through the dispensing slot 37 which is
sealed toward the outside by two elastic sealing lips 38 which
engage upon the upper and lower sides of the sheet 33. When the
desired length of this sheet is withdrawn from the dispensing slot
37, it may be torn off on the cutting edge 39. The container 28 may
be secured in a simple manner by means of hooks 40 and eyes 41 on a
wall 42. This embodiment of the invention has the advantage that
the roll 27 of sheet material may be inserted in a dry condition
into the slots in the supporting bars 30 of the container and that
any desirable liquid 34 may be poured into the container 28 to
saturate the sheet material freshly before it is dispensed from the
container by being pulled through the slot 37. Due to the provision
of the sealing lips 38, the dispensing slot 37 may also be made of
a greater width so as to permit sheet materials of different
thicknesses to be employed.
The liquid for saturating the sheet material preferably contains
medically effective substances, for example, monovalent or
polyvalent alcohols such as, for example, ethanol, glycerine,
sorbite, antibacterial substances such as hexachlorophene and
tensides such as tweens or the like. The liquid may additionally
contain substances with a cooling effect, odorous substances such
as perfume oils, antiseptics or the like. All of these substances
may be employed in an aqueous solution or emulsion or be applied in
the saturating liquid in any other form.
In place of any of the containers as illustrated in FIGS. 1 to 6,
it is also possible to employ a box-shaped container 43 as shown in
FIG. 7, into which long folded webs, sheets or strips of tissue or
folded individual pieces of tissue 44 may be inserted which are
saturated with any of the liquids as previously mentioned. In order
to prevent any liquid which might drain from the tissue 44 into the
container 43 from running out of the latter through the dispensing
slot 45, this slot is provided at a certain distance above the
bottom wall of the container.
If long continuous sheets, webs or strips of tissue are employed,
the container 43 may also be provided with a cutting device to
permit pieces of any desired length to be cut off. The provision of
such a cutting device is especially advisable if the tissue
consists of a fibrous fleece material or any other sheet material
with a relatively high tensile strength.
FIGS. 8 and 9 illustrate how such a cutting device may be designed
and mounted on a cylindrical container similar to one of those as
previously described. On the outer side of this cylindrical
container 46, the covers 47 of which are provided with feet 48 a
cutting bar 49 is secured which has a horizontal surface and is
disposed underneath and parallel to the dispensing slot 50. The
section of the material to be cut off is pressed upon the cutting
bar 49 by a hold-down bar 51 which is secured to a substantially
semicircular plate 52 which is curved around and engages with the
outer surface of the container 46 and is slidably peripherally to a
limited extend back and forth around the container in the direction
of the double arrow 55 between a retracted position, in which a
projection 54 on one end of this member 52 engages into a
substantially semicircular groove 53 in the outer wall of the
container 46, and a hold-down position in which the hold-down bar
51 presses the sheet which has been withdrawn through the
dispensing slot 50 upon the cutting bar 48. For manipulating the
curved plate 52 and the hold-down bar 51 thereon, plate 52 is
provided with a handle 56. Adjacent to the hold-down bar 51, the
container 46 is further provided with a guide bar 57 which extends
along the entire length of the container and carries a blade holder
59 from which a cutting blade 58 with a convex or conical cutting
edge projects which terminates into a sharp point. This blade
holder 59 is slidable along the guide bar 57 and the cutting edge
of blade 58 is capable of cutting in both directions.
FIG. 10 shows a perspective view of a part of a container similar
to that as shown in FIGS. 8 and 9 but provided with a different
support for the cutting device. The curved supporting plate 60
which is pivotably mounted at 61 on the upper part of the
cylindrical container is provided on its free end with a rail 62
which together with the end 63 of the supporting plate 60 presses
the sheet of tissue of the like tightly upon the cutting bar. In
order to prevent the blade holder from sliding off the ends of the
guide bar 64 when the blade holder is moved along the latter in one
or the other direction, these ends of guide bar 64 may be provided
with stop projections 65.
For cutting off individual sections of tissue or the like it is
also possible to employ cutting devices different from those as
previously described. Thus, for example, a cutting blade may be
used which is pivotably mounted at one end and, when pivoted
downwardly, cuts off the saturated material along the cutting edge
of a supporting surface in a manner similar to that of
scissors.
Although my invention has been illustrated and described with
reference to the preferred embodiments thereof, I wish to have it
understood that it is in no way limited to the details of such
embodiments but is capable of numerous modifications within the
scope of the appended claims.
