A dispenser for hygiene paper
The invention relates to a dispenser for hygiene paper containing a hous-
ing, a first roll holder for the reception of a roll with a hygiene paper, a
unit for the moistening of the hygiene paper with a liquid container, with a
moistening roll and with a liquid tank which communicates with the liquid
container (21) and the moistening roll and a guide roll for the hygiene
paper.
Dry toilet paper and moist cleaning tissues are used for hygiene. In use, it
has been found to be disadvantageous that the toilet paper and the
cleaning tissues are presented spatially separately and the moist cleaning
tissues can dry out. This can be very unpleasant in certain situations.
In DE A 26 44 871, a toilet tank is described from which dry and mois-
tened toilet paper can be taken from a dispensing roll. The tank substan-
tially consists of a housing in which a roll holder for the toilet paper is
arranged and a flask which is arranged outside the housing. A deflection
roll for the toilet paper, a transport roll for the toilet paper standing
under
spring action, a liquid container which communicates with the flask and a
moistening roll which is connected to the liquid container line-wise are
arranged in the tank. The toilet paper is guided over the deflection roll and
the transport roll and is held by these at a member with a tear-off edge.
Dry toilet paper can be pulled off in this position. To moisten the toilet
paper, the toilet paper is brought - against the spring action - into contact
with the roll standing in line-wise connection with the liquid container.

The disadvantages of the tank can be seen in the
fact that the toilet paper is moistened by pulling the
toilet paper against the spring action, with the degree of
moistening depending on the pull-off speed. Toilet paper
can thereby by moistened only partly or too strongly. With
too high a pulling force, the moistened toilet paper can be
torn or the dry toilet paper can be torn off outside the
perforation and is consequently unusable. The tank is not
suitable for the use of non-perforated hygiene paper from
the roll. The reason for this can be seen in the relatively
high tear strength of the hygiene paper.
It is the underlying object of the invention to
provide a dispenser for hygiene paper which does not have
the aforesaid disadvantages.
According to an aspect of the invention, there is
provided a dispenser for hygiene paper, comprising a
housing; a roll holder for mounting a roll with a hygiene
paper; a unit for moistening the hygiene paper and having a
liquid container, a moistening roll, and a liquid tank which
communicates with the liquid container; a guide roll for the
hygiene paper; a second roll holder for mounting a roll with
a second hygiene paper which is arranged beneath the first
roll holder; a dispensing unit with a transport roll for
transporting the second hygiene paper, the transport roll
being in contact with the moistening roll through
intermediary of a layer of the hygiene paper; a drive unit
for the transport roll; and a control unit for the drive
unit, wherein the guide roll and the transport roll are
freely rotatably supported on a holder, and the holder is
pivotably arranged at the housing.
According to another aspect of the invention,
there is provided dispenser for hygiene paper or cleaning

are arranged at the housing; wherein the dispenser further
comprises a hood pivotally arranged on the housing for
covering the roll with the hygiene paper; wherein a guide
roll for the hygiene paper is arranged between the
moistening unit and the roll with the hygiene paper upstream
of the transport roll and the moistening roll, and wherein
the transport roll lies on the moistening roll with the
hygiene paper arranged therebetween; wherein the housing
comprises a base housing, an insert part, and means, for
releasably connecting the base housing and the insert part,
and wherein the hood covers the insert part and is pivotally
arranged on the insert part.
According to a further aspect of the invention,
there is provided dispenser for hygiene paper or cleaning
tissues, comprising a housing; a roll holder for receiving a
roll with a hygiene paper; a unit for moistening the hygiene
paper and having a liquid container with a moistening roll
and at least one liquid tank which communicates with the
moistening roll; a unit for dispensing a moistened hygiene
paper and having a transport roll; and a drive unit for the
transport roll, wherein the roll holder and the liquid tank
are arranged at the housing; wherein the dispenser further
comprises a hood pivotally arranged on the housing for

on the moistening roll with the hygiene paper arranged
therebetween, wherein the guide roll and the transport roll
are rotatably arranged in the hood.
It is the underlying idea of the invention to make
available by means of a dispenser dry hygiene paper or to
present moistened hygiene paper, which can be used as toilet
paper or as a cleaning tissue after the tearing off. There
are provided for this purpose, roll holders for the
respective hygiene paper arranged at a housing, a unit for
the moistening of the hygiene paper with a liquid tank, a
liquid container and a moistening roll, which communicate
with one another, a unit for the dispensing with a transport
roll for the transport of the hygiene paper, the transport
roll being in contact with the moistening roll through the
intermediary of a layer of the hygiene paper, with a drive
unit for the transport roll and a control unit.
The advantages which can be achieved with the
invention can substantially be seen in the fact that
commercially available dry toilet paper is
CA 02465343 2004-05-10
3
made available and moistened hygiene paper is dispensed usable as
cleaning tissues and in that the dispenser is simply made and is simple to
handle.
It is of advantage for the housing to consist of a base housing and an
insertion part which are connected via plug connections, for three liquid
tanks to be arranged at the base housing and for the insertion part to
include the liquid container. The servicing and in particular the cleaning
of the dispenser is thereby facilitated.
A hood with a means for the separation of the hygiene paper can be pro-
vided for the covering of the roll with the hygiene paper and of the liquid
container. The wet portion of the dispenser is thus covered and the possi-
bility is provided of using both perforated and non-perforated hygiene
paper.
If the guide roll and the transport roll are rotatably arranged in the hood,
the hygiene paper can easily be inserted in an advantageous manner when
the hood is pivoted downwardly.
The invention will be explained with reference to the enclosed drawings in
the following.
