(54) Device for Eliminating Odors in Refrigerators or the Like
Materials, stored in
refrigerators, often emit strong or less strong odors; and as a result, other
foodstuffs in the refrigerator may take on foreign odors and, thus, suffer a
reduction in the quality.
Therefore, the object of
the invention is to provide a device, which is to be accommodated in the
refrigerator, requires little space and over a prolonged period of time
eliminates or binds the odors, produced in the refrigerator, in a hygienically
safe manner.
This object is achieved
by a perforated and, thus, gas permeable container, which is filled with a
powdery or granular active ingredient mixture, comprising cetyl alcohol, borax,
and sodium bicarbonate, in such a manner that said mixture is in contact with
the air surrounding the container.

Patent
Claims
1.) Device
for eliminating odors in refrigerators or the like, characterized in that said
device comprises a perforated and, thus, gas permeable container (1), which is
filled with a powdery or granular active ingredient mixture (4), comprising
cetyl alcohol (C2H5OH), borax (Na2B4O7
· 10 H2O) and sodium bicarbonate (NaHCO3) in such a
manner that said filling (4) is in contact with the air surrounding the
container (1).
2.) Device,
as claimed in claim 1, characterized in that the active ingredient mixture (4)
comprises 50 parts by weight of sodium bicarbonate, 2 parts by weight of borax
and 2 parts by weight of cetyl alcohol.
3.) Device,
as claimed in claims 1 and 2, characterized in that the active ingredient
mixture (4) is located in an insert (5), the walls (6) of which are provided
with perforations (16); and that this insert (5) can be inserted in an
interchangeable manner in the container (1), which is provided with air
passages (3) and can be closed with a cover (2).
4.) Device,
as claimed in claim 3, characterized in that until the device is used, the
perforated walls (6) are covered with cover films (7), which can be peeled off.
5.) Device,
as claimed in claims 1 and 2, characterized in that the container (1) comprises
two nested container elements (8 and 9) that resemble dual jackets and are
closed on one end and whose inner and outer walls (10/11 and 12/13) exhibit
identical perforations (14), which are configured in such a manner that, when
the container elements (8 and 9) are slid into each other, said perforations
coincide in such a manner that by rotating these container elements in opposite
directions, the opening or closing of these perforations (14) is achieved by
choice.
6.) Device,
as claimed in claim 5, characterized in that the inside walls of the dual
jacket of the bottom container element (9), which contains the active
ingredient mixture (4), are provided with a gas permeable cover (15), which
covers the perforations (14).
7.) Device,
as claimed in claim 6, characterized in that the cover (15) is made of gauze or
a similar close meshed net.
Device
for Eliminating Odors in Refrigerators or the Like
The
invention relates to a device for eliminating odors, which are emitted by
foodstuffs and other materials that are stored in refrigerators or the like.
Such
odors are more or less strong; and as a result, other materials, stored in the
refrigerator, may take on foreign odors and, thus, may suffer a reduction in
quality.
Therefore,
the object of the invention is to provide an inexpensive device, which requires
little space and over a prolonged period of time eliminates or binds the odors,
emitted by the foodstuffs, stored in the refrigerator.
This
object is achieved by a device exhibiting the features, characterized in patent
claim 1.
This
novel device can be put or hung easily into the storage space of the
refrigerator and eliminates or binds any odors, which are produced, for a
number of weeks in a hygienically safe manner. Then the device may be either
replaced in its entirety; or only the active ingredient filling may be
replaced, as in other design models.
Advantageous
embodiments of the invention, in particular also in regard to the mix ratio of
the
active
ingredient filling, are characterized in the dependent claims.
The
subject matter of the invention is depicted in two embodiments in the drawings.
Figure
1 depicts the device in the form of a can-like container;
Figure
2 is a side view of the container, according to Figure 1;
Figure 3 depicts the
active ingredient filling of the container, according to Figures 1 and 2; and
Figures 4 and 5
depict another embodiment with a
ring-shaped container.
The
device, depicted in Figures 1 to 3, comprises a can-like container 1 with a
cover 2, which can be placed on said container. Both the bottom of the
container 1 and expediently also the cover 2 are provided with a plurality of
passages 3 of arbitrary shape.
The
active ingredient filling 4, comprising a mixture of cetyl alcohol (C2H5OH),
borax (Na2B4O7 · 10 H2O) and sodium
bicarbonate (NaHCO3) is located in an insert 5, the outer dimensions
of which match the container 1. Both face sides 6 of said insert are provided
with a perforation 16. In addition, the face sides 6 of said insert can be
provided with a cover film 7, which can be removed and which is intended for
the storage and shipment of said insert. Thus, the filling 4 is then sealed in
an air-tight manner.
In
order to use the device, both films 7 are peeled off; and then the insert 5,
containing the active ingredient 4, is put into the container 1; and the cover
2 is put on said container.
Thereafter,
the device is ready for use.
The
active ingredient 4 can be used in either a powdery or, even better, granular
form. A preferred mix ratio comprises 50 parts by weight of sodium bicarbonate,
2 parts by weight of borax and 2 parts by weight of cetyl alcohol.
The
design model, depicted in Figures 4 and 5, comprises two nested container
elements 8 and 9 that resemble dual jackets and are closed on one end. Both the
inner walls 10 and 11 of these container elements 8 and 9 and their outer walls
12 and 13 are provided with perforations 14, which are configured in such a
manner that, when both container elements are slid into each other, said
perforations coincide in such a manner that by simply rotating these container
elements 8 and 9 in opposite directions, the perforations 14 can be opened or
closed by choice. The active ingredient filling 4 is located in the dual jacket
of the bottom container element 9 and is poured in preferably in the granular
form. In order to prevent the filling from escaping through the perforations
14, the inside walls of the bottom dual jacket are provided with a gas
permeable cover 15 made of a close meshed net, gauze or the like.
In
this embodiment the active ingredient mixture can be refilled again from a
supply package.
For
the sake of completeness it must be added that the invention is not restricted
to the described embodiments, but rather can also be realized in any number of
different ways within the scope of the patent claim.
