The invention relates to a packaging wrapper for hygiene or wiping products,
such as handkerchiefs, household or other hygiene tissues or nonwovens. The
packaging wrapper comprises an opening for removal of the products and
preferably a sealing mechanism. The opening can be formed and placed
anywhere on the package. The packaging wrapper can be configured as a
pouch. The packaging wrapper comprises preferably also a sealing flap that at
least partially overlaps the opening for removal of the hygiene or wiping
The conventional prior art package or packaging wrapper for a hygiene or a
wiping product often includes a flexible material, such as a wrapper of a thin
plastic foil, a nonwoven or a nonwoven fabric coated with a plastic film,
containing for instance handkerchieves or the like. Packaging wrappers for
paper handkerchiefs are commercially available in a variety of versions and
they are provided with a removal opening for the products. The paper
handkerchiefs are conventionally packed in bundles of for example ten
handkerchiefs or so in a wrapper.
One problem with the conventional prior art package for hygiene or wiping
products is that it can not be readily seen or found in the dark. Often, the
consumer and user will have an urgent need for the products in question,
especially during illness, which in turn often tends to be treated in semidark or
dark areas, and especially during night time. The need for such products are
usually also stronger during night time, including evenings and mornings,
when mucus membranes tend to be more swollen and phlegm and mucus quite
annoying. The need for hygiene or wiping products is of course not limited to
illness situations, on the contrary, these kind of products are frequently used in
any possible situation, and if there is not enough light, then the product is
difficult to find and see. For instance, when small children are concerned there
are often vomits, druels, dregs as well as gruel or milk spillage involved. But of
course the hygiene or wiping products could be used for anything that the
consumer and user could come up with and it would neither be possible nor
appropriate to mention every possible usage.
Another problem is that many persons are easily disturbed by annoying noises
and sudden changes in lightness or darkness. The rest, calmness, or the sleeping
period is thus then easily disturbed. In order to find a package of hygiene or
wiping products in the dark, it is either required to search for it in the dark,
which is time consuming and involves the risk of being noisy, or to turn on the
light, if it is possible, thus risking to disturb or wake up others including the
user himself that also could be adversely affected by the sudden change in
This can be troublesome, especially when someone that does not easily fall
asleep or come to rest again is woken or disturbed. The parties concerned could
be anyone being in the vicinity as well as the person himself. It could be infants,
children, a mate or partner, patients, travelling companions, animals or anyone
that is not to be disturbed by noises or changes in light caused by the user of the
product. The environment could be anything from resting or sleeping areas or
any other dark areas in the family circle to any other public place, such as
hospitals, nursing homes, daycare centers, train wagons, buses etc. The persons,
the situations, and the circumstances could be anything, from avoiding noises,
when searching for the product, or avoiding turning the ligths on or any other
sudden changes in light, to occasions when it is actually impossible or difficult
to achieve enough lighting.
The purpose of the invention is to reduce or remove any of the above
mentioned problems. The invention is based on providing a packaging wrapper
for hygiene or wiping products, especially for handkerchiefs, household or
other hygiene tissues or nonwovens, that consists of or comprises at least one
phosphorescence part exhibiting an afterglow in the dark. The phosphorescence
part or parts comprises a phosphorescent or luminescent substance. The
packaging wrapper comprises a package material and an opening for removal
of the products, and the opening can be anywhere on the package and of any
form. Preferably, the opening includes a sealing mechanism and/or a sealing
flap that at least partially overlaps the opening for removing the products.
It is to be understood that the invention is not limited in its application to the
details of construction and the arrangements of components set forth in the
The invention permit seeing at any time a packaging wrapper for a hygiene or a
wiping product, such as a package of tissues, eg handkerchiefs or the like. In
one preferred embodiment, the packaging wrapper is configured as a pouch,
and suitable for all kinds of thin packaging material, including plastic, paper,
nonwoven or similar materials. The opening can be formed on an elongated
side of the packaging wrapper or any other convenient location on the package.
In the event of being in the dark or without the normal daylight or electric
power supply, a package for hygiene or wiping products with a luminescent
substance will glow for an extended period of time, helping one to find the
wanted or desired package without having to turn on the lights on. This is a
convenient way to fill any need there might be for a hygiene or wiping product
without having to turn the lights on and thereby be a nuisance and it is also a
good way to achieve independence from light sources.
Not only the fact that the light or rather the darkness is kept unchanged, but
also any disturbing noise is avoided since the desired package glows in the dark
and may be found in a quick and easy manner. In addition, if the package of
handkerchiefs, or the like, is accidently dropped or laid down, it is easily
located in the dark environment when it has a glow in the dark property.
It is good if the phosphorescence of the phosphorescent or luminescent
substance provides a long afterglow in the dark after the stimulus is cut off or
has disappeared. However, the exact duration of the afterglow in hours is not
limiting in any way. The choice of the phosphorescent or luminescent
substances can easily be altered by the skilled person depending on the desired
result both in brightness and afterglow duration.
The phosphorescence part may be disposed on a surface of the package or
dispersed throughout the material which forms this part. The material that
forms the phosphorescent part may also be included within the package as well
as being a treated, an amended, an added, an integral or an independent part of
the package. The phosphorescent or luminescent substance may be a part of
and/or a constituent of the package material.
The phosphorescent or luminescent substance can be used as a component in
the compositions of the package material. This means for example that the
package material can consist of or may include for instance molded, extruded
or otherwise formed plastic articles, as well as any non-woven articles including
a phosphorescent or luminescent substance of the invention which exhibits an
afterglow in the dark.
According to another embodiment, the phosphorescent or luminescent
substance is applied to the surface of the package material. According to the
invention, the luminous substance may be connected with the package in at
least one area of said package in any manner. The phosphorescent or
luminescent substance or the phosphorescence part or parts are formed by
colouring, pigmentation, coating, printing, etching, glueing, embossing,
stamping, riveting, pinching or welding by way of fastening, adhesion,
adsorption or absorption to or into the packaging wrapper.
Further, another embodiment discloses that the phosphorescence part or parts
of said package are printed in any possible manner with an ink, or the like,
comprising a phosphorescent or luminescent substance.
However, any method that will include the luminescent substance in the
package or that could be used to apply the substance to the package is of course
a part of the invention. Also, different methods could be combined, such as for
example when the phosphorescent or luminescent substance is dispersed
throughout the material which forms the phosphorescence part, that material
may be added, applied or disposed on the surface of the package in question.
The phosphorescent or luminescent substance can also be blended, mixed or
attached to the sealing mechanism of the package. The sealing mechanism may
include a pressure-sensitive adhesive or a hook- and loop fastening system or
other conventional sealing mechanisms.
The phosphorescent part or parts of the package can be designed to constitute a
form or a shape anywhere on the package. The form or shape could be a
logotype, a design, a picture, a written message, a trademark, a company name,
or in any way a descriptive or figurative pattern or design, sign, symbol or the
The present invention relates to a packaging wrapper for a hygiene or wiping
product, such as soft paper, tissue, or nonwoven. The invention could be
embodied in various ways. In the following, the term soft paper, tissue or
nonwoven does not only refer to the raw material as obtained from the paper or
nonwoven machine, but also covers the corresponding further processed
products, since there often is no strict borderline to distinguish the same.
Nonwovens may also be called textile-like composite materials, which
represents flexible porous fabrics that are not produced by the classic methods
of weaving warp and weft or by looping; but by intertwining, cohesive or
adhesive bonding of fibers, or a combination thereof. The nonwoven material
can be formed of natural fibres, such as cellulose or cotton fibres, but can also
consist of synthetic fibres, such as PE, polypropylene (PP), polyurethane (PU), a
polyester, nylon or regenerated cellulose, or a mix of different fibres. The fibers
may for example be present in the form of endless fibers or prefabricated fibers
of a finite length, as synthetic fibers produced in situ or in the form of staple
fibers. The nonwovens according to the invention may thus consist of mixtures
of synthetic fibers and cellulose fibrous material.
Hygiene or wiping products primarily includes all kinds of dry-creped tissue
paper, as well as wet-creped paper and cellulose or pulp wadding or all kinds
of nonwovens, or combinations, laminates or mixtures thereof.
Typical properties of tissue include the ready ability to absorb tensile stress
energy, their drapability, good textile-like flexibility, properties which are
frequently referred to as bulk softness, a high surface softness, a high specific
volume with a perceptible thickness. As high a liquid absorbency as possible
and, depending on the application, a suitable wet and dry strength as well as an
interesting visual appearance of the outer product surface. These properties,
among others, allow tissue paper to be used for example as cleaning wipes:
paper or nonwoven wipe, windscreen cleaning wipe, kitchen paper, etc,
sanitary products: e.g. toilet paper, paper or nonwoven handkerchiefs,
household towels, towels, cosmetic wipes: facials and as serviettes or napkins
just to mention some of the products that can be used.
The hygiene or wiping products may be unfolded or folded, interleaved or
individually placed, stacked or rolled, connected or not, in any suitable manner.
The relevance thereof is not important to the object of the invention.
The packaging wrapper can be made of a variety of flexible, plastic film
materials, such as polyethylene, polypropylene or polyester just to mention
some materials that can be used. The package or the cover may also be made of
any flexible, nonwoven material. The flexible material can also have the
capability of forming a barrier between the tissues and the environment to keep
the tissues clean and dry. The material is normally produced and printed as
continuous sheeting and then cut into such sections so that the desired package
can be formed therefrom.
Luminescent or phosphorescent substances as such are well known and they
remain luminous with a soft, slowly decaying radiation once they have been
excited. Such substances can generate a useful level of luminous flux for several
hours when placed in the dark after having absorbed sunlight or artificial light
of suitable wavelength.
The herein referred luminescent or phosphorescent substance or material is to
be understood as though the invention comprises any material that glows or
emits lights. With regard to this terminolgy, phosphorescent material in the
manner used here comprises chemiluminescent and bioluminescent materials
as well as every substance that emits light and exhibits an afterglow after being
exposed to heat, light, electrical power, discharge or signals without any
substantial rise in temperature.
The luminescent substance may be selected either as one which produces the
highest level of visible radiation output as a result of decay of said luminescent
pigment in the absence of visible light, or as one which produces an output for
an extended, predetermined period. The combination of the two effects must of
course be balanced and adjusted to the usage and the requirements. The
selection of the luminescent or phosphorescent substance is not critical or
essential to the invention, however a careful choice allows the specific purpose
to be achieved. The luminescent substance is most preferably selected to emit
the colour yellow or yellow-green, amongst the range of available colours that
probably has the most striking effect on the eye. But it could of course be of any
Exemplary glow in the dark materials include often phosphorescent materials
which have the property of continuing to emit light for an extended period of
time after excitation. Phosphorescent materials have earlier been used in a
variety of commercial applications because they have the property of
continuing to emit light for an extended period of time after excitation.
Phosphorescent pigments have, therefore, been used in warning signs; marking
of vital machinery; dial illumination; directional signs on walls of underground
stations, garages, hallways; and applied to helmets as used in fire departments,
accident prevention, etc. Phosphorescent pigments have also found application
for use on protective clothing, sports equipment and a variety of toys where the
effect of glowing in the dark provides amusement, ornamental or safety
In the event of a blackout or other emergency in which the normal electric
power supply is cut off, objects coated with phosphorescent paint will glow for
extended periods of time, helping to demarcate walkways, stair mountings, exit
doors and the like if they are so coated. Phosphorescent substances have also
been employed for door knobs, corner indicators, switches, bell pushes, ash
trays, watch faces and stands, medicine bottles, ornamentation, storage, hearing
protective devices, identification labels.
US 4,165,002 concerns authenticating a paperboard package with a
phosphorescent indicator. However, even though phosphorescent materials are
known to be used for different articles for a long time, it has not been known to
use such substances on packaging wrappers for hygiene or wiping products.
Phosphorescent materials include a phosphor which has been artificially
prepared and has the property of luminescence when activated by appropriate
wavelengths of light. A variety of phosphors are available for use in providing
luminescence when activated by an appropriate light source. Commercially
available phosphors include silicates, metal aluminate oxides, alkaline earth
aluminate phosphors, alkaline earth metal aluminate oxide phosphors, sulfides,
zinc sulfide, metallic zinc sulfide (eg cadmium), alkaline earth sulfides and
various rare earth compounds. The compunds can be with or without
activators, coactivators or compensators. Activators are often used to provide
the desired rapid activation of the phosphorescent or luminescent substance.
Many phosphorescent materials and more particularly phosphors are
commercially available and emit different colours and continue to emit
radiation for different periods of time after they are removed from ambient
light. Accordingly, the selection of particular phosphors or combination of
phosphors to provide predetermined characteristics is another factor that can be
employed in the present invention to create different kinds of a phosphorescent
part or parts of the package.
The phosphorescent pigments may be incorporated into a variety of carriers
that can be a part, a consituent, a component of, incorporated, integrated,
applied, added, connected or attached to the package. The list of different
methods that could be used would be large. Therefore, only some will be
mentioned even though the scope of the invention covers all conventional
methods used in order to achieve a package of hygiene or wiping products
comprising at least one phosphorescence part.
In one embodiment of the invention, the phosphorescent or luminiscent
material is applied or disposed on the surface of each predetermined part of the
package in the form of any predetermined printed text, form, shape, message or
This can be easily accomplished by dispersing or disposing the phosphorescent
or luminiscent substance in a suitable medium and applying the substance to
the surface of the predetermined phosphorescence part or parts by any known
printing methods, such as silk screening, thermoprinting, or off set techniques.
If a material has an inherent adhesive capability then, in such cases, the
phosphorescent or luminescent substance can be applied or coated directly on a
surface of such material.
Other methods that could be used would be different colouring techniques,
pigmentation, etching, coating, glueing, embossing, stamping, riveting,
pinching, welding or any other methods that would cause fastening, adhesion,
adsorption or absorption. Of course, even mechanical methods could be used to
apply a phosphorescence part or parts such as different needling techniques,
stapling, sewing and taping.
The predetermined phosphorescence part or parts could also be made in a
material different from the package and then applied to the package, either on
the surface of a package or made to be a part of the package.
The phosphorescence part or parts may also be achieved by using a package
with different layers. A phosphorescent or luminescent layer can be secured
with its luminescent surface and then covered by image means. The image
means forms an image on its surface via a plurality of image defining opaque
and translucent areas. The opaque areas of the image means prevent the light
coming from the photons emitted from the excited atoms of the luminescent
substance from passing through the opaque areas of the image means. The
translucent areas of the image means allow the emitted light from the
luminescent substance to pass through the translucent areas of the image
A protection pattern could also be attached to the surface and, for example,
extend over substantially the entire surface to establish a visual shield that
creates imaginary protection. The pattern of the phosphorescent substance,
when exposed to light and placed in a dark environment, emits light for a
period of time, whereby the pattern is shown. The pattern has open spaces
containing phosphorescent substance. In this way a glow in the dark image may
be produced. Securement means is also provided for securing the luminescent
layer to the image means.
Further, the phosphorescence part or parts could also be applied to the sealing
mechanism in different ways. The phosphorescent or luminiscent substance
with or without any carrier could be blended in, mixed with or attached to the
sealing of the package. The sealing mechanism could involve a pressure-sensitive
adhesive, a hook- and loop fastening system or a tape or the like. The
sealing mechanism can of course inlude a sealing flap that is fastened in any
The invention also comprises any evidently suitable method or methods that
will involve the process of achieving a package for hygiene or wiping products
that comprises or consists of one phosphorescent part or several
phosphorescent parts. The invention is capable of other embodiments and of
being carried out in various ways.
