Description
BACKGROUND OF THE PRESENT INVENTION
The present invention relates to a strip package with means for
exposing adhesive zones which are arranged on a carrier and covered
by protective foils. The present invention can preferably be used
for packages of adhesive bandages or plasters and will be described
in the following with reference to this particular application,
without however being limited thereto.
Conventional adhesive bandages comprise a strip-like carrier having
on one surface an adhesive layer on which is centrally located a
dressing pad and defining self-adhesive binder zones which extends
on each side of the dressing. Until the moment of use, the adhesive
zones are protected by protective foils which are intended to be
pulled off before the bandage is used. The removal of these
protective foils is troublesome and generally requires the use of
both hands. Furthermore, there is a risk that the surface of the
wound would be irritated when the bandage is applied because the
dressing must usually being applied on the wound first thereafter
removing the protective foils by pulling them in opposite
directions away from the wound. Furthermore, there is considerable
risk that the dressing pad will not be correctly placed over the
wound since removing the protective foils is difficult.
It is the object of the present invention to provide a strip
package in which the removal of the protective foil covering an
adhesive zone is facilitated and in which the disadvantages of the
prior art are overcome.
It is a further object of the present invention to provide a strip
package for adhesive bandages having a central dressing and an
adhesive zone on each side of said dressing, where each of said
zones are covered by a removable protective foil, in which means
for an automatically removal of at least one of said protective
foil is achieved when the plaster is removed from said
packages.
The foregoing objects, others as well as numerous advantages will
be seen from the following disclosure of the present invention.
SUMMARY OF THE INVENTION
According to the present invention a strip package is provided
comprising a base sheeting cover and a strip carrier having on one
surface an adhesive layer at least in part, covered by a removable
protective foil. One end of the foil is attached to the cover so
that said adhesive surface layer will be uncovered during the
removal from the cover.
In a preferred form of the invention the strip carrier comprises an
adhesive bandage having a central dressing and an adhesive zone on
each side of said dressing, each of said adhesive zones being
covered by a removable, protective foil. The bandage is enclosed in
a base sheeting in the form of a casing with one end of the bandage
slighly projecting from an opening in said casing. In order to
achieve the desired removal of a protective foil one of these foils
is attached inside the casing adjacent to the opening so that the
appropriate adhesive zone will be uncovered during the removal of
said plaster from said casing.
Full details of the present invention are set forth in the
following description and will be seen in the attached
drawings.

FIG. 3 is a perspective view showing a plaster which has been
partially withdrawn from a casing, and
FIG. 4 is a perspective view of a suitable outer envelope for the
multiple pack shown in FIG. 1, and,
FIG. 5 is a view similar to FIG. 2 showing a modification of the
pack.
DESCRIPTION OF THE INVENTION
The multiple pack shown in FIG. 1 comprises a number of adhesive
bandages 2, each in its own enveloping casing, located side by
side. The various wrapper spacers or casings 1 can be separated
from each other along their common side edges 3. For this purpose
the side edges 3 may be provided in known manner with perforations,
slits or the like. The individual casings 1 suitably consist of two
endless sheets 4,5 of material, for example plastic, paper, such as
COSIL paper, aluminium or the like arranged one on top of the
other. To provide the casings, these sheets are joined together by
means of adhesive, welding or in some other way depending on the
choice of material, within an area along their two opposite
longitudinal side boundaries 6, 7 and the bottom boundary 8. In
this way casings 1 are produced adjacent each other, which are open
at one end 9 and can be separated from each other. The adhesive
bandages 2 may suitably be inserted in the casings 1 during
production of the multiple pack, in which case the adhesive
bandages 2 could easily be applied between the endless sheets of
material 4,5 before they are joined together. The bandages 2 are
arranged in such a way that one end 10 projects slightly from the
finished casing and that the opposite end 11 is located within the
enveloping casing at a distance from the lower boundary edge 8 of
each casing.
In the embodiment shown in the drawings the bandages 2 consist
conventionally of a striplike carrier 12 having an adhesive layer
on one surface providing a self-adhesive surface zone 13, 14 on
each side of a pad-like dressing 15 arranged approximately
centrally on the carrier 12. The adhesive layers 13, 14 are
protected in conventional manner before the bandage 2 is used, by
covering them with removable protective foils 16,17 which overlap
each other and cover the dressing pad 15 so that this is also
protected.
In order to enable forcible exposure of at least one of the
adhesive zones 13,14 on the bandage 2, e.g.: in the case shown the
adhesive zone 14, a fixing device is provided in the form of a
strip 18 attached in the edge zones 6,7 of the sheet 4 of material
of the casing. The strip 18 extends transversely across the entire
width of the bandage 2 and overlies the overlapping and of the foil
16. This strip 18 is at least partially joined on the side facing
the bandage, to the protective foil 16 covering the adhesive zone
14. The protective foil 16 extends from the outer edge of the
adhesive zone 14 over the pad-like dressing to a point near the
protective foil 17 adjacent the open edge 9. At this point the end
16a of the protective foil 16 projecting over the dressing pad 15
is then suitably folded double along a folding line 19 so that the
free edge 20 of the protective foil 16 when folded is directed
towards the adhesive zone 14 and the upper side of the end 16a thus
folded in the vicinity of the strip 18 is joined to the strip 18.
This attachment between adjacent surfaces of the strip 18 and the
protective foil 16a can be achieved by glueing, welding,
point-welding or the like.
FIG. 3 shows clearly what happens when the bandage 2 is withdrawn
from the casing 1 by pulling on the exposed end 10 while holding
the bottom edge 8 of the casing. Since the folded end 16a of the
protective foil 16 is joined to the stationary strip 18, the foil
will be forcibly removed from the adhesive zone 14 while the
bandage 2 is being pulled from the casing. The bandage 2, with the
adhesive zone 14 thus exposed can then be applied on the intended
spot, after which the protective foil 17 - which still covers the
other adhesive zone 13 - can also be removed from the bandage 2 by
continued pulling, at the same time as the bandage is stretched and
is thus easily attached to the skin while the protective foil 17 is
being removed, to give final attachment of the plaster.
The strip 18 can easily be applied in the form of a continuous
strip of material in the manner described, during manufacture of
the wrapping, such a strip of material being inserted continuously
between the two sheets of casing 4,5 and attached to the edge zones
of the sheet 4 at the same time as the side welds 6,7 are
applied.
The fixing device shown in the form of a strip 18 can of course be
designed in many different ways within the scope of the invention
and have principally the same function. For example the strip 18
may be omitted completely if the protective foil intended to be
pulled off is instead attached to the part of the sheet of material
5 lying over and in contact with said foil.
Furthermore, the end 16a of the protective foil 16 may have
laterally projecting sections which could be attached directly to
one of the inner sides of the sheets of material 4 or 5.
According to an alternative embodiment of the invention, the
bandage 2 need not necessarily be arranged in a casing formed by
two sheets 4,5 of material, but may also be arranged only on a
base, for instance having the same shape as the rectangular part of
the casing shown in FIG. 2. In this case, the strip 18 shown in
FIG. 5 may be used or, for example in the manner described above, a
slightly projecting part 20a of the protective foil to be pulled
off may be attached directly to the base sheeting.
As pointed out above, the invention is not limited to the use
described here although the application of the invention in this
specific field offers considerable advantages. In principle the
invention may be used to quickly expose adhesive zones in many
fields, for example to expose the adhesive surfaces in various
types of tape, adhesive dressings, etc.
FIG. 4 shows a suitable outer wrapping in the form of an envelope
to hold an arbitrary number of casings 1, each containing a plaster
2. These bands or sheets of casings are then clamped at their lower
ends 21, opposite to the open ends of the wrapper pockets 2, in a
wrappping 22 between a lower fold 23,24. They may be clamped in
many ways, for example by means of staples 25, glue or the like.
This envelope, similar to a match-book, can be closed by means of a
front flap 26, the lower edge 27 of the flap 26 being inserted
between the flap 23 and the first row of bandages in order to close
the wrapping.
Various modifications, changes and embodiments have been described
above. Others will be obvious to those skilled in the present art.
Accordingly, it is intended that the present disclosure should be
limited only by the claims appended hereto.
