Description
This invention relates to individually packaged adhesive bandage
units of the type, in which each unit comprises an adhesive bandage
and a package unit therefor affording a sterilized adhesive bandage
which may be readily applied to a minor cut or abrasion. In one
aspect the invention relates to an improved package for the
bandages affording improved handling ease when removing the bandage
from the package and when applying the same to the finger or other
portion of the body without necessitating contact with the adhesive
or the dressing during such application.
Bandages of the type of the present invention have previously been
packaged between wrapper sheets or panels which are adhered to each
other and separable to afford removal of the bandage. It has also
been well known in the art to place the tacky adhesive-coated
surface of the backing strip forming the bandage against a treated
surface of one panel to support the bandage. Likewise, it is well
known in the art to provide a tab on one or both of the packaged
panels permitting the same to be grasped and separated, thus
exposing the adhesive bandage sandwiched therebetween.
It is interesting to note however that in the prior art adhesive
bandage packages, the adhesive-coated base of the bandage is
generally not applied to a continuous uninterrupted extent of a
package panel affording manufacture of this bandage package by
production of the individual bandages, the application of the
individually formed bandages in spaced-parallel relation on a low
adhesion surface of a continuous strip or carrier web of panel
material, the application of a tab to the exposed surface of the
backing strip opposite the adhesive-coated surface applied to the
carrier web, and overlying the carrier web with second strip of
material, sealing the second strip to the carrier web, and
separating the individual packages. Thus, the present invention
provides a bandage and package which is readily manufactured
because of the subsequent laminating steps in the production
thereof and the ease of removal and application of the packaged
bandage.
The adhesive bandage package of the present invention comprises an
adhesive bandage and an envelope therefor. The bandage includes a
backing strip having a tacky adhesive coating on one surface
thereof and a generally centrally disposed dressing. The
adhesive-coated surface of the backing strip is applied to a low
adhesion surface of one panel of the package. A separating handle
is adhesively secured to the backing strip for the bandage on the
side opposite the adhesive-coated surface. This handle member
comprises a length of strip material having opposed ends and an
intermediate adhesive coated area, which area is secured by said
adhesive to the backing strip adjacent one end thereof. A second
package panel is disposed over the bandage and the removable handle
and is bonded to the first panel sandwiching the bandage and handle
therebetween.
The present invention will be more fully understood after reading
the following detailed description which refers to the accompanying
drawing wherein:
FIG. 1 is a plan view of the bandage package of this invention;
FIG. 2 is a view in perspective of the package partially opened to
expose one end of a bandage;
FIG. 3 is a longitudinal sectional view of the bandage package of
FIG. 1; and
FIG. 4 is a perspective view of the bandage attached to a finger
showing the applied bandage and removal of the handle member.
The adhesive bandages 6 which are packaged in accordance with the
present invention generally comprise a backing layer or strip 7 of
suitable material such as a plastic film which is coated on one
surface with a tacky pressure-sensitive adhesive material 9 and has
a gauze pad or other dressing 10 centrally positioned on the
adhesive-coated surface. The backing strip 7 of the bandage of the
present invention may be any suitable film material treated to
provide for adhesion of the tacky pressure-sensitive adhesive
thereto. The pad or dressing 10 may be absorbent or nonabsorbent,
woven or nonwoven, fibrous or nonfibrous; and may be made from such
diverse materials as cotton or synthetic fiber gauzes, felts of
cotton, wool and synthetic fibers.
The bandage 6 is packaged between two package panels or halves, 16
and 17. The panels 16 and 17 protect the bandage and are suitably
bonded to each other to afford a hermetically sealed package for
the bandage.
The panel 16 is made of paper or a thermoplastic film which may
naturally have a low adhesion surface or which may be treated or
coated on one side with a cohesive substantially nonadhesive low
adhesion material. This one surface of the panel 16 is disposed in
contact with the tacky pressure-sensitive coated surface of the
backing strip of the bandage. The panel 16 extends beyond the
periphery of the backing strip and extends to a greater degree
beyond one end of the backing strip than the other.
A removable bandage supporting handle 19 is adhesively secured to
the backing strip on the side thereof opposite the adhesive-coated
surface adjacent one end of the backing strip. This handle is
formed of a narrow strip of material having on one surface an area
20 coated with a pressure-sensitive adhesive 23. The
adhesive-coated area 20 is an intermediate area of the strip of
material and affords thereby a tab 21 at one end which extends
beyond one end of the bandage to which the adhesive-coated area 20
is applied. The opposite end of the strip of material forms a
second tab 22 permitting release of the handle from the bandage
backing strip after application of the bandage to the body.
The second half or package panel 17 is disposed over the bandage
and the removable handle 19 and is bonded to the first panel 16.
The second panel 17 may be formed of a material such as treated
paper or film. The panels 16 and 17 are sealed along the
longitudinal peripheral edges and along one end or transverse
peripheral edge. They are bonded at 24 along the second transverse
edge, which second edge is adjacent the end of the package to which
the handle is secured, a distance spaced inward from the peripheral
edge to form a free end on each panel 16 and 17 in opposed relation
to aid in opening the package.
As shown in FIG. 2 the parts of the package are separated by
grasping a free end of each of the panels 16 and 17 in each hand
and pulling the same in opposite directions to cause a separation
of the two panels at said one end and progressively separating the
two panels along the longitudinal peripherally secured edges.
Continued movement of the panel 17 from the panel 16 exposes the
adhesive bandage 6 secured to the panel 16. Upon completing the
separation of the panel 16 from the panel 17, or at least to the
other transversely secured end, the bandage 6 is exposed. The
handle 19 for separating the bandage 6 from the panel 16 is also
exposed. The tab 21 of the strip material may now be grasped
readily. The adhesive-coated area 20 of the strip of material
forming the handle 19 has a greater adhesion for the backing strip
7 forming the bandage 6 than the adhesive-coated surface of the
bandage has for the support surface of the panel 16. Grasping the
exposed tab 21 thus readily lifts the bandage from the panel 16
separating the tacky pressure-sensitive adhesive-coated bandage
from the low adhesion surface of the panel 16. While maintaining
the grasp with one hand on the tab 21 the bandage may be placed
against the body to apply the dressing 10 over the wound. The free
end of the bandage may be applied and then the supported end may be
applied. With the bandage in position with the dressing over the
wound, the pressure-sensitive adhesive-coated surface of the
bandage is secured to the body or back onto the free end of the
bandage. At this stage, the tab 22 may be grasped between two
fingers and drawn off the end of the bandage to peel it from the
backing strip of the bandage.
The bandage of the present invention is easily manufactured by the
continuous process of laminating the members. The bandage is first
formed by coating a web of the backing strip with a suitable
adhesive having good cohesion for one surface of the backing strip
and laminating a dressing centrally thereto. The individual
bandages are then formed by diecutting the strip. The severed
bandages are applied in spaced-parallel relation along a continuous
strip of material having a low adhesion surface from which the
panels 16 are formed with the adhesive-coated side of the bandage
against the low adhesion surface of the material. The handles are
applied by placing the adhesive-coated sections of strip material
to the bandage adjacent one end, with the tab 21 extending beyond
the end of the bandage. The spaced bandages with the applied
handles are then covered by a strip of material from which the
panels 17 are formed. The laminations are then moved through a
sealing and diecutting member where the panels 16 and 17 are
secured together about the periphery of the bandages as by heat and
pressure sufficient to soften the thermoplastic and bond it with
the fibrous material of member 17. The individual bandages are
die-cut by severing the strips at a bonded seam between the
successive bandages.
