Claims
I claim:
1. An article of manufacture comprising a thin sheet of transparent
plastic material formed with parallel corrugations extending across
the sheet between opposite edges thereof, a pad member adhering to
said sheet, said member having a pressure-sensitive adhesive
coating on the surface thereof contiguous to said sheet, said
coating being in full and uninterrupted contact with the
corrugations of the surface sheet, said pad member being readily
removable from said sheet.
2. The mounting of claim 1, wherein said sheet is of evenly
corrugated cellophane.
3. The mounting of claim 1, wherein said sheet is of evenly
corrugated acetate material.
4. The mounting of claim 1, wherein said sheet is of evenly
corrugated vinyl material.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention or discovery relates to the packaging of articles
having a pressure-sensitive adhesive surface thereon for sale to
the ultimate consumer. In order to protect the adhesive surface and
also maintain the efficacy of the adhesive it is customary to mount
the articles by way of the adhesive surface upon a sheet or card
from which the articles may be removed at the time of use by the
ultimate consumer. The instant invention is directed to a new form
of mounting sheet. While the new mounting sheet is highly desirable
for the packaging of surgical pads such as corn or callous pads,
finger bandages, sheets of adhesive-surfaced moleskin, and the
like, it will be apparent to one skilled in the art that other
nonsurgical articles may also be mounted on the sheet.
2. Description of the Prior Art
For many years it was customary to mount adhesive-surfaced surgical
pads and the like upon a sheet of crinoline but such, due to its
rather open weave, did not fully protect the adhesive surface from
deterioration by contact with ambient air. Later, a laminated card
was used for the mounting of the articles, the card consisting of a
sheet of paper with a sheet of cellophane or acetate film laminated
thereto as set forth in Scholl U. S. Pat. No. 2,209,210. With that
arrangement, however, the articles were not as easy to remove from
the card as is desired, the underside of the articles was not
visible through the mounting, and the card was objectionably
costly. Still later, as set forth in Scholl U. S. Pat. No.
2,493,267 an irregularly crinkled vegetable parchment having a
glazy surface was used as the mounting. This, however, did not
permit visibility through the mounting of the underside of the
articles, and the adhesive surface of an article did not fully
contact the surface of the mounting but rested upon the high points
of the crinkles thereby not being fully protected from ambient air,
and such parchment was also objectionably expensive.
SUMMARY OF THE INVENTION
The instant invention embodies a mounting sheet for
adhesive-surfaced articles which is formed of a thin plastic sheet
of cellophane, acetate sheet, or equivalent material. The sheet is
corrugated and transparent. The mounting may be made by running the
sheet through corrugating rolls in an extremely economical manner.
The article makes full contact of the adhesive with the mounting
and when the article is removed the impression caused by the
corrugations appears in the adhesive surface of the article. The
underside of each article is visible through the mounting and the
articles are very easily removed from the mounting especially if
lifted off the mounting in the direction of the corrugations.
Further, the adhesive surface is fully protected until removal of
the article, cannot be affected by ambient air, and the mounting
itself is far more economical than mountings used heretofore. Thus,
it can be seen that the instant invention solved the problems
involved in the prior art, as above recited, and possesses
advantages not found in the prior art.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a plan view of a mounting embodying principles of the
instant invention showing a pair of corn or callous pads disposed
thereon;
FIG. 2 is a bottom plan view of the structure of FIG. 1 indicating
the visibility of the articles through the mounting;
FIG. 3 is a greatly enlarged vertical sectional view taken
substantially as indicated by the line III--III of FIG. 1, looking
in the direction of the arrows;
FIG. 4 is a plan view of the same mounting carrying a sheet of
moleskin; and
FIG. 5 is a view of the same mounting carrying finger bandages
thereon.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The illustrated embodiment of the instant invention comprises a
mounting 1 in the form of a thin transparent plastic sheet, various
cellulose derivatives, acetate and vinyl sheets being satisfactory
as well as other plastic sheets having the property to release
adhesive thereon without any delamination of the adhesive from the
article carrying it, are satisfactory for the purpose.
By simply passing the sheet through a pair of corrugating rolls,
parallel corrugations 2 may be provided in the sheet. The sheet may
then be cut to any desirable size depending on the size and number
of articles to be carried by the sheet. The mounting therefore is
extremely economical.
In FIGS. 1, 2 and 3 I have shown the mounting with a pair of corn
or callous pads thereon. Each of these pads includes a cover 3
overlying a body part 4 having an affliction receiving aperture 5
therein. On the underface of the body part is a spread of
pressure-sensitive adhesive 6 and, as clearly seen in FIG. 3, the
adhesive follows the undulations of the corrugations so that the
entire adhesive surface is fully protected from ambient air, dust
and dirt, by the mounting 1. As seen in FIG. 2 the mounting is
transparent so that the undersides of the pads are plainly visible
through the mounting.
The pads may very easily be removed from the mounting without any
delamination of the adhesive and without leaving any adhesive
remaining on the mounting. This may be accomplished very easily be
pressing flat the corrugations adjacent the edge of the pad,
bending the mounting at the pad edge, and stripping off the pad in
the direction of the corrugations.
In addition, the mounting is flexible so that the same may be
folded to be placed in a small receptacle in a handbag, and the
mounting cannot in any manner injure other delicate articles
carried in the same handbag.
In FIG. 4 I have illustrated the mounting as carrying a sheet of
moleskin 7 having adhesive on the underside thereof. In FIG. 5 I
have illustrated the commonly known form of finger bandages 8
carried on the mounting. These illustrations are by way of example
only and not by way of limitation to indicate that numerous
articles bearing pressure sensitive adhesive may be utilized on the
mounting to protect the adhesive until time of usage of the
article.
It will be understood that modifications and variations may be
effected without departing from the scope of the novel concepts of
the present invention.
