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. 3. 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. I 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. I 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. I, 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 ofcorn or callous pads thereon. Each of these pads includes a cover 3 overlying a body part 4 having an affliction receiving aperture 5 therein. 0n 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 I. 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 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.
I. 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 I, wherein said sheet is of evenly corrugated cellophane.
3. The mounting of claim I, wherein said sheet is of evenly corrugated acetate material.
t. The mounting of claim I, wherein said sheet is of evenly corrugated vinyl material.
