This invention relates in general to certain new and useful improvements in methods of making packages for small discrete particulate objects, such as medicinal pills and the like.

It has long been a conventional practice to package small discrete particulate objects, such as pills and the like, in cardboard boxes, glass or plastic vials, or small hinged sheet metal boxes, but these methods are not entirely satisfactory for a number or" reasons. In the first place, many medicinal pills, for example, by reason of the physical nature of the ingredients used, do not have sufficient physical strength to stand the shock and abrading action to which they are subjected when packaged in a box or vial and carried about. Furthermore, conventional containers, after being opened, do not protect the contents from contamination and dirt. In fact, when a user opens a bottle of pills, he customarily shakes several of the pills out into the palm of his hand, returning the remainder to the container for later use. Repetitions of this practice obviously tend to contaminate the pills no matter how careful the user may be. Frequently medicinal pills and similar materials contain ingredients which are adversely affected by moisture and conventional containers do not properly protect hygroscopic materials, particularly after the package has been opened and part of the contents removed.

It is, therefore, the principal object of the present invention to provide a package for small discrete particulate objects, such as medicinal pills and the like, which package is simple and economical in construction and which supports each particulate object separately from each other similar object within the package.

It is another object of the present invention to provide a package of the type stated in which the packaged objects are protected from mechanical shock and impact, moisture, contamination, and repeated handling.

It is a further object of the present invention to provide a package of the type stated from .which each of the particulate packaged objects may be separately and individually removed in a quick convenient manner without disturbing or exposing any of the other packaged objects within the package.

It is also an object of the present invention to provide a package of the type stated in which the packaged articles are each separately compartmentalized and thus protected from contact with each other.

It is an additional object of the present invention to provide simple and economical methods for making packages of the type above stated and enclosing the packaged materials therein.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

Referring now in more detail and by reference characters to the drawings, which illustrate practical embodiments of the present invention, A designates a package preferably comprising four identically shaped oblong-rectangular sheets or plies l, 2, 3, i, stamped, die-cut, or otherwise suitably formed from heavy paper or cardboard, and provided with a plurality of circular apertures 5, 6, l, and 8, respectively. The sets of circular apertures are so arranged that when the plies I, 2, 3, 4, are jogged together in precise peripheral alignment, the apertures will fall into marginal registration in the provision of circular pockets 9 diametrally sized for loosely, but snugly, accommodating a discrete particulate object, such as the medicinal pill it, all as best seen in Figure 2.

Adhesively secured across the upwardly presented face of the ply l is a smoothly and tightly stretched sheet of preferably moisture-proof transparent synthetic plastic film ll, such as cellophane, cellulose acetate, a vinyl polymer, Pliofilm, or the like, and adhesively secured in overlying relation upon the upper face of the film H is a cover sheet l2 having circular apertures l3 which are of the same diametral size,

and are in registration with, the pockets 9. The cover sheet l2 may be imprinted with any desired advertising message, such as that indicated schematically in dotted lines in Figure 1.

Adhesively secured upon, and extending tightly and smoothly across, the under face of the ply 4 is a sheet l4 formed, for example, from a metallic foil, such as aluminum foil or the like. Adhesively secured, in turn, upon the under face of the foil sheet [4 is another cardboard ply 15 identical in shape and contour to the plies l, 2, 3, 4, and having circular apertures l6 for marginal registration with the pockets 9. Similarly secured across the under face of the ply I is a sheet I! preferably formed of thin paper, and finally secured across the under face of the sheet I1 is a rear cover sheet [8 formed of heavy paper and provided with a plurality of circular apertures I9 adapted for registration with the pockets 9.

It will be noted by reference to Figure 2 that each pill 10 is snugly housed within its own pocket 9. Furthermore, the combined thickness of the plies l, 2, 3, 4, is very slightly less than the thickness of the pill, so that the upper and lower surfaces of the pill will contact the interior faces of the film Ii and foil sheet 14 with a slight amount of pressure, this pressure being sufilcient to hold the pill L0 snugly as the pack.-

age is moved about, but nevertheless not great enough to crush or otherwise damage the pill it It should be noted in this connection that the sheets II, M, and H are solid or continuous in the sense that they are non-perforated in the region of the pockets 9 so as to form continuous membranes or closures thereacross. Furthermore, the foil sheet H3 may be made of any suitable moisture-proof material provided its tensile strength is somewhat less than the tensile strength of the film I-l. Thus, the pill I0 is housed between two membranes, so .to speak, one of which is relatively more easily ruptured than the other. The thin paper membrane I! should also be more easily rupturable than the film l, but nevertheless sufliciently strong to afford some protection to the film or membrane 14.

When the user desires to remove a pill, it may be pressed downwardly and outwardly with the finger or a somewhat blunt stylus-like rod in the manner shown in Figure 3. If the rod 20 is manipulated in one hand, the other hand can be cupped beneath the particular pill !0 which is being punched out, so that as it leaves the pocket 9 it will drop into the hand. Obviously, none of the other pills In, which are housed in the other pockets 9, will be disturbed or aifected by such removal of a single pill 10. If desired, the package A may be supported edgewise in suitable slotted pedestal 2| by a conventional easel or in any other conventional manner :to provide a counter display, so that a customer may buy one pill at .a time. Counter displays of this type are particularly useful in taverns, bars, filling stations, lunch wagons, small restaurants, roadside diners, and the like for displaying and selling individual doses of headache tablets, sleep-combating caffeine tablets, indigestionrelieving antacid tablets, or breath-sweetening deodorant tablets.

It is also possible to provide a modified form of package, as shown in Figure 4, comprising a rectangular container element A, which is in all respects substantially identical with the previously described container ,A except that it is smaller and contains a lesser number of tablets or pills. Provided for snug-fitting slidable disposition around the container element A is an open-ended cover-slide B having spaced parallel top and bottom walls 22, 23, marginally connected by side walls 24, 25. For convenience, the top and bottom walls 22, 23, are provided centrally of their transverse margins with finger-cuts 26 to facilitate sliding insertion and removal of the container element A.

The method or process of manufacturing containers in accordance with the present invention is schematically illustrated in Figures 5 to 15, inclusive, and comprises the following sequence of operations. A back member or sheet 30 is die-cut or otherwise formed from a suitable piece of paper and a plurality of circular apertures 3i are stamped therein. Depending upon convenience, the sheet 30 can be blanked out or out to size in one operation and the apertures 3i stamped out in a second operation, or the blanking and aperture-forming can be combined in a single operation. Similarly, the series of interiediate plies having circular apertures 33 may be formed from cardboard or other similar material. The plies 32 are the same size and shape as the back sheet 30 and the apertures 33 are sized and positioned for precise registration with the apertures 3|. In making the type and of containers previously described, it is, of course, necessary to provide five such plies. In addition, a non-perforated sheet of foil 34, a non-perforated sheet of thin paper 35, and a non-perforated sheet 36 of the transparent film, such as moisture-proof cellophane, are also out out to the same peripheral size as the back sheet 36 and plies 32. Finally, a cover sheet or front member 3'! is out, stamped, or otherwise formed from a suitable grade of paper having circular apertures 33 and conforming both in peripheral contour and aperture-location to the back sheet 30. These various components are shown in Figures 5 to 10, inclusive.

Thereupon, two of the cardboard plies 32 are each surface-coated upon a single face with an adhesive either by hand or by being fed through a suitable glue-spreading machine, and, when adhesively coated, are brought together with their adhesive-coated faces touching and jogged into precise marginal registration. Thereupon, one of the exposed faces of one of the cardboard plies 32 is coated with a suitable adhesive having an affinity for metallic foil and the foil sheet 34 applied in smooth overlying marginally registering relation thereon. Thereupon, another cardboard ply 32 is similarly coated with an adhesive having an affinity for metallic foil and applied upon the then exposed face of the foil sheet 34. The thin paper sheet 35 and the back sheet 30 are surface-coated with adhesive and applied in successive order upon the last-mentioned cardboard ply 32. Finally, the assembled plies 32, foil sheet 34, paper sheet 35, and back sheet 39 are placed in a suitable jig or fixture and pressed until dry or, at least, firmly consolidated into a container back-assembly or unit 39 having a plurality of circular pockets 40.

Two cardboard plies 32 are similarly assembled with the cellophane sheet 36 and the cover sheet 31 to form a container top-element 4|, as shown in Figure 12.

Thereupon, medicinal pills 42 are manually or otherwise suitably inserted into the pockets 40. As will be seen by reference to Figure 14, the pills 42 are substantially thicker than the pockets 0 of the back-assembly .38 and, therefore, protrude upwardly therefrom. The interior face 43 of the top-assembly M is then surface-coated with a suitable adhesive and placed down over the top of the back-assembly 39 in precise marginal registration therewith, as shown in Figure 15, and the assembly thus formed is then placed under suitable pressure until dry or firmly consolidated to form the finished package in which each medicinal pill t2 is securely sealed within its own separate compartment. In this connection, it should be pointed out that the adhesive used in this final assembly operation should be carefully applied, preferably by a roller or other suitable means, so that there will be no substantial excess of adhesive to be squeezed into the pockets and onto the pills. However, since it is always possible that a slight amount of adhesive may contaminate a few or more of the pills 42 as a result of careless workmanship or sloppy technique, it is highly desirable that the adhesive used in this final operation be edible, so that it will have no damaging effects in the human system. It is also possible to avoid this difficulty irrespective of the chemical constituency of the adhesive by applying the adhesive in carefully defined areas by means of printing rollers, printing plates, or similar means.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the package and in the steps of its production may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
