The card has a peelable backing and is perforated to enable the peeling to be started. It also has perforated tabs for access to the contents after removal of the backing.

20 Claims, 10 Drawing Figures PACKAGING This invention relates to packaging of medicaments or the like in capsule, lozenge, or pill form, into discrete article enclosures such as are provided by a blister card, and especially to such a package designed so as to be unlikely to be openable by a child of insufficient discretion to treat the contents with due respect.

Blister packaging has become popular in recent years not only for small automotive parts, household articles, and micellaneous hardware but also for medicaments in capsule, lozenge, or pill form. Because the contents are visible and often are brightly colored, children are attracted thereto, with substantial risk of injury if they succeed in opening such a package and ingesting the contents. Accordingly, there is a considerable demand to render such packages too difficult to open for children too young to realize the potential hazard in doing A primary object of the present invention is provision of a blister package readily openable by an adult but not by a child.

Another object is improvement in access closures for blister packages.

A further object is requirement of a specific sequence of several steps for successful opening of blister packages or the like.

Other objects of the present invention, together with means and methods for attaining the various objects, will be apparent from the following description and the accompanying diagrams of a specific embodiment of the invention, which is presented by way of example rather than limitation.

FIG. 1 is a perspective view of a blister card of this invention with the overlying flap partly cut away to reveal the underlying flap and contents in part;

FIG. 2 is an edge view of the same package taken at IIII on the preceding view;

FIG. 3 is a front view of the same package opened flat and with part of the normally overlying flap cut away;

FIG. 4 is a rear view corresponding to FIG. 3;

FIG. 5 is a transverse section, on an enlarged scale, taken at V\/ on FIG. 3; and

FIG. 6 is a longitudinal section, on the same scale as FIG. 5 and taken at VIVI thereon.

FIG. 7 is a rear view of the same package at an early stage of being opened, showing severing thereof along perforations;

FIG. 8 is a like view of the remaining part of the package at a later stage of being opened, showing the backing being peeled off;

FIG. 9 shows the same package at a still later stage, showing the opening of an access tab along perforations; and

FIG. 10 is a fragmentary sectional view of the same package, on an enlarged scale, at a still later stage, showing the pressing of a capsule through the foil covering an access opening.

In particular, the objects of the present invention are accomplished, in a package having discrete article enclosures, such as a blister card for medicaments or the like in capsule, lozenge, or pill form, by means of a first strip having a plurality of blister-like protrusions therein outward from one face and leaving corresponding hollows and openings thereinto at the opposite face thereof, a relatively rupturable second strip adherent to the latter face of the first strip and sealing the openings therein, a supporting card therefor overlying the second strip over the hollow openings and having an openable access tab opposite each such opening, and a peelable backing overlying at least the part of the card containing the access tabs without extending to any edge of the card.

More generally, the invention features the combination of such a peelable backing, a partly underlying perforation or equivalent weakening in the card to facilitate peeling of the backing, such underlying access tabs and such underlying access openings covered by rupturable material.

FIG. 1 shows in perspective, and FIG. 2 in edge view from the bottom, package 10 of this invention comprising overlying rectangular flap 11, underlying flap 13 of the like plan, and narrrow rectangular junction strip 12 interconnecting them. Flap 11 is partly cut away in FIG. 1 to reveal the underlying flap and contents in part-also shown from below in FIG. 2. Protrusions 19 in a transparent blister strip (23, see later views) enclose capsules 18, of which four are shown (spaced in pairs from top to bottom and right to left). Stippling of the area surrounding the capsules in FIG. 1 indicates a foil layer (25, see later views) visible through the transparent blister strip.

FIGS. 3 and 4 show the same package, opened flat, from front and rear, respectively. Rear flap 13, which is plain overall, is largely cut away, but front flap 11 is shown in its entirety. Not previously visible but shown here is diagonal perforated line 16, which crosses from the upper edge to intersect vertical fold perforation 15, thereby outlining corner tab 20 of the flap. As is apparent from the rear view in FIG. 4, the corner tab partly underlies transparent film backing 29 which is generally rectangular but smaller than the flap and does not extend to any edge of the flap. The backing completely covers all four access tabs 28 visible therethrough, each of which is opposite one of the openings left in the blister strip by formation of the protrusions oppositely directed therein.

FIGS. 5 and 6 show, considerably enlarged, sections taken through multiple-layered portions of the package as indicated on FIGS. 3 and 5. First and second layers 21 and 27 of the flap sandwich the non-protruding portions of blister strip 23 and foil layer 25 over and sealing the openings therein. First layer 21 has openings therein to accommodate protrusions 19 of the blister strip and each corresponding hollow holds capsule 18 with contents 22 therein. Each of the access tabs is bounded by parallel rows 26 of perforations perpendicular and joined to opposite ends of slits 24, with neither slit nor perforation along the remaining side.

FIGS. 7, 8, 9, and 10 are sequential views, at stages in opening the illustrated embodiment of the invention, taken looking at the rear side, with hands shown in phantom overlying the views where appropriate. Thus, as shown in FIG. 7, with the respective flaps opened and coplanar, a person can grip flap l1, junction strip 12, and corner tab 20 of flap 13 in the right hand and the rest of flap 13 in the left hand. This enables the tab to be severed along the diagonal perforated line shown previously, together with the junction strip, along the rest .of vertical perforated fold line 15, and flap 11. (The remnant flap is redesignated 13'.) Then gripping the exposed corner of backing 29 with the left hand while holding onto the marginal part of flap 13 not covered by the backing permits the backing to be peeled off, as shown in FIG. 8. Finally, by inserting a fingernail into one of the slits 24, one can grip an access tab and pull it open along perforated lines 26. (The opened tab is redesignated 28'.) Foil 25, which did not rupture when the tab was opened, is exposed through the resulting rectangular opening and continues to cover the underlying capsule. Finally, as shown in FIG. 10, depressing the corresponding blister protrusion with a finger forces the capsule to erupt through the foil and to the exterior.

First and second layers 21 and 27 of the card are conventionally formed from a single sheet of tag paper or the like, suitably punched out and perforated, adhesively coated (as with polyethylene) on one face, and folded over to sandwich other components of the package. Blister strip 23 is conventionally made of transparent plastic, such as polyvinyl chloride (PVC), from which protrusions 19 are vacuum-formed in the usual manner, spaced at regular intervals so as to protrude through punched openings in the first layer of the card sheet. Before being sandwiched by the card material the blister strip has its protrusions filled with the articles being packaged, whereupon foil strip 25 (usually a laminate with a central paper layer sandwiched by thin metal layers) is secured thereto, as by heat-sealing. Then the layers of card material are juxtaposed, with the blister strip and foil therebetween, and are sealed to one another, usually by application of heat and pressure. The discrete pieces of film backing 29 are applied next or at any subsequent stage as may be desired, being formed of appropriately transparent and adherent material. Such a film of polyester (such as polyethylene terephthalate), for example, is heat sealed to the exposed side of the second layer of card material at cations destined to become flap 13 and multiples thereof. Then perforation lines 15, 16, and 17 are formed in the resulting two-ply card material, and individual cards are cut or stamped therefrom.

The end result is a package that requires sequential severing of perforations between non-connecting edges (as compared with connecting edges of an external corner, for instance), peeling the backing off, and opening an access tab-which necessitates rupturing of the second paper layer of the card along perforated lines-and finally forcing a capsule through the foil layer and an access opening by depression of the opposite blisterlike protrusion. Each of these several steps is sufficiently demanding that a young child can be expected to fail to accomplish one or more of them. Moreover, even if performable individually, they pose the additional problems of being necessarily sequential and sufficiently time-consuming to be discouraging to a child who may be merely playing or who lacks the ability to concentrate long enough on the task to release the contents. A child able to perform all the steps in sequence so as to reach the contents should have sufficient understanding and discretion to avoid ingesting such contents. The safety factor presented by such packaging will tend to protect adults who are too befuddled (as by age, drink, or drugs) to cope with the task of opening the package.

Although a particular embodiment has been shown and described, modifications may be made therein, as by adding, combining, or subdividing parts or steps, or substituting equivalents, while retaining significant advantages and benefits of the invention, which itself is defined in the following claims.
