Field of the Invention This invention relates to packages made from foldable paperboard incorporating a shrinkable plastic film to cover an object placed in a normally scraped region and in which portions of the normally scraped region are used in a functional manner.

2. Description of the Prior Art The medical and pharmaceutical industries are coming to rely more and more upon disposable predosage syringes which must, by necessity, be packaged economically, in large volumes, and packaged in such a manner that they may be easily shipped and stored prior to useage with a minimum of trouble. One way of packaging these items is to place a syringe, sometimes with a disposable needle, along with a filler bottle containing the medicine to be dispensed therefrom. This type of packaging is particularly useful for applications in the field. Since syringes are sometimes made with glass barrels, and since the needle portion of the syringe is susceptible to damage, it is desireable to have a package which protects these areas, incorporates the use of clear plastic films so that the contents may be readily seen, and also one which may be easily stored and stacked in bulk.

SUMMARY OF THE INVENTION A unique and novel design for an apertured card with an aperture appropriate for the shape of a combined syringe and filler bottle placed end-to-end, incorporating the use of a shrink film attached to the back side of the card for holding the syringe and filler bottle in place, and a back panel to cover the aperture and shrink film of the front card. The card has at least one restraining flap extending into the aperture and may be folded up along the side of the syringe, the bottle, or the needle area to provide protection for those areas. End restraining flaps may also be provided in combination with the side flap. The flaps may be formed to extend beyond the height of the syringe and bottle to create a three or more point support for additional cards which then may be stacked on top of the package.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a perspective view of a package containing a syringe and filler bottle and incorporating the present invention;

FIG. 2 is a plan view of a blank adapted to be folded into the package shown in FIG. 1;

FIG. 3 is a plan view of the blank shown in FIG. 2, showing the reverse side thereof and illustrating the application of thermo-plastic film;

FIG. 4 is a side elevational view of two packages such as those shown in FIG. I illustrating the stackable feature of the package.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The package shown in the figures generally as is adapted for use in holding a syringe shown as which has an extendingplunger 16 which has at one end thereof, a flat, round disc I7 against which the thumb pushes to activate the syringe. Also at the top of thebarrel 15 is afinger ledge 18 which is also used in activating the syringe. In the particular package shown, afiller bottle 20 is placed end-to-end with the syringe I5 and the area in which the needle is located, shown generally as 22, may be protected by a plastic sheath which provides asceptic conditions for the needle. Since there is considerable mass on either end of the needle, the combined syringe l5 andbottle 20 must be maintained in a relatively rigid position so that the small end of the syringe I5 and the needle is not damaged.

As can be seen in FIG. 1 as well as FIGS. 2 and 3, thepackage 10 includes afront panel 30 which is substantially rectangular in shape and which has formed therein by die cutting anaperture 35 which extends lengthwise along thefront panel 30 and is generally the length and width necessary to accommodate the syringe andbottle 15 and 20. The ends of theaperture 35 are defined byfold lines 38 and 39 which are used to connectend restraining tabs 40 and 41. These end restraining flaps are folded upwardly to a position normal to the plane of thefirst panel 30 and serve to protect and locate the syringe l5 and bottle 20 in the package. As can be seen in FIG. 4 they are formed in height a distance greater than the maximum dimension of thesyringe 15 orbottle 20 above thefront panel 30.

Along the sides of theaperture 35 are indentedareas 35a and 35b which terminate inhinge lines 50 and 51. The exact size and configuration of theaperture 35 is variable, but in the embodiment shown theextended areas 35a and 35b serve as a base from which extend theside restraining flaps 55 and 56. As can be seen in the drawings, theextended sections 350 and 35b locate the base of theside restraining flaps 55 and 56 close to the sides of the syringe l5 and the needle area 22 so that maximum protection is obtained. In the particular embodiment shown in FIGS. 2 and 3, it can be seen if care is taken in designing the blank for the package I0, then the amount of material which is removed after die cutting can be kept to a minimum by forming theside restraining flaps 55 and 56 so that they are in height a distance equal to the width of theaperture 35 less theextended area 35a or 35b. FIG. I shows how theside restraining flaps 55 and 56 are folded outwardly from the plane of thefirst panel 30 at substantially right angles thereto and the particular embodiment shown the side restrainingflap 55 lies directly adjacent to the finger hold 18 and the syringe IS.

The side and end restraining flaps S5, 56, 40, and 41 are all folded outwardly from the plane of thefirst panel 30, and as can be seen in FIG. 4 they are formed so that they all project an equal distance from the plane of thecard 30, thereby creating a series of support points on which a similar package may be stacked as shown in FIG. 4 where two such packages are positioned one on the other.

As can be seen in FIG. I and FIG. 3, there is a film of thermo-plastic material 60 positioned over the back side of thefirst panel 30 and formed in size sufficient to cover the entire aperture. The package is formed by placing thefirst panel 30 face down on a vacuum mold or other pocket forming apparatus which expands thefilm 60 to create a pocket large enough to accommodate the combination syringe I5 and fillbottle 20. Asecond panel 65 is then placed and sealed to the back side of thefirst panel 30 so that the syringe I5 and fillbottle 20 cannot fall out. The package is then processed through a means for heat shrinking the film about the syringe and bottle which brings thefilm 60 into close contact with all the parts of the package which are exposed The outwardlyfoldable restraining flaps 40. 4!, 55 and 56 typically move outwardly when thefilm 60 is formed into a pocket prior to loading the syringe and bottle. The back panel orsecond panel 65 may be a second sheet of paperboard or it may be hingedly attached as shown along thehinge line 66 in which case it is merely folded into position after the pocket is formed in thefilm 60 and the articles are loaded into the aperture.
