FIG.4

July 2, 1963 H. PFoHL 3,095,966

PACKAGE Filed Dec. 16, 1960 2 Sheets-Sheet 2 lB l'aB I3 United States Patent O 3,095,966 PACKAGE Louis Henry Pfohl, Forest Hills, NX., assign-or to Design Center, Inc., Long Island City, NX., a corporation of New York Filed Dec. 16, 1960, Ser. No. 76,206 4 Claims. (Cl. Zilli-45.31)

The present invention relates to packaging, and more particularly to the packaging of merchandise for display and sale Iand to a method for producing such packages.

In packaging merchandise for display a-nd sale, it is desirable .in many instances to so construct the pack-age that the package and merchandise will stand up-right on a counter or `other horizontal display surface. It is also desirable that such package be of the blister type, in which -a major portion of the package 4is formed from a transparent sheet of plastic. Such blisters are ldesirably prepared by a thermoforming procedure in which a web of a suitable transparent plastic, eg., oriented styrene, is heated and then shaped by means of :dies into the desired configuration. By thermoforming, blister packages which conform -generally in shape to the goods to be packaged therein can conveniently be made. -A highly satisfactory thermoforming machine is shown in United States Patent 2,961,137 to Menkel, which issued November 22, 1960. Another suitable machine is shown in United States Patent 2,522,956 to Middleton, which issued September 19, 1950.

The principal object of the invention ihas been the provision of `a blister package which has a structure adapted to permit the articles of merchandise packaged therein, whether they be bottles, tubes or other shaped objects, to stand upright on a counter.

Another object of the invention has been the provision of such a package which can be produced and assembled economically.

Still another object of the invention .has been to provide =a plastic blister which cooperates with a simple paperboard structure to Iform a-n attractive upright display package.

A feature of the invention has been to provide a plastic blister structure having an open back and 'an open base and in ywhich the back and base are provided with peripheral flanges at right angles.

A further object of the invention has been to provide a method for producing such blisters by a thermoforming process.

Other and further objects, features and `advantages of the invention will appear more fully from the following description taken in connection with the appended drawings, in which:

FIG. 1 is .a front elevational view of a completed package in accordance with the invention;

FIG. 2 is a longitudinal sectional view taken along the line 2 2 of FIG. l;

FIG. 3 is a horizontal sectional view taken along the line 3 3 of FIG. 1;

FG. 4 is a front elevational view of the plastic blister of the package of FIG. l;

FIG. 5 is ,a front elevational View of a modified form of package rconstruction in accordance with the invention;

FIG. 6 is a longitudinal sectional view taken along the Aline 6-6 of FIG. 5;

FIG. 7 is a front elevational view of a blister blank at an intermediate stage of blister -formation; yand FIG. 8 is a sectional view taken along the line 8-8 of FIG. 7.

Referring now to the drawings, and more particularly to FIGS. l-4, the package of the invention comprises a plastic blister designated generally by the reference 3,095,366 Patented July 2, 1963 numeral 10 and a paperboard stand designated generally by the reference numeral 11.

The plastic blister 10, which is preferably produced by a thermoiorming process from ,a web oi transparent plastic such as polarized extended styrene, comprises `a hollow body portion 12 having ian open back and an open base. A horizontally extending ilange 13 is provided around the periphery of the open 'base of body portion 12. -A vertcally extending iiange 14 is provided around the periphery of the open back of .body portion 12. rBhe planes of the ila-nges 13 and 14 extend at right angles to each other and the iianges join along the lines 15 Iand 16 at the juncture of the periphery of the open base and the periphery of the open back. The body portion 12 land the flanges 13 yand 14 `are ian integral structure produced from -a web of thermoplastic material. The top of the body portion 12 is closed, as shown at 17.

The body portion 12 may be shaped to conform generally to the shape of the merchandise to 'be packaged, shown here as two bottles 18 and 19. For holding the bottles y11? and 19 in proper vertical position, a recess or lfdirnp-le 20 is provided in the front of the body portion 12. The recess 20 eiiectively divides the body portion into two compartments.

The paperboard stand 11 may b-e formed from la single sheet of paperboard folded along la line 21 to provide a vertical back section 22 and a vertical .front section 23. The portion of the paperboard containing the back section 22 is folded along a line 24 to provide .a horizontal Ibottom section 25. The portion of the paperboard containing the 'front section 23 is folded along a line 26 to provide a horizontal section 27 which overlies the bottorn section 25. The section 27 is provided with an aperture 2S corresponding in size and shape to the open base of the blister body portion 12. The front section 23 is provided with a similar aperture 29 corresponding in size Aand shape to the open back of the blister body portion 12.

The apertures 28 and 29 join along the line 26 to provide `a composite aperture i-n the front paperboard sheet (23 and 27) which has a periphery substantially the same size and shape as the composite periphery of the open back and open base of the blister body portion 12. The horizontal frange 13 lies between the paperboard sections 2S lamid 27, While the ilange 14 lies between the paperboard sections 22 and 23.

After assembly, the paperboard sections 25 and 27 rnay be joined together, as by the use of one or more staples or by the use of ya suitable adhesive, yielding a unitary structure in which the -f-ront and back paperboard sections 23 'and 22 retain the flange 14 and the bottom paperboard sections 25 and 27 retain the ange 13. It is desirable that the 'front and Iback paperboard sections be joined by staples or adhesive. Suitable staple locations =are indicated at 30, 31 and 32.

Suitable advertising matter rnay be printed on the iront race of the paper-board section 23, as indicated at 33, and also on the upper surface of the paper-board section 27. The paperboard used yfor the stand 11 need not be sufficiently rigid as to be able to stand upright since the blister 10 `aior-ds added rigidity to the assembled structure, thus maintaining the package in an upright position.

rThe package as described above is a preferred form of the invention `and the composite structure affords 'numerous advantages. However, the blister 10 may be used i-n Ia simpler package structure. Such a structure is shown in FIGS. 5 and 6 Iand involves only the paperboard sections 22 and 25 and the blister 10. The flanges 13 and 14 are afxed to the sections 25 and 22, respectively, by suitable means such as an adhesive as shown -at 11 in FIG. 5. In .this simpler form of construction, the

Yflanges 14.

rigidity afforded by the integral construction of the llanges 13 and 14 affords considerable stability.

In the process of forming the blister of the invention, a web of plastic material, eg., oriented styrene, is advanced step by step through a thermoforming operation.

VIn this operation lthe web is seized adjacent each edge thereof, is advanced to a heating station where the plastic material is heated to a softened condition and is then advanced to a forming station. In the forming station the softened web is contacted by dies which produce two lblister blanks in axial alignment and with open bases facing each other but separated by a short length of web. Actually, a series of Vsuch pairs of axially aligned blister blanks may be formed simultaneously across the web Width.

A pair of axially aligned Ablister blanks is illustrated in FIGS. 7 and 8. It will be observed that the flanges 13 which extend around the open bases of the blanks are joined by a short section of web 13. After the 4blanks have been formed they are die ycut along the planes 13A and 13B to produce the individual blister as shown in FIGS. 1-4 and 5-6. This die cutting along the planes 13A and 13B separates the two blister blanks and eliminates the web section 13. Since the flanges 13 and 14 are integral, the web section 13 also extends between the flanges 14 of each blank and is :cut out of the web as part of the operation of cutting along the planes 13A and 13B. The pair of :blister blanks is cut out of the plastic web from which the blister blanks are formed by a die cutting operation around the periphery of the The cutting out of the blisters from the web is preferably performed before the cutting along the planes 13A and 13B, but may be performed at the same `time or subsequently.

While the invention has `been described in connection with specic embodiments thereof and in specicuses, various modilcations thereof will o-ccur to those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims.
