C. E. COTTRILL DOUBLE-WALLED CONTAINER AND METHOD FOR MAKING March 29, 1960 Filed Aug. 29, 1956 INVENTOR Cfiat'les E. Cafiz'ill ATTORNEYS United States Patent 6 DOUBLE-WALLED CONTAINER AND METHOD FOR MAKING SAME Application August 29, 1956, Serial No. 606,906 1 tllaim. (Cl. 229-51) This invention relates to both method and means for forming a container, and more specifically, this invention pertains to a method and means for constructing a double-walled carton.

It is a well-established fact that manufacturers of merchandise of the type which lends itself Well to carton packaging frequently desire to display their respective products in cartons suitably embellished to salute a holiday or other special occasion. Again, such merchandise is frequently advertised as being gift wrapped which, of course, is a further sales feature to induce the public to purchase the attractively packaged merchandise.

To protect such packaged merchandise it is customary to surround the embellished carton with a protecting sleeve which is generally telescoped over the packaged product. This, of course, prevents the embellished carton from becoming soiled when carried by the purchaser, but since most of the protective sleeves are open-ended, it is not infrequent that the carton inadvertently or accidentally slides out of either end of the sleeve, an undesirable feature which frequently results in damage to the merchandise.

One of the primary objects of this invention is to provide an embellished carton for material to be packaged, the carton having integrally formed therewith a wraparound cover or device to prevent damage to or the soiling of the embellished sides of a carton, the device being integrally formed with the carton and being provided with means whereby the cover may be quickly opened and detached from the carton.

A further object of this invention is to provide a wraparound cover for a carton which is integrally formed therewith, with means whereby the carton and the cover are prevented from inadvertent movement relative to each other. This feature of the invention, of course, prevents the inadvertent or accidental separation of the carton with respect to the cover, thereby serving to insure against damage to the merchandise.

A further object of this invention is to provide an especially embellished carton for a liquor decanter with an integrally formed Wrap-around cover to protect the embellished carton from being soiled and at the same time to provide means whereby the user may imprint, or otherwise display on the cover the normally applied and day-to-day advertising features or other indicia relating to the packaged product.

A still further object of this invention is to provide a carton of the type described with an integrally formed wrap-around cover forming, in effect, a double-walled carton whereby additional protection is afforded to the merchandise against damage caused by externally applied forces.

This invention contemplates as a still further object the provision of a carton having a wrap-around cover together with tear means to open the cover as well as tear means for separating the carton from the cover.

A still further object of this invention is to provide a double-walled container of the type referred to above.

which is non-complex in construction and assembly, in-

expensive to manufacture, and durable in use.

Other and further objects and advantages of the present invention will become more evident from a consideration of the following specification when read in conjunction with the annexed drawings, in which:

Referring now more specifically to the drawing, reference numeral 10 designates, in general, a substantially hollow double-walled carton formed from a single blank 12 and constructed in accordance with the teachings of this invention. The blank 12 is formed from any substantially stiff but foldable material such as, for example, cardboard.

Referring to the blank illustrated in Fig. 1, reference numeral 14 indicates an elongated substantially rectangua lar tongue having an adhesive 16 applied thereto. The tongue 14 is disposed adjacent one of the longitudinally extending edges of an inner carton side wall '18 having a substantially rectangular configuration, and is defined therefrom by means of the scored fold line 20.

The side wall 18 is provided at each of its ends with an elongated substantially rectangular top and bottom closure tab 22 and 24, respectively, the tabs 22, 24 projecting longitudinally beyond the score of fold lines 26, 28 adjacent the top and bottom ends of the side wall 18.

As viewed in Fig. 1,, the underside of the tab 24 has a triangular area 32 disposed adjacent the score line 28 and proximate its inner side edge 34, the area being coated with an adhesive 36. The tab 24 has a slightly smaller lateral width than the width of the side wall 18, and a diagonal score or fold line 38 extends from the corner formed at the junction of the inner edge 34 with the score line 28 to a point proximate the center of the outer end edge of the tab 24.

The second main side wall of the carton is indicated by reference numeral 40 and has substantially the same longitudinal and lateral dimensions as the side wallf18. The side wall 40 is provided with top and bottom closure tabs 42 and 44, respectively, the tabs 42, 44 projecting longitudinally away from the opposed ends of the side wall 40 and being defined therefrom by the score or fold lines 46, 48. The tab 42 is separated from the tab 22 along the line 50 and has a substantially trapezoidal configuration due to the diagonal outer edge 52.

The bottom tab 44 has an inner edge 56 which extends substantially parallel to the inner edge 34 of the tab 24 and is spaced therefrom to form a gap 58 therebetween. This gap also serves to facilitate the assembly of the carton 10.

The outer side edge 60 extends at an acute angle between one end of the score 48 to the free outer end of the tab 44 giving rise to a second trapezoidal configura-- tion. To serve a function to be described, and as viewed in Fig. 1, a substantially triangular area 62 on the underside of the tab 44 is covered with an adhesive 64.

Score or fold lines 66, 68 define the side wall 40 from the oppositely disposed, longitudinally extending main side walls 18 and 70, respectively.

The main side wall 70 has the same dimensions as the Patented Mar. 29, 1960 main sidewalls 1'8 and 40 and is provided with a longi- I tudinal-ly projecting bottom tab 72 having a substantially rectangular configuration.

The underside of the tab 72, as viewed in Fig. 1 is provided with atriangular area 74 adjacent its side edge 76, and the triangular area 74 is covered with an adhesive 78. As is seen in Fig. l, the tab 72 projects out- Wardly away from the score line 81 substantially the same distance the tab 44 projects beyond its associated score line 48.

Score 'or fold line 82 separates the fourth main side wall 38 from the adjacent third main side wall 70. The main side wall 88'is identically proportioned with respect to the other main side walls 18, 411 and 70, and is provided with top and bottom tabs 90 and 92, respectively. The tabs 90, 92 project longitudinally away from their respective adjacent score or fold lines 94, 96. Each of the tabs 90, 9-2 is provided with an edge '98, 100, respectively, inclined at an acute angle with respect to their associated score lines 94, 96 whereby the tabs 90, 92 are substantially trapezoidal in configuration.

The tab 92 has a triangular area 104 coated with an adhesive 106, and has an inner side edge S disposed in "spaced, parallel and confronting relation with respect t'o'the edge 76 of the tab 72. The space therebetween forms a gap 110 to facilitate the assembly of the carton 10. Reference numeral 111 indicates adhesive which extends along the marginal side of the side wall 88 adjacent the line of perforations 112.

The blank as described thus far is conventional and well known in the art. The novelty of .the present in vention comprises the provision of four elongated substantially're' ctangular panels 114, 116, 118 and 120 which form the wrap-around cover or the second side walls of the carton 10. As viewed in Fig. 1, the panels 114 and 120 are identical inconiiguration but reversed with respect to each other. Panels 116, 118' have identical dimensions. 'The panel 114 is provided with a line of perforations 1'22which extendlparallel to but spaced from the perforated line 112 to form a tear strip 113, and the underside of the tear strip 113 bounded by the perforated lines 112, 122 is adhesively coated at 126.

The upper end of the side wall 88' is cut out at 123 adjacent theperforated line 112, and the upper corner ofthe panel114 is notched at 1311 adjacent the perforatedline 122 to form an extension 132 therebetween. Scoreor fold lines 136, 138 and 149 serve to define the panels 114, 116, 118 and 120. As seen in Fig. l, the panel 120 has an outer marginal end portion comprising a second tear strip 142 covered with an adhesive 144, and adjacent its outer marginal end the panel is provided with an elongated line of perforations 146. Thepanel 120' is also notched at 143 to form an extension 150 at the upper and outermost corner thereof.

To assemble the double-walled carton 12, the lip 14 is bent on the score line 20 away from the plane of the drawings and vertically with respect to the side wall 13. The side wall 18' is now bent perpendicular to the side wall 40 along score line 66 and in a direction away from the plane-of .the drawings. The side walls 18 and 40 are now turned about the score line 68' until the side wall 18 islparallel to the side wall 70. Side walls 18,40 and 70 are now turned around the score line 82 until the side walls 40 and 83 are substantially parallel and with the .adhesively coated lip engaged against the outermarginaledge-of the side wall 88 coated with the adhesive 111 at whichpoint they are bonded together.

1 -.The bottom of the carton 10 is now formed by bend ingthe tab 24 inwardly along the score line 38' and bending the triangular corner so formed outwardly away from thecarton.

The flap 72 is. folded about .the score line 8i1perpendicular to the side-walls..18,'4t), 70 and 88. The triangular corners of the tabs :44. and 92 are now bent on their respective score lines 62 and 105, and the adhesivecoated area 64 of tab 44 is brought into engage.- ment with and is bonded to the adhesive 36 carried on the tab 24. In a like manner tab 92 is moved to cause its adhesive surface to engage and bond with the adhesive 78 of the tab 72.

The panel 114 is now folded over the side wall 18 along the score line 112, and in succession, the panel 116 is folded on its score line 136 to cover the side wall 40; panel 118 is folded across the side wall 70 about the score line 133; and the panel 120 is folded on score line 140 to cover the side wall 88. The end portion or tear strip 142 is now bent along the score line 146 to cause the same to come into face-to-face engagement with the tear strip 113 having the adhesive coating 126 to which the tear strip 142 is now bonded.

The material to be packaged is now inserted through the open upper end of the carton 10 after which the tabs 42 and 99 are bent inwardly about the scoreilines 46 and 94, after which the closure tab 22 is folded thereacross in the manner shown. The cutouts or slots 31? comprise means for expediting the opening of :the canon To remove the outer panels and to detach the panelsfrom the cartonflthe user grasps the overlapped extensions 132 and 159 of the tear strips 113 and 142 and pulls downwardly thereon. This action simultaneously frees the panel 114 from the panel 121) and separates the panel 114 from the adjacent edge of the side wall 88 along-the perforated line 112. The carton may now be easily removed from within the confines of the panels. It is now seen that the double walled carton 10 has been integrallyconstructed from the blank 12. As has been previously stated, the panels 114, 116, 118 and 121 prevent the ornate, embossed or imprinted side walls 13, 4t '79 and $8 from becoming soiled by the user's hand or from other sources. It will also be recognized that the panels may also bear conventional advertising indicia normally used'by the manufacturers and also serves to reinforce the side walls of the carton and thereby prevents damage to the carton or the contents thereof. Having described one embodiment of this invention, his to be understood that the same is offered only by way of example, and that the invention is to be limited only by'the scope of the appended claim.
