3 Claims. (Cl. 229-27) The present invention relates generally to carton assemblies, and more particularly to carton assemblies having an inner compartment disposed within the outer carton assembly.
The present invention provides carton assemblies which are reinforced at the base of the carton to provide a support for a bottle, tube, or other article in such a way that an accidental opening of the bottom flap of the carton will not permit the contents of the carton to drop out.
In a preferred form of the invention, a carton having two compartments is provided, one inside the other, and one or both of the compartments is provided with a support member on which the base of the article contained in that compartment is received. This support member is independent of the base of the canton itself and provides adequate support for the article even if the bottom of the carton is accidentally opened. This structure is of particular usefulness for packaging articles of different sizes, as for example, two bottles of different heights or a bottle and a tube of different sizes. In packaging articles of this nature, the smaller of the two articles is inserted in the compartment having the aforementioned base support so that when the carton is opened from the top, the tops of the two articles are at the same level, facilitating the removal of each from the carton.
An object of the present invention is to provide an improved carton assembly containing a support for supporting the base of fragile articles contained in the carton, the support being separate from the flaps making up the bottom closure for the carton.
Another object of the invention is to provide a compartmented carton for holding articles of different sizes and in which a base support is provided for one of the articles to prevent injury to the article upon accidental opening of the base of the carton.
A still further object of the invention is to provide carton assemblies which can be readily manufactured from available materials on carton folding machines, which cartons have the aforementioned features.
Another object is the provision of improved blanks for making cartons in accordance with the foregoing objects.
A further description of the present invention will be made in connection with the attached sheets of drawings in which:
Figure 1 is a plan view of a blank used in the formation of a carton according to the present invention;
Figure 2 is a plan view of the blank after its initial folding, illustrating the condition in which the folded blank, may be shipped to a packaging station;
Figure 3 is a cross sectional view taken along the line 3-3 of Figure 2;
Figure 4 is an end view of the folded carton set up with the bottom flaps opened to illustrate the construction of the supporting wall;
Figure 5 is a plan view of a blank for forming another carton in accordance with the present invention; and
Figure6 is a view, in perspective, partially broken away to illustrate the structure formed from the blank shown in Figure 5.
In Figure 1, reference numeral 7 indicates generally a blank which may be composed of paper board or similar carton making material. The blank when set up forms an outer compartment 8 and an inner compartment 9, as shown in Figure 4. For these purposes, the blank is formed into a series of contiguous panels including a first panel 11, which ultimately forms the rear panel of the outer compartment, a second panel 12, which forms one of the side panels for the outer compartment, a third panel 13, which forms the front panel of the completed outer compartment, and a fourth panel 14, which forms another side panel for the completed carton.
As indicated in Figure 1, the first panel 11 is divided from the second panel 12 by means of a score line 16, the second panel 12 from the third panel 13 by means of a score line 17, and the third panel 13 from the fourth panel 14 by a score line 18.
The first panel 11, at its upper and lower ends, is scored with horizontally extending score lines 19 and 21, respectively, and outwardly spaced score lines 22 and 23 provide a top and a bottom 24 and 26 for the completed carton. A flap 27 extends from the top 24 which flap may be inserted behind the front panel 13, the folding of the flap being facilitated by the provision of a pair of slits 28 extending along the score line 22. Similarly, the bottom 26 is provided with a flap 29 which may be received behind the front panel 13, and the bottom is also provided with slits 31 to facilitate folding of the flap 29.
The first panel 11, at its extreme marginal edge, may be coated along a limited area 32 with an adhesive, for a purpose which will hereafter become apparent.
The second and fourth panels 12 and 14, which be come sides of the outer compartment 8, each have tuck flaps 33 and 34 at the top end and tuck flaps 36 and 37 at the bottom end. These fiaps cooperate with the top 24 and bottom 26 of the completed carton in the conventional manner.
Adjoining the fourth panel 14 is a series of three contiguous panels, which define the inner compartment when the carton is set up, including a first inner compartment panel 33, which is separated from the panel 14 along a score line 39, a second inner compartment panel 41, which is separated from the panel 38 by a score line 42, and a third inner compartment panel 43, separated from the panel 41 along a score line 44. The panels 38, 41, and 43 provide the rear, side and a portion of the front panel of the inner compartment 9, respectively, when the carton is folded in the manner to be described. Panel 14 is common to the outer compartment '8 and inner compartment 9, this panel providing a side wall for each compartment.
A base support for articles enclosed within the inner compartment 8 of the completed carton is provided by an extension 46 which is supported from the blank only along a score line 47, the latter being a longitudinal extension of the score line 44 between inner compartment panels 41 and 43,-thereby carrying the extension on the third inner compartment panel 43. The score line 47 should be more resistant to folding than the score line 44. This can be done by varying the depths of the scores or other equivalent ways. When this is done, the extension 46 more readily positions itself when the carton is set up.
As shown in Figure 1, the extension 46 is provided by foreshortening the second inner compartment panel 41 a predetermined amount by cutting along line 49 into the first inner compartment panel 38. The length of the cut is equivalent to the diagonal distance across the bottom of the inner compartment 9. The other side of the extension 46 is provided by cutting the panel 38 out! wardly along line 51. At the point of juncture of cut lines 49 and 51, designated 52 in the drawings, the extension is rounded so as to facilitate positioning of the extension 46 when the box is set up.
It will be seen that as the blank is folded into a compartmented structure, when the. panels 38, 41, and 43 defining the inner compartment 9, the extension 46 is caused to extend diagonally across the inner compartment thus formed. This structure is best illustrated in Figure 4 of the drawings.
The carton may be assembled from the blank shown in Figure 1 in the following manner. The series of three inner compartment panels 38, 41, and 43 may be folded over from right to left, as viewed in Figure 1, so that the outer face of panel 43 is in contact with an area on y the third panel 13, designated at 54 on the drawings,
where an adhesive strip may be applied to secure the panel 43 to the inner surface of the panel 13.v When this folding takes place, the extension 46 automatically locates itself diagonally across the compartment 56 formed by the folding operation. The folding may then be resumed to form the outer compartment 8 by folding the panels 11 and 12 from left to right, as viewed in Figure l, and then securing the inner surface of the panel 11 (as shown in Figure l) to the outer surface of panel 38 (as shown in Figure 4) along the adhesive strip 32.
The panel, after folding and gluing, is readily collapsible into a flattened unit which can be packaged and shipped to the place where the completed carton is to be filled with bottles or other merchandise to be packaged. The collapsed condition of the carton is illustrated in Figures 2 and 3 of the drawings. As evidenced from an inspection of Figure 3, the extension 46, in collapsed condition, is disposed between the panel 11 and the panel 14 so that the presence of the extension 46 does not contribute materially to the bulk of the carton in its collapsed condition. Furthermore, since in collapsed condition the extension 46 overlies the-panel 11, extension is forced diagonally across the inner compartment when it is set up.
A modified and simplified form of the invention is illustrated in Figures and 6 of the drawings. In Figure 5 there is illustrated a blank 60composed of six contiguous panels. The first of these panels, labeled 61, is of considerably less height than the remaining panels and, in the folded condition of the carton, provides a support for the fragile article to be packaged in the carton. This panel is of greater width than the other panels and its width is equivalent to the diagonal distance across the bottom of the carton. In case the carton is intended for use with a tube, the panel 61 may be notched, as indicated at 62, to provide a seat for the base of the tube and prevent its rotation within the carton.
The panel 61 is separated along a score line 63 from a second panel 64 which forms one of the rear walls of the completed carton. The panel 64 is adjacent to a third panel 66 which becomes a side wall, and is separated therefrom by a score line 67. The panel 66 at its oppositeends is provided with a pair of tuck flaps 68 1 1 '1 and 69 separated from the panel 66 along transversely extending core. 1ines71 and 72-.
The fourth panel 73 of the blank provides the front wall for the completed carton, and this panel is separated from the third panel 66 by a score line 74. The fifth panel 76, which forms a second sidewall, adjoins the front panel 73 and is separated from that panel by a score line 77. The panel 76 also has a pair of opposed tuck flaps 78 and 79 defined by a pair of transversely extending score lines 81 and 82. These flaps 78 and 79 cooperate with the flaps 68 and 69 to provide end closures for the completed carton as best seen in Figure 6 of the drawings.
The sixth panel 83 extends from the fifth panel 76 along a score line 84. Transvctsely extending score lines 86 and 87 define a top 88' and a base 89 for the completed a t n an uck flaps an 9 ar attached, ereto o close the ca ton in the sual ma er- T tuck flap 90 is separated from the top 88 along a score line 92 and slits 93, which facilitate folding, while the flap 91 is separated from the base 89 along a score line 94 and slits 96.
In folding the carton, the panel 61 is folded inwardly of the blank and the panels are folded in the usual a n rto Pr i e a re aa ula enc u e ng a d9 ble thickness rear panel provided by overlying panels 64 a d. 3- UPQn f d n th Pa 1 will l f diagonally acoss the base of the carton, as shown in Fig: e o pr vide a bas sur g nde d n f e ba of he c r n- Wi h his rr n e n e ta openn of t fl p w not r p t e n i e ou o the cart na s mb ras it i ad a atelv supported in pos in al n h top s rfa of the pan l 6 The panels are conveniently secured together by apply: ins adh i b ween the s rfa s o Pa l 64 n 3,
