FIG. 5 %a% SHRINK FILM PACKAGE AND STABILIZING DEVICE THEREFOR When a shrink film type of overwrap is snugly secured about a group of irregularly shaped articles such as bottles, there is a tendency in some instances for one or more bottles to shift about due to pressure applied by the relatively tight shrink film overwrap. Furthermore sharp edges such as are characteristic of the caps of bottles and the chimes of cans tend to impart substantial stress to the overwrap and thus tend to weaken the entire package. Where lifting panels are disposed within the wrapper and atop one or more of the packaged articles, there is a tendency for such panels and the adjacent portions of the overwrap to bow and hence to impart an element of instability which substantially impairs the security of the package.

According to this invention a stabilizing device is provided which incorporates a main panel arranged in overlying relationship with respect to the tops of a group of packaged articles and a pair of auxiliary panels having apertures therein corresponding to the articles are folded underneath the main panel into an angular relationship therewith to cause the top portions of the articles to be received within the associated apertures. If desired, an end panel may be foldably joined to each end of the main panel and web structure may be used to interconnect the ends of the end panels and the adjacent ends of the auxiliary panels and an overwrap is disposed about the articles and the stabilizing device. Thus the auxiliary panels and if used the end panels incorporate a substantial measure of stability and resistance to bowing when the package is lifted by gripping the main panel either by way of finger gripping apertures or otherwise. Furthermore, the edges of the main panel tend to protect the overwrap disposed about the package against rupture by preventing engagement with the sharp edges of the caps of the articles.

For a better understanding of the invention reference may be had to the following detailed description taken in conjunction with the accompanying drawings in which:

FIG. 1 is a perspective view of a package formed according to the invention;

FIG. 2 is a plan view of a blank from which the stabilizing device shown in FIG. 1 is formed; and in which FIG. 3 is a sectional view of the package shown in FIG. 1 as taken along the line designated 3-3 in FIG. 1.

In the drawings the numeral 1 designates the main panel of the stabilizing device. A pair of finger-gripping apertures 2 and 3 are formed in main panel 1 and a pair of

auxiliary panels

4 and 5 are foldably joined to main panel 1 along its side edges 6 and 7 respectively.

For the purpose of enveloping at least a portion of the top of each of the packaged articles such as the bottles B, a plurality of apertures 7, 9 and 10 are formed within auxiliary panel 4 and

similar apertures

11, 12 and 13 are formed within auxiliary panel 5.

For providing lateral stability to the main panel 1, a pair of

end panels

14 and 15 are foldably joined respectively to the ends of main panel 1 along fold lines 16 and 17. Preferably these

end panels

14 and 15 are held in a generally perpendicular relationship to the main panel 1 when the package is assembled as shown in FIG. 1. Toward this end,

anchoring panels

18 and 19 are foldably joined to the end edges of

auxiliary panels

4 and 5 respectively along

fold lines

20 and 21.

Web panels

22 and 23 are foldably joined to anchoring

panels

18 and 19 along

fold lines

24 and 25.

Web panels

22 and 23 are foldably joined to anchoring

panels

18 and 19 along

fold lines

24 and 25.

Web panels

22 and 23 are foldably joined to end panel 14 along

fold lines

26 and 27 respectively.

The end panel 15 is identical to end panel 14 and is held in a vertical position by

anchoring panels

28, 29 having fold line connections with. the

auxiliary panels

4 and 5 as indicated at 30 and 31.

Web panels

32 and 33 are foldably joined along fold lines 34 and 35 to anchoring

panels

28 and 29 respectively and to end panel 15 along

fold lines

36 and 37.

Once the articles such as B are assembled in rectilinear relation with their vertical axes parallel as shown in FIG. 1, the stabilizing device is disposed atop the bottles after the

auxiliary panels

4 and 5 are folded downwardly and inwardly to positions of angular relationship underneath main panel 1. This folding operation causes the

auxiliary panels

4 and 5 to occupy positions of acute angular relationship with respect to main panel 1 as is best shown in FIG. 3. When so folded the top portions of the articles 8" are partially enveloped within apertures in the auxiliary panels. For example, the cap C1 of article B1 is partially enveloped within the aperture 10 while the cap C2 is partially enveloped within aperture 13 as is apparent from FIG. 3. In like fashion the caps of the remaining; bottles are partially enveloped within the apertures 8, 9, 11 and 12 as is obvious from the drawing.

In order to improve stability of the package during carrying, the edge such as 38 of aperture 10 underlies and grips the lower edge 39 of cap Cl. In like fashion the corresponding edges of all the other apertures underlie the lower edges of the caps of the remaining bottles and thus greatly enhance stability of the package.

Bottle stability is enhanced by the

end panels

14 and 15. As shown in FIG. 1, end panel 15 is disposed in perpendicular relationship with respect to the main panel 1 and is held in this position due to the fact that the

anchoring panels

28 and 29 are disposed in flat face contacting relationship with the inner surfaces of

auxiliary panels

4 and 5 respectively. This action by virtue of the

web panels

32 and 33 secures the end panel 15 in a vertical position as shown in FIG. 1. In like fashion end panel 14 is maintained in a vertical position. Obviously the end panels tend to enhance stability of the package laterally and thus tend to prevent bowing about a longitudinal axis when the package is picked up via the finger-gripping apertures 2 and 3.

Longitudinal stability of the package is substantially enhanced due to the

auxiliary panels

4 and 5 which, as is obvious, substantially strengthen the main panel 1 against bowing about a transverse axis due to the fact that a substantial vertical component of

auxiliary panels

4 and 5 is effective to brace the panel as is obvious particularly from FIG. 3.

After the package is assembled as is shown with the articles B and the stabilizing device in the positions depicted, an overwrap W of suitable material such as shrink film is secured about both the articles and the stabilizing device with apertures formed therein in coincidence with apertures 2 and 3. Since this wrapper normally is maintained in tension so as to hold the articles in a secure and snug relationship with respect to each other and since the tension of the wrapper may tend to rupture the shrinkfilm especially about the packaged corners and in areas where the caps of the bottles may come into sharp contact with the wrapper, it is apparent that the stabilizing device protects the film against such undue contact and stress and in this manner tends to enhance the security and stability of the package.

Instead of using apertures as shown in FIG. 2 and identified by the numerals 8-13, it is within the contemplation of the invention to form U-shaped cuts in

panels

4 and 5 and arranged with the prongs of the slits emanating from fold lines 6 and 7 so that a tab integral with panel 1 would be formed in overlying relation to each bottle cap.
