Abstract
Description
- This invention pertains to carrier stock for machine application to substantially identical cans or other containers. This invention pertains, more particularly, to carrier stock for machine application to the side walls of such containers.
- Typically, carrier stock with individual container-receiving apertures for machine application to substantially identical containers is formed, as by die-cutting, from a single sheet of resilient polymeric material, such as low density polyethylene.
- An example of such stock for machine application to substantially identical containers in three longitudinal rows of indeterminate length is disclosed in US-A-4,018,331. As disclosed therein, such stock may be transversely severed, after it has been applied to such containers, to produce packages with three containers, six containers, or other multiples of three containers. A suitable machine for applying such stock is disclosed in US-A-3, 959,949.
- Typically, each such container has a chime formed on its upper end, or on each of its ends. In machine application of carrier stock to such containers, it is conventional to apply such stock to the upper ends of the containers, in such manner that edges of band segments of the stock bear upwardly against the chimes when the individual carriers severed from the stock are lifted via finger apertures formed in the stock.
- However, it has been suggested, e.g. in US-A-4,018,331 that such stock may be alternatively applied to other portions of such containers, such as lower end portions of such containers. It would be particularly desirable to apply such stock to the side walls of such containers.
- As disclosed in a co-pending European patent application no.          filed simultaneously herewith, under Attorneys Reference 80/4013/02 and claiming priority from USSN 519,860 a machine has been developed for applying such stock to the side walls of such containers.
- The machine disclosed in the co-pending application noted above employs two camming plates, which have edge contact with the stock as the stock is moved through the machine, to cam the stock downwardly along the side walls of the containers. Considerable friction is created between the plate edges and the moving stock. Such friction tends to cause necking down or breaking at diagonal band segments near the outer edges of carrier stock according to prior designs.
- A need has been created, to which this invention is addressed, for carrier stock that can be effectively applied to the side walls of such containers, as by the machine disclosed in the co-pending application noted above, with minimal risk of necking down or breaking of diagonal band segments near the outer edges of such stock.
- According to this invention a carrier stock for machine application to side walls of substantially identical containers, the stock being formed from a single sheet of resilient polymeric material and being severable to form individual carriers with separate apertures in rectangular arrays with longitudinal rows and transverse ranks to receive the individual containers, the stock having two opposite edges, the stock being formed with integrally joined band segments defining the separate apertures, the segments including outer segments defining the opposite edges of the stock, cross segments extending transversely, and diagonal segments, each diagonal segment having a first end where such diagonal segment is joined to one of the cross segments and a second end where such diagonal segment is joined to three more of the other diagonal segments at a junction,
   is characterised in that:
   each junction is generally X-shaped when the stock is unstressed and is defined by two such diagonal segments constituting a first pair and diverging from such junction toward the nearer edge of the stock and by two such diagonal segments constituting a second pair and diverging from such junction toward the other edge of the stock, and
   in that at least one diagonal segment of the first pair extending from at least one such junction has a progressively changing width when the stock is unstressed with its second end wider than its first end. - This stock is designed particularly but not exclusively for machine application to the side walls of such containers. Notably, such stock is formed with specific band segments having progressively changing widths to minimize necking down or breaking of such specific segments during application.
- The carrier stock provided by this invention is severable to form individual carriers with separate apertures to receive the individual containers when the stock is machine-applied to the side walls of such containers. The separate apertures are in rectangular arrays with longitudinal rows, three rows being preferred, and transverse ranks. Such stock has two opposite edges, one or both of which may be optionally provided with an integral handle for each individual carrier.
- Preferably, if the separate apertures are in three longitudinal rows, each diagonal segment of the second pair at each junction has a substantially uniform width when the carrier stock is unstressed. It is preferred, moreover, that each diagonal segment of the first pair at each junction has curved edges when such stock is unstressed.
- Carrier stock according to this invention can be effectively applied to the side walls of substantially identical containers, as by the machine disclosed in the co-pending application noted above, with minimal risk of necking down or breaking at the diagonal segments of constituting the first pair extending from each junction.
- Particular embodiments of carrier stock and packaging with it will now be described with reference to the accompanying drawings; in which:-
- Figure 1 is a perspective view of a package comprising six identical containers and a carrier;
- Figure 2 is a plan of carrier stock;
- Figure 3 is an enlarged detail taken from Figure 2 to show certain band segments with characteristic shapes contemplated by this invention;
- Figure 4 is a plan of an alternate embodiment of carrier stock; and,
- Figure 5 is a partly broken away perspective view showing where certain elements of a machine contact carrier stock.
- As shown in Figures 1 through 3,
carrier stock 10 for machine application to substantiallyidentical containers 12 constitutes a preferred embodiment of this invention.Such stock 10 is formed withseparate apertures 14 to receive theindividual containers 12. Thecarrier stock 10 is severable, along transverse lines to be later described, to formindividual carriers 20 that are substantially identical. - As shown in Figure 1, the
containers 12 are beverage cans of a type used commonly for beer, soft drinks, and other beverages. Also, eachcontainer 12 has a chime 16 at one end, which is provided with a pull tab 18. This invention is not limited, however, to usage with such cans but is useful with cans, bottles, and other containers of various types. - In Figure 1, a package is shown, which comprises six
such containers 12 and onesuch carrier 20, as severed fromsuch stock 10. Onesuch carrier 20 is shown fully in Figure 2, which also shows fragmentary portions of thenext carrier 20. Eachcarrier 20 is shown in an unstressed condition in Figure 2. - The
carrier stock 10 is formed in an indeterminate length, as by die-cutting, from a single sheet of resilient polymeric material. A preferred material is low density polyethylene. A preferred thickness forsuch stock 10 in an unstressed condition, if low density polyethylene is used, is about 14 mils (0.36mm). - The
carrier stock 10 is formed, for eachindividual carrier 20, with integrally joined band segments defining sixseparate apertures 14. As shown in Figure 2, such apertures are in a rectangular array with longitudinal rows and transverse ranks, namely three longitudinal rows and two transverse ranks for eachindividual carrier 20. - The
carrier stock 10 is applied to the side walls of therespective containers 12 away from the chime 16 of eachcontainer 12. Thestock 10 is designed to be effectively applied by the machine disclosed in the co-pending application noted above. - As shown in Figure 5, the machine comprises a conveyer C, which is used to convey an indeterminate number of the
containers 12 in a rectangular array with three longitudinal rows and an indeterminate number of transverse ranks, three transverse ranks being shown. Moreover, the machine comprises two camming plates P fixed in parallel relation to each other, and in edge contact with thecarrier stock 10 as thestock 10 is moved through the machine. Further details of the machine may be found by reference to the co-pending application noted above. - Because the
carrier stock 10 is applied to the side walls of therespective containers 12, thecarrier stock 10 requires less material and can be thus made of thinner material with band segments of narrower width, as compared to carrier stock (not shown) applied directly beneath chimes like the chimes 16, which are abutted by edges of such stock. - The band segments include relatively narrow outer and diagonal segments and relatively wide cross segments. The outer segments include
outer segments 22 extending along what may be hereinafter called the handle edge ofsuch stock 10 andouter segments 24 extending along the opposite edge ofsuch stock 10. Theouter segments such stock 10 is unstressed. The diagonal segments extend generally along diagonal lines when thestock 10 is unstressed. The diagonal segments includediagonal segments diagonal segments shaped apertures 30. The cross segments includecross segments outer segments 22, at one edge andcross segments 36, 38, joined directly to theouter segments 24 at the opposite edge, andcross segments 40 extending between theapertures 30. - While the preferred embodiment of the invention shows
segments segments segments segments - Because the
carrier stock 10 is formed with the generally diamond-shaped apertures 30 defined by thediagonal segments such stock 10. There are consequent savings in cost and weight. - The
carrier stock 10 is formed, for eachindividual carrier 20, withjunctions 42 where each of the diagonal segments is joined to three more of the diagonal segments. Eachjunction 42 is generally X-shaped with anelongate midportion 44, as shown in Figure 2, whensuch stock 10 is unstressed. Also, eachjunction 42 is defined by two pairs of the diagonal segments, namely a first pair comprised of one of thediagonal segments 26a and one of thediagonal segments 28a and a second pair comprised of one of thediagonal segments 28b and one of thediagonal segments 28b. - From each
junction 42, thediagonal segments carrier stock 10. From eachjunction 42, thediagonal segments such stock 10. - Each of the
diagonal segments first end 46 where it is joined to one of thecross segments second end 48 where it is joined at one of thejunctions 42. Moreover, each of thediagonal segments carrier stock 10 is unstressed. Specifically, thesecond end 48 of each of thediagonal segments first end 46. - The wider characteristic of the second ends 48 serves to better accept the high stress placed on these regions of the bands as a result of the frictional contact between camming plates P (shown in phantom lines in Fig. 2) and the
junction 42. - Furthermore, each of the
diagonal segments such stock 10 is unstressed. One of the curved edges is convex and borders one of theapertures 14. The other curved edge is convex. - Each of the
diagonal segments 26bjunction 42 than at thecross segment 40, when thecarrier stock 10 is unstressed. Moreover, each of thediagonal segments such stock 10 is unstressed. - Moreover, for each
individual carrier 20, thecarrier stock 10 may be formed with anintegral handle 50 formed at theouter segments 22. Thehandle 50 has two ends 52 and amiddle leg 54 between the ends 52. Themiddle leg 54 is joined to a node (where theouter segments 22 are joined) via aperforated line 56 defining a break-away joint. The break-away joint enables themiddle leg 54 to be easily broken away from other portions of thehandle 50 when lifted, but remains tied to the outer band segment to assist in winding of the product in the production mode. Once themiddle leg 54 has been broken away, thehandle 50 and theouter segments 22 define a finger aperture that can be sufficiently large to accommodate two or more fingers of a user's hand. - Further details of the juncture of each
end 52 of thehandle 50 to other portions of thecarrier stock 10 and of the characteristic shape of certain aperture-defining edges 64 (which are configured withconcave sections 66 andconvex sections 68 defining nubs 70) are disclosed in a co-pending European patent application no.          filed simultaneously herewith, under Attorneys Reference 80/4019/02, and claiming priority from USSN 519,858. - When the
carrier stock 10 is applied, as by the machine discussed above, lateral forces are applied to theouter segments 24, as suggested by arrows in Figure 2. These forces tend to stretch the band segments, particularly but not exclusively thediagonal segments junctions 42, as shown in Figures 2 and 5, and produce considerable friction between such plates P and thejunctions 42. Consequently, theband segments junctions 42 tend to be particularly vulnerable to necking down or breaking due to this excessive stress concentration. - Because of its characteristic features including the progressively changing widths of the
diagonal segments carrier stock 10 is unstressed, thecarrier stock 10 can be effectively applied to the side walls of thecontainers 12, as by the machine discussed above, with minimal risk of necking down or breaking of any of thediagonal segments - Preferably, the
carrier stock 10 has an asymmetrical configuration, as disclosed in US-A-4,356,914. - As shown in Figure 4, in which an alternate embodiment of this invention is shown, the
handles 50 for eachindividual carrier 20 may be omitted from thecarrier stock 10 and band segments 58 serving as fingergripping means may be provided instead, as disclosed in US-A-4,018,331.

   applying transverse stretching forces to opposite edges of the stock to reconfigure the apertures, and
   applying downward and linearly directed longitudinal forces to the junctions of the stock by camming plates to position the stock downward on the side walls of the containers
   wherein the widened portions of the diagonal segments accept the stress created by the camming plates without necking down or breaking said diagonal segments.
