Definitions

  • 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.
  • 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.
  • each such container has a chime formed on its upper end, or on each of its ends.
  • 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.
  • 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 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
  • 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.
  • 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.
  • carrier stock 10 for machine application to substantially identical containers 12 constitutes a preferred embodiment of this invention.
  • Such stock 10 is formed with separate apertures 14 to receive the individual containers 12.
  • the carrier stock 10 is severable, along transverse lines to be later described, to form individual carriers 20 that are substantially identical.
  • the containers 12 are beverage cans of a type used commonly for beer, soft drinks, and other beverages. Also, each container 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.
  • FIG 1 a package is shown, which comprises six such containers 12 and one such carrier 20, as severed from such stock 10.
  • One such carrier 20 is shown fully in Figure 2, which also shows fragmentary portions of the next carrier 20.
  • Each carrier 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 for such 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 each individual carrier 20, with integrally joined band segments defining six separate 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 each individual carrier 20.
  • the carrier stock 10 is applied to the side walls of the respective containers 12 away from the chime 16 of each container 12.
  • the stock 10 is designed to be effectively applied by the machine disclosed in the co-pending application noted above.
  • 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.
  • the machine comprises two camming plates P fixed in parallel relation to each other, and in edge contact with the carrier stock 10 as the stock 10 is moved through the machine. Further details of the machine may be found by reference to the co-pending application noted above.
  • the carrier stock 10 is applied to the side walls of the respective containers 12, the carrier 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 of such stock 10 and outer segments 24 extending along the opposite edge of such stock 10.
  • the outer segments 22, 24, extend in a generally longitudinal direction, which is the machine direction, when such stock 10 is unstressed.
  • the diagonal segments extend generally along diagonal lines when the stock 10 is unstressed.
  • the diagonal segments include diagonal segments 26 a , 28 a , and diagonal segments 26 b , 28 b .
  • the diagonal segments define generally diamond-shaped apertures 30.
  • the cross segments include cross segments 32, 34, joined directly to the outer segments 22, at one edge and cross segments 36, 38, joined directly to the outer segments 24 at the opposite edge, and cross segments 40 extending between the apertures 30.
  • segments 26 a and 28 a as curved and segments 26 b and 28 b as straight
  • segments 26 a and 28 a may be straight or segments 26 a and 28 b may be curved without altering the scope and spirit of the invention.
  • the carrier stock 10 is formed with the generally diamond-shaped apertures 30 defined by the diagonal segments 26 a , 28 a , 26 b , 28 b , excess material is omitted from such stock 10. There are consequent savings in cost and weight.
  • the carrier stock 10 is formed, for each individual carrier 20, with junctions 42 where each of the diagonal segments is joined to three more of the diagonal segments.
  • Each junction 42 is generally X-shaped with an elongate midportion 44, as shown in Figure 2, when such stock 10 is unstressed.
  • each junction 42 is defined by two pairs of the diagonal segments, namely a first pair comprised of one of the diagonal segments 26 a and one of the diagonal segments 28 a and a second pair comprised of one of the diagonal segments 28 b and one of the diagonal segments 28 b .
  • the diagonal segments 26 a , 28 a , of the first pair diverge toward the nearer edge of the carrier stock 10.
  • the diagonal segments 26 b , 28 b , of the second pair diverge toward the other edge of such stock 10.
  • Each of the diagonal segments 26 a , 28 a has a first end 46 where it is joined to one of the cross segments 32, 34, 36, 38, and a second end 48 where it is joined at one of the junctions 42. Moreover, each of the diagonal segments 26 a , 28 a , has a progressively changing width when the carrier stock 10 is unstressed. Specifically, the second end 48 of each of the diagonal segments 26 a , 28 a , is wider than its 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.
  • each of the diagonal segments 26 a , 28 a has curved edges, as shown in Figure 2, when such stock 10 is unstressed.
  • One of the curved edges is convex and borders one of the apertures 14.
  • the other curved edge is convex.
  • Each of the diagonal segments 26 b 28 b may also have progressively changing width, i.e., wider at the junction 42 than at the cross segment 40, when the carrier stock 10 is unstressed. Moreover, each of the diagonal segments 26 b , 28 b , has straight edges when such stock 10 is unstressed.
  • the carrier stock 10 may be formed with an integral handle 50 formed at the outer segments 22.
  • the handle 50 has two ends 52 and a middle leg 54 between the ends 52.
  • the middle leg 54 is joined to a node (where the outer segments 22 are joined) via a perforated line 56 defining a break-away joint.
  • the break-away joint enables the middle leg 54 to be easily broken away from other portions of the handle 50 when lifted, but remains tied to the outer band segment to assist in winding of the product in the production mode.
  • the handle 50 and the outer segments 22 define a finger aperture that can be sufficiently large to accommodate two or more fingers of a user's hand.
  • the carrier stock 10 can be effectively applied to the side walls of the containers 12, as by the machine discussed above, with minimal risk of necking down or breaking of any of the diagonal segments 26 a , 28 a .
  • the carrier stock 10 has an asymmetrical configuration, as disclosed in US-A-4,356,914.
  • the handles 50 for each individual carrier 20 may be omitted from the carrier stock 10 and band segments 58 serving as fingergripping means may be provided instead, as disclosed in US-A-4,018,331.
