Field of the Invention
This invention relates to a container carrier having at least three rows of container receiving apertures for unitizing a plurality of containers.
Description of Prior Art
Conventional container carriers are often used to unitize a plurality of similarly sized containers, such as cans, bottles, jars and boxes and/or similar containers that require unitization. Flexible plastic ring carriers are one such conventional container carrier.
Flexible plastic ring carriers having a plurality of container receiving apertures that each engage a corresponding container may be used to unitize groups of four, six, eight, twelve or other suitable groups of containers into a convenient multipackage. Flexible ring carriers may include a handle that extend upwardly from the carrier to enable a consumer to carry the package from the top (called a “top lift carrier”) or outwardly from a side of the carrier to enable a consumer to carry the package from the side (called a “side lift carrier”).
Typically, larger-capacity carriers result in challenges in application to containers in that carriers having more than two rows tend to open in an undesirable sequence and thus cannot be applied at high speeds. In addition, the resulting package tends to sag at the ends when lifted resulting in a sloppy appearance. As such, a need arises for a carrier capable of carrying a large number of containers that permits high speed application and results in an aesthetically pleasing package for the consumer to handle.
The present invention is directed to a flexible carrier for packaging containers that includes an arrangement of container receiving apertures that are configured to permit placement over containers in three distinct rows.
The carrier is suitably configured with a combination of webs and container receiving apertures that permit opening up and generally even, distributed stretching for application to the containers. In the described configuration, a flexible sheet forms webs defining container receiving apertures wherein tapered oblique bands at least partially define the respective container receiving apertures and a handle is positioned parallel with the three rows of container receiving apertures. The resulting carrier is configured to enable placement over at least three rows of containers to result in a tight, unitized bricklike package.
The above-mentioned and other features and objects of this invention will be better understood from the following detailed description taken in conjunction with the drawings wherein:
Containers are preferably cans, however, bottles or any other commonly unitized container may be used with flexible carrier 10 according to this invention. The containers are preferably, though not necessarily, like-sized within a single flexible carrier 10.
Each flexible carrier 10 preferably includes a single layer of flexible sheet 20 having a width and length defining therein a plurality of container receiving apertures 25, each for receiving a container. The plurality of container receiving apertures 25 are preferably arranged in at least three longitudinal rows and multiple longitudinal ranks so as to form an array of container receiving apertures 25, such as three rows by two ranks for a six container multipackage as shown in
A preferred carrier configuration includes three distinct parallel rows of container receiving apertures 25 including a middle row and two outer rows of container receiving apertures 25. Each rank includes three container receiving apertures 25 (one for each row in the carrier 10). Of these three container receiving apertures 25 per rank, there are two outer apertures and one center aperture formed therebetween.
As shown in
Container receiving apertures 25 are preferably formed in a geometry that results in a uniform application of the carrier 10 to containers to produce a tight unitization of containers within flexible carrier 10. Such a result is difficult when carrier 10 is engaged with three rows of container receiving apertures 25 over three rows of containers as described herein.
In particular, one or more jaws engage with an edge of the container receiving apertures 25 in outer rows and stretch the carrier open so as to apply the carrier to individual containers. When an intermediate row is formed between the outer rows, the jaws cannot directly engage container receiving apertures in that row which results in inadequate stretching of the container receiving apertures in that row and/or misapplication of the carrier to the plurality of containers. The subject invention is configured to enable that the container receiving apertures 25 in that intermediate row to adequate stretch and engage the associated containers resulting in a desired package shown in
In particular, the subject carrier 10 preferably stretches between approximately 31% and 51% thereby permitting application to a range of container diameters from 2.25″ to 2.6″.
As described above, container carrier 10 according to a preferred embodiment of the invention includes a series of interconnecting webs 30 that define the plurality of container receiving apertures 25. Webs 30 are stretchable around container during application and recoverable around container following application. Specifically, in the described configuration, the flexible sheet 20 forms webs 30 defining container receiving apertures 25 wherein the webs 30 are tapered oblique bands 35 at least partially defining the respective container receiving apertures 25. In particular the oblique bands 35 taper toward the web between the rows of container receiving apertures 25.
In addition, according to one embodiment container receiving apertures 25 in the outer rows are longitudinally asymmetric while the container receiving apertures 25 in the middle rows are longitudinally symmetric. The particular arrangement of apertures described enables the carrier 10 uniformly open up and stretch for application to containers despite having three rows of container receiving apertures 25.
As shown in
According to an embodiment of the invention shown in
As shown in the figures, the container carrier 10 may further include asymmetric dividing apertures 70 positioned between adjacent ranks of container receiving apertures 25. Further, dividing apertures 70 are preferably positioned between adjacent carriers 10 when formed in a generally continuous string of carriers prior to application.
In addition, a slit 75 is preferably positioned between each container receiving aperture 25 in a center row and an outer row. The slit 75 also assists in a desired v-shape in the center web of the carrier following application to containers.
The configuration of the carrier 10 described above includes a combination of webs and container receiving apertures that permit opening up and even stretching for application to the containers. In the described configuration, the shape and design of the center row of container receiving apertures 25 is different from that of the outer rows of container receiving apertures 25. Such a design overcomes the natural tendency of the central apertures to foreshorten during stretching.
As described, the subject carrier 10 preferably accommodates at least four different standard container sizes including 202/211; 202/209; 202/207.5 and 202/206.5 (2.6″; 2.48″; 2.36″; and 2.25″ diameters, respectively). Standard container heights between approximately 250 ml to 568 ml can also utilize the subject carrier 10. In an applied condition, adjacent containers touch in a transverse direction (TD) and are spaced at various intervals depending on container size in the longitudinal or machine direction (MD). The flexibility of the carrier 10 thereby permits a single applicating machine and carrier to accommodate a whole range of containers without changeover to a new carrier. This enables a more compact footprint for equipment, minimizes required inventories for carrier stock and simplifies changeover to different multipackages.
While in the foregoing specification this invention has been described in relation to certain preferred embodiments thereof, and many details have been set forth for purpose of illustration, it will be apparent to those skilled in the art that flexible carrier 10 and package 100 susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
