Definitions

• This invention relates to a label that provides an integrated handle, particularly for use with large containers.
• PET bottle containers are typically used for soda, juice and similar beverages. As the size of these bottles increases, they become more difficult to transport, grasp and pour. Commonly, large PET bottles, such as 2 liter bottles, include smooth sidewalls that may prove slippery when wet and/or cold. Such difficulties are compounded by the large diameters of such bottles that make grasping and pouring with one hand difficult.
• a sleeve according to this invention is used to label and carry one or more containers such as large PET bottles.
• Individual sleeves preferably comprise a folded low density flexible plastic sheet that includes a label and an integrated handle.
• the sleeve further includes a pair of seals that extend across the sleeve to define a sleeve opening and the handle together with a handle aperture for grasping, transporting and pouring the container.
• Fig. 1 is a side elevational view of an elastic sheet according to one preferred embodiment of this invention
• Fig. 2 is a side elevational view of an elastic sheet including two seals according to one preferred embodiment of this invention
• Fig. 3 is a side elevational view of a plurality of sleeves according to one preferred embodiment of this invention.

• Figs. 1-4 show sleeve 10 for labeling and carrying container 80, according to various preferred embodiments of this invention.
• Containers 80 such as those shown in package 90 in Fig. 4, are preferably PET bottles, typically large size PET bottles, such as those accommodating 2 liters, 48 ounces, 64 ounces, 96 ounces or other suitable quantities of product, such as soda or juice.
• PET bottles are shown in Fig. 4, similar containers 80 may be used with sleeve 10 according to this invention.
• Sleeve 10 is preferably stretchingly engaged around container 80 to create package 90, such as package 90 shown in Fig. 4.
• Sleeve 10 preferably comprises a flexible plastic sheet, such as an elastic material 15 preferably constructed from a flexible, resilient material such as, in one preferable embodiment, low density polyethylene.
• the elastic material 15 may have a thickness of about 1-20 mils, suitably about 2-4 mils.
• the elastic material 15 used to form sleeve 10 is formed using a polymer composition which includes a high pressure low density polyethylene polymer.
• the composition provides the sleeve 10 with improved recovery after stretch, improved elongation and strength at break, and improved resistance to tearing when the sleeve is notched or scratched.
• the low density polyethylene polymer should have a density of about 0.910-0.950, grams/cm 3 , suitably about 0.920-0.940 grams/cm 3 , desirably about 0.925-0.935 grams/cm 3 .
• Alow density polyethylene polymer ⁇ includes polyethylene polymers commonly considered as having medium density, as well as polyethylene polymers commonly considered as having low density.
• Elastic material 15 is preferably extruded into sheets which are cut, using means known to those skilled in the art, such as a stamping die, to form a plurality of sleeves 10. Each sleeve 10 is preferably formed to sufficiently engage a respective container 80.
• Elastic material 15 is preferably printed with label 30.
• Label 30 preferably includes one or more of graphics, product information, nutritional information, pricing, promotional offers and/or other suitable material germane to the marketing, sale and use of the respective container 80.
• elastic material 15 includes a fold 20 along one edge to form two layers of elastic material 15.
• a double thickness of elastic material 15 is sealed along one edge to form an openable sleeve 10 such as shown in Figs. 3 and 4.
• Fig.2 shows a pair of seals 25 aligned along one edge of elastic material 15.
• Seals 25, including inner seal 27 and outer seal 29, preferably connect the double thickness of elastic material 15 along an opposite edge of fold 20.
• Inner seal 27 of the pair of seals 25 preferably forms elastic material 15 into a generally continuous sleeve 10 sized to stretch around container 80.
• each of the pair of seals 25 are preferably positioned along the one edge of elastic material 15 opposite fold 20.
• two seals 27, 29 are shown in Fig. 2, the invention may include a single seal 25 or more than two seals 25 positioned along elastic material 15.
• seals 25 preferably comprise a pair of welds positioned between two layers of elastic material 15. As shown in Figs. 2-4, seals 25 preferably extend transversely across sleeve 10. Seal 25 may comprise any suitable reinforcement that joins two or more layers of elastic material 15 together. The two or more layers of elastic material 15 may be welded, or otherwise joined together to create flexible sleeve 10. ASeal ⁇ as used in the specification and claims may be defined as a hot weld, cold weld, lamination or any other manner of connection that joins two sheets of material known to those having ordinary skill in the art.
• sleeve 10 is formed and delineated from handle 40.
• handle 40 is positioned to project from sleeve 10 and container 80.
• Handle 40 further includes handle aperture 50 formed in elastic material 15 between the pair of seals 27, 29.
• Handle aperture 50 is preferably positioned to provide an ample area for a purchaser to grab by inserting his hand or fingers through and still maintain the integrity of package 90.
• handle 40 includes two layers of elastic material 15 joined by seals 27, 29. Additional layers of elastic material 15 may be used in handle 40 by creating a gusset or similar arrangement to permit a thicker, more robust handle 40 relative to the remainder of sleeve 10.
• seals 25 assist handle 40 in adding stiffness so that handle 40 projects from container 80 and facilitates lifting package 90.
• Such seals 25, particularly seal 27, also preferably add material thickness and/or width along edge of sleeve 10 which bears a significant amount of stress during the application process to containers 80.
• seals 25 comprise a width of 1/16" to 1/4" thereby sufficiently reinforcing sleeve 10 during application and use.
• a resultant and representative package 90 preferably includes a bottle having sleeve 10 stretched around the bottle. As described, sleeve 10 is preferably printed with informational material regarding the bottle.
• a first weld or inner seal 27 preferably extends across a length of sleeve 10 and is positioned along a sidewall of the bottle. Handle 40 accordingly extends from inner seal 27, as shown in Fig. 4. As shown, handle 40 preferably extends outwardly from the bottle.
• a second weld or outer seal 29 preferably extending across an end of handle 40, such as shown in Figs. 3 and 4.
• Handle aperture 50 extends through handle 40 and is preferably positioned within handle 40 between the inner seal 27 and the outer seal 29.
• Sleeves 10 are preferably applied to containers 80, namely PET bottles, around a sidewall of the respective container 80.
• sleeve 10 is applied around an approximate lower third of container 80 to maintain a maximum frictional engagement between sleeve 10 and the sidewall of container 80.
• sleeve 10 is preferably manufactured so that raw sleeve stock includes a generally continuous roll of elastic material 15 having a plurality of adjacent sleeves 10 that are punched and then wound onto a spool (not shown) having several thousand sleeves 10, each sleeve 10 attached to each adjacent sleeve 10, as described in more detail below.
• Sleeves 10 are later applied to containers 80 to form packages 90 and, during such process, are preferably unwound from spools and then separated from each other to form individual packages 90.
• each sleeve 10 in the generally continuous roll of sleeves is line of weakness 35.
• each sleeve 10 Prior to, or during, the process of applying sleeves 10 to containers 80, each sleeve 10 may be separated from each adjacent sleeve along line of weakness 35.
• Lines of weakness 35 may comprise perforations, serrations, slits, reduced thickness or combination thereof formed in elastic material 15 and are preferably tearable or frangible to permit separation of elastic material 15 along a defined line.
• a method of packaging containers 80 preferably includes providing a generally continuous elastic material 15 having a plurality of sleeves 10 each having a respective handle 40.
• Such sleeves 10 optimally form a single carrying handle 40 for a single container 80, such as large PET bottles, as described herein.
• containers 80 are positioned in each container aperture 30 using equipment capable of stretchingly engaging sleeve 10 with container 80.
• each container 80 therefore includes a sleeve 10 positioned about its sidewall that labels container 80 and enables convenient carrying of container 80.
• the resulting package 90 of one container 80 may then be lifted and carried using handle 40.
