The package body comprises a handle joined to the side, the handle comprising polymeric film and an elongated grip portion having an elongated grip portion width and an elongated grip portion length. The elongated grip terminates at and gradually widens into two end portions, each of the end portions having an end portion width which is greater than the elongated grip portion width. The end portions are each adhered to the polymeric shell on the side; and wherein the package has a Handle Ratio (Side Area to Handle Area) of at least about 5.
The invention relates to packages for consumer goods, particularly large, flexible film packages.
BACKGROUND OF THE INVENTIONConsumer goods are often packaged for convenience in transportation by the consumer. Often such goods are packaged in flexible film packaging. Flexible film, including plastic polymer films serve not only as a container for the goods, but also serve to protect the goods against the elements, and as well provide a place for the manufacturer to print or otherwise indicate brand information.
Often consumer goods are packaged for economy in large packages. For example, the consumer goods, including food, toiletries, paper goods, and the like sold in “club” stores such as Sam's Club and Costco, often come in large, bulky, and/or heavy packaging. While such packaging serves to offer the consumer an economic benefit in the form of lower prices per unit of goods, such packaging presents many challenges related to transport.
The large, bulky nature of large-count packages of paper goods, such as paper towels, for example, illustrates the problems with such packaging. Large-count packages of paper towels can have a relatively light weight, but a volume and shape that make them difficult for consumers to carry without the risk of unwanted bag dropping or excessive effort in the process. Furthermore, consumers desire convenience and look for product features that provide such convenience, and less work.
Many large packages within the paper towel or bath tissue categories are formed with gussets on the ends of the bulk pack that create folds which can be used as a handle to help consumers carry the packages. However, gusset seals are not always reliable for use as handles as they can rip or tear when handling. Moreover, efforts at alleviating the problem of transportation are complicated by the relatively weak nature of plastic films, which themselves are typically very thin for cost and weight purposes.
Even when the gussets and film have been designed reliably, the use of the gussets can put a large strain on the forearm muscles. As the packages get heavier, the forearm muscles can have more difficulty holding the package and thus the effort at carrying the package becomes considerably more uncomfortable to the consumer.
Relatively large bags without gusset seals are even harder to handle, as there is often no excess polymer film wrap material for which a consumer can grab and hold the package. Carrying a relatively large package with two hands, i.e., in a “hugging” position can present a risk of tripping, as the package can block the user's line of sight.
Accordingly, there is a continuing unaddressed need for a solution to the problems associated with carrying, moving, or otherwise transporting relatively large, bulky packages of consumer goods.
SUMMARY OF THE INVENTIONA package comprising a package body, the package body comprising a polymeric shell defining at least one side and a package volume is disclosed. The polymeric shell comprises a polymeric film having a thickness between at least about 0.6 mils and about 4 mils. The package contains product, the product having a weight of between 2 and 20 pounds. The package body comprises a handle joined to the side, the handle comprising polymeric film and an elongated grip portion having an elongated grip portion width and an elongated grip portion length. The elongated grip terminates at and gradually widens into two end portions, each of the end portions having an end portion width which is greater than the elongated grip portion width. The end portions are each adhered to the polymeric shell on the side; and wherein the package has a Handle Ratio (Side Area to Handle Area) of at least about 5.
A package suitable for the benefits of the present invention is shown in
The dimensions of the top, bottom, and sides define a width w, a depth d, and a height h which define an overall package size and an interior package volume. Each of w, d, and h, can be between about 6 inches and 36 inches, including every ⅛ inch increment in between. In an embodiment, d=13.25 inches, w=20.0 inches, and h=22 inches. In an embodiment, d=20.0 inches, w=13.25 inches, and h=22 inches. In an embodiment, package 10 contains rolled absorbent products, the package weighing about 15 pounds.
Dimensions and parameters calculated from dimensions, including area of a side or volume of a package, can be determined by applying the GSDN Package Measurement Rules GS1 Standards Document, Issue 1.10, July-2009. The package can contain multiple rolls of unwrapped rolled paper products. The package can contain rolled paper products which are themselves individually wrapped, such as wrapped in smaller groups of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15 rolls.
Package 10 can be made of flexible materials known to be suitable for packaging, including polymer films, which can include polymeric films, which can be referred to as a polymer film overwrap. The polymer can include polyolefins such as polyethylene and polypropylene, nylon, or sustainable materials such as thermoplastic starches or polylactic acid. Polymeric materials can be processed as known in the art, such as by flow wrap processes to receive and enclose consumer products 22. In an embodiment, a tube of polymeric film is made by edge sealing two longitudinal edges into a seam which becomes seam 18 of package 10. One of the ends of the tube can be sealed closed, such as by adhesive or heat sealing to make a gusset seal 20 of package 10. Once consumer products 22 are introduced into the open end of the tube so formed, the remaining open end can be sealed in another gusset seal 20 to form a package like the package illustrated in
In an embodiment, package 10 can be formed and sealed by any method known in the art, including by hand folding and sealing. Package 10 can be completely sealed to prevent any air or moisture form entering, or it can be sealed sufficiently to prevent products 22 from falling out. That is, package 10 need not be completely or hermetically sealed, but it can be if desired.
Because package 10 can be large and unwieldy to move and carry, package 10 can be modified to have a handle, such as handle 24 shown in
Handle 24 can be made of polymer film, and can have a shape described as dog bone or hourglass shaped; that is, handle 24 is generally narrow in an elongated grip portion 28, and wider at each end portion 26. The wider end portions 26 can be joined to package polymer film, for example at top 16, as shown in
Furthermore, the package polymer film may have tear resistance to prevent propagation of tears at the stress points at the edge of the handle and film interface. As stress points during lifting can result in thinned film or small holes in the film, poor tear resistance can result in large openings where product could escape. In an embodiment, a tear resistance (ASTM D-1922) can be greater than 100 g. In an embodiment, a tear resistance (ASTM D-1922) can be greater than 200 g. In an embodiment, a tear resistance (ASTM D-1922) can be greater than 300 g. In an embodiment, a tear resistance (ASTM D-1922) can be greater than 100 g in a cross machine direction, and greater than 200 g in a machine direction. In an embodiment, a tear resistance (ASTM D-1922) can be greater than 100 g in a cross machine direction, and greater than 300 g in a machine direction.
Handle 24 can have various shapes and sizes, depending on the size and weight of the package 10.

As shown in
In an embodiment, elongated grip portion 28 of handle 24 can be lightly joined, such as with releasable, light tack adhesive, so that during shipment and display handle 24 is kept generally adjacent top 16 and gap g is effectively 0.0 inches, but upon gripping by a consumer desiring to move or lift package 10 the elongated grip portion 28 can be un-joined, and lifted away from top 16 to permit a users fingers and hand to effect lifting of package 10 by handle 24.
In an embodiment, handle 24 can be a laminate of two or more layers, and the layers can each be the same or different materials. For example, handle 24 can be a multilayer polymer film, with various layers being employed for characteristics such as low cost, high strength, softness, bending modulus, and the like. In one embodiment, handle 24 can include, at least in the elongated grip portion 28, a layer of material that is intended to provide to the consumer using handle 24 a soft, tactile impression. In an embodiment, the soft, tactile impression can be associated with product 22 inside. For example, if product 22 is a cellulosic paper product, a layer 30 of the same or a similar cellulosic paper can be laminated on one or both sides of handle 24, so that when a user uses handle 24 he or she can feel the cellulosic paper product. In the embodiment shown in
In an embodiment, handle material and/or package material can be designed for sustainability. In some flexible film packages, handles integral with the packaging, that is, they are built into the design of the film materials themselves. These are often accomplished by die cutting a hand hole in a location of the bag. This can be advantageous as it can minimize the impact to the complexity of the manufacturing process. However, the film materials must be reinforced or “upgauged” to support the strain induced in the film through the handle when the handle is used to lift the package. While the impact to the manufacturing process and potential capital investment to make such integral handles may be low, the necessary increase in the amount of material used in packaging can be expensive and have a greater negative environmental impact. By utilizing a separate handle that can work with relatively low gauge, existing or slightly modified films, the consumer can experienced the improved portability and convenience with minimized increased cost or environmental impact.
The location of handle 24 on package 10 can be determined such that the placement enhances the packaging or the user experience. For example, as shown in
In another embodiment, as shown in
In an embodiment, distance HD can be from about 10% to about 49% of either the width w or depth d as disclosed with respect to
In an embodiment, as shown in
Offset handle 24, as shown in
In an embodiment, handle 24 is oriented generally parallel to the MD direction of the polymer film overwrap, where MD stands for machine direction and it the direction of the polymer film overwrap manufacture in the length direction as is known in the art. The MD direction is indicated in
In an embodiment, the location of handle 24 can be positioned over an intended opening 36 to package 10, such as shown in
In an embodiment, the location of handle 24 can be determined to be over an intended opening 36 to package 10, and be a functioning part of opening 36, such as shown in
Package 10 with a handle 24 on one side 16 thereof can be implemented in various embodiments, as shown above. In an embodiment, side 16 has an area, which can be determined according to accepted methods as disclosed in the above-mentioned GSDN Package Measurement Rules GS1 Standards Document, Issue 1.10, July-2009, or by measuring to plus/minus 1 inch with a standard measuring instrument, such as a measuring tape, measured to the closest ⅛ inch as determined by the naked eye. The area of a handle can be calculated from the electronic file used to design it, or by methods known in the art, such as by weighing the handle and calculating the area based on the density of the material and its thickness.
In an embodiment, package 10 can have two or more handles. For example, the package 10 shown in either of
In an embodiment, the package 10 can have a Handle Ratio, which is the ratio of the side area to the handle area, of from about 5 to about 50, and every whole number increment in between.
As used herein, the terminology “increment in between” or the like in the context of ranges of dimensions is intended to be explicit disclosure of each unit so described. By way of example, disclosure of a “length between 1 inch and 2 inches and every ⅛ inch increment in between” is explicit, claimable disclosure for 1 inch, 1⅛ inch, 1¼ inch, 1⅜ inch, 1½ inch, 1⅝ inch, 1¾ inch, 1⅞ inch and 2 inches.
The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
