Patent Application
20070007236
The present invention relates to a container for holding and dispensing liquids, particularly liquid household products that are displayed at point of sale.
There is a growing trend to offer consumer products in larger sizes in discount and warehouse stores, and price clubs. Packaging that is designed for holding and dispensing liquid products require a handle when the package exceeds a certain capacity to make them practical for frequent use. Large volume containers used in such applications, especially for liquid products have evolved along two main lines.
Large capacity packages for commodity or industrial liquid products, e.g., mineral spirits, often have a facing that is rectangular in shape with a handle attached near a top of the container. The term facing refers to the overall viewable area within the silhouette of the container that is displayed to the consumer when the product is properly positioned on a supermarket shelf. This “brick shape” provides a large space for labels and graphics (essentially the entire facing) and allows efficient packing of the container on a supermarket shelf.
In contrast branded liquid products such as laundry detergents, fabric softeners, light duty liquids, dishwashing liquids, household liquid cleaners and shampoos for example, incorporate added value ingredient and functionality. The aesthetic qualities, i.e., style, ergonomic properties, and other features of the package contribute to brand differentiation. When viewed from a perspective orthogonal to the face panel, i.e., perpendicular or normal to the plane of the container that faces the consumer, such containers have an arcuate perimeter and a visible handle. This handle is usually integrated into the package design. As a result, the handle and the aperture formed between the handle and the body of the package (the “gripping aperture”) occupies a significant portion of the facing. This design greatly limits the available area on the facing for graphics, i.e., images and text that are printed or embossed directly on the container or on a film or label affixed to the container. For very large capacity packages, the handle and gripping aperture generally occupy an even larger portion of the facing to allow gripping the handle at different locations or balance points for convenient dispensing as the amount of liquid decreases during use.
Thus, it is desirable to develop a handleware container (i.e., container with a permanently attached handle) for household liquid products that has a significantly larger portion of the facing area available for graphics, yet retains the aesthetic and ergonomic properties suitable for value-added branded consumer products.
A variety of ornamental designs for handleware containers, alternatively known as bottles or jugs, have been the subject of design patents. These include: U.S. Pat No. D471,465 to Sikra et al issued on Mar. 11, 2003; U.S. Pat. No. D461,717 to Crawford et al issued Aug. 20, 2002; U.S. Pat. No. D329,816 to Beaver et al issued Sep. 29, 1992; U.S. Pat. No. D323,981 to Satterfield issued Feb. 18, 1992; U.S. Pat. No. D303,929 to U.S. Pat. No. D303,929 to Ross issued Oct. 10, 1989; U.S. Pat. No. D221,516 to Crisci issued Aug. 24, 1971; U.S. Pat. No. D212,210 to Anderson issued Sep. 17, 1968; U.S. Pat. No. D210,443 to Mason issued Mar. 12, 1968; U.S. Pat. No. D208,169 to Platt issued Jul. 25, 1967; and U.S. Pat. No. D206,958 to Anderson issued Feb. 14, 1967.
Ways to improve the dispensing properties of large capacity handleware containers for liquid products have also been described in the art. U.S. Pat. No. 3,434,635 issued to Mason Jr. on Mar. 25, 1969 describes a symmetric container of square cross section having a spout and hollow handle that incorporates a channel or spine at the upper surface of the handle as a means of eliminating “glugging”. U.S. Pat. No. 5,111,979 issued to Athar on May 12, 1992 discloses a symmetric fluid dispensing container having a large U shaped handle that permits different gripping points, and a pour spout.
The present invention seeks improvements over deficiencies in the known art. Among the one or more problems addressed include a handleware container that has a significantly larger portion of the facing area available for graphics, yet retains the ergonomic and aesthetic properties suitable for added-value consumer products.
The inventors have discovered a design for an asymmetric handleware container design in which the front panel effectively masks the gripping aperture when the container is properly oriented on a supermarket shelf. This allows a dramatically increased fraction of the facing area to be utilized for graphics.
Specifically, the handleware container includes a bottom wall panel; vertically oriented front, rear and opposing side wall panels; and a handle joining one of the side panels to form a gripping space; wherein the perimeter of the front wall panel is larger than a perimeter of the rear wall panel; and the gripping aperture is hidden from view by the front wall panel when the container is viewed orthogonal to the front wall panel.
In one suitable embodiment, the front wall panel of the handleware container has a substantially arcuate perimeter and substantially flat and parallel front and rear wall panels.
In another embodiment, a portion of the side panel to which the handle is attached is curved and is asymmetric with respect to a parting line that divides the side wall panel.
In still another embodiment no one wall panel of the container is superimposible on another (i.e., different) wall panel by a symmetry operation or a combination of symmetry operations.
These and other embodiments are described more fully below and in the accompanying drawings.
Further features of the handleware container will now be described in more detail with reference to the drawings in which:
For the avoidance of doubt the word “comprising” is intended to mean “including” but not necessarily “consisting of” or “composed of.” In other words, the listed steps, options, or alternatives need not be exhaustive.
The handleware containers of the invention can be constructed of any moldable polymeric material such as polyethylene or polypropylene and can include non-polymeric materials. The polymeric material can be of a single layer or it can be a laminate. Examples of suitable packaging materials for construcing the instant container are given in U.S. Pat. No. 6,223,845 to Giblin et al issued May 1, 2001 and the references contained therein and is hereby incorporated by reference in its entirety.
The handleware containers of the invention can be of a range of sizes to hold various volumes of liquids from a fraction of a liter to multi-liters, preferably at least about 2.8 liters, and most preferably at least about 3.7 liters.
Referring now to the drawings in detail, wherein like numerals indicate the same elements throughout the views, there is illustrated a preferred embodiment of the handleware container of the present invention.
Container (or bottle or jug) 12 includes a horizontally orientated top wall panel 14, a horizontally orientated bottom wall panel 16, a vertically orientated front wall panel 18, an and opposing vertically orientated rear wall panel 20, and two opposing vertically orientated side wall panels, 22 and 24. By the term “opposing wall panels” is meant wall panels that are on directly opposite sides of the container but are not necessarily parallel.
The container 12 can be fabricated by any suitable technique such as, for example injection blow molding or extrusion blow molding but other thermoforming techniques can also be used.
The top wall panel 14 has a pour spout opening 30 that is bounded by a cylindrical wall 32 whose external surface 32a is preferably threaded to form a boss that accepts an optional cap (not shown). A variety of optional features can be included as part of the pour spout and optional cap. These include, for example, a pour spout fitment with a self-draining feature and/or a measuring cap such as is described in U.S. Pat. No. 4,550,862 to Barker et al issued Nov. 5, 1985 incorporated by reference herein.
The side wall panel 24 although having a curved surface is approximately orthogonal to the front wall panel 18 and the rear wall panel 20 as can be seen from
With reference to
A handle 34 overlies the side wall panel 22 and extends from an upper portion 36 adjacent to the top wall panel 14 downwardly and outwardly to a lower portion 38 adjacent to the bottom wall panel 16. The handle 34 is preferably hollow defining an interior space that communicates (i.e., is contiguous) with the interior chamber that is bounded by the interior surface of the bottom 16, top 14, front 18, rear 20 and side 22, 24 wall panels.
The side wall panel 22 and the handle 34 define a “gripping aperture” 40 which accommodates the hand during handling and dispensing operations. This gripping space is best seen in
The front wall panel 18 and the rear wall panel 20 are preferably predominantly planar. By the term predominantly planer is meant that the fraction of the total surface area occupied by the planar section should be greater than 50%, preferably greater than 75%, and most preferably greater that 85%. However, the term “planar” should be understood as “approximately or predominantly planar” in the practical sense used in the context of the art of packaging for liquids. Thus, front and rear wall panels 18 and 20 respectively) may bow out slightly especially when the container is filled. The extent of bowing depends on the flexibility of the polymeric material used to fabricate the container. Such bowed panel walls are classified as both planar and parallel in the present context.
