Problems solved by technology

Of course the problem with curved surfaces is that objects are not readily stably perched thereon.
Curvature presents stackability problems.

Embodiment Construction

[0022]We have found that use of a pair of crescent shaped indents (curved grooves) prevent slippage. The indents prevent not only a stacked jar from sliding off the roof panel of another jar but they also prevent a sideways fall. The crescent geometry of the present invention ensures that both directions of instability on a cap closure can be minimized.

[0023]FIG. 1 illustrates the jar 2 of the present invention. This package includes a non-circular container body 4 having a closed end 6 defined by a bottom panel 8 and an open end defined by a mouth 12.

[0024]A cap closure 14 is placed over the open end 10 of the container body.

[0025]FIG. 1 illustrates a fully closed position of the cap closure. FIG. 4 illustrates an open position. The cap closure includes a fitment 16 engageable around the mouth 12 and supported on the container body. A lid 18 is hingedly connected to the fitment. The lid is defined by a roof panel 20 having a domed upper surface.

Abstract

A jar (2) for a cosmetic product is provided which includes a non-circular container body (4) and a cap closure (14). The container body (4) features a closed end (6) defined by a bottom panel (8) and an open end defined by a mouth (12). The bottom panel (8) on an exterior surface is formed with projecting crescent shaped symmetrically disposed feet (66). The cap closure (14) includes a fitment (16) engageable around the mouth (12) and supported on the container body (4). A lid (18) is hingedly connected to the fitment (16) and defined by a roof panel (20) having a domed upper surface. The upper surface includes a pair of crescent shaped indents (24, 26) formed symmetrical to each other along opposite edges of the roof panel (20). The crescent shaped indents (24, 26) allow stacking of one jar upon another with good stability. The domed (curved) roof panel (20) distributes force (from stacked jars) more evenly along the cap closure (14). This permits a decrease in jar wall thickness which leads to a reduction in plastic weight.

Description

BACKGROUND OF THE INVENTION[0001]The invention concerns jars which have domed lids and are structured to be stackable one upon another.[0002]Ordinarily the term “jar” refers to a squat large-mouthed container. In the cosmetics art, jars are the packaging of choice for cold creams and for petrolatum. Indeed, petrolatum jars sold under the trademark of VASELINE or VASELINOS are the premier jar cosmetic products. Since these packages are proportionately squat, retailers need to stack one jar upon another to efficiently utilize store shelf space. Stackability is also a desirable feature in transport of these packages from manufacture to the retail store.[0003]Environmental concerns and economics provide an incentive to light weight packages. Excess plastic desirably should be removed from packaging. Ordinarily jars need to be stackable to conserve space. A certain amount of plastic is needed to render walls of the jar sufficiently sturdy for stacking.[0004]We have found that curved (dom...
