DETAILED DESCRIPTION

(12) FIG. 1 shows a container 20 comprising the assembly of a bottle body 22, a drain-back spout fitment 24, and a cap 26 (which may serve as a measuring/dispensing cup). Each may be made as a unitary plastic molding. Exemplary bottle body material is high density polyethylene (HDPE). Exemplary spout fitment and cap material is polypropylene.

(13) The exemplary body 22 comprises a unitary combination of a base 30, a sidewall 32 extending upward from the base, a shoulder 34 at an upper end of the sidewall, and a neck 36 extending upward from the shoulder to a rim 38 and defining an opening 40 having a central longitudinal axis 500. The bottle body has an interior surface 42 and an exterior surface 44. A handle 46 (FIG. 1) may extend from the sidewall and the body interior may extend through the handle. An upper portion 50 of the neck bears an external thread 52. The external thread 52 engages an internal thread 54 of an outer wall 56 of the spout fitment. The spout fitment has an annular rim or flange portion 60 joining an upper end of the outer wall 56 to the upper end of an inner wall 62.

(14) FIGS. 2-8 show further details of the cap/cup 26. The cap/cup 26 comprises a sidewall 100 which extends from a first end at a junction with a transverse web 102 to a second end forming a rim 104. When the cap/cup is used as a cap, the transverse web 102 forms a top of the cap. When used as a cup, the transverse web forms a base/bottom of the cup. The transverse web includes an interior surface 108 (FIG. 3) and an exterior surface 110 (FIG. 4). Similarly, the sidewall has an exterior surface 112 (FIG. 4) and an interior surface 114 (FIG. 2). In the exemplary embodiment, a flange 116 protrudes radially outward from the sidewall exterior surface and has an underside 117. The flange 116 essentially separates a first portion 118 of the sidewall (between the flange and the transverse web and being an upper portion when serving as a cap) from a second portion 120 (between the flange and the rim 104). The second portion 120 bears an external thread 122 for mating with the internal thread 124 (FIG. 1) along the inner wall 62 of the exemplary spout fitment.

(15) Along the first portion 118 of the sidewall, the exemplary sidewall bears a plurality of axial/longitudinal ribs 130 with spaces/channels 132 therebetween. These provide for gripping by the user to screw the cap on and unscrew it.

(16) FIG. 5 shows yet further details of the exemplary cap/cup. The interior surface 114 bears a plurality of fill indicia. Each exemplary indicia comprises the combination of an alphanumeric indicia 140-1, 140-2, 140-3, 140-4, and 140-5 with a respective geometric indicia 142-1, 142-2, 142-3, 142-4, and 142-5. Each of the exemplary alphanumeric indicia comprises a molded-in protrusion. The exemplary alphanumeric indicia are, respectively: “A”; “1”; “2”; “3”; and “4”. These indicate progressively higher fill quantities/doses.

(17) In the exemplary implementation, each of the first four indicia are circumferentially spaced from each other. Each of the exemplary first four graphical/geometric indicia comprises a sidewall structure 150 (FIGS. 6A&B) forming a raised boundary/perimeter at least partially surrounding a textured enclosed region 152 of the sidewall interior surface. An exemplary height H.sub.1 of the raised boundary/perimeter is 0.010 inch (more broadly, 100-500 micrometer or 200-300 micrometer) above the surrounding interior surface. An exemplary width W.sub.1 of the raised boundary/perimeter is 0.020 inch (more broadly, 0.2-1.0 mm or 0.4-0.6 mm). An exemplary overall indicia width is 0.439 inch (more broadly, 5-20 mm or 8-15 mm). An exemplary overall graphical indicia length L.sub.1 may, in the particular example, vary progressively from indicia to indicia to correspond with the dose and, thereby, provide yet further emphasis of which dose is involved. Exemplary individual indicia may be an exemplary 0.2-1.5 inch (5-38 mm) with a progressive change totaling at least fifty percent from the smallest indicia to the largest indicia.

(18) The exemplary texturing of region 150 is schematically shown via diagonal hatching. An example of such texturing is rougher/coarser than the smooth surface therearound (e.g., a fine orange peel texture or a more coarse/grit-like. The texturing may be generated by local electrodischarge machining (EDM) or other roughening of the tool (mold). With a transparent or nearly transparent cap, the texturing may create a more opaque local area of relative translucence. Exemplary texture as applied to the tool is Mold-Tech MT-11050 (Standex International Corporation, Salem N.H., US) texture (more broadly MT-11010 (25 micron average depth)-MT-11050 (110 micron average depth) or other EDM equivalent).

(19) Each exemplary graphical indicia comprises a protuberant end region 154 (an upper end when in the rim-up cup orientation). Lateral portions of the boundary at least partially converge toward the web (i.e., project toward the web and converge toward each other). For example, the exemplary sidewall has a circumferentially extending end portion 156 with a pair of lateral sidewalls extending therefrom toward the web. Each exemplary lateral sidewall comprises a proximal portion 158A, 158B, and a distal portion 160A, 160B. In the exemplary embodiment, the proximal portions are essentially axial and the distal portions converge at an off-axial angle θ (e.g., 26°, more broadly, 20-65°, 20-45° or 28°-35°). θ may change from indicia to indicia. Particularly in the case of transparent or translucent caps, the angling of these sidewall portions 160A, 160B helps visually distinguish them from traces of the axial ribs seen through the cap/cup sidewall 100.

(20) Exemplary lengths of the distal portions 160A, 160B are 0.228 inches (more broadly, 4-10 mm). Exemplary lengths of the proximal portions 158A, 158B may, as noted above, vary from indicia to indicia proportional to the dosage. FIG. 6A also shows a radius of curvature R.sub.1 between the end portion 156 and proximal portions and a radius of curvature R.sub.2 between the proximal portions and associated distal portions. A R.sub.3 may be present at the lower/distal ends of the distal portion (e.g., convexly rounding the end of the border). Exemplary R.sub.3 is 0.03 inch (more broadly 0.5-1.5 mm).

(21) The exemplary fifth fill indicia is a relatively high indicia and its graphical component 142-5 may be a conventional circumferential linear level indicator (e.g., formed as a raised rib). Alphanumeric indicator height may be similar to perimeter height H.sub.1. Rib height may be similar. Rib width may be greater than perimeter width. Alphanumeric indicator planform (font) size may be an exemplary 4-10 mm in character height.

(22) One or more embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, implemented in the reengineering of an existing cap/cup or container, details of the existing cap/cup may influence details of any particular implementation. Accordingly, other embodiments are within the scope of the following claims.
