ABSTRACT

A dispenser assembly (2) is disclosed comprising a cylindrical canister (4), a cylindrical lid (6), and a cylindrical cap (8). The lid component (6) encloses the top of the canister body (4) and includes at least one profiled dispenser aperture (28 or 30). The dispensing aperture is configured to include an arcuate body side (32) which is disposed adjacent to the peripheral rim of a top surface (22) of the lid (6). A linear side (34) of the aperture extends between opposite ends of the curved arcuate side (32).
Elongate pasta is stored in the canister and is portioned out through either aperture (28 or 30). Because of the shape of the apertures, pasta can be accurately portioned out until the canister is substantially depleted. The cap (8) and the lid (6) are provided with outward extending flanges (42, 26, respectively) which align in a co-planner relationship with internal surfaces of the canister, whereby providing a continuous arcuate surface against which the pasta is supported during discharge.

Description

~Z75~7~7 ~59~
The subject invention relates generally to dry food dispensing containers, and in particular to elongate pasta dispensers having integral portion discharging means.

Containers for storing and dispensing elongate pasta are well kno~n and find common use in household kitchens. Such containers typically provide a cylindrical canister for storing elongate pasta in an upright axial orientation, a lid for enclosing the canister and additionally adapted to function as a portion dispenser, and a dial cap rotatable mounted to the lid component. The lid is provided with at least one pro~iled aperture therethrough sized to per~it the simultaneous axial passage of a predetermined volwme of pasta therethrouqh when the canister is rotaked into a horixontal or inverted postion. The dial cap components of pasta dispensers on the market include a sized opening which can ~e rotated into a superposed alignment over the lid aperture, whereby permitting discharge of pasta. Alternatively, the cap can be ro~ated into a storage position which barriers the lid aperture to prevent inadvertent spillage of pasta.
While available pasta dispensers have been favorably received in the market, a common deficiency prevents them from achieving a satisfactory functional performance level. That deficiency resides in the shape of the sized aperture through which pasta is meted. Known apertures are shaped either trapezoidal or triangular in plan view. In either case, with the canister in the horizontal or inverted dispensing position, the quantity of pasta within the canister must far exceed the aperture volume ~or proper portion dispensing to occur. As pasta is depleted from the canis~er, the fill line defined by the remaining pasta migrates downward relative to the horizontally disposed canister and will eventually pass the upper boundary of the lid aperture. At that point, however, the pasta volume in conventional dispensers is no longer distributed so as to fill the portion sized lid aperture~ Such is the case even though the total pasta ' ' ~27~

volume remaining in the canister exceeds the lid aperture volume. Portionment discharge by the dispenser is thereupon no longer possible and guesswork becomes necessary in order to withdraw a desired quantity of pasta from the container.

A pasta dispenser is disclosed comprising a cylindrical storage canister open at one end, a canister lid having a circular top surface, and at least one sized aperture dimensioned to axially discharge a volume of pasta therethrough. Each aperture is of a semi-elliptical shape in plan view de~ined by an arcuate bottom side positioned to promimately follow the outward curvature of the top lid surface. Each aperture is further defined by a linear top side which extends between opposite ends of the arcuate aperture side and which substantially connects opposite points of the circular top lid sur~ace. A rotatable cap is provided having a like-shaped dispensing opening for exposing and closing the lid aperture in selective fashion.
Accordingly, the fill line of the pasta in a horizontally disposed canister will migrate downward with depletion and eventually conincide with the linear top side of the lid aperture. The fill line will not pass below the upper boundary of the lid aperture until the volume of the remaining pasta is less than the volumetric size of the aperture. Pasta portion dispensing is therefore continuous until such time as substantial depletion of the pasta within the canister has occurred.
A further aspect of the-present invention is that the lid and cap are provided with outward directed peripheral rim flanges which are substantially co-planar with side walls of the cylindrical canister. Resultingly, the canister in the horizontal or dispensing position serves to colleck and to aggregate the remaining pasta so as to align with the sized cap aperture. Moreover, support of the pasta is substantially - along its entire length throughout its discharge which facilitates easy removal.

Accordingly, it is an objective of the present invention ; to provide a pasta dispenser having integral discharge means.
A further objective oE the present invention is to provide a pasta dispenser having portion discharge apertures shaped to permit free-flow of a preset volume of pasta therethrough.
Yet a further objective of the present invention is to provide a pasta dispenser having means for collecting and aggregating the remaining pasta to facilitate free and accurate portion dispensing thereof.
Still a further objective of the present invention is to provide a pasta dispenser having apertures shaped to permit - accurate portion discharge of pasta until the pasta contained by the dispensor is substantially depleted.
A further objective is to provide a pasta dispenser having integral capping means to selectively permit and inhibit discharge of pasta Erom the dispenser.
These and other objectives, which will become apparent to one skilled in the art, are achieved by a preferred embodiment which is described in detail below, and which is illustrated by the accompanying drawings.

Detailed Description of the Preferred Emobdiment Referring first to figD 1, the subject dispenser assembly 2 is shown as generally comprising three components:
a cylindrical canister body 4; a cylindrical lid component 6;
and a cylindrical cap 8. The canister 4 includes cylindrical sides 8 which define an internal cavity 12 open at a top end.
Midway along the length of the cylinder sides 10 is an outward extending peripheral flange 14.
The lid component 6 of the dispenser assembly 2 is tO provided with generally cylindrical sides 16. An outward extending rim flang 18 extends from a lower end of the sides 16. It will be appreciated that the outwarding extending 1ange 18 constitutes a handle for the purpose of removing the lid component 6 from the cylindrical canister 4. The sidewalls 15 of the lid 6 are stepped inwardly at the forward end as shown at 20. The lid 6 is further provided with a circular top surface 22 from which the stepped sides 20 project. Centrally disposed within the top surface 22 is a central assembly aperture 24. Inward ~acing surfaces 26 of the stepped sides 20 extend outward from the peripheral rim of ;~ the circular top surface 22.
As shown in Fiy. 1, two apertures 28, 30 are provided within the top surface 22 having a shape specified belo~. The apertures 28, 30 are sized having different respecti~e volumes. While only two apertures 28, 30 are shown, it will be appreciated that additional, differing sized apertures may also be provided within the top surface 22, if so desired.
The shape of each dispensing aperture 28, 30 can be understood as follows. Each aperture is defined in part by an arcuate bottom side 32 which is disposed adjacent to the peripheral rim of the top surface 22 of lid 6 and generally follows the curvature thereof. ~ linear side 34 of the ~; aperture extends between opposite ends of the curved arcuate side 32. Accordingly~ the linear side 34 is seen to represent ~ essentially a chord of the circular top surface 22 which - ` connects opposite circum~erential poi~ts thereo~. In gene~al, each of the apertures 28, 30 have a semi-elliptical shape in ' ' ~ -~Z7~

which the arcuate portion thereof proximately coincides with the curved periphery of the top surface 22. It will also be appreciated from Fig. 1 that the outward extendin~ inward sides 26 of the stepped lid portion 20 lie essentially co-planar with the arcuate sides 32 of the apertur2s 28, 30.
The cap component 8 likewise comprises cylindral sides 36 and has a circular top surface 38. A registration bead 40 ~: i5 disposed centrally of the circular top surface 28 and a peripheral rim flange 42 extends outward therefro~. A
selection aperture 44 is disposed within the circular top surface 38 and has a general shape similar to the apertures 28, 30 of the lid component 6.
Assembly of the su~ject dispenser proceeds as follows.
The canister 4 is designed to contain a volume of elongate pasta, which will be stored in an upright axial orientation.
The lid component fits closely over the open end of the cylindral canister 4 and bottoms against the peripheral flange - 14. Permanently and rotatably secured to the lid component 6 is the cap component 8. The cap component 8 rotatably fits ~` 20 over the end of the lid component 6 and rotates against the -~; inward stepped sides 20 thereof~
` Referring collectively to Fig. 1, 2, and 3, the dispenser assembly 2 is utilized as follows. The canister 4 is rotated into a horizontal configuration as shown in Fig. 1 so that the collective pasta stored inside is gathered at the bottom by the curved sides 10. The cap co~ponents 8 is thereafter rotated until the aperture 44 coaligns with either aperture 28 or aperture 30. Apertures 28, 30 are sized so as to represent the volume of pasta necessary for a specified number of portions. For example, the smaller sized aperture 28 can be sized to represent the volwme of pasta necessary for - a single serving portion and the larger aperture for amultiple serving portion. upon coalignment of the cap aperture 44 with, or example, aperture 30, the canister body 4 is further rotated into an inverted position so that -the pasta stored ` therein slides through the co-aliyned apertures.

It should be appreciated that the outward extending peripheral cap rim flange 42, the outward extending in~ard sldewalls 26 of lid 6, and the internal surfaces of the canister sides 10 are substantially co-planar. The result is that the pasta to be dispensed through apertures 30, 44 moves along a continuous arcuate surface composed by the aforementioned component surfaces. Smooth egress of the pasta through the co-aligned apertures results. Further, because of the aformentioned curved adjoining component surfaces, the pasta remains aggregated throughout its discharge from the canister body 4 in a close axial alignmentO Accurate portion discharging is thereby enh~nced.
Considering the dispenser assembly 2 in its horizontal or inverted discharge position as shown in fig. 1 and 4, it can be seen that as the pasta stored within the canister 4 is depleted, the fill line defined by the top of the remaining pasta progresses downward. The fill line is representatively shown by line A-B in Fig. 4. Fill line A-3 extends across the width of the canister and across the top surfaces 22, 38 of components 6, 8 respectively. For purposes of explanation, portion dispensing aperture 28 will be referred to.
Because of the shape of aperture 28, as the pasta fill line ~-B progresses downward, it will at some point coincide ; with the linear topside 34 of the aperture. At that point, -~ the volume of pasta remaining in the canister will substantially equal the volumetric portion of pasta represented by the aperture. Because of the collective cooperation between the curved bottom sides of the canister 4, the lid 6, and the cap 8, the remaining pasta is collected at the botto~ of the dispenser assembly and can be discharged through the aperture out pasta down to the point where the volume of pasta remaini~g in the canister 4 equals the volume -~ of the aperture 28.
In contrast with the foregoing, the prior art is shown ~- in Fig. 5~ The fill line represented by A-B is shown as extending across the top lid of the prior art dispenser assembly. The prior art lid is shown as generally comprising ' ' ' ' ':

~2~ 7 a trapeæoidal dispensing aperture 45 defined by a top arcuate boundary 46 and a bottom arcuate boundry 4~. It will be appreciated that as the fill line of A-B migrates downward through depletion, it at some point will cross the top arcuate boundry 46 of the dispensing aperture 45. Below this point, the dispenser cannot discharge an accurate portion of pasta through aperture 45 since the entire aperture must be filled in order for the user to withdraw the preselected volume of pasta. However, as shown in fig. 5, at the point when the fill line crosses over the top arcuate boundary 46 of the discharge aperture 45, a substantially greater volume of pasta than the volume of aperture 45 remains in the canister. An excess volume of pasta is therefore required in order for the prior art aperture to remain functional. That excess pasta volume is represented at 50 in fig. 5. It will ~e appreciated that after the fill line drops below the top boundary of the aperture 45 accurate discharge of pasta is not possible even though the total remaining volume of pasta within the canister may in fact exceed the volume of aperture 45.
` 20 From the foregoing, it will be appreciated that the subject invention provides a pasta dispensing assembly which is simple to manufacture and which consists of a minimal number of components. The dispenser assembly cap and lid are ` provided with apertures of a shape which enhances free movement of elongate pasta therethrough. Fur~her, the coaligning flanges of the cap7 the lid, and the cylindrical canister body insure that the pasta will be supported along its entire length through the discharge procedure. As a result, accurate and smooth egress of the pasta from the canister is facilitated. Finally, the shape of the apertures within the lid and cap component insure that the apertures continue to function to portion out volumes of pasta until the pasta within the canister is substantially depleted. This advantage is realized because the pasta fill line mus~ pass the upper linear side of each dispensing aperture, -~ substantially coextensive along its length. In contrast, the ~ prior art apertures become disfunctional prior to the point .

when the volume of remaining pasta within the canister eguals the volume of the dispensing aperture.
