DETAILED DESCRIPTION
It should, of course, be understood that the description and drawings herein are merely illustrative and that various modifications and changes can be made in the structures disclosed without departing from the present disclosure. Referring now to the drawings, wherein like numerals refer to like parts throughout the several views, FIGS. 1 and 2 illustrate an exemplary product dispenser 100 according to the present disclosure. The product dispenser 100 generally includes a body 102 having an upper wall 104, a lower wall 106, and a side wall 108. The upper and lower walls 104, 106 can be integral with the side wall 108 or can be separate parts that are fixedly secured to the side wall 108. A divider 110 extends between the upper and lower walls 104, 106 and together with the walls 104, 106, 108 of the body 102 defines separate first and second compartments 116, 118 for holding associated products. The upper wall 104 includes first and second dispensing openings 120, 122 in communication with the respective first and second compartments 116, 118 (see FIGS. 3-4). The lower wall 106 includes first and second fill openings 126, 128 in communication with the respective first and second compartments 116, 118. First and second plugs 130, 132 are removably fitted in the respective first and second fill openings 126, 128. According to one aspect, the first plug 130 is configured to fit only in the first fill opening 126 and the second plug 132 is configured to fit only in the second fill opening 128. This prevents any product that may be caught on the first plug 130 from being mixed with product located in the second compartment 118 and vice versa. Also, the use of the differing first and second plugs 130, 132 ensures that proper products are provided in the first and second compartments 116, 118. A protective sleeve 134 can be secured over the side wall 108; although, this is not required.
As will be described below, the upper wall 104 is configured to have operable connected thereto a valve assembly 140 and is further configured to have mounted thereon a support 142 for the valve assembly.

With reference back to FIGS. 1 and 2, the exemplary product dispenser 100 further includes a selector 450 mounted to the upper wall 104 so that it is positioned between the body 102 and the support 142. The selector 450 is operably connected to the valve assembly 140 and is configured to move the valve assembly 140 from the closed state to one of the first opened state and the second opened state. The features of the selector 450 are best depicted in FIGS. 9 and 10. The selector 450 is defined by a wall 452 having a ring-shape and including an outer surface 456 and an inner surface 458. Located on the outer surface is a protrusion 460 (e.g., a finger grip) sized to allow a user to easy move the selector 450. The inner surface 458 includes an inwardly extending shelf 464 having first and second spaced cutouts 468, 470, first and second spaced tabs 474, 476 located beneath the shelf 464, and a third tab 480 located above the shelf and equally spaced between the cutouts 468, 470. The third tab 480 is aligned with the outer protrusion 460.
To mount the selector 450 to the body 102, the upper wall 104 is further provided with spaced sixth and seventh support walls 490, 492 which are located at a periphery of the upper wall 104. As depicted in FIGS. 3 and 4, the sixth support wall 490 is positioned between the first support wall 380 and the fourth support wall 420 and includes a ledge 494. The seventh support wall 492 is positioned between the second support wall 382 and the fourth support wall 420 and includes a ledge 496. The selector 450 is positioned atop the ledges 418, 440, 494, 496 of the respective support walls 416, 420, 490, 492. The ring 322 of the support 142 is positioned atop the wall 452 of the selector 450 (see FIG. 15).
A separate cover is mounted atop the support 142 for covering the valve assembly 140. As depicted in FIG. 12, the cover 500 includes a top wall 502 having first and second groups of holes 506, 508 (which communicate with the respective first and second dispensing opening 120, 122 via the first and second tubular members 148, 150) and a side wall 510. It should be appreciated that when used as a condiment shaker, the hole patterns on the cover 500 are specific to the condiments (e.g., 3 holes for salt, 5 holes for pepper). An inner surface 514 of the side wall 510 includes notches 516 which receive connecting tabs 520 provided on the support 142 (see FIG. 7). The inner surface 514 is further provided with locating ribs 526 that abut end walls 530, 532 of the ring 322 (see FIGS. 5 and 7). Depending from the top wall 502 and surrounding the holes 506, 508 are respective first and second frustoconical members 540, 542. As shown in FIG. 15, the first and second frustoconical members 540, 542 are received in the upper mounting rings 158, 160 of the respective first and second tubular members 148, 150. As depicted in FIGS. 1 and 2, a separate cap 550 is mounted atop the cover 500, and includes third and fourth groups of holes 552, 554 corresponding to the respective first and second groups of holes 506, 508. It should be appreciated that the selector 450, cover 500 and cap 550 can be easily modified to accommodate the first and second tubular members 148′, 150′ of FIGS. 16 and 17 without departing from the present disclosure.
According to the present disclosure, movement of the selector 450 in a first direction from the closed state of the valve assembly 140 moves the valve assembly 140 toward the first opened state, and movement of the selector 450 from the closed state of the valve assembly 140 in a second direction opposite the first direction moves the valve assembly 140 toward the second opened state. Further, the movement of the selector 450 in both the first and second directions is a rotational movement about a center axis of the body 102. With reference to FIGS. 13 and 14, in the closed state of the valve assembly 140, the third tab 480 is aligned with an indicator 560 extending outwardly from a face wall 562 of the support 142 located between the end walls 530, 532 of the ring 322. The first and second pinch arms 200, 202 are operably connected to the selector 450, which is configured to engage the fingers 250, 290 of the distal end portions 246, 286 of the engaging portions 210, 212 via the respective first and second tabs 474, 476. In this closed state of the valve assembly 140, each of the first and second tubular members 148, 150 are compressed or pinched by the engaging portions of the respective first and second pinch arms 200, 202. Movement of the selector 450 in the first direction from the closed state of the valve assembly 140 moves the valve assembly 140 toward the first opened state, wherein the engaging portion 210 of the first pinch arm 200 is solely moved away from the first tubular member 148. In the first opened state, the indicator 560 is received in the second cutout 470 of the selector 450 which maintains this position of the selector against the biasing force of the biasing member 300. Product can be dispensed from the first compartment 116. Movement of the selector 450 in the second direction from the closed state of the valve assembly 140 moves the valve assembly 140 toward the second opened state, wherein the engaging portion 212 of the second pinch arm 202 is solely moved away from the second tubular member 150. In the second opened state, the indicator 560 is received in the first cutout 468 of the selector 450 which again maintains the position of the selector against the biasing force of the biasing member 300. Product can be dispensed from the second compartment 118.
As is evident from the foregoing, a method of selectively dispensing one of a first product and a second product held in separate first and second compartments 116, 118 defined in a body 102 of a product dispenser 100 comprises providing a valve assembly 140 in the shaker body, the valve assembly 140 having a closed state closing each of first and second dispensing openings 120, 122 in communication with the respective first and second compartments 116, 118, a first opened state opening only the first dispensing opening 120, and a second opened state opening only the second dispensing opening 122; providing a selector 450 mounted to the body 102 and operably connected to the valve assembly 140, the selector 450 configured to move the valve assembly 140 from the closed state toward one of the first opened state and the second opened state; and moving the selector 450 in one of a first direction to move the valve assembly 140 from the closed state toward the first opened state, and a second direction opposite the first direction to move the valve assembly 140 from the closed toward the second opened state.
The exemplary method further comprises compressing each of the first and second tubular members 148, 150 to close off each of the first and second dispensing openings 120, 122 in the closed state of the valve assembly 140; compressing only the second tubular member 150 to close off the second dispensing opening 122 in the first opened state of the valve assembly 140; and compressing only the first tubular member 148 to close off the first dispensing opening 120 in the second opened state of the valve assembly 140.
By way of example, assuming salt and pepper are the products stored in the respective first and second compartments 116, 118, to shake salt, the selector 450 is pushed toward the first compartment 116 and to shake pepper, the selector 450 is pushed toward the second compartment 118. When the selector 450 is pushed toward either compartment, there can be a click sound (via the indicator 560 received in one of the first and second cutouts 468, 470 of the selector 450) indicating that the selector 450 will stay in place while the consumer shakes the salt or pepper. When the selector 450 is in a middle position (i.e., the closed state of the valve assembly 140), the first and second tubular members 148, 150 are completely closed/sealed off by the first and second pinch arms 200, 202 which can prevent any mess or humidity from getting inside the compartments 116, 118. Particularly, in the closed state of the valve assembly 140, both of the first and second tubular members 148, 150 are pinched closed via the engaging portions 210, 212 of the first and second pinch arms 200, 202. When the selector 450 is pushed to the salt side, the first pinch arm 200 moves out of engagement with the first tubular member 148 in communication with the first compartment 116, while the second pinch arm 202 remains engaged with the other tubular member 150. When the selector 450 is pushed to the pepper side, the second pinch arm 202 moves out of engagement with the second tubular member 150 in communication with the second compartment 118, while first pinch arm 200 remains engaged with the other tubular member 148.
It will be appreciated that the above-disclosed and other features and functions, or alternatives or varieties thereof, may be desirably combined into many other different systems or applications. Also that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
