Definitions

• TECHNICAL FIELD This invention relates generally to dispensers and, more specifically, to loose fill dispensers that include child safety features.
• Loose fill dispensers are a convenient packaging format for many applications. For example, loose fill dispensers are useful for dispensing candy, mints, gumballs, and other loose fill items. Loose fill dispensers are also useful for users that get prescriptions filled since the dispensers are refillable and reusable.
• loose fill dispensers are not configured to provide a unit dose. Rather, the user is required to pour out a quantity of the items contained therein and return the excess amount to the container. Thus, it is desirable to have a loose fill dispenser that dispenses a unit dose. What is needed is a loose fill dispenser that is easy to operate, includes child resistant features, and is configured to dispense a unit dose.
• a dispenser that includes an improved dispensing cap.
• the improved dispensing cap is received in and attached to an open end of a container of loose fill items.
• the dispensing cap includes a measuring compartment that is configured to receive an item or quantity of items from the loose fill container of the dispenser.
• the dispensing cap also includes a moving or rotating portion with an attached fin or wedge element. This fin can be inserted into the measuring compartment to contact, isolate, and dispense the quantity of items. Further the fin blocks additional items from entering the measuring compartment.
• a dispenser includes a dispensing cap that is secured to the open end of a container.
• the dispensing cap includes a base portion that defines a compartment or chamber in which an item or quantity of items from the container can be received.
• a rotating portion is pivotally attached to the base portion.
• the rotating portion includes an ejecting fin that is dimensioned and positioned to be inserted into the compartment, to contact and isolate an item that is received in the compartment, and to move the item toward or through an open end of the compartment.
• the rotating portion also includes a cover portion.
• the cover portion is positioned to cover, close, or obstruct the open end of the compartment as items are aligned in a path and urged into the compartment.
• the cover portion is removed from the open end of the compartment as the rotating portion is rotated to provide an opening through which the items in the compartment can exit the compartment. Since the cover portion and the ejecting fin are integral to the rotating portion, the ejecting fin is inserted into the compartment, the cover portion is removed from the open end of the compartment, and the item or quantity of items is dispensed from the compartment in a single action.
• the exemplary dispenser includes a safety feature or mechanism that prevents the rotating portion from freely rotating or otherwise fixes the position of the rotating portion.
• the exemplary safety feature is a cantilever that contacts an edge of the dispenser. To release the safety feature, the cantilever can be deflected inwardly to be displaced fro the edge of the dispenser and thereafter the rotating portion can rotate and the dispenser can be operated.
• the compartment is at least partially defined by a separation wall, which is offset from a side wall of the container and extends between front and back walls of the container.
• the exemplary separation wall extends into the container to define a path that precedes or leads to the compartment.

• the dispenser cap 14 can be assembled as the rotating portion 42 is received in the open end 60 of the base portion 40. Specifically, the axial protrusions 98 are received in respective apertures 78. Thereby, the rotating portion 42 is pivotally connected to the base portion 40.
• the dispensing cap 14 can be assembled with the container 12 as the lower portion 62 of the base portion 40 is received in the open end 30 of the container 12.
• the lower portion 62 of the base portion 40 is inserted into the open end 30 of the container 12 until the edge E1 at the open end 30 of the container 12 contacts the edge E2 of the base portion 40 and the detents 68 are received in the apertures 32.
• the dispensing cap 14 is thereby secured to the container 12 to form the dispenser 10.

• the cover portion 112 of the lever 90 provides the means for opening and closing the dispensing open end 59 of the measuring compartment 74. Specifically, when the lever 90 is in the closed position, the cover portion 112 closes, obstructs, or covers the dispensing open end 59 of the measuring compartment 74. When the lever 90 is rotated, the cover portion 112 is displaced to uncover the dispensing open end 59 of the measuring compartment 74.

Specifically, the free end of the safety cantilever 114 is obstructed by or contacts the edge E3 of the open end 60 and the cover portion 112 is obstructed by a top edge of the separation wall 70 (best shown in FIG. 2). Thus, the rotating portion 42 is constrained or otherwise substantially unable to rotate relative to the base portion 40. Further, in the closed position, the detents 100 are releasably engaged in respective retaining apertures 80 to additionally secure the rotating portion 42.
• the dispenser 10 is operable to measure and dispense the tablets 16 one at a time.

The tablet 16 is urged along the path, through the opening 57, and into the measuring compartment 74. The tablet 16 can then be dispensed by the dispenser 10 with a single pivotal action after the safety feature is released or operated.
• the safety cantilever 114 is deflected inwardly. While the safety cantilever 114 is deflected inwardly, the contact portion 110 is pressed into the rotating space 76 to dispense the tablet 16. The rotating portion 42 is thereby rotated about the axis defined by the apertures 78 and axial protrusions 98 such that the cover portion 112 rotates from the open end 60 of the base portion 26 to form an opening through which the tablet 16 can exit the dispenser 10. Simultaneously, the ejecting fin 92 rotates through the slots 84, 86 and is inserted into the measuring compartment 74 such that first edge 94 of the ejecting fin 92 contacts and isolates the tablet 16.
• the tablet 16 is thereafter dispensed from the measuring compartment 74 through the opening.
• the second edge 96 of the ejecting fin 92 obstructs additional tablets 16 from entering the measuring compartment 74 such that only the tablet 16 in the measuring compartment 74 is dispensed.
• the rotating portion 42 provides means for inserting the wedge element or ejecting fin 92 into the measuring compartment 74 such that the leading edge 94 of the ejecting fin 92 rotates into the measuring compartment 74.
• means for inserting the wedge element into the measuring compartment can include a moving portion such that the leading edge of the wedge element slides or translates into the measuring compartment.
• the tablet 16 before the tablet 16 is aligned in the path defined by the separation wall 70 or through the opening 57, the tablet 16 must be properly oriented within the dispenser 10.
