Technology Field

Aspects of the present invention are directed to a variable dose applicator having a collar portion for dispensing the contents of a container to allow a user to select the amount of contents to be dispensed.

Background

Containers with pumps provide a hygienic and convenient way to dispense contents contained within the container. Such containers are readily used with pharmaceuticals, cosmetics, and the food industry. Typically, a user presses down on an actuator or button, which enables the pump within, and a predetermined amount of contents is dispensed.

In a conventional container, the amount of contents that is dispensed is constant every time the user presses down on the actuator because the piston travels the same distance with each pump. It is difficult for a user to manually control the distance that the piston is moved when pressing the actuator. Thus, regardless of the amount of contents that is needed by the user, the same amount is always discharged from the container. A user is not able to select and customize the amount of contents that is dispensed from the container which results in waste and an inconvenient user experience.

Containers that may allow for varied dosing are often bulky and complicated in construction. Additionally, such containers can involve many individual parts and can be expensive to manufacture resulting in an increased end cost for the user.

Based on the concerns noted above, a variable dose applicator with a simple construction that easily allows a user to select the amount of contents to be dispensed and applied directly to the intended area is highly desirable.

Aspects of the present invention are directed to a variable dose applicator comprising: a container including a collar portion, a top portion, a bottom portion, and a side wall portion, the space between the bottom portion and the side wall portion defining an interior space to store contents, and an actuator coupled with the container, the actuator being depressible in a longitudinal direction to drive the contents held in the interior space of the container out of an applicator extending from the actuator, wherein the actuator includes one or more dosing elements protruding horizontally from the actuator, and wherein the collar portion has a top circumferential edge containing one or more grooves of varying depth into which the one or more dosing elements can be inserted when the actuator is depressed, thereby adjusting a distance the actuator is moved in the longitudinal direction.

The present invention further provides that the one or more dosing elements protrude from the actuator in a direction perpendicular to the actuator. The present invention further provides that the actuator is rotatable to align the one or more dosing elements above the one or more grooves.

The present invention further provides that the container includes a shoulder. The present invention further provides that the collar portion is a hollow circular shape and is provided on the shoulder. The present invention further provides that a top end of a tube extends into the collar portion and a bottom end of the tube extends to the contents held in the interior space of the container.

The present invention further provides that the one or more grooves includes a high dose dispensing groove having a depth between about 2.0 mm and about 5.5 mm. The present invention further provides that the high dose dispensing groove has a depth of about 3.1 mm. The present invention further provides that the one or more grooves includes a low dose dispensing groove having a depth between about 0.1 mm and about 3.1 mm. The present invention further provides that the low dose dispensing groove has a depth of about 0.8 mm. The present invention further provides that the high dose in in an amount between about .5 mg and about 10 mg. The present invention further provides that the low dose is in an amount between about 0.5 mg and about 3 mg.

The present invention further provides that the contents stored in the interior space of the container is docosanol. The present invention further provides that the contents stored in the interior space of the container is a combination of docosanol, benzyl alcohol, light mineral oil, propylene glycol, water, sucrose distearate, sucrose stearate.

Detailed Description

Aspects of the present invention are directed to a variable dose applicator having one or more dosing elements on an actuator, a pump for dispensing a contents of the variable dose applicator via an applicator, and a collar portion to allow a user to select the amount of contents to be dispensed and applied directly to the intended area. The collar portion of the variable dose applicator is equipped with grooves of varying depth so that the operating distance to which the actuator is moved to discharge the contents can be adjusted to control the amount of contents that is discharged without changing the functionality of the inner pump. The greater the depth of the groove, the lower the actuator can be depressed by a user resulting in more contents being dispensed from the container. A user can position grooves of a desired depth under the dosing elements, thereby when the actuator is depressed, the groove creates a mechanical stop preventing the actuator from being depressed further than the intended amount. Thus, a user can select the amount of contents to be dispensed from the container.
