Patent Application
20130079735
Today's spot-on applicators do not fully satisfy consumers who want to keep their hands clean, effectively apply the formulation (e.g., insecticides) to their pets' skin, and confidently apply the complete dose of formulation. There are also toxicity concerns regarding the application of insecticides, which make methods that do not require direct human contact with the insecticides more attractive.
Given these consumer needs, some advantageous features for an applicator would include 1) protection of the user's hands from inadvertent exposure to the formulation (e.g., an insecticide) during any stage of the application; 2) easy opening of a formulation container, such a disposable cartridge; 3) effective application of the formulation onto the animal's skin, despite the animal's fur; and 4) easy disposal of the formulation container. Another advantageous feature would be a way to provide feedback upon delivery of the full dosage, so the operator is confident that application is complete.
There is a need in the art for a new spot-on applicator that satisfies these consumer demands. The present invention satisfies these and other needs.
In certain embodiments, the present invention provides a device for applying a formulation to the skin. As such, in one embodiment, the present invention provides a device comprising:
In another embodiment, the present invention provides a device for applying a formulation to skin, the device comprising:
In certain aspects, the present invention sets forth improvements over prior art thermoform-disposable dispensers, including hands-free cracking open of the disposable cartridge comprising the formulation, low effort dispensing of the formulation, a “fur parter” that allows the formulation (i.e., the fluid or powder) to be more accurately placed on the skin layer of the pet, and hands-free removal of empty cartridge. Advantageously, it is an ergonomically friendly device that offers increased differentiation between the dog and the cat formulas. Moreover, it creates a barrier to help prevent the dispensed formulation from getting on the operator's hands.
In certain aspects, the device provides a visual indicator showing fluid level. In certain aspects, it provides audible signals during dispensing, such as a sound indicating that a specified portion of the formulation has been dispensed (e.g., a click upon completion).
These and other embodiments will become more apparent when read with the detailed description and figures that follow.
The terms “a,” “an,” or “the” as used herein not only includes aspects with one member, but also aspects with more than one member. For example, an embodiment including “an insecticide and a conditioner” should be understood to present aspects with at least a second insecticide, at least a second conditioner, or both.
The term “about” as used herein to modify a numerical value indicates a defined range around that value. If “X” were the value, “about X” would generally indicate a value from 0.95X to 1.05X. Any reference to “about X” specifically indicates at least the values X, 0.95X, 0.96X, 0.97X, 0.98X, 0.99X, 1.01X, 1.02X, 1.03X, 1.04X, and 1.05X. Thus, “about X” is intended to teach and provide written description support for a claim limitation of, e.g., “0.98X.” When “about” is applied to the beginning of a numerical range, it applies to both ends of the range. Thus, “from about 10° to 25°” is equivalent to “from about 10° to about 25°.” When “about” is applied to the first value of a set of values, it applies to all values in that set. Thus, “about 1°, 5°, or 10°” is equivalent to “about 1°, about 5°, or about 10°.”
In formulations comprising an “additional,” “further,” or “second” component, the second component as used herein is chemically different from the other components or first component. A “third” component is different from the other, first, and second components, and further enumerated or “additional” components are similarly different.
The term “or” as used herein should in general be construed non-exclusively. For example, an embodiment of “a formulation comprising A or B” would typically present an aspect with a formulation comprising both A and B. “Or” should, however, be construed to exclude those aspects presented that cannot be combined without contradiction.
Generally, when a range is taught, it incorporates all full or partial amount in between the endpoint (i.e., within the bounds of the range). For example, a range of 5° to 35° would also teach inter alia the specific values of 8.47° and 23°. A range of about 10° to 25° would also teach inter alia the specific values of 14.13°, 18°, and 21.1°.
In one embodiment, the present device creates a barrier to help prevent or reduce liquid from getting on hands; optionally notifies the pet owner when application is complete (e.g., by an audible signal or visual indicator); parts hair to help the formulation gets down to the skin (e.g., by use of a fin to part the hair or fur); has a contemporary design; is ergonomically contoured for easy handling; is sturdy and secure in hand; has a better grip; and has a re-closable packaging for storage.
In one aspect, the device comprises a spreading means 101, wherein the spreading means is operably connected with the top of the housing 104 or cartridge; wherein during use, the spreading means moves or spreads a plurality of the skin's epidermal growths. The device has a right side and a left side of the housing, making it easy to pick up the lid 104 of the housing.
In other embodiments, the tab has at least two projecting prongs. In other aspects, at least one prong, tine, or tooth of the spreading means comprises an angled tip. In other aspects, at least one prong, tine, or tooth has a U-shaped cross-section. In other aspects, at least one prong, tine, or tooth is cylindrical. In other aspects, the spreading means extends from the housing at a non-zero angle. In still other aspects, the non-zero angle is from 1° to 45°. In other aspects, the non-zero angle is from 5° to 35° or from 10° to 25°.
Turning now to an embodiment shown in
In one embodiment, the device's chamber is composed of a flexible, deformable material so that the chamber can be squeezed to apply pressure on the cartridge to facilitate release of the formulation from the cartridge. In certain instances, the ejecting means ejects the cartridge without the user's touching of the cartridge or formulation.
In one embodiment (e.g.,
In certain aspects, the present invention sets forth a dispensing means that is a roller-ball tip dispenser. As the dispenser tip moves over the surface, it dispenses the formulation onto the skin or surface. If the dispenser tip stops moving, it stops dispensing the formulation. In some aspects, the invention further sets forth a spreading means that is a V-shaped trough or fin style projection that parts the hair and exposes skin for application of the medication. In some embodiments (e.g., those shown in the figures), the device includes a lip that acts to spread the fur or hair, thereby facilitating the application of the fluid to the skin. In some aspects, movement is from tail to head “against” natural hair growth direction to allow easier spreading.
In certain aspects, different medications are color-coded to prevent misapplication. In certain aspects, cartridges for different formulations are different shapes or sizes to prevent misapplication. For example, an embodiment set forth in the figures have cartridges that are different shapes to prevent a cartridge intended only for use with an animal (e.g., a dog) from being used in a dispenser designed for a second animal (e.g., a cat). This can advantageously deter negligent misapplication of medications that would be toxic to the second animal.
As mentioned, differences in cartridge design advantageously allow easy differentiation of dog and cat formulations. In one embodiment of a dog formulation, this differences include a unique or easily distinguishable packaging; a unique or easily distinguishable applicator with a rounded shape for the applicator and thermoform cartridge; and an added “DOG” embossed on applicator and thermoform.
In one example of a cat formulation, the differences include a unique or easily distinguishable packaging; a unique or easily distinguishable applicator with a squared shape for applicator and thermoform; and an added “CAT” embossed on the applicator and thermoform.
In certain instances, the applicator device and thermoforms are clearly marked and colored coded to help prevent misapplication between species and animal size. In one aspect, a dog thermoform will not work in a cat applicator and vice versa. The applicator helps create a more controlled, reliable application. It also helps prevent or reduce getting liquid on the operator's hands, and it aids in getting the applied formulation down to the skin.
In some aspects, the dispenser may be color-coded to prevent misapplication or for easy identification of the proper cartridge for use. In some aspects, the color of the movable top piece may be purple, burgundy, or red, and the remainder of the device may be black, dark gray, or light gray. Alternatively, the color of the movable top piece (or door) may be red, blue, orange, or pink, and the remainder of the device may be black, dark gray, or light gray. Alternatively, the color of the movable top piece may be green or blue (preferably, green), and the remainder of the device may be black, dark gray, or light gray.
In some aspects, the lower half of the device has a texture and color similar to the top. In other aspects, the lower half's texture or color may be different (e.g., darker). In some aspects, the texture may be different (e.g., a heavy or slightly rough texture on the bottom, and a smooth texture on the top).
In one embodiment, the device optionally comprises a measuring means 206 (e.g., a window); wherein the measuring means is operably connected with the housing or cartridge; and wherein the measuring means allows the user to identify how much formulation has been dispensed. In certain aspects, the measuring means is a transparent or translucent window 206 in the housing. In certain aspects, the device further comprises a dispensing means, wherein the dispensing means is operably connected with the housing or cartridge.
For example, a triggering means 401 is shown, wherein the triggering means 401 is operably connected with the housing or cartridge.
In one embodiment, the device comprises:
