Toothbrush package
Attractiveness of consumer products is enhanced by use of scintillating fluorescent light collecting fibers contained in those products. The fibers collect ambient light of various wavelengths, some not visible, along their length which is collected within the fiber and emitted as visible light at the ends of the fibers. The emitted light can be used to enhance the consumer appeal of the product or promote its use. Specific consumer products disclosed include toothbrushes and liquid soap dispensers.
This is a continuation of International Application PCT/US2003/031821, filed Oct. 9, 2003, which claims the benefit of U.S. application Ser. No. 60/417,868, filed Oct. 11, 2002, both of which are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTIONConsumer research shows that toothbrush purchases are often based on impulse decisions. Thus, the appearance of a toothbrush and/or its packaging can play a role in formulating that purchase decision. For marketing purposes, it is also helpful for the toothbrush or its packaging to have an eye-catching appearance on the shelf. Also, use of a toothbrush, particularly by juveniles, can be enhanced if that brush has an attractive, novel appearance. Others have taken various approaches to create a visually attractive toothbrush and/or its packaging.
One such approach is illustrated in U.S. Pat. No. 4,779,173 issued Dec. 24, 1986. This patent discloses a battery operated bulb in a toothbrush handle. Light from the bulb is transmitted to the head of the toothbrush through a plurality of plastic filaments (column 4, line 64 to column 5, line 24). Another patent disclosing light from a power source, e.g. LED or laser, conveyed to a toothbrush head through fibers is U.S. Pat. No. 5,030,090.
U.S. Pat. No. 5,121,462 discloses a process for making scintillating optical fibers. U.S. Pat. No. 5,588,084 provides additional detail of the scintillation enhancement flours and wave-shifting dyes uniformly dissolved into the core material of the fiber and the cladding which serves to protect the core and enables the fiber to function as an “optical pipe”. The cladding has an index of refraction which is lower than that of the core so that the light rays are retained within the fiber's core and transported along its length to appear as visible light at the fiber ends. With scintillating fibers, the light emitted at the ends is gathered from ambient light entering the side of the fibers so that an LED and battery is not needed to generate the light emitted from the fiber ends. Another patent related to scintillating fibers is U.S. Pat. No. 6,078,052 issued Jun. 20, 2000.
U.S. Pat. No. 5,813,855 discloses an illuminated toothbrush wherein a powered light source in the toothbrush handle directs light toward cleaning elements or bristles in the toothbrush head. The bristles are illuminated by the light traveling from the source in the handle through the toothbrush handle and to the head. There it impinges on a roughened surface of the bristles embedded in the head. That light then glows from the ends of the bristles. Another lighted toothbrush is disclosed in U.S. Pat. No. 5,160,194 in which a battery operated light shines directly on the user's teeth.
SUMMARY OF THE INVENTIONThis invention utilizes scintillating fluorescent light collecting fibers to illuminate various consumer products and packaging for such products. The light emanating from the ends of such fibers is used to attract attention of the consumers to the products contained in the packaging. To the consumer, the visible ends of the fibers appear to glow as if powered, e.g., by a battery operated bulb. However, these fibers do not use any powered light sources to produce this effect. The ambient light around the fibers is gathered through the sides of the fibers and is transmitted through the fibers like an optical pipe and emanates from the fiber end as a relatively bright light.
One illustrated embodiment of this invention is a toothbrush with a transparent or translucent handle. Embedded within the handle are an array of scintillating fluorescent light collecting fibers which terminate near the base of the cleaning elements or bristles in the toothbrush head. If the fibers terminate at the base of the bristles, the light from the fibers can be distributed through all of the bristles so that the bristles adopt a glow. If a pinpoint of light is preferred, the scintillating fluorescent light collecting fibers can be placed within the bristles so that they extend to or near the working surface of the bristles. This provides a bright light display within the bristles that draws the attention of potential consumers observing the toothbrush in the store.
The light within the bristles also provides an appealing and novel appearance that would attract one to use the toothbrush, especially juveniles. Since regular use is the most important element of oral hygiene, the novelty of a lighted brush provides an important inducement and reminder for juveniles to use the toothbrush. Because the scintillating/collecting fibers are continuously collecting ambient light and displaying it through the fiber ends the novelty look of the bristles is always presented to the user or potential customer as long as there is some ambient light around the toothbrush.
A package for the toothbrush preferably has a transparent or translucent portion generally corresponding to the area of the toothbrush containing the scintillating fluorescent light collecting fibers. This allows ambient light around the package to enter the fibers and causes them to emit light at the ends of the fiber. That light shines out of the transparent/translucent portion of the package to attract potential customers who might be shopping for a toothbrush.
In other embodiments of the invention, the ends of the scintillating fluorescent light collecting fibers can be placed at various points along the length of the toothbrush (other than in the head) to create novel points of light on the toothbrush body. That lighting pattern can also be used to attract potential consumers or users.
In other embodiments, the scintillating fluorescent light collecting fibers can be embedded in the packaging of any number of consumer products, for example, a liquid soap dispenser or shampoo bottle. If that packaging material is translucent or transparent in the area of the fibers, ambient light will reach the fibers causing the ends of the fibers to emit light. That light can be used as an adjunct to graphics on the packaging, thereby attracting consumers and encouraging use after purchase.
In all of these embodiments, different color lighting can be created by colored fibers, for example, using green, amber and red fibers.
More information regarding these fibers is available from the Website of one manufacturer of such fibers, Poly-Optical Products, Inc. of Irvine, Calif. (www.poly-optical.com).
BRIEF DESCRIPTION OF THE DRAWINGS
Any suitable form of cleaning elements may be used as the cleaning elements 22 in the embodiment of
A package 24 containing toothbrush 16 is illustrated in
The term “cleaning elements” is intended to be used in a generic sense which could include conventional fiber bristles or massage elements or other forms of cleaning elements such as elastomeric fingers or walls arranged in a circular cross-sectional shape or any type of desired shape including straight portions or sinusoidal portions. Where bristles are used, the bristles could be mounted to tuft blocks or sections by extending through suitable openings in the tuft blocks so that the base of the bristles is mounted within or below the tuft block.
It is to be understood that the specific illustration of the cleaning elements is merely for exemplary purposes. The invention can be practiced with various combinations of the same or different cleaning element configurations (such as stapled or in-molded technology bristles, etc.) and/or with the same bristle or cleaning element materials (such as nylon bristles, spiral bristles, rubber bristles, etc.) Similarly, while
