DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the several views of the drawings, and initially FIGS. 1-3B , the product dispenser package for storing and dispensing liquid and viscous products for personal use is shown and is generally indicated as 10 .
A product dispenser package for personal use 10 is formed of polypropylene in a tube-shaped form, as seen in FIGS. 1-3B . In a preferred embodiment, the product dispenser package 10 is sized and configured for containing a measured quantity amounting to a single serving of a liquid or viscous product 12 that may be emitted via an aperture 14 located on an elongated stem 16 in communication with the top end of the container 18 of the dispenser package 10 . The liquid or viscous product 12 is stored in an interior chamber 19 within the container 18 and may be emitted therefrom by squeezing the end of the container 18 opposite of the aperture 14 using one's fingers and subsequently directing one's squeezed fingers along the length of the container 18 towards the aperture 14 , thereby forcing the product 12 stored within the interior chamber 19 into the interior channel 21 of the elongated stem 16 extending between the interior chamber 19 and the aperture 14 . The aperture 14 preferably extends nearly the entire width of the elongated stem 16 for easy and sanitary emission of the product 12 . The bottom end 25 of the container 18 is crimped or pinched and heat sealed to prevent leakage and exit of the product 12 from the bottom end 25 of the container 18 .
In a preferred embodiment, the elongated stem 16 of the dispenser package 10 is folded over on itself, preferably multiple times as illustrated in FIG. 3 , thereby pinching closed the interior channel 21 and preventing the liquid or viscous product 12 from being inadvertently emitted through the aperture 14 . The multiple fold and crease points 27 A and 27 B each define an area of closure. Accordingly, the multiple areas of closure provide a reinforced, redundant closure system to seal the dispenser package 10 closed and significantly increase the integrity of the closure to prevent leakage of the liquid or viscous product 12 . A food grade adhesive 20 is applied to portions of the elongated stem 16 of the dispenser package 10 to releasably seal together the folded segments of the elongated stem 16 , thereby ensuring the elongated stem 16 does not inadvertently unfold prior to its intended use. The seal produced by the food grade adhesive 20 can be broken by the user with the fingers when it is desired to dispense the liquid or viscous product 12 .
In one embodiment of the dispenser package 10 , a measuring marker 22 or a sequence of measuring markings 22 is included on the container 18 , wherein the product 12 is visible through the container 18 , making the amount of product 12 readily identifiable to a user, as shown in FIG. 2 . Such measuring markings 22 would be particularly desirable where the dispenser package 10 contains an amount of liquid or viscous medicine.
Referring to FIGS. 4 and 4A , an another embodiment of the product dispenser package for personal use 10 is shown, which includes a closure band 23 sized and configured for engaged receipt of the folded portion of the elongated stem 16 . The closure band 23 prevents the elongated stem 16 from inadvertently unfolding and releasing the liquid or viscous product 12 . This alternative embodiment of the product dispenser package 10 does not require the use of a food grade adhesive 20 to hold the elongated stem 16 in the folded and sealed position prior to use.
Referring to FIG. 5 , a further embodiment of the product dispenser package for personal use 10 is shown, wherein the elongated stem 16 is not foldable and includes a breakaway cap 24 adjacent to aperture 14 , for preventing inadvertent emission of the product 12 . The breakaway cap 24 is adapted to be removed by the user, with the fingers, to reveal the aperture 14 for dispensing of the product 12 .
As shown in FIG. 6 , the aperture 14 is sized and positioned to allow the product 12 to be emitted from the product dispenser package 10 without requiring that the dispenser package 10 come into contact with the object intended to receive the product 12 , such as a toothbrush, as illustrated in FIG. 7 . The small size of the interior channel 21 and aperture 14 relative to the interior chamber 19 makes squeezing the product 12 out of the aperture 14 easy and does not require that the user's fingers get close to the product 12 or aperture 14 . The small size of the interior channel 21 and aperture 14 relative to the interior chamber 19 further makes the dispenser package 10 useful for containing a range of products, such as toothpaste, mouthwash, shampoo, medicinal liquids and creams, and food items.
Referring to FIGS. 7 and 7A , yet a further embodiment of the product dispenser package for personal use 10 is shown, which includes a removable cap 26 that seals an opening 28 on container 18 that is in communication with interior chamber 19 . The removable cap 26 is reusable and, accordingly, this particular embodiment of the product dispenser package 10 is suitable for containing an amount of product 12 for multiple uses, wherein the removable cap 26 is replaced after each use until the contents are completely emptied from the interior chamber. This multi-use product dispenser package 10 is particularly useful for products such as cosmetics and other creams.
Referring to FIGS. 8-10 , a cartridge 30 having a removable top 32 is provided for storing a product dispenser package 10 . A dispenser cartridge 34 may also be provided for storing multiple dispenser packages 10 , as shown in FIG. 9 , wherein the dispenser packages 10 are accessible via an opening 36 on the dispenser cartridge 34 . A sliding door 38 is structured to be opened and closed for providing and restricting access to the opening 36 , respectively. Referring specifically to FIG. 10 , a preferred method of packaging the product dispenser package 10 is shown, wherein multiple cartridges 30 may be packaged alongside dispenser cartridges 34 for convenient accessibility.
While the present invention has been shown and described in accordance with several preferred and practical embodiments thereof, it is recognized that departures from the instant disclosure are fully contemplated within the spirit and scope of the invention as defined in the following claims and as interpreted under the Doctrine of Equivalence.
