This disclosure relates to a dispenser for solid or semi-solid products.
Items such as lipstick and deodorant are often dispensed in a tube or similar dispenser with a product advancing mechanism. One type of advancing mechanism is generally a screw thread including a male screw thread portion that is axially affixed but is rotatable relative to the outer package. A carrier portion is axially movable relative to the outer package but rotatably fixed to the outer package and has a complementary female screw thread. As the male screw thread is turned, the female screw thread travels in the axial direction to advance or retract the product to be dispensed from the outer package. One problem with this design is that the entire package, often much or most of which is a form of plastic or other non-biodegradable material, is designed to be disposed of once the product is consumed. Another disadvantage is that the packaging is made of inexpensive materials reducing the overall aesthetics of the package.
The above type of dispenser does not allow for a quick advancement and retraction of the product. To advance or retract the product relative to the outer package, the threaded portion must be turned multiple times.
There is a need for a dispenser that is reusable and reduces the amount of disposable packaging material while providing a more aesthetically pleasing outer package.
There is also a need to provide an outer package that is adapted to receive a refill of the product to be dispensed that can be exchanged for another product quickly and easily.
According to one aspect of this disclosure, a dispenser for a product is disclosed that comprises a handle, a slider disposed inside the handle, a cartridge defining a product receptacle, a carrier adapted to retain the product that is received in the product receptacle, and a carrier pusher connected to the carrier. An actuator is connected between the slider and the carrier pusher and is configured to advance the carrier pusher, the carrier, and the product. The actuator includes a pusher fork that extends from the slider to the carrier pusher. The pusher fork has a first set of teeth that are connected to a second set of teeth provided on the carrier pusher.

Detailed embodiments of the present invention are disclosed. The disclosed embodiments are merely examples of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale, and some features may be exaggerated or minimized to show details of particular components. The specific structural and functional details disclosed are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to practice the present invention. The terms upward and downward as used herein refer to the orientation of the drawings in the figures and should not be construed to limit the orientation of the dispenser when in use which could be any orientation.
Referring generally to the Figures, a packaging system 10, or dispenser, is disclosed in which a consumable product 12 is contained and protected in a product cartridge 14 that is adapted to be received in a dispenser housing 16 by assembling the product cartridge 14 to the dispenser housing 16.
The product cartridge 14 includes the carrier 32 and is inserted into the inner shell 34. The inner shell 34 with carrier 32 is placed into the cap 18. The consumable product 12 (hereinafter the “product”) is filled in a liquid or semi-liquid state through the central rectangular opening of the inner shell 34 and the carrier 32. The inner shell 34 is filled until the top surface of the product 12 comes into contact with the bottom surface of the carrier 32. The product 12 is allowed to cool to change to a solid or semi-solid state. An adhesive bond is created when the product 12 contacts the carrier 32. This is an efficient method of packaging the product 12 within the final package, eliminating the need for separate casting tooling and processes.
The product cartridge 14 slides into the dispenser housing 16 without changing the position of the carrier 32 and product 12 in relation to the lower shell 34 and cap 18.

The carrier 32 includes a skirt 54 disposed around the outer edge of the carrier 32. The skirt 54 is slightly larger than the surrounding interior wall of the inner shell 34. This creates an interference fit between the carrier 32 and the shell 34 and provides frictional resistance. The skirt 54 is made of an elastic material such as plastic, metal, foam or a composite of materials that allows interference between the skirt 54 and shell 34 to apply a frictional force within a range that balances the forces applied by the actuator 30 including an input force and the biasing force applied by the springs 24. The frictional force holds the carrier 32 in a fixed spatial location relative to the inner shell 34 as the drive teeth 46 slip downwardly past the carrier teeth 50.
8B show the drive teeth 46 sliding past the carrier teeth 50. The biasing force applied by the springs 24 returns the slider 22 and the actuator 30 back toward the initial state. The flexibility of the drive arms 38A and 38B allows the drive teeth 46 to slide past the carrier teeth 50. The carrier 32 remains in a fixed location relative to the inner shell by friction.
The product cartridge 14 can be removed at any time to replace the fully consumed product cartridge 14 so that the dispenser housing 16 can be provided with accept a new product cartridge 14. A partially consumed product cartridge 14 may be replaced with another product cartridge 14. For example, the product 12 may be made available in different colors or flavors. The product 12 may be made available with products 12 that provide different effects such as calming or energizing effects. The product 12 may also be made available with products 12 that provide different treatments such as treatments for dry hair or oily hair, or different skin conditions such as acne or psoriasis.
The latch 52 is configured with an angled contact area approximately 20° from the horizontal plane. This angle may be in a range of between 0° to 90° depending upon the overall requirements of the system. The upward force applied to the bottom surface of the latch 52 by the slider 22 and the angle of the latch contact area pivots the latch 52 to an unlatched position. The product cartridge 14 is released from the dispenser housing 16 and can now be removed. With the dispenser housing 16 devoid of the product cartridge 14, a new, alternate or the same product cartridge 14 can once again be loaded into the dispenser housing 16 as previously described. It should be noted that this could be done with or without the cap 18 being attached over the top portion of the product 12.
