  • Patent number: 8627987
    Abstract: A container, for example for a food product or the like, provides an elevating lower inner surface that may sealably support a contained food product to raise the upper surface of the food product as it is consumed. Importantly, the container avoids an extension of the elevating mechanism into the product itself, reducing problems of contamination and leakage.

  • Publication number: 20090324320
    Abstract: A porous applicator for skin sealant has a container of skin sealant held within the applicator. When the skin sealant is released, it flows to a dispensing end of the applicator. The dispensing end has a slot through which the skin sealant is dispensed, however, a roller is rotatably held within a portion of the slot. The roller is porous, in that it has at least one, and desirably a plurality of openings formed through the roller. The skin sealant flows through the slot and through the opening(s) in the roller, so that when the roller is stroked against a patient's skin, the skin sealant is uniformly dispensed on a patient's skin. Pressure applied by a user when applying the skin sealant on a patient's skin does not result in abrasions on the patient's skin from the dispensing end of the applicator.

  • Patent number: 7261485
    Abstract: An integrated delivery device that is both a container and an applicator for small quantity of fluids is disclosed. The integrated delivery device is particularly suitable for viscous substances. The integrated delivery device comprises of two slidably engaged sections with matching concave and convex surfaces wherein a small quantity of viscous fluid is enclosed between the two sections. When the two sections are urged toward each other, the small quantity of viscous fluid between the two sections is urged to exit through a channel in one of the two sections. The two sections will mate to form an integrated applicator that can be used to apply the extracted viscous fluid.

  • Patent number: 6776549
    Abstract: A device for applying a product defines a height and includes a first compartment defining a reservoir for containing a product. The first compartment may include a variable volume. The device may include a second compartment defining an opening and being in one of selective and permanent flow communication with the first compartment via at least one orifice. The second compartment may be configured to at least partially receive an applicator for applying the product, and may define a volume which is substantially fixed. The device may include a closure element configured to close off the opening of the second compartment. The device may be configured so that the height of the device diminishes as the volume of the first compartment becomes reduced, and at a last use of the device, the axial height of the device may be less than the axial height of the device at a first use of device.
