    摘要: A duckbill valve is provided which includes a hollow cylindrical elastomeric body with first and second ends. The first end has walls parabolically tapering to an elongate slit, the slit being surrounded by an upper and lower lip. The second end has a non-uniformly round (e.g. oval) outer wall terminating in an open mouth. When inserted into a perfectly round apertured fitting, the non-uniformly round outer walled elastomeric body is bowed to form-fit the round configuration thereby forcing shut the lips and slit. Upon increased air pressure within the elastomeric body, the slit is forced open. In a second embodiment, the inner wall of the second end may be non-uniformly (e.g. oval) round. Insertion of a round tubular fitting within the non-round inner wall of the elastomeric body also achieves a bowed form-fit configuration which forces shut the lips and slit.

    摘要: An applicator pad dispensing container is provided having a jar, a cap to close the jar and a piston assembly movable within the jar. The piston assembly includes a platform with a rod projecting from an upper surface thereof terminating in a head. A stack of applicator pads, each with a central aperture, can be loaded onto the platform with the rod penetrating the aperture to securely hold the pads. The head engages a hollow socket in an under surface of the cap. Engagement of head and cap allows the platform with pads to be raised to a top position whereupon the cap can twistably be released from the head. After a pad(s) is removed, the cap can snap onto the head and with downward pressure return the platform with remaining pads back into the jar.

    摘要: A reclosable dispenser is provided which includes a receptacle, preferably a unitarily molded plastic thermoform, for holding dry goods such as cotton swabs and a reclosable lid hingedly attached to the receptacle. The lid has a cover substantially co-extensive with the open top of the receptacle and includes a cover with a flap extension at an end thereof oriented perpendicular to the cover. A slot in the flap extension lockingly receives a rigid tab formed along a flange atop a front wall of the receptacle. The tab and slot arrangement allows for easy opening but secure closure of the dispenser.
