Dispenser for dispensing a liquid, in particular a drug, such as for instance eye drops, which dispenser comprises two half portions which can be assembled by means of a snap lock to form a closed chamber adapted to surround a plastic bag containing the liquid, said bag having a constricted portion into which the reservoir of the bag extends, the constricted portion forming a neck with a dosage duct, through which the liquid, after breaking of the constricted portion, may be squeezed by compression of the plastic bag, one wall of the chamber of the dispenser being resilient to such an extent that the plastic bag can be compressed, and the dispenser comprising a shut off for sealing the dosage opening when no liquid is to be supplied. With the object of making the closing means open simultaneously with the compression of the dispenser for squeezing out liquid from the dispenser, the means for sealing the dosage opening are a pair of pincers formed by the two half portions, said pair of pincers being adapted to compress the constricted portion of the plastic bag close to the discharge opening of the dosage duct, at least on one of the half portions of the dispenser the pincers being extended into a ridgid tongue-shaped area of the resilient portion of the wall of the chamber and being supported for performing a seesaww motion together with the pincers when pressure is applied on the tongue-shaped area.
A food and/or treat dispenser comprises an enclosed container having at least one aperture for insertion and dispensing of food stored therein. The dispenser comprises a top portion, a base portion and a central portion therebetween, wherein at least one aperture is provided in the top or base portion. The aperture is selectively openable and returnably resilient. A plurality of ribs are provided to facilitate selective opening of the aperture. The top and base portions include a perimeter encircling a concavity, the perimeter of a relatively flat configuration so that the top and/or base portions are positionable in a free standing configuration on a flat or planar surface. The dispenser may also include a variety of means for securing the dispenser to varying objects during transport or storage.

A liquid sample storage device which utilizes a liner-holder with a liner which may be disposed of after use, thereby eliminating contamination problems associated with reusable bottles. The liner-holder is a hollow, wedge shaped container with an upwardly extending neck section and vents on the top and bottom, as well as a plurality of vents on each of its sides, to allow adequate displacement of air from within the container as the liner fills with the liquid sample. Two embodiments utilize a liner-holder which may be opened into two sections along a vertical hinge to provide access to the interior for proper positioning and later removal of the liner. The liner is positioned within the liner-holder, secured at the neck, and then suspended within the liner-holder by snap-locks or a support hook to facilitate the input of the sample into the liner.
