Abstract: A dispensing device includes a housing at least partially surrounding a compressible container. The container includes a first tab member received by a first tab receiver in a wall of the housing. The dispensing device dispenses material through an open end of the container in response to a compressive force moving an opposing end of the container towards the open end. As the container is compressed, the first tab member exits the first tab receiver and enters a second tab receiver, which is located closer to the dispensing end of the housing than the first tab receiver. The first tab member remains in the second tab receiver after the compressive force has been removed.

When the squeeze face portion (16) is compressed to the squeeze direction x, the inclined linking face portions (18) expand distance between the pair of lateral support wall portions (17) at both sides as deforming along the squeeze face portion (16) from an inclined state against the squeeze face portion (16). The inclined linking face portions (18) are restricted so as not to be flipped in the squeeze direction (x) side after deformation completes as expansion force vanishes, so that constant quantity of content liquid is discharged.

Abstract: A dispensing tip apparatus for an eye drop dispenser to administer topical ophthalmic solutions is described. The apparatus integrates an ophthalmic solution-dispensing tip with an optical gauging assembly. The tip provides continuous visual feedback about it orientation and relationship to the eye. The dispensing tip when attached to any standard topical ophthalmic solution dispensing bottle or reservoir enables the user to view a target, visually align the dispenser tip, and administer an eye drop with precision. There is also a visual feedback by which the dispenser tip is prevented from gaining too close proximity and contacting the eye, thus preventing contamination of the medication and its dispenser. The visual feedback can also contain textual or graphic information that serves as a promotional advertisement. The is assembly can be attached to the neck of an eye drop bottle or attached to the tip of an eye drop bottle.

Abstract: A container having wall portions with different pressure resistance includes a chamber with having a predetermined volume for containing an amount of fluid therein, and a mouth located at a top of the chamber and sealed by a fluid dispenser head assembled thereto. The chamber has a super-thin compressible wall of a predetermined thickness that forms a main body of the container, and two or more pressure-resistible non-deformable stiff supporting ribs located on the compressible wall at predetermined positions and having a thickness larger than that of the compressible wall.

Abstract: A self-standing type bag-shaped vacuum container has a self-standing container including a wall formed of a soft sheet, a pouring port, and a check valve mounted in the pouring port. The check valve is opened to allow the migration of a content of the container when subjected to a pressure in the pouring direction, but is closed when subjected to a pressure in a filling direction, so that the inside of the container is evacuated. The self-standing container can be optimized for storing beverages or the like which are negatively effected by contact with air, because the content will be oxidized with the air. The vacuum type container will not lose its self-standing property even if the content is reduced, and can stand stably by itself.
