Abstract: A liquid material dispenser includes a housing formed with a reservoir for the liquid to be dispensed, an outlet through which the liquid is to be dispensed, and a connecting passageway between the reservoir and the outlet. A diaphgram is located in a cavity in the passageway such that one side of the diaphragm defines a pumping chamber, and the other side defines a control chamber. An electrolytic cell generates a gas to the control chamber according to the quantity of electrical current passed through the electrolyte, for driving the diaphragm through forward strokes to pump liquid to the outlet; and a slow-acting vent vents the gas from the control chamber to the atmosphere at a rate lower than that of generation of gas by the electrolytic cell, for driving the diaphragm through return strokes to refill the pumping chamber.

Abstract: A device for packaging and dispensing a liquid or semi-liquid substance includes a receptacle suitable for containing the substance. The receptacle has a substance outlet orifice fitted with a pump including a valve suitable for enabling the substance to be delivered without ingress of air. The receptacle also includes a bottom wall constituted by a bag that defines a space inside the receptacle and contains the substance. The bag is capable of moving inside the receptacle in response to the substance being delivered so as to reduce the volume of the space and to ensure that the substance stored inside the receptacle does not come into contact with air. A margin at one end of the bag is fixed to the receptacle and the bag is suitable for deforming so as to reduce the space until the bag coincides substantially with the inside shape of the receptacle. The bag is made of a material that is elastically deformable.

Abstract: A liquid dispensing device and the method of dispensing liquid are disclosed. The device is uniquely suited to meet the requirements of hospitals and other institutions for long shelf life in inert-condition and ready activation when needed. The device includes a hollow gas- and liquid-tight casing (preferably spherical or cylindrical), a flexible gas- and liquid-tight membrane disposed entirely across the casing interior dividing the interior into a propellant chamber and a liquid chamber; an outlet port from the liquid chamber; two mutually reactive chemicals in the propellant chamber but separated by a barrier; and a member to breach the barrier and permit the chemicals to come into contact; the two chemicals being reactive upon contact to form a propellant gas. The propellant gas thereupon expands against the membrane, moves the membrane to enlarge the propellant chamber, decrease the liquid chamber, and expel the contained liquid from the liquid chamber through the outlet port. The barrier may be breached in any convenient manner, as by breaking a frangible barrier or perforating a perforable one. Preferably at least one of the chemicals is in liquid form, and one is a Group I or II metal carbonate or bicarbonate while the other is an acid, acid anhydride or acid salt; the most preferred combination is sodium carbonate and citric acid.

Abstract: A liquid material dispenser includes a rigid housing having a flexible partition defining first and second compartments on opposite sides of the partition, and an electrolytic cell in the first compartment capable of generating a gas when energized by a source of electric current in order to expand the first compartment and thereby to contract the second compartment. The second compartment contains the liquid material which is dispensed via a discharge opening in accordance with the rate of generation of the gas.

Abstract: A delivery device for delivering a liquid containing a drug includes a first diaphragm within a housing defining a first contractible-chamber on one side of the diaphragm for holding a supply of the liquid to be delivered, and a second contractible chamber on the opposite side of the diaphragm including an electrolytic cell capable of generating a gas according to the electrical current passed through the cell electrolyte. The device further includes a second diaphragm, a control valve, and a spring, for compensating the rate of delivery of the liquid for variations in ambient pressure and temperature.

Abstract: A pressurized thin walled expandable can from which a fluent pressurized product is dispensed is made from an expandable can wall and a barrier, which may be a fully evertable bag having uniform thickness and flexibility and shaped to fit within the can wall. The open end of the bag is mounted to the can wall by apparatus which maintain a seal as the can wall expands and returns to its unexpanded condition. As product to be dispensed is introduced into the product chamber, the flexible bag is extended down into the lower end of the can. As the product is later expelled through a discharge opening, the flexible bag, which may be plastic, is fully everted into the upper end of the can to expel all the product. The can is thin walled, so that when pressurized, the can diameter expands by at least one one-thousandth (1/1000) of its unexpanded value. In one embodiment, the bag is mounted by a ring inside the can. The ring includes a portion which expands to maintain the seal with the expanding can side wall. In another embodiment the ring is rigid, but of slightly larger diameter than the can. This ring stretches the can, so as to maintain the sealing contact with the can as the can expands. In other embodiments, the bag may be mounted by a stretchable adhesive and, if the bag is slightly elastic, it may be mounted by an adhesive or by a melt seal process such as heat sealing.
Abstract translation: 加压的薄壁可膨胀罐，从其分配流体加压产品由可膨胀的罐壁和阻挡层制成，其可以是具有均匀厚度和柔性并且成形为适合于罐壁内的完全可翻转的袋。 袋的开口端通过在罐壁膨胀并恢复到其未膨胀状态时保持密封的装置安装到罐壁上。 当待分配的产品被引入产品室时，柔性袋向下延伸到罐的下端。 随着产品随后通过排放口排出，可以是塑料的柔性袋完全旋入罐的上端以排出所有的产品。 罐是薄壁的，所以当加压时，罐直径膨胀其未膨胀值的至少1/000（1/1000）。 在一个实施例中，袋由罐内的环安装。 该环包括膨胀以保持与膨胀罐侧壁的密封的部分。 在另一个实施例中，环是刚性的，但直径略大于罐。 该环延伸罐，以便随着罐膨胀而保持与罐的密封接触。 在其他实施例中，袋可以通过可拉伸粘合剂来安装，并且如果袋稍微弹性，则其可以通过粘合剂或通过诸如热封的熔体密封过程来安装。
