A liquid dosing device for a container includes a dosing chamber having a front end and a back end. An outlet passage is located at the front end. A plunger is located in the dosing chamber, divides it in a front and a back space, and is moveable between a forward position in which the plunger closes off the outlet passage, and a backward position, in which the front space has a maximal volume. An inlet passage provides fluid communication between the front space and the container. A timer passage provides fluid communication between the container and the back space. A release passage, being greater than the timer passage, provides fluid communication between the back space and the container. A valve assembly at the release passage includes a valve seat located at the back end of the dosing chamber.

A dosing cap for dispensing a measured dose of material includes a housing, a sealing member and a biasing member. The housing has an inlet end residing within a container and receives the material. An outlet end dispenses the material. A dosage region is interposed between the inlet end and outlet end. The sealing member is received within the housing. The sealing member includes a first seal proximate the inlet end to selectively open or close the inlet end and a second seal proximate the outlet end to selectively open or close the outlet end. When the biasing member is unbiased, the inlet end is open, the outlet orifice is closed and the dosage region is charged with material. When the biasing member is compressed, the sealing member is biased so that the inlet end is closed and the outlet orifice is open whereby the material is dispensed.

The dose dispense closure for a squeezable container. The closure has a body cap 20 with inlet orifices 37 and a transit orifice 34 which allows composition into the body cap. A piston 80 is provided within the body cap 20. When the container is squeezed, the piston 80 is forced down, thereby expelling liquid from a control cap 40 until the piston 80 lands on the end of a duct 60 in the control cap 40 to prevent further dispensing. When the squeezing force is removed, the piston 80 returns to its start position. The piston 80 is biased towards the end wall 33 of the body cap 20 by a compression element 87. The body cap 20 is attached directly to the container such that rotation of the body cap allows adjustment of the dosage without having to remove the body cap.

The present invention relates to an apparatus and methods of repeatedly dispensing controlled doses of liquid. In one embodiment of the present invention, the apparatus includes a resiliently squeezable container, a cap operably connected to the container, a dosing chamber operably connected to the cap, at least one timer aperture located proximal to the discharge opening, a plunger, a valve retaining means located below the base, and a valve provided in the valve retaining means. The ratio of the total surface of the inlet openings and the timer apertures is from about 2 to about 17 and the viscosity of the liquid is from about 1 to about 600 mPa.Math.s (measured at 10 s.sup.1 at 20 C.).

A dispensing closure for dispensing flowable product from a squeeze container includes a closure body having an upper deck and a dispensing orifice within the upper deck. A timing piston extends downwardly from the upper deck and is located adjacent to the dispensing orifice. The timing piston is movable between an open position wherein a flared piston neck is spaced from the dispensing orifice, and a closed position wherein the flared piston neck closes off the dispensing orifice. A timing vent within the upper deck is in communication with a piston chamber to allow air to escape the piston chamber. An air intake orifice within the upper deck allows air to enter the piston chamber, and a ball valve structure adjacent the bottom surface of the upper deck cooperates with the air intake orifice to control the flow of air through the air intake orifice.

An apparatus and means of repeatedly dispensing controlled doses of liquid contained in a resiliently squeezable container, wherein the dose size can be adjusted.

This invention relates to a device, a system and a method for applying a volume of liquid to a treatment surface. The device includes a container for containing the liquid, a pump for extracting liquid from the container, an actuator for operating the pump, and a collapsible receptacle for accommodating extracted liquid.

A large bottle has a lower region, an upper region, and an intermediate region with a cap removably positioned on the upper region. A small bottle has a lower region, an upper region, and an intermediate region with a cap removably positioned on the upper region. A coupling tube has an upper end and a lower end. The upper end is operatively coupled to the small bottle at the upper region. The lower end is operatively coupled to the large bottle at the lower region. A long web attaches the coupling tube to the large bottle. A short web attaches the coupling tube to the small bottle. A display panel removably receives and supports a plurality of large and small bottles.

A dual chambered dispensing bottle that utilizes gravity and bottle geometry to precisely dose a desired amount of a liquid.
