Combined bottle and closure

The dual chamber dispenser consists of two tubular chambers each of which is connected to a pump. The pumps are self-priming and are of a type that draw the substances from the tubular chambers. There is an activator which also serves as the top of the dispenser, side view apertures, a foot for better stability and a spout that is angled for enhanced dispensing. The side view apertures allow for viewing the fill level of the tubular chambers. The pumps are of a type having an upper valve and a lower valve, with the upper valves a part of the piston's that move in and out of the pumping chambers. The valves in said pumps are positive closing by means of a biasing spring. The substances to be dispensed are maintained separate, one from the other, until the substances are dispensed.

The dual chamber tubular container is closed at one end by a crimp seal and at the other end has a dispensing opening with a dividing wall. This dividing wall is attached longitudinally to the tubular chamber sidewalls and extends from the crimp seal to the dispensing opening divider wall. The divider wall of the dispensing exit as offset from the crimp seal about 75.degree. to about 110.degree. C. and preferably about 90.degree.. This enhances the uniform dispensing of the two contained sub stances.

The dispenser is a rigid type multi-chamber, refillable dispenser where only the substance containing chambers need to be discarded and replaced. At the point of the chambers interconnecting into the upper portion of the dispensers there is a cutter to break the seal on the chambers. In operation stabilized piston rods fit into each chamber and push against pistons having a deformable upper surface to expel the substance. The refill chambers have off-center exit openings whereby the distance to the dispenser nozzle exit is minimized. The push rods are stabilized by being of a size and shape to be proximate the walls of the chambers while actuating the pistons.

Dispenser

Multi-chamber containers with a dispenser/doser portion are blow molded as a single integral piece. Each chamber can then be fitted with dip tubes with a dip tube fitment forming a seal in the transition of the container body to the dispenser/doser portion. The dividing webs in the container which form the container into multiple chambers are continued up into and through the dispenser/doser portion. The webs of the container body are of a thickness so that they flex upon a compression force being applied to the container walls. This compression force flows liquid in each chamber of the container body up through the dip tubes and into the dispenser/doser portion.

Closure

The present closure is a measuring cup closure for a bottle which has bristles on the lower peripheral edge of the measuring cup portion. The closure can have a skirt disposed outwardly from the measuring cup portion, with this skirt having threads to attach the closure to the exterior threads on a bottle. In the alternative, the measuring cup portion can have threads to mate with threads on the inner surface of the bottle. There is at least a portion of the lower peripheral edge of the measuring cup that is free of bristles.

Closure brush

A closure for a container having a dispensing nozzle include a central aperture to receive the nozzle. In one embodiment, the nozzle extends through the aperture and projects upwardly from the base cap. The base cap further includes a top wall inclined with respect to the central axis of the base cap to assist in dispensing of the contents of the container. A cap lid is hinged to the base cap by a snap hinge assembly.

A dispensing container is produced from a disposable flexible, collapsible inner container surrounded by a resilient outer container. A dispensing cap assembly is removably coupled to the outer container to define a dispensing outlet for the contents of the inner container. The dispensing cap assembly includes a cap having an outlet coupled to the inner container. The inner container is attached to a support hanger which in turn is supported by the outer container. The cap has a dispensing outlet coaxially disposed with the outlet of the inner container. A dispensing check valve is provided in the cap assembly to allow the material to be dispensed without air being drawn into the container at the end of the dispensing cycle. The contents of the inner container are dispensed by squeezing the outer container to deform the side walls and create an increased pressure within the outer container causing the contents to be expelled through the dispensing check valve. The side walls are then allowed to relax which draws air into the container through air inlet check valve. The support hanger includes a depending skirt extending about midway into the outer container. The inner container is attached to the lower end of the skirt and at the upper end of the hanger.
