Abstract: Strands of multicolored, striped toothpaste, more especially with a cross-section in the form an n-sided polygon, where n is an integer of 3 to 7, can be dispensed without diffuse transition zones from a storage container providing the ratio between the yield points of the carrier strand paste and the stripe paste is approximately 1.10:1 to 1.20:1. A device of the type shown in FIG. 1 is suitable for dispensing the toothpaste.

Abstract: A dispensing device for dispensing at least two flowable substances includes a container with two separate coaxial compartments for containing two flowable substances, respectively. Independently operable dosing units are associated with each compartment. Each dosing unit communicates with its associated compartment through a valve flap. Each dosing unit also includes a spring-actuated plunger guided in a cylinder, with a valving mechanism for enabling a predetermined quantity of the associated flowable substance to be selectively dispensed.

Abstract: A device for dispensing a striped mixture of two components of a paste-like flowable substance includes a lower container in which one of the components is retained. A dosing unit mounted on the container, includes a pushbutton which is depressed for forcing the first component from the container through a set of valves into a compartment of the dosing unit, through a centrally located tubular element within the compartment, and out of an upper outlet for dispensement from the device. The interior of the compartment between the tubular element is filled with a second component, which is forced upward by the first component entering the compartment, and into the tubular element via openings therethrough, for mixing with the first component as it moves through the tubular element and out of the outlet, for dispensing a striped mixture of the first and second components.

Abstract: Combinable bottle assembly (1,6) consisting of two separately fillable bottles designed to be fitted together one above the other, can be formed inexpensively of plastic, filled and stored separately from and independently of one another and can readily be connected and tightly combined with one another to form a two-compartment container convertible to a one compartment container.The floor or bottom wall (12) of the upper bottle (1) is formed as a separate cylinder element (3) having an annular connecting plate (13) which connects a skirt wall (14) of the cylinder element to the wall (15) of a central nozzle (9) arranged concentrically therein, forming a throughflow passage (16) which is closed by a stopper (10). The lower bottle (6) comprises an elongate neck having an external screwthread (33) which is engagable with an internal thread on the elongate nozzle to permit the second bottle to be screwed into the nozzle to a connecting position to dislodge the stopper and open the containers to each other.
