Estimating the term…
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.
A plastic blow molded container, said container having sidewalls, a base at one end of said sidewalls with a dispensing means at an other end of said sidewalls to define the body of said container, a dispensing means exit for the removal of substances from said dispensing means, a plurality of separate chambers within said container, each chamber being separate from the base through the dispensing means, continuous webs within said container and extending from said-base to said dispensing means exit separating said container into said plurality of separate chambers, said continuous webs formed along with said container during the blow molding of said container and being of a lesser thickness at about a midpoint region thereof so that said webs flex when said sidewalls of said container are compressed to deliver product from said container body to said dispensing means.
A plastic blow molded container, said container having sidewalls, a base at one end of said sidewalls with a dispensing means at an other end of said sidewalls to define the body of said container, a plurality of continuous webs extending from said base to said dispensing means, said webs dividing the body of said container into a plurality of separate chambers, said webs being of a lesser thickness at about a mid-point thereof so that said webs flex when said sidewalls of said container are compressed to deliver product from said container, and an outwardly extending flange at the junction of said sidewalls and said dispensing means, said flange having at least one upwardly extending lug to hold a closure in place.
