Abstract

A multiple cavity dispensing package including a first upper hollow plastic body (12 or 12a) having an open lower end and a second lower hollow plastic body (14 or 14a) having an open upper end. Interengaging parts in the first plastic body and the second plastic body defining plural pumps. The first hollow plastic body is a one-piece molded plastic body and includes an integral spout (16 or 16a) having dual outlets (26 or 26a). An integral cap (18) is hinged to the spout and closes the outlet. Integral product chambers (24 or 24a) and integral passages in the first plastic body extend from the chambers to the outlets of the spout. The dispensing package is operable upon relative movement of the first plastic body toward the second plastic body to dispense the contents of the chambers through the spout.

Description

This invention relates to multiple cavity pump dispensing packages.
Background and Summary of the Invention
Multiple cavity dispensing packages of the pump type are shown in U.S. Patents Nos. 5,020,694, 5,289,949 and 5,332,124.
In U.S. Patent No. 5,289,949, there is disclosed a package comprising an upper housing on which a nozzle is snapped into position and a closure snapped onto the nozzle. The upper housing is slidably received in a lower housing which supports dual pistons such that when the upper housing is depressed dual streams of two materials are dispensed. Such a package is shown in the prior art. Such a package comprises a dispensing pump including an upper shroud with two integral cylinders, which slidably accommodate pistons fixed on a lower shroud. The cylinders contain the product which is to be dispensed. The upper shroud includes dual outlets extending laterally of the upper shroud with two passages connected to the two cylinders. A dual outlet assembly snaps into the upper shroud and has dual passages communicating with the dual outlets and extending laterally of the upper shroud. A nozzle snaps on the dual outlet assembly and engages the dual outlets. A cap is hinged to the nozzle. The cap is provided with a septum for maintaining the two products to be dispensed separate and are not intermixed when the cap is closed.
Among the objectives of the present, invention are to provide a multiple cavity dispensing package which is less complex, which uses a minimum number of parts, which is less costly to manufacture by using fewer molds, and which is easier to assemble.
In accordance with the invention, the multiple cavity dispensing package comprises a first hollow plastic body and a second hollow plastic body that interengage to define dual pump. The second plastic body is molded in one piece and includes an integral lateral nozzle with a cap integrally hinged thereto. The first plastic body includes integral pistons. The second plastic body includes integral cylinders, integral tubes extending through the integral nozzle. The cap includes dual sealing plugs which seals against the internal peripheral surfaces of the dual outlets of the nozzle.

Detailed Description of the Preferred Embodiment
Referring to Figs. 1-10, the multiple cavity dispensing package 10 comprises a first upper hollow plastic body 12 and a second lower hollow plastic body 14 that interengage to define a dual pump. The first plastic body 12 is molded in one piece and includes an integral lateral nozzle 16 having dual outlets with a cap 18 integrally hinged by hinge 20 to body 12. The second plastic body 14 includes pistons 22. The first plastic body 12 includes integral cylinders 24 that define product chambers and integral outlets 26 extending through the integral nozzle 16. As in the aforementioned patents 5,020,694, 5,289,949 and 5,332,124, incorporated by reference, when product is placed in the cylinders and the first part 12 is depressed, the product is dispensed.
Further, in accordance with the invention, the cap includes integral plug seals which engage the complementary inner surfaces of the outlets 26 in integral nozzle 16.
In a modified form shown in Figs. 11-14, the seals are made integral with the pistons 22a which are, in turn, fixed on the lower body 14a. Corresponding parts are designated with a suffix "a".
In each of the forms, the product to be dispensed is introduced into the cylinders 24, 24a and the body 12 and 14 are assembled. In order to dispense the products, the cap 18, 18a is opened and the body 12, 12a is depressed to dispense the two products through the passages 26, 26a in nozzle 16, 16a.
It can thus be seen that there has been provided a multiple cavity dispensing package which is less complex, which uses a minimum number of parts, which is less costly to manufacture by using fewer molds and which is easier to assemble.
