MULTIPLE CAVITY DISPENSING PACKAGE

EMBALLAGE DE DISTRIBUTION A CAVITES MULTIPLES

English Abstract

A multiple cavity dispensing package including a first upper hollow plastic
body having an open lower end and a second lower hollow plastic body 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 having dual outlets. An integral cap is hinged to the spout
and closes the outlet. Integral product chambers 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.

French Abstract

L'invention porte sur un emballage à plusieurs cavités de distribution. L'emballage comporte un premier corps de plastique creux supérieur ayant une extrémité inférieure ouverte et un second corps de plastique creux inférieur ayant une extrémité supérieure ouverte. Des pièces, agissant les unes par rapport aux autres, du premier et du second corps de plastique définissent une série de pompes. Le premier corps de plastique creux constitue un corps de plastique moulé en une pièce et comporte un bec intégral à deux sorties. Un bouchon intégral est articulé au bec de façon à fermer les sorties. Des chambres de produits intégrales et des passages intégraux, dans le premier corps de plastique, se prolongent jusqu'aux sorties du bec. L'emballage de distribution fonctionne par le déplacement relatif du premier corps de plastique vers le second corps de plastique; il est ainsi possible de distribuer le contenu des chambres au moyen du bec.

MULTIP~E CAVITY DI8PEN8ING P~
This invention relates to multiple cavity pump
dispensing packages.
Background and 8ummary of th- 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

CA 0223~8~6 1998-04-23
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 th- Pr-ferr-d 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.

CA 0223~8~6 1998-04-23
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.
