Abstract
Description
- This invention relates to multiple cavity pump dispensing packages.
- 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.
- EP 0 747 299 discloses a multi-chamber refillable dispenser where the piston element is separate from the main body of the dispenser. The single chamber dispenser in EP 0 605 890 also discloses a piston that is separate from the plunger element of the dispenser. US 5 289 949 also discloses a multi-chamber dispenser where the piston element is separate and unwanted mixing of the contents of the two chambers, at the nozzle, is prevented by an extended septum.
- 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, there is provided a multiple cavity dispensing package as defined in claim 1. The package comprises a first hollow plastic body and a second hollow plastic body that interengage to define dual pump. The first plastic body is molded in one piece and includes an integral lateral nozzle with a cap integrally hinged thereto. The second plastic body includes integral pistons. The first plastic body includes integral cylinders, integral tubes extending through the integral nozzle. The cap includes dual plug seals which seal against the internal peripheral surfaces of the dual outlets of the nozzle.
- The present invention also provides a method of making a multiple cavity dispensing package as defined in claim 4. It must be noted that the embodiment of Figures 1-10 wherein the pistons are separate is not part of the invention.
-
- Fig. 1 is a perspective view of a multiple cavity dispensing package embodying the invention.
- Fig. 2 is an exploded perspective view, showing the cap in open position.
- Fig. 3 is a top plan view.
- Fig. 4 is a part sectional view taken along the line 4-4 in Fig. 3.
- Fig. 5 is a sectional view taken along the line 5-5 in Fig. 4.
- Fig. 6 is a sectional view taken along the line 6-6 in Fig. 3.
- Fig. 7 is a fragmentary sectional view at the
circle 7 in Fig. 4. - Fig. 8 is a top plan view of the lower plastic body in Figs. 1 and 2.
- Fig. 9 is a fragmentary front elevational view on an enlarged scale with the cap in open position.
- Fig. 10 is a sectional view taken along the line 10-10 in Fig. 9.
- Fig. 11 is a part sectional elevational view similar to Fig. 4 showing a modified form of a multiple cavity dispensing packages.
- Fig. 12 is an elevational view of a portion of the package shown in Fig. 11.
- Fig. 13 is a sectional view taken along the line 13-13 in Fig. 12.
- Fig. 14 is a sectional elevational of the second lower part of the package shown in Figs. 12 and 13.
-
- Referring to Figs. 1-10, the multiple
cavity dispensing package 10 comprises a first upper hollowplastic body 12 and a second lower hollowplastic body 14 that interengage to define a dual pump. The firstplastic body 12 is molded in one piece and includes an integrallateral nozzle 16 having dual outlets with acap 18 integrally hinged byhinge 20 tobody 12. The secondplastic body 14 includespistons 22. The firstplastic body 12 includesintegral cylinders 24 that define product chambers andintegral outlets 26 extending through theintegral nozzle 16. As in the aforementioned patents 5,020,694, 5,289,949 and 5,332,124, when product is placed in the cylinders and thefirst 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 inintegral 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 thelower 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 body cap body passages nozzle - 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.
