`6 Claims. (£2. 222-129)
`
`This invention relates to multicompartment dispensing
`packages and particularly to a novel assembly and meth
`od wherein an inner container is mounted in a special man
`ner within an outer container, the containers providing
`isolated ?uid compartments for simultaneous dispensing.
`The invention in its preferred embodiment concerns
`a relatively standard outer container, ?llable by conven
`tional can ?lling arrangements, and a special subassem
`bly of inner container and dispensing structure combined
`with the top or" the outer container which may be sepa
`rately ?lled, inserted into the outer container and attached
`thereto by a ‘more or less conventional can forming ar
`rangement.
`The major object or" this invention is to provide a novel
`manner of making a multicompartment dispensing pack—
`age wherein the inner container is incorporated in sub
`assembly with the top of the outer container and the two
`containers are separately ?lled before being attached in
`?nal assembly, the operation including the use of con
`ventional single container ?lling apparatus as much as
`possible, particularly in the steps of ?lling the outer con
`tainer and attaching the top structure thereto.
`It is a further object of this invention to provide a
`multicompartment dispensing package made by a novel
`method to produce a ?nished ?lled product of novel con
`struction.
`'
`
`Further objects of the invention will presently appear
`as the description proceeds in connection with the ap‘
`pended claims and the annexed ‘drawings wherein:
`‘FIGURE 1 is a section through a multicompartment
`dispensing package showing the special subassembly of
`the outer container top ‘and the inner container; and
`FIGURE 2 is a section on line 2—2 of FIGURE 1
`showing the fluid discharge openings and the inner con
`tainer spout connection to the neck.
`in the illustrated embodiment the multicompart
`rncnt dispensing package consists essentially of an outer
`container 11 and an inner container 12 combined in a
`special manner which enables optimum use of ‘standard
`single container ?lling and handling equipment.
`The outer container 11 comprises conventional can
`body structure of cylindrical, oval or rectangular cross
`section having a continuous annular side wall 13, a closed
`bottom 14 and an open top. Wall 13 and bottom 14 may
`be of integral conventional sheet metal or plastic struc
`ture formed in the usual manner as by stamping or mold
`ing. This open topped body may be ?lled to desired level
`with a suitable liquid by conventional ‘single container
`?lling apparatus.
`The open upper end of the outer container body is
`adapted to be closed by a sheet metal or plastic top mem
`ber 15 which is clenched or heat sealed as at 16 about
`its outer periphery around the upper edge of wall 33.
`Top 15 is annular with a central opening de?ned and
`surrounded by an upstanding neck 17 which is preferably
`cylindrical and formed externally with threads 13 for
`attachment of a cap 19.
`The inner container 12 is advantageously a semi-rigid
`polyethylene integral bottledike structure having a closed
`?at bottom 21 adapted to rest on the outer container
`bottom 14, an annular side wall 22 and a top opening
`merging into a relatively stiff spout tube 23 of smaller
`
`2
`diameter than neck 17. Spout tube 23 may be a rigid
`polyethylene part integral or heat bonded to the inner
`container 12 and it constitutes the only ?lling and dis
`charge opening for the inner container.
`It will be observed that the inner container is smaller
`in cross section than the outer container, whereby isolat
`ed inner and outer liquid or other fluent material corn
`partment spaces 24 and 25 are provided. On its outer
`surface inner container wall 22 may have rigid therewith
`a plurality of integral or otherwise ?xed projections 26
`adapted to extend through outer space 25 into supporting
`contact with the outer container wall.
`rejections 26
`may be of rubber or like resilient material to buffer
`‘shocks to the inner container.
`Spout tube 23 is rigidly secured to neck 17 as by the
`radial webs 27. These webs 27 may be of metal or plas
`tic suitably ?xed to both the neck and the spout tube
`with su?icient strength to support the weight of the inner
`container 12 and contents during ?lling if necessary.
`As shown in FIGURE 2 spout tube 23 and the neck 17
`provide for simultaneous discharge of the different liquids
`or powders from compartment spaces 24 and >25, in such
`relative proportions as may be determined by their rela—
`tive cross-sectional areas. Webs 27 offer little resistance
`to ?ow, and may even induce some turbulence to aid
`immediate mixing of the discharged materials.
`A special cap 19 closes both compartments at the same
`time, ‘and is turnably mounted on threads 18. Internally
`cap 19 has a downwardly projecting hollow cylindrical
`boss 28 surrounded by a ?at annular surface 29. When
`cap 19 is turned tight boss 28 telescopes snugly over spout
`23, and face 29 bridges the annular space between spout
`23 and neck 17, thus sealing oil both compartments at
`the same time.
`A very important aspect of the invention is the sub
`combination structure which is used in the novel ?lling
`sequence.
`1
`This involves the incorporation of the outer container
`top assembly with the inner container in such a manner
`that after the inner container has been ?lled the pack
`age assembly may be completed by the single operation
`of attaching the top member 15 over the open ?lled outer
`container merely by effecting the seal at 16.
`In practice we assemble the inner container with its
`spout 23 rigidly attached within neck 17 which is rigid
`or integral with the outer. container top 15. The inner
`container in this 'subassernbly can be filled in special
`machinery in a special ?lling’ line, and then the sub
`assembly including the ?lled inner container transported
`suitably :into the conventional single container ?lling line
`where it is assembled with the outer container by inser—
`tion from above until top 15 rests on the upper edge of
`wall 13. Now the assembly proceeds to the next position
`Where the crimping and sealing operation is e?ected at
`16 just as for a single compartment container.
`The invention is of such scope as to include the mount
`ing of inner containers that are so ?em'ble as to be plastic
`and distended by their contents. In any event the pro
`jections 26 locate and hold the ?lled inner container
`against shifting in the complete package.
`The inner and outer containers may have any desired
`shape, usually comprising a ?gure of revolution about an
`axis centrally of spout tube 23. The spout 23 must be
`of su?icient length to maintain the tops of the containers
`su?iciently spaced so as not to interfere with ?ow of
`liquid from the outer space 25, and the open top of wall
`13 must of course be large enough to accommodate in
`sertion of the ?lled inner container.
`The invention may be embodied in other speci?c forms
`without departing from the spirit or essential charac
`teristics therefor. The present embodiments are there
