Description
The present invention relates to mixing and dispensing containers
which have two or more containers held together in use, but which
comprise separate containers, each of which contains a product
which is not desired to be exposed to the other product until
shortly before it is desired to use the product which results from
mixing the contents of the two containers.
In accordance with a first embodiment, one of the containers can be
a standard container of glass or other similar material having
therein a first product, the same being sealed by a removable end
cap. The other of the two containers is a hermetically sealed
plastic container and advantageously can be of the type which is
formed, filled and sealed in one continuous operation. This second
container is filled with a second product, and has a threaded neck
portion on its one end. A coupler is provided and is adapted to be
affixed to both containers to affix them together and to provide an
opening into the second container to thereby permit the two
products to be mixed together.
When it is desired to mix the contents of the two containers, the
cap is removed from the container containing the first product and
the coupler is affixed thereto. Next, the neck portion on the
plastic container is threaded into the coupler, and in doing so, a
portion of the neck portion is severed, thereby opening the plastic
container and permitting the product therein to flow into and
become mixed with the product in the other container. After mixing
the contents, the resulting product can be dispensed by severing
the tip of the spout provided on the plastic container.
In accordance with a second embodiment, both containers are of a
hermetically sealed plastic type, and the coupler is formed to both
affix the two containers together and to sever both the seals
closing the neck portions thereof, to permit the contents to be
mixed.
It is very common today in the cosmetic field, and in particularly
in the field of women's hair care, to apply various bleaching or
dyeing preparations to the hair. These preparations are in great
demand because of their relative safety and reliability, and
because asthetically pleasing results can be obtained with them at
a fairly low cost.
However, although these preparations are reliable in use, they are
made from ingredients which react with each other and are
relatively unstable from a chemical standpoint. Typical ingredients
of these bleaches or colorants or other preparations are various
peroxides, permanganates and other strong oxidizers, as well as
other acids and bases which attack materials from which many
containers are commonly made.
When these products are mixed with each other a certain amount of
neutralization takes place whereby the product is physically safe
and relatively harmless. However, storage of the components has
presented considerable problems, and in the case of certain
preparations which are widely accepted, it is absolutely necessary
to keep the two components separated from each other until just
before the time of use. Thus, although convenient in many ways
compared to older styles of hair treatment operations, very serious
drawbacks to safe and efficient operation, and to convenience for
home applications are presented in today's packages by reason of
the fact that the user or operator must mix these chemically strong
ingredients by pouring or squeezing the contents of one container
into another, and then sealing the container and agitating it
before dispensing the mixed contents therefrom.
In view of the shortcomings of the prior art, and in view of the
large number of such preparations which are sold today, there is a
great demand for an improved package for hair coloring or bleaching
preparations, or the like, in which two components, which are
desired to be mixed later, but which must first be kept separate
from each other, may be contained, and in which the container may
be safely shipped and attractively merchandised. There is also a
demand for such an arrangement which is capable of being simply
manipulated to establish a communicating passage between two
separate, product-containing containers.
Accordingly, it is an object of the present invention to provide a
pair of containers each of which includes a separate product to be
mixed together before use, and a coupler for affixing the two
containers together, in a fashion such as to permit the two
products to be mixed with one another.
Another object is to provide an arrangement as described above
wherein one of the containers can be of a standard type of glass or
other similar material and the other container can be of plastic,
thereby permitting a selection of appropriate containers which are
resistant to attack by the product to be contained therein.
Still another object is to provide such an arrangement wherein one
of the containers is adapted to be easily opened after the two
products have been mixed, to permit the mixed product to be
dispensed.
A still further object is to provide such an arrangement wherein
the two containers can be easily and quickly affixed together to
mix the products therein, and to open at least one of the
containers to permit the mixed product to be dispensed.
Other objects of the invention will in part be obvious and will in
part appear hereinafter.
The invention accordingly comprises an article of manufacture
possessing the features, properties, and the relation of elements
which will be exemplified in the article hereinafter described, and
the scope of the invention will be indicated in the claims.
For a fuller understanding of the nature and objects of the
invention, reference should be had to the following detailed

FIG. 9 is a perspective view of the assembled combination.
Similar reference characters refer to similar parts throughout the
several views of the drawings.
Referring now to the drawings, in FIG. 3 there is shown a container
10 having a neck portion 11 with threads 12 thereon. This container
10 can be of plastic or other suitable material such as glass,
which will resist attack by the product container therein. The
container 10 is adapted to be closed by a threaded cap 14, or in
the manner described more fully below.
In FIG. 1, a second container 16 is shown, and this container 16 is
of plastic and is advantageously of the type which is formed,
filled and hermetically sealed all in one continuous operation,
generally in the fashion disclosed in U.S. Pat. No. 3,597,793, to
Automatic Liquid Packaging, Inc. The container 16 has a body
portion 19 which is closed at its one end by a neck portion 20
having threads 21 thereon. Between the neck portion 20 and the body
portion 19 of the container, there is provided an annular
bead-shaped rim 18, the purpose of which is described more fully
below. A spout 22 is provided on the opposite end of the body
portion 19 of the container 16, and the spout is closed by means of
a twist off closure 23. A weakened annular groove 24, couples the
spout 22 and the closure 23, to permit the latter to be more easily
severed from the container 16. This container 16 contains a second
product which is ultimately intended to be mixed with the product
in the container 10.
In FIG. 2 there is shown a coupler 28 which is provided for
affixing the two containers 10 and 16 together, and to permit the
contents thereof to be mixed with one another. This coupler 28 has
a cylindrical-shaped side wall 29 and an inner cap portion 30 which
is supported therein by means of a connecting flange 31. The inner
cap portion 30 is of a hollow cylindrical construction, and has
threaded cavities 32 and 33 therein which are adapted to threadedly
receive therein the neck portion 11 of the container 10 and the
neck portion 20 of the container 16 respectively. An annular shaped
cutting edge 34 extends upwardly into the threaded cavity 33, and
is spaced from the interior walls thereof so as to provide a
sealing cavity 35. The cylindrical side wall 29 also has an annular
groove 36 formed on its interior, which groove 36 is adapted to
snap-actingly receive therein the annular rim 18 on the container
16, to affix the coupler 28 to the container 16 when the neck
portion 20 thereof is threaded into the threaded cavity 33.
In affixing the containers 10 and 16 together to mix the products
contained in the two containers, the cap 14 first is threadedly
removed from the container 10. The coupler 28 then is threadly
affixed to the container 10, by threading the neck portion 11
thereof into the threaded cavity 32. The coupler 28 is threaded
down onto the container, until the edge of the cylindrical side
wall 29 abuts against the top edge of the container, in the manner
illustrated in FIG. 4.
Next, the neck portion 20 of the container 16 is threaded into the
threaded cavity 33 of the coupler 28, until the annular rim 18
snap-actingly engages within the annular groove 36 in the
cylindrical side wall 29 of the coupler. In threading the neck
portion into the coupler 28, the cutting edge 34 severs the sealed
end portion on the neck portion 20 (FIG. 4), thereby permitting the
product within the container 16 to flow through the threaded
cavities 32 and 33 into the container 10.
After mixing the two products by agitating the containers 10 and
16, the mixed product can be dispensed by twisting or bending or
otherwise removing the closure 23, at the annular groove 24, on the
spout 22. When the containers 10 and 16 are inverted, the mixed
product will flow from the container 10 through the threaded
cavities 32 and 33 into the container 16, and out through the spout
22.
In FIG. 8 there is shown another arrangement which can be used when
both products are packaged within hermetically sealed plastic
containers. The upper container (as illustrated) can be like the
container 16 and for purposes of illustration, is in this case,
shown to be the same. The lower container 46, in this case, is
formed of plastic and has a neck portion 47 having threads 48
thereon. As in the case of the container 16, an annular rim 49 is
formed thereon between the body portion 50 and the neck portion 47
of the container.
The coupler 58, in this embodiment of the invention, has a
cylindrical side wall 59 and interiorly thereof there is provided
an inner cap portion 60 which is supported therein by means of a
flange 61. The inner cap portion 60 is of a hollow cylindrical
construction and has threaded cavities 62 and 63 therein, formed to
threadedly receive the neck portion 47 of the container 46 and the
neck portion 20 of the container 16, respectively. Cutting edges 64
and 65 are formed in the threaded cavities 62 and 63, respectively,
and are spaced from the side walls of the inner cap portion 60 so
as to provide sealing cavities 66 and 67 therein. Annular grooves
68 and 69 are formed in the interior surface of the cylindrical
side wall 59, for receiving the annular rim 49 and 18 on the
containers 46 and 16, respectively.
In affixing the container 16 and 46 together to permit the products
therein to be mixed, the coupler 58 is affixed to the container 46
by threadedly engaging its neck portion 47 into the threaded cavity
62. The coupler 58 is threaded down onto the container 46, until
the annular rim 49 snap-actingly engages within the annular groove
68. As the coupler 58 is threaded onto the container 46, the
cutting edge 64 severs or cuts an opening into the sealed neck
portion 47, thereby opening the container 46. The annular rim 49
being disposed within the annular groove 68 in the coupler 58
provides a seal and also prevents the coupler 58 from being
inadvertently unscrewed from the container.
The neck portion 20 of the container 16 next is threaded into the
threaded cavity 63 of the coupler 58, to affix the container 16 to
the container 46. In this case also, the container 16 is threaded
into the coupler 58, until the annular rim 18 snap-fittingly
engages within the annular groove 69 in the cylindrical side wall
59 of the coupler 58. The cutting edge 65 severs or cuts an opening
into the neck portion 20 of the container 16, thereby opening the
latter and permitting the product therein to flow through the
threaded cavity 62 and 63 into the container 46.
After the products have been mixed by agitating or otherwise mixing
them, the mixed product can be dispensed therefrom by severing the
closure 23 from the container 16, in the manner described above.
The containers 16 and 46 and the coupler 58, when affixed together
form a unitary container generally as illustrated in FIG. 9.
It is apparent from the above description that various differently
shaped containers can be used, it only being essential that the
containers have a neck portion which can be affixed within the
coupler 28 or 58 in the described fashion. Also, while the couplers
28 and 58 are illustrated to have threaded neck cavities therein,
the neck cavities and the neck portions on the containers can as
well be correspondingly formed to be affixed together in other
different manners, for example, by means of snap-fitting
interlocking means and the like. With the arrangement illustrated
in FIGS. 1-4, the lower container 16 can be of various different
materials, for example, glass, depending upon the particular
product contained therein. If the product is not one which will
attack or is effected by association with a plastic material, the
container 16 can be of plastic also, in which case, the
construction can as well be like that of the container 46, and a
coupler like the coupler 58 used therewith. Various different
spouts or other dispensing means can be provided on the container
16.
Also, in the illustrated embodiment, it is contemplated that the
container 10 be sealed closed by means of the cap 14 being
threadedly affixed thereto. However, it will be appreciated that
the coupler 28 can be threadedly affixed to the container 10, and
the exterior of the upper end of the cap portion 30 can be threaded
to receive a cap such as the cap 14 to seal the container 10 and
the passage through the cap portion 30. In such a case, the cap is
merely removed from the cap portion 30, and the neck portion 20 of
the container 16 threaded into the neck cavity 33, in the manner
described above. Such an arrangement may be advantageously used in
shipping, storing and in merchandising the product.
The couplers 28 and 58 can be of any suitable material such as
metal or plastic, and if of plastic, can be easily and
inexpensively molded. It also can be attractively decorated and can
have instructions printed on its side wall, for assembling the two
containers.
It will thus be seen that the objects set forth above, among those
made apparent from the preceding description, are efficiently
attained and certain changes may be made in the above article.
Accordingly, it is intended that all matter contained in the above
description or shown in the accompanying drawings shall be
interpreted as illustrative and not in a limiting sense.
