Description
CROSS REFERENCES TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional
Application No. 60/487,366, filed Jul. 15, 2003, the disclosure of
which is incorporated by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to containers and refill
packages for compositions. More specifically, the present invention
relates to containers and refill packages for liquid and granular
compositions.
BACKGROUND OF THE INVENTION
[0003] Containers for holding and dispensing granular and/or liquid
compositions, such as laundry detergents fabric softeners, etc.,
are well known in the art. Containers for granular compositions are
often paperboard boxes, but can also be bottle-type containers such
as are typically used for liquid compositions. These bottle-type
containers typically contain a hollow bottle, a pouring spout, and
a cap to prevent spillage. These containers, or parts thereof are
usually formed from plastics, polymers, resins, paper, and/or
laminates. While such containers are typically disposable and/or
recyclable, some consumers and companies prefer that these
containers be refillable, so as to reduce product cost, generation
of garbage waste, etc. Accordingly, light weight disposable and/or
recyclable refilling containers such as refill pouches have been
developed. Once the container is empty, the composition in the
refill pouch are then typically poured into the container to refill
it. Typically, the cap and/or the pouring spout are removed to
facilitate such refilling.
[0004] This refilling experience has now been found to cause
frustration with many consumers, as the process is time consuming,
especially for viscous compositions which do not pour very quickly.
In addition, the refilling process can be messy as the composition
drips or overflows part of the pouring spout and/or container.
Finally, due to the above difficulties, refilling can be
inconvenient as the process requires continuous concentration and
attention, as the user tries to minimize messiness and keep the
product flowing into the container.
[0005] Accordingly, the need exists for a refilling system which is
less messy, which is easier and more convenient to use, relatively
stress-free, which refills quickly, and/or which refills faster.
The need also exists for a refilling system for liquid compositions
which meets the above objectives, in a cost-effective manner.
SUMMARY OF THE INVENTION
[0006] The present invention relates to a refilling system for
reducing messiness during use includes a container and a refilling
container. The container includes a hollow bottle, a pouring spout,
and a cap which covers the pouring spout. The pouring spout has an
interior surface. The refilling container includes a hollow body a
refilling spout and contains a composition therein. The refilling
spout has an exterior surface. In the refilling system, the
interior surface and the exterior surface are coordinated such that
the exterior surface may fit within the interior surface during
use.
[0007] It has now been found that by carefully coordinating the
size and/or shape of the exterior surface of the refilling spout
with the interior surface of the pouring spout, the overall
refilling experience can be significantly enhanced. Moreover,
messiness and dripping can be minimized or even eliminated, while
speed of refilling can be significantly enhanced. As less time is
spent in the refilling process, the overall consumer experience is
made more satisfying and less stressful. Also significantly less
consumer concentration is required when using the refilling system
herein.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] While the specification concludes with claims particularly
pointing out and distinctly claiming the invention, it is believed
that the invention will be better understood from the following
description of the accompanying figures in which like reference
numerals identify like elements, and wherein:
[0009] FIG. 1 shows a partial side view of an embodiment of the
refilling system of the present invention, during use; and
[0010] FIG. 2 is a side view of an embodiment of the refilling
container of the present invention.
[0011] The figures herein are not necessarily drawn to scale.
DETAILED DESCRIPTION OF THE INVENTION
[0012] All temperatures are in degrees Celsius (.degree. C.) unless
otherwise specified.
[0013] As used herein, the term "comprising" means that other
steps, ingredients, elements, etc. which do not affect the end
result can be added. This term encompasses the terms "consisting
of" and "consisting essentially of".
[0014] As used herein, the term "during use" means during refilling
of the hollow bottle with the refilling container.
[0015] FIG. 1 shows a partial side view of an embodiment of the
refilling system, 10, of the present invention, during use. The
refilling system, 10, includes a container, 12, which is formed of
a hollow bottle, 14. The hollow bottle, 14, has a pouring spout,
16, and a cap, 18. The pouring spout, 16, may be either integral
with the hollow bottle, 14, or may be connected thereto by
mechanical, electrical and/or chemical means. The composition,
preferably a granular or liquid composition, and more preferably a
liquid composition, may be poured from the pouring spout, 16, when
the cap, 18, is removed. Such a container, and/or portion thereof
is typically formed of plastic, glass, paper and/or metal,
preferably a polymer or resin such as polyethylene, polypropylene,
polyethylene terephthalate, polycarbonate, polystyrene, ethyl vinyl
alcohol, polyvinyl alcohol, thermoplastic elastomer, and
combinations thereof, although other materials known in the art may
also be used. Such containers typically hold from about 100 mL to
about 6 L, preferably from about 150 mL to about 4 L, more
preferably from about 200 mL to about 2 L, and even more preferably
from about 500 mL to about 1.5 L of liquid or granular composition,
and are well known for holding such products. Such containers are
widely available from many packaging suppliers.
[0016] Preferred examples of the container, and/or portions thereof
useful herein include GB Design Patent Application No. 3010528 and
3010529, both to Isono, filed on Jan. 30, 2003. Textured surfaces
may also be employed so as to enhance gripping, if desired.
Preferred production processes include blow molding, injection
molding, injection blow molding, vacuum forming, thermoforming,
pulp molding and combinations thereof. For a pulp paper container,
preferred processes include those described in JP Patent No.
3072088 B1 to Kumamoto, and JP Patent No. 3072104 B1 to Tsura, both
published on Jul. 31, 2000.
[0017] The refilling system, 10, also includes a refilling
container, 20, which has a hollow body, 22, containing a refilling
spout, 24, and a composition, 26, inside of the hollow body, 22.
The refilling spout, 24, has an exterior surface, 28, which is
coordinated with an interior surface, 30, of the pouring spout, 16.
The exterior surface, 28, is coordinated with the interior surface,
30, in a manner such that the exterior surface, 28, fits into the
interior surface, 30, preferably, the exterior surface, 28,
removably attaches to the interior surface, 30, for example by
securing, locking and/or fitting together so as to reduce spillage
and messiness. Therefore, it is highly preferred that either at
least a portion of the interior surface, 30, be formed of a
flexible, collapsible, and/or bendable material, and/or that at
least a portion of the interior surface, 30, have a greater
circumference than at least a portion of the exterior surface, 28,
so that the exterior surface, 28, may be fitted into the interior
surface, 30. A preferred refilling container is formed of a
material which includes a film, a laminate, a plastic, a polymer, a
resin, a metal, and/or paper, more preferably polyethylene,
polyethylene terephthalate, polypropylene, nylon, aluminum and a
combination thereof. Such refilling containers may also be
coextruded, or formed via other methods known in the art, such as
described above.
[0018] In FIG. 1, the cap, 18, is preferably transparent and/or
translucent, and contains at least one measuring indicator, 32.
Such a preferred measuring indicator may be, for example,
integrally molded into the cap, and or may be added later, such as
via a printing process. The measuring indicator, 32, may be on any
surface of the cap, and is preferably in the inside. The cap is
preferably removable, but may also be affixed to the hollow bottle,
14, as desired by a hinge, a flexible strip of plastic, a string,
and/or other appropriate attachment mechanism.
[0019] The refilling container, 20, is typically selected from a
pouch, a bag, a pocket, and/or a box, bottle, preferably a pouch.
The refilling container, 20, is usually formed of a bendable
material, and in FIG. 1, it can be seen that the refilling
container, 20, may be flattened, rolled and/or folded during the
refilling process, so as to reduce wasted composition, spillage,
and/or messiness. Simultaneously flattening, rolling and/or folding
the refilling container during the refilling process also tends to
squeeze the composition out of the container, thereby may also
significantly reducing the time needed to drain substantially all
of the composition out of the refilling container. Once rolled
and/or folded, the refilling container may be held is such a
compacted state via a securing mechanism such as a piece of tape,
34. Preferred securing mechanisms useful herein include a piece of
tape, a snap, a button, a hook-and-loop system (e.g., VELCRO.TM.),
and/or an adhesive, more preferably a tape. It is especially
preferred that such a securing system be easy and cost-effective to
apply and/or form with the refilling container, 20, and also be
prevented from unintentionally securing to other containers, and/or
surfaces during filling, manufacture, shipping, etc. The, preferred
tape herein is typically self-adhesive, folded over itself, and is
well-known for securing and holding closed used diapers, and may be
provided on the refilling container, 20, or may be provided
separately. Such a preferred tape is described in detail in, for
example, JP Patent No. 3222871 B2, to Hayase, et al., published on
Oct. 29, 2001.
[0020] In FIG. 2, is shown of an embodiment of the refilling
container, 20, of the present invention, which is a pouch formed of
a transparent film which is sealed after the composition, 26, is
added. The seal, 36, may be formed by methods well-known in the
art, such as via heat-sealing, ultrasonic sealing, pressure
sealing, employing adhesives, etc. The refilling container, 20,
contains a composition, 26, and an optional pouch hole, 38. The
pouch hole, 38, allows easy carrying, holding, pouring, and storage
(e.g., via hanging) of the refilling container, 20. Furthermore,
the refilling spout, 24, contains a tube, 40, therein which is a
hollow passageway which allows easy pouring and draining of the
composition, 26, during use. The tube, 40, may also be affixed to
the pouring spout, 24, in any manner known in the art, as described
above, or may be formed with the refilling container itself. The
tube, 40, is typically formed from plastic, rubber, metal, or a
mixture thereof.
[0021] In FIG. 2, both the refilling spout, 24, and the tube, 40,
are cut by a highly preferred hand-tear line, 42, which separates
the tear-off portion, 44 with the refill spout, 42 and the tube,
40. The hand-tear line, 42, is preferably formed by at least one,
preferably multiple, and more preferably from about 2 to 15 score
lines cut or formed by a laser, or other implement. The cut from
the hand-tear line, 42, and the edge of the refilling spout, 24,
form an acute angle, .alpha., which makes it easier to insert the
refilling spout, 24, into the pouring spout, (see FIG. 1 at 16),
and is especially useful to reduce dripping and spillage during the
initial refilling stage when the refilling spout, 24, is first
inserted into the pouring spout (see FIG. 1, at 16). Without
intending to be limited by theory, it is believed that having a
solid plastic piece such as the tube, 40, in the spout, 24, makes
the otherwise bendable spout, 24, more stable during use, so that
the exterior surface, 28, can more easily be put into the interior
surface, 30. In the preferred embodiment of FIG. 2, the edges of
the tube, 40 and the refilling spout, 24, are not parallel.
However, if the edges of the tube and the refilling spout are
parallel, then a similar acute angle is formed by the hand-tear
line and the edge of the tube, 24. While it is preferred that the
tube also be cut at an acute angle, such a feature may increase
manufacturing cost, and therefore other cuts such as right
angle-cut tubes are also envisioned herein.
[0022] As suggested by the name, the hand-tear line, 42, may be
easily torn from the refilling container so as to open the
refilling container for use. However, alternative methods for
opening the refilling container are also useful herein, such as
having a reclosable seal and/or cap on the refilling spout, having
an indication that the refilling spout should be cut with a knife
and/or scissors, etc.
[0023] If during use the refilling container is to be flattened,
rolled, folded, etc., this process should begin at the bottom end,
46, which is distal from the refilling spout, 24, and proceed
towards the refilling spout, 24.
[0024] In a preferred embodiment, the refilling system allows
hands-free, stable refilling of the hollow bottle as the refilling
container drains. Such a preferred refilling system may be provided
by designing the refilling container, the container, and/or parts
thereof such as the pouring spout and the refilling spout such that
they stably and removably lock, screw, and/or snap together.
Alternatively, the refilling container, container, and/or parts
thereof may be designed such that during use, the refilling
container stably rests upon the pouring spout in a balanced manner.
By designing the refilling container to stably rest upon the
pouring spout, and to remain balanced thereupon as the composition
therein drains, the consumer refilling experience is remarkably
improved. This preferred embodiment allows such hands-free, stable
refilling without requiring that the consumer actually hold the
refilling container during the entire draining process. As it may
take 5 minutes or more for a truly viscous composition in the
refilling container to completely drain into the container, such
freeing up of the consumer's hands and concentration is especially
desirable. Such a preferred embodiment may also allow a consumer to
simply start the refilling process by opening the refilling
container and the container, affixing the refilling spout of the
refilling container to the pouring spout of the container, placing
the refilling system on a stable, flat surface, and then leaving
the refilling system until draining is complete. This will ensure
almost total emptying of the composition from the refilling
container into the container's hollow bottle. This in turn reduces
that amount of composition wasted due to the impatience of certain
consumers during the refilling process.
[0025] In a preferred embodiment, the tube and or the refilling
spout is flexible and/or extendable so as to more easily allow for
refilling of the hollow bottle. Such an embodiment may also make
the refilling container more stable during use.
[0026] All documents cited in the Detailed Description of the
Invention are, are, in relevant part, incorporated herein by
reference; the citation of any document is not to be construed as
an admission that it is prior art with respect to the present
invention.
[0027] While particular embodiments of the present invention have
been illustrated and described, it would be obvious to those
skilled in the art that various other changes and modifications can
be made without departing from the spirit and scope of the
invention. It is therefore intended to cover in the appended claims
all such changes and modifications that are within the scope of
this invention.
EXAMPLE 1
[0028] A refilling system as in FIG. 1 is provided, employing the
refilling container of FIG. 2. The container is formed from blow
molded polypropylene, and the refilling container is formed of a
155.mu. thick laminated film containing nylon (25.mu.)/linear low
density polyethylene (130.mu.). A semi-rigid polyethylene tube is
present in the refilling spout. The refilling container contains a
clear fabric softening composition.
[0029] The refilling spout has an exterior surface which is
generally an oval having a minimum diameter of about 9 mm and a
maximum diameter of about 12 mm. The interior surface of the
pouring spout is also generally an oval having a minimum diameter
of about 12 mm, and a maximum diameter of about 18 mm. Thus, the
refilling spout and even the seal edges of the refilling spout fit
easily into the pouring spout during use of the refilling system to
pour the composition into the container, and the hollow bottle.
[0030] An instruction set is provided on the back of the refilling
bottle which provides written and graphical step-by-step
instructions to tear off the tear-off portion in order to open the
refilling container, to insert the refilling spout into the pouring
spout of a relatively empty container, to invert the refilling
container while keeping the refilling spout inserted in the pouring
spout, to begin flattening, squeezing, rolling and/or folding
refilling container from the bottom end towards the pouring spout,
and then to tape the flattened/squeezed/rolled/folded container
closed when the refilling process is complete. When used as
instructed, the refilling system provides quick and easy refilling
of the container while also minimizing dripping and waste.
[0031] All documents cited in the Detailed Description of the
Invention are, are, in relevant part, incorporated herein by
reference; the citation of any document is not to be construed as
an admission that it is prior art with respect to the present
invention.
[0032] While particular embodiments of the present invention have
been illustrated and described, it would be obvious to those
skilled in the art that various other changes and modifications can
be made without departing from the spirit and scope of the
invention. It is therefore intended to cover in the appended claims
all such changes and modifications that are within the scope of
this invention.
