Description
TECHNICAL FIELD OF THE INVENTION
[0001] This invention generally relates to plastic containers that
retain a commodity. More specifically, this invention relates to a
blow molded plastic container having a novel construction allowing
for significant label protection that is virtually indetectable,
improves the visual continuity of the container profile and
promotes the positive impact crated by the container product
label.
BACKGROUND OF THE INVENTION
[0002] Traditionally, containers used for the storage of products
for human consumption were made of glass. Typical desirable glass
characteristics include transparency, indeformability and perfect
label fixation. Nevertheless, because glass is fragile, easily
breakable and heavy, it has become cost prohibitative, due to the
high number of bottle breaks during handling. Moreover, as a result
of breakage preventive measures and weight, the transportation
expenses associated with glass greatly increases the cost of the
product.
[0003] Numerous commodities previously supplied in glass containers
are now being supplied in plastic containers, more specifically
polyester and even more specifically polyethylene terephthalate
(PET) containers. Manufacturers and fillers, as well as consumers,
have recognized that PET containers are lightweight, inexpensive,
recyclable and manufacturable in large quantities.
[0004] Manufacturers currently supply PET containers for various
liquid commodities, such as beverages. Manufacturers and fillers of
high acid content commodities as well as non-high acid content
commodities desire to supply their commodities in PET
containers.
[0005] Due to the relative high cost of PET material, even slight
increases in the weight of the material of the container will
result in an excessive increase in its cost, making it less
competitive in relation to the glass bottle, thereby resulting in
the infeasibility of such a solution to the problem. Accordingly,
reducing container weight, i.e., "lightweighting" the container,
thus providing a significant cost savings from a material
standpoint, is rather advantageous.
[0006] Typically, product label area protection has been
accomplished by incorporating structure in the sidewall of the
container. Primarily, this structure has taken the form of a ledge
above and below the product label area. While somewhat commercially
successful, these ledges create high stress points at their top and
bottom edges, especially at the upper and lower corners of these
ledges, and add weight and thus costs from a material standpoint.
These stress points weaken the area of the sidewall near these
edges, allowing the sidewall to collapse inwardly and/or fail
during handling of the container or when containers are stacked
together. These ledges also interrupt the visual continuity of the
container profile, taking away from the positive impact generated
by the product label.
[0007] One way to eliminate the concerns related to the above
mentioned stress points is to increase the thickness of the
container's sidewall, and specifically the ledges found in the
product label area. Such an increase also increases the material
cost for the container and the weight of the container, both of
which are unacceptable options.
[0008] Containers subject to the above-described stresses have
exhibited a somewhat limited ability to withstand loading forces
during filling, capping, labeling and stacking for transporting or
storage operations. As a result of this decreased container
rigidity, containers are less able to resist loads imparted when
the containers are stacked one upon another for storage and
shipping (as is readily understood, it is important to be able to
stack containers so as to maximize the use of shipping space). As a
result of this type of loading, or when the container is dropped,
the container can become deformed and undesirable to the consumer.
A solution to these types of problems is critical as it would
decrease the likelihood of a container becoming deformed and
undesirable to the consumer.
[0009] Thus, there is a need for an improved container which is
designed to accommodate and eliminate undesirable deformation in
the container yet which allows for lightweighting, provides label
protection that is virtually indetectable, improves the visual
continuity of the container and promotes the positive impact
created by the container product label.
[0010] With the foregoing in mind, a feature of the present
invention is to provide novel lightweight plastic containers which
provide virtually indetectable label protection and which are
resistant to unwanted distortion.
[0011] In another feature of the present invention, the blow
molded, lightweight plastic container provides improved visual
continuity of the container profile and promotes the positive
impact created by the container product label.
[0012] In another feature of the present invention, the blow
molded, lightweight plastic container provides improved label
protection and product label areas that minimize the stress points
on the corners of the product label area edges, by substantially,
if not completely, removing these stress points, and thereby
provides lower failure rates.
[0013] In function of the above mentioned qualities, associated
with its label protection and visual continuity, the proposed
container is an extremely inexpensive and efficient means for the
container user to promote its product, thus contributing to
reinforce the positive image of its company in the marketplace. It
is therefore a feature of this invention to provide such a
container.
SUMMARY OF THE INVENTION
[0014] Accordingly, this invention provides for a plastic container
which maintains aesthetic and mechanical integrity during any
subsequent handling having a structure that is designed to provide
label protection that is virtually indetectable, improves the
visual continuity of the container profile and promotes the
positive impact created by the container product label without
unwanted deformation.
[0015] In achieving the above and other objects, the present
invention includes a blow molded plastic container having an upper
portion, a sidewall portion and a base. The upper portion includes
an opening defining a mouth of the container. The sidewall portion
extends from the upper portion to the base. The sidewall portion
defined in at least part by a textured surface area, a product
label area and a label protection area. The textured surface area
and the label protection area in combination provides label
protection that is virtually indetectable.
[0016] Additional benefits and advantages of the present invention
will become apparent to those skilled in the art to which the
present invention relates from the subsequent description of the
preferred embodiment and the appended claims, taken in conjunction
with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0025] The following description of the preferred embodiment is
merely exemplary in nature and is in no way intended to limit the
invention, its applications or uses.
[0026] As discussed above, to promote product label area
protection, containers have been provided with ledges above and
below the product label area. Traditionally, these ledges add
structure, weight and thus costs from a material standpoint to the
sidewall of the container, and create stress points which weaken
the sidewall. These ledges further interrupt the visual continuity
of the container profile, lessening the positive impact generated
by the container product label.
[0027] Referring now to the drawings, there is depicted a blow
molded plastic container 10 embodying the principles and concepts
of the present invention. The container 10 of the present invention
illustrated in FIGS. 1-8 is particularly suited for packaging of
product, typically a liquid or beverage. The container 10 can be
filled by automated, high speed equipment known in the art. After
filling, the container 10 is sealed. The unique construction of the
container 10 enables it to provide improved label area protection,
improved visual continuity of the container profile and promote the
positive impact created by the container product label. While
designed for use in non-hot fill and non-thermal process
applications, it is noted that the container 10 is also acceptable
for hot-fill or thermal process applications. The teachings of the
present invention are more broadly applicable to a large range of
plastic containers.
[0028] The disclosed container structures can be made by stretch
blow molding from an injection molded preform of any of several
well known plastic materials. Accordingly, the plastic container 10
of the present invention is a blow molded container with an unitary
construction from a single or multi-layer material such as
polyethylene terephthalate (PET) resin. Alternatively, the plastic
container 10 may be formed by other methods and from other
conventional materials including, for example, polyethylene
napthalate (PEN), and a PET/PEN blend or copolymer. Plastic
containers blow molded with an unitary construction from PET
materials are known and used in the art of plastic containers, and
their general manufacture in the present invention will be readily
understood by a person of ordinary skill in the art.
[0029] As illustrated in FIGS. 1-4, the plastic container 10 of the
present invention generally includes a finish 12, a shoulder region
14, a sidewall portion 16 and a base 18. The container 10, as
illustrated in the figures, is in a shape commonly known and
described as a "flask". However, the teachings of the present
invention are more broadly applicable to a large range of plastic
container shapes and sizes.
[0030] The finish 12 of the plastic container 10 includes a portion
defining an aperture or mouth 20, a threaded region 22 and a
support ring 24. The aperture or mouth 20 allows the plastic
container 10 to receive a commodity while the threaded region 22
provides a means for attachment of a similarly threaded closure or
cap 26, shown in FIG. 4. Alternatives may include other suitable
devices which engage the finish 12 of the plastic container 10.
Accordingly, the closure or cap 26 functions to engage with the
finish 12 so as to preferably provide a hermetical seal for the
plastic container 10. The closure or cap 26 is preferably made from
a plastic or metal material conventional to the closure industry.
The support ring 24 may be used to carry or orient the preform (the
precursor to the plastic container 10) (not shown) through and at
various stages of manufacture. For example, the preform may be
carried by the support ring 24, the support ring 24 may be used to
aid in positioning the preform in the mold, or the support ring 24
may be used by an end consumer to carry the plastic container
10.
[0031] Integrally formed with the finish 12 and extending therefrom
is the shoulder region 14. The shoulder region 14 surrounds the
finish 12 and includes substantially flat surfaces which are
generally parallel to the container 10 support surface. If
anything, the shoulder region 14 extends slightly downward from the
finish 12. While a preferred shoulder region 14 is illustrated in
the figures, other shoulder region configurations can be utilized
with the novel features of the present invention.
[0032] The shoulder region 14 merges into the sidewall portion 16.
The shoulder region 14 provides a transition between the finish 12
and the sidewall portion 16. The sidewall portion 16 extends
downward from the shoulder region 14 to the base 18. The sidewall
portion 16 is constructed so as to provide label protection that is
virtually indetectable, improves the visual continuity of the
container profile and promotes the positive impact created by the
container product label. Because of the specific construction of
the shoulder region 14 and the sidewall portion 16, a lightweight
container exhibiting the above mentioned attributes can be
formed
[0033] The base 18 of the plastic container 10, which extends
inward from the sidewall portion 16, generally includes a chime 28,
a contact ring 30 and an inwardly, upwardly recessed portion 32.
The base 18 is coaxial with the shoulder region 14, and is
generally similar to the shoulder region 14 in shape and size. The
contact ring 30 is itself that portion of the base 18 which
contacts a support surface upon which the container 10 is
supported. As such, the contact ring 30 may be a flat surface or a
line of contact generally circumscribing, continuously or
intermittently, the base 18. The inwardly, upwardly recessed
portion 32 of the preferred embodiment of the invention is
connected to and extends generally inward and upward from the
lowermost portion of the chime 28. The inwardly, upwardly recessed
portion 32 preferably has a truncated-cone shape, but may
alternatively have a concave shape, a convex shape or any other
suitable shape. The base 18 functions to close off the bottom
portion of the plastic container 10 and, together with the shoulder
region 14 and the sidewall portion 16, to retain the commodity.
While a preferred base 18 is illustrated in the figures, other base
configurations can be utilized with the novel features of the
present invention.
[0034] The container 10, as illustrated in the figures, is in the
shape and size commonly known and described as a "flask".
Accordingly, sidewall portion 16 includes a front sidewall portion
34, a rear sidewall portion 36 and two side portions 38 located
diametrically opposite one another. As illustrated in FIG. 5, front
sidewall portion 34 has a radius of curvature R.sub.1, throughout
its arcuate extent. Similarly, rear sidewall portion 36 has a
radius of curvature R.sub.2, throughout its arcuate extent. The
radius of curvature R.sub.2 associated with the rear sidewall
portion 36 is greater than the radius of curvature R.sub.1
associated with the front sidewall portion 34. The front sidewall
portion 34 merges with and transitions into side portion 38 having
a radius of curvature R.sub.3, while the rear sidewall portion 36
merges with and transitions into side portion 38 having a radius of
curvature R.sub.4. The radius of curvature R.sub.4 associated with
the transition between the rear sidewall portion 36 and the side
portion 38 is greater than the radius of curvature R.sub.3
associated with the transition between the front sidewall portion
34 and the side portion 38. The front sidewall portion 34, the rear
sidewall portion 36 and the two side portions 38 extend
continuously in a longitudinal direction from the shoulder region
14 to the base 18. Together, the front sidewall portion 34, the
rear sidewall portion 36 and the two side portions 38 form a
continuous integral circumferential sidewall portion 16.
[0035] In order to provide label protection that is virtually
indetectable, improve the visual continuity of the container
profile and promote the positive impact created by the container
product label, the shoulder region 14 and the sidewall portion 16
of the container 10 of the present invention adopt a novel and
innovative construction.
[0036] To this end, the shoulder region 14, and the front sidewall
portion 34, the rear sidewall portion 36 and the two side portions
38 of the sidewall portion 16 include indentations 40, 42 and 44
formed therein. Indentations 40, 42 and 44 are generally polygonal
in shape and vary in size. The surface area of indentation 40 is
approximately between about 0.15 inch.sup.2 (96.77 mm.sup.2) to
about 0.09 inch.sup.2 (58.06 mm.sup.2), while the depth of
indentation 40 is approximately between about 0.02 inch (0.51 mm)
to about 0.04 inch (1.02 mm). The surface area of indentation 42 is
approximately between about 0.09 inch.sup.2 (58.06 mm.sup.2) to
about 0.04 inch.sup.2 (25.81 mm.sup.2), while the depth of
indentation 42 is approximately between about 0.02 inch (0.51 mm)
to about 0.04 inch (1.02 mm). The surface area of indentation 44 is
approximately between about 0.04 inch.sup.2 (25.81 mm.sup.2) to
about 0.03 inch.sup.2 (19.35 mm.sup.2), while the depth of
indentation 44 is approximately between about 0.02 inch (0.51 mm)
to about 0.04 inch (1.02 mm). Separating and defining indentations
40, 42 and 44 is web portion 46. The generally polygonal in shape
and varying in size indentations 40, 42 and 44, along with the web
portion 46, combine together to form textured patterned surfaces,
rendering a visual appearance of random "hammer" marks, as if the
shoulder region 14 and the sidewall portion 16 of the container 10
were hand made by a metal smith. As a result of the depth of
indentations 40, 42 and 44, web portion 46 appears to be
raised.
[0037] As illustrated in FIGS. 1 and 2, the front sidewall portion
34 of the sidewall portion 16 of the container 10 includes a
product label area 48. The product label area 48 illustrated is
generally smooth and generally rectangular in shape measuring
approximately 3.780 inches (96.012 mm) long and approximately 2.283
inches (57.988 mm) wide. While a preferred product label area 48 is
illustrated in the figures, other geometrical configurations can be
utilized with the novel features of the present invention. As
illustrated in FIG. 4, the rear sidewall portion 36 of the sidewall
portion 16 of the container 10 includes a product label area 50.
The product label area 50 illustrated is generally smooth and
generally rectangular in shape measuring approximately 3.0 inches
(76.2 mm) long and approximately 2.261 inches (57.429 mm) wide.
Similar to the product label area 48 on the front sidewall portion
34, the product label area 50 on the rear sidewall portion 36 can
be of any geometrical configuration. A label can be applied to
product label areas 48 and 50 using methods that are well known to
those skilled in the art, including adhesive methods.
[0038] The novel and innovative construction of the container 10
further includes an upper product label protection area 52 and a
lower product label protection area 54. As illustrated in FIG. 3,
the shoulder region 14 merges with and transitions into the upper
product label protection area 52 of the front sidewall portion 34
of the sidewall portion 16. Thereafter, the upper product label
protection area 52 merges with and transitions into the product
label area 48. Integrally formed with the product label area 48 and
extending downward therefrom is the lower product label protection
area 54. The lower product label protection area 54 of the front
sidewall portion 34 of the sidewall portion 16 then merges with and
transitions into the base 18. Thus, the upper product label
protection area 52 is located above the product label area 48,
while the lower product label protection area 54 is located below
the product label area 48.
[0039] Accordingly, as specifically illustrated in FIG. 8, the
upper product label protection area 52 exhibits a generally outward
arcuate shaped surface 56 extending downward from the shoulder
region 14 to the product label area 48. Similarly, the lower
product label protection area 54 exhibits a generally outward
arcuate shaped surface 58 extending upward from the base 18 to the
product label area 48. Generally, outward arcuate shaped surface 56
has a radius of curvature designated as R.sub.5. Generally, outward
arcuate shaped surface 58 has a radius of curvature designated as
R.sub.6. Typically, radius of curvature R.sub.5 of the generally
outward arcuate shaped surface 56 and radius of curvature R.sub.6
of the generally outward arcuate shaped surface 58 measure
approximately between about 1.969 inch (50 mm) to about 3.937 inch
(100 mm). The generally outward arcuate shaped surfaces 56 and 58,
individually can be described as bulges. While in combination with
the product label area 48, generally outward arcuate shaped
surfaces 56 and 58 can be described as defining a hourglass
silhouette.
[0040] In visual appearance, the application of the hammer like,
textured patterned surface of the front sidewall portion 34, having
indentations 40, 42 and 44 formed therein, of the container 10
serves to disguise and hide the radii of curvature R.sub.5 and
R.sub.6 associated with generally outward arcuate shaped surfaces
56 and 58, thereby, providing subtle, virtually indetectable or
hidden label protection. Accordingly, the visual appearance of the
container 10 is enhanced by the interrelationship between the
hammer like, textured patterned surface of the front sidewall
portion 34, having indentations 40, 42 and 44 formed therein, of
the container 10 with the generally outward arcuate shaped surface
56 of the upper product label protection area 52, the product label
area 48 and the generally outward arcuate shaped surface 58 of the
lower product label protection area 54, while at the same time
providing label protection that is subtle, virtually indetectable,
improving the visual continuity of the entire container 10 profile
and promoting the positive impact created by the container product
label.
[0041] While the above description constitutes the preferred
embodiment of the present invention, it will be appreciated that
the invention is susceptible to modification, variation and change
without departing from the proper scope and fair meaning of the
accompanying claims.
