Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Patent Application Ser. No. 60/783,141 for a FILLED AND SEALED BAG
HAVING EASY POUR SPOUT AND METHOD OF MAKING SAME, filed on Mar. 16,
2006, which is hereby incorporated by reference in its
entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates to the packaging for particulate
material such as ready-to-eat ("RTE") cereal. More specifically,
this invention is particularly useful in the form of a bag-in-a-box
with a re-closable bag.
[0004] 2. Description of Related Art
[0005] The use of a bag and or of a cartons with liner bag for
particulate products like RTE cereal is well known. Such cartons
are usually formed from a blank of paperboard or similar material
comprising sidewalls with top and bottom flaps. The liner is a
plastic or coated paper bag which holds the particulate product.
The liner can be filled and sealed before or after being placed
inside the open carton. The flaps of the carton are then folded and
sealed.
[0006] Gaining access to the contents of such cartons involves
breaking the seal between the top flaps of the carton and pulling
open the sealed liner bag. As will be appreciated by anyone who has
opened this type of bag, they do not always open neatly and many
times can tear in ways that make resealing difficult. Difficult and
incomplete sealing can lead to a loss of freshness of the product.
RTE cereal. For example, the particulate has a low moisture content
and readily absorbs moisture from the air, leading to a loss of
crispness.
[0007] Once opened, and as the contents are depleted, the liner bag
and its contents slide and shift positions in the carton which can
cause the opened portion of the liner to become misaligned with the
box opening thereby hindering dispensing of product from the
carton. This also causes product to drop between the carton and the
liner.
SUMMARY OF THE INVENTION
[0008] In summary, the invention is an article of commerce
comprising a bag containing a quantity of particulates. The bag
includes a sidewall encircling a longitudinal axis and extending
along the axis between a bottom closed end and a top closed end.
The opposite sides of the sidewall are brought together to form the
bottom closed and the top closed end. Both of the bottom and top
closed ends extend acutely with respect to the axis such that the
bag is parallelogram-shaped in a plane containing the axis and the
bottom closed end and the top closed end.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
[0017] The present invention provides a unique solution to the
opening and closing problems encountered with traditional bags and
particularly traditional bags in boxes. This unique solution is
obtained at little or even no additional cost in equipment,
material or labor.
[0018] Referring now to the figures of the application, the
exemplary embodiment of the invention includes a bag 10 containing
a quantity of particulates 12. A portion of the bag 10 is cut-away
in FIG. 1 to reveal the particles. In the exemplary embodiment of
the invention, the particles are RTE cereal pieces. But in
alternative embodiments of the invention, the particles can
encompass large bulk packaged pieces as well as very small bulk
packaged pieces. Examples of smaller fill materials include, but
are not limited to, the following: agricultural products like
seeds, rice, grains, vegetables, fruits; chemical products like
fine chemicals, pharmaceuticals, raw chemicals, fertilizers;
plastics like plastic resin pellets, plastic parts, rejected
plastic parts, machined plastic parts; cereals and cereal products
such as wheat; a variety of machined parts of all sorts; wood
products like wood chips, landscaping material, peat moss, dirt,
sand, gravel, rocks and cement. The present invention also finds
utilization in bulk packaging of larger fill material including,
but not limited to: prepared foods; partially processed foods like
frozen fish, frozen chicken, other frozen meats and meat products;
manufactured items like textiles, clothing, footwear; toys like
plastic toys, plastic half parts, metallic parts, soft toys,
stuffed animals, and other toys and toy products. All of these
types of materials and similar bulk packaged materials are intended
to be encompassed in the present specification and claims by this
phrase.
[0019] The bag 10 can be made of paper or plastic. The bag 10 can
be made from any material now known or subsequently developed that
is operable to contain particles.
[0020] The bag 10 includes a sidewall 14 encircling a longitudinal
axis 16 and extending along the axis 16. The sidewall 14 can be
continuous or can include seam, such as shown when comparing FIGS.
2 and 6. FIG. 6 shows a seam 36. The bag 10 extends between a
bottom closed end 18 and a top closed end 20. Opposite sides 26, 28
of the sidewall 14 are brought together to form the bottom and top
closed ends 18, 20. Both of the bottom and top closed ends 18, 20
extend acutely with respect to the axis 16 such that the bag 10 is
parallelogram-shaped in a plane containing the axis and the bottom
closed end 18 and the top closed end 20. This plane is shown in
FIG. 1, revealing the two acute angles 22 and 24.
[0021] The top closed end 20 of the exemplary bag 10 can be opened
by separating the opposite sides 26, 28 of the sidewall 14. FIG. 3
shows the bag 10 partially opened. The bag 10 can be opened without
tearing the sidewall 14. As a result, the bag 10 is re-closable.
FIGS. 4 and 5 show two view of the bag 10 in a re-closed
condition.
[0022] The structure of the exemplary bag 10 results in a pour
spout being defined when the top end 20 is opened. The exemplary
bag 10 is also structured to enhance the control over which the top
end 20 is opened. Specifically, the exemplary top end 20 is defined
by dual seal zones. In other words, the top end 20 is variably
sealed. As best shown schematically in FIG. 6, the top closed end
20 extends transverse to the axis 16 (shown in FIG. 1) between a
first end 30 disposed relatively closer to the bottom closed end 18
and a second end 32 disposed relatively further from the bottom
closed end 18. A first adhesive 34 disposed between the opposite
sides 26, 28 along a first portion of the top closed end 20. A
second adhesive 38 disposed between the opposite sides 26, 28 along
a second portion of the top closed end 20. The first adhesive 34
defines a greater adhesiveness that the second adhesive 38 such
that the first portion requires a greater force to open than the
second portion. In other words, an amount of separating force
required to open the top closed seal 20 is different at the first
and second ends 30, 32. Specifically, in the exemplary embodiment
of the invention, the amount of separating force required to open
the top closed seal 20 is greater at the second end 32 than at the
first end 30.
[0023] A bag according to the present invention can also be used
with or without a box or carton. The exemplary article of commerce
also includes a carton 40 having a sidewall 42 and bottom wall 44.
The sidewall 42 can continuous or be formed with a seam. The
sidewall 42 can be formed as a single piece (with or without a
seam) or formed from a plurality of discrete pieces. The sidewall
42 encircles the axis 16 and extends along the axis 16 between a
top end 46 and a bottom end 48. The bottom wall 44 closes the
bottom end 48 to cooperate with the sidewall 42 to define a
substantially enclosed cavity. The bag 10 is disposed in the
cavity. The carton 40 is further defined as being substantially
rectangular in a plane containing the axis 16 and the bottom closed
end 18 and the top closed end 20. The carton 40 can be formed from
plastic or paperboard. The carton 40 can include integral closing
structures or features, such as flaps, or can be engaged by a
separate lid or cover.
[0024] Indicia may be included on the pouring spout or carton to
provide instructions for opening.
[0025] FIG. 7 schematically shows a production line 50 for forming
the exemplary bag 10. In an exemplary method for making the bag 10,
a web 52 of folded material is drawn off of a roll 54 in a first
direction represented by arrow 56 along the production line 50. A
sealing bar 58 is disposed along the production line 50 at an acute
angle 60 to the first direction 56. A cutting bar 62 is also
disposed along the production line 50 at an acute angle 64 to the
first direction 56. The cutting bar 62 can be a dual purpose
device, cutting and sealing the web 52 to form the bag 10.
Likewise, the bar 58 can be a dual purpose device. The bars 58, 62
are space from one another along the production line 50. The
production line 50 is flexible in that, if rectangular bags are
desired, the bars 58, 62 can be rotated to be perpendicular to the
direction 56.
[0026] While the invention has been described with reference to an
exemplary embodiment, it will be understood by those skilled in the
art that various changes may be made and equivalents may be
substituted for elements thereof without departing from the scope
of the invention. In addition, many modifications may be made to
adapt a particular situation or material to the teachings of the
invention without departing from the essential scope thereof.
Therefore, it is intended that the invention not be limited to the
particular embodiment disclosed as the best mode contemplated for
carrying out this invention, but that the invention will include
all embodiments falling within the scope of the appended
claims.
