Multi-sided spiraled plastic container
View Patent ↗A multi-sided spiraled plastic container for liquid, flowable, and squeezable products may be suitable for use with food or beverage products packaged by traditional hot-fill processes. The container includes an open top through which the container is adapted to be filled, and a body portion having a shoulder section, which extends downwardly from the open top towards a closed base portion. The body portion has a plurality of vacuum panel pairs which are disposed in a spiral fashion about the body portion and configured for contributing to a superior top load strength of the container.
1. A polymeric container, comprising:
an open top through which the polymeric container is adapted to be filled;
a body portion having a shoulder section, which extends downwardly from said open top towards a closed base portion;
said body portion having a plurality of vacuum panel pairs which are disposed in a spiral fashion about said body portion and configured for contributing to a superior top load strength of the polymeric container, wherein each vacuum panel of said plurality of vacuum panel pairs comprises an outward curve;
wherein said vacuum panel pairs spiral in a first direction to a midpoint of the container and in a second direction to said base portion of the container; and
a relatively rigid transitional wall between adjacent vacuum panel pairs, wherein each vacuum panel midpoint is diametrically opposed to a corresponding transitional wall.
2. The polymeric container according to claim 1 , wherein said vacuum panel pairs spiral at about 72 degrees.
3. The polymeric container according to claim 2 wherein said vacuum panel pairs spiral at about 36 degrees in the first direction and about 36 degrees in the second direction.
4. The polymeric container according to claim 3 , wherein said first and second direction are opposite.
5. The polymeric container according to claim 1 , wherein said vacuum panel pairs spiral at about 90 degrees.
6. The polymeric container according to claim 5 wherein said vacuum panel pairs spiral at about 45 degrees in the first direction and about 45 degrees in the second direction.
7. The polymeric container according to claim 1 , wherein said vacuum panel pairs spiral at about 60 degrees.
8. The polymeric container according to claim 7 wherein said vacuum panel pairs spiral at about 30 degrees in the first direction and about 30 degrees in the second direction.
9. The polymeric container according to claim 1 , wherein said vacuum panel pairs spiral at about 52 degrees.
10. The polymeric container according to claim 9 wherein said vacuum panel pairs spiral at about 26 degrees in the first direction and about 26 degrees in the second direction.
11. The polymeric container according to claim 1 , wherein said vacuum panel pairs spiral at about 45 degrees.
12. The polymeric container according to claim 11 wherein said vacuum panel pairs spiral at about 22 to 23 degrees in the first direction and about 22 to 23 degrees in the second direction.
13. The polymeric container according to claim 1 , comprising an odd number of vacuum panel pairs.
14. The polymeric container according to claim 13 , comprising five vacuum panel pairs.
15. A polymeric container, comprising:
an open top through which the polymeric container is adapted to be filled;
a body portion having a shoulder section, which extends downwardly from said open top towards a closed base portion;
said body portion having:
a plurality of vacuum panel pairs which are disposed in a spiral fashion about said body portion, wherein each vacuum panel of said plurality of vacuum panel pairs comprises an outward curve; and
a relatively rigid transitional wall between adjacent vacuum panel pairs, wherein each vacuum panel midpoint is diametrically opposed to a corresponding transitional wall; and
wherein said vacuum panel pairs spiral in a first direction to a midpoint of the container and in a second direction to said base portion of the container.
16. A polymeric container, comprising:
an open top through which the polymeric container is adapted to be filled;
a body portion having a shoulder section, which extends downwardly from said open top
towards a closed base portion;
said body portion having:
an odd number of vacuum panel pairs which are disposed in a spiral fashion about said body portion, wherein each vacuum panel of said plurality of vacuum panel pairs comprises an outward curve; and
a relatively rigid transitional wall between adjacent vacuum panel pairs, wherein each vacuum panel midpoint is diametrically opposed to a corresponding transitional wall;
wherein said vacuum panel pairs spiral in a first direction to a midpoint of the container and in a second direction to said base portion of the container.
