Molded container with beaded neck
View Patent ↗A container having a neck that includes an upper sidewall defining an opening, a lower sidewall and a flange radially extending from the neck between said upper and said lower sidewall. Beads are disposed around an outer circumference of the neck on the flange at the junction of the flange and the upper or lower sidewall. The container can have a sidewall that is substantially rectangular in cross section. Insets can be formed between two adjacent panels in the container sidewall.
1. A container neck comprising:
a finish terminating in an opening;
a circumferential upper sidewall connected to said finish at an end opposite said opening;
a lower sidewall below said upper sidewall; and
a hollow annular flange extending radially outwardly between said upper and said lower sidewalls, wherein the flange includes undulations in a top surface thereof, at least a portion of the undulations extending radially outwardly and downwardly from said upper sidewall to strengthen the container neck.
2. The container neck of claim 1 , wherein said undulations comprise peaks and valleys.
3. The container neck of claim 2 , wherein said undulations have linear sides and a substantially triangular shape.
4. A container neck of claim 2 , comprising eight peaks.
5. The container neck of claim 2 , wherein said undulations are arcuate.
6. The container neck of claim 5 , wherein said undulations form an approximately sinusoidal wave at the point of connection with said upper sidewall.
7. The container neck of claim 1 , further comprising threads disposed on an outer surface of said finish.
8. The container neck of claim 1 , wherein said flange comprises a ledge extending beyond an outer periphery of said undulations.
9. The container neck of claim 1 , wherein the container is adapted for hot-fill processing.
10. A container comprising
a neck portion comprising
a finish terminating in an opening;
a circumferential upper sidewall connected to said finish at an end opposite said opening;
a lower sidewall below said upper sidewall; and
a hollow annular flange extending radially outwardly between said upper and said lower sidewalls, wherein the flange includes undulations in a top surface thereof, at least a portion of the undulations extending radially outwardly and downwardly from said upper sidewall to strengthen the neck portion;
a transition region extending from the neck portion to a tubular container sidewall portion; and
a base portion below said container sidewall portion.
11. The container of claim 10 , wherein said undulations are arcuate.
12. The container of claim 11 , wherein said undulations form an approximately sinusoidal wave at the point of connection with said upper sidewall.
13. The container of claim 10 , wherein said undulations are linear forming a triangular shape.
14. The container of claim 10 , further comprising threads disposed on an outer surface of said finish.
15. The container of claim 10 , wherein said undulations comprise peaks and valleys.
16. The container of claim 10 , wherein the container is adapted for hot fill processing.
17. The container of claim 10 , wherein said flange comprises a ledge extending beyond an outer periphery of said undulations.
18. The container of claim 15 , comprising eight peaks.
19. The container of claim 10 , said container sidewall portion comprising four substantially planar panels wherein opposite planar panels are substantially parallel.
20. The container of claim 19 , wherein the container sidewall portion comprises an inset between two adjacent planar panels.
21. The container of claim 19 , wherein said container sidewall portion comprises an arcuate panel connecting two adjacent planar panels.
22. The container of claim 21 , further comprising an inset in the arcuate panel between two adjacent panels.
23. The container of claim 22 , comprising two insets in arcuate panels that are diagonally disposed from one another.
24. The container of claim 10 , said container sidewall comprising an upper bumper and a lower bumper and an inset region between said upper bumper and said lower bumper.
