Containers having improved vacuum resistance
View Patent ↗Containers having improved vacuum-resistance and aesthetic features are provided. In a general embodiment, the present disclosure provides a container ( 10 ) having a substantially rectangular-shaped body including at least one cut-away portion ( 32 ) on a first side of the body. The cut-away portion includes a panel ( 34 ) that is intersected by a horizontal rib ( 36 ) that extends along an outer perimeter of the container in a substantially horizontal plane. The structural features of the present containers advantageously provide for improved vacuum-resistance and consumer gripping when compared to similar containers currently on the market.
1. A plastic container comprising:
a mouth configured for liquid to be introduced into and removed from the container through the mouth; and
a substantially rectangular-shaped body comprising a first cut-away portion on a first side of the body, the first cut-away portion having a first panel that is intersected by a first rib that extends along an outer perimeter of the container in a substantially horizontal plane, the first panel comprises two indentations formed on opposite sides of the first rib, the first rib comprises end portions on the substantially horizontal plane that intersect sides of the first panel and comprises a middle portion that varies in height from the substantially horizontal plane and is between the end portions, and the first rib curves in a vertical direction such that a vertical distance from the middle portion to the mouth is different than a vertical distance from the end portions to the mouth.
2. The container of claim 1 , wherein the two indentations are complimentary shaped relative to each other.
3. The container of claim 1 , wherein the two indentations are complimentary bean-shaped portions formed by the first rib.
4. The container of claim 1 , wherein the first rib is one of an interrupted rib or a fully circumferential rib.
5. The container of claim 1 , wherein the body comprises a second panel on a second side of the body, wherein the second panel is located in the same horizontal plane as the first panel.
6. The container of claim 1 comprising a shoulder between the mouth and the body, the shoulder comprising four faces arranged in a square pyramid frustum shape, at least one of the four faces comprising a second cut-away portion having a second panel intersected by a second rib that is an interrupted horizontal rib.
7. The container of claim 1 , wherein the first side comprises a plurality of the cut-away portions.
8. The container of claim 1 , wherein the container comprises a volume ranging from about 100 mL to about 5000 mL.
9. A plastic container comprising:
a neck defining a mouth of the container; and
a body comprising a plurality of horizontal ribs extending along an outer perimeter of the container, each of the plurality of horizontal ribs is located in a different horizontal plane, the plurality of horizontal ribs comprises a first rib located intermediate two complimentary-shaped indentations, the first rib comprises end portions on the corresponding horizontal plane that intersect sides of the indentations and comprises a middle portion that varies in height from the substantially horizontal plane and is between the end portions, and the first rib curves in a vertical direction such that a vertical distance from the middle portion to the mouth is different than a vertical distance from the end portions to the mouth.
10. The container of claim 9 , wherein each of the plurality of horizontal ribs fully extends around the circumference of the body.
11. The container of claim 9 , wherein every other horizontal rib is located intermediate two complimentary-shaped indentations.
12. The container of claim 9 , wherein the complimentary-shaped indentations are bean-shaped panels.
13. The container of claim 9 , wherein the body comprises four sides, and each side comprises a plurality of horizontal ribs located intermediate two complimentary-shaped indentations.
14. The container of claim 9 , wherein the body comprises at least one wall having first and second opposing inwardly-sloped portions forming an elongated middle section of the container.
15. The container of claim 14 , wherein the elongated middle portion of the container has a reduced cross-section compared to vertical portions of the container.
16. The container of claim 14 , wherein the first and second opposing inwardly-sloped portions meet at one of the horizontal ribs.
17. The container of claim 9 having a weight ranging from about 23 g to about 27 g.
18. A plastic container comprising:
a neck that defines a mouth of the container; and
a substantially rectangular shaped body comprising a first plurality of horizontal ribs extending along an outer perimeter of the container, each rib of the first plurality of horizontal ribs is located in a different horizontal plane, and a second plurality of horizontal ribs extending along an outer perimeter of the container, each of the second plurality of horizontal ribs is located in a different horizontal plane and located intermediate two complimentary-shaped indentations, each of the first plurality of horizontal ribs alternates in a vertical direction with each of the second plurality of horizontal ribs, each of the second plurality of ribs comprises end portions on the corresponding horizontal plane that intersect sides of the indentations and comprises a middle portion that varies in height from the substantially horizontal plane and is between the end portions, and each of the second plurality of horizontal ribs curves in a vertical direction such that a vertical distance from the middle portion to the mouth is different than a vertical distance from the end portions to the mouth.
19. The container of claim 18 , wherein each of the first plurality of horizontal ribs has a greater height than each of the second plurality of horizontal ribs.
20. The container of claim 9 , comprising a first panel comprising the two complimentary-shaped indentations, and the end portions of the first rib intersect sides of the first panel in the same horizontal plane relative to each other.
