This disclosure relates generally to plastic containers configured to store and/or transport liquids, including chemicals such as organic peroxides.
Containers used for storing and transporting chemicals, such as organic peroxides, have strict performance requirements in order to ensure safety during transportation due to the volatile nature of the contents of those containers. While known product configurations satisfy those requirements by meeting certain drop test ratings, there are certain limitations to the features included in those designs.
While known configurations are able to meet industry required drop test ratings, those containers provide inadequate gripping structures and are also difficult to fully drain. The limitations of known configurations present safety concerns both in relation to lifting the container to pour and fully draining the container at the end of its use. Some containers are not readily manipulated by a user. In addition, some containers are not readily stackable or storable in multiple stacking configurations. The inventors of the present application provide a container that addresses a need for better containers for chemicals, which is particularly suitable for organic peroxides, but which may be used to store and/or transport a variety of chemicals. The container of the present disclosure provides a container that is configured to provide enhanced emptying ability. This enhanced emptying ability is achieved through the location and design of the main pouring spout, the configuration of the neck and shoulders of the front top of the container, and the contours of the bottom of the container, the combination of which minimizes the need for the user to pierce the bottom of the container multiple times in order to achieve complete drainage. In one aspect, the shoulders (or front surface portion) of the container are sloped in the downward direction. The container also includes a top in-line elongated handle portion. The container itself may have a square, or substantially square configuration allowing for stackability and providing for maximum usage of available space on a square shipping pallet. The container may be configured to meet current UN ratings, especially for organic peroxides. The term “square” as used herein means that the container is configured such that the length and width of the bottom surface are substantially equal. The container may comprise HDPE.
According to an aspect of the disclosure, a plastic container configured to store and/or transport liquids, such as organic peroxides, includes a top portion having a vent spout that defines a circular vent recess that has a vent center. The vent spout extends longitudinally along a first axis, the first axis extending through the vent center. The top portion also includes a main spout that defines a circular main recess having a main center. The main spout extends longitudinally along a second axis, the second axis extending through the main center. The main spout has a top end and a bottom end of the main spout, the top end being opposite the bottom end along the second axis such that the bottom end is disposed in a downward direction relative to the top end along the second axis. The top portion also includes a front surface portion having a slanted face that extends in the downward direction and in a forward direction. The forward direction is defined by a line that extends from the first axis to the second axis, perpendicular to the first axis and second axis. The front surface also includes a lip that extends radially from the second axis away from the slanted face in the forward direction. Additionally, the top portion includes an integrated handle that is elongate along the line that extends between the first axis and the second axis. The top panel defines a maximum container length along the line and the handle defines a maximum handle length along the line. The maximum container length is approximately twice the maximum handle length. The container also includes a base portion. The base portion has an interior surface and an exterior surface. The exterior surface defines a handle recess. Additionally, the container includes a sidewall that extends between the top portion and the base portion.
According to another aspect of the disclosure, a plastic container configured to store and/or transport liquid, such as organic peroxide includes a top portion having a vent spout that defines a circular vent recess that has a vent center. The vent spout extends longitudinally along a first axis, the first axis extending through the vent center. The top portion also includes a main spout that defines a circular main recess having a main center. The main spout extends longitudinally along a second axis, the second axis extending through the main center. The main spout has a top end and a bottom end of the main spout, the top end being opposite the bottom end along the second axis such that the bottom end is disposed in a downward direction relative to the top end along the second axis. The top portion also includes a front surface portion having a slanted face that extends in the downward direction and in a forward direction. The forward direction is defined by a line that extends from the first axis to the second axis, perpendicular to the first axis and second axis. The front surface also includes a lip that extends radially from the second axis away from the slanted face in the forward direction. Additionally, the top portion includes an integrated handle that is elongate along the line that extends between the first axis and the second axis. The container also includes a base portion. The base portion has an interior surface and an exterior surface. The exterior surface defines a handle recess. Additionally, the container includes a sidewall that extends between the top portion and the base portion.
According to a third aspect of the disclosure, a plastic container configured to store and/or transport liquid, such as organic peroxide includes a top portion having a vent spout that defines a circular vent recess that has a vent center. The vent spout extends longitudinally along a first axis, the first axis extending through the vent center.

The foregoing summary, as well as the following detailed description of illustrative embodiments of the dual handle container of the present application, will be better understood when read in conjunction with the appended drawings. For the purposes of illustrating the dual handle container of the present application, there is shown in the drawings illustrative embodiments. It should be understood, however, that the application is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Aspects of the disclosure will now be described in detail with reference to the drawings, wherein like reference numbers refer to like elements throughout, unless specified otherwise. Certain terminology is used in the following description for convenience only and is not limiting.
Referring to
The container 10 includes a top portion 20, a base portion 40, and a sidewall 50 that extends between the top portion 20 and the base portion 40. The top portion 20 includes a vent spout 22 that defines a circular vent recess 24 having a vent center VC. In some embodiments, vent recess 24 has a diameter of at least 22 millimeters. The vent spout 22 extends longitudinally along a first axis A, the first axis A extending through the vent center VC. The vent spout 22 has an outer surface that defines an attachment mechanism for a vent cap (not shown). In some embodiments, the attachment mechanism on the vent spout may be threads that mate with threads on an internal surface of the vent cap.
The top portion 20 further includes a main spout 26 that defines a circular main recess 28 having a main center MC. In some embodiments, circular main recess 28 has a diameter of no more than 63 millimeters, such as a diameter of 61 millimeters. In other embodiments, circular main recess 28 has a diameter of 70 millimeters. The diameters of vent recess 24 and main recess 28 may be adjusted relative to each other to optimize pourability of the contents of the container 10. The diameters of vent recess 24 and main recess 28 may also be adjusted to optimize drop test ratings.
The main spout 26 extends longitudinally along a second axis B that extends through the main center MC from a top end 26a of the main spout 26 to a bottom end 26b of the main spout 26. The top end 26a is opposite the bottom end 26b along the second axis B such that the bottom end 26b is disposed in a downward direction D relative to the top end 26a along the second axis B. The downward direction D extends in the opposite direction to an upward direction U along axis B. Main spout 26 may be disposed relatively close to a front portion of sidewall 50 such that a distance SD measured between main center MC and the front portion of the sidewall is relatively small. For example, distance SD may be 1.7 inches (4.3 cm), or approximately 1.7 inches (4.3 cm). The main spout 26 has an outer surface that defines an attachment mechanism for a main cap 60. In some embodiments, the attachment mechanism on the main spout 26 may be threads that mate with threads on an internal surface 62 of the main cap 60. The main spout may also include an annular ring 27 disposed at its bottom end 26b having a ratcheted surface that is used to break a security seal from the main cap 60 when the main cap 60 is first removed by twisting from the main spout 26.
The top portion 20 also includes beveled shoulders 35 that extend upward and away from the bottom end 26b of the main spout relative to axis B. A front surface portion 30 having a slanted face 32 that extends in the downward direction and in a forward direction F is proximate to beveled shoulders 35 such that the bottom end 26b of the main spout is partially encircled by the beveled shoulders 35 and the front surface portion 30. The forward direction F is defined by a line L that extends from the first axis A to the second axis B, perpendicular to the first axis A and second axis B. A rearward direction R extends opposite to the forward direction F along line L. The front surface portion 30 includes a lip 34 that extends radially from the second axis B away from the slanted face 32 in the forward direction F. Lip 34 has a front surface 34a that protrudes from slanted face 32 parallel or approximately parallel to second axis B.
Front surface 34a is configured to extend at approximately the same radius r (shown in
The top portion 20 has an integrated handle 36 that is elongate along the line L that extends between the first axis A and the second axis B. With reference to
The top portion 20 also defines a top handle recess 37 around the integrated handle 36 and includes a recess base 33 directly below the integrated handle. The top handle recess 37 is configured to fit a gloved hand of a user. Specifically, relative to prior art configurations, handle 36 has an inner surface 36x that defines a longer inner handle length IHL, as measured between a forward-most point 36a of the handle inner surface 36x and a rearward-most point 36b of the handle inner surface 36x. For example, inner handle length IHL may be 3.5 inches (8.9 cm), or approximately 3.5 inches (8.9 cm), such that the inner handle length IHL is 32% or approximately or at least 32% of the maximum container length CL. Additionally, relative to prior art configurations, handle 36 and handle recess 37 defines a greater handle clearance distance HCD as measured between an upper-most point of inner surface 36x of the handle 36 and the recess base 33 along a line that is parallel to axis B is greater so as to provide adequate space for the relatively larger size of the user's hand when covered with safety equipment including gloves. For example, the handle clearance distance HCD may be 1.5 inches (3.8 cm), or approximately 1.5 inches (3.8 cm). In this example, if the overall maximum container height CH is 14.9 inches (37.8 inches), or approximately 14.9 inches (37.8 cm), the handle clearance distance HCD is 10%, or approximately or at least 10% of the container height CH. Moreover, in order to provide for an increased handle clearance distance HCD, recess base 33 may be disposed below main spout bottom end 26b.
The top portion 20 also includes structural recesses 39 that enhance the structural integrity of the container 10 and also reduce the material needed to form the container 10. Recesses 39 may also function to enhance gripping of the container by the gloved user.
With reference to
With reference to
Exterior surface 44 also defines stacking flanges 48. Stacking flanges 48 are configured to mate with stacking notches 38 that are defined by the top portion 20 so as to enhance the stackability of containers 10. Stacking flanges 48 and stacking notches 38 may be substantially square in shape. For example, multiple containers 10 may be stacked on one another for transportation on a pallet (not shown). Flanges 48 and notches 38 mate with each other so as to minimize lateral movement of a first container 10 relative to a second container 10 stacked above or below the first container. While the embodiment shown in
Sidewall 50 extends between the top portion 20 and the base portion 40. Sidewall 50 connects to the top portion 20 and the base portion 40 at annular structural ribs 52, 54, respectively. Structural ribs 52, 54 enhance the structural integrity of the container 10.
