Abstract
A hazardous material shipping container comprises a shell having a first threaded portion at a first end thereof, a closed second end opposite the first end, inwardly extending ribs, and outwardly extending flutes, wherein the ribs and flutes are disposed between the first end and the second end. A cushioning material is inside the shell, and a cap has a second threaded portion adapted to mate with the first threaded portion and a recess on a lower surface wherein the recess is adapted to receive an upper portion of a material container.
Description
- The present application claims the benefit of
U.S. Provisional Patent Application No. 63/144,758, filed February 2, 2021 - The present subject matter relates to containers, and more particularly to a container for shipping hazardous materials.
- A known shipping container for shipping hazardous materials that are stored in, for example, an inner material container comprising a plastic or glass bottle, is similar to a conventional paint can having a center cover that fits over a center portion and has an outer rim that wedges into a circumferential groove of the container proper. In addition, such a "paint can" container includes a plastic ring that fits over the outer periphery of the container so that the container can withstand high pressures within the container and can survive drops and rough handling in transit. While the container may be usable to protect against an accidental release of the hazardous material and/or damage to the inner container during shipping, such a container suffers from the disadvantage that the plastic ring is difficult to remove when the contents are to be retrieved from the container. This disadvantage can render use of the shipping container inconvenient and undesirable.
- According to an aspect, a hazardous material shipping container comprises a shell having a first threaded portion at a first end thereof, a closed second end opposite the first end, inwardly extending ribs, and outwardly extending flutes, wherein the ribs and flutes are disposed between the first end and the second end. A cushioning material is inside the shell, and a cap has a second threaded portion adapted to mate with the first threaded portion and a recess on a lower surface wherein the recess is adapted to receive an upper portion of a material container.
- Other aspects and advantages will become apparent upon consideration of the following detailed description and the attached drawings wherein like numerals designate like structures throughout the specification.

Further, four sets of spaced portions 58 (FIGS. 14, 15 , and21 ) of anouter surface 60 of thecap 14 may also include outwardly extending portions or lugs separated by grooves (FIG. 20 ) defining serrations 62 (FIGS. 14 and 15 ) to promote gripping of thecap 14 by a user during threading and unthreading thereof. - While the
first ribs 32 are illustrated as being substantially or fully identical to one another in shape and spacing and the bumps orflutes 36 are illustrated as being substantially or fully identical to one another in shape and spacing, this need not be the case inasmuch as one or more of theribs 32 may be differently shaped and/or differently spaced with respect to the remaining rib(s) 32, as may one or more of the bumps orflutes 36 with respect to the remaining bumps orflutes 36. Also, as seen inFIG. 7 , eachfirst rib 32 is illustrated as being equally spaced between adjacent bumps orflutes 36. although this need not be the case inasmuch as theribs 32 may be disposed at other locations relative to the bumps orflutes 36. Also, eachrib 32 and bump orflute 36 may extend the full height of theshell 12, exclusive of thethreads 18, or may only extend a portion of such height. - Still further, although the
first ribs 32 and bumps orflutes 36 are shown as having constant inwardly extending and outwardly extending dimensions, respectively, along the height of theshell 12 exclusive of the threads 18 (neglecting taper due to the presence of the draft angle), respectively, one or more of theribs 32 and/or bumps orflutes 36 may have varying inwardly extending and outwardly extending dimensions, respectively, along the height of theshell 12. - While inner and
outer bottom surfaces 42, 43, respectively, of theshell 12 are illustrated as being flat (i.e., planar), a series of bumps, nubs, or other features (not shown) may be provided on either or bothsurfaces 42, 43 to provide shock absorption if theshell 12 is dropped. - Other features and/or recesses may be provided on the
shell 12 and/orcap 14 to provide further shock protection. An alternative or additional enclosure for theglass container fabric bag 28 may be provided. - Another
cap 14b is illustrated inFIG. 21 that is usable with theshell 12 in lieu of thecap 14. Thecap 14a includes radially-extending ribs of constant height in place of some or all of theribs 40. - Thus, in the illustrated embodiment, radially extending
ribs 40a are substituted for every other radial gusset comprising arib 40. Thecap 14b is otherwise identical to thecap 14 with the exception of a shallowblind bore 100 disposed at the center of thecap 14b and is threaded onto theshell 12 in use as seen inFIGS. 5 and5A . - The container disclosed herein is sufficiently strong and resilient to pass drop tests and other federally-mandated requirements and may be capable of qualifying for a special permit from the Department of Transportation that would allow the container to be shipped without the need for further protective packaging.
