Definitions

  • the tight head drum is known to be more secure and less expensive than an open head drum.
  • the head On a tight head drum, the head is an integral part of the drum construction — both ends are flanged and permanently sealed.
  • the open head drum relies on a rather large, heavy duty closing ring and a gasket in order for it to pass the necessary tests to ship hazardous materials.
  • the container can include a tight head form with a “lid” opening.
  • this opening allows the liner to be more easily installed as well as extracted from the drum or container while maintaining a high degree of performance.
  • the opening in the drum can be closed off with a cover or “lid” that has a much smaller closing ring than is currently used on a full open head drum. This can result in a lower cost than a full open head drum because the closing ring is much smaller and doesn’t have to be as heavy duty. It is also much easier to assemble a smaller cover than a full lid for an open head drum.
  • a container can include a body and an upper head and a lower bottom.
  • the container can also include a first opening in the upper head.
  • the first opening can have a diameter smaller than the diameter of the body.
  • the first opening can include a rim extending from the upper head.
  • the container can further include a second opening in the upper head, the second opening comprising a vent.
  • the rim of the first opening can include an annular bead.
  • the first opening can include an opening between about 3 inches and about 12 inches.
  • the container can include a fifty five (55) gallon drum.
  • the container can further include a cover configured to couple to the annular bead.
  • an outer rim of the cover can include an engagement groove for the annular bead of the rim.
  • the cover can couple to the annular bead with a closing ring.
  • the cover can include a bung opening fitting.
  • the container can further include a liner disposed within the container. The liner can be removable and/or replaceable.
  • a tight head drum can include a cylindrical body with a closed bottom end and a top end.
  • the top end can include an opening having a diameter smaller than the cylindrical body.
  • the opening can be sealed with a lid, the lid coupled to the opening with a closing ring.
  • the opening can be an opening between about 3 inches and about 12 inches.
  • the tight head drum can further include a liner disposed within the drum, the liner can include a material resistant to hazardous materials.
  • the top end can further include a vent opening.
  • the lid can include a steel cover.
  • the lid can further include an opening between about 3 inches and about 12 inches. The opening can be configured to be sealed with a drum plug.
  • a lidded drum can include a closing ring for fastening a drum lid on a primary opening of the drum.
  • the primary opening can include an annular bead rim extending from an upper surface of the drum.
  • the lidded drum can include a secondary opening defined by the upper surface of the drum.
  • the secondary opening can include a smaller diameter than the primary opening.
  • the closing ring can include an engagement groove for engaging the annular bead of the outer rim of the lid.
  • the primary opening can include a circular diameter and the drum lid can define an opening having a diameter smaller than the primary opening.
  • FIG. 1 is a cross-sectional view of a container, according to some embodiments.
  • FIG. 2 is a top view of the container of FIG. 1.
  • FIG. 3 is an exploded cross-section view of a portion of a container, according to some embodiments.
  • a storage and transport drum assembly can include a liner disposed within the drum.
  • the container and liner assembly presents a hybrid solution between a tight head drum and an open head drum.
  • the container can include a tight head form with a first opening in the upper or top portion of the drum. In some examples, this first opening allows the liner to be more easily installed as well as extracted from the drum or container; while maintaining a high degree of performance.
  • the opening in the drum can be closed off with a cover or lid that has a much smaller closing ring than is currently used on a full open head drum.
  • a container may include a tight head drum with a first opening in the top or upper head and a liner may be placed into the container, the container assembly may then be filled with storage material (e.g., a hazardous waste). A lid or cover may be placed over the liner and the opening in the container and secured thereto.
  • storage material e.g., a hazardous waste
  • the lid may be secured with an adhesive, via friction or a snap fit, an internal or external threaded connection, a gasket and latched connection, with toothed or other biting-type features, or other connection systems.
  • the container may thus store the material to be shipped or placed in storage.
  • the lid or opening cover may be removable and resealable such that some or all of the material in the container may be accessed and withdrawn from the container for use.
  • the liner may be removable and/or replaceable. Where only a portion of the material is withdrawn, the lid may be replaced, thereby allowing for further storage and/or shipping and/or handling of the container while preserving the rest of the material for later use or continuing to isolate the material from the environment.

  • the body 102 may be further configured to support the contents of the container 100 with respect to any outwardly or inwardly directed forces imparted on the container 100 by the contents or otherwise.
  • the body 102 can include a standard diameter of a 55 gallon drum, or about 22.5 inches.
  • the lower bottom 104 can be sealed to the body 102 by a weld, connected with a closing ring and/or gasket, or be monolithically or integrally formed from a single piece of material formed with the body 102.
  • the lower bottom 104 may include a generally flat outer surface for resting the container 100 on a surface and may have a thickness and a material strength suitable for supporting the container contents.
  • the lower bottom 104 may be generally plate -like.
  • the bottom 104 may be made from metal or plastic, composite materials, or other metal materials. Other materials are also contemplated by this disclosure and are not meant to be limiting.

Other liner types and shapes may also be provided.
  • the liner 108 may be made from any suitable material. Where the contents are liquids, a liquid impermeable material may be used such as a plastic, polyethylene, or other substantially liquid impermeable material.
