Definitions
- An open head container has a fully removable cover secured with a Lever lock or bolt ring closure.
- Tight head drums also known as closed head, have a non-removable top.
- 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.
- FIG. 4 is a cross-sectional view of the portion of the container shown in FIG. 3 .
- 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. This can result in a lower cost than a full open head drum because the closing ring is smaller than the open head ring and does not require the material strength and weight of the full open head ring.
- the tight head drum storage container with the first opening can be easier to assemble a smaller cover or lid than a full lid for an 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.
- 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 container may be used for most any type of contents including solids or other liquids including food products, detergents, cleaning agents or other chemicals, or cooking products such as oils, spreads, condiments, and the like.
- the container may also be used with other types of contents and the uses described herein are not intended to be limiting.

Description
- This application claim priority to U.S. Provisional Patent Application No. 63/380,716 filed on Oct. 24, 2022, the disclosure of which is incorporated herein, in its entirety, by this reference.
- There are numerous different configurations of an industrial container. When determining which container is appropriate for a specific use, businesses consider the container's material, gauge or thickness of the material, size, shape, linings, closures, head style, and many more factors. Some of these factors come with a multitude of options, for head style, it is just a choice between two: open head or tight head. An open head container has a fully removable cover secured with a Lever lock or bolt ring closure. Tight head drums, also known as closed head, have a non-removable top.
- The tight head drum is known to be more secure and less expensive than an open head drum. 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 present disclosure presents a hybrid solution between a tight head drum and an open head drum. For example, the container can include a tight head form with a “lid” opening. In some examples, 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.
- In one embodiment, 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.
- In some examples, 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. In some examples, the container can include a fifty five (55) gallon drum. In some examples, the container can further include a cover configured to couple to the annular bead. In some examples, 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. In some examples, the cover can include a bung opening fitting. In some examples, the container can further include a liner disposed within the container. The liner can be removable and/or replaceable.
- In some examples, 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. In some examples, the opening can be an opening between about 3 inches and about 12 inches. In some examples, the tight head drum can further include a liner disposed within the drum, the liner can include a material resistant to hazardous materials. In some examples, the top end can further include a vent opening. In some examples, the lid can include a steel cover. In some examples, 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.
- In some examples, 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. In some examples, the closing ring can include an engagement groove for engaging the annular bead of the outer rim of the lid. In some examples, the primary opening can include a circular diameter and the drum lid can define an opening having a diameter smaller than the primary opening.
- It is to be understood that both the foregoing description and the following detailed description are for purposes of example and explanation and do not necessarily limit the present disclosure. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate subject matter of the disclosure. Together, the descriptions and the drawings serve to explain the principles of the disclosure.
-
FIG. 1 is a cross-sectional view of a container, according to some embodiments. -
FIG. 2 is a top view of the container ofFIG. 1 . -
FIG. 3 is an exploded cross-section view of a portion of a container, according to some embodiments. -
FIG. 4 is a cross-sectional view of the portion of the container shown inFIG. 3 . - In some examples, 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. In some examples, 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. This can result in a lower cost than a full open head drum because the closing ring is smaller than the open head ring and does not require the material strength and weight of the full open head ring. Further, the tight head drum storage container with the first opening can be easier to assemble a smaller cover or lid than a full lid for an 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. In some examples, 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. In some examples, 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. In some examples, 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 container may be used for most any type of contents including solids or other liquids including food products, detergents, cleaning agents or other chemicals, or cooking products such as oils, spreads, condiments, and the like. The container may also be used with other types of contents and the uses described herein are not intended to be limiting.
- Referring now to
FIG. 1 , a cross sectional view of one embodiment of acontainer 100 is shown. Thecontainer 100 may include abody 102, alower bottom 104, and anupper head 106. Thebody 102 may be configured to define the shape of thecontainer 100. In some examples, thebody 102 can be cylindrical. In other examples, any suitable shape can be used including cubic or as required for space utilization or the material within thecontainer 100. Thebody 102 may be further configured to support the contents of thecontainer 100 with respect to any outwardly or inwardly directed forces imparted on thecontainer 100 by the contents or otherwise. In some examples thebody 102 can include a standard diameter of a 55 gallon drum, or about 22.5 inches. Thelower bottom 104 can be sealed to thebody 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 thebody 102. Thelower bottom 104 may include a generally flat outer surface for resting thecontainer 100 on a surface and may have a thickness and a material strength suitable for supporting the container contents. In some embodiments, thelower bottom 104 may be generally plate-like. - In some embodiments, 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. The thickness of the material can be selected based on the type of material used, the size of the
container 100, and the type of material being placed in thecontainer 100. In some embodiments, for example, the thickness of thebody 102 and thelower bottom 104 may range from approximately 1/16 inch to approximately 1 inch, or from approximately ⅛ inch to approximately/inch, or from approximately 3/16 inch to ¼ inch. In some embodiments the volume of the container may be 55 gallons. In other examples, thecontainer 100 or drum can be larger or smaller as required by the application. As such, other volumes may be provided including volumes outside the ranges mentioned. - In some examples, the
container 100 can be a lidded drum. In some examples, thecontainer 100 can further include aliner 108 disposed therein. Theliner 108 may be configured to nest within thecontainer 100 and within thecylindrical body 102 and provide a watertight or fluid tight film to maintain the contents and prevent leakage or other escape of the contents. Theliner 108 can be a vacuum-formedliner 108 and, as such, may be sized and shaped with particular dimensions. As shown, theliner 108 may be configured for nesting within thecontainer 100 and can be disposed therein via theprimary opening 110 in theupper head 106. As such, theliner 108 can include a bottom and a wall portion similar to thecontainer 100, but slightly smaller, such that theliner 108 can be disposed within thecontainer 100 and the several portions of theliner 108 can be arranged immediately adjacent to corresponding portions of thecontainer 100. As such, when contents are placed within theliner 108 and theliner 108 is within thecontainer 100, the position of the several portions of theliner 108 can be maintained by thecontainer 100 under forces or pressures exerted by the contents on theliner 108. Accordingly, theliner 108, like thecontainer 100, may include a bottom having a circular periphery as the shape of the bottom of theliner 108 corresponds to the shape of thelower bottom 104 of thecontainer 100. - While the
liner 108 has been described as having several particular parts and elements having particularly adapted sizes and shapes, in other embodiments theliner 108 may any suitable shape, including “pillow” shaped or more bag-like, and may be placed within thecontainer 100 where the contents placed in theliner 108 may press outward on theliner 108 causing theliner 108 to conform to the shape of thecontainer 100. 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. Where the contents are solids, a more permeable material may be used, such as a cloth material, netting, mesh, other material. A more impermeable material may also be used with solid contents. In some embodiments, theliner 108 may be a plastic material. Theliner 108 may be a high-density polyethylene (HDPE) material, a low-density polyethylene (LDPE) material, a polypropylene material, a co-extruded polyethylene nylon material, a co-extruded ethylene vinyl alcohol material, a laminated material, or a foil material. As mentioned, theliner 108 may be vacuum-formed or other forming methods may be used. Still other materials may also be used. Theliner 108 can be removable and replaceable. In some examples, the liner can be resistant to hazardous materials. - The
liner 104 may be configured to be engaged by the cover to be described below. As such, the free edge of theliner 108 may be sealed or connected to the perimeter of theprimary opening 110. Connecting features can be provided and any or all of the features may be continuous around the perimeter of the open top of theliner 108 or intermittent or varying features may be provided. In some examples, theliner 108 can extend upward from thecontainer 100 and engage the underside of the cover without any particular engagement with theupper head 106 of thecontainer 100. - In some examples, the
upper head 106 can be sealed to thecylindrical 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 thecylindrical body 102. Theupper head 106 may include a generally flat outer surface. - The
container 100 can include afirst opening 110 in theupper head 106. Thefirst opening 110 can be circular and/or cylindrical, however the opening can be square, trapezoidal, or other suitable shape. In some examples, thefirst opening 110 can be located at or near a perimeter of theupper head 106. In some examples, thefirst opening 110 can include a diameter smaller than the diameter of thecylindrical body 102. In some examples, thefirst opening 110 can include a diameter of about 6 inches. However, thefirst opening 110 can be less than or greater than 6 inches. For example, thefirst opening 110 can be about ¾ inches or greater, about 1 inches or greater, about 2 inches or greater, about 3 inches or greater, about 4 inches or greater, about 5 inches or greater, about 6 inches or greater, about 7 inches or greater, about 8 inches or greater, about 9 inches or greater, about 10 inches or greater, or about 11 inches or greater.

outer rim 120 of thelid 118 can include a top and a container/liner engaging portion. The top of thelid 118 can be a generally flat, plate-like, element having a peripheral edge generally matching the shape of theprimary opening 110 and being slightly larger than the peripheral orouter rim 120 of theprimary opening 110. In the embodiment shown, theprimary opening 110 and thecover 118 can be generally circular or round. In some examples, theprimary opening 110 can be square, triangular, or trapezoidal shaped, or another suitable shape. Thelid 118 can include an engagement feature (e.g., closing ring 122) arranged along the outer edge of therim 112 for engagement with theannular bead 114. In some embodiments, theclosing ring 122 can include an engagement groove configured to engage to theouter rim 120 of thelid 118. - The lid or cover 118, including the
closing ring 122 may be made of any material. In one embodiment, thelid 118 may be an injection molded lid. As such, thelid 118 may be constructed of a plastic material or other injectable material. Other materials and processes for forming thelid 118 may also be used. In some embodiments, a portion of thelid 118 may be made of a relatively clear or semi-transparent material such that the contents and the color thereof may be viewed without removing thelid 118. - In some examples, the lid or cover 118 can include a
bung opening 124 for accessing the contents of thecontainer 100 through thecover 118. In some examples, thebung opening 124 can be between about ¾ inches and about 8 inches. In some examples, the bung opening can be about ¾ inches or greater, about 1 inches or greater, about 2 inches or greater, about 3 inches or greater, about 4 inches or greater, about 5 inches or greater, about 6 inches or greater or about 7 inches or greater. In some examples, thebung opening 124 can be in ranges from about ¾ inch to about 3 inches, about 2 inches to about 4 inches, about 4 inches to about 6 inches, about 6 inches to about 8 inches, about 8 inches to about 10 inches, or about 10 inches to about 12 inches. As shown inFIG. 2 , the bung opening includes a bung 126 to seal thebung opening 124. In some embodiments, the bung can be threadely coupled or inserted into thebung opening 124. In some examples, the bung can include a standard drum plug. -
FIG. 3 is an exploded cross-section view of a portion of thecontainer 100 as shown inFIGS. 1 and 2 . As shown, the diameter α of thefirst opening 110 can be less than 20 inches. In some examples, the diameter α of thefirst opening 110 can be less than 15 inches, less than 10 inches, or less than 8 inches. In some examples, the diameter α of the first opening can be about 6 inches. In other embodiments, the diameter α of thefirst opening 110 can be less than 6 inches. The diameter α can be 5 inches or less, 4 inches or less, or three inches or less. In some examples, the diameter α of thefirst opening 110 can be in ranges from about 2 inches to about 4 inches, about 4 inches to about 6 inches, about 6 inches to about 8 inches, about 8 inches to about 10 inches, about 10 inches to about 12 inches, about 12 inches to about 15 inches, about 15 inches to about 18 inches, or about 18 inches to about 20 inches. This opening allows theliner 108 within to be easily installed and extracted from the tight head drum orcontainer 100. Because theclosing ring 122 is smaller than an open head drum, the cost of manufacturing the container assembly is lower because the closing ring is smaller and doesn't have to be as heavy duty. Further, it is easier and more cost effective to assemble thecover 118 instead of a lid for an open head drum. - The
cover 118 allows access to within the drum to position theliner 108. Once the liner is installed, thecover 118 can be sealed to theupper head 106 and access to the container can be through thebung opening 124. Theliner 108 can be removable and replaceable. -
FIG. 4 is a cross-sectional view of the portion of the container shown inFIG. 3 .FIG. 4 shows the portions of the container assembly engaged together. As shown, thefirst opening 110 comprises a 6 inch opening. Therim 112 of thefirst opening 110 comprises anannular bead 114. Thecover 118 is configured to couple to theannular bead 114 to seal the cover to theupper head 106. In some examples, thecover 118 couples to theannular bead 114 withclosing ring 122. - As shown, the diameter β of the
bung opening 124 can be less than 4 inches. In some examples, the diameter β of thebung opening 124 can be less than 3 inches, or less than 2 inches. In some examples, the diameter β of thebung opening 124 can be about 6 inches. Thebung opening 124 can be sealed with the bung 126 or a standard 2 inch drum fitting. Further, in some examples, a faucet or other fitting can be connected to thebung opening 124. - In use, the described
container 100 may be used for several types of contents. In one embodiment, thecontainer 100 may be used to store, transport, and handle, liquids. Theliner 108 may also be fitted to thecontainer 100 or can be disposed therein. In other words, in some examples, theliner 108 can be attached to thecontainer 100 or may be placed in the container, and the assembly may allow for theliner 108 to be suspended from theprimary opening 110 or theupper head 106 of thecontainer 100. Theliner 108 may be filled with the intended contents. The cover orlid 118, including at twoinch bung opening 124, may be arranged on theupper head 106 and theliner 108 and may be fitted between theannular bead 114 and theclosing ring 122 such that the liner and slides over theannular bead 114 of therim 112. Theliner 108 and/or thelid 118 can be pressed or sealed onto theupper head 106 and theliner 108 and/or thelid 118 can adhere to theupper head 106. The material in thecontainer 100 can be accessed through thebung opening 124 by removing thebung 126. Thebung 126 is replaceable as required to access the materials within thecontainer 100. - The
container 100 described herein may be advantageous for several reasons. The tight head drum with aprimary opening 110 having a diameter smaller than thecylindrical body 102 can provide the ability to insert and remove theliner 108 while being less expensive to manufacture an open head drum assembly. Thebung opening 124 can be located in a standard location for a tight head drum and fit the standard fittings to access the contents of thecontainer 100. Several parts of thecontainer 100 may be selectively sealed and/or opened for cleaning, liner extraction, filling, or other operations and thus reduce the carbon footprint in landfills, during shipping, and during manufacturing. For example, the liner may be removed after use and collapsed and recycled. - While the present disclosure has been described with reference to various embodiments, including preferred embodiments, it will be understood that these embodiments are illustrative and that the scope of the disclosure is not limited to them. Many variations, modifications, additions, and improvements are possible. Functionality may be separated or combined in blocks differently in various embodiments of the disclosure or described with different terminology.
