Abstract
A container having a base and a sidewall portion extending upwardly therefrom is characterized by striations in the sidewall which define removable strips of the sidewall portion. A shoulder adjacent the opening of the container improves handling of the container, prevents or restricts undesired rotation of the container, restricts or preventing the flow of gas or liquid or solid from above the shoulder means to below the shoulder or vice versa, and stabilizes the containers when, for example, a plurality of them is arranged appropriately. A method of use of such containers is disclosed, including the steps of providing a plurality of such containers and arranging them appropriately.
Claims20
A container having a base portion and a sidewall portion extending upwardly therefrom when said container is in its normally upright position, said sidewall portion including one or more primary scorelines means for selectively tearing from said sidewall portion corresponding sub-portions of said sidewall portion, said container being nestable with other like containers of the same size, further including shoulder means operatively attached to said sidewall portion and extending outwardly therefrom, to aid in handling the containers, to prevent or restrict rotation or other movement of the containers, to help prevent said container from being tipped over, and to restrict or prevent the flow of gas or liquid or solid from above said shoulder means to below said shoulder means or vice versa.
A plastic, injection-molded bucket having a bottom and a sidewall portion extending upwardly therefrom and defining an opening, in which said sidewall portion includes first striations therein dividing said portion into two or more strips, said first striations constituting selectable tear lines for removing material above such selected line from said sidewall portion, said container being nestable with other like containers of the same size, further including external ring means adjacent said opening and extending peripherally therefrom to aid in handling the containers, to prevent or restrict rotation or other movement of the containers, for contacting adjacent buckets or structures to support said bucket, and to restrict or prevent the flow of gas or liquid or solid from above said shoulder means to below said shoulder means or vice versa.
A plastic, injection-molded bucket having a bottom and a sidewall portion extending upwardly therefrom and defining an opening, said container being nestable with other like containers of the same size, in which said sidewall portion includes external ring means adjacent said opening and extending peripherally therefrom to aid in handling the containers, to prevent or restrict rotation or other movement of the containers, for contacting adjacent buckets or structures to support said bucket, and to restrict or prevent the flow of gas or liquid or solid from above said shoulder means to below said shoulder means or vice versa, in which said sidewall portion includes first striations therein dividing said portion into two or more strips, said first striations constituting selectable tear lines for removing material above such selected line from said sidewall portion.
A method of storage of materials, including the steps of:
- providing a plurality of similarly sized and shaped containers, each of said containers being nestable with other like containers of the same size and having a bottom and a sidewall portion extending upwardly therefrom and defining an opening, said sidewall portion further including first striations therein dividing said portion into two or more strips, said first striations constituting selectable tear lines for removing material above such selected line from said sidewall portion, further including external ring means adjacent said opening and extending peripherally therefrom for contacting adjacent structures;
- providing material to said containers;
- and arranging said containers so that adjacent of said external ring means abut one another, thereby aiding in handling the containers, preventing or restricting rotation or other movement of the containers, and restricting or preventing the flow of gas or liquid or solid from above said external ring means to below said external ring means or vice versa.
