A stackable pizza pan is provided that includes a bottom that round in shape and flat; a sidewall integrally formed with the bottom, wherein the sidewall completely surrounds the bottom, wherein the bottom and the sidewall define an interior region having a vertical axis therethrough, and wherein the sidewall includes: a first or lower section tapered outward and away from the interior region and the vertical axis; a second or middle section extending outward from the interior region and away from the vertical axis; and a third or upper section tapered inward and toward the interior region and the vertical axis; and an elongated rim integrally formed with the sidewall, wherein the rim extends outward and away from the interior region, and wherein the rim includes: a curled section, wherein the curled section extends downward toward the bottom and then inward toward the third or upper section of the sidewall.

The Invention is a collection of snap, knob and other interfaces on basic shapes comprised of cubes, boxes and cups (cylinders) that fit together in versatile ways to empower builders with compact pieces. The basic shapes can fit into themselves a variety of different ways to make their constructions stronger, to make them store in a more compact and strong manner, or to occupy more space or hold food or liquids. The snaps, knobs and hooks, and the basic shapes of the pieces themselves, are all designed to maximize versatile utility that can be made with flexible pieces (like rubber or flexible plastic), rigid materials (like ceramics, cast iron or glass), and combinations of flexible and rigid materials. The combinations can also be made at different strengths because the hardness of the interfaces can be adjusted to have a secure fit, a loose fit, or a moderately strong fit.

A container for warming wax, including a bottom portion configured to support the wax warming container on a surface, the bottom portion including at least one spacer and at least one air channel, a sidewall portion extending upwardly from the bottom portion, the sidewall portion including at least one spacer and at least one air channel, and an upper portion extending upwardly from the sidewall portion, the upper portion including at least one spacer, at least one air channel, a rim, and at least one handle.

A tray and cover for storing tubes, such as collapsible tubes. A tray is used to store and transport tubes, the tubes being similarly orientated and arranged side by side in parallel alignment and being held in position by opposing pairs of tray sidewalls. A tray may also be used with a cover.

A lid for a beverage cup includes: (a) a radial collar configured to engage with a rim of a drinking cup mouth, having an inner radial surface and an outer radial surface; (b) an outer reservoir wall extending axially upward from the outer surface of the radial collar and enclosing a reservoir chamber above the radial collar, and including an upper rim; (c) a reservoir floor extending radially inward from an upper end of the inner surface of the radial collar and substantially closing the reservoir chamber from below the reservoir floor, the floor including a fluid path opening providing at least part of a fluid path extending upward through the reservoir chamber, the fluid path opening being positioned along a first diametrical line extending through the reservoir chamber; (d) an inner wall separating the fluid path from the reservoir chamber substantially in the shape of an upside-down funnel extending upward from the floor, having a minor diameter extending above a vertical level of the upper rim of the outer reservoir wall to form a spout; and (e) a cap connected to the upper rim of the outer wall with a first living hinge and including a first segment with a hole adapted to receive the spout.

A plastic article useful as a riser assembly for a septic tank or as part of another structure is comprised of a multiplicity of identical shape conical wall plastic risers. The risers are attached to each other at joints by tabs which engage rim segments; each end of the riser has alternating tabs and rim segments. A riser assembly wall undulates in the lengthwise direction. The risers nest within each other for shipment or storage.

The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

A container holder including a body portion having a first end, a second end, an inner surface, and an outer surface, wherein an interior region of the body portion is defined as a generally axial opening between the first end and the second end, and at least one retaining element disposed along the inner surface of the body portion, wherein a container is received within the generally axially opening of the body portion, and the at least one retaining element exerts a force against the container to retain the container within the generally axial opening. Furthermore, an associated method is also provided.

A pet waste collection system includes a first component and a second component detachably connected to each other. The first component has a first inner area to hold a roll of dog waste bags that is formed from a solid outer cylindrical wall and a solid bottom. A first flap encloses a top portion of the first inner area and has an aperture retrieving a dog waste bag. A pushbutton latch secures and releases the first flap. A hook attaches the first component to a dog leash. The second component has a second inner area for holding a filled dog waste bag and is formed from an outer cylindrical wall including a plurality of perforations and a solid bottom. A second flap encloses a top portion the second inner area. A pushbutton latch secures and releases the second flap. A hook attaches the second component to a dog leash.

A sterile packaging unit of a medical filter module including a filter module packed in a sterile primary package, wherein the primary package is a blister package including a molded part having a receiving compartment for the filter module and a cover part arranged on the molded part and hermetically sealing the receiving compartment, wherein the primary package includes a getter for binding molecular oxygen present in the receiving compartment and the filter module is mounted by form closure with respect to the molded part.
