The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.

An expandable triangular pizza storage container with a set of microwaveable triangular trays for the separation, microwaving and serving of individual slices of pizza. The storage container has a series of concentric triangular compartments that are expanded from a flexible polymer, accordion-style container body. The lid also has a triangular configuration with a replaceable compressible gasket, a set of four locking wings extending from each side that frictionally engage a rigid triangular top ring of the container body, and a central vent. The trays may incorporate uniform concave pockets to facilitate crisping of the pizza crust in the microwave and be of a solid or cored design, of microwave and dishwasher friendly material.

A plastic preform includes a hollow body portion including a closed base portion and a lower portion and a lower portion extending upwardly from the closed bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening positioned at a top of the neck portion, threads positioned below the dispensing opening, a tamper-evident formation having a lower surface and positioned directly below the threads, and a support flange having an upper surface and a lower surface and positioned below the tamper-evident formation. In an embodiment, the plastic preform is formed of a material comprising polyethylene terephthalate (PET), and a vertical distance from the lower surface of the tamper-evident formation to the lower surface of the support flange is from 0.125 to 0.150 inches. Containers and methods for molding preforms and making containers are also disclosed.

Collapsible containers and a method of their manufacture are disclosed herein. The collapsible containers have one or more collapsible wall sections and a stiff upper and lower tier. The wall sections have living hinges and three or more tiers between the hinges. A thermoplastic elastomer layer may join separately made portions of the container together. The containers may be made by molding and overmolding. The containers include inter alia bulk liquid containers, jugs, tubs, baskets, bottles, and food containers. The method of manufacturing includes placing a container component and a matching container body comprising a stiff first tier, a stiff second tier, and a collapsible wall section in a mold; assembling the container body with the container component to close one end of the container body; and overmolding a thermoplastic layer around the container body and the container component.

A liquid container includes a cup having a brim forming an opening into an interior region of the cup. The container also includes a lid configured to mount on the brim of the cup to close the opening.

A packaging device and a manufacturing method thereof are provided. The packaging device includes: a bottom plate (1); a side plate (2) fixed to a surface of the bottom plate (1), the bottom plate (1) and the side plate (2) forming a containing cavity through joint enclosure; and a supporting piece (3) in the bottom plate (1). The bottom plate (1) completely wraps the supporting piece (3). An extending direction of the supporting piece (3) is roughly parallel to the surface of the bottom plate (1). A material of the supporting piece (3) is different from that of the bottom plate (1), and a strength of the supporting piece (3) is greater than that of the bottom plate (1).

A package is disclosed that includes a container and a closure. The container includes a container neck finish having a radially inner surface, a radially outer surface, and an axial outward end surface extending between the radially inner and outer surfaces. The radially outer surface includes a straight cylindrical upper portion and a threaded cylindrical lower portion. The closure includes a base wall engaging the axial outward end surface of the container neck finish, an external skirt extending away from the base wall and having a threaded section with internal threads engaging the container neck finish, and a pleated section between the threaded section and the base wall.

A sip lid for a children's drinking vessel includes a spout component having a first end region and a second end region opposite to the first end region. The spout component is shaped and sized to be received within a child's mouth. The first end region comprises one or more openings configured to allow liquid to be extracted through the spout component when the child is applying suction to the spout component. The sip lid also includes a base component extending from the second end region of the spout component and surrounding the spout component. The base component is made from an elastic material configured to allow the base component to stretch over differently sized mouths of drinking vessels to form a liquid-tight seal between the base component and the drinking vessels.

A rectangular perimeter egg carton comprising: a lid, and a base separate from the lid, wherein the lid and base are assembled together to from a closed egg carton, the base having a top wall and a rectangular array of recessed base cells arranged in rows and columns depending from the top wall, each base cell having an open top end, a sidewall and a closed bottom wall and being sized and shaped to hold one egg in a generally upright position with the long axis of the egg disposed in a vertical direction transverse to a base reference plane in which the bottom walls of the base cells reside; the base and lid having respective mating rectangular perimeter edges, including opposing front and rear side edges and opposing left and right side edges, that mate with each other in a closed position to from the rectangular perimeter egg carton for enclosing an egg in each of the respective cells; and a plurality of spaced apart venting ports formed in each of the perimeter side edges of one or more of the base and lid perimeters for releasing moisture from the closed egg carton.
