Abstract: A plastic injection moulded wide mouth container body and container cover locking and sealing mechanism which includes an annular flange and an annular angular notch groove respectively in a pre-determined configuration so as to provide a tight leak-proof seal when the container lid is fitted over, around and within the container body hoop annular fin and upon locking engagement. The present invention incorporates a multi-use plastic handle grip which may also be used as a closure opening levering tool to disengage the container lid from the container body in a safe and ergonomic manner. More significantly the invention, and when in use and upon first usage opening, does not require the removal of any portion of the container lid to comply with tamper evident requirements, nor needs other tools such as knives and metal levers to completely remove the container closure from the container body.

Abstract: A ventilated container for produce includes a bottom, sidewalls extending upwardly from the bottom, and a rim having a flattened top surface. The sidewalls include at least one ventilation opening located proximate the rim of the container thereby permitting the rim of the container to be generally flat and uninterrupted. The location of ventilation opening(s) proximate the rim of the container allows the flow of rising ethylene gas within the container to exit near the top of the container improving ventilation within the container. A plastic film can be applied over the top of the container and is adhered to the container with an adhesive to form a secure and rigid seal between the film and the container. The flattened surface of the rim improves the adherence between a film and the container to enclose and seal the container, aids the rigidity of the container, and lessens the likelihood of the edges of the rim being bent or folded when pressure is exerted to protect produce provided within the container.

Abstract: A cap is provided for a laboratory vessel. The cap includes a lid that can be rotated relative to the laboratory vessel from a closed position to an open position.

The skirt extends from the bottom surface of the body portion for a distance sufficient to cover the projecting bead of the container rim. An inwardly directed retaining ring is formed on an inside surface of the skirt for engagement with the projecting bead on the container. A vent is formed within the retaining ring to define a flow path past the retaining ring. The vent may be a spacing rib formed on the inside surface of the skirt with one or more flow channels formed within the retaining ring.

Abstract: The present invention includes an improved food enclosure designed to harness the steam produced during cooking so as to rapidly thaw and cook the food; however, the enclosure also advantageously vents the steam in order to provide a crispier, more desirable food product. A “venting” container according to one embodiment of the present invention, includes a tubular body having at least one open end and a cap for engaging the open end. The cap comprises upper and lower ends, which define an intermediate region therebetween. The tubular body and cap are at least partially sealed together by frictional forces resulting from the interference between opposing radially extending protrusions disposed on both the tubular body and the cap. These frictional forces are opposed and eventually overcome by a steam pressure generated from within the container, whereby the cap is driven from a closed to a vented position.

Abstract: A container system for microwave oven cooking comprises a main body, a lid, and a cap disposed in a recess in the lid. The cap is movable upward and downward through a limited range in the recess depending on steam pressure, and grooves, formed in a side wall of the cap, or in a side wall of the recess, allow escape of steam when the cap is moved upward as a result of steam pressure. The lid is also allowed to move upward and downward relative to the main container body in response to steam pressure, and, when the lid is moved upward, an additional path for the escape of stem is provided at the location where the rims of the lid and main body meet each other.

Abstract: This invention provides a container and closure lid particularly suitable for packaging semi-solids and liquids which are to be frozen. The closure lid fits entirely into the mouth of the container, providing no easy method of removal absent use of a pull tab which incorporates a tamper-evident frangible pin. The closure lid incorporates a generally flat sided seal skirt which mates with a U-shaped seal channel on the container inner wall surface to prevent leakage past the seal skirt and a locking ridge having a flat top which mates with a locking ledge face on the container inner wall surface adjacent the container mouth. The seal skirt snaps under and is covered by the locking ledge to provide no purchase along the lid edge. The container seal channel not only provides part of the sealing mechanism of the invention but also prevents translation of the lid toward the container bottom while the container locking ledge prevents translation of the lid toward the container mouth.

The cap further has a wall (19) integral with the inner end of the flange and integral with the end closure for connecting the inner end of the inner flange and the end closure. A flexible connection (23) is provided between the skirt and the inner flange which permits flexing of the inner flange relative to the skirt upon installation of the cap on the tube thereby to enable installation of the cap on the tube substantially without deformation of the tube.

Abstract: A reserve tank includes a tank body having an opening for pouring coolant into the tank body and a cap closing the first opening. The cap includes an overflow passage for discharging overheated coolant and vapor to the exterior of the tank body. The overflow passage has a second opening which opens in a downward direction. The overflow passage is formed in a groove shape on an inner surface of the cap. Additionally, when the cap fits onto the opening, a sloped portion is provided in the tank body to face the second opening portion. As a result, overflowing heated coolant and vapor are discharged from the second opening through the overflow passage, and are smoothly discharged along the sloped portion.
