A container includes a finish, a shoulder portion, a body, and a base portion. The finish defines an opening. The shoulder portion extends from the finish. The body extends from the shoulder portion and defines a chamber. The base portion extends at an end of the body opposite to the shoulder portion and is moveable from an as-blown position to an expanded position and from the expanded position to a retracted position. The base portion includes a standing ring, a pivot area, and a central area. The pivot area is disposed between the standing ring and the central area. The pivot area is configured to flex and move the central area along the longitudinal axis when the base portion moves from the as-blown position to the expanded position, and from the expanded position to a retracted position.

A packaged filtration mask comprising a filtration mask packaged in a container in a vacuum or a partial vacuum, wherein the packaged filtration mask comprises an indicator configured to indicate the presence of a vacuum or a partial vacuum in the container, or configured to indicate the lack of a vacuum or a partial vacuum in the container.

A synthetic resin bottle prevents a trunk from undergoing unsightly deformation in response to reduced pressure inside the bottle and also increases flexibility in terms of container design and secures a label attachment area sufficiently. A synthetic resin bottle includes a mouth, a trunk, and a bottom, with a reduced pressure absorbing region configured to be displaced toward the inside of the bottle in response to reduced pressure inside the bottle. The trunk includes a cylindrical-shaped straight region, which has a length of not less than 100 mm in an axis direction extending along a center axis of the trunk and in which no irregularities are provided. The straight region has a weight of not less than 11 times a weight of the reduced pressure absorbing region.

A self-contained meal assembly comprises a heating bag, a food pouch, and a heating element. In operation, a heating element is placed along a bottom portion of a heating bag, a food pouch is placed inside proximate the heating element, a predetermined amount of water or other nonflammable aqueous liquid is added, and the heating bag is resealed thereby allowing an exothermic reaction to occur within the heating bag. One or more steam vents may be formed through a heating bag allow steam to discharge from the interior of the heating bag during operation. The configuration of the steam vent(s) allows a controlled release of high temperature steam from the heating bag as it circulates within the heating bag to the steam vent(s) at a safe discharge angle relative to the sides of the heating bag.

A container defining a longitudinal axis and a transverse direction that is transverse with respect to the longitudinal axis. The container includes a finish and a sidewall portion extending from the finish. A plurality of ribs are defined by the sidewall. A base portion extends from the sidewall portion and encloses the sidewall portion to form a volume therein for retaining a commodity. The base portion has a contact surface for supporting the container. A plurality of straps extend radially along the base portion away from the longitudinal axis in the transverse direction, each one of the straps defines a strap surface that is closer to the finish than the contact surface. The plurality of ribs and the base portion are configured to place the container in a state of hydraulic charge-up when top load is applied to the container after the container is filled.

A medication system includes a blister pack. The blister pack includes a sheet containing a plurality of blisters each respectively containing at least one medication. The blister pack further includes a backing positioned on the sheet and a substrate layer having electronic circuitry thereon, the circuitry including traces terminating at one end at positions corresponding to each of the blisters. The blister pack is connected to an edge connector disposed adjacent to an edge of the sheet, the traces terminating at an other end to the edge connector. The medication system also includes a hub in electronic communication with the blister pack. The traces positioned such that each time a blister is punctured, the breakage event is communicated to the hub and recorded.

A steam release standing pouch has a structure in which the sealing portion is reliably peeled, and a content sealing standing pouch formed using the pouch. The steam release standing pouch has a first vapor passage portion. The distance between the inner edge of the tip of the vapor passage portion and the center of maximum expansion, which is the center of the portion where expansion is expected to be maximal, is shorter than either the distance between the inner edge of the first upper side portion and the center of maximum expansion or the distance between the inner edge of the first intermediate side portion and the center of maximum expansion.

The present invention relates to improved packages which include a rigid or semi-rigid tray having a single thermoplastic overwrap comprising a polymeric laminate surrounding the tray and having a front panel and an opposing back panel. The inventive packages also include a continuous seal circumscribing a recessed cavity of the tray which comprises a heat seal formed by heat sealing a portion of the front panel to the peripheral flange of the tray. Advantageously, when the tray is removed from the overwrap, a portion of the first film separates from the laminate and remains peelably sealed to the flange of the tray and thus, may serve as a lidding film for the container. Since the recessed cavity is still covered, the container may then be placed directly in a microwave or conventional oven to thaw and/or cook the food container within the package without first removing the lidding film.

A plastic container for storing a product. The container includes a base formed of a plastic material and sidewalls formed of the plastic material and extending upwardly from the base, ending in an open top adapted to be closed by a cap, and with the base defining an interior volume. The container also includes a snapping frame integrally formed in the base of the plastic material. The frame has a convex base shape before activation when the pressure in the interior volume is less than or equal to a predetermined critical pressure and has a concave base shape immediately after activation when the pressure in the interior volume is greater than the predetermined critical pressure, thereby increasing the interior volume and avoiding catastrophic failure of the container. Also disclosed are a method of using the container and a process of manufacturing the container.

A polymeric container including an upper portion defining an opening to an interior volume of the container. A base is movable to accommodate vacuum forces generated within the container, thereby decreasing the volume of the container. A substantially cylindrical sidewall extends between the upper portion and the base. A rigid, central pushup portion of the base is at an axial center of the base. A central longitudinal axis of the container extends through a center of the central pushup portion. A flexible diaphragm of the base extends outward from the central pushup portion.
