The present invention is directed to a can lid that is child resistant, and at the same time senior friendly, and can be initially installed on a can to be removed by an adult, especially a senior adult, and be put back on the can in the same condition where a child could still not be able to easily remove it. The child resistant and senior friendly can lid provided has a replaceable can lid and a locking member, such that when a can is initially opened, it may be readily resealed. The child resistant and senior friendly can lid has tapered, smooth sides to make the lid difficult to grasp and a sealing ledge on the inside surface to grab the seam roll of the upper edge of the can. The lid sealing ledge is relieved in two areas ninety degrees apart leaving a ridge to maintain a seal when the lid is attached to a can. The can lid will be flexible enough to bend for removal by seniors but resistant to removal by children.

A container for the shipment and display of a food product includes a four-sided, collapsible, corrugated plastic sleeve that is selectively enclosed by a pair of opposing plastic trays. Each tray includes inner and outer flanges which are formed along the periphery of a planar plate in a spaced apart relationship and together define a continuous groove dimensioned to receive an open end of the sleeve. The inner flange includes a tapered interior surface which widens the groove towards its distal end to facilitate the process of aligning and inserting an open end of the sleeve therein. A series of projections, each semicircular in lateral cross-section, are formed onto the outer flange and are dimensioned to fittingly protrude through corresponding slots formed in the sleeve to retain the container in its assembled state during the process of packaging and transporting the designated product.

A container for holding granular or powdered material. The container includes a base and a lid. The base defines an interior space and an opening to the interior space. The lid is removably attached to the base and adapted to cover the opening. Latches are attached to the outside surface of the lid on opposing sides of the lid. Inwardly extending lugs on the inside surface of the latch are correspondingly positioned to contact deflectors on the outside surface of the base during attachment of the lid to the base.

The present invention relates to a container and a lid for food products, wherein the lid produces audible and tactile feedback when the container is closed with the lid. The invention further relates to a method for forming a lid for engagement with a container for food products. The container with a lid comprises a body with a neck surrounding an opening; at least one thread on the neck; at least one thread on the lid for engaging the at least one thread on the neck; and an engagement mechanism on the lid to secure the lid to the body when the lid is in a fully engaged position. Audible and tactile feedback are produced when the lid moves into the fully engaged position.

A locking mechanism for container and lid thereof may include a container and a lid, and the peripheral edge of the upper opening of the container has a first periphery edge. At least two first coupling portions, which are located at symmetric positions, and at least two second coupling portions, which are located at symmetric positions, outwardly protrude from the first periphery edge respectively. The lid comprises a second peripheral edge at the outer periphery thereof, and the inner surface of the second peripheral edge is configured to couple with and cover the first peripheral edge of the container. At least two first connecting portions respectively protrude from the second peripheral edge at symmetric positions, and at least two second connecting portions, which are located at symmetric positions, outwardly protrude from the second periphery edge respectively.

A method of forming an undercut which is engageable with an edge, on a side wall of a cover intermediate body using a cover intermediate body and a secondary processing die. In the secondary processing die, a moving inner core has, on the outer surface thereof, a concave shape corresponding to a convex shape of the inner surface of the undercut. The moving inner core is made up of a plurality of core segments which are arranged along the circumferential direction. Each core segment is vertically movable along an inclined surface of a core. When the moving inner core is moved upward, the moving inner core transforms smaller than the inner diameter of the side wall of a cover. The slide core has, on the inner surface thereof, a convex shape corresponding to the concave shape of the undercut.

A tamper resistant, push-on closure member for a container. The closure has a top cylindrical band portion, a bottom cylindrical band portion and a top cover. The top band has a plurality of continuous annular ridges extending inwardly along the circumference of its inner surface for contacting the side surface of the container. The bottom band has plurality of rigid teeth extending from a lower peripheral margin of the bottom band in an upward and inward direction for locking engagement against the lip of the container. The plurality of teeth are connected to a lower peripheral margin of the top band by a plurality of projections for providing a visual tamper evident indication. A plurality of tooth channels positioned between the lower margin of the top band and the upper margin of the bottom band for facilitating the flow of plastic resin during the production of the plurality of teeth.

A container having a pair of side walls and end walls and corner walls being provided between a respective end wall and side wall, a flange formed on one of the corner walls, said flange functioning as a hinge, a ring member formed integrally with the flange, the ring being sized to sit on top of the container.

A container includes a base, and a jacket adjoining the base and having a peripheral flange which defines an opening cross section which can be closed by a cover. The cover includes first snap-fit hooks distributed about a periphery of the cover for engagement in complementing first latching openings in the peripheral flange to thereby establish a form fit that prevents a movement away from the base and parallel to a vertical axis of the container in perpendicular relation to the base. The peripheral flange has four corner regions, each provided with a second latching opening for engagement of a second snap-fit hook of the cover. The second latching opening has at least one portion configured curved or inclined in relation to both a transverse axis and a longitudinal axis of the container, or has at least two straight portions extending at an inclination in relation to one another.

A lid for a container includes snap-fit hooks for interlocking engagement in complementing latching openings of an outwardly projecting flange of a jacket of the container, and stacking parts disposed on a lower side of the lid close to the periphery for form-fitting engagement in complementing stacking parts on an upper side of a further said lid, when the lids are stacked. The lower side of the lid and the upper side of the further lid have each a central region that forms a contact area via which compressive forces are transmissible in the presence of a contact between the contact areas of the lower side of the lid and the contact area of the upper side of the further lid.
