A case in loaded state includes a bottom-cover-hinge component including a bottom with a wall, an upper opening, a lower opening, and a mechanism for fixing an insert; a cover including a wall and a peripheral wall; a side film hinge; the bottom, the cover and the hinge being one single component, molded in an intermediate manufacturing conformation fully opened flat at 180, followed by a relative pivoting closing movement; an insert, including walls, an opening, a mechanism for fixing a bottom, a content holding face which limits a storage space; and a content in the storage space; the insert being rigidly fixed onto the component with the mechanism for fixing, so that the insert extends and fits into the lower transversal bottom opening.

The disclosure is directed to an injection molding device comprising at least one injection mold with a first and second mold half during operation being displaceable with respect to each other in a first direction (z) between a closed position and an open position. The first and second mold halves forming in the closed position at least one cavity therebetween for receiving melted plastic material from an injection nozzle. The at least one cavity comprises first and second cavity sections which are by a constriction. Melted plastic material is injected into the first cavity section and travels from there via the constriction into the second cavity section. A first sensor arrangement is arranged in a cavity wall of the first cavity section and a second sensor arrangement is arranged in a cavity wall of the second cavity section to determine relevant parameters in relation to the constriction.

A cap for a container is formed so that the cap has a top plate and a circular sidewall. Two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connecting to one surface of the top plate forming a closed end, and another periphery of the circular sidewall at an opposite side of the closed end forms an opened end. Incision lines are in the circular sidewall. The incision lines form a ring member located at the opened end of the cap separated from a main body of the cap by a first incision line in between the opened end of the main body and the ring member. The ring member is connected to the main body by a plurality of connecting portions.

One aspect is an insert molded torsion bar hinge including a cylindrical metal torsion bar with a main bar body, a portion of which extends along a torsion bar axis, a first contoured bar end and a second contoured bar end on opposite ends of the main bar body. A first hinged element of molded plastic and with a first knuckle, is molded directly over and encompasses the first contoured bar end such that the first contoured bar end is fixed within and not rotatable relative to the first hinged element. The first knuckle is molded directly over and encompassing a portion of the main bar body. A second hinged element of molded plastic and with a second knuckle is molded directly over and encompasses the second contoured bar end such that the second contoured bar end is fixed within and not rotatable relative to the second hinged element. The second knuckle is molded directly over and encompassing a portion of the main bar body. The first and second hinged elements rotate and produce a torsional spring torque.

The present invention relates to a cap for a container. The cap comprises a main body having a top plate and a circular sidewall, wherein one periphery of the circular sidewall connects to the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end; and a ring member located at the opened end of the main body, separated from the main body by a first incision line, and connected to the main body by a plurality of connecting portions, wherein a plurality of second incision lines locate on the main body or the ring member and locate at one side of the plurality of connecting portions. The cap provided by the present invention will, while in its open and/or closed state, continue to be connected to its container.

A load bearing panel member having a first portion, a second portion, and an appearance surface portion is formed by injection molding such that the first portion includes a plurality of ribs forming a grid pattern on the first portion and another plurality of ribs extending toward the periphery of the first portion which may be non-orthogonal to each other and to the ribs forming the grid pattern. An internal channel may be formed within each of the non-orthogonal ribs by injecting a gas into the rib during the molding process forming the panel. An appearance surface portion attached to the first portion and second portion of the panel member forms an integral hinge between the first and second portions of the panel member. The panel member may be configured as a floor panel of a vehicle.

A method of manufacturing a component (124) having a main body (116) and at least one ring sleeve (118) through a molding assembly (100), the method comprising: providing a mold (102) having an inlet (115) and defining a hollow portion (H); placing at least one core to form a free-space (104, 106) within the component (124) inside the mold (102) to bifurcate the hollow portion (H) into a first cavity and a second cavity; pouring a molding material (117) inside the mold (102) through the inlet (115); allowing the molding material (117) to set inside the mold (102) around the core within the first cavity and the second cavity to form a main body (116) and at least one ring sleeve (118) of the component (124); connecting the first cavity and the second cavity and forming at least one first bond and one second bond (130, 132, 134, 136) between the main body (116) and the at least one ring sleeve (118); and removing the at least one core from at least part of the hollow portion (H) within the mold (102); characterized in that: providing the core with at least one recess allowing the molding material (117) to flow therethrough such that on withdrawing the core out of the mold (102), at least one first bond (130, 132) breaks and on withdrawing the core outside the mold (102), at least one second bond (134, 136) breaks.

A cover for covering an opening of a container for a food stuff includes a substantially flat cover body including at least one aperture and at least one substantially flat flap. The at least one flap including a linear proximal end configured to connect with the cover body and allow the at least one flap to rotate with respect to the cover body. A lower surface of the at least one flap includes a protrusion configured to close the at least one aperture when the at least one flap is at a first position in which the at least one flap is in parallel with the cover body. The cover body and the at least one flap are integrally formed by a co-injection molding. The container and cover are suitable for heating a food stuff in a microwave.

The present invention relates to a cap for a container. The cap comprises a main body having a top plate and a circular sidewall, wherein one periphery of the circular sidewall connects to the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end; and a ring member located at the opened end of the main body, separated from the main body by a first incision line, and connected to the main body by a plurality of connecting portions, wherein a plurality of second incision lines locate on the main body or the ring member and locate at one side of the plurality of connecting portions. The cap provided by the present invention will, while in its open and/or closed state, continue to be connected to its container.
