A screw packing container includes at least a semi-open lid and a container, said lid has a first section and a second section which are connected by a hinge. Even if the user opens the first section of the lid very vigorously, the innovative barb fixing technique used in the second section of the lid can surely prevent the entire lid from being opened. Moreover, this invention utilizes the innovative double support positioning technology to enable the screw packing container still has the function of maintaining a semi-open state after being used for a long time. In this way, the use efficiency of the screw packing container can be improved, and the user can take the screws or other parts in the container more conveniently and safely.

A method of providing packaged food items on display in a retail store includes preparing a plurality of food body portions of respective food items and loading each of the food items into respective cavities of a container. The container has a lid with at least one protrusion extending downward from a planar upper surface of the lid. After decorating each of the food body portions of the food items with a decoration portion on an upper surface of the food body portion, the lid is closed thereby moving a first retainer of the protrusion to overlie a first marginal portion adjacent the decoration portion of a first upper surface of a first food item and moving a second retainer of the protrusion to overlie a second marginal portion adjacent the decoration portion of a second upper surface of a second food item.

A lid for secure engagement with a disposable plastic cup to prevent spilling and allow for vigorous mixing of enclosed contents. The lid includes a guidance skirt, an orientation securing layer, and a secure engagement layer. The guidance skirt provides guidance of the rim of the cup into the orientation securing layer. The orientation securing layer helps stabilize the orientation of the lid during transition into the secure engagement layer. Furthermore, the lid has good flight characteristics when tossed as a flying disk because the profile of its cross-section roughly approximates the shape of an airfoil, and multiple substantially vertical portions near the perimeter of the lid augment the moment of inertia.

A method of producing and filling a paperboard packaging container with pulverulent bulk solids includes forming a tubular container body from a paperboard sheet, the body having upper and lower body openings and a container wall extending between the upper and lower body openings and having inner and outer surfaces; closing the upper body opening with a sealing membrane attached to the inner surface; providing an upper reinforcing rim; inserting at least a lower part of the upper reinforcing rim into the tubular container body at the upper body opening; forming a weld seal between the inner surface and the inserted part of the upper reinforcing rim; presenting the body to a filling station with the bottom body opening of the container body directed upward in a vertical direction; filling pulverulent material into the body through the upwardly directed bottom body opening; and closing the bottom body opening.

A container is disclosed that has a base and a lid that is rotatable about a hinge from a closed configuration to an open configuration. The lid may be secured to the base with a latch assembly. A latch assembly may have a locked position and an unlocked position.

A container including a base and a lid that is releasably attached to the base. The lid includes a channel that extends around a perimeter of the lid. At least one inlet opening provides fluid communication between an interior of the container and the channel, and at least one outlet opening provides fluid communication between the channel and atmosphere.

A one piece oversize tab closure and process for manufacturing thereof is described. The tab trim process includes punching, cutting, pre-positioning the plastic with cylinder or mechanical rocking levers, or using heating to flex the plastic for trimming and repositioning the tab. By heating or flattening the tab or window, the size of the tab is larger relative to the size of the window of the closure.

A cup lid may comprise a main body having a cup edge at an outer periphery thereof. An upper surface of the main body has a cover comprising a concave upper surface, and a first end and a second end are respectively formed at two opposed edges of the concave upper surface at corresponding positions. A concave sip portion formed adjacent to the first end, and a plane surface is formed at a bottom portion of the sip portion. A flippable sealing member extends from the plane surface, and a sip-through opening is formed overlapped with the sealing member. A month-contact portion is formed adjacent to the first end, and a height difference formed between the month-contact portion and the sip-through opening is configured to prevent the overflow of beverage when drinking.

A container lid assembly outfits a container includes a lower lid construction and a slider element. The slider element is received in the lower lid construction and is linearly displaceable in a back and forth manner relative to the lower lid construction for opening and closing the container lid. The lower lid construction includes concave surfacing and the slider element includes convex surfacing. The slider element seats atop the lower lid construction such that the convex surfacing and concave surfacing form a spherical surface-to-surface seal and enabling slidable open-close functionality. The slider element is resiliently actuable when seated atop the lower lid construction for enhancing seated engagement therebetween. The slider element includes a step-down formation cooperable with resilient actuation thereof for further enhancing seated engagement between the slider element and the lower lid construction. The container lid further locks to the container when in an actuated lower lid configuration.

A cup lid may comprise a main body having a cup edge at an outer periphery thereof. An upper surface of the main body has a cover comprising a concave upper surface, and a first end and a second end are respectively formed at two opposed edges of the concave upper surface at corresponding positions. A concave sip portion formed adjacent to the first end, and a plane surface is formed at a bottom portion of the sip portion. A flippable sealing member extends from the plane surface, and a sip-through opening is formed overlapped with the sealing member. A month-contact portion is formed adjacent to the first end, and a height difference formed between the month-contact portion and the sip-through opening is configured to prevent the overflow of beverage when drinking.
