Abstract:
A number of covers are described which are particularly well adapted to protect against freezer burn of ice cream. One such cover can protect an exposed surface of a food material, such as ice cream, where the food material is positioned in a container having a wall with an inner surface. The cover includes a rim and a membrane connected to the rim wherein the membrane is adapted to contact the exposed surface of the food material. The cover may also include at least one tab connected to the rim. The rim of the cover may further include a ridge and a curtain, and the membrane may be connected to the curtain. The cover can be positioned in the container so that the rim is biased against the inner surface of the wall thus restricting the passage of air. The membrane may be flexible and may be composed of a flexible material such as polymers, rubbers, and silicone rubbers. As the membrane makes contact with the exposed surface of the ice cream, the rim may be pulled away from its biased position against the inner surface of the wall in order to burp air away from the exposed surface of the ice cream.
Abstract:
A lid for a beverage container. The lid has a drink opening portion that is moveable from a closed position to an open position. When in the open position the drink opening portion forms a depression in the top of the lid. The depression has a floor extending from a radially inner wall to a radially outer wall, the walls being integral with the top of the lid. When pushed into the open position, openings are formed on either side of the depression between the inner and outer walls and the top of the lid and the floor.
Abstract:
A container with a base (12) and lid (14), clearly indicates if the lid has been opened after a clerk loaded food into the base and closed the lid. The base and lid each has a respective lid tab and a base tab, with one tab forming a slot (26) and the tab other projecting through the slot, and with the base tab forming a barrier wall (80) that lies over the lid tab. One of the tabs has a weakened severable line (90, 92) that can be torn to allow the lid tab to be lifted to open the container.
Abstract:
A produce packaging container incorporates a basket body with an opening for inserting items inside the container and a pair of lids for covering the opening in the basket body. Each basket also includes latch elements for securing the lids in a closed configuration. A fastener is used as an extra level of security for sealing the container. The fastener can also be employed advantageously as a label. In some implementations the container is vented. Also, containers can include lids having lid-mounted latches to seal the container. Moreover, in some other implementations, the lids are configured in an overlapping manner with top mounted latches employed to engage the lids together in a closed configuration.
Abstract:
A food storage container 10 includes a base 12 and lid 14. The base 12 has a sealing flange 22, and the lid 14 has a sealing lip 32 which seals against the sealing flange 22 as with a suction cup. The lid 14 may include resilient deformable sections 46, 50, to aid in maintaining reduced pressure within the container. The lid 14 may include latch prongs 54 to mechanically retain the lid 14 in position. The latch prongs 54 may be designed to automatically release during heating of the food, permitting venting. The sealing lip 32 may include seal spacers 60 which permit air to enter the food storage container 10 during serving of hot food to avoid creation of reduced pressure in the container. The seal spacers 60 do not interfere with normal creation of a seal when desired.
Abstract:
A packaging box has a box with at least a pair of parallel sidewalls having an upper profile with a longitudinal recess that contains two or more fixing tabs and a cover with a cover area of the shape and size of the box and at least two cover flaps having slots to receive the tabs of the box and hold the cover to the box.
Abstract:
An inserted lid (1) for a box (2) is formed so that a contact region (5) can be pressed against the inside of the side wall of the box. In the non-inserted state, said side wall is slightly larger than the box opening (4). On insertion of the lid (1) into the box (2), the largest circumferential line of the contact region (5) must fit the inside of the side wall of the box as a result of an elastic deformation of the closure surface (3). To prevent the forces emanating on insertion from the side wall of the box from leading to irreversible deformations, the closure surface (3) has spring properties which are radial with respect to the contact region (5) and permit an elastic deformation of the contact region (5) in the radial direction. To ensure these spring properties, the closure surface (3) has a shape differing from a flat surface, in particular two concentric waves (7) formed constant distances away from the contact region (5) and/or a central vault (8). On insertion of the lid (1), this difference is slightly increased by the compression of the contact region (5), or the waves (7) and the vault (8) are slightly deformed, which leads to storing forces which press the contact region (5) against the inside of the side wall of the box. Owing to the shape imposed on the closure surface (3), it is ensured that no creases or other irreversible deformations form on insertion of the lid (1).
Abstract:
A combination of a container and a lid is provided. The container has an inner peripheral surface around an opening to the container interior. The lid is movable between (1) a closed position to cover the opening, and (2) an open position to expose the opening. The lid has (a) a peripheral wall, (b) a peripheral hinge that extends from the wall, (c) a plug seal wall that extends from the peripheral hinge, and (d) a central portion that extends from the plug seal wall. When the lid is in a closed position, the lid is displaceable from an outwardly projecting configuration wherein the plug seal wall is held in a non-sealing condition disengaged from the inner peripheral surface to an inwardly deformed configuration wherein the plug seal wall is held in a sealing condition engaged with the inner peripheral surface.
Abstract:
A lid for a container having an inner rim (12) extending around the top of side wall (16) includes a substantially flat central portion (4), a trough-shaped edge portion (14a) comprising rigid inner wall (15a) and outer wall (17a) connected by a bridge element (19a), and a sealing ring (18a) on the outer wall (17a) for sealingly engaging the inner rim (12) of the container. The central portion (4) is hingedly connected to the inner wall (15a) via hinge (5), and the bridge element (19a) is rigid and hingedly connected to both the inner wall and the outer wall at its terminal ends (38, 40), so that when a vertical force is applied to the lid from inside the container, the bridge element translates the vertical force exerted on the under side of the lid into a lateral force exerted on the outer wall of the edge portion, thus maintaining the seal between lid and container.
Abstract:
A cover for a container is provided with primary and secondary detent means, the primary detent means being mounted on a tamper-evident tear strip and being removable with the tear strip as opening of the cover is desired. Secondary detent means is provided on detent tabs which remain operatively associated with the cover. The limited engagement of the detent tabs with the retaining means of the cover results in facile removal of the cover from operative engagement with the container and the reinstallation and the corresponding and facile reinstallation of the cover upon the container.
