A pulp-molded paper lid for a beverage cup and a method for fabricating the same is introduced. While said pulp-molded paper lid bears an external pressure to accommodate the convex-ridge ring of the cup body therein, by preloading of an insertion force of said convex-ridge ring, a generating-elasticity device of said pulp-molded paper lid is pre-compressed to compressively deform, along inward directions respectively opposite to radial directions of said pulp-molded paper lid. By removal of said external pressure, a movable bearing wall and an outermost sidewall of said generating-elasticity device exert two reversed elastically-rebound forces by a stretched deformation occurring therebetween, for clamp-retaining two opposed sides of said convex-ridge ring. Said generating-elasticity device is released from the pre-compression to exert preloaded elastic forces along said radial directions, for strengthening the clamp-retention and avoiding the technical problems of the prior arts.

The present disclosure relates to a container assembly formed from a first shell component and a second shell component releasably locked together. The first shell component includes a first side wall, a first outer wall, a first male locking portion, and a first female locking portion. Similarly, the second shell component includes a second side wall, a second outer wall, a second male locking portion, and a second female locking portion. To form the container assembly, a user rotates the two shell components to be oriented 180-degrees with respect to one another and presses the two shell components together. Upon pressing, the first male locking portion is configured to releasably lock with the second female locking portion while the first female locking portion is configured to releasably lock with the second male locking portion to releasably hold the two shell components together.

A container has a base flange on a base, and a lid flange on a lid. When the container is in a closed position the lid flange and the base flange are in juxtaposition and one of the flange edges defines a flange support surface. A lid surface is spaced above an upper base periphery when in the closed position to define a lid volume, and the base section defines a base volume. The flange support surface extends a first distance such that when the volume of the container is loaded with a rated capacity of product and the container is placed in a standing position on a flat surface using the flange support surface and a front base corner as support elements, a center of gravity of the container generates a moment about an axis of the base corner that biases the container in the standing position.

An apparatus is described. The apparatus is a closure or a lid. The closure includes a body portion, a tab, and a flange portion. The body portion comprises a first locking feature. The tab is coupled to the body portion of the closure via a hinge. The tab includes a plurality of edges and a second locking feature. The tab has a closed position and an open position, and when in the open position, the second locking feature is coupled to the first locking feature. When the tab is in a first condition, the plurality of edges of the tab pass through the flange portion from one position to another position without interference. When the tab is in a second condition, at least one of the plurality of edges of the tab overlaps the flange portion such that the flange portion interferes with the movement of the tab through the flange portion.

A water vapor guide cover includes: a cover body, including a convex top portion and edge portion, the convex top portion configured with a first peripheral wall, the first peripheral wall configured with guiding grooves, a bottom of the first peripheral wall extended outward with a groove, the groove in combination with the edge portion, further configured with a second peripheral wall, and the second peripheral wall configured with stoppers; and a box body, including a bottom portion and a third peripheral wall configured on the bottom portion, the third peripheral wall extended outward with a platform portion, inner, outer sides of the platform portion respectively configured with first, second step portions, the edge portion in contact with the platform portion, the groove positioned above the first step portion, each stopper pressed against the second step portion, and each guiding groove positioned above an inside of the box body.

A container apparatus having at least one containment member is disclosed that may include a bottom and at least one sidewall, an interior and an open end. The container may also include a flange that extends around a free end of the at least one side wall, and a plurality of wall members (or castellations) connected to/formed with/that extend from the flange. The plurality of wall members may be separated by ventilation apertures, with the plurality of wall members and the ventilation apertures extending around the perimeter of the free end. A sealing material, such as a removable film, may extend over the open end to enclose the containment member.

The disclosure relates to forming shaped thermoplastic articles having smooth peripheries. Many thermoplastic articles have sharp edges formed upon molding or cutting the article from a feedstock sheet. Such sharp edges can damage thin plastic films or flesh which they contact, and smoothing the edges is desirable. Described herein are methods of forming a smooth periphery for such sharp-edged articles by rolling over the sharp edge. The smoothing operation is performed by forming a deflectable flange including a bend region separated from the potentially sharp peripheral edge by a spacer, deflecting a portion of the deflectable flange, and softening at least one bent portion of the deflectable flange to yield a smooth periphery upon cooling. A liner sheet may be attached to the feedstock sheet prior to, during, or after forming and can be peelable therefrom.

A container assembly including a container member having a first cavity for holding a substance therein and a second cavity formed adjacent its bottom edge portion and extending upwardly therefrom, the second cavity having a top wall portion, a lid member engageable with the container member for closing access to the first cavity, the lid member having a raised wall portion configured to be receivable within the second cavity of the container member so as to form a pedestal for the container member, and at least one bumper member associated with the top wall portion of the second cavity for abutting the raised wall portion of the lid member when the lid member is inserted into the second cavity, the at least one bumper member increasing the coefficient of friction between the lid member and the container member when the lid member is received within the second cavity.

A sports bottle is described. The bottle includes a hollow body comprising a housing having a peripheral wall, a cylindrical drink holding chamber inside the peripheral wall; a plurality of mixing chamber in fluid communication with the drink holding chamber, each one of the mixing chambers being hemispherical chambers at opposed ends of the cylindrical drink holding chamber; and an outlet for dispensing drink from the drink holding chamber, the outlet being disposed on an outside of one of the mixing chambers and in fluid communication therewith. Also described is a sports bottle including a hollow body comprising a housing having a peripheral wall, a drink holding chamber inside the peripheral wall; an outlet for dispensing drink from the drink holding chamber, the outlet being disposed on an outside of the peripheral wall and in fluid communication with the drink holding chamber, a hold for storing solid nutrition supplements, the hold comprising a plurality of supplement chambers being separated from the drink holding chamber and disposed within the peripheral wall; and a supplement chamber selector to facilitate access through the peripheral wall to a selected one or more of the supplement chambers.
