The present disclosure is related to jars and containers and, more particularly, to the manufacture of readily recyclable jars and containers. An exemplary jar is comprised of an aluminum base and a first aluminum inner cup provided with a first cavity defined with the aluminum base. An outer thread is provided about an exterior surface of the aluminum base, and an aluminum lid with a second aluminum inner cup is provided within a second cavity defined within the aluminum lid. An inner thread mateable with the outer thread is provided about an interior surface of the second aluminum inner cup. A method of manufacturing readily recyclable jars can comprise providing a primary metal material and optionally applying a precoating to the primary metal material. The primary metal material may be formed into a jar with mating threads and a lid with mating threads. The primary metal material may optionally be finished. A liner may optionally be inserted. The lid and jar are then assembled, and a plastic cup may optionally be installed.

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.

A moisture tight container includes a container body and a lid preferably linked to the body by a hinge. The body and lid include at least a first seal and a second seal in series to provide a moisture tight seal between the body and the lid. The first seal includes mating of thermoplastic-to-thermoplastic sealing surfaces of the body and lid respectively. The second seal includes mating of thermoplastic-to-elastomeric sealing surfaces of the body and lid, respectively, or of the lid and body, respectively.

A water-blocking and air-enterable structure includes a cup lid disposed with a direct drinking mouth assembly and a drinking nozzle assembly. The direct drinking mouth assembly includes a direct drinking mouth flap, a direct drinking mouth plug and an air inlet plug. The cup lid is provided with a spout and a first air inlet. The drinking nozzle assembly includes a drinking nozzle flap, a drinking nozzle seat, a drinking nozzle and an air inlet valve. The cup lid is provided with a second air inlet plugged by the air inlet valve, and a lower end of the drinking nozzle is connected with the air inlet valve through a plastic strip. The structure adopts two drinking-modes of using the direct drinking mouth assembly and the drinking nozzle assembly both being integral structures, the problems of loss of components, difficult assembly, and assembly dislocation can be avoided.

A lug closure includes a central top panel, an annular channel outboard of the top panel, a downwardly extending skirt outboard of the channel, the skirt terminating at an inward curl that defines a curl height, and lugs formed in the curl. Each one of the lugs includes a body that extends radially inwardly from the skirt. The body includes a leading edge that merges into a leading portion of the curl. The leading edge tapers in thickness from the curl height to a minimum lug thickness and forms a leading edge vertical taper angle from horizontal between 6 and 15 degrees. A trailing edge merges into a trailing portion of the curl and the trailing edge tapers in thickness from the curl height to the minimum lug thickness.

An elastic stretchable lid capable of absorbing moisture is revealed. The elastic stretchable lid includes a lid body and a hollow cap. The lid body made of soft and elastic materials is fit on an opening of a container while the hollow cap is arranged at a center of the lid body and provided with at least one air hole on a bottom thereof, a moisture-absorbing member mounted therein, and a moisture measurement unit arranged at the top thereof. Thereby the lid can be applied to different sizes of containers for closing openings and absorbing moisture to keep inner space of the container dry and prevent objects stored in the container from deterioration or mold growth. The reuse of containers protects the environment. Users can learn saturation degree of the moisture-absorbing member easily by the moisture measurement unit and further replace or regenerate the moisture-absorbing member.

A package for a medical device such as an intermittent catheter has a case which is closed at one end and open at the other end. A cap is connected to the case by a hinge to permit selectable movement of the cap between an open position, wherein access is provided to the open end of the case, and a closed position, wherein the cap prevents access to the open end of the case. A seal is connected to one of the cap and case. The seal is engageable with the other of the cap and case when the cap is closed to form a barrier that maintains a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap, respectively. One of the case and cap has a latch and the other has a receptacle for receiving the latch to releasably retain the cap in a closed position. The latches fit into the receptacle to prevent lateral forces from distorting the cap when the cap is closed. A locking slide may be used to lock the cap to the case.

A package assembly enables a user to adjust package assembly volume and includes a first (static or dynamic) package body and a second dynamic package body. The first package body has an upper body rim. Each dynamic package body provides a dynamic lid volume and has a rim-receiving groove, a lid wall, and at least one resilient portion. The rim-receiving groove is removably attachable to the upper body rim for defining a dynamic package assembly volume with the package body when in a closed configuration with the first package body. The resilient portion extends intermediate the lid wall and the rim-receiving groove and is resiliently actuable intermediate (a) a relaxed configuration for defining a maximum package assembly volume when in the closed configuration and (b) an actuated configuration defining a minimum package assembly volume in the closed configuration.

The tumbler bottle includes a cup having a side wall interior surface and bottom wall a convex interior surface. The cup side wall and bottom wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a first mixing chamber. The tumbler bottle further includes a lid, removably connected with the cup. The lid includes a side wall interior surface and a top wall concave interior surface. The lid side wall and top wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a second mixing chamber. The lid further includes a dispensing outlet and a closure. When coupled together the first mixing chamber and the second mixing chamber are in fluid communication and are configured to uniformly mix a liquid with one or more additives.
