Abstract: The present disclosure provides a compact portable smoke infuser apparatus having a U-shaped airway for guiding a flow of smoke between a combustion chamber inlet and an outlet for a hose attachment. The airway is built into a detachable enclosure attached to a main housing body which can be removed for ease of cleaning. When attached, the enclosure rests in line with a fan and motor assembly that generates the airflow. The efficient design allows a low power motor rate which increase the battery life of the apparatus.

Abstract: The invention provides a container system comprising a lid and a container. The container includes a neck, and the lid includes a neck-surrounding space defined by two walls of the lid. At least the neck-surrounding space is vacuum insulated, or it is filled with foam, air, or any combination thereof. The lid exhibits numerous technical merits such as improved neck insulation, better efficiency in overall heat insulation, simplicity in usage, and easy manufacturability, among others.

Abstract: The invention provides a container lid with a connected (e.g. pivotally connected) handle and methods thereof. The handle includes a handle stem, a first carrying, extension, and a second carrying extension that are converged to a central region of the handle. The lid exhibits numerous technical merits such as improved finger accommodativeness, simplicity in usage, and easy manufacturability, among others.

Abstract: An example multifunctional card holder comprises: a transparent screen that is attached to a back piece, a spring inside a card holding space between the transparent screen and the back piece, where in the spring connects to the back piece so as to hold one or more cards inside the card holding space by pushing one or more cards against the transparent screen, wherein the spring in substantially straight; the back piece; and a clip attached to the back piece outside the card holding space, wherein the clip includes a first connection opening located substantially at center of upper portion of the clip and is configured to mechanically connect the card holder to an item of a user; and wherein the clip includes a second strip shape opening located at substantially center of the clip.

Abstract: The present disclosure provides example multifunctional card holders as well as systems and methods for manufacturing the same. An example multifunctional card holder may comprise: a transparent screen that is attached to a back piece, a spring inside a card holding space between the transparent screen and the back piece, the back piece; and a clip attached to the back piece outside the card holing space. The spring is of a curvy shape with two ends connecting to the back piece so as to hold one or more cards inside the card holding space by pushing one or more cards against the transparent screen. The clip includes a clip opening configured to be mechanically connected to an item of a user. The clip may also serve as a cash clip with a clip arm holding one or more cash bills against the back piece.
