Abstract: A container for beverage has a container body and a pressing member. The pressing member has a pair of guide grooves concavely formed to guide the user's fingers on two sides of the outer surface of the pressing member. The pressing member has a discharge hole positioned facing a nozzle from the container body so that the beverage contained in the container discharges through the nozzle and through the discharge hole when the pressing member is pressed towards the container body. The container body is ideal for containing coffee and pressurized gas to eject the coffee into a cup for enjoyment.

Abstract: The present invention provides a device for enhancing fuel efficiency, the device including: a first casing in which first and second rotating pulverizers are disposed at both ends of a first injection hole at the center of the first casing and a fuel inlet is disposed on a first side of the first casing; a connection part which is disposed on a second side of the first casing and in which a second injection hole is formed in the center of the connection part; a second casing which is disposed on a second side of the connection part and in which a fuel outlet is disposed on a second, discharge hole side of the second casing; and a fuel guide means which is disposed inside the second casing and which includes first, second, third, and fourth guide tubes and first and second rotating guide tubes.

Abstract: Disclosed is a tilting type chair. The chair includes: a seat on which a user is seated; a back support configured to support a back portion of the user seated on the seat; and a tilting section interposed between the back support and the seat to couple the seat to the back support. When the user applies a load to bend the back support backward, the tilting section moves the seat upward in proportion to the load applied by the user, and when the load applied to the back support by the user is removed, the tilting section moves the seat downward in proportion to the removed load. As a result, a more comfortable seating feeling may be provided to the user seated on the seat of the chair. In addition, the tilting may be limited as needed by the user. Thus, the chair may further improve the user's convenience.
