The present invention relates to a mouthpiece apparatus for bridging the mismatch in shape between the generally circular cross section of a tube, such as a straw, and the more oval or elliptic shape of a person's mouth. The mouthpiece has an input interface, an output interface, and a continuous passageway connecting the input interface and the output interface. The input interface forms a socket in which to seat the tube, and the output interface conforms generally to the shape of the lips of a person's mouth in a natural state. In alternate embodiments, the adapter may be formed with, or pre-mounted to, a tube or straw, or to a vessel such as a juice box.

A straw attachment assembly for drinking remotely from a water bottle includes a fluid coupling is fluidly coupled to a water bottle. A hose is fluidly coupled to the fluid coupling to receive water from the water bottle. The fluid coupling is positionable in a fed condition having the water bottle being inverted. In this way the fluid coupling and the hose are each gravity fed with respect to the water in the water bottle. A valve unit is fluidly coupled to the hose. The valve unit is operated by a user's mouth to deliver the water from the water bottle into the user's mouth when the user operates the valve unit.

An environmentally-friendly fiber straw structure includes a straw body made of an environmentally-friendly fiber material. The straw body has an inlet and an outlet at two ends thereof and a circular section having a circular cross-section between the inlet and the outlet. From the circular section to the outlet forms a first tapered section at a first inclination so that the outlet has an approximately elliptical shape. When in use, the mouth of a user sucks the outlet of the straw body for drinking a beverage, the first tapered section corresponds in shape to the mouth, thereby avoiding rotation of the straw body, reducing a gap between the mouth and the straw body.

The invention relates to a drinking device for the retronasal perception of an aroma substance. The drinking device comprises a liquid reservoir that is fillable with drinking liquid, a mouthpiece with a mouth end, a transport tube for drinking liquid with an inner cavity which provides a flow connection between the liquid reservoir and the mouth end of the mouthpiece, and an aroma container for adding an aroma substance to an air flow flowing through the aroma container. The aroma container includes at least one air outlet opening which is in flow connection either with at least one aroma inlet opening into the inner cavity of the transport tube or in flow connection with an aroma channel extending up to the mouth end of the mouthpiece. The liquid reservoir may include an attachment that is to be attached to the body or clothing of a user or to a bag to be worn on the body. The transport tube may have a length of at least 15 cm and preferably a length of at least 20 cm.

The present disclosure is directed to a drinking vessel that can include a drinking container and a drinking attachment that is coupled to the container. A straw can be positioned through an opening in the drinking attachment. The straw can include a top end that includes an opening through which a user can withdraw liquid and a bottom end. A drinking valve can be positioned along the bottom end of the straw and can include a tube that is open on the top and closed on the bottom and further includes at least one flow-through opening connecting the inside of the valve to the outside of the straw. A suction tube can include a tube wall that can be slid over the valve to couple the straw to the suction tube.

A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user's suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

A container includes a lid and a container body connected to the lid, and the lid includes a lid body. The lid body is further provided an elastic spout extending away from the lid body and a limiting seat mounted at the top of the lid body; a linking part is mounted on the elastic spout, and a locking part cooperating with the linking part is disposed on the limiting seat; the elastic spout has a folded storage state, and the linking part and the locking part are interlocked with each other in the folded storage state; the elastic spout has a release state in which the linking part is disengaged from the locking part to enable the elastic spout to be unfolded. The assembly and operation of the container is simple. It is easy to use and clean, and the service life of the container may be extended.

A lid assembly that includes at least one curved linkage coupling a button to a spout. The spout has a drinking aperture and is configured to convey a liquid to the drinking aperture. The button is configured to slide linearly between button open and button closed positions. The at least one curved linkage is configured to rotate the spout when the button slides linearly. The at least one curved linkage is configured to rotate the spout into a spout open position when the button is slid linearly into the button open position. The at least one curved linkage is configured to rotate the spout into a spout closed position when the button is slid linearly into the button closed position. The liquid is drinkable by a user from the drinking aperture when the spout is in the spout open position.

A container system having an access portal is disclosed. The container system may contain a selected material for access and withdraw through the portal. The portal may be engaged in any appropriate manner, such as with the application of a vacuum or pouring out.
