The stopper includes a stopper main body that is attached to an upper opening of a beverage container main body and includes a liquid through hole on the inside thereof; and a lid that is axially supported by a hinge shaft that is provided at an end of the stopper main body, and which opens and closes the liquid through hole in a rotational manner; the hinge shaft connects a hinge portion of the stopper main body, and right and left hinge portions of the lid; a storage portion is provided on at least one of the right and left hinge portions of the lid, and the hinge portion of the stopper main body; at least one end of the storage portion in the axis direction of the hinge shaft forms an opening; and a torsion spring is stored in the storage portion, and a cover member covers the opening of the storage portion.

Abstract: The object of the present invention is to provide a metal container washing apparatus which can obtain hydrogen peroxide for generating hydroxyl radicals and electrolytes using a simple configuration and a simple method and which is small and has excellent portability and storability, and the present invention provides a washing apparatus that washes a metal container of the present invention includes a negative electrode that applies a negative voltage to a metal container to which a washing solution, in which a hydrogen peroxide generating agent generating hydrogen peroxide when dissolved in water is dissolved, is added; a positive electrode that applies a positive voltage to the washing solution; and a power supply that applies a voltage between the negative electrode and the positive electrode, and the inner surface in the container is washed with hydroxyl radicals generated at the time of application of the voltage.

Abstract: A lid for a beverage container includes: a cap main body that attaches to an upper aperture part of a beverage container main body; and a liquid stopping member that is installed on the cap main body in a detachable manner, the cap main body includes a liquid through-hole that is formed by notching a part of an outer periphery of the cap main body, the liquid stopping member engages along external surfaces of liquid through-hole walls that form the liquid through-hole in addition to engaging with an engagement groove that is formed on an external surface of the cap main body, and an airflow opening is formed in a back part of the liquid stopping member.

Abstract: The plug includes: a resilient member that is provided on the valve body and serves to bias the valve body in a closing direction; a valve body cover attached to the valve body in order to prevent the resilient member from coming of a rotation member rotatably provided on the valve body cover; at least two engagement claw portions that are provided on the rotation member and serve to allow the valve body cover to be engaged with an upper portion of the valve body; and claw guiding grooves and the recessed grooves serving as steps that are provided on an upper portion of the valve body, the number of the claw guiding grooves being equal to the number of or the integral multiple of the engagement claw portions, the recessed grooves allowing the rotation member to rotate.

Abstract: Provided is a plug assembly for a beverage container, exhibiting a favorable pourability without hindering a compactness. The assembly includes: an outer plug fitted into an upper opening of a container body and having an outflow passage therein; and an inner plug fitted into an upper opening section of the outer plug. Provided on the inner circumferential surface of the outer plug is a female screw having a thread continuous in the radial direction and used to attach the inner plug. Provided on the outer circumferential surface of the inner plug is a male screw corresponding to the female screw. Flow passages are formed by vertically cutting out at least a part of the male screw, and provided on the upper regions of the flow passages are control walls linearly slanting upward and outward. A stable screwed state can be consistently maintained regardless of the locations of the flow passages.

Abstract: A drinking mouth portion pointing upward is provided on a plug body of a container main body having a sealed structure. A down-pointing beverage cylindrical member is built into the container main body and has a front edge side thereof communicated with the drinking mouth portion. Provided inside a fluid passage of the beverage cylindrical member is a valve movable in accordance with a pressure difference therein. The valve is not manually opened and closed, but reacts to a suction force in the fluid passage. An up-pointing cut-out section is provided on a lower edge of the beverage cylindrical member, thus allowing one to drink up a content fluid remaining in an inner bottom section. Therefore, a relatively small number of additional parts are needed to address the spewing of a content fluid and the occurrence of a residual liquid at the time of opening the drinking mouth portion.

Abstract: Provided is a portion container compression system capable of preventing a portion container from being misaligned, and being used without contaminating surrounding items even when misalignment occurs. A content can be pushed out by squeezing the portion container installed in a receiving portion of a system main body, and formed on the front region of the portion container is an easily unsealable portion. The portion container is formed into an asymmetric shape in the front-back direction, and the receiving portion has a misalignment-prevention portion allowing the front region of the portion container to be aligned to the receiving portion, but preventing the back region thereof from being aligned to the receiving portion. The misalignment-prevention portion prevents the ejection from a misaligned portion container. Since there cannot be achieved the effects as those when the portion container is correctly installed, a user may notice the misalignment of the portion container.

Abstract: Provided is a portion container system having improved operability and user-friendliness. The system includes a receiving portion, for stowing a container on a system main body, and a rotatable handle. The container includes a peeling induction portion. The container, stowed in the receiving portion, is allowed to be compressed by swinging a handle. The container can be squeezed with the handle using the leverage, thus improving a convenience and allowing the system to be formed compact compared to a rotary apparatus. Since the container is obliquely placed in the receiving portion, the content ejected hardly splashes. Since the receiving portion is located below the rotation center shaft of the handle, the container is pressed with the handle having the rotation center shaft located above the receiving portion, thereby causing the container to be pressed with the force pushing down the handle, thus allowing for easy application of force.

Abstract: The plug includes: a resilient member that is provided on the valve body and serves to bias the valve body in a closing direction; a valve body cover attached to the valve body in order to prevent the resilient member from coming of a rotation member rotatably provided on the valve body cover; at least two engagement claw portions that are provided on the rotation member and serve to allow the valve body cover to be engaged with an upper portion of the valve body; and claw guiding grooves and the recessed grooves serving as steps that are provided on an upper portion of the valve body, the number of the claw guiding grooves being equal to the number of or the integral multiple of the engagement claw portions, the recessed grooves allowing the rotation member to rotate.

Abstract: A plug includes: a fluid passage in a main body; a valve body biased to close an inlet of the fluid passage; a cover disposed on an upper end of the main body and closing an upper opening section thereof; and a control lever of the cover that can be pushed downward to open and close the valve body. An engagement claw section is formed on an elastic section of the main body. Provided on the cover is a transverse-plate upper surface for engaging the engagement claw section. A protrusion section of the control lever abuts against and shifts the elastic section in a disengagement direction when pushing the control lever downward. The protrusion section can thus disengage the engagement claw section from the transverse-plate upper surface. The control lever biased upward by the valve body allows the cover to be easily and lightly disassembled from the main body.
