The step portion or the rib portion is provided with a recess that is concave toward an inner side of the container.

A capsule integrated with a nail polish applying element for usage by a nail polish application apparatus comprising a capsule compartment and a pressure applying element, the capsule comprising a container defining a reservoir containing nail polish fluid, the container comprising an upper face with an opening sealed with a sliding gasket and a bottom face, wherein a volume of the reservoir is reduced and an internal pressure is built in the reservoir when pressure application slides the sliding gasket towards the bottom face, and a container housing comprising a body portion shaped to receive and accommodate the container, one or more conveying tunnels having a proximal end mechanically fixated to a bottom side of the body portion and a nail polish applying element mounted to receive the nail polish fluid from a distal end of the conveying tunnel(s) for applying the nail polish fluid on a nail surface.

The invention is an integrally blow-moulded bag-in-container and preform and a method for making it. The bag-in-container has an inner layer forming the bag and an outer layer forming the container, and a mouth fluidly connecting the volume defined by the bag to the atmosphere. The container further has at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the at least one vent runs parallel to the interface between inner and outer layers and opens to the atmosphere at a location adjacent to, and oriented coaxially with the bag-in-container's mouth. Processes for manufacturing a preform and a bag-in-container as defined above are defined too.

A preform, a synthetic resin container, and a method for manufacturing a synthetic resin container in which an air passage leading from an ambient air introduction hole to a trunk can be easily preserved. In the mouth, the inner body includes a large-diameter portion provided at an upper end thereof, and a small-diameter portion continuously extending below the large-diameter portion via a connecting portion. In the mouth, the outer body is provided with an ambient air introduction hole passing through the outer body, and a neck ring positioned within a height range of the small-diameter portion. The inner body is made of a crystalline resin, and a crystallized region is formed in part of the inner body, the crystallized region having a higher degree of crystallization than other regions.

A delamination container includes a neck portion having an opening communicating with an inside of the inner layer, a shoulder portion continuously extending in the radial direction from the neck portion, a body portion having a bottomed cylindrical shape, and a constricted portion interconnecting the shoulder portion and the body portion. The diameter of the outer peripheral edge of the shoulder portion is 40 mm or more and 55 mm or less, the axial length from the outer peripheral edge of the shoulder portion to a constricted bottom portion which has the smallest diameter in the constricted portion is 12 mm or more and 25 mm or less, and a ratio of the diameter of the constricted bottom portion to the diameter of the outer peripheral edge of the shoulder portion is 0.80 or more and 0.93 or less.

The invention is drawn to a container comprising a bottom wall and at least one sidewall extending upwardly from the bottom wall. The sidewall terminates in an edge and has an inner and an outer surface. The bottom wall and the at least one sidewall form a container interior. A flexible bag having an open end is disposed within the interior of the container and over the top edge of the container. A slide ring extends at least partially circumferentially about the outer surface of the sidewall and is affixed to the open end of the bag and frictionally engaged with the outer surface of the sidewall.

A delaminatable container is provided that includes a valve member allowing suppression of interference with the motion of a mobile part during use. The present invention provides a delaminatable container including an outer shell and an inner bag, the inner bag to be shrunk with a decrease in contents, wherein the outer shell includes a fresh air inlet communicating an external space with an intermediate space between the outer shell and the inner bag, the fresh air inlet has a valve member mounted thereto to regulate air communication between the intermediate space and the external space, the valve member includes a tube having a cavity provided to communicate the external space with the intermediate space and a mobile part movably stored in the cavity.

A packaging for storing and dispensing fluid contents comprises a body defining a reservoir, wherein the body comprises a base with an aperture defined therein, a receptacle configured to store the fluid contents therein is received within the reservoir of the body, and a one-way valve positioned in the aperture. The packaging further comprises an actuator comprising a channel and an opening configured to dispense the fluid contents out of the packaging. An intermediate connecting member comprising a first connection portion configured to engage the actuator, a bellow, a second connection portion configured to engage the body, and a duckbill valve integrally formed thereon extends between the body and the actuator. The duckbill valve is aligned with the channel, and the fluid contents of the receptacle flow out of the duckbill valve, through the channel, and out of the opening upon a user applying an input to the actuator.

The container for easily dispensing contents with an open top end, a closed bottom surface, and sloped side walls. The closed bottom surface being substantially spherical in shape and connected to the side walls by a flexible hinge. When pressure or force is applied to the bottom surface's spherical shape, that bottom surface flexes or bends from a first stable convex position to a second stable concave position. The transition from the convex to concave position can dislodge contents within the container for consumption without the need of a spoon or other devices.

The invention is an integrally blow-moulded bag-in-container obtainable by blow-moulding an injection moulded multi-layer preform. The bag-in-container includes an inner layer forming the bag and an outer layer forming the container, and a single opening, the mouth, fluidly connecting the volume defined by the bag to the atmosphere. The container further includes at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the bag is anchored to the outer layer at at least one point remote from the single opening and interface vent. The invention also relates to a process and a mould for the production of the blow-moulded bag-in-container.
