An insulating container may include an opening, which can be sealed by a closure. The closure may have an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of “flip” type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap.

The invention herein provides a bottle for carrying a fluid or a semifluid, the bottle including: a mouth, a top section, a body, a bottom section, and a base each located sequentially on a y- axis; the body of the bottle comprising a plurality of planar walls, each wall having the same height and width and located perpendicular to the plane of the base on an x-axis, and a cross section of the body being a polygon selected from: triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, decagon, and dodecagon; and a closure having a cross section of a circle or a polygon, and the closure reversibly attachable to the mouth to close the bottle and removable from the mouth to open the bottle. Further, the invention describes methods to obtain purified water using a filtration and purification device.

Polymer compositions may comprise propylene, present in a range of 80 to 95 wt % of the polymer composition, and two comonomers selected from a group comprising ethylene and C4-C10 alpha olefins, wherein the polymer composition has a total content of the comonomers in the range of 5 to 20 wt % of the polymer composition. Cap liners may be formed from the polymer compositions. Caps may comprise a closure formed from polypropylene and a polypropylene-based cap liner that lines at least a portion of the closure.

A system and method for implementing cap closure for a carbonated beverage is disclosed. According to one embodiment, an apparatus includes a cap liner having a circular ring shape. The apparatus further comprises an outer lip and an inner portion of the circular ring shape. The outer lip is wider than the inner portion, and the outer lip has two or more members extending away from a center of the outer lip.

A bottle can has a curl part at an opening end of a mouth part thereof. The curl part has an upper end curved part in which an upper part of a neck shoulder part of the mouth part is curved outward and an outer wall part extending downward from the upper end curved part. A predetermined angle at which an outer edge side of a lower end face of the outer wall part opens is formed between the lower end face of the outer wall part and the neck shoulder part. An inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.

A bottle, in particular a reusable and refillable bottle for CO.sub.2-containing drinks, which can be carbonated and stored in the bottle. A bottle with better usage properties is to be achieved. The bottle includes a closable liquid container with an adapter which is attached or flanged to the base of the liquid container and which contains a CO.sub.2 tank.

A closure (750) is provided and comprises a top plate (755) and a sidewall (760) depending from the periphery of the top plate. The closure includes a sealing member (765) which depends from the top plate within the sidewall. The top plate includes a foamed region which is restricted to being within a boundary defined by the sealing member; the sealing member being substantially unfoamed.

An inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.

A bottle cap comprised of an upper cap body, a valve and a threaded insert wherein the threaded insert is configured to be secured to the opening of a bottle. Liquid is discharged through the cap during the collapse of the bottle. Bottle un-collapsing creates negative pressure, which closes the valve and creates a temporary air seal, preventing further air entry into the bottle. The valve further prevents loss of carbonation in the bottle.
