Provided is a can body containing contents such as carbonated beverages, the can body being capable of suppressing the occurrence of an unexpected opening while increasing the internal pressure resistance. In the can body, formula (A+B).Math.E/Z<1.88 is satisfied when 0<L<Y2, with the following definitions: L=D.Math.cos (12), A=X.Math.(L+Y1Y2)/Y1, and B=L+Y1Y2, under a condition of E<Z.

A container includes a container body and a lid, which has an outer lid wall portion surrounding a central portion. The outer lid wall portion provides a lid-side sealing surface, which engage with body-side sealing surface, when the lid is applied to the container body to close the container. The container further includes a securing ring inserted within the outer lid wall portion. The securing ring having a lower portion and an upper flange portion extending from the lower portion at an acute angle () of less than 80 from vertical.

The present disclosure is directed to an apparatus, system, or method for covering and utilizing a plunger. The plunger can be inserted into a cover configured or sized to receive the plunger. The cover is attached to a handle with a closure mechanism. The closure mechanism is used to close the open end of the cover after removal of the plunger from the cover. A toilet or other drain or pipe system may be unclogged using the covered plunger. When the plunger and the cover are removed from a toilet, and the plunger is removed from the cover, the cover reverses or inverts. When reversed or inverted, the cover contains water or waste material from the toilet within the cover.

A cap comprising a cap body including a top plate portion which is disk-shaped, and a skirt portion which is cylindrical and provided at a peripheral edge portion of the top plate portion, the top plate portion including a substrate and a resin coating film provided on a cap inner surface side of the substrate, the resin coating film including a polyester-based resin and a lubricant, and a sealing member provided in the cap body separately from the cap body so as to face the top plate portion, and having an outer diameter smaller than an inner diameter of the skirt portion.

A vibrating cap that works in conjunction with a container that contains a viscous substance selected from the group consisting of pain relievers, muscle relaxants and medicine. A user can remove the upper vibrating cap from the lower body portion of the container, apply the contents of the container to a desired portion of the user's body, then place the cap onto the lower body portion of the container and turn the rotating cap portion on to vibrate. The user can then place the vibrating cap over the location where the viscous substance was applied for beneficial effects.

A capping structure includes a tubular shell and a cap window. The cap window is transparent and engages with an inner sidewall of the tubular shell. The cap window includes a cover and a brace. The cover is disposed at an opening of the tubular shell, and the brace protrudes from the cover and has at least a surface being parallel to the inner sidewall of the tubular shell. A container that includes the capping structure is also provided.

A retainer for a bottle cap. In one implementation, the retainer includes a first connector at a first end, the first connector being made of a first elastic material. The first connector defines a first opening having an inner perimeter sized to be captured in a groove in a particular bottle in a slip fit. The retainer also includes a second connector at a second end, the second connector being made of a second elastic material. The second connector defines a second opening having an inner perimeter sized to receive an outer perimeter of a cap of the particular bottle in an interference fit. The retainer further includes a flexible elongate strap joining the first and second connectors.
