Closure assembly comprising a cap with integrated tamper-evident ring and strap

A closure assembly comprising an article and a cap, said cap including an integrated tamper-evident ring member and an integrated strap, wherein:

• the article forms a tubular neck around a product passage in said article, said neck forming a mouth at a top end of said product passage,
• the cap including the integrated tamper-evident ring member and the integrated strap is made as one piece of a plastic material and distinct from the article, which cap is secured on or is adapted to be secured on said neck of the article, the cap being adapted to be manually removed from the neck of the article by a user to open the product passage,
• wherein the cap has a closed position and an open position, wherein in the closed position the cap is positioned on the neck and thereby seals the product passage, wherein in the open position the cap is removed from the neck, thereby leaving the product passage open,
• wherein the cap comprises a top wall structure and a downward depending skirt having an interior side, exterior side, and a lower edge remote from the top wall structure,
• wherein the tamper-evident ring member is integrally formed to the lower edge of the skirt of the cap, said tamper-evident ring member comprising a base portion, which base portion is connected via one or more breakable bridges to the skirt, wherein the base portion is configured to remain connected to the article upon removal of the cap from the neck of the article by the user,
• wherein the cap comprises a pair of wing-shaped handles, said pair of wing-shaped handles extending outwardly from the skirt of the cap in mutually opposite directions and being configured to be engaged by a user for removal of the cap,
• wherein the wing-shaped handles each have, seen in a side view thereon, an outer periphery comprising a bottom side, a top side, and a tip remote from the skirt, where said bottom side and top side adjoin at the tip,
• wherein the strap is integral at a first end thereof to the base portion of the tamper-evident ring member and at a second end thereof integral to one of the wing-shaped handles, wherein the strap is adapted to remain connected to both the base portion of the tamper-evident ring member and the respective wing-shaped handle upon removal of the cap from the neck of the article by the user,
• wherein the base portion of the tamper-evident ring member comprises an annular ring member flange portion that has a top face, a bottom face, an inner face, and an outer face,
• wherein multiple hook members are integrally formed to the bottom face of the ring member flange portion, the hook members being distributed in a circumferential direction of the ring member flange portion, wherein each hook member comprises a leg having an upper end integral with the ring member flange portion and protruding downward from the ring member flange portion, wherein each hook member comprises a hook portion at a lower free end of the leg,
• wherein the article further comprises a circumferential flange structure which comprises an annular flange portion that is integrally formed to the neck and extends around the neck, which flange portion has a top face, a bottom face, and a periphery,
• wherein the annular flange portion on the neck of the article is provided with multiple hook member passages that each extend between the top face and the bottom face through said annular flange portion, each hook member passage being adapted to receive one of said hook members when the cap with the integrated tamper-evident ring member is secured on the neck, wherein the hook portion of each hook member engages underneath the bottom face of the annular flange portion on the neck of the article,
• and wherein the closure assembly is embodied such that upon a first time opening of the closure assembly by removal of the cap by a user the one or more breakable bridges break and the annular ring member flange portion is retained by means of the hook members.
