Henkel has been granted a patent for a container design that includes a tamper-evident feature. The container body has a projection, and the cap has a cover member, an inner member, and an outer member. The inner member is threadably engaged to the container body and can move between two positions. The outer member includes a tamper-evident member with an abutment that engages with the projection to limit cap movement. The tamper-evident member can be permanently deformed to disengage the projection and allow cap movement.

A recently granted patent (Publication Number: US11772860B2) describes a container with a unique cap design that includes a tamper-evident feature. The container consists of a container body with a neck that defines an opening to an inner cavity. The neck includes a projection that projects radially away from the axis. The cap, on the other hand, comprises a cover member, an inner member, and an outer member.

The inner member, referred to as an inner skirt, is threadably engaged to the neck of the container body and can move between a first threaded position and a second threaded position. The cover member covers the opening in both positions and has a top side that extends across the opening. The outer member, known as an outer skirt, depends from the cover member and extends about the inner member and the axis. It includes a tamper-evident member, which is a tear-away tab that is removably connected to the outer member.

The tear-away tab has an abutment member that engages with the projection on the neck of the container body, limiting the movement of the cap from the first threaded position to the second threaded position. However, the tear-away tab can be selectively torn from the outer member, disengaging the abutment member from the projection and allowing the cap to move to the second threaded position. The tamper-evident member is spaced apart from the top side of the cover member, creating an opening between the top side and the tear-away tab for gripping the tear-away tab.

The patent also describes a method of manufacturing the cap, which involves forming the cover member, the inner member, and the outer member as a unitary structure. The tear-away tab is removably connected to the outer member by an elongate connection that extends along the axis. This connection allows the tear-away tab to tear away from the outer member in the longitudinal direction.

Overall, this patented container and cap design provide a tamper-evident feature that ensures the integrity of the container's contents. The tear-away tab and abutment member mechanism prevent unauthorized access to the container by limiting the movement of the cap. The manufacturing method described in the patent allows for efficient production of the cap with the tamper-evident feature.
