Benefits of technology

[0012] Accordingly, it is an object of the present invention to provide a crown closure that is easier to use by virtue of the fact that it requires less force or torque for removal from a container, such as a beverage container or bottle.
[0013] It is a further object of the present invention to provide a crown closure that requires less force to remove than the standard crown closure with 21 grooves.
[0014] It is a further object of the present invention to provide a crown closure that requires a torque of from about 2 in lb to about 9 in lb for removal.
[0015] It is another object of the present invention to provide a crown closure that does not harm the hand of the person or at least reduces the harm to the hand of the person removing the cap from the beverage container or bottle.

Problems solved by technology

However, neither development solves the present problem.
Further, the crown closure with 29 grooves is unsatisfactory because the loss of carbonation is unacceptable (a loss of carbonation of greater than 5%).
Therefore, the crown closure with 21 rounded grooves and the crown closure with 29 grooves do not provide the desired advantages.

Embodiment Construction

[0023] According to a preferred embodiment, the torque required to remove the crown closure with 27 grooves of the present invention is lower than that required to remove standard crown closures with 21 grooves. More specifically, the torque required to remove the crown closure of the present invention is from about 2 in lb to about 9 in lb, preferably from about less than 2 in lb to about 4 in lb. As discussed above, the torque required to remove a standard crown closure with 21 grooves is from about 8 in lb to about 13 in lb, and in some cases as high as 15 in lb.

[0024] As less torque is needed to remove the crown closure of the present invention, the result is a softer feel upon removal of the closure that benefits consumers and helps reduce the number of unsatisfied consumers.

[0025] The crown cap of the present invention is preferably provided with a plastic packing in the interior 1 that may, optionally, be PVC (polyvinyl chloride), PVC-free or another thermoformed material t...

Abstract

The present invention relates to a crown closure with 27 grooves that is opened or removed by applying a rotating force or a removal twist with a torque of from about 2 in lb to 9 in lb. The crown closure has a smaller contact surface between the grooves and the lip of the container that reduces friction and requires less force to open and therefore advantageously diminishes any potential harm the hands of those opening the closure.

Description

RELATED APPLICATIONS [0001] This application is a continuation-in-part of International Patent Application No. PCT / MX 03 / 00046 filed Jun. 4, 2003 and claims priority to Mexican Patent Application No. PA / a / 2004 / 007219 filed Jul. 27, 2004.FIELD OF THE INVENTION [0002] The present invention relates generally to an improved container closure. More particularly, the present invention relates to a crown closure that requires less force to be removed from a container, that does not harm consumers' hands during the removal process, and that prevents excessive loss of carbonation. More specifically, the present invention relates to a preferably metallic crown closure with 27 groves. BACKGROUND OF THE INVENTION [0003] In general, container closures, such as bottle caps, are typically composed of a circular piece of die stamped steel or other suitable metal that is crimped over the top lip or bead of a bottle. Typically, the cap is removed with a tool that grabs a portion of the lower edge of ...
