Abstract The tube has a peg-shaped neck extension (3) at its upper end, which contains a predetermined breaking point (4). The neck extension (3) is generally positioned under the removable protective cap (7). A short socket (9) is formed on the upper side of the cap (7) in an axial direction, the interior diameter of which is slightly greater than the diameter of the neck extension (3). The inner surface of this socket (9) and the outer surface of the neck extension (3) are provided with corresponding notch flanges (5) or notch grooves (10), such that the cap (7) and the neck extension (3) are non-positively connected to each other when rotated about the longitudinal axis, when the cap (7) with the socket (9) is positioned on the peg-shaped neck extension (3). If the cap (7) is rotated in this position about the longitudinal axis with slight pressure simultaneously exerted then the peg-shaped neck extension (3) is sheared off at the predetermined breaking point (4) and the tube is thereby opened. The cap (7) thus acts as protective cap on the one hand and as a tool for opening the tube on the other hand.
A container having a dispensing nozzle at one end thereof, a severable axially extending twist-off tab at the dispensing nozzle attached to the nozzle by a predetermined breaking point, the twist-off tab having longitudinal serrations on its outer surface, a circular flange constructed and arranged to outwardly extend from the nozzle and to enclose the tab, a removable closure cap for sealing the dispensing nozzle having an elongated top portion including an axially extending socket with a diameter slightly greater than the diameter of the tab, and serrations within the socket complementary to the serrations on the tab for interconnecting the socket and tab together when the closure cap is removed and inverted and the socket is fitted over the tab whereby exerting rotational force on the cap twists the tab away from the nozzle at the predetermined breaking point.

A container having a dispensing nozzle at one end thereof, a severable axially extending twist-off tab at the dispensing nozzle attached to the nozzle by a predetermined breaking point, the twist-off tab having longitudinal serrations on its outer surface, a circular flange constructed and arranged to outwardly extend from the nozzle and to enclose the tab, a removable closure cap for sealing the dispensing nozzle having an elongated top portion including an axially extending socket with a diameter slightly greater than the diameter of the tab, and serrations within the socket complementary to the serrations on the tab for interconnecting the socket and tab together when the closure cap is removed and inverted and the socket is fitted over the tab whereby exerting rotational force on the cap twists the tab away from the nozzle at the predetermined breaking point.
Claim 3
Dependent Claim
48 words
A container as in claim 1 wherein the top portion of the removable closure cap includes an annular recess therein constructed and arranged to accommodate the flange outwardly extending from the nozzle when the closure cap is removed and inverted and the socket is fitted over the tab.
