Abstract
A child proof and tamper evident container (C) includes a pail (10) and a screw top cover (12) screwed onto the top of the pail to enclose contents of the pail. A latching mechanism (18) is formed on the pail. A plurality of tamper evident tabs (26) and second a child proof tab (14) are formed on the cover. Both types of tabs means engage the latching mechanism as the cover is screwed onto the pail. The one tab provides an indication as to whether or not the contents of the container have been tampered with, and the second tab prevents a child from removing the cover and opening the container.
Claims10
A child proof and tamper evident container comprising:
- a pail having a threaded opening at its upper end;
- a screw top cover correspondingly threaded for the cover to be screwed onto the top of the pail to enclose contents of the pail;
- latching means formed on the pail for engaging the cover to the pail;
- a first tab means including at least three tabs integrally formed with the cover for providing an indication as to whether or not the contents of the container have been tampered with, the first tab means engaging the latch means when the cover is on the pail and the first tab means being detached from the cover before a first use, or after sale of the container;
- a second tab means also including at least one tab integrally formed with the cover for preventing a child from removing the cover and opening the container, the second tab means remaining attached to the cover throughout use of the container, and the second tab means also engaging the latch means when the cover is on the pail, a child not being sufficiently strong to disengage the second tab from the latch means whereby the child is prevented from opening the container, and the tabs comprising the respective first and second tab means all being and equidistantly spaced about the cover;
- the latching means including a plurality of locking tabs one for engaging each of the first and second tabs, the locking tabs being formed around a rim of the pail with the same spacing as that of the tabs comprising the first and second tab means;
- and,
- each tab comprising the first and second tab means having a flange extending outwardly from the base of the respective tab for a leading edge of the flange to contact one of the locking tabs so to force the respective tab inwardly as the cover is turned past the locking tab.

- a screw top cover correspondingly threaded for the cover to be screwed onto the top of the pail to enclose contents of the pail;
- latching means formed on the pail for engaging the cover with the pail;
- first and second tab means formed on the cover and engaging the latching means as the cover is screwed onto the pail, the first tab means providing an indication as to whether or not the contents of the container have been tampered with, and the second tab means preventing a child from removing the cover and opening the container, the first and second tab means each including at least one tab integrally formed with the cover;
- the latching means including a plurality of locking tabs one for engaging the first and second tab means, the locking tabs being formed around a rim of the pail with the same spacing as that of the tabs comprising the first and second tab means, and each locking tab have a triangular shape when viewed in plan with an angled leading edge and a straight trailing edge;
- the tabs of the first and second tab means each having a flange extending outwardly from the base thereof for a leading edge of the flange to contact one of the locking tabs so to force the tab of the first or second tab means inwardly as the cover is turned past the locking tab, each tab of the first and second tab means having a recess extending across the top thereof and forming a line of weakness which acts as a flex point for the tab by which the respective tab flexes inwardly when the flange contacts the locking tab;
- and,
- each tab of the first and second tab means further having a recess formed in the flange so when the leading edge of the flange passes one of said locking tabs, the respective tab of the first or second tab means flexes outwardly for the locking tab to be captured in the recess, removal of the cover now requiring the cover to be turned in the opposite direction while simultaneously pressing each tab of the first and second tab means inwardly so its associated locking tab clears the recess formed in the flange.
