Abstract: A tamper-evident product and related methods of production. A container includes a neck, and a tamper-evidencing component separate from the container and carried by the neck of the container in direct contact with a corresponding portion of the container neck. The component is composed of material that has higher thermal conductivity than that of a material of the container so as to concentrate heat in the corresponding portion of the container neck. The neck is thermally responsive to application of heat pursuant to tampering with the product by at least one of the following responses: an irreversible change in visual appearance of the corresponding portion of the container neck, or fracture of the container neck at the corresponding portion of the container neck.

Abstract: The current invention relates to a dispenser comprising a container (A) for holding a product to be dispensed and a dispensing mechanism (B), said dispenser comprises i. a container body (Q) having a bottom (E), and a means for interconnecting said bottom with a side opposite thereto; said container body further including at least one outlet opening (F) arranged in or near the side opposite to said bottom, preferably in or near the upper half of the means interconnecting the bottom with the side opposite to said bottom, ii. a conduct (G) connecting said container body, extending from the outlet opening (F), with said dispensing mechanism, iii. a trigger sprayer (H) and, iv. a neck (K) connecting said trigger sprayer (H) with said conduct (G) wherein said neck (K) and said conduct (G) are linked to said container body (Q) so that said neck (K) and said conduct (G) form a swan-neck or a U-shape extending from said outlet opening (F) so as to exchange air pressure and product to be dispensed.

Abstract: A tamper indicating bridged fitment is provided having an annular flange and an upwardly extending cylindrical side wall. Said fitment has a tamper indicating feature which is comprised of a bridge connected to the top edge of said upwardly extending cylindrical side wall by frangible webs. The tamper indicating bridge additionally has a slot formed longitudinally therethrough, said slot receiving a tab extending upward from a plug. The plug is a separate element which is comprised of a tab and a top wall and additionally has a downwardly extending cylindrical seal wall which acts to seal the fitment. Once the tab is inserted through the slot in the tamper indicating bridge, the fitment may only be opened by breaking the frangible tamper indicating webs connecting the bridge to the fitment side wall. Once the webs are broken, the plug may be removed by the tab and the bridge is thereby disconnected from the fitment.

Abstract: A permeation resistant closure for a mutlilayer fuel tank. A barrier layer within a closure plug aligns with the barrier layer of a fuel tank wall to form an integral and uninterrupted permeation resistant barrier surface.
