Embodiment Construction

[0029] The neck 6 has a top edge 8 and a retaining flange 10 adjacent the shoulder. Between this top lip 8 and flange 10 is a bottle thread 12 . The bottle is typically blow molded from PET. The cover is typically injection molded.

[0030] The nut 14 has a skirt 16 with a ground cylindrical surface 18 (see FIG. 2 ). The inner surface of the skirt has an internal helical thread 20 which cooperates with the thread on the neck of the bottle. The upper part of the skirt has a shoulder 22 which covers the top rim of the bottle.

[0031] The skirt 16 is connected to a tamper-evident strap 24 by frangible bridges 26 (see FIG. 3). The strap covers the retaining flange 10, and when the bottle cap is released, the bridge breaks and the tamper-evident strap remains in its place. The screw cap is integral with the nozzle 28 .

[0032] The lower rounded edge of the nozzle protrudes into the top rim of the bottle for the application of an optional sealing foil 30 to protect the bottl...

Abstract

A moulded closure for a blow moulded bottle of the type in which drinks, sauces and shampoos are sold has two parts. The screw cap (14) has an integral nozzle and a tamper proof band (24) connecting it to the bottle neck. The nozzle is covered by a cover (36) hinged to a ring (38) which is captive to the screw cap. The ring is free to rotate beneath a projecting bead (32) on the screw cap and the hinge (46, 48) flexes to allow arcuate displacement of the cover to one side of the nozzle and an integral tongue (46 )allows the user to park the cover at 120 DEG to the nozzle. Tongue (46) arrests the cover at 160 DEG to the nozzle when the user tilts the cover further open and tongue (46) snaps over the bead (32). The cover (36) is attached to the ring (38) initially by frangible bridges (42) so that the ring acts as a second tamper proof band.

Description

technical field [0001] The present invention relates to a tamper-evident display cap for dispensing liquid and gel bottles, squeeze packs and similar molded containers. Background technique [0002] Retail stores such as supermarkets must make the products on the shelves accessible to the shopping public. Shoppers often need to experiment with liquid products to try their taste or other characteristics. In this case, the next shopper who buys the unit bears the loss. A serious possibility is that one person added a harmful substance to the bottle, and another person subsequently bought and used it. In order to prevent this danger, bottles and molded small containers are usually closed with caps which are capable of indicating tamper-free opening. To this end, the shape of some bottle necks is simply protected by molded tamper-evident lids, and some bottles and containers, such as beverage containers or liquid cleanser dispensers, have push / pull release valves, which prese...
