Description

1 GB 2 189 475 A SPECIFICATION dispensing orifice to an open position in

which the contents of the container may be dispensed through Dispensing closure the dispensing orifice, the dispensing closure also comprising axially extending rib means projecting This invention relates to a dispensing closure, and 70 inwardlyfrom the skirt at a fixed orientation relative more particularly, to a closure having a base cap to the hinge and positioned so as to contactthe stop containing a dispensing orifice and means for of the container when the closure is attached to the attaching the base cap to a container, and a lid container, thereby establishing in use a fixed hinged to the cap for closing the orifice. orientation of the dispensing closure with respectto Dispensing closures are made with a variety of 75 the container.

means for attaching the base cap of the closure to a The invention may provide means for obtaining a container. Typicallythe closure has a base cap fixed orientation of the closure on a container provided with a flattop containing the dispensing independent of thefastening means used to attach orifice and a depending skirtwhich contains means the closuretothe container, and independentof the which co-operate with the containerto attach the 80 means used for providing a seal between the base base cap to it. A common fastening means uses cap and the container.

mating threads on the inside of the skirt of the cap The invention provides a dispensing closure which and the outside of the neck of the container. Other has means for alignment of the closure with respect means can involve a f lange on the neck of the to the container and this preferably achieves an container and a bead on the skirt which snap over 85 alignment of the hinge between the closure lid and each otherwhen the cap is pushed onto the cap with the f ront or labelled portion of the container. Another fastening device involves the use container. The dispensing orifice is thus also aligned of an intermediate sealing gasketwhich is located with the container labelling. The packaged product and coacts between the inside of the top of the cap maythus be arranged with the container labels and the top lip of the container. In this latter case, the 90 facing in one direction with the closure caps also so sealing gasket can effect a permanent connection aligned to present an aesthetically pleasing display.

between the cap and container by a heatfusing The lid and base cap may be molded as a single technique or bythe use of adhesives on both sides of piecewith a live hingejoining the lid to the base cap, the gasket material. orthe lid and base cap may be molded separately In all of the aforementioned fastening means,the 95 with a hingeforjoining thetwo.

closure becomes affixed to the container at a random In the preferred embodiment of the invention orientation. A specific point on the closure, such as employing a two- piece closure, the hinge is formed the hinge location, may have any random position by a pair of posts projecting f rom the lid, orthe base relative to a fixed point on the container. Normally cap, which engage complementary slots in the other this is not objectionable, butthere are instances in 100 of the base cap or lid, as more particularly described which it is desirable to align the hinge, orthe in United States Patent Application Serial No. 825464 dispensing orifice,with thefrontof a containerfor filed February3,which in a continuation two-partof ease in pourdispensing orfor aesthetic alignment Serial No. 664553filed October25th 1984, entitled with a label on thefront of a container.

orientation occurs when the cap is threaded onto the 105 Adesired fixed orientation of the closure hinge container bycapping machinerywhich stops when and hencethe lid opening with respeetto the thethread resistance reaches a specific point or in container can be achieved conveniently bythe conventional capping machinery which pushes the present invention. The dispensing orifice may be closure bead over a containerflange. Since the centrally located on the base cap top. More often,the containers and closures are often made by different 110 dispensing orifice is offset towards one side in manufacturers, and it is costlyto maintain tolerances alignmentwith the center line of the hinge. The rib on thread positioning, a previously unrealised meansthus also alignsthe dispensing orificewith practical solution for assuring a fixed orientation the container.

The seal functionsto prevent leakage closure having meansfor obtaining a fixed of the productthat is contained in the containerfrom orientation of the closure relativeto a containerto between the closure and the container, independent which the closure is to be attached. of normal dispensing through the dispensing orifice According to the invention we provide a 120 on the base cap. This sealing means can takethe dispensing closure for use with a containerwhich form of an internal shoulder or an annularflange has a neck provided with an axial stop and meansfor which extends downwardlyfrom thetop of the cap attachment of the containerto the closure,the with a diameterto achieve an interference sealing fit closure comprising a base cap having a topwhich with the outside diameter of the neckof the has a dispensing orifice and from which depends a 125 container. A plug seal may also be utilised which cylindrical skirt having means for attachmentto the includes an annular flange extending downwards container complementaryto the means for from the top of the cap for engagement with the attachment provided on the container, a lid joined by inside diameter of the neck of the container. Another a hinge to the base cap to enable the lid to be swung type of seal involves an annuiarf lange extending from a closed position in which it covers the 130 downwardly from the top of the cap to form an 2 GB 2 189 475 A 2 annular sealing ring for contact with the container rib passes overthe cam surface on one of the lugs, lip.
