摘要:
A cap for a hermetically sealed container includes an interior spike and a unitary security ring which is severed from the cap when an attempt is made to remove the cap from the container. The cap is rotatable in one direction to pierce through and puncture the neck of the container and allow access to the container contents. The security ring is severed from the cap when an attempt is made either to remove the cap from the container or to pierce the neck of the container with the interior spike.

A hermetically sealed container has a closure connected to the container by a frangible web and is provided with a unitary drop dispenser suitable for dropwise dispensing of a liquid contained therein. A hollow container body defines a liquid enclosure and has a dispensing nozzle that is unitary with the container body at a proximal end thereof. A hollow, campanulate chamber is situated at the distal end of the nozzle. The dispensing nozzle defines a liquid flow passageway in communication with the liquid enclosure and with the companulate chamber, and has a substantially uniform inside diameter. The hollow, campanulate chamber has a maximum inside diameter that is larger than the inside diameter of the liquid flow passageway and defines a drop dispensing aperture having an inside diameter that is smaller than the inside diameter of the liquid flow passageway. The drop dispensing aperture is defined by an annular flange that is connected to a closure cap at a frangible web. The drop dispensing aperture is exposed for dropwise dispensing of the contents of the container when the frangible web is fractured and the closure cap is removed.

A flanged closure insert is provided for the socket of a hermetically sealed thermoplastic container. The closure insert has an outwardly extending peripheral flange that facilitates sealing of the container. The thermoplastic material of the container may be welded to the flange for an enhanced seal.

A cap equipped with a dispensing nozzle is provided for use with a hermetically sealed container which includes a neck portion sealed by a pierceable membrane. A spike within the cap pierces the membrane when the cap is threaded onto the neck portion of the container so as to provide access to the contents of the container. The spike includes a passageway in fluid flow communication with a dispensing nozzle on the cap so as to allow dispensing of the contents of such container.

An improved closure insert is provided for throat region of a blow-molded container. This closure insert is provided with a scabrous perimeter and is permanently molded into the container throat region during container formation from a parison. The resulting seal resists loosening or disturbance when off-axis force or torque force is applied to the closure insert during container opening. The closure insert can be a subassembly constituted by removable parts that provide a variety of access options to the container contents.
摘要:
A blow-molded container is provided with an insert occluding its top opening. A closure structure at least partially encapsulates the insert article and includes a frangible web formed against the insert article. The container can be blow-molded in main mold halves and the closure structure, including the frangible web, can be formed by additional mold halves while the insert article is held in the container opening by an arm that is subsequently retracted or while the insert article is supported on a parison portion that defines the container body. In the latter instance a complete overcap for the insert article can be provided.
