Definitions

• the present invention relates to container closure assemblies and more specifically to so called unit dose assemblies.
• Container closures of the type to which the present invention relates are not new per se.
• the patents listed below show generally unit dose packages of the type to which the present invention relates.
• Fig. 1 is an exploded view of a container-closure assembly incorporating the present invention
• Fig. 2 is an enlarged transverse sectional view taken on lines 2-2 of Fig. 1;
• Fig. 3 is a sectional view taken on lines 3-3 of Fig. 2;
• Fig. 4a is an enlarged transverse sectional view of the cap
• Fig. 4b is an enlarged fragmentary side elevational view of the nozzle end of the tube.
• Fig. 5 is an enlarged fragmentary side elevational view partly in section showing the cap activated to a diaphragm piercing position.
• the assembly essentially comprises a tube (10) and a cap (12) both made out of a plastic material such as polypropylene (polyethylene).
• the container (10) has a body portion (16) having a stepped neck or nozzle portion (18) connected to the body portion by a transition wall (20) of generally frusto conical configuration.
• the nozzle (18) includes a lower generally cylindrical portion (22) and a tip portion (24) of reduced cross-section connected by a frusto conical wall portion (26).
• the axial end face of the tip portion (24) is of reduced cross-section to define a diaphragm (28).
• the nozzle has been configured to reduce to a diameter approximately the same as a so called luer fitment so that the tube can fit on the end of a standard injection needle or can be inserted in various types of devices used in administering drugs intravenously.
• the cap (12) as illustrated is of generally cylindrical shape having a top wall (30) and a centrally depending piercing element (32) having a biased piercing tip (34).
• the cap and tube are provide with interengaging locking means, in the present instance, comprising a radially outwardly directed circumferentially extending rib (34) on the tube portion (18) and a circumferentially extending groove (36) on the interior sidewall (40) of the cap.
• the groove (36) is spaced downwardly a predetermined distance D from the piercing tip (34) of the piercing element (32) so that the tip is spaced above the diaphragm (26), when the rib (34) and groove (36) are interengaged in the manner shown in Fig. 2. This is the unarmed position of the assembly.
• the lower terminal edge of the sidewall (40) is beveled outwardly to engage more readily over the rib (34) when the cap is assembled to the tube.
• the outer peripheral surface of the cap is knurled as at (41) adjacent the lower edge of the sidewall or skirt portion to facilitate gripping by the user for applying and removing the cap.
• means for guiding the piercing element so that upon activation of the cap, the piercing element (32) engages the diaphragm (26).
• guides in the form of ribs (50) are provided on the interior wall of the cap adjacent the top wall (30).
• the circular trace defined by the inner edge (54) of the ribs (50) is preferably only slightly greater in diameter than the outer diameter D 2 of the tube portion (24) so that the cap is guided in a truly axial direction when pushed inwardly to activate the system.
• the ribs (50) have a beveled lower inner edge as at (56) to easily engage over the rounded edge tip portion (24).
