WO 97/00816 PCT/US96/10627 CONTAINER-CLOSURE
ASSEMBLY
TECHNICAL FIELD The present invention relates to container closure assemblies and more specifically to so called unit dose assemblies.
P:\WPDOCS'DYS\SPECIM\670698 25/11/98 BACKGROUND ART 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.
UNIT DOSE ASSEMBLY United States Patent No. 5,052,589 e 10 UNIT DOSE ASSEMBLY United States Patent No. 5,042,690 Even though these designs are generally suitable for the purposes intended, it has been found that on occasion, the caps tend to tilt or cock to the point where when the cap is pushed inwardly to penetrate the diaphragm, the piercing element aligns with a thick wall portion surrounding the diaphragm thus jamming the piercing operation.
According to the present invention there is provided a cap and tube assembly comprising: a tube for containing a product; a step nozzle at one end of the tube including a tip portion of reduced cross section connected to a lower portion by a wall portion; means defining a thin wall portion forming a puncturable diaphragm in the axial end of the tip portion to provide a discharge opening for dispensing the product; P:\WPDOCS\DYS\SPECIE670698 25/11/98 -3a cap engagable over the nozzle having puncturing means depending inwardly from top of the cap operable upon actuation of the cap relative to the nozzle to puncture the diaphragm; and a plurality of circumferentially spaced ribs extending axially from the top of the cap to a point below the tip of the piercing element snuggling engaging the tip portion in the unarmed position of the cap with the tip portion spaced above the diaphragm.
:o The assembly may further include interengaging means on the cap and lower portion 1 of the nozzle to normally position the cap and said unarmed position. Preferably, t 10 interengaging means comprises a circumferentially extending radially outwardly directed rib on the lower portion of the nozzle and a circumferentially extending groove on the interior side wall of the cap spaced upwardly from the lower terminal edge thereof. Preferably, the lower terminal edge of the skirt of the cap is bevelled.
15 Preferred embodiments of the invention will be hereinbefore described with reference to the accompanying drawings.
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; P:\WPDOCS\DYS\SPECIE\670698 25/11/98 -4- 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; and Fig. 5 is an enlarged fragmentary side elevational view partly in section showing the cap activated to a diaphragm piercing position.
4 4 BEST MODE FOR CARRYING OUT THE INVENTION Referring now the drawings and particularly to Figs. 1-3 thereof, there is illustrated a unit dose container-closure assembly incorporating the present invention. 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 S 15 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 The axial end face of the tip portion (24) is of reduced cross-section to define a diaphragm (28).
It is noted that 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 T or can be inserted in various types of devices used in administering drugs intravenously.
p:\WPDOCS\DYS\SPECIE\670698 25/11/98 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 when the i: 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 bevelled outwardly to engage more readily over the rib (34) when the cap is assembled to the tube. Further, the i!i 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.
o: 1l 5 In accordance with the present invention, means is provided for guiding the piercing element so that upon activation of the cap, the piercing element (32) engages the diaphragm To this end, guides in the form of ribs (50) are provided on the interior wall of the cap adjacent the top wall In the present instance, there are four circumferentially equi spaced ribs (50) which extend a distance D 1 from the top (30) beyond the piercing point (34) so that the upper tube portion (24) engages interiorly of the ribs (50) in the manner shown in Fig. 2. 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 P:\WPDOCS\DYS\SPECIE\670698 25/1198 -6have a bevelled lower inner edge as at (56) to easily engage over the rounded edge tip portion (24).
Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or comprising" will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
i: Even though a particular embodiment of the invention has been illustrated and 10 described herein, it is not intended to limit the invention and changes and modifications may be made therein within the scope of the following claims.
Claims (4)
