Benefits of technology

[0010] A cap is provided which includes a top and an axially downwardly extending skirt. The top includes a seat for sealably engaging an aperture at one end of the nozzle neck and the skirt includes internal grooves for engaging the nozzle threads along with an internal circumferential lip for sealably engaging the shoulder ring. This seal arrangement protects the threads from environmental contamination. The shoulder ring is spaced apart from the seat for enabling simultaneous sealing of the aperture and the ring upon rotation of the cap onto the nozzle.

Problems solved by technology

However, none of these devices have addressed the contamination problem with regard to the threaded engagement between the cap and the bottle or nozzle shoulder.
That is, contaminants may enter the nozzle and nozzle aperture area by contamination of the threads and migrate therepast by a operation of the screw threads during removal and replacement of the cap or closure on the bottle nozzle.

Embodiment Construction

[0015] With reference to FIGS. 1-3, there is shown a closure 10 in accordance with the present invention which generally includes a nozzle 12 disposed on a bottle 14 and having a neck 18 and a shoulder 20. The nozzle 12 may be inserted into the bottle 14 or otherwise formed therein.

[0016] The closure 10 may be formed from any suitable injection multiple polymer preferably polypropylene. The closure 10 is most suitable for small bottles having a capacity of less than about 8 ml which necessitates small closure 10. Such small closures makes removal of the cap difficult especially where the primary user may be elderly or with limited hand mobility. This is further a concern for dropper bottles where the elderly are the primary users.

[0017] As hereinafter described in greater detail, the shoulder 20 includes a circumferential ring 24 and threads 26 disposed between the ring 24 and the neck 18.

[0018] The closure 10 further includes a cap 30 having a top 32 and an axially downwardly ex...

Abstract

A closure for a dropper bottle includes a nozzle having a neck and a shoulder. The neck includes an aperture at an end thereof for dropwise dispensing of a liquid, and the shoulder includes an outstanding circumferential ring and threads disposed between the ring and the neck. A cap is provided with a top and an axially downwardly extending skirt. The top has a seat for sealably engaging the aperture, and the skirt has internal grooves for engaging the nozzle threads and an internal circumferential lip for sealably engaging the ring. The lip is spaced apart from the aperture for enabling simultaneous sealing of the aperture and the ring upon rotation of said cap onto said nozzle.

Description

[0001] The present invention generally relates to closure devices and more particularly relates to an injected molded closure for a dropper bottle which provides for simultaneous sealing of a nozzle outlet and protection of internal formations for enabling engagement and disengagement of the closure with a bottle. [0002] A great number of injection molded caps have been developed over the years for the sealing of dispensing vials and bottles during non-use thereof. [0003] Generally two types of bottle caps have been developed, namely push-on-caps and thread-on-caps. Push-on-caps are installed by aligning the cap with the opening of the bottle and simply applying an axial force to the top of the cap. [0004] As is evident, a thread-on-cap generally requires that the cap and bottle be aligned and a rotational force applied to the cap, or bottle, in order to produce a sealing engagement. [0005] Heretofore, however, such sealing engagements have been directed principally to a nozzle outl...
