Definitions

  • the present invention relates to a closure assembly attaching a fluid dispensing device to a container.
  • the closure assembly is particularly adapted for attaching pump sprayers to containers so that the sprayer resists accidental rotation which could cause back-off of the closure assembly and result in leakage of the product in the container.
  • Hand actuated fluid dispensers are generally attached to hand-held containers by means of closure caps which engage threads on the neck of the container and provide an opening in the central portion of the closure for retention of the fluid dispensing mechanism, such as a reciprocating finger pump or a trigger actuated pump.
  • the reciprocating finger pump sprayer which is shown in U. S. patent 3,179,306 has a flange member on the pump body that is provided with teeth which engage teeth on the upper periphery of the neck of the container.
  • a screw cap attaches the pump to the container neck. While the engaged teeth hold the pump against rotation to permit lock-down of the pump plunger for shipping or storage, the container closure can still loosen during shipment and cause possible leakage because of backoff between the threads of the container and the neck closure.
  • Trigger pump sprayers of the type shown in U. S. patent 4,161,288 have been commercially successful since they can be utilized to dispense a wide variety of products. Further, the products to be dispensed are either in the form of a spray or a stream, depending upon rotation of the outlet nozzle cap. These trigger- type sprayers are sometimes subject to accidental rotation after the cap has been torqued down on the product rontainer. Such rotation can sometimes cause backoff between the threads of the container cap and the closure which can result in leakage of the contents of the container, particularly when the dispenser package . is in the shipping carton during transport or storage.
  • U.S. patent 4,161,288 An improvement in the closure system used in the trigger pump shown in U. S. patent 4,161,288 is disclosed in U.S. patent 4,345,611 which shows a child-resistant closure for a trigger pump which utilizes a special neck finish on the bottle having a plurality of outwardly projecting teeth which are adapted to be engaged by detents., or projections, vertically oriented .on the bottom inside surface of the skirt portion of the container closure member.
  • detents., or projections vertically oriented .on the bottom inside surface of the skirt portion of the container closure member.
  • patent 4,366,921 which provides a closure cap having an exterior, vertically reciprocal collar member which has teeth on its interior periphery that engages teeth provided on the neck of the container.
  • U. S. patent 4,144,983 Another type of child-resistant closure assembly for trigger pump dispensers is shown in U. S. patent 4,144,983.
  • This pump assembly utilizes a closure cap provided with a plurality of teeth that project downwardly from the bottom of the skirt of the cap and are adapted to engage and interlock with detents, or matching teeth, carried by a flexible tab integrally molded on the neck of the bottle.
  • closure assemblies provide desirable child-resistant features, many of them are unduly complicated and expensive to manufacture. Further many of these closure devices do not provide a simplified, inexpensive closure system whereby the dispensing device, i.e., a trigger sprayer can be securely locked down against the neck of the container thereby preventing counterclockwise rotation of the cap with resulting thread backoff that subsequently results in leakage of the contents of the container. Oftentimes during packaging and/or during shipment a trigger pump will be -inadvertently twisted in a direction counterclockwise to the right-hand thread tightening direction which can produce loosening of the container closure and subsequent leakage of the products from the container while the dispenser assembly is either in storage or in transit in its packing case.
  • the dispensing device i.e., a trigger sprayer can be securely locked down against the neck of the container thereby preventing counterclockwise rotation of the cap with resulting thread backoff that subsequently results in leakage of the contents of the container.
  • a trigger pump will be -inadvertent
  • the present invention resides broadly in a closure assembly for attaching a fluid dispensing device to a container having a neck portion with threads thereon.
