Definitions

  • a three-part closure sealing and dispensing device A three-part closure sealing and dispensing device
  • This invention relates to a multifunction closure device to seal and dispense many types of industrial substances and relates particularly to a container closure and sealing wad which can seal distorted and un-evenly formed containers through the characteristics of the closure in combination with the unique shape of the three dimensional flexible sealing wad and is adapted to engage a container to create a improved method of sealing one or more substances, and additionally can facilitate the dispensing and mixing of a material, such as a liquid, solid, powder or granular material, into the container while offering a number of tamper-proof security features for many types of industries, packaging harmful or toxic substances.
  • a material such as a liquid, solid, powder or granular material
  • This three-part closure sealing and dispensing device seals the contents in the container providing a solution for the handling, mixing and the transporting of harmful chemicals when handled or shipped as previous closure devices many times fail when toxic or dangerous chemicals are stored in them, as the closures and sealing wads consistently fail when the closures crack through pressure or the sealing wad material becomes old and deteriorates or when the container is stored in extreme climates or altitudes or when they are mishandled in storage or the transport or shipping of them.
  • This unique purpose multifunction dispensing closure has been invented to be used in the harmful goods and toxic chemical industry or the like to provide a much safer system when handling chemicals by sealing the container through a specially designed and shaped closure with a one or two-part three dimensional moulded sealing wad, which also incorporates a separate chamber dispensing closure device that keeps apart toxic or harmful chemicals until the time of use in a separate isolated chamber with an activation mechanism that can be activated automatically when the closure is undone from the container at the time of use.
  • the three-dimensional designed sealing wad system prevents dangerous chemicals from leaking when the container closure cracks when applied under load or pressure with damage occurring through dropping accidentally or through extreme temperature differences or mishandled in transport and has brought about many important security features through the introduction of a sophisticated tamper-proof evident security feature to prevent children tampering with any of the harmful or toxic chemical substances stored in the container.
  • this particular closure will still create a seal through its unique three-dimensional wedge-shaped design that forces the container back into shape and round when the closure is screwed on and tightens and prevents any possibility of leakage, making it ideal for such extruded below moulded containers used widely through the chemical industry or the like.
  • this invention has been designed and developed to overcome many of these outstanding issues and problems by creating a new universal container closure incorporating a three-dimensional sealing system which does not only rely on the narrow top spout lip surface which is only one dimension, but instead engages all three neck spout different wall surfaces to alleviate and overcome this problem.
  • the existing closures currently used in the industrial chemical industry or the like seal the container by sandwiching and compressing a one dimensional flat wad seal between the closure and the inside top rim wall only of the container under pressure, but by doing it this way it creates hairline fractures in the plastic closure that is used and eventually can crack completely allowing the dangerous goods to escape from the container closure as too much torque is required to actually compress and sandwich the air cells of the sealing wad enough between the container and the closure to achieve an adequate high pressure seal, hence causing the products to leak through the plastic closure cracking and in some instances causing the closure to fail completely when under pressure in storage through extreme temperatures or altitude differences at the time of their storage or transport.
  • This new type of closure with this unique three-dimensional flexible sealing wad proposed is formed through a process which forms the seal through heat and pressure molding which creates a three dimensional seal with a PA protective lamination coating which is far more superior through the forming process which achieves the exact shape, dimensions and tolerances when compared to the already existing one dimensional seals which are currently fabricated through cutting the shape of the seal out of a flat extruded sheet of PE foam polymer which has been laminated with a film of PA to create the one dimensional sealing wad which are still currently utilized widely in this industry and do not seal the container in a safe or satisfactory way.
  • the closure can be used through the combination with the flat flexible sealing wad on its own, which when used, prevents the closure from cracking and in turn, leaking when placed under extreme stress through its unique three-dimensional sealing capabilities created by the shape of the closure making the sealing wad conformed to a specific three-dimensional shape which is molded in the top inside rim of the closure which by in turn seals up the three different wall faces and the neck spout lip of the container.
  • the closure can be sealed through the flexible formed three dimensional wad which has been molded into a form which seals the container even if the container has not been formed to a consistent standard or has uneven internal or external neck spout wall thicknesses where the closure sealing wad seals on to, or is out of round or the dyer-meter varies extremely or if the tops sealing surface is not flat or severely deformed, or the shape has changed since the container was first molded.
  • the container can be sealed through the closure with the molded flexible formed three-dimensional wad which can be formed with a laminated aluminium induction seal film, or can be laminated with a sensitive adhesive film which is activated by pressure or heat which provides a unique security device through the tamper-proof evident security seal which can be activated and released once the closure has been unscrewed from the container.
  • the molded flexible formed three-dimensional wad which can be formed with a laminated aluminium induction seal film, or can be laminated with a sensitive adhesive film which is activated by pressure or heat which provides a unique security device through the tamper-proof evident security seal which can be activated and released once the closure has been unscrewed from the container.
  • the fourth valuable part of this closure system is that the dangerous substances can be kept completely separate in the same container safely apart until the time of use in a separate delivery device chamber through separating for example, one chemical liquid in the container and the other toxic or dangerous part of the substance in granule form or the like in the chamber separately until the closure is activated and the two or more substances are required to be mixed together at the time of use.
  • this part of the invention through this unique closure and three dimensional sealing wad and dispensing device keeps liquid, granule, powder and tablet or other types of substances sealed so they will not degrade from oxygen or moisture and protects the contents in the container through providing a number of safety features which protects the dangerous substances from accidentally mixing when the container is dropped or in storage or transported providing a completely sealed unit that is safe and secure to be stored in extreme variable temperatures and is able to be transported through any extreme climate or terrain safely.
  • a further hydraulic test is required where the container and closure must undergo internal hydraulic pressure for a period of 30 minutes with an internal pressure being applied of 1, to 2, Bar, and a further stacking test of the container at a height of 3, meters for a period of 28 days at a constant temperature no less than 40°, along with a environmental stress cracking test which tests the closure and seal for any stress cracking through a tube with screw threads on both ends, where two closures are threaded on and torqued up.
  • PFL 2323 In the tube is PFL 2323. The whole device is then merged into the respective PFL and stored at 40°C for at least 56, days. Any initiation of stress cracking is observed twice a week.
  • a closure is formed from five parts, a first part including a compartment to hold one product, the compartment being adapted to engage in the neck of a container, a second part which moves relative to the first part and has a means for opening a bottom wall of the compartment to release the product into the container, and a sealing cap which engages over the compartment part to seal the closure on the container.
  • Such a structure is relatively complicated and expensive to manufacture, requires the assembly of five separate parts as well as the introduction of a product into the compartment during assembly, and involves a number of separate actions in order to release the product in the compartment into the container and does not seal the container in the way required when packaging dangerous goods.
  • This multifunction closure with three-dimensional flexible sealing capabilities with a dispensing device incorporated has been invented for the dangerous goods and toxic chemical industry to provide a much safer system when packaging or using such harmful substances by sealing the container through a specially designed closure with a one or two-part flexible sealing wad which can be induction sealed or sealed by a pressure glue activated by heat onto the container at the time of the closure being applied to the container, and incorporates a dispensing mechanism in the closure that keeps apart toxic or harmful chemicals until the time of use in a separate isolated chamber with an activation mechanism which can be activated automatically when the closure is undone from the container, allowing the two or more substances to be dispensed into the container and mixed together by the operator at the time of use.
  • the closure body includes an outer cylindrical wall and a coaxial inner wall.
  • the closure is sealed onto the container through a flexible compression wad which carries a protective lamination which conforms to the exact contour of the closure internal protruding wedge ridge shape pressurizing the sealing wad and intern conforms to the exact shape of the three sealing neck spout edges, being the top inside wall, top lip rim and the top of the outside wall of the container.
  • the actual shape of the tapered angle of the top wall of the closure performs an important function by wedging the seal against the three surrounding sealing edge surfaces of the container, which in turn provides a seal, being the inside wall edge, the top rim lip and the outside edge of the neck spout of the container and as a result of the unique protruding wedge ridge shape in the underneath side of the closure, pressurizes the inside sealing edge of the container through internal forcing evenly the container neck walls to straighten and to become round so as the edges of the lip walls of the container are aligned with the closure caring the seal and when the closure is torque down on to the container, through engaging all three sealing spout edges of the container, in turn provides this airtight seal to be achieved between all three container wall edges and the closure seal.
  • the three-dimensional closure seal wad can be molded by forming the sealing material to the desired shape through pressure molding, prior to the assembly of the sealing wad into the closure.
  • the seal fits into an oversize recess groove provided in the wall of the closure which allows the seal to stay fully expanded in a relaxed position with large tolerances so that the container which is out of round and has variable and different neck dimensions and sealing spout wall thicknesses can still enter into the internal seal recess without any resistance
  • the container makes contact with the closure seal first in the relaxed state and when the closure is screwed further onto the container the container in turn picks up the sealing wad and carries it further into the unique protruding wedge ridge shape recess in the underneath side of the closure.
  • the seal engages with all three sealing edges of the container, in turn providing a successful airtight seal to be achieved between all of the three container neck spout wall edges and the flexible seal wad with the closure.
  • Another embodiment of the invention uses a similarly constructed molded sealing wad as described above, however it is laminated with an aluminium induction foil seal creating a two-part laminated wad induction seal system that seals the container through the closure and sealing wad and is induction sealed to the container at the time of packaging.
  • the lamination sealing material is specially produced for the resistance of all toxic or dangerous chemicals and is a flexible compression PE foam or the like, with an aluminium induction seal bonded to the underneath side of it which provides the safety tamper-proof evident part of the system, when the closure is screwed on to the container then a high frequency electrical current is applied creating heat to the top of the closure which in turn, bonds the induction foil attached to the sealing wad to the three edges of the neck spout of the container, being the inner side wall, the top lip of the wall and the outside wall creating a permanent or temporary bond of the induction material and sealing wad together to the container.
  • this induction sealing method can be achieved through having the aluminium induction foil formed to the desired shape independently from the PE foam seal or the like, by applying an induction seal coating or glue which bonds through heat or is activated by pressure and is applied to both sides of the aluminium foil or has been laminated to the PA film or laminated to the PE foam before or after molding the seal.
  • the seal coating can be bonded to the container either through the induction sealing method, or by applying heat onto the closure and seal, in turn activating the pressure glue creating the bond or through injecting hot steam into the container before applying the closure creating a vacuum seal or by preheating the container as practiced in the food industry to fill and package glass jars.
  • the closures sealing wad can be produced through pressure molding and is die-cut or knifed out at the same time creating the rip-line and pull-ring tab indentation where the aluminium induction foil or the PA foam sealing material will be ripped out from the middle of the seal wad area once the closure is removed from the container leaving the seal still bonded in place to the container.
  • Through pulling up the pull-ring tab leaver or the like in turn causes the aluminium induction film or PA lamination weakened portion of the sealing wad to rip open allowing the middle part of the seal wad to be partially or completely removed from the container, thus allowing the substances to be dispensed from the container.
  • sealing wad can be transferred or fitted into the closure at the time of injection molding the closure or could be molded through a two part cavity injection process at the same time, depending on the application of the closure and seal and what protective coating is required and what it is to be used for.
  • a further embodiment aspect of this invention there is a dispensing closure mechanism device that can dispense at least one product into the container, the dispensing device when activated dispenses the substance into the container which are held in the dispensing chamber and released into the container when the closure is undone from the container, the motion created through undoing the closure of the container automatically releases the bottom wall of the dispensing chamber, releasing the substance held in the chamber to release into the liquid, commencing the mixing of the two substances together ready for use.
  • the dispensing closure compartment is formed in such a way so it seals completely to the underneath side of the top inside edge of the closure body, having securing means to secure the device to the container, a compartment to contain the substances, at least one or more to be dispensed, the compartment being adapted to fit within the container and closure and being defined by a side wall, a top wall and a bottom wall, and releasing means moveable relative to the side wall, and the bottom wall by releasing and opening the bottom wall of the compartment to dispense the contents of the compartment into the container.
  • the closure and dispensing compartment is formed into two separate parts, one part being the closure body, the other part is the cylindrical wall of the dispensing compartment and the bottom spring hinge end wall and seal is moulded together in one piece.
  • the closure body is aligned with the dispensing compartment creating a sealed compartment when assembled together.
  • the compartment is fitted to the underneath side of the closure, the upper end of the dispensing compartment is formed with a flange which engages with the corresponding recess groove which runs around the inside of the closure body.
  • the dispensing closure compartment is filled with the substance which is desirable to dispense, then the bottom end wall is closed sealing the compartment together and is held in place by snap-fitting and locking to the internal rod which protrudes downwards from the inside top wall of the closure creating an airtight seal in the compartment, this allowing the chamber if needed to be vacuum or pressure sealed or flushed with different types of gases at the time of filling of the substance into the compartment.
  • the substance When the dispensing compartment is activated by undoing the closure from the container the substance releases from the chamber and dispenses into the container assisted through a spring hinge which also assists in the lining up of the sealing wall together when assembled, and when activated forces the bottom half of the compartment to completely open allowing the content to dispense from the compartment permitting contents thereof to be dispensed into the container to which the dispensing closure device is incorporated in or fitted to.
  • this method employed not only creates a much improved sealing child resistant system, but also a closure that is sealed completely with a much lower torque rate which provides a valuable tamper-proof system that is much easier for older or disabled people to remove when undoing this closure.

  • the top of the three-dimensional flexible compression sealing wad 2 is formed with angled facets being the outside facet 2e the top facet 2f and inside facet 2g and carries a internal recess running around the perimeter of the underneath side of the sealing wad which comprises of a top sealing wall 2a and two flexible sealing walls 2b and 2d when the flexible compression sealing wad 2 is assembled into the closure 1 the seal fits into a large oversize recess groove 13 provided in the inside wall edge of the closure body 1 which allows the flexible seal wad 2 to stay fully expanded in a relaxed position with large tolerances so that the container 4 which is out of round and has variably different neck dimensions and sealing wall thicknesses can still enter into the internal recess of the flexible seal 2 unheeded without resistance so when the closure is threaded onto the container 4 and the three sealing lip edges of the container 10 10a and 10b makes contact with the flexible sealing wad 2 still in its relaxed state, as the closure 1
  • the aluminum induction seal foil 3 is induction seal to all three walls surfaces of the spout neck of the container 4 through engaging the induction sealing head of the device, which in turn applies high voltage electricity creating heat directly onto the top of the closure body 1 thus ensuring complete permanent bond between all three surfaces of the closure sealing wad 2 and the container 4,
  • the child resistant tamper-proof evident inner portion of the sealing wad 2 is removed by placing your index finger underneath the flexible hinge pull -ring tab 21 held in the recess 21c in turn by holding the tab between your thumb and index finger 22 pulling in an upward direction, which in turn allows the aluminium induction seal 21b portion and the corresponding weakened recess groove carrying the rip line portion 21a to rip around the outer edge of the sealing wad 2 allowing the weakened portion of the sealing wad to open and be partially or completely removed from the container 4 exposing the contents of the container, but still leaving the outside perimeter of the sealing wad 2 bonded to the three sealing walls of the container, so the container can be re-sealed once again providing a reliable pressure seal as before.
  • this illustration shows a fourth embodiment of the invention the closure of this embodiment is designed particularly for use on a plastic or glass container having a threaded neck which is consistently out of round or formed severely out of shape through the manufacturing process, such as a beverage bottle or glass jar for example.
  • the closure comprises of single flat flexible sealing wad foam material laminated with a protected film to protect the foam seal, or can be laminated with an aluminum peel-able induction sealing film which can easily be removed with or without the seal wad still being attached.
  • FIG. 13 illustrations show a fifth embodiment of the invention this embodiment shows the closure 1 , threaded onto the container and has a unique oxygen scavenger device fitted into the recess 23 of the sealing wad, which works by eating up any oxygen entering the container 4 continuously, through the container being flushed with a mixture of two different gases at the time of packaging, which creates a cartelisation conversation between the palladium disk woven material or the like, and the incoming oxygen entering through the porous container walls which is common in such blow molded plastic polymer containers, and with the charge gases placed in the container.
  • This oxygen scavenger device woven palladium flat disk material 23a or the like is placed into the recess 23 formed into the sealing wad 2 and covered with a external micro thin porous breathable covering film 23b and is sonically welded to the sealing wad recess wall protecting the oxygen scavenger device from harmful substances in the container through coming in direct contact with it. It will also be appreciated that this oxygen scavenger device can be utilized in any of the combinations of the flexible pressure sealing wads previously mentioned with the same performance and filling techniques at the time of packaging.
  • Figures 14 15 and 16 illustrations show a first embodiment of the invention in which a container closure body 1 defined by an inside top wall rim la. and a cylindrical outside wall lb and inner rim angle side wall lc and Id with a tamper- proof evident band 8
