Benefits of technology

[0031]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

Problems solved by technology

A number of proposals have previously been made for the sealing of these types of industrial containers to be constructed in a way that the closure seals the container with different sealing methods and by employing different types of sealing materials, however these proposals do not work satisfactory and are not reliable enough under many of the different conditions which these types of products are subjected to, and do not comply in accordance with the UN recommended safety guidelines regarding the packaging and handling of such harmful chemicals or the like.
There have also been a few proposals that endeavour to separate two different products until the moment of use at which time one product is mixed with the other in the container, however these existing closures that have been proposed can only dispense very small volumes accurately and reliably and do not seal the containers sufficiently to withstand the vigorous testing requirements recommended by the UN.
So with such testing procedures recommended by the UN many previous solutions proposed are unable to withstand such extreme testing and are not suitable to be employed in the dangerous goods category as under these extreme conditions many closures and seals fail under these tests resulting in spilling the substance held in the container out which in turn can cause much harm to anyone coming into contact with these dangerous substances.
However these types of closures which are employed to seal beverage bottles like this one, are only suitable for containers which are matching the exact dimensions and profile of the specified closure where they have very minimal tolerance differentials and can not be used on such extruded below molded containers which are used in the dangerous good industry.
They also do not have an independent sealing wad which protects the closure from coming into contact with aggressive substances stored inside the container and are not suitable or recommended for sealing dangerous goods and do not comply with many of the UN recommendation

second embodiment

[0055]Referring to FIGS. 45 and 6 illustrates the invention, this embodiment is similar to that shown in FIGS. 12 and 3 and illustrates the invention in which a container closure body 1 defined by a inside top wall rim 1a and a cylindrical outside wall 1b and inner rim angle side wall 1c the container has a sealing spout top lip 10 and a sealing outer spout wall 10a with a sealing inner spout wall 10b and external threads that the closure is held onto the container by, except where the three-dimensional flexible sealing wad 2 has been completely inserted into the underneath top portion of the closure body 1 and is formed in such a way as to engage the container 4 when the closure 1 is threaded onto the container neck, by in turn forcing the flexible sealing wad fingers 2a 2b 2c and 2d to flex when coming into contact with all three sealing spout wall's 1010a and 10b of the container 4 through in turn torque up further the closure 1 applying increasing pressure to compress and sandwi...

third embodiment

[0060]Referring to the drawings, FIGS. 78 and 9 this illustrates of the invention in which is similar to that shown in FIGS. 45 and 6, except that the three-dimensional flexible sealing wad 2 has been formed with an aluminum induction sealing foil lamination 3 to the underneath side of the sealing wad 2 or coated with a heat activation substance which can be bonded through either induction seal methods or activated by heat or hot steam at the time of the packaging process.

[0061]The child resistant tamper-proof evident security feature has been formed in the same way by creating a recess groove 21a which runs around the outer top surface of the inside perimeter edge of the sealing wad 2 formed in such a way to create a weakened indentation rip line created at the time of molding the seal 2 through knife cutting partially into the top groove 21a side only of the sealing wad foam 2 but not cut all the way through to weaken or cause damage to the aluminium induction film seal 3 thus pro...

fourth embodiment

[0066]Referring to FIGS. 1011 and 12 this illustration shows 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.

[0067]In this cross-section elevational view shows the flat one piece flexible compression sealing wad 5 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 over size flexible seal wad 5 to stay fully expanded in a relaxed position with large tolerances so that the...

Abstract

A container closure device with a flexible three-dimensional formed sealing wad with a circumferential ridge, the closure body (1) is formed with a top wall and a cylindrical wall, wherein the top wall has a circumferential trapezoidal groove on the inner side of its rim, adjacent to the cylindrical wall. A sealing wad (2) is arranged below the inner side of the top wall of the closure body, whereby the ridge is located under the groove and has an internal circumferential recess in the ridge running around the perimeter of the underneath side of the sealing wad, serving to receive the edge of the spout forming the opening of the container, whereby the protruding ridge is oversized compared to the groove, the width of the recess is reduced and compressed when the ridge is forced into the groove. The recess has sealing fingers and on its inner and outer side walls which creates the seal with the container.

Description

FIELD OF THE INVENTION[0001]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.BACKGROUND OF THE INVENTION[0002]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 a...
