Three-part closure sealing and dispensing device for all types of Containers

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...

AI Technical Summary

Benefits of technology

The invention is a closure for dangerous goods and toxic chemicals that has a flexible sealing wad and a separate dispensing mechanism. The closure seals the container through the flexible sealing wad and keeps the harmful substances separate until the time of use. The closure is designed to be safer and easier to remove for older or disabled people. The three-dimensional closure design uses a unique protruding wedge ridge shape to seal the container and keep the harmful chemicals separate. The closure can be easily assembled and snapped onto the container, creating a secure and tight seal.

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 recommendations.

Another proposal is outlined in US Patent Application No. 2011 / 0192818, for induction sealing containers, however in the way that it is proposed, it does not work on extruded blow moulded containers where the molding tolerances very extremely, and the surface and finish on the containers are not formed consistently and are out around with large inconsistent lip rim sealing the spout lip wall rim thickness variations.

However these type of closures with dispensing devices previously proposed are relatively unreliable as they do not address the sealing issues adequately in the way that this invention does and do not have any reliable pressure sealing methods or other safety tamper-proof evident or security feature solutions that prevents children tampering with any of the harmful or toxic chemical substances stored in the closure or the container.

In one of the previous proposals which is relatively complicated.

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.

I also personally have a previous U.S. Pat. No. 7,475,774, under Aron Joseph Clarkson, however the closures I proposed in this previous patent invention cannot be used for this purpose, as they are not designed to package such dangers toxic chemicals in this way, as the design structure and sealing capabilities of these closures cannot take these type of internal pressures required, and do not seal the container in a reliable or safe enough way, also the volume of chemicals substances which is required to dispense in this industry from such a closure device are much more than you can package in this type of dispensing compartment safely, and do not comply with the extreme UN recommendations which are governing this industry.
