Abstract
A closure assembly which comprises an orifice which comprises a venting material, and wherein said venting material is substantially permeable to gases and wherein said venting material is substantially impermeable to liquids.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/834,873 filed Aug. 2, 2006.
- The present invention relates generally to a venting closure. More specifically, the present invention relates to a venting closure assembly useful for venting gases and dispensing liquids.
- As liquid compositions are packaged into consumer ready packages, air is often times trapped at the top of the container before it can be sealed. The air trapped at the top of the container (headspace) often results in an air bubble, which disrupts the composition within the bottle if the bottle is rotated. In instances where a specific design is created within the liquid composition in the container, the air bubble can cause damage to the design during shipping. Additionally, many liquids are sensitive to gases, such as oxygen. When containers are filled with such liquids, the presence of atmospheric gases reduces shelf-life, and thereby increases costs to the manufacturer. Headspace can generally be reduced by “topping off” the container with a sufficient amount of the composition as to prevent air from remaining at the top of the container. However, this technique is difficult to automate, and therefore must typically be performed by hand. Additionally, “topping off” often results in overflow of the liquid composition, which creates a hazardous condition on a production line.
- A known method for eliminating headspace is to vent liquid-filled containers. One technique involves a pressure system comprising pieces of rubber, metal springs, and/or soft films (preferably vinyl chloride) being used to lift and open vent orifices in a closure when internal pressure reaches a given threshold value. Another technique is to provide elaborate passages in a closure whereby gases may leave the system but liquid losses are minimized. A third system, which may be called the pinorifice system, employs one or more tiny orifices in rubber, metal or plastic diaphragms which render the material permeable to gases. Yet another system, commonly called a positive displacement pump, or piston system, employs a mechanism which pushes a composition to the top of a container via a rising piston or pump. However, none of the aforementioned methods effectively eliminates headspace from a container.
- Therefore, a need still exists for a closure which allows for venting of gases during packaging, while eliminating escape of liquid contents and also eliminates headspace in a container. A need also exists to allow easy dispensing, from the same venting closure, of the contents of the package by a consumer. Additionally, a need exists for a closure which allows venting of gases in mass.
- The present invention meets the aforementioned needs by providing a closure assembly which comprises an orifice which comprises a venting material, and wherein said venting material is substantially permeable to gases and wherein said venting material is substantially impermeable to liquids.
- The present invention is also directed to a method of venting gases comprising the steps of filling a container with a composition, expelling gases through a venting material, and sealing the closure after headspace is eliminated.
- While the invention will be described in connection with certain embodiments, it will be understood that the invention is not limited to these embodiments. On the contrary, the invention includes all alternatives, modifications, and equivalents as may be included within the spirit and scope of the present invention.
- The accompanying drawings illustrate embodiments of the invention and, together with a general description of the invention given above, and the detailed description given below, serve to explain the invention.

FIG. 4 is a view of the top of the closure assembly; -
FIG. 5 is a front view of the closure assembly; -
FIG. 6 is a lateral cross sectional view of the top of the closure assembly. - While the specification concludes with claims that particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description.
- As used herein, the term “substantially gas-permeable,” means that the material described generally allows gases to pass through it.
- As used herein, the term “substantially liquid-impermeable,” means that the material described generally resists the movement of liquids through the material. Therefore, the material behaves as a barrier to liquids.
- As used herein, the term “substantially air-tight,” means that the seal generally resists the entry and escape of air/gases around the seal.
- Referring to the figures, and specifically
FIGS. 1 and 2 , a closure assembly 1 comprises abase 2, andlid 3. Thelid 3 is capable of sealing anorifice 4 in thebase 2. It is also contemplated that thebase 2 may be designed by employing more than one orifice. Thelid 3 may also comprise a sealing means 5 to reinforce the integrity of the seal around theorifice 4. The sealing means 5 may be a plug comprising a material selected from the group consisting of plastic, rubber, cork, or other material known in the art capable of creating a seal when applied to an orifice. Preferably, the seal is substantially air-tight when thelid 3 is in the closed position. - The
base 2 may be knurled or serrated on itsoutside surface 7 for ease of handling, and it is illustrated as having a securing means such asthreads 8, for securing to a matching means, such as threads, on a container. Preferably, thelid 3 is removable from theorifice 4, while remaining attached to thebase 2 at abending means 6. The bending means 6 may attach to thebase 2 with an attaching means comprising an adhesive, a hinge, a hooking mechanism, a matching means wherein an extension of the lid is inserted into the base at a coplanar location 11 on the base, or by another attaching means known in the art. The lid may also be molded directly to the base. - The average diameter of the
orifice 4 is preferably about 20% to about 60% of the average diameter of theinside wall 10 of thebase 2. Theventing material 9 comprises a material which is substantially gas-permeable and substantially liquid-impermeable. Non-limiting examples ofventing materials 9 are woven or non-woven fabrics, thin flexible plastics such as polyethylene, polypropylene, mylar, and polytetrafluoroethylene. Polytetrafluoroethylene is most preferred. Theventing material 9 has a preferred thickness of from about 10% to about 25% of the diameter of theorifice 4. - The
orifice 4 also comprises a means for securing the venting material in place. Theventing material 9 may be secured to the surface surrounding theorifice 4, either above or below theorifice 4, by applying an adhesive material to the edges of theventing material 9 and affixing theventing material 9 to thebase 2, either above or below theorifice 4. Where theventing material 9 is secured either above or below theorifice 4, theventing material 9 is slightly larger in average diameter than theorifice 4. Alternately, theventing material 9 may be secured inside theorifice 4 by lodging theventing material 9 in between threads, or by using an adhesive where theventing material 9 comes into contact with theinside wall 10 of theorifice 4. Where theventing material 9 is secured inside theorifice 4, theventing material 9 is preferably slightly less than the diameter oforifice 4. However, threads may also be cut into the inner walls oforifice 4, so that theventing material 9 is not smaller in average diameter than the average diameter of theorifice 4. Also, in another embodiment, theventing material 9 may be molded into theorifice 4 during fabrication of the closure assembly 1. - In operation, after a container is filled with a composition, the closure assembly 1 is secured to a container. Pressure within the container is increased by various means, and gases are released through the venting
material 9, and expelled through theorifice 4, which eliminates headspace. After gases are expelled, theorifice 4 is sealed by thelid 3. In a preferred embodiment, the lid comprises a sealing means 5 which is operable to puncture the venting material when thelid 3 is closed to seal theorifice 4. Pressure may be increased internal to theorifice 4 by build up of gases produced during reaction of various ingredients of the liquid composition, by applying a force to the exterior of the container to physically force gases/air through theorifice 4, or by other methods known in the art to create a pressure differential inside and outside of the container. In one embodiment, atmospheric pressure may be reduced external to the container to vent gases via a vacuum. - The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
- All documents cited herein are, in relevant part, incorporated herein by reference; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention. To the extent that any meaning or definition of a term in this written document conflicts with any meaning or definition of the term in a document incorporated by reference, the meaning or definition assigned to the term in this written document shall govern.
- While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is, therefore, intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
