Abstract
A container suitable for containing a liquid composition and comprising an insert located in the neck of said container, and wherein when said container is filled with a liquid composition, zero headspace exists below said insert.
Description
- This application claims the benefit of U.S. Application Ser. No. 60/963,870 filed Aug. 7, 2007.
- The present invention relates generally to a container having zero headspace. More specifically, the present invention relates to an insert which achieves zero headspace within the container.
- As liquid compositions are packaged into consumer ready packages, air is commonly trapped at the top of the container before it can be sealed. The air trapped at the top of the container (headspace) results in an air bubble, which disrupts the composition within the bottle if the bottle is rotated or its orientation is changed. 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. 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 becomes costly and risks overall quality of the liquid product in the container.
- 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 (typically vinyl chloride) being used to lift and open vent orifices in a closure when internal pressure reaches a given threshold value. The venting method is heavily dependent on the type of liquid composition being vented in order to be operable. It also limits design options and prevents optimal dispensing of the liquid composition. 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.
- Generally, the aforementioned methods require manual expulsion of gases after filling, by way of a pump or compression of the container, which forces gases through a venting material. These methods are vulnerable to incomplete expulsion of gases and often result in backflow of gases into the container. Particularly, where gases are expelled by compression of a flexible container, when the container is allowed to return to its uncompressed position, some gas is likely to migrate back into the container.
- Therefore, a need still exists for a closure which creates zero-headspace during packaging, while preventing reintroduction of gas into the container. A need also exists to allow easy dispensing, from the same closure, of the contents of the package by a consumer.
- The present invention meets the aforementioned needs by providing a container suitable for containing a liquid composition and comprising an insert located in the neck of said container, and wherein when said container is filled with a liquid composition, zero headspace exists below said insert.
- 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. 8 is an enlarged side view of the upper portion of a container comprising a liquid composition, which illustrates substantial equilibrium on either side of a valve face, after insertion. - 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.
- The term “insert” as used herein, refers to a mechanism which a liquid composition may pass through under conditions of a sufficient pressure differential and which may be fixed within a container suitable for liquid compositions. A valve is one type of insert.
- The term “valve” as used herein, means a device for halting or controlling the flow of a liquid, gas, or other material through a passage, pipe, inlet, outlet, etc., which is activated when a sufficient pressure differential is exerted upon it.
- The term “substantial equilibrium” as used herein, means that the force exerted on either side of a surface is nearly equal, or equal. Under conditions of substantial equilibrium, the valve herein remains sealed. The absence of a pressure differential results in substantial equilibrium.
- The term “pressure differential” as used herein, means the pressure exerted on one side of the insert herein, such that the insert is activated, and is thereby permeable.
- The term “zero headspace” as used herein, refers to the space between the bottom surface of the insert and the top surface of the liquid composition which is located below the insert, within the container. Upon achieving zero headspace, there is no space between the bottom surface of (below) the insert and the liquid composition.
- In one embodiment, the insert employed to achieve zero headspace is a
valve 1, which is designed to be effectively inserted into theneck 2 of acontainer 3. Thevalve 1 is typically bonded or sealed to theinner wall 16 of theneck 2 by aretaining ring 5. Thevalve 1 generally comprises a flexible, resilient material, which can open to dispense fluid under the exertion of a pressure differential, and which is substantially impermeable to liquids and gases in the relative absence of a pressure differential. Thevalve 1 may be fabricated from thermoplastic elastomers based upon materials such as thermoplastic propylene, ethylene, urethane, styrene, and their halogenated counterparts. Similar valves are described in U.S. Pat. No. 5,439,143 and U.S. Reissue Pat. No. RE39,520. Further valves are commercially available from suppliers such as Liquid Molding Systems, Inc. of Crystal lake, Ill. - One type of
valve 1, as illustrated inFIGS. 2-4 , includes a flexiblecentral face 6 which has a concave configuration (when viewed from the exterior) and which defines two, mutually perpendicular, intersecting, dispensingslits 7 of about equal length. The intersectingslits 7 define four, generally sector-shaped,flaps 8 in the concave,central face 6. Theflaps 8 open outwardly from the intersection point of theslits 7, in response to increasing container pressure of sufficient magnitude (pressure differential), which can be achieved by compressing aflexible container 3, or upon insertion of thevalve 1 into theneck 2 of the container 3 (described in detail hereinafter). - The
valve 1 includes a skirt 10 (FIG. 4 ) which extends outwardly from thevalve 1central face 6. At the outer (upper) end of theskirt 10, there is a thin,annular flange 11 which extends peripherally from theskirt 10 in an angled orientation. Thethin flange 11 terminates in an enlarged, much thicker,peripheral flange 12 which has a generally dovetail shaped transverse cross section. - The lower surface of the
peripheral flange 12 is bonded to a retainingring 5, which extends upwardly to form acylinder 13, which has a length which is typically slightly longer than theneck 2 of thecontainer 3. Thecylinder 13 comprises aninner wall 14 and anouter wall 15. Theouter wall 15 of thecylinder 13 may comprise a matching means to seal theouter wall 15 of thecylinder 13 to a matching surface of theinner wall 16 of theneck 2 of thecontainer 3. The matching means may comprise threads, a clamping mechanism, a clipping mechanism, a bonding adhesive, or other means known in the art for creating a seal. - As discussed above, when gases are present in packages which contain liquid compositions, the pocket of gas at the top of the package often disrupts composition, either chemically, aesthetically, or both. Although other gases may be present in the liquid composition as suspensions or gas capsules, the pocket of gas at the top of the package can migrate throughout the liquid composition during shipping, which causes the aforementioned disruptions. This problem is solved by a zero headspace insert.
- In one embodiment, zero headspace is achieved by filling the
container 3 with aliquid composition 17 to alevel 18 at or above theshoulders 19 of thecontainer 3 as depicted inFIG. 5 . Upon filling, the container typically has a volume of gas 9 (air) which remains at the upper portion of thecontainer 3, typically above theshoulders 19 and in theneck 2. Thevalve 1 is inserted into theneck 2 to displace theliquid composition 17. As thevalve 1 descends into theneck 2, theliquid composition 17 is displaced in thecontainer 3, until thevalve 1 is forced to roll upwardly on itself and open, as depicted inFIGS. 6 and 7 . Theliquid composition 17 flows through the valve opening 4, and accumulates above thevalve 1, generally in theneck 2 of thecontainer 3. Thevalve 1 then returns to its sealed position as depicted inFIG. 8 , as thevalve 1 reaches substantial equilibrium. After thevalve 1 is inserted, and secured to theneck 2 via the matching means described hereinbefore, a cap (not depicted) may then be applied to thecontainer 3 as a closure by various means which are known in the art. - The zero headspace insert, described above, prevents gases, now above the
valve 1, from entering and disrupting theliquid composition 17 in thecontainer 3. This is particularly useful to prevent damage to liquid compositions which comprise patterns or designs, due to rotation of thecontainer 3, and migration of bubbles throughout theliquid composition 17. Of course, preservation of such patterns and designs are particularly relevant to liquid compositions which are packaged in transparent containers. Therefore, in one embodiment, thecontainer 3 is a transparent or semi-transparent container. - In use, in order to expel the
liquid composition 17 from thecontainer 3, thevalve 1 must be removable, or thecontainer 3 may be flexible. Accordingly, in one embodiment, thevalve 1 is removable via a removable matching means, such as threads, as discussed hereinbefore. In the case of personal care compositions, or other less viscous liquid compositions, a compressible container may significantly improve ease of expulsion of a liquid composition. Therefore, in another embodiment, thecontainer 3 is primarily made from a flexible plastic material such as polyethylene (PE), polypropylene (PP), or poly(ethylene terephthalate) (PET). Such materials may be fabricated as transparent, opaque, or semi-transparent containers. As discussed hereinbefore, compression of aflexible container 3 creates a pressure differential which is sufficient to expel theliquid composition 17 through thevalve 1 without its removal. - 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 in the Detailed Description of the Invention 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 document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this 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.
