The generally flat portion is structured to engage a corresponding portion that extends outward from a neck of the container.
Description
- This application claims priority to U.S. provisional application No. 61/257,171 filed Nov. 2, 2009, entitled “Anti-Backoff Closure/Container”, the contents of which are incorporated herein by reference.
- 1. Field of the Invention
- The invention relates generally to closures, containers and combinations thereof. More particularly, the invention relates to a closure assembly for use with a container and a combination of a closure assembly and a container that includes an anti-backoff mechanism along with a tamper evident retention band.
- 2. Background Information
- Drop lock tamper evident mechanical bands used on containers such as water/soda bottles and milk bottles normally spin with the related closure until the band engages the retention ring of the bottle. The vertical movement of the closure during unscrewing of the closure causes the band to engage the retention ring of the bottle and ultimately break and separate from the closure.
- High density bottles, such as HDPE bottles used in the dairy sector for packaging milk for retail, generally have a very thin sealing area due to the inherent properties of the bottle and cap (closure) material. As a result of such thin sealing area, any vertical movement of the cap with respect to the bottle may allow leaking of the fluid contained therein from the bottle or conversely allow contaminants to enter the bottle. Such vertical movement of the cap may commonly occur in known cap and retention ring designs without any indication (such as through visual indication of a broken retention band) that such unsealing of the container has occurred.
- Accordingly, there exists a need for an improved cap and bottle combination that overcomes the shortcomings of the known designs.
- As one aspect of the invention, a closure assembly for use with a container is provided. The closure assembly comprises: a generally cylindrical cap portion and an annular skirt extending from, and frangibly coupled to, the cap portion. The annular skirt comprises a number of lugs extending inward from an inner portion of the annular skirt. At least one lug of the number of lugs extends circumferentially along the inner portion and includes a top portion, a bottom portion and a generally flat portion extending therebetween. The generally flat portion is structured to engage a corresponding portion extending outward from a neck of the container.
- The flat portion of the at least one lug may be oriented generally perpendicular to the top portion of the at least one lug. The at least one lug of the number of lugs may comprise an inclined front portion opposite the generally flat portion. The top portion of the at least one lug of the number of lugs may comprise a generally flat surface structured to engage a corresponding portion extending outward from the neck of the container. The bottom portion of the at least one lug of the number of lugs may comprise a surface generally inclined inward and upward. The annular skirt may be frangibly coupled to the cap portion via a number of frangible connection points. The annular skirt may be frangibly coupled to the cap portion via a membrane. The number of lugs may comprise a plurality of lugs of identical or similar form as the at least one lug.
- As another aspect of the invention, a closure in combination with a container is provided. The combination comprises a container having a neck portion disposed about an opening. The neck portion having a number of retention lugs extending outward therefrom, at least one retention lug of the number of retention lugs having a generally flat portion. The combination further comprises a closure assembly comprising: a generally cylindrical cap portion threadedly coupled to the neck portion of the container and an annular skirt extending from, and frangibly coupled to, the cap portion. The annular skirt comprises a number of lugs extending inward from an inner portion of the annular skirt. At least one lug of the number of lugs extends circumferentially along the inner portion and includes a top portion, a bottom portion and a generally flat portion extending therebetween. The generally flat portion of the at least one lug cooperatively engages the flat portion of the at least one retention lug in a manner that inhibits movement of the at least one lug with respect to the at least one retention lug in a direction corresponding to removing the cap portion from the neck portion.
- The neck portion may comprise a retention ring that extends outward therefrom and the top portion of the at least one lug may cooperatively engage the retention ring in a manner that inhibits movement of the at least one lug with respect to the retention ring in a direction corresponding to removing the cap portion from the neck portion. The engagement between the generally flat portion of the at least one lug and the flat portion of the at least one retention lug may result in separation of the annular skirt from the cap portion upon rotation of the cap portion with respect to the container in a direction corresponding to removing the cap portion from the container. The rotation may comprise one degree or less of rotation. The annular skirt may be moveable on the neck portion of the container from a first position in which the annular skirt is coupled to the cap portion to a second position in which the annular skirt is uncoupled and spaced a distance from the cap portion when the cap portion is tightly threadedly coupled to the neck portion.

FIGS. 1A-1D show aclosure assembly 10 in accordance with a non-limiting embodiment of the present invention.Closure assembly 10 includes acap 12 and a retention ring in the form of anannular skirt 14 extending fromcap 12 according to a non-limiting embodiment of the present invention.Annular skirt 14 is frangibly coupled to cap 12 via one or more frangible connection points 15, frangible membrane(s), or other suitable mechanism(s), and includes a number oflugs 16 disposed on an inward facing portion 17. As used herein, the nomenclature “(s)” shall be used to represent one or more. As also used herein, the term “number” shall mean one or an integer greater than one (i.e., a plurality). As shown in the cut view ofFIG. 1C and the detailed view ofFIG. 1D , at least one, and preferably all, of the number oflugs 16 extend circumferentially a distance d along inward facing portion 17 and include a generallyflat portion 18 at one end, a generallyinclined portion 19 at an opposite end, and top andbottom portions portions flat portion 18 is oriented generally parallel to the axis (not shown) around whichclosure 10, and thus cap 12, would be rotated during installation or removal from a container. It is to be appreciated, however, thatflat portion 18 may be oriented at other angles with respect to such axis, as long as such angle is not perpendicular to such axis, without varying from the scope of the present invention.Top portion 20 preferably comprises a generally flat surface oriented generally perpendicular to the axis (not shown) around whichclosure 10 would be rotated during installation and removal. Accordingly, in the example embodiment shown,flat portion 18 is oriented generally perpendicular totop portion 20.Bottom portion 21 preferably comprises an inclined bottom surface inclined generally inward and upward towardcap 12. The general purpose and function of thelugs 16 as well as their specific structure is discussed in detail below. - As shown in
FIG. 1C ,cap 12 includes a threadedportion 22 on an interior surface (not numbered) that is adapted to cooperatively engage a corresponding threaded portion of the neck of a container, as will be discussed in further detail below. -
FIGS. 2A and 2B show aneck portion 30 andopening 32 of a container 33 (only partially shown) such as that commonly used for storage of a liquid (e.g., without limitation, milk) in accordance with a non-limiting embodiment of the present invention.Neck portion 30 includes a threadedportion 34 having a number of individual threads 35 disposed at or near theopening 32 that cooperatively engage threadedportion 22 ofcap 12 whenclosure assembly 10 is installed on the container havingneck portion 30.Neck portion 30 further includes a number of retention lugs 36 disposed generally aroundneck portion 30 below the threadedportion 34, and a generally outward protrudingretention ring 37 disposed therebetween. As shown inFIG. 2B , at least one, and preferably all, of retention lugs 36 includes a generallyflat portion 38. Additionally, each retention lug preferably includes aninclined portion 40. Although shown as a generally triangular shaped member, it is to be appreciated that one or more of retention lugs 36 could be of different general shape while still including a flat portion 38 (e.g., without limitation, rectangular) without varying from the scope of the present invention. -
FIGS. 3A-3D show theclosure assembly 10 andneck portion 30 previously described installed together via cooperative engagement of threaded portions 22 (FIG. 1C) and 34 (FIG. 2A ).closure assembly 10 is preferably installed onneck portion 30 via a rotational installation process in which closure assembly is rotated and thus tightened down onneck portion 30. During such installation, lugs 16 move downward onneck portion 30 toward the container. Aslugs 16encounter retention ring 37, theinclined bottom portion 21 oflugs 16 tend to assist in each oflugs 16 passing overretention ring 37. In contrast, the generally flattop portion 20 of eachlug 16 inhibits passing of thelugs 16 overretention ring 37, such as would attempt to occur if closure assembly were to be unscrewed from, and thus moved axially away from,neck portion 30. - After passing
retention ring 37, each of thelugs 16 ofannular skirt 14 encounter retention lugs 36 ofneck portion 30. As each oflugs 16 encounter retention lugs 36, theinclined portion 19 of eachlug 16 tends to assist in each oflugs 16 passing over retention lugs 36 asclosure assembly 10 is rotated ontoneck portion 30. Similarly, when structured as shown in the FIGS., theinclined portion 40 of eachretention lug 36 tends to also assist in the passage of eachlug 16 thereover. In contrast, the generallyflat portion 18 of eachlug 16 inhibits passing of alug 16 over a respective one of the retention lugs 36, such as would attempt to occur if closure assembly were to be rotated in a direction corresponding to removal fromneck portion 30. - As shown in the detailed cut view of
FIG. 3D , when theclosure assembly 10 is threaded and sufficiently tightened down onneck portion 30, the flat 18 of at least onelug 16 onannular skirt 14 engages theflat portion 38 of a corresponding one of the number of retention lugs 36 onneck portion 30, thus restricting rotational movement ofclosure assembly 10 in a direction that would open the container. Such tight interaction between flat 18 andflat portion 38 provides for theannular skirt 14 to break away fromcap 12 upon slight horizontal (rotational) movement (preferably less than a degree of rotation) ofcap 12 with respect toneck portion 30, as whencap 12 is unscrewed fromneck portion 30 upon opening the container. Such quick break away of theannular skirt 14 resulting from the present invention is in contrast to known designs which generally rely on vertical movement of the cap away from theneck portion 30, and as such generally require at least 90 degrees of cap rotation before separation of the annular skirt. - Accordingly, the present invention provides an indication when
cap 12 has been rotated only a small amount relative toneck portion 30 of the container and thus possibly compromised the sealed contents. Such indication is provided by the visible separation between theannular skirt 14 andcap 12. The separation between theannular skirt 14 andcap 12 may be magnified by providing an increased spaced region 42 (FIG. 3B ) onneck portion 30 that allows forannular skirt 14 to drop a predetermined distance (not numbered) down fromcap 12 upon separation fromcap 12, even whencap 12 is disposed at its most tightly threaded position onneck portion 30. Accordingly, such separation would still be obvious to an observer even ifcap 12 has been removed (either partially or completely) and retightened down on the container. - While embodiments of the invention have been described herein, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of invention which is to be given the full breadth of the claims appended and any and all equivalents thereof.
