- the upper and lower portions of the lid assembly are adapted to cooperatively form a tight seal around the lower dispensing opening when the upper sealing portion 16 is biased to a closed position.
- this sealing relation is effected by the cooperative lowering of the upper sealing portion 16 into sealing contacting relation with the raised sealing lip 38 disposed around the lower dispensing opening 34 .
- Such a sealed relation in the normally closed position aids in the protection of container contents that are required to remain moist such as pre-saturated wipes and the like that are susceptible to performance degradation due to evaporation.
- the interior circumferential surface 82 of the upper sealing portion 16 may include a circumferential guide groove 78 .
- the guide groove 78 is adapted to engage the circumferential guide ridges 46 ( FIG. 2A ) projecting from wall of the lower portion 14 when the upper and lower portions 16 , 14 are mated such that the circumferential guide ridges 46 are dimensioned ride within the circumferential guide groove 78 .
- the guide groove 78 is made up of a multiplicity of slots 79 arranged in a discontinuous circumferential arrangement around the interior circumferential surface 82 .

- the guide groove may be a continuous slot.
- the slots 79 forming the guide groove are preferably slightly angled relative to the upper surface 70 so as to have a sight change in elevation along their length. Due to the angle of the slots 79 , as the upper sealing portion 16 is rotated towards the open position ( FIGS. 5A and 5B ), the circumferential guide ridges 46 riding within the slots 79 act as camming surfaces thereby forcing the upper and lower portions 16 , 14 apart, in opposite directions.
- the camming action between guide ridges 46 and the guide groove 78 forces the upper sealing portion 16 in a direction away from the lower base portion 14 , which remains stationary.
- the camming action between the guide ridges 46 and guide grooves 78 forces the upper and lower portions 16 , 14 back towards contacting relation with one another.
- the relative arrangement of the guide grooves 78 and the guide ridges 46 may be reversed if desired. That is, the guide ridges 46 may be carried on the interior circumferential surface 82 of the upper sealing portion 16 and the guide groove 78 may be carried on the circumferential wall 33 of the lower base portion 14 .
- the elevation change of the upper sealing portion between the open and closed positions brings the sealing lip 38 into contacting sealing relation with the interior of the upper sealing portion to facilitate a close sealed relation.
- the second side 74 of the upper sealing portion 16 is placed into contacting sealing relation with the sealing lip 38 that bounds the lower dispensing opening 34 .
- the contents of the container 12 are protected from the environment outside the container 12 , and vice versa.
- the lid is moved to the open position, the second side 74 of the upper sealing portion 16 is raised away from the sealing lip 38 without interference.
- the lower base portion 14 may include an arcuate guide groove 44 in the upper surface 30 .
- the arcuate guide groove 44 is adapted to receive a guide post 60 ( FIG. 4B ) that projects downwardly from the upper sealing portion 16 .
- the guide post 60 rides in the arcuate guide groove 44 to maintain the lateral position of the upper sealing portion 16 with respect to the lower base portion 14 as the former is rotated to place the lid assembly 10 is an open or closed position.
- the length of the arcuate guide groove 44 may be dictated by the angle of rotation required to place the lid assembly 10 in an open position, and thus by the dimensions of the lower dispensing opening 34 .
- the dimensions of the lower dispensing opening 34 are such that a like-dimensioned upper dispensing opening 66 located on the upper sealing portion 16 may be rotated through approximately 90° to fully expose the lower dispensing opening when in an open position, and to fully seal the same when in a closed position. If a narrower lower dispensing opening 30 is utilized (along with a correspondingly narrower upper dispensing opening 66 ), a smaller minimum angle of rotation may be used to fully open and seal the lid assembly 10 .
- the arcuate guide groove is preferably at least long enough to accommodate the guide post 60 through this angle of rotation.
- the container 12 may be adapted to hold a continuous sheet of a plurality of wipes 53 , each individual wipe 53 being separated from an adjacent wipe by a line of perforation ( FIGS. 5A and 5B ). As a wipe 53 is pulled through the dispensing aperture 52 having a star-like configuration, the relatively narrow opening imparts tension on the wipe.
- the tension imparted is such that after a line of perforation is pulled through the dispensing aperture 52 , the adjacent wipes will tear along the line of perforation, thereby releasing a single wipe 53 for use, while retaining the formerly adjacent wipe within the container 12 with a portion thereof extending through the dispensing aperture 52 .
- the dispensing aperture 52 may also be adapted to efficiently and effectively dispense other materials held within the volume of the container 12 .
- the dispensing aperture 52 may consist of a plurality of openings, mesh, or grid, which may be effective for dispensing powders, granules, or other like particulate matter, or liquid matter from the container 12 and through the dispensing aperture 52 .
- the dispensing aperture 48 may include a spout that may be contained within the volume of the cavity defining the lower dispensing opening 34 . A spout would facilitate the pouring of liquids (as well as particulate matter) while minimizing spillage.
- the lower dispensing opening 34 may be entirely open, and not include the dispensing plate 49 , thereby allowing a user to insert a scoop or like instrument through the lower dispensing opening and into the interior of the container 12 in order to manually remove the material held therein.
- the dispensing plate 49 may be removable and interchangeable with a plurality of dispensing plates, each bearing a different dispensing aperture 52 . This modular design would permit a user to employ the lid assembly 10 of the present invention with containers for a number of different materials.

Abstract
A lid assembly for a container that effectively seals the contents of the container from the environment and the environment from the contents. The lid assembly includes an upper sealing portion and a lower base portion that are mated together coaxially. Once mated together and secured to the container, the upper portion may be rotated relative to the lower portion to expose the contents of the container through the alignment of dispensing openings in each of the upper and lower portions. During rotation of the sealing portion from a closed position to an open position, the sealing portion is elevated relative to the base portion to form a separation between the sealing portion and the base portion while concurrently aligning the dispensing openings to permit withdrawal of the contents of the container. Upon release of the opening force, the sealing portion retreats away from the elevated position towards the base portion while simultaneously covering and sealing the dispensing opening in the base portion.
Description
- This invention relates to a lid assembly for sealing a container. More particularly, the invention relates to a self-closing sealing lid assembly incorporating a base portion and a sealing portion that rotate respectively to expose the contents of the container. When in a closed position, a seal is created between the base and sealing portions in order to protect the contents of the container from the environment as well as isolating the outside environment from the contents.
- The present invention provides advantages and/or alternatives over the prior art by providing a lid assembly for a container that effectively seals the contents of the container from the environment. The lid assembly includes an upper sealing portion and a lower base portion that are mated together coaxially. Once mated together and secured to the container, the upper portion may be rotated relative to the lower portion to expose the contents of the container through the alignment of dispensing openings in each of the upper and lower portions. During rotation of the sealing portion from a closed position to an open position, the sealing portion is elevated relative to the base portion to form a separation between the sealing portion and the base portion while concurrently aligning the dispensing openings to permit withdrawal of the contents of the container. Upon release of the opening force, the sealing portion retreats away from the elevated position towards the base portion while simultaneously covering and sealing the dispensing opening in the base portion.
- According to one aspect, the lid assembly may include a torsion spring, or like biasing element, that returns the lid assembly to a closed position when the rotational force used to open the lid assembly is removed.
- According to another aspect, upon rotation, the upper and lower portions may translate axially relative to one another such that when in a closed position, the lower dispensing opening is sealed against the upper sealing portion.
- According to a potentially preferred feature, the upper and lower portions of the lid assembly may incorporate an integral elevation adjusting camming assembly wherein one of the lid portions incorporates one or more male camming members adapted to ride within complimentary angled tracks on an opposing surface of the other lid portion such that relative rotation of the lid portions causes a relative translation in elevation between the portions as the camming members ride within the tracks.
- According to another potentially preferred feature, the lower portion portions of the lid assembly incorporates a depressed well at least partially surrounding the content withdrawal opening with a raised lip disposed at least partially around the depressed well. The raised lip enhances the seal around the depressed well when the upper portion rotates to the closed position.
- The accompanying drawings which are incorporated in and which constitute a part of this specification illustrate several exemplary constructions and procedures and, together with the general description given above and the detailed description set forth below, serve to explain operational principles wherein:

- Turning now to the drawings,
FIGS. 1 and 1 A depict an exemplary construction of alid assembly 10 adapted for attached relation to acontainer 12. It is contemplated that thecontainer 12 may be of circular cross-section. However, thecontainer 12 may be of polygonal or other cross-section as desired. By way of example and not limitation, thecontainer 12 may have a square, hexagonal, or octagonal cross-section. As illustrated, thecontainer 12 includes a closedend 18 and anopen end 20, theopen end 20 being adapted to releasably engage the lid assembly 10 (discussed in further detail below). Thecontainer 12 may be adapted to hold a volume of materials (not shown), including for example, liquid, powders, granules, or sheet products such as wiping cloths or the like. Thecontainer 12 andlid assembly 10 securely attach together in such a way that the material may be held therein without spillage. By means of example only, and not limitation, thecontainer 12 and/orlid assembly 10 may be constructed of plastic or other polymeric materials, glass, metal, or any other suitable structural material. According to one potentially preferred construction, thecontainer 12 and/or thelid assembly 10 may be constructed of a hard, injection-molded plastic. - In the illustrated construction, the
lid assembly 10 includes a lower orbase portion 14 and an upper or sealingportion 16. Each of the lower andupper portions upper sealing portion 16 is an incrementally greater diameter than thelower base portion 14 such that the lower andupper portions lower base portion 14 resides in male relation within the volume of the upper sealing portion 16 (discussed in greater detail below). - As illustrated in
FIG. 1A (and as will be discussed in further detail below) ahelical torsion spring 100 is adapted for disposition in substantially nested relation within a molded depression forming aspring bore 40 in thelower base portion 14. As will be described further hereinafter, thetorsion spring 100 engages acentral cylinder 62 which projects downwardly from theupper sealing portion 16 such that a torsional biasing force is established between the upper and lower portions of the assembly. -

Thebody 32 includes a substantially planar firstupper surface 30 that intersects acircumferential wall 33 at the perimeter of the firstupper surface 30. A slightly raisededge 36 is preferably disposed at least partially around theupper surface 30 at the intersection with thecircumferential wall 33 to facilitate sealing. From the perimeter of the firstupper surface 30, thecircumferential wall 33 extends in a downward direction to aflange 48 that extends radially from thecircumferential wall 33. By way of example and not of limitation, as depicted inFIG. 2A , theflange 48 may be hexagonal. Alternatively, theflange 48 may be of any polygonal or other shape, as may be desired. Theflange 48 preferably includes a knurledperipheral edge 50. The knurledperipheral edge 50 and the angled, polygonal shape of theflange 48 may serve to assist a user in attaching thelower base portion 14 to thecontainer 12 by providing greater leverage and grip. - According to the illustrated and potentially preferred embodiment, the
lower base portion 14 includes alower dispensing opening 34 defined by a cavity formed within the firstupper surface 30, and disposed between theaxis 36 and the periphery of the firstupper surface 30. In the preferred construction, a raised sealinglip 38 may project from the firstupper surface 30, at least partially around thelower dispensing opening 34. The cavity defining thelower dispensing opening 34 extends downwardly from the firstupper surface 30, and in a potentially preferred embodiment, terminates in a dispensingplate 49. - The dispensing
plate 49 may include a dispensingaperture 52. The dispensingaperture 52 is an opening in the dispensingplate 49 that allows access to the interior of thecontainer 12 when thelid assembly 10 is secured to thecontainer 12 and is placed in an open position. According to a contemplated embodiment, as depicted inFIG. 2A , the dispensingaperture 52 may be shaped in a star-like configuration with a plurality of arms projecting outwardly from a central bore. By means of example and not limitation, this star-like configuration is contemplated for use with a container intended for dispensing sheet products, such as woven or non-woven wipes. - Again referring to
FIGS. 2A and 2B , it is contemplated that a plurality of male camming members in the form ofcircumferential guide ridges 46 may be disposed about thecircumferential wall 33 of thelower base portion 14. Thecircumferential guide ridges 46 may be substantially linear projections that are distributed about thecircumferential wall 33, and are aligned substantially parallel with the firstupper surface 30. In a potentially preferred embodiment, each of thecircumferential guide ridges 46 may be substantially equidistant from the firstupper surface 30. In an alternative embodiment, each of thecircumferential guide ridges 46 may be of varying distances from the firstupper surface 30. These guideridges 46 may act as camming surfaces which cause theupper sealing portion 16 to rise relative to thelower base portion 14 as thelid assembly 10 is rotated to an open position, and cause theupper sealing portion 16 to lower relative to thelower base portion 14 when rotated to a closed position (discussed in further detail below). - As indicated previously, the
lower base portion 14 may include a spring bore 40 formed in the firstupper surface 30, the spring bore 40 being dimensioned to accommodatetorsion spring 100 within its depth (FIGS. 3A and 3B ). The spring bore 40 may be aligned substantially coaxially with the axis of thelower base portion 14. Communicating with the spring bore 40 is aspring extension groove 42, formed in the firstupper surface 30 and extending tangentially outward from the spring bore 40. The spring bore 40 and thespring extension groove 42 may terminate in aspring shoulder 54, upon which thetorsion spring 100 rests within the spring bore 40. As illustrated inFIG. 3B , the spring bore 40 may be defined by a first diameter to a depth coinciding with thespring shoulder 54. It is contemplated that the spring bore 40 may extend beyond and through thespring shoulder 54, thereafter defined by a second, narrower diameter portion. As best illustrated inFIG. 3B , the narrowed portion of the spring bore 40 defines ahollow nipple 41.Hollow nipple 41 may extend in a downward direction beyond the bottommost extent offlange 48. So constructed, when thelid assembly 10 is attached to thecontainer 12, thehollow nipple 41 may project into the interior of thecontainer 12. By means of example only, thehollow nipple 41 may engage the center of a cylindrical roll of wipes to maintain its position coaxial with thecontainer 12. - The
torsion spring 100 may include a helical coil portion and atangential extension 102, which projects outwardly from a first end of the coil in a substantially tangential direction. Thetorsion spring 100 may further include atorsion bar 104 in a pig tail configuration that extends inwardly from the second end of the coil at least partially across the coil. As will be described further hereinafter, thetorsion bar 104 is adapted to be held within thecentral cylinder 62 projecting downwardly from the upper portion of the assembly. -
FIGS. 4A and 4B depict a potentially preferred embodiment of theupper sealing portion 16 of thelid assembly 10.FIG. 4A is a top plan view taken generally alongline 4A-4A inFIG. 1A .FIG. 4B depicts a side view. Theupper sealing portion 16 is preferably substantially cylindrically shaped with a hollow interior and a central axis. However, other geometries as may be desired can also be utilized. By way of example only, theupper sealing portion 16 may be polygonal in shape with a hollow cylindrical interior. Theupper sealing portion 16 may define a secondupper surface 70, which itself includes afirst side 72 and a second side 74. Thefirst side 72 faces away from thelower base portion 14 when the upper andlower portions upper surface 70 from thefirst side 72, facing thelower base portion 14 when it is mated to theupper sealing portion 16. The hollow interior of theupper sealing portion 16 may be defined by the second side 74 and a circumferential downwardly projectingwall portion 80 that intersects and extends away from the secondupper surface 70. Theupper sealing portion 16 also includes an upper dispensing opening 66 defined by a cavity formed in the secondupper surface 70 between the axis 90 and the periphery of the firstupper surface 70. - Referring again to
FIGS. 4A and 4B , theupper sealing portion 16 may include ahandle 68 that projects outwardly from thefirst side 72 of the secondupper surface 70. In a potentially preferred embodiment, thehandle 68 may be a protuberance that extends radially in a direction from the central axis of the upper sealing portion, across thefirst side 72 towards the intersection with the downwardly projectingwall portion 80. It is contemplated that thehandle 68 may include a plurality of such radially extending protuberances, which may intersect at or near the axis 90. So configured, thelid assembly 10 may be easily and effectively rotated to between an open and a closed position. - As best illustrated in
FIGS. 4B, 5B and 6B, it is contemplated that thecentral cylinder 62 projects away from the second side 74 of theupper sealing portion 16 and is coaxially aligned with the central axis. Thecentral cylinder 62 may be of a substantially split construction including aspring engagement groove 76 that is cut through thecentral cylinder 62. When the upper andlower portions lower base portion 14 being within the volume of the interior of theupper sealing portion 16, thecentral cylinder 62 may extend through the coil of thetorsion spring 100 with thespring engagement groove 76 holding thetorsion bar 104. Thespring engagement groove 76 is cut to a depth along thecentral cylinder 62 sufficient to accept thetorsion bar 104 therein and thereby secure thetorsion bar 104 within thecentral cylinder 62. So positioned, a rotational force applied to theupper sealing portion 16 will bias thetorsion spring 100 while thetangential extension 102 is secured within thespring extension groove 42. As such, it is contemplated that thetorsion spring 100 may be in an un-biased condition when theupper sealing portion 16 is placed in a closed position (FIG. 6A ), while thetorsion spring 100 will be biased as theupper sealing portion 16 is rotated towards an open position (FIG. 5A ). Thus, when the rotational force applied to theupper sealing portion 16 is released, thetorsion spring 100 will tend towards its un-biased condition. In so doing, thetorsion spring 100 will apply a rotational force between the upper andlower portions torsion bar 104 and thetangential spring extension 102. This rotational force will tend to return theupper sealing portion 16 to its original, closed position. - The upper and
lower portions FIGS. 5A and 5B , and 6A and 6B. InFIGS. 5A and 5B , thelid assembly 10 is depicted as being in an open position. InFIGS. 6A and 6B , thelid assembly 10 is depicted as being in a closed position. As illustrated, when theupper sealing portion 16 is in its closed position, the upper andlower dispensing openings FIG. 6A . In this position, the firstupper surface 30 of thelower base portion 14 blocks access to the interior of thecontainer 12 through theupper dispensing opening 66. When theupper sealing portion 16 is in an open position, the upper andlower dispensing openings FIG. 5A ). So aligned, the interior of thecontainer 12, and thus the materials held therein, may be accessed by a user. The materials held within thecontainer 12 may then be effectively removed. - As indicated previously, according to a particularly beneficial feature of the invention, the upper and lower portions of the lid assembly are adapted to cooperatively form a tight seal around the lower dispensing opening when the
upper sealing portion 16 is biased to a closed position. In the preferred construction this sealing relation is effected by the cooperative lowering of theupper sealing portion 16 into sealing contacting relation with the raised sealinglip 38 disposed around thelower dispensing opening 34. Such a sealed relation in the normally closed position aids in the protection of container contents that are required to remain moist such as pre-saturated wipes and the like that are susceptible to performance degradation due to evaporation. - In order to achieve the desired sealed relation, it is contemplated that the interior
circumferential surface 82 of theupper sealing portion 16 may include acircumferential guide groove 78. As best illustrated inFIG. 7 , theguide groove 78 is adapted to engage the circumferential guide ridges 46 (FIG. 2A ) projecting from wall of thelower portion 14 when the upper andlower portions circumferential guide ridges 46 are dimensioned ride within thecircumferential guide groove 78. - According to the illustrated construction, the
guide groove 78 is made up of a multiplicity ofslots 79 arranged in a discontinuous circumferential arrangement around the interiorcircumferential surface 82. Each of the slots is adapted to accept acorresponding guide ridge 46. Alternatively, the guide groove may be a continuous slot. As shown, theslots 79 forming the guide groove are preferably slightly angled relative to theupper surface 70 so as to have a sight change in elevation along their length. Due to the angle of theslots 79, as theupper sealing portion 16 is rotated towards the open position (FIGS. 5A and 5B ), thecircumferential guide ridges 46 riding within theslots 79 act as camming surfaces thereby forcing the upper andlower portions guide ridges 46 and theguide groove 78 forces theupper sealing portion 16 in a direction away from thelower base portion 14, which remains stationary. When theupper sealing portion 16 is released and allowed to rotated towards a closed position, (FIGS. 6A and 6B ), the camming action between theguide ridges 46 and guidegrooves 78 forces the upper andlower portions guide grooves 78 and theguide ridges 46 may be reversed if desired. That is, theguide ridges 46 may be carried on the interiorcircumferential surface 82 of theupper sealing portion 16 and theguide groove 78 may be carried on thecircumferential wall 33 of thelower base portion 14. - As will be appreciated, during operation the elevation change of the upper sealing portion between the open and closed positions brings the sealing
lip 38 into contacting sealing relation with the interior of the upper sealing portion to facilitate a close sealed relation. In particular, it is contemplated that in the closed position, the second side 74 of theupper sealing portion 16 is placed into contacting sealing relation with the sealinglip 38 that bounds thelower dispensing opening 34. Thus sealed, the contents of thecontainer 12 are protected from the environment outside thecontainer 12, and vice versa. Conversely, when the lid is moved to the open position, the second side 74 of theupper sealing portion 16 is raised away from the sealinglip 38 without interference. - In order to promote the controlled opening of the lid assembly, the
lower base portion 14 may include anarcuate guide groove 44 in theupper surface 30. Thearcuate guide groove 44 is adapted to receive a guide post 60 (FIG. 4B ) that projects downwardly from theupper sealing portion 16. The guide post 60 rides in thearcuate guide groove 44 to maintain the lateral position of theupper sealing portion 16 with respect to thelower base portion 14 as the former is rotated to place thelid assembly 10 is an open or closed position. The length of thearcuate guide groove 44 may be dictated by the angle of rotation required to place thelid assembly 10 in an open position, and thus by the dimensions of thelower dispensing opening 34. By means of example and not limitation, as depicted inFIGS. 5A and 6A , the dimensions of thelower dispensing opening 34 are such that a like-dimensionedupper dispensing opening 66 located on theupper sealing portion 16 may be rotated through approximately 90° to fully expose the lower dispensing opening when in an open position, and to fully seal the same when in a closed position. If a narrowerlower dispensing opening 30 is utilized (along with a correspondingly narrower upper dispensing opening 66), a smaller minimum angle of rotation may be used to fully open and seal thelid assembly 10. The arcuate guide groove is preferably at least long enough to accommodate theguide post 60 through this angle of rotation. - The normal bias of the
lid assembly 10 to a sealed position is particularly beneficial in avoiding a situation in which thecontainer 12 is left open unintentionally. This sealing relation is potentially beneficial in packaging of a number of different materials that require sealed containment. By way of example only, in one contemplated environment of use, thecontainer 12 may be adapted to hold a continuous sheet of a plurality ofwipes 53, each individual wipe 53 being separated from an adjacent wipe by a line of perforation (FIGS. 5A and 5B ). As a wipe 53 is pulled through the dispensingaperture 52 having a star-like configuration, the relatively narrow opening imparts tension on the wipe. The tension imparted is such that after a line of perforation is pulled through the dispensingaperture 52, the adjacent wipes will tear along the line of perforation, thereby releasing a single wipe 53 for use, while retaining the formerly adjacent wipe within thecontainer 12 with a portion thereof extending through the dispensingaperture 52. - The dispensing
aperture 52 may also be adapted to efficiently and effectively dispense other materials held within the volume of thecontainer 12. By means of example and not limitation, the dispensingaperture 52 may consist of a plurality of openings, mesh, or grid, which may be effective for dispensing powders, granules, or other like particulate matter, or liquid matter from thecontainer 12 and through the dispensingaperture 52. As a further alternative, the dispensingaperture 48 may include a spout that may be contained within the volume of the cavity defining thelower dispensing opening 34. A spout would facilitate the pouring of liquids (as well as particulate matter) while minimizing spillage. It is further contemplated that thelower dispensing opening 34 may be entirely open, and not include the dispensingplate 49, thereby allowing a user to insert a scoop or like instrument through the lower dispensing opening and into the interior of thecontainer 12 in order to manually remove the material held therein. In another contemplated embodiment, the dispensingplate 49 may be removable and interchangeable with a plurality of dispensing plates, each bearing adifferent dispensing aperture 52. This modular design would permit a user to employ thelid assembly 10 of the present invention with containers for a number of different materials. - It is to be understood that while the present invention has been illustrated and described in relation to potentially preferred embodiments, constructions, and procedures, that such embodiments, constructions, and procedures are illustrative only and that the invention is in no event to be limited thereto. Rather, it is contemplated that modifications and variations embodying the principles of the invention will no doubt occur to those of ordinary skill in the art. It is therefore contemplated and intended that the present invention shall extend to all such modifications and variations as may incorporate the broad aspects of the invention within the true spirit and scope thereof.
