The present disclosure relates to container systems that include a squeeze-and-turn closure. The present disclosure also relates to closure systems that include a squeeze-and-turn closure. The present disclosure also relates to methods related to such systems.
Container systems that require a plurality of motions to open, for example push-and-turn or squeeze-and-turn, are known in the art and are often used to contain small items, such as medicines. However, such container systems are often not suitable for containing contents of a larger size or that require dispensation of larger volumes, e.g., articles to be grasped by an adult human hand or materials intended to be scooped. For example, the mouth of the container may not be sized appropriately to enable a human hand or scoop to fit through the opening.
The opening of the container, however, cannot simply be made larger. A larger opening requires a larger squeeze-and-turn closure, the size of which is constrained by the need to accommodate the span of an adult human hand. If the closure is too big, a user will not be able to squeeze the closure effectively. The desire to keep the opening small enough to accommodate a hand, however, can limit a manufacturer's ability to quickly and/or efficiently fill the container with contents.
Additionally, manufacturers face other difficulties. It can be expensive to manufacture a variety of closure systems to fit the spectrum of shapes and sizes of available containers. Therefore, it would be economical to manufacture one closure system or part thereof that is compatible with a variety of containers.
There is a need for improved container systems to meet one or more of the above challenges. It is desirable for the container systems and closure systems to be effective, intuitive to the user, and adaptable to the needs of manufacturers.
The present disclosure relates to container systems 100 and closure systems 150 that include a squeeze-and-turn closure 400.
The present disclosure also relates to container systems 100 that include: a container body 200 that has walls 210, 211, 212, 213, 214 defining an interior volume 202, and a rim 220 defining a container opening 222 that allows access to the interior volume 202, where the container opening 222 has a major axis 224 of a first length; a shroud 300 that is configured to be connectably engageable with the container body 200, the shroud 300 comprising a shroud opening 340 that allows access to the interior volume 202 through the container opening 222 when said shroud 300 is engaged with said container body 200, wherein said shroud opening 340 has a major axis 342 of a second length, said second length being less than said first length; and a closure 400 that is configured to be rotatably connectably engageable with said shroud 300 to close said shroud opening 340 when said closure 400 is engaged with said shroud 300 in a closed position, said closure 400 comprising a top wall 410, an outer skirt 420 depending downwardly from said top wall 410 toward said shroud 300 when said closure 400 is in said closed position, said outer skirt 420 comprising a first push pad 430, wherein when said closure 400 is in said closed position, said closure 400 is prevented from being rotated in an opening direction until said first push pad 430 is pressed radially inward.

The present disclosure also relates to a closure system 150 that includes: (a) a shroud 300 that is configured to be connectably engageable with a container body 200, said shroud 300 comprising a shroud opening 340 sized to be capable of receiving an adult human hand; and (b) a closure 400 that is configured to be rotatably connectably engageable with said shroud 300 to close said shroud opening 340 when said closure 400 is engaged with said shroud 300 in a closed position, said closure 400 comprising a top wall 410, an outer skirt 420 depending downwardly from said top wall 410 toward said shroud 300 when said closure 400 is in said closed position, said outer skirt 420 comprising a first push pad 430, wherein when said closure 400 is in said closed position, said closure 400 is prevented from being rotated in an opening direction until said first push pad 430 is pressed radially inward.
The present disclosure also relates to a container system 100 that includes: a container body 200 comprising bottom 210 and side walls 213, 214 defining an interior volume 202, a rim 220 defining a container opening 222 that allows access to said interior volume 202, wherein said container opening 222 is sized to be capable of receiving an adult human hand, and a first locking lug 350 and a second locking lug 360, said first and second locking lugs 350, 360 being located near the rim 314 and circumferentially spaced around a rotational axis RA; a closure 400 configured to be connectably engageable with said container body 200 to close said container opening 222 when said closure 400 is engaged with said container body 200 in a closed position, said closure 400 comprising a top wall 410, an outer skirt 420 depending downwardly from said top wall 410 toward said container body 200 when said closure 400 is in said closed position, said outer skirt 420 comprising a first push pad 430 and a second push pad 440 circumferentially spaced from said first push pad 430, a first locking tab 480 that engages said first locking lug 350 when said closure 400 in said closed position, a second locking tab 490 that engages said second locking lug 360 when said closure 400 in said closed position, wherein said engagement of said locking tabs 480, 490 with said locking lugs 350, 360 prevents rotation of said closure 400 in said opening direction, and wherein pressing said push pads 430, 440 radially inward causes said locking tabs 480, 490 to disengage from said locking lugs 350, 360, allowing said closure 400 to be rotated in said opening direction; and soluble unit dose articles 510, said articles comprising a water-soluble film that encapsulates a composition 500, preferably a household care composition, in at least one compartment.
The figures herein are illustrative in nature and are not intended to be limiting.
As described above, squeeze-and-turn closures must be small enough to be accommodating to a user's hand, but the resulting small opening makes filling the container efficiently a challenge, particularly when the contents are larger-sized articles.
The container systems 100 of the present disclosure solve this problem of finding balance by providing a three-piece container system. As seen in
The container systems 100 of the present disclosure also address this problem by providing a two-piece container system 100 that includes contents of a certain size. As seen in
In both cases, the closure 400 may be dimensioned to be easily operated by a user.
The present disclosure also relates to closure 400 systems that include a shroud 300 and a closure 400 as described herein, where the closure 400 system is adaptable to a variety of container bodies 200 having different sizes and/or shapes.
The present disclosure also relates to a container that comprises a container body 200 and a shroud 300, as each component is described herein.
It is further noted that squeeze-and-turn closures may be preferred over known hinged closures for a number of reasons. For example, squeeze-and-turn closures typically do not have hinges that flex 180° or more upon each opening; these hinges may wear out with repeated use. Furthermore, squeeze-and-turn closures, which require a plurality of motions to open, may be more secure against accidental opening; for example, if a container is dropped, a hinged lid may be more likely to pop open.
As used herein, the articles “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described. As used herein, the terms “include,” “includes,” and “including” are meant to be non-limiting. The systems, compositions, and methods of the present disclosure can comprise, consist essentially of, or consist of, the elements of the present disclosure.
The terms “substantially free of” or “substantially free from” may be used herein. This means that the indicated material is at the very minimum not deliberately added to the composition to form part of it, or, preferably, is not present at analytically detectable levels.

Container Systems
The present disclosure relates to container systems 100. As shown in
The container system 100 or any part thereof, may be formed utilizing any suitable materials. The container body 200 may be molded from a suitable plastic material such as polyethylene terephthalate. Any suitable polyolefins and/or polyesters may be used. The closure 400 and/or the shroud 300 or portions thereof may be formed partially or wholly of a moldable thermoplastic material, such as polypropylene, polyethylene, polystyrene, acrylonitryl butadiene styrene (ABS), polyester, polyvinyl chloride, polycarbonate or elastomer, or a blend of these materials. The closure 400 and/or shroud 300 may comprise polypropylene.
The container body 200 may be formed of a clear, transparent, or semi-transparent material, while the closure 400 may be formed of a substantially opaque material. The closure 400 may be translucent. The entire container system 100 (i.e, closure 400, shroud 300 if present, and container body 200) may be formed of substantially opaque materials. The closure 400 when formed of a substantially opaque material, can mask some of the empty volume at the top of the container body 200 when the container body 200 is formed of a clear material.
The materials used to form the container system 100 may have one or more colors. The container body 200, the closure 400, and the shroud 300 (if present) may all of the same color (e.g., all orange or all green). The container body 200 may be a different color than the closure 400 and/or the shroud 300 (if present) (e.g., white container body 200 and blue closure/shroud; or orange tub and silver closure/shroud). The colors may be selected to communicate the origin of the product (e.g., colors associated with the brand or manufacturer), the variant of the product (e.g., floral colors signaling particular perfume scents, or colors associated with a particular benefit or aspect of the contents, such as being free of dyes), or other signals as desired (e.g., seasonal or holiday colors).
The container systems 100, parts thereof, and methods of using such container systems are described in more detail below.
Closure
The present disclosure relates to closures 400, typically squeeze-and-turn closures. The closure 400 is configured to be rotatable around a rotation axis RA. The closure 400 can be rotated in a closing direction to a closed position. The closure 400 can be rotated in an opening direction that is counter to the closing direction to an open position. The closure 400 may be configured to be rotatably connectably engageable with a shroud 300 according to the present disclosure, where the closure 400 closes or seals the shroud opening 340 when the closure 400 is engaged with the shroud 300 in a closed position. See
As shown, for example, in
The closure 400 includes an outer skirt 420 depending downwardly from the top wall 410 in a direction that is toward the shroud 300 and/or container body 200 when the closure 400 is in a closed position. The outer skirt 420 may depend downwardly from the top wall 410 at an outer edge 413 of the top wall 410. The closure 400 may transition from the top wall 410 to the outer skirt 420 at a shoulder 419.
The outer skirt 420 may terminate at a lower edge 422 that is distal from the top wall 410. At least a portion of the outer skirt 420 is flexible to allow for the push pad(s) 430, 440 and locking tab(s) 480, 490 to be flexed as described herein.
The outer skirt 420 includes at least a first push pad 430. The push pad 430 is capable of being pressed radially inward, towards the rotation axis RA. The container system 100 is configured so that when the closure 400 is in a closed position, the closure 400 is prevented from being rotated in an opening direction until at least the first push pad 430 is pressed radially inward.
As can be seen in
The force required to flex the push pad 430, 440 may be adjusted by selecting panel and/or slot length, hinge placement, stiffening ribs, materials used, intentional areas of weakness (e.g., due to thinned areas, scoring, apertures, etc.), or other variables evident to one of ordinary skill. The pressing force required to disengage the locking tabs 480, 490 from the locking lugs 350, 360 is typically from about 1 pound to about 5 pounds, or from about 1.5 pounds to about 3 pounds.
The push pad 430, 440 may include irregularities 436, such as ribs, bumps, and/or dimples. Such irregularities 436 may provide friction and make the pad 430, 440 easier to grip when pressing the push pads 430, 440 and/or turning the closure 400.
As shown in
The first and second push pads 430, 440 may be circumferentially spaced apart by from about 45° to about 180°, preferably from about 90° to about 180°, more preferably about 180°. The first and second push pads 430, 440 may be diametrically opposed.
When viewed from the top and/or bottom, the closure 400 may be asymmetrical. Having an asymmetrical closure (i.e., where one axis is greater than another) may be useful for a number of reasons. For example, when the closure 400 is not in a properly closed position, the misalignment of an asymmetric closure 400 with the shroud 300 and/or container body 200 can provide a visual signal to alert the user or manufacturer. Additionally, an asymmetric closure 400 may conform better to an asymmetric container body 200, for example one that is wider than it is deep, which may provide maximum shelf impression.
As shown in
The closure 400 may have an upper periphery 414 about the outer edge 413 of the top wall 410. The closure 400 may have a lower periphery 423 about the lower edge 422 of the outer skirt 420, ignoring any gaps or slots in the lower edge 422. The lower periphery may have a major axis 424 and a minor axis 425. The lower periphery 423 may be larger than the upper periphery 414, such as when the outer skirt 420 extends downwardly from the top wall 410 and radially outward. This configuration may be preferred to provide a more unitary look to the container system 100; for example, the slope of the outer skirt 420 could substantially match the slope on a part of the shroud 300 and/or container body 200. The outer skirt 420 may extend axially downwardly and not radially outward (i.e., substantially straight downwardly), so that the lower periphery 423 may be approximately the same size as the upper periphery 414. The outer skirt 420 may even extend downwardly and radially inward, so that the lower periphery 423 may be smaller than the upper periphery 414. This configuration may be preferred to increase the security of the closure 400, as the pressing pads 430, 440 may be more challenging to depress, or to increase the grippability of the closure 400, as the top wall 410 may fit more securely in the palm of the user's hand as the user's fingers curl down the side.
The closure 400 may include indicia 450. The indicia 450 may be located on the top wall 410, including the outer surface of the top wall 410. The indicia 450 may be molded integrally with, printed on, and/or affixed (such as by label or sticker) to the closure 400. The indicia 450 may comprise text, a graphic, or a combination thereof. The indicia 450 may indicate: the origin of the container system 100 or closure system 150; the manufacturer of the container system 100 or closure system 150; an advertising, sponsorship, or affiliation image; a trademark or brand name; a safety indication; an instructional indication; a product use or function indication; a sporting image; a geographical indication; an industry standard; preferred orientation indication; an image linked to a perfume or fragrance; a charity or charitable indication; an indication of seasonal, national, regional or religious celebration, in particular spring, summer, autumn, winter, Christmas, New Years; or any combination thereof. Further examples include random patterns of any type including lines, circles, squares, stars, moons, yin yang symbols, flowers, animals, snowflakes, leaves, feathers, sea shells, and Easter eggs, among other possible designs. The indicia 450 may indicate a safety indication, an instructional indication, a trademark or brand name, or combinations thereof. The instructional indication may indicate how to open the container system 100, for example with arrows indicating the direction to depress the moveable panels and/or arrows showing the direction of rotation required to open the container system 100. The shroud 300 and/or container body 200 may comprise, for example on the shoulder 320, any of the indicia 450 described above.
Because the closures 400 of the present disclosure may be used for container systems 100 that require openings large enough to fit a human hand, the closures 400 may be wider than they are tall. This configuration can allow a user's fingers to span across the relatively wide opening while still being able to reach and operate the push pads 430, 440 of the outer skirt 420.
As seen in
As shown in
The closure 400 may have a span length 427. As used herein, “span length” 427 of the closure 400 is measured from the middle of one push pad (W), to the outer edge of the top wall (X), across the top wall to the opposite outer edge (Y), to the middle of the opposite push pad (Z). In
As shown in
The closure 400 may include an inner skirt 470 that depends downwardly from the inner surface 412 of the top wall 410. The inner skirt 470 may be positioned radially inward to the outer skirt 420. The inner skirt 470 may intersect with the outer skirt 420 at one or more intersection points 472, 473. The inner skirt 470 may comprise the connecting feature 460, such as one or more threads 462, typically on an inner surface 474 of the inner skirt. The inner surface 474 may be continuous, as shown in
The connecting feature 460 of the closure 400 (e.g., threads) and the complimentary connecting feature 330 on the shroud 300 and/or container body 200 may be configured to allow the closure 400 to be removable from the shroud 300 and/or container body 200 upon relatively rotating the closure 400 from the closed position in an opening direction by not more than about 180°, preferably by not more than about 135°, more preferably by not more than about 90°. This provides the effect of the closure 400 being removeable after a half-turn, or even a quarter-turn, in the opening direction. Such a configuration can allow a user to open the container system 100 with one hand without having to release the closure 400 and reset the hand position for a second turn, allowing for quick and convenient access.
As seen in
The closure 400 may comprise more than one locking tab 480, 490. The number of locking tabs 480, 490 may be equal to the number of push pads 430, 440.
The closure 400 may comprise a second locking tab 490. The outer skirt 420 may comprise the second locking tab 490. The second locking tab 490 may be configured to engage a second locking lug 360 on the shroud 300 or container body 200 when the closure is in the closed position to prevent rotation of the closure 400 in the opening direction. Pushing the second push pad 440 radially inward may cause the second locking tab 490 to disengage with the second locking lug 360, and the closure 400 may then be able to be rotated in an opening direction while the second push pad 440 is being pressed, typically simultaneously as when the first push pad 430 is being pressed.
As shown in the closures 400 of
The locking tab 432, 442 may have a tab leading face 482, 492 that leads when the closure 400 is rotated in a closing direction. The tab leading face 482, 492 may be rounded or angled, which can help to facilitate the deflection of the locking tab 480, 490 upon rotation in a closing direction as it encounters the locking lug 350, 360. The tab leading face 482, 492 may be the narrowest part of the locking tab 480, 490, which can also help to facilitate the deflection of the locking tab 480, 490 upon rotation in a closing direction as it encounters the locking lug 350, 360. The tab leading face 482, 492 may be configured to deflect the locking tab 480, 490 radially outward or radially inward when the locking tab 480, 490 encounters the locking lug 350, 360, which is typically stationary, upon closing.
The locking tab 480, 490 may have an inner surface 484, 494 that faces radially inward. The locking tab 480490 may have an outer surface 485, 495 that faces radially outward. The inner and/or outer surfaces may be flat, or one or both surfaces may have a slight curve, for example, to match the arc of a circumference of a circle at the particular radius at which the surface can be found.
The locking tab 480, 490 may have a tab locking face 486, 496 opposite the tab leading face 482, 492. The tab locking face 486, 496 may engage the locking lug 350, 360 when the closure 400 is in a closed position to prevent rotation in the opening direction. The tab locking face 486, 496 may be relatively flat to maximize contact with the locking lug 350, 360. In the radial direction, the tab locking face 486, 496 may be the widest part of the locking tab 480, 490.
As shown in
While it may be desirable for at least the push pads 430, 440 to be depressible, such flexibility may not be desired at other points of the closure 400, or even at other points of the outer skirt 420. Thus, the closure 400 may include support walls 428, which may help to increase rigidity at least at certain points of the closure 400. For example, the support walls 428 may extend between the outer skirt 420 and the inner skirt. The support walls 428 may extend in a substantially radial direction. The support walls 428 may be spaced apart from the pressing pads 430, 440.
As seen in
In the closure 400 of
The closure 400 of
The closure 400 may be configured so that when the push pad 430, 440 is pressed radially inward, the locking tab 480, 490 flexes radially outward. For example, the closure 400 of
The locking tabs 480, 490 may be circumferentially spaced away from the push pads 430, 440. For example, the closure 400 of
The closure 400 may comprise a water-sealing structure. This is particularly preferred when it is anticipated that the contents of the container system 100 are water-sensitive, e.g., articles that degrade or dissolve in the presence of water in liquid and/or vapor form. The water-sealing structure may be a plug seal, a gasket seal, or a combination thereof. The container system 100 may comprise a hygroscopic material, e.g., a desiccant.
When the closure 400 is in the closed position, the container system 100 may have a MVTR measurement of less than about 2.0 grams per day per square meter of package surface (g/day/m{circumflex over ( )}2), or less than about 1.0 g/day/m{circumflex over ( )}2, or less than about 0.75 g/day/m{circumflex over ( )}2, or less than about 0.50 g/day/m{circumflex over ( )}2, or less than about 0.25 g/day/m{circumflex over ( )}2, at 35° C. and 65% relative humidity. MVTR is determined according to ASTM D7709.
The closure 400 may comprise one or more stacking features to facilitate the stacking of closure systems 150, or container systems 100 on top of one another. The stacking feature may be configured to be received by the closure 400, the closure systems 150, or the container systems 100 that are stacked on top of it. For example, the stacking feature may be configured to extend into the opening 340 of the shroud 300, to nest inside the inner skirt 470 of the closure 400, and/or to engage with the bottom wall 210 of the container body 200, e.g., by encircling or nesting within the bottom wall 210 when container body 200 is stacked on top of the closure 400. The one or more stacking features may be one or more ridges that project axially away from the outer surface of the top wall 410. The stacking features may be continuous or intermittent. The stacking features may be located at or near the outer edge of the top wall 410. The stacking features may have a shape that is complimentary to the shape defined by the top wall outer edge 413, or the stacking structures may have a different shape.
Even when the closure 400 is disengaged or detached from opening of the shroud 300 or container body 200 so that the container system 100 is in an open position, the closure 400 may still be attached to the shroud 300 or container body 200. For example, the closure 400 may be attached to the shroud 300 or container body 200 by a hinge, or by a hinged piece that allows rotation of the closure 400. The closure 400 may be attached to the shroud 300 or container body 200 by a retaining structure, such as a strap, having a first end attached to the shroud 300 or container and a second end attached to the closure 400. Such features may be useful to prevent closure 400 becoming separated or lost from the rest of the container system 100.
Shroud
The container systems 100 of the present disclosure may include a shroud 300. The shroud 300 may be configured to be an intermediate or transition piece between the closure 400 and the container body 200. As described above, an advantage of a shroud 300 in the present container systems 100 is that the opening to the container body 200 can be large to facilitate filling, while the opening onto which the closure 400 connects can be relatively smaller, so that the closure 400 can conveniently be operated with one hand. Other advantages include the flexibility to use the same closure 400 and shroud 300 with container bodies of different sizes and/or shapes. Use of a shroud 300 or a plurality thereof also allows the same closure 400 to be used with shrouds 300, 301 of different sizes and/or shapes, providing the manufacturer with a greater degree of flexibility and cost-savings. Compare, for example,
The shroud 300 may be configured to be connectably engageable with the container body 200 and, separately, to the closure 400.
As shown in
The neck 310 may terminate in a rim 314, which may define the shroud opening 340. The shroud opening 340 allows access to the interior volume 202 of the container body 200 through the container opening 222 when the shroud 300 is engaged with the container body 200.
The shroud opening 340 may be sized to allow an adult human hand to pass through to access the contents contained in the interior volume 202 of the container body 200. The shroud opening 340 may have a major axis 342 of a second length, as measured from the inner surface 312 of the neck 310 on one side of the neck 310 to the inner surface 312 on the opposite side. The shroud opening 340 may have a major axis 342 having a second length of from about 60 mm to about 150 mm, or from about 75 mm to about 120 mm, or from about 80 mm to about 100 mm, or from about 85 mm to about 90 mm. The shroud opening 340 may substantially circular, and the major axis 342 may be a diameter.
The shroud opening 340 may be smaller than the opening 222 of the container body 200. The second length may be less than the first length (i.e., the length of the major axis 224 of the container opening 222). A plane defined by the rim 220 of the container opening 222 may have a greater surface area than that of a plane defined by the rim 314 of the neck 310.
The shoulder of the shroud 300 may comprise an outer surface 322, which faces away from the container body 200 when the shroud 300 is engaged with the container body 200. The shoulder may further comprise an inner surface 323 oppositionally positioned to the outer surface 322, where the inner surface 323 faces towards the container body 200 when the shroud 300 is engaged with the container body 200.
The shoulder 320 of the shroud 300 may comprise an upper shoulder 324 and a lower shoulder 426. The upper shoulder 324 may extend peripherally from the neck 310 of the shroud 300. The upper shoulder 324 may be defined by a generally flat annular surface, which may be concentric with the center of the shroud opening 340. The upper shoulder 324 may substantially horizontal to the top wall 410 of the closure 400 when the closure 400 is in a closed position on the shroud 300. The upper shoulder 324 may have an outer periphery 325, which defines where the upper shoulder 324 meets, and is adjacent to, the lower shoulder 326. The outer periphery 325 may be configured to be substantially flush with the outer skirt 420 of the closure 400 when the closure 400 is in the closed position, which may provide a pleasing overall appearance due to the continuous character of the closure 400 and shroud 300.
The shroud 300 may comprise at least a first locking lug 350. The shroud 300 may comprise a second locking lug 360. The locking lugs 350, 360 may be located on the shoulder 320, typically the upper shoulder 324, of the shroud 300. The locking lugs 350, 360 may project axially upwardly from the outer surface 322 of the shoulder 320. The locking lug 350, 360 may be configured and positioned to engage the locking tab 480, 490 of the closure 400 when the closure 400 is in the closed position so that rotation of the closure 400 in an opening direction is prevented until at least one pressing pad 330, 340 on the closure 400 is pressed. In an opening or closing operation, the locking lugs of the shroud 300 are typically stationary.
The locking lugs 350, 360 may located on a radius that is substantially parallel to the major dimension 204 of the container.
The locking lugs 350, 360 may be found in other positions as well. For example, the locking lugs 350, 360 may project radially outward from the neck 310. As shown in
Each locking lug 350, 360 may include a locking face 352, 362, typically extending substantially along a radius of the shroud opening 340. The locking face 352, 362 of the shroud's locking lug 350, 360 may be configured to engage the tab locking face 486, 496 of the closure's locking tab 480, 490 and prevent rotation in the opening direction.
Each locking lug 350, 360 may include an outer surface 354, 364 positioned to face radially outwards from the neck 310. The outer surface 354, 364 of the lug 350, 360 may be flat, or it may be shaped in the form of a circular arc with a centerpoint corresponding to the center of the shroud opening 340.
Each locking lug 350, 360 may include an inner surface 356, 366 positioned to face radially inward towards the neck 310. At least a portion of the inner surface 356, 366 may be formed perpendicular to the locking face 352, 362. At least a portion of the inner surface 356, 366 may be angled to help to ensure that the locking tabs 480, 490 of the closure 400 will be deflected radially inward as they move past the locking lugs 350, 360 as the closure 400 is rotated in the closing direction. The inner surface 356, 366 may be formed on a parting line of the mold used to make the shroud 300.
The locking lug 350, 360 may be configured so that the locking tabs 480, 490 of the closure 400 will be deflected radially outward as the tabs 480, 490 move past the locking lugs 350, 360 as the closure 400 is rotated in a closing direction. The outer surface 354, 364 of the locking lug 350, 360 may be angled to facilitate the deflection.
To close the container system 100, whether the locking lugs 350, 360 are on the shroud 300 or on the container body 200, the closure 400 may be relatively rotated on the neck 310 in a closing direction, where the connecting feature 460 (e.g., threads 462) of the closure 400 engages and mates with the complimentary connecting feature 330 (e.g., thread grooves) of the shroud neck 310 or container body 200. As the closure 400 continues to rotate, the tab leading face 482, 492 of the closure 400 may contact the locking lugs 350, 360. Further rotation of the closure 400 results in the locking tab 480, 490 deflecting around the locking lug 350, 360 until the tab 480, 490 passes the lug 350, 360, at which point the tab 480, 490 may return or even snap back to its original (undeflected) position. At this point, the locking face 486, 496 of the locking tab 480, 490 may be engaged with the locking face 352, 362 of the locking lug 350, 360, and rotation in an opening direction is prevented until the push pads 430, 440 are pressed.
The closure 400 and/or shroud 300 may be configured so that when the locking tab 480, 490 returns to its original position, an audible signal such as a click is produced. An audible signal may be useful for communicating to the user that the container system 100 is closed and secure.
When the locking tab 480, 490 of the closure 400 is located radially inward to the push pad 430, 440, as shown in
To disengage the closure 400 from the shroud 300, whether the locking lugs are on the shroud 300 or the container body 200, a user can place a finger, for example, on each pressing pad 430, 440, preferably with one hand, and press radially inward. When the pressing pads 430, 440 are pressed, the locking tabs 480, 490 may be radially displaced (either radially inward or outward, depending on the configuration of the closure 400) and disengage with the locking lugs 350, 360. When the closure 400 is relatively rotated in an opening direction with the push pads 430, 440 pressed, the locking tabs 480, 490 can slide past the locking lugs 350, 360. Once locking tabs 480, 490 are disengaged from the locking lugs 350, 360 and begin to slide past them, the push pads 430, 440 may no longer need to be depressed, and the closure 400 can be unscrewed in a known manner.
As shown in
The shroud 300 may be connectably engageable with a container body 200. As shown in
The body-connecting feature 370 may be located on an inner skirt 374 of the shroud 300. The inner skirt 374 may depend axially downwardly from the inner surface 312 of the shroud 300. The inner skirt 374 may be substantially concentric with the opening 340, although it need not have the same general shape. The body-connecting feature 370 may project radially inward from an inner surface of the inner skirt 374. The body-connecting feature 370 may be continuous around the inner skirt 374, or it may be discontinuous. The body-connecting feature 370 may comprise a plurality of segments, such as two, three, or four segments. The segments may be located to correspond to certain walls or certain corners adjacent the opening 222 of the container body 200.

The interior volume 202 may have a volume no more than about 100 L, or no more than about 50 L, or no more than about 10 L, or no more than about 8 L, or no more than about 6 L, or no more than about 5 L, or no more than about 4 L, or no more than about 2 L, or no more than about 1 L.
The container body 200 may include a rim 220 at an upper portion of the container body 200. The rim 220 may define a container opening 222. The container opening 222 allows access the interior volume 202.
As shown in
The container body 200 may include a shroud-connecting feature 232, which may facilitate connection of the container body 200 to the shroud 300. The shroud-connecting feature 232 may be located on the container neck 230, for example on an outer surface of the container neck 230. The shroud-connecting feature 232 may comprise a thread, a thread groove, a rib 233, or a bead. The shroud-connecting feature 232 may be configured to complimentarily mate with the body-connecting feature 370 of the shroud 300 so that the shroud 300 is securely fastened to the container body 200. The opening 222 of the container body 200 is typically axially aligned with the shroud opening 340 when the shroud 300 is connected to the container body 200.
The container body 200 may include handle portions 217, 218. The handle portions 217, 218 may be molded as part of the walls 212, 213, 214. Such handle portions 217, 218 are useful for picking up the container 200 or holding it with one hand while the other hand is used to rotate the closure 400. The container body 200 may include two handle portions 217, 218.
The container body 200 may include a groove configured to receive the lower edge of the shroud 300. Such a groove can improve the security of the container systems 100, 101 as the shroud 300/closure system 150 are more challenging to be pried off in an unintended manner.
As shown in
The closure's top wall 410 may have a major axis 415, for example line X-Y in
The container 200 may have a major horizontal dimension 204, extending from one wall to an opposite wall in the horizontal plane when standing upright. The container may have a minor horizontal dimension 206, extending from one wall to an opposite wall in the horizontal plane when standing upright. The major dimension 204 is typically greater than the minor dimension 206. In the container shown in
The container opening 222 may be substantially circular, in which case the major axis of the container opening 222 may be a diameter.
The container opening 222 may be non-circular. The container opening 222 may have a minor axis 206 of a third length. The third length may be from about from about 70 mm to about 120 mm, or from about 80 mm to about 100 mm, or about 90 mm. The third length may be less than the first length, greater than second length, or both. The first length may be at least 10% greater than the third length. The ratio of the first length to the third length may be from about 2:1 to about 1:1, or about 4:3.
The closure's lower periphery major axis 424 or the major axis 415 of the top wall 410 of the closure 400 (fourth length) may be greater than the minor axis 225 of the container opening 222 (third length). When either major axis 415, 424 of the closure 400 has a greater length than the minor axis 225 of the container opening 222, it may be easier to see when the closure 400 is not in a closed position due to misalignment.
The first length and/or third length may be at least two times, or at least three times, or at least four times greater than the width of an article 510 contained in the interior volume 202 of the container body 200. Typically, the greater the ratio of the major and/or minor axis 224, 225 to the size of the article 510, the more efficiently the container body 200 can be filled with the articles. The first length and/or third length may be up to twenty times, or up to fifteen times, or up to ten times greater than the width of an article contained in the interior volume 202 of the container body 200.
