Title: Squeezable closures

Description:
FIELD OF THE INVENTION 
     The present disclosure relates to squeezable closures. The present disclosure further relates to container systems, closure systems, and methods that include such closures. 
     BACKGROUND OF THE INVENTION 
     Squeezable closures, such a squeeze-and-turn closures, are generally known as a method of increasing the security of container systems. These closures often have an inner skirt used to connect the closure to a container and an outer skirt that can be squeezed to enable the closure to be removable from the container. As seen in  FIG. 1 , which shows a closure  800  of the prior art, the inner skirt  810  and outer skirt  820  are typically concentric circles. However, due to the double skirt configuration, they tend to have a relatively large footprint. This may be particularly undesirable for use with certain containers that have one horizontal dimension that is greater than another; for example, a container may be wider (side-to-side) than it is deep (front-to-back). While such containers can allow for a greater shelf impression in a retail environment, the closures may be larger than necessary and may detrimentally impact how tightly the containers may be packed together and/or detract from the aesthetics of the container system. 
     To reduce the footprint of such squeezable closures in at least one dimension (such as in the front-to-back dimension), some manufacturers have replaced the continuous inner skirt with separate hanging walls  830 ,  831  that are radially interior to the outer wall  820 , as shown in  FIG. 2 , which shows another closure  801  of the prior art. The hanging walls  830 ,  831  can provide a connection to the container, for example by screwing onto a neck of the container, but challenges remain due to the lack of a continuous inner skirt. Because the closure is connected to the container only at several smaller discrete points rather than a larger continuous connection, the closure may not stay tight to the bottle; for instance, the closure may be relatively susceptible to being pried off, resulting in accidental or unintentional opening. Additionally, robust and/or repeated squeezing of the closure may deform the closure so that the hanging walls do not connect as tightly to the container over time. 
     There is a need for improved squeezable closures that are secure while providing a reduced footprint. 
     SUMMARY OF THE INVENTION 
     The present disclosure relates to squeezable closures  400 . 
     The present disclosure also relates to closures  400  that include: a top wall  410 ; an inner skirt  470  depending from said top wall  410 , said inner skirt  470  comprising connecting features configured to allow for selective connectable engagement with a container  200 ; an outer skirt  420  depending from said top wall  410  and located radially outward from said inner skirt  470 , said outer skirt  420  comprising at least a first push pad  430  and at least a first locking tab  480 , wherein pressing said first push pad  430  radially inward causes said first locking tab  480  to move from a first position to a second position; wherein said inner skirt  470  and said outer skirt  420  are connected at at least a first intersection point  472  that is circumferentially spaced from said first push pad  430 .

     DETAILED DESCRIPTION OF THE INVENTION 
     The present disclosure relates to a squeezable closure  400  that provides desirable relative dimensions while remaining robust and secure. In short, the closures  400  of the present disclosure include a continuous inner skirt  470  for connection to a container  200  and an outer skirt  420  that includes at least one push pad that must be engaged to remove the closure  400  from a container  200 . The inner skirt  470  and the outer skirt  420  intersect at at least one intersection point, preferably two intersection points  472 ,  473 , this is circumferentially spaced from the push pad. Without wishing to be bound by theory, it is believed that the continuous inner skirt  470  provides a secure closure mechanism, while the intersection point provides increased structural support to the closure  400  and allows for a lesser dimension than fully concentric (and non-intersecting) skirts would provide. 
     The closures  400  and related container systems  100 , closure systems  150 , and methods are discussed in more detail below.

     Closure 
     The present disclosure relates to closures  400 , particularly squeezable closures. The closures  400  of the present disclosure may include: a top wall  410 ; an inner skirt  470  depending from said top wall  410 , said inner skirt  470  comprising connecting features  460  configured to allow for selective connectable engagement with a container  200 ; an outer skirt  420  depending from said top wall  410  and located radially outward from said inner skirt  470 , said outer skirt  420  comprising at least a first push pad  430  and at least a first locking tab  480 , wherein pressing said first push pad  430  radially inward causes said first locking tab  480  to move from a first position to a second position; wherein said inner skirt  470  and said outer skirt  420  are connected at at least a first intersection point  472  that is circumferentially spaced from said first push pad  430 . These elements are discussed in more detail below. 
     The squeezable closure  400  may be a squeeze-and-turn closure. As shown in  FIG. 3 , the closure  400  may be 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. The closure  400  may be configured to be rotatably connectably engageable with a container  200  according to the present disclosure, where the closure  400  closes or seals the container opening  222  when the closure  400  is engaged with the container  200  in a closed position. 
     As shown, for example, in  FIGS. 3-7 , the closure  400  includes a top wall  410 . The top wall  410  may have an outer surface  411  and an inner surface  412 . The outer surface  411  faces away from the shroud  300  and/or the container body  250  when the closure  400  is in a closed position. The inner surface  412  faces the shroud  300  and/or container body  250  when the closure  400  is in a closed position. 
     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  FIGS. 3-5 , the push pad  430 ,  440  may comprise a panel  432 ,  442 . The panel  432 ,  442  may be formed by at least one slot  434 ,  444  in the outer skirt  420 , preferably two slots  434 ,  435 ,  444 ,  445 . The slots  434 ,  435 ,  444 ,  445  may be longitudinal slots extending from a lower edge of the outer skirt  420  toward the top wall  410 . The slots  434 ,  435 ,  444 ,  445  may extend a fraction of the outer skirt  420 , or they may extend to or near to the outer edge  413  of the top wall  410 . Slots  434 ,  435 ,  444 ,  445  may make the push pad  430 ,  440  easier to depress, as only a portion of the outer skirt  420  needs to be deformed in order to open the closure  400 . Such a configuration may be particularly suitable for those with weak grip strength, such as the elderly. 
     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  FIG. 5 , the closure  400  may include a first push pad  430  and a second push pad  440 . Each push pad  430 ,  440  may comprise a panel  432 ,  442  formed from slots  434 ,  435 ,  444 ,  445 . The container system  100  may be configured so that the closure  400  is prevented from being rotated in an opening direction until the second push pad  440  is pressed radially inward, preferably at the same time as when the first push pad  430  is pressed radially inward. Two or more push pads  430 ,  440  may be preferred to increase the security of the container system  100 , as a more complex action is required to open the closure  400 . 
     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 lid (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 with the shroud  300  and/or container body  250  can provide a visual signal to alert the user or manufacturer. Additionally, an asymmetric closure may conform better to an asymmetric container body  250 , for example one that is wider than it is deep, which may provide maximum shelf impression. 
     As shown in  FIG. 5 , when viewed from the top, the top wall  410  of the closure  400  may include a major axis  415 , measured from one side of the outer edge  413  of the top wall  410  to the opposite side along a major dimension. See also line X-Y of  FIG. 3 . The top wall  410  of the closure  400  may include a minor axis  416 , measured from one side of the outer edge  413  to an opposite side. At least one or both of the axes  415 ,  416  may be selected and configured to be smaller than the span of the average adult human hand, so that the closure  400  can be operated with one hand. The length of the major axis  415  may be greater than the length of the minor axis  416 . The major axis  415  may have a length of from about 70 mm to 130 mm, or from about 80 mm to about 120 mm, or from about 90 mm to about 110 mm, or from about 95 mm to about 105 mm, or about 100 mm. The minor axis  416  may have a length of from about 50 mm to about 120 mm, or from about 70 mm to about 110 mm, or from about 80 mm to about 100 mm, or about 90 mm. The ratio of the major axis  415  to the minor axis  416  may be from about 2:1, or from about 1.5:1, or from about 1.3:1, or from about 1.2:1, or from about 1.15:1, to about 1:1. 
     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 in the lower edge. The lower periphery  423  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  250 . 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&#39;s hand as the user&#39;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  411  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  432 ,  442  and/or arrows showing the direction of rotation required to open the container system  100 . The shroud  300  and/or container body  250  may comprise, for example on the shoulder, 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&#39;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 shown in  FIG. 6 , the closure  400  may have a height  452 , measured from a horizontal plane extending from the lower edge  422  of the outer skirt  420  to a parallel horizontal plane extending from the top wall&#39;s outer surface  411 . The closure height  452  may be from about 5 mm to about 50 mm, or from 7 mm to about 30 mm, or from about 8 mm to about 25 mm, or from about 10 mm to about 20 mm. The ratio of closure height  452  to the major axis  415  of the closure&#39;s top wall  410  may be from about 10:1 to about 1:15, or from about 5:1 to about 1:12, or from about 1:1 to about 1:10, or from about 1:5 to about 1:10, or from about 1:8 to about 1:10. The height 452 of the closure 400 may be at least 50% less, preferably at least 75% less, than the length of the major axis of the closure&#39;s top wall  410 . The ratio of closure height  452  to the major axis  415  of the closure&#39;s top wall  410  may be selected to fit the maximum functional hand span of an adult hand while still allowing fingers to depress the panels  432 ,  442 . 
     As shown in  FIG. 6 , the outer skirt  420  may have an outer skirt length  426 , measured as the distance from the lower edge of the skirt  422  to the outer edge  413  of the top wall  410 . The skirt length  426  may be at least 50% less, preferably at least 75% less, than the length of the major axis  415  of the closure&#39;s top wall  410 . If the outer skirt  420  is not substantially orthogonal to the top wall  410 , the skirt length may be greater than the height of the closure  400 . 
     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  FIG. 6 , the span length  427  is equivalent to total length of the line that is drawn from point W to point X to point Y to point Z (or “line W-X-Y-Z”). The span length  427  may be selected to fit the maximum functional hand span (or pinch grip) of an average adult human hand. The span length  427  may be adjusted depending on the target population of container system users; for example, females tend to have shorter hand spans than males. The span length  427  may be from about 50 mm, or from about 70 mm, or from about 90 mm, or from about 105 mm, to about 150 mm, or to about 130 mm, or to about 120 mm, or to about 115 mm or to about 110 mm. 
     As shown in  FIGS. 7 and 8 , the closure  400  includes an inner skirt  470  that depends downwardly from the inner surface  412  of the top wall  410 . The inner skirt  470  is positioned radially inward to the outer skirt  420 . The inner skirt  470  comprises an inner surface  474  facing radially inward and an outer surface  478  facing radially outward. The inner surface  474  is typically continuous circumferentially, for at least the part of the inner skirt  470  that that connects to the container  200 . The inner skirt  470  may terminate in a lower edge that is distal from the top wall  410 . 
     The inner skirt  470  intersects with the outer skirt  420  at one or more intersection points  472 ,  473 . The lower edge of the inner skirt  470  may intersect with the lower edge of the outer skirt  420  at the one or more intersection points  472 ,  473 . 
     The outer skirt  420  and inner skirt  470  may intersect at a first intersection point  472 . The first intersection point  472  may be circumferentially spaced from the first push pad  430 . The first intersection point  472  may be circumferentially spaced by from about 45° to about 135°, or from about 60° to about 120°, or about 90°, from the first push pad  430  and/or the second push pad  440 . 
     The inner skirt  470  and the outer skirt  420  may be additionally connected at at least a second intersection point  473 . The second intersection point  473  may be circumferentially spaced from the first push pad  430 . The second intersection point  473  may be circumferentially spaced by from about 45° to about 135°, or from about 60° to about 120°, or about 90°, from the first push pad  430  and/or the second push pad  440 . 
     The second intersection point  473  may be circumferentially spaced from the first intersection point  472 . The first intersection point  472  may be diametrically opposed to the second intersection point  473 . 
     The first intersection point  472  may be circumferentially spaced between first and second push pads  430 ,  440 . The second intersection point  473  may be circumferentially spaced between first and second push pads  430 ,  440 . 
     The first intersection point  472  may be located along the minor axis  416  of the top wall  410  of the closure  400 . The first and second intersection points  472 ,  473  may be located along the minor axis  416  of the top wall  410  of the closure  400 . This may be particularly preferred when the first push pad  430  is, or the first and second push pads  430 ,  440  are, located along the major axis  415  of the top wall  410  of the closure  400 . 
     At the intersection point(s), the inner skirt  470  and the outer skirt  420  may merge and appear as a single wall. The intersection points  472 ,  473  may be symmetrical. 
     The intersection points  472 ,  473  may be located adjacent an inner periphery  475  of the inner skirt  470 , wherein the inner surface  474  of the inner skirt  470  meets the inner surface  412  of the top wall. The inner periphery  475  may be a circle. The intersection point may not be a single Euclidean point, but may instead trace a portion of the periphery  475  of the inner skirt  470 . One or more of the intersection points  472 ,  473 , or each intersection point, may independently trace a portion of the inner periphery  475  of the inner skirt  470  that is at least about 1%, or at least about 3%, or at least about 5%, or at least about 10%, of the periphery  475  of the inner skirt  470 . One or more of the intersection points  472 ,  473 , preferably each intersection point, may be an arc of the periphery  475 . The arc may subtend an angle (θ) of at least about 1°, or at least about 3°, or at least about 5°, or at least about 10°, or at least about 15°, or at least about 20°, or at least about 30°, or at least about 40°, as measured from a center point of the inner skirt  470 , typically on a rotational axis RA. It is believed that the larger the intersection point, the more stability will be provided. 
     One or more of the intersection points  472 ,  473 , or each intersection point, may trace a portion of the periphery  475  of the inner skirt  470  that is no greater than about 40%, or not great than about 35%, or no greater than about 30%, or no greater than about 25%, or no greater than about 20%, or no greater than about 15% of the periphery of the inner skirt  470 . One or more of the intersection points  472 ,  473 , preferably each intersection point, may be an arc of the periphery  475  of the inner skirt  470 . The arc may subtend an angle (θ) of no more than about 90°, or no more than about 75°, or no more than about 60°, or no more than about 50°, as measured from a center point of the inner skirt  470 , typically on a rotational axis RA. It is believed that if the intersection point is too large, then the push pads  430 ,  440  will be relatively challenging to press. The angle may be from about 40° to about 45°, or about 42°. 
     The closure  400  includes a connecting feature  460  capable of engaging with a complimentary connecting feature  330  on the shroud  300  and/or container body  250 . The connecting feature  460  may include at least one thread  462 , or at least two threads. The connecting feature  460  may include lugs that are received by receiving notches when the closure  400  is rotated in a closing direction. 
     The inner skirt  470  may comprise the connecting feature  460 , such as one or more threads  462 , typically on the inner surface  474  of the inner skirt  470 . 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  250  may be configured to allow the closure  400  to be removable from the shroud  300  and/or container body  250  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. 
     The connecting feature  460  on the closure  400  and the complimentary connecting feature  330  on the shroud  300  and/or container body  250  may be configured so that when the closure  400  is in the closed position, a radius  454  drawn through one or more intersection points  472 ,  473  of the closure  400  is substantially parallel to a minor dimension  206  of the container  200 . The connecting feature  460  and the complimentary connecting feature  330  on the shroud  300  and/or container body  250  may be configured so that when the closure  400  is in the closed position, the intersection point is oriented towards the front or rear of the container  200 . When there are at least two intersection points  472 ,  473 , the first intersection point  472  may be oriented towards the front of the container  200  and the second intersection point  473  may be oriented towards the rear of the container  200 . 
     As shown in  FIGS. 7 and 8 , the closure  400  comprises at least a first locking tab  480 . The outer skirt  420  may comprise the first locking tab  480 . The first locking tab  480  is configured to engage a first locking lug  350  located on the shroud  300  or container body  200  when the closure  400  is in the closed position to prevent rotation of the closure  400  in the opening direction. Pushing the first push pad  430  radially inward causes the first locking tab  480  to disengage with the first locking lug  350 , and the closure  400  may then be able to be rotated in an opening direction while the first push pad  430  is being pressed. 
     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  FIGS. 7 and 8 , the locking tabs  480 ,  490  may be in substantially radial alignment with the push pads  430 ,  440 . The locking tabs  480 ,  490  may be located radially inward from the push pads  430 ,  440 . When the push pad  430 ,  440  is pressed radially inward, the locking tabs  480 ,  490  may flex radially inward. The locking tabs  480 ,  490  may extend axially downwardly, away from the top wall  410 . The locking tabs  480 ,  490  may be molded integrally with the push pads  430 ,  440  and/or panels  432 ,  442 , and/or may be joined to the pad or panel by a web of material  481 . The locking tab  480 ,  490  may be substantially parallel to the push pad  430 ,  440  or panel  432 ,  442 . The locking tab  480 ,  490  may be approximately equal in width to the entire width of the panel  432 ,  442 , for example as measured between the slots  434 ,  435 ,  444 ,  445 . The width of the locking tab  480 ,  490  may be less than the width of the panel  432 ,  442 , for example approximately three-quarters or less, or approximately half or less, or approximately half. 
     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  480 ,  490  may have an outer surface  485 ,  495  that faces radially outward. The inner and/or outer surfaces  484 ,  494 ,  485 ,  495  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  FIGS. 8 , the closure  400  may have an outer gap  464 ,  465  between the outer surface  485 ,  495  of the locking tab  480 ,  490  and the outer skirt  420 . The closure  400  may have an inner gap  466 ,  467  between the inner surface  484 ,  494  of the locking tab  480 ,  490  and the inner skirt  470 . One or more gaps  464 ,  465 ,  466 ,  467  may be sized to allow passage of the locking lugs  350 ,  360  when the closure  400  is rotated in an opening and/or closing direction. The closure  400  may be configured so that the locking lugs  350 ,  360  pass through one of the gaps (e.g., the inner gap  466 ,  467 ) when the closure  400  is rotated in the closing direction, and through the other gap (e.g., the outer gap  464 ,  465 ) when the closure  400  is rotated in the opening direction. This configuration can provide the advantage of balancing outward deflection of the panels  432 ,  442  upon closing with inward deflection of the panels  432 ,  442  upon opening, thereby reducing deformation or loss of plasticity of the pressing pads  430 ,  440  that may result from a single direction of flexion. 
     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  FIG. 8 , the top wall  410  may have areas of differing thicknesses, including an area of increased thickness  417  and an area of decreased thickness  418 . Relatively thicker portions  417  may provide increased structural support for the closure  400 , particularly in areas of stress, such as along an axis between the push pads. Relatively thinner portions  418  may provide greater flexibility where flexing is desirable or even cost savings, as less material is required. The thicker portions  417  may be located along the major axis  415  of the top wall  410 , substantially parallel to an axis connecting the press pads  430 ,  440 , adjacent a perimeter  475  of the inner skirt  470 , or a combination thereof. 
       FIG. 9  shows a cross-section of the closure  400  of  FIG. 8 , as viewed along line A-A. The closure  400  includes thick portions  417  and thin portions  418 .  FIG. 10  shows a detail of  FIG. 9 . The thickness of the thick portion  417  is represented by M. M may be from about 0.5 mm, or from about 0.75 mm, or from about 1.0 mm, or from about 1.25 mm, or from about 1.45 mm, and to about 5 mm, or to about 4 mm, or to about 3 mm, or to about 2 mm, or to about 1.75 mm, or to about 1.55 mm; M may be about 1.5 mm. The thickness of the thin portion  418  is represented by N. N may be from about 0.5 mm, or from about 0.75 mm, or from about 1.0 mm, or from about 1.1 mm, or from about 1.2 mm, and to about 4 mm, or to about 3 mm, or to about 2 mm, or to about 1.75 mm, or to about 1.5 mm, or to about 1.3 mm. N may be about 1.25 mm. M is typically greater than N. The thickness of the thick portion  417  of the top wall (M) may be at least about 105%, or at least about 110%, or at least about 120%, or at least about 125% greater than the thickness of the thin portion  418  of the top wall (N). The thickness of the top wall  410  at various points can be determined with calipers of suitable precision. 
     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 dessicant. 
     When the closure  400  is in the closed position, the container system  100  may have a MVTR (moisture vapor transmission rate) measurement of less than about 2.0 grams per day per square meter of package surface (g/day/m̂2), or less than about 1.0 g/day/m̂2, or less than about 0.75 g/day/m̂2, or less than about 0.50 g/day/m̂2, or less than about 0.25 g/day/m̂2, 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 . 
     Container Systems 
     The present disclosure relates to container systems  100 . As shown in  FIG. 11 , the container systems  100  may be a two-piece container system  100  that comprises a closure  400 , as described above, and a container  200 . The container system  100  may be adapted for containing any suitable contents, described in more detail below. As used herein, the terms “container” and “container body” are substantially interchangeable when the container system  100  does not include a shroud  300 . 
     The container system  100  or any part thereof, may be formed utilizing any suitable materials. The container  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 shroud  300  may comprise polypropylene. 
     The container  200  may be formed of a clear, transparent, or semi-transparent material, while the closure  400  is 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  250 ) may be formed of substantially opaque materials. The closure  400  and/or shroud  300 , when formed of a substantially opaque material, can mask some of the empty volume at the top of the container body  250  when the container body  250  is formed of a clear material. 
     The materials used to form the container system  100  may have one or more colors. The container body  250 , 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  250  may be a different color than the closure  400  and/or the shroud  300  (if present) (e.g., white container body 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). 
     As shown in  FIGS. 11 and 12 , the container  200  may comprise walls that define an interior volume  202 . The container  200  may include a bottom wall  210 , a front wall  211 , a rear wall  212 , and two side walls  213 ,  214 . The front wall  211  and rear wall  212  may be relative flat, and the two side walls  213 ,  214  may be relatively curved, providing a relatively rounded appearance when viewed from the front. The curved side walls  213 ,  214  may include a flat portion  215 , which can be useful to minimize wear-and-tear when two container bodies are touching during transport, storage, and/or display. The container  200  may also include an upper wall  216 . 
     As shown in  FIG. 12 , 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  200  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  200  shown in  FIG. 12 , the major horizontal dimension  204  is from one side wall  213  to the other side wall  214 , specifically as measured at the flat portions  215 . In the same container  200 , the minor horizontal dimension  206  is from the front wall  211  to the rear wall  212 . Typically, when a container  200  is displayed in a retail environment, it is desirable to present the container  200  in such a way so that the consumer is most likely to view a wall that is parallel with the major dimension (here, the front wall  211 , or less preferably the rear wall  212 ), as it tends to provide the most space for communication and/or artwork. 
     The internal volume  202  may have a volume of at least about 0.5 L, or at least about 1 L, or at least about 2 L, or at least about 3 L, or at least about 4 L, or at least about 5 L, or at least about 6 L. The internal volume 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 interior volume  202  may comprise a composition  500 . The composition  500  may be in the form of articles  510 . The articles  510  may be sized to fit in an adult human hand. The articles  510  may comprise a water-soluble film  520  that encapsulates the composition in at least one compartment  530 , preferably wherein said composition is a household care composition. Compositions  500  are described in more detail below. 
     The container  200  may include a rim  220  at an upper portion of the container  200 . The rim  220  may define a container opening  222 . The container opening  222  allows access the interior volume  202 . 
     The container  200  may include a container neck  230  that projects axially upwardly and away from the interior volume  202 . The container neck  230  may project upwardly from an upper wall  216  of the container  200 . The container neck  230  may terminate with the rim  220 . 
     The container neck  230  may include a complimentary connecting feature  330 , such as threads  332  or thread grooves, that can mate with a connecting feature of the closure  400 . The inner skirt  470  of the closure  400  may comprise at least one thread  462  that connectably engages with a neck  230  of the container  200 . 
     The container  200  may include handle portions  217 ,  218 . The handle portions  217 ,  218  may be molded as part of the walls. 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  200  may include two handle portions  217 ,  218 . 
     The container  200  may comprise at least a first locking lug  350  configured to engage the first locking tab  480  of the closure  400  when the closure  400  is engaged with the container  200  in a closed position. Typically, the engagement of the first locking lug  350  and the first locking tab  480  prevents the closure  400  from being rotated in an opening direction until the first push pad  430  is pressed radially inward. 
     The container  200  may comprise a second locking lug  360  configured to engage a second locking tab  490  of the closure  400  when the closure  400  is in the closed position. Typically, the engagement of the second locking lug  360  and the second locking tab  490  prevents the closure  400  from being rotated in an opening direction until the second push pad  440  is pressed radially inward, preferably at the same time as when the first push pad  430  is pressed. 
     The locking lugs  350 ,  360  may be located on or adjacent a radius that is substantially parallel to the major dimension of the container  200 . 
     As shown in  FIG. 13 , the container system  100  may be a three-piece container system  100  that comprises a closure  400  and a container  200 , where the container  200  comprises a shroud  300  and a container body  250 . The shroud  300  may be connectably engageable with the container body  250 . The closure  400  may be connectably engageable with the shroud  300 . 
     The shroud  300  may have a neck  310  extending axially from a shoulder  320  of the shroud  300 . The neck  310  may terminate in a rim  314 . The rim may define a shroud opening  340 . The shroud opening  340  may be larger than an opening  256  on the container body  250 . 
     The shroud  300  may comprise at least the first locking lug  350  configured to engage the first locking tab  480  of the closure  400  when said closure  400  is engaged with the shroud  300  in a closed position, where the engagement of said first locking lug and said first locking tab  480  prevents said closure  400  from being rotated in an opening direction until said first push pad  430  is pressed radially inward. The shroud  300  may comprise the second locking lug  360 . The locking lugs  350 ,  360  may be on a shoulder  320  of the shroud  300 , which may be adjacent the opening  340 . 
     The container body  250  may have a rim  254  that defines an opening  256  that provides access to the interior volume  202 . The container body  250  may include a neck  252 . The neck  252  may include a shroud-connecting feature  232 , such as threads, thread grooves, or a rib  233 , that can mate with the shroud  300  to attach the shroud  300  to the container body  250 . 
     Compositions 
     The container systems  100  of the present disclosure may contain any suitable material or composition  500 . Typical materials and compositions include, but are not limited to, fabric care treatments, hard surface cleaners, soaps, shampoos, conditioning agents, pesticides, paint, solvents, industrial chemicals, industrial hardware (e.g., nails, screws, etc.), medicines, pills, food, and the like. The material may be water-sensitive material, meaning that the material has a tendency to dissolve or degrade when exposed to liquid water or water vapor. 
     Non-limiting examples of useful compositions include light duty and heavy duty liquid detergent compositions, hard surface cleaning compositions, detergent gels commonly used for laundry, bleach and laundry additives, shampoos, body washes, and other personal care compositions. Compositions may take the form of a liquid, gel, solid, or mixtures thereof. Liquid compositions may comprise a solid. Solids may include powder or agglomerates, such as micro-capsules, beads, noodles or one or more pearlized balls or mixtures thereof. Such a solid element may provide a technical benefit, through the wash or as a pre-treat, delayed or sequential release component; additionally or alternatively, it may provide an aesthetic effect. 
     In some aspects, the compositions may comprise one or more of the following non-limiting list of ingredients: opacifier; antioxidant; fabric care benefit agent; detersive enzyme; deposition aid; rheology modifier; builder; bleaching agent; bleach precursor; bleach catalyst; chelant; perfume; whitening agent; pearlescent agent; enzyme stabilizing systems; scavenging agents including fixing agents for anionic dyes, complexing agents for anionic surfactants, and mixtures thereof; optical brighteners or fluorescers; soil release polymers; dispersants; suds suppressors; dyes; colorants; hydrotropes such as toluenesulfonates, cumenesulfonates and naphthalenesulfonates; color speckles; colored beads, spheres or extrudates; clay softening agents. Additionally or alternatively, the compositions may comprise surfactants and/or solvent systems. 
     The composition may be a flowable composition, such as a free-flowing granular or powder composition. In such cases, the container system  100  may further comprise a scoop adapted to fit into the container system  100  and to scoop the flowable composition. 
     The container systems  100  described herein are particularly useful for containing compositions in the form of an article  510 . The article  510  may be suitable to be grasped by an adult human hand. Such articles  510  may have an article width  512  of from about 10 mm to about 100 mm, or from about 20 mm to about 70 mm, or from about 35 mm to about 55 mm, or from about 40 mm to about 50 mm. If the article  510  is rectangular in shape, the article width  512  is measured as the greatest distance between two parallel sides. When an article has a variable width, the article width is the average of such widths. The article width  512  may be from about 5% to about 90% of the length of the major axis of the container opening  222 . Such articles may have a height, of from about 10 mm to about 100 mm, or from about 15 mm to about 70 mm, or from about 20 mm to about 50 mm, or from about 25 mm to about 35 mm. When an article  510  has a variable height, the article height is measured at the maximum height of the article. 
     Typically, the container systems  100  described herein are useful for containing articles  510  of unitized doses of a composition (e.g., in counts of 50, 66, 77, etc.), typically of a cleaning composition, more typically of a laundry detergent or hard surface treatment composition.  FIG. 14  shows an example of a unitized dose article  510 . The unitized dose article may be a pouch. The pouch may be formed from a water-soluble film  520 , such as a polyvinyl alcohol film, including those available from MonoSol, LLC. The film  520  may encapsulate the composition  500  in a compartment  530 . The pouch may comprise a single compartment, or it or may comprise multiple compartments  530 ,  532 ,  534 . The pouch may contain various compositions, which may be of varying colors that may be seen from outside of the pouch. A multi-compartment pouch may contain the same or different compositions in each separate compartment. The compartments may be side-by-side or superposed, for example one or two smaller compartments  532 ,  534  superposed on one larger compartment  530 . This multi-compartment feature may be utilized to keep compositions containing incompatible ingredients (e.g., bleach and enzymes) physically separated or partitioned from each other. It is believed that such partitioning may expand the useful life and/or decrease physical instability of such ingredients. 
     The compositions  500  of the unitized dose articles  510  typically have low levels of water. In some aspects, the compositions comprise less than about 50%, or less than about 30%, or less than about 20%, or less than about 15%, or less than about 12%, or less than about 10%, or less than about 8%, or less than 5%, or less than 2% water by weight of the composition. In some aspects, the composition comprises from about 0.1% to about 20%, or from about 1% to about 12%, or from about 5% to about 10% water by weight of the composition.
