Can and an urging member therefor

A can for containing a product comprising at least one solid component and at least one liquid component, the can with the product at least in a ready-for-sale state, the can comprising:

• a lid bermetically sealing the can and at least partially openable to allow at least partial removal of the product from the can;
• a base opposite the lid and a side wall extending therebetween;
• the base being in the form of an urging member, the urging member having a central axis passing through a center of the urging member along a thickness direction thereof, the urging member comprising:
• an inner side configured to face toward an interior of the can and an outer side configured to face toward an exterior of the can, the inner side defining an inward direction of the urging member and the outer side defining an outward direction of the urging member;
• a peripheral edge, at which the urging member is connected to the side wall at one end thereof, the peripheral edge having a surface which is an outermost surface in the outward direction, said outermost surface defining a reference plane of the urging member perpendicular to the central axis thereof;
• an urgeable area surrounding said axis and having a normal state in which at least a part of said area is outwardly convexly curved toward the central axis at the outer side of the urging member;
• a pattern of elements formed in the urging member and located between said peripheral edge and said central axis, the elements comprising at least one strengthening rib having a top at the outer side of the urging member and a bottom at the inner side of the urging member, the strengthening rib extending along the peripheral edge, and the top being spaced from the bottom of the strengthening rib in the outward direction of the urging member to a distance not exceeding that of a distance between the bottom and the reference plane;
• and a number of urgeability-providing elements located between the central axis and the at least one strengthening rib, said urgeability-providing elements being angularly spaced from each other about the central axis, being radially spaced from the strengthening rib and being configured to provide said urgeable area with the ability to be repeatably elastically displaceable, when the peripheral edge of the urging member is fixed in place, in the following directions:
• (a) in the inward direction of the urging member, upon the manual application of an urging force to the urgeable area by at least one finger of a user, thereby changing the state of the urgeable area from a normal state in which the central portion of the area is disposed at a first location with respect to the reference plane, to a deformed state in which said central portion is disposed at a second location spaced from the reference plane to a greater distance than in the normal state;
• and
• (b) in the outward direction upon release of said urging force, thereby changing the state of said urgeable area from the deformed state to said normal state,
• wherein, the urging member is operable, only when the lid is at least partially opened, to be repeatedly urged inwardly by a user applying thereto the urging force, thereby causing the urging member to function as a membrane in a pump directed to pump out the at least one liquid component from the can via the at least partially opened lid.
