A pen includes: an ink reservoir configured to store an ink; and a pen tip section including an ink application part configured to apply the ink to an ink application object. The ink application part of the pen tip section includes: a rigid tip made of a rigid material and having a hemispherical outer surface, an inner surface facing toward the ink reservoir, and a penetration part penetrating from the inner surface side to the outer surface side of the rigid tip; and at least one foam body filled in the penetration part at least on the side of the penetration part close to the outer surface side of the rigid tip, and provided with at least one air bubble formed to communicate from the outer surface side of the foam body to the inner surface side of the foam body.

A dropping pipette-type cosmetic container includes a container body having a discharge port formed on one side thereof, a downward movement limiting member coupled to the other side of the container body, a pressing button rotatably coupled to the downward movement limiting member and configured to move downward by pressurization, and an elastic member for elastically supporting the pressing button; the downward movement limiting member has multiple main grooves formed thereon at different depths and has auxiliary grooves formed thereon so as to have the same depths as those of respective main grooves, which have different depths, and to constitute pairs therewith; main protrusions to be inserted into the main grooves and auxiliary protrusions to be inserted into the auxiliary grooves are formed on the pressing button so as to correspond to each other.

An electronic device, including a housing that is metal or lined with an electrically conductive material, at least one electrical component, and a battery cell positioned in a cavity in the outer housing, the battery cell integrated into the electronic device. The battery cell includes a first current collector and an active cell core. The first current collector is the electrically conductive material of the outer housing of the electronic device and connects to the at least one electrical component. The active cell core includes a first active material in adjacent facing relation to and electrically coupled to the first current collector, a second active material; a separator positioned between the first active material and the second active material; and a second current collector electrically coupled with the second active material, wherein the second current collector connects to the at least one electrical component.

A writing instrument comprising a housing extending in a longitudinal direction and having a radial direction, and first and second concentric writing tips, the second writing tip arranged around the first writing tip, each writing tip received in the housing and able to assume an operating configuration, the housing comprising, at a longitudinal end, a deformable nose at least in the radial direction, the deformable nose comprising at least one slit extending in the longitudinal direction, the deformable nose not being deformed when only the first writing tip is in an operating configuration and the deformable nose being deformed when the second writing tip is in an operating configuration, the deformable nose comprising an exit opening of the first and second writing tips, the diameter of the exit opening being greater than the diameter of the first writing tip and less than that of the second writing tip.

A pen dispenser is provided with a tube having an open top for holding a fluid to be dispensed. A valve housing made of plastic and having channels on an inner wall is also provided. There is also an applicator nib made of plastic, along with a plastic spring actuator having a plastic button, and a button retainer. In a closed position the plastic spring actuator is sealingly engaged to the valve housing blocking the flow of fluid out around the applicator nib, and in the open position, the plastic spring actuator is depressed so it is no longer sealingly engaged to the valve housing, allowing the fluid to flow through the channels on the inner wall and exit the dispenser around the applicator nib.
