Abstract: A handle for an oral-care implement for safe and hygienic use by multiple users includes an electrical motor and a detachable head. The handle has a display for displaying instructions to control functional operation of the handle, a microcontroller for controlling the motor and the display, and at least one switch to allow a user to control the functional operation of the handle, including causing the output element to vibrate in at least one oral-hygiene mode having an oral-hygiene frequency and causing the output element to vibrate in a disinfection mode when the handle is being disinfected before or after being used for the oral-hygiene routine. The disinfection mode has a modulated frequency, different from the oral-hygiene frequency, and alternating up and down between a low modulated frequency and a high modulated frequency, wherein the high modulated frequency is at least 50 percent greater than the low modulated frequency.

Abstract: A handle for an oral-care implement, the handle comprises an electrical motor arranged to drive an output element structured and configured to couple the handle and a head attachable to and detachable from the handle; and a microcontroller for controlling the motor and to cause the output element to vibrate in (a) at least one oral-hygiene mode during which the oral-care implement is being used for an oral-hygiene routine, wherein the output element is vibrating at a substantially constant frequency, and (b) a disinfection mode during which the handle is being disinfected, before or after being used for the oral-hygiene routine, wherein the output element is continuously vibrating at a modulated frequency alternating within a frequency range of between about 140 Hz and about 250 Hz, for a duration of the disinfection mode.

Abstract: A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels. The projections and channels are arranged in an alternating manner. Each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius, and each projection is end-rounded thereby forming a curvature. The curvature has a diameter, and the ratio of the diameter of the curvature of the projection to the radius of the curvature of the channel is from about 0.2 to about 1.5.

Abstract: A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels are arranged in an alternating manner. The cross-sectional area has an outer diameter, and each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius which is within a range from about 0.015 mm to about 0.12 mm, and the ratio of the outer diameter to the radius is within a range from about 2.5 to about 12.

Abstract: A package kit for storing a plurality of products includes a primary package and a secondary package. The primary package has a plurality of individually sealed and separately detachable cavities. The secondary package is sandwiched between a back panel and a front panel of the secondary package. The front panel includes a first aperture and a second aperture for displaying at least a portion of the primary package. A first outer circumferential portion at least partially surrounds the first aperture, and a second outer circumferential portion at least partially surrounds the second aperture. The front panel includes an elevated portion disposed between the apertures and extending from the first and second outer circumferential portions.

Abstract: A package kit includes a plurality of primary packages, each having a cavity for storing one of a plurality of products, and a secondary package that stores the plurality of primary packages and includes a back and front panels between which the primary packages are sandwiched. The front panel has a first row of apertures, each displaying at least a portion of a primary package. A first outer circumferential portion of the front panel partially surrounds the apertures and is attached to the back panel, and a second outer circumferential portion of the front panel is attached to the back panel. The front panel includes an elevated portion between the first and second outer circumferential portions. The first outer circumferential portion has a first and second limbs, and the second outer circumferential portion has a third and fourth limbs. The elevated portion extends from, and is hingeably connected to, the first, second, third, and fourth limbs.

Abstract: A pack of tissues includes multiple interfolded tissues arranged in a stack and an external envelope enclosing the stack. The external envelope includes a dispensing orifice and the tissues are folded so as to include a leading panel, an optional central panel, a trailing panel, a leading fold and an optional trailing fold, wherein the leading fold separates the leading panel from the central panel and the optional trailing fold separates the optional central panel from the trailing panel. The stack has a first tissue and an second tissue, the second tissue being positioned next to the first tissue in the stack and further away in the stack from said dispensing orifice. The tissues are interfolded so as to have an overlapping portion of the first tissue under a portion of the second tissue. The surface area of the overlapping portions is not constant throughout the stack; preferably it increases with the distance to the dispensing orifice.
