It is an object to provide a cylindrical molded article that can inhibit the transmission of components having SP values in a relatively wide range. A cylindrical molded article having a cylindrical resin layer I comprising a vinylidene chloride copolymer; and a cylindrical resin layer II disposed inside the resin layer I and comprising a resin having an SP value of 12.0 (cal/cm.sup.3).sup.1/2 or more, and having a total thickness of 100 m or more.

A marker and stamp system embodied in a double-end device is provided. The device includes a marker end and an opposing stamp end. The stamp end enables the creation of clear and concise group presentations/instructions through the uniform application of predetermined symbols via a stamp applicator portion and marking template, while the marker end facilitates the presentation of tailored, free-hand markings via application of a marker nib.

An oral care implement including a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir, in the body, for storing an oral care fluid; and a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first check valve downstream of the reservoir, and a second check valve downstream of the first check valve and upstream of the fluid outlet. One of the first and second check valves comprises a valve seat defining an opening through which the oral care fluid is flowable, a valve member separate from the valve seat and comprising a stopper movable linearly relative to the valve seat, and a resilient element separate from the valve member and biasing the stopper towards the valve seat.

An all-in-one cleaning device, e.g., such as may be used in cleaning the inside of a shower. The device may provide the ability to dispense the composition carried within the device itself, and scrub the composition into or against the surfaces to be cleaned (e.g., shower walls, floors, corners, etc.). Activation of the dispensing mechanism of the cleaning device may dispense a metered dose of composition, in a generally horizontal direction, onto and/or into a nonwoven or other substrate. The dispensing mechanism may not rely on gravity for dispensing, and may be sealed to prevent unwanted backflow of shower water or other material, preventing contamination.

An all-in-one cleaning device, e.g., such as may be used in cleaning the inside of a shower. The device may provide the ability to dispense a cleaning composition carried within the device itself. The device may include a container housing including an internal reservoir for holding a cleaning composition, and a wall defining a scrubbing side of the container housing. The wall may include a dispensing orifice through which the cleaning composition is dispensed. A hook may be provided extending from the container housing, which is engageable with a substrate (e.g., a scrubbing pad) positioned over the wall defining the scrubbing side of the container housing. An end of the substrate may be held in place over the wall by the hook. Another end of the substrate may be held in place by a hook and loop attachment structure.

[Problems] An object of the present invention is to provide: a thermochromic color-memory composition which effectively expresses a property of being able to interchangeably memorize and retain colors and which is thus applicable to various fields;

and a thermochromic color-memory microcapsule pigment encapsulating the same.

[Solution] Provided is a thermochromic color-memory composition including: (a) an electron-donating color-developing organic compound; (b) an electron-accepting compound; and (c) an ester compound represented by the following Formula (1), as a reaction medium which controls color reaction between the component (a) and the component (b):

##STR00001##

(wherein, R represents an alkyl group having 3 to 18 carbon atoms, a cycloalkylalkyl group having 6 to 11 carbon atoms, a cycloalkyl group having 5 to 7 carbon atoms or an alkenyl group having 3 to 18 carbon atoms; each X independently represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 3 carbon atoms or a halogen atom; and each Y independently represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a methoxy group, an ethoxy group or a halogen atom).

An anti-reversal structure of a stationery container and a cover is provided. The cover is screwed to the stationery container to seal the stationery container for containing a functional solution. The anti-reversal structure includes a first ratchet portion disposed at one side of a threaded portion of the cover and a second ratchet portion disposed at one side of a threaded portion of the stationery container.
