When a tip of a single finger is inserted into receptacle 1 to bring the artificial fingernail 7 attached to a natural nail into contact with absorbent 2, resin of the artificial nail 7 is dissolved or softened by the solvent, and the artificial nail 7 can be easily scrapped off the natural nail in a relatively short period of time.

Abstract: An electric current detector is provided wherein loose arrangement of conductor 6 in opening 5 provides an air gap between the conductor 6 and plastic package 4 in opening 5 to prevent close contact of conductor 6 to plastic package 4. When heat and heat stress are produced in conductor 6 by a large electric current flowing through conductor 6 during measurement, air gap surely prevents heat and heat stress from traveling to Hall effect sensor 2 and plastic package 4 while a part of heat in conductor 6 is radiated into air in opening 5. Thus, the loose arrangement of conductor 6 can restrict or reduce deterioration of electric property in Hall sensor 2 and degradation of mechanical property in plastic package 4 by heat and heat stress in conductor 6. Also, the loose arrangement ensures and facilitates attachment of the detector 1 in position on a surface of a substrate, and enables to maintain conductor 6 at the same level as lead terminals 3 of the detector.

Abstract: The invention concerns a dispensing and closure system arranged at the top of a container, in particular a soft tube comprising a liquid or pasty product, which is delivered by pressing on the tube. The invention is characterized in that it consists of a valve comprising two concentric elements, one of which forms a mobile cylindrical delivery valve and the other forms a cylindrical body exiting from a plate linked to the tube. The two elements defined between them an annular gap through which the product passes. When a manual pressure is exerted on the tube, it causes the product to act directly on the delivery valve causing the latter to open, countering an elastic return member, so as to allow the product to escape from the tube, when the pressure is exerted thereon and to automatically close the delivery valve when the pressure is released, preventing the possible return of the product already dispensed from returning inside the tube.
