    • The invention relates to a pump that can be operated manually or by a utensil held in one hand by a user, characterised in that it comprises an elastically deformable chamber (10), the inside of which can contain a liquid or viscous product (8) and the outside of which can be brought into contact with the air, in a gap (7) in said chamber (10), and with a replacement fluid, in an opening (6) in said chamber. The invention is also characterised in that the chamber can be elastically deformed by pressure exerted by a user, in order to create an overpressure in the product (8) in relation to the outside, and to open the gap (7), letting a useful amount of the product (8) escape; in that the chamber (10) can elastically regain its original form when the user releases the pressure, in order to create a depression in the product (8), in the presence of a flow of replacement fluid via the opening (6) towards the inside, and to close the gap (7); and in that the wall of the chamber (10) is essentially plane to the vicinity of said gap (7).
    • 本发明涉及一种能够由用户手动操作或由一只手保持的器具操作的泵,其特征在于,其包括可弹性变形的室(10),其内部可容纳液体或粘性产品(8) 并且其外部可以与空气接触,在所述室(10)中的间隙(7)中,并且在所述室中的开口(6)中与替换流体接触。 本发明的特征还在于,通过使用者施加的压力,腔室可以弹性变形,以便在产品(8)中相对于外部产生超压,并且打开间隙(7),使得有用的 产品量(8)逃逸; 因为当用户释放压力时,室(10)可以弹性地恢复其原始形式,以便在存在经由开口(6)的替换流体流向产品(8)的情况下在产品(8)中产生凹陷 内部,并缩小差距(7); 并且室(10)的壁基本上平行于所述间隙(7)的附近。
