    • Pump operable 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 is suited to containing a liquid or viscous product (8) and the outside of which is intended to be brought into contact with air at a slit (7) made in this chamber (10) and brought into contact with a replacement fluid at an opening (6) made on said chamber, in that the chamber is suited to deforming elastically, by a pressing of a user, to create a higher pressure in the product (8) compared to the outside, and to open the slit (7), allowing a useful volume of product (8) to escape from it, in that the chamber (10) is suited to making its deformation elastically disappear, following the cessation of the pressing of the user, to create a lower pressure in the product (8), in the presence of a flow of replacement fluid through the opening (6) towards the inside, and to close the slit (7), and in that the wall of the chamber (10) is essentially planar in the vicinity of said slit (7).
    • 泵可手动操作或由使用者一只握住的器具操作,其特征在于,其包括可弹性变形的室(10),其内部适于容纳液体或粘性产品(8),并且其外侧是 旨在与在该室(10)中制成的狭缝(7)上的空气接触并且与在所述室上形成的开口(6)处的替换流体接触,因为所述室适于弹性变形, 通过使用者的按压,与外部相比在产品(8)中产生更高的压力,并且打开狭缝(7),允许有用体积的产品(8)从其中逸出,因为室 (10)适于使其变形弹性消失,随着使用者的按压停止,在产品(8)中产生较低的压力时,在通过开口(6)的替换流体流的存在下向着 内部并且关闭狭缝(7),并且室(10)的壁 )在所述狭缝(7)附近基本上是平面的。
