Abstract
System for recharging with viscous liquid a bottle to be recharged from a source bottle inverted above the aperture of the bottle, comprising: a liquid passage opening out through one end inside the bottle, a distinct air passage, which extends from the bottle to the bottle and putting into communication the interior of the bottle and the bottom of the bottle for the rise of air towards the latter, while liquid is transferred from the bottle to the bottle via the liquid passage, a device for restricting the air passage disposed inside the bottle above the end so as to stop, or at least slow down, the rise of liquid in the bottle, and therefore the flow of liquid, when the liquid level in the bottle reaches the restriction device.
Claims19
A system for recharging with liquid a bottle to be recharged from a source bottle containing a viscous liquid, the bottle to be recharged having an aperture disposed above the bottom and the source bottle having an aperture and a bottom opposite to the aperture, the source bottle containing viscous liquid being inverted such that its aperture is disposed above the aperture of the bottle to be recharged, the system comprising:
- a liquid passage which extends between the source bottle and the bottle to be recharged by opening out through an opening end inside the bottle to be recharged and which is able to put into communication the source bottle and the interior of the bottle to be recharged so as to allow the transfer of liquid from the source bottle to the bottle to be recharged through the liquid passage, the liquid passage comprising a liquid conduit provided with the opening end of the liquid passage and which extends axially at least partly inside the bottle to be recharged,
- an air passage distinct from the liquid passage and which extends from the interior to the exterior of the bottle to be recharged through the aperture of the bottle to be recharged so as to allow the discharge of air from the bottle to be recharged while liquid is transferred from the source bottle to the bottle to be recharged,
- a part surrounding the liquid conduit coaxially and providing with the liquid conduit one or several radial spaces defining a reduced passage section of the air passage which is adapted to the viscosity of the liquid, the reduced passage section of the air passage being disposed inside the bottle to be recharged above the opening end of the liquid conduit so as to stop, or at least slow down, the rise of liquid in the bottle to be recharged, and therefore the flow of liquid in said bottle to be recharged, when the liquid level in the bottle to be recharged reaches the reduced passage section of the air passage.
A method for recharging with liquid a bottle to be recharged from a source bottle containing a viscous liquid in a system comprising, on the one hand, a bottle to be recharged having an aperture disposed above the bottom and, on the other hand, a source bottle containing viscous liquid and having an aperture and a bottom opposite to the aperture, the source bottle being inverted such that its aperture is disposed above the aperture of the bottle to be recharged, the method comprising the following steps:
- flowing of liquid from the source bottle to the bottle to be recharged via a liquid passage which opens out through an opening end inside the bottle to be recharged in which the liquid rises,
- discharge of the air contained in the bottle to be recharged through an air passage distinct from the liquid passage and which extends from the interior to the exterior of the bottle to be recharged through the aperture of the bottle to be recharged, while the liquid level rises in the bottle to be recharged,
- stopping or slowdown of the rise of liquid in the bottle to be recharged, and therefore of the flowing of liquid in the bottle to be recharged via the liquid passage, when the liquid level in the bottle to be recharged reaches a reduced passage section of the air passage which is disposed inside the bottle to be recharged above the opening end of the liquid passage, the stopping or slowdown of the rise of liquid in the bottle to be recharged being due to the adaptation between the reduced passage section of the air passage and the viscosity of the liquid.
