Description
Technical field
The present invention relates to a kind of metering pump device, it have that a container that is used to admit a kind of fluid that has a variable volume can link to each other with described seal of vessel ground with one, can manually operated pump, described pump has an exit orifice that is communicated with surrounding environment.The invention still further relates to application and a kind of method that is used to make described metering pump device of this metering pump device in addition.
Background technique
By the output unit of the known a kind of fluid of DE10049898 C2, utilize described device for example can from a container, the medicine or the cosmetics of liquid state be exported quantitatively.Employed for this reason metering pump does not have air balance works (Luftausgleich), and wherein said liquid is received in container in the inner pouch with respect to the surrounding environment sealing, and described inner pouch withers when emptying.
Usually like this come this inner pouch is filled with liquid such as medicine or cosmetics, consequently in inner pouch, retained residual air.This is undesirable owing to various reason.Airborne oxygen contacts with described liquid all the time when depositing like this, and this can cause the shortening of resting period or the sterility of liquid to reduce.But to fill be very complicated and expensive to fluid container in gnotobasis or under shielding gas.
Have only in addition when not retaining residual air in the inner pouch after filling, just may empty described bag fully.When not keeping transmitter installation upright when in operation, the residual air in the inner pouch also can play interference effect.Not fully can aspirate residual air by pump during vertical orientation at described metering pump device like this, with the output in the bag internally of described residual air rather than described liquid.This is undesirable when administration particularly, and for example nose spray, eye spray or ear's spray accurately keep described transmitter installation vertically to use and can only carry out very difficultly for the administration of described medicine.
Therefore in DE10049898 C2, advise, between the inwall of the outer wall of the piston of metering pump and pressure rigid body, form a passage that is used to aspirate residual air, described passage is communicated with described inner pouch by an opening that is arranged on the pump case on the one hand, and the cover plate of a valve formula by pump inside is connected with surrounding environment on the other hand.Can may there be residual air by the suction after filling described inner pouch of described passage, to avoid above-mentioned shortcoming.But the described passage that is formed for the residual air in the inner pouch requires that high precision is arranged when making described pump.In addition because the labyrinth of pump uprises the manufacture cost of this transmitter installation.
Summary of the invention
Therefore the objective of the invention is, a kind of metering pump device that starts described type is provided, in described metering pump device, can utilize simple structure to be pumped in the residual air that remains in when filling described container in the described container.Should also provide a kind of simple method that is used to make this metering pump device in addition.
Basically realize like this according to purpose of the present invention, a bypass passageways that is distributed in the outside of described pump promptly is set, described bypass passageways makes described container be connected with surrounding environment and can be by a closure member sealing.Because described bypass passageways is not to be integrated in the described pump itself, can keep described pump structure simple especially.Can use cheap and simple pump thus.By pumping function is separated with the pumping function that is used for residual air, can use a large amount of various pumps in addition, thereby can be complementary with application purpose respectively the selection of pump.Described bypass passageways also makes and can aspirate residual air efficiently from described container simultaneously, wherein after suction, can seal described bypass passageways in this wise, thereby not have undesirable medium-as uncleanly ambient air-container as described in can entering in some cases by described closure member.
