Discharge parts of the present invention owing to do not produce from the backflow of discharge orifice side direction upstream side, so the residual liquid after discharging operation finishes does not flow in the discharge portion, and remain in discharge orifice around.For this reason, use inside to have the lid that absorbs material, remain near the liquid (residual liquid) of discharge orifice with absorbing after material absorption discharging operation finishes, like this, when dripping operation once more, this residual liquid can not discharged (seeing Figure 17 and Figure 27).
Cavernous body is implemented antibacterial treatment, and when making it with the discharge orifice direct contact, the time one is grown, and antiseptic can ooze out from cavernous body, on discharge orifice.For this reason, also can make not direct contact of cavernous body and discharge orifice,, absorb the residual liquid (seeing Figure 35) of the discharge orifice of being extruded by interior surface with being located at interior surface absorption material on every side.
Concrete example as absorbing material for example has: by the cavernous body that urethane or polyethylene foamed etc. constitutes, and the cloth that nonwoven fabrics, absorbent cotton, gauze etc. constitute, paper, Aquagel etc.During the formation of cavernous body, for example can adopt the existing known various materials of urethane or polyethylene foamed etc.When cavernous body is implemented antibacterial treatment, preferably for example can after cavernous body is made,, make the surface of medicament, perhaps the medicament of antiseptic etc. be refined in urethane or the polyethylene in advance attached to cavernous body by modes such as coatings.In addition, the material that also can adopt absorption material itself to have antibiotic property.
When above-mentioned cloth, paper, Aquagel etc. are implemented antibacterial treatment, for example can implement silane coupled or be coated with the processing method of selenium etc. them.As the concrete example of Aquagel, for example, the material (TOHKEMY 2002-53629 communique, TOHKEMY 2002-53762 communique) that can adopt Polymer and water-swellable clay mineral assemblage by (partially) isoallyl acid amides system etc. to form.
(discharging the formation material of parts, lid and vessel)
Form the resin of discharging parts, lid and vessel, polyethylene (PE), polypropylene (PP) etc. are for example arranged.PE or PP are safe material aspect medical, so when container of the present invention is an eye drop container when accommodating the container of soup like that, PE or PP are the most suitable.
In order to prevent to remain near the remaining liquid that waits the discharge orifice behind the discharging operation more or to be housed in liquid corruption in the vessel etc., also can in forming the resin of discharging parts, lid and vessel, practice to go into anti fouling composition etc. in advance.As the concrete example of anti fouling composition, the 4th grade of ammonium salt (for example the commodity of イ ヌ イ (strain) system are called " dimer 38 (R) ", " dimer 136 (R) " of this Co., Ltd.'s system) etc. for example arranged.
In addition, also can be after the formation of discharging parts, lid and vessel, make anti fouling composition attached to its inside face etc. with modes such as coatings, perhaps, when the formation of discharge parts, lid and vessel, implement the surface treatment of silane coupled grade.To forming the resin of discharge portion etc., also can employing itself has the resin of antibacterial activity.
Industrial applicibility
Discharge parts of the present invention can highly prevent from the liquid return of discharge orifice discharge, and prevent the backflow intrusion of side upstream along with liquid such as germ and dust, after discharging processing and discharging operation, container are successfully restored.
In the discharge parts of the present invention, the distortion of valve body is to be caused by the low hydraulic pressure of logical hydraulic pressure than the ventilation filtering bodies, so, during discharging operation, do not produce liquid at the air extractor vent place and leak, can realize discharge effectively from discharge orifice.And, because the opening of discharge orifice and/or the stream that links to each other with discharge orifice, can not be by existing to the ventilation compacting of ventilation filtering bodies from the outside, so, when vessel restores, do not produce: outer gas be can't help air extractor vent and the problem that flows into from discharge orifice, or the problem that spills from discharge orifice of liquid in container thereupon.Therefore, discharge parts of the present invention can prevent to heavens from the backflow of the liquid of discharge orifice discharge, and prevent germ and dust along with the above-mentioned backflow intrusion of side upstream, after discharging processing and discharging operation, container are successfully restored.
In addition, discharge parts of the present invention, not as the antibiotic property container of aforementioned TOHKEMY 2001-179017 communique and TOHKEMY 2001-206454 communique record, to dispose porous filtering bodies in discharge portion, so, when even liquid in container is suspension, the discharge orifice possibility of jamming is also extremely low.Though should stop up because of valve body or to discharge hole size, material etc. different,, usually when the particle diameter of suspension particle is 50 μ m, with regard to the obstruction that can not produce discharge orifice.
Container of the present invention has discharge parts of the present invention at its oral area, so can prevent to heavens: the liquid return of discharge is in vessel, or germ, dust such as bacterium etc. is invaded in the vessel thereupon.Therefore, needn't add the medicament (for example anti fouling composition) that is used to prevent liquid in container corruption or deterioration, perhaps can reduce the adding of medicament as best one can.In addition, container of the present invention does not adopt porous filtering bodies in discharge portion, therefore, can prevent the obstruction of discharge orifice, except the upstream side at discharge orifice has logical liquid filtering bodies, even liquid in container is a suspension, can successfully discharge yet.
Container of the present invention in discharging the stream of parts or in the vessel, also has the interior plug that is keeping sliding freely, in this plug when container does not use preferably with the stream inwall butt of discharging parts, with the stream locking.At this moment, before container is brought into use, can airtightly liquid in container be remained germ-free condition, and, at unused state, can prevent that liquid in container and valve body or ventilation filtering bodies from contact, so, can keep steady quality between for a long time.Container of the present invention for example is suitable for as the eye drop container of accommodating eyedrop.
