Definitions
- the present invention relates to a container with a filter that can be suitably used as a sterile eye drop container.
- Patent Document 1 JP 2001-114328 A
- This conventional sterile eyedropper container has a bottle formed by laminating an inner layer releasable from the outer layer on the inner surface of an outer layer that can be squeezed, and a bottle provided at the mouth of the bottle and housed in the body of the inner layer. And a stopper having a discharge path for discharging the discharged content liquid.
- a dispensing valve and a filter are provided in the discharge path of the bottle.
- the valve flange, the valve head, and the connector sleeve are integrally formed of an elastic material such as silicone rubber. It is a thing.
- This valve head is provided with a cross-shaped orifice having a cutting force at the center thereof, and the connector sleeve has a relatively thin and flexible structure so that it can be easily deformed. Therefore, when the outer layer is squeezed and the pressure of the inner layer body increases, the dispensing valve elastically deforms so as to displace the valve head to the downstream side and opens the orifice. The contents will flow down from the filter to the downstream side, and the contents will be dripped. When the pressure in the body of the inner layer is removed, the dispensing valve displaces the content liquid remaining in the discharge path to the upstream of the filter by displacing the valve head upstream with the orifice closed. It was deformed so as to absorb and return, thereby preventing external contamination of the content liquid.
- the present invention particularly in an eye dropping container or the like, sucks the liquid remaining on the downstream side of the filter back to the upstream side of the filter, and avoids the so-called air-lock state so that the dripping of the content can be accurately performed. It is an object of the present invention to provide a filter-equipped discharge container which can be performed and can reduce cost.
- the present invention takes the following technical measures.
- the present invention includes a bottle in which an inner layer releasable from the outer layer is formed on the inner surface of the outer layer, and a plug provided at the mouth of the bottle.
- a discharge path for discharging the content liquid contained in the body of the inner layer is provided, and a filter is provided in the discharge path.
- the pressure difference between the internal negative pressure and the atmospheric pressure of the inner layer is controlled by the filter. It has a restoring property that expands to be larger than the filtration resistance, and creates a negative pressure inside the inner layer due to the restoring property of the inner layer, thereby sucking residual liquid remaining on the secondary side of the filter to the primary side of the filter.
- a discharge container with a filter is controlled by the filter.
- the inner layer when the bottle body is pressed, the inner layer is deformed and the inner solution can be dripped from the inside of the body via the discharge path.
- the inside becomes negative pressure, and the solution inside the filter on the secondary side (discharge downstream side) is sucked back to the primary side (discharge upstream side).
- the above-mentioned function can be achieved without providing a specially-shaped dispensing valve as compared with the conventional one, so that the cost can be reduced.
- the filter has hydrophilicity, whereby the inside solution is filled in the filter, so that the outside air is more likely than the filter. It is possible to accurately prevent entry into the upstream side.
- the elastic restoring force of the inner layer is preferably provided such that the pressure difference between the internal pressure of the inner layer and the atmospheric pressure is smaller than the resistance that allows air to pass through the filter impregnated with the internal solution. . This can more reliably prevent air from entering the upstream side of the filter.
- the body of the inner layer is made of synthetic resin, and the average thickness of the body is
- It is more preferably 0.1 mm or more, preferably 0.35 mm or more, and more preferably 0.5 mm or less, more preferably 0.4 mm or less. It can be constituted by elastic restoring force.
- the outer layer has an inlet for introducing outside air between the outer layer and the inner layer.
- the outside air flows in through the inlet, and the pressure between the outer layer and the inner layer becomes atmospheric pressure.
- the pressure difference can be reliably provided in a desired range. It is possible to provide a check valve at the inlet, but it is also possible to use an opening force that is closed when the bottle body is pressed.
- the present invention particularly in an ophthalmic container or the like, the content liquid remaining on the downstream side of the filter is sucked back to the upstream side of the filter, and the so-called air-lock state is avoided so that the dripping of the content accurately. Can be performed, and the cost can be reduced. Furthermore, in the conventional eye dropper, when the refrigerated container is taken out of the refrigerator compartment, the temperature inside the container rises due to room temperature, and the liquid inside the container expands, causing the liquid to leak out. Possible Forces According to the present invention, there is no liquid pool under the filter, so there is no such leakage.
