Definitions
- the invention relates to a pressure equalization device for a double container, which consists of a rigid outer container and a collapsible inner container.
- the inner container contains a liquid.
- the invention aims to provide a device which is suitable for the pressure equalization between the ambient air and the gas space between the inner container and the outer container, which is economical to produce and which is protected against clogging.
- a container which consists of a rigid outer container and an easily deformable inner bag.
- This container is made by coextrusion blow molding of two thermoplastic materials, which do not connect with each other.
- the outer container has a closed bottom and contains at least one opening for pressure equalization between the environment and the space between outer container and inner bag.
- the outer container has in its shoulder portion at least one unwelded seam between two opposite non-welded together wall sections of the outer container. Preferably, two unwelded seams are provided in the shoulder region of the outer container.
- the inner bag is sealed in this area by welds. Due to the unwelded seam sections in the shoulder region of the outer container, air can enter into the intermediate space between outer container and inner bag.
- the non-welded edge edges at the open seam in the shoulder region of the outer container tend to lie against each other under reduced pressure. Therefore, it is further proposed to preferably provide a plurality of holes in the upper region of the wall of the outer container as ventilation openings, which are produced for example by ultrasound or mechanically by perforating the outer container. All openings in the wall of the outer container in the shoulder area and upper wall area are covered by means of the housing of the patch on the container pump.
- the double containers of the prior art contain open seams or holes in the outer container.
- the outer container is invariably made of a thermoplastic material.
- the object is to provide a device for a double container, which is suitable for the pressure equalization between the ambient air and the gas space between the inner container and the outer container, even if the inner container contains a liquid which is volatile or contains a volatile component, against which the inner container is limited diffusion-tight. Even with years of storage of the filled double container and months of proper service life of the double container, the amount of liquid in the inner container or the concentration of liquid components only in one Change extent that is much smaller than when using one of the known double container.
- the equivalent diameter of the at least one channel is the diameter of a circle whose area is equal to the cross-sectional area of the at least one channel.
- the at least one channel may preferably be one hundred times to one-tenth, more preferably ten to one times as long as the equivalent diameter of the at least one channel.
- the channel preferably has a cross section which is about as wide as it is high, that is to say preferably a round or approximately square cross section or a triangular cross section.
- the channel cross-section can be rectangular, trapezoidal, semicircular, slot-shaped or irregularly shaped.
- the ratio of the side lengths of a slot-shaped channel can be up to 50 to 1.
- Several channels may be arranged regularly, for example at the crossing points of a grid, or irregularly, for example statistically distributed.
- the cross-sectional area of the channel is less than 1 mm 2 and can be up to the range of some a thousand square microns.
- the channel may be straight or curved or shaped as a meander, a spiral or a screw.
- the channel may, preferably as a bore, be mounted in the wall of the outer container. Further, the channel can be mounted in a - preferably made of plastic - insert attached to the wall of the outer container, preferably in an inverted recess in the bottom of the outer container, tightly mounted. In this case, the space facing the end of the channel is in communication with an opening in the wall of the outer container. This opening has a larger cross section than the channel.
- At the one end of the channel preferably at the end facing the environment, may be attached as dust protection, a gas-permeable filter, for. B. a non-woven fabric or a body made of open-pored sintered material.
- the environment facing the end of the channel may be closed during the storage period of the filled with a liquid double container with a sealing foil which is completely or partially demolished or pierced prior to the first removal of liquid from the inner container.
- the wall of the at least one channel may be smooth or rough.
- the at least one channel can be produced as a microbore, for example by means of a laser beam, in a plate.
- a meandering or spiral channel may be generated, for example, by selective etching of a silicon surface;
- Such a channel may have a triangular or trapezoidal cross-section.
- a channel having a triangular cross section and almost any shape can be obtained by embossing a (metal) surface.
- a helical channel may be mounted on the surface of a cylinder inserted in a pipe. Further, such a channel may be mounted on the mantle surface of a hollow cylinder in which a cylindrical body is inserted. Almost arbitrarily shaped channels can be produced by lithography and impression in plastic or metal.
- a plurality of such channels may be provided, or a plate of porous material with open pores, for example of an open-pored sintered material, may be provided.
- the pores have an average pore diameter of 0.1 .mu.m to 150 .mu.m.
- the pore volume is from 1% to 40% of the volume of the sintered body.
- the sintered body may be made of plastic such as polyethylene, polypropylene, polyvinylidene fluoride, or of glass, quartz, ceramic or metal.
- the plate thickness can be from 1 mm to 5 mm.
- the preferably round plate may preferably be tightly inserted into a recess in the bottom of the outer container, for example pressed or glued.
- a permeable membrane containing a plurality of such channels can be used in the form of a film, a woven or a nonwoven, which may consist of a thermoplastic material such as polytetrafluoroethylene or polyetheretherketone or of an elastomeric plastic such as silicone or latex.
- Permeable membranes in the form of a woven or nonwoven fabric may consist of natural fibers, mineral fibers, glass fibers, carbon fibers, metal fibers or plastic fibers.
- a permeable membrane in the form of a sheet of metal - such as Gold, silicon, nickel, stainless steel - or made of glass or ceramic.
- the channels in such permeable membranes may be irregular in shape and made, for example, by ion bombardment or by plasma etching. Further, the channels may be regularly arranged and made, for example, by lithography and impression or by laser drilling; In this case, the many channels within the permeable membrane may be within close tolerances on the shape and size of the channel cross-section and channel length.
- the diffusion-tight outer container is preferably made of a rigid material, for example of metal. Such an outer container facilitates the storage and handling of the double container and protects the inner container against mechanical effects from the outside.
- the pressure compensation device is used for example in a double container, which serves to receive a medical fluid containing, for example, dissolved in a solvent drug.
- solvents for example, water, ethanol or mixtures thereof are suitable.
- medicaments for example, Berotec (fenoterol hydrobromide; 1- (3,5-dihydroxyphenyl) -2 - [[1- (4-hydroxybenzyl) ethyl] amino] ethanol hydrobromide), Atrovent (ipratropium bromide ), Berodual (combination of fenoterol hydrobromide and ipratropium bromide), salbutamol (or albuterol), Combivent, Oxivent (oxitropium bromide), Ba 679 (tiotropium bromide), BEA 2108 (di (2-thienyl) glycolic acid tropol ester), flunisolide, budesonide and others used.
- the pressure compensation device according to the invention is used, for example, in a double container which contains, for example, in the atomizer described in WO 97/12687 the liquid to be atomized.
- FIG. 1a shows a section through the double container before the first removal of liquid.
- the outer container (1) contains the collapsible inner container (2), which is filled with a liquid (3).
- the sampling nozzle (4) protrudes into the liquid.
- the inner container is with its (not shown end) tightly connected to the outer container. Between the two containers is the gas space (5).
- In the bottom (6) of the outer container of the straight channel (7) is attached, which connects the gas space (5) with the environment outside of the double container. This channel is covered with the sealing film (8).
- Figure 1b shows a section through the double container after a part of the liquid has been removed from the inner container.
- the sealing film (8) is shown partially demolished, the inner container is shown partially collapsed.
- Figure 2 shows a section through a further embodiment of the double container before the first removal of liquid from the inner container.
- the straight channel (7) is sealed at its end facing the environment with a pressed-in plug (9). This plug is removed by hand using the loop (10) before liquid is removed from the inner container for the first time.
- FIG. 3 a shows a spiral-shaped channel (11) with a little more than three turns in the outside of the bottom (6) of the outer container (1).
