The specific embodiment

, introduce example system of the present invention and method now according to exemplary but non-restrictive example and referring to accompanying drawing.In following paragraph, different aspect of the present invention is limited in more detail.Each aspect of Xian Dinging can be combined with any others like this, unless clearly illustrate to contradicting.Particularly, any be shown as preferred or favourable feature can be with any to be shown as preferred or favourable further feature combined.

Term " internal depth " refers to the degree of depth of the contact lenses retaining zone in contact lens package, when this packing lies on the plane surface, by from the bottom-to-top-height of the contact lenses retaining zone of this packing, deducting the height of the combination of the relative parietal layer that constitutes this packing contact lenses retaining zone, determine this degree of depth.

Term " sagittal depth " refers to contact lenses and lean against bottom-to-top-height on the plane surface under relaxed state.

Contact lenses are in its " state of equilibrium " and refer to contact lenses and be under the laying state and the constraint of any external force that influences its shape or height of being attended the meeting.

In entire description, term " homogeneity " refers to package wall and is formed by the individual layer of same material (promptly not the layer of layering).Described many packings of being made by the monolayer material of homogeneity also can be made by the multilayer laminated material, and described multilayer laminated material can be formed by the combination of suitable plastic as herein described or the combination of suitable plastic and metal level.

Referring to Fig. 1 and Fig. 2, shown the disposable blister contact les package 1 of typical prior art, it is formed by two parts.Packing 1 comprises blister pack member 2, and it seals by having formed the diaphragm 3 of packing 1 lid, and it can be torn so that discharge wherein contact lenses 4.In Fig. 3, the packing of Fig. 2 is shown as diaphragm 3 and is torn, so that expose contact lenses 4.Typically, parts 2 are preformed blister package, and comprise the recess 5 of moulding, and it provides the recess that wherein can place glasses.Parts 2 generally are injection moldings, and this packing has seal membrane 3, and it matches so that form sterile sealing with flange 6.Contact lenses 4 are dipped in the solution 7 that can keep the glasses hydration, take out from packing up to it.It is very expensive that the performing member of injection molding makes that packing manufactures, the result, and contact lenses will be expensive inevitably for consumers.

Fig. 4 has shown the stacked setting that is used for two identical prior art contact lens packages 10 and 11.As can see from Figure 4, although two packaged conveniences cooperatively interact, their occupied thickness is greater than the thickness (or degree of depth) of these two packings.In theory, consider the reduced size of contact lenses, the glasses packing should occupy as far as possible little space.Key issue when the economy of storage area is the batch manufacturing glasses.The size that existing blister package is formed at glasses has occupied disproportionate space, thereby causes transportation and storage cost to increase.Fig. 5 has shown a plurality of similar blister packages 12, and they are stacked as illustrated in fig. 4 and remain in the carton 13.This volume bigger, inconvenient and glasses packing more material forms exists as traditional technology, this technology represents, glasses are layered in only and can make in the rigid container that glasses and external load separate.

As mentioned above, the preferred embodiments of the present invention provide the non-returnable container that has contact lenses therein, and when contact lenses were in its equilibrium configuration, the internal depth that this packing had was less than total sagittal depth of contact lenses.Some embodiment have adopted the planar materials sheet material of two support components that are sealed or are sealed with between them, and have clearly illustrated such feature, that is, the internal depth of packing is less than the sagittal depth of contact lenses.

In some embodiments of the invention, shown in Fig. 6-9, disposable Contact Lenses packing 18 can be laminated into and make them cooperate each other as stacked spoon.That is to say that when self ground when stacked together, the convex surface of first packing leans against on the concave surface of second packing.The non-returnable container 18 of this embodiment has all first and second sheet materials 14,15 with indenture.Therefore, when non-returnable container 18 sealings, have concave surface and convex surface, and contact lenses are maintained between these concave surfaces and the convex surface.The end face of non-returnable container or bottom surface can be protruding or recessed; Yet in a preferred embodiment, the end face of packing is recessed, and the bottom surface of surface of package is protruding.Stacked being referred to herein as " spoon is stacked " of such disposable Contact Lenses packing 18, and be economical aspect space and the desired secondary package amount.Non-returnable container can be stacked by this way additional embodiments shown in Figure 165.Such non-returnable container can remain on contact lenses a little under the state that flattens, and is in the state of equilibrium, perhaps along the optional position of the continuum between them.Yet the common trait of this embodiment non-returnable container is that they all have such internal depth, this internal depth 0.1 and 3.0mm between, more preferably 0.2 and 1.5mm between, most preferably 0.2 and 0.5mm between.In this case obviously, the definition of the internal depth of contact lens package is existing and should be interpreted as referring to the degree of depth of the contact lenses retaining zone in contact lens package, and the distance between the relative parietal layer of its contact lenses retaining zone by constituting this packing limits.This distance records at the center of contact lenses retaining zone usually.When packing has concavity in the same direction with relative concave surface (for example seeing Fig. 6-9 and Figure 165), should " internal depth " obviously be when glasses are in its normal placement location in packing, the distance between wall on the line that is orthogonal to the glasses center, at contact lens package.Can be by drawing through the line (this line is perpendicular to the glasses face of central spot) at the glasses center in the contact lens package, in package wall and institute setting-out intersection measurement distance, determine internal depth then along this line.Measured distance is the internal depth of contact lens package.

In an exemplary embodiment of non-returnable container of the present invention, as Fig. 6 and shown in Figure 8, the internal depth that non-returnable container 18 is had 0.2 and 0.5mm between, and comprise first sheet material 14 and second sheet material 15 of the material that is sealed.In this embodiment, one of them of two sheet materials 15 has impression 16, and has protruding impression 19.Impression 16 helps to discharge glasses 4, because this can prevent that glasses 4 are from the sheet material 15 that sticks to the band impression, as shown in Figure 8.Therefore, when opening non-returnable container 18, contact lenses 4 are in the predictable orientation.Shown in this alternative 18a of Fig. 7 and Fig. 9, the surperficial 16a of band impression is as alternative and can be positioned on the top-sheet 14a, and it also has recessed impression 19a in this example, and bottom sheet 15a has protruding shape.As shown in Figure 9, the internal depth that contact lens package had is approximately between 0.2mm and the about 0.5mm.Contact lenses stick on the bottom sheet that band does not impress in this example.

Impression 16 can present many kinds of forms, and for example abstract pattern, grid and sign are shown in Figure 10-12.As alternative, Figure 13 and 14 has shown exemplary embodiment, and wherein non-returnable container 18c and 18d do not impress. Sheet material 14 and 15 can be opaque, and is transparent or coloured, for example white or absinthe-green.If sheet material is coloured, then this color can have inwardly towards the contact lenses demonstration, so that can easily see glasses.In addition, sheet material 14 and 15 can have position block letter thereon.This block letter can comprise for example sign (for example literal, chart, figure), prescription, specification sheets and manufacturing information.This block letter can be positioned at package outer, or more preferably, inwardly shows that towards contact lenses (when the package encapsulation) this will increase the visuality of contact lenses.

In another embodiment, shown in Figure 15-17 and 19, non-returnable container 156 comprises the support component 20 that is arranged between sheet material 14 and 14.Support component 20 is enclosed in contact lenses 4 in the non-returnable container 156.Support component 20 can be flexible or rigidity, and can be for example by any suitable polymers polypropylene (PP) for example, polypropylene copolymer (PPCO), polymethylpentene (TPX), polycarbonate (PC), polysulfones (PSF), PEN (PEN), alkene cyclocopolymer (COC), or PEP (FEP) or other materials similar composition.Support component 20 does not change the planar shape of non-returnable container 156.In addition, the thickness of support component 20 is arranged so that non-returnable container 156 still has the degree of depth less than contact lenses 4 natural sagittal depths when sealing.Support component 20 also can be used as shank 21 (Figure 15), so that help to move or open non-returnable container 156.Shank position 21 optionally has otch 24, and it further helps grasping non-returnable container 18, as shown in figure 17.

In another embodiment shown in Figure 180, support component 20a has latticed web frame 22.When glasses leaned against on the web frame 22 in non-returnable container 157, web frame 22 usefulness acted on the additional support of contact lenses 4.Web frame 22 can be made of any suitable polymers material, for example: polypropylene (PP), polypropylene copolymer (PPCO), polymethylpentene (TPX), polycarbonate (PC), polysulfones (PSF), PEN (PEN), alkene cyclocopolymer (COC), or PEP (FEP), or other materials similar.

Have or do not have the non-returnable container of support component 20 can have different shape.For example, non-returnable container can be a square, rectangle, ellipse, circle, tear-drop shaped, eight shape, triangle, and their combination, all these shapes can be symmetrical, asymmetric, straight flange or fillet.Contact lens package 158 and two kinds of other shapes of 159 are shown in Figure 20 and 21.Other shape is acceptable, as long as these shapes can be held soft contact lens.

In other embodiments, shown in Figure 22-45, non-returnable container can have first space 34 that is used for contact lenses and second space 32 that is used for hydration medium.This set can present various structures, and it is flat, spherical that the some of them structure allows second space of hydration medium, and optionally as shank.Figure 22 and 28 shows that second space 32 that is used for hydration medium can be connected first space 34 that is used for contact lenses, and separate by the connection of the seam between two sheet materials that constitute non-returnable container 160 31 in these two spaces.It can be flexible with easily broken connecting 31, and therefore second space 32 can fracture as shown in figure 34, or tears from first space 34, as Figure 22, shown in 28,35 and 36.Second space 32 that is used for hydration medium can have cap 30.Cap 30 can be pulled down by leaving behind, twist or fractureing.As alternative, second space 32 can remain attached on first space 34, shown in the non-returnable container 161 of Figure 24-25.First space 34 and second space 32 can be opened in the identical or different time.In one example, opened before being used for second space 32 of hydration medium in first space 34 that is used for contact lenses.In an alternative example, second space 32 that is used for hydration medium can be opened before being used for first space 34 of contact lenses.First space and second space can be opened by identical or different means.First space and second space 34,32 all can be opened by tear paper tinsel 26 (Figure 28) or other enclosing cover, and perhaps, first space 34 can be opened by the enclosing cover 26 of tearing, and second space 32 can be opened by taking out cap 30.Figure 26-27 has shown that first space 34 opens by tear paper tinsel 26 or other enclosing cover, and second space 32 keeps linking to each other and not opening.

Enclosing cover can seal on matrix, support component, perhaps seals on one of them sheet material that constitutes non-returnable container.Heat-sealing can center on whole periphery, perhaps only around first space that constitutes contact lenses.First space and second space 34,32 can be therein one or both separate before or after opening.In an alternative, second space 32 that is used for hydration medium can be opened by separating second space 32 from first space 34, thereby expose opening or conduit 36 that hydration medium can therefrom overflow, shown in the embodiment of the non-returnable container 162 of Figure 29-34.In another embodiment, first space and second space can be opened by the enclosing cover 26 of tearing non-returnable container 163, as shown in figure 40.Figure 37-39 shows, in this embodiment, two spaces 32 and 34 can be opened by promoting enclosing cover 26 from arbitrary end, and can open simultaneously, perhaps have only a space to open, and another space keep sealing.

Hydration medium can be any solution that is suitable for contact lenses.For example, hydration medium can be again a Wetting Solution, and cleaning solution or any other are safeguarded solution.The example of suitable hydration medium is a brine solution.

In other embodiments, shown in Figure 41 and 116-117, a non-returnable container 164 can be connected on another identical non-returnable container 164 and 182 with 182.The non-returnable container that links to each other can form the band of non-returnable container 41.The quantity of the non-returnable container 164 that links to each other can be between 1 and 90, perhaps between 90 and 180 packings, and perhaps more a plurality of packings.The band of non-returnable container 41 can be the pattern of rolling or be folded into zigzag.The non-returnable container 164 and 182 that is connected together and forms band 41 can only have first space 34 that is used for contact lenses separately, perhaps also can have second space that is used for hydration medium 32.Connection 31 or 76 between the non-returnable container is flexible with easily broken.Also in the embodiment of Figure 41, show, this connection be used to help to open non-returnable container 164 tear breach 40.

The band of non-returnable container 41, perhaps a plurality of single non-returnable containers can be used for the Pop-up distributing box.In this embodiment, a plurality of non-returnable containers 164 are connected with each other via easily broken 31,76 (Figure 116-117) that are connected with 182, and one of primary distribution, make when taking out a non-returnable container 164, can obtain another in the range of distribution of distributing box.Perhaps, a plurality of single non-returnable containers are included in the distributing box by this way, make that this non-returnable container 164 engages with second similar non-returnable container 164 when taking out a non-returnable container 164, therefore can take out this second packing 164 subsequently.

Non-returnable container remains on contact lenses 4 wherein with the state that flattens, and limits the motion of contact lenses 4 when this package encapsulation, and its example is shown in Figure 44 and 67.In Figure 44, non-returnable container 164 prevents that problematic contact lenses 4 from producing motion, and this motion will occur in typical prior art blister package 27.Shown in Figure 46-48, the contact lenses 4 in the prior art blister package 27 can overturn, and the shift position sticks on the side, and doubling occurs.Yet when contact lenses 4 were at first put into packing and sealing, the non-returnable container of some exemplary embodiments just remained on same position with contact lenses 4.In addition, when non-returnable container was opened, contact lenses 4 appeared in the predictable orientation all the time.This makes not too needed glasses are handled before inserting, thereby had reduced that glasses damage or the danger of polluting all appears in people with glasses's glasses and eyes.This also helps contact lenses are put into people with glasses's eyes.Typically, before inserting contact lenses, people with glasses's eyesight has some infringements.Therefore, more usefully, when opening packing, need not see and to know also which kind of orientation contact lenses are in.

Though exemplary contact lens package of the present invention can make contact lenses 4 remain on wherein and it is in the state that flattens or compress,, non-returnable container itself needs not to be flat.Non-returnable container can present different shape.According to an exemplary embodiment, non-returnable container will have elongated profile, and can be stacked compactly and wire up.

Shown in Figure 49 A-51B, the various structures and the configuration that can be used for producing non-returnable container have been shown.In Figure 49 A and Figure 49 B, the non-returnable container 165 of bag type is made up of three layers.Two skins 14,15 are aluminium foil normally, and internal layer is polypropylene or any other suitable polymers.The typical thickness of such non-returnable container 165 is about 1.0mm; Yet this thickness can be smaller, and this depends on the selection and the design of material.Aluminium foil and polypropylene (or any other suitable material) also can be the non-returnable containers 166 that is used for non-bag type, and shown in Figure 50 A and 50B, wherein roughly gross thickness is 1.0-2.0mm, preferred 1.0-1.8mm.In this embodiment, paper tinsel can be simultaneously with acting on enclosing cover and the matrix of packing.Also can produce complete polyacrylic non-returnable container 167, shown in Figure 51 A and 51B, wherein roughly gross thickness is 2.0-3.0mm, preferred 2.0-2.2mm.These structures can be used for producing the non-returnable container that has or do not have spring disk 46 (Figure 61-69), support component 20, can have Any shape or color.For example, other suitable polymers can be used to replace polypropylene, or combined with polypropylene.

Figure 52 has shown another embodiment of non-returnable container 178, has wherein shown the internal depth (" ID ") of non-returnable container.By height and the thickness that deducts outer cover material 47 of measuring packing and the thickness that constitutes the material of matrix 49, determine the internal depth in this packing.In other packing, packing can be provided with the part of the glasses that are not used to remain undetected.When determining the internal depth of contact lenses retaining zone, these parts of packing are disregarded.The internal depth of some embodiment of non-returnable container of the present invention is about 0.1mm to 3.5mm, more preferably 0.1mm to 3.0mm.With size irrelevant be that internal depth is all the time less than the natural sagittal depth of contact lenses under its state of equilibrium.The natural sagittal depth that is in the contact lenses under the state of equilibrium is generally greater than 3.8mm, usually up to 5.0mm.

Shown in Figure 110-113, in an embodiment of the non-returnable container 181 that has polypropylene spring disk 46g, non-returnable container 181 has contact pin 64, and it fractures or disconnect from the main body of packing via hinge 127, so that can open non-returnable container 181.In case the connection between contact pin 64 and the main body makes its disconnection by it is upwards fractureed, then protectiveness enclosing cover 26 can be torn, so that expose contact lenses 4 and polypropylene spring disk 46g.Because the constraint of protectiveness enclosing cover 26 is removed, so polypropylene spring disk 46g just returns back to the arc state of its balance, as the contact lenses on it 4.Therefore contact lenses 4 can be clipped between thumb and the forefinger, and insert in people with glasses's the eyes.In this example, spring disk 46g is a polypropylene; Yet spring disk 46g can be made by various other materials well known by persons skilled in the art, for example any suitable polyolefin, silicone, polyamide, polyurethane or other this licensed material.

In an additional embodiments, non-returnable container 182 is packings of retort type.Referring to Figure 114, shown transparent view according to the non-returnable container 182 of the retort type of an exemplary embodiment.The non-returnable container 182 of retort type comprises the flexible cover of the stratification of the glasses 4 that are used to remain undetected, and it can be formed by a slice or two identical or different flexible materials.According to an embodiment; the non-returnable container 182 of retort type is made by the laminated material of monolithic flexibility; it has enough intensity; so that remain on the glasses in the formed space of packing, but have enough flexibilities simultaneously, so that can tolerate the power that produces because of various loads; such as but not limited to bending; folding, distortion is rolled or extruding.The package wall that is preferably homogeneous material needn't conform to the shape of glasses, but makes glasses " floating " in packing.This " floating " realizes by the fluid force in the sealing gauge of packing, and its crutch glasses also cushions glasses and makes it avoid impact from surface of package.In packing, have little or no air, therefore just farthest alleviated any internal motion.

Can be by the folding also sealing the margin of the material self of homogeneity be formed the non-returnable container 182 of retort type to form aseptic strip of paper used for sealing.Perhaps, can seal along the edge with relative relation, form the non-returnable container 182 of retort type by the homogeneous material of two relative sheets.Separate the non-returnable container 182 of retort type by edge, thereby can get at glasses along one or more predetermined heat-sealings.

In Figure 114, the non-returnable container 182 of retort type comprises first and second barrier layers 14 and 15, and it can form by a folding layer or by two independent barrier layers are combined. Barrier layer 14 and 15 is around edge 66,68,70 and 72 and seal.The heat-sealing of edge 66-72 provides the border, and it defines the inner space 74 that wherein holds glasses 4.Glasses 4 are dipped in the small volume of solution 48 of predetermined kept glasses hydration (seeing Figure 115).In order to discharge and to expose glasses, barrier layer 15 can be torn from barrier layer 14.Perhaps, barrier layer 14 can be torn from barrier layer 15.Discharge barrier layer in order to help to start, the part that engages that matches between these layers is preferably on the corner only sealed a little, so that can separate barrier layer.Figure 115 has shown the non-returnable container 182 of the retort type of Figure 114, and it is torn so that discharge glasses 4.

According to an embodiment, barrier layer 14 and 15 is multilayer layer casting dies, and it comprises the material of following at the legal requirements of glasses packing.For example, non-returnable container 182 materials of representative type retort type can comprise polyethylene terephthalate (PET) layer, aluminium lamination and polyolefin layer such as polypropylene.The aluminium thin layer has such performance, for example intrinsic elasticity and forbid that oxygen sees through, and this makes it become the excellent material that can be used as a barrier wall composite material part.

The non-returnable container 182 of the retort type of preliminary dimension can be formed by the barrier layer of identical or different material.According to an embodiment, can form the non-returnable container 182 of retort type by single piece of material is stacked to from one's body to be formed for keeping the space of glasses to inflection.In another embodiment, the identical or different material of two independent sheets seals on their edge in the mode of relative bonding.According to an embodiment, the lamination of barrier material cuts open skin, 50 microns aluminium lamination and 50 microns the polypropylene layer that type can comprise 10 microns PET.

Get back to Figure 116 now, the band 41 of the non-returnable container 182 of retort type keeps together by easily broken connection 76.The non-returnable container 182 of retort type can once separate one by tearing in seam 76.In addition, band can be folding around seam 76, and this helps efficient preservation and packaging.Therefore can store in the same space of two glasses with adopting prior art blister package 27, store six to eight and the more glasses of possibility.

In Figure 117, shown the band of the non-returnable container 182 of retort type shown in Figure 116, comprise via easily broken connection 76 being connected hydration solution packing 35 on the packing 182.Solution packing 35 can be used by the customer, so that when the glasses hydration that requires to assist, make glasses carry out hydration-treated.

Another embodiment of non-returnable container 201 of the present invention is shown in Figure 166-171.In this embodiment, packing 201 is flat relatively, and this is similar to the packing 169 shown in Figure 67-68, and is made by two laminate materials 202 and 204 sheet materials and spring disk 206.Certainly packing 201 also comprises contact lenses 4 and brine solution (not shown), and can be provided with ornamental block letter and other mark, for example glasses parameter in the outside of front and back.Except being top-sheet 202 and bottom sheet 204 are made by two independent sheet materials, packing 201 can by folding and be modified into shown in the single sheet material of shape make.Spring disk 206 has the diameter of 21mm preferably approximately, the thickness that has about 0.5mm outside in the ring structure, and be that about 0.3mm is thick in the center vane segmentation, wherein about six blade section as shown in the figure, each blade section has many apertures that penetrate.

Packing 201 is designed to peelable, and has the sealing member of tearing that is easy to open, and it has can make the crack force that begins to open packing be substantially equal to the shape that continues to open the required power of packing.Preferred packing is that about 40mm is long and approximately 30mm is wide.The packing preferably make by laminate material 203, can as Figure 171 best shown in.The suitable layers casting die that is used for packing 201 can obtain from the Hosokawa Yoko Co., Ltd of Tokyo as the film that is easy to tear.In an embodiment of laminate 203, have five layers.Internal layer 205 is preferably the leakproofing material that is easy to tear of 35 micron thickness, for example polypropylene.Following one deck 207 is polypropylene films of preferred 15 micron thickness, and it is combined on first polypropylene layer.The 3rd layer 209 is aluminium laminations of preferred 35 micron thickness.The 4th layer 211 is back face printing layers of preferred 3 micron thickness.Outermost layer 213 is pet layers of preferred 12 micron thickness.Certainly, these layers can have different thickness according to different needs, and can use more or less layer.For example, the polyurethane bond material of coextrusion can be applied between the layer 205 and 207, and between the layer 207 and 209.In addition, although the aluminium lamination of 35 micron thickness is preferred,, aluminium lamination can be as thin as 7 microns and thick in 70 microns.Under at least 15 microns thickness, aluminium helps as oxygen barrier layer.Another laminate can have the polypropylene layer that is easy to tear, the binding layer of 35 microns of ground floors, pet layer, another binding layer of 12 microns, 20 microns aluminium lamination, another binding layer and 12 microns last pet layers, and these 12 microns pet layers can be printed before being laminated on all the other films.Binding layer can be the laminate layers of doing.The polypropylene layer that is easy to tear is in the inboard of packing certainly.

In packing 201, be provided with two sealing members.At first, spring disk 206 is sealed in (Figure 167) on the bottom sheet 204 at sealing member 208 places.The sealing part is made into has certain intensity, makes that disk 206 still is attached on the bottom sheet 204 when packing is opened.Top-sheet 202 utilizations are torn sealing member 210 and are sealed on the bottom sheet 204.Tear sealing member 210 fully around disk 206, and the gas tight seal that is used for packing 201 is provided.Sealing member 210 has the given shape that band imports segmentation 212, and it has from the outward extending tip region of sealing member 210 remainders.This point 212 is towards the front side that will at first open 214 of packing.Shown in Figure 169, packing 201 is opened by separating two sheet materials 202 and 204 in the front side 214 of packing.Sheet material (not this means that two front hook unsealings together) in front seal together, therefore easily separates.When top-sheet 202 was stripped from, will being run into and understanding avulsed first of sealing member 210 be the sharp importing segmentation 212 of band.When top-sheet 202 continued to be pulled rearward out, sealing member 210 continued to peel off, thereby had formed opening in the glasses storage compartment.Shown in Figure 169,, tear sealing member 210 and in the zone that imports segmentation 212, separated its width, but the remainder of sealing member 210 remains untouched in this stage.Top-sheet 202 continues to be torn, and arrives position shown in Figure 170 up to it, thereby fully unpacks and expose glasses 4.As other embodiment, when packing 201 was opened, spring disk 206 heart therein ejected, so that glasses 4 are promoted to the position that can easily be taken by the user.

Figure 172 has shown and has opened typical blister package and the packing 201 required application forces figure as the function of time.These figure have shown the power when utilizing the constant speed tension gauge to open packing.The clip of clamping sheet material is with constant speed split movement, and notes applied force.Line 214 has shown the required power of typical blister package sealing for example shown in Figure 47 of opening.When running into leak free first, this power reaches peak value 216.Afterwards, continue to open the required power of packing and descend sharp, and the low district 218 among the arrival figure.Then, if fully take off the lid raw MAT'L, then desired power will arrive second peak value 220.

Peak value 216 and 220 causes because of such reason, promptly, in representative type blister package sealing, the leak free shape is annular (being very similar to the shape that is used for spring disk 206 is sealed in the sealing member 208 on the bottom sheet), and has quite constant radial wall thickness around whole ring.Because lid stock is flexible, so it is stripped from by this way,, has formed the line that moves through package top between lid stock and the point of wherein opening the blister base of packing that is.That opens the required power of packing and this line will be proportional with the length of crossing that segmentation of stripping area.At first, this line will be tangent with the outside of this ring.Yet when package encapsulation began to open, the length of intersection line segmentation increased to maximum apace, and it is the circumference of ring and the function of the radial wall thickness of ring.Very fast, line will move to point, and it has passed sealing and open circuited point, will intersect with sealing in two different conllinear line segmentations now.Yet when packing was further opened, crack force began to descend apace, because the length of the line segmentation of intersecting can diminish near the leak free center time.At that, the amount of the sealing that must open is the twice of the radial wall thickness of sealing just, and this is because sealing is side by side opened in the leak free both sides.Then, when the sealing strapping wires strode across the back side of sealing once more, this application force began to increase once more, and reaches peak value 220.If lid is fully pulled down, power can descend apace certainly, and this is because just can be fewer and feweri at separated sealing area.

The curved shape of line 214 is illustrated in people and attempts to open a prior art blister package practical problems running into of regular meeting often.People must apply very big power and come the first of opening encapsulation to break sealing so that open, if people do not react apace by reducing applied force, then the leak free remainder can break apace, therefore, will overturn and topple over the glasses hydration solution and be included in glasses in the packing if blister package is not held firmly.After the user ran into this situation, they pulled off lid so that opening encapsulation with regard to association in the mode of shaking, so that can more easily control the size of required power.

Use the Hosokawa laminate to add that the combination of the leak free importing segmentation 212 of packing 201 provides improved greatly force curve 222.As can be from shown in the right side of Figure 172, continue 210 required the trying hard to keep of opening encapsulation spare be held in peak force 224 more among a small circle.Peak force preferably can not surpass 150% of the required minimum force of opening encapsulation remainder.Should be noted that the required peak pressure of the opening encapsulation shown in the figure 224 is far smaller than the required peak pressure 216 of unlatching prior art blister package.It is longer that the required time gap ratio of the sealing of unlatching the present invention packing is opened the required time of prior art blister package, and this is that the length of the sealing area on the packing is much bigger because in packing of the present invention.

Opening encapsulation required power be wherein material seal together and adopted heat-sealing sealing area and shape, be used to form the function of the temperature and pressure that sealing applies.Preferred sealing is the pressure that utilizes about 6 crust, and the dwell time in about 1 to 2.5 second and the temperature between 180 and 200 ℃ form.Sealing area 208 and 210 preferable width all are 2mm.

Figure 118 has shown the exploded drawings according to the carton 84 of a large amount of identical strip of paper used for sealing 82 that is used to keep retort type non-returnable container band 41 comprising of an embodiment.Perhaps, described strip of paper used for sealing can keep the non-returnable container 182 of a plurality of independent retort types.Can see from this set, compare that the quantity that can be stored in the glasses in the unit space can be bigger with the packing of prior art.According to the tight ness rating of packing, up to 10, the glasses that may surpass 10 can be stored in the space, and such space was packed and will be taken with two glasses in the past.

The form of the non-returnable container 182 of described retort type will preferably each all comprises a soft contact lens.Suitable technology and legal information can be printed on the outer surface with the similar mode of existing packing.

By the buffering setting around the storage medium in parcel, remain on the integraty of the glasses in the non-returnable container 182 of this retort type.If the glasses packing is subjected to the bigger processing that has the property damaged, then storage medium can be used as safe buffering.Existing blister package by use injection molding, preformed rigidity ship shape part provides the glasses barrier protection.Yet conventional blister package also comprises the aluminium foil enclosing cover, and it is overlapped on opening in the blister package.Compare with the non-returnable container of retort type; the paper tinsel that is supported does not provide other protection; and paper tinsel one side provide may be still less protection, and the non-returnable container of retort type has the two-layer flexible barrier layer that can more desirably react to institute's loading.In fact, the aluminium surface of blister package can be pierced through easilier, because it overlays on the polypropylene ship shape part tightly.The non-returnable container of retort type is softer inherently, and can make possible puncture flexure deformation by moving with the puncture object.

The non-returnable container 182 of retort type allows enough a spot of solution to be used to keep hydration, and does not require that glasses float in the hydration solution as the prior art packing.

In the retort type non-returnable container 182 as contact lens package of the present invention, excessive hydration is kept fluid and can be expelled in manufacturing process, thereby only stays predetermined small volume of solution or gel keeps the glasses hydration.Because therefore the optimal seal quality of the non-returnable container 182 of retort type does not have steam to overflow in the space internally.The planeness of packing barrier layer will help glasses are sticked on one or other inner surface, thereby such advantage is provided, that is, and when layer is stripped from when exposing the in-to-in glasses, glasses will stick on the inside face, and this just guarantees that glasses can not drop out in opening process.

Make disposable glasses and become more and more cost-effective, because the cost of packing glasses has reduced, and the efficient of sealing and sterilization has subsequently improved.Patient will more may be considered as glasses the disposable article in example package of the present invention.In addition, it has occupied littler space, and the mode that can more attract is in appearance packed.Such packing is particularly useful for the disposable glasses of type every day, because one-tenth this part of such packing is all attractive for customer and maker.
