Technical field
The present invention relates to peel off from skin the laminated peel container and the peripheral technology related of contraction with it along with the minimizing internal layer of interior dress liquid.
Background technology
Laminated peel container is the plastic internal layer of lamination strippingly in plastic outer field inboard, and the neck at laminated peel container is provided with pump and use with being sealed usually.If by this pump interior dress liquid is flowed out from container, then along with the minimizing of interior dress liquid, internal layer will be peeled off contraction from skin.Successfully carry out for the contraction that makes this internal layer, on skin, be provided with the air entrance hole.
As the formation method of this air entrance hole, the skin that has proposed to make laminated peel container is fusion and the method (for example openly putting down into the 6-345069 communique referring to Japanese Patent) of perforate partly.In this method, the internal layer of laminated peel container uses fusing point than outer higher resin material, utilization is set in higher and than the fusion means in the low-melting range of temperatures of inner layer resin than outermost resin fusing point, only makes the outermost resin fusion and forms the air entrance hole.
, the formation method of this air entrance hole exists following problem.
In the very little occasion of heal differential of the fusing point of internal layer and outermost resin, it is extremely difficult only making outer fusion.Therefore, the fusing point of internal layer and outermost resin must have predetermined heal differential, and this is to being used for internal layer and outer field resin choice has produced restriction.
Make outermost resin fusing and when opening the air entrance hole, be difficult to make air entrance hole sharp outline ground to form predetermined shape with the fusion means, must rebuild processing in order to process clean and tidy hole.
For the fusion means are remained within certain range of temperatures, must carry out temperature control, therefore make device complicated.
One object of the present invention is, the method and apparatus of boring a hole into the air entrance hole by the shape of wanting on skin is provided.
In addition, in laminated peel container, a part of bonder outer and internal layer is arranged, openly put down into 4-339759 communique, Japanese Patent as Japanese Patent and openly put down into disclosed in the 5-310265 communique etc.Though about the position that makes the outer junction surface that engages with internal layer all considerations are arranged,, have along the axis direction of laminated peel container the junction surface person to be set by straight line as its a kind of form.
And this laminated peel container is made with following described method usually.
At first, be shaped with the extrusion molding means and have and the lamination parison of the cooresponding lamination structure of laminated peel container that will make or lamination material base (hereinafter referred to as the lamination parison etc.), at this shaping, the junction surface of extending along axis direction is located at preposition, makes and to peel off with internal layer outer with external position at the junction surface.Then, this lamination parison etc. is placed metal die, be configured as the container shapes of wanting with blow-moulding process, and on skin, pass the air entrance hole.
Here, positively flow into, must stagger the position of air entrance hole from the junction surface from the air entrance hole in order to make air.This is because of the occasion that is equal to or less than the width at junction surface at the diameter of air entrance hole, if junction surface and air entrance hole are overlapping, then becomes the blocked state of air entrance hole, and air can not flow between skin and the internal layer, and internal layer is shunk.
, in the laminated peel container of routine, do not have to indicate specially the mark of position, junction surface, wear the air entrance hole with the junction surface overlapping sometimes.
Another object of the present invention is, the laminated peel container that can positively be located at the air entrance hole position of staggering from the junction surface is provided.
And, in laminated peel container, successfully peel off from skin along with the outflow of content in order to make internal layer in use, before the can content, for example as Japanese Patent is openly put down into disclosed in the 6-345069 communique, carry out prestripping and handle.Prestripping for routine is handled, being blown into air forcibly by the air entrance hole from laminated peel container makes internal layer peel off from skin, peel off the back and in container, be blown into air from neck, the air that before was blown between two-layer is discharged from air entrance hole 4, internal layer is restored once more and be adjacent to skin.
, conventional laminated peel container is owing to adopt fusing point to be in 10000kg/cm than outer material height and bending modulus at internal layer 2-50000kg/cm 2In (pressing ASTM D790 measuring method) scope, flexural deformation is little that is elastomeric synthetic resin material, so for the outflow along with content is in use successfully peeled off internal layer, when carrying out the prestripping processing, must peel off fully on whole lamination face.
For this reason, must between two-layer, be blown into the air of predetermined quantity, if regulate error when being blown into then produce the problem that whole lamination face is peeled off fully according to the size of container.
In addition, also exist to have and be used for regulating the control apparatus of amount of air and make the complicated problem of device.
In addition, as is known, in order to make the resin a little less than the outer purpose of peeling off with internal layer must be used connectivity, but in the occasion that laminated peel container extrusion-blown modling is shaped, formed section base portion place's internal layer and skin can not full engagements in the bottom, split under cutting base portion, splitting and form the crack causes seal defect.
Like this, in internal layer as mentioned above, adopt the occasion of the synthetic resin material that flexural deformation is little that is elasticity is high, not only can't overcome this defective, also can further encourage it, when using container, exist when content flows out moisture content etc. from the seal defect intrusion internal layer of bottom and the problem between the skin in the place of humidity.
In addition, in the prestripping of routine is handled, just in container, be pressed into air internal layer is restored once more in case make internal layer peel off the back from skin, but owing to internal layer at this moment is adjacent on the skin, so the rippability of ectonexine is weakened.
Another object of the present invention is, the laminated peel container that provides internal layer easily to peel off from skin also has a purpose to be, provides with the part of little air and peels off with regard to enough simple prestripping method and device.
Moreover, in the prestripping of routine is handled,,, do not see that in appearance what degree the prestripping processing reaches, and checks that it is also very difficult owing to be adjacent to skin in case the internal layer that strips down from skin is restored once more.
Another object of the present invention is, provides easy affirmation prestripping to handle the laminated peel container of the degree of being finished.
In addition, when liquid is poured into container, because interior dress liquid phase is constant substantially for the can of container than generally, thus if container capacity big in upper space after the dress filling liquid also big, the low sometimes below of container shoulder or the upper end of approaching tube portion arrived of liquid level.
Moreover, for the occasion of pump being installed, consider, and the trouble of pump when inserting because the insertion of pump is risen liquid level at the neck of container, have a mind to add the upper air behind the imperial palace dress filling liquid, therefore also make liquid level low sometimes.
Add the upper space after imperial palace is adorned filling liquid like this, liquid level is lower than the neck of container, if near being reduced to a portion upper end from the shoulder of container below, then when conveying container liquid level sway, interior dress liquid shake etc. very fiercely, the result becomes the reason that produces foam or gas according to the difference of interior dress class of liquids.
In addition, if liquid level is low to moderate near the tube portion of container, even then can shown in the interior dress liquid of scheduled volume, for transparent or semitransparent container, also exist from its outward appearance to the customer with the can quantity not sufficient impression of lacking than the those shown.In the occasion of opaque containers, when rocking container in the dress liquid size of shaking also give the same impression of customer.
Another object of the present invention is, the container of the band pump of prestripping method that the capacity of the upper space behind the dress filling liquid in making reduces and the capacity that can reduce upper space is provided.

Prestripping device C comprises as each electromagnetic valve V of control 1-V 5The electrical control gear (not shown) of means of break-make.This control setup comprises two timer T in inside 1-T 2, the position signal the S whether container A of being carried by conveyer with detection is held in a predetermined position 1Being input, is output to indicate the actuating signal of taking out of of container A when the prestripping processing finishes.
Action and the prestripping method of prestripping device C are described with reference to the sequential chart of Figure 14.
Electromagnetic valve V when at first power supply drops into 1Logical, the air that is depressurized is introduced amount of air adjuster 250, and the air with certain pressure is stored a certain amount of.
Follow position signal S 1Input, electromagnetic valve V 1Disconnected, electromagnetic valve V 4Logical, cylinder C 1Piston P 1Descend, when arriving end of run, the 2nd air supply part 230 connects and compresses the neck 204 of container A, travel switch LS simultaneously 1Connect.
Because travel switch LS 1Connect, make electromagnetic valve V 5Logical, cylinder C 2Piston P 2Advance, when arriving its end of run, the nozzle 223 of the 1st air supply part 220 inserts the air entrance hole 210 of neck 204, by the front end extruding internal layer 202 of nozzle 223, peels off while travel switch LS from outer 201 3Connect.
Because travel switch LS 3Connect, make electromagnetic valve V 2With timer T 1Connect, the air of being laid in the amount of air adjuster 250 is introduced between skin 201 and the internal layer 202 from opening 222a, the 222b of the nozzle 223 of the 1st air supply part 220, and the part of internal layer 202 is peeled off, and forms stripping portion 215.At this moment, the front end of nozzle 223 advances along with the peeling off of internal layer 202 around the air entrance hole 210, and the opening 222b of side as shown in Figure 9 is communicated with fully with stripping portion 215.
If timer T 1Time is up, then electromagnetic valve V 2Disconnected, electromagnetic valve V 3With timer T 2Connect, the air of certain pressure is pressed into the inside of container A from the 2nd air supply part 230, the air of previous simultaneously introducing stripping portion 215 is discharged through the 1st air supply part 220 from the opening 222b of the side of nozzle 223, it is outer 201 that the front end of nozzle 223 is retreated into, and makes internal layer 202 attitude that restores to the original state fully.
If follow timer T 2Time is up, then electromagnetic valve V 3With electromagnetic valve V 5Disconnected, the air that is undertaken by the 2nd air supply part 230 is pressed into and stops, and makes cylinder C simultaneously 2Piston P 2Retreat, the 1st air supply part 220 is retreated.
Cylinder C 2Piston P 2Retreat into end of run, travel switch LS 4During connection, electromagnetic valve V 4Disconnected, make cylinder C 1Piston P 1Rise, the 2nd air supply part 230 is moved up.
Piston P 1When arriving the hoisting position of end of run, travel switch LS 2Connect, make electromagnetic valve V 1Logical, while output action signal S 2, container A is handled the position from prestripping takes out of.
As mentioned above, after the container A that has formed air entrance hole 210 is held in predetermined prestripping processing position, by the 1st air supply part 220 prestripping is introduced between skin 201 and the internal layer 202 from air entrance hole 210 with air, a double-ply part is peeled off, then be pressed into air from the neck 204 of container A by the 2nd air supply part 220, the air exhaustion that the previous prestripping of introducing is used, internal layer 202 reinstatement attitudes promptly finish prestripping and handle.
Among the laminated peel container A of this embodiment, be 10000kg/cm owing to the material employing as internal layer 202 has bending modulus 2So the synthetic resin of following flexibility is when using laminated peel container A, along with the outflow of interior dress liquid, from outer 201 internal layer of peeling off 202 shrinkage distortions successfully.
In addition, because only making near the internal layer 202 the air entrance hole 210 peels off from skin in advance partly, so from the outflow initial stage of interior dress liquid, air just successfully flows between skin 201 and the internal layer 202 when using laminated peel container A, peeling off of internal layer 202 can be carried out at an easy rate.
In addition, owing to when prestripping is handled, the part of internal layer 202 is peeled off, so that the amount of air that prestripping is used has is just enough on a small quantity.And, even changing slightly, the size of laminated peel container A also there is no need to regulate amount of air at every turn, operation is easy to.
Though in the laminated peel container A of this embodiment, the air entrance hole is located on the neck 204, also can be located at them in the portion 203.In addition, though, also can bore a hole with the fusion means in this embodiment with beam bear means perforation air entrance hole 210.
(the 4th embodiment)
Figure 15 is the biopsy cavity marker devices front view of the laminated peel container A of the 4th embodiment, and Figure 16 is a birds-eye view, and Figure 17 is a lateral plan.
Laminated peel container A has skin 301 and internal layer 302, is made of tube portion 303, shoulder 304, neck 305 and bottom 313.
Outer 301 is the parts that keep the face shaping of container A, preferably forms with high-density polyethylene resin.
Internal layer 302 is to peel off and deformable inner bag from skin 301, has flexible resin with nylon resin, EVOH (ethylene-acetic acid ethylenic copolymer latex) etc. and forms.
Self-evident, outer 301 are not limited to the resin of embodiment with the material of internal layer 302, so long as it is just passable to have a material of above-mentioned performance.
The skin 301 and the internal layer 302 of container A can be made by the lamination parison blow molding that common extrusion molding is obtained.
On the skin 301 of neck 305, wear air entrance hole 306.This air entrance hole 306 be used for atmosphere introduce outer 301 with internal layer 302 between the hole, be in order to continue to keep the face shaping of container A, successfully to carry out peeling off of internal layer 302, adorn liquid in making and flow out fully and establish.This air entrance hole 306 can be bored a hole with the driling unit of above-mentioned the 1st embodiment.
The upper end of the internal layer 302 in neck 305 is provided with when blow molding the stopper section 307 that the core by the air device for blowing forms.Can stop the sinking of internal layer 302 by this stopper section 307.But the occasion in that the skin 301 and the part of internal layer 302 are engaged with knitting layer also can be provided with stopper section 307.
Near air entrance hole 306, lean against the air that is blown in the prestripping processing, internal layer 302 is peeled off and is inwardly given prominence to from skin 301, forms bellying 309, in abutting connection with this bellying 309 formation spatial portion 308 between skin 301 and internal layer 302.
The explanation prestripping is handled now, and it is that interior dress liquid was being implemented before the container A can that prestripping is handled.
In handling, prestripping uses prestripping device 310 as shown in Figure 18.As shown in Figure 19, prestripping device 310 is perforated out through hole 311 in the inboard, forms nozzle 312 at leading section.
In nozzle 312, be provided with opening 311a that is opened on front end face and the opening 311b that is communicated with the nozzle side, from opening 311b blow out air downwards.
When prestripping is handled, the nozzle 312 of prestripping device 310 is inserted the air entrance hole 306 of neck 305, be blown into the air that a certain amount of prestripping is used, at first the internal layer 302 around the neck 305 is peeled off, then peel off on the top of shoulder 304 and tube portion 303, the internal layer 302 of the part of being surrounded by the line 302b shown in Figure 16 and Figure 17 is peeled off from outer 301, forms bellying 309.
In prestripping is handled,, can form bellying 309 as long as the amount of air that is blown into makes the internal layer 302a that has peeled off bloat the inboard of neck 305 at least.
Though in above-mentioned the 3rd embodiment, make internal layer after skin is peeled off, be pressed into air the prestripping air exhaustion by neck, the internal layer reinstatement attitude of having peeled off is contacted with outer, but in this 4th embodiment, remaining in intact state by the internal layer 302a formed bellying of having peeled off 309.
After this prestripping was handled, with the top observation bellying 309 from neck 305 such as tele camera, whether positively carried out, shift out then if checking that prestripping is handled.
Next adorn the can of liquid in the explanation to this container A.
Though the upper space of container A depends on the can amount of the capacity and the interior dress liquid of container A after the in general interior dress filling liquid, but the interior dress filling liquid of scheduled volume in the container A that as this embodiment, has bellying 309 time, upper space after the can correspondingly reduces by the size of bellying 309, the liquid level La of this moment liquid level Lb when not forming bellying 309 as shown in Figure 18 compares, and the capacity that is arranged by bellying 309 rises.
Because bellying 309 place's hydraulic pressure are very low, even have flexible internal layer 302 to a certain degree conformality is arranged also, even so also seldom discharge of the air that prestripping is used after interior dress filling liquid, even the shape of bellying 309 also keeps after interior dress filling liquid substantially.
When lid was loaded on neck, because atmosphere does not enter in the container A, so prestripping is not discharged from air, it is constant that liquid level La keeps.
Among this embodiment, owing to can be the minimizing of the upper space after the dress filling liquid in the volume controlled of spatial portion 308 by the size of bellying 309, the rise height of liquid level after the can, so by adjusting the amount of air that prestripping is used, even same can amount also can make liquid level rise to neck 305 at an easy rate.
The big person of capacity for container A also is like this.Thereby, though conventionally if the capacity of container A becomes greatly then liquid level drops to neck below 305, perhaps near the upper end of the tube portion 303 of shoulder below 304, upper space after the interior dress filling liquid becomes big, and liquid level sways when conveying container, spumes, but in the container A of the present embodiment that has bellying 309, if by the size of being scheduled to set bellying 309, then can make liquid level rise to neck 305, when conveying container A, can reduce liquid level and sway with interior dress liquid and shake etc.
And, since can after upper space little, the customer container A hand held in the time can obtain sense of fulfillment.
In addition, when prestripping is handled, need be and in container A, be pressed into the operation of air in order to discharge the air that prestripping uses, Fabrication procedure is simple and easy.
And, owing to internal layer 302 is adjacent to outer 301 by in container A, being pressed into air, so the fissility of internal layer 302 can improve when using container A.
In addition, observe, can confirm the state of checking that prestripping is handled simply by neck 305 tops from container A.
(the 5th embodiment)
Figure 20 is the biopsy cavity marker devices front view of the band pump receptacle of the 5th embodiment, and the band pump receptacle comprises and has outer 401 with container body (laminated peel container) D of internal layer 402 be installed in pump E on the container body D.
Container body D at first is described.As shown in Figure 23 and Figure 24, container body D is made of tube portion 403, shoulder 404, neck 405 and bottom 413.
Outer 401 is the parts that keep the face shaping of container A, preferably forms with high-density polyethylene resin.
Internal layer 402 is to peel off and deformable inner bag from skin 401, has flexible resin with nylon resin, EVOH (ethylene-acetic acid ethylenic copolymer latex) etc. and forms.
Self-evident, outer 401 are not limited to the resin of embodiment with the material of internal layer 402, so long as it is just passable to have a material of above-mentioned performance.
Skin 401 and the internal layer 402 of container body D can be made by the lamination parison blow molding that common extrusion molding is obtained.
On the skin 401 of neck 405, wear air entrance hole 406.This air entrance hole 406 be used for atmosphere introduce outer 401 with internal layer 402 between the hole, be in order to continue to keep the face shaping of container body D, successfully to carry out peeling off of internal layer 402, adorn liquid in making and flow out fully and establish.This air entrance hole 406 can be bored a hole with the driling unit of above-mentioned the 1st embodiment.
The upper end of the internal layer 402 in neck 405 is provided with when blow molding the stopper section 407 that the core by the air device for blowing forms.Can stop the sinking of internal layer 402 by this stopper section 407.But the occasion in that the skin 401 and the part of internal layer 402 are engaged with knitting layer can not have stopper section 407 yet.
Near air entrance hole 406, lean against the air that is blown in the prestripping processing, internal layer 402 is peeled off and is inwardly given prominence to from skin 401, forms bellying 409, in abutting connection with this bellying 409 formation spatial portion 408 between skin 401 and internal layer 402.
The explanation prestripping is handled now, and prestripping is handled interior dress liquid was being implemented before container body D can.
In handling, prestripping uses prestripping device 410 as shown in Figure 21.As shown in Figure 22, prestripping device 410 is perforated out through hole 411 in the inboard, forms nozzle 412 at leading section.
In nozzle 412, be provided with opening 411a that is opened on front end face and the opening 411b that is communicated with the nozzle side, from opening 411b blow out air downwards.
When prestripping is handled, the nozzle 412 of prestripping device 410 is inserted the air entrance hole 406 of neck 405, be blown into the air that a certain amount of prestripping is used, at first the internal layer 402 around the neck 405 is peeled off, then peel off on the top of shoulder 404 and tube portion 403, the internal layer 402 of the part of being surrounded by the line 402b shown in Figure 23 and Figure 24 is peeled off from outer 401, forms bellying 409.
Prestripping device 410 is connected with the air feeder that comprises the amount of air adjuster, utilizes above-mentioned amount of air adjuster can adjust the delivery volume of prestripping with air simply in certain scope.
In this embodiment, therefore 406 perforation of air entrance hole when pump E is installed on container body D, are free conductance hand-hole 406 by the effect of lid 420 coverings of pump E on the skin 401 of neck 405.But, also can be located at air entrance hole 406 upper end of the shoulder 404 of container body D, perhaps the suitable position of shoulder 404 or tube portion 403.
Though in above-mentioned the 3rd embodiment, make internal layer after skin is peeled off, be pressed into air the prestripping air exhaustion by neck, the internal layer reinstatement attitude of having peeled off is contacted with outer, but in this 5th embodiment, remaining in intact state by the internal layer 402a formed bellying of having peeled off 409.
The interior dress filling liquid of scheduled volume when this container body D, upper space after the can correspondingly reduces by the size of bellying 409, the liquid level La of this moment liquid level Lb when not forming bellying 409 as shown in Figure 21 compares, and the capacity that is arranged by bellying 409 rises.
Because bellying 409 place's hydraulic pressure are very low, even have flexible internal layer 402 to a certain degree conformality is arranged also, even so also seldom discharge of the air that prestripping is used after interior dress filling liquid, even the shape of bellying 409 also keeps after interior dress filling liquid substantially.
Though be, at first pump E is described with reference to Figure 20 and Figure 26 the pump E container body D of interior dress liquid that has been installed on can like this.
Pump E comprises that by lid 420, inside the cylinder body 421 of piston and valve gear and the operating unit 422 of piston constitute.
The upper end of cylinder body 421 is being fixed and is being had the lid 423 that makes the through hole that piston rod passes, and the top excircle is provided with mounting flange 424.
The lower end of cylinder body 421 is provided with outwards outstanding flange shape sealing 425.Sealing 425 forms when pump E is installed with the inner peripheral surface 405a of the neck 405 of container body D and contacts, so as and neck 405 between maintenance airtight.
Connecting valve seat tube 426 in the bottom of cylinder body 421, sucting pipe 427 and extend downwards from valve seat tube 426.The exhaust tube 428 of dress liquid extends from operating portion 422 in discharging.
Because the inner structure of pump E is a known technology, so the detailed description with reference to drawing is omitted, by means of the pressing operation and the reset force that is contained in the compression spring in the cylinder body 421 of operating unit 422, piston up-down is discharged a certain amount of interior dress solution along with the operation of operating unit 422.
Then, rotating-operation member 422 on lowering position, on lid 423, block, then piston is remained on lowering position, simultaneously the valve member that is located at cylinder body 421 bottoms is fixed in off position, so that stop the flow of liquid that sucts between pipe 427 and the cylinder body 421 when pump E is installed and when not using.
The installation of pump E is identical with general band pump receptacle, is undertaken by lid 420 is fixed on the neck 405, and clips mounting flange 424, the seal ring 430 of cylinder body 421 between the neck 405.
Next the effect of sealing 425 when pump E is installed with reference to Figure 25 and Figure 26 explanation, the change of liquid level.
Figure 25 represents to insert container body D sucting pipe 427 and valve seat tube 426, and the sealing 425 of cylinder body 421 contacts with the inner periphery of neck 405 upper end 405b, the state the when state when container body D is sealed, Figure 26 are represented the installation end of pump E.
When becoming the sealing state shown in Figure 25, the upper space of container body D with install before compare the volume that has reduced the pump parts that insert in the container body D (valve seat tube 426 and suct pipe 427), liquid level L 1Liquid level La (referring to Figure 21) before installing has rising slightly, and ascending amount is suitable with the volume that sucts pipe 427 that inserts in the liquid.
Then, when the state shown in Figure 25 is pressed pump E downwards, sealing 425 descends along the inner peripheral surface 405a of neck 405, up to arriving and air entrance hole 406 cooresponding positions, makes liquid level decline being present in prestripping spatial portion 408 in air exhaustion.
When sealing 425 arrived with the cooresponding position of air entrance hole 406, internal layer 402 was blocked air entrance hole 406, and prestripping stops discharge with air.
In addition, arrive up to sealing 425 between the lower end 405c of inner periphery of necks 405, prestripping is not discharged with air, and just the air in the container body D is compressed.
When sealing 425 left downwards from lower end 405c, the sealing of container body D was removed, and compressed air is by flowing out between cylinder body 421 and the neck 405.
Occasion in air entrance hole 406 formation beyond neck 405, along with pressing of pump E, arrive the lower end 405c of neck 405 up to sealing 425, be present in the prestripping air exhaustion in the spatial portion 408, when sealing 425 leaves downwards from lower end 405c, the sealing of container body D is removed, and prestripping stops to discharge with air.
Sealing 425 arrives after the lower end 405c of neck 405, and when further pressing pump E, liquid level is by rising with the cooresponding amount of the volume that inserts the cylinder body 421 in the liquid, and liquid level becomes L when lid 420 is fixed in neck 405 2
After pump install to finish, because container body D is by secure seal, so prestripping is no longer discharged with air, the upper space of container body D and liquid level kept constant and do not change.
Next, the upper space of container body D and the relation that prestripping is used the amount of air of air are described.
The amount of air of prestripping with air at first is described, as order
Before pump is installed because the prestripping that the prestripping processing charges into spatial portion 408 is Qa with the initial stage amount of air of air,
The air-out amount of discharging from spatial portion 408 when pump is installed is Qb,
The prestripping that remains in after pump is installed in the spatial portion 408 is Qc with the residual air amount of air,
Then set up the relation of following formula between them.
Qa=Qb+Qc
Initial stage amount of air Qa can be by regulating with the amount of air adjuster of prestripping device 410 bonded assembly air feeders.
Air-out amount Qb can obtain according to shape, the size of container body D.
In addition, though the air when pump is installed in the sealed container body D is compressed along with pressing of cylinder body 421, in the be not blocked occasion of post of air entrance hole 406, the distortion of the inner layer 402 of the air in the container body and with the barometric pressure equipressure, the amount of compression of air almost can be ignored.
As order
The radius of the inner periphery 405a of neck 405 is r,
Height from the upper end 405b of neck 405 to air entrance hole 406 is h
Then air-out amount Qb can express with following formula.
Qb=πr 2h
In the occasion of air entrance hole 406 formation beyond neck 405, as order
The radius of the inner periphery 405a of neck 405 is r,
Height from the upper end 405b of neck 405 to lower end 405c is ha
Then air-out amount Qb can express with following formula.
Qb=πr 2ha
In the formula, radius r, height h, ha are the numerical value of the regulation that decides of the design by container body D, so discharge rate Qb is a steady state value.
Though residuing in the residual air amount Qc of spatial portion 408 can obtain according to poor (Qc=Qa-Qb) of initial stage amount of air Qa and air-out amount Qb, but because Qb is a steady state value, so residual air amount Qc can at random set by regulating initial stage amount of air Qa.
Next the pump installation upper space of container body D afterwards is described.
Though the change of upper space and liquid level also can be resolved quantitatively when installing about pump, but because this parsing is very complicated, and detailed parsing also there is no need, so pass through the situation of present embodiment and conventional vessel, with regard to pump upper space afterwards is installed and is compared, can understand the effect of present embodiment.
The volume of upper space equaled to deduct the volume of interior dress liquid of can and volume poor that inserts the pump parts (cylinder body 421, valve seat tube 426 suct pipe 427 etc.) in the container body D from the volume of container body D after pump was installed.
Be provided with the container body of bellying 409 as order, in other words the upper space volume of the container body of internal layer reinstatement attitude is Vo, then because the volume of container body, the volume of interior dress liquid are known, the volume of pump parts is the values that can determine according to its shape and size, so Vo is a steady state value.
As to make the volume of the upper space of the container body D that forms bellying 409 be V, then owing to the volume of interior dress liquid and the volume and the not variation of conventional person of inserting the pump parts in the container body D, so the volume V of the upper space of present embodiment is owing to the existence of bellying 409 reduces, reduction is to be present in the residual air amount Qc that spatial portion 408 interior prestrippings are used air.
Thereby the volume V of the upper space of present embodiment can obtain with following formula.
V=Vo-Qc
=Vo-(Qa-Qb)
In the following formula, because Vo is a steady state value, Qb also is a steady state value, obtains so the volume V of upper space can be used as the amount that changes with initial stage amount of air Qa.
Here, the value of the volume V of upper space is that dress liquid overflowed from neck in negative value meaned, self-evidently must set the Qa that makes V>0.
In addition, setting the occasion of Qa<Qb for, in the process that cylinder body 420 descends, though becoming the moment air till the inner peripheral surface lower end 405c of sealing 425 arrival necks 405 that equals initial stage amount of air Qa when the amount of air of discharging from spatial portion 408 just is compressed, but, because interior dress liquid is incompressible, so the volume of the upper space when pump inserts must deduct the resulting value of initial stage amount of air Qa greater than the volume from neck 405.
Next the action effect of present embodiment is described.
As mentioned above, because initial stage amount of air Qa can utilize the amount of air adjuster of air feeder to regulate, so can be adjusted to the position of wanting to the volume V and the electrolyte level of the upper space after the pump E installation at an easy rate by regulating Qa.
When making initial stage amount of air Qa equal air-out amount Qb, the prestripping in the spatial portion 408 is discharged fully with air, and the stripping portion 402a reinstatement attitude of internal layer 402 can make the released part 402a of internal layer 402 contact with outer 1.
Thereby, in this occasion, be pressed into air to prestripping even in the prestripping treatment process, after introducing between skin 401 and the internal layer 402 with air, be provided with from the neck 405 of container body D, also can when installing, pump make internal layer 402 reinstatement attitudes.
If strengthen initial stage amount of air Qa, the residual air amount Qc that then residues in the spatial portion 408 strengthens, and compares with the occasion of the stripping portion 402a reinstatement attitude that makes internal layer 402, and upper space reduces, and liquid level rises.
If by by predetermined set initial stage amount of air Qa, the volume V of upper space is equal to or less than from the volume of neck 405 deducts the numerical value that the volume of the cylinder body 421 that is present in the pump E in the neck 405 obtains, then can make liquid level be positioned at neck 405 at an easy rate.
Thereby, even the capacity of container body D is big, big and the liquid level of upper space before pump is installed is reduced near the band pump receptacle the lower end of shoulder 404 of container body D, also can after installing, pump make liquid level rise to neck 405 simply, can when conveying container body D, reduce swaying of liquid level, shaking of content stops the generation of foam or gas.
(the 6th embodiment)
The band pump receptacle of the 6th embodiment is described with reference to Figure 27 to Figure 29.
The band pump receptacle of the 6th embodiment and the difference of above-mentioned the 5th embodiment be, is not to establish sealing 425 in the excircle lower end of the cylinder body 421 of pump E, but sealing element is formed on the middle cover F of the neck 405 that is fixed in container body D.
Middle cover F is a synthetic resin system, is made of cylindrical portion 432 that is provided with flange 431 in the upper end and the inwardly outstanding annular seal 433 that is located at the lower end of cylindrical portion 432.
The fitting surface 434 of sealing 433 inner peripherys is adjacent to the excircle of cylinder body 421, plays airtight container body D when pump is installed.
When pump E is installed, at first middle cover F is fixed in neck 405, then the cylinder body 421 of pump E is inserted in the middle cover F.
Container body D was sealed when the lower end of cylinder body 421 cooperated with sealing 433, if pump E is further pressed, then by the volume of the cylinder body 421 that inserts from sealing 433, the prestripping in the spatial portion 409 is discharged from air entrance hole 406 with air.
Owing to be in sealing state in the container body D, liquid level descends when pump E descends, and liquid level is from L 1Become L 2, when but cylinder body 421 arrives liquid level, inserting the volume displaced air-out amount of the cylinder body 421 in the liquid from spatial portion 408, liquid level no longer changes.
After cylinder body 421 pressed lowering position, lid 420 is fixed in neck 405 promptly pump E is installed on container body D.
After pump was installed, because container body D is by secure seal, so the air between air is no longer discharged, the upper space of container body D and liquid level kept constant and do not change.
Next the space, occasion middle and upper part of this embodiment and the relation that prestripping is used the amount of air of air are described.
As order
Before pump is installed because the prestripping that the prestripping processing charges into spatial portion 408 is Qa with the initial stage amount of air of air,
The air-out amount of discharging from spatial portion 408 when pump is installed is Qb,
The prestripping that remains in after pump is installed in the spatial portion 408 is Qc with the residual air amount of air,
Not having the volume of the upper space of container body D after pump is installed of the occasion of bellying 409 is Vo,
It is V (still, the upper space of the occasion of this 6th embodiment is meant the space of sealing below 433 of middle cover F) that the volume of the upper space of container body D after pump is installed of the present embodiment of bellying 409 is arranged,
When pump E was installed on container body D, the length of 421 lower ends was S from sealing 433 to cylinder body,
The radius of cylinder body 421 is r c,
And do not consider the compression of the air in the container body D, then air-out amount Qb can express with following formula.
Qb=πr c 2s
Air-out amount Qb can obtain according to the size of pump parts (cylinder body 421), is steady state value.
Between volume V, the Vo of upper space, same with the 5th embodiment, the relation of following formula is set up.
V=Vo-Qc
=Vo-(Qa-Qb)
In the formula, because Vo is steady state value, Qb also is a steady state value, just changes with initial stage amount of air Qa so have the volume V of upper space of occasion of the present embodiment of bellying 409.
Thereby, also have the action effect same in the occasion of the 6th embodiment by regulating initial stage amount of air Qa with the 5th embodiment.
And, in the 6th embodiment, because middle cover F is fixed in the neck 405, so can further reduce upper space than the 5th embodiment.
As mentioned above, when pump is installed, pump E is fallen when, though liquid level descends the lower end of cylinder body 421 has cooperated till arrive liquid level with annular seal 433 between, liquid level no longer changes after this.
Interior dress filling liquid near the occasion the sealing 433 of middle cover F, though liquid level has rising slightly owing to suct the insertion of pipe 427 grades, but because after this liquid level move very little, so also have can be when interior dress filling liquid the action effect of prediction electrolyte level in advance.
Owing to discharge the interior air of spatial portion 408 by pump E being installed on container body D, so when prestripping is handled, need not be pressed into the operation of air in order to discharge the air that prestripping uses in container A, Fabrication procedure is simple and easy.
In addition, observe, can confirm the state of checking that prestripping is handled simply by neck 305 tops from container A.
In addition, because the upper space of container body D is little, so even do not adorn shaking of liquid in also having in the customer is hand held the band pump receptacle time, the sensation that can enrich to the customer can improve commodity value.
(the 7th embodiment)
The band pump receptacle of the 7th embodiment is described with reference to Figure 30 and Figure 31.
In the band pump receptacle of above-mentioned the 6th embodiment, initial stage amount of air Qa is set less than the occasion of air-out amount Qb (Qa<Qb), liquid level rises along with falling of cylinder body 421 when becoming Qa=Qb, the air in the container body D is compressed.
For the band pump receptacle of the 5th embodiment, because sealing 425 when being located at cylinder body 421 on sealing state when the lower end 405c of neck 405 descends is disengaged, so what problem compressed air does not produce to the atmosphere outflow.
In contrast, in the occasion of the 6th embodiment, because the sealing 433 of middle cover F is adjacent to the outer circumference surface of cylinder body 421, sealing state keeps to the final always, so the air that produces in the container body D is compressed the problem that the pressure in the container body D raises.
In order to avoid this problem, must be adjusted to initial stage amount of air Qa certainly and make upper space for negative value, the means that air is escaped that are compressed also can be provided in addition.
The 7th embodiment has provided the band pump receptacle of the means of this pressurized air escape.
In the pump of routine, as shown in Figure 32, for dress liquid in making flows out at last the narrow groove 421a that carves airiness on the outer circumference surface of cylinder body 421 that has always.Yet concerning conventional pumps, the upper end of groove 421a does not reach the sealing 433 of middle cover F.
In the band pump receptacle of the 7th embodiment, the outer circumference surface that reaches the cylinder body 421 between the sealing 433 as shown in Figure 31 from the lower end of cylinder body 421 at least is carved with narrow groove 421a, with this groove 421a as the pressurized air means of escaping.
Because the fitting surface 434 of the annular seal 433 of middle cover F is adjacent to the outer circumference surface of groove 421a, so though air circulates between cylinder body 421 and sealing 433, interior dress liquid can not circulate because of toughness.
Thereby as Qa<Qb and the air in the container body D when being compressed, pressurized air flows out by groove 421a, and the pressure in the container body D does not rise.
Though in this embodiment, on the outer circumference surface of cylinder body 421, carve narrow groove 421a, also can on the outer circumference surface of cylinder body 421, implement shot-ball peening and form rough surface, constitute pressurized air escape means with this rough surface as the pressurized air means of escaping.
(the 8th embodiment)
The band pump receptacle of the 8th embodiment is described with reference to Figure 33.
Though in above-mentioned the 7th embodiment, on the outer circumference surface of the cylinder body 421 of pump E, form groove or rough surface as the pressurized air means of escaping, but then be on the fitting surface 434 of middle cover F, to establish narrow groove or rough surface 434a in the 8th embodiment, with these as the pressurized air means of escaping.
In this occasion, the advantage that can intactly use conventional cylinder body 421 is arranged.
(the 9th embodiment)
The band pump receptacle of the 9th embodiment is described with reference to Figure 34 to Figure 37.
The 9th embodiment provides pressurized air escape means on middle cover F.
Used middle cover F in the band pump receptacle of the 9th embodiment as shown in Figure 36, comprises flange 431, cylindrical portion 432 and the annular flexible sealing 435 that inwardly projects upwards from the lower end of cylindrical portion 432, and this sealing 435 is adjacent to the outer circumference surface of pump E.
Middle cover F forms with soft synthetic resin, the elastic deformation when pressure of sealing 435 in container body D rises, and front end 435a expansion, and form the gap between the outer circumference surface of cylinder body 421, pressurized air or interior dress liquid can flow out by this gap.
Thereby (Qa<Qb) is so even during the air compression in the container body D, pressurized air also can be from the outflow of above-mentioned gap less than air-out amount Qb because initial stage amount of air Qa set for.
For the 9th embodiment, because flexible seal portion 435 inwardly projects upwards, if set valve seat tube 426 that equals pump E and the volume that sucts pipe 427 for so pump after the interior dress filling liquid is installed upper space before, then liquid level rises to sealing 435 owing to install afterwards at pump, after this liquid level no longer changes, so as shown in Figure 37, have can make at an easy rate in dress liquid be full of the so special action effect in inside of middle cover F fully.
This occasion is even liquid level rises to such an extent that surpass sealing 435 sometimes, as long as quantity is not quite also no problem, because can escape from the gap.
In addition, self-evident in the band pump receptacle of the 7th embodiment, the 8th embodiment, the 9th embodiment, initial stage amount of air Qa is being set greater than the occasion (Qa 〉=Qb), can have the action effect same of air-out amount Qb with the 6th embodiment.
In addition, though in the band pump receptacle of the 5th embodiment to the 9 embodiment, the pump of having represented general type of service as pump E, but be not limited to the pump configuration of embodiment, so long as the part of cylinder block of pump inserts in the container body D, operation by operating unit sucts a certain amount of interior dress liquid and discharges it, all can be contained in the pump among the present invention.
