Background technology
On market, have now a large amount of hose bag, but their great majority made by multilayer film, especially such film, they have at least one ply of paper, a plastic layer and an aluminium lamination.These hose bag are comparison pressure-proofs and mainly are constructed to cube.
But the hose bag only made by plastic sheeting recently also appears on market.Especially these hose bag are usually as the again Filling bag of cosmetics.The hose bag of being made by pure plastic sheeting does not have obturator and usually fully in order to take out a part of only cutting away hose bag and the content of hose bag to be emptied in the container, perhaps also have in conversion the hose bag that is made of plastics, they have the flange of a Strip casting mouth mouth and lay a pure spiral obturator thereon.
As mentioning, because hose bag only must be opened and seal once or it is seldom inferior under any circumstance only must to open and seal, so mostly only use spiral obturator.
The plastic-enclosed device that is comprised of the lower member with mouth and lid that is connected through the hinge in lower member obtains with many arbitrarily modification on market, but its installing on hose bag is infeasible.The hose bag that is made of plastics be high flexibility and correspondingly in transportation and in swinging in the larger power of hose bag effect, these power cause the distortion of hose bag and correspondingly improve in pressure.Pure hinge type obturator can not bear these power usually.Therefore, for security consideration, on hose bag, mostly only the plastic-enclosed device is used as pure spiral obturator up to now.
When the container of being made by membraneous material still is closed and people install a beginning when mentioning the closing appliance of type at the container of this sealing fully, the problem that may act on the interior pressure on the obturator does not occur during transportation or carrying.For example have a columniform puncture outfit by the known obturator of WO2004/000667, WO2004/083055, EP1533240, EP1795456 or CH695019, this puncture outfit in the axial direction both sides opens wide and takes that moving part oppositely moves downward in the axial direction and be cut open at this bag film at the sprue gate intra-zone when cover screws off by at least one that covers.In case the film of hose bag is cut open, closing appliance works as simple spiral obturator so.Spiral obturator repeatedly is opened and sealed now during use.In case carry out now really opening of hose bag, it is desirable for that so thus lid can work as swing hinge formula obturator constantly from this.But this is irrealizable in hitherto known obturator.

Present task of the present invention is, changes in this wise closing appliance, so that closing appliance is in the operation of puncture outfit with can or swing the kayser hinge as swing hinge after the opening of hose bag thus and work.
Another task of the present invention is, a kind of closing appliance is provided, it open first and thus after the opening of hose bag not only as swing hinge formula obturator operationally but also, for when should be after opening first the again insurance during the delivery hose bag, operationally be brought in the fixing position as spiral obturator.
Closing appliance with feature of claim 1 solves mentioning at first of task.Closing appliance with feature of dependent claims solves task and other task of secondly mentioning.
Description of drawings
A preferred implementation by theme of the present invention along the sectional elevation of diameter shown in unique figure, and set forth according to following specification sheets.
The specific embodiment
Represent with 1 generally according to closing appliance of the present invention.It is installed on the film of a container B sealing, bag-shaped.This installation is preferably undertaken by ultrasonic welding, but also can be undertaken by bonding.Closing appliance 1 comprises sprue gate parts 2, a columniform puncture outfit 5 and the swing hinge formula obturator 20 as the 3rd parts.
Sprue gate parts 2 comprise a columniform sprue gate 6, flange 3 that radially outward points on the lower edge at this sprue gate is shaped.The cylindrical part of sprue gate parts 3 is referred to herein as sprue gate 6 and is connected integratedly with the flange 3 of mentioning.Sprue gate 6 has a negative thread 8, and puncture outfit 5 that also will describe, columniform leads in this negative thread movingly.In the simplest embodiment, the exterior configuration at sprue gate 6 is threadless.Only in lower area, above flange 3 tight and with respect to the flange almost parallel, extend ground, one around the flange 13 of pulling back outwards point to ground and arrange.The already mentioned negative thread 8 at sprue gate 6 has a rectangular area, trapezoidal moulding.6 upper end is shaped trapezoidal inclination seamed edge obliquely towards the sprue gate, so that puncture outfit 5 do not screwed on when assembling, but can suddenly be pushed into.
Basically the cylindrical puncture outfit that has by the known shape of prior art has an outside thread 7, and this outside thread cooperates with the negative thread 8 at sprue gate 6, and puncture outfit 5 allows spirally to move downward in the sprue gate 6 of sprue gate parts 2 thus.Puncture outfit 5 has a lower seamed edge with its cylindrical wall 11, and this time seamed edge is constructed to cutting edge generally, and has at least one cutting teeth 12, cutting teeth before operating first closing appliance 1, be positioned at the film of container B tight above.On being shaped, the inboard of the cylindrical wall 11 of puncture outfit 5 takes moving part 10 for one.This is taken moving part 10 and comprises an element elongated, that inwardly point to.
On sprue gate 6, lay a swing hinge formula obturator 20 at sprue gate parts 2 in other words.Swing hinge formula obturator 20 is one, but has a lower member 21 and one lid 24, lower member and lid each other by a swing connecting device 22, but preferably mutually be pivotably connected by a tensioning cornice 23.
Lid 24 has a protection face 26, takes moving part 9 for one on the downside of the inside sensing of this protection face is shaped.This is taken moving part 9 and in fact abuts in taking accordingly on the moving part 10 of puncture outfit 5 in its whole length of pointing to from the top down.Swing hinge formula obturator 20 allows with respect to 2 rotations of sprue gate parts.At this, lower member 21 is constant with respect to the axial relative altitude position at sprue gate 6 at least.Lower member 21 has shape locking device 25, corresponding shape locking device 13 mating reactions on it and the sprue gate 6.In the embodiment shown here, the shape locking device on the sprue gate 6 is the already mentioned flange 13 of pulling back.On the lower edge of the perisporium of lower member 21 one around maintenance protrusion 25 be buckled in flange 13 belows of pulling back.Keep being designed to nose at cross-sectional plane in the protrusion embodiment shown here.Swing hinge formula obturator 20 allows thus to be placed to simply in assembly machine on the sprue gate 6 and just in time presses downwards, wherein, in terminal location, keep protrusion 25 from below fasten the flange 13 of pulling back.Swing hinge formula obturator 20 allows thus with respect to sprue gate 6 rotations, and does not change on the whole it with respect to the relative height at sprue gate 6 at this swing hinge formula obturator 20.In rotatablely moving, when rotatablely moving when corresponding direction is carried out, puncture outfit 5 is placed into one and rotatablely moves accordingly by two moving parts 9 and 10 of taking that cooperatively interact.At this, puncture outfit 5 downward spirals and cutting teeth 12 penetrate the film of the container B of sealing itself and open for the first time now hose bag.Puncture outfit 5 is now by downwards spiral is so many, until it is interfered by snapping in accordingly device (they are not illustrated at this), wherein, takes device 9 and 10 and no longer cooperatively interacts for two in this position.When hand of rotation reversed after opening first, puncture outfit remained in its terminal location that is snapped into thus.
Self lid 24 and the lower member 21 of the swing hinge formula obturator relative torsion that has been fixed to resist on the one hand these two parts by swinging connecting device 22 and/or tension band 23 of swing hinge formula obturator 20.Because cover 24 and lower member 21 between torque may be larger, if the user only introduces and rotatablely moves by covering 24, so may be meaningfully, the contact pin 14 of pointing to downwards on the lower edge of lid 24 perisporium is shaped, these contact pin are coupled in the corresponding dead slot 27 in the perisporium of lower member 21.These contact pin 14 can form one simultaneously and guarantee element, and it can be torn after rotatablely moving accordingly.Replace a contact pin and obviously also can expect a plurality of such contact pin 14 that can be coupled in the corresponding dead slot 27.Contact pin 14 also can be arranged in continuously an assurance and be with.
In this particularly preferred embodiment, sprue gate 6 can have an outside thread 30 on its outside a kind of, and this outside thread only exists only in and covers in 24 the zone.Lid 24 has a negative thread 28 here, outside thread 30 mating reactions on this negative thread and the sprue gate 6 at it.
If make again now 20 rotations of swing hinge formula obturator when operating first, lower member 21 does not change with respect to the relative height at sprue gate 6 so, carries out a smaller upward movement but cover simultaneously 24.Relative height between lid 24 and the lower member 21 changes thereupon.Here tension band 23 is tensioned simultaneously.Tension band 23 is now changed into a pure kayser hinge type obturator with pure swing hinge formula obturator.Because in this position after opening first this puncture outfit 5 in a dark position, so now closing appliance open width corresponding to the width of opening at sprue gate 6, in order to be present in the wall of the puncture outfit 5 in this zone before increasing.Thus and because relatively moving of making progress of lid 24, now this lid 24 also can be used as pure kayser hinge type obturator and is operated, and is taking device 9 prevention hunting motions in the shaping at this regularly on the capping 26 of lid 24.Different from the closing appliance of this quasi-tradition, whole closing appliance also designs lowlyer.This is especially because lid all must screw on and screw off no longer forcibly fully at every turn.
After opening first, people only still operate this lid 24 now swingably.But possible is if again seal this container in the state that people are willing to be intended to puncture, and for example to be willing to be intended to carry in the knapsack this container, the swing that can again screw on self by rotatablely moving accordingly so lid 24.This lid 24 plays the effect of simple screw top in fact again now.If people are ready to drink something from container, people must at first carry out screw motion so, move with respect to lower member 21 so that cover 24, wherein, tension band 23 again is tensioned and covers now 24 and again builds effect as the swing of a kayser hinge type obturator.
Obviously, have as the solution of the film hinge that swings connecting device 22 can not with wherein lower member 21 and lid 24 should be combined by the solution that the screw thread 28 and 30 of mentioning is movable relative to each other.
