Description
Technical field
The present invention relates to a kind of for flexible packaging, be the spiral obturator of bag film, it is comprised of the sprue gate with outside thread and attachment flange and the lid with a shell wall and a capping that is screwed on the sprue gate of being arranged on the bag film.
Background technology
The packing, wide-spread such as the spiral obturator of glass bottle or plastic bottle that is used for rigidity.In these traditional rigid packages, spiral obturator only must guarantee sealing function basically in the state of complete closed.This can realize with multi-form sealing member, wherein especially uses such sealing member, the seal to comprise sealing member in the angular zone that is arranged between shell wall and the capping inboard.WO-A-9011944 or WO-A-9011232 and WO-A-9731834 have provided the exemplary of this sealing member.Another type of sealing member on the spiral obturator is so-called " sealing olive ", it is configured the annular wall that the shell wall coaxial line ground of a relative screw top extends basically, and this annular wall is molded on the downside of capping and airtight container or sprue gate on the inboard with pointing to vertically downward.Document DE-A-44 01 751 or US-A-4,253,581 have provided a typical example of this sealing olive.Above-mentioned this combination of two types also is known, for example shown in the EP-A-417554.
In the flexible packaging of bag film form, the sprue gate is made of independent parts, these parts are comprised of tubulose reality, columniform sprue gate, and it has an one-body molded flange thereon, and this flange is used for these parts of spiral obturator are fixed on flexible packaging.For the spiral obturator of this form known in principle two different schemes, namely one be wherein in the zone at sprue gate the film of flexible packaging go out a hole, this hole forms being connected of direct connection with the sprue gate, and wherein flange bonding or welding round this hole of going out.Alternative plan is: bag film fully seals; Reach and on the inwall at sprue gate, additionally be provided with a negative thread, in this negative thread, can instead be provided with axial motion the cutting member of an annular, this cutting member can move by the device of taking on the capping of lid, the screw motion that reaches by lid can make the cutting member motion, this cutting member has at least one cutting teeth in lower edge towards bag film with pointing to, can cut the film of bag film by described cutting teeth.The exemplary of the type is open by CH-A-695019 or EP-A-1795456 and each other different document.
Screw top can be additionally provided with one and guarantee band in the spiral obturator on this bag film of two types.
Because the turning on motion and often need to overcome relatively high friction force of screw top, the user must hold flexible packaging with relatively strong power, and it twists the lid off simultaneously during this period.By this high curable grip the internal pressure in flexible packaging distortion and the flexible packaging will be increased.In case screw top and usually be located between shell wall and the capping in the angular zone sealing member and opened a little, the seal no longer works so.This any problem do not occur on the packing of rigidity, and this is very problematic in flexible packaging, because the user must continue to apply power so that obturator is opened fully, and because described sealing member no longer works now, content is outwards extruded, even ought only extrude little amount, this also be difficult to see, antihygienic and also usually cause screwing up subsequently the adhesion of rear screw formula obturator.
In without the simple spiral obturator that extends in inner cutting member, can consider that in principle extending in the sprue gate enough dark sealing olive by one keeps sealing.But when in a single day spiral obturator is provided with an inner cutting member, then impossible with this class sealing member.Can not make in this respect according to the sealing member of DE-A-39 38 713 and to remedy.Downside at the capping of spiral obturator in this scheme is provided with two concentric annular wall, and they are on the both sides, namely abut against on the sprue gate as sliding seal on inboard and the outside.This scheme has on the spiral obturator of cutting member and can not realize.American documentation literature US-A-4,371,091 provide the scheme of some alienation.Here on the shell wall of spiral obturator above negative thread tight moulding one around the sealing nose, the sealing nose when tightening fully, be in direct contact with in the zone of sprue gate upper limb and can be slightly above this edge to downward-extension.In the situation of this scheme when one very little when screwing the angle sealing member just no longer work, be useless equally for interested here application therefore.Can't make high-precision plastic-enclosed device the sixties in eighties of last century.Yet especially consisted of by the annular seal lip of camber arch and be arranged under the cap face on the side also demanding precision of – at close envelope part – popular on the spiral obturator at that time, in order to especially make its fully demoulding.Propose for this reason a scheme in GB-1205887A, a sliding surface wherein is set in the upper end at sprue gate, the tight feud of ring seal flange above the screw thread leans against on this sliding surface within it on the screw top inboard.Because what relate to here is bottle, the sealing member basically purposes of institute's tool is this obturator of sealing in closed state.Sealing member no longer is in the sprue gate and cooperates after motion is moved in certain screwing, and this is known but also nonessential for bottle.
Its mode of scheme according to DE-1935874U is very similar, but complicated significantly in configuration.Wherein in fact sealing member uniquely no longer works behind circle screwing, but this bottle for relative rigidity also is no problem as mentioned above.
Summary of the invention
Therefore task of the present invention is: a kind of spiral obturator that is used for flexible packaging that starts described type is provided, and what wherein spiral obturator can guarantee still that required tightness to the last turns on fully when the pressure that increasing appears in flexible packaging backs out till the motion.
This scheme both can be applicable to traditional spiral obturator in the case, be that its sprue gate is arranged in the flexible packaging on the already present hole, also especially can be applicable to the flexible packaging of integral asepsis ground sealing, wherein have a cutting member in the inside at sprue gate, this cutting member cuts flexible packaging when spiral obturator is opened.

Fig. 6 be illustrated in the position of opening fully according to spiral obturator of the present invention.
The specific embodiment
Screwed state shown in Fig. 1 when opening a spiral obturator that is arranged in the flexible packaging 1.This flexible packaging can be a stacked carton package, and special tool meaning is a bag film here, as shown in Figure 1.The user holds bag with one when opening bag film 1, and he drives spiral obturator 2 with the another hand-screw simultaneously.At this moment he applies a power F at bag film.By this power the internal pressure in the bag film is raise.If this spiral obturator 2 relates to a traditional form of implementation, then the internal pressure of this rising will cause: liquid can be overflowed between sprue gate and screw cap 5.To adopt remedial measures to this according to the solution of the present invention.
First form of implementation of theme of the present invention shown in Fig. 2.Spiral obturator is generally by 1 indication.It is interpreted as on the one hand being a screw top 5 and being a lower member that is comprised of sprue gate 3 tubulose, cylindrical on the other hand, on the latter's lower edge, forms integratedly a radially-protruding flange 4.On the outside at tubulose sprue gate 3 moulding an outside thread 6.On outside thread 6, can see a threadless section on the sprue gate 3.This threadless section 7 preferably at least be provided with therein outside thread 6 extend axially the identical length of section 8.
Here be provided with in the angular zone between capping 50 and shell wall 51 around sealing flange 54.These sealing flanges 54 form static sealing in the closed state of spiral obturator, and sealing can be born high internal pressure load.
Inside face at lid 5 shell wall 51 forms a sliding seal 10.This sliding seal 10 abuts against on the outside at sprue gate 3 with a predetermined thrust.
Here screw top 5 has been screwed out some in the example shown in Figure 2.If screw top 5 is indicated on the position of tightening fully, then sealing flange 54 will be close on the upper limb at sprue gate 3 and sliding seal 10 will lean against above zone 8 tight of outside thread 6 at sprue gate 3.Can be screwed out such degree at the situation lower cover of arranging like this: just in time the outside thread 6 at sprue gate 3 and the negative thread 52 that covers 5 no longer form and cooperate and sliding seal 10 also leans against on the outside face at sprue gate 3.
Here the selected form of sliding seal 10 is possible configurations in many configurations.Important only is: sliding seal with certain deformation force by pasting.For demoulding sprue gate 3 must have certain adaptively, so that the internal diameter of upper edge is slightly less than the internal diameter in the zone of flange 4.The wall thickness at sprue gate 3 also is that zone from flange reduces a little towards upper limb in addition, thus sprue gate 3 always in threadless section 7 a little taper ground extend and sliding seal 10 must can be followed this tapering and in uppermost zone still with certain thrust by subsides.
Because the assembling of screw top is problematic when sliding seal is inwardly stretched too much, the Shi shown in replacing here execute Xing Shi – sliding seal in this form of implementation have one around ground downward, namely also can be significant with the tip of its flexibility towards the Gou Xing – of the pad of flange.In conversion we also can with sliding seal more unfertile land consist of so-called sealing lip, itself can receive less power.In the case we will preferably arrange a plurality of like this around sealing lip.In fact these sealing lips for example can vertically arrange with the shell wall inboard, and in the automatic camber arch up of these sealing lips of when assembling.This has very large advantage, and the internal pressure that namely acts on the sealing lip is pressed on the sprue gate sealing lip with strengthening.A plurality of sealing lips such as in fact also play at the same labyrinth sealed effect in addition.Although therefore this here not the Hou Du Bao – of these sealing lips of Fang An – of going out of formula can keep high internal pressure.This screw top deviating from from injection mould is debatable in principle.Yet this technology is known for a long time, namely we at first will cover and take out and then pull out fully the fuse that stretches into lid inside from mould for this screw top, at this moment outwards springing of shell wall, so that when pulling out fuse, no matter be that negative thread 52 or sliding seal 10 all remain unchanged, can be damaged.
A spiral obturator 2 in the flexible packaging 1 also is shown in Fig. 3-6.Sprue gate 3 and flange 4 thereof do not change except a negative thread 22.But in sprue gate 3, supporting foregoing cutting member 20 screw motion.The device 23 of taking that is located on the cutting member inside face is used as one second backstop of taking device 24, and this second capping 50 of taking device and lid vertically stretches to the below.Its outside thread 25 that moves in the negative thread 22 at sprue gate 3 of cutting member 20 usefulness down moves and cuts film F open by at least one cutting teeth in the case when outwarding winding screw top 5.And in this scheme, also be provided with a sliding seal 10 as the front is described by Fig. 2, this sliding seal can be clear that in Fig. 6.Especially in this form of implementation, can be clear that: can not realize sealing member in the inboard at sprue gate here.Yet described above, in fact do not change ground – according to the solution of the present invention also fair – that permitted and use on this scheme of spiral obturator.
– is with 40 as being additionally provided with an assurance according to a sample ground – screw top in the scheme of Fig. 2 in this scheme, but this assurance band shape be arranged in locking manner below externally threaded on the sprue gate 3 one around the back of ring 30.Assurance is molded on the lower edge 55 of screw top 5 by given breaking-down point bridging part 41 with 40, guarantees to be with 40 to be torn and reservation is suspended at below the described ring 30 when turning on.This state is indicated on the right side among Fig. 2, represent then that on its left side a kind of assurance is with 40, although it similarly catches ring 30 in the back, this assurance band will for example remove by a sheet, at this moment makes to guarantee that the given breaking-down point bridging part that band is connected with screw top will disconnect.Given breaking-down point bridging part represents with 41 in the accompanying drawings.Yet these given breaking-down point bridging parts only represent with the form that disconnects, on the one hand as guaranteeing with the stump on 40 and on the other hand as the stump on the lower edge 54 of screw top 5.
Can realize in this wise also according to the solution of the present invention that in principle namely we are not arranged on sliding seal and cover on 5 the shell wall 51 and be arranged on the outside at sprue gate.Can consider in the case two schemes, directly be arranged on the top of screw thread namely or with sliding seal or be arranged in the zone of upper limb at sprue gate 3.Then must be configured relatively longly at the situation lower slider sealing member of the first scheme, seal in order to can surmount the out-of-flat of screw thread.Situation lower slider annular seal at alternative plan can radially extend shortly and therefore also can consider a plurality of sealing lips here, and the slip ring seal of preferred pad form is more meaningful in the situation of the first scheme.
