From welding or the bonding mouth of pipe below by paper tinsel reinforced paper or the paper tinsel film that is fixed in the mouth of pipe must be cut, tear or be squeezed into opening, make passage become unobstructed, liquid or runny material can topple over from container by the mouth of pipe.For this reason, be furnished with a pipe fitting in the mouth of pipe, when cap rotated, this pipe fitting was subjected to axially extruding downwards, and then beginning is rotated along hand of rotation.The pipe fitting lower end is provided with one or more puncturing or cutting teeth.Thus, pipe fitting will cut out a disk from extending the paper tinsel reinforced paper or the paper tinsel film that distribute down at it, and is former because the axial downward movement of described pipe fitting and rotatablely moving subsequently.

Common self-opening closure by one topple over the mouth of pipe, a relevant rotocap and is formed from opening pipe fitting, wherein saidly topple over the mouth of pipe and can securely be installed in a composite packages or, describedly be arranged in and describedly topple in the mouth of pipe and can be configured to move by rotocap from opening pipe fitting by on the container mouth of pipe of paper tinsel film phonograph seal or the bottle mouth of pipe.In up-to-date design plan, to open pipe fitting certainly and have at least one puncturing or cutting element of combination separately, described element is positioned at the lower end of described pipe fitting away from it.It is described that oneself opens pipe fitting, topple over the mouth of pipe and rotocap is provided with induction element and force transmission element, described guiding and force transmission element are fitted to each other by this way, make when rotocap when opening direction and rotate for the first time, at first can in toppling over the mouth of pipe, be subjected to axially pushing downwards and can not rotating from opening pipe fitting, then, described pipe fitting around the rotation of its axis without any moving axially.

Yet, only has puncturing and cutting element of combination separately if open pipe fitting certainly, then pipe fitting must have and the proportional length-specific of its diameter, so do just to make described pipe fitting in toppling over the mouth of pipe, can obtain stable guiding, thereby avoid bevelled to take place really along axial direction.This just need begin closing appliance certainly and have corresponding bottom-to-top-height.In addition, self-opening closure must be designed to comparatively firmly and stable, come from mono-with absorption and puncture antagonistic force with cutting element.Guaranteed the opening first mostly of this closing appliance guaranteed by in the lower end of rotocap one safety seal being installed, this safety seal has several predetermined breaking-downs point, thus, first between installation period, safety seal elasticity is connected on the projection of toppling over mouth of pipe place.When opening rotocap first, must disconnect a lot of independent breaking-downs point simultaneously, need corresponding bigger power like this.

Summary of the invention

The basic function of described self-opening closure is to obtain that a kind of bottom-to-top-height is lower, in fact comparatively flat and simple design, thus, no matter paper tinsel film and inclination situation how, are opened pipe fitting certainly and all can be opened reliably.In addition, self-opening closure needs less plastic material, and is former because it has less bottom-to-top-height.In a specific design, in addition, the user that self-opening closure also should be closing appliance provides that be more prone to realize, guaranteed and opens first.Also should with described open first assurance device be designed to comparatively more flat and more easy, promptly by using less synthetic material.

Described basic function is used for composite packages and is used for being realized by the flat self-opening closure of the container mouth of pipe of diaphragm seal or the bottle mouth of pipe by a kind of; Wherein said self-opening closure is toppled over the mouth of pipe by one, one relevant rotocap and is formed from opening pipe fitting, wherein saidly topple over the mouth of pipe and can firmly be fixed on a composite packages or by on the container mouth of pipe of diaphragm seal or the bottle mouth of pipe, describedly be arranged in and describedly topple in the mouth of pipe and can be by described rotocap rotation from opening pipe fitting, in this, have puncturing and cutting element of a combination from opening pipe fitting, this punctures and is positioned at the lower end of described pipe fitting with cutting element and away from it, described from open pipe fitting within it portion have towards the pipe fitting center, the outstanding spike device that has nail bar and ailhead.The downside of nail bar and ailhead is intended to the guiding piece as the cylindrical wall sections, wherein said wall portion sections is with respect to the rotation axis arranged concentric of cap and be positioned at the inboard of cap, described in addition wall portion sections be formed with a downside with respect to lid be slope profile that acute angle extends and one perpendicular to top surface and with described slope profile bonded assembly thrust surfaces.Relevant special design of opening assurance device first then has argumentation in the dependent claims.

Description of drawings

Accompanying drawing is depicted as the different views of a preferred design of the self-opening closure that is used for composite packages.By means of these accompanying drawings, hereinafter will be described in detail, and its function will be made an explanation self-opening closure.Described accompanying drawing is:

Fig. 1 is in the block diagram of the self-opening closure of disassembled state for its three parts;

Fig. 2 is in the block diagram of the self-opening closure of disassembled state for its three parts, but each parts are carried out the section demonstration;

Fig. 3 is the sectional axonometric drawing that is in the closing appliance of confined state.

The specific embodiment

Figure 1 shows that its three parts are in the block diagram of the self-opening closure of disassembled state, its view direction is downward along diagonal line from the top.Can see that the top among the figure is a rotocap 1, middle for opening pipe fitting 2 certainly, the below is for toppling over the mouth of pipe 3.Rotocap 1 is designed to thread cap, thereby described rotocap 1 is provided with negative thread, and described negative thread cooperates with outside thread on toppling over the mouth of pipe 3.As first essential characteristic, open pipe fitting 2 certainly and have three and be positioned at its lower end and puncturing and cutting element 5-7 away from the combination of pipe fitting 2.These puncture with cutting element in wherein two, that is puncture and cutting

element

5 and 6, be positioned at radially opposite position; The 3rd punctures and cutting element 7 is formed on Zi 85 of the circumference of opening pipe fitting and spends to 100 degree, and punctures and cutting

element

5 and 6 away from other two simultaneously at 8 places, lower end of described pipe fitting 2.

In addition, open certainly that pipe fitting 2 has even layout and along the

spike protrusion

9,10,11 of pipe fitting circle distribution, described

protrusion

9,10,11 is outstanding and have nail bar 12 and an ailhead 13 towards the center of pipe fitting.Effective nail bar 12 of each among these protrusions 9-11 and separately the downside of ailhead 13 for three cylindrical wall sections as guiding and force transmission element, wherein said wall portion sections is arranged with respect to the rotation axis of cap with one heart in the inboard of lid; Described wall portion sections can be seen in another diagram of cap 1.Has an outstanding a little edge 14 in the edge thereon from opening pipe fitting 2, in the outside at described outstanding edge 14, on some specific region of circumference, have breach 29.On the outer wall of opening pipe fitting 2 certainly, be formed with axially extended convex ridge 15-17.These convex ridges and the cooresponding axial convex ridge 18 and horizontal convex ridge 19 mutual actions of toppling over the mouth of pipe 3 inboard places, toppling over the mouth of pipe will be described hereinafter.

Can see and be positioned at the flange 20 of toppling over the mouth of pipe 3 places.Among the figure, an element 21 is positioned at the front side of flange 20, and this element 21 locks onto on the flange 20 by the plug that is positioned on its downside.Flange 20 has the hole that plug passes, and described plug promptly is fastened in the described hole.At these element 21 places, can make three thin material bridge shape 22-24 of portion, the described material bridge shape 22-24 of portion layout parallel to each other, thus at least two exterior material

bridge shape portions

22,24 radially extend with respect to toppling over the mouth of pipe 3.At first, when promptly closing appliance was in installing condition, the lower edge 25 of these material bridge shapes 22-24 of portion and cap 1 linked into an integrated entity.In order to obtain the correct position of rotation of closing appliance, be installed in and topple in the mouth of pipe 3 from opening pipe fitting 2, and then with cover piece 1 together with being fixed on the screw thread 4 of toppling over the mouth of pipe 3 by the material bridge shape 22-24 of portion element 21 formed thereon, then, by being placed in plug clamping element 21 in the hole of toppling over mouth of pipe flange 20, that be positioned at element 21 downsides.

Then, if along opening direction rotation rotocap 1, the then thin material bridge shape 22-24 of portion will at first disconnect, and the wherein said direction of opening is for when the anticlockwise direction when the top is watched, as be positioned at shown in the arrow of cap upside.The mouth of pipe is arranged in parallel and it is radially non-all to be because these material bridge shapes 22-24 of portion is with respect to toppling over, the disconnection at one time of described material bridge shape portion.Material bridge shape portion 24 at first tightens and disconnects, and then is intermediate wood bridge shape portion 23, is only material bridge shape portion 22 at last.Because the material bridge shape 22-24 of portion disconnects by order as mentioned above, thereby needed power is less than the power in institute's employing scheme up to now, and described existing scheme need disconnect many material bridge shapes portion simultaneously.Owing to this reason, in addition more old and also can easily disconnect this assurance device that uses first than the weakling.In a kind of model, can mechanically punch to the intermediate wood bridge shape portion 23 that is radial arrangement with respect to the mouth of pipe, thereby in final closing appliance, when the rotation rotocap, only need to disconnect in turn two exterior material

bridge shape portions

24 and 22.

Among Fig. 2, can see the block diagram of the self-opening closure of its three parts that are in unassembled state.Among the figure, each parts in described three parts show with axial diagram, i.e. axial section.Different with Fig. 1, can see the part of three cylindrical wall sections 26 among the figure, described wall portion sections 26 arranges and is positioned at the inside of lid with one heart with respect to the rotation axis of rotocap.All these cylindrical wall sections 26 have an inclined-plane 27, and this inclined-plane 27 is acute angle by the downside with respect to lid and extends, and a thrust edge 28 perpendicular to the lid downside is connected to described inclined-plane 27.Concerning the combined type closing appliance, when rotocap 1 when anticlockwise direction rotates, this inclined-plane 27 acts on and is positioned on the nail bar 12 of the spike structure 11 of opening pipe fitting 2 inwall places.Identical situation occurs on the inclined-plane 27 of two other cylindrical wall sections 26 equally.Owing to cylindrical wall sections 26 is designed at spike protrusion 9-11, therefore, described wall portion sections 26 can be owing to bending inwardly deflection.This design of being carried out at protrusion 9-11 makes that cylindrical wall sections 26 can be thinner in fact, thus with previous design plan relatively, can design by lighter form.

Be positioned at from opening the guiding convex ridge in pipe fitting 2 outsides and those are positioned at the guiding convex ridge of toppling over the mouth of pipe 3 inboards owing to have, therefore can not rotate and can only axially move down from opening pipe fitting 2.Watch from the top, when making rotocap 1 rotation along anticlockwise direction, thereby described pipe fitting 2 moves down and be subjected to axially downwards pushing in toppling over the mouth of pipe 3, and inclined-plane 27 then slides on the rod member 12 of spike protrusion 9-11, up to thrust edge 28 till nail bar 12 places are subjected to stop.

Thus, open pipe fitting 2 certainly and be subjected to axially downwards pushing, up to its upper limb 14 be positioned at axial convex ridge 18 below.Horizontal convex ridge 19 can be by the upper limb 14 of opening pipe fitting 2 certainly, and is former because the breach 29 that is positioned on this edge faces horizontal convex ridge 19.Certainly opening in the middle of the described axially downwards pushing process of pipe fitting 2, its three puncture and are through it with cutting element 5-7 thorn and extend the paper tinsel film that distributes down.When along unclamping direction when being further rotated rotocap 1, open pipe fitting 2 certainly and further be not subjected to axially pushing downwards, but horizontally rotate.Thus, three puncture with cutting element 5-7 by anticlockwise direction, in the paper tinsel film, cut out a part along the circumferential length of toppling over the mouth of pipe 3, and its anglec of rotation is approximately 120 degree.After roughly carrying out the rotation of this scope, thereby thread cap 1 moves up toppling over further to unclamp on the mouth of pipe 3, make cylindrical wall sections 26 be positioned on the protrusion 9-11, and its thrust edge 28 is not further rotated described protrusion 9-11, thereby is not further rotated from opening pipe fitting 2.Because two puncture and cutting

element

5 and 6 each intervals 180 degree are arranged, therefore when opening pipe fitting 2 rotations about 120 certainly when spending, described

element

5 and 6 stays a slice paper tinsel film along the circumference of toppling over the mouth of pipe 3 and is not cut.The paper tinsel film folds inwardly around described uncut paper tinsel diaphragm just in toppling over the mouth of pipe and keeps being suspended in the opening, can not drop in the package.

Figure 3 shows that the axial section of the closing appliance that is in confined state.Can see among the figure cylindrical wall sections arranged downwards at the lid place of thread cap 1 26 how with spike protrusion 9-11 mutual action, wherein only can see protrusion 11 in the drawings.Starting under the situation of this position, if described rotocap 1 moves along unclamping direction, then the surface 27 of diagonally extending will push the nail bar 12 of adjacent protrusion 11.Can not together rotate with described cover piece 1 from opening pipe fitting 2, thereby be urged downwardly, thus, puncture with cutting element 5-7 and puncture the paper tinsel film that is positioned under it, only can see among the figure puncturing and cutting element 7.This motion is proceeded, and has rotated and axially has been moved upwards up to so position up to rotocap 1, and promptly vertical surface 28 arrives the nail bar 12 of protrusions 11.Owing to axially move down from opening pipe fitting 2, thereby described pipe fitting 2 can horizontally rotate at this moment, and correspondingly, rely on being further rotated of rotocap 1, described pipe fitting 2 is further rotated along anticlockwise direction by thrust edge 28, and described anticlockwise direction is for to watch downwards from the top, thus, puncture with cutting element 7-9 and almost completely cut out a circular piece from its paper tinsel film that early punctures, this circular piece is folding downwards in the ending phase of rotation.

This self-opening closure is characterised in that to have flat especially structure.Being arranged on the described

spike protrusion

9,10,11 of in-to-in along radial direction makes it possible to construct from opening pipe fitting 2 according to light especially and low especially design plan.Also have, the described pipe fitting of opening certainly can obtain the failure-free guiding in the axial direction, former because when rotocap 1 direction of passage cylindrical wall sections 26 down is bonded on the described

protrusion

9,10,11, the rod member 12 and the ailhead 13 of described

spike protrusion

9,10,11 are taken on guiding piece.Comparatively speaking, can make quite lowly with opening pipe fitting 2 certainly, not comprise when puncturing with cutting element 5-7, its height only be 1: 3 with the ratio of its internal diameter, punctures and cutting element 5-7 even count in, and its height also only is 1: 2 with the ratio of its internal diameter.The ratio of whole bottom-to-top-heights and the internal diameter of toppling over the mouth of pipe 3 that comprises block 1, opens pipe fitting 2 certainly and topple over the combined type closing appliance of the mouth of pipe 3 only is 3: 5.Therefore, can produce a kind of very flat pipe fitting of unlatching certainly 2, equally also can adopt less material and correspondingly have less weight, former because described pipe fitting 2 is light thin but multiple functional.
