Fig. 3 is the further schematic diagram according to device of the present invention.Can find out, this container is for upright in this case state.The second anchor fitting 4 comprises a cavity or receives space 62, the pipeline 64 in it, and for the fluid of amount discharge container 10, but also preferred opening.In this case, this pipeline 64 also extends on the longitudinal direction L of container 10.It can further find out, does not want that with the container 10c of this Base body portion wall or the wall of conflicting position, and form in the Base body 10c of container 10.In embodiment shown here, the first anchor fitting 2 is suitable for the bottom construction at container 10.Yet this is not indispensable.
Figure 4 shows that the state of this device when a part for container is drained.In this case, punching body 42 passes container seal 30 punchings, and is incorporated into subsequently the whole cross-sectional plane of described punching body, is arranged in product or fluid F.Within the scope of this, just can make whole anchor fitting 4 or decompressor 4 together with the movement of punching body 42, move downwards.But Zhe Liangge mechanism preferably arranges still.
In this case, the shoulder of movable anchor fitting 2 just can be pressed this container, but particularly preferably, guarantees that the region that is positioned at folding 10e does not have product, unless be only air or gas.
Yet the result of anchor fitting 4 or decompressor is that container keeps the inner support of opening and container shoulder to be kept upright.This can find out, the opening of the shoulder of being not only container that anchor fitting 4 holds, but also comprise region at the beginning.Therefore, anchor fitting should be suitable for the region 4a of the shoulder shape of container 10.When anchor fitting or decompressor are pressed to mirror image shape by this way, the deploying portion of container shoulder is corresponding with the deploying portion 4a of the shoulder of decompressor.Further, the deploying portion of possible decompressor shoulder need to shorten a little, and it more easily will be drawn in outer radial.
As described above, decompressor is anchor fitting 4, and relative motion occurs i.e. the first anchor fitting 2 meetings of support housing.
Preferably, as mentioned above, the first anchor fitting 2 is moved, and by being pressed on static anchor fitting 4.Such advantage is that eduction gear 40 and sleeve pipe can be fixing.
An embodiment of the excessive use of container shown in Fig. 5 10.42 of hole punched devices, just need to be in the punching of the position of respective openings in the situation that of emptying receptacles as far as possible.In this case, the opening of this container arranges downwards.
In the present embodiment, container base 10a is preferably crimped onto in container, thereby also has edge upwards, and in a kind of like this mode, the watermark of product does not produce in edge.In this modification, can emptying resistates very widely.Yet, there is a shortcoming, this container can continue drippage after container 10 is sucked.
Shown in Fig. 6, wherein the first support unit 2 comprises: receiving element, and its shape is suitable for Yi Ge container basic unit, and for example take so-called petal-shaped bottom is embodiment.The present embodiment preferably can stably be supported on the container on anchor fitting 2.
Shown in Fig. 7, according to the further embodiment of apparatus of the present invention.In the present embodiment, anchor fitting 2 does not comprise the receiving device that is suitable for container bottom shape.On the contrary, in this case, container is pressed into different shapes.Therefore, this container is at the first anchor fitting 2 and the second anchor fitting 4, or deforms between decompressor 4 and shell 2.In this case, the pedestal of basic unit and container 10 is with same way in distortion or compression, and little cavity may be left.The plastic material of described container, makes this irregular folding become possibility.In other words, while there is axial deformation, the pressure in container, particularly mechanical compress Neng Shi basic unit and base form suitable shape, to empty in the best way this container.Yet this need to be from the relatively strong compression power of actuating device acquisition and/or sizable gear reduction.
According to the base layer structure of container, their base can be pressed into either large or small shape.Its limiting factor is whether heavy section is at the center of base.And the result of distortion is, the distortion of the shoulder of this container occurs in basic unit or directly above, and this torus section that causes one type is at the center of basic unit, when container unload, and residual direction of flow center there.In this case preferably from the outstanding hole punched device 42 of container bottom.
Another embodiment shown in Fig. 8.Its subsidiary bottom-to-top-height that has reduced this device.In the present embodiment, half length of the second anchor fitting 4 container is also short, for example, in 1/3rd scope of container length.In addition, marked radial circumference projection or flange 48 in figure, this means that not only the mode 10e by fold is indicated on accompanying drawing at container crimping, the region 10g of container also has further minimizing in addition.By this way, as previously mentioned, decompressor length, thus also can reduce bottom-to-top-height.Or rather, it can, by container on length direction L, reduce described the second anchor fitting 4 half length nearly.
In addition, this mode, likely further reduces the amount in container that remains in.In addition, if fluid can, by gas boosting, can further be discharged in container top space.
When container 10 is crimped onto enough deflection wall of container far away, and be positioned on the end or flange 48 of described anchor fitting 4, on the circuit of the another ripple of a ripple starts to be connected from this flange 48.Yet, if wall of container by unbodied compression, it is also no problem.
Fig. 9 is the diagram of an aspirator 40, toward container 10, advances, and more precisely container seal 30.In this case, eduction gear 40 comprises a body 65, and fluid can pass through via this body.Reference numeral 94 represents body, and it is for the end of container seal described in punching.For this object, body or body 64 comprise outer peripheral edges 98, in this case, favour longitudinal direction L location, to penetrate this container seal 30 and region thereafter.
Figure 10 is the figure that its aspirator 40 is introduced in container 10.Can find out, this hole punched device or outer peripheral edges 98 are completely submerged in fluid F.Subsequently, container can be from compressed below, and this fluid can be discharged from container by body 64 or as led to a socket.Described outward flange becomes a part for cutting edge 82.Reference numeral E represents a plane of outer peripheral edges 98 or extends in its plane.In this case, with respect to plane E, longitudinal direction L tilts.
Figure 11 is the schematic diagram of actual punch process.Can find out, in this case, lid 30 or cap 30a consist of elastomeric material, so that bridge joint tapping opening.The pipe 64 of cutting sth. askew is convenient to punching on lid 30.Therefore, the inclination as shown in signal Figure 12, is created a resulting hole of otch and expands.Yet before starting from cap 30a cutting process, the periphery of pipe is sealing completely preferably.The opposite face of radius or marginal portion, blunt portion 84 (referring to Figure 12) regulation, punching middle body (30b) can not become flexible, and finally in container, finishes.Suitably sharp cut edge 82 is essential, and this hole is cut, also without any fiber edge.By this way, such fiber can prevent from finishing in beverage, and other service products.
Figure 13 is by the figure of the sealing member 30 of punching.Can find out, the generation of aduncate sealing member 30c, makes periphery sealed, and is dynamically to seal periphery simultaneously on the one hand.By this way, this will likely make body 64 move forward and backward on specific longitudinal direction, and on request in the peripheral seal of sealing member 30 and tubular body 64, unless be pushed, otherwise can kept state the continuous firing of air seal and Fluid Sealing under the prerequisite that there is no additional seal element.In addition, this will likely apply further sealing arrangement in body 64, such as apply disk on body 64, exerts pressure, or be additionally pressed on sealing member 30, therefore it can increase extra packing element, and for example rubber seal, is for this object.This will further likely improve the leak tightness of container carrier bar 10f.
In fact hanging hole section 30b does not affect sealing yet.
Applicator retains the characteristic right of claims in open application documents, the combination based on feature of the present invention with respect to prior art, there is novelty.
