Definitions

  • the cone of the sealing ring can be lifted from its conical seat in the emptying opening; the sealing gap opens and the mass can penetrate into the space to be sealed between the sealing ring and tubular bag on the one hand and the cylinder space on the other.
  • the mutual centering can also be lost, so that the cone of the sealing ring is not returned to the correct position the next time it is pressed on. Soiling of the device can therefore not be completely avoided by the known arrangement.
  • the emptying opening must be carefully cleaned when changing the tubular bag, because otherwise residues of the mass which may have remained and possibly solidified make a complete seal impossible even during the action of the squeezing force, which then leads to further contamination of the device.
  • the invention has for its object to provide an arrangement of the type specified in the preamble of claim 1, which is less expensive, enables easy replacement of the tubular bag and still ensures an adequate seal.
  • the solution according to the invention consists in the features of claim 1 and preferably those of the subclaims.
  • the exclusive action of the sealing elements of the sealing ring on the end face surrounding the drain opening makes careful cleaning of the less accessible drain opening unnecessary. It is often not necessary to clean the end face interacting with the sealing elements, because experience shows that the mass seldom penetrates so far. Moreover, this area is easier to clean because it is more accessible and easier to control than the wall of the emptying opening.
  • the interacting sealing surfaces place less demands on precise manufacture and assembly, because it is not necessary to match any diameters exactly to one another.
  • the sealing effect is at least as good as in the known arrangement.
  • the invention has the advantage that the seal is independent of the design of the emptying opening and the tubular bag can therefore be used in different squeezing devices.
  • the end face surrounding the emptying opening of the squeezing device is flat.
  • the sealing ring possibly with the exception of protruding sealing elements
  • it has an outer diameter approximately equal to the diameter of the cylinder space. This ensures good guidance and centering of the tubular bag end when it is inserted into the discharge opening.
  • the edge of the sealing ring has a considerable height which, when the tubular bag is inserted into the cylinder space, prevents the edges of the sealing ring prevented. This height is preferably at least 4 mm or 6% (better 10%) of the diameter.
  • the entire or partial circumferential surface is conical or beveled or rounded on one or both edges in order to facilitate introduction into the cylinder space and possibly also to avoid tilting
  • the bag opening formed by a gathering of the bag which projects through the sealing ring and is cut off. According to the invention, this gathering is free in the emptying opening. It is thereby achieved that the gathering, under the effect of the differential pressure, presses more or less against the wall of the emptying opening and forms a seal upstream of the sealing ring there. Even if this may not be perfect, it very significantly inhibits the passage of the mass, so that it often does not reach the sealing elements of the sealing ring.
  • the sealing member or the sealing members of the sealing ring are pressed against the end face of the cylinder chamber by the pressing force exerted by the piston on the tubular bag and are thereby able to fulfill their sealing effect during the pressing process.
  • They can be designed in various ways according to the known principles of sealing technology, in the simplest case the essentially flat surface of the sealing ring or the sealing ring itself forms the sealing element.
  • special sealing elements projecting from its surface can also be provided in any number. They are expediently designed to be resilient so that they move away from the end face formed counter-sealing surface can adjust without gaps. This further reduces the requirements for manufacturing accuracy.
  • the sealing element or the sealing elements can have the shape of one or more circumferential, thin sealing lips. The softness is then given by the thinness of the sealing lip.
  • the sealing ring is provided with an additional, circumferential soft material ring, for example a commercially available O-ring or a ring made of foam rubber with a closed surface.
  • Such an additional ring part can also be a part which is separate from the sealing ring and lies closely against it.
  • This embodiment has the advantage that the part of the sealing ring designed with the tubular bag as a disposable part can be designed to be particularly inexpensive, while the additional ring part having or forming the sealing element can be used several times and can therefore be designed in a correspondingly more complex manner.
  • the sealing ring can be provided with a holding part which locks it in the sealing position according to a further feature of the invention.
  • the invention prefers two embodiments of this idea.
  • the first is characterized in that the holding part is designed as a clamp which interacts with the inner wall of the cylinder space. This is preferably achieved by the fact that the disk forming or holding the sealing ring is flexible and its outer diameter water is a little larger than the inside diameter of the cylinder space.
  • the disc is equipped with a suction holder which holds it on the end face. It can be one or more suction cups.
  • the sealing member is expediently designed as a suction holder. This is the case when a first, inner sealing ring and a second, outer sealing ring enclose a space with the end face, the volume of which is reduced by the compression of the sealing rings against elastic deformation thereof, the compressed air between the sealing rings and the end face is expelled and when the piston force ceases due to the sealing effect of the sealing rings, it cannot easily return into the intermediate space.
  • the sealing rings are expediently designed as sealing lips which point outward from the suction space in order to facilitate the escape of the air from the suction space, but to make it more difficult for the air to re-enter.
  • a braking element at the end of the bag which is opposite the end of the bag containing the opening.
  • the braking element arranged at the rear end of the tubular bag holds the bag in the respective position in the cylinder space. Friction also prevents the bag from sliding backwards or even falling out of the cylinder when the cylinder is removed and placed vertically with the outlet opening upwards.
  • the sealing ring When inserting the bag into the cartridge, it can happen that the sealing ring is slightly crooked relative to the bag axis, for example if the bag is distorted due to deformation due to unskillful handling. This can lead to leaks between the bag and the squeezer.
  • This angular mobility is expediently brought about by the fact that the sealing ring is connected to a disk or is designed as a disk which is glued to the front side of the bag within one of the annular beads facing it, the diameter of which is substantially smaller than that of the bag.
  • the disc area remains outside the ring bulge from the connection with the Bag end face free and can therefore approach it on one side and move away from it on the other, whereby the ring bead forms a kind of tilting bearing.

  • Fig.l shows the tubular bag 1 within a so-called.
  • Cartridge 2 which comprises a wall 3 and a bottom 4. Their inner diameter is dimensioned to match that of the tubular bag 1.
  • Cartridges of this type with tubular bags are used as exchangeable inserts in devices for dispensing plastic materials, for example in devices for dispensing dental multi-component impression materials (EP-A 492 413).
  • the cartridges are inserted into the device so that a device-owned piston 5 can penetrate in the direction of the arrow into the open end 6 of the cartridge which is remote from the floor in order to press out the tubular bag 1.
  • the gathered end 7 of the pouch closed in the storage state at the other end it is cut off so that a bag opening 8 is formed which opens into an emptying opening 9 located in the bottom 4 of the cartridge.
  • a sealing ring 13 is inserted between the end face 11 of the base 4 facing the cylinder space 10 of the cartridge and the shoulder surface 12 of the tubular bag 1.
  • the pressure generated by the piston in the tubular bag 1 also acts on the sealing ring 13 via the shoulder surface 12, so that it forms an effective seal between the end surface 11 and the shoulder surface 12 at least during the pressing-out process.
  • the gathering 7 is pressed against the wall surface of the emptying opening 9, so that a ballast seal is formed at this point.
  • the term cylinder space is not intended to mean that the wall 3 must be cylindrical; however, it is convenient.
  • FIG. 1 shows an example in which the bottom 4 can be detached from the wall 3 in a cover-like manner for inserting the tubular bag 1.
  • FIG. 2 shows that the edge 27 of the sealing ring 13 is drawn up in a pot shape to the side of the tubular bag 1.
  • the height (dimension in the axial direction) of the circumferential surface 28 is increased, whereby a Tilting of the disc-shaped sealing ring when inserting it into the cartridge is avoided.
  • the hollow shape of the edge 27 ensures that the available bag volume is not noticeably reduced despite the increase in the peripheral surface 28.
  • the first embodiment of the sealing ring shown in FIG. 3 is designed as an annular disk 14 which, like the end face 11, is flat. It can be glued to the shoulder surface 12 of the tubular bag 1. Its outside diameter is not significantly smaller than that of the cylinder space 10. When the tubular bag is inserted into the cartridge, it can therefore serve to center the bag opening with respect to the emptying opening. It is made of stiff plastic to perform this task. It also expediently has such a high strength that it can secure the approximately flat or parallel to the end face 11 position of the washer 14.
  • an O-ring 15 (there may also be several) is tightly and preferably firmly connected to the annular disc 14, for example by being glued or clamped into an annular groove. It consists of soft rubber or foam rubber with a closed surface and therefore lies under the pressure acting during the squeezing process without a gap on the end face 11 and thus forms an effective protection against the penetration of mass from the emptying opening 9, if mass between the gathering 7 and the wall of the discharge opening 9 should pass through.
  • the arrangement according to the invention is just as exposed to "breathing" of the device when the extrusion pressure is ended, as known arrangements.
  • the annular disc 14 can, as shown in FIG. 2, be provided with a raised edge 27. 6, the O-ring 15 has moved so close to the emptying opening 9 that it interacts with the edge thereof, which improves the sealing effect.
  • the sealing ring consists of a flat annular disk 16 made of stiff material and glued to the bag shoulder 12 and a layer 17 facing the end face 11 made of flexible material, for example foamed, elastic plastic or rubber with an open or closed surface.
  • the layer 17 is pressed against the end face 11 by means of the annular disk 16 parallel to the end face 11 and thereby causes the seal.
  • the soft layer 17 can be firmly connected to the washer 16, for example formed by a coating provided thereon or glued to it. But it can also be a separate washer, which can be used several times if necessary. In the latter case in particular, it is conceivable that it is designed with such a softness and thickness that it maintains contact with the end face 11 even under the relative movements occurring during "breathing” and therefore seals even at the end of the pressure.
  • Fig. 7 shows a variant of this embodiment with a raised edge of the pane.
  • the sealing ring shown in the third embodiment according to FIG. 5 consists of a tough elastic plastic and is designed as a flat annular disk 18, which can be glued to the bag shoulder 12. Near its inner edge, it has a plurality of annular projections 19 which run around in a ring and have a cross section and are integral with the disk and which form sealing elements on the end face 11. The material is selected and the pointedness of the ring projections 19 is dimensioned such that they can contact the end face 11 without a gap under the extrusion force and in this way form an effective seal. It goes without saying that this pane design can also be equipped with a raised edge 27.
  • the embodiment according to FIGS. 8 and 9 is characterized in that a sealing ring 25 is arranged on the disk 24, which has two elastic sealing lips which are inclined towards and away from the end face 11. If these sealing lips are pressed against the end face 1 under the action of the piston pressure, they deform in the manner as shown in FIG. The space enclosed by the lips 26 and the end face 11 is largely emptied. When the piston pressure ends, the lips form a suction cup which is held on the end face 11 and prevents the lips 26 from being lifted off the end face 11 and thus preventing the movement of breathing and the associated leakage.
  • the sealing ring is each provided with a special sealing member 15, 17, 19. It is understood that the sealing ring itself can also form the sealing member. For example, according to FIG. 1, it can be formed exclusively by a rubber-elastic ring of sufficient flexibility.
  • the edge 27 is greatly enlarged by choosing the appropriate thickness of the disk (FIGS. 10 and 11) or by forming a hollow shape (FIGS. 12 and 13), see above that it prevents the disc from tilting in the cartridge when inserting the tubular bag. So that the disk cannot be inserted from the dispensing side, despite its dimensions close to the inside diameter of the cartridge, its edge on the bag side is chamfered, whereby the chamfer can be limited to the edge area (FIGS. 10 and 12) or can cover the entire circumferential surface 28.
  • the bag 1 is provided on the emptying side with a disk 20 which carries an O-ring 22 near its central opening 21 which allows the bag end to pass through.
  • the outer diameter of the disk 20 is a little larger than the inner diameter of the cartridge wall 3.
  • the disk 20 cannot readily retreat because there is a self-locking friction ratio between its edge 23 and the inner surface of the cartridge wall 3.
  • the seal 22 therefore remains pressed against the end face 11 under the elastic force of the disk 20.
  • this also applies if the self-locking effect at the edge 23 of the disc is dispensed with and only some kind of frictional engagement is provided between the edge 23 and the cartridge wall 3, the resistance of which is at least of the same order of magnitude as that when breathing on the end face of the Bag acting force due to the back pressure.
  • a disc 30 is placed thereon, which contains an opening in the middle for receiving the closure strand 31 of the bag. Their circumference interacts with the inner surface of the cartridge 2.
  • the insertion force is transmitted to the bag via the disk 30.
  • the frictional force on the circumference of the disk 30 therefore does not affect the internal pressure of the bag 1. If the cartridge with the bag contained therein is stored outside the dispensing device and placed vertically with the end 6 downward, the frictional force increases Circumference of the disc 30 the weight of the filled bag 1 and holds it in the existing position.
  • the circumference of the disk 30 can be provided with devices which keep the frictional force in a desired range even in the presence of certain dimensional tolerances of the disk 30 and the cartridge 2, for example with a friction-increasing elastomer ring 32, as shown in FIG. 6.
  • an embodiment which, while opposing the backward movement of the bag with a frictional force of the desired height, offers only less resistance when the bag is inserted into the cartridge from its rear end.
  • embodiments according to FIG. 17 are suitable, for example, in which the plane 33, in which the line of contact between the circumference of the disk 30 serving as the braking element and the inner surface of the cartridge 2, is offset to the rear relative to the main plane 34 of the disk.
  • the friction When the disc moves axially, the friction generates a bending moment on its circumference, which forces the contact area radially inward when the movement is directed into the cartridge, reducing friction, and radially outward in the opposite direction of movement with a corresponding increase in friction.
  • the lip 35 forming the frictional contact can be made of soft material. It can already have the illustrated backward inclination in the shaped, relaxed state; however, it is also possible that the lip lies in the relaxed state in the main plane 34 of the disk and only assumes the inclined position when it is inserted into the cartridge.
  • the circumference of the disk 30 lying against the inner wall of the cartridge 2 need not be continuous; rather, it can be interrupted, so that a plurality of flexible arms are formed, the ends of which resiliently abut the cartridge wall and are connected to one another only in the central region.
  • the axial offset between the contact plane 33 and the main plane 34 of the disk 30 or its arms need not be determined by its original shape; rather, the part can also be designed in a flat manner and only assume the shape bent backwards on the outside by elastic deformation when it is pushed into the cartridge.
  • the diameter of the relaxed disk 30 is larger than the inside diameter of the cartridge, so that the disk periphery or the ends of the arms bear against the cartridge wall with a certain prestress.
  • the deformed bag 1 is inserted inattentively into the cylinder 3, it can happen that the end face of the bag is warped a little obliquely.
  • the corresponding inclined position of the end face is transferred to the sealing ring if the latter is designed as a disk or is connected to a disk which adheres to the end face of the bag over the entire surface is.
  • the sealing effect can suffer if the plane of the sealing ring is not exactly perpendicular to the cylinder axis.
  • the first solution illustrated by FIG. 2 provides that the sealing ring 13 is connected to the bag 1 such that it can move in relation to the bag axis 42. As a result, it can align itself according to its correct sealing position when it is pressed by the bag against the end face of the cartridge base, even if the bag is slightly warped.
  • FIG. 18 shows that the sealing ring, designated as a whole by the reference number 13, consists of a disk 16 and a rubber-elastic O-ring 15 secured in a groove thereof, which cooperates sealingly with the end face 11 of the cartridge base 4.
  • the disc 16 is connected to the end face 12 of the bag 1 by an adhesive and sealing compound 40.
  • the connection is limited to the radially inner region of the disc 16 and the end face 12 and is delimited towards the outside by a bead 41 which is provided in a ring on the end face of the disc 16 facing the bag 1 concentrically with the disc opening and the disc periphery. Outside the annular bead 41, the disk 16 and the bag end face 12 are unconnected and are generally raised slightly from one another.
  • the disk 16 can tilt freely in relation to the bag end face 12 within a certain angular range, the bead 41 being pressed into the bag more on one side and less on the other side. Any skewing of the bag, as indicated in FIG. 2, is therefore unable to affect the position of the disk 16 and the sealing effect of the O-ring 15.
