Definitions

  • the present invention relates to a cap for sealing a cartridge, designed for paste compounds, according to the preamble of claim 1.
  • the invention also relates to a method of applying , using and affecting respectively the cap mentioned in claim 1 and a tool respectively for affecting the cap mentioned in claim 1, according to the first claims in these claim groups.
  • Such cartridges are widely used for e.g. lubricants and silicones. They are placed in a tool, which looks like a pistol, in which a piston stem with a disc is pushed against a cap in the bottom of the cartridge in order to discharge the material from a spout at the opposite cartridge end.
  • DE-C-4 229 588 which relates to a cap having a concave bottom, which, when the cap is inserted by means of an insertion tool, is turned out forwards in order to give it a convex shape with a simultaneous reduction of the diameter of the cap, to make it possible for entrapped air to flow backwards between a lip, which surrounds the free end of the cap, and the inner wall of the cartridge.
  • the comparatively pronounced turning out which is a prerequisite for entrapped air to be, with any considerable reliability, able to be discharged, involves a relatively thin-walled cap design, which is deleterious for a subsequent efficient and reliable material discharge.
  • the cap design In order to achieve this the cap design must be relatively stiff, which however in its turn would not allow a strong turning out without being damaged. 2
  • DE-A-3 005 855 which relates to a cap with an advantageous design, as regards stiffness and consequently also reliable discharge properties.
  • this cap does not , in addition to claimed self-aeration properties of this cap design, allow a removal of air entrapments.
  • DE-C-4 229 588 the main purpose of which is to "render possible an air-free insertion of the piston after the filling of the compound" (column 1, lines 56-59).
  • DE-A-3 005 855 does not allow, in immediate connection with the discharge of the material, a return suction of a small amount of material from the spout and consequently also not a prevention of double draining of material.
  • DE-C-4 139 744 which mainly is characterized by an insert, which in order to make it reusable can be removed from the cartridge after the discharge of the material.
  • the cap has a convex shape, but it has no means at all and no satisfactory means respectively designed to prevent air entrapments and return suction of material from the discharge end and residue discharge respectively. The same is true in the EP-C-0 081 145- case.
  • US-A-5 316 186 relates to a cartridge, the object of which is a most complete residue discharge of the contents in the cartridge.
  • a cap is provided with a pin, which penetrates the cartridge spout in the final phase of the discharge, which pin can be inserted into the cap as a loose part in order to i.a. allow a discharge of entrapped air, when the cap is inserted into a filled cartridge.
  • a particular tool (rammer 10, Fig. 8b, col. 5, lines 22-25) is designed to create an air discharge path via a temporary opening between a pin bead and the bottom opening of the cap for the pin.
  • the bottom must, for this purpose, be relatively thick and stiff in order to be able to transfer a pressure, exerted on the peripheral area, to the central part, where said opening is formed.
  • a plurality of concentric ribs arranged inside the cylindrical piston wall, reinforces the stiffness of the piston bottom, which counteract the risk of a return suction of a limited amount of the contents in the cartridge in connection with a discharge procedure. Such a return suction is on the whole neither shown nor mentioned in this document. 3
  • US-A-5 083 416 relates to a method and a device designed to insert a cap in a tube, the cap being folded by means of a pressure element, inserted into it from behind, which element is shaped like a fork and folds the cap in two diametrically opposed places to allow the discharge of entrapped air backwards past the cap.
  • a pressure element inserted into it from behind
  • element is shaped like a fork and folds the cap in two diametrically opposed places to allow the discharge of entrapped air backwards past the cap.
  • this folding two in the circumferential direction quite limited, mainly dot-like areas are pressed inwards, whereas the rest of the peripheral areas of the cap are pressed outwards and reinforces the abutment pressure against the tube wall within said areas, an air discharge within these areas being actively counteracted.
  • the object of the pesent invention is to counteract and as far as possible remove the above- mentioned drawbacks as well as to develop a new cap and a new method of attaching, using and affecting the same , which allows a simple, quick and reliable removal of air entrapments and simultaneously allows the discharge properties of the cap to be made and remain optimal, including a complete and satisfactory respectively residue discharge and including a limited desired return suction of material from the discharge nozzle of the cartridge, when the discharge is interrupted. Also, the design of the cap and the tool respectively must allow a recovery repeatedly without limitation and without quality reduction.
  • a double-action piston for the discharge of the material is obtained, namely a primary piston, which comprises the cylindrical support ring and the bottom portion, which closes it, whereas all around this bottom portion and the support ring the rest of the cap portions exert 4
  • the primary piston protion is principally designed to carry out the discharge of the material and remains essentially stiff during the discharge, whereas the secondary piston portion to a limited extent is flexible and carries out a return suction of a certain amount of material in connection with a discharge phase by, during the discharge, change its shape and in connection therewith, due to its inherent resilience or structural elsticity, recover its original shape.

  • a tool 1 which looks like a pistol and comprises a shell 2, designed to recieve a cartridge 3, and a feed mechanism 4 with a piston stem 5 and a disc 6 at its free front end.
  • This tool is well-known and thus will not be described in detail, but it is worth noticing, that the tool preferably ought to have an independent, somewhat returning motion of piston in connection with a discharge step in order to achieve a decompression by means of disc 6.
  • Cartridge 3 mainly comprises a cylindrical tube 7 having e.g. a discharge spout 8 at its front end 9, rear end 10 of the tube being open and designed, subsequent to a filling of a paste compound 11, e.g. a lubricant, a silicone or the like, to be closed by means of a piston cap 12.
  • a paste compound 11 e.g. a lubricant, a silicone or the like
  • Cap 12 is according to Figs. 1-8 , like the tube, made of a plastic material and has a mainly circular cylindrical wall 13, from the exterior side of which sealing lips 14 project, which preferably have a triangular cross-section, obliquely point backwards and are placed all around this wall.
  • Rear end 15 of the wall can comprise or be provided with an extension 16, which obliquely points backwards and runs all around rear end 15 and can have a somewhat larger diameter than said lips and can have a corresponding profile with a sharp free edge 17.
  • Said extension has at its interior side a bevel 18, which facilitates the introduction of a tool, to be described below, and the above-mentioned piston stem 5 and its disc 6 respectively.
  • Front end 19 of cap 12 has a flange 20, placed almost within a radial plane all around the end and having a width, which is approximately 10 % of its outer diameter, and a thickness, which is roughly twice as large as the thickness of wall 13.
  • the flange preferably projects somewhat beyond the outer side of the wall, but it is mainly placed inside the inner side of the wall. It preferably is oblique backwards to some degree and its free end side 21 suitably is slightly concave in order to form a sharper free front outer edge 22 than what would otherwise be the case, e.g. in case two surfaces meet each other with an angle of 90°.
  • To inner edge 23 of flange 20 a concave bottom 24 with a partially spherical shape is connected.
  • the depth of the bottom can in a practical example be about 20 % of its diameter.
  • the bottom sutiably has about the same thickness as the flange and is on its rear side 25 provided with a centrally situated circular cylindrical support ring 26, which projects axially backwards 1-10 mm, preferably about 3 mm and the diameter of which is 5-30 mm, preferably about 10 mm, in a practical embodiment.
  • a lip 27 projects all around from the rear side of the flange and the area between its inner edge and wall 13 obliquely inwards and backwards, which lip in its cross-section slightly narrows, namely to about 50 % at its free edge 28 as compared to the shoulder thickness.
  • the angle between the oblique annular lip and the flange is about 60° and thus the angle between the annular lip and wall 13 is about 30° .
  • the free edge of the oblique annular lip is situated on a level above the shoulder of the support ring and preferably also above the deepest central part of the bottom.
  • a tube 7 has been filled with a paste compound 11 and a cap 12 has, by means of not shown but already known machines, been introduced into rear tube end 10, an air- filled space 29 having been locked in.
  • the latter and bevel 32 have about the same conicity, i.e.
  • bevel 32 does not in this first contact position abut the entire length of the oblique annular lip but only roughly the rear half, but there is an opening 33 all around between the inner side of the cap wall and the outer side of the tool, which side within the area of the bevel 32 preferably consists of an outer bevel all around or a rounding off 34, which will start functioning in the next phase, when the tool is pushed forward according to Fig. 3 in order to completely penetrate and fill the wedge-shaped slot 35 between oblique lip 27 and the inner side of cap wall 13.
  • the cap wall which is connected to the flange, is then bent somewhat around the outer bevel or rounding off 34 of the tool, which bevel or rounding off also makes the length of the tool shorter and consequently makes the length of its insertion distance after the initial contact longer (Fig. 2).
  • a ring-shaped gap 36 is created between inner side 37 of the tube wall and flange 20 as well as the outer side of the cap wall, which means that air, which has been entrapped in space 29, is able to flow out backwards through this opening around the flange and the outer wall of the cap, while said space is obliterated by the forward movement of the cap.
  • the tool In connection with the compression and the advancement of the cap, which take place within a fraction of a second, the tool is withdrawn and the cap occupies a position, in which the bottom again is bent in the normal way according to Fig. 4, in which the filled cartridge is to be used by an operator, who has put it in a tool 1 with piston stem 5 and disc 6 situated in cap 12 close to support ring 26.
  • the free end side 21 of the flange is vertically or slightly backwardly tilted in relation to the cartridge wall.
  • the bottom is influenced by this pressure with a certain bending radius increase, i.e. the bottom is made more even, the flange 20 being tilted somewhat stronger backwards and directed, with its free outer edge 22 more accentuated and with a stronger pressure, against the tube wall due to the fact, that the bottom is made more even, which means, that the diameter of the cap increases within this area.
  • the cap wall close to the flange functions as a hinge. Since the tilting is small and only includes a few angular degrees, it can be arbitrarily repeated many times without damage to the material and the shape of the cap.
  • the oblique annular lip 27 has an additional task, which is made clear when considering the transition from Fig. 6 to Fig. 7.
  • the support ring has initially been completely pushed forwards in order to fill in the front, suitably slightly conical cartridge end with a changing of the bottom from a concave to a convex shape, while the oblique annular lip has been pushed forwards to obtain a completely even shape, which is tantamount to a durable deformation, which however is not important, since the cap, besides a possible material recovery, does not have any additional task to fulfill.
  • Fig. 7 shows, that the bottom area between the support ring and the oblique annular lip has been pused forwards to a plane abutment against the front cartridge end wall. This is possible thanks to the inherent resiliency, which connects the lip and at least a roughly comparable large portion of the bottom.
  • Cap 12 has at its front end 19 a flange 20 all around, almost situated within a radial plane, with a width, which is approximately 5 % of its outer diameter, and a thickness, which is approximately twice as large as the thickness of wall 13.
  • the flange preferably projects somewhat beyond the outer side and the inner side of the wall. It preferably slants a little rearwards and inwards or outwards, i.a. in order to facilitate a contraction, to be described later, and its free end side 21 suitably is slightly concave in order to form a sharper free front outer edge 22 than what would otherwise be the case, e.g. in case two surfaces meet with an angle of 90° between them. Said slanting can also result in a sharper edge.
  • Inner edge 23 of flange 20 is via a slot 38 connected to a convex bottom 24 having a roughly partly spherical shape.
  • the depth of the bottom can in a practical embodiment be about 10 % of its 9
  • the bottom suitably is somewhat thinner than the flange and is on its rear side 25 centrically provided with a circular cylindrical support ring 26, which projects about 8 mm, and the diameter of which is 5-50 mm, preferably about 20 mm, in a practical embodiment.
  • the support ring is designed with relatively thick walls, e.g. having about the same thickness as the flange or twice the thickness of wall 13, which will make the support ring relatively shape resistant, also when the pressure exerted by disc 6 is large.
  • the diameter of the support ring preferably is roughly half of the diameter of the cap.
  • a bottom portion all around projects from the inner edge of the flange and the bottom area outside support ring 26 obliquely inwards and backwards, which forms a slot 38, which in its cross- section preferably is roughly V-shaped and is open forwards or outwards and has walls 27 and 27 ' .
  • Wall 27, which is the outer one in a radialdirection, is in this cross-section suitably somewhat thicker than wall 27 ' , which is the inner one in said radial direction and which suitably has roughly the same thickness as wall 13.
  • the angle between outer wall 27 and the flange is about 45° and thus the angle between outer wall 27 and wall 13 is also about 45°.
  • the angle between the two slot walls is about 60° , while the angle between inner wall 27' and the support ring is about 30°, the transition zone being softly rounded off, which is clearly shown in Fig. 8.
  • Bottom 28 of slot 38 is situated at a level, which is about 1-5 mm, preferably about 2 mm, higher than free edge 39 of the support ring, while the front edge of inner wall 27' and the support ring is situated about 1-5 mm, preferably about 2 mm in front of the plane of the flange 20.
  • This means, that the symmetrical axis of the slot is directed obliquely towards and outwards , which has a practical significance, which can be seen at the transition from Fig. 12 to Fig. 13.
  • a tube 7 has been filled with a paste compound 11 and has a cap 12 and has, by means of not shown, already known machines, been introduced into the rear tube end 10, an air- filled space 29 having been confined.
  • a rotation-symmetrical tool 30, functioning as an introduction piston, which also can replace said machines, has in this shown phase been introduced into the rear open cap end 15, the tool, which preferably has a front bottom 31 with a front inner bevel 32 all around, connected thereto, abutting with the latter against the rear part of the outer side of outer wall 27.
  • the latter and bevel 32 has substantially the same conicity, i.e. preferably about 30° in relation to the longtitudinal axis or the angle between said outer side and the longitudinal axis can be somewhat larger, which is shown in Fig. 10.
  • bevel 32 does not in this first contact position 10
  • the entire cap then creeps on the front end of the tool, the outer side of outer wall 27 sliding on the inner bevel, the diameter of the cap simultaneously being reduced.
  • the cap material compressed in this way is removed, since bottom 24 becomes deeper and the bending radius is reduced, i.e. the center of the bottom is pushed forwards a small distance and its peripheral parts are pushed backwards a little.
  • the entrapped air can be discharged in the form av a short pressure wave, which also can be heard as a subdued bang.
  • the pressure increase of the initially entrapped and then discharged air also results in a very quick obliteration of the air-filled space 29, the turning over inwards of flange 20 facilitating the discharge of the air from the area in front of the bottom and into ring-shaped gap 36.
  • Bottom 31 of tool 30 reaches this position according to Fig. 3 against the free edge 39 of the support ring, an instrument being obtained, designed to affect the bottom in a phase following said initial phase and consequently result in a even better and more reliable air emptying.
  • the bottom recieves this pressure with a certain but small bending radius increase, i.e. the bottom is to a small extent made more level, flange 20 being tilted backwards a little more strongly and directed with its free outer edge 22 more accentuatedly and with a stronger pressure against the tube wall due to a levelling away of outer wall 27 in relation to the disc or a radial plane, a diameter increase of the cap within this area also taking place.
  • This flange tilting is caused by a lever-like actuation by the outer wall on the flange, since the support ring is pushed forward and the outer wall yields and levels away, while inner wall 27 ' is directed more parallel to and closer to the support ring. Since the tilting is slight and include only a few angular degrees, it can be repeated as many times as the operator wants, without any damage to the material and the shape of the cap.
  • the fact that the sharp flange edge is directed against the tube wall and that this is done with an increased pressure means, that a proper pushing forward of the contents in the cartridge without leaving behind any sticky residues is guaranteed in a far-reaching way.
  • the tool shown in Figs. 10 and 11 has, at its front end, a central, axially forwardly directed guide pin 40, which is designed to, with form fit, mesh with support ring 26 of the cap, a turning around of the cap being prevented.
