Definitions

  • the present invention relates to an assembly as described in the preamble of the first claim.
  • Such an assembly is for example used for coupling a container, wherein a compound is stored, to a device, for example a gun, for applying said compound.
  • a gun for applying said compound.
  • Such guns are amongst others used for applying compositions, that can be composed of one or more components, for example a silicone paste, polyurethane foam or a two component glue.
  • the known assembly comprises a container and a first coupling piece, which is provided for being attached to the container.
  • the first coupling piece is mostly made of a plastics material.
  • the known assembly also comprises a second coupling piece, which is provided for being attached to the gun.
  • the second coupling piece is mostly made of metal, for example aluminium or bronze.
  • the first and the second coupling piece are rotatably connectable, by means of a screw thread.
  • the coupling is effected by inserting the first coupling piece into the second coupling piece, and tightening the screw thread until the stop position is reached. This is mostly performed manually.
  • the known assembly however has the disadvantage that it is rather difficult to unscrew the screw thread. It has namely been found that the screw thread contains compound present in the container. When it is the intention of re-using the container or the gun, and thus one or both of the coupling pieces, the coupling pieces and the screw thread included, have to be cleaned beforehand. Depending on the nature of the compound, this can be difficult, sometimes impossible.
  • the screw threads of the coupling pieces engage each other over a substantial part of their length, and thus over a plurality of windings.
  • the first coupling piece is rotated stepwise, a number of times with respect to the second coupling piece, until the stop position is attained.
  • the valve is opened by the second coupling piece. Because the valve is in contact with the second coupling piece almost from the beginning of the tightening of the coupling, the valve undergoes, from the beginning, every movement of the first and second coupling piece with respect to each other. Because the valve is already opened during the effectuation of the coupling, the valve leaks and the compound can leave the container before the coupling is achieved.
  • This problem of an undesired leaking of the valve during the effectuation of the coupling takes place particularly in case one or both coupling pieces are made of plastic. In practise, namely it has been revealed that a screw thread in plastic is rather coarse and shows a large clearance.
  • US-A-5.549.228 discloses a twist lock system for a dispensing container for a dispensing gun.
  • the twist lock system comprises a mounting adapter which is a detachable locking ring provided on the container and an attachment portion on the gun.
  • the ring includes a main ring with an opposed upper and lower surface, the lower surface being a bead engaging surface.
  • a pair of protrusions which are spaced apart by notches, and which comprise a down turned lug stop, extend inwardly from the ring.
  • the attachment portion includes a cylindrical side wall supporting a first pair of locating and a second pair of locking lugs, whereby both pairs are offset with respect to each other in the height direction of the cover.
  • the container is attached to the dispensing gun by positioning the first pair of locating lugs in the notches, and rotating the gun with respect to the dispenser until the leading edge of the locating lugs engages the lug stops. At that point, there is vertical alignment between the passages for allowing the product to leave the container.
  • the attachment portion is further pushed down towards the ring, thus lowering the locating lugs beneath the level of the lug stops, and thereafter twisted, so as to permit the locking lugs to pass beneath the lower surface of the protrusions of the ring, which prevents upward movement of the locking lugs.
  • the container valve is opened, and product present in the container flows from the container towards the dispenser.
  • the coupling can be effectuated in one continuous movement, whereby simultaneously the valve is opened in one continuous movement. Because the action time that is exerted to the valve is short, the risk to a leaking of the valve during the effectuation of the coupling is very small. Such a continuous one turn movement, consequently allows to minimise the leaking of the valve, during the effectuation of the coupling.
  • the first and second coupling pieces comprise co-operating means for bolting said coupling in the coupled state. This is namely of importance for preventing a loosening of the coupling in case the container contains a pressurised compound. In the known assembly, this is achieved in that the screw threads engage each other over a plurality of windings.
  • the means for bolting the coupling are preferably unboltable, so that the coupling can be re-used several times, i.e. opened and closed several times.
  • the means for bolting the coupling preferably comprise a snap lock.
  • a snap lock is bolted automatically when the coupling is effectuated.
  • the coupling element of the assembly according to the invention comprises a protrusion in the first and a guiding in the second piece, which guiding is to receive the protrusion.
  • the protrusion and guiding according to the invention preferably comprise at least one pin-and-groove connection.
  • the coupling can be effectuated in one short movement. Thereby a large tolerance can be provided, so as to facilitate the insertion of the pin in the groove, without thereby opening the valve and involving a risk to leaking of the valve.
  • the valve is namely only opened upon the movement of the pin in the groove, when the coupling piece that is provided for attachment to the device, acts upon the valve.
  • the pin-and-groove connection preferably comprises two pins (11) provided on diametrically opposed sides of the first coupling piece (1), and two grooves (21) provided on diametrically opposed sides of the second coupling piece (2) which grooves are provided to co-operate with said pins, so as to prevent that the coupling pieces, upon effectuation of the coupling, can be canted with respect to each other.
  • the coupling piece provided for attachment to the container preferably comprises means for attaching said coupling piece to the flange of the container head.
  • the container mostly comprises a substantially cylindrical container body, which is, at its lower portion, closed off with a bottom and at its upper portion with a container head.
  • the container head is attached to the container body by means of a substantially circular flange.
  • the container head comprises in its centre an opening with a substantially circular valve flange, for attaching the valve.
  • the coupling piece is attached to the valve flange.
  • the known container however has the disadvantage that it is very difficult, sometimes impossible, to unscrew the coupling. Thereby it may happen that upon unscrewing, when some force is exerted to the coupling piece, the coupling piece can be moved with respect to the container, in the peripheral direction of the valve flange. This may for example occur when the screw thread is fastened rather thoroughly, or when the screw thread contains some of the compound from the container. Such a movement of the coupling piece can also take place, when some force is exerted to the coupling piece, upon tightening of the screw thread.
  • the contact surface between the coupling piece and the container is significantly increased.
  • the presence of an increased contact surface involves that an increased frictional resistance has to be overcome in order to permit the coupling piece to be moved with respect to the container. This allows to obtain an improved attachment of the coupling piece to the container, and to prevent that the coupling piece is moveable with respect to the container.
  • the coupling piece preferably also comprises means for attaching the coupling piece to the valve flange of the container head.
  • the first and second coupling piece are preferably made of a plastic material, whether or not provided with fibrous reinforcing material.
  • the coupling pieces are preferably made of nylon-6 or polypropylene. Thereby, use can be made of the intrinsic resilience of the plastic material for the bolting and unbolting of the snap lock.
  • Preferred embodiments of the assembly according to the invention include an assembly of a container provided with the first coupling piece, and an assembly of a container provided with the second coupling piece.
  • Figure 1 shows a device for applying a two-component composition.
  • Figure 2 shows a cross section of a first preferred embodiment of the assembly of the present invention, with the coupling in respectively the uncoupled (figure 2a) and the coupled state (figure 2b).
  • FIGS 3a and 3b respectively, a top view and a side elevation view of the second coupling piece, are given.
  • Figure 3c and 3d show, respectively a top view and a side elevation view of the effectuated coupling are shown.
  • Figure 4a shows a second preferred embodiment of the coupling according to the invention
  • figure 4b shows a cross section of the second preferred embodiment in cross section.
  • the device shown in figure 1 comprises a gun 4 for applying a two-component composition.
  • a first container 3 contains a first component under pressure.
  • a second container 5 contains a second component under pressure.
  • the first container 3 is provided with a first coupling piece 1, which fits into the second coupling piece 2.
  • the second coupling piece 2 is provided for being connected to the gun 4.
  • the first coupling piece 1 and second coupling piece 2 are rotationally connectable.
  • the coupling pieces 1 and 2 are preferably made of a plastic material, for example nylon 6 or polypropylene.
  • the container 3 preferably has a substantially cylindrical body 10, and is provided with a container head 7.
  • the container head 7 is connected to the container body 10, by means of a flange 6.
  • the container head 7 contains a central hole with a valve flange 8, for receiving a valve 9.
  • the first coupling piece 1 is on the one hand, connected through a first recess 17 in its circumferential rim 16, to the flange 6 of the container head 7, and on the other hand, through a second recess 18 to the valve flange 8.
  • the circumferential rim 16 preferably comprises a protrusion 15, preferably a snap rim, which is provided to co-operate with the flange 6, for strengthening the attachment of the first coupling piece 1 to the container 3.
  • the valve 9 is fixed to the first coupling piece 1 by means of an at least partially compressible valve sealing ring 30.
  • the valve 9 can be opened in the direction of the internal volume of the container 3.
  • the component present in the container 3, can leave the container 3 through a passageway 32 in the valve 9, and further through the second coupling piece 2 towards the gun 4.
  • the external surface of the first coupling piece 1, preferably comprises a protrusion 11.
  • the second coupling piece 2 preferably comprises a guiding 21, which is provided for co-operating with the protrusion 11.
  • the protrusion 11 is provided to be movable within said guiding 21, between a start position 28 and a stop position 29.
  • the protrusion 11 and guiding 21 are preferably formed by a pin 11 and groove 21, respectively.
  • the embodiment shown in figure 2 comprises two diametrically opposed pins 11 and grooves 21. Because the pins 11 and grooves 21 are applied diametrically with respect to each other on the respective coupling pieces 1, 2, the process for producing such coupling pieces 1, 2 can be simplified.
  • a mould comprising two mirror symmetrical mould halves. For the opening and closing of the mould, the mould halves are movable from and to each other along a substantially straight line, whereby the use of rotating mould halves can be avoided.
  • the groove 21 has such a length that the pin 11 can be moved from the start position 28 to the stop position 29, within maximally one turn.
  • the length of the groove 21 can for example be equal to the circumference of the second coupling piece 2, or smaller.
  • Protrusion 11 and guiding 21 can be provided with complementary, co-operating surfaces, so as to obtain an improved grip.
  • Guiding 21 can be provided with a recess, extending in the direction of the lower rim 24 of the second coupling piece 2, so as to facilitate the insertion of the protrusion 11, without thereby opening the valve 9. Thereby a certain degree of play can be provided.
  • the protrusion 11 can have various shapes. It can for example be square, rectangular or any other shape.
  • the guiding 21 can be open towards the outer surface of the second coupling piece 2, or a groove-like recess in the internal surface of the wall of the second coupling piece 2, or comprise a set of rails applied to the internal surface of the second coupling piece 2, in which the protrusion 11 can be engaged.
  • the first and second coupling piece 1, 2 are preferably provided with a snap lock 12, 13, 14, 22, for bolting the coupling in an unboltable way.
  • a snap lock has the advantages of bolting automatically, from itself.
  • the circumferential rim 20 of the second coupling piece 2 comprises at least one recess 22.
  • the recess 22 is provided to co-operate with a lip 12, applied to the circumferential rim 16 of the first coupling piece 1.
  • the lip 12 is connected with the circumferential rim 16 through a connecting piece 13.
  • the lip 12 comprises, at the top, a jaw 14, which is provided to co-operate with the recess 22 in the circumferential rim 20 of the second coupling piece 2. If so desired, the jaw 14 and the recess 22 can be provided with co-operating, complementary profiles.

  • the internal rim 25 of the second coupling piece 2 is provided for engaging leak free against valve 9, after effectuation of the coupling.
  • a shaft 26 is provided wherein a part of the valve 9 fits, and through which the component coming from the container 3 can flow to the gun 4, through the one way valve 23.
  • the first coupling piece 1 Upon effectuation of the coupling, the first coupling piece 1 is inserted into the second coupling piece 2. Thereby, the protrusion 11 is inserted in a start position 28 in the corresponding guiding 21, as is shown in figure 3d. Thereafter, the first coupling piece 1 is rotated with respect to the second coupling piece 2, over maximally one turn, in one continuous movement. Thereby, the pin 11 is moved from its start position 28, towards a stop position 29, in the direction of the arrow in figure 3d. Simultaneously, the valve 9 is moved in the direction of the internal volume of the container 3, in one continuous movement (figure 2b), and the valve seal ring 30 is partially compressed.
  • valve 9 By the movement of the valve 9 in the direction of the internal volume of the container 3, the valve 9 is opened, and the compound can flow from the container 3, through the passageway 32 in the valve 9, towards the second coupling piece 2, in the direction of the arrows. Thereby, the one way valve 23 in the second coupling piece 2 is opened, whereafter the compound further flows in the direction of the gun 4, as is indicated by the arrows.
  • FIG. 4a Another preferred embodiment of the assembly of the present invention is shown in figure 4a and b.
  • the bolt 11, 12, 13, 22 is not applied to the circumferential rim of the coupling pieces 1, 2, but is provided to co-operate with the protrusion 11.
  • the first coupling piece 1 comprises a protrusion, preferably a pin 11 which co-operates with a guide, preferably a guiding 21 applied to the second coupling piece 2.
  • the pin 11 is moveable within said guiding 21, in the direction of the arrow in figure 4a, between a start position 28 for inserting the pin 11 in the guiding 21, and a stop position 29 which corresponds with a coupled state of the coupling.
  • an amount of play is provided in the start position 28, by means of a recess, which extends from the start position 28 in the guiding 21, towards the lower rim 34 of the second coupling piece 2.
  • the second coupling piece comprises on its outer surface, at the position of the stop position 29 of the guiding 21, a lip 35.
  • the lip 35 co-operates with the pin 11, for allowing the coupling to be bolted.
  • the lip 35 is, on its side which faces the pin 11, provided with a jaw 36, for keeping the pin 11 in its stop position 29.

  • the lip 35 is attached to the second coupling piece 2, by means of a connecting piece 37.
  • the lip 35 is preferably moveable from and towards the pin 11, and from and towards the second coupling piece 2.
  • Such a coupling can be effectuated by inserting the first coupling piece 1 into the second coupling piece 2, and inserting the pin 11 in its start position 28 in the guiding 21. Thereafter, the pin 11 is moved from its start position 28, in the direction of the stop position 29, by turning the first coupling piece 1 over maximum one turn with respect to the second coupling piece 2. When it has reached the neighbourhood of the stop position 29, the pin 11 comes into contact with the jaw 36 of the lip 35. Thereby, the lower part of lip 35 is moved by the pin 11, in a direction that points away from the second coupling piece 2, as is indicated by the dotted line in figure 4a. When the pin 11 reaches its stop position 29, the lip 35 is moved back towards the second coupling piece 2. The coupling is than bolted, because the complementary surfaces of the pin 11 and the jaw 36, maintain the pin 11 in its stop position 29.
  • the jaw 36 is moved in a direction that points away from the second coupling piece 2, by moving the upper part of the lip 35 in the direction of the second coupling piece 2. Because the pin 11 is no longer maintained in its stop position 29, by the jaw 35, the pin 11 can be moved from its stop position 29 towards its start position 28, and the coupling pieces 1, 2 can be moved in a direction against the direction of the arrow, and be uncoupled.
