Definitions

  • Dough container tube comprising a reloading device locked by a screw cap.
  • the invention relates to a device for making rechargeable a tube used for packaging and dispensing of pastes such as toothpaste.
  • tubes intended for the packaging of pasta are well known; the tubes are essentially single-use products made up of a thin and flexible tube, either metallic or plastic; one end of the tube has a narrowing with a neck on which comes to adjust a plug which is generally screwed; the other end of the tube is first used to fill it with the dough to be packaged, then it is closed by crimping or welding.
  • the object of the present invention relates to a device allowing the reopening and reclosing of this tube with a wide opening, so that, when it is empty or insufficiently filled, it is possible to put dough back into it; indeed, if one wants to use a non-standard tube for single use (element of a compact toilet bag for example), there immediately arises a problem of restocking which is almost impossible to solve; hence the need to offer buyers toilet bags containing tubes that they can fill themselves and reload from the standard tubes they usually use; this concept of refillable tube helps to limit the consumption of packaging material for everyday products.
  • the concept of the rechargeable tube has already existed for several years; the tube is generally composed of a flexible plastic tube capable of resuming its initial shape, if possible without wrinkling, when the tube having been emptied, it is refilled; but the solutions used to date have drawbacks which it is advantageous to eliminate in order to simplify their implementation.
  • the known systems there is first a mechanical locking clamp of a tube whose bottom has been previously folded back on itself; this very simple system has the disadvantage of requiring a certain skill to put the clamp in place and it is an operation which is difficult to mechanize for the manufacturer of the tube who must put it in place first.
  • CH-A-230000 describes a refillable container tube according to the preamble of claim 1. More specifically, CH-A-230000 describes an oil burette refillable by a neck like filling a bottle, but which is not suitable for reloading with a paste because there immediately forms a plug of paste which sticks to the neck preventing further filling by resistance to compression of the trapped air.
  • an object of the present invention is to provide a device making it possible to place, at the filling end of the tube, a plug which is correctly lockable and easy to handle, while ensuring the reopening and reclosing of this tube with a wide opening, so that, when it is empty or insufficiently filled, dough can be put back into it.
  • this object is achieved by a paste container tube having the characteristics of the characterizing part of claim 1.
  • the female thread of one of the ends of the tube forms part of a shaped end piece substantially annular, which is inserted into the end of the tube and which is fixed to the filling end of the tube by friction welding.
  • Fig. 1 shows a dough container tube with the dispensing orifice facing downwards and the reloading orifice, in exploded view, to see the interior of the tube when the plug (4) is screwed in place.
  • Fig. 2 shows, in partially exploded view, the part of the tube intended for its recharging; this tube can cooperate with the stopper according to the invention of FIG. 3.
  • Fig. 3 shows an exploded view of the closure plug of the recharging orifice modified according to a variant of the invention to also serve as a product distribution orifice.
  • Fig.4 shows the part of the tube, intended for its recharging, with the annular end piece according to the invention, into which the plug (4) of Fig.1 is screwed, when it is fixed by friction welding before it is placed in the tube.
  • Fig.5 shows the part of the tube, intended for its recharging, with the annular end piece according to an embodiment not part of the invention in which the plug (4) is screwed Fig.1, when it is fixed by snap-fastening.
  • the device, object of the invention consists in equipping the filling end (1) Fig. 1 of the refillable tube (2) with a thread (3) inside the tube (2), leaving the largest passage filling (1) possible, onto which a plug (4) is screwed.
  • the tube (2) is obtained by injection, it is technically possible to obtain the thread (3) directly by injection, this embodiment not forming part of the invention;
  • the threaded neck (5), of small diameter, used to extract the dough from the tube has a male thread while the thread (3), from the filling orifice (1), into which a plug (4) is screwed ) is a female thread; under these conditions a screw cap (6) of the conventional type may be suitable for closing the tube on the side (7) of the product extraction and a plug (4) with male thread closes it on the side (1) of the filling.
  • Fig. 3 in two parts comprising, on the one hand, a male thread (11) which is screwed into the female thread (10) Fig. 2 of the tube (8), on the other hand, an extraction neck (12) Fig. 3 comprising a male thread on which is fixed the plug of the extraction orifice; this plug Fig.3 may further include a ribbed collar (13) to facilitate its screwing on the end (9) Fig.2 of the tube (8) and its unscrewing; the tube (8) is closed, at the other end, by a thermal weld as for the other plastic tubes; filling is done by unscrewing the neck assembly Fig.
  • this end piece (15), of annular shape comprises a cylindrical outer part (17) comprising a chamfer (18) at its lower end, so as to be fitted into the end (14) of the tube and comprise at the upper end a collar (19) whose width is for example the thickness (20) of the tube on the end (21) of which it comes to bear; then the end piece (15) is fixed by friction welding; the choice of materials is then made accordingly.
  • the end piece (15) made of a material compatible from the point of view of welding with the material of the tube, can be force-fitted and welded thermally through the wall (22) of the tube, at the height of the fitting, in an area of sufficient size to prevent the end piece (15) from escaping.
  • Friction welding can be obtained by putting the end piece (15) in rotation so as to obtain for example the welding of the flange (19) on the end (14) of the tube; this latter solution will nevertheless require a particular development allowing the flexible tube to be maintained during the welding phase so that it does not twist.
  • the snap fastening according to an embodiment not forming part of the invention can be obtained by making at least one projection (23) Fig.
  • the plug (4) Fig.1 which is the same as that used in the configurations described in Fig.4 and Fig.5 has a male threaded cylindrical part (35) Fig.1 which is screwed into the end piece (15) Fig. 4 or (25) Fig.5; this threaded part (35) Fig.1 is integral with a cylindrical part (36), the diameter of which is slightly greater than the outside diameter of the tube (2) in the case described in Fig.1 and of the flange (19) Fig. 4 or (29) Fig.5 of the nozzle, and whose cylindrical wall (37) is striated to allow a good grip for screwing and unscrewing; the lower part (38) of this striated cylindrical part abuts on the upper part of the collar (19) Fig.4.
  • the assembly of the plug (4) Fig.1 and the endpiece (15) Fig.4 comprises a braking or locking device preventing its untimely unscrewing;
  • the upper part of the collar (19) may for example include a device (38) for locking the plug (4) Fig. 1 when it is screwed on: the position of the plug (4) is known with good precision when is screwed onto the end piece (15) Fig.4 so we can for example provide on the collar (15) a protrusion (19) which will be housed at the end of screwing in a hollow in the lower part (38) Fig.
  • the two-part stopper described in Fig.2 can also be fixed on flexible cylindrical tubes comprising at one end a nozzle (19) Fig.4 or (25) Fig.5 and which can be closed at the other end by welding obtained , as described above, by crushing the tube, or crimping or any other closing means.
  • the plug assembly system (4) with the female screw thread (3) is taken as an example because other known systems can be used, in particular systems making it possible to obtain an assembly correctly locked in a quarter turn using for example threads interrupted, or applied to a conical surface, or a bayonet fixing system.
