Definitions

  • the present invention concerns a pocket sprayer with a receptacle for the substance to be sprayed which is closed by a head piece having an atomising nozzle arranged therein.
  • Fig. 3 is an axial section through a modification of a part of this pocket sprayer of Fig. 1;
  • central extension 5 which is provided with external screwthreads 6.
  • Screwed on external screw-threads 6 of the extension 5 is a ring 7 which has, on its side that is to lie against the head piece 2, a projecting, widened or en larged part 8 which, when the ring 7 has been completely screwed on the external screwthreads 6 of the extension 5, completely covers the shoulder 4.
  • a packing or sealing sleeve 9 In the widened part 8 of the ring 7 there is inserted a packing or sealing sleeve 9, the bottom thereof forming an outwardly extending edge which rests on the surface of the part 3 which is to lie against the head piece 2 and the top thereof forming an inwardly extending edge which rests on the bottom surface of the ring 7.
  • This packing sleeve 9 is kept in the widened part 8 of the ring 7 by an annular head 10 which is provided on the outside of itscentral, cylindrical part, and which engages in a groove in the inside surface of the widened part 8 of the ring 7.
  • the extension 5 has an axial bore 11 which passes through the head piece 2 and the upper, wider part 11 of which is provided with an external screw thread 12, into which a central screwthreaded extension 14, which is mounted on the underside of a plate 13 which projects beyond the extension 5, is screwed.
  • a packing ring 15 is inserted between the plate 13 and the top edge of the extension 5.
  • the plate 13, has, on its upper side, a central extension 16 which has, on its topend, a spherical head 17 which is grooved underneath.
  • the extension 16, the plate 13' and the screw-threaded extension 14 have an axial bore 18 passing through them.
  • This plate 21 is kept in the cap 20 by means of an edge head 22 which engages in a groove provided in the inner surface of thecap 20 and it has, at the centre, a bearing 23 for the. head 17 of the extension 16 which is provided with an inwardly extending edge head 24 that can engage in the groove beneath the head 17 of the extension 16.
  • a conical compression spring 25 which tends to push the plate 21 and, consequently, the cap 20 upwards out of the sleeve 19.
  • the sleeve 19 has,.at its top end, an inwardly projectiug edge bead 19 and the cap 20 has, at its bottom end, an outwardly projecting edge head 20', so that the cap 20 can be pressed outwards in the sleeve only until itsedge head 20' lies on the edgebead 19 of the sleeve 19.
  • a central air aperture 26 In the end face of the cap 20 there is provided a central air aperture 26 and the plate 21 has air apertures 27.
  • the cap '20 is pressed completely into the sleeve 19 and is retained by the'edge bead 24 of the bearing 23, which bead is engaging in the groove beneath the head 17, in opposition to the action of the compression spring 25 At the same time, the opening of the bore 18 is closed quite tightly by the bearing 23 of the plate 21,which bearing extends over the head 17.
  • the container 1 is consequently hermetically closed and its contents can neither'fiow out or evaporate.
  • This sheet-metal cup 38 has a central aperture 41 and a flange 42 which surrounds the latter and which is divided into resilient flaps by recesses 43 which extend radially from the central aperture 41. These resilient flaps are so made that they engage in the'underneath groove of the head 17 of the extension 16 which is pressed into the central aperture 41 of the sheet-metal cup 38 and can retain the head 17 resiliently. Above the sheet-metal cup 38 a packing disc 44 is inserted in the cap 20 which'is provided with air apertures 45 and which, when the head 17 of the extension 16 passes through the central opening 41, tightly closes its axial bore 18.
  • the pocket sprayer can also be constructed for spraying pulverulent substances, for example disinfectants.
  • the atomising nozzle 31 is advantageously not provided with a rising tube and, for that purpose, there is connected to the sleeve 36 a tube 47 which extends down into the bottom part of the container 1. By means of this tube a part of the compressed air is led into the bottom part of the container 1 where it whirls upwards the substance to be sprayed. V
  • pocket sprayer represented in Figs. 6 and 7 agrees, in general construction, with the pocket sprayer represented in Figs. 1 and 2 and it differs therefrom only bythe' construction of the retaining device for the cap 20 and 'by the means for sealing the continuous axial bore passingthrough the part that is screwed into the extension 5 of the head piece 2.
  • the same reference numerals are used for the parts of the pocket sprayer according to Figs. 6 and 7 which agree exactly with those of the pocket sprayer shown in Fig. 2 and, with regard to the description of these parts, reference is made to the foregoing description.
  • the plate 50 On its upper side, the plate 50 has a central extension 50".
  • the plate 50,- the screw-threaded extension 50 and the extension 50 have an axial bore 51 which passes through them and in which there lies, with ample clearance, a valve spindle 52 on the bottom end of which a valve cone 52' is mounted, for which a conical widening of the opening of the bore 51 forms the 'valve seating on the end of the screw-threaded extension 50'.
  • a ball 53 which is held by a'head 52" of the valve spindle 52;
  • the extension '50" has, on 7 its top end, a slot 54 which extends transversely over its whole diameter.
  • a ring 55 which preferably consists of elastic material and in which the upper part, consisting of a spring part 56 and a spring 56", of a push-button like retaining device, is held, the bottom part of which 'is formed by the ball 53.
  • the ring 55 is held in the cap 20 by a sleeve 57 which is rigidly in U serted' in the cap and between the bottom outwardly flanged edge 57' of which and the bottom edge of the cap 20 an elastic packing ring 58, which rests on the inner surface of the sleeve 19, is inserted.
  • the ring 7, 8 which is rigidly mounted in the sleeve I9, is screwed upwards, by rotating the sleeve 19, on the external screw-threads 60f the extension 5' until the ring 7 rests on the plate 50 or on the packing ring 15, the ball 53 is pulled out of the spring part 56.
  • the effect of this is that the valve spindle 52 is freed and the valve cone 52' opens the opening of the bore 51.
  • a pocket sprayer with a receptacle for the substance to be sprayed which is closed by a head piece having an atomising nozzle arranged therein; characterised by the feature that there is provided, on the top of the head piece, on a shoulder in the peripheral surface of which the aperture of the sprayer is provided, a central extension which is provided with an external screw-thread and on which there can be screwed a ring which has, on its side that is to lie against the head piece, a widened part in which a packing sleeve is inserted and which, when the ring has been completely screwed on the outer screw-thread of the extension of the head piece, covers the shoulder of the head piece together with the aperture of the sprayer in a sealing manner and, when the ring is located in an outer limiting position, which is determined by a stop, frees the aperture of the sprayer, and in which there is fixed on the said ring a sleeve, in the part of which that projects over the ring, a cap, which
