Definitions

  • the invention relates to a spray closure for the neck opening of a container, in particular for hair cosmetics, according to the preamble of claim 1.
  • a spray closure of this type is known from US-A-3 488 002.
  • a spray bottle with compressible wall is described, on the neck of which a cap is screwed.
  • a plug-like spray unit is inserted into the neck with a snap fit and comprises a cylindrical body.
  • In the overhead position of the container there is a chamber below the center of the cylindrical body, one end of which opens into a spray opening and the other end of which is connected to an opening of an air tube.
  • the air tube extends close to the closed, curved top of the container above a liquid level.
  • the lower end of the air tube is firmly inserted into a circular recess along the vertical axis of the cylindrical body.
  • the cylindrical body there is a channel which extends at right angles from an inlet in the bottom wall to an outlet of said chamber between the spray opening and the air pipe opening, so that the liquid contained in the container flows into the chamber and mixes there with air from the air pipe can be.
  • the diameter of the air tube opening is smaller than the diameter of the outlet of the liquid channel, the diameter of the spray opening being between the two diameters mentioned.
  • the cap is provided with a projection which closes the spray opening when the cap is attached to the container.
  • Application systems consist of plastic bottles in connection with inserted plastic plugs which have a dispensing opening. Such systems are u. a. applied in the cosmetics area, especially in the hair care area. These systems essentially serve the purpose of applying a certain liquid, with an exact dosage and precise wetting of the surface to be treated leaving something to be desired, because the application rates vary widely. So it often happens that through the uncontrolled discharge of the liquid targeted treatment of z. B. wrapped curls with a certain amount of a hair cosmetic curl for curl is not possible and thus an uneven wetting of the entire hair takes place.
  • the invention is therefore based on the object of providing a spray closure for a so-called squeeze bottle, that is to say a container with an at least partially elastic wall, generally made of plastic, with which only in the overhead position of the container and only by compressing the container wall sprayed the container liquid as well as a more precise dosage of the dispensed amount in Form of a spray with a simple structure in the sense of an economical mass production can be made possible.
  • a container 10 is shown, the neck 20 of which is provided with a neck opening 12, into which a spray closure 14 is inserted, which can be actuated by compressing the at least partially elastic wall of the container 10, which is preferably made of plastic.
  • the container 10 can only be actuated in its overhead position.
  • the spray closure 14 consists of a plug-like insert 16 which can be inserted into the neck opening 12 and which rests with an annular shoulder 18 on the annular end face 19 of the container neck 20 and adheres firmly to the inner wall of the container neck 20 with frictional engagement.
  • the spray closure 14 also consists of a cap 22 which is provided with an outlet opening 24 and a corrugation 26 on the outer circumference. The corrugation facilitates turning the cap 22.
  • the cap 22 and the insert 16 are connected to one another by a connection 28 and are produced as a one-piece plastic molding.
  • the cap 22 as will be explained in more detail below, is rotatably arranged on the insert 16 between a closed and an open spray position.
  • the insert 16 has an air tube 30 with an inner coaxial air channel 32, the air tube 30 in the part 34 of the interior 36 of the container 10 containing air 34 protrudes.
  • the air tube 30 is formed in one piece with the insert 16 and extends laterally from the vertical central longitudinal axis y of the container 10.
  • the insert 16 is also provided with at least one liquid bore 38, which has an inlet opening 46 in an end face 52 facing the interior 36 of the container 10 and a mouth opening 54 in the end face 48 facing the cap 22, which is at the level of a neck extension 50 on the container 10 lies.
  • the liquid bore 38 connects the interior 36 of the container 10 with a liquid channel 40.
  • This liquid channel 40 opens into an outlet bore 42 of the air tube 30.
  • the diameter of the outlet bore 42 of the air tube 30 is smaller than the inside diameter of the air channel 32 in the air tube 30.
  • the diameter of the outlet bore 42 of the air tube 30 preferably corresponds to approximately one sixth of the clear diameter of the air channel 32 in the air tube 30. However, ratios of these diameters deviating from this can also be expedient.
  • the outlet bore 42 of the air channel 32 is sealed by the cap 22 in its closed rotational position and connected in the open rotational position to the outlet opening 24 in the cap 22, so that the liquid can flow out and be atomized.
  • the outlet opening 24 of the cap 22 is arranged coaxially in front of the outlet bore 42 of the air duct 32 in the spray position and has a diameter that corresponds at least to that of the outlet bore 42.
  • the diameter of the outlet bore 42 of the air duct 32 and the diameter of the liquid bore 38 in the insert 16 are of approximately the same size. However, the dimensioning of these diameters must always be adapted to the special operating requirements.
  • the free end of the air tube 30 is arranged approximately at the middle level of the interior 36 of the container 10, so that it is in the normal rest position of the container according to FIG. 1 and in the operating position of the container according to FIG. 2 above the level one in Contained treatment liquid 44 is the z. B.
  • the liquid channel 40 is embodied in the upper end face 48 of the insert 16 facing the cap 22 as an open groove 52 which, together with the liquid bore 38, is constantly sealed off from the outside by the cap 22.
  • the liquid bore 38 and the outlet bore 42 of the air tube 30 advantageously each form a right angle with the liquid channel 40 connecting them.
  • the liquid channel 40 extends diametrically in the end face 48 of the insert 16, an opening 54 of the liquid bore 38 and the outlet bore 42 being arranged symmetrically with respect to the main axis y of the container 10, i. H. 1 and 2 are equally spaced to the left and right of the main axis y.
  • a different assignment of the liquid bore and outlet bore mentioned to the main axis can also be selected.
  • the cap 22 is provided on its underside 55 facing the insert 16 with an annular collar-shaped snap-in element 60 with which the cap 22 is axially inserted into a correspondingly shaped, annular groove-like latching device 62 in the upper end face 48 of the insert 16 Preload engages.
  • the snap-in element 60 is provided with an annular locking shoulder 64 which resiliently fits into an annular undercut 66 in a side wall 68 of the locking device 62 engages and secures the axially sealingly biased rotary seat of the cap 22 on the insert 16.
  • the cap 22 is rotatably supported to a limited extent in the insert 16 between its closed position and its spray position.
  • the snap-in element 60 is provided on the underside of the cap 22 with a rotation-limiting element 70, which projects downward beyond the snap-in element 60 (FIG. 4) and engages axially and rotatably in a rotation-limiting groove 72 of the latching device 62 of the insert 16.
  • This rotation limiting groove 72 represents a deeper circular arc section of the latching device 62. It extends, as shown in FIG. 3, over a circular arc of at least 90 °, the end faces at the two ends of the circular arc limiting rotation groove 72 stops 74 and 76 for the rotation limiting element 70 form in the closed position or open spray position.
  • the insert 16 and the cap 22 are connected to one another by an elastic connection 78 and are designed as a one-piece plastic molding.
  • the connection 78 can be designed such that it is destroyed when the cap 22 is mounted on the insert 16.
  • the connection 78 can also serve as a guarantee that is destroyed when the cap 22 is rotated for the first time. This is only a question of the corresponding design of a predetermined breaking point in the area of the connection 78, which is known per se and is therefore not shown.
  • the outlet opening 24 in the cap 22 is arranged eccentrically with respect to the central longitudinal axis or axis of rotation of the cap 22. Therefore, when the cap 22 is placed on the insert 16 from the position shown in FIG. 3, the rotation limiting element 70 lies in the rotation limiting groove 72 in front of the stop 74 which prevents the rotary movement of the cap 22 in the direction limited to the closed position. If the cap 22 is now rotated by approximately 90 ° against the stop 76, the outlet opening 24 of the cap 22 is located coaxially above the outlet bore 42 of the air channel 32, so that when the elastic wall of the container 10 is compressed in the position shown in FIG.
  • Air 34 emerges from the interior 36 at high speed through the outlet bore 42, thereby drawing liquid 44 through the liquid bore 38 and the liquid channel 40 into the outlet bore 42, tearing it in droplet form and out of the outlet opening 24 of the cap 22 as a fine spray 84 in a precisely metered manner Amount sprayed. This fine dosing is significantly favored by the suction effect described.
  • FIG. 3 shows a further liquid bore 80, which is likewise connected to the outlet bore 42 via a liquid channel 82 radial to the outlet bore 42 of the air duct 32.
  • the number of liquid bores 38 and 80 as well as the associated liquid channels 40, 82 and their dimensioning depend very much on the medium to be sprayed and on the hydrostatic pressure of the liquid column above the liquid bores 38, 80.
  • the dimensioning is in any case so choose that when the container is used overhead, no product can flow out independently due to the hydrostatic pressure of the liquid column.
  • the outlet opening 24 is not arranged above the outlet bore 42 of the air duct 32, so that a closed packing unit is produced without an additional overcap.
  • the spray closure 14 only allows overhead use.
  • the air 34 is pressed through the air channel 32 and, owing to the relatively high air speed in the outlet bore 42, a vacuum is generated between the air channel 32 and the liquid channels 40 or 820.
  • This vacuum draws the liquid 44 in and mixes it with the air 34.
  • This mixture then emerges as the relatively fine spray 84.
  • the fact that relatively large amounts of air get through the outlet bore 42 also prevents the small outlet bore 42 from becoming blocked in the case of highly viscous and sticky liquids.
