Definitions

  • the invention relates to a closure, pouring and dosing device for plastic bottles, with a closure cap, which consists of an essentially cylindrical dosing cup with an externally attached collar, which for closing the bottle has a cylindrical part arranged concentrically to the dosing cup with an internal thread, the When the bottle is closed, the rim of the dosing cup protrudes into the inside of the bottle neck.
  • Such caps are used, for example, for the metered addition of liquid washing or rinsing agents in washing machines and the like.
  • the inside of the unscrewed cap is used as a dosing cup.
  • the closure caps have an internal thread on their edge, which can be screwed onto a corresponding external thread of the bottle neck.
  • the caps have been designed in such a way that the thread of the closure cap is arranged on a collar attached to the outside of a metering cup so that the edge of the metering cup protrudes into the bottle neck when the cap is replaced on the bottle and liquid therein runs down the wall of the metering cup and drips into the bottle. In this way, the thread and the bottle exterior remain clean and do not come into contact with the liquid.
  • the amounts of liquid to be dosed or filled can be quite substantial, so that the dosing cup must be made correspondingly large by a factor of two, three or more Avoid filling the dosing cup in a single dosing process.
  • the dosing cup or the closure cap cannot be made as long and tall as desired, since it is generally placed upside down on a table or the like for filling so that the dosing cup can be filled.
  • the diameter of the closure cap or the dosing cup and thus also the bottle neck must be correspondingly large.
  • such a device in which the bottle neck is provided with an insert, the insert artificially narrowing the bottle neck and being formed in its center as a pouring spout in the form of a narrow, high channel which projects upward from the bottle neck.
  • the present invention has for its object to provide a closure, dosing and pouring device with the features mentioned, when used as intended, the closure threads are not contaminated, which nevertheless allows easy and convenient dosing and which also in machine handling is easier.
  • an intermediate base is arranged in the transition region between the bottle container and the bottle neck, that the intermediate base is attached to the bottle neck and that the intermediate base or the parts connecting the intermediate base to the bottle neck have several openings for the discharge of liquid from the bottle on the one hand and are arranged for the admission of air into the bottle on the other hand.
  • the wide bottle neck is still used as a pouring opening, but this pouring opening is considerably limited in its cross section by an intermediate bottom, so that large quantities of liquid cannot suddenly escape from the bottle neck.
  • the liquid to be filled into the dosing cup can therefore be dosed correctly without too much care. Since the dosing cup protrudes into the bottle neck when the bottle is closed, the intermediate bottom must be arranged correspondingly deep in the bottle neck or in the transition area between bottle and bottle neck.
  • the intermediate floor extends substantially into the bottle container Lich cylindrical or conical wall parts is arranged and that the openings in the wall parts are arranged directly on the edge of the intermediate floor.
  • the intermediate floor with the wall parts is arranged on an insert which is separate from the bottle and can be placed on the bottle neck.
  • the insert essentially consists of two concentric cylindrical parts which are connected to one another by an annular part, the outer cylinder being securely attachable to the bottle and the inner cylinder having the intermediate base at its end projecting into the bottle neck.
  • the insert After filling the bottle, the insert can be more or less firmly connected to the bottle, since only the cap has to be released from the container.
  • the invention provides that the outer cylinder has an internal thread which can be screwed onto a corresponding external thread of the bottle neck and that a group of cams is arranged on each thread, which by screwing the threads can be brought into engagement with one another.
  • cams in the threaded area means only a minimal change, so that the changeover to the closure cap according to the invention can be carried out without great expense.
  • the cams do not have to be arranged directly on the thread, but can be arranged on the edges of the insert or the outer cylinder of the insert and the bottle neck or the bottle container, which are in engagement with one another.
  • At least one of the groups of cams has a flank that rises flat in the direction of rotation against the thread of the other part, while the other flanks drop steeply in the radial direction.
  • the invention further provides that a screw thread is arranged on the outside of the insert.
  • a closure cap of the type described above can be screwed onto this.
  • the screw thread is arranged on a cylindrical extension which extends concentrically to the bottle neck and outside the bottle in extension of the wall parts or from the annular connecting part the cap can be screwed onto this approach.
  • the insert which is screwed onto the actual bottle neck, thus imitates the thread of the bottle neck in extension, the respective thread diameter of the bottle neck and the attachment on the insert being able to be the same or different.
  • An advantageous embodiment of the invention is characterized in that the bottom of the insert is substantially conical with a conical tip pointing outwards with respect to the bottle. In this way it is achieved that the liquid which runs back from the dosing cup into the insert is drained out through the conical surface of the intermediate base in the direction of the openings and can flow through them.
  • the openings are in each case the same size and each between approximately 4 and approximately 40 mm 2, the total cross section of the opening not exceeding 50% of the opening cross section of the bottle neck.
  • the size of the individual openings naturally also depends on the viscosity of the different ones in the bottles filled liquids together, but can vary for a given viscosity in a wide range, without any disadvantages for the pouring.
  • the larger the individual openings or the larger their total number or their total cross section the more liquid will emerge from the bottle opening per unit of time.
  • the advantageous properties of the invention are retained as long as the total cross section of all openings does not exceed 50% of the opening cross section of the bottle neck.
  • a particular advantage of the invention lies in the simple handling.
  • the main advantage is that the orientation of the insert with respect to the bottle or a bottle handle is not important. The use remains effective in every orientation.
  • the closure, pouring and dosing device consists essentially of the closure cap 1 and the insert 11 screwed onto the bottle neck 7.
  • the closure cap 1 in turn consists of the dosing cup 2 and the collar 3 attached to it with a cylindrical part 4 with an internal thread, which is arranged essentially concentrically to the dosing cup.
  • the insert 11 exists likewise essentially consisting of two cylindrical parts, namely the outer cylinder 12 and the inner wall parts 10, in the axial extension of which the likewise cylindrical extension 14 is also formed with an external thread.
  • the cylinder consisting of the wall parts 10 and the attachment 14 is connected via the annular connecting part 15 to the outer cylinder 12, which has an internal thread 5 which can be screwed onto the thread of the bottle neck 7.
  • the outer cylinder 12 does not have to be cylindrical in the strict sense, but can, apart from the internal thread and as shown in Figures 1 and 2, be adapted on the outside to the design of the bottle and be more or less conical or have a different cross-sectional shape .
  • cams 16 are arranged in the lower region of the bottle neck thread and of the outer cylinder, which interlock and secure the insert 11 screwed onto the bottle neck against loosening.
  • the cams 16 are designed in such a way that when the insert 11 is screwed onto the bottle neck 7, flat cam flanks slide onto one another and thus enable screwing, while when unscrewing in the opposite direction, very steep cam surfaces come into contact with one another and thus insert 11 on the bottle neck 7 to back up.
  • the wall parts 10 are slightly tapered inwards at their lower edge 6 and connected to the intermediate floor 8 at their lower end.
  • the intermediate base 8 is conical, the tip of the cone in FIG. 1 coinciding with the central vertical line which separates the part of the device shown in section from the rest.
  • edge web 17 of the intermediate base 8, the inner edge of the bottle neck 7 and the openings 9 form a relatively narrow passage for those from the bottle liquid to be poured.
  • the cap is flat on its top, and can be placed upside down on a table or the like so that the dosing cup 2 can be filled from the bottle.
  • the openings 9 are arranged evenly in the circumferential direction at the lower edge 6 of the wall part 10, so that when pouring out at least one or more openings 9 for the inlet of air into the bottle are at the top if the bottle is not completely tilted into a vertical overhead position.
  • the cap 1 is only screwed onto the thread of the projection 14 and released from it without the insert 11 also being unscrewed since it is secured by the cams 16. For easier loosening and tightening of the closure cap 1, this is provided on the outside with gripping grooves or webs.
  • the liquid still in the dosing cup 2 flows, after replacing the cap 1 on the insert 11 and thus on the bottle neck 7, down on the inner walls of the dosing cup 2 and on the intermediate base 8, its conical surface ensuring that the liquid after flows out through the openings 9 into the bottle container 18.
  • the entire facility is designed for easy handling, easy manufacture and economical use of materials. Otherwise, the wall parts 10 could also be made longer and the intermediate floor 8 extend deeper into the bottle container. However, the dosing cup 2 and the wall parts 10 could also be shortened further in order to save even more material. However, such savings are, above all, limited by the fact that the dosing cup 2 should have a predetermined volume for the absorption of liquid.
  • the embodiment shown is largely optimized with regard to stability, volume and economical use of materials.
