Definitions

  • the invention relates to a rotary closure for closing the axial opening of a hollow cylindrical body.
  • twist locks are e.g. used to close containers that can hold a liquid or powdery filling material and release it when the screw cap is open.
  • the body to be closed with the twist lock can form the container itself or can be designed as a body belonging to the twist lock which is screwed onto the neck of a container by means of an internal or external thread.
  • a plug forming the body is inserted into the neck of a container with the aid of a one-piece suspension.
  • the plug consists of a coaxial central post which carries at its axial end a valve body which interacts with an axial through-bore of the rotary cover. With the help of the suspension, the coaxial center post and thus also the valve body can be pressed axially inwards when the rotating lid is closed, whereby the through hole in the rotating lid is released in order to be able to fill the container from the outside.
  • the rotating lid is partially unscrewed, as a result of which the through hole of the rotating lid moves away from the valve body in the axial direction in order to expose a free outlet cross section.
  • the suspension holding the plug or the center post comprises radial ribs which are fixed to the inner surface of the body and are connected to the coaxial center post.
  • the object of the invention is to design such a rotary closure in such a way that it can be produced in a simple manner, is easy to handle and enables the contents contained in the body to be dispensed without hindrance.
  • the rotary lock according to the invention is characterized in that it carries out an axial displacement to the body with the aid of the cam thread when it is rotated by 180 ° relative to the latter. During this axial displacement, however, the rotating lid is not released from the body in the open position of the container, but rather an opening provided axially or radially in the rotating lid is released in order to be able to dispense filling material present in the body to the outside.
  • the mutually facing axial sides of both the rotary cover and the body run in a plane inclined by a certain angle with respect to the axis of the body. In the closed position of the twist lock, these bevelled sides are aligned with one another, while in the open position of the twist lock they diverge.
  • the rotating lid and the body of the twist lock are not separated from one another in normal operation even in the open position, they are preferably manufactured as separate individual parts from plastic, as a result of which they can have different colors in order to optimize the aesthetic impression of the twist lock.
  • the rotary lock shown in perspective in FIG. 1 consists of a rotary cover 1 and a body 2. Although the cover 1 is not detached from the body 2 during normal use of the rotary lock, here the cover 1 is removed from the body 2 for better illustration of the structure of the rotary lock shown separately.
  • rotary cover 1 and body 2 comprise cam threads 3 which correspond to one another and bring about an axial displacement of the rotary cover 1 relative to the body 2 when the rotary cover 1 rotates about the axis of the body 2 executes over an angle of rotation of approx. 180 °.
  • the mutually facing axial sides 4 and 5 of the rotary cover 1 and the body 2 are inclined by a certain angle ⁇ with respect to the axis.
  • the size of the angle ⁇ depends on the pitch of the cam thread 3.
  • the body 2 is provided with a central post 12 which is fixed to the inner lateral surface of the body 2 via ribs 13.
  • the rotating lid 1 has a central opening 14 which penetrates its axial end face facing away from the body. This opening 14 is provided with a locking seat 15 which cooperates with a corresponding sealing surface of the central post 12 in order to tightly close the opening 14 when the rotary lock is closed.
  • the body 2 is screwed onto the neck of a container, not shown, with an internal thread 11 provided on its inner lateral surface.
  • a container can contain a liquid or powdery filling material in a known manner, which can be dispensed via the opening 14 provided in the rotary closure.
  • FIGS. 2b and 2d the beveled and mutually facing axial sides 4 and 5 of the rotating cover 1 and the body 2 can be seen. Fig.
  • the rotary cover 1 can also be provided with such an extension directed towards the body 2, which is then likewise formed by a jacket surface engaging in the body 2.
  • the rotary cover 1 can have four ribs, which in this exemplary embodiment serve to center the rotary cover 1 with respect to the body 2, and in the exemplary embodiments explained later in connection with FIGS. 3 and 4 can take on an additional function.
  • the further exemplary embodiment of the twist lock shown in FIGS. 3a to 3f differs from the previously explained exemplary embodiment in that the ribs 13 inside the body 2 via hinges 16 are fastened to both the center post 12 and to the inner lateral surface of the body 2.
  • the ribs 13 articulated on the center post 12 and on the body 2 via the hinges 16 are elastic and act as leaf springs.
  • Four ribs 17 formed in the rotating cover 1 interact with the central post 12, which has a square cross-sectional profile here, and are arranged in a manner similar to that shown in FIG. 2c and indicated in FIGS. 3d and 3f.
  • twist lock also corresponds to the construction already explained in connection with the first exemplary embodiment in this exemplary embodiment.
  • FIG. 3 shows a modification of the embodiment shown in FIG. 3.
  • This modified exemplary embodiment differs from the exemplary embodiment illustrated in FIG. 3 in that three elastic ribs 13 are provided in the body 2, which are each fastened in the same way to the central post 12 and the inner lateral surface of the body 2 via hinges 16.
  • the center post 12 has a cross-sectional profile in the form of an isosceles triangle.
  • the rotary cover 1 is provided with three ribs 17, each of which is non-positively engaged with one side of the central post 12.
  • FIG. 5a to 5e show a further embodiment of the twist lock, in which the body 2 itself is designed as a container.
  • the rotating lid 1 has an outer surface 6 engaging in the interior of the container 2, in which an opening 9 penetrating it in the radial direction is provided.
  • the opening 9 is from the lateral surface of the Container 2 completely released so that the contents in the container 2 can be dispensed through the opening 9.
  • the radial opening 9 in the rotary cover 1 provided in the previously described exemplary embodiment is provided with a dispensing nozzle 10 which is articulated via a hinge joint 18 on the lateral surface 6 of the rotary cover 1.
  • the dispensing spout 10 is pivoted outwards by hand or by the action of gravity, so that the filling material located in the container 2 can be deliberately discharged to the outside.
  • the rotating lid 1 is used to close a tube or a hollow cylindrical rod, such as those used for towel racks or the like.
  • a locking projection 7 is arranged resiliently with the aid of grooves 19.
  • This locking projection 7 can in a in the inner surface of the Kör Pers 2 provided locking recess 8, as shown in particular in Fig. 7b.
  • Locking projection 7 and locking recess 8 can not only be arranged in the manner shown here, in which the rotating lid 1 is locked in the "open position" of the body 2. As already explained above, in this “open position” the mutually facing axial sides 4 and 5 of the rotating cover 1 and the body 2 diverge.
  • locking projection 7 and locking recess 8 can also be arranged in a manner not shown here in such a way that they lock together when the rotary cover 1 is in its "closed position", in which the mutually facing axial sides 4 and 5 are aligned.
  • the rotary cover 1 and the body 2 are each produced as separate parts. These parts are preferably injection molded from plastic or produced in some other way. Rotating lid 1 and body 2 can therefore have different colors in order to further optimize the aesthetic impression of the twist lock.
  • the rotary cover 1 can have different shapes and patterns on its outside in order to adapt the aesthetic impression to the particular requirements and applications desired.
  • the rotary cover 1 can also be exchanged for another rotary cover 1 with an otherwise identical rotary closure.
  • cam thread 3 can be provided with notches in order to provide latching positions for the rotary cover 1 at the two end points of the 180 ° rotation.
  • the body 2, the spring-like ribs 13 and the middle post 12 are preferably each made in one piece from plastic by injection molding.
  • the spring arrangement formed by the ribs 13 defines the maximum angle of rotation of the rotating lid 1 with respect to the container 2, the maximum angle of rotation again being 180 °.
