Definitions

  • the invention relates to a rotary closure cap made of plastic for a container having a container mouthpiece.
  • plastic closures for beverage containers which allow drinking from the container without the plastic closure is previously completely removed from the container.
  • plastic closures that allow drinking "through the plastic closure”.
  • Such a plastic closure for example, the document discloses US 5,975,369 , This plastic closure consists of several parts, and forms between the mouthpiece and the interior of the container a re-sealable drinking channel.
  • Such plastic closures enjoy increasing popularity because they are easy to use, and also allow easy and comfortable drinking.
  • plastic closures have the disadvantage that the production of the cap is complicated and therefore relatively expensive.
  • This plastic closure is also suitable for pressurized drinks only limited.
  • the document US 3,261,513 discloses a plastic closure provided for dispensing creamy substances to allow hygienic removal of the creamy substance from a container.
  • This plastic closure is not suitable as a closure of a drinking container to allow drinking "through the plastic closure" through. Even with heavy sucking on the plastic closure, the liquid contained in the drinking container could hardly be removed.
  • this plastic closure is not suitable for a pressurized drink. This plastic closure is therefore not suitable for a pleasant drink.
  • the dependent claims 2 to 15 relate to further, advantageously designed rotary closure caps.
  • a rotary closure cap made of plastic for a container having a container mouthpiece with an outer circumferential guide, consisting of a in the Basic shape cylindrical shell and a substantially circular disk-shaped head plate, on the inside of an annular circumferential, one-piece sealing lip is formed, wherein the rotary closure cap has at least one outlet opening, which is arranged outside of an enclosed by the circumferential sealing lip inner region and extending arcuately in the circumferential direction of the top plate, and wherein a cap mouthpiece on the outside of Rotary closure cap is formed, and wherein the outlet opening opens into the cap mouthpiece, and wherein the cylindrical jacket has an inner circumferential guide, which is configured so cooperating with the outer circumferential guide, that the rotary closure cap is rotatable about an axis of rotation fastened to the container mouthpiece
  • the rotary closure cap according to the invention has the advantage that, depending on its rotational position between the container mouthpiece and the cap mouthpiece, a fluid-conducting channel is opened or closed, so that the rotary closure cap can be opened or closed by simply turning it without the rotary closure cap completely from the container remove is.
  • the rotary closure cap according to the invention enables drinking via the cap mouthpiece "through the plastic closure".
  • the outlet opening extends in a circular arc in the circumferential direction of the top plate, which results in the advantage that the outlet opening is relatively long, so that a sufficiently large amount of liquid for pleasant drinking through the outlet opening can escape from the container.
  • the outlet opening is also sufficient space for the intake of air available, which enters the container, so that the inventive rotary closure cap allows a comfortable and continuous drinking.
  • the rotary closure cap is integrally formed, so that it is very inexpensive to produce.
  • the rotary cap is suitable for so-called still drinks, as well as pressurized drinks, especially carbonated drinks. Since the rotary cap has on the inside an annular circumferential, one-piece sealing lip, which in closed state rests against the inside of the container neck, and thereby achieves an excellent sealing effect, the rotary cap is particularly suitable for pressurized drinks.
  • the rotary closure cap preferably has a stop, so that the angle of rotation is limited and the rotary closure cap can not be completely removed from the container.
  • the cap mouthpiece is preferably not centrally symmetrical with respect to the rotary cap but laterally to allow a comfortable drinking.
  • the container mouthpiece has an external thread and the rotary closure cap a correspondingly adapted internal thread, so that the rotary closure cap is also raised during rotation, thereby releasing a larger passage opening.
  • the rotary cap fits on a container with standardized container neck or standardized container neck.
  • a standardized container neck is understood to mean a container neck with geometry usually prescribed by international standards. The vast majority of bottles used in the beverage industry today are provided with a standardized container neck on which a standardized rotary closure cap can be placed.
  • the mouth geometry of standardized container necked mouthpieces is defined for example in standards of the PCO (Plastic Closure Only) or BPF (British Plastics Federation).
  • the PCO mouth geometry is particularly suitable for containers with plastic screw caps. These Plastic screw caps are suitable for closing bottles with both still and pressurized carbonated drinks.
  • Such a standardized container neck, configured as a so-called PCO 28 neck is disclosed in U.S. Patent Nos.
  • FIG. 3 shown.
  • inventive rotary closure cap can according to the neck FIG. 3 adapted as PCT-28 closure with 28 mm diameter or, depending on the geometry of the neck in other standard diameters are made.
  • the rotary closure cap according to the invention for standardized container necked mouthpieces has the advantage that the bottles produced in large quantities can be easily equipped with the attractive rotary closure cap according to the invention.
  • the rotary closure cap according to the invention is preferably completely compatible with the standardized rotary closure caps hitherto used in connection with standardized container necked mouthpieces.
  • the cap mouthpiece of the rotary cap extends within the surface of the top plate perpendicular to the top plate or in the direction of rotation of the rotary cap, with the result that the cap mouthpiece does not protrude radially to the axis of rotation on the cylindrical shell of the rotary cap.
  • the rotary closure cap according to the invention is designed in one piece, there are hardly any additional costs for its production, so that a novel rotary closure system can be offered with the rotary closure cap according to the invention, which is extremely easy to operate, which conveys a novel drinking experience and which is extremely cost-effective. Because the inventive rotary cap can be placed on a standardized container mouthpiece, the Umstellisse for equipping the container with the inventive rotary closure cap are extremely low. The rotary closure cap according to the invention thus makes it possible to create substantial added value by creating, through negligibly small additional costs, an extremely attractive beverage packaging for consumers, with a standardized beverage container and the attractive rotating closure cap.
  • FIG. 1 shows a perspective view of an embodiment of a rotatable about a rotation axis D rotary cap 2 made of plastic, consisting of a cylindrical shell 2a in the basic shape and a substantially circular disc-shaped top plate 2d with a circular arc in the circumferential direction of the top plate 2d extending outlet opening 2k, wherein the outlet opening 2k is divided by a plurality of circumferentially spaced webs 2w.
