Definitions

  • the present invention relates to a resealable drinking cap for a beverage bottle, with an outer part which has a lower fastening portion which holds the closure on egg nem bottle neck of the beverage bottle, and an upper lid portion, the lid portion via a hinge from a closed position in a open position is pivotally connected to the fastening portion, and with an inner part which has a pouring spout with a drinking opening and a sealing edge which can be connected to the opening edge of the drinks bottle, the pouring spout forming a fluid connection between the interior of the drinks bottle and the drinking opening, and wherein the inner part is arranged within the outer part in such a way that the cover section in the closed position surrounds at least a section of the pouring spout in the manner of a protective cap and closes the pouring spout.
  • Such a drinking cap is described, for example, in WO 2017/025692 A1.
  • the fastening section of the outer part is used to fix the pouring spout, which is also referred to as a drinking insert or in English as a spout, and the closure as a whole on the bottle neck.
  • Such drinking caps are also referred to as “sport caps” and are usually attached to drinking bottles from which a consumer or user of the drinking bottle can drink directly.
  • sportscap comes from the fact that such closures and drinking bottles are often used during sporting activities, e.g. Cycling and hiking, are carried along, whereby the user can hold the drinking bottle with one hand and lift off the lid section with a finger of the same hand, the mouth or the teeth or fold it up over a hinge and then drink from the pouring spout thus exposed, without for example, to use the other hand that controls a vehicle, for example.
  • the drinking bottles typically have a cylindrical bottle neck with or without an external thread and the pouring spout of the inner part is usually on the edge of the bottle neck placed and typically sealed against the inside of the bottle neck, while the fastening section engages around the bottle neck together with the inner part placed on it and, for example, engages with an external thread on the bottle neck and thus holds the inner part and thus the entire drinking cap on the bottle neck.
  • the fastening section then has a corresponding internal thread, but snap-edge connections between the beverage bottle and the drinking cap or fastening section would also be conceivable.
  • a certain content for example an isotonic fruit juice and / or sugar solution, which is particularly useful for longer sporting activities and endurance sports Athletes are often used to take in fluids, salts and carbohydrates in good time before an otherwise impending decline in performance.
  • Drinking caps that are used for beverage bottles filled by the manufacturer in this way generally have a so-called guarantee function, i.e. The outside of the closure can be seen to determine whether it has already been opened or is still unopened, so that it is ensured that the content is unadulterated and corresponds exactly to what the manufacturer and bottler filled and which is described accordingly on a label on the bottle.

  • Corresponding guarantee elements are usually easily tearable connections between the cover section and the fastening section, which tear when the cover section is folded up to reveal the drinking opening, the cover section remaining connected to the fastening section via a hinge.
  • These easily tearable connections which serve as guarantee elements, must therefore be arranged in an area outside the hinge between the cover section and the fastening section. As a rule, they are arranged diametrically opposite the hinge between the fastening section and the cover section.
  • the present invention is based on the object of creating a resealable drinking cap of the above-mentioned type in which it is easily visible at any time after the first opening that this drinking cap has already been opened.
  • the outer part has a guarantee tab which is articulated radially pivotable on one of the sections, fastening section or cover section and which is held at a first distance from the other section by an easily tearable connection prior to opening for the first time is, but the guarantee tab is so under tension that after the initial opening and the associated separation of the easily tearable connection under the influence of this bias in ra dialer pivoted and the first distance of the guarantee tab to the other section in the closed position again increases to a second distance, so that a gap that extends in the radial direction and is larger than the previous state is created between the guarantee tab and the respective other section.
  • the limitation of this guarantee function to a guarantee flap that extends only along a small part of the circumference of the drinking cap has the advantage that such a guarantee flap can be designed to be relatively easy to move radially, in contrast to the circumferential edge areas of the cover section and outside this guarantee flap Fastening section that are inevitably close to each other when the drinking cap is closed.
  • the radially protruding guarantee tab ensures that at least in one segment of the circumference there is a clear distance between the guarantee tab and the section previously connected to the guarantee tab via at least one easily tearable connection.

  • the guarantee tab can be linked to the cover or to the fastening section via a film hinge, which can also be interrupted.
  • the easily tearable connection is preferably an axial connection and is arranged axially opposite the film hinge.
  • the guarantee tab Since the guarantee tab is hinged to one of the two parts, the cover section and / or the fastening section, i. is articulated to this part and is otherwise under radial pretension, it must necessarily pivot under the influence of the pretension in the radial direction after the easily tearable connection has been separated, so that a greater radial distance between those parts of the guarantee tab which were previously over easily tearable Connections were connected to the other part, from the corresponding part of the other section.
  • the guarantee flap a biasing radially outwards so that the free end of the guarantee flap is removed from the closure, i. from the outside of the fastening section and the cover section, folds away radially outward.
  • this radial prestress is generated by a radius that is enlarged in at least one circumferential section on the outside of the inner part, which is opposite the guarantee tab.
  • a radially outwardly directed prestressing of the guarantee tab is generated by an area on the inside of the guarantee tab which has a smaller radius (relative to the radius of the opposite inner section).
  • the at least locally enlarged outer radius of the inner part or the smaller inner radius of a section of the guarantee tab when the outer part and inner part are assembled, cause the guarantee tab and an opposing section of the inner part to engage with one another in the area of the diameter difference, generating the radial prestress.
  • the transition area from the guarantee tab to the section to which the guarantee tab is hinged has a smaller wall thickness than the areas of this section and the guarantee tab adjoining the transition area, so that a film hinge (a film hinge ) is provided, which allows the guarantee tab to be pivoted radially.
  • a film hinge should be understood to mean both a continuous area of lesser wall thickness, that is to say a continuous film hinge, and an area of lesser wall thickness interrupted by gaps, that is to say several film hinge sections separated by gaps.
  • the preload is generated in that the guarantee tab of the outer part has a bead protruding radially inward, in the direction of the longitudinal axis.
  • the longitudinal axis is defined jointly by the bottle neck and the fastening section.
  • the bead can in particular be designed as an area of the guarantee tab which is a section bent radially inward through the guarantee tab in axial cross section, preferably in the vicinity of the film hinge which permanently connects the guarantee tab to the cover section or the fastening section.
  • the bead must protrude inward so far that the radial distance of the bead from the longitudinal axis (radius) is smaller than the radial distance from the longitudinal axis (radius) of the area of the outer part directly opposite the bead.
  • the bead and the section opposite it are then pressed together while generating an elastic pretension, so that a radially outwardly directed compressive force acts on the bead and thus on the guarantee tab.

  • the bottle neck and the fastening section generally define a common longitudinal axis, the minimum distance between the guarantee tab and the respective other section in the closed position of the cover section in a cross-sectional plane containing this longitudinal axis and a point on the guarantee tab, which does not run through an easily tearable connection the initial opening is at least 1.5 times, preferably 1.8 times to 3 times greater than in the closed position of the cover section before the first opening.
  • the guarantee tab is an elongated, rectangular band in a top view, which has a height H and a width B, the width B being measured in the circumferential direction of the drinking closure and the height H in the closed position before the first opening parallel to the longitudinal axis is measured.

  • the circumferential angle over which the guarantee tab extends ie the width, should not be significant make up more than 30 ° of the circumferential angle and could also be a little less, in order not to make the radial outward folding away of the guarantee flap unnecessarily difficult, since the guarantee flap runs along an arc and its free edge when folded over outwards necessarily comes under tensile stress, while the film hinge comes under compressive stress.
  • These corresponding prestressing forces have to be overcome by the radially outwardly directed prestressing between the bead and the opposite section when the cover section is separated from the fastening section for the first time.
  • the guarantee tab has a height of at least 3 mm, preferably at least 5 mm and a circumferential extension between 5 ° and 45 °, preferably between 5 ° and 30 ° and particularly preferably between 10 ° and 20 ° in the circumferential direction.

  • a guarantee tab which had a curved shape in the non-assembled state of the outer part and inner part, is brought into an approximately flat shape by the holding force.
