Definitions

  • the invention relates to a tamper-evident closure for verifying the integrity of a container closure from a closure cap which bulges over a container wall and a container opening provided in the container wall and releasably connectable to the closure cap, the closure cap in the closed state with its peripheral edge close to the loading lies or touches the container wall, consisting of at least one indicator element which is arranged in the closed state between the container wall and the closure cap, a first end of the indicator element projecting radially in the direction of the center line of the container under the closure cap and a retaining device with an upward cross has leg extending to the longitudinal axis of the indicator element, and a second end protrudes radially outward.
  • Such indicator elements have been known for a long time and serve as a checking device in order to be able to determine whether a container is in the first closed state or whether it has already been opened. Such a possibility of checking can prove to be important both from a hygienic point of view, for example in the case of foods, and from a conservation point of view, for example in the case of medicines and cosmetics.
  • the indicator elements known from the prior art are based on a common functional principle, which is based on making a previous opening of the container in the closed state of the container recognizable by separating the segments of the indicator element from one another at predetermined breaking points provided for this purpose. If the closure cap is unscrewed, the indicator elements fall out, so that it becomes clear that the closure is no longer intact.
  • Such tamper-evident closures are associated with the disadvantage that several work steps are necessary when they are attached to the container. First, the indicator element or several indicator elements must be on the container wall be placed and then the cap must be screwed on.
  • this object is achieved in that the indicator element is connected to the first end on the inside of the closure cap with at least one fastening device, and in that the fastening device is arranged at the upper end of the retaining device.
  • the inventive design of the tamper-evident closure simplifies its assembly. So only the cap has to be applied to the container. In this process, the attachment between the indicator element and the closure cap is released, so that the indicator element comes to lie between the container wall and the closure cap, but does not fall out. If the cap is loosened, the indicator element falls out.
  • the tamper-evident closure is preferably designed in such a way that in the area of the attachment the axial distance from the edge of the closure cap to the attachment is smaller than the axial distance between the edge of the closure cap and the top of the indicator element, if this is just with its maximum contact surface bears against the container wall. This ensures that the attachment breaks off as soon as the indicator element lies with its maximum contact surface on the container wall.
  • the leg prevents the indicator element from falling out before the closure cap has been fully applied and a gap between the edge of the closure cap and the top of the indicator. element exists.
  • the leg is shorter than the axial distance from the attachment to the edge of the closure cap.
  • the indicator element When the closure cap is applied to the container wall, the indicator element is clamped between the container wall and the edge of the closure cap.
  • the indicator element forms a lever arm which rotates around the point of contact which is in contact with the inner edge of the lid edge and with the upper side of the indicator element. Since the leg is shorter than the axial distance from the underside of the closure cap to the attachment point, the attachment between the indicator element and the closure cap is released when the closure cap is applied axially.
  • the indicator element lies between the edge of the closure cap and the container wall. It is either prevented from falling out by the leg or pinched between the container wall and the edge of the closure cap.
  • the indicator element is preferably attached to the inside of the closure cap by means of an attachment point. In this way, little material is required for the attachment and no great forces have to be applied to destroy the attachment when the closure cap is applied. In addition, curved indicator elements can also be fixed perfectly in this way.
  • the fastening point is preferably arranged in the lower region of the closure cap in the vicinity of the edge, so that the indicator elements on the side located within the closure cap can be realized with small dimensions.
  • this also applies to any other type of fastening if no fastening point is used.
  • the indicator element is arranged on the outside of the closure cap.
  • the indicator element must be movable from the outside to the center line of the container into the gap between the closure cap and the container wall while the closure cap is being applied to the container wall.
  • the indicator element is integrally formed on the closure cap, so that the closure cap and the indicator element are designed as a one-piece injection molded part.
  • the indicator element and the sealing cap are manufactured and sold as one component.
  • the tamper-evident closure is made of plastic.
  • Other suitable materials can of course also be used, such as. B. sheet metal.
  • the cap itself can have all common and suitable shapes. You can e.g. B. have a round, a rectangular or a triangular cross-section.
  • the closure cap in the area of the indicator element can be provided with a recess on the edge, the geometry of the recess roughly corresponding to the geometry of the indicator element. In this way, the indicator element is protected against unintentional shifting, in which this could fall out of the closure cap.
  • the tamper-evident closure can have a plurality of indicator elements which can be positioned as desired along the peripheral edge of the closure cap. If e.g. B. three indicator elements on a cap with a circular cross-section offset at angles of 120 °, is a reinsertion of the indicator elements by a single person after Opening of the tamper-evident seal excluded.
  • the total number of indicator elements is only limited by the geometry of the closure cap and the container wall. In this way, the indicator elements can also be arranged in a ring-like manner along the entire circumference of the closure cap. The geometry and the dimension of the indicator element or elements are freely selectable.
  • the closure cap can preferably be fastened to the container opening by means of a screw connection.
  • the closure cap can be fastened to the container opening by means of a bounce closure or other suitable detachable connections.
  • the tamper-evident closure according to the invention can therefore be used in all standard closures and containers without having to change the shapes for producing the containers.
  • the indicator element is expediently rounded off or beveled at the second end on the side directed in the direction of the central axis of the closure cap, which ensures that the indicator element also in the case of horizontally running container walls when the closure cap is applied to the container in the radial direction from the center line of the container ters folds outwards and comes to rest between the edge of the cap and the container wall.
  • the tamper-evident closure according to the invention can be used both for containers whose container wall protrudes radially below the closure cap, and for containers which are flush with the closure cap.
  • the tamper-evident closure according to the invention can be designed in such a way that the indicator element can be clamped in the closed state between the edge of the closure cap and the container wall. This prevents the indicator element from being pushed inwards in the radial direction or its position being changed in any other way. If, on the other hand, the indicator element is not pinched, it will fall out from below the closure cap Prevents leg of the restraint.
  • Fig. 4 is a plan view of the tamper-evident closure of Fig. 3 and
  • FIG. 5 shows a detailed illustration of an alternative embodiment of the indicator element.
  • the tamper-evident closure consists of a closure cap 1, which can be detachably attached to a container opening 3 of a container 2 designed as a socket.
  • An indicator element 4 is arranged on the inside of the closure cap in the region of the peripheral edge 11 of the closure cap 1.
  • the container 2 is provided around the container opening with a shoulder-like beveled container wall 21.
  • the container 2 with the container wall 21 and the container opening 3 is designed as a one-piece injection molded part.
  • the container opening has a thread (not shown) on the outside of its socket, onto which the closure cap 1 can be screwed with an attachment which corresponds to the thread. This connection can alternatively also be made by means of a bounce lock or other suitable detachable connections.
  • the exact structure of the indicator element can be seen particularly clearly from FIG. 5.
  • the indicator element 4 has a longitudinal leg 41 and a retaining lug 42. designed restraint.
  • the retaining lug 42 has a leg 43 running transversely to the longitudinal axis of the indicator element.
  • the indicator element 4 is fastened to the inside of the closure cap 1 at the upper end of the retaining lug with a fastening designed as a fastening point 44.
  • the closure cap 1 and the indicator element 4 are designed as a one-piece injection molded part which are connected to one another via the fastening point 44. Alternatively, this connection can also be made by means of a film joint or by other suitable means.
  • the attachment point 44 ensures, however, that the indicator element 4 can be placed correctly even with strongly curved closure caps 1.
  • the indicator element 4 has a rounded portion 45 on the side directed in the direction of the central axis of the closure cap.
  • FIGS. 1 to 3 the mode of operation of the indicator element 4 becoming clear.
  • the cap has just been applied to the container opening 3. No rotary movement for closing has yet been carried out.
  • the indicator element 4 is connected to the closure cap 1 at the fastening point 44 and hangs vertically downward. The second end of the indicator element has just come into contact with the container wall 21 on its surface in the region of the rounding 45.
  • the closure cap has been partially screwed on, so that it has shifted in the direction of the container wall 21 along the longitudinal axis of the container.
  • the indicator element has been pushed outward from the center line of the container in this process due to the rounding and the slope of the container wall 21.
  • the slope and the rounding 45 ensure that the indicator element folds outwards when it is closed, so that it is placed between the edge of the closure cap 1 and the container wall 21 becomes.
  • the underside of the longitudinal leg of the indicator element bears against the container wall 21. On the upper side of the longitudinal leg 41 of the indicator element, this touches the inner edge of the peripheral edge 11 of the closure cap 1. Since the fastening point 44 is still fastened to the inside of the closure cap 1, the further closure produces a torque around the contact point 46.
  • the indicator element 4 When the closure is turned further ⁇ cap in the closure direction, the indicator element 4 is separated from the closure cap 1 at the fastening point 44 due to the lever.
  • the retaining lug 42 ensures that the indicator element 4 does not slip out below the closure cap 1 before the container 2 is closed or the indicator element 4 is clamped between the peripheral edge 11 of the closure cap and the container wall 21. This case is shown in Fig. 3.
  • the fastening point or the fastening device must therefore be designed geometrically and in terms of the material properties in such a way that its destruction is ensured during the closing process, but does not take place before the closure cap 1 sufficiently fixes the indicator element 4.

  • the upper side of the longitudinal leg 41 of the indicator element 4 which is clamped between the container wall 21 and the closure cap 1, can be clearly seen. If the closure cap 1 is now rotated slightly in the opening direction, the indicator element falls out due to its own weight. It can be seen by third parties that the container has been opened.
  • the indicator element can of course have all suitable forms. B. be round, triangular or very long.
  • several indicator elements can be placed along the peripheral edge 11 of the closure cap 1 in order to prevent the indicator elements from being reinserted after opening.
  • the indicator element 4 is not clamped between the inner edge of the peripheral edge 11 of the closure cap 1 and the container wall when it is closed.
  • the attachment point 44 is designed here in such a way that the indicator element 4 comes to rest on the container wall 21 without the upper side of the longitudinal leg 41 of the indicator element 4 touching the peripheral edge 11 of the closure cap.
  • the peripheral edge 11 of the closure cap 1 has a recess 12 in the area of the indicator element 4, the geometry of which corresponds approximately to the geometry of the indicator element 4. This recess 12 forms an additional fixation for the indicator element 4 against displacement.
  • the tamper-evident closure according to the invention simplifies the manufacture and assembly of such closures, since the closure cap and the indicator element can be designed in one piece as an injection molded part. It is only necessary to screw the cap onto the container. An additional step for interposing the indicator elements is not necessary. The rounding at the second end of the indicator element ensures that this is also folded outwards from the center line of the container if the container wall is horizontal or the container wall is flush with the closure cap.
