Definitions

• the invention relates to a tamper evident closure for an access opening in a container, in particular a bottle, with a closure part which is placeable onto the access opening in a sealing manner and has a bottom sleeve portion and a top cover portion, which are connected in one piece to each other via a first tamper evident indicator, and with a hood-like indicator cap which forms a second tamper evident indicator and at least partially surrounds at least the cover portion of the closure part, wherein access to the first tamper evident indicator is possible only when the indicator cap is destroyed, and wherein a tear off tab is formed in the indicator cap.
• a tamper evident closure which is at least partially destroyed during the initial opening and thus irreversibly indicates that the closure has already been opened once .
• the tamper evident closure is mounted on an upright bottle which is oriented substantially vertically and the longitudinal axis of which runs in the vertical direction, wherein the details "at the top”, “at the bottom”, “axially” and “radially” relate to this orientation of the bottle.
• the invention is not restricted to a correspondingly oriented bottle .
• a tamper evident closure customarily has a first tamper evident indicator which is formed between a cover portion, which is customarily in the form of a screw cap screwable onto the top end of the bottle, and a sleeve portion arranged there below.
• the sleeve portion sits on the bottle in such a manner that it cannot be pulled off axially therefrom. If the user rotates the cover portion or the screw cap, one piece moulded webs which, in the undamaged state, connect the cover portion to the sleeve portion inevitably break off since the cover portion is raised axially by the rotational movement and the sleeve portion cannot follow this axial movement.
• the broken-off webs serve as an irreversible indication to the user that the closure has already been opened.
• the invention is based on the object of providing a tamper evident closure of the type mentioned which can be opened in a simple and reliable manner for a user.
• the tear off tab is bounded by two grooves which are arranged at a distance and end at a distance from the bottom rim of the indicator cap, and that at least one of the grooves is assigned a breaking point which extends as far as the bottom rim of the indicator cap.
• the invention starts from the basic consideration of forming the tear off tab between two vertical grooves in the skin surface of the indicator cap, and therefore, the user has to grasp the tear off tab and pull the latter downwards, which constitutes a movement which is easy to carry out for said user.
• the tear off tab preferably extends here from the top rim of the indicator cap downwards on the skin surface thereof to shortly before the bottom rim of the indicator cap.
• the user pulls the tear off tab downwards to such an extent that the breaking point running between the bottom end of the at least one groove and the bottom rim of the indicator cap is loaded with a tensile force and tears off, as a result of which the indicator cap is interrupted or opened in the circumferential direction and can be removed from the closure part lying there below.
• both the grooves of the indicator cap can be assigned with a breaking point and each of which extends as far as the bottom rim of the indicator cap from bottom end of the respective groove.
• a breaking point In order to remove indicator cap from the closure part, when the user pulls the tear off tab downwards to such an extent that the breaking points running between the bottom end of the respective grooves and the bottom rim of the indicator cap is loaded with a tensile force and tear off. Tearing off of the breaking points results in interruption or opening of indicator cap which can be removed from the closure part lying there below.
• both the grooves of the indicator cap are of equal length.
• the indicator cap is preferably composed of an inherently stable plastic and sits on the closure part lying there below rotatably, but axially non-displaceably .
• the two grooves preferably run in the circumferential direction of the indicator cap in a manner offset from and parallel to each other in the vertical orientation, wherein it is preferably provided that the grooves in each case begin at the top rim of the indicator cap and extend vertically downwards from there.
• the breaking point at the lower end of the at least one groove can be formed by a cross-sectional weakening of the material of the indicator cap at this position and/or by a perforation.
• the tear off tab is offset radially inwards relative to the outer skin surface of the indicator cap. This affords the advantage that the user, when pulling down the tear off tab, carries out a jerk-like movement directed radially outward at the bottom end of said tear off tab in the vicinity of the bottom rim of the indicator cap, thus making it easier to tear the breaking point in the region at the bottom end of the at least one groove .
• the tear off tab formed on the wall of the indicator cap is directly grasped and pulled down by the user.
• a functional improvement is provided if, in a development of the invention, the tear off tab is connected at its top end facing away from the breaking point to a handle tab.
• the handle tab is preferably larger than the tear off tab, and therefore it can be grasped in a simple manner by users.
• the handle tab is preferably moulded in one piece onto the tear off tab and, in the starting state, can be integrated in the indicator cap and fixed therein via breaking regions which can be broken off.
• the user breaks the handle tab out of the indicator cap by destroying the breaking regions, which may be, for example, webs or perforation lines or cross-sectional weakening, folds the handle tab upwards and, at the latter, pulls the tear off tab vertically downwards .
• breaking regions may be, for example, webs or perforation lines or cross-sectional weakening
• the handle tab In an unused, undestroyed state of the indicator cap, the handle tab preferably completely or at least partially forms the upper top wall of said tamper evident seal, and therefore the handle tab is firstly easily accessible and secondly does not require any additional construction space .
• an actuating part for releasing and grasping the handle tab can be formed on the handle tab on the side facing away from the grooves.
• the actuating part is in the form, for example, of a projecting pushing edge at which the user can grasp the handle tab and lift same out of the indicator cap with the breaking regions being destroyed .
• the closure part has a bottom sleeve portion and a cover portion which is arranged there above and is connected in one piece to the sleeve portion with the interconnection of the first tamper evident indicator sits on the container under the indicator cap.
• the cover portion of the closure part is preferably in the form of a screw cap, and the bottom and the bottom of the container has a corresponding thread with which the screw cap can enter into engagement .
• the first tamper evident indicator is formed by webs via which the sleeve portion and the cover portion of the closure part are connected in one piece to each other and which inevitably break off when the cover portion is opened for the first time.
• the first tamper evident indicator is formed by a circumferential band which is bounded by two perforation lines and runs between the sleeve portion and the cover portion of the closure part.
• the circumferential band is preferably assigned a handle tab at which the user can grasp the band and can open same by destroying the perforation lines, and therefore the cover portion is released from the sleeve portion and can be removed from the container.

• the closure part 12 sits on the access opening in the bottle in a sealing manner and is fixed on the bottle in such a manner that said closure part 12 can be removed only by the destruction of the first tamper evident indicator 15.
• An indicator cap 11 is placed from above onto the cover portion 14 and the first tamper evident indicator 15 and is preferably latched to the closure part 12. In such a way that said indicator cap 11 is held fixedly relative to the closure part 12 in the direction of the longitudinal axis X and can be removed from the closure part 12 only by being destroyed.
• a circumferential rib 33 extending perpendicularly to the longitudinal axis X is provided at interior of the indicator cap 11 which is engageable with a corresponding circumferential rib 34 formed on upper part of the sleeve portion 13.
• the circumferential ribs 33, 34 provided on the indicator cap and the sleeve portion are configured so as to snap-fittingly engage the indicator cap with the closure part and to hold the indicator cap 11 fixedly relative to the closure part 12 in the direction of the longitudinal axis X.
