Definitions

  • the present invention refers to a screw-on closure or cap for closing a recipient.
  • the present invention refers to a screw-on cap comprising at least one detachable retention flap which can be screwed on or screwed off an outer screw thread belonging to a container for the purpose of preventing undue tampering of the contents stored inside the recipient.
  • Said sealing systems have the function of assuring the tamper-resistance of the contents stored in the recipient or container.
  • a sealing system usually includes a tamper-resistant band joined to a screw-on cap or closure.
  • Said bands just like the caps to which they are incorporated, are cylindrical and are vertically joined to the also cylindrical body of the cap or closure in the lower portion thereof and are provided with different internal stop profiles assuring, after the initial screwing on of the cap on the threaded neck of the container, the tamper-resistance of the container and its contents by means of the housing of said stop profiles arranged on the tamper-resistant bands, under a circular ring of a diameter exceeding that of the profiles provided on the threaded neck of the container after the screw thread area, which prevents it from being unscrewed without previously breaking the connections arranged for that purpose between said band and the body of the cap.
  • the effectiveness of the different existing tamper-resistant bands incorporated to screw-on caps or closures is measured upon or in the moment of the first opening of the container, a moment in which they must have enough resistance so as not to allow unscrewing the cap or closure without previously separating, by breaking, the corresponding connections joining said tamper-resistant bands to the body of the cap or closure, which determines, according to the result, the evaluation of the efficacy it affords to the manufacturer and the end consumer to trust in a given type of cap or closure or not, the tamper-resistance of which must be as evident as possible.
  • this type of sealing systems has some drawbacks resulting, for example, from the existence of a circular ring under the screw thread/screw threads on the neck of the recipient. Therefore, upon performing the screwing on operation, the stop profiles need to surpass the diameter of the screw threads of the neck of the container, and then that of the circular ring under which it must be located at the end of the run. As a result, to perform said screwing on in the filling line, it is necessary to carry out a high screw torque to assure an effective screwing on, which on many occasions cannot be specified, and on other occasions deforms the outer appearance of the screw-on cap due to an excess.
  • the tamper-resistant system of the present invention comprises a screw-on closure or cap including a retention flap and cooperates with a locking device comprised on the neck of a recipient which in turn includes a first rib and a second rib, such that in the first screwing of the screw-on closure the retention flap deviates towards the axis of the recipient in order to pass between the first rib and second rib, and in the end position of the retention flap butts against the second rib in a secure and reliable manner.
  • the tamper-resistant system of the present invention is advantageous because it eliminates the drawbacks previously set forth, those pertaining to the manufacture, those pertaining to its application in filling lines, and especially because it assures the tamper-resistance of the contents of a container before the first use.
  • An object of the invention is to develop a simple tamper-resistant system of low manufacturing cost and easy application in a filling line, and which prevents total or partial tampering of the contents stored in a recipient incorporating said tamper-resistant system.
  • Another object of the invention is to assure the existence of evidence in the tamper-resistant system in the event of an attempt to tamper with the contents of the container that is easily identifiable both by the manufacturer and by the end consumer.
  • Another object of the invention is to eliminate the tamper-resistant band of other systems so as to simplify the container recovery line in the recycling industry, since if there is no tamper-resistant band on the neck of the container to be recycled, it is possible to eliminate the tool responsible for removing said band from the neck of the recipient. It must be noted that the container and the tamper-resistant band are made of different materials, therefore they must be separated in order to be recovered.
  • Yet another object of the invention is to simplify screw-on cap manufacture and filling line application processes.
  • the screwing resistance is reduced to a maximum, allowing high accuracy and a low screw torque, which results in the effectiveness of the application or capping machines, increasing their performance and operating life.
  • Another objective of the invention is to improve the efficacy, operating life and quality of screw-on cap manufacturing processes. As a result, the manufacturing and filling system is also low-cost.
  • Figure 1 represents a retention or locking device 15, 16 located under the outer screw thread or threads 13 located on the neck 12 of a container or recipient 11.
  • the recipient 11 is preferably made of a plastic material so that the material can be injected in an injection mold.
  • the recipient 11 is suitable for storing a substance such as a liquid, a carbonated beverage or the like.
  • the retention device comprises a first projection 15 and a second projection 16 or ribs close to the contact edge 14 of each one of the two parts or halves constituting the container 11.
  • each half of the container includes a first rib 15 and a second rib 16, each one of them located at one of the contact edges corresponding to one half of the container 11.
  • the first rib 15 is in contact with the neck 12, that is, in contact with the outer face of the cylinder of the neck of the container 11 and on a horizontal base ring 17 which is located under the screw thread 13.
  • said half of the container includes the second rib 16 arranged on the base ring 17, externally and separately, and not in contact with the cylinder of the neck 12. Therefore, when the contact edges of both halves of the container are joined, two sets of locking devices 15, 16 are formed such that each one of the locking devices comprises a first rib 15 from one half and a second rib 16 from the other half of the container 11.
  • both ribs 15, 16 are facing at the same height on the base of the neck 12 and on the base ring 17 of the container 11, radially displaced from one another in order to prevent a retention flap 33 belonging to a screw-on cap or closure 31 from being radially displaced towards the axis of the container 11 when said cap 31 is unscrewed for the first time.
  • the retention flap 33 cannot be radially displaced towards the axis of the container 11, said movement is prevented by the first rib 15 which is in contact with the neck 12 of the container 11.
  • the first rib 15 comprises a deviation bevel on the introduction side, that is, the side closest to the contact edge 17, acting in the screwing on direction such that when the screw-on 31 cap is screwed on, the retention flap 33 is radially deviated outwardly from the axis of the container 11, being able to pass between the outer face of the neck and the concave inner face of the second rib 16 in the first screwing on of the cap 31.
  • the first rib 15 has the purpose of limiting the radial run of the retention flap 33 towards the axis of the container 11 in the final closure position for the screw-on cap 31 once the latter has been located after the first screwing on, and thus preventing the cap 31 from becoming unscrewed without tampering or previously detaching said flap 33, for example by breaking a breakable bridge or tear strip 34 and/or a film hinge 35 by means of which the retention flap is joined to the skirting or sleeve of the cap 31.
  • the tear strip 34 is located on the side opposite to the hinge 35.
  • the first rib 15 extends like a circular arch-shaped curb along one part of the contour of the neck 12 of the container 11, that is, in contact with the outside of the neck of the container, and on the horizontal base ring 17.
  • the second rib 16 is molded on the base ring 17 in a pyramidal quasi-triangular wedge shape along one part of the contour of the base ring 17 such that its concave inner face is arranged with a predetermined spacing regarding the outer face of the neck 12 of the container 11.
  • the inner face of the second rib 16 acts in the screwing on direction such that when the screw-on cap 31 is screwed on, the retention flap 33 is radially deviated towards the axis of the container, being able to pass between the outer face of the neck 12 and the inner face of said second rib 16 in the first screwing on of the cap 31.
  • Figure 3 shows the position of the closure 31 after the first screwing on the neck 31.
  • the screw-on cap is molded in a thermoplastic material, in a single piece, suitable for being used in cooperation with the locking device 15, 16 in a tamper-resistant system preventing illicit tampering of the contents stored in the recipient 11.
  • the screw-on cap 31 comprises a cap bottom and a cap sleeve or skirt 32 with an internal threading, not shown, so that the cap 31 can be screwed on and off the outer screw thread/threads 13 belonging to the neck 13 of the recipient 11.
  • the retention flap 33 is molded in the lower end area of the cap sleeve 32 such that it outwardly projects, being oriented approximately tangentially in the cap sleeve 32, as is seen in Figures 3 to 6.
  • the retention flap 33 projects from the cap sleeve 32 opposite to the screwing on direction.
  • the retention flap can be separated and easily molded on the skirt 32 of the screw-on cap.
  • the screw-on cap 31 with the retention flap 33 can be easily manufactured unitarily in a single piece from a low-cost material, such as plastic, which has a suitable flexibility allowing the flap 33 to pass between the neck 13 and the second rib 16 after the first screwing on.
  • the retention flap ends on its front face in a stop surface which is oriented approximately radially, whereas the end of the second rib 16 located in the unscrewing direction forms a contact surface which is likewise oriented approximately radially, such that after the first screwing on of the cap 31, both surfaces are in contact for the purpose of preventing the unscrewing of the cap 31.
  • the retention flap 33 When the cap is unscrewed for the first time, the retention flap 33 must be radially displaced outwardly since the second rib 16 prevents it from being radially displaced inwardly, therefore the flap 33 is completely or partially detached and entails that the tear strip 34 and the hinge 35 have been broken. Therefore, the end consumer and/or manufacturer have proof that the container has been opened by them. In another case, the cap shows proof of prior tampering and therefore the end consumer may suspect that the contents of the container 11 have been altered.
  • the retention flap 33 may include a deviation bevel on the inner face acting in the unscrewing direction such that it facilitates the unscrewing action of the screw-on cap 31.
  • the retention flap 33 In the first unscrewing, the retention flap 33 is radially deviated outwardly of the container 11, breaking the tear strip 34 and furthermore, it will also cause the complete or partial breakage of the film hinge 35 on the retention flap 33, being able to pass over the outer convex face for the second rib 16 after the first unscrewing of the cap 31.
  • the retention flap 33 projects from the sleeve 32 of the cap 31 such that in the retained position it partially and reliably covers with its stop surface the contact surface of the second rib 16 so as to maintain a safe retention joining acting only in the direction for the first unscrewing of the screw-on cap 31.
  • a braking means 36 can be molded such that it projects outwardly from the axis of the cap 31 with a trapezoidal shape on the lower edge of the sleeve 32 of the cap 31, at a predetermined distance from the stop surface of the retention flap 33 in the screw-on direction so that the cap 31 can be stopped appropriately after the first screwing on, that is, contact between the stop surface of the flap 33 and the contact surface of the second rib (16) is assured.
  • the number of retention flaps 33 can vary according to the number of screw threads of the neck 12 of the container 11, such that a single screw thread will have a single retention flap 33 on the cap 31, a releasable and elastic flap, and one or two for retention flaps 51 fixed on a circular tamper-resistant band 52 like those currently existing.
  • a neck with two threads will have two or four fixed retention flaps 51
  • a neck with three threads will have two, four or six fixed retention flaps.
  • two retention devices 15, 16 on the base ring 17 separated 180° from on another are enough, as a result, the fixed retention flap act in twos.
  • the cooperation of the retention flap 33 and the locking device 15, 16 acts such that it necessarily facilitates its passing and coupling of the cap 31 in the screwing on direction and, by means of the controlled run of the threading on the neck 12 of the container 13 and at its end, it is made to necessarily coincide at one previously determined point, facing them at their flat surfaces, which will prevent its unscrewing from the very start of the unscrewing run and as a result will fully assure that the contents of the container have not been unduly tampered with, and it further facilities outer, easily detectable evidence of an illicit tampering of the cap.
