The present invention relates to a wristband with a tamperproof closure. Wristband are commonly used at events for identifying attendants. It is thereby important that the attendants and the wristband remained together during the event such that at any moment the valid attendants of the attendant can be verified. A further purpose of such a wristband is discerning of permission of consuming of consumptions .

The development of suitable wristband is a continu ^¬ ing challenge. Several solutions have been devised to at ^¬ tach wristband to the wrist of a person.

The present invention serves the purpose of an im ^¬ provement of the prior art relative to attachment and pre ^¬ vention of misuse of a wristband.

This end, the present invention provides a wristband with a tamperproof closure, comprising:

- a band body forming a band that is wrappable around the wrist,

- a closure base for enclosing adjacent to that a, the wrist girdable, end part of the wristband,

- a closing element for closing in of the end part of the wristband,

- in which the closing element is suitable for coop ^¬ eration with the closure base by means of a primary con ^¬ nection to a first side of the wristband and a secondary connection at an opposing side of the first side, in which :

- the closure base is formed to the band by means of a forming operation.

An important advantage of the present invention is that an end of the band is already united with the base of the closure during manufacturing of the band. Because of this, a high degree of reliability and robustness is real ^¬ izable. Furthermore, the advantage exists that a product is manufactured that is directly usable as the wrist. Fur ^¬ thermore, this wristband is manufactured in an efficient manner by means of a forming operation in which the mutual arrangement of the band with the closure base is deter ^¬ mined by the forming operation. Furthermore, it becomes possible to realize this mutual arrangement in an auto ^¬ mated manner by directly applying of the forming opera- tion.

According to a first preferred embodiment, the form ^¬ ing operation comprises a molding operation, such as action patient. Because of this, the material of the closure base can be arranged at the band during the forming opera- tion, thereby finalizing the mutual fixation. With this, a mutual fixation between the band and the closure base is extremely reliable.

According to a further preferred embodiment, the secondary connection comprises a snap connection. It is advantageous that during placement around the wrist, the connection can be realized both very easily, quickly, and with minimal endurance or impact to the user. The click connection, is provided with application of a 2 thing, such as a single or plural toothing of a tie wrap connec- tion. This provides advantageously a reliable connection that is preferably closable but not openable.

According to a further preferred embodiment, the snap connection is a blind snap connection, preferably comprising lock in means for blindly enclosing of the snap connection. Thereby, the snap connection is not visible from the outside of the closure. Preferably, the snap con ^¬ nection is not reachable by means of a tool or insertion tool, such as a user may carry with him to an event, such as a pen or a knife.

Further preferably, the closure is formed by means of the closure base and the closing element. There with, no further parts are required for providing a fixation around the wrist of the band.

Further preferably, the primary connection comprises a hinge. An advantage of such a hinge is that fixating of the closure around the band is a simple operation by ro- tating around the hinge. There with, the mutual distances between the angel and the secondary connection are fixed. A further advantage of such a hinge is that it is preas- semblable such that closure can be realized directly at the location of use. The secondary connection is hereby preferably the snap connection.

Further preferably, the wristband according to the present invention comprises retention means for holding of the closing element relative to the closure base. With this, the band is, particularly in the longitudinal direc- tion, fixed relative to the closure. Herewith, the length of the band is fixed during closing of the closure in a visible manner.

Further preferably, the band is formed in into the closure base by means of a forming operation, such as a molding operation, such as an injection molding operation.

The retention means further preferably comprise pins, preferably pointy pins, for fixing of the band by closing of the closing element.

For the purpose of making the retention means fur- ther robust, these further preferably comprise openings formed into the closure base by means of fixation means that are applied for fixation of the band during forming of the closure base. With this, it is on the one hand achieved that the retention means are enforced by making contact against the walls of the openings. On the other hand, it is achieved that the retention means can be ar ^¬ ranged further into or through the band. This achieves a more robust fixation of the band relative to the closure.

Further preferably, band fixation means are formed at the closing element. An example thereof is retention means that are affixed to the closing element, such as em ^¬ bodied as the set pins. Preferably, the wristband fixation means of the closing element are insertable into the open ^¬ ings of the closure base.

A further aspect of the present invention relates to a method of making a wristband comprising steps of:

- providing of a mold for forming of a closure base, - arranging into the mold of a band for forming of a wristband,

- closing of the mold,

- filling of the closure base forming part of the mold with a suitable material, such as a synthetic mate- rial,

- in which the mold is provided with positioning elements for positioning of the band during the steps of billing of the mold for forming of the closure base and the band.

An advantage of this aspect according to the present invention is that a wristband according to the present in ^¬ vention is manufacturable in ways that are in line with the above described advantages.

Further preferably, the method comprises steps of arranging into the mold of an RFID unit for forming thereof into the material of the closure base. Thereby, it is preferably realized that the closure can be applied as RFID sender receiver. Thereby, becomes possible to use the closure as for example an identification and or payment means, such as especially in a close payment system of for example an event.

Further preferably, the placement of the RFID unit is performed before or after arranging of the band in the mold .

A first preferred embodiment (Fig. 1) according to the present invention relates to a wristband 1 with a clo ^¬ sure 10. It comprises a band part for that is formed in into a closure base 2. Furthermore, the closure 10 com- prises a closing element 3 that serves the purpose of locking in of a band part wrapped around a wrist. Thereby, a closed-loop is formed in which the wrist is enclosed.

The wristband is tamperproof because a first side of the end of the band 4 is locked in into the closure base during manufacturing thereof and because the closure ele ^¬ ment locks in the part of the band that is wrapped around the wrist in a simple manner and secures it in a tam ^¬ perproof way. This is tamperproof because in case of a person trying to remove the band or opening of the closure element, the closure element according to the respective preferred embodiments is damaged in a way that is easily visible. Either the closure thereof is damaged or the top surface thereof is damaged. This is explained in greater detail below.

The closure base as a bottom layer 14 and a top layer 13. The closure base as openings 11, 12 at the bot ^¬ tom side and the upside for fixating of the band part formed during manufacturing thereof. The openings are both formed in the bottom layer 14 as in the top layer 15 such that band support pins of the mold in which the closure base is manufactured fixating the band from two sides whereby the openings are formed during molding in case of molding or injection molding.

The openings 11 have a substantially cross shape. The openings 12 have a substantially line shape. A central part of the substantially cross shaped openings 11 serves the purpose of receiving fixation pins 42 for fixating an end part of the band for that is wrapped around the wrist during closing of the closure 10. Between the openings, pins 41 are arranged that extend upwardly from the top layer 13. Also these pins fixating the end part of the band that is wrapped around the wrist during closure of the closure 10.

As both sides of the Fed through band connections are present for mutually connecting of the closure base with the closing element.

At one side, in respective protrusions 21, slide in openings 18 for sliding in a hinge pins 28 of the closing element. At the side, also two retention protrusions 19 for holding into the slide in openings of the respective hinge pins. To this end, the retention protrusions provide grip to a gripping surface 39 that is preferably substan- tially cylindrical, of the closing element.

As the other side are two insertion openings 15 ar ^¬ ranged for insertion therein of fixation element 25 with hooking teeth 27 of the closing element. The hooking teeth lock onto the bridge is 17. In order to prevent opening of the closure, lock in means 26 reach at the outside of the bridges, such as lock in late 26 beyond the openings 16. These rich openings are applied for forming of the bridges during the forming process. The lock in lids serve as indicators for the function of tamperproof ring. Damaging of these lock in means or lock in lids 26 is readily dis ^¬ cernible and an indication that there has been tampering with the closure. The wristband is subsequently no longer valid.

A further indicator for tampering with the closure provides the top surface of the closing element. It is provided with two weakening lines by means of breaking lines 32 and 33. As soon as a person tries to open the lid the breaking lines will sever the integrity of the mate ^¬ rial by breaking. The wristband is subsequently no longer valid .

The invention is described relative to a wristband that is just as well suitable for fastening around another body parts.

Shown is that the hooking teeth are arranged di ^¬ rected towards the lock in lid side, or outer side. It is furthermore considered that the gripping teeth are di ^¬ rected towards the inner side or transfers thereto or ar- ranged at any angle.
