Description

The present invention relates to a thermosensitive product temperature control device capable of indicating that at least one temperature threshold has been reached or crossed.

It relates more particularly to a temperature control device of the type comprising: a base in the form of a housing provided on at least one of its walls with a viewing window and, borne by the base, at the less a temperature threshold component in the form of a bimetallic plate deformable under the effect of the temperature from a first so-called initial position to a second so-called deformed position when the temperature threshold of said component is reached or crossed at least one first information carrier and one additional information carrier, each additional information carrier, associated with a component, being, in said active state of the device, mounted relative to the base, slidably movable from a position spaced from said first information carrier to a position at least partially overlapping the first information carrier under the action of a change in shape of said associated component for the passage of the device from a first configuration in which only the information carried by the first information carrier is fully readable from outside the base, to a configuration in which the information carried by the or at least one of the additional information carriers are readable from outside the base. Such a temperature control device affixed directly to the product makes it possible in particular to verify that the cold chain has been respected during storage of the product sensitive to temperature variations, in particular when the product is a pharmaceutical or food product. The use of deformable component under the effect of temperature, when a predetermined temperature has been crossed or reached for the realization of temperature control device, is known from the state of the art. However, the resulting temperature control device is considered unreliable and too restrictive. Indeed, there is no way to ensure that the deformation of the component did not occur during storage of the device before use due to exposure of the device to a non-compliant temperature. It is therefore imperative to take care that the device is, before use, stored at a temperature compliant, otherwise the risk of never signaling that a temperature threshold has been reached or crossed. Such storage conditions are not always possible. An object of the present invention is therefore to provide a temperature control device of the aforementioned type whose design eliminates storage under predetermined conditions during the entire period preceding its use. Another object of the present invention is to provide a control device of the aforementioned type whose design allows a simplified embodiment of the device, allowing rapid adaptation to a large number of temperatures or temperature ranges. To this end, the subject of the invention is a device for controlling the temperature of a thermosensitive product capable of indicating that at least one temperature threshold has been reached or crossed, said device comprising: a base in the form of a housing provided on at least one of its walls with a viewing window and, borne by the base, - at least one temperature threshold component in the form of a deformable bimetallic plate under the effect of the temperature from a first so-called initial position to a second so-called deformed position when the temperature threshold of said component is reached or crossed, at least one first information carrier and an additional information carrier, each information carrier additional, associated with a component, being, in said active state of the device, mounted relative to the base, movable to slide from a position separated from said first support information to a position at least partially overlapping the first information carrier under the action of a change of shape of said associated component for the passage of the device of a first configuration in which only the information carried by the first support information is fully legible from outside the base, to a configuration in which the information carried by the or at least one of the additional information carriers is readable from outside the base, characterized in that the device further comprises, carried by the base, for each component, means for arming or resetting said component, mounted via movable driving means, irreversibly, from a first to a second position, each component being, in a deformed position, disposed on the trajectory followed by its arming or rearming means during their transition from the first to the second position, said arming or resetting means of a component being, in the deformed position of said component, active by bearing contact on said component during their passage from the first to the second position for the return of said component to the initial position. Thanks to the presence of these means of arming or rearming, it is possible, just before use of the device, to bring or bring back, if necessary, the component in the initial position to ensure a subsequent deformation under conditions of predetermined temperature. It should be noted that the means are arming means when the component is, at the time of manufacture of the device, introduced into a deformed position in the casing and reset when the component is, at the time of manufacture of the device, introduced in initial position in the housing.

The device may comprise a single additional information carrier and a single component associated with said additional information carrier. However, preferably, the additional information carriers on the one hand, and the components on the other hand, are each at least two in number, each component has a temperature threshold distinct from one component to another, and said components are each able to be associated with an additional information medium distinct from one component to another. Thus, the device is able to control the respect of a temperature range. Preferably, in the active state and in the first configuration of the device, each additional information medium, positioned in the juxtaposed or superimposed state with a component associated with it, and disposed away from the first information medium, is retained. in said position spaced by bearing against a retaining stop preferably internal to the housing and in that each additional information carrier is releasable from its bearing position against said retaining stop via said associated component, during the deformation of said component, and is slidably movable from the spread position to a position at least partially overlapping the first information carrier under the action of active return means against the retaining stop.

Preferably, the associated component through which the additional information carrier is releasable from its bearing position against said retaining stop during the deformation of said component is made in one piece with the retaining stop. This results in a simplification of the whole.

In other words, preferably, the retaining stop of an additional information carrier is formed by a part of the component associated with said additional information carrier.

Preferably, each information carrier is in the form of a plate coated on at least one of its faces with information. Preferably, the information of the first information medium forms a bar code, also called the first barcode, and the information of each additional information medium forms, alone or in cooperation with the information of the first information medium, a barcode different from the first barcode, and the barcode of the first information medium and the barcode of the or each additional information medium comprise at least two types of information corresponding to one, to a product identification code 10, the other, a quality status code, the product identification code being identical from one information medium to another. Due to the fact that only one barcode can be read at a time, any risk of reading a barcode in place of another is avoided. Due to the fact that the bar code of the first information carrier and the bar code of the or each additional information medium comprise at least two types of information corresponding, one to a product identification code, the other to a quality status code, the risk of incorrect association of identification information and information relating to the quality of the product is reduced or even zero. The bar code of the first information medium and the bar code of the or each additional information medium therefore each comprise at least two types of information each formed by a marking, one of the types of information formed by one of the markings corresponding to a product identification code, the other of the types of information formed by the other marking corresponding to a quality status code, the product identification code formed by one of the markings being identical from one information carrier to another. As already mentioned above, preferably, each information carrier is in the form of a plate coated, on at least one of its faces, with information capable of forming the bar code of said information support. The production of the or each information medium in the form of a plate coated on at least one of its information faces capable of forming the bar code of said information carrier facilitates the modification of the barcode according to products, said barcode being in the form of a simple printed label affixed to said plate. Preferably, the device further comprises, carried by the base, for each additional information carrier, a stopper and manual drive means in displacement of said stopper between an active position, in which it is disposed on the path capable of being followed by said additional information carrier as it passes from the spaced apart position to the at least partially overlapping position of the first information carrier and prevents or limits the movement of said carrier of additional information, and an inactive position in which it is disposed out of the trajectory adapted to be followed by said additional information carrier during its passage from the spread position to the at least partially overlapping position of the first information carrier and authorizes said displacement, the active state of the device corresponding to the state in which all the stops are in the inactive position, the manual drive means in displacement of a stop stop being at least partially common to the drive means in movement of the arming means, or resetting, a component. Thanks to the presence of this stopper acting as a means of locking the additional information carrier in a position apart from the additional information carrier of the first information medium, any risk of sliding displacement of the presentation support of additional information from the position deviated from the first information carrier to the at least partially overlapping position of the first information medium is prevented, including during deformation of the associated component resulting from exposure to a non-thermal temperature. during the storage or transport phase of the device before use.

In addition, the fact that the manual drive means in displacement of a stop stop are at least partially common to the moving drive means of the arming or resetting means of a component allows, in parallel with activating the device, arming or resetting the components.

Preferably, for each component, the arming or resetting means comprise a plate disposed juxtaposed or superimposed with said component and a pusher carried by the plate, said tongue-type pusher being deformable by bearing contact with a surface of support supported by the base during the passage of said arming means or rearming of the first to the second position, said pusher being, during its deformation, able to be active by pushing on said component in the direction of a deformation said component from its deformed position to its initial position. Preferably, the support surface of the base is in the form of a ramp with an upward slope, that is to say with a slope oriented in the direction of a displacement of the pusher towards the center of the housing during the passage of the reset means from the first to the second position. Preferably, the pusher gate plate of the arming or resetting means of a component further carries the stop of the additional information support associated with said component. Preferably, the pusher gate plate means for arming or resetting a component and the plate of the first information carrier are common.

This results in a simplification of the whole. Preferably, the drive means for moving the arming or rearming means from the first to the second position are formed by a part of the arming or rearming means, projecting from the base casing, in first position. said arming or resetting means, this protruding part being able to pass from an output position of the casing to a position at least partially retracted into the casing for the passage of the arming or rearming means from the first to the second position.

Preferably, the device further comprises means for at least partial masking of the information carried by at least one of the information carriers and relative displacement drive means of the masking means and at least one information carriers from a configuration in which the information carried by each of the information media is not readable in their entirety from outside the database to a configuration in which the information carried by at least one of the media information is fully readable from outside the base, said relative displacement drive means being at least partially common to the drive means in movement of the arming means or rearming. In a first embodiment of the invention, said masking means comprise, by additional information medium, a mask, and the relative displacement driving means of the masking means and at least one of the supports. of information comprise, for each mask, a manually actuated drive member moving the mask from a so-called active position where said mask hides at least part of the information of the first information medium to a so-called inactive position where the information masked by said mask in the active position is discovered.

As a variant, the first information medium can be displaced irreversibly from an inactive position in which the first information carrier partially projects from the base and moves in the direction of the inside of the base. the information it carries is unreadable in its entirety from outside the base, to a so-called active position in which the information carried by said first information medium is readable in their entirety from outside the base. The masking means are formed by the part of the cover housing of the first information carrier in said inactive position of the first information carrier, and the drive means in relative displacement of the masking means and at least one one of the information carriers are formed by the part of the first information carrier projecting from the housing in the inactive position of the first information carrier, this protruding part forming a manual drive member for driving the first carrier of information from its inactive position to its active position.

The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which: FIG. 1 represents an exploded perspective view of the elements constituting it of a device according to FIG. the invention; Figure 2A shows a perspective view of the housing in the non-active state of the device; FIG. 2B represents a perspective view of the active device case of the device; - Figure 3A shows a perspective view of the housing body in the open position; FIG. 3B represents, in top and bottom views, the pusher carrier support plate of the arming or reset means; FIG. 3C represents, in top and bottom views, an additional information carrier; FIG. 4A shows a perspective view of the casing body in the state inserted into the casing, the first information carrier and arming or resetting means; FIG. 4B represents a perspective view of the casing body in the state inserted in the casing of all the information carriers; - Figure 5 shows a sectional view of the housing in the deformed position of the component; FIG. 6 represents an exploded perspective view of the elements constituting it of another embodiment of a device according to the invention; FIG. 7A represents a perspective view of the housing in the non-active state of the device of FIG. 6; FIG. 7B represents a perspective view of the device's active state of the device; Figure 8A shows a perspective view of the housing body in an open position; FIG. 8B represents, in views from above and from below, the pusher carrier support plate of the arming or resetting means; FIG. 8C shows, in top and bottom views, an additional information carrier; Fig. 9A shows a perspective view of the casing body in the inserted state of the casing, the first information carrier, and arming or resetting means; FIG. 9B represents a perspective view of the casing body in the state inserted into the casing of all the information carriers; FIG. 10 represents a sectional view of the housing in the deformed position of the component. As mentioned above, the device 1 for temperature control of thermosensitive product object of the invention comprises a base 2. This base 2 affects in the example shown the form of a housing comprising a body and a cover. This casing of parallelepipedal general shape is provided on at least one of its walls shown at 11 to the figures of a viewing window. The wall of the housing opposite to that carrying the viewing window 10 is shown at 12 in the figures.

This box houses a first information carrier 3 and two additional information carriers 5. The information of the first information medium 3 forms a bar code, also called the first barcode, and the information of each additional information medium here only forms a barcode different from the first barcode. The bar code of the first information medium 3 and the bar code of the or each additional information medium 5 comprise at least two types of information corresponding to one, to a product identification code, the other , a quality status code, the product identification code being identical from one information medium to another.

It should be noted that by barcode means indifferently a linear code, a 2D code or a matrix code, the barcode having the characteristic of being able to be read by an optical reader. In the examples shown, the device comprises in each case two additional information carriers, since the device is intended to indicate that a product has been maintained within a temperature range. Of course, when the device is intended only to indicate that a temperature has been reached or crossed, only one additional information carrier is provided.

In the examples shown, the first information carrier 3 and the additional information carriers 5 are each in the form of a plate coated on one of its information faces able to form the bar code of said carrier. information. The first information medium 3 is disposed between the additional information carriers 5 in the idle state of the device 1 and in the active state of the device when the temperature thresholds to be controlled have not been reached or exceeded. In the example shown in FIGS. 1 and 4B, the bar code 4 of the first information medium 3 corresponds to the digital content 764339898605 with the series 8 of digits 7643398986 corresponding to the product identification code and the series 9 of digits 05 corresponding to the quality status of the product, in this case, here, to the fact that the temperature threshold is not exceeded. The bar code 6 of one of the additional information carriers 5 corresponds to the digital content 764339898608 with the series 8 of digits 7643398986 corresponding to the product identification code and the series 9 of digits 08 corresponding to the quality status of the product, in this case, here, the fact that the temperature threshold + 8 ° C has been crossed. The bar code 6 of the other additional information medium corresponds to the digital content 764339898602 with the series of digits 7643398986 corresponding to the product identification code and the series of digits 02 corresponding to the quality status of the product, in this case here, the fact that the temperature threshold + 2 ° C has been crossed. All of these additional information carriers are housed within the housing formed by the base 2 of the device. The control device further comprises, carried by the base 2, at least one component 7 may deform under the effect of temperature, when the temperature threshold associated with said component 7 is reached or crossed. The device comprises as many components 7 as additional information carriers. In the example shown, the device therefore comprises two components 7 each associated with an additional information support 5.

Each component 7 has a temperature threshold distinct from one component to another. Each component 7 is in the form of a bimetallic plate capable of deforming from an initial position to a deformed position, under the effect of the temperature, when the temperature threshold of said component 7 is reached or crossed. In the example shown, this plate is bent along a first radius of curvature and reverses its curvature when the temperature threshold of said component is reached. Equivalently, this plate could have been flat and bend when the temperature threshold is reached or crossed.

Each additional information support associated with a component 7 is, in the so-called active state of the device, mounted with respect to the base 2 that is displaceable by sliding from a position spaced from said first information support 3 to a recovery position at less partial of the first information carrier 3 under the action of a change of shape of said associated component 7 for the passage of the device 1 of a first configuration, in which only the information carried by the first information carrier is integrally readable from outside the base, to a configuration, wherein the information carried by the or at least one of the additional information carriers is readable from outside the base.

Thus, in first configuration, the first information carrier 3 is, with its barcode 4, facing the viewing window 10 and each additional information carrier 5 positioned in the juxtaposed or superimposed state with a component 7 associated with it, disposed spaced apart from the first information support 3 and retained in said position spaced by bearing against a stop 13 retaining internal housing, that is to say housed inside the housing. Each additional information support 5 is releasable from its bearing position against said retaining stop 13 via said associated component during deformation of said associated component 7 and is slidably movable from the spread position to a lapped position at least partially of the first information support 3 under the action of a means 14 of active return against the abutment 13 retaining. To facilitate sliding movement of each additional information carrier within the housing, the housing may be provided with a rail along which each additional information carrier is slidable. Since each component 7 is associated with a different temperature threshold from one component to another, each additional information carrier 10 is movable independently of the other additional information carrier. The retaining abutment 13 is in this case realized each time as a single piece with the component 7 associated with the additional information support 5 that it retains. In this case, this retaining stop 13 is here formed by one of the edges of the constituent plate of the component 7. This edge bears against a stud 52 fitted to one of the faces of the plate constituting the support 5 additional information. When the component 7 deforms under the effect of the temperature, this support is released and allows the additional information support 5 to slide to be positioned on the first information carrier and make its barcode visible from the outside the base, through the viewing window of the housing. In a manner characteristic of the invention, the device 1 further comprises, carried by the base 2, for each component 7, means 18 for arming or resetting said component 7, mounted via means 23 to 25. moving drive irreversibly moving from a first to a second position, each component 7 being, in deformed position, disposed on the path followed by its means 18 of arming or rearming when they pass from the first to the second position said means 18 for arming or resetting a component 7 being, in the deformed position of said component 7, active by bearing contact on said component 7 during their passage from the first to the second position for the return of said component 7 in the initial position. The device 1 further comprises, carried by the base 2, for each additional information support 5, a stop 17 and manual drive means in displacement of said abutment 17 stop between an active position, in which it is disposed on the path adapted to be followed by said additional information support 5 during its passage from the spaced apart position to the at least partially overlapping position of the first information support 3 and prevents or limits the movement of said support 5 additional information, and an inactive position in which it is disposed out of the trajectory adapted to be followed by said additional information support 5 during its passage from the spread position to the at least partial overlap position of the first 3 support information and allows said displacement, the active state of the device 1 corresponding to the state in which all stops 17 stop are in the inactive position, the manual drive means for moving a stop stop 17 being at least partially common to the means 23 for moving the means 18 for cocking or resetting a component 7 .

For each component 7, the means 18 of arming or rearming comprise a plate 19 arranged juxtaposed or superimposed with said component 7 and a pusher 20 carried by the plate 19. Said pusher 20 of the tongue type is deformable by bearing contact with a bearing surface 21 carried by the base 2 during the passage of said means 18 for arming or rearming the first to the second position. Said pusher 20 is, during its deformation, able to be activated by pushing on said component 7 in the direction of a deformation of said component 7 from its deformed position to its initial position.

In the example shown in Figures 1 to 5, a plate 19 is superimposed on each component 7 and the pusher 20 is formed by a cutting of the plate 19. In the example shown in Figures 1 to 5, the constituent tab of the pusher is provided at its free end with a bulge which forms, by cooperation with the ramp of the surface 21, once the latter has passed, a non-return stop of the arming or rearming means capable of preventing a movement of means 18 arming or rearming from the second position to the first position, therefore the displacement is said to be irreversible.

The drive means 23 for moving the arming or resetting means 18 from the first to the second position are formed by a part of the arming or resetting means, projecting from the base casing, in the first position of said arming or resetting means, this protruding part being able to pass from an output position of the casing to a position at least partially retracted into the casing for the passage of the means 18 for arming or rearming the first to the second position. The drive means 23 for moving the arming or resetting means 18 comprise a tongue formed by a projecting part of the pusher carrier support plate 20, this tab being disposed at least partially projecting from the housing in the first position of the means 18 for arming or resetting, and at least partially retracted into the housing in second position of the arming or resetting means.

When the device comprises two additional information carriers, it is necessary to act on two tabs, to activate the device in the example shown in Figures 1 to 5. The support plate 19 pusher carrier 20 constituting the means 18 of arming is made in one piece with the abutment 17 stop and is housed in the housing in the superimposed state or juxtaposed with an additional information support 5 and a component 7. The stack is at the time of manufacture of the device, made so that the support plate adjoins the wall of the housing opposite to that provided with the viewing window and is covered with the component which itself is covered with additional information support 5. In the example shown in FIGS. 6 to 10, the pusher carrier support plate 20 of the arming or resetting means 18 is common to the plate constituting the first information support 3 and carrying the abutment stopper 17. to form a single piece. Consequently, independently of the embodiment chosen, the pusher plate 19 of the means 18 for arming or resetting a component 7 further carries the stop 17 for stopping the additional information medium associated with said component. In the example shown in FIGS. 6 to 10, the pusher carrier plate 20 of the means 18 for setting or resetting a component and the plate of the first information carrier 3 are common. Again, in this embodiment, each pusher 20 is a tongue-like pusher formed by an outgrowth of the pusher plate 19. In the same way as previously described, the bearing surface 21 carried by the base is in the form of a ramp disposed on the internal face of the wall of the housing opposite that equipped with the viewing window. This ramp forms an inclined slope in the direction of a driving movement of the pusher 20 of the tongue type towards the center of the housing during the passage of the means 18 of arming or rearming the first to the second position. Once the ramp has been crossed, the pusher 20 is blocked behind the ramp as shown in FIG. 10 and any displacement in the opposite direction of the arming means 18 from the second position to the first position is prevented, which is why the displacement is said to be irreversible.

The drive means 23 for moving the arming or resetting means 18 from the first to the second position are formed by a part of the arming or resetting means, projecting from the base casing, in the first position of said arming or resetting means, this protruding part being able to pass from an output position of the casing to a position at least partially retracted into the casing for the passage of the means 18 for arming or rearming the first to the second position.

The drive means 23 for moving the arming or resetting means 18 comprise a tongue formed by a portion projecting from the pusher carrier support plate, this tongue being disposed at least partially projecting from the housing in the first position of the means 18. arming or resetting, and at least partially retracted into the housing in second position of the arming or resetting means. Unlike the embodiment of FIGS. 1 to 5, since the pusher stage carries two pushers each active on a component, it is necessary to act on only one tongue to activate the device. The device further comprises means 15 for at least partial masking of the information carried by at least one of the information carriers and means 16 for driving relative movement of the masking means 15 and at least one information carriers from a configuration in which the information carried by each of the information media is not readable in their entirety from outside the database to a configuration in which the information carried by at least one of the media information is fully readable from outside the base, said relative displacement drive means 16 being at least partially common to the drive means 23 for moving the means 18 for arming or rearming. As shown in FIGS. 1 to 5, the masking means 15 comprise, by additional information support, a mask 151 and the drive means 16. relative movement of the masking means and the information carrying means comprise, for each mask, a member 161 manually actuated for moving the mask 151 from a position, said active, where said mask 151 conceals at least a part information from the first information carrier 3 to a position, said inactive, where the information masked by said mask 151 in the active position is discovered.

The active state of the device 1 corresponds to the state in which all the masks 151 are in the inactive position. Each mask 151 is here in the form of a plate provided with a tab-like protrusion forming the active part of the mask. This active part of the mask overlaps with at least a portion of the first non-activated bar code of the device. The member 161 to manually actuate movement of the mask is formed by a tab equipping the constituent plate of the mask. This tongue is arranged projecting from the housing in the inactive position of the mask. The tongue is at least partially retracted into the housing in the active position of the mask.

The user therefore provides at least partial retraction of the tongue into the housing during the activation of the device. When the device comprises a single additional information carrier, only one mask is provided. When the device comprises two masks as shown, the operator must act on each of the tabs each moving a mask to activate the device. In the example shown in FIGS. 6 to 10, the first information carrier 3 is mounted irreversibly movable from an inactive position in which the first information carrier 3 partially projects from the base and its illegible barcode 4 in its entirety from outside the base 2 to a so-called active position in which the bar code 4 of the first information carrier 3 is readable in its entirety from outside the base. The masking means 15 are formed by the part of the cover housing of the first information carrier 3 in said inactive position of the first information carrier 3 and the drive means 16 for relative displacement of the masking means 15 and at least one of the information carriers 3 is formed by the part of the first information carrier 3 projecting from the housing in the inactive position of said first information carrier. This projecting portion forms a body 161 for manually actuating the first information support 3 from its inactive position to its active position. The user thus ensures, by pressing on the means 16 for moving the masking means 15, the sliding displacement of the first information carrier 3 in the direction of retraction into said housing formed by the base up to at a position in which the bar code of the first information support 3 is readable through the viewing window 10 of said housing constituting the base 2. In the example shown in Figures 1 to 5, the stop 17 stop here is simply formed by a projecting portion of the constituent plate of the mask. This abutment stop 17 bears against a stud 51 carried by one of the faces of the plate constituting the additional information support 5 in the active position of said stop 17. The driving tab in movement of the mask simultaneously drives the drive in displacement of the abutment stop 17 carried by the plate constituting the mask. This drive in displacement of the abutment 17 from its active position to its inactive position releases the support between abutment and stud, so that the additional information support 5 is retained only by the abutment 13 retaining formed by the component. In the example shown in Figures 6 to 10, the abutment stop 17 is formed by a projecting portion of one of the faces of the plate forming the first support 3 information. In a manner similar to that described above, this abutment stop 17 bears against a stud 51 carried by one of the faces of the plate constituting the additional information support 5 in the active position of said abutment. 17 stop. The displacement drive of the first information carrier 3 during the activation of the device 1 simultaneously drives the driving movement of the abutment stop 17 made in one piece with the first support 3 information. This drive in displacement of the abutment 17 from its active position to its inactive position releases the support between abutment and stud, so that the additional information support 5 is retained only by the abutment 13 retaining formed by the component.

In the example shown in FIGS. 1 to 5, the pusher carrier support plate 20 of the arming or resetting means 18 is common to the constituent plate of the mask and carries the abutment stop 17 so as to form a single and same room. In other words, the pusher carrier support plate 20 of the means 18 for arming or resetting a component 7 additionally carries the one or one of the masks 151 of the activation means 15 and the stop 17 of stopping the additional information medium associated with said component 7. This results in a simplification of the assembly. In the same way, the tongue forming the drive means for moving the arming or resetting means 18 is common to the drive tab in movement of the mask and the stopper. Thus, by actuation of this tongue, it is possible to cause a simultaneous movement of the active part of the mask, the abutment stop 17, and possibly the component 7, to bring it back if necessary to its initial position. It should be noted that this activation phase must be carried out after storage of the product under temperature conditions in accordance with the temperature to be controlled in order to avoid, as soon as the device is activated, a deformation of the component which could no longer be corrected. In the example shown in FIGS. 6 to 10, by sliding displacement of the first information support 3 for the passage of the device 1 from the inactive state to the active state, it is possible to cause a simultaneous movement of the 10 stopping stop 17, and possibly component 7, to bring it back if necessary to its initial position. It should be noted that this activation phase must be performed after storage of the product under temperature conditions in accordance with the temperature to be controlled in order to avoid, as soon as the device is activated, a deformation of the component which could no longer be corrected. Unlike the embodiment shown in FIGS. 1 to 5, in the embodiment of FIGS. 6 to 10, the only displacement of the first information support 3 with a view to activating the device 1 generates the arming of the two components 7 and unlocking the two additional information carriers 20. The casing may finally be equipped with a peelable adhesive strip 22 for adhesively fixing the device to the product whose temperature must be controlled.
