Description

Closure with odorant

The invention relates to an operable to open a container closure means, comprising at least one actuating portion, on which a user engages the closure means for performing an opening operation and a standing operatively connected to the actuating portion closure portion which closes the container and in which the container during the opening process is opened, wherein the closure means is associated with a fragrance for generating a predetermined fragrance, with which the activation of the release of the fragrance in response to the execution of the opening operation for opening the container is carried out and which comprises a fragrance reservoir, which the fragrance on takes, wherein the reservoir has a breakable during the implementation of the opening process Reservoirwandung. The invention further relates to a container provided with such a closure means and a method for opening a container.

Usually, especially in the food sector, products in protective packaging are packaged in such a way that they are not visible or detectable with another of the human senses. In this respect, modern packaging also has the task of giving consumers, or at least before consumption, consumers To convey the advantages of the packaged product. It is also advantageous to confirm the consumer over the packaging already made a purchase. In this regard, the packaging is a marketing tool that ideally addresses one or more of the human senses that can not be directly addressed by the packaged product.

One type of closure means is disclosed, for example, in European Patent EP 1 056 660 B1 in the form of a container closure molded from a plastic which is impregnated with a flavoring agent, i. with an agent that affects both the sense of taste and the sense of smell. It is proposed that the flavor or fragrance is preferably that of a consumable product such as fruit, sweets or drinks. The impregnation of the closure means with the fragrance causes the air surrounding the exterior of the closure member to be impregnated with said "fragrance" and to that extent produce the desired effect.

A drawback of such a closure is that it continuously delivers odorant to the environment, such that in a supermarket, for example, there is a risk of "odor overkill" due to the presence of a plurality of containers with such closure means, which may comprise a wide variety of fragrances. Although it may be provided in such conventional closure means in such conventional closure means by a special covering device, such as an additional lid for the closure means, the release of the fragrance into the environment at least to reduce.Here, however, an additional part of the closure means is necessary, further this is the artistic Possibilities for the closure means reduced.

A generic closure means is for example in published patent application DE 100 64 572 A1, which relates to a can lid having in its lid mirror a tongue for forming a pouring opening along a score line. The lid mirror has on its side facing the interior of the can side a separate, formed by walls space for receiving, for example, a fragrance, wherein the opening of the can, the inwardly moving part of the tongue exerts a force on the wall through which the room a Opening so that the fragrance can escape during the opening process. Although such a design avoids the above-described "odor overkill", it is disadvantageous that the fragrance may possibly come into contact with the food stored in the container during the opening process, which is often undesirable.

The invention has for its object to at least partially remedy the disadvantages described in a conventional, operable to open a container closure means, which is associated with a fragrance. This is achieved in a surprisingly simple manner on the device side already by a closure means operable to open a container with the features of claim 1. The closure means according to the invention is characterized in that the fragrance is attached to the actuating section.

The invention is based on the idea of providing a closure means in which the fragrance is attached to the actuation section so that as a rule it can be avoided to provide the fragrance in the region of the closure section, whereby ultimately contamination of the food with the fragrance can be prevented. Preferably, in the region of the closure portion, ie the portion of the closure means which closes the container and in which the container is opened during the opening process, no fragrance is provided. Instead, the fragrance is preferred wise alone on the operating portion, it should be noted that this operating portion has an area which is touched by the user in the operation, but depending on the embodiment may also include one or more areas that are not touched during the operation usually.

It should be noted that the term "fragrance ^λX may indicate a carrier which carries the actual perfume or fragrance agent, may also include other additives. However, it is also possible that the fragrance alone comprises the actual fragrance causing the fragrance, or a fragrance reacting with, for example, another fragrance reactant to form an odorant. Such fragrance substances, carrier materials or additives or fragrance ingredients of the fragrance-emitting fragrance or odor substance are well known to the person skilled in the art, which is why it need not be discussed in more detail below.

According to the invention, the means for timely releasable release of the fragrance for activating the release of the fragrance in response to the implementation of the process for opening the container is formed. By this design measure it is achieved that the fragrance is dispensed only when the closure means is actually operated, ie the container is opened. The invention achieves this by a coupling of the actuating portion, the closure portion or another portion of the container with a means for releasing the fragrance, which is addressed or activated to release the fragrance only in the implementation of the opening process. For example, a mechanical operative connection between the actuating portion for opening the container and the means for releasing the fragrance, thereby ensuring that only with or during the opening of the container, the means for releasing the fragrance is activated, so that the fragrance delivered to the environment becomes. According to the invention, the means for releasing the fragrance comprises at least one fragrance reservoir, which receives the fragrance, wherein the reservoir has a breakable during the performance of the opening operation Reservoirwandung. It is advantageous if the reservoir has fragrance-tight reservoir walls, so that no odorant is released into the ambient air of the container equipped with the closure means according to the invention before the reservoir wall breaks open.

Depending on the embodiment, the reservoir wall can in particular be part of the closure section, part of the bed section, part of another container section and / or comprise a coating, such as a lacquer, a film or a paper on the fragrance itself. In the latter embodiment, the fragrance is encapsulated insofar as breaking the capsule wall, the fragrance can diffuse into the ambient air. In particular, it may be expedient if a portion of the reservoir wall is formed by a fragrance-tight coating of the fragrance. In this case, the coated or encapsulated fragrance agent may constitute an outer interface of the closure means. If, during the opening process to open the container, this interface is broken up, the fragrance can escape.

In principle, it may be expedient if the means for releasing the fragrance can be activated by an application or generation means for applying or generating an activation energy. This activation energy may be, for example, a mechanical energy, for example by generating a movement against a frictional force, but also by generating a predetermined temperature, a predetermined humidity and / or generating an electromagnetic radiation, such as IR / UV or radiation in the visible area are provided. In addition, the activation of energy to increase the surface of the fragrance and / or to evaporate the fragrance provided to give off fragrance. The invention is not limited to configurations in which the release of the fragrance is controlled solely on the timing of the opening process. However, the design of the closure means according to the invention is such that the fragrance is released at the latest at the time of the opening process.

The arrangement of the fragrance on the closure means can be implemented in various places, in certain embodiments it is ensured that fragrance can escape into the air environment of the closure means or the container during the opening process, so that the fragrance can be perceived by a consumer when opening the container. For example, it may be provided to attach the fragrance to a food can or preserve such as a soda can on a surface of an actuating portion such as a tear tab of a container or a metallic tab generally referred to as a "tap." For example, such tab may be coated with an encapsulated fragrance. lacquered, glued or coated, the encapsulation breaking open when the actuating section is grasped during the opening process and a force is applied to open the container, and it can be particularly advantageous if such an actuating tab is designed as a lever for breaking a lid mirror. With this design, it can be made more difficult for a fragrance attached to the operating section to undesirably come into contact with the food product stored in the container.

In the case of an encapsulation of the fragrance, preference is given to microcapsules having a size of about 4 to 40 μm in diameter, preferably of a size of 5 to 10 μm in diameter. applies. The capsule material used is in particular melamine resin, crosslinked aminoplast or melamine-formaldehyde resin. Further, for example, acrylate resin or gelatin may also be provided which offer the additional advantage of not releasing formaldehyde.

Such a microencapsulated perfume may then be incorporated into a carrier such as an ink, varnish, or adhesive for application to the container or actuatable closure means. In this case, a volume fraction of 5-35%, particularly advantageously 20% of microcapsules to the dried mixture of paint / ink or ink, etc., and the microcapsules has been found to be particularly advantageous. The mixture of the carrier, such as ink or varnish, and the microcapsules is then applied, for example by means of a printing process, such as a pad printing, a jet printing process or a spraying process, in particular onto the actuating section. When using a spray or ink jet printing process, the process parameters or product parameters of the microcapsules are adjusted so that the microcapsules remain intact during the application process. After application of the mixture, it is dried, for example by infrared, laser or UV radiation.

In general, the fragrance may be attached to the container as well as to the container body. It is also possible that the fragrance is part of a coating, a paint, a film or a paper, etc. Moreover, it is possible within the scope of the invention for a coating, a lacquer, a film or a paper to be part of a reservoir wall which encapsulates the fragrance and which is broken up mechanically, chemically, photoelectrically or photochemically for dispensing the fragrance.

In a further expedient embodiment, the closure means may comprise a screw cap, which, for example a closure body having an internal thread, wherein the actuating portion is provided by the outer cylindrical surface of the closure body. In this embodiment, an encapsulated fragrance and / or a fragrance reservoir can expediently be arranged in the region of the outer cylinder jacket surface of the closure body, so that the fragrance can escape upon actuation of the closure by breaking open the encapsulation or the reservoir.

In addition, it may be expedient if the described screw cap has a guarantee strip which at least in sections comprises a breakable reservoir wall of the fragrance reservoir.

Conveniently, the closure portion of the closure means may comprise a part of the container wall and at least partially have a line of weakness at which the container wall breaks open during the opening process. Such a closure means is expedient, in particular in the case of a cardboard or plastic-backed flap, moreover also in the case of a container wall made of metal, for example in the case of a beverage can, or even in the case of a metallized film packaging.

The weakening line expediently extends over a wall section of the fragrance reservoir so that the fragrance reservoir is broken at the same time as the container is opened.

Advantageously, the actuating portion may be formed as an actuating tab which transmits the actuating force to the closure portion for breaking the container in the region of the closure portion.

Conveniently, the actuating portion comprises a portion of the Duftmittelreservoirwandung, which breaks open applying an actuating force by the user's attacking the operating portion. In general, it can be expedient for the actuating section to comprise a section of the reservoir wall which breaks open by engaging the actuating section and / or by actuating the closure means to open the container while applying an activation energy. In this case, a respective generating means for generating an activation energy as described above may be included.

Furthermore, it may be expedient for the closure section to comprise a section of the reservoir wall which breaks open by engaging the actuating section and / or by actuating the closure means to open the container while applying an activation energy. Again, the activation energy can be generated in a variety of ways as indicated above.

The closure means according to the invention is basically not limited to the fact that the fragrance is attached to the closure means, that is to say on the closure section or on the actuating section. Instead, the fragrance in the container, which includes a container body and the closure means, may also be attached to the container body. It may be expedient if the container body comprises a portion of the reservoir wall, which breaks open by applying an activation energy by attacking the user on the container to open the container. Again, the activation energy can be generated in a variety of ways, for example as indicated above. In this respect, the invention also includes containers in which the fragrance is attached to the container body, the user grips not only this, but also the container when operating the operating section, for example with the other hand, so that by engaging the user on the container body the necessary activation energy causes and releases fragrance. In addition, it can also be provided to attach fragrance to the container body and the closure means, so that at different locations simultaneously or temporally spaced scent is delivered to the container during the opening process.

In addition, it may also be expedient if the closure means, in particular the actuating portion, in the region of its surface comprises a multiplicity of encapsulated micro-fragrance reservoirs which break open when the actuating force is applied so that the fragrance can escape to the outside.

Furthermore, it may be expedient for the closure means to be designed in such a way that an actuating force for opening the container can be transferred to the closure section via a section of the reservoir wall and the reservoir wall is designed such that it breaks open when a predetermined actuating force occurs. This embodiment is suitable, for example, for use with a beverage can or a can.

In addition, it may be expedient if the actuating tab is designed as a lever which presses during the opening of the container with a lever arm on a portion of the Duftmit- telreservoirwandung to break them.

On the device side, the invention further relates to a food container with an inventively designed operable closure means for opening the container. Such a food container can be designed, for example, for bottling beverages such as milk or fruit juices, but also other products such as compote, yoghurt, etc., wherein the respectively used fragrance, which is assigned to the closure means or generally the container, selected with respect to the product is. In a particularly expedient embodiment it can also be envisaged to use a flavoring agent as fragrance which acts not only as a fragrance but also as a flavoring agent at the same time. For this purpose, the flavoring agent is placed in such a portion of the closure means in which it comes into contact with the product and / or with the mouth of the consumer when removed from the container, so that the flavoring agent can also unfold its effect on the taste side. In such cases, in which a flavoring agent is assigned to the closure means for opening the container, the flavoring agent is arranged in the region of the closure portion in which an opening in the container is released or generated during the opening process in such a way that the opening operation simultaneously Flavoring agent is released and / or released. For this purpose, the flavoring agent may be arranged as described above for the fragrance in said region of the closure portion, but also generally on the container.

The object on which the present invention is based is achieved on the method side by a method for opening a container with an actuatable closure means, which has at least one actuating section, on which a user engages the closure means for performing an opening operation, and one which is operatively connected to the actuating section Container closing closure portion, wherein an opening of the container in the closure portion is released or generated by actuation of the closure means and wherein through the container, in particular by the closure means a fragrance is discharged, the timing of the fragrance delivery is controlled selectively, such that the fragrance delivery during the execution of the opening process is activated. The method according to the invention is characterized in that the fragrance is applied to the actuating section. Conveniently, the fragrance is applied in a region of the operating portion, in which the User touches or touches the operating portion for performing the opening operation.

It may be expedient if the fragrance delivery is activated by setting ambient conditions for the container, such as temperature, humidity and / or power flux density of electromagnetic radiation in the visible, UV or IR range. The adjustment of these environmental conditions may be coupled to the performance of the opening process, i. the opening process is designed so that automatically also at least one of the specified environmental conditions of the container is changed, so that the fragrance delivery is activated. For example, a reservoir for the fragrance can be broken by the actuation of the closure means, so that it is exposed to a humidity or electromagnetic radiation, which activates the fragrance itself for fragrance delivery.

It should be noted that the term "opening operation" used above in relation to the closure means and the method for opening the container comprises all the time phases which are directly related to the opening operation of the container In this respect, this opening operation does not include the removal of any cover of the closure device provided, if, after removal of the cover, the container itself does not yet open and the product stored in the container is not yet accessible.

In a particularly advantageous embodiment, it is possible to provide a photochemically activatable fragrance that is arranged in a light-tight manner on the closure means, wherein a light supply to the fragrance is made possible when the closure means are actuated to carry out the opening process. It is sufficient if the photochemically activated fragrance encapsulated or disposed in a reservoir on the closure means, wherein this reservoir is broken during the opening process or the encapsulation of the fragrance is destroyed.

In a further embodiment, it may be expedient if, during the actuation of the closure means, a wet-chemical reaction of the fragrance is activated such that fragrance is released. This method is particularly useful when the fragrance used is activated by a reaction with a body secretion such as sweat. In addition, however, it can also be provided that the wet-chemical reaction between the fragrance and the product stored in the container is produced, wherein a contact of both reactants takes place during the removal of the product from the container.

It can be particularly expedient if a plurality of fragrance components reacting with one another to produce the predetermined fragrance are arranged as reactants separated from one another on the closure means, whereby contact of the fragrance components with one another is made possible when the closure means are operated to perform the opening operation. Since in this case, both reactants can be matched exactly, the generated fragrance can be precisely determined. It is understood that in this case, the fragrance components, for example, together can perform a wet-chemical reaction to produce said fragrance.

Appropriately, upon actuation of the closure means, a force can be exerted on the fragrance, such that, for example, the encapsulation of a fragrance is broken or the surface area is greatly increased by the volume of the fragrance, so that the fragrance delivery is activated or enhanced by the enlarged surface.

In addition, a means may be provided by the upon actuation of the closure means, the fragrance is vaporized, atomized or atomized, so that the surface of the fragrance is greatly increased and thus the fragrance delivery is activated or substantially increased by the enlarged surface.

It is particularly expedient if a reservoir comprising a fragrance is arranged on the closure means, which is broken open upon actuation of the closure means, so that the fragrance can escape. In this case, the application of an activation energy can be connected to the actuation of the closure means to activate the fragrance delivery.

Furthermore, it may be particularly useful if the fragrance is attached to the operating portion and the fragrance is released by the gripping of the operating portion by the user. The release of the fragrance may, for example, by a wet-chemical reaction of the fragrance with sweat on the user's hands or by the bursting of encapsulations of a fragrance, which is attached to the surface of the operating portion. This method is suitable for example in those cases in which the actuating portion is formed by an outer surface of a screw cap, a tab of a tear strip on a cardboard / plastic / or metal packaging, a composite packaging or by a riveted metal tab of a can container. Insofar as the actuating portion, but not the closure portion of the closure means, comprises fragrance attached thereto, for example in the form of a reservoir such as a microencapsulated fragrance, it is generally avoided that the fragrance comes into contact with the product stored in the food container.

In further embodiments, it can also be provided that the fragrance is applied to the closure section, in which the container is opened during the opening process. In order to to prevent fragrance from being dispensed prior to performing the opening operation, the fragrance may be encapsulated or disposed in a reservoir. The arrangement can be arranged both on the inner and on the outer surface of the closure section, but also within the wall of the closure section. This arrangement may be such that the reservoir can be broken in the opening process and fragrance can be dispensed.

The invention will be explained in the following by describing a plurality of embodiments and further features according to the invention with reference to the accompanying drawings, in which:

FIG. 1a shows a first embodiment of a container with a quasi-shaped design and closure means designed according to the invention in the closed position,

FIG. 1 b shows the container shown in FIG. 1 a after actuation of the closure means;

FIG. 2 a shows a second embodiment of a container in the form of a bottle with a screw cap as closure means, which has a guarantee strip,

FIG. 2b shows the screw closure shown in FIG. 2a after it has been actuated,

Figure 3a shows a detail of a third embodiment of a container in the form of a beverage can with a "stay-on-tab" closure system and

FIG. 3b shows the closure system of a beverage can shown in FIG. 3a in an open position

shows. A container designed according to the invention may in principle be formed from or comprise a multiplicity of materials, for example plastic, paper / cardboard, metal or a composite material. The exemplary container shown in FIG. 1 a is a cuboidal carton 10 which has an operable closure means 20 on a container wall 11. This comprises a tab-shaped closure portion 22, which merges into an actuating tab 21, on which a consumer can attack. The closure portion 22 is part of the container wall 11 and with respect to the rest of the wall by means of a line of weakness 23, which may be formed under certain circumstances as a perforation, delimited.

In a non-illustrated form of the container this can also be designed as a bag. Depending on the embodiment, the container according to the invention can be dimensionally stable or not dimensionally stable.

In the region of the closure section, below the outer surface of the wall 11 or the closure section 22, a fragrance reservoir 30 is arranged in the embodiment according to the figures la / b, in which a fragrance is placed airtight or fragrance-tight and dashed lines in the figures. The reservoir can for example be incorporated directly into the cardboard wall, so that the reservoir wall also comprises cardboard material. In other embodiments, the reservoir may also include a thin plastic film in which the fragrance is embedded. It should also be pointed out that, depending on the embodiment, the fragrance reservoir can be arranged inside the container wall or on its outside or inside. In all embodiments, the reservoir is placed so that it ruptures or breaks during actuation of the closure means, so that the fragrance can escape.

In the example shown in FIG Actuation tab 21 on its surface to a coating 31 or paint on or comprises a further fragrance, but the air and thus fragrance-tight encapsulated, but the encapsulation is breakable by the application of an external force. In this respect, the encapsulation of the fragrance is canceled when the user to actuate the closure means 22 engages the actuating tab 21 to tear the locking tab 22.

The conditions with partially opened locking tab are shown in Figure Ib. By actuation of the closure means an opening 12 has formed in the container, the Duftmittelreservoir 30 is broken, so that fragrance can escape. At the same time, the encapsulation of the fragrance in the coating 31 was released by touching the actuating tab 21, so that fragrance can also escape at this point for scenting the ambient air. In the context of the invention can of course also be provided to install the fragrance only in the area of the operating section.

In the exemplary embodiment illustrated in FIGS. 2a, b, the container is a bottle 40, in particular a plastic bottle, which has an external thread, not visible in the drawings, in the region of its neck 41, onto which the closure means in the form of a Screw cap 50 can be screwed on. The actuating portion is provided here by the cylindrical wall 51 of the screw 50. At the bottle-side end of the screw cap 50, this has a guarantee strip 54, wherein a perforation 53 is provided, which deposits the guarantee strip 54 from the rest of the closure 50.

Attached to the outer surface of the actuating portion 51 is a scent agent in the form of a scent reactant 62 which reacts with the moisture in the hand sweat of an actuator of the closure to deliver a scent. In the illustrated Embodiment of the scent reactant 62 is only partially applied to the cylinder wall of the screw cap, it is of course readily possible to provide the application of the fragrance over the entire surface of the screw cap.

Furthermore, at least one fragrance reservoir 60 is provided which extends in the region of the guarantee strip 54 as well as via the perforation line 53 into the section of the remaining closure 50. For example, in one embodiment, the fragrance reservoir may include a closed plastic sheath that receives the fragrance. This envelope may, for example, be mounted on the inner side facing the bottleneck 41 or on the outside of the closure and extend beyond the perforation line starting from the guarantee band. Figure 2b shows the situation after the operation of the screw cap, whereby the webs 55 of the perforation 53 are broken and beyond the fragrance reservoir 60, so that the fragrance contained therein can escape.

Figures 3a, b show a further embodiment of a container according to the invention, which is designed here as a beverage can, which is shown in the figures only in section. The beverage can 70 has on one of its end faces a closure mirror 71 on which by means of a rivet 82, an actuating tab 81 is attached. Partly in overlap with the actuating tab 81, a closure portion 83 is arranged, which is fixed in the mirror 71 by a line of weakness 84. Depending on the embodiment, either on the outside or on the inside of the mirror 71, an optional perfume reservoir 90 may be arranged and secured so as to partially extend into and also be secured to the closure portion 83. Furthermore, the actuating tab 81 in the area in which an operating person attacks the same, a coating 91 which a encapsulated fragrance. As the person skilled in the art realizes, such an embodiment is generally suitable for a metallic food container, in so far also a tin can having on one of its front sides a closure mirror on which, for example by means of a rivet, an actuating tab is attached, on which the fragrance in the area is touched by the user to perform the opening operation. Also in this embodiment, the actuating tab may be partially arranged in register with a closure portion which is defined in the mirror by a line of weakness. By virtue of the fact that the actuating tab is moved upwards away from the closure mirror during the opening process, see FIG. 3b, it can be ensured that any product which foams out of the closure portion does not come into contact with the upper portion of the actuation tab 81 to which the coating 91 is attached is, and at which the operator engages the actuating tab 81 for the actuating operation. In this described embodiment, the fragrance is released at the latest when opening the container. However, it is quite possible to release the fragrance sooner by the user alone touching the operating tab without performing an operation to open the container.

Depending on the embodiment, the application of the fragrance to the actuating section, here on the actuating tab, can take place, for example, after the filling and closing of the food container, but also after or during the lid production, i. before bottling the product.

Upon actuation of the closure means 80, the person grasps the actuation tab 81 in the region of the coating 91 and moves the tab from its horizontal rest position, see FIG. 3a, into a substantially vertical position, see FIG. 3b. By the movement, the actuating tab 81 is supported on the closure portion 83 and breaks them out of the mirror 71st in the area of the weakening line 84 out and into the container inside. By applying the actuating force in the region of the coating 91, in turn, the encapsulation of the fragrance is broken, so that the odorant can escape. In addition, the optional fragrance reservoir 90 breaks, so that fragrance can escape here as well.
