The invention further relates to a container (14) for a liquid with limited shelf life, comprising a package (2) for receiving the liquid and a closure (1) for closing the package (2). According to the invention, it is provided that on the outside facing surface of the closure (1) with at least one number (4) and marked for the purpose of displaying the day of the onset of the package (2) individually manually markable fields (3) are arranged. The panels allow for marking by scribing and / or scoring, by thermally and / or pressure-sensitively induced color change, or by rubbing, peeling, and / or tearing off an outer layer. Such an indication can be used to record the day of the packaging breakthrough and to judge at any later time whether the liquid, for example a juice drink, is still within the period of the specified minimum shelf life after the packaging (2) has been opened for the first time. The container (14) according to the invention has such a closure (2) and / or on the outer surface (15) of the package (2) corresponding individually manually markable fields (16) for displaying the day of the Verpackungsungsanbruchs.

Description

The invention relates to closures for a packaging for a liquid with limited shelf life, comprising a inwardly in the closed state of the closure inwardly facing surface and in the closed state of the closure outwardly facing surface. The invention further relates to a container for a liquid with limited shelf life, comprising a package for holding the liquid with limited shelf life, the package having at least one liquid-side inner surface and at least one ambient-side outer surface, and at least one closure for closing the packaging.

Many liquids for certain uses have only a limited shelf life. Based on their production, they are assigned a period of time that is relevant to the typical time scales of human life sequences, production processes and / or market cycles, within which they can be safely consumed or used or used with undiminished effectiveness. This applies in particular to drinks intended for consumption, such as juice or milk drinks, in the food sector, liquids that can be used for cosmetic and personal care purposes, such as perfumes or body lotions, in the cosmetics sector and liquid medicines, such as cough syrup and eye drops, in the health sector. Voluntarily or by legal obligation, the manufacturers usually mark such products in the form of a calendar date on their packaging by specifying a best before date, an expiration date, a consumption date or a corresponding consumption or consumption recommendation. All these dates - which are summarized below under the generic term "best before date" or "shelf life" - have in common that they apply to the packaged product, as long as the packaging has not been opened and proper storage takes place. As a rule, the shelf life of liquids filled in packaging is considerably shortened even if storage continues to be appropriate due to the onset of packaging, ie the first opening by the user.

It should be noted that in the present application by the term "packaging" always the product directly containing primary packaging and not secondary packaging such as packaging or collective packaging are called. Examples of beverage packaging are glass or plastic bottles, but in particular also cardboard packaging (for example, for juices and milk), as quasi genus known from a brand for beverage cartons in the usual language under the term 'Tetra Pak'. For the purposes of sealing the packaging after filling the liquid (often at the manufacturer), later opening the packaging and pouring the liquid (often at the consumer) and - especially in the case of products that are not intended for immediate use or immediate consumption - reclosure are for liquid packaging closure devices, so closures such as. Rotary or screw caps provided. Notwithstanding that such device elements for closing the package are closely connected to the package at least in the closed state, in the present application the term "packaging" does not also include a closure associated therewith. For the assembled device, which consists at least of packaging and closure, the term 'container' is used.

The user or consumer is specified by the manufacturer on packaging or package inserts or by information from consumer organizations or similar. Make or know from personal experience - or it is researchable for him - how the shelf life of the liquid after the first opening (by opening the shutter), so the opening of the packaging, shortened. However, since there is no pre-determined start date, unlike the best before date, this endurance date can only be given as the period beginning on the day that the package breaks. The lasting knowledge of this day is therefore of central importance; if it is forgotten, the user has to resort to partly unsafe indicators (smell or color of the liquid, etc.) or to carry out partly risky taste or use tests, or premature disposal of the product into the waste, which is particularly problematic in the food industry is.

Known everyday techniques, the day of the onset of packaging with a liquid that has only limited or shortened durability after the first opening, have a number of disadvantages. Manual labeling of the container with the onset date (or the adjusted expiration date calculated therefrom) may not be clearly legible due to the handwriting for each of the user community (family, restaurant personnel, etc.). Furthermore, the lettering is typically exposed to moisture (dripping beverage pouring, condensation due to cooling, sweat on the hand of the user, etc.), which can fade the lettering in conventional pens or completely detach. If, however, a permanent marker used for labeling, this is just in the food sector due to odor as unappetizing or felt unhygienic. The same applies to the sticking of appropriately labeled adhesive labels on the packaging, which can also easily fall off. Keeping a labeled note sheet separate from the packaging, such as in another place in the kitchen or bathroom, not only carries the risk of accidental loss of this note, but - in pragmatic little detailed notes - even in terms of assignment a confusion between several opened packaging , All mentioned and similar procedures are also poorly used in situations in which the user is 'on the go', ie in transport, in sports, etc. and can use only little time and concentration on this process or wants.

In particular of fast food chains it is known that in beverage cups, which are handed to the customer to distinguish different cup contents (for example, a soft drink of its light variant) is pressed at several cups by the service force a correspondingly provided in the lid profiling. However, to transfer this labeling method or device to sticking to the day of dairy beverage packaging would have a number of disadvantages. Not only did the increase in pressure load until insertion or squeezing led to the risk of user leakage. Also, the provision of such substantial profile elevations or changes means creation of regions of the package and / or closure associated with material weakening (instabilities, break points, thinning of material, etc.) and thus either causing the risk of leakage on the product's transport paths or make it necessary to provide countermeasures with high economic effort in packaging, which are to minimize this risk, such as double-walled manufacturing. Furthermore, in the case of packaging and / or closures made of hard material (glass, hard plastic), a correspondingly compressible element would have to be placed, which would then be disadvantageous (especially for transport and storage) beyond the actual packaging profile. On the other hand, it is advantageous with the mentioned method that a marking on the lid, i. on the closure element of the container, takes place, since here in most cases a particularly well visible region is present - beneficial both for the memory, such a marking at all and also almost simultaneously to make the starting process, as well as for the subsequent compliance with this mark. In some other cases (as partially realized in the above-mentioned everyday techniques), it is advantageous to stick to the onset day in the area of packaging, for example if the closure is mostly removed at break-in (which, however, is rare in the aspect of durability, since reclosability is preferable here) or, in particular, where the closure does not have sufficient space for a suitable marking or an interchanging of closures of various container specimens must be obtained.

The publication DE 10 2010 024 909 A1 discloses a container, in particular a fuel canister, on the outer surface of which a scale is provided for displaying various contents of the container. By adjusting a movable display element, for example a slide or a turntable, the current content of the container can be displayed by means of the scale. The comparatively complex device allows for alternate displays, but on the other hand, is susceptible to inadvertently displacing a made adjustment of the movable display element by accidental contact or other force effects.

In the publication GB 2 440 567 A discloses a container suitable for storage of food, in the lid of a device is provided in which by means of the manual adjustment of at least one pointer on a circular disk-shaped scale by the user information regarding the current contents of the container can be displayed. The display can be adapted to changing content, so it is reusable according to the container use. However, it thereby presents an economically disadvantageous complexity for once-only mass-produced items such as beverage cartons and is in danger of being inadvertently displaced by movement of the container or impacts.

In the publication US 2016/0 137 364 A1, an arrangement of markable fields is proposed for the lid element of a food container, with which the day of the week of filling food into the container by pressing one of the protruding fields by finger pressure of the user can be displayed. The comparatively complex device allows reuse of the display by a manual reset possibility of the indented fields to their original position.

From the document US 2012/0 153 031 A1 a cap for a medicine container is known, on which a circular bar code is provided which encodes information regarding the container and its contents. The information is read by the user, but no manual markings on the barcode fields are possible.

The object of the invention is therefore to provide closures for a packaging for a liquid with limited durability available, which allows a permanent, easy to recognize and easy to generate display of the actual onset day, without functionality or load capacity of the closure are thereby adversely reduced. It is also an object of the invention to provide a container for a liquid with limited shelf life, which allows a permanent, easy to recognize and easy to generate display of the actual onset day, without the functionality or capacity of the container are thereby adversely reduced.

The object of the invention is achieved by a closure for a packaging for a liquid with limited shelf life with the features of claim 1, of claim 2 and the features of claim 3 and by a container according to claim 7. Further advantageous embodiments are specified in the subclaims to claims 1, 2 and 3 and to claim 7.

According to the invention, therefore, it is provided on the one hand that are marked on the outwardly facing surface of the closure with at least one number and marked individually for the purpose of displaying the day of the onset of the package individually manually markable fields, each with at least one each Number of marked fields at least partially from the manual marking of the field by scribing and / or notching suitable paper material and / or plastic. The fields represent planar sub-elements of the surface of the closure which are perceptible to the external observer, e.g. by graphic border or the respective field framing profile lines. This is particularly advantageous even when the closure is in the closed, so the packaging occlusive state, since it is a in the closed state of the closure outwardly facing and therefore visible, so not - when used in combination with a package - to a surface on the liquid side to the interior of the packaging surface is. The fields are marked with numbers, for example by imprint or by profiling, and are suitable for displaying the day of the onset. Since it is an indication of the day in a month, the rule is therefore to provide 31 fields, marked with the numbers 1 to 31. In principle, however, a different coding of the calendar days by numbers (which also includes other numerals than those used in Central Europe and any numbers including significant symbols) as well as the consideration of non-Gregorian calendars are possible. The numbers used thus determine how many fields are to be provided at least. As a rule, closures in packaging for liquids of limited shelf life also serve to reclosure the packaging opening after it has been opened for the first time; The best arrangement of the fields depends on the geometry of the shutter and the visibility of the external observer. In the event, however, that parts of the closure are removed and not used for reclosing (but disposed of in waste) at the first opening, it will immediately follow for the skilled artisan that the purpose of indicating the durability indication fields will be that the closure will also be affixed to the packaging when used as intended must have remaining or re-attachable parts and the fields are not arranged on the irreversible parts of the closure.

The fields marked with the numbers for days each allow a manual marking by the user, usually at the beginning of the package. 'Manual' here means by hand ('by hand') or 'by hand' with a hand-held, non-automatic or non-powered or non-mechanical aid in the area of force of the human arm / hand Force expendable forces. Marking operations by means of a human fingernail, a fingertip or a knuckle, as well as by hand-made use of everyday objects, such as pens, coins, cutlery (including their grip ends), etc., are therefore typically considered. If that field is marked, which corresponds with its characteristic number to the current day of the month at which the package break is made, the starting point for the shelf life calculation of the liquid in the packaging, with which the closure is combined according to use, is recorded. which, as the subsequent specifications show, can be easily achieved, easily recognizable and permanently achieved. Since only the fields are used for this, there is no impairment of the functionality and material integrity or resilience of the closure. The user may presuppose the knowledge of the current day, the possibly necessary later reminder of the corresponding month as well as the knowledge of the basic shelf life (in days / weeks / months) of the liquid after the packaging has broken. Typical cases here are juices, which are to be consumed within a few days after the first opening of the packaging. In principle, the consumer is free to mark on opening on the fields by invoice and the day from which the liquid should no longer be consumed or used. Since different storage conditions (eg temporary omission of cooling) occur after first opening and durability However, it may be preferable to mark the date of the first strike as it could be risky if there were any unforeseen circumstances and any misinterpretation of the marked day could be risky.

In a solution according to the invention, it is provided that the fields, which are identified by at least one number as the basis for the durability indicator, can be marked in such a way that they can be marked by manual scribing or scoring. The panels consist, at least in part, of the extent to which a well recognizable marker can be placed, of a paper material and / or plastic that can be scratched and / or scored manually (as described above) , For example, the consumer can use one of his fingernails or a paper clip or similar. To take help and thus by a tangential scribing movement or perpendicular to the field acting compressive stress permanently at least one tapered or wedge-shaped incision, a notch, and / or the tightness not endangering depression in the form of a narrow column, a crack produce. For this purpose, a permanently deformable plastic under these loads or a paper coating that is porous or has perforations or other already created, local material weaknesses. In a very simple and durable way, the user can thus by a quick action, such as with your fingernail on the appropriate field to score, hold the date of arrival prominently on the closure. The field material may thereby allow to be customized by patterning at scoring (e.g., dashes, crosses and circles), e.g. to leave the information in a family household, who made the marking or the beginning of the packaging.

In a further inventive solution it is provided that in the fields marked with at least one number each field by manual pressure application or by the action of body heat on the fingers or the hand, a color change can be effected. The permanently adjusted color, including the change from "opaque" to "transparent", thus forms the desired marking of the appropriate, individual field, as - similar to notching or scratching - thus a highlighting of a field compared to the other fields is brought about , Even if the characteristic number of the field is no longer directly recognizable after such markings, the viewer is immediately clear from the comparison with the unmarked fields which field or which number is involved. It is therefore provided that the individual fields at least partially consist of a thermosensitive material or on the outer surface are at least partially coated with a thermosensitive material, wherein the thermosensitive substance in static and / or rubbing contact with skin areas of a human hand to mark the Field has appropriate color change; and / or it is envisaged that the individual fields at least partially consist of a pressure-sensitive substance or on the outer surface are at least partially coated with a pressure-sensitive material, wherein the pressure-sensitive substance has a color change suitable for marking the field under manual pressure loading. Again, the external surface characterization refers to a portion of the field surface which, at least in the closed state of the closure and insofar as it is not coated, can be seen by an external observer (external to the vessel), i. Environmentally located. Thermosensitive chemical substances and pressure-sensitive chemical substances, which can be brought under the conditions mentioned to an irreversible color change, are known in various technical fields. The average body heat on fingertips and knuckles, possibly reinforced by rubbing them with the field, leads to such color changes, for example, in thermo-lacquer-coated paper or plastic, for many types of thermal lacquer. Thermal paints, which do not tend to change temperatures even at even lower temperatures, are obviously particularly suitable. Suitable pressure-sensitive materials are carbonless paper in which substances are released under pressure which react with atmospheric oxygen or with one another (as colorants and color formers) in such a way that color changes, often in the form of darkening, appear.

In a further inventive solution it is provided that each of the fields marked with at least one number at least in parts of its outer surface a removable by manual rubbing and / or a manually peelable and / or a manually peelable, outer first layer and a mark of the Field has suitable, lying directly under the outer first layer second layer. If the visible outer surfaces and thus also the outer layers, which are referred to as 'first' from outside to inside, are of the same color, a marking of a field is permanently and easily recognizable when the first layer is at least partially removed and below a second layer is visible, which has a strikingly different color or color design. The user can carry out this marking easily and without further instructions, since a method familiar to him from decals, scratch-offs or tear-off sheets can be used here. At the same time, these cases provide examples of technical examples for the person skilled in the art, such as the fields in this variant according to the invention, in which a first, uppermost layer is manually removed (in the sense described above) by rubbing, peeling or tearing, are to be carried out in the production.

The closure according to the invention can be embodied in various known types of closure, for example as a screw cap, also referred to as a rotary closure, as a closure with a removable or pivotable closure cap or, for example, as one of the commercially available closures known from Tetra Paks and other beverage packaging, for example by a simple closure Tensile and / or twisting movement are open. A series of closures or closure types is characterized in that the closure has a pouring element with a pouring spout for pouring out the liquid from the packaging and a closure cap for closing the pouring element. For such closures, in one embodiment of the invention, it is provided that each of the fields marked with at least one number is arranged on the pouring element, or that each of the fields is arranged on the closure cap or that some of the fields on the pouring element and the remaining fields on the pouring element Cap are arranged. A typical basic form of the pouring element consists of a cylindrical tube protruding from the packaging when intended for combination with a packaging, onto which the closure cap can be slipped or screwed by means of a thread. Further, the tube is flared at one end and there, when used properly with the package, e.g. by gluing, connected. The user can remove the liquid from the packaging through the tube and the spout opening given thereby. In the case that the fields or at least some (ie at least one but not each) of the fields are arranged on the pouring element, these are arranged in a first variant of the closer in a region which is visible from the outside even in the closed state of the closure, For example, on the surface of a flange extended area. This has the advantage that the marked start day is always visible and therefore available as information. In the second variant, the fields are arranged in a region of the pouring element, which is not visible from the outside in the closed and especially in the reclosed state of the closure, for example. At a tube-like shaped part of the pouring in a section of a plugged Cap is hidden. In this case, the advantage is that the markable fields are protected from unwanted marks by random contact and further that the first mark can not actually be made before the first opening.

In a further embodiment of this embodiment, the closure cap is designed as a screw cap or as a pivotable, cap connected to the spout closure cap, wherein the closure cap has a substantially cylindrically shaped side surface and a substantially planar top surface. In this embodiment, it is further provided that each of the fields marked with at least one number is arranged on the top surface or that each of the fields is arranged on the side surface or some of the fields are arranged on the top surface and the remaining fields on the side surface. Under aspects such as, for example, the size of the closure, the typical storage of the container (upright or lying etc.) or even design considerations of product design, the durability indicator can be laterally and / or on the top surface of the cap, so the on the one-sided completion of the cylindrical shape of the side surface, be placed. It is essentially in its basic form, i. except for possible low profiling or a slight curvature, even, so that an arrangement of the area-like fields is possible without affecting their display function. In this regard, it is technically irrelevant whether the cap is screwed, articulated - for example, by a hinge joint - pivotable or completely removable and re-attachable. An array of fields is also substantially on the, i. except for negligible deviations such as small, the grip-increasing profile lines or contour lines between the fields, in its basic form after a type of cylinder jacket shaped side surface possible.

It is possible to carry out the closure cap as a screw closure cap or as a pivotable closure cap connected in an articulated manner to the pouring element, wherein the closure cap likewise has a substantially cylindrically shaped side surface and a substantially planar cover surface. In this case, however, there is the special case that the fields are arranged on the top surface of the closure cap. For the marking of the individual fields can be provided that on the top surface a rotatably mounted, manually parallel to the top surface in pointer positions of two groups of pointer positions rotatable pointer is arranged. The pointer can therefore be rotated by the user or in two possible types of positions with the fingers or by hand with a tool. In the case of a pointer position, the pointer points from a first group of pointer positions to an area of the cover area outside the fields marked with at least one number each. This may be a position on a not marked with a number, but similarly contoured field - as one of the manufacturer default starting position, in which no tag is displayed - act. Furthermore, the pointer points at a pointer position from a second group of pointer positions to one of the fields marked with at least one number each, wherein a pointer position is adjustable for each field, in which the pointer points to this field. With such a position can thus be set, usually from the neutral starting position coming, a day of packaging breakthrough. It should be noted that the term 'group' is neither based on nor correlated with a technical or a mathematical meaning, but only in summary refers to the two explained pointer setting modes. Advantages of the marking by such a pointer are the quick, particularly easy to perform adjustability and a good recognition of the pointer position. For a permanent preservation of the set pointer position - especially against the force of gravity, movements of the container or at least the cap and accidental touches of the pointer - can be generated either by stiffness of the bearing of the rotatably mounted pointer or by friction resistance of the pointer on the top surface caused stiffness become. Particularly suitable for this purpose is a separation of the fields by increasing the profile between the fields and a tightly positioned on the top surface, but suitably elastically bendable pointer, so that the pointer can be snapped into position on a field. The person skilled in the art will obviously arrange the fields along a circular arc in such a way that each field can be marked by the pointer end rotating on a circular arc, for example, as an arrowhead.

For certain liquids, a relatively long shelf life can be given even after the packaging has broken, for example in the medical or cosmetic field. Therefore, in a further embodiment of the closure according to the invention, in addition to the group of fields provided for displaying the day of the packaging break, individually manually markable fields and basically independent of their spatial arrangement and the method of their permanent marking, a second group of fields on the outside arranged facing surface of the closure. Although these are also planar sub-elements of the surface of the closure, but need not be identical or even congruent with each other compared to the fields of the first, associated with the daybreak mark group (as well as the fields of the first group with each other this is not necessary need to be). It is provided that the at least second group of markable fields consists of individually manually markable fields, which are each marked with characters that correlate to the day of the onset of the packaging to display the corresponding calendar week and / or the corresponding month and / or suitable year. Thus, at the same time or alternatively the day of the onset, the calendar week of the onset and / or the month of the onset and / or the year of the onset can be marked and thus permanently readable. For example, fields with the month names are provided as the characters characterizing the fields or with the numbers of the calendar weeks. For example, at the month of the first opening of the packaging and the sources of error in persons who have not made even the start and retrospect, if necessary, can only estimate what, for example, month it was, eliminated. Again, the user is free to set a calculated end date of the shelf life. For better differentiation, the individual field groups (for days, months, weeks or years) can be designed in different colors. In the special case, a corresponding hour display with a separate field group on the closure according to the invention can also be provided for cases of particularly rapid perishability.

According to the invention, it is further provided that the container for a liquid with limited shelf life is characterized in that the at least one closure for closing the package has the features of any one of claims 1 to 6, the container thus having a packaging and at least has a closure over a closure according to the invention as set forth above and specified in the cited embodiments, has. Alternatively or in combination thereto, it is further provided according to the invention that on the at least one outer surface of the package with at least one number marked and individually for the purpose of displaying the day of the onset of packaging manually markable fields are arranged, the features of individually manually markable Fields on the at least one outer surface of the packaging to the characteristics of the fields according to one of claims 1, 2 or 3 correspond. It is therefore envisaged that the fields for marking and displaying the first day of the container in this case are recognizably arranged on the packaging for the outer observer. In basically the same idea of the invention, the marking of the onset day is now on the outer surface of the package, but with the already explained for the closure of the invention conditions and devices for scribing and / or scoring, for thermosensitive and / or pressure-sensitive marking or rubbing, peeling and / or tearing removal of an outer field layer instead. The outer surface is insofar as the environment to characterize as by a generic packaging separation into an interior, which receives the liquid filled in the packaging, and an outer space surrounding the container takes place.

In an advantageous embodiment of the container according to the invention it is provided that individually marked on the outwardly facing surface of the closure and / or on the at least one outer surface of the packaging with at least one number and marked individually for the purpose of displaying the day of the onset of packaging Fields are arranged. It applies to all these fields that each of these fields, at least in parts of its outer surface a removable by manual rubbing and / or a manually peelable and / or a manually peelable, outer first layer and suitable as a marker of the field, directly below the outer Having first layer lying second layer. Furthermore, it is provided in this embodiment that in each of the at least one number marked fields on the second layer, a bar code and / or a QR code is arranged. The bar code and / or the QR code - a very widespread two-dimensional code - contain as coded data at least the tag displayed by the respective field and the type of fluid contained in the packaging.

If the first outer layer of the selected field is removed according to the purpose, the code is thus exposed to the outside and can be scanned or scanned in by a suitable reading device known per se. There are in this embodiment, a mobile application software - usually synonymously referred to as 'App' - and provided a database, wherein after reading the bar code and / or the QR code using a smartphone used as a reader, the encoded data from the mobile application software / App be decoded, stored, recalled and combined with information from the database. This information concerns at least the durability of the liquid of this kind after the packaging has been opened. By means of an app to be programmed in a known manner and an appraisable in a known manner database on the app after reading the code with the smartphone data reading access, the user or possibly multiple users on the display of the smartphone not only Management options (consumption or exhaustion plans, etc.) of the read-in for several liquid container core data (start day and liquid type) are provided, but also optionally further information, for example. Storage, consumption / consumption recommendations and information on the durability and durability exceeded of this liquid, to be displayed.

An advantage of this embodiment is in particular that not only by reading the day marker on the container by the viewer, but also by subsequent successful scanning the day of arrival can be determined, so that the day must not be subsequently entered by hand in the app, which is not comfortable and at least a source of error would be. In fact, the situation is entirely to be expected that the user at the moment of opening the pack does not have his smartphone at hand, e.g. during sports. In addition, it is also possible to provide in the bar or QR code information for identifying the individual container used. This may be useful, for example, in cases in which, for example, in catering establishments, the uniqueness of the daily mark has been lost by accidentally marking at least one additional field in a multiplicity of identical beverage containers, since the product is additionally reidentifiable in a rapid manner by renewed scanning, without having to access other labels or codes on the packaging in additional steps.

In the illustrated embodiment, the markable fields are 3 on the side surface 9 the cap 6 arranged, which, for example, space for a different kind, for example, with brand name specification moving design of the top surface 5 leaves.

At the in 5 schematically illustrated closure 1 is a pointer 10 present, with two different pointer positions simultaneously 11 this pointer 10 were included in the picture. When pointing up in the figure pointer position 11 points the pointer 10 to an area where there is no one with a number 4 marked field 3 located. This pointer position 11 can be used as the base, home or neutral position of the pointer 10 be designated, which should be preset in the rule when purchasing the product manufacturer. At first opening the packaging 2 the appropriate start day permanently by appropriate marking of the appropriate field 3 the user turns the pointer 10 manually in the corresponding pointer position 11 , In the picture shows the arrowhead of the pointer 10 on the day "10", so that it is possible to deduce a start day that bears the date "10.mm.yyyy" in the current or correctly remembered earlier month. For one in spite of possible movement of the lock 1 permanent adjustment of the pointer 10 in this pointer position 11 is a high rotational resistance for the pointer 10 and / or the possibility of detenting the pointer 10 in the fields 3 intended.

6 sketchy shows a section of the annular array area of the fields 3 as he is about in 1 is shown. Unlike the embodiment described in 2 are shown are in the embodiment of the closure according to the invention shown here 1 the fields 3 coated with a fabric 12 (or consist entirely of such a substance 12 ), which is pressure and / or thermosensitive. Right next to the field 3 , which is marked with the day "8", is a field 3 (- one concludes in the overall view obvious on day "9" -), the one to the marking of this field 3 suitable color change 13 having. Here was by pressure load and / or transmitted by body heat and temperature-increasing friction or touch operations of the pressure or thermosensitive chemical substance 12 manually to a change 13 its color (including a possible change from an optically opaque to a transparent state).

7 and 8th show a container according to the invention 14 for a liquid having a limited shelf life, for example a beverage container ("juice box" or the like) with fruit juice containing a cap 1 and as another component a packaging 2 having. In the illustrated embodiment are on the closure 1 no fields 3 arranged for permanent marking of the first day. Rather, to fulfill the same purpose, the permanent display of the first day of this container 14 , on the outside surface 15 the packaging 2 fields 16 which are marked with numbers corresponding to the days in a month and of which the appropriate field 16 can be marked on the day of arrival. Especially with small closures 1 is with fields 16 that kept comparatively large on the outside surface 15 be arranged, a better visibility of the marked fields 16 and their markings. According to the embodiment 7 became a marker 7 by scratches and / or notches in the field 16 made for the day "22".

In contrast to this, with otherwise the same design as in 7 in the embodiment according to 8th marking by manually rubbing, peeling or tearing off the outer first layer 17 of the relevant field 16 causes. This is exemplary and only for the representation within only one figure for the fields 16 the days "11" and "22" shown. On the thus exposed second layer 18 There are codes in this embodiment 19 . 20 in the tag "11" field 16, a bar code 19 and in the tag "22" field 16 a QR code 20 , In the codes 19 . 20 the information shall be at least the day of commencement of the field and the type of liquid contained in the container 14 according to manufacture, encrypted. Also, the individually given container 14 coded for simultaneous identification or re-identification. With a smartphone used as a reader (not shown), the respective code can be scanned. In this case, an app is provided, which uses a database with information on durability, risks in case of exceeding durability etc. in the given type of liquid and provides the user on the display of the smartphone. Since the app receives the day of the day of the day of the day on the code and does not have to resort to the calendar function of the phone, which only the current day of the scanning process is displayed, a possibly umständervorber only a few days later scanning the code can the first day in one step immediately read.

In 9 are over the fields 3 that - as above too 2 explained - are suitable for marking the first day, in addition also fields 21 arranged for the marking 7 - In the example shown by scratches and / or scoring - the onset month are suitable. The characters 22 with which these fields 21 are accordingly month names. It is advantageous to provide such fields 21 to display calendar week, month and / or year for liquids with long shelf life even after the first opening of the packaging 2 , Such additional fields 21 can, as well as the fields 2 for day marking, also on the outer surface 15 a packaging 2 to be ordered.
