Abstract

Tiskan temperaturni senzor v pametni embalaži (1) se izdela neposredno na tiskarskem stroju, kjer se le-ta natisne na prvi zgornji sloj notranjega dna (2) kartonske embalaže. Merilni sistem (3) je vložen v samo dno večslojne kartonske embalaže, neposredno pod prvim slojem kartona na katerem je natisnjen senzor. Povezana sta preko kontaktov (4). Tiskan senzor je zaščiten s temperaturno obstojnim laminirnim slojem (5), ki vključuje grafični, tiskan kazalnik ustreznega temperaturnega območja ali pa tiskan zaslon (6). Celoten sistem, tiskan temperaturni senzor v elektronskem merilnem sistemu, je lahko postavljen pod primarno embalažo (7) ali živilo, ki se hrani v sekundarni, prodajni embalaži (8), ali pa nastopa kot samostojni, neodvisni merilni sistem. V kolikor je vključen v dno sekundarne embalaže, se le to za lažjo uporabo loči od preostalega dela embalaže na osnovi pretrga perforiranega zgiba (9).The printed temperature sensor in the smart packaging (1) is produced directly on the printing machine, where it is printed on the first upper layer of the inner bottom (2) of the carton. The measuring system (3) is inserted into the bottom of the multi-layer cardboard packaging directly below the first layer of cardboard on which the sensor is printed. They are connected via contacts (4). The printed sensor is protected by a temperature-resistant laminating layer (5), which includes a graphic, printed indicator of the appropriate temperature range, or a printed screen (6). The entire system, a printed temperature sensor in the electronic measuring system, can be placed under the primary packaging (7) or a food stored in secondary, sales packaging (8), or acting as a stand alone, independent measuring system. Insofar as it is included in the bottom of the secondary packaging, it is separated from the rest of the packaging on the basis of a broken perforated joint (9) for ease of use.

Description

TISKAN TEMPERATURNI SENZOR V PAMETNI EMBALAŽIPRINTED TEMPERATURE SENSOR IN SMART PACKAGING

1. Področje tehnike na katerega se izum nanaša1. Field of the invention to which the invention relates

Predmet izuma je iz področja sekundarne embalaže za hranjenje različnih živil, za katere je zaželena kontrola temperature pred zaužitjem. Izum se nanaša na kartonsko embalažo iz večslojnega kartona z vključenim tiskanim temperaturnim senzoijem, ki omogoča končnemu uporabniku določitev ustrezne temperature pred zaužitjem živila. Bolj natančno gre za temperaturni, uporovni senzor, natisnjen s tehniko (konvencionalnega ali digitalnega) tiska, ki je postavljen na dnu pametne embalaže pod zaščitnim laminimim temperaturno obstojnim slojem. Inovacija je tiskan temperaturni senzor oziroma tipalo, merilni sistem pa ima konvencionalno zasnovo. Senzor sam ni vezan na vrsto merilnega sistema, tako se lahko merilni sistem nadgradi s sistemom za radiofrekvenčno komunikacijo. V skladu z mednarodno klasifikacijo patentov se izum klasificira v skupino B65D.The subject of the invention is in the field of secondary packaging for the storage of various foodstuffs for which temperature control prior to ingestion is desirable. The invention relates to cardboard packaging made of multi-ply cardboard with a printed temperature sensor, which enables the end user to determine the appropriate temperature before ingesting a food. More specifically, it is a temperature, resistive sensor printed with a (conventional or digital) printing technique, which is placed at the bottom of the smart packaging under a protective laminate temperature resistant layer. Innovation is a printed temperature sensor or sensor, and the measuring system has a conventional design. The sensor itself is not tied to the type of measurement system, so the measurement system can be upgraded with a radio frequency communication system. According to the International Patent Classification, the invention is classified in the B65D group.

2. Tehnični problem, ki ga rešuje izum2. A technical problem solved by the invention

Tehničnih problemov, kijih rešuje izum je več;There are more technical problems that are solved by the invention;

• integracija temperaturnega senzorja neposredno v proizvodni liniji, • senzor se dodatno zaščiti z laminacijo, • laminimi sloj je lahko potiskan, • nizki stroški izdelave zaradi možnosti masovnega tiska, • senzorje namenjen večkratni uporabi, zato je obremenitev okolja manjša.• Integration of the temperature sensor directly in the production line • The sensor is additionally protected by lamination • The laminate layer can be printed • Low cost of production due to the possibility of mass printing • Sensors are intended for multiple use, thus reducing the environmental burden.

Aplikacij je lahko toliko kot je različnih živil, za katere je zaželena kontrola temperature pred zaužitjem. Poleg vrste živila, ki narekuje uporabo določenega temperaturnega območja, uporabnost senzorja določa tudi vrsta in sestava merilnega sistema. Le-ta lahko kot kazalnik primernega temperaturnega območja uporablja niz LED diod ali pa tiskan zaslon (elektroluminiscentni - EL, termokromni - TK ali celo OLED). Temperatura ni prikazana natančno, ampak z določeno toleranco, ki ustreza določitvi ustreznega temperaturnega območja.There can be as many applications as there are various foods for which temperature control before ingestion is desirable. In addition to the type of food that dictates the use of a particular temperature range, the usefulness of the sensor is also determined by the type and composition of the measuring system. It can use a set of LEDs or a printed screen (electroluminescent - EL, thermochromic - TK or even OLED) as an indicator of a suitable temperature range. The temperature is not shown accurately, but with a certain tolerance corresponding to the determination of the appropriate temperature range.

Prvi od tehničnih problemov, ki ga rešuje naš izum je vključitev temperaturnega senzoija v embalažo neposredno v proizvodni liniji. Tisk prevodnih linij se izvede s pomočjo ene od konvencionalnih tehnologij tiska (najpogosteje sitotisk ali fleksotisk), lahko pa tudi z digitalno tehnologijo tiska (kapljični tisk, elektrofotografija) z uporabo funkcionalne prevodne tiskarske barve oziroma črnila v primeru uporabe kapljičnega tiska ali prevodnega tonerja pri uporabi elektrofotografije.The first of the technical problems that our invention solves is the integration of the temperature sensor in the packaging directly in the production line. Conductive line printing is performed using one of the conventional printing technologies (most commonly screen printing or flexographic printing), but also digital printing technology (droplet printing, electrophotography) using a functional conducting printing ink or ink when using droplet printing or conductive toner when used electrophotographs.

Drugi od tehničnih problemov, ki ga rešuje naš izum je izključitev potrebe po dodatni zaščiti senzoija, saj laminimi zgornji sloj dovolj zaščiti senzor in omogoči povečanje trajnosti.Another technical problem that our invention solves is the exclusion of the need for additional sensor protection, since the laminate top layer sufficiently protects the sensor and allows for increased durability.

• ·• ·

Tretja rešitev je vezana na možnost potiska laminimega sloja. S tem se izboljša vizualni izgled embalaže.The third solution relates to the possibility of pushing the laminate layer. This improves the visual appearance of the packaging.

Ker se senzor izdela v proizvodni liniji z eno od dodajalnih, aditivnih tehnologij tiska, se nanese le toliko prevodne tiskarske barve, kot jo potrebujemo za izdelavo senzorja. Na ta način izum rešuje četrti tehnični problem.Because the sensor is manufactured in a production line with one of the additive, additive printing technologies, only the conductive printing ink required to produce the sensor is applied. In this way, the invention solves the fourth technical problem.

Zaradi zaščite senzoija z laminimim slojem se posledično rešuje peti tehnični problem, saj je obremenitev za okolje zaradi večje trajnosti oziroma večkratne uporabnosti embalaže manjša.Due to the protection of the laminate layer sensorium, the fifth technical problem is consequently solved, as the environmental burden is reduced due to the increased durability or repeated use of the packaging.

3. Stanje tehnike3. State of the art

Podobnih patentov, kot jih rešuje naš izum v slovenski in v svetovnih patentnih bazah nismo našli. Veliko je patentov na področju inteligentne embalaže, ki vključujejo več-senzome sisteme, katerih komunikacija je lahko osnovana na RFID sistemu. Med njimi izpostavimo US 7755489 B2 in US 6922664 BI, ki predstavljata inteligentne sisteme z vrsto senzorjev (senzor pritiska, temperaturni senzor in enega ah več kemičnih senzorjev, ki merijo fizikalne komponente vsebine embalaže). Naš predhodni sistem opisan v patentni prijavi P-201300019; Embalaža iz kartona z vgrajeno pametno značko za radiofrekvenčno identifikacijo z možnostjo beleženja različnih parametrov lahko služi kot osnova za zamenjavo konvencionalnega merilnega sistema pri novem izumu.We have not found any similar patents to our invention in Slovenian and worldwide patent bases. There are many patents in the field of intelligent packaging that include multi-sensor systems whose communication can be based on an RFID system. These include US 7755489 B2 and US 6922664 BI, which represent intelligent systems with a range of sensors (pressure sensor, temperature sensor and one or more chemical sensors that measure the physical components of the contents of the packaging). Our preliminary system is described in patent application P-201300019; Cardboard packaging with a built-in RFID tag with the ability to record different parameters can serve as a basis for replacing a conventional measuring system with a new invention.

Na področju tiskanih temperaturnih senzoijev smo našli veliko objav, a nobena ni podobna našemu izumu. WO2013114293 (Al), opisuje izdelavo velikoformatnega tiskanega temperaturnega senzoija, ki je narejen iz mreže enakih temperaturno odvisnih uporov. Drugi patent s področja tiskanih temperaturnih senzorjev EP2616784 (Al), predstavlja metodo za izdelavo temperaturnega senzoija, ki ima strukturo in funkcijo termistoija. Metoda vključuje tisk s tiskarsko barvo na osnovi silicijevega dioksida. Omogoča meritev temperature podlage oziroma tiskovnega materiala na katerega je senzor natisnjen, ah pa se uporabi kot zunanji senzor. Izvedba je zahtevnejša, kot v primeru našega patenta, kjer je uporabljena prevodna barva za tisk prevodnih linij, oziroma spiral, ki tvorijo senzor.We have found many publications in the field of printed temperature sensors, but none are similar to our invention. WO2013114293 (Al), describes the manufacture of a large-format printed temperature sensor made from a network of identical temperature-dependent resistors. The second patent in the field of printed temperature sensors EP2616784 (Al), is a method for making a temperature sensor having the structure and function of a thermistor. The method involves silicon-based printing ink. It allows to measure the temperature of the substrate or the printed material on which the sensor is printed and can be used as an external sensor. The implementation is more demanding than in the case of our patent, where the conductive ink is used to print the conductive lines, or the spirals that make up the sensor.

4. Opis bistva izuma4. Description of the invention

Prednosti tiskanih senzorjev je veliko. Izdelava senzoijev je okolju prijaznejša od do sedaj poznanih, ki se večinoma izdelujejo po subtraktivnem načinu (jedkanje ah vroči tisk s prevodno folijo). Tehnologije tiska pa omogočajo tisk senzoijev z aditivnim načinom, kar pomeni velik prihranek porabe prevodnih materialov, tiskarskih barv, folij, kot tudi zmanjšanje odpadkov nastalih pri izdelavi senzoijev.The benefits of printed sensors are many. Sensoi production is more environmentally friendly than previously known ones, most of which are manufactured in a subtractive manner (etching ah hot press with conductive foil). Printing technologies, however, allow the printing of sensoes in an additive manner, which means a great saving on the consumption of conductive materials, printing inks, films, as well as the reduction of waste generated in the production of sensoi.

Na osnovi ugotovljenega stanja tehnike smo potrdili veliko prednosti postopka izdelave tiskanih temperaturnih senzoijev za namen uporabe pri pametni embalaži po opisanem izumu, ki se kažejo predvsem v enostavnosti in zanesljivosti postopka in cenejši oziroma hitrejši realizaciji, hkrati pa dodajo interaktivnost in veliko dodano vrednost končnemu izdelku - embalaži, saj povečajo oziroma razširijo njeno uporabnost.Based on the state of the art, we have confirmed many advantages of the process of manufacturing printed temperature sensors for the purpose of use in smart packaging according to the described invention, which are manifested mainly in the simplicity and reliability of the process and cheaper or faster realization, while adding interactivity and great added value to the finished product - packaging as they increase or extend its usefulness.
