CLASS 42 i: 11/06 INT. CLASS G 01 k PATENT PERIOD FROM NOVEMBER 7, 1955 GRANTED ON JUNE 8, 1961 PUBLISHED ON AUGUST 15! 1961 Ans. The present invention relates to feeding devices and relates to such for the purpose of specifying a temperature separately for the purpose of specifying a separate temperature. . in standard packaged frozen goods suitable device.

Vid forvaring av frysgods kan en avsevard skillnad uppsta mellan frysgodsets och den omgivande luftens temperatur, sa'val dâ frysgodset skall nedkylas genom bortfOring av varme fran detsamma som da en lamplig skyddande temperatur skall bibehallas hos frysgodset. Sarskilt da frysgods forvaras i sa.dana oppna frysboxar och frysdiskar, som tillampas t. ex. i snabbkopsaffarer, dar utrymmet narmast over frysgodset star i direkt forbindelse med den omgivande lokalen, är det namnda forhallandet framtradande. Medan temperaturen hos salunda forvarat frysgods normalt är betydligt under fryspunkten, kan ett luftskikt narmast Over frysgodset myeket val ha en temperatur Over densamma. Vid kontroll av temperaturen hos frysgods kan man darfor joke nOj a sig med att mata temperaturen hos den narmast omgivande luften utan bOr om m8jligt ordna sa, att matanordningen eller dess temperaturkansliga organ Or paverkat av samma termiska forbAllanden som frysgodset. When storing frozen goods, a considerable difference can arise between the temperature of the frozen goods and the ambient air, so that when the frozen goods are to be cooled by removing heat from the same as when a suitable protective temperature is to be maintained in the frozen goods. Especially when frozen goods are stored in such open freezer boxes and freezer counters, which are applied e.g. in supermarket stores, where the space closest to the freezer is in direct connection with the surrounding premises, the said relationship is prominent. While the temperature of saluna stored frozen goods is normally significantly below the freezing point, an air layer close to the freezer compartment can very often have a temperature above it. When checking the temperature of frozen goods, one can therefore be content to feed the temperature of the nearest ambient air without having to arrange, if possible, so that the feeding device or its temperature-sensing means are affected by the same thermal conditions as the frozen goods.

Avsikten med foreliggande uppf inning Or att ange en sarskilt for bestamning av temperaturen hos standardforpackat frysgods lamp-hg anordning, vilken motsvarar de I det foregaende antydda kraven, samtidigt som den Or relativt enkel att framstalla och bekvam att anvanda. The object of the present invention is to provide a special for determining the temperature of a standard packaged freezer lamp-hg device, which corresponds to the requirements indicated above, while at the same time being relatively simple to manufacture and convenient to use.

En enligt uppfinningen utfOrd anordning, I det foljande benamnd matkropp, kan utr &as av ett yttre holje, en behallare, ett fordrojningsmedel och en temperaturmatanordning eller ett temperaturimpulsorgan samverkande med en sarskild matanordning. En. eller flera dylika matkroppar placeras bland avsett standardforpackat frysgods, vars tem.- peratur skall kontrolleras. A device according to the invention, hereinafter referred to as a food body, can be formed by an outer casing, a container, a dispersant and a temperature food device or a temperature impulse means cooperating with a special food device. One. or several such food bodies are placed among the intended standard-packed frozen goods, the temperature of which must be checked.

Det namnda yttre holj et till en matkropp kan enligt uppfinningen med hansyn till si na dimensioner och termiska egenskaper sluta sig till namnda egenskaper hos emballaget till avsett frysgods och vara antingen utbytbart eller utfort att motsvara de fOrdringar, t. ex. i fraga om hygien och hallbarhet, vilka kunna stallas pa ett mera permanent holje. Sasom material kan kartong, plast eller dylikt ifragakomma. Vid en matkropp forsedd med en fullstandig temperaturmatanordning skall ett joke genomskinligt yttre holje vara forsett med ett Master, genom vilket temperaturmatanordningens utslag kan avlasas. According to the invention, the said outer casing of a food body can, in view of its dimensions and thermal properties, conclude with the said properties of the packaging for the intended frozen goods and be either replaceable or designed to correspond to the requirements, e.g. in terms of hygiene and durability, which can be placed on a more permanent housing. As a material, cardboard, plastic or the like can be used. In the case of a food body provided with a complete temperature food device, a transparent outer shell of a joke must be provided with a Master, through which the rash of the temperature food device can be unloaded.

Inuti det namnda yttre holjet kan enligt uppfinningen den namnda behallaren vara anordnad sa, att den utfyller hela holjet eller en lamplig del av detsamma. Behallarens som valjes med hansyn till dess uppgift, kan utgoras av metall eller plast eller dylikt och kan i det senare fallet t. ex. utgOras av genomskinligt plexiglas. Behallaren skall vara tillslutbar, t. ex. medelst en. eller flera tatt slutande forskruvningar. Det Or aven tankbart att giva en dylik behallare de for en viss matkropp avsedda yttre dimensionerna och a.nvanda den utan nagot sarskilt yttre hölj e, sarskilt da behallarens material utgores av plast eller dylikt. Inside the said outer cover, according to the invention, the said container can be arranged such that it fills the entire cover or a suitable part thereof. The container which is selected with regard to its task, may be made of metal or plastic or the like and may in the latter case e.g. is made of transparent plexiglass. The container must be closable, e.g. by means of a. or several closed screws. It is also conceivable to give such a container the external dimensions intended for a certain food body and to use it without any special outer casing, especially since the material of the container is made of plastic or the like.

Det namnda fordrojningsmedlet avser enligt uppfinningen att motsvara varmekapaciteten hos en avsedd frysgodsforpackning och bor i ovrigt vara anpassat till de termiska egenskaperna hos frysgodset. Vid frysgods med relativt stor vattenhalt, sasom bar, gransaker, fisk eller kat, kan man salunda som fordrojningsmedel anvanda en eutektisk losfling med samma fryspunkt som frysgodset, medan man vid frysgods, som icke har flagon utpraglad fryspunkt, sasom margarin och smor, kan anvanda en eutektisk 18sning med lagre fryspunkt an den avsedda forvaringstemperaturen eller andra amnen, t. ex. paraffinolja, sprit, glycerin eller paraffin. Fordrojningsmedel i flytande tillstand forvaras i den i det fOregaende namnda behallaren, varvid tillses, att ett lampligt expansionsutrymme aterstar. Vid ett fast f8rdrojningsmedel, sa.- som paraffin, kan en sarskild behallare for 2— — fordrojningsmedlet undvaras, och fordrojningsmedlet anordnas i stallet omedelbart i det namnda yttre holjet. According to the invention, the said dispersant is intended to correspond to the heat capacity of an intended frozen goods package and should otherwise be adapted to the thermal properties of the frozen goods. In the case of frozen goods with a relatively high water content, such as bar, spruce, fish or cat, a eutectic release flake with the same freezing point as the frozen material can be used as a dispersant, while in the case of frozen goods which do not have a pronounced freezing point, such as margarine and butter. a eutectic solution with lower freezing point at the intended storage temperature or other substances, e.g. paraffin oil, spirits, glycerin or paraffin. Liquid dispersants are stored in the above-mentioned container, ensuring that a suitable expansion space remains. In the case of a solid dispersant, such as paraffin, a special container for the dispersant can be dispensed with, and the dispersant is arranged in the stable immediately in the said outer shell.

Den namnda temperaturmatanordningen kan enligt uppfinningen utgoras av en termometer av konventionell typ och for andamalet I.ampad storlek, t. ex. en glastermometer, vars kapillarror och skala anordnats i ett tillsmalt glasror. En. dylik termometer kan i ett sadant Ml, dd saval behallare som fOrdrajningsmedel are genomskinliga, anordnas inuti behalLaren med skalan vand sa, att den kan avidsas utifran genom det nam.nda fenstret i det yttre holjet. Det ar aven tankbart att anvanda flera term.ometrar, t. ex. en maximi- och en minimitermometer i samma matkropp. Ar fordrojningsmedlet ogenomskinligt, kan man lilla detsamma eller behallaren upptaga endast en del av det yttre hOljet, sa att plats finnes for termometern eller dess avlasningsdel bredvid namnda fordri3jningsmedel eller behallare, varvid termometerns impulsorgan anordnas i termisk farbindelse med fordrojningsmedlet. According to the invention, the said temperature feeding device can be constituted by a thermometer of conventional type and for the purpose of the specified size, e.g. a glass thermometer, the capillary tubes and scale of which are arranged in a narrowed glass tube. One. Such a thermometer can be arranged inside a container with the scale water so that it can be devised from the outside through the so-called window in the outer casing. It is also conceivable to use several thermometers, e.g. a maximum and a minimum thermometer in the same food body. If the displacement means is opaque, the same or the container can occupy only a part of the outer casing, so that there is space for the thermometer or its unloading part next to said displacement means or container, the impulse means of the thermometer being arranged in thermal communication with the displacement means.

En dylik direkt avlasbar matkropp bOr anvandas endast vid latt tillgangliga matstallen, sa att den utan svarighet kan uttagas for avlasning. Vid mera svaratkomliga matstallen kir en. avstandstermometer av nagot slag anordnas sa, att dess impulsorgan befinner sig matkroppen I beroring med fordrOjningsmedlet, medan dess matorgan placeras ldtt atkomligt for avlasning. Forbindelsen mellan impuls- och matorgan kan vara anordnad pa konventionellt satt medelst en ledning for gaseller vatsketryck eller f6r en elektrisk stromkrets, och matorganet kan aven vara forsett med anordning for registrering. Such a directly unloadable food body should only be used at easily accessible food stalls, so that it can be removed for unloading without responsibility. At more responsible dining stalls, one. distance thermometers of some kind are arranged so that its impulse means is in contact with the food body with the dispersant, while its food means are placed easily accessible for unloading. The connection between impulse and supply means can be arranged in a conventional manner by means of a line for gas or liquid pressure or for an electric circuit, and the supply means can also be provided with a device for registration.

Vid anvan.dningen placeras en eller flera enligt uppfinningen anordnade matkroppar bland avsett frysgods, varvid man efter onskan kan valja matstationer it. ex. med hansyn till forutsedd hogsta resp. lagsta temperatur hos frysgodset. Vid lampligt val av yttre holje resp. fOrdrOjningsmedel kommer temperaturen hos en matkropp att folja temperaturforandringen hos omgivande frysgods, 1. ex. vid nedfrysning och vid eventuell avfrostning av f8rvaringsanordningen. Nar en matkropp fOrsedd med inbyggd termometer uttages for avlasning och darvid utsattes for paverkan av en hogre omgivande ternperatur, uppstar ph grund av fordrojningsmedlets varmekapacitet icke flagon omedelbart markbar forandring av dess utslag, som dart& ger en tillfOrlitlig uppgift om frysgodsets temperatur. During use, one or more food bodies arranged according to the invention are placed among the intended frozen goods, whereby food stations can be selected as desired. ex. with regard to anticipated felling resp. lowest temperature of the frozen goods. In the case of a suitable choice of outer casing resp. Discharge agent, the temperature of a food body will follow the temperature change of the surrounding freezer, 1. ex. in the event of freezing and in the event of defrosting of the storage device. When a food body equipped with a built-in thermometer is taken out for unloading and thereby exposed to the influence of a higher ambient temperature, the heat capacity of the dispersant does not immediately cause a noticeable change in its rash, which gives a reliable indication of the temperature of the freezer.

Ehuru en matkropp enligt uppfinningen narmast dr avsedd for trysm5bler av i det RSregaende angivet slag, ar det tankbart, att den. kan befinnas lamplig 5.ven i andra fall, t. ex. for kylskap, kylrum och kyl- eller fryslager, dar standardforpackat gods forvaras. Dess tillampning kan icke heller anses begransad till anordningar avseende livsmedel, utan frys- eller kylgodset kan t. ex. utgoras av medicinska preparat, kosmetiska medel eller dylikt. Although a food body according to the invention is most closely intended there for furniture of the type specified in the RS, it is conceivable that it. may be found suitable 5.ven in other cases, e.g. for refrigerators, cold rooms and cold or freezer storage, where standard packaged goods are stored. Its application can also not be considered limited to devices concerning food, but the frozen or refrigerated goods can e.g. consists of medicinal preparations, cosmetics or the like.

Till upptinningens fortydligande visas a bifogad ritning sasom ett exempel pa dess tilllampning i schematisk framstallning en enligt uppfinningen utt8rd rektangular matkropp av det slag, somu ar fOrsedd med en termometer anordnad i en genomskinlig behallare innehallande en eutektisk lasning. Ritningen visar i fig. 1 matkroppen skuren i ett plan yinkelratt mot dess sidoytor och i fig. 2 samma anordning skuren i ett med sidoytorna parallellt plan. To clarify the thawing, the accompanying drawing shows as an example of its application in schematic representation a rectangular food body of the type according to the invention, which is provided with a thermometer arranged in a transparent container containing a eutectic reading. The drawing shows in Fig. 1 the food body cut in a plane perpendicular to its side surfaces and in Fig. 2 the same device cut in a plane parallel to the side surfaces.

Anordningen enligt ritningen bestar av ett rektangulart yttre halje 10 av kartong, plast eller dylikt, forsett med ett Muster 11 astadkommet darigenom att en del av holj et borttagits. Det namnda holjet 10 omsluter en holjet utfyllande, genomskinlig behallare 12 av iilexiglas eller dylikt, innehallande en eutektisk losning 13. Behallaren 12 ar IA en kortsida fOrsedd med en inatgfiende vb.rta 14 utford i behallarens material och fOrsedd med ett genomgaende gangat hal for en med motsvarande ganga fOrsedd propp 15. Namnda propp 15, som titter emot behallaren 12 medelst en plan flans 16 och en ringformad packning 17, ar fOrsedd med en mat behallaren oppen cylindrisk ficka 18, i vilken den ena anden av en glastermometer 19 fasthalles medelst en mellan namnda ficka och termometer anordnad elastisk hylsa 20, expanderad medelst en i proppen 15 gangad presshylsa 21. Vid fastsattningen av termometern 19 iakttages, att dess skala blir vand emot del namnda fOnstret 11, dd proppen 15 fastskruvas i behillaren 12. The device according to the drawing consists of a rectangular outer cover 10 of cardboard, plastic or the like, provided with a Pattern 11 provided by removing a part of the cover. The aforementioned housing 10 encloses a housing filling, transparent container 12 of lacquered glass or the like, containing a eutectic solution 13. The container 12 is a short side provided with an intact surface 14 deflected in the material of the container and provided with a continuous passageway for a The corresponding plug 15, which plugs against the container 12 by means of a flat flange 16 and an annular gasket 17, is provided with a food container open cylindrical pocket 18, in which one end of a glass thermometer 19 is held by means of a between the said pocket and the thermometer arranged elastic sleeve 20, expanded by means of a press sleeve 21 threaded in the plug 15.

Vid anvandningen i I. ex. en for standardforpackat frysgods avsedd frysdisk av en enligt uppfinningen anordnad matkropp, placeras denna i stallet fOr en dylik standardforpackning pa en sadan plats i frysdisken, vars temperatur man anser vara av sarskilt intresse, t. ex. dar man kan forutse, att den bor vara hogre an pa andra stallen, sasom i ett Ovre skikt och nara ett yttre horn. Efter nagon Lid, som berfiknas atga for utjamning av temperaturen mellan omgivande frysgods och rnatkroppen, kan denna uttagas for avlasning. Den i lokalen, dar avlasningen sker, radande temperaturen her darvid ingen betydelse, emedan utslaget hos fryskroppens termometer pa grund av fordrojningsmedlets varmekapacitet icke hinner paverkas mark-hart under en sd kort tidsintervall, soul erfordras for en avlasning. When used in I. ex. a freezer counter intended for standard-packaged frozen goods of a food body arranged according to the invention, this is placed in place of such a standard packaging in such a place in the freezer counter, the temperature of which is considered to be of particular interest, e.g. where it can be foreseen that it should be higher than in other places, as in an upper layer and near an outer horn. After a Lid, which is calculated to equalize the temperature between the surrounding freezer and the body, it can be taken out for unloading. The temperature in the room where the unloading takes place does not matter here, since the rash of the freezer thermometer due to the heat capacity of the dispersant does not have time to be affected hard during such a short time interval, soul is required for a unloading.

En. dylik anordning enligt uppfinningen kan mom ramen for uppfinningstanken varieras pa flera satt, utan att uppfinningens ide fraugas. Man kan t. ex. vid sadana fall, da Overvakning av frysgodsets temperatur anses onskvard aven da personal fOr avlasning icke ar tillganglig. anvanda sig av en. matkropp — —3 forsedd med kontakttermometer, vilken f8r nigon avsedd, icke onskad temperatur kan via en larmkrets pakalla undsfittning. En matkropp enligt uppfinningen ger harvid den fordelen, att larm icke erhfilles i on5dan utan forst di frysgodsets temperatur narmar sig grOnsen for tillatna virden. Det ãr tthikbart att arivanda matkroppar anordnade enligt uppfinningens princip aven for andra andamai och andra matomraden an kylteknikens. One. Such a device according to the invention can be varied within the scope of the inventive idea in several ways, without questioning the idea of the invention. One can e.g. in such cases, when Monitoring of the temperature of the frozen goods is considered necessary even when personnel for unloading are not available. make use of a. food body - —3 equipped with a contact thermometer, which for nigon intended, undesired temperature can via an alarm circuit pakalla escape. A food body according to the invention has the advantage that alarms are not received in the air but only when the temperature of the frozen goods approaches the limit of permissible values. It is conceivable that according to the principle of the invention, various food bodies are also provided for other andamai and other food areas other than the refrigeration technique.
