Tehnićki problem Technical problem

U domaćinstvu se često događa da otvorimo vrećice iz kojih izvadimo jedan dio sadržaja, a onda vrećice zatvaramo na razne načine, a obično presavijanjem gornjeg dijela vrećice ili kvačicom za robu. Treba tehnički riješiti zatvaranje vrećice na način da se posebnim zatvaračem obuhvati gornji otvoreni dio vrećice i tako sačuva kvaliteta i aroma ostatka sadržaja u vrećici. Zatvarač po potrebi može imati i dodatak za vješanje o klin. In the household, it often happens that we open the bags from which we take out part of the contents, and then we close the bags in various ways, usually by folding the upper part of the bag or using a clothespin. The closure of the bag should be solved technically in such a way that the upper open part of the bag is covered with a special closure and thus preserves the quality and aroma of the rest of the contents in the bag. If necessary, the fastener can also have an attachment for hanging on a peg.

Stanje tehnike State of the art

Nije poznato da postoje zatvarači za zatvaranje vrećica čiji se sadržaj koristi više puta, posebno u domaćinstvu. Taj problem domaćice rješavaju na razne načine. Najčešće presaviju ostatak vrećice i tako odlože u smočnicu, ili gornji otvoreni dio vrećice stegnu sa kvačicom za robu. Oba ova postupka ne osiguravaju hermetičnost što uzrokuje gubitak arome i slabljenje kvalitete ostatka sadržaja u vrećici, naročito kave. It is not known that there are closures for closing bags whose contents are used more than once, especially in the household. Housewives solve this problem in various ways. Most often, they fold the rest of the bag and put it in the pantry, or they clamp the upper open part of the bag with a clothespin. Both of these procedures do not ensure hermeticity, which causes the loss of aroma and the weakening of the quality of the rest of the content in the bag, especially the coffee.

Bit izuma The essence of invention

Bit izuma je u tome da zatvarač za vrećice sa oba izdanka na dužem dijelu hvata i savija oba kraja ostatka vrećice i pri tome, slično kao i kvačica, čvrsto stegne krajeve vrećice. Na ovaj način otvorena vrećica se može višekratno upotrebljavati bez posljedica za gubitak kvalitete sadržaja vrećice. Zatvarač može imati dodatak za vješanje vrećice radi preglednosti i boljeg korištenja prostora u stanu. The essence of the invention is that the closure for bags with both shoots on the longer part catches and bends both ends of the rest of the bag and, similarly to a hook, tightly clamps the ends of the bag. In this way, the opened bag can be used multiple times without any consequences for the loss of the quality of the contents of the bag. The zipper can have an attachment for hanging the bag for visibility and better use of space in the apartment.

Opis načina ostvarivanja izuma Description of the method of realization of the invention

Zatvarač za vrećice, prema ovom izumu, sastoji se od krila 1 koji su spojeni opnom 3 sa uzdužnim nosačima zubi 2, uzdužnih krajnih ojačanja krila 4 i omče za vješanje 5. The closure for bags, according to this invention, consists of wings 1, which are connected by a membrane 3 to longitudinal tooth supports 2, longitudinal end reinforcements of the wings 4 and a loop for suspension 5.

Zubi mogu biti izrađeni u obliku slova L 6 sa nazubljenim krajevima 7, te sa konveksnim 8 i konkavnim oblikom 9. The teeth can be made in the shape of the letter L 6 with serrated ends 7, and with convex 8 and concave shape 9.

Zatvarač za vrećice, prema sl. 1., 2. i 3., ima dva krila i koja su međusobno spojena tankom stijenkom - opnom 3, dok su krajnji bridovi krila 4 ojačani, prema sl. 5. Na središnjem dijelu krila uzdužno su napravljeni nosači zubi 2 za držanje vrećica. Nosači sa zubima su podešeni tako da je Jedan u odnosu na drugi pomaknuti za debljinu nosača zubi. Zatvarač može imati omču za vješanje zatvarača sa ili bez vrećice. The closure for bags, according to Fig. 1, 2 and 3, has two wings, which are connected to each other by a thin wall - membrane 3, while the end edges of wing 4 are reinforced, according to Fig. 5. On the central part of the wing, longitudinally tooth holders 2 for holding bags. The supports with teeth are adjusted so that one tooth is shifted in relation to the other by the thickness of the support. The closure can have a loop for hanging the closure with or without a bag.

Izum funkcionira na slijedeći način: kad se krila zatvarača pritisnu jedan uz drugi, nosač zubi i zubi preskoče jedan preko drugoga i na taj način ostvare spoj koji čvrsto drži predmet između zubi. The invention works in the following way: when the shutter wings are pressed against each other, the carrier teeth and the teeth jump over each other and in this way achieve a connection that firmly holds the object between the teeth.

Prema sl. 9. prikazano je kako zatvarač presavije vrh odrezane vrećice 10 i kako zubi 2 drže vrećicu da ne može ispasti sve dok krila zatvarača 1 ne razmaknemo, Na ovaj način postignemo skoro hermetičko zatvaranje vrećice. Tanka stijenka - opna 3 je elastična i prilagođena višekratnom otvaranju i zatvaranju krila zatvarača. According to Fig. 9, it is shown how the closure folds the top of the cut bag 10 and how the teeth 2 hold the bag so that it cannot fall out until the wings of the closure 1 are separated. In this way, we achieve an almost hermetic closure of the bag. Thin wall - membrane 3 is elastic and adapted to multiple opening and closing of shutter wings.

Primjena izuma Application of the invention

Zatvarač za vrećice, prema ovom izumu, nalazi svoju primjenu, kako u domaćinstvu, tako i na drugim mjestima gdje se sadržaj vrećica odmah ne koristi u cijelosti (škole, domovi, odmarališta, bolnice i dr.). Ovakvi zatvarači se mogu uspješno primijeniti u industriji za zatvaranje vrećica različitog sadržaja. The bag sealer, according to this invention, finds its application both in the household and in other places where the contents of the bags are not immediately used in their entirety (schools, homes, resorts, hospitals, etc.). Such closures can be successfully used in the industry for closing bags of different contents.

Izrada zatvarača za vrećice je jednostavna i jeftina. Najbolje je izrađivati zatvarač od plastičnih materijala koji mogu izdržati višekratno otvaranje i zatvaranje. Materijal zatvarača treba biti ekološki prilagođen uvjetima za upotrebu u domaćinstvima. Making bag closures is simple and cheap. It is best to make the closure from plastic materials that can withstand repeated opening and closing. The closure material should be ecologically adapted to the conditions for use in households.

Zatvarač se može primijeniti na vrećicama od različitog materijala. The closure can be applied to bags made of different materials.
