Description

TARIFNAME BIR AMBALAJ KAPATMA YÖNTEMI VE AMBALAJ KAPAGI TEKNIK ALAN Bulus, polipropilen gida ambalaji kapatma yöntemi ve bu yöntemde kullanilmak üzere yeni bir kapak ile ilgilidir. ÖNCEKI TEKNIK Piyasada mevcut durumda 118mm, 132 mm, 160 mm çaplarinda polipropilen malzemeden mamul gida ambalajlari kullanilmaktadir. Söz konusu gida ambalajlari genellikle yogurt vb gida ürünlerinde kullanilmaktadir. Özellikle yogurt üretiminde yogurdun mayalanmasi söz konusu pp ambalaj içerisinde gerçeklestirilmekte olup seri üretim sirasinda ambalajin üzerinin hava sizdirmazligi saglanmasi amaci ile folyo ile kapatilmaktadir. Folyonun üzeri ise ikincil koruma saglamak ve folyo çikartildiktan sonra ürünün üzerinin kapatilmasi için açilip yeniden kapatilabilen kapak ile kapatilmaktadir. Kullanici önce dis kapagi açmakta ve akabinde folyoyu çikartmasi sureti ile ürünü tüketebilmektedir. Daha sonra dis kapagi kapatarak Bilinen teknikte polipropilen ambalajin üzeri folyo ile kaplanirken, ambalajin sahip oldugu agiz açikliginin üzerine folyo konumlanmakta ve bahsedilen folyoya ambalaj ile temas ettigi bölgeler öncelikli olmak üzere isi uygulanmaktadir. Bu sayede folyo ile ambalajin birbiri ile kaynaklanmasi/yapismasi saglanarak hava geçirgenligi ve sizdirma sorunlari engellenmektedir. DESCRIPTION A PACKING CLOSING METHOD AND PACKING COVER TECHNICAL FIELD The invention is a method of closing polypropylene food packaging and for use in this method. It's about a new cover. PRIOR ART Polypropylene available in the market in diameters of 118mm, 132mm, 160mm Food packaging made of material is used. The food packaging in question It is generally used in yogurt etc. food products. Especially in the production of yogurt, the fermentation of the yogurt is in the pp package. Airtightness of the packaging is carried out during mass production. It is closed with foil in order to ensure Secondary protection on the foil To ensure that the product is covered and to cover the product after the foil is removed, it must be opened and re-opened. It is closed with a closable lid. The user first opens the outer cover and then can consume the product by removing the foil. Then by closing the outer cover In the prior art, while the polypropylene package is covered with a foil, the The foil is placed over the mouth opening and the said foil is placed with the packaging. heat is applied, primarily the areas it comes into contact with. In this way, the foil air permeability and adhesion by ensuring that the packaging is welded/adhered to each other. Leakage problems are prevented.

Bilinen teknikteki uygulamada polipropilen ambalajin üzerine kaplanan folyo polipropilen malzeme olup üzerine isi uygulandiginda güvenli bir sekilde iki ürünün birbiri ile yapismasi saglanmaktadir. Ambalaj üzerine kapatilan dis kapak ise genellikle polietilen malzemedir. Söz konusu malzeme sert, esneyebilen yapida oldugu için ambalajin kapagina birçok defa takilip çikartilabilmektedir. In the prior art application, the foil coated on the polypropylene package It is a polypropylene material and when heat is applied on it, two products can be safely are provided to adhere to each other. The outer cover closed on the packaging is usually It is polyethylene material. Since the material in question is of a hard, stretchable structure, It can be attached and removed from the cover of the package many times.

Yukaridaki bilinen teknikteki uygulamalarda en temel sorun ambalaji kapatmak için iki proses sirasinda folyo ve kapak için iki defa kapatma eylemi gerçeklestirilmektedir. The most basic problem in the above prior art applications is that there are two ways to close the package. During the process, two closing actions are performed for the foil and the lid.

Ayrica folyo ve kapak kullanimi ambalaj maliyetini artiran bir diger etmendir. In addition, the use of foil and lid is another factor that increases the packaging cost.

Sonuç olarak yukarida bahsedilen tüm sorunlar, ilgili alanda bir yenilik yapmayi zorunlu hale getirmistir. As a result, all the above-mentioned problems make it necessary to make an innovation in the relevant field. does not make it.

BULUSUN AMACI Mevcut bulus, yukarida bahsedilen problemleri ortadan kaldirmak ve ilgili alanda teknik bir yenilik yapmayi zorunlu kilmaktadir. OBJECTIVE OF THE INVENTION The present invention aims to eliminate the above-mentioned problems and necessitates innovation.

Bulusun ana amaci yogurt vb gidalarin ambalajlanmasinda kullanilan kaplarda, kabin üzerine folyo kaynatilmasi ve sonrasinda kapak konumlandirilmasini ortadan kaldirarak direkt olarak kolay açilir bir sekilde kapagin kaynatilmasina olanak taniyan kapak yapisini ortaya koymaktir. The main purpose of the invention is in containers used in the packaging of yogurt etc. It eliminates welding foil on it and then positioning the lid. allowing the lid to be welded in an easy-to-open way directly by lifting it. to reveal the cover structure.

Bulusun bir diger amaci, üretim sirasinda, bantta islem istasyonu sayisinin azaltilmasini saglamaktir. Another object of the invention is to increase the number of processing stations on the band during production. is to reduce it.

Bulusun bir diger amaci ambalajlama maliyetinin azaltilmasini saglamaktir. Another object of the invention is to provide a reduction in packaging cost.

Bulusun bir diger amaci, ambalajlama sirasinda tedarik edilecek ürün sayisinin azaltilmasini saglamaktir. Another object of the invention is to determine the number of products to be supplied during packaging. is to reduce it.

Bulusun bir diger amaci gida güvenligine uygun ikiden fazla ürün tedarigine ihtiyaci ortadan kaldirmaktadir. Bulus sayesinde yalnizca kap ve kapak temin edilerek sizdirmaz ürün elde edilebilmektedir. Another object of the invention is the need to supply more than two food-safe products. it eliminates. Thanks to the invention, only the container and lid can be provided. leak-proof product can be obtained.
