Abstract
Description
Uprawniony z patentu: Dart Industries Inc., Los Angeles, Kalifornia (Stany Zjednoczone Ameryki) Odksztalcalne sprezyscie zamkniecie cylindrycznego pojemnika Przedmiotem wynalazku jest odksztalcalne spre¬ zyscie zamkniecie cylindrycznego pojemnika, który na obrzezu ma kolnierz uszczelniajacy przylegajacy do wewnetrznej scianki pojemnika. Wynalazek do¬ tyczy zamkniecia z termoplastycznego tworzywa 5 sztucznego, przeznaczonego do wielokrotnego uzycia w pojemniku o otwartym wylocie.Znane sa zamkniecia pojemników do przecho¬ wywania zywnosci, w tym równiez wykonane z termoplastycznych tworzyw sztucznych. Skladaja 10 sie one na ogól z cylindrycznego naczynia lub z naczynia o ksztalcie pucharu, kielicha, stozka ito. oraz oddzielnego zamkniecia lub pokrywy, wyko¬ nanej z materialu stosunkowo sprezystego. Jedne z nich posiadaja tasme obwodowa, która umieszcza sie 15 na górnej krawedzi scianki pojemnika i wciska sie na te krawedz w celu szczelnego zamkniecia obu elementów pojemnika. Zastosowanie takiego zam¬ kniecia wymaga zwykle wywarcia przez uzytkow¬ nika nacisku pokrywy w kilku miejscach w celu skutecznego osadzenia jej na pojemniku. Niemiecki opis patentowy 1225544 dotyczy puszki z tworzywa sztucznego, której dno jest wklesle na skutek uksztaltowania jego skosnych plaszczyzn. Dno to normalnie jest mocno polaczone z druga puszka.Rozlaczenie mozliwe jest tylko wtedy, gdy od wne¬ trza puszki przylozy sie sile do dna, co w przypad¬ ku puszki zamknietej ze wszystkich stron i po¬ siadajacej jedynie niewielki otwór jest niemozli¬ we bez uzycia specjalnego narzedzia. Wsród innych 30 20 odmian znajduja sie zamkniecia typu korka oraz rozpierane, które wchodza luzno do otworu pojem¬ nika, i które nastepnie rozpiera sie az do styku z wewnetrzna powierzchnia scianek pojemnika.Powyzsze zamkniecia wykazuja szereg niedogod¬ nosci i ulegaja latwemu wypaczeniu na skutek braku sztywnosci, a umieszczenie wypaczonej po¬ krywy na pojemniku staje sie oczywiscie trudniej¬ sze, a czasem nawet niemozliwe. W zamknieciach wy¬ zej wspomnianych typów ograniczony jest równiez w pewnym stopniu zakres stosowania materialów i wymiarów zamkniecia, jak grubosc scianek, sre¬ dnica itd.Celem wynalazku jest wykonanie zamkniecia cy¬ lindrycznego pojemnika, którego wciskana pokrywa posiadac bedzie zwiekszona elastycznosc i szczel¬ nosc.Cel ten zostal osiagniety przez to, ze znaczna czesc powierzchni pokrywy sklada sie z fald roz¬ chodzacych sie promieniscie do brzegów pokrywy.Ukosna lub stozkowa scianka srodkowa pokrywy najlepiej falista, rowkowana lub faldowana latwo i skutecznie kurczy sie na obrzezu i umozliwia jej powrót do polozenia rozprezonego uszczelniajac pokrywe miedzy scianka pojemnika a kolnierzem uszczelniajacym. Gdy do pokrywy przylozyc sile, której jedna ze skladowych bedzie prostopadla do powierzchni pokrywy, wtedy powierzchnia ta na skutek opisanego uksztaltowania ulegnie elastyczne¬ mu skurczeniu. Pokrywe wystarczy docisnac je- 8186781 3 dynie w jednym miejscu do brzegu pojemnika, aby na zasadzie zatrzasku zamknela szczelnie pojemnik na calym obwodzie.Korzystna jest konstrukcja kolnierza rozszerza¬ jaca sie stozkowo, przy czym jego najwieksza srednica zewnetrzna jest wieksza od srednicy we¬ wnetrznej pojemnika w obrebie jego otworu. Dzie¬ ki temu osiaga sie z jednej strony prowadzenie po rozszerzajacym sie stozku w przypadku nasa¬ dzania pokrywy, a z drugiej strony dokladne u- szczelnienie.Wynalazek jest omówiony szczególowo na podsta¬ wie przykladu wykonania na rysunku, na którym fig 1 przedstawia pokrywe w widoku z góry; fig. 2 — pokrywe w przekroju poprzecznym wzdluz li¬ nii 2—2 na fig. 1, i czesciowy przekrój poprzeczny pojemnika, przedstawiajacy zamkniecie i pojemnik w stanie uszczelnionym; fig. 3 — pokrywe przedsta¬ wiona na fig. 1 i 2 w widoku z dolu; fig. 4 — powiek¬ szony przekrój poprzeczny górnej scianki pojemni¬ ka z pokrywa;, fig. 5 — odmiane wykonania w przekroju poprzecznym jak na fig. 4; fig. 6 — odmia¬ ne wykonania w przekroju poprzecznym; fig. 7 — przekrój poprzeczny pokrywy wzdluz linii 7—7 na fig. 1; fig. 8 — odmiane wykonania pokrywy i pojem¬ nika w przekroju do fig. 2; fig. 9 — pokrywe widoku z dolu przedstawionego na fig. 8; i fig. 10 — frag¬ ment pokrywy i pojemnika w przekroju poprzecz¬ nym w powiekszeniu wg. fig. 8.Wedlug fig. 1—4 pokrywa 10 nasadzana na cy¬ lindryczny pojemnik ze scianka 20, ma kolnierz pokrywy 12 i. powierzchnie pokrywy 14 skladaja¬ cej sie ze srodkowej powierzchni nacisku 16. Po¬ wierzchnia stozkowa lub zbiezna jest najkorzystniej zbudowana z szeregu stojacych scietych fald 18 biegnacych promieniowo od powierzchni nacisku 16 do brzegu pokrywy 12. Faldy te maja górne krawedzie 38 i dolne krawedzie 40 jak na fig. 7.Po zewnetrznej stronie 28 kolnierza uszczelniaja¬ cego 26 na obwodzie brzegu pokrywy 12 znajduje sie wybrzuszenie 21, które po zamknieciu pojem¬ nika wspólpracuje z wybrzuszeniem 34 znajduja¬ cym sie na obwodzie powierzchni wewnetrznej 36 sciany pojemnika. Brzeg pojemnika 12 rozprzestrze¬ nia sie od stozkowo rozszerzajacego sie kolnierza uszczelniajacego 26 do pierscieniowej scianki la¬ czacej 33, której plaszczyzna przebiega równolegle do plaszczyzny powierzchni pokrywy 14. Scianka laczaca 33 graniczy z zalamujaca sie pod katem prostym w dól scianka 37.W wykonaniu przedstawionym na fig. 5 pokry¬ wa 12 na powierzchni górnej nie ma wybrzuszen 21 i 34, a brzeg pokrywy konczy sie scianka la¬ czaca 33.W wykonaniu przedstawionym na fig. 6 znajdu¬ je sie równiez przebiegajaca w dól scianka 37 gra¬ niczaca ze scianka laczaca 33. Scianka ma na swojej wewnetrznej stronie na calym obwodzie wybrzuszenie 35, skierowane do wnetrza pojemni¬ ka.W wykonaniu przedstawionym na fig. 8 —10, na •podniej stronie scianki laczacej 33 i na wewnetrz- 867 4 nej stronie scianki 37 znajduja sie umieszczone w pewnej odleglosci od siebie zeberka 42 zwykle o ksztalcie w przekroju poprzecznym zblizonym do profilu „U". Górna scianka 20 pojemnika opiera sie 5 tu na dowolnych krawedziach zeberek 42, podczas gdy w wykonaniu wg. figur 1 — 4 opiera sie ona na dolnej stronie 27 scianki laczacej 33.Przedstawione na fig. 8 i 10 zebra 42 wystaja ze scianki 26 wzdluz scianki 33, a nastepnie skie- io rowane sa w dól, wzdluz wewnetrznej powierzch¬ ni scianki zewnetrznej 37. Zebra te sa rozstawione na brzegu pokrywy 12 w odpowiednio dobranych odstepach, tak ze podczas nakladania pokrywy 10 powietrze moze latwo wydostawac sie z pojemnika 15 20. Nalezy w szczególnosci zauwazyc, ze wskutek wystawania zeber 42 wzdluz scianki zewnetrznej 37 zapobiega sie powstaniu uszczelnienia miedzy ta ostatnia i pojemnikiem 20 podczas zakladania po¬ krywy. Pozwala to na wyjscie z pojemnika mak- 20 symalnej ilosci powietrza.Jezeli jednak scianka boczna jest stosunkowo ela¬ styczna, skurcz promieniowy gladkiego zamkniecia stozkowego wynosi teoretycznie tylko okolo jednej trzeciej skurczu pokrywy falistej. 25 Te wlasciwosci charakteryzuje równiez fakt, ze odksztalcenia promieniowe lub boczne wzrastaja wraz z wysokoscia rowka i z liczba rowków.Pokrywa wciskana 10 wykonana jest z termo¬ plastycznego tworzywa sztucznego na przyklad z polietylenu niskocisnieniowego ale mozna równiez stosowac polietylen wysokocisnieniowy, polipropy¬ len lub mieszaniny tych lub podobnych tworzyw sztucznych. Pojemnik wykonany jest zwykle z tego samego tworzywa jak i pokrywa. Pokrywe mozna jednak zastosowac równiez do pojemników wykonanych z innych materialów. W celu szczelnego nasadzenia pokrywy 10 na pojemnik, nalezy wy¬ wrzec nacisk na powierzchnie nacisku 16 lub na inny punkt powierzchni górnej pokrywy 14. Po- 40 krywe zdejmuje sie ujmujac ja ponizej brzegu 12, to znaczy w przypadku wykonania pokrywy fig. 1—4 i 8—9 ujmujac za dolna krawedz scian¬ ki 37, zas za scianke laczaca 33 — w wykonaniu wg. fig. 5. 45 PL PLPatent proprietor: Dart Industries Inc., Los Angeles, California (United States of America) Deformable Closure of a Cylindrical Container The invention relates to a deformable spring closure of a cylindrical container which has a sealing collar adjacent the inner wall of the container at the periphery. The invention relates to a closure made of thermoplastic material, intended to be reused in an open-mouth container. Closures for food storage containers, including those made of thermoplastic materials, are known. They generally consist of a cylindrical vessel or of a cup, chalice, cone, etc.-shaped vessel. and a separate closure or cover made of a relatively elastic material. One of them has a peripheral tape which is positioned on the upper edge of the container wall and is pressed over this edge to seal the two parts of the container tightly. The provision of such a closure typically requires the user to apply pressure to the lid at several points in order to successfully seat it on the container. German patent 1225544 relates to a plastic can, the bottom of which is concave due to the shaping of its slanting planes. This bottom is normally firmly attached to the other can. Disconnection is only possible when force is applied from the inside of the can to the bottom, which in the case of a can closed on all sides and with only a small opening is impossible without use of a special tool. Among the other 30 variations are cork-type closures and expansions, which fit loosely into the container opening and which then expand until contact with the inner surface of the container walls. The above closures suffer from a number of drawbacks and are easily warped due to lack of stiffness, and it becomes of course more difficult, sometimes even impossible, to place the warped lid on the container. In closures of the above-mentioned types, the scope of the closure's materials and dimensions, such as wall thickness, diameter, etc., is also limited to a certain extent. The object of the invention is to provide a cylindrical container closure, the snap-on lid of which will have increased flexibility and tightness. This objective is achieved by the fact that a large part of the surface of the cover consists of corrugations radiating to the edges of the cover. A bevelled or conical center wall of the cover preferably wavy, grooved or corrugated easily and effectively shrinks at the periphery and allows it to return to the edge. expanded position, sealing the cover between the container wall and the sealing collar. When a force is applied to the cover, one of its components is perpendicular to the cover surface, then this surface will undergo elastic contraction due to the described shaping. The lid only needs to be pressed against the rim of the container in one place in order to snap the container tightly around its entire circumference. A flange design that extends conically is preferred, with its largest outer diameter greater than the inner diameter of the container within its opening. Thus, on the one hand, a guide along the widening cone is achieved when the cover is fitted, and on the other hand, a perfect seal. The invention is described in detail by means of an embodiment in the drawing, in which Fig. 1 shows the cover in view. in advance; Fig. 2 is a cross-sectional cover taken along line 2-2 in Fig. 1, and a partial cross-sectional view of the container showing the closure and the container in a sealed state; Fig. 3 is a bottom view of the cover shown in Figs. 1 and 2; 4 is an enlarged cross-section of the upper wall of a container with a lid; FIG. 5 is a cross-sectional variant of the embodiment as shown in FIG. 4; 6 shows various embodiments in cross-section; Fig. 7 is a cross-sectional view of the cover along lines 7-7 in Fig. 1; Fig. 8 is a sectional view of Fig. 2, variants of the lid and the container; Fig. 9 is a cover of the bottom view of Fig. 8; and Fig. 10 is a fragment of the cover and the container in an enlarged cross-section according to 8 According to FIGS. 1-4, the lid 10 is attached to a cylindrical wall 20 container, has a lid flange 12 and a lid surface 14 consisting of a central pressure surface 16. The conical or tapering surface is most preferably constructed of a series of upright truncated folds 18 extending radially from the pressure surface 16 to the edge of the lid 12. These folds have upper edges 38 and lower edges 40 as in FIG. 7. On the outside 28 of the sealing collar 26 on the circumference of the edge of the cover 12 there is a bulge 21 which, when the container is closed, cooperates with a bulge 34 provided on the perimeter of the inner surface 36 of the container wall. The edge of the container 12 extends from the conically widening sealing flange 26 to the annular connecting wall 33, the plane of which runs parallel to the plane of the cover surface 14. The connecting wall 33 borders on the wall 37 which breaks down at right angles. 5, the cover 12 has no ridges 21 and 34 on its upper surface, and the edge of the cover ends with a joining wall 33. In the embodiment shown in Fig. 6, there is also a downward wall 37, which borders connecting wall 33. The wall has a bulge 35 on its inside all around its perimeter, facing the interior of the container. In the embodiment shown in Figs. 8-10, on the underside of the connecting wall 33 and on the inside 867 4 on the inside of the wall 37 are spaced apart ribs 42, usually with a cross-sectional shape close to the "U" profile. The top wall 20 of the container here rests on any desired position. the edges of the ribbons 42, while the execution acc. 1 - 4 it rests on the underside 27 of the connecting wall 33. The zebra bars 42 shown in Figs. 8 and 10 protrude from the wall 26 along the wall 33, and then are directed downwards along the inner surface of the outer wall 37 These ribs are spaced at appropriate intervals along the edge of the cover 12, so that when the cover 10 is applied, air can easily escape from the container 15 20. It should be noted in particular that the protrusion of the ribs 42 along the outer wall 37 prevents the formation of a seal between it. the last one and the container 20 when the lid is put on. This allows a maximum amount of air to escape from the container. However, if the sidewall is relatively flexible, the radial contraction of the smooth taper is theoretically only about one third of that of the corrugated lid. 25 These properties are also characterized by the fact that the radial or lateral deformation increases with the height of the groove and the number of grooves. The press-on cover 10 is made of a thermoplastic plastic, for example low-pressure polyethylene, but it is also possible to use high-pressure polyethylene, polypropylene or mixtures of these. or similar plastics. The container is usually made of the same material as the lid. However, the lid can also be used for containers made of other materials. In order to fit the lid 10 tightly onto the container, pressure must be exerted on the pressure surfaces 16 or on another point of the top surface of the cover 14. The cover is removed below the edge 12, that is, in the case of the cover Fig. 1-4. and 8-9 including the lower edge of the wall 37, and the connecting wall 33 - made according to Fig. 5. 45 PL EN
