Description

ASTIANKANSI 72937TANK COVER 72937

Keksintö koskee joustavasti muotoaanmuuttavasta muoviaineesta tehtyä astiankantta, jossa on alaspäin suuntautunut kannenreuna, joka on varustettu sisäpuolena olevalla rengasmaisella joustol.istalla, joka asettuu sisäkkäin kehälistan tai reunalistan kanssa, joka sijaitsee suljettavassa astiassa.The invention relates to a container lid made of a resiliently deformable plastic material, having a downwardly directed lid edge provided with an inner annular resilient strip which nests with a peripheral strip or edge strip located in a closable container.

Tiiviisti suljetuissa astioissa, esimerkiksi maalipurkeissa, käytettävät kansityypit ovat usein vaikeat poistaa, koska tehokas sulkeminen edellyttää astian kansimateriaalin voimakasta esijännittämistä.The types of lids used in hermetically sealed containers, such as paint cans, are often difficult to remove because effective closure requires strong biasing of the container lid material.

Tämän keksinnön tarkoituksena on helpottaa tiiviiden astian-kansien poistamista astioista ja tämä tarkoitus saavutetaan sillä, että taivutettu jousto!istaan liittyvä kannenreuna jatkuu rengasmaisena irroitus reunana, joka kiinnittyy paikoilleen kaksiasentoisesti jouston avulla, ja mainittu irroltusreuna voidaan taivuttaa alaspäin suuntautuneesta asennosta, jossa se voi jännitystilassa olla sisäkkäin / astian reunalistan kanssa, ylöspäinsuuntautuneeseen avattuun asentoon, jossa joustolista on irti astian reunalistasta tai on sen kanssa kosketuksessa vain vähän jännittyneesti.The object of the present invention is to facilitate the removal of tight container lids from containers, and this object is achieved by the bent edge edge associated with the resilient edge continuing as an annular release edge which locks in place in two positions by means of resilience, and said release edge can be bent from a downward position. nested / with the rim of the container, in an upward open position in which the resilient strip is detached from the rim of the container or is in only slight tension with it.

. Kannen reuna ja irroitusreuna muodostavat kaksiasentoisen vlpuliitoksen, sillä mainittujen reunojen väliosa muodostaa kääntyvän liitoksen ja irroitus reunan kehään kohdistuva jännitys toimii jousimaisesti siten, että toisessa asennossa reuna auttaa pitämään mainittua joustolistaa Ja mainittua astian reunallstaa tiukasti toistensa lomassa, ja toisessa asennossa se auttaa pitämään Joustolistaa irti tai vain vähäisessä kosketuksessa mainittuun astian reuna-listaan. Kuljettamalla sormiaan irroitusreunan alapintaa pitkin voi astlankäsittel1jä helposti siirtää reu- 2 72937 naa pois taivutetusta suljetusta asennosta, jossa kehään kohdistuva jännitysvoima on suurimmillaan, ja näin taivuttaa ir-roitusreunan avattuun asentoon. Nyt kansi voidaan helposti poistaa, ja astian ollessa käytössä voidaan kansi asettaa löysästi paikoilleen suojaamaan sisältöä tilapäisesti.. The edge of the lid and the release edge form a two-position intermediate connection, since the intermediate part of said edges forms a pivotable connection and the tension on the circumference of the release edge acts springily so that in one position the edge helps to hold said elastic strip only in slight contact with said container edge strip. By moving its fingers along the lower surface of the release edge, the spindle handler can easily move the edge away from the bent closed position where the tensile force on the circumference is at its maximum, thus bending the release edge to the open position. Now the lid can be easily removed, and when the container is in use, the lid can be placed loosely in place to temporarily protect the contents.

Tämän keksinnönmukaisen kannen eräälle toteutustavalle on tunnusomaista se, että kannen reunan sisäpinta on varustettu rengasmaisella uralla, joka laajenee kartlomaisesti alaspäin mainitussa kannen reunassa juuri joustollstan yläpuolella olevaa ohutta taivutettavissa olevaa kohtaa kohti. Tämä toteutustapa on erityisen sopiva aksiaalisesti jännittyneiden kansien ollessa kyseessä, sillä tällöin kannen alapinta asettuu tiiviisti vastakkain kannen suun reunan kanssa kapeaa sulkuviivaa pitkin, koska kannen taivutettu reuna on radiaallsesti astian suun ulkopuolella ja jatkuu kannen pinnaksi voimakkaan taipeen kautta niin, ettei mitään taivutus-momenttia pääse välittymään. Kuvatuntyyppinen kansi on aksiaalisesti jännittynyt, sillä astian suun reunan ja astian reunalistan alasivun tai sulkulistan välinen etäisyys on suurempi kuin kannen sulkuviivan ja mainitun avatussa asennossa olevan kannen reunan joustollstan yläpuolen välinen vertikaalinen etäisyys. Kun kansi asetetaan astian päälle, aiheutuu kannen reunaan voimakas aksiaalinen jännitysvoima, ja jännitys on sitä suurempi mitä suurempi on tarvittava paine pinta-yksikköä kohti astian suun Ja kannen välisellä sulkuviivalla. Koska kannen reuna on vain aksiaalisesti Jännittynyt ja siis vain vetovoiman alaisena, voi kannen reunan ja irroi-tusreunan välissä oleva liitos olla suhteellisen ohutseinäinen, ja irroitusreunan taivuttaminen yhdestä asennosta toiseen vaatii käytännössä vain irroitusreunan maksimaalisen kehälle kohdistuvan venytysvoiman voittamisen.An embodiment of the lid according to the invention is characterized in that the inner surface of the edge of the lid is provided with an annular groove which extends cartilage-like downwards at said edge of the lid towards a thin bendable point just above the elastic. This embodiment is particularly suitable for axially tensioned lids, since the lower surface of the lid is tightly opposite the edge of the lid mouth along a narrow closure line, as the bent edge of the lid is radially outside the mouth of the container and extends to the lid surface through a strong bend be transmitted. The described type of cover is axially tense, since the distance between the mouth of the container edge and the container or the underside of the edge strip of the revocation list is larger than the lid seal line and the vertical distance between said open position of the lid rim joustollstan upper side. When the lid is placed on top of the container, a strong axial tension is exerted on the edge of the lid, and the greater the required pressure per unit area per line of the container between the mouth and the lid, the greater the tension. Since the edge of the cover is only axially tensioned and thus only under tension, the joint between the edge of the cover and the release edge can be relatively thin-walled, and bending the release edge from one position to practice requires only overcoming the maximum circumferential stretching force of the release edge.

Jos astlankannet aiotaan sulkea tiukasti vain aksiaalisen vetovoiman avulla, on vähemmän tärkeätä, onko kehälle koh-If the lid covers are to be closed tightly only by axial traction, it is less important whether the circumference is

Muun tyyppiset astiat, kuten marmelaadiastiat tms., joissa on ulospäin pullottavat sivuseinät astian suu-reunan alapuolella, voidaan varustaa sellaisilla irroitusreu-noi.lla, joiden halkaisija on mainitun reunan sul.kuasennossa suurempi kuin avatussa asennossa, ja tällöin mainitun reunan kehälle kohdistuva venytysvoima on suurempi suljetussa asennossa, ja tämä onkin erittäin tärkeätä niiden kansityypplen kohdalla, joissa astian suullstan ja astian kannen välinen tiivis sulkeutuminen perustuu radiaallseen esijännitykseen.3 72937 extending tensile force at its maximum in the closed position or in the open position, and for this reason the release edge can be directed practically perpendicularly downwards in order to avoid as few problems as possible when placing the containers side by side. Other types of containers, such as marmalade containers or the like, which have outwardly bottling side walls below the mouth edge of the container, may be provided with release edges having a larger diameter in the closed position of said edge than in the open position, in which case the tensile force on said edge is circumferential. larger in the closed position, and this is very important for those types of lids where the tight closure between the mouth of the container and the lid of the container is based on radial prestressing.

Keksinnönmukaiselle kannelle on ominaista patenttivaatimuksen 1 tunnusmerkkiosassa mainitut seikat.The cover according to the invention is characterized by the features mentioned in the characterizing part of claim 1.

Seuraavassa keksintöä valaistaan tarkemmin viittaamalla oheisiin piirustuksiin, joissa: kuvio 1 esittää radiaalista polkklleikkauskuvaa kekslnnönmu-kaisesta kannesta, kuvio 2 esittää mainittua kantta päältä katsottuna, kuvio 3 esittää poikkileikkauskuvaa edullisesta keksinnönmu-kaisen kannen toteutusmuodosta.In the following, the invention will be further illustrated with reference to the accompanying drawings, in which: Fig. 1 shows a radial pedal sectional view of a lid according to the invention, Fig. 2 shows a top view of said lid, Fig. 3 shows a cross-sectional view of a preferred embodiment of the lid.

Kuvioissa 1-3 esitetyssä astlankannessa on tasopinta 1 ja käytännöllisesti katsoen aksiaalinen ja käytössä ollessa alaspäinsuuntautunut taivutettu reuna 2, joka kartiomaisen reunaosan 3 kautta yhtyy radiaallseen reunaosaan 4, joka liittyy kannen tasopintaan 1 käytännöllisesti katsoen aksiaalisen sisemmän taivutetun reunan 5 kautta. Radiaalisen reunaosan 4 alapinta on varustettu aksiaalisella ohjaus- « 72937 reunalla 6 ja terävällä sulkulistalla 7, joka asettuu vastakkain astian suun reunan kanssa kapeaa sulkuviivaa pitkin. Kun astia on tiiviisti suljettu, asettuu kannen reunan 2 sisäpuolella oleva joustolista 6 sisäkkäin alas-päinsuuntautuvan lukklutumlsreunan kanssa, joka sijaitsee astian seinästä 10 ulkonevan reunallstan 9 päässä. Kuvassa 3 on katkoviivoilla esitetty kartlomainen reunaosa 3 siinä asennossa, Jossa kansi on löysästi paikoillaan astian päällä. Tässä asennossa on astian suun reunan ja alaspäln-suuntautuneen säiliön reunallstan 9 sulkureunan välinen pystyetäisyys suurempi kuin sulkulistan 7 ja joustolistan 8 yläpuolen välinen pystyetäisyys. Kun kansi asetetaan tiukasti paikoilleen astian päälle, kartiomaineu reunaosa 3 painetaan alas - esitetty yhtenäisillä viivoilla - aksiaa-lisesti painaen niin, että joustolista 8 asettuu sisäkkäin astian reunallstan 9 lukkiutumisreunan kanssa. Kannen reunaan 2 kohdistuu näin aksiaalinen venyttävä voima, jonka ansiosta sulkulista 7 painuu voimakkaasti astian suuta vasten.The table lid shown in Figs. The lower surface of the radial edge portion 4 is provided with an axial guide edge 72 and a sharp closure strip 7 opposed to the mouth edge of the container along a narrow closure line. When the container is tightly closed, a resilient strip 6 inside the edge 2 of the lid is nested with a downwardly directed locking edge located at the end of the edge 9 projecting from the wall 10 of the container. Figure 3 shows, in broken lines, the cartilaginous edge part 3 in the position in which the lid is loosely in place on the container. In this position, the container mouth the vertical distance between the edge and the alaspäln-oriented container closure edge 9 reunallstan greater than the CRL 7 and the vertical distance between the upper side of the flexible rail 8. When the lid is firmly placed on the container, the conical edge portion 3 is pressed down - shown in solid lines - axially by pressing so that the resilient strip 8 is nested with the locking edge of the container edge 9. The edge 2 of the lid is thus subjected to an axial stretching force, as a result of which the closing strip 7 presses strongly against the mouth of the container.

Välittömästi Joustolistan 8 yläpuolella on kannen reuna 2 varustettu rengasmaisella uralla 11, joka ulottuu ohutseinäisen osan 12 kautta irroitusreunaan 13, Joka suljetussa asennossa suuntautuu alaspäin, kuten kuvassa on esitetty.Immediately above the resilient strip 8, the edge 2 of the cover is provided with an annular groove 11 extending through the thin-walled part 12 to the release edge 13, which in the closed position faces downwards, as shown in the figure.

Kun astian käyttäjä haluaa poistaa kannen, hän kuljettaa sormiaan lrroitusreunan 13 alapintaa pitkin ja kohdistaa siihen ulospäinsuuntautuvan paineen nostaen kehän jännityksen niin suureksi, että reuna napsahtaa yhtäkkiä ylöspäin katkoviivoilla osoitettuun yläasentoonsa, jossa Joustolista 8 on irti astian reunalistasta 9· Näin ollen irroitusreuna 13 toimii kaksiasentoisena vipuliitoksena ohutseinäisen osan 12 kohdasta, joka liittyy kääntyvästi kannen reunaan 2 ja pysyy 5 72937 ääriasennoissaan reunan kehään kohdistuvan venytysvoiman ansiosta. Jos irroitusreuna 13 on muodoltaan sellainen, että se suljetussa asennossa ulottuu kauemmaksi astian seinästä radiaalisessa suunnassa, kehälle kohdistuva lisääntynyt vetovoima saa aikaan joustolistan 8 ja astian reunalistan vieläkin kiinteämmän yhteenliittymisen.When the user of the container wants to remove the lid, he runs his fingers along the lower surface of the release edge 13 and applies outward pressure to increase the circumferential tension so that the edge suddenly snaps up to its upper position indicated by the dashed from a point in the thin-walled part 12 which pivotally joins the edge 2 of the cover and remains in its extreme positions 5 72937 due to the tensile force acting on the circumference of the edge. If the release edge 13 is shaped in such a way that in the closed position it extends farther from the wall of the container in the radial direction, the increased traction on the circumference results in an even tighter connection of the resilient strip 8 and the container edge strip.

Ei ole aivan välttämätöntä ottaa sulkulistaa täysin erilleen astian reunalistasta 9 kuvion 3 esittämässä toteutustavassa, kun kansi otetaan pois tai asetetaan astiaan paikoilleen. Keksinnönmukainen astiankansi, jossa on kaksiasentoinen jouston avulla kiinnittyvä reuna, voidaan muotoilla eri tavoin, kuin piirroksessa on esitetty. Varsinkin kannen kehä voi olla säännöllinen monikulmio, jossa on pyöristetyt nurkat, jotta se sopii vastaaviin monikulmaisiin astioihin, kuten ruuansäilytysastioihin, lounasrasioihin, ruokapurk-keihin tms.It is not absolutely necessary to completely separate the closure strip from the edge strip 9 of the container in the embodiment shown in Fig. 3 when the lid is removed or placed in the container. The container lid according to the invention, which has a two-position resilient edge, can be shaped in different ways than shown in the drawing. In particular, the perimeter of the lid may be a regular polygon with rounded corners to fit corresponding polygonal containers, such as food containers, lunch boxes, food jars and the like.
