Description

Oblasť technikyTechnical field

Predkladané technické riešenie satýka uzáveru nanádobusjednoduchýmotváranímThe presented technical solution of the cap closure by simple simple opening

Technické riešenie spočíva v uzávere na nádobu, ktorá sa zvyčajne označuje ako ľahko otvárateľná a ktorá je určená na uskladnenie akéhokoľvek typu baleného jedla a je tvorená kov ovýmtelo m, najmä valcovitého tvaru, pričom uzáver je pôvodne súčasťou nádoby a jeho otvorenie sa uskutočňuje potiahnutím uška umiestneného náhornej strane uvedeného uzáveru a pripevneného k nemu prostredníctvomnitu.The technical solution consists in a closure for a container, which is usually referred to as easy to open and which is intended for storing any type of packaged food and consists of a metal body, in particular cylindrical, the closure being originally part of the container and its opening being on the upper side of said closure and attached thereto by means of a thread.

Doterajší stav technikyPrior art

Známe sú nádoby, ktoré sa bežne označujú ako plechovky, vybavené systémomjednoduchého otvárania. Tieto systémy s jednoduchým otváraním zvyčajne pozostávajú z uzáveru pripevniteľného k nádobe oddeliteľným spôsobom, a to vďaka rezacej čiare predpokladanej na jeho oslabenie, ktorý má ďalej na svojej hornej strane uško na ťahanie umožňujúce uhlové oddelenie uzáveru, čím sa odhalí aspoň časť obsahu nádoby.Containers, commonly referred to as cans, are known to be equipped with a simple opening system. These easy-open systems usually consist of a closure attachable to the container in a detachable manner, thanks to a cutting line intended to weaken it, which further has a pull tab on its upper side allowing angular separation of the closure, thereby revealing at least part of the contents.

Tieto známe plechovky majú určité nevýhody spojené so samotným systémom otvárania. Na jednej strane znamená najprv potreba potiahnuť uško isté vynaloženie sily na čiastočné oddelenie uška od povrchu uzáveru a následne vyvinutie ťahovej sily smerom nahor na uško, čo umožní potiahnuť spolu s ním samotný uzáver s cieľom oddeliť ho od tela nádoby.These known cans have certain disadvantages associated with the opening system itself. On the one hand, the need to first pull the lug with some force to partially separate the lug from the surface of the closure and then to exert an upward pulling force on the lug, which allows the closure itself to be pulled together to separate it from the container body.

Pokiaľ ide o prvý bod, na vykonanie tejto činnosti je často potrebné použiť nejaký nástroj, pretože môže byť ťažké oddeliť uško od uzáveru vzhľadom na skutočnosť, že k takémuto zdvihnutiu dochádza nielen prostredníctvom vyvinutia pákovej sily voči nitu, ktorý uško upevňuje k uzáveru, ale aj voči samotnému telu plechovky. Táto pôsobiaca sila často spôsobí, že sa uško úplne odpojí od nitu, čím sa znemožní otvorenie nádoby.As for the first point, it is often necessary to use a tool to perform this operation, as it can be difficult to separate the lug from the closure due to the fact that such lifting occurs not only by developing leverage against the thread that secures the lug to the closure but also against the body of the can itself. This force often causes the lug to disengage completely from the thread, making it impossible to open the container.

Pokiaľ ide o ťahovú silu smerom nahor vyvíjanú na uško, záleží nielen na odpore rezovej čiary po obvode oblasti pripojenia uzáveru k nádobe, ale aj na konštrukcii samotného nitu, pretože otváranie veka je zvyčajne uľahčované pákovou silou, ktorú jeden koniec uška v oblasti nitu vytvára voči telu plechovky, čím sa obmedzuje uhol, pod ktorým sauško ťahá, približne na 22°.As for the upward tensile force exerted on the lug, it depends not only on the resistance of the cutting line around the circumference of the area of attachment of the closure to the container but also on the construction of the thread itself, as the lid opening is usually facilitated by a lever force generated by one end of the lug in the thread area. the body of the can, thereby limiting the angle at which the bag is pulled to approximately 22 °.

Podstata technického riešeniaThe essence of the technical solution

Predkladané technické riešenie rieši uvedené nevýhody už známy ch plechoviek a ponúka uzáver pre nádoby, ktoré sú zvyčajne označované ako ľahko otvárateľné a navrhnuté tak, aby uchovávali akýkoľvek typ baleného jedla. Podstata spočíva v špeciálnom vyhotovení nitu, ktorým sa uško na ťahanie pripája k telu uzávera a ktorý umožňuje ľahké otvorenie s väčším uhlom zdvihu uška bez rizika jeho odpojenia.The present technical solution solves the mentioned disadvantages of already known cans and offers a closure for containers, which are usually referred to as easy to open and designed to store any type of packaged food. The essence lies in the special design of the thread, which connects the lug to the body of the closure and which allows easy opening with a larger angle of stroke of the lug without the risk of disconnecting it.

Ako bolo spomenuté, nádoba je tvorená kovovým telom, najmä valcovitého tvaru, a uzáver je pôvodne súčasťou nádoby a otvára sapotiahnutím uška umiestneného na hornej strane uvedeného uzáveru a pripevné néhok nemu prostredníctvomnitu.As mentioned, the container is formed by a metal body, in particular of cylindrical shape, and the closure is originally part of the container and opens by pulling the tab located on top of said closure and attached to it by means of a thread.

Uzáver podľa predkladaného technického riešenia je teda typu, v ktorom je uško na ťahanie pripevnené k telu uzáveru kovovej nádoby prostredníctvom nitu. Toto uško na ťahanie má na svojom najširšom konci v podstate zaoblený klinovitý tvar a na protiľahlom konci lichobežníkový tvar a týmto lichobežníkovým koncom je spojené s telom uzáverom pomocou nitu.The closure according to the present technical solution is thus of the type in which the pull tab is attached to the closure body of the metal container by means of a rivet. This pull tab has a substantially rounded wedge-shaped shape at its widest end and a trapezoidal shape at the opposite end, and is connected to this closure body by a rivet with this trapezoidal end.

Na tomto lichobežníkovom konci má uško tiež lichobežníkové prehĺbenie, ktoré má oslabenú líniu v tvare U, ktorá čiastočne lemuje obvod kruhového nitu. Na tomto konci má ďalej uško v podstate trojuholníkové predĺženie, ktorého vrchol definuje oporný bod uška voči telu uzáveru pri otváraní.At this trapezoidal end, the lug also has a trapezoidal depression which has a weakened U-shaped line which partially lines the circumference of the circular thread. At this end, the lug further has a substantially triangular extension, the apex of which defines the point of support of the lug with respect to the closure body when opened.

Predkladaný návrh zostavy uška a nitu uzáveru podľa tohto technického riešenia umožňuje otvorenie pod uhlom 29°, teda podstatne väčším, ako je ten, ktorý poskytujú uzávery s jednoduchým otváranímpodľa doterajšieho stavu techniky, čím sauľahčí otvorenie nádoby a predíde vyššie uvedenýmnepríjemnostiamThe present design of the closure lug and thread assembly according to this technical solution allows opening at an angle of 29 °, i.e. substantially larger than that provided by the closures with simple opening according to the prior art, thus facilitating the opening of the container and avoiding the above-mentioned inconveniences.

Príklady uskutočneniaExamples of embodiments

Ako je znázornené na obrázku 1, uzáver podľa predkladaného technického riešenia je typu, v ktorom je uško 2 naťahanie pripevnené k telu 1 uzáveru kovovej nádoby prostredníctvomokrúhleho nitu 3.As shown in Figure 1, the closure according to the present technical solution is of the type in which the pull tab 2 is attached to the closure body 1 of the metal container by means of a round thread 3.

Pri pohľade na obrázky 1 a 2 má toto uško 2 na ťahanie na svojom najširšom konci v podstate zaoblený klinovitý tvar a na protiľahlom konci lichobežníkový tvar a týmto lichobežníkovým koncom je spojený s telom 1 uzáveru pomocou nitu 3.Referring to Figures 1 and 2, this pull tab 2 has a substantially rounded wedge-shaped shape at its widest end and a trapezoidal shape at the opposite end, and is connected to this closure body 1 by a rivet 3 by means of a rivet 3.

Na tomto lichobežníkovom konci má uško 2 tiež lichobežníkové prehĺbenie, ktoré obsahuje oslabenú líniu 4 v tvare U, ktorá čiastočne lemuje obvod nitu 3. Na tomto konci má ďalej uško 2 v podstate trojuholníkové predĺženie 5, ktorého vrchol definuje oporný bod uška 2 voči telu 1 uzáveru pri otváraní.At this trapezoidal end, the lug 2 also has a trapezoidal depression, which comprises a weakened U-shaped line 4, which partially lines the circumference of the thread 3. At this end, the lug 2 further has a substantially triangular extension 5, the apex of which defines the support point of the lug 2 relative to the body 1. shutter when opening.

Pri používaní počas zdvíhania uška 2 a oddeľovania tela 1 uzáveru umožňuje spolupráca oslabenej línie 4, predĺženia 5 a nitu 3 otvorenie uzáveru.In use during the lifting of the lug 2 and the separation of the body 1 of the closure, the cooperation of the weakened line 4, the extension 5 and the thread 3 allows the closure to be opened.

Ako je vidieť na obrázkoch 3a a 3b, uhol otvorenia uška 2 je určený priemerom A nitu 3 a vzdialenosťou Bod bodu 10, kde končí oslabená línia 4, až po špičku uška 2, čo je oblasť, ktorá pôsobí silou na uvedenú oslabenú líniu 4, aby roztrhla kov. Keď sa potom na uško 2 na ťahanie vyvinie sila smeromhore, stredná oblasť C medzi nitom 3a špičkou uška 2 sa deformuje vďaka oslabenej línn 4 a geometrii zostavy.As can be seen in Figures 3a and 3b, the opening angle of the lug 2 is determined by the diameter A of the rivet 3 and the distance from the point of point 10 where the weakened line 4 ends up to the tip of the lug 2, which is the area acting on the weakened line 4. to tear the metal. When an upward force is then applied to the pulling lug 2, the central region C between the yarn 3a and the tip of the lug 2 is deformed due to the weakened line 4 and the geometry of the assembly.

Na obrázku 3b je vidieť, že uhol tvorený telom 1 uzáveru a zdvihnutým uškom 2 je pri konvenčnom uzávere 22°.It can be seen in Figure 3b that the angle formed by the closure body 1 and the raised lug 2 is 22 ° in a conventional closure.

Uzáver podľa technického riešenia a najmä zostava uška 2 a nitu 3 umožňujú väčšie otvorenie konvenčného uzáveru, napríklad pod uhlom 29° v porovnaní s uhlom 22° konvenčného uzáveru, čím sa uľahčí otvorenie nádoby a zníži sa sila potrebná na otvorenie.The closure according to the technical solution and in particular the lug assembly 2 and the thread 3 allow a larger opening of the conventional closure, for example at an angle of 29 ° compared to an angle of 22 ° of the conventional closure, thus facilitating the opening of the container and reducing the force required for opening.

Na tento účel je v uzávere podľa technického riešenia vzdialenosť B'od bodu 10, kde končí oslabená linia 4 k špičke uška 2 zmenšená a má dĺžku B'< B, takže B' = 0,66 B.For this purpose, in the closure according to the technical solution, the distance B 'from point 10, where the weakened line 4 to the tip of the lug 2 ends, is reduced and has a length B' <B, so that B '= 0.66 B.

Ako je znázornené na obrázkoch 4a a 4b, vzhľadom na dĺžku L uška 2 uzáveru podľa technického riešenia vzdialenosť B' medzi koncom oslabenej línie 4 a špičkou uška 2 je B' = L/13,5.As shown in Figures 4a and 4b, with respect to the length L of the closure lug 2 according to the invention, the distance B 'between the end of the weakened line 4 and the tip of the lug 2 is B' = L / 13.5.

Vo výhodnomuskutočneníje táto vzdialenosť B' rovná 2,75 mm.In a preferred embodiment, this distance B 'is equal to 2.75 mm.

Na dosiahnutie tejto väčšej vzdialenosti B' sa napríklad v príkladnom uskutočnení zväčší priemer A nitu 3.To achieve this greater distance B ', for example, in the exemplary embodiment, the diameter A of the thread 3 is increased.

Uzáver podľa predkladaného technického riešenia navyše v súlade s hlavne trojuholníkovým predĺžením 5, ktorého vrchol definuje oporný bod uška 2 voči telu 1 uzáveru, disponuje konkávnym prehĺbením 6, ktoré uľahčuje otáčanie konca uška 2 na tele 1 uzáveru, aby sa ešte viac uľahčilo otváranie. Vo výhodnom uskutočnení má prehĺbenie 6 polomer 0,7 mm.In addition, in accordance with the mainly triangular extension 5, the apex of which defines the point of support of the lug 2 relative to the closure body 1, the closure according to the present technical solution has a concave recess 6 which facilitates rotation of the lug end 2 on the closure body 1 to further facilitate opening. In a preferred embodiment, the recess 6 has a radius of 0.7 mm.

Rovnako na uľahčenie otvárania zviera zaoblený koniec uška 2 na ťahanie protiľahlý k oblasti nitu 3 uhol 174° s rovinou povrchu tela 1 uzáveru, čo umožňuje rýchlejšie dosiahnutie uhla 29° na hornom konci uška 2.Also, to facilitate the opening of the animal, the rounded end of the pulling lug 2 opposite the region of the rivet 3 is at an angle of 174 ° to the plane of the surface of the closure body 1, allowing a faster angle of 29 ° at the upper end of the lug 2.
