Abstract

A container with a lid both consisting of plastic material are of oval or similar shape with substantially semi-circular short sides (6) and long sides (8) which are straight or have a large radius of curvature in relation to the radius of curvature of the short sides. The edge portion of the lid has a peripheral edge flange which encloses an edge portion positioned at the mouth of the container and at its surface facing this edge portion has an inwardly directed continuous projection for releasably retaining the lid to the container. The downwardly directed edge flange of the lid is between the short sides and the long sides divided by means of vertical slots (40) for providing edge flange sections (36, 28) at the short sides and the long sides which are separated from each other. Above the inwardly directed projection the edge flange sections of the short sides have a hinge which allows that the projection is at the edge flange sections of the short sides displaced from the retaining position. <IMAGE> <IMAGE>

Description

15 20 25 30 35 40 saa 51 o i i Vid en hink med lock enligt uppfinningen kan locket lätt avtagas genom att kortsidornas kantflänssektioner utan att påverka långsidornas kantflänssektio- ner kan förflyttas ur ingrepp med ingreppsytan på hinkens kantparti. Detta sker företrädesvis genom att de nedanför gångleden belägna kantpartierna av kort- sidornas kantflänssektioner vikes upp till ett stabilt läge, varefter locket kvarhålles vid hinken enbart genom att långsidornas kantflänssektioner med sina utsprång ingriper med den nedåtvända ingreppsytan på hinkens kantparti, vilket ingrepp, då locket skall avlägsnas, lätt övervinnes genom att lång- sidornas kantflänssektioner har rak eller svagt krökt form. 15 20 25 30 35 40 saa 51 o i i In a bucket with lid according to the invention, the lid can be easily removed by moving the edge flange sections of the short sides without affecting the edge flange sections of the long sides without being engaged with the engaging surface on the edge portion of the bucket. This is preferably done by folding the edge portions of the short sides 'edge flange sections below the hinge to a stable position, after which the lid is retained at the bucket only by the long sides' edge flange sections with their projections engaging the downwardly facing engaging surface of the bucket edge portion. removed, easily overcome by the straight or slightly curved shape of the long sides' edge flange sections.

Utformningen av hinken med lock enligt uppfinningen tillåter att locket utformas med sådan förspänning i förhållande till hinkens kantparti, att lockets avtätning av hinken kommer att säkerställas.The design of the bucket with lid according to the invention allows the lid to be designed with such a pretension in relation to the edge portion of the bucket that the sealing of the bucket by the lid will be ensured.

Företrädesvis är långsidornas kantflänssektioner utformade utan någon genom materialförsvagning bildad gångled, vilket ytterligare säkerställer tätheten.Preferably, the edge flange sections of the long sides are formed without any hinge formed by material weakening, which further ensures the tightness.

Vid en föredragen utföringsform av uppfinningen är hinkens flänsparti bildat av ett uppåtriktat väggparti med en fri övre kantyta och en radiellt utåtriktad list, vilken vid sin yttre kant bildar den nedåtvända ingreppsytan på hinkens kantparti. Lämpligen är den radiellt utåtriktade listen vid hinkens lângsidor och är locket vid långsidornas kantflänssektioner försedda med samverkande ingreppsorgan, vilka är belägna ovanför lockets inåtriktade utsprång och den nedåtvända ingreppsytan på hinkens kantparti för att lösbart begränsa utåt- riktad böjning av långsidornas kantflänssektioner till det läge, där det inåt- riktade utsprånget är ur ingrepp med den nedåtvända ingreppsytan. Ingrepps- organen utgöres lämpligen av ett uppåtriktat utsprång på den radiellt utåt- riktade listen och ett nedåtriktat utsprång på lockets kantfläns. Det nedåt- riktade utsprånget på lockets kantfläns kan vara utformat för att vid stapling av flera lock på varandra hinda att locken sammanföres till ett läge, där de är svåra att skilja från varandra.In a preferred embodiment of the invention, the flange portion of the bucket is formed by an upwardly directed wall portion with a free upper edge surface and a radially outwardly directed strip, which at its outer edge forms the downwardly facing engagement surface of the edge portion of the bucket. Suitably, the radially outwardly directed strip at the long sides of the bucket and the lid at the edge flange sections of the long sides are provided with cooperating engaging means, which are located above the inwardly directed projections of the lid and the downwardly facing engagement surface of the bucket edge portion. the inwardly directed projection is out of engagement with the downwardly facing engagement surface. The engaging means suitably consist of an upwardly directed projection on the radially outwardly directed strip and a downwardly directed projection on the edge flange of the lid. The downwardly directed projection on the edge flange of the lid can be designed to prevent the lids from being brought together in a position where they are difficult to separate from each other when stacking several lids on top of each other.

Uppfinningen skall i det följande närmare beskrivas under hänvisning till bifogade ritningar.The invention will be described in more detail below with reference to the accompanying drawings.

Hinken 2 och locket 4 är av oval form med tvâ halvcirkulära kortsidor 4 och två raka långsidor 8.Fig. 5 shows in section stacking of two lids on each other. 10 15 20 25 30 35 40 “I -_-__ ~ so? 51 o in 3 in Figs. 1a and 1b show a bucket 2 with a lid 4. The bucket and the lid consist of plastic material. The bucket 2 and the lid 4 are of oval shape with two semicircular short sides 4 and two straight long sides 8.

Hinken 2 har på konventionellt sätt en botten 10 och en runtomgående sidovägg 12.The bucket 2 has in a conventional manner a bottom 10 and a circumferential side wall 12.

Sidoväggen 12 har ett kantparti 14, vilket är utformat för att tätande ingripa med ett kantparti 16 på locket 4.The side wall 12 has an edge portion 14, which is designed to sealingly engage an edge portion 16 on the lid 4.

Hinkens kantparti 14 utgöres av en övre tätningskant 18 och en på något avstånd under denna anordnad, radiel1t utskjutande list 20, vilken vid sin yttre kant bildar en nedåtvänd ingreppsyta 22. Innanför ingreppsytan 22 har listen 20 ett nedåtriktat, runtomgående väggparti 24, vilket är förbundet med hinkens vägg 12 med hjälp av radiellt inriktade förstärkningsribbor 26. Vid de i sektioni fig.2 visade långsidorna 8 har den radiellt utskjutande listen 20 ett uppåtriktat utsprång 28, medan listen 20 vid de i sektion i fig. 3 visade kortsidorna 6 har plan övre yta.The edge portion 14 of the bucket consists of an upper sealing edge 18 and a radially projecting strip 20 arranged at some distance below it, which at its outer edge forms a downwardly facing engaging surface 22. Inside the engaging surface 22 the strip 20 has a downwardly directed circumferential wall portion 24, which is connected with the wall 12 of the bucket by means of radially aligned reinforcing ribs 26. At the long sides 8 shown in section 2, the radially projecting strip 20 has an upwardly directed projection 28, while the strip 20 at the short sides 6 shown in section in Fig. 3 has a flat upper surface.

Hinkens kantparti 14 omslutes av lockets kantparti 16, vilket bildar en nedåt öppen, runtomgående urtagning 30, vi1ken avgränsas av en inre vägg 32, en övre vägg 34 och en yttre vägg, vilken bi1dar en kantfläns. Vid lockets långsidor 8 har locket en kantfläns 36 medan det vid kortsidorna 6 har en något annorlunda utformad kantfläns 38. Kantflänsarna 36 och 38 är skilda från varandra medelst vertikala slitsar 40 (se fig. la och lb). Slitsarna 40 är vid sina nedre ändar försedda med förseglingsorgan 42, vilka utgöres av lätt brytbara tappar.The edge portion 14 of the bucket is enclosed by the edge portion 16 of the lid, which forms a downwardly open, circumferential recess 30, which is defined by an inner wall 32, an upper wall 34 and an outer wall, which forms an edge flange. At the long sides 8 of the lid the lid has an edge flange 36 while at the short sides 6 it has a slightly differently shaped edge flange 38. The edge flanges 36 and 38 are separated from each other by means of vertical slots 40 (see Figs. 1a and 1b). The slits 40 are provided at their lower ends with sealing means 42, which are constituted by easily breakable pins.

Den övre väggen 34 har vid sin inre yta en centralt belägen, nedåtriktad, runt- omgående list 44, vilken ti1lsammans med väggen 32 avgränsar ett spår, i vilket hinkens tätningskant 18 tätande ingriper.The upper wall 34 has at its inner surface a centrally located, downwardly directed, circumferential strip 44, which together with the wall 32 delimits a groove in which the sealing edge 18 of the bucket engages sealingly.

Lockets 4 kantfläns, vilken således bildar från varandra skilda kantfläns- partier 36 och 38 har ett runtomgående, inåtriktat utsprång 46, vilket griper under den nedåtvända ingreppsytan 22 på listen 20 för att kvarhålla locket vid hinken.The edge flange of the lid 4, which thus forms spaced apart edge flange portions 36 and 38, has a circumferential, inwardly directed projection 46, which engages below the downwardly facing engagement surface 22 of the strip 20 to retain the lid at the bucket.

Kantflänssektionerna 36 vid lockets långsidor 8 är försedda med ett inre, nedåtriktat utsprång 48, vilket ingriper med det uppåtriktade utsprånget 28 på den radiellt utskjutande listen 20. Ingreppet mellan utsprången 28 och 48 åstadkommer förbättrad stabilitet hos de raka kantflänssektionerna 36 och med- för att en viss kraft måste utövas på de raka kantflänssektionerna för att utsprånget 46 skall förflyttas ur ingrepp med ingreppsytan 22.The edge flange sections 36 at the long sides 8 of the lid are provided with an inner, downwardly directed projection 48, which engages with the upwardly directed projection 28 on the radially projecting strip 20. The engagement between the projections 28 and 48 provides improved stability of the straight edge flange sections 36 and some force must be applied to the straight edge flange sections for the projection 46 to be moved out of engagement with the engagement surface 22.

Claims (7)

l0 15 20 30 35 40 sovjgi o q Kantflänspartierna 38 vid lockets halvcirkulära kortsidor har omedelbart ovan- för utsprånget 46 ett inre spår 50, vilket bildar en gångled, som medför att det undre kantpartiet av kantflänsarna 38 kommer att bilda bistabila lås- flänsar 52, vilka är svängbara mellan ett första stabilt läge enligt fig. 3 och ett andra, uppsvängt, stabilt läge enligt fig. 4. I det uppsvängda läget enligt fig. 4 är det inåtriktade utsprånget 46 förflyttat ur ingrepp med ingreppsytan 22, vilket tillåter att locket avlägsnas från hinken genom att de raka kant- flänssektionerna 36 böjes ut från läget, där utsprången 46 ingriper med respek- tive ingreppsyta 22. Då locket skall avlägsnas från hinken förflyttas således först de bistabila låsflänsarna 52 på kantflänssektionerna 38 till det utsvängda läget enligt fig. 4, varvid förseglingsorganen 42 i de vertikala slitsarna 40 mellan kant- flänssektionerna 36 och kantflänssektionerna 38 brytes. Härigenom erhålles en indikation på att hinken varit öppnad även om locket sedan åter anbringas på hinken. Efter uppvikningen av de bistabila låsflänsarna 52 kan locket, såsom nämnts avlägsnas från hinken genom att de raka kantflänssektionerna 36 svänges ut från det läge, där utsprången 46 ingriper med ingreppsytorna 22. Denna ut- svängning av kantflänssektionerna 36 erfordrar normalt ingen annan åtgärd än att man drar loss locket från hinken, vilket får till följd att kantflänssek- tionerna 36 elastiskt fjädrar ut till frigivningsläget. I fig. 5 visas stapling av två lock på varandra, varvid framgår att de nedåt- riktade utsprången 48 på kantflänssektionerna 36 genom ingrepp med den övre ytan av väggen 34 på ett under liggande lock hindrar att locken tryckes samman till ett läge, där de blir svåra att skilja från varandra. Uppfinningen kan modifieras inom ramen för de följande patentkraven. P A T E N T K R A VThe edge flange portions 38 at the semicircular short sides of the lid have an inner groove 50 immediately above the projection 46, which forms a hinge which causes the lower edge portion of the edge flanges 38 to form bistable locking flanges 52, which are pivotable between a first stable position according to Fig. 3 and a second, pivoted, stable position according to Fig. 4. In the pivoted position according to Fig. 4, the inwardly directed projection 46 is moved out of engagement with the engaging surface 22, which allows the lid to be removed from the bucket by bending the straight edge flange sections 36 out of the position, where the projections 46 engage with respective engaging surfaces 22. When the lid is to be removed from the bucket, the bistable locking flanges 52 on the edge flange sections 38 are thus first moved to the flared position according to Fig. 4. wherein the sealing means 42 in the vertical slots 40 between the edge flange sections 36 and the edge flange sections 38 are broken. This gives an indication that the bucket has been opened even if the lid is then reattached to the bucket. After folding up the bistable locking flanges 52, the lid can, as mentioned, be removed from the bucket by pivoting the straight edge flange sections 36 out from the position where the projections 46 engage with the engaging surfaces 22. This pivoting out of the edge flange sections 36 normally requires no action other than pulls the lid off the bucket, which causes the edge flange sections 36 to resiliently spring out to the release position. Fig. 5 shows the stacking of two lids on top of each other, it being seen that the downwardly directed projections 48 on the edge flange sections 36 by engaging the upper surface of the wall 34 on an underlying lid prevent the lids from being compressed to a position where they become difficult to distinguish from each other. The invention can be modified within the scope of the following claims. P A T E N T K R A V 1.
