Definitions

• TITLE Tin can with liquid drain opening
• the invention relates to a tin can.
• a tin can comprising a tubular body having two opposite ends closed respectively by a lower lid and an upper lid.
• the upper lid has a removable upper part delimited by an upper line of incipient rupture and equipped with an upper opening member, thus forming a so-called easy opening system or " EOE” for “Easy Open End”.
• the removable upper part has an area at least greater than 90% of an area of the upper cover to be able to empty the can of all of its foodstuffs; one speaks classically of an integral opening on the upper cover.
• the invention proposes an easy, fast and economical solution for separating the foodstuffs from the juice, in other words purging the solid content from the liquid content, with the metal can, and without using an external device.
• the invention proposes a tin can comprising a tubular body having two opposite ends closed respectively by a lower lid and an upper lid, in which the upper lid has a removable upper part delimited by an upper line of incipient rupture and equipped with an upper opening member, this removable upper part having an area at least greater than 90% of an area of the upper cover in order to be able to empty the can of foodstuffs, said tin can being remarkable in that the lower lid has a removable lower part delimited by a lower line of incipient rupture and equipped with a lower opening member, such a removable lower part having at least one slender main section having a width of value less than or equal to 3 millimeters and a length of value greater than or equal to 10 millimeters, in order to be able to empty the can of a liquid juice before emptying it of foodstuffs.
• the invention therefore proposes to purge the foodstuffs of the liquid juice through a lower opening defined by the removable lower part which, once opened, has at least such an elongated main section.
• this lower opening will form a lower drain opening serving to empty the liquid juice, without letting the foodstuffs leak out, and this thanks to the thin and oblong shape, longer than wide, of the slender main section.
• Its thinness width less than or equal to 3 mm
• its length ensures that foodstuffs do not come block the lower drain opening while providing an increased drain area to quickly drain the liquid juice.
• the slender main section is straight or curved.
• the length of the elongated main section has a value of between 10 and 50 millimeters.
• the width of the longilinear main section has a value of between 1 and 2 millimeters.
• the removable lower part has at least one elongated secondary section, connected to the elongated main section and extending transversely with respect to the elongated main section, where said elongated secondary section has a width of less or equal to 2 millimeters and a length of value greater than or equal to 5 millimeters.
• the lower drain opening has two or more elongated and thin sections which intersect, thus increasing the draining surface, while preventing foodstuffs from escaping because these longer slender sections are all thin (lower width or equal to 3 mm).
• the longilinear secondary section is rectilinear or curved.
• the elongated main section and the elongated secondary section together define an "X", "T", “L”, “Y” or "V" shape.
• the lower drain opening will have an "X”, "T”, “L”, “Y” or "V" shape.
• the lower drain opening may have a more complex shape, for example "E”, “H”, “W”, “F”, “Z”, etc.
• the length of the longilinear secondary section has a value of between 5 and 30 millimeters.
• the width of the elongated secondary section has a value of between 1 and 2 millimeters.
• the lower opening member comprises, on either side of a central part fixed to the removable lower part, a gripping tongue and a support beak adapted to cause a break in the line lower incipient fracture at one end of the slender main section.
• a user grabs hold of the grip tab to move it away from the removable lower part, so that the lower opening member forms a lever which causes the support beak to cause a local break in the lower line initiator of rupture, at this end of the slender main section, and finally the user pulls on the lower opening member so as to continue the tearing of the lower line of initiator of rupture and to separate all or part of the removable lower part from the lower cover, thus forming the lower drain opening.
• the invention also relates to a method for opening a tin can according to the invention, such a tin can receiving internally foodstuffs bathed in a liquid juice, this opening method implementing the following steps :
• FIG 1 is a schematic perspective view from above of a tin can according to the invention, showing its upper cover, the removable upper part of which is closed;
• FIG 2 is a schematic perspective view from below of the can of Figure 1, showing its lower cover, the removable lower part of which is closed;
• FIG 3 is a schematic perspective view from below of the can of Figures 1 and 2, showing the removable lower part of the lower cover, with its lower opening member, at the start of the opening of this removable lower part in order to begin clearing the lower drain opening;
• FIG 4 is a schematic perspective view from below of the can of Figures 1 to 3, at the near end of the opening of the removable lower part in order to release almost completely the lower drain opening, where this Figure 4 shows a zoom on the removable lower part;
• FIG 5 is a schematic perspective view from above of the can of Figures 1 to 4, allowing to visualize the partial opening of the removable upper part of the upper cover, in order to create an air intake consecutively to the opening of the removable lower part illustrated in Figures 3 and 4;
• FIG 6 is a schematic perspective view from below of the can of Figures 1 to 5, allowing to visualize the draining of the liquid juice through the lower drain opening;
• FIG 7 is a schematic perspective view from above of the can of Figures 1 to 4, allowing to visualize the complete opening of the removable upper part of the upper lid, in order to recover the foodstuffs after the draining of the juice liquid shown in Figure 6;
• FIG 8 is a schematic top view of the can of Figures 1 to 7, with the removable upper part closed;
• FIG 9 is a schematic bottom view of the can of Figures 1 to 8, with the removable lower part closed, and with a zoom on this removable lower part;
• FIG 10 is a schematic view of three alternative embodiments of the removable lower part, having other shapes than that illustrated in Figure 9.
• a can according to an exemplary embodiment of the invention, comprises a metallic tubular body 10 having two opposite ends closed respectively by a lower lid 4 and an upper lid 3.
• the top cover 3 is of the cover type with full opening, and it has:
• central closing panel 31 comprising a removable upper part 32 delimited by an upper line of rupture initiation 33 and equipped with an upper opening member 34.
• This removable upper part 32 has an area at least greater than 90% of an area of the upper cover 3 in order to be able to empty the can 1 of foodstuffs DA (as visible in FIG. 7).
• the upper opening member 34 is for example of the “opening ring” type, and it comprises, on either side of a central part fixed to the removable upper part 32, a grip tab 37 and a support nose 38 adapted to cause a break in the upper line of incipient fracture 33.
• the user maneuvers the upper opening member 34 to partially tear the upper line of initiating rupture 33, then he pulls on this upper opening member 34 to continue the tearing of the upper line of incipient rupture 33 and thus open the removable upper part 32 sufficiently to empty the tin can 1 of foodstuffs DA, or even completely dissociate the removable upper part 32 from the upper lid 3.
• the lower cover 4 presents:
• central closing panel 41 comprising a removable lower part 42 (not visible in Figure 2) delimited by a lower line of rupture initiation 43 and equipped with a lower opening member 44.
• this removable lower part 42 has an elongated main section 45 having a width G1 of value less than or equal to 3 millimeters, and for example a value between 1 and 2 millimeters, and a length L1 of greater value or equal to 10 millimeters, and for example a value between 10 and 50 millimeters.
• the lower opening member 44 is for example of the “opening ring” type, and it comprises, on either side of a central part fixed to the removable lower part 42, a grip tab 47 and a bearing nose 48 adapted to cause a break in the lower line of incipient fracture 43 at the level of one end of the elongated main section 45.
• the user maneuvers the lower opening member 44 to partially tear the lower line of incipient rupture 43 at the level of the end of the slender main section 45, then he pulls on this lower opening member 44 to continue tearing the lower line of incipient rupture 43 and thus open the removable lower part 42 sufficiently to form in the lower cover 4 a lower drain opening 49, in order to be able to drain the can 1 of a liquid juice JU before emptying it of the foodstuffs DA.
• This lower drain opening 49 is thus delimited by the lower line of rupture initiation 43.
• this removable lower part 42 also has a slender secondary section 46, connected to the slender main section 45 and extending transversely vis-à-vis the slender main section 45 , where such an elongated secondary section 46 has a width G2 with a value less than or equal to 2 millimeters, and for example a value between 1 and 2 millimeters, and a length L2 with a value greater than or equal to 5 millimeters, and for example a value between 5 and 30 millimeters.
• the slender secondary section 46 crosses the slender main section 45 in the middle at one of its ends, so that the slender main section 45 and the slender secondary section 46 together define a " T”.
• the lower drain opening 49 has a general “T” shape.
