Description

Technical Field

[0001] The present invention relates to an integrated device for opening and closing cans and tins with non-deformable partial lids, the partial lids being used to cover the pouring orifice in the container, opening the pouring orifice in the container by separating a portion of its initial lid to allow partial emptying of its contents.

[0002] By way of example, the requirements for covering the orifice to store product residues due to partial evacuation have previously arisen from the following: gradual consumption of products in metal or plastic containers (such as condensed milk and sweetened dairy products) related to food consumption (excluding boiling, volatile, caustic, corrosive, or viscous liquids); carbonated energy drinks; products not necessarily related to food consumption, such as pharmaceuticals or cosmetic products; products designated for industrial or household cleaning; the supply of lubricating fluids for vehicle engines or stationary machinery; and the care of street furniture, etc.

[0003] The integrated device for opening and closing cans and tin cans with non-deformable partial lids, which is the object of the present invention, can be used in particular to cover the pouring orifice of the container and allow its contents to be partially emptied by pouring, especially for cans with a circular base. Background Technology

[0004] To date, only known closing devices utilize thread shutters or apply pressure to a component covering the entire diameter of the surface of the can or tin can's open end. Typically, a circular sheet of semi-soft plastic material is used, with its annular side externally superimposed on the sidewall of the can or tin can or threaded tin lid. This is also often the solution when a partial opening / closing device for opening the can or tin can is required.

[0005] Examples of products whose packaging (wrapping) opens fully or partially on one side as a pouring hole are, as previously mentioned, condensed milk in aluminum cans and soft drinks. At least the first type involves a lid for sealing, although not in all countries where they are marketed. However, in the industry that supplies soft drinks in aluminum cans with partial openings in their lids, the addition of lids to them on the production side is generally undetectable. As a general rule, plastic lids sold as accessories must be used; these accessories are not part of the container, and it is desirable to cover the openings of these containers to cover and store product residue.

[0006] U.S. Patent 6,059,137A, dated May 9, 2000 (Westwood), U.S. Patent 4,979,635A, dated December 25, 1990 (Levine), U.S. Patent 4,673,099A, dated June 16, 1987 (Wells), or U.S. Patent 2,012,012,586A1 (Rinderer) uses elements of this patent specification; however, they neither use longitudinal supports for reinforcement in the definition of the technical problem nor provide a solution for the beverage can industry in their description of the technical state.

[0007] There is no doubt that any existing technology provides a solution for partially opening and closing the pouring orifice in a container lid, thereby allowing the metered pouring of the product (which is an integral part of it) and not just a simple accessory.

[0008] Therefore, there is a need for an integrated device for partially opening and closing a can with a metered flow supply function, providing the possibility of covering the pouring orifice and allowing its contents to be metered out by pouring (especially in cans with a circular base). This is where the present invention comes into play. Summary of the Invention

[0009] An integrated device for opening and closing cans and tin cans, using a non-deformable partial cap to allow partial emptying of their contents and subsequent closing of the containers, having a separable partial cap as an integral part of the container lid, the partial cap being defined by a defining scoring line and having a rod for separating the partial cap, whereby the rod is centrally riveted. The rod is securely connected to the lid of the container using a known technique such as riveting (center riveting) or similar methods, characterized by the following facts: the rod includes a riveted end comprising the surface of a center riveting in the same part, which is equipped with a tear-out extension of the rod and provides a fold toward the lid, while the opposite ends arrange a handle together with the upper cover of the partial lid, wherein the end and the remainder of the rod body are joined together by the center riveting to the surface of the lid of the container, while the rod includes a longitudinal connection between the riveted end and the opposite end of the handle, two non-deformable lateral crosspieces having the same peace of shape before the applied force tears the partial lid, as they handle longitudinally coated supports for reinforcement, in which die-cuts are made, forming a transverse folding axis at their ends connected to the end of the handle, and the partial lid handles the two connections of the lid toward the container and includes a non-deformable surface.

[0010] According to another aspect of the invention, the rod has a tear-off extension arranged between two non-deformable lateral latches, having three free sides and a fourth side connected to the end of the handle, the opposite side having a transverse and vertical fold at its end toward the crease of the lid of the container.

[0011] According to another aspect of the invention, the rod is provided with an end of the handle as a connection to the tear-off extension, and two non-deformable lateral latches of the same object, the rod having a diameter greater than that of the ellipse below it and surrounding the crease line of the ellipse.

[0012] According to another aspect of the invention, the rod has a lateral folding axis on the side of the tear-off extension, connecting the handle end and the ends of two non-deformable lateral latches (cross pieces) having the handle end.

[0013] According to another aspect of the invention, the end of the handle of the rod is provided with a protrusion on the upper surface for gripping by the fingers during its vertical movement.

[0014] According to another aspect of the invention, the end of the handle of the rod has a semi-soft material sealing gasket disposed on the lower surface of the upper cover of the partial cover, which (the partial cover) has a larger diameter than its (the sealing gasket's) diameter in order to achieve a tight closure.

[0015] According to another aspect of the invention, a partial cover has a groove around it, which is fixedly connected to the remainder of the container's cover by two parallel interruptions on the central side of the groove, and has a central rivet that provides a lateral axis for the partial cover's fold toward its vertical position.

[0016] According to another aspect of the invention, the partial cover is equipped with a longitudinal central support that ensures it is not deformable when lifted to a vertical position by a force applied to the folded portion extending to its lower surface.

[0017] According to another aspect of the invention, the fold towards the lid is non-deformable because the longitudinal support of the fold cuts the partial lid's crease between two parallel interruptions with the cutting edge of the fold, due to the width being smaller than the distance between the interruptions and due to the lateral angle of the lid towards the container relative to the body of the rod.

[0018] According to another aspect of the invention, by manually and gradually raising the rod to bring the side of the end of the handle to a vertical position, the folded portion is disengaged and the partial cover is raised to a vertical position (with its inner side).

[0046] The following is a description of the use of an integrated device (1) for opening and closing cans and tin cans with non-deformable partial lids for food containers, which is the subject of this invention.

[0047] However, this should not be construed as a limitation of the invention, but rather as an illustration by way of example, as previously stated, the apparatus of this application can have many more applications.

[0048] Refer to the attached diagram. Figures 1 to 6 Firstly, it is observed that, as the object of the present invention, an integrated device (1) for opening and closing cans and tin cans with non-deformable lids includes a rod (6) with a tear-off extension (8) at one end, a fold (9) facing the lid (4), and a handle (10) at the other end. It is provided with an upper cover (11) of a partial lid and a partial lid (3), which has two connecting parts facing the lid (4) of the container (2) and has a non-deformable surface.

[0049] from Figure 1 The integrated device (1) for opening and closing cans and tin cans with non-deformable partial lids can be seen in the middle, which is visibly in mint condition, including a rod (6) with a handle (10) at the end, a connection in the shape of two non-deformable lateral latches (14) and a surface (12) of a central riveting on the upper surface of the lid (4) of the container (2), which is riveted to the lid of the container and the partial lid (3) before the partial lid is separated.

[0050] Figure 2A top view of the rod (6) as a component is shown, showing the lateral folding axis (16) of the non-deformable lateral latch (14).

[0051] exist Figure 3 In the view, the vertical plan of the rod (6) can be seen, showing the fold (9) that bends downward from the same part, the protrusion (17) on the upper surface, and the sealing gasket (18) on the lower side of the end of the handle (10).

[0052] Figure 4 It is a perspective view of the lid (4) of the container (2), in which the rod (6) is removed, and the scoring line (5) can be seen, which is surrounded by its two parallel interruptions (19) around the part of the lid (3), and the position of the central rivet (7).

[0053] exist Figure 5 A cross-section of a container (2) with a lid (4) is shown in a front view, wherein a portion of the lid (3) is separated and raised by a fold (9) of a rod (6).

[0054] Figure 6 A perspective view of the cover (3) as a component, viewed from below, is shown, showing the longitudinal central support (21).

[0055] To use the aforementioned integrated device (1) for opening and closing cans and tin cans with non-deformable partial lids, firstly, the intended portion of the lid (4) of the container (2) is separated manually by tearing it open at the end of the handle (10) of the rod (6), and then the fingers of one hand are used to pull upwards to grasp the protrusion (17) on the upper surface. The cut of the fold (9) has the intended section of the crease (5) at the cut edge (23) of its fold, which surrounds the partial lid (3) between two parallel interruptions (19).

[0056] Once the rising angle of the rod (6) matches the angle of the folding part (9) relative to the rod body, its inner side contacts the longitudinal center support (21) on the inner side of the partial cover (3).

[0057] Due to the longitudinal central support (21) of the partial cover and the longitudinal support (22) of the folding portion surrounding the folding portion of the partial cover and the transverse folding axis (16) at the end of the non-deformable lateral latch (14) and the non-deformability of the handle, the partial cover (3) is gradually opened at an angle of up to 180° relative to the initial position after separation at the crease line.

[0058] Then, continue to tilt container 2 to pour out the contents. This allows the contents of the container to be emptied to the desired amount.

[0059] Once the pouring action is nearing completion, proceed to close the opening in the cover (4) and return the rod (6) and the portion of the cover (3) located below the end of the handle (10) to their initial position.

[0060] The sealing gasket (18) remains engaged with the cap (4), covering the crack between the cap and the cap (4) through the inside of the handle (10), which is caused by the breakage of the etch line (5) during the opening action due to the large diameter of the handle relative to one of the caps and due to the semi-soft nature of the gasket. The container (2) remains airtight.

[0061] To achieve further evacuation, first, pull the handle (10) upward as previously described to close it by returning the handle to its horizontal position in the opposite direction.

[0062] An integrated device (1) for opening and closing cans and tin cans with non-deformable partial lids allows for desired or necessary opening and closing until the container (2) is completely emptied.

[0063] Obviously, the integrated device (1) for opening and closing cans and tin cans with non-deformable partial lids, which is the object of the present invention, will be used for purposes other than for food contents, and will be accomplished in the same manner as described above, by pulling the handle (10) up or down to open or close, and the previous action of the folding part (9) of the tearing extension (8) of the lever (6) separating the partial lid (3) in the lid (4) by the movement from the horizontal position to the vertical position, so as to manipulate the opening and closing device in the container (2) before the first use of the container (2).

[0064] Therefore, the present invention has created an integrated device for opening and closing cans and tin cans with non-deformable lids, which provides several advantages, particularly the following:

[0065] - Simple structure, therefore easy to use.

[0066] - It is actually used due to the versatility and diversity of its applications.

[0067] - Presented in an aesthetically pleasing manner, as the integrated device for opening and closing the can and tin can provides the appearance of being in perfect condition while awaiting initial use and subsequently for storing any remaining unconsumed contents.

[0068] The preceding description focuses on the essential features of the invention.

[0069] However, it should be understood that the described device can be modified in its shape and structure without departing from the results of the invention. Therefore, the scope of the latter is limited only by the content of the appended claims.
