Description

TECHNICAL FIELD OF THE INVENTION



[0001] The present invention relates to a container that comprises a vessel and a lid coupled to said vessel, such that it has a simple and inexpensive configuration.

BACKGROUND OF THE INVENTION



[0002] Many types of container are known used to store different types of products, whether food stuffs or other, such as toys, school material, etc.

[0003] In some of these products, particularly those for food stuffs, it is sometimes necessary to have a hermetic seal of the lid on the vessel for a correct conservation of the food stuffs, without liquids leaving or entering the container during its storage.

[0004] Several solutions are known for achieving this hermetic seal of the union between the lid and the vessel that use watertight gaskets or other sealing methods to retain liquid in the container.

[0005] However, it is not always possible to seal the container correctly, with areas in the union between the lid and the vessel allowing liquid to enter or exit the container.

[0006] In addition, in some known solutions it is difficult to know whether the lid is uniformly engaged in the vessel, leading to liquid spills in case of slight impacts or shaking of the container.

DESCRIPTION OF THE INVENTION



[0007] In view of the foregoing, the present invention relates to a container comprising a vessel, a lid, and a gasket housed in an internal groove of the lid. This lid with gasket is coupled to said vessel.

[0008] This lid has a central portion surrounded by a side edge that extends downward from the central portion. The central portion and the side edge conform an internal space of the lid.

[0009] The side edge has at least two handles as portions of said lateral lip, disposed on opposite sides of the lid, regardless of its shape.

[0010] The vessel has a base wall surrounded by at least one side wall, the top end of which ends at a peripheral edge, the base wall and side wall conforming an internal space of the vessel.

[0011] In this way, the side wall of the vessel can be configured with a cylindrical shape having a circular or oval base, or a prism shape with a triangular, square, rectangular, pentagonal, hexagonal etc. base.

[0012] In order to achieve a correct coupling of the lid and the vessel, the configuration of the central portion and the side edge of the lid will depend on the cross section defined by the side wall or walls of the vessel, that is, circular, oval, triangular, square, rectangular, pentagonal, hexagonal, etc.

[0013] The container is characterised in that it has at least two retainer tabs located near each handle. These retainer tabs project from the side edge into the internal space of the lid.

[0014] Thus, when the lid is coupled to the vessel, the side edge of the lid, in the areas near the handles, is deforms outwards, and the retainer tabs of the lid engage some coupling areas of the peripheral edge of the vessel, thereby closing the vessel against the lid.

[0015] Advantageously, a hermetic seal of the container is obtained in a simple manner with a low cost.

BRIEF DESCRIPTION OF THE DRAWINGS



[0016] This specification is supplemented with a set of drawings illustrating the preferred embodiment, which are never intended to limit the invention.

Figure 1 represents a front perspective view of the container.

Figure 2 represents a lower perspective view of the container.

Figure 3 represents an exploded perspective view of the container.

Figure 4 represents a cross sectional enlarged view of one of the areas of the peripheral edge of the vessel where the retainer tabs engage the lid.


DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION



[0017] As shown in figure 1, the container comprises a vessel (2) and a lid (1) that is coupled to said vessel (2).

[0018] The lid (1) has a central portion (1.1) surrounded by a side edge (1.2) that extends downward from the central portion (1.1). The central portion (1.1) and the side edge (1.2) conform an internal space of the lid (1).

[0019] The side edge (1.2) has at least two handles (1.3) that are portions of said side edge (1.2) disposed on opposite sides of the lid (1). These handles (1.3) extend outward from the side edge (1.2) with a curved bevelled lip shape.

[0020] The handles (1.3) allow opening and closing the container. For this purpose, at least two retainer tabs (4) are disposed very near each handle (1.3).

[0021] As seen in figures 2 and 3, the retainer tabs (4) jut out from the side edge (1.2) towards the internal space of the lid (1) and are shaped as curved hooks that extend towards the central portion (1.1) of the lid (1).

[0022] These retainer tabs (4) can be disposed in the same area.

[0023] Figure 3 also shows how the side edge (1.2) can include an internal groove (6) disposed along the entire perimeter of the upper part, which projects into the internal space of the lid (1).

[0024] The internal groove (6) houses a gasket (7), providing a hermetic seal of the vessel (2) against the lid (1).

[0025] The vessel (2) has a base wall (2.1) surrounded by at least one side wall (2.2) to define an internal space of the vessel (2).

[0026] The vessel (2) can be formed by a single side wall (2.2) with a cylindrical shape having a circular or oval base, or by a plurality of side walls (2.2), determining a prismatic shape with a triangular, square, rectangular, pentagonal, hexagonal, etc. base.

[0027] The upper end of the side wall (2.2) ends at a peripheral edge (2.3) that defines a trunco-conical section leading away from the internal space of the vessel (2).

[0028] The lid (1) rests on the peripheral edge (2.3) when it is coupled to the vessel (2). For this reason, this peripheral edge (2.3) has union areas (2.3.1) reinforced with stiffening ribs (5).

[0029] The configuration of the central portion (1.1) and the side edge (1.2) of the lid (1) will depend on the cross-section of the vessel (2) defined by its side wall or walls (2.2), that is, circular, oval, triangular, square, rectangular, pentagonal, hexagonal, etc., in order to achieve a correct coupling of the lid (1) to the vessel (2).

[0030] When the lid (1) is coupled to the vessel (2), the side edge (1.2), in its areas next to the handles (1.3), is momentarily deformed outward, and the retainer tabs (4) of the lid (1) engage the union areas (2.3.1) of the peripheral edge (2.3) of the vessel (2).

[0031] In this way, a hermetic seal is obtained for the container in the union of the lid (1), gasket (7) and vessel (2), with great simplicity and low cost.
