Description

CONTAINER CAP WITH PLUG Technical Field The present invention relates to a container lid. More particularly, the invention relates to a container lid for use in containers containing flowable materials such as paint.

BACKGROUND ART There are several patents related to containers for flowable materials. One is US Pat. No. 5,921,448 issued to Steward Michael, which describes a closure cap wherein the central region is provided with a groove, and is formed in such a way that, under the action of a weight of one paint applied to the central region, the groove expands and a flow of paint can flow through the expanded groove. In addition, paint container lids are described in U.S. Patent Nos. 3,715,982; 3,366,272; 3,899,107; 4,009,802; 4,034,901; 4,203,537; 4,893,723; 4,917,714; 4,949,884; 5,012,960; 5,388,715; 5,392,969 and 5,975,346. However, there is a need to provide a container lid that facilitates the introduction of colored paint pigments into the containers, and which is then sealed before the paint mixed with the color pigments is used.

In a prior art method for mixing base paint with color pigments, the existing closure is removed. The color pigment is introduced into the base paint contained in the container. The closure (often damaged or indented after its initial removal) is reapplied, and the package (container) is placed in a mixing machine, on which, the rotation / vibration of the container mixes the paint. This method has been very unsatisfactory, due to the spillage of the paint during the mixing process and / or during the removal of the lid. The refixing of the closure cap on the container often does not create a tight seal, resulting in paint spills during transport of the container containing the mixed paint, to the premises of the customers. The initial removal of the closure of the containers causes damage to the lock / seal mechanism, both in plastic and metal containers. In another prior art, after selecting the preferred color pigment, a hole is drilled in the closure or in the top panel of the container, to allow the introduction of the color pigments in the base paint through the hole. After the introduction of the color pigment, a plastic / rubber plug / stopper is fitted over the hole, effectively resealing the container. The container is then placed in a vibrating / mixing machine, to completely mix the color pigment in the base paint. This method is an improvement over the method described above, in that the closure is not removed, and only a small amount of paint can escape from the orifice / plug assembly. However, the methods of the prior art suffer from disadvantages. An additional device or device is needed to drill a hole / hole in the closure cap. This involves an extra operation, where occasionally the perforated part falls back into the container containing paint. In addition, the second method also involves an additional cost for the plug / obturator. Another drawback is that the flow direction of the flowable material can not be controlled from the container. Accordingly, there is a need to provide a closure cap and a container, wherein the drawbacks are reduced or exceeded.

SUMMARY OF THE INVENTION A lid for a container comprising a body having a peripheral region that can be engaged with a rim of the container, such that this body can be mounted on the container. The body is provided with a stopper consisting of an arrow portion with a flange member, an annular collar separated from the flange member by a neck portion., and being able to separate the plug from the peripheral edge, demarcating a hole when removing the plug from the body. The separate plug can be readjusted in the body by exerting force on the plug, in such a way that the neck portion engages on the peripheral edge of the body. The arrow portion is secured to the peripheral edge of the body by fragile lines of weakness. The cap and the body of the lid are formed as a one-piece element composed of an elastic material. The arrow portion of preference is hollow. The annular collar is wedged in a vertical cross section. The plug is disposed in a recessed portion of the body, such that, in a molded position, the plug is below the surface level of the non-recessed portion of the body. A landfill is provided to control the flow of material from the container. The open ends can be adjusted to the hole and to a circular lip provided on the plug.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figure 1, a plug (10) is shown in its molded position in a closure cap (12), which can be secured to a container, typically a wide-mouth container. The plug (10) is of a cylindrical shape, with a circular flange (14) and a cylindrical arrow portion (16). The plug (10) is secured to the closure cap (12) by brittle lines of weakness (18) that surround and form along the arrow portion (16) of the cap (10). Separated from the circular flange (14) is an annular collar (20) along the arrow portion (16). The arrow portion (16) can be a solid portion or a hollow portion, as shown in Figure 1. The cap (10) is preferably placed in a recessed portion (22) in the central region of the closure cap (12) (see Figures 3, 4, 5, and 8). This configuration allows the circular flange (14) of the cap (10) to be at the same level as the non-recessed portion of the closure cap (12). It would be appreciated that the plug (10) could be located in the middle portion of the closure, or in an off-center position of the closure lid (see Figure 5). The plug (10) is removed from the closure cap (12) by twisting the cap along the longitudinal axis of the arrow portion (16) with one hand. Alternatively, a wrench-type apparatus (24), see Figure 7, is used to twist the plug (10) and separate it from the closure cap (12). The wrench type apparatus (24) can be applied in the neck portion (26) between the circular flange (14) and the annular collar (20), to remove the cap (10) from the closure cap (20). 12). In another embodiment, a pull tab (32) is provided on the cap (see Figures 9 and 10). By removing the cap from the closure cap (12), a pigment of the preferred color is introduced into the container through the hole (30) created by removing the cap from the closure cap. The hole is then closed by fitting the plug over the hole in the closure cap (12). The peripheral edge (28) of the closure cap (12) is hermetically coupled on the neck portion (26) of the arrow of the cap ensuring a tight seal. With the closure, the container is vibrated or rotated to provide a complete mixture of the pigments and the base paint. It will be appreciated that other materials may also be introduced into the container.

It will be appreciated that the neck portion (26) of the cap is determined and configured to provide a tight fit coupling over the hole (30), which is dimensioned and configured in a cooperative manner. The peripheral edge (28) of the closure cap is slightly malleable to allow the annular collar (20), which is one dimension larger than the size of the hole (30). This configuration prevents the adjusted cap (10) from being dislodged or disconnected from the closure cap (12). Although in the embodiment described herein, the plug is of a cylindrical shape, it can be appreciated that other geometric shapes of the plug, in particular of the neck portion (26), can also be adopted, and then a cooperative hole is formed ( 30) to receive the plug (10). The placement of the molded plug (10) in a recessed portion (22) of the closure cap (12) makes it possible, firstly the stacking of one container on top of another similar container, and second, it prevents accidental dislodging of the cap (10) of the closing lid (12) (see Figures 4 and 5). In the embodiment just described, the flow direction of the paint or other flowable material from the container can not be controlled through the orifice (30), and to facilitate the controlled flow of the material from the container, a weir is provided (34). ). The landfill (34) comprises a tube with open ends. One end of the weir (34) includes a pair of annular flanges (36) adapted to snap fit on the peripheral edge (28) of the closure cap (12) (Figure 15). The other open end of the weir (34) includes an annular groove (38) at the terminal end. The weir (34) preferably has an angular shape. The plug (10) includes a circular lip (40) sized and configured to accommodate instantaneously holding the weir (34) in the annular groove (38) (see Figure 17). The weir can be adjusted on the plug (10) in such a way that the open end is closed. The closure of the open end of the landfill prevents the entry of foreign matter into the container. It will be appreciated that the weir (34) can be separated from the lid of the container, and the plug (10) can be used to close the hole (30), as described above. A threaded element can be provided on the plug, in such a way that the weir can be screwed onto it. The container assembly, the closure cap (12) and the cap (10) can be used to pack other materials than paints. To remove the mixed paint, the closure cap (12) is opened by means known in the art, and does not form part of this invention. The provision of the fragile weakness line (18) in the cap serves as evidence of forcing, of an unauthorized removal of the cap from the container.
