Abstract

Improved lid with a hinged cap for containers, made from three independent bodies, the first base body (1) having a pourer opening (1a), with an internal threaded section (1b) to fit onto a threaded section of a container; a second upper body (2) or lid that is hinged to the first base body (1) by means of a downward extension (2b) that acts as a hinge and a third external body (3) that fits to the first base body (1) in such a way that it wraps around it externally and laterally. The external third body (3) has a perimeter groove (3a) on the internal side wall aimed at the fitting of a peripheral rib (1c) fitted into the external wall of the first base body (1). The downward extension (2b) has a barb shaped protrusion at the end that may be fitted in a cavity located in the first body (1) between the threaded section (1b) and an intermediate wall.

Description

Improved cap with flip top.

Object of the invention

The object of the present invention is a plug perfected with a folding lid for packaging that incorporates notable innovations and advantages over other available plugs in the market.

Background of the invention

Currently, a wide variety of Plastic caps for different types of packaging. The plug that described below is the type that presents a base body that includes a spout that protrudes above it and a flip top cover, such as the cap described in the Model Utility No. ES 1031 134 U belonging to the same applicant as the present invention However, the cap described in that record is formed by a single body since both the base body intended to be fixed to the container as the cap are attached so solidarity by the hinge area.

Due to this configuration and construction of that plug, the material used for both parts is the same, of so that it requires the use of a plastic material that is the most suitable for both, a fact that does not imply that it is the most appropriate for the function that each part of the cap does.

It is also known in US Patent No. 5 348 201 a folding top closure provided with an articulated plug by a plug or similar that implies more components and by consequently a complex and expensive configuration.

Patent No. EP-A-0 340 352 describes a package provided with an elastically reversible hinge.

Features described in the patent American No. 5 348 201 correspond to the preamble of the claim 1 of the present invention.

Description of the invention

The present invention has been developed with the in order to provide an improved plug that solvent the drawbacks mentioned above, also providing other advantages that will be evident from the description that accompanies next.

The perfected cap for packaging of the invention is made of three independent parts in a way which allows a greater combination of different colors or designs, being a first base body that has a pouring hole, which It has an internal threaded section to fit a section Threading of a container, a second upper body that acts as a lid, which is hinged to the first body and a third body exterior that attaches to the first body in such a way that it wraps it outwardly and laterally.

Being the body that acts as a cover independent from the base body, allows the manufacturer make said cover body with a more flexible material than the rest of the cap assembly thus improving the characteristics of movement and resistance of the body as a cover.

According to this invention, the third outer body It has a perimeter groove in its inner side wall intended for the coupling of a peripheral nerve provided in the outer wall of the base body.

Advantageously, the descending extension it presents at its final end a projection shaped like a harpoon intended to engage in a cavity located in the first body, more specifically, between the threaded section and an intermediate wall, so that it acts as a fixing method that prevents the exit of the hinged section.

Other features and advantages of the cap perfected object of the present invention will be apparent from the description of a preferred embodiment, but not exclusive, given by way of non-limiting example in the drawings that are accompanied, in which:

Description of a preferred embodiment

As shown in Figures 1, 2 and 3, a first embodiment of the cap of this present invention is formed by three independent bodies that use materials moldable plastics, the first base body (1) has a pouring hole (1a) for the exit of the liquid from the container and an inner threaded section (1b) to fit a section threading of a conventional container (4) partially shown, a second upper body (2) acting as the cover itself of the that a shutter protrudes (2a), which is hinged to the first body (1) by means of an extension descending (2b) with its end in the shape of a harpoon that acts hinge and a third outer body (3) that attaches to the first base body (1) in such a way that it wraps it outwardly and sideways. It is worth mentioning that the material used in the body of the cover (2) has greater flexibility than the material used in the two other components or bodies. Harpoon shape above mentioned is intended to be fixed in a cavity in the first base body (1), more specifically, between the section threaded (1b) and an intermediate wall (as can be seen with greater clarity in figure 1), to avoid its release form unwanted body (2) by the user during the operation of opening or closing

The third outer body (3) presents in its inner side wall of a perimeter groove (3a) intended for the coupling of a peripheral nerve (1c) that is provided in the outer wall of the base body (1).

In Figures 4 and 5, a second one has been made embodiment of the cap of the present invention with the only difference from the one described above in the form geometric of the plant that in this case is rectangular.

The details, the shapes, the dimensions and other accessory elements, as well as the materials used in the Manufacture of the perfected cap of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention nor of the scope defined by the claims included in continuation.

Claims (3)
