Definitions
- the present invention relates to a closure cap for an easy-open container. More specifically, the invention provides a closing lid for a container of the so-called commonly easy-open and intended to contain any type of packaged food, the container being of the type that consists of a metal body, in particular cylindrical , and a closing lid initially integral to the container, the opening of which is carried out by pulling a ring arranged on the exposed face of said lid and fixed to it by a rivet.
- Containers commonly referred to as “canning cans” equipped with an easy-open system are well known.
- These easy-open opening systems usually consist of a lid that can be attached to the container in a detachable way thanks to a cut line designed to weaken it and that has a pull ring on its exposed face that allows the lid to be angularly separated, exposing at least part of the content of it.
- the need to pull the ring involves first applying a force to partially separate said ring from the surface of the cover and, secondly, an upward pulling force on the ring that allows it to be dragged with the ring itself. lid in order to separate it from the body of the container.
- the upward pulling force on the ring it depends not only on the resistance of the cutting line at the periphery of the area where the lid is attached to the container, but also on the design of the rivet itself, since the Opening of the lid is usually facilitated by the levering force that one end of the ring in the area of the rivet makes on the body of the can, thus being limited to the angle in which the ring is pulled to approximately 22 Q.
- the present invention solves the aforementioned disadvantages of the canned cans already known, providing a closing lid for a container of the so-called commonly easy-open intended to contain any type of packaged food where essentially the special shape of the rivet that joins the cover pull ring allows easy opening with a greater angle of lifting of the ring and without risk of detachment.
- the container is of the type made up of a metal body, in particular a cylindrical one, and a closing cover initially integral to the container, the opening of which is carried out by pulling a ring arranged on the exposed face of said lid and fixed to it by a rivet.
- the closure cap of the present invention is of the type with a pull ring attached to the lid of a metal container by means of a rivet.
- Said pull ring is essentially wedge-shaped rounded at its widest end and trapezoidal at its opposite end, being joined by this trapezoidal end to the cover by means of a rivet.
- the ring has a trapezoidal depression that also has a U-shaped line of weakness that partially surrounds the circular rivet. Also at this end, the ring has an essentially triangular extension whose vertex defines the point of support of the ring against the cover for opening.
- This design of the ring and rivet assembly of the cover of the invention allows an opening with an angle of 29 Q , significantly greater than that They provide the easy-open lids of the state of the art, thereby facilitating the opening of the container and avoiding the aforementioned drawbacks.
- Figure 1 a top view of the closure cap of the invention.
- Figure 2 detail of the ring of the cover of figure 1.
- Figure 3a sectional cut of a conventional cover in the area of the ring.
- Figure 3b sectional cut of figure 3a in the lifting state of the ring.
- Figure 4a section cut according to line A of the cover of figure 1 through the area of the ring and detail of recess.
- Figure 4b sectional cut of figure 4a in the lifting state of the ring.
- the closure cap (1) of the present invention is of the type that has a pull ring (2) attached to the lid (1) of a metal container by means of a circular rivet (3 ).
- this pull ring (2) is essentially wedge-shaped rounded at its widest end and trapezoidal at its opposite end, being joined by this trapezoidal end to the cover (1) by means of the rivet (3 ).
- the ring (2) has a trapezoidal depression that includes a weakening line in the form of a U (4), partially surrounding the rivet (3). Also at this end, the ring has an essentially triangular extension (5) whose vertex defines the point of support of the ring against the cover for opening. In use, during the lifting of the ring (2) and the separation of the cover (1), the cooperation of the weakening line (4), the extension (5) and the rivet (3) allows the opening of the cover .
- the ring opening angle is determined by the diameter (A) of the rivet (3) and by the distance (B) from the point (10) where the line of weakening ends ( 4) to the tip of the ring, which is the area that exerts force on said line of weakness to break the metal.
- an intermediate zone (C) between the rivet (3) and the tip of the ring is deformed thanks to the line of weakness and the geometry of the assembly.
- Figure 3b shows that the angle between the cover and the raised ring is 22 Q in a conventional cover.
- the cover provided by the invention and in particular the assembly of the ring (2) and the rivet (3) allows a larger opening to a conventional cover, such as an angle of 29 Q in front, than the 22 Q of a conventional cover, thereby facilitating the opening of the container and reducing the force necessary for it.
- this distance (B ’) is 2.75 mm.
- the diameter (A) of the rivet (3) is increased.
- the cover of the invention has, in correspondence with the essentially triangular extension (5) whose vertex defines the point of support of the ring against the cover, a concave recess (6) that facilitates the pivoting of the end of the ring on the cover in order to further aid opening.
- said recess has a radius of 0.7 mm.
- the rounded end opposite the area of the rivet of the pull ring (2) forms an angle of 174 Q with respect to the plane of the surface of the cover, allowing 29 Q to be reached at the tip end of the ring faster.
