Definitions
- the present invention refers to a bottle cap of plastic material, of the type that is anchored to the neck of the bottle by means of curling or clipping, also known by the English term "snap-on”.
- both the projection and the wall have a surface of interference with each other (ie, contact) perpendicular to said axis.
- this cannot be obtained in the caps obtained by molding, since in order to enable their demoulding, the fixing projection and the inner side wall of the plug must form an angle greater than 90 °. The value at which this angle exceeds 90 ° is called the demoulding angle.
- This type of plug is susceptible to being violated in two ways, either by achieving a horizontal displacement (that is in the direction of the plane perpendicular to the axis of the plug) or by getting the flexible band to slide between the inner face of the wall of the plug and the wall of the neck until it comes out enough that it does not perform its function (similar to the mechanism of extraction of a sock)
- the outer interference face replaces the interference face of the projection, but presenting a right or acute angle with respect to the side wall of the plug (or, in other words, with respect to the axis of symmetry of the plug) This eliminates the possibility of the plug violation taking advantage of the demoulding angle, which makes it necessary for the protruding face of the projection to be greater than the right angle.
- This innovative system can be used in all types of plugs, even in plugs with tear pre-cut seal integrated into its side wall. However, it has greater advantages in enclosure caps, which lack a pre-cut tear seal integrated into its side wall.
- One possible way to ensure that the band is flexible is by weakening the thickness in the area where the band is connected to the cap.
- Figure 4 shows an enlarged detail of the section of Figure 3.
- Figure 5 schematically shows an elevation view of the example of the cap of Figure 1 shown, placed in a bottle, with the flexible band folded into the cap.
- Figure 6 shows a cross section of Figure 5.
- Figure 8 is a section similar to that of Figure 7, in which for clarity, the neck of the bottle has been removed, representing the band in a folded position.
- Figure 9 is another cross-section according to a plane perpendicular to the sectional plane of the section shown in Figure 6.
- Figure 1 shows a plug consisting of a plug-spout of the type that is usually used for vegetable oil containers.
- the cap -1- has an upper cover -2- and a lower part -3- intended to be attached to the bottle neck -100- (see figure 5).
- the lower part -3- is anchored by means of a clipping system, encliquetado or snap-on, being placed under pressure in the neck -100- of a bottle. Once the plug is placed, the interference caused by a clipping system, or snap-on, prevents the entire plug from being removed.
- the lower part -3- has a liquid outlet duct formed by the wall 33.
- the duct is sealed by a tear-off membrane -36- made according to known techniques.
- the tear seal may be similar to that shown in Spanish Patent Documents ES10002900U or ES2162585.
- the upper part -2- has a cylindrical fin -23- to seal the duct formed by the wall -33- when the plug is in a closed position, thus preserving the plug tightness.
- the anchoring system of the cap -1- to the bottle -100- is located in its lower part -3-.
- the first element of the system consists of a projection -31- located in the inner side wall of the plug -32-.
- the projection -31- has a first interference face -311-, which forms an obtuse angle with the inner side wall -32- and a second face -312- which forms an acute angle with the interference face -311-.
- the inner bottom edge of the side wall of the bottom piece -3- has a continuation in the form of a flexible band -4-.
- the term "flexible band” indicates in the sector that the band can bend towards the inside of the cap, without being an additional indication of other characteristics or areas of the band, which could be, for example, of a rigid nature.
- That band flexible -4- or "flexband” has a geometry that corresponds to the geometry combined with that of the projection -31- and the inner face -32- of the side wall of the plug.
- the flexible band -4- has an inner support face -411- that comes into contact with the interference face -311- of the projection -31- when the flexible band bends towards the inside of the plug, and a second inner face -412- conjugated with the shape of the second face -312- of the projection -31-.
- the flexible band 4 of the example ends in a skirt -42-, which when the flexible band is bent towards the inside of the plug, and the interference face -311- of the projection -31- and the first inner contact face -411 - of the flexible band -4- come into contact, the skirt -42- is parallel to the inner face -32- of the side wall of the plug.
- the band 4 defines an outer interference face -43-.
- This face approximately coincides with the area of the corresponding band the inner contact face -411- and its function is to create an interference surface with a wall -101- of the bottle neck -100-.
- the use of a flexible band -4- that can be folded allows, in a bent position, the interference surface -43- to be perpendicular to the axis of revolution of the plug or, which is the same, to the inner wall -32- of the plug, that makes the interference with the interference surface -103- of the aforementioned interference wall -101- totally perpendicular to an axial extraction movement.
- the present invention allows said interference wall -101- located in the neck of the bottle -100- to come into contact with the skirt -42- and imprison it against the inner wall -32- of the cap. To favor this effect, it is possible to lower the wall -32- in the reception area of the skirt -42-.
- the band -4- joins the lower part -3- of the plug -1- through a narrowing -41- of the wall, which allows the flexibility of the band and a certain resistance and rigidity in the rest of the zones of the band -4-.
- the cap rests on a larger wall -102- of the bottle -100-.
- This wall -102- also collaborates, additionally, in preventing the violation of the cap by accessing the area between the bottle and the cap.
- the flexible band -4- can be folded inwards, leaving the cap ready for fixing to a bottle -100- by means of encytting.
- the type of cap especially its upper part, can be, for example, of any known type. It is also It is possible, in particular, to omit the second inner contact face of the band, whereby the narrowing of the band to the plug can be minimized or completely eliminated, among other examples.
