Abstract

A snap closure with adjustment of its snap tension is described, comprising a male component (1) selectively engaged in a female component (2), such male component (1) and/or female component (2) being fastened to a respective supporting device (11, 21) designed to receive connecting means to a surface of a respective substrate, and further comprising at least one removable connecting device (3) designed to allow changing a geometric shape of at least one component of the snap closure.

Claims

1-8. (canceled)

9. A snap closure comprising a male component selectively engaged in a female component, the male component and/or the female component being fastened to a respective supporting device designed to receive connecting means to a surface of a respective substrate, the snap closure further comprising at least one removable connecting device designed to change a geometric shape of at least one component of the snap closure.

10. The snap closure of claim 9, wherein the removable connecting device is designed to interact with at least one portion of deformable material of the female component to change a seat of the male component.

11. The snap closure of claim 9, wherein the male component comprises an internal crown with an internal shrinkage, and the female component comprises an external crown with an external shrinkage, the external shrinkage being designed to receive the internal shrinkage, depending on a change of a portion of deformable material, the external shrinkage being mechanically connected to the portion of deformable material.

12. The snap closure of claim 11, wherein the female component comprises at least one notch obtained in a wall of the external crown and of the external shrinkage.

13. The snap closure of claim 12, wherein the at least one notch affects a part of the portion of deformable material.

14. The snap closure of claim 9, wherein the portion of deformable material is composed of a concave foil, the removable connecting device being composed of a threaded union pressing at a centre of the portion of deformable material.

15. The snap closure of claim 9, formed of axial-symmetric components.

16. The snap closure of claim 9, wherein the male component and the female component are made of foils or moulded plastics, and are fastened to their respective supporting devices.

Description

[0015] FIG. 1 shows a partial front and axial-symmetric sectional view of a first component of the embodiment of the snap closure with tension adjustment according to the present invention;

[0016] FIG. 2 shows a partial front and axial-symmetrical sectional view of a second component connected to a supporting material of the embodiment of the snap closure with voltage adjustment according to the present invention;

[0017] FIG. 3 shows a perspective view of the component of FIG. 1;

[0018] FIG. 4 shows a perspective view of the component of FIG. 2; and

[0019] FIG. 5 shows a perspective assembly view of the embodiment of the snap closure with tension adjustment according to the present invention.

[0020] With reference to the Figures, it is possible to note that a snap closure with adjustment of its snap tension according to the present invention comprises a male component 1 selectively engaged in a female component 2. The male component 1 and/or the female component 2 can be fastened to a respective supporting device 11, 21 designed to receive connecting means to a surface of a respective substrate.

[0021] Advantageously, the snap closure according to the present invention further comprises at least one removable connecting device 3 provided to allow changing a geometric shape of at least one component of the snap closure.

[0022] The removable connecting device 3 interacts with at least one portion of deformable material 4 of the female component 2 to allow changing the seat of the male component 1.

[0023] The male component 1 comprises an internal crown 13 with an internal shrinkage 14. At the same time, the female component 2 comprises an external crown 23 with an external shrinkage 24.

[0024] The external shrinkage 24 is provided to receive the internal shrinkage 14, depending on the variation of the portion of deformable material 4. In fact, the external shrinkage 24 is mechanically connected to the portion of deformable material 4.

[0025] Il female component 2 comprises at least one notch 5 obtained in the wall of the external crown 23 and of the external shrinkage 24.

[0026] Such at least one notch 5 affects part of the portion of deformable material 4.

[0027] The portion of deformable material 4 is composed of a concave foil, the removable connecting device 3 being composed of a threaded union pressing at the centre of the portion of deformable material 4.

[0028] Preferably, the snap closure is formed of axial-symmetric components.

[0029] The male component 1 and the female component 2 can be made of a foil or of moulded plastics, or through other working processes, and fastened to their respective supporting device 11, 21, for example through welding, screws, glues, adhesives, wires, etc.

[0030] The snap closure with adjustment of its snap tension of the present invention solves the above mentioned problems. In particular, the chance of modifying the unfastening force of the button by changing the tabs' width is obtained by acting on the adjustment of the female crown fastened on the basic plate or other type of support or substrate. By screwing a nut, a greater compression is obtained in the concave base of the female button, due to the resiliency of the material, allowing to move the tabs towards inside with a diameter reduction for the fastening.
