Abstract

PROVISION INTRODUCED BY HANDLING FOR UNCUTTING COVER. Said handle (1) being formed by two symmetrically opposed rods (2), each developed in a straight posterior portion (2a) followed by a curved front portion (2b), the curved front portions (2b) of said rods (2) being articulated to each other by their free ends, where the pivot axis (3) is provided, and the internal lateral face of the straight sections (2a) is developed in chamfer (2aa), which configures abutment stop between the two said rods (2), while the inner lateral face of the curved sections (2b) is serrated (2bb), and delimits the ideal circle formation (C); the rods (2) may overlap one another or move away from one another by decreasing or increasing the diameter of the circle (C) initially formed by the inner side faces (2bb) of the rods to surround caps (T < ) or (T <) with respectively smaller or larger diameters.

Description

"PROVISION INTRODUCED IN HANDLING FOR UNCUTTING COVER".

As is well known in the art, the cylindrical caps used to close the PET bottles are screwed very tightly into the bottle neck after bottling the beverage, obviously to provide the tightness and safety required for such a product. For this reason, unscrewing said caps at the time of opening the bottle requires considerable effort on the part of the user, constituting a relatively difficult operation, especially for housewives -

Devices are already known in the art to assist in unscrewing this type of lid; however, such devices are restricted to a certain cap diameter, or at most a slight variation over or under a certain cap diameter, and therefore cannot be used to open any bottle or package provided with such cap. type of closure (for example, packs of medicaments having substantially smaller diameter closures which are also difficult to open).

The present Utility Model patent relates to a new "Introduced Handling Arrangement for Lid Unscrewing", whereby said handle is formed by two duly hinged rods, whose inner side faces together delimit In the front region of the device, the formation of a circle with diameter preferably coinciding with the diameter of the caps of the usual PET-type bottles, which circle, surrounding the outer face of said caps, facilitates their grasping and unscrewing them upon initial opening. from the bottle.

Also according to this new arrangement, and constituting the great differential of this new device in relation to the usual ones, the rods of the now innovated handle can overlap each other, in order to reduce the diameter of the front circle delimited by them, and thus wrap lids with smaller diameters; furthermore, said rods may also be spaced apart from each other to allow for increasing the diameter of the front circle delimited by them, and thus to surround larger diameter caps.

Thus, with this provision, the innovative handle now covers a wide range of diameters and can thus be used in virtually all usual containers, from 1, 1.5 and 2 liter PET bottles. , even the small packages of medicines in general.

For illustration purposes, following are drawings of the present model, through which it will be better visualized:

Figure 1 is an exploded perspective view of the innovated handle showing the two rods that compose it, duly articulated to each other by their front ends;

Figure 2 is also a perspective view of said handle now in assembled position;

and Figures 3, 4 and 5 are top views of said handle illustrating the possibility of use thereof over a wide range of diameters, facilitating unscrewing from smaller caps (figure 3) to larger caps (figure 5).

Of course, although three cap diameters have been shown herein, they have been illustrated by way of example only, and the present handle may be employed on any other cap diameter larger or smaller than those illustrated herein.

The subject-matter of the present Utility Model patent is a "MANUALLY INTRODUCED ARRANGEMENT FOR COVER UNRUPTING", whereby said handle (1) is formed by two symmetrically opposed rods (2), each developed in a straight posterior section. (2a) followed by a curved front portion (2b), the curved front portions (2b) of said rods (2) being properly articulated to each other by their free ends, where a pivot axis (3) is provided, with the The internal lateral face of the straight sections (2a) is developed in the middle chamfer (2aa), which configures the abutment stop between the two rods (2), while the internal lateral face of the curved sections (2b) is serrated ( 2bb), and, when mutually engaging the chamfers (2aa) of the rods (2), together delimit the formation of an ideal circle (C) with preferably coincides with the diameter of tube caps (T) of the usual type PET bottles (see Figures 1, 2 and 4).

Thanks to this new arrangement, and constituting the great differential of this new device in relation to the usual ones, the rods (2) of the now innovated handle (1) can come out of the seat position between their chamfers (2aa) (figure 4), and overlap each other to allow a reduction in the diameter of the circle (C) bounded by the inner side faces (2bb) of their portions (2b), thus enclosing caps (T <) with smaller diameters (see figure 3); in addition, said rods (2) may also be spaced apart from each other to allow for an increase in the diameter of the circle (C) bounded by the inner side faces (2bb) of their portions (2b), thereby enclosing caps (T> ) with larger diameters (see figure 5).

Thus, whatever the diameter of the caps to be unscrewed, the serrated inner side face (2bb) of the curved portions (2b) of the handle (1) now innovates surrounds the outer face of said caps, facilitating the gripping and unscrewing of the caps. same when opening the bottle.

Accordingly, with this provision, the innovated handle (1) has now encompassed a wide range of diameters and can thus be used in virtually all usual containers, from PET bottles to small packages of medicines in general.
