Definitions

• This invention concerns a closure/opening device for a container suitable for the containment of pourable products.
• said closure/opening device is of the three-piece type, namely it is equipped with a collar having a flange that can be associated with a perforate portion of the container, a cutting element that perforates the cutting portion during the first opening of the device, and an upper cap that is screwed to the collar and has the task of both controlling the movement of the cutting element at the first opening of the device, and to preserve the product that can be placed inside the container during the period in which the container, although open, has not yet been emptied of its contents.
• Said opening/closing device is extremely efficient, but it is not without drawbacks, especially in terms of environmental impact.
• the cap once removed, is not always repositioned on the collar because, either is carelessly thrown away by the user immediately after the first opening, or falls on the ground and, therefore, is no longer hygienically usable. This is clearly extremely damaging to the environment as the cap, as well as the entire opening/closing device, is made of plastic.
• Document DE102010028518 under the name Bosch GmbFI, describes a closing device that can be applied mainly to containers made entirely of plastic and that can be opened by means of suitable cutting elements that are activated when the container is first opened and that, once opened, can be conveniently opened and closed several times.
• This design describes, in particular, a closing device comprising a collar, a cutting edge and a rotating cap, equipped with a lower part and a lid which can also be rotated to the said lower part by means of a plastic hinge.
• the cap is associated with the collar and is attached to it in a way that can only be rotated by means of a lower cylindrical retaining element.
• the cap includes means for rotating the cutting element the first time the closing element is rotated with respect to the collar.
• a purpose of this invention is therefore to create a three-piece opening/closing device of the type described above that reduces, or completely eliminates, the problems of pollution caused by containers for pourable products of known art and that, at the same time, allows an efficient pouring of the product present in the container on whose upper face the opening/closing device is associated.
• Another purpose of this invention is to create an opening/closing device that is still simple from a structural point of view and, therefore, simple and economical to manufacture.
• an opening/closing device for a container for pourable products having at least one perforate portion
• said opening/closing device comprising a collar combinable with said container at said perforate portion, a cap constrainedly movable by first guiding means, which are interposed between said cap and said collar and a cutting element constrainedly movable by second guiding means, which are interposed between said cutting element and said collar, inside said collar for severing said perforate portion
• said device further comprising pushing means for said cutting element, which are actuated by said cap during at least its first displacement on said outer surface of said collar, for promoting the displacement inside said collar of said at least one cutting element in the direction of said perforate portion
• said cap is provided with at least one through hole for pouring said pourable product and with at least one lid integrally constrained to said cap and adapted to seal, or open, the passage of said at least one through hole, said first guiding means only rotatably constraining said cap to said collar, and characterized
• the rotation of the cap with respect to the collar is limited between two distinct positions: a first position, the one of the end of the assembly of the opening/closing device, that is, with the collar, cap and cutting element coupled together by pressure; and a second position, in which the cap is clamped at an angle in a position that prevents the cutting element from completely cutting the perforate portion, thus causing it to fall into the container.
• This also has the effect of ensuring that, when the cap is open, the pouring can be done at the side of the container closest to the collar and, therefore, it is easier for the user to pour the product in the container.
• this pouring takes place with the collar locked in a stable position, namely at the second position. In this way, the user will not have to worry about keeping the cap in a precise angular position with respect to the collar, but will be able to make the pouring in peace.
• such limiting means shall comprise at least two mutually binding parts attached to the cap and the collar respectively.
• such limiting means shall include at least one locking tooth engaging in at least one corresponding seat, in which at least one locking tooth protrudes inside that cap and at least one seat is defined on that outer surface of that collar, or vice versa.
• this locking element engages with this seat in such a way that it no longer rotates with respect to the collar.
• the angular interval between said first position and said second position is between 180 and 360°. This prevents the cutting element from completely cutting off the perforate portion with the result that the perforated portion falls into the container.
• said first guiding means comprise a first protruding radial portion and a second protruding radial portion, wherein said first protruding portion is integral to the external surface of said collar and said second protruding portion is integral to the internal surface of said cap and capable of crawling on said first protruding portion during the rotation of said cap with respect to said collar.
• Said first protruding portion and/or said second protruding portion shall be elastically deformable at least when said cap is associated with said collar during the assembly of said opening/closing device.
• the second protruding portion serves as a guide in the rotation of the cap on the external surface of the casting and at the same time prevents the cap from slipping out of the collar because the first portion is always in contact with the second portion.
• the opening/closing device shall comprise a safety ring which is firmly attached to the lower end of said cap by means of a number of breakable bridges; said breakable bridges shall be severed at least when said cap is moved, or rotated, from said first assembly position for said opening/closing device to reach said second locking position.
• said lid is made in one piece with said cap.
• the cap includes a pouring spout.
• the through-hole is made on the upper surface of the pouring spout.
• that lid is hinged to that cap by means of a plastic hinge associated with the lateral surface of that cap.
• said plastic hinge shall be placed on this side surface in such an angular position that, at least when this cap is in its second locking position, this lid, when opened, is on the side of the container opposite to the nearest side or sides of pouring.
• step b) causing, during said step a), the displacement of said cutting element in the direction of said perforate portion of said container for severing it; said method further comprising subsequently to said step b), the step c) of raising said lid integral with said cap for pouring the product contained in said container, characterized that the method further comprises the step d) of limiting the displacement of said cap between a first assembled position for said opening/closing device and a second locked position of said cap to said collar.
• said phase a) comprises phase a1 ) of rotating the cap in relation to the outer surface of the collar between that first position and that second position.
• the angular interval between said first position and said second position is between 180 and 360°.
• step c) includes the step of rotating the lid_with respect to the cap.

• the second guiding means 60 are of the screw 61 type and the nut 62 type, in which the screw 61 is attached to the cutting element 5 and the nut 62 is attached to the collar 2.
• the opening/closing device 1 is made of plastic material such as, for example, polypropylene. Other plastic materials can be used for the realization of the device 1 without departing from the scope of protection of the present invention.
• Collar 2 also includes a flange 30 that surrounds the entire perforable portion 101 of the container 100 and that, from its lower side 30a, is associated with the 100 container for gluing.
• the annular-shaped cutting element 5 has at its end 5a a plurality of teeth 5b to facilitate the breakage of the perforable portion 101 .
• the opening/closing device 1 also includes pushing means 7 for cutting member 5 actuated by cap 3, during at least its first movement on the outer surface 2a of collar 2, to promote the movement inside the collar 2 of cutting member 5 in the direction of the perforable portion 101 .
• These pushing means 7 are made of in one piece with cap 3.
• the cutting element 5 is forced by means of the pushing means 7 to move in the direction of the perforable portion 101 to cut it at least partially.

• device 1 also includes means 1 1 to limit the rotation of cap 3 with respect to the outer surface 2a of collar 2 between a first assembly position P1 for opening/closing device 1 and a second position P2 for locking the cap to collar 2.
• P1 position which is the initial assembly position of device 1 at the exit of the production plant, until it reaches a second locking position to the collar 2.
• the angular range between the first position P1 and the second position P2 is comprised between 180 and 360°. In the form described here, the rotation interval is 355°.
• such a solution allows the lid 10 to open in such a position that the product contained in the container 100 is easily poured into the collar 2 at the second locking position P2 of the cap 3. Moreover, the user does not have to worry about keeping the cap 3 in a precise angular position to allow it to be poured as it is locked in a fixed position with respect to the collar 2.
• the first guide vehicles 40 comprise a first protruding radial portion 41 and a second protruding radial portion 42, in which the first protruding portion 41 is attached to the outer surface 2a of collar 2 and the second protruding portion 42 is attached to the inner lateral surface 3b of cap 3 and is suitable for sliding on the first protruding portion 41 during the rotation of cap 3 with respect to collar 2.
• the first protruding portion 41 is also slightly elastically deformable at least when cap 3 is associated with collar 2 during the assembly of the opening/closing device 1 , thus allowing the association of cap 3 with collar 2.

• Cap 3 has a pouring nozzle 31 that juts out from the top surface 3a of cap 3 itself.
• the through-hole 32 is made on the upper surface of the pouring nozzle 31 .
• the diameter of the nozzle is smaller than the diameter of the upper surface 3a of cap 3, so that it is referred to as a kind of stepped surface 33 on cap 3.
• Lid 10 is hinged to cap 3 by a plastic hinge 35 associated with the outer lateral surface 3c of cap 3. In particular, the plastic hinge 35 is located right at the above-mentioned step 33.
• the pushing means 7 are arranged around the lower end section 31 a of the nozzle 31 and protrude axially from the upper surface 3a of the cap 3 into it.

• the lid 10 is located, once opened and the collar 3 has reached its second position P2, near the sides of the two faces 102 and 103, it would be difficult for the user to be able to pour the product contained in the container 100 especially at the beginning, when the container 100 is full. In fact, the same lid 10 would hinder the pouring of the product from the side or sides closest to collar 2 (in the example shown by the sides where the faces 103 and 102 closest to collar 2 are located).
• the method for the first opening of a 100 container for pourable products equipped with an opening/closing device 1 of the type described above includes the phases of:

• the method also includes step d) to limit the rotation of cap 3 between the first assembly position P1 for opening/closing device 1 and a second locking position P2 of cap 3 to collar 2.
• the displacement of the cutting element 5 in the direction of the perforate portion 101 of the container 100 is a roto-translation caused by the second guiding means 60 by means of screw 61 and screw nut 62 integral with, respectively, to the cutting element 5 and to the collar 2.
• Step c) includes the step of rotating the lid 10 with respect to cap 3.
