Definitions

• This presentation relates to an opening device with integrated straw for a container capable of containing a liquid, for example a container of the food can type, as well as such a container equipped with such a device and a method of manufacture of such a device and container.
• a food can comprises a border closed by a lid crimped on said border, an opening zone formed on said lid, and a push ring that a consumer actuates to cut out the opening zone and thus be able to drink the beverage contained in the can through this opening.
• the cans are handled several times and stored, for a more or less long period, in places of all kinds between their leaving the factory and their release for consumption. This results in an accumulation of various and varied bacteriological agents on the top of the can, which come into contact with the mouth of the consumer, when the latter is drinking the contents. There is a real risk of bacteriological or viral transmission for the consumer.
• the cans often contain sugary drinks which can attract, in the hot or humid season, when they have been opened, mosquitoes, flies, bees and other wasps. Without the consumer noticing, bees or wasps can therefore enter a opened can and dangerously sting the consumer, inside his oral cavity, and thus cause serious incidents.
• a first aspect of this presentation relates to an opening device for a container capable of containing a liquid, the device comprising:
• a lid configured to be crimped onto an edge of a body of the container so as to close the latter, the lid comprising a straw housing and an orifice adjacent to the straw housing,
• the terms "internal”, "external” and their derivatives relate to the container, in particular inside and outside the container, when the lid is crimped to the container. It is therefore understood that the outer straw is attached to the lid so as to extend outside the container, when the lid is crimped to the container.
• the orifice of the cover makes it possible to place the interior of the container in communication with the exterior.
• a user can drink the contents of the container through the outer straw, the latter communicating fluidly with the orifice, and therefore with the interior of the container when the lid is crimped to the container.
• the terms “upper”, “lower” and their derivatives refer to the orientation of the lid when the latter is crimped to the container.
• a lower face of the lid corresponds to the face of the lid oriented towards the inside of the container
• an upper face of the lid corresponds to the face of the lid oriented towards the outside of the container.
• the outer straw is made of an elastomeric material, preferably with shape memory, such as silicone.
• the term “straight position” of the outer straw is understood to mean a vertical position when the lid is crimped to the container, or a position in which the straw extends in a direction perpendicular to the plane in which the lid extends. This upright position is the position allowing a user to consume the contents of the container by sucking in the straw, and corresponds to a “natural” or original position of the straw, in the absence of any deformation.
• the slide is an opening/closing slide coupled to the lid, and therefore integral with the lid but able to slide relative to the latter, in order to allow the opening and closing of the device.
• the slide is attached to the lid in such a way that it cannot be detached from the lid, but it can move relative to it while remaining in a plane parallel to the lid.
• the closed position is the position in which the slide completely covers the straw housing and the orifice.
• the straw housing and the orifice are thus isolated from the outside.
• the straw external is also covered by the slide, and is kept folded by the latter in the straw housing.
• This configuration also makes it possible to isolate the straw from the external environment, before the container is opened for consumption, or even when the user does not wish to immediately drink the entire contents of the container. In the latter case, the consumer can temporarily close the container, for example for several hours. Consequently, insects such as bees cannot land on the straw or enter the container thus closed, so that consumer safety is significantly improved.
• the consumer can close the device by sliding the slide in the opposite direction, into its closed position.
• the slide In its movement from the open position to the closed position, the slide carries the outer straw, folding it into the straw housing.
• this device allows a consumer to drink the contents of a container by sucking through the external straw, without direct contact with the container, the straw itself being able to be isolated from the outside when the user does not consume the contents of the container.
• This configuration improves hygiene and reduces the risk of bacteriological or viral transmission.
• the opening device comprises an integrated elastomeric straw, the latter being fixed to the lid.
• a bottom of the straw housing includes a vacuum vent passing through the lid.
• the straw housing can be a recess in the lid, directed towards the inside of the container when the lid is crimped to the container.
• the vacuum vent allows the inside of the container to communicate with the outside, when the slide is in the open position. This vent acts as a vacuum hole allowing air to pass through when a consumer sucks the contents of the container through the outer straw.
• the slide comprises on one of its faces at least one protrusion capable of crushing the external straw by elastic deformation against the bottom of the straw housing so as to block the vacuum vent, when the slide is in the closed position.
• the protuberance extends from an underside of the slide towards the bottom of the straw housing.
• the outer straw is not only kept folded up in the straw housing, but also crushed in the bottom of the housing by the protuberance.
• the protuberance exerts a force on the straw allowing the latter to be pressed against the bottom of the housing, in which the vacuum vent is formed.
• the device also comprises an internal straw fixed to the lid so as to communicate with the orifice of the lid and with the external straw, and being able to be placed inside the container when the lid is crimped to said container.
• the internal straw extends from an underside of the lid towards the inside of the container.
• the inner straw and the outer straw are both hermetically attached to the lid, facing the hole in the lid.
• the inner straw preferably extends to a vicinity of the bottom of the container, thus allowing a consumer to easily drink the entire contents of the container, by sucking through the outer straw.
• one end of the slide is configured to come into abutment against the outer straw when passing from the open position to the closed position so as to fold the latter into the straw housing , said end comprising a guide notch of complementary shape to the outer straw and being capable of receiving the outer straw when passing from the open position to the closed position.
• the notch has a curved shape, for example in a semicircle, so that the straw is lodged in the notch when the end of the slide comes into abutment against the outer straw.
• This notch makes it possible to hold the straw laterally when it is folded down into the straw housing.
• the guide notch thus makes it possible to guide the straw while folding it, allowing it to be stored appropriately in the straw housing.
• the cover is an intermediate cover, the device further comprising an upper cover fixed to the intermediate cover and comprising a window arranged vis-à-vis the straw housing, the slide being arranged between the middle cover and the top cover.
• the upper cover can be fixed to the upper face of the intermediate cover, for example by welding.
• the assembly thus forms a double wall between which the slide is located, and between which the latter can slide to go from the open position to the closed position, and vice versa.
• the window is arranged vis-à-vis the straw housing so that in the open position, the presence of the window of the upper cover allows the deployment of the straw in its upright position.
• the upper cover constitutes a simple means of holding the slideway secured to the intermediate cover, while allowing the latter to slide between the intermediate cover and the upper cover.
• the upper cover comprises a hole adjacent to the window and arranged opposite a receptacle of the intermediate cover
• the slider comprises a safety stud connected to a main body of the slide by means of a junction so that, in the closed position, the safety stud protrudes outwards through the hole in the upper cover, and that when passing from the closed position to the open position, the junction is configured to break, the safety stud then falling into the receptacle of the intermediate cover.
• the receptacle may be a local recess of the intermediate cover, adjacent to the straw housing.
• the safety stud may have a substantially cylindrical or frustoconical shape, of which at least one upper end protrudes outside the hole in the upper cover. The safety stud thus makes it possible to hinder the movement of the slide towards the open position. It is necessary to exert on the means of gripping the slide, a sufficient force in the direction of opening, to allow the breakage of the junction between the safety stud and the slide, and thus the opening of the slide. In doing so, the safety stud moves from a high position, in which it protrudes out of the hole, to a low position after the breakage of the junction, in which it falls by gravity into the receptacle of the intermediate cover.
• the safety stud thus constitutes a safety device making it possible to limit undesired openings of the slide, before the first use of the device, in particular during transport or storage of the containers.
• the low position of the safety stud makes it possible to indicate that the device has been opened at least once.
• the safety stud has a frustoconical shape, one end of larger diameter of the safety stud having a larger diameter than the diameter of the hole in the top cover.
• a larger diameter end is arranged on a lower side of the hole in the upper cover, and the smaller diameter end is arranged on an upper side of said hole.
• the diameter of the end of the larger diameter stud being greater than the diameter of the hole in the upper cover, the safety stud cannot therefore escape through the hole, even when the junction between the stud and the slide is broken, and even when the container is turned upside down. This makes it possible to further limit the production of waste, in particular the rejection of small plastic elements, thus limiting the impact on the environment.
• the outer straw and the inner straw each include a base and a main body extending from the base, the base of the inner straw being attached to the cover, the base of the outer straw being interposed between the base of the inner straw and the lid.
• the base of the internal straw can be fixed to the underside of the lid, for example by riveting/riveting.
• the base of the outer straw is also attached to the underside of the lid by being sandwiched between the base of the inner straw and the lid. In this configuration, the body of the outer straw extends from its base outward through the hole in the lid.
• the fact of inserting the base of the external straw between the base of the internal straw and the lid makes it possible to compress this one.
• the base of the outer straw also made of elastomer, thus acts as a seal to improve the seal of the device.
• the slide has an arcuate shape and is capable of passing from the closed position to the open position by rotation.
• the opening device being preferably used on cylindrical containers of the can type, this shape of the arcuate slide is particularly suitable, and provides the movement necessary for deployment. of the outer straw when passing from the closed position to the open position.

• the slide After the manufacture of the opening device 1, and before the first use thereof, that is to say before the first opening of the slide 20, the slide is in the closed position. In this position, the safety stud 28 protrudes outward, passing through the hole 44 of the upper cover 40, the hole 44 being arranged opposite the receptacle 15 of the intermediate cover 10 (FIGS. 7A and 8A). The fact that the security stud 28 is visible projecting above the top cover 40 indicates to the consumer that the device has never been opened.
• the lower base of the safety stud 28 has a diameter substantially greater than the diameter of the hole 44. This prevents the safety stud 28 from exiting through the hole 44, when the safety stud 28 is detached from the rest of the slide, and the container is placed upside down for example.
• the manufacture of the container 100 initially comprises the manufacture of the opening device 1 (step S100), then the attachment of the opening device 100 to a container body 2 (step S200).
• the manufacture of the opening device 1 firstly comprises the assembly of the various elements described above with reference to Figure 3. More specifically, the outer straw 30 is first assembled to the intermediate cover 10 , by inserting the main portion 31 into the orifice 14 of the intermediate cover, from the underside of the latter (step S110). This assembly is carried out in such a way that the riveting pins 19 fit into the holes 33 of the base 32 of the outer straw 30.

More specifically, an edge of the underside of the main body 41 of the upper cover 40 is fixed to the edge 17 of the intermediate cover 10, for example by spot welding or welding bead. In addition to the border 17, the upper cover can also be welded by its central part to the central portion 11b of the intermediate cover 10.
• the upper cover 40 is arranged so that the window 42 is opposite of the main body 21 of the slide 20, the gripping means 24 passing through the window 42, and that the safety stud 28 is engaged in the hole 44 (FIG. 9E).

More specifically, Figures 11A and 11B illustrate in detail an upper end of the side wall 2c of the container body 2. Initially, this upper end comprises a border 2a, then unfolded ( Figure 11A). The opening device 1 is arranged on the upper end of the container body 2, of so that the border 11 of the intermediate cover 10, also unfolded, rests on the border 2a of the container body 2 (step S210).

It is thus possible to stack two or more containers 100 on top of each other, by fitting the bottom 2b of the container body 2 onto the upper end of another container 100, in the same way as conventional cans (figure 12). This interlocking is also facilitated by the curved shape of the bottom 2b of the container body 2.
