As soon as it is closed, it becomes a "bottle-torch" , with the following advantages: a) - These devices can be used interchangeably with capacities obtained by injection-blowing, extrusion-blowing, in plasticized, metallic cardboard, as well as in glass.
- Certain components of the molds, in contact with the injected material, may be coated with a non-stick material such as, for example, Polyetetrafluoroethylene, according to its French Patent No. 1,505,492 of January 15, 1963.

- the mold C facing shells, receives the female mold 7 raised from its low position, while the mold D is at pause 3.
- the female mold 7 returns to its low position, but with the "suction straw", to allow the shells 5 and 5 'of the mold C which have a part to be inserted into the female mold 7 to not no longer be in confrontation While for these same molds C and D in the same position, but for "a suction straw” for carbonated drinks, it is first necessary that the shells 5 and 5 'cease their confrontation to be able to bring the mold female 7 in its low position with the "suction straw”; some elements used for injection may be coated with a non-stick material. Merry-go-round ONE. Phase 2
- This simultaneous translation allows the female mold 7 of the carousel DEUX in stationary position at pause 1, still with the "suction straw” , go back to the high position and enter the mold A of "one-piece closure", limited by the confrontation of its upper end face, with the lower end face of mold A of the ride UN, which allows from the fixed station injection located in its rotation area, inject plastic through the horizontal injection point 13a, through the hole obtained in the skirt, around the projecting orifice, of the rectilinear cannula which constitutes the horizontal injection point (13a), which is no longer blocked, from the start of the male mold 7a.

- mold A it leaves pause 3 to come to break 4 where its shells open to release the "one-piece closure - suction straw” assembly to direct it by a translation device (not shown) to the packaging and closing stations with the protections of hygiene which are essential and which are multiple and known.
- the applicant takes account of the longest injection cycle, so that the speeds of rotation of the rides which may be different, make the breaks in the molds A and B, during their injection collaboration with the male mold 7a, or the female mold 7, as well as for horizontal injection.

- the tubing 16 is extended by the tubing 16a which arrive very close to the bottom 14b, forming together, the suction straw of the device "Monoblock closure- Suction straw” by specifying that this straw can be, depending on the material used, longitudinally larger than the interior of the capacitor which gives the tubing (16a) a certain suppleness and flexibility, to be able, by giving it longitudinally the possibility of bending, to arrive in the periphery of the bottom of the capacitor (14) in any material, or even to be able to deviate on an internal curved bottom from a plastic capacitor, and or even a glass capacitor, having an internal curved bottom, which allows at the same time and if necessary, being able to make the "monoblock closure" penetrate externally into this type of capacitor with
- FIG. 24 shows schematically and in elevation, a closure capsule (20) with its styling part 4, of a known type, with a skirt 3 having a circular line of reduced thickness (19), the skirt (3) can have only on its internal face a spiral thread, and can also have its two faces spiral threaded face, characterized to comprise two or four vertical and projecting edges, arranged at 180 ° if they are ea number of two, and at 90 ° if there are four, obtained by injection at the same time that all of this closure capsule 20, according to the same technique as those used to obtain the projecting edges on the removable cap (3) of a "one-piece closure".
