Definitions
- the invention relates to a method of manufacturing a plug of the type comprising a cover comprising a cylindrical ferrule intended to be engaged in the bottom of the container and a peripheral gripping edge to which is assembled a skirt in which is fitted a thread screwable on that ass.
- the cover is made of cork or synthetic material and the skirt belongs to an overcaping capsule, generally made of aluminum, initially smooth and in which the thread is formed by knurling after it has been placed on the butt previously blocked by the operculum, the collar then serving as a punch.
- the closure method employs complex means and is therefore expensive.
- the present invention provides a method of manufacturing such screw caps according to claim 1. Starting from the technique consisting of heat shrinking a section of sheath on a threaded neck, this method makes it possible to obtain regular threads on the cap.
- This process consists, before placing the sheath section on the container, to produce by a first heat-shrinking on a mandrel, a preform comprising, in its part which must subsequently come opposite the threaded zone of the neck, a corrugated zone projecting outside and whose developed length corresponding substantially to the developed length of said threaded area.
- the sheath section is preformed to present locally and longitudinally a reserve of material allowing, in the subsequent heat-shrinking phase, to fully conform to the profile of the turns of the net, therefore to form a regular net despite the unidirectionality. of the shrinkage of the material.
- This preform can be produced before deposition on the container closed by the cover or at the same time as it is linked to the cover to form an assembly which can be subsequently deposited on the container.
- the sheath section 4a instead of being delivered in the form of a cylindrical section having a square cross section with curvilinear sides, as shown in FIG. 1, is preformed to have the shape of the preform 20 shown at Figure 2.
- This preform 20 which has, in cross section, a circular shape with a diameter greater than the largest diameter of the neck d; container 2, so that it can be slid over this neck, locally has a corrugated area A.
- the preform 20 When the preform 20 is placed on the cuo of the container, it has, opposite the net of this container, an accumulation of material which, when this container is subjected to the heat-shrinking operation, allows it to perfectly match the contours of the net, despite the unidirectionality of the shrinkage of the sheath.
- the upper part of the skirt covers the peripheral edge 6 of the cover 3, to which it is linked, while its central part perfectly matches the contours of the container, thus forming a regular net ensuring a good connection with the container and which can be reused without problem when filling it.
- the container has, at the lower part of its neck 2, a shoulder 22.
- FIG. 5 denotes a training station and of distribution of sheath sections carrying means 27 distributing the sections 4a by spacing them relative to each other.
- a well-known device is, for example, of the type described in French patent 2,503,689.
- This device comprises an endless conveyor 28, the upper strand moving in the direction of arrow 29, goes from the distribution station 7 to a heat-shrinking tunnel 32.
- the lower strand of the conveyor moves in opposite direction to a station 30 for ejecting the preforms 20.
- the conveyor belt is integral with mandrels 33 projecting outwards perpendicularly to it. These mandrels are regularly spaced from one another and are capable of receiving a section of sheath 4a, delivered by the distribution station 27.
- each mandrel is composed of a barrel 34, a central core 35, a sleeve 36 slidably mounted in the annular space 37 formed between the core and the barrel and an outer ring 38 slidably mounted on the barrel 34.
- the barrel is linked by its base 39, to the two notched belts 40 constituting the conveyor.
- the connection of the base with each of the belts is ensured by a transverse pin 41 being housed in the gap between teeth of the corresponding belt so as not to stiffen the belt and allow it to marry the return toothed pulleys.
- the core 35 is tubular and is linked to the barrel 34 by a transverse pin 42.
- a head 43 which is in the extension of the barrel 34, having the same diameter as it, is spaced from this barrel to form a housing 44 in which are arranged two annular springs 45.
- the radial displacement necessary to make them protrude from the mandrel 33 is provided by the sleeve 36 whose free end is bevelled 36a and the lower end of which is provided with one and preferably with two fingers 46 passing through the barrel by oblong slots 47.
- the sliding ring 38 is integral with a stud 49 which, arranged transversely in a through hole 50 of the barrel 34, is subjected to the action of a re return spring 52 disposed in an axial housing 53 of the core 35.
- This ring 38 is therefore constantly urged by the spring to occupy the position shown in FIG. 6, corresponding to its position for positioning the gain section 4a. It has bearing surfaces 54 able to cooperate with ramps 55 represented schematically by the dashed line in FIG. 5.
- the heat shrink tunnel 32 is fixed on a mobile support 56 which is connected to a fixed support 57, linked to the chassis of the device, by means 58, such as jacks, capable of vertically moving the support 56 to bring it into an erasing position as soon as the conveyor 28 is stopped.
- the heat-shrinking tunnel is linked by a flexible pipe 60 to a hot air blower 62.
- means are provided on the conveyor 24 for synchronizing, in the preform ejection zone, the containers 23 with the mandrels 33
- the means consist of longitudinal screws 63, the pitch of the turns of which corresponds to the interval between containers and between mandrels 33.
- each sheath section 4a delivered by the dispensing means 27, is taken up by a mandrel 33 passing under this dispensing station, mandrel whose springs 45 are then retracted. As it advances, the mandrel comes in the vicinity of the ramps 48 which control the extraction of the springs 45. These thus come into contact with the wall of the section.
- the heat supplied by this tunnel ensures the retraction of the section on the barrel 34 and the head 43 and the formation of two beads constituting the ringed area A.
- each container 23 with the preform 20 passes through a heat-shrinking tunnel 65 ensuring the retraction of the preform from the threaded part of the container.
- This device can be used to form either preforms alone, linked to the covers during the final retraction, or assemblies composed of the cover 3 and the preform 20 in order to form capsules which can be dispensed later on the container necks.
- the head 43 of each of the mandrels comprises a housing for receiving and positioning a cover 3 and the device comprises a cover distributor arranged upstream of the distributor 27 of sheath sections.
