This can be arranged in suspension from the side flanges, or be directly on the drum.
• the spool of wiping material which is mounted on the support flanges (4) is tightly wound on a support mandrel (7).
• the latter receives, at at least one of its ends, a tip (8) which will be able to be positioned on the flange (4) of the casing opposite, the other end of the mandrel coming to be positioned on the flange facing arranged with a receiving surface (9) shaped during molding or arranged on a flexible tongue (10) articulated with respect to its support flange (4).
• These endpieces are generally made in cylindrical form with a transverse overflow flange bearing against the opposite face of the mandrel and the spool, an inner cylindrical portion being forcibly engaged in the mandrel, the endpiece having, in addition, and in the front, an appendage in axial extension being fixed in a notch of the support flange considered.
• the tip has a simple rectilinear appendage, or it may have, in the length of said appendix, a head end and a cylindrical bearing adjacent to the collar. It may also comprise a recessed area forming a groove and guiding path as illustrated in FIG. 2.
• said end piece is made to cooperate with a hinged guide (11) attached to the support flange (4) carrying a spool and facilitating the introduction of the coil of wiping material and its retention by displacement of the guide against an elastic means of return not shown.
• the support guide has projections (l ia) formed internally on the walls of its opening passage and introduction of the tip.
• the mandrel receives a single endpiece disposed at one end and cooperating with the aforementioned support flange, while the other end of the mandrel is centered on a bearing formed on the flange opposite.
• the arrangement of the opposite recesses allows the tilting of the mandrel down when the reel of material is exhausted.
• the mandrel and the end-mounted tip are recoverable and may or may not be reused or discarded, but without any change in the appearance and characteristics of the mandrel and bits.
• the problem posed is that of the reuse of the tips by competing persons or competitors who can be made to recondition them on mandrels with wiping coils not coming from the original prescribers of the wiping material distribution apparatus concerned. .
• the solution provided by the applicant aims to make unusable the endpiece considered after finishing the coil, by the competition and for himself as well.
• the applicant's solution is, to say the least, unexpected and is the opposite of conventional objectives in the industrialization of products, and environmental demands for waste.
• the solution devised by the applicant applies to any type of wipe material dispensing apparatus which uses at least one nozzle inserted into the support mandrel of the wiping material coil.
• the tip for a spool of wiping material of the type comprising a cylindrical bearing, tightly fitted in the mandrel support of the spool, with a transverse bearing flange overflowing the cylindrical bearing surface and bearing on the facing face of the mandrel and the coil, and an axially extending appendix having a head with an inner hole and a recessed section forming a guide groove, said recessed section being disposed between the end head and a cylindrical bearing adjacent to the collar, said tip being remarkable in that, the head of the axial appendix and a portion of the grooved recess section constituting the guide path, are deformable and arranged internally with a brittle hole for crushing their deformation during the extraction of the mandrel and the tip of the receiver flange, and in that after extraction of the mandrel and its tip, the head of said tip is in the final state permanently deformed and non-reusable.
• FIG. 1 is an exemplary view of a wipe material dispensing apparatus with a coil to be suspended relative to the drum, the coil being disposed on a receiving mandrel of at least one endpiece.
• FIG. 2 is a partial view in perspective of a shaped tip cooperating with an articulated guide mounted on the flange of the device.
• FIG. 3 Figures 3, 4 and 5 are schematic views illustrating the positioning of the nozzle according to the invention in the support guide.
• FIG. 6 is a longitudinal sectional view showing the nozzle according to the invention mounted on the support guide in the use phase.
• FIG. 7 is a front view of the nozzle in the situation of FIG.
• FIG. 8 is a longitudinal sectional view illustrating the tilting of the mandrel for extraction.
• FIG. 9 is a view complementary to Figure 8 illustrating the extraction phase of the mandrel and its tip and thus the deformation of the latter.
• FIG. 10 is a front view of the nozzle after deformation of the head.
• FIG. 11 is an alternative view of the head of the tip which has in its thickness a primer of fragility.

• - Figure 13 is a sectional view along the line A.A of Figure 12.
• FIG. 14 is a partial exploded view before mounting the tip on a support flap mounted on the support flange of the wiper material coil of the device.
• FIG. 15 and 16 show the mounting of the nozzle according to Figure 12 in said flap ensuring its locking in position.
• the tip (12) has a cylindrical surface (12a) with projections (12b) and a transverse flange (12c) to engage tight fit into the mandrel.
• This area of the tip which is intended to be in the mandrel can be arranged differently, that illustrated in the figures of the drawings being simply by way of example.
• the front part of the end piece that is to say located outside the mandrel, presents from the transverse flange, an axial appendage comprising a conical seat (12d) extended by a cylindrical seat (12e), a head (12f) at the end and, in between, a grooved recess section (12g) for forming a guide path.
• the presence or absence of the conical portion (12d) depends on the configuration of the tip.
• the head (12f) and the recessed section (12g) grooving the tip (10) are deformable and are arranged internally with a hole (12h) of fragility whose function will be to allow as a result crushing the deformation of at least said head and if necessary the recessed section during the extraction force of the mandrel after closing the coil.
• This deformation is enabled by the flexibility of the constituent material of the tip, and thus the diameter and the depth of the blind through hole thus executed.
• the guide (11) illustrated in FIG. 2 or FIGS. 6, 7, 9 is thus arranged with a slot for introducing the endpiece with a protruding zone corresponding to the recessed section (12g) of the end piece to ensure its guidance. It defines in a way a form in constriction and the rear part of the head (12f) of the tip abuts against the inner wall of said projecting zone.
• the endpiece In the normal situation in FIGS. 5 and 6, in the presence of material on the mandrel of the spool, the endpiece has perfectly retained the recessed portion being centered around the projecting zone of the guide.
• a tongue (1 Ib) resilient deformation integral with the guide maintains the tip in position and prevents its withdrawal.
• the tip of the mandrel can no longer be used by its deformation of the front part answering the problem.
• the deformation obtained from the head of the nozzle and thus its recessed section does not generate any risk of breakage or rupture of the head relative to the body of the nozzle, so that there is no detritus that may remain in the dispensing apparatus.
• the head of the tip on its front face has partially in its thickness a cross-shaped (12m) to facilitate the folding and deformation of the head of the tip and constituting a primer. fragility.
• the references of the deformable tip are the same, with the exception that the recessed section (12g) is of very particular configuration. It has indeed two opposite contractions (12gl) of curved shape which reduce the thickness of the section (dl) of the order of 1.5 to 2 mm, while the section (d2) in the other perpendicular plane is of the order of 3 to 4 mm.
• this arrangement offers a specific advantage in locking the tip.
• the tip with deformable head can be used with a device represented in FIGS. 14, 15 and 16.
• One of the flanges (13) receiver of the spool mandrel is arranged in its inner part with a seat shape (13a) delimited by a peripheral contour corresponding to the shape of a support piece (14) in the form of flap, and having cradles (13b). ) receivers articulation axes (14a) of said flap.

• the flap support member (14) has a guide path (14b) defined by an oblong slot (14c) established in its thickness with longitudinal ribs (14d) forming guide rails.
• the rear face (14e) has a recess (14f) forming a seat of a spring (15) which bears on the opposite side of the flange.
• the particular configuration of the nozzle, according to FIGS. 12 and 13, makes it possible to cooperate with the aforementioned device with, in particular, a maximum narrowing of the distance between the guide ribs. between 1.5 and 2 cm, and allowing only one possible direction of introduction of the tip according to its section (dl) in view of its different section (d2) in one plane relative to the other.
• pins (12i) in the form of projections or other, can be established on the tip materializing the direction of introduction thereof into the flap support piece.
• the end of the oblong slot (14e) is arranged with a recess (14g) which corresponds to the profile of the head of the tip.
• This variant of implementation of the tip has a specific advantage given by the differentiated section of the recessed area (12g), which is intended to prevent, by the specific arrangement of the support piece shaped flap, any use of competitive tips which, thus, can not enter the aforementioned support part by their configuration and inappropriate section.
