Abstract

METHOD FOR MANUFACTURING AN ACTIVE PRODUCT SUPPORT FOR A TOILET BOWL. THIS PROCESS CONSISTS OF REALIZING THE SUPPORT BY MOLDING TWO SEPARATE PIECES: on the one hand, THE SLITTED CAGE INSIDE WHICH THE STICK OF ACTIVE PRODUCT IS INTRODUCED AND, on the other hand, A MOLD ASSEMBLY OF ONE PIECE CONSISTING OF A SUSPENSION HOOK AND A CAGE CLOSING PLUG, THE CLOSING PLUG IS CONNECTED BY BREAKABLE FASTENERS COMING FROM THE MOLDING TO A CONNECTION RING ALLOWING THE HOOK TO BE FIXED AROUND THE CAGE. ALLOWS THE MANUFACTURE OF DEODORIZER AND DISINFECTANT SUPPORTS AT A LOW COST PRICE.

Description

It is known that to disinfect and deodorize the cuvettes of

  toilet, it has already been proposed to hang on the edge of those

  and a support obtained by assembling a perforated cage containing a baton of active product and an attached hook most often set up in the factory around the cage. The perforated cage, generally of cylindrical shape, can be closed at one of its ends by a bottom and open at its other end, after introduction of the batten premolded by its

  open end, the cage can be closed with a plug

  three separate pieces namely, the hook hook, the cage adds

  and the closure cap; then the assembly into two opera-

  the closure cap on the perforated cage after placing the premolded baton on the one hand and the

  suspension hook around the central part of the cage.

  To simplify the manufacture of the support and make it less expensive it has also been proposed, in particular in the French patent application filed July 7, 1978 under the number 78 20263 of

  mold in one piece the closure cap and the hook hook.

  carried, which makes it possible to reduce by one unit the number of separate elements constituting the support as well as the number of assembly operations, because a single operation is sufficient in this case to assen-ibler the cage to the whole suspension cap-hook. However,

  since the closure cap is attached to one of the ends

  of the cage while the suspension hook must be "in the central part of the cage, it is essential to

  provide a connection strip whose length is sensitive-

  Equally equal to half of the cage, the bar which connects the closure cap to the suspension hook in the case where it is desired to mold these two elements in one piece. Therefore, the gain realized

  the number of molding and assembly operations is

  This is affected by the increase in the amount of raw material needed to mold the terminal strip, which, moreover, has the disadvantage of increasing the external volume.

  finished support and the size of the sealed packaging

  fears under which it is conditioned before being put into the com-

  commerce. Added to this is the fact that a support of this kind can

  fictionnally ensure, under the action of the flushing water maintaining the cage, parallel to the edge of the toilet bowl on which it is suspended, because in this embodiment, the cage

2 2458739

  is attached to the hook by the end cap and is not

  therefore not supported in its central part.

  The present invention aims to propose a method of manufacturing

  Y 'tion of a support of the type mentioned above but not having iW5 no connection strip between the closure cap and the suspension hook, although these two elements are made

  in one piece by molding plastic material. According to the invention

  the suspension hook is secured to a connecting ring.

  which is intended to be threaded around the cage and fixed in the central part thereof. The closure cap is disposed inside the hook connecting ring where it is fixed by means of moldable breakable fasteners. The closure cap is provided at its periphery with hooking members

  which are intended to ensure its attachment by snapping on the former

  open end of the cage. Thus the operation of setting up

  the ring connecting the hook around the cage may be half

  takes advantage of shearing the breakable fasteners that connect the

  connection to the cap and to snap it onto

  the open end of the cage. As a result, in a single operation

  made in the factory on a suitable machine, the suspension hook and the closure cap can be assembled

the cage.

  The suspension hook has the conventional shape of a U but according to another characteristic of the invention the hook is connected to the connecting ring by a hinge consisting of a hinge from the molding. Upon demolding the ring is returned to the inside of the hook U and is held there by a breakable fastener from the molding. Until the moment of its implementation, that is to say until the user tears the sealed envelope in which is conditioned the support according to the invention,

  the connecting ring remains disposed inside the U-shaped

  chet. To suspend the support according to the invention on the rim of a toilet bowl, the user breaks the clip which connects the hook to the connecting ring so that the latter can

  by pivoting around its hinge be cleared out of the U of cro-

  chet. Thus, before use the hook is "folded" around the cage, which has the effect of significantly reducing the volume of the assembly cage-hook suspension and therefore dimensions

  the sealed envelope where it is conditioned.

  The present invention therefore relates to a method of manufacturing

  a support comprising on the one hand a perforated cage which

  holds a stick of active product for disinfection and

  deodorization of toilet bowls; and, on the other hand, a

  attached trunk secured with the openwork cage around the central area thereof to ensure the suspension on the rim

  of a bowl, the perforated cage being open at one of its ends.

  with a bottom at its other end, the end

  green of the cage being closed by a closing mouth, after

  by plastic molding the attached hook with the

  closing of the perforated cage, the suspension hook being connected to a connecting ring which is intended to be threaded around the perforated cage, then fixed around the central part of the latter, the closure cap being disposed at the the inside of the connecting ring and connected to said ring by breakable fasteners molded; that we introduce

central of this one.

  In a preferred embodiment, the connecting ring

  and the closure cap are substantially coaxial, the

  connecting piece protruding axially on at least one of its sides with respect to the closure cap so that, at the time when the closure cap bears substantially on the open end of the cage, the connecting ring is nested on said cage, while the breakable fasteners are not yet broken; the cage has at its open end a

  the essential importance of being made by molding two separate pieces

  Rees; on the one hand, a perforated cage 1 and, on the other hand, a suspension hook 2 integrally molded with the closure cap 3 of

the perforated cage 1.

  The pierced cage 1 is of cylindrical general shape: it

  has at one of its two extremities a bottom whose configuration

  identical to that of the closure cap 3. The cage is

  1 is open at the other end; the open end is bordered by a peripheral collar 4 on the inner wall of which is formed an annular groove 5. The side wall of the cage is

  formed of a plurality of identical bars 6 which are regularly

  spaced apart and which are each constituted by a lamella arranged in a radial plane; the bars 6 are connected to the end collar 4 of the cage and are interconnected in their part

  central by a ring 7 (Figure 3).

  The perforated cage 1, like the closure cap assembly 3-hook suspension.2, is made by molding a conventional plastic material, such as polyethylene or polypropylene

for example.

  The closure cap 3 is intended to engage with the

  bottom of the end collar 4 of the perforated cage. it is in the form of a seven-pointed star arranged inside a ring 8. A peripheral ratchet ring 9 is provided in relief

  on the outer wall of the aforementioned ring 8; fixing the

  3 on the perforated cage 1 is performed, when the closure cap 3 is detached from the suspension hook 2, by snapping the peripheral ring 9 of the plug inside the

  annular groove 5 made on the end collar 4 of the cage.

  In demolding, as is visible in Figures 1 and 2 lo of the drawing, the closure cap 3 is disposed within a connecting ring 10 allowing the introduction of the suspension hook 2 on the cage openwork.The connection ring 10 which

  must be threaded around the perforated cage 1, has an integral diameter

  At demolding (FIGS. 1 and 2) the closure cap 3 is

  P, held inside the connecting ring 10 by means of

  frangible spots or pins 12 provided on the end of each of the teeth 11 of the connecting ring 10.

  5 and the adjoining connecting ring 10 are substantially coaxial.

  The closure cap 3 is entirely arranged inside the connecting ring 10 so that the latter protrudes

  axially on both sides with respect to the closure cap 3.

  Thanks to this arrangement, the connecting ring ensures the central

  The closure plug is depressed in the opening of the neck of the cage when it snaps into the interior of the latter. Indeed,

  if the connecting ring 10 and the plug 3

  At the right of the opening of the cage, the connecting ring can be fitted around the cage before the fasteners 12 $ are broken. In this position, the axes of the closure cap 3 and the perforated cage 1 are substantially merged and it is therefore sufficient to apply an axial thrust force on the closure cap to, on the one hand, break the fasteners 12 and, on the other hand, snap the closure plug 3 inside the

end collar 4 of the cage.

  The suspension hook 2 has the shape of a U having two substantially parallel branches 2a, 2b, connecting to a

  soul 2c; the branch 2a of the hook is connected to the connecting ring

  10 by a hinge 13 coming from the molding. The ring of

  10 or the suspension hook 2 sCnt able to pivot around the hinge 13 along an axis substantially parallel to the axis of the connecting ring 10. The hinge 13 is formed between, on the one hand, a tab 14 provided in relief on the outside of the ring and, on the other hand, the end of the branch 2a of the hook, which

  is slightly bent towards the inside of the hook U.

  As can be seen in FIG. 1 of the drawing, the ring

  the connection 10 is, at demolding, substantially disposed of in the

  bottom of the hook U and it is held in this position by

  a frangible fastener 15 connecting said ring to the branch of extra-

miter 2b of the hook.

  The mounting of the support which has just been described can be done

  performed in one operation; after introducing a stick of

  disinfectant and deodorant product inside the cage.

  closing clan 3 contiguous to the right of the opening of the openwork cage 1, then the connecting ring 10 is wrapped around the cage until the breakable fasteners 12 come to bear

  against the end collar 4 of the cage; if we continue

  insertion of the connecting ring 10, it occurs

  -25 a break of the fasteners 12 so that by exerting then a po-

  sée against the closure cap 3 can snap it inside the end collar 4 of the cage. When the connecting ring 10 of the hook reaches the central zone of the cage, a pawl 16 provided on an inner tooth 11 of the ring

  10 is hooked under the wall of the central ring

  of the cage which ensures, therefore, the fixing of the

  connecting water 10 in the central part of the cage. This assembly operation is carried out without the breakable fastener 15 is broken so that, on the assembled support, the hook of

  suspension 2 retains its "folded" position.

  Conventionally, the support once mounted in the factory is

  placed under waterproof packaging for the purpose of being put on the market.

  At the time of implementation, the user tears the package and breaks the fastener 15 connecting the end branch 2b of the hook to the connecting ring 10; the cage and the connecting ring

  associates can then be taken out of the hook U by

  around the hinge 13 and until abutment of the lug 14 of the connecting ring on the extremity edge
