Description

The present invention is in the field of

  capping the containers and its purpose is a plug, said

  absolutely inviolable, giving the buyer of the product contained in the receptacle the guarantee that the latter has not yet been opened; it relates more specifically to the screw cap. Screws are known which offer such a guarantee; such caps are generally made

  by a metal cap whose skirt has a screw thread

  sand on the thread of the container; after filling the bottle

  and screwing the plug, the peripheral and inferior edge of the

  pe is crimped around and below a circular flange protruding from the container; this lower edge which will constitute the ring

  guarantee is attached to the skirt by a breaking line

  killed by a dotted cut; during the first unclogging, the points of attachment will be broken by traction since, while the skirt will rise along the thread, the ring retained by the

  flange, will remain fixed in translation on the neck of the container.

  Such security capping systems have given proof of their interest in the closure of containers of consumer products, such as for example beer, fruit juices, especially gaseous, etc. ..; their cost is low and they have good airtightness; however, we can blame them for being difficult to unscrew for the first time because

  they offer little grip on the fingers; more applied to the boucha-

  In the case of containers treated in small series, such as containers for beauty products, they require, for each type of bottle, the assembly of crimping members which is expensive to implement; of

  more and always for this same application they are unattractive

c.

  The present invention aims to pro-

  install a machine-free, machine-crimp-free closure system, offering the possibility of a neat presentation and great diversity, and finally allowing a first

relatively easy opening.

  According to the invention, a plug of the type

  sand on a threaded neck, said stopper having an internally threaded skirt, at the base of which is attached along a break line a warranty part closed below a projecting portion of the neck, is mainly characterized in that said guarantee piece is constituted by at least one pivoting lug around the breaking line so that it can be folded down

  below the projection of the neck, by an external body

  moving along said skirt, for when in

  lower position, fold down said pin, and by. means to meet

  the outer body and the skirt are secured to one another

  that the outer body is in the low position, where it results mainly that said outer body being in the low position or guarantee, the first unscrewing will cause the rupture of

  This also results in the plug being

  by the manufacturer with his two bodies nested one in the other

  capping operations include first and foremost a

  simple screwing on the container and secondly the implementation of

  the means to render the ex-corps mutually supportive of one another

  inner and skirt; these means as they will be described later require in a simple manual or mechanical effort on

the outer body.

  According to a preferred form of said means

  aforementioned, these comprise guide means in transla-

  preventing the rotation of the skirt with respect to the body ex-

  inner and locking means in translation to prohibit the translation of the outer body relative to the skirt when the outer body is in the low position or guarantee; in this particular embodiment of said means, it is noted that the operation

  leading to the guarantee of closure consists of

  an additional translation that implements the

locking means in translation.

  According to a more specific form of

  embodiment of the invention in which the facing faces of the skirt and the outer body are substantially cylindrical, the translation guiding means are grooves according to the

  generators of said cylindrical faces, and the blocking means

  in translation are constituted by at least one groove and a

  rib respectively on the one and the other side, said grooves

  res and ribs being perpendicular to said generators. Note that this is a fairly general form of plug structure resulting from the fact that the threaded necks are necessary

  cylindrical; this cylindrical shape being found in the

  chon provides maximum material savings. However,

  imagine that, without departing from the scope of the invention, the outer face

  the skirt is, for example, square-base prismatic, and so are the inner faces of the outer body, it is clear that such shapes prohibit rotation.

  bodies in relation to each other.

  In a general way finally, we will note

  it is expected that said lug at least slightly exceeds

  below the lower edge of said outer body, from which it results

  that the guarantee of non-opening is apparent.

  The present invention will be better understood

  and details will arise from the description that will

  to be made in connection with the figures of the attached single plate, in which: in cutaway court of the corr they chage, Fig.1 is a schematic illustration e of the closure device of the invention, fig.2 is a ze representation of an outer body of an embodiment, Fig.3 is a similar representation s inner or plug proper of the same, fig.4 is a section of the same

  are assembled on a container to guarantee the

and

  Fig.5 is an illustration of a variation

  te means locking in translation.

  In Fig.1 a container neck 1 is provided in 2 with a thread and 3 of a projecting circular flange; it should be noted that, as indicated by the dots 4

  such a collar can be reduced to a circular base of the

thread.

  On this container neck is screwed a

  chon 5 which comprises a bottom 6, a skirt 7 internally threaded and a piece 8 in the form of tenons or organs attached to the base or

  lower rim or mouth of the skirt.

  Around the skirt 7 can be moved a

  outer body 9 surrounding the skirt.

  During the first uncorking, the external body

  laughter 9 occupies the position in chest 9 '; the member 8 itself substantially occupies the spaced apart position shown at 8 'chest. At the end of the closure the outer body is moved from 9 'to 9 and this displacement of the outer body comes to place the pin 8

below the collar 3.

  After this last operation means are then used to block the outer body in the latter position it occupies with respect to the skirt; therefore if the aforementioned means can not be unlocked very easily, for example without the aid of appropriate instruments, the unscrewing of the skirt will cause the breakpoint of the attachment point of

  the organ to the skirt and the latter will fall naturally.

  Attention must be drawn to the

  lift of the section of the point of attachment 10 which must be such

  a significant unscrewing effort is applied to the

  chon to allow the break of this point of attachment; this section

  depends, of course, on the material used, the number of

  points of attachment, of the screw of the neck, etc ...

  In fig.2 an external body 11 equiva-

  slow in its section to the body 9 of the previous figure has a

  cylindrical general me closed at its upper part; its inner face has grooves 12 on part of its height, grooves which merge with the generatrices of this face

  cylindrical interior and a pair of perpendicular grooves 13

  the generators referred to above, and therefore circular.

  In fig.3 an inner body or

  chon itself has a generally cylindrical shape closed in

  at its upper part; the side wall or skirt 16 is thin

  internally thrown in 17 at the thread of the container, and externally it comprises interpenetrating ribs 17 with

  the grooves 12 of the previous figure; it includes in the neighborhood

  swimming from its base a pair of circular ribs 18 also interpenetrable with the grooves 13 of the previous figure; the skirt finally has attached to its lower edge a plurality of lugs such as 19, 20, etc., each of them being attached to the skirt by two small fasteners, or break points, such as 21. It is visible that the inner body can be nested in the outer body is then recognized in the grooves and ribs 12 and 17 guiding means

  which make it possible to move in axial translation the external body

  In this embodiment, these translational guiding means are also rotational locking means of the outer body with respect to the skirt; we recognize in the grooves and

  ribs 13 and 18, respectively, blocking means in trans-

  which when they are engaged in each other

  except where considerable effort or appropriate means are

  axial placement of the cap relative to the plug; preferentially

  the capping device will be presented at the capping station

  with its plug encased in the cap, the ribs 18 do not

  not yet engaged in the grooves 13; it will be enough then after screwing to push the cap to force the

ribs 18 in the grooves 13.

  In fig.4 the position of the parts

  presented is a result of the aforementioned force transfer, we note

  that while organs such as 19 are engaged below

  the collar 22 of the bottle 23; therefore and as indicated before

  cedemment the unblocking will be able to be carried out only after rupture

  by pulling all the fasteners 21.

  We will notice on these last two

  gures that the upper part of the inner body is shaped in bowl 24; this arrangement has the advantage of preventing the air present before the guaranteed closing operation from being

  too compressed during this last operation.

  We will notice in fig.5 the shape to

  triangular section of a rib for example 25 and a reason

  Nure 26 constituting said translation locking means.

  It must be understood that the present

  tion is not limited to the above-mentioned forms of

  but it extends to any device of closure such

  as defined by the claims which follow.
