Abstract

THE INVENTION CONCERNS A SECURITY CAPSULE PROVIDED WITH A TAMPER BAND INTENDED FOR CONTAINERS PROVIDED WITH A SPOUT. THE CAPSULE INCLUDES A FIRST CYLINDRICAL ELEMENT 1 AND A SECOND CYLINDRICAL ELEMENT 2 WHICH ARE COUPLED ON THEIR LATERAL SURFACE BY MEANS OF TEETH 6 AND 7 AND ON THEIR UPPER PART BY MEANS OF BOSSES 8 AND 10; IT ALSO INCLUDES AN ANNULAR ELEMENT 3 CONSISTING OF A FIRST RING 5 WHICH SNAPS ON THE FIRST CYLINDRICAL ELEMENT, A SECOND RING 16 WHICH CONSTITUTES THE INVIOLABILITY BAND, AND AN ADDITIONAL ELEMENT 17 WHICH SEPARATES FROM THE ANNULAR ELEMENT 3 WHEN INSERTING THE CAPSULE ON THE CONTAINER.

Description

The present invention relates to a capsule of

  with a tamper-evident band intended for

containers with neck.

  Capsules of this type, which exist in several embodiments, must first of all make it possible to detect whether a first opening of the capsule has taken place so that the consumer can be saved against possible violations of the contents of the container. . These capsules must also provide protection against unwanted or unwanted gurgles, for example from children who could access the contents of the container which may be sometimes toxic or in any case dangerous. In general therefore we try to provide these capsules with means that do not allow

  opening only through the combination of several movements.

  The studies carried out for the implementation of these capsules aim to make the construction and assembly capsules more and more easy and economical and to allow their easy installation, by means of automatic machines, on the neck of the container which 'they are

designed to butcher.

  The object of the present invention is to make

  the development of these capsules, by developing a capsule which is provided with a tamper-evident band,

  These and other goals are achieved by the course

  a first cylindrical element constituting the true cap of the container; - 2 i - a second cylindrical element disposed coaxially on the first cylindrical member, which provides protection against unwanted openings; characterized in that - on the outer side wall of the first cylindrical member is formed a plurality of first teeth,

  arranged along the generators and one side of which is connected

  roped to the same outer wall, these teeth meshing with

  the plurality of first teeth so as to make the

  said first and second cylindrical elements integral with the rotation in the screwing direction of the capsule;

  the diameter of which is smaller than the diameter

  the smallest of the same annular element, which is coaxially connected to the annular element by breaking points, so that it can be easily

separate from the latter ..

  Other features and advantages of the invention

  will be more clearly apparent from the description

  of a preferred but not exclusive embodiment of

  sive of the capsule in question, given

  of non-limiting example with reference to the drawings

  nexés, in which: - Figure 1 shows a section in vertical elevation of the capsule in question; - Figure 2 shows a section executed along the line

  II-II of Figure 1, the capsule in question.

  The capsule which is the subject of the invention comprises a first

  first cylindrical element 1 constituting the true mouth of the container and which serves to close the container after making the first opening. Element 1

  is normally manufactured by plastic molding

  rather rigid and, in the form of

  shown in the figures, it is provided with an internal thread

  who marries an external thread normally provided

  on the neck of the container, which is standard type.

  On the outer side wall of element 1

  provided a plurality of first teeth 6 which are dis-

  placed along the generators and which have a rac-

  -4- strung to the same outer wall. On the outer upper wall of the element 1 is formed a plurality of first bosses 8 which are arranged radially on a

  circular crown. On this outer upper wall

  furthermore, a frustoconical protrusion 9 is provided which is arranged inside with respect to the bosses 8 and is

coaxial with element 1.

  The capsule is provided with a second cylindrical element

  2, also obtained by molding, made of plastic,

  which is arranged coaxially on the first element cy-

  lindrique so as to hood it.

  On the inner side wall of element 2 we have

  arranged a plurality of second teeth 7 which are

  along the generators and have one side connected to the same outer wall. The teeth 7 engage with the teeth 6 obtained on the element 1 and their arrangement is such that it gives rise, in combination with the teeth 6, to a kind of snap which, thanks to the connected sides of the teeth 6 and 7, allows the counter clockwise relative rotation between the element 2 and the element 1, while it prevents the relative rotation in the clockwise direction between the same two elements . In other words the presence of the teeth 6 and 7 allows the wetting (clockwise rotation) of the capsule on the neck of the container, but it prevents unscrewing (rotation in the opposite direction of the needles of a watch) because the connected ends of the teeth slide over each other and prevent rotation of the element 1 when

element 2 is turned.

  In order to facilitate the sliding of the sides of the teeth

  7 on the sides of the teeth 6, the side wall

  5 of the element 2 is provided, in correspondence with each of the teeth 7, with a portion of reduced thickness.

  relative to the thickness of the remaining portion of

  face. In this way the possibility of deformation

  elasticity of this portion is increased and doncrle glis

  The teeth 7 on the teeth 6 is facilitated.

  It should be noted that if one tries to open the container by simply turning the element 2, which for example could be done by a small child in the attempt to access the contents of the container, the return

  elastic portion of the reduced thickness portion, which is

  when the contact of the connected sides of the teeth 6 and 7 terminates, causes the teeth 7 to abut against the outer wall of the element 1, causing a noise that can serve as a sound signal of the attempt

opening of the container.

  On the upper inner wall of the element 2 there is a plurality of second bosses 10 which are arranged radially in a circular crown matched to the circular crown on which there is the first plurality of bosses 8. On this

  inner wall is also provided

  flexible ring 11 which is supported on the sail-

  9 when the element 2 is capped on the element 1. The height of the annular projection 11

  is such that it maintains the plurality of first

  8 is slightly separated from the plurality of second bosses 10. If the element 2 is rotated, the bosses 10

  do not interfere with bosses 8.

  On the contrary, if you exert a slight pressure

  above the element 2, the annular projection 11

  1. If we then turn the element 2 the bosses

  interact with the bosses 8, so that

  1 is made integral in rotation of the element 2, which therefore allows the unscrewing of the capsule

and therefore its opening.

  If we stop putting pressure on the part

  ring 11 again causes the separation between the upper wall of the element 2 and the upper wall

  of element 1 so that the interference between

  In order to facilitate the elastic deformation of the annular projection 11, a plurality of cuts 12 are provided which are arranged along the generatrices of the sail.

  Summarizing what was exposed above, the screwing of the capsule on the neck of the container takes place, thanks to the

  terference of teeth 6 and 7, even if one turns only

  in a clockwise direction the element 2 while unscrewing the capsule can not occur

  that by exerting a pressure on the capsule and in

  the element 2 in the counterclockwise direction since, in order for the unscrewing to occur, the bosses 10 must interfere with

bosses 8.

  The capsule in question further comprises an annular element 3 which in turn consists of a first

  ring 15, a second ring 16 and an additional element

17.

  Indeed, when introducing the capsule on the

  bottleneck of the container, the ring 16 comes to arrange

  underneath an annular element whose bottlenecks

  The additional element 17 has a smaller diameter than the smallest inner diameter of the annular element

  1; element 17 is connected coaxially to the element

of the container.
