FR2589828A1 - "CHILD PROOF" TYPE COVER WITH INVIOLABILITY BAND - Google Patents

Abstract

THE INVENTION RELATES TO A "CHILD PROOF" TYPE COVER WITH A TAPPING TAPE. IT INCLUDES AN INTERNAL CAPSULE 4 INTRODUCED REMOVABLE ON THE MOUTH OF THE CONTAINER 1 AND AN EXTERNAL CAPSULE 5 ARRANGED ON THE FIRST. THE EXTERIOR CAPSULE 5 IS ENGAGED WITH THE INTERNAL CAPSULE 4 SO THAT IT APPEARS FREE OR SOLID WITH THE latter ON ROTATION, DEPENDING ON THE RELATIVE AXIAL POSITION TAKEN. AN INVIOLABILITY BAND 12 IS ASSOCIATED WITH THE PERIPHERAL EDGE 11 OF THE MOUTH OF THE OUTER CAPSULE 5, THIS BAND ACTING AS A STOP WHEN IT COMES IN CONTACT WITH THE BODY OF THE CONTAINER 1 AND PREVENTS THE AXIAL DISPLACEMENT OF THE OUTER CAPSULE 5 IN RELATION TO THE INTERIOR 4, FROM ITS POSITION OF FREEDOM TO THAT OF SOLIDARIZATION TO ROTATION.

Description

The invention relates to a cover of the type "on the

  children's proof ", with a tamper-evident band.

  It is usefully used on all containers for which it is desired or expected that the opening can not be performed by children. Lids of the type known as "childproof" are already known in which the opening

  can be carried out only with the sequential execution

  this of coordinated movements that can be difficult

  performed by children below a certain age.

  These embodiments comprise an integral capsule

  provided with connecting means, normally of the type

  which allow the introduction of amo-

  on the mouth of the container to be closed, and a cap-

  outer shell (capsule cover) which "covers" the cap-

  interior of which she is disposed. The cap

  outer sule is engaged to the inner capsule of

  in such a way that the conditions

  freedom of rotation (safety condition

  or "child proof") or solidarity with the child

  relative to the inner capsule, depending on the

  two distinct relative axial positions that one is a-

  to take in relation to the other.

  In these known containers there is the problem of how to obtain a tamper or first opening strip which can be directly associated with the "childproof" lid, which normally occurs with the lids or normal plugs, that is to say which are not of the "test-proof" type

  children "intended to clog containers.

  It is known that this tamper-evident band for normal covers, that is to say not of the type -2-

  "childproof" is prepared and planned to

  that it is inevitably broken at the first opening.

  The main purpose of the present invention is

  him to solve the problem creating a "child-proof" type of cover which is associated in a simple and inexpensive way a device or band

  inviolability of first opening.

  An advantage provided by the present invention is

  to be applicable to all lids "with the

  children of the type consisting of a double capsule, the inner one intended to be introduced

  detachable on the mouth of the container, the other outside

  re, intended to be maneuvered for opening and

closing the same container.

  These and other advantages are achieved by the present invention which refers to a lid

  child-resistant type, equipped with an invi-

  lability comprising an inner capsule, provided with connecting means which allow the introduction, removably, on the mouth of the container to be closed, on which an outer capsule (capsule cover) is

  arranged and engaged in such a way that

  the conditions of freedom of rotation (condition

  "child-resistant") or solidari-

  to the rotation of the outer capsule relative to the inner one as a function of different relative axial positions taken by one with respect to the other,

  characterized in that it comprises, associated with the edge p

  Rectic of the mouth of the outer capsule in

  the front of the container, a tape of first-class tamper-

  re opening; said strip being disposed coaxially with said outer capsule so as to form a kind of extension which acts as a stop coming from

  in contact with the container body, so as to prevent

  expensive, if only through the rupture of the band itself, the axial displacement of the outer capsule relative to that inner, its normal position

  child-resistant security to that of solidarity

  to maneuver the inner capsule,

  in particular to turn it, acting on the outer capsule

pool.

  Other features and advantages of the present

  the invention will become clearer from the description of

  following detailed description of a preferred but not

  implementation of the invention, illustrated in simple form.

  as a non-limitative example with reference to the

  annexed in which: - Figure 1 is a schematic longitudinal section;

  - Figure 2 shows the same section shown on the

  1, but according to another configuration.

  Referring to said figures, there is indicated in 1 a container whose mouth, provided at the end of the

  neck 2, is blocked by a lid 3 of the type "in the e-

  proof of children. "The lid 3 indeed has an inner capsule 4 provided with an internal thread

  6 by means of which it can be screwed into a

  corresponding floor 7 on the neck 2. A capsu-

  the outer 5 (or capsule cover) is arranged on the

inner capsule 4.

  In the position shown in FIG.

  In response to the "childproof" safety condition, the outer capsule 5 is free to rotate around the inner capsule 4. This situation depends on the

  the relative axial position existing between the cap-

  the outer 5 and the inner capsule 4. This position

  tion is maintained by elastic means 8 whose function is that of tending to move the two capsules in the axial direction, keeping the capsule 5 releas-

  compared to the capsule 4. If you exert

  in the direction and direction indicated by the

  arrow 13 on the outer capsule 5 so as to

  created by the elastic means 8, the same capsule is moved axially downwards so that the teeth

  9 on the upper part of the

  inner cylindrical face of the capsule 5 matches the external toothing 10 formed on the cylindrical surface

  4. In this situation, of course,

  any relative rotation between the capsule 5 and the

  capsule 4 is prevented. In the corresponding configuration

  dante shown in Figure 2, it thus appears possible

  sible, acting from the outside on capsule 5, to pro-

  unscrewing or screwing the cap 4 onto the neck 2 of the container 1. A tamper and first opening band 12 is associated with the peripheral edge

  11 of the mouth of the capsule 5 vis-à-vis the recess

  pick 1; this band is arranged coaxially with the capsu-

  on the 5th so that it constitutes a sort of prolongation

  ment. Said strip, as an extension of the capsule 5, acts as a stop coming into contact with

  container 1 so as to prevent the movement of the

  axial cementing of the capsule 5 with respect to the capsule 4, this resulting in the passage of a "childproof" safety position, that is to say a position in which the outer capsule is free to rotate relative to the inner one, to a -5- securing position determined by the coupling

  of teeth 9 and 10. In the end, the inviol-

  lability 12 is associated with the edge 11 of the outer capsule.

  5 so as not to allow the first opening of

  re that through the breaking of the same band, which can be obtained simply by exerting strong pressure in the direction and direction indicated by the arrow 13, or else removing the same band differently. The rupture of the band 12 is facilitated by the fact that the band is formed of several segments united to each other and to the edge 11 by means of links

  which can be broken by exerting a small effort.

  Obviously the rupture of the band caused by a pressure exerted in the direction indicated by the arrow 13 is possible when the body of the container i is of such shape as to enable it, when it comes into contact with the lower edge of the strip, to act as a corner,

  so as to cause the spacing and therefore the break.

  Obviously, many changes of a practical nature

  can be made to the construction details of the invention without departing from its protective framework and its basic principles, such as

  as defined in the following claims.
