FR2589826A1 - GLASS COVER FOR SAFETY - Google Patents

Abstract

THE INVENTION RELATES TO A SAFETY GLASS COVER. IT SHALL BE USED AS A "CHILD PROOF" TYPE SAFETY COVER (CHILD PROOF) ON CONTAINERS 1 WHICH SHOULD NOT BE OPENED WITH EASE BY CHILDREN; IN ADDITION, IT MUST ALSO BE USED AS A GLASS OR A MEASURE FOR DETERMINING THE SUBSTANCES CONTAINED IN CONTAINER 1. THIS KIND OF USE IS VERY FREQUENT IN THE CASE OF CONTAINERS 1 INTENDED TO CONTAIN LIQUIDS OF DIFFERENT NATURES AND IN PARTICULAR OF PHARMACEUTICAL SUBSTANCES OR DRUGS.

Description

Metered glasses are already known for

  accompany preparations that are mainly in the form of liquid substances. It is also known to provide dosing glasses designed so that they can be adjusted in the inverted position directly on the lid of the container in order to occupy the least possible space. This adjustment

  or introduction takes place by pressure in such a way as to

  the container lid to enter inside the

  measuring cup and to assume a coaxial position

  port to the latter. The measuring cup is thus

  ge by pressure, in contact with the outer walls

  of the lid so that it can be

  extracted by exerting an appropriate action to

paration in the axial direction.

  The main object of the present invention is to solve the problem of creating a lid which is structured so that it can be used as a

  measuring cup or dosing device and also

  safety cover of the "child proof" type (on the

  proof of children), that is to say a lid that can not

not be opened by children.

  The advantages of the present invention are the simplicity of construction and operation and the feature that it can be applied to any

  what type of lid or cap.

  These and other advantages are achieved by the present invention which relates to a safety glass lid-type of "child-resistant", characterized in that it comprises an outer cover acting

  of glass arranged so that it can receive at its

  coaxially, an inner capsule or cover

  clog to butcher; provided that said lid

  glass function is free to rotate coaxially

  relative to the inner cover; being also

  means for retaining the axially

  said lids introduced into each other

  to prevent the exit even during the eventual

  relative rotations and not allowing their release

  in the axial direction only when the outer cover

  glass function takes a predetermined position

  relative to the inner cover.

  Other features and benefits of this

  invention will become more clearly apparent from the description

  following detail of a preferred embodiment but not exclusive of the invention itself, given by way of non-limiting example with reference to the accompanying drawings, in which: - Figure 1 shows a schematic sectional view executed along a longitudinal median plane; - Figure 2 shows a schematic section executed

  along the line I-I of Figure 1.

  Referring to these figures, we have globally

please 1.

  An outer cover 4 is fitted to the cover 3, the first being arranged so that, once separated from the cover 3, it can also be used as a glass or dosing measure. The lid 4 is coaxially fitted on the lid 3 and is dimensioned so that it can receive the latter completely inside. The lid 4 is fixed axially to the lid 3 of

  in such a way that he is free to turn in relation to that

  around the common axis. Indeed, in correspondence of the inner cylindrical surface of the cover 4 making

  function of glass is provided a series of radial elements-

  protruding 6 arranged in a ring. The projecting elements 6 are separated from each other by empty spaces 8 arranged at regular intervals and are dimensioned so that they can be introduced from the front and from the measurement into empty spaces 7 which coincide exactly

  and which are between similar salient elements

  5 protruding radially outwards and

  placed in a ring on the outer cylindrical surface of the

cover 3.

  As clearly depicted in Figure 2, the

  salient elements 6 are dimensioned in such a way that they

  can be introduced face-to-face in the empty spaces cor-

  7 of the cover 3 and the projecting elements 5 are dimensioned so that they can be at their

  introduced from the front and from the measurement in the spaces

  8 because of the fact that the projecting elements 6 and the corresponding empty spaces 7 intended to receive them have different extensions on their periphery, it is obvious that the introduction of face from one into the other is possible only when the lid

  4 takes a predetermined position with respect to the covert

  key 3, this position corresponding to that represented on -4-

  Figure 2. In this position it is possible to identify the cover

key 4 of the lid 3.

  In all other relative angular positions

  we can not perform the nesting, that is to say the

  troduction of the salient elements 6 of the cover 4 in the empty spaces 7 of the cover 3. This means that if the cover 3 is housed inside the cover 4, it can not be extracted. Ultimately, the lid 4 can be rotated around the lid 3 without

  this may cause the unscrewing of the latter

  cipient. It will only be when the lid 4 has been separated from the lid 3 that it will be possible to give a course when the container is opened by acting on the same lid 3 while the lid 4 can be used as a glass or

dosage measurement.

  At the moment of closing, of course, after having

  screwed on the neck of the container the lid 3,

  the cover 4 on the latter, for example in

  so that the salient elements 6 are axial

  aligned and can penetrate inside

  these corresponding voids 7 and then printing, after a-

  see said axial introduction, a rotation which makes the projecting elements 6 no longer coincide

  with the corresponding empty spaces 7.

  It is easier to make said adjustment by

  the simple introduction by pressure in the axial direction

  4 of the cover 4 on the cover 3. In this case, as clearly visible in FIG. 2, the projecting elements 6 of the cover 4 and the projecting elements 5 of the cover 3 are provided with inclined surfaces so as to allow, through the exploitation of the deformability - 5 elastic of the same elements, only the introduction

It should also be noted that this safety system can be applied to any type of inner cover, including the covers provided with stripes. inviolability,
