Description

The invention relates to closures for

  and especially closures of the type

indicating spoliation.

  There is a wide variety of container closures designed to highlight the fact that the container has been opened or has at least been placed in a container.

  a condition of opening after being filled These fer-

  The purpose of these measures is to assure consumers that a closure has remained in a closed position once the container has been filled and that it has not been opened before

the purchase of this container.

  The general object of the invention is a spoliation indicating closure, which does not require a special container and which can therefore be used with great

  variety of containers of common shape.

  The subject of the invention is also a closure indicative of spoliation, capable of giving a written message indicating that it has been opened once or placed in

opening condition.

  The subject of the invention is also an indicator closure of spoliation consisting simply of two

  parts and designed to be easily manufactured and assembled.

  The invention thus relates to a closure indicative of

  spoliation device comprising a capsule intended to be screwed onto the threaded neck of a container and comprising

  a seal capable of sealing the closure

  It has leading surfaces and is complementary to

  which allow the capsule to be placed on the

  for the first time after it has been filled,

  in order to bring the gasket in sealing position.

  Other complementary leading and conducting surfaces are provided and come into contact with each other after the capsule has been rotated relative to the fixed seal to produce a message or to place the closure in a state highlighting the fact that the closure has been removed from or placed relative to the container in such a state that it could be moved. These complementary leading and conducting surfaces allow the capsule and

  the packing to be moved in a single block to a posi-

  complete opening and closing Other complementary driving and driven surfaces ensure the possibility of putting the closure back on the container once it has been removed, while maintaining the closure in the established state,

  highlighting the fact that the closure was opened.

  The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting examples and in which:

  FIG. 1 is a view from above, with broken

  which is only partially represented; Figure 6 is a view similar to that of Figure 5, showing the closure after it has been placed in the open position; Figure 7 is a partial cross section of a detail of the closure shown in Figure 5; Figure 8 is a partial section similar to that of Figure 7 showing a modification to the embodiment shown in Figure 7; Fig. 9 is a perspective view showing a modification of part of the closure of the prior embodiments of the invention; and FIG. 10 is an axial section, similar to

  that of Figure 2, showing another form of

  tion of the closure according to the invention.

  A spoliation indicator closure according to the invention, indicated generally at 10, is intended to be used with containers 12 having a neck 14 which has an opening 16 through which the container can receive its contents and distribute it. The outer surface of the neck 14 presents external nets 18

  intended to receive additional nets from the iron

10.

  The closure 10 comprises a cup-shaped capsule 20 having a substantially flat top 22 and an annular skirt 24 facing downwards. The skirt 24 has complementary internal threads 26 of the threads 18 of the outer surface of the neck of the container 12. also comprises a liner 30 disposed within the capsule 20 The lining 30

  has an annular rim 32 facing downwards,

  sensing an outer ring surface or ring and

  cylindrical 34 friction which is housed in the opening

  16 of the neck 14 of the container 12, in close contact with the inner wall 35 of the opening 16 A cam surface 36 is provided below the friction surface 34 to assume a guiding function during the introduction of the filling 30 in the opening 16 of the

neck 14 of the container 12.

  The gasket 30 is held relative to the capsule 20 by means of a central hollow pin 38 projecting downwards, made in one piece with the capsule 20 and passing through a hole 40 axially passing through the gasket 30. the lug 28 protruding through the opening 40 is deformed to present a head 42 similar to that of a rivet and by means of which the

  pad 30 is held in the assembled state with the cap.

  This assembly allows the liner 30 to rotate relative to the capsule 20 and, at the same time, it

  allows a slight axial movement between the two elements.

  The capsule 20 and the liner 30 may be molded in identical or different plastics, allowing

  a certain deformation of one with respect to the other.

  For example, the capsule may be made of polypropylene

  lene to improve the grip by screwing, while the lining can be made of high density polyethylene.

  The liner 30 has two symmetrical recesses

  44 arranged in a curve around the axis of this

  The opposite ends of the recesses 44 comprise

  walls 46 and 48 which form

  against which may be applied a coaching cleat 50

  Such a cleat being placed in each of the recesses 44 and being made in one piece with the capsule 20

cup-shaped.

  As shown in FIGS. 1 and 2, the catches 50 are in contact with the walls 46 so that a rotation of the capsule 20 in the direction of the needles of a

  complementary nets 18 and 26 and thus move the farm

  ture 10 in the direction of the closure.

  that an axial displacement of the closure 10 relative

  to the container so that the cam surfaces 36 penetrate

  trent in the opening 16 of the neck 14 and that the next clockwise screwed rotation causes an axial displacement of the cylindrical surface 34 of friction towards the inside of the opening 16 and in contact with the the inner surface 35 of this opening 16 This axial movement is transmitted from the capsule 20 to the lining 30 by means of bearing surfaces 51 surrounding the

  base of the lug 38 on the capsule 20 and a surface-

  ring 52 surrounding the opening 40 In addition, a sur-

  annular face 54 of force transmission is formed to

  immediate vicinity of the circumferential zone

  20 of the capsule 20, as shown in Figure 2, in order to bear against a force-transmitting flange 56. The surface 54 and the flange 56 are complementary to each other and, when the capsule 20 is screwed on the container neck 12, the seal 30 is forced axially downwardly to bring the cylindrical friction surface 34 into contact with the inner surface of the mouth opening. When the closure 10 is in the closed position, the surface 34 of the rubbing is in contact with the inside of the opening of the

  bottleneck over an axial distance ensuring contact

  before the arrival of the closure in its fully closed position In the latter position, the lower face of the flange 56 forms a seal which is applied closely against the upper lip 58 of the neck 14 The outer cylindrical face has, -en more

  of a cylindrical surface 34 of friction having a certain

  the outer diameter is slightly greater than the diameter of the opening 16 of the neck 14 and an outer surface 10 can assume the function of a seal. The packing is preferably made of a plastic material having certain qualities of elastomers which allow deformation and movement towards a

nesting position.

  In the initial sealing position of the iron

  10 on the container 12, the cleats 50 for training

  are in contact with the walls 46 of the recesses 44, in which case a window 60, formed in the top 22 of the capsule 20>, is in alignment with a message or a

  indicated in 62 In the embodiment of the invention

  As shown, marker 62 is in the form of the word "sealed." This word is the message that appears after the container 12 has been filled and closed with a closure 10, either manually ,

  automatically, for the first time.

  To open the closure 10 and remove it from the

  12, the capsule 20 is grasped in the conventional manner and is rotated counterclockwise, as seen in FIG. 1. During this rotational movement of the capsule 20 in the opposite direction to the needles. of a watch, the liner 30 remains in a fixed position relative to the neck 14 due to the adjustment

  tight and extended contact between the friction surface 34

  This has the effect of moving the tabs 50 away from the walls 46 and towards the walls 48. When the driving tabs 50 end

  by coming into contact with the walls 48 while the cap-

  sule 20 is turned counterclockwise

  of a watch, the window 60 has left its position of

  62 and has arrived in alignment with the second message or mark indicated in 64. In this case, the

  message indicates that the container has been opened.

  Before the tabs 50 come into contact with the walls 48 following the rotational movement of the capsule 20 in the counterclockwise direction, that is to say in the direction of opening, the cleats 50 must travel an arc of 30 or more, which has the

  effect of simultaneously wearing the lower extremities

  65 of the catches 50 against the cam surfaces 66 formed on ramps 68 made in one piece with

  the seal 30 at the bottom of each of the recesses

44.

  The movable capsule with respect to the remaining part of the closure causes the ends 64 of the catches to come into contact with the cam surfaces 66, which has the effect of axially deforming the capsule 20 with respect to the pad 30 to that the tabs 50 pass on the other side of the ramps 68, the cleats then abruptly falling into cavities 70 formed inside the recesses 44, between the ramps 68 and the wall surfaces 48 When the cleats 50 have reached this position, the

  window 60 is in alignment with marker 64, indicating

  as the container has been placed in a condition allowing its opening Continued rotation of the capsule 20 in the counterclockwise direction brings the tabs 50 into contact with the wall 48, so that an additional rotation causes a single block displacement of the capsule 20 and the seal 30, which has the effect of axially displacing the closure 10 and

  to disengage the cylindrical surface 34 from friction of the surface

  inner face of the neck 14, so that the closure 10 can be completely removed from the container. During the initial movement of each latch 50 from the closure-closing position 10 and until the latch approaches the cam surface 66, the capsule 20 traverses an arc of about 30, which As a result, a corresponding axial movement of this capsule During this time, the liner 30 remains fixed, without turning, with respect to the opening of the neck, so that the container remains sealed. This movement of the capsule has the effect of eliminating the the force-transmitting surface 54 and the flange 56 and away from each other so that the only force applied by the capsule 20 to

  the seal 30 is transmitted by the ends

  This force is a minimum and is significantly less than the friction generated between the cylindrical surface 34 of friction and the inner surface of the opening of the neck 14. In this way, the friction forces existing between the capsule and the liner 30 and being able to rotate the lining are minimized and

  maintained at a value lower than the friction forces

present on the surface 34.

  After the closure 10 has been removed once from the container 12, the window 60 is in alignment with

  mark 62, indicating that the closure has been opened.

  When replacing the closure 10 on the recess

  12, the capsule is turned clockwise. This brings the opposite surfaces of the cleats into contact with a stop wall or driven surface.

  formed in front of the cam surfaces 66, on the ramps 68.

  In this position, the window 60 remains in alignment with

251432 9

  mark 64, which shows that the closure 10 has been opened and allows, at the same time, to provide a means by which the drive cleat 50 transmits the counterclockwise movement to the lining. sealing so that the capsule 20 and the seal 30 move axially in a single block to bring the cylindrical surface 34 of friction into contact with the surface

  inside the opening 16 of the neck.

  Referring now to FIGS. 3 and 4,

  it can be noted that the depth of the recesses 44 deli-

  The sizing of the walls 46 and 48 is greater than the height of the ramps 68. This sizing prevents the lugs 50 from being deflected upwards a distance greater than the height of the wall surfaces 46 and 48, so that the lugs can not to cross the walls 46 and 48, both in the direction of the closure and in the direction of the opening of the closure 10 In addition, the height of the

  ramps 68 is chosen so as to constitute a dimension

  axially greater than the amplitude of any axial movement that the lug 38, passing through the opening 40, allows between the capsule 20 and the liner 30 This forces the

  capsule 20 and the seal 30 to deform one with

  port to the other and the lower end 65 of the stopper to return axially in the cavity 70 when the stopper 50 passes on the ramp 68 This also ensures entry into

  contact of the catches 50 with the stop surfaces 72 when

  that the capsule is moved in the direction of the shutter to return the closure 10 to its closed position

tight on the container 12.

  The inside diameter of the opening 16 of the neck 14 of the container 12 being known, it is possible to choose

  easily an adjustment dimension for the cylindrical surface

  This dimension ensures a tight fit and friction such that a resistance is opposed to the rotation of the liner 30 relative to the container 12 while the capsule 20 is turned from its closed position to its closed position. opening position. It should be noted that the recesses 44, the walls 46 and 48, the catches 50 and the cavities 70 are

  arranged in pairs in which these pieces are

  strongly opposed to each other

  have an even or odd number of these uniform pieces

  In the described embodiment which uses pairs of pieces, the liner 30 has two sets of marks 62 and 64 which are also opposed to each other.

  diametrically to each other This makes it possible to assemble

  20 and the liner 30 so that one of the lugs 50 can be disposed in one or other of the cavities 44.

simpler appearance.

  FIGS. 5, 6 and 7 show another embodiment of the invention which may be identical in all respects to the embodiment described with reference to FIGS. 1 to 4, except that the capsule 20 has a

  window 60a which, in the closed position of the shutter

  Figure 10a on the container 12, includes a cover member 80 This cover member 80 forms a curved portion attached to the remaining portion of the capsule 20a by weakening lines or breakable areas indicated at 82 in Figure 7 The underside of the cover member 80 includes cams 84 and 86 which are intended to engage a platen 88 formed on the top face of a trim 30a. message such as the word "sealcd" and the top of the tray 88 may also present a message such as the word "opened". The operation of the embodiment of

  figures 5 to 7 is the same as that of the form of

  previous situation by the fact that, during a movement of

  of closure 10a, the packing 30a remains in positive

  fixed relative to the neck 14 of the container 12 but that, when the cam 84 comes into contact with the plate 88, the fragile and adjacent zones 82 break> so that the covering element 80 separates from the remaining part of the capsule 20a This element leaves an open window 60a which makes the "opened" message appear on the plate 88 In this way, once the closure Qa has been placed in a condition allowing the opening, the message carried by the plate 88 remains inside the window 60a, since the driving tabs 50 are in the cavity 70, as shown in FIG. 4, so that

  that in the course of all subsequent movements of opening

  ture and shutter, the tray remains visible through

window 60 a.

  FIG. 8 represents another modification made to the embodiment of FIGS. 5 to 7 and in which a covering portion 90 is delimited on three sides by lines of weakness and breakable zones 82. However, at least one end of FIG.

  the recovery part 90 remains connected to the remaining part

  aunt of the capsule 20, at a point 92 forming a hinge.

  In this variant of the invention, a cam 94 located on the lower face of the element 90 covering

  comes into contact with the tray 96 following a rotation

  of the capsule 20b, so that the element 90 of

  recovery rises and pivots around the hinge 92.

  In this variant, the opening movement is made apparent by the fact that the recovery portion 90 is not

  more flat or flush with the

thus obvious the spoliation.

  In the embodiments of FIGS. 5 to 8, the opening movement is carried out while the packing has or remains fixed relative to the neck of the receptacle.

  that the driving element 50 comes into contact with the

  led wall 46 of the packing 30 a or 30 b.

  As shown in FIG. 9, in certain applications of the invention, it may be necessary to vary the friction achieved by the friction surface or ring 34. In FIG. 9, this is obtained by means of several ribs 100 formed on the outer surface of the flange 32 to form a surface 102

  In this case, the number, the space-

  and the degree of tightening with the inside diameter of the neck 14 can be modified to adjust precisely

When the latter is placed on a container, the threads engage and the capsule 112 causes the plate 124 to axially deform the segments 120 around their hinges or hinges 122 to bring them in contact with the inner wall of the opening 16 and thus establish the friction necessary to resist the rotation of the liner 114 during the opening movement of the closure 110

  Several embodiments of the spoliation indicator closure according to the invention have been

  described, embodiments in which spolia-

  tion, that is to say a positioning of the closure in a state allowing its opening, is made obvious either

  by means of a message, either by the appearance of the closure.

  In some embodiments of the invention, a printed message appears on the surface of the closure, indicating that the latter has been sealed so that, subsequently, when a capsule is rotated in the direction of opening, that message is replaced by another message indicating that the closure has been opened or placed in a state permitting its opening Then the closure can be put back on the container and removed from the container as desired, but the message or configuration of the closure always indicates that the capsule has been opened once The message is changed by means of a capsule and a seal movable relative to each other, the seal being held in a fixed position by relative to the container by means of a tight frictional fit of the liner while the capsule is rotatable During the relative rotation f of the capsule and liner, the message or condition t of the capsule changes and the capsule is moved axially a short distance from its frictional contact with the liner to minimize frictional forces that could tend to move the liner until the capsule goes to its final position indicating that the

  closure has been opened In all forms of

  spoliation is indicated by a device producing a friction which ensures the fixed position of the lining during a relative rotation of an outer capsule from its initial position of closure to a position of opening Once the capsule has arrived in the open position, it remains
