Description

The invention relates to closures for containers, and more

especially closures

type indicating spoliation.

  There is a wide variety of container closures that attempt to demonstrate that

  container has been opened or at least placed in a

  allowing it to be opened once it has been filled.

  The purpose of such closures is to assure consumers that they can be confident that a closure has remained in a closed position once the container has been closed.

  filled and not opened before purchase.

  However, many of these closures can be

  forced by a delicate manipulation.

  Such a type of closure uses a seal or destructible seal that covers the opening of the container and is linked to the edge of the opening The seal is protected

  any premature deterioration by a cover or bou-

  chon screwed or elastically snapped onto the container.

  Access to the contents of the container requires removing the lid and puncturing the lid. Therefore, removing the cap visually highlights whether

  the container has remained sealed or not since filled

  However, with such containers and such closures, the seal may be perforated and the customer may not be notified of the state of his purchase before removing the cover. In addition, the seal may be completely removed and , unless the consumer

  is accustomed to packing or has another recipe

  to which the open container can be compared, it may not be apparent that the package has been opened previously.

  According to the invention, a closure

  carrying a spoliation witness may be attached to a

  in any conventional manner, for example by screwing or elastic locking, and this closure can be of any one of several types that are childproof. The closure is made at least partially of transparent material and includes a cover or stamp 2 _ consisting of a thin sheet of plastic treated or treated paper such as crystal paper The underside of the stamp comprises a pressure-sensitive adhesive or, in the case of a thin sheet, it can be treated with Therefore, after a container has been filled with a product, the manufacturer applies the closure to the container to bring the underside of the seal into contact with the container.

  a bond and in the case of thin sheets of plastic, the filled container and the lid

  can be passed in an induction field to provoke

  In each case, the contents of the container are sealed and the transparent closure rehd the seal or seal completely and clearly visible, so that its integrity can be determined, especially by comparison with similar containers in the same display. In a second embodiment of the invention, the upper part of the seal is linked by

  a part on the underside of the lid The movement

  opening force requires either a rotational movement or an axial movement of the closure relative to the container and this movement breaks the seal, so that it appears visually obvious that we have tried

  open the container by removing the lid

  This is particularly obvious when

  product racking can be found on shelves at a retail outlet, where a comparison can be made

  with identical packaging on the

  However, even a single package clearly shows, by the breaking of the stamp, that it has been the object of an earlier attempt to open. This break in the stamp is underlined by the use of marks or of

  contrasting colors on the opposite sides of the stamp.

  In other embodiments of the invention,

  vention, the seal is attached to the underside of the lid by means integral with the latter and, in another embodiment of the invention, there is provided on the underside of the lid, means for rotating the cover against the seal or seal on a container, in the direction of closure, but these means act to come into contact with the seal and tear it if one tries to remove the cover in the direction of the opening In a In another embodiment, the means for rendering the obturating element visible also constitutes a secondary seal or seal intended to seal the container after the thin main sheet or the crystal paper seal has been sealed.

  or seals used with the closure according to the invention.

  Part of a package 10 having a closure 12 according to the invention, shown in the closed position on a container 14, is illustrated on the

  FIG. 1 The container 14 comprises a neck 16 which

  conventional threads 18 screwing formed on its outer surface and complementary formed nets 20

on the closure 12.

  The closure 12 comprises a top 22 in the form of a flat disc, from which a cylindrical skirt 24 descends which

  the inner wall has the threads 20

  10, a sealed seal or seal 30 is disposed between the closure 12 and the container 14. The seal 30 is made of a thin membrane of treated paper such as crystal paper or a thin sheet of paper. of plastic-coated metal, for example a thin aluminum foil The seal or cap 30 is disposed inside the closure 12 and its peripheral portion 32 comprises a pressure sensitive adhesive so that when the closure 12 is placed on the container 14, the lid 30 binds to the closure lip of the container 14 to seal the contents inside the container 14 In the case'of a lid 30 consisting of a thin sheet of metal, the underside of the seal or seal may be treated with a plastic coating so that the package 10, after the closure 12 has been placed on the container 14 for the first time, can be passed ns an electric induction field causing the connection by heating the thin

leaf on the edge of the neck 16.

  The lid is made of a transparent material

  parent and, in the closed position of the package

  , the lid 30 applied to the container 14 is clearly

  visible through the closure 12 For this purpose, the

  cover is preferably made of a plastic material

  Such as polypropylene, which has the property of presenting a sharpness of contact. By sharpness of contact is meant the property according to which objects such as

  that the lid 30, brought into contact with this material, appears

  clearly visible, while

  slightly spaced from the material are less distinct.

  or seal being in contact with the underside of

  the closure 12, the state of this operculum 30 appears easily

  In addition, the position of the cap relative to the lid is less apparent in the case where the lid is slightly spaced from the closure 12, as it is

  produced if a screw-type cover has been loosened.

  Other plastics such as polyethylene can also be used to form the closure 12, but they may give a less distinct appearance or

a whitish appearance to objects.

  After the container 14 has been filled with the product to be packaged and the transparent closure 12, as well as the seal or seal 30, has been brought into closing contact with the container 14, the seal 30 is bound to the edge of the neck 16, using the sensitive adhesive

  pressure, or by induction heating of the coating

  plastic material of the metal seal 30

  these conditions, the contents of the container 14 are sealed

  meticulously and the operculum is visible through the

  When such packages 10 are presented side by side in retail outlets,

  the consumer can easily see the state of the operculum through

  towards the transparent closure 12 If the operculum 30 has been

  broken or absent, this indicates a possibility of spo-

  the packaging, so that the packaging can be removed from

  display rack not to be distributed to a consumer.

  A second embodiment of the invention

  tion may comprise a closure 42 identical in all respects to the closure 12, except that an upper portion of the seal 30 is bonded by indicated means

  at 44 on the underside of the flat top 22 This link

  its is a permanent bond constituted by an adhesive in the case where the lid 30 is made of crystal paper, or by fusion, during an induction heating operation, in the case of a thin sheet of coated metal

of plastic material.

  If desired, the transparent closure 42 may include portions such as those indicated at 46 which are dotted to be opaque or only partially transparent. This provides zones of contrast masking an adhesive or screw threads. these areas can be used to give the packaging a decorative appearance However, the larger

  part of the top 44 is preferably transparent.

  The lid 30 can be held in position

  inside the closure 42 during the installation of the

  14 and part of the top of the operculum is linked to the iron

  Closure 42 The package 10 then has the appearing appearance

  5 o the contents of the container is masked by the seal 30 which is cons conspicuously visible through the closure 42 The nature of the connection is such that the attachment points of the container 14 to the closure 12 are permanent In Consequently, any relative movement

  closure 12 and the container 14 causes deformation

  After opening the package by removing the closure 42, the broken lid 30 becomes visible through the top of the closure 42 and this rupture easily appears. , in particular by comparison with identical containers whose lid 30 is

  intact, as can be seen in Figure 5.

  When the lid 30 has been broken, it may have the appearance as shown in Figure 6 o part of the lid 30 is torn off and removed to make partially visible the contents 47 of the container 14 Fragments such as those indicated in 48 can stay

  attached to the closure 42 and parts as indicated

  50 may remain attached to the container 14.

  Various references or various indications, such as impres-

  contrasting colors or contrasting

  in which case contrasting markers such as

  sions or colors, applied on the upper faces.

  and bottom of the operculum 30, make more apparent the

rupture of the latter.

  After the closure 42 has been completely removed from the container 14, portions of the lid 30 remain attached to the container 14 as shown in FIG. 7. These fragments as well as those attached to the closure 42 can then be removed with the fingers. closure 42 is refitted on the container 14, the unsealed sealed contents of this container is

  -5 visible through the transparent parts of the farm

  ture 42 and the absence of the lid 30 appears easily,

  in particular by comparison with identical packaging

  ticks 10 which remained totally sealed.

  Although different forms of

  of the invention are described as a screw-type closure 12 or 42, each embodiment of the

  closure according to the invention may be of the type with a socket

  elastic member which, as shown in FIG. 9, comprises a locking rib 62 formed on the neck of the

  container 14 and a complementary locking rib 60

  formed on the underside of the closure.

  which in the case of closure 42 causes

  the rupture of the lid 30 The closures 12 and 42 can

  may also be of various types that are child-resistant, these types of closures exhibiting

  locking and requiring orientation or compro-

  predetermined voltage before the opening can occur.

  In all these packages, the closures are made so as to be totally or partially transparent to make visible the sealing membrane 30 and

  a relative movement between the container and the

  ture to break this membrane or operculum.

  After the main lid 30 has been removed from the container 14, the closure 12 can be rested on the container 14, in which case the bead 69 cooperates with the inner surface of the skirt 24, as shown in FIG.

  FIG. 1, to form a seal that protects the con-

held remaining of the container 14.

  FIGS. 10 and 11 show another embodiment of the invention in which a closure 70 has a disc-shaped top 72 from which a cylindrical skirt 74 descends, the inner wall of which has the threads 20 The disc-shaped top 72 is consisting of an annular flange 76 which is formed in one piece with the skirt 74 and which may be formed of an opaque material The annular flange 76 defines an orifice or opening 78 which is closed by a packing

  80 in the form of a disc, lodged against the inner face

  flange 76, inside the closure 70.

  The liner 80 is fixed in position by any means, including

  an adhesive or an elastic interlocking

  tight fit within the skirt 74.

  The lining 80 is transparent and is made of a relatively elastic and soft plastic, for

  example of low density polyethylene supplemented with

  This makes the liner 80 relatively soft and flexible to provide sealing characteristics and at the same time allow it to be transparent. In the closed position of a package, a destructible seal 82, similar to the seal 30, is disposed between the closure 70 and the container 14. As in the embodiments of the invention described above, the seal or seal 82 may be adhesively bonded or induction heated to the lip

  sealing of the container 14 in order to hermetically seal

  the contents inside the container 14 After the package has been filled and sealed for the first time,

  the cover 82 is clearly visible through the padding

  transparency 80 so that its state is apparent Si

  the operculum 82 has been broken or if it is missing, any spolia-

  any previous opening becomes apparent and the packaging may be removed from the display so as not to

to be distributed to consumers.

  In normal use, the presence or absence

  the operculum can be seen through the transparent

  80 and, when the closure 70 is removed, the seal can be broken and removed in full so that the contents of the container 14 can be used When only a portion of the contents of the container is used, the closure can be put back into place on the container 14, which brings the lower face of the liner 80 in sealing contact with the lip of the neck of the container 14 In this way,

  the lining 80 is not only a permissible element

  both to observe the seal or main seal 82, but after this seal has been removed, the seal 80 then acts as a sealing seal for the seal.

remaining contents of the container 14.

  The destructible cover 82 can be applied to the container 14 separately from the lower face of the closure 80, or it can be mounted temporarily.

  against the inside of the closure, by an adjustment

  tightness allowed by the circumferential lip 84 of

  the cover 82, so that the closure 70 and the opera-

  82 can be placed simultaneously on the container.

  Figures 12 and 13 represent another

  embodiment of the invention, namely a firm

  90 is made of a transparent plastic material and comprises a disk-shaped top 92 and a cylindrical skirt 94. The closure 90 is designed to be

  used with an operculum or similar shutter element 96

  to the shutter element 82, which is fixed in contact with

  hermetic against the lip of the opening of the container 14.

  The lower surface of the top 92 in the form of a disc

  carries a plurality of annularly spaced teeth 98,

  having a tapered leading edge 99 and an inclined rear surface 100, when considering the direction in which the closure 90 is rotated to bring it into the closed position. This configuration of the teeth 98 is such that

  that a cap 96 being housed inside the farmhouse

  90, the assembly can be applied to a container 14.

  When the closure 90 is turned in the direction of obtura-

  ration, the cap 96 can rotate with it until

  that it comes into contact with the sealing lip of the reci-

  During this shutter movement, if the shutter

  Figure 14 prevents the lid from rotating, the rear edges of the teeth 98 allow any relative movement between the lid 96 and the closure 90 However, once the container 14 is closed-and the lid 96 is bound to the lip of closing the container 14, any effort tending to turn the closure in the direction of opening causes the tearing of the cap 96 by the tapered edges 99 of the teeth 98 The torn state of the lid 96 becomes visible at through the transparent closure 90,

  which gives an indication of a spoliation of the packaging.

  In the same way, before any attempt of opening movement,

  the transparent closure 90 shows that the packaging

  lage and its operculum 96 are intact and have not been opened.

  FIGS. 14 and 15 show another embodiment of the invention in which a closure 110 comprises a substantially disk-shaped top 112 and a downward cylindrical skirt 114.

  closure 110 is made of a transparent plastic material

  parent and the underside of the disk-shaped upper surface 112 is made in one piece with the tips 116 which penetrate into openings 118 of a cover 120

  similar to the 30, 82 and 96 caps used in

  my embodiments of the invention described above.

  Once the seal 120 has been placed inside the closure 110 so that the tips 116 pass through the holes 118, the tips 116 are hot deformed to form rivet heads 122 These serve not only to hold the seal 120 in position by

  closed at 110, but also to close

  mesically holes 118 to prevent the container 14 from leaking through these holes 118 After the closure 110 has been placed on a container 14 and the operculum 120 has been

  connected to the lip of the opening of the container 14, any movement

  subsequent closure 110 causes a deterioration

  tion and tearing of the operculum 120 The state of the opera-

  This can be observed continuously through the transparent closure 110, a broken state of the operculum 120 indicating spoliation. The tips 116 such as those shown in FIG. 14 can be formed on the disk-shaped transparent packing 80, shown in FIG. on the face

  , to maintain the seal 82 relative to this garnish

  80 in the same manner as the cover 120 is attached to the closure 110 shown in FIG.

  device, any effort of opening causes a tearing

  operculum 82, making the spoliation obvious.

  Variants of the covers 30, 82 and 120 used with the various closures shown in FIGS. 1, 10 and 14 may be in the form of

  sealing or sealing elements, indi-

  130 in FIG. 16 or 131 in FIG.

  Referring first to Figure 16, the

  The sealing element 130 consists of a top layer

  The upper disk 132 may be made of paper having markers such as the lines 52 shown in FIGS. 6 and 7, or a repeated message consisting of The upper surface of the disk 132 is covered with a layer 137 of pressure-sensitive adhesive or a plastic coating which can be welded by induction heating, as shown at 136 in FIGS. 11, 13 and 15. so that, once the container has been filled and closed for the first time, a narrow band 137 formed of adhesive or coating material is activated to secure

  the closing shutter element 12 The inferior disk

  134 is made of a thin sheet or crystal paper such as that used in the lids 10, 70 and 110. When it consists of a thin sheet, a

  layer 138 of adhesive or coating material is

  to the disc 134 so that, after filling and closing a container, this layer forms a tape 138a of pressure sensitive adhesive, which adheres, in leaktight contact, to the upper lip 139 at the edge of the container. the opening of the container In the case of crystal glass, an adhesive is usually applied on the

lip 139 of the closure.

  The upper and lower disks 132 and 134 are permanently affixed to one another by bonded connections as indicated at 140 and made at one or more points between the disks 132 and 134. The control disk 132 made of paper preferably consists of an opaque material

  which is more fragile than the lower disk 134 of seal-

  Accordingly, when the transparent closure 12 is rotated in the opening direction relative to an associated container on which the sealing disc 134

  is attached by an adhesive or a coating material

  the upper disk 132 and the lower shutter disk 134 move relative to each other, but

  the bonded bond 140 resists this relative movement, pro-

  This tearing occurs through the transparent closure 12, indicating that an attempt has been made to open the container with which the closure is used. When the closure 12 is removed, the lower disk 134 shutter remains in hermetic sealing contact with the container and can be easily broken and removed for

  we tried to open the container.

  The inner surface presented by the skirt 24 above the wires 20 has an annular bead 152 which bears against the soft cardboard disc 148 during the upward movement of the closure 12 relative to the container 14, thereby separating the the disc 148 of the lower sealing disc 146 which remains fixed

  to the container by an adhesive 147 a The disc 146 of

  The layered sealing devices shown in FIGS. 16, 17 and 18 obscure the glue which has an irregular outline and which could be considered unsightly if it were not masked by opaque parts of the closure, such as

  than the parts indicated at 46 in Figure 3.

  The two closure devices 130 and 131 may be used with the tamper evidence closure 70 shown in FIGS. 10 and 11, using either the upper adhesive bead 136a, which is part of the adhesive coating. or of the mechanical connection 156 made by rivets as shown in FIGS. 16 to 18, for fixing the sealing devices to the

trim 80.

  Thus, a tamper-evident closure which is partially or totally transparent and which has a sealing cap or sealing member which can be broken and is bonded to a container so that this seal and its condition are easily visible through the closure In some embodiments, means are provided for cooperating between the lid and the closure so that any movement of the latter with respect to the lid, once it has been fixed on the container, becomes apparent through the closure

  There are also plans for

  with lids or secondary seals which come into action when the main liner has been removed, so that the closure can be resealed

  to protect the rest of the contents of the container.

  It goes without saying that many modifications can be made to the packaging described and shown

  without departing from the scope of the invention.
