"Container lock with tamper-proof device"

One knows containers which are provided with a frayable guarantee element which provisionally covers the lid or the cap adheres to the container body, the integrity of this element guaranteeing the integrity of the contents. With these containers the breakage of the element irreversibly exposes the cap; this cannot with the container body more to be blocked.

The purpose of this invention is to improve this known device; a cap is used for this purpose on a container proposed that can rotate on its axis to reversibly from a position in which it is axially with the container body is blocked, to move into another position that makes it axially movable, as well as a frayed guarantee element, which temporarily holds the cap in axially blocked position and prevents it from rotating, the rupture of this element So it is necessary to be able to pivot the cap and bring it into an axially free position for the first time.

Such a device can be used in particular for the aerosol container of the French patent 69 0145O dated January 24, 1969 im Name of this applicant and its first addition 69 31454 of

309827/0461

16.9.1969 are used, for which an intermediate piece is provided between the container body and the cap , which is permanently attached to the container body, which facilitates the attachment of the permanent locking devices that are not manoeuvrable to hold the cap axially in a certain angular position .

According to one embodiment of the invention, the cap is a distributor cap and its axial movement in free position is known per se restricted in both directions, this movement then being of the desired width to allow the cap to operate the distributor valve for the contents of the container .

According to one embodiment, the guarantee device takes the form of a tear-off element and an additional recess, the element and the recess being arranged identically , one on the cap, the other on the container body or on the intermediate piece attached to it.

Advantageously, the tear-off element is a bow or an inverted U-shaped bracket with two legs which are attached to the container body or the intermediate piece so that they can be frayed out at their ends , the U-cross piece being at the level of a notch on the cap to facilitate between to be able to take two fingers.

In general, the cap can temporarily be firmly connected to the container body or the intermediate piece by pin and notch. The tenon or notch is formed on a tearable member which is frayed attached to one of the two connected elements. Appropriately, this organ is a ring that goes around the entire container cap.

The tamper-proof closure according to this invention thus belongs to a combination which contains permanent devices with the help of which two elements can be axially blocked if desired, one of which is a cap and the other is a container body or an intermediate piece connected to this feat, wherein the axial locking occurs when these two elements are in rotation on their common axis to each other in a certain angular range of their rela tive displacement.

According to a particularly advantageous embodiment, these are permanent locking devices with elastic deformation and expansion, which provides a convenient way of joining the two separately manufactured elements by they are axially pressed against one another when they occupy the above-mentioned angular range.

Appropriately, the guarantee body belongs to one of the two to be joined Elements and is adapted so that it can be received in a seat on the other element, with the interlocking of the organ and the seat, on the one hand, the position of the two elements to be joined in the above-mentioned angular range guaranteed and on the other hand locked in rotation. The joining of the two elements, their temporary Locking in rotation and its temporary axial locking are thus realized in one and the same operation; this joining is therefore carried out so that the axial loosening of the The cap requires the rupture of the guarantee organ, followed by a rotation on its axis. This last aspect offers an additional one Advantage, because it allows you to get to know the continuous operation of the lock from the very first use.

The invention also relates to particular types of construction of the above permanent axial locking devices.

The identical or analogous elements of the above embodiments are identified by the same letters or index numbers shown on all drawings.

The closure devices which are the subject of this invention are described in the position they normally assume the container upright and the cap on top.

In Figs. 1 and 3, a container R is equipped with a distributor cap C, an intermediate piece M is between the elements R and C attached. The container R has at its upper end a frustoconical wall 1 which converges upwards and ends in a protruding collar 2 which surrounds a valve opening, not shown. The intermediate piece M consists of several elements made from a single piece by molding from plastic, namely: a horizontal one flat disc 3, an inner tire with a vertical axis 4 joined with the disc 3 on the periphery thereof, and an outer tire 5, which coaxially surrounds the tire 4 and is connected to it by a horizontal wall 6 in the form of a bridge. That Intermediate piece M is attached to the container R by a known device held by the cramping of the collar 2 in the central hole of the disc 3, with elastic expansion deformation.

The inner tire 4 extends partly above and partly below the horizontal disk 3. Its upper edge is

309827 / CU61

22638U

wanders for a motif that takes up a third of the circumference and repeats itself three times on this with a 120 ° rotation. This motif shows in sequence: a horizontal bearing 7, corresponding to a non-curly part of the upper edge of the tire, a vertical straight edge 8, a horizontal one Bearing 9, which is lower in relation to the bearing 7, a rising ramp 10, a horizontal bearing 11, which is an intermediate layer occupies with respect to the bearings 7 and 9, and a vertical straight edge 12, which is attached to the bearing 7a of the following motif connects.

The outer tire 5 extends partly above and partly below the horizontal bridge 6, which is at the level of the lower Edge of the inner tire 4 is located.

The intermediate piece M is supported on the container R by connecting the frustoconical wall 1 to the lower edge of the outer tire 5. The upper edge of this tire is provided with a bend or bead 13 protruding inward, provided, wherein the bead formation can be limited to circular arc segments with gaps on the outer circumference of the tire are distributed.

An arch-shaped element 14 with a horizontal web 15 and two vertical legs 16, made of one piece with part M cast, frayed closes to the upper edges of the hoops 5 and 4 by the lower ends of these two legs at.

The cap C with distribution channels, which will not be described in detail, has a top wall 17, flat and horizontal, and a cylindrical shell 18. The top wall has a recess 19 which forms an angular sector of the shell 18 at the top of the same. At the two ends of this sector are two vertical slots 20 on the whole remaining height of the jacket incorporated, from the bottom 21 of the recess 19.

The jacket 18 is provided along its lower edge with a bead 22 which protrudes outwards. Just like that Bead 13, the bead 22 can be reduced to circular arc segments that are in gaps on the outer circumference of the jacket

309827/0461

22638U

are distributed, provided that the jacket bead segments are longer than the spaces between the segments of the bead

The jacket 18 has, protruding on its inside, 3 vertical grooves 23 attached at 120 ° from one another.

According to a known attachment, the beads 13 and 22 in the meridional section have matching profiles that allow to fit the jacket 18 of the cap C in the space between the tires 4 and 5 and there by elastic deformation with subsequent expansion, the sticking between the beads in practice a permanent locking which prevents the cap from separating from the container by lifting it.

Parts R, M and C are manufactured separately. After the container R has been filled, the intermediate piece M is fitted by latching it into place of the disk 3 with the collar 2. Then the cap C is placed in the axis of the container in which the vertical grooves 20 of the jacket 18 aligned with the legs 16 of the tear-off sheet 14 and the cap C is forced into the intermediate piece M by both being brought closer to one another by axial displacement, the engagement of the beads preventing their separation by axial displacement in the reverse direction, as set out above. As a variant, you connect parts M and C by approximating them axially and assemble the whole thing by latching into the collar 2.

The whole realized in this way is in the pictures 1 and 3 shown state. In order to achieve it, the grooves 20 had to be aligned with the legs 16 and this necessity has in turn determined the position of the ribs 23 in relation to the upper edge of the tire 4. As from picture 3 As can be seen, the ribs 2 3 are then in contact or almost in contact through their lower end with an intermediate bearing 11 of this upper edge, so that the cap C with the container R blocked axially is, both down and up. It is also blocked from rotation by the presence of the legs 16 in the grooves 20.

To operate the distributor cap, the element 14 must first be torn off to free it from rotation. You leave it then pivot on its axis, counterclockwise, until

309827/0461

the ribs 23 are perpendicular to the lower bearings 9. The cap is then free axially downwards, as far as necessary is to operate the container valve, and it can work in reciprocating motion in a known manner, the lower Limitation of their stroke is determined by contact between the ribs 23 and the bearings 9, while their upper limit is determined by The beads 13 and 22 are hooked in. After use, it is enough to turn the cap in the opposite direction to the state of Fig. 3, and to block them axially downwards, preventing any accidental operation of the distribution system prevented; this is a significant advantage especially with dangerous or expensive products.

The vertical straight edges 8 and 12, on either side of each rib 23, form stops for them, which in both directions limit the amount of rotation of the cap. If the rib stops on one or the other of these stops, you are ensure that the cap is axially blocked or released, depending on whether the stop is a movement in or against finished clockwise.

As can be seen from the drawings, the crosspiece 15 of element 14, which is located opposite the recess 19, can be easily touched with 2 fingers, which makes it easier to tear off this element; the main purpose of the recess 19 is in rest of the user's thumb uptake and relief actuation of the manifold by aligning the beam accordingly.

The cap is made to rotate by the sliding of the jacket 18 on the outer surface of the tire 4, the tire 5 represents an additional guide element. The tire 4, higher than the tire 5, also serves to support the cap when fitting to guide axially.

The whole thus arranged allows each of the three components separately and completely to make and the Monday by simply latching or. Perform fitting. The assembly requires such an adjustment that after assembly the whole thing is blocked both axially downwards and in rotation is located and that on the one hand a guarantee band must be broken and on the other hand a rotation for the first actuation

309827/0461

on its axis.

The embodiment of Fig. 2 corresponds to that of Fig. 1 and 3 with the exception of the guarantee device. In Fig. 2 the tear-off element 14 and the grooves 20 are missing. The outer tire 5 of the intermediate piece M has in the meridional section a stepped profile with a horizontal step 24, which the transition between two Zones, the lower and the upper, forms, these deepening is arranged. (The step 24 is also present in the case of Fig. 1 and is visible in Fig. 3.) The step 24 is toothed 25 provided. A tear-off ring 26, which is provided with a gripping tab 27, and with frayed connection points 28 the outer cylindrical side of the cap C closely surrounds the upper zone of the tire 5 by resting on the step 24, the teeth 25 being additionally received in a notch which is attached to the lower edge of this ring. The whole, Serration notch, blocks the cap from rotating, the contents of the container being inaccessible as long as the ring 26 is not torn off became.

The whole of Fig. 2 has the same advantages as already described. The cap C can be made entirely from one piece with the ring 26, and then simply press-fit to be connected to the piece M, the presence of the serration and the notch giving the elements C and M the necessary orientation gives to block them axially in both directions after fitting. In the embodiment of Fig. 4-8 is the part 7 differs from those in Fig. 3, essentially in the absence of recesses on the upper edge of the lower tire 4 as well as the shape of the bridge 6, which connects the two tires 4 and 5. This bridge contains full angular sectors 29, separated by circular arc windows 30, the windows and the full parts being repeated three times in a 120 ° rotation, along the annular space between the tires.

In a clockwise direction from a window 30, each full part 29 has, one after the other, a lower horizontal bearing 31, an ascending one flat vertical side 32, an upper horizontal bearing 33 and a sloping flat vertical side 34, the Pages 32 and 34 are arranged in radial planes.

The lower edge of the cap C has a broken profile

309827/0481

22638U

Line on to form protruding 3 teeth 35 that are on the circumference are distributed at intervals of 120 °. Each tooth has a lower horizontal edge 36, a vertical straight edge 37 and an inclined straight edge 38. The teeth 35 are separated from one another by upper horizontal bearings 39.

The guarantee device includes a tear-off tab 40 which is molded in one piece with and with the cap C is connected by fraying tape. The tab 40 has an inverted T-shape, firmly connected to a vertical shaft 41 with the jacket 18 of the cap, and a lower crosspiece 42 which fits into a notch 43 with a corresponding tangential dimension, in the upper edge of the tire 5. Same as the guarantee devices described above has the one, which consists of the elements 40 and 43, as a purpose of a temporary blocking in Rotation of the cap C while this one with respect to the intermediate piece M assumes a certain angular position; for this position the teeth 35 prevent any axial displacement with respect to the bearings 31 the cap down, even after tearing off the tab 40. As soon as this is removed, the cap must be turned counterclockwise pivot and bring the teeth 35 opposite the windows 30 to operate the distributor cap can. Then you can Re-lock the cap by turning it clockwise, its angular travel limits being by the vertical flat sides 32 and 34 which frame each sector occupied by a window 30 and a bearing 31 can be determined.

The embodiment of Fig. 4-8 shows, compared to the previous ones, the advantage of better guidance of the jacket, when this covers the tire 4 over a greater height.

The applications of Figs. 9-11 relate to containers with a removable cap so that it must be lifted completely to have access to the content.

In Figs. 9 and 10, which relate to an aerosol container, the disc 3 of the intermediate piece M sits in it own level to the outer tire 5, which extends upwards, from the disc, and in a suspension bead 13 ends, also extends downwards and extends to the truncated cone shaped side 1 of the container R supports. The inner tire 4 is reduced to a simple vertical lip that rests on the

309827/0481

22638U

upper side of the disc 3 is formed.

The bead 13 is limited to 3 sectors with regular spacing on the corresponding circumference. It is the same with that Bead 22 which provides the lower edge of the shell 18 of the cap, the length of each bead segment 22 being less than that of the spaces between the bead segments 13. This provides a series of angular positions around the cap C. to keep connected to the container by engaging the beads 13 and 22 and another that allows the slight lifting of the cap and also easy to bring back. Despite these attachments, however, the beads 13 and 22 are profiled so that that the parts C and M can be connected by fitting and that, so that for the first lifting of the cap, the tearing off a tamper-evident band becomes necessary, with subsequent rotation of the cap.

For this purpose, a sector 5 'with a smaller thickness is provided on the tire 5, between two bead segments 13 through Removal of material on the inner surface of the tire. On the other hand, the cap shell has nearby on its outside its lower edge is a tear-off plate 44 which is located between two bead segments 22.

As has already been said, the beads 13 and 22 make it possible to connect the elements C and M by fitting by approaching them on their common axis. The thickness of the plate 44 is such that it is opposite the thin sector 5 ¹ and allows this fitting. When so attached, it can abut against one or the other of the two bead segments 13 surrounding the sector 5 ″, thereby limiting the freedom of rotation of the cap C in both directions Removal of the cap thus requires tearing off the wafer 44 with subsequent rotation of the cap.

Fig. 11 shows the application in a tablet container with a break-proof lock similar to that of Fig. 9 and 10. In Fig. 11, the container R is a simple tube made of light metal, aluminum or similar material that normally is used to pack tablets or granules.

309827 / 0A61

In certain cases it is important to have only so large gaps between the bead segments 13 that the Bead segments 22 can pass in order to limit the open position of the cap to a very narrow angular range and e.g. to make opening the container very difficult for a child.

Of course, those described and illustrated above can be used Devices received numerous variants and changes in detail without therefore departing from the scope of the invention.
