"Assembled lid for containers"

The invention "relates to a composite lid for Container consisting of one for receiving on the container opening end serving ring and a detachable tightly closing cap held on the ring.

The area of application for assembled lids of the aforementioned type extends to glasses, bottles, cans and the like, namely predominantly to containers of the so-called "press-off type". In the case of containers of this type, the. As a result of this drifting up, the assembled lid comes into engagement with the container in a locking position. Danacn a rrfnen of the container or a decrease of the lid only partially without destruction is possible, namely by a portion ih the closure cap from the container and a remaining part of the container, the ring is twisted off.

109843/102 *

Composite lids of the aforementioned embodiment have proven advantageous and successful in the container industry because they have a number of significant advantages. Purely for the field of application of baby food, for example, which is generally sold in small disposable containers, the cost of the lid and the closing costs must be very low so that the entire product can be brought to the market for a reasonable cost. For such an application, however, it is also important that a tight seal on the one hand, the easiest possible removal of the cover on the other hand, and also easy manufacture and use of the cover is ensured. It has been found that push-on and twist-off lids are particularly advantageous with regard to these points of view, because in order to seal the jars tightly with such lids it is not necessary for the jars to be transferred into particularly specific positions relative to the lid, and it is not necessary to provide special facilities to the deodorant or sealing caps with predetermined! Torque screwed onto the jars and vessels, and it is still possible to control the amount of force or torque required for opening or decrease the caps ,, carefully and bounders simple and economical. It is therefore known that a push-on twist-off cover

Possess number of advantages.

Another type of known lid, which is to be regarded as advantageous from the standpoint of the convenience and economy of the manufacturer, is, as mentioned in the introduction, constructed in several parts or assembled and it has a part which is separate from the container and which is in engagement with the closure cap via suitable holding devices , however, after the container has been closed and sealed, it remains on this I, although it is not an integral part of the container. So were execution. ¹ ?, proposed for men such composite lids, in which the closure parts normally provided on the container itself at the head end or opening edge of the container as well as the. Oral holding devices are components or form elements of a separate ring which is not formed in one piece with the glass or other containers. In some embodiments of such known composite Dectels, the seal or the sealing element used in place of a seal contacts parts of the ring and not parts of the container.

In the known or proposed versions of the composite The cap itself was placed in the lid generally made in the relatively usual Y / eise, for example made of metal and had the usual cap mirror and

109843/1077

the cap edge formed on the outer edge, the respective seal of one type or the other used on the Inner surface of the cap was placed. In such embodiments known composite lid with more or less conventionally formed caps, the ring was a separately manufactured and molded part which on the other hand, however, as far as the holding and sealing devices themselves were concerned, the holding and cooperating with the closure cap cooperated, were again designed in a conventional manner or were designed in the same way like the corresponding parts, which are normally provided in one piece on the container.

The present invention seeks to provide a composite lid which has certain properties thereof various known and proposed covers can be achieved, which, however, differs from these in turn by certain differences in the design as well as others Differentiates between advantages that could not be achieved with known designs.

In pursuit of this aim, the present invention intends to to create an assembled lid, consisting of a cap and a ring, which can be assembled in an assembled, completed state placed on a container

10984371077

can be, in which, however, the closure cap can only be removed from the container by rotation, the Ring remains on the container.

Another object of the present invention is to provide a composite lid in which the closure cap and the ring is manufactured and shaped in a multi-step process, but with a portion of the assembled Lid by injection molding in one manufacturing step is molded, while the other part subsequently using at least a part of the previously formed ring or the previously formed cap is created as a manufacturing form.

The invention further also intended to provide a composite lid which consists of ring and closure cap and mark are molded as a unit, but in which the two 'components that make up the composite cap for removing the cap from the container, on with the assembled lid attached can be separated from the ring very easily, the ring remaining on the container.

The invention also seeks to provide a composite cover consisting of a ring and a closure cap which can be formed separately from one another and in which

1098 & 1 / in? 7

the closure cap in the state of use on the ring by devices is held locked, which create an increased radial play between the ring and the closure cap, so that reduced friction is achieved when the closure cap is removed.

The invention also contemplates a method of manufacture of the composite lid, in which by twofold Injection molding a ring and the cap are sharpened, which then as a unit onto the opening end of a container can be pushed open without any intended rotation, whereby this' unit can then be dismantled into two separate elements is when the cap is separated from the ring to open the container.

The invention also intends to provide a composite, A lid consisting of a ring and a cap, which ensures a guarantee closure and both an undesirable one Rotation of the closure cap indicates or allows to recognize that the closure cap has previously been removed or that such removal attempt has been made became.

In the context of the present invention, the intention is also to create a method for producing a composite, consisting of ring and cap, the

i η η nt * ι η η '■> ί

can be placed by pressing onto a container or onto a glass and in which the closure cap is rotated from the ring can be separated and removed to open.

The invention intends to use a composite cover consisting of a ring and a closure cap for container that can be easily manufactured using so-called double injection molding.

The above aims and objectives of the invention as well as similar advantages are achieved with a composite, of ring and closure cap existing lid, wherein welehern the ring and the closure cap in an assembled, sealed closing state without intention of rotation as a unit to a container aufdrückbar are and in which the closure cap / ier unit can subsequently be separated by twisting it relative to the ring, while the ring remains firmly attached to the container / s. The objects of the present invention are also achieved by a method of making the composite ring and cap. ™

The precise manner in which the objects and advantages of the invention are realized will be apparent and detailed from the following description of the exemplary embodiments shown in the drawings.

This end edge 40, which is not inclined, but runs flat, serves to touch and hold a complementarily designed, opposite one in the axial direction

pointing end face edge of the ring, while the Jchwinki'lü- | chen nit complementary inclined surfaces 42 of the ring cooperate. In the embodiment shown, a hat or recess 46 is formed in a part of the cap rim 36 _O , which has a depending part in the form of a locking tongue 48 which, in the embodiment shown, is equipped with a pair of side walls 50, which together define a locking groove 74 (Pig. 7) which is located in a lower outer surface area 52 of the ring 26.

A substantially rounded upper end portion 62 of the ring 26 lies above the hat 58 and is integrally molded with the body of the ring 26.

In the following, the reference position of the
Ring 26 to the container 22 with reference to Figs. 2,5 and 6 received. It can be seen that a bottom or lower surface 64 · of the ring 26 is arranged in direct contact with the upper side of the rib 28. A substantially annular ridge 66 extends across the top of the container 22. The ring 26 covers this groove, part of the container rib 28 and part of an upper rib 68 of the container.

This groove 66 has a number of depressions or serrations 70 (I ¹ Xg. 2), the purpose of which will be described in detail aiy later.

In FIG. 5 it can be seen that a bead or band 72
made of an adhesive material, if so desired, can be inserted between the ribs 68 and 28 in the groove 66. Such an adhesive groove can, depending on whether it is desired, be provided or omitted if pressure or vacuum seals have to be created, and
if it appears necessary and otherwise impossible to create a seal between the inner surface of the ring 26 and the outer surface of the container.

Reference is made to FIGS. 5 and 6 below.
Due to the shape of the meshing support surfaces

38 and 40 and the complementary shape of the surfaces 42 and 44 of the ring, which differs from conventional forms of closure caps, which are generally equipped with threads, there is a need to take measures to hold the closure cap in place on the ring. For this purpose, a certain amount of plastic or elastic deformation is produced in the cap rim 36 or in the tongue or groove 56, 58 of the cap rim 36 and the ring 26, so that it is possible to detach the closure cap from the associated ring 26 in the axial direction. The tongue and the groove 56,58 are made of deformable material and are dimensioned and designed in such a way that they are sufficiently flexible with regard to the force which arises when the closure cap 24 is rotated relative to the ring 26. As a result, the tongue 26 rises out of the groove 58 when rotation has taken place and then releases the closure cap for axial removal from the ling 26. As a result, is the shape of the tongue and suffered at least 56.58 au part to define the waterproofing ■ fcumgetigeneehaft the cap as well as to define xun $ en »BieJimoDWntes, welohes is necessary to ensure the encryption • ohlyJk * fpe 24 from the ring 26 to be able to remove. The relation, the check FCEI remote cap 24 as is shown in i'ig. f, and it can be seen that the closure cap 24 has its natural shape due to its inherent elasticity

^ 109843/1027

and regains compliance even after losing weight.

from Fig. 7 it can be seen that the locking part 48 via a breakable or tearable connection, for example a thin web, to the slot 46 in the walls 50 of the • ring 26 is held. It can therefore be seen that the locking tongue 48, which lies in the slot 74, offers resistance when the closure cap 24 is rotated, but then ^ if the twist is carried out anyway, either breaks or tears or is noticeably bent and then one possibly buyer or consumer indicates that the cap, which with this design of a so-called guarantee lock is equipped, has already been opened or removed.

The tongue 48 is connected via the thin web and can therefore be torn off without excessive force being exerted or removed.

w In the enlarged representation in Pig. 7 it can also be seen that a number of gripping surfaces, for example grooved, toothed or corrugated gripping surfaces 76, are provided on the outside of the cap rim 32 of the closure cap 24. This measure increases the convenience, because the material from which the assembled lid is made is naturally slippery or has an outer surface and contour that appears smooth in some other way.

The application, use and manufacture of the assembled lid will now be discussed in order to explain how a container 22 can be closed with this lid. The normal procedure here is that the ring 26 is first formed in a first work step, while the closure cap 24 is formed in the second work step of a so-called double injection molding process. However, at least a portion of the previously formed ring is used as part of the mold wall for shaping the closure cap, so that a λ zusammenge- modifying body formed in this way.

It is now assumed that there is a glass container of the shape shown in FIGS. 2, 5 and 6 and this has upper and lower ribs 68 and 28, which define an annular groove 66 between them. The entire unit of the assembled lid 20, which consists of the closure cap 26 and the ring 26 connected to it by molding, is then pressed axially from top to bottom over the upper rib 68 / without being rotated. This process is facilitated by an inclined annular inner edge 78 26 on the ring as soon as the ring 26, the position shown in FIGS. 5 and 6 assumes, but is locked in the axial direction in the assumed position because the enlarged width of the rib His further axial movement ver down -

109843/1 η? 7th

and because a shoulder 68, which serves as a partial boundary of a groove 82 which receives the rib 68, also prevents further downward movement. The bead or band 72 of adhesive material can be used to lock the ring 26 in place. When using such an adhesive tape, it also serves as a seal between the container and the ring 26 when it extends continuously over the circumference of the groove 66. When using such an adhesive, the effect of the toothing 70 is supported, which prevents the ring from twisting with respect to the container.

The Pig. 2 clearly shows that the toothing 70, which is in the

Groove 66 can be provided, can also serve to prevent rotation of the ring and that this toothing also to interact with or instead of the adhesive such an adhesive can be used. In addition, the toothing 70 can have counter-toothing (not shown) on the inner surface of the ring 26 cooperate in a known manner to engage between to create the gears. However, the engagement can also be carried out exclusively by digging the teeth 70 into the Surface 84. As soon as the ring 26 is in the position shown, it can no longer be relative to the container 22 be twisted unless it becomes a very great force

109843/1027

or a very large torque is expended. Because the cap 24 is not united with the ring 26, although both are placed as a unit on the container and although the Closure cap was formed by using part of the ring as a Pormwandung, the application leads in the direction of rotation acting force on the closure cap to the fact that this is moved upwards in the axial direction and thereby the deformation the. Tongue 66 causes in the manner already described. This tongue then comes out of the surface 60 of the ring 26 and free there will also be contact with the inner surface 54 of the closure cap 24 interrupted so that the closure cap can be removed from the container 22. The container 22 can through Reversal of the processes, namely in that the closure cap 24 is pressed again in the axial direction over the ring 26 and rotated is closed again until the surfaces 38 and 40 are flush with the surfaces 42 and 44 and take cover layers will.

The manufacture of the assembled cover 20 will now be discussed. It is initially assumed that the Hing £ 6 is to be manufactured as the first part. The production of this ring is done by injection molding, for example a ring 26 with all shapes including its top side and the shark tee for attention ? Iuf - '. ■ .- ■ η: U * .i .!. · U >.

the shape in which the now formed ring 26 is located, rotated, in the usual way with double injection molds, so that a second cavity is created, which has the outer contour of the closure cap 24 to be formed, but the inner surface or shape contour, which is now not just by a flat inner surface 86 of the cap mirror 32, but also from the inner contour of the respective grooved, with inclined surfaces and / or threads on the outer surface provided ring 26 is formed so that the closure cap is complementary in its contours to the receiving parts of the ring is shaped.

At the same time, the locking tongue 48 or a similar element is molded in one piece with the closure cap 24 so that it fits snugly and can be pulled out into the groove 74. Depending on the nature of the lock design as a guarantee lock or not, lock tongue 48 and groove 74 can be formed by different means. In other words, this means that a thin zone of weakness or a thin cross-section in the form of a tear line can be provided in the connection between the closure cap 24 and the tongue 48 and the tongue 48 can be held firmly in the groove 74 at the same time. But Bie tongue 48 may also be formed ao that it is free from slot 24 out dsm-U ¹ LFCT, however, that such a movement sufficient to increase the

Ί k Ί / 1 Il ? _ 1

- 19 -

First tear off. But such a movement can also be a cause permanent bending of the tongue. This gives the guarantee lock, because a broken or permanent one bent tongue is easy to detect.

The closure cap can be formed from a material which does not adhere to the material of the ring 26 in an adhesive manner. But it can also be used a material which is as similar or even the same as that of the ring and nevertheless f is not previously formed on Hing odär adheres connects with this. These conditions can be met by appropriately influencing the molding conditions or the like. However, similar materials can also be used for the ring and the closure cap, which would bond with each other under normal use , but can be prevented by using a suitable separating agent that the contacting surfaces of the ring 26 and the closure cap unite .

The method for shaping said parts of the assembled lid, ie the method of double injection molding, is known per se and therefore does not need to be described , because it does not form part of the present invention. This procedure is only particularly valuable

1098A3M077

fully and advantageously for the purposes of the present invention. It is believed that it is "not yet known employing such a process to form a ring and cap composite lid. In particular when there are parts that are complementary to one another and the assembled cover is produced by cooperation techniques in a double injection process. The two parts of the ring work here with each other, and not just for the sake of the compound Lid, which consists of the cap and the ring to hold together, but they also provide one Unit that provides advantages for shipping and handling. In addition, this results in sealing properties and the ability to determine the torque characteristics, which are decisive for the effort with which the cap 24 can be separated from the ring 26 as soon as the unit formed has been placed on a container.

In the following reference 8-14 is now made to Mg taken, in which a further embodiment of the present invention formed composite lid can be seen that the embodiment according to Fig. 1 - is similar to 7, but in a certain number of features that in the.. will be explained below, differs from this version.

109843/1077

Reference is now made particularly to FIGS. It can be seen that a container 22a is equipped with an assembled lid 20a. Servant susanmengesefczte lid 20 a consists of a cap 24 a and a ring 26 a. The Hing 26 a is held in a circumferential groove 66 a at the upper or opening end 30 a of the container 22 a, namely between an upper rib 68 a and a lower rib 28 a with a larger diameter. The two ribs 68 a and 28 a extend circumferentially around the opening end 30 a | of the container 22 a. Ea toothings 70 a or the like. Shown in order to prevent rotation of the ring 26 a with respect to the container 22 a, while the ribs 68 a and 28 a prevent axial attachment of the ring 26 a in both axial directions. In addition to the locking tongue 48 a, which can be received in a slot 74 a, which is defined by side walls 50 a, knurled or toothed outer gripping surfaces 76 a are provided, which correspond to the parts and features described above for the first embodiment . The closure cap 24 a also has the aforementioned stacking ring 34 a, which stands upright on the bust size of a cap mirror 32 a. A beveled surface 78 a runs along the lower surface 64 a of the ring 26 a in the circumferential direction and makes it easier to put the entire unit of the assembled ring on the container 22 a. To the ring 26 a in its position against rotation i \ st-

109843/1027

can hold a layer or a bead 72 a made of an adhesive into the groove 66 a, between the inner surface 84 a of the ring 26 a and this hat are introduced. A shoulder 80 a is used to partially define an upper Uut 82 a, • which is used to receive and lock the upper rib 68 a.

The retaining means with which the ring 26 closure cap a to the encryption ^ 24 a_ engages, are provided in this embodiment in the form of radially outwardly projecting G-ewindegänge 100, .eiche an end portion 102 having, which has a reduced radial _t expansion , while an opposite other end portion 104, ie the outer surface 106, of the threads gradually decreases in the counterclockwise direction with increasing direction of rotation when viewed from above. The edges 104 of the Gevdndegänge 100 go into the lower region of the ring 26 a.

™ These threads 100 are shaped in the V / eise that after a rotation of the closure cap 24 a with respect to the Hing 26 a of the cap edge 36 a of the closure cap 24 a, when it is in the closed position, closely pairing in the threads 100 engages, however, a gradually away from the threads 100, so that a clearance or distance is formed at a rotation of the closure cap 24, which

109843/1027

lies between the threads 100 and the cap rim 36 a. The consequence of this margin that is created is that the frictional contact between the parts is gradually reduced. This means that the radial clearance that is created serves to facilitate the axial removal of the closure cap. When the container 22 a v.ieder is closed, the reverse form of the actions must be carried out, ie the cap 24 a is brought into the correct position above g of the ring 25 a and progressively stronger and stronger by twisting clockwise sense on the ring unscrewed.

Here i'ig. 12 and 13 show the removal of the cap 24 a from the ring 26 a is carried out in the same way as in the case of the closure cap and the ring 24 and 26 according to FIG. Figo 5 and 6.

The locking tongue 48 a is the same as that already described first embodiment, and the form j of the assembled lid according to Fig. 8-14 is the same as that of the lid according to Fig. 1-7.

The method of manufacture is the same, each one too other shape used, for both embodiments same. It should be mentioned that both the ring 26 a

109843/1077

or all of the cap 24 a can be formed first and then only the other part afterwards must be shaped. In other words, that means / that it

nor is it essential that the assembled lids be made by a double injection molding process referred to above. For the Pail that the rings 26 and 26 a and the caps 24 and 24 a are to be formed separately from each other, it is only advantageous if the inner surface 54 a of the closure. cap 24 a is formed with a slight inclination or deviation from the outer surface 60 a of the ring 26 a, and if these parts are excluded for minimal interference in the vicinity of the bottom parts of the Eappenrandes 56 a as well in the vicinity of the Grewihdegänge 100 or inclined surfaces 38, 42 are dimensioned.

The above description has been chosen with reference to an embodiment in which the container 22 or 22 a is a glass or a bottle. It is to be understood, however, that the composite lids formed in accordance with the invention can be placed on other containers in the same way. It can be either plastic containers or bottles as well as metallic cans.

It is generally preferred that the closure caps and rings be made of plastics such as thermoplastic materials

109843/1077

■ molded, which borrows greatly from injection molding processes can be processed. However, there are others too Materials, for example thermosetting plastics, in

can be used in the same way as thermoplastics,

Composite lids, consisting of a ring and a closure cap and designed in accordance with the present invention, can be used and applied for numerous products, and they are also compatible with almost all goods in question. This applies both to the materials of the ring and to the material of the closure cap and, if provided, for the adhesive. A particular advantage of the invention consists in the fact that the thread passages are not formed on the container and that consequently no need beatehti this container in a Verpa ckungs- or filling machine or the like to orient in a particular way when the sealing operation is performed, because the ring can be pressed onto the duroh b ehälter together with the closure. | Put on the cap with which it forms a unit, but the end cap can then be removed by twisting it.

processing of the plastic bottles or glasses is required. A standard glass, which, for example, has a courage or the like. For receiving the ring, is just as useful as a multitude of other embodiments of different shapes, this also applies to different shapes of rings and caps, as long as it is ensured that ring and Containers are either standard designs or match. In other words that means a single shape The dimensions and shape of a glass are the same for the exemplary embodiment of the one designed according to the invention Cover according to Fig. 1-7 »as well as for the embodiment 8-14 as well as for further specifically developed and not explained exemplary embodiments.

Reference is now made to FIGS. 1 and 2. In this context it should be mentioned that a preferred Embodiment of the inventively designed composite lid the angle of inclination of the beveled edges 38 is not excessively large. Though the exact ^ incle, which is used in each case does not represent a critical factor of the invention, the angles can be used in both the The order of magnitude shown in the figures or slightly smaller angles are preferably used.
