Description

Closing caps for two-component packaging systems

The invention relates to closure caps for two-component packaging systems.

There are two-component packaging systems are known in which a Vessel containing diluent, a closure cap containing a concentrate wearing. The user can enter the concentrate by manipulating the cap Open containing reservoir so that concentrate and diluent come together Mix without the user coming into contact with the concentrate.

From GB-PS-10 83 335 is a device for storage and mixing two components known in which a screw cap is used as the closure cap which carries a reservoir in which the one component is enclosed. This reservoir is designed as a small pot with a flat bottom and on a radially pushed from the screw cap base in the filling opening reaching collar. When the cap is screwed in, the pot serving as a reservoir is opened by means of an upper Ring bead held at a certain height in the bottle neck, while the lower one Edge of the collar tears off the bottom of the potty along a predetermined breaking line and such a mixing of the components in the bottle in the application text diluent mentioned - with the component previously enclosed in the reservoir - in the registration text Called concentrate - made possible.

Furthermore, from DE-GM 75 31 452 a generic device has become known in which the part of the closure cap designed as a reservoir consists of a cylindrical wall element protruding into the bottle neck, which above you: ch the bottom of the cap and below by a clip-on base plate is completed. The base plate is by means of a starting from the closure cap base Holding element pressed against the wall element, so that a closed to the outside Chamber is created.

These known closure caps have several, the utility value Disadvantages of the two-component pack Those in the reservoir and bottle Components that are next to each other are not safely separated from each other. if e.g. liquids such as herbicide concentrates and a diluent or other organic solvents or emulsifiers as a component of the Two-component system are present, occur particularly at the predetermined breaking point on the closure between the collar and the reservoir or at the closure between the base plate and wall element Leakage problems.

- Furthermore, some of those known from the prior art can be used Two-component packs opened by simply unscrewing the cap and both components are removed separately from each other. Often, however, is determinative purpose of two-component packs that only the ready-to-use mixture of the two Components should be removed. A separation into the individual components contradicts this the safe use aimed for with the two-component pack - for the according to the prior art known closure caps, the reservoir can only from certain materials, which can be different depending on the type of cap, are made with the stiffness of the base plate, the tightness of the as Sealing elements used clip steps or the predetermined breaking point the choice of material severely restrict with regard to mechanical material sizes.

According to the invention, two-component packaging systems are proposed, in which the disadvantages outlined above can be avoided.

The object is achieved by a closure cap for two-component packs, containing a reservoir intended to receive a concentrate (1), thereby characterized, a) that the closure cap rotatable on the bottle neck (2) has a Collar extending radially from the bottom of the cap into the bottle neck (2) (3), and b) that the collar (3) through a collar thread (4) for receiving an inner container (5) containing the concentrate (1) is prepared, and c1) that between the outer wall of the inner container (5) and the inner wall of the bottle neck (2) a turnstile (6,6 ') is attached at one or more points, which the blocks free rotation of the inner container (5) in one or both directions of rotation, or c2) that the collar (3) is angular or pointed at its lower end as an abutting edge (7) is formed and on the bottom (8), or on one divisible by one Inner container (11) extending annular step (9) rests so that with further rotation of the inner container (11) screwed onto the collar thread (4) in the direction of closure of the collar thread (4) severed the inner container (11) along a predetermined breaking line (10) will, where c21)) the free rotation of the inner container (11) by one or more on the outer wall of the inner container (11) and on the inner wall of the bottle neck (2) attached turnstiles (6,6 ') in one or both directions is obstructed, or C2 2) the inner container (11) at its upper part a radial outwardly directed annular bead (12) resting on the bottle neck (2) haben'der defines the depth of attachment of the inner container (11) and, if desired the inner container (11) in its free rotation by means of knobs or notches (13) locks.

Through the interaction of the elements according to the invention mentioned here Closure caps can be realized in which the inner container serving as a reservoir (5) unscrewed from the collar thread (4) by rotating the cap (combination of elements a), b) and C1) or where the inner container (11) separated by the lower part of the collar (3) designed as an abutting edge (7) so that the reservoir becomes the diluent in the bottle (14) opens (combination of elements a), b) c2) and c2.1.) Or

C2.2.). In addition to those required in the context of the task, Improvements over the prior art also have further advantageous effects achieved.

In detail, certain embodiments of the invention Closure cap will be described without limiting the scope of the invention to the examples to restrict.

It should be particularly emphasized that in the individual embodiments described exemplary concretization of individual elements easily by a person skilled in the art transferred to other embodiments of the cap according to the invention and for Solution of the respective sub-problem can be used.

The closure cap according to the invention for two-component packaging systems is explained in more detail with reference to drawings.

Figure 1 describes an embodiment of the closure cap according to the invention, in which the cap through a thread - hereinafter referred to as bottle thread (17) - Can be screwed to the bottle neck (2).

The inner container (5) is secured by a thread assigned to the collar (3) - In the following called collar thread (4) held in the cap.

The outer surface of the inner container (5) are several wing-like outwardly extending flexible turnstiles (6) assigned so that the outer edge the turnstile (6) protrudes beyond the outer surface (18) of the inner container (5) and on the turnstiles (6 ') assigned to the bottle neck (2) in one direction of rotation slide past like a ratchet, in the opposite direction of rotation however lock.

The flexible turnstiles (6) are preferably the inner container (5) and the angular turnstiles (6 ') assigned to the bottle neck (2). This simplifies the manufacture of the bottle. In addition, if they are turned several times the bottle the faster-wearing flexible turnstiles (6) mostly only assigned once used inner container (5). Also with this arrangement the clear space in the bottle neck can be optimally used, i.e.

the space between the outer surface of the inner container and the inner wall of the bottle neck (2) can be restricted to a narrow gap; this is especially true when the lower section of the inner container is so tapers as shown in Figure 1.

This makes the best possible use of the inside container for the concentrate (1) available volume in relation to the usable interior space of the bottle neck possible.

Figure 2b shows a schematic representation of a cross section through Bottle neck and inner container at the height of the turnstiles (6) and (6 ').

By combining the elements bottle thread (17), collar thread (4) and unidirectional turnstile (6) (6 ') can lock caps with different Types of application can be realized: The one-way turnstile (6) -in figure 1 and Figure 2 associated with the inner container (5) is set up so that it has the Locks the direction of rotation that leads to unscrewing the inner container (5) from the collar (3).

Furthermore, collar threads (4) and bottle threads (17) are like this dimensioned to each other that the inner container (5) opens or closes with fewer turns. can be unscrewed than to completely screw the cap by means of the bottle thread (17) is required. Taking this into account The following combination options are available: Collar thread (4) and bottle threads (17) have different directions of rotation, e.g. collar thread (4) = Left-hand thread and bottle thread (17) = right-hand thread: When screwing down the The inner container (5) and the closure cap containing the concentrate (1) become the inner container (5) unscrewed from the collar thread (4) and the concentrate (1) mixes with it the diluent (14).

In the second case, the collar thread (4) and the bottle thread (17) have the same Direction of rotation - e.g. both right-hand thread - then the inner container (5) and the closure cap containing the concentrate (1) must be closed until it is firmly seated - Figure 2a shows this state - and when the cap is screwed on at the same time the inner container (5) is unscrewed from the collar thread (4).

The concentrate (1) mixes with the diluent (14) before the bottle is open.

The combination of the individual features described above is particularly suitable for a security packaging system: concentrate (1) and diluent (14) are filled by the manufacturer in the cap and bottle, both parts together screwed and offered to the consumer as a tightly closed unit. Because at Screw on concentrate (1) and diluent (14) are mixed together, The concentrate can be used before the bottle is opened to remove the contents (1) cannot be removed undiluted. This is especially true when it comes to packaging of pesticide concentrates of outstanding importance.

The manufacturer can offer packs if only at the time of Open the pack with the ready-to-use pesticide stock or one more Semi-concentrate to be diluted is produced.

Because the ratio of concentrate (1) and diluent (14) is specified by the manufacturer, incorrect dosages by the consumer are excluded. It is also of particular importance that the concentrate in such packaging (1) not improperly undiluted can be taken. The expression "Safety cap is always used in the registration text when through the combination of the elements according to the invention closure caps can be realized, in which the concentrate cannot be removed undiluted if the cap sits on the bottle neck beforehand and uses the usual manipulation of the bottle neck is unscrewed.

Sealing caps with an inner container (5) that can be unscrewed can also be used with Turnstiles, which block the rotation in both directions, be equipped.

The features of this type of closure cap are based on Figures 3 and Figure 4 explains: Figure 3 shows an inner container (5), the outer shell surface several radially outwardly facing webs are assigned as a turnstile (6). in the For this purpose, the bottle neck (2) is arranged as a turnstile (6 ') with concordant webs.

The closure cap assigned to the bottle neck (2) can, as in FIG 3 - consist of two parts. One part - in the following the impact cap (15) called - is assigned to the bottle neck (2) and has a for receiving the base part carrying the collar (3) - hereinafter referred to as the impact base (16) called - prepared edge element (20). The recess at the bottom of the The impact cap (15) is dimensioned so that it is screwed to the impact base Inner container (5) until the impact base (16) is firmly seated in the impact cap (15) can be pushed through.

Such divided caps are particularly suitable as safety caps.

The filling and sealing, as well as the intended use a system designed in this way is explained in more detail with reference to the drawings in Figure 4: At the manufacturer, the impact cap (15) is first placed on the one with the diluent (14) Filled bottle screwed on. In a separate operation, the The inner container (5) filled with the concentrate (1) is screwed tightly to the impact base (16) and through the upper opening of the impact cap, which is already seated on the bottle neck (15) inserted so that the turnstiles (6) and (6 ') are offset from one another. The parts of the impact closure assigned to the impact cap (15) and the impact base (16) -the mutually concordant edge elements (20) and (19) - are prepared so that After the bottom (16) has plunged into the cap (15), they are firmly connected to one another and cannot be opened from the outside.

By combining collar and bottle threads (4) and (T7), the following effects are achieved: collar thread (4) and bottle thread (17) run in the same direction: When you unscrew the cap, the inner container is at the same time (5) unscrewed from the collar thread (4) and the concentrate (1) mixes with the diluent (14) before the bottle is opened.

The combination of different threads is particularly advantageous Direction of rotation e.g. collar thread = left-hand thread (4) and bottle thread = right-hand thread (17).

The bottle thread is designed so that it is in the lowest Position (locking position) can be turned further in the locking direction empty. Such threads are state of the art. For example, it can easily do this be realized that the bottle neck (2) is assigned a full thread is, while the Vdrschlusskappe several radially in one only in its lower area Has a certain height arranged lenticular thread webs (21) that when screwing run empty in the closing direction at the lowest thread of the bottle thread and be guided by the thread webs (22) of the bottle neck (2) when opening.

Rotational movements to open the cap cause the result Turnstiles (6) and (6 ') that a § "rotary movement in the locking direction" on the collar thread (4) is transmitted.

If the inner container (5) is firmly seated on the collar (3) the closure cap can therefore not be unscrewed. Rather, it requires the willful Continue turning the cap in the direction of the closure until the inner container (5) is unscrewed from the collar (3). Only then is the way to open the bottle, i.e. for unscrewing the cap, released.

A safety cap that works according to the principle described above does not necessarily have to be in the split embodiment (i.e., bump cap (15) and impact base (16)) are produced. According to the state of modern packaging technology It is also possible to use closure caps in which the concentrate (1) containing Inner container (5) is provided with rigid turnstiles (6,6 ') and is already fixed with the collar thread (4) of the closure cap is screwed, vertically or under lighter Press the rotation on the neck of the bottle in such a way that a tight seal is achieved can be without the turnstiles (6,6 ') hindering the pressing.

Divisible caps, however, have several advantages: - It can can be worked with low contact pressure when the impact base (15) is impacted and - In the case of the closure caps with opposing collar and bottle threads or with collar and bottle threads with different thread strokes must be used for production Undivided sealing caps in the injection molding process, complex, divisible tools can be used. Because of the different degrees of use of bottle and collar threads (17), (4) the workpiece cannot simply be unscrewed from the mold. In contrast it is easily possible to use the collar thread (4) and the bottle thread (17) to produce bearing cap part separately and then both parts, about middle to connect a rebound lock.

The seam of the impact seal (19, 20) can, if desired, with hydrophobic auxiliaries, such as silicone or sealed by thermal Treatment to be welded.

To improve the tightness can in the upper part of the cap one or more sealing lips (23) are attached above the bottle thread be.

The invention also encompasses closure caps for two-component systems with an inner container (II) that can be divided by the rotary movements, specific embodiments of this type are illustrated in FIGS.

In the case of the closure cap known from GB-PS 10 83 335, the divisible inner container attached to the smooth cylindrical jacket of the collar. Even when using sealing lips designed as clip steps, this can be done in the inner container enclosed concentrate cannot be kept absolutely safe. Concentrates, like Plant protection concentrates, for example, usually contain a high proportion of Emulsifier and / or a solvent with good Sol vatati onsei properties.

The concentrate rises partly due to capillary action on the sealing surface between the inner container and the collar. This leak can neither by sealing lips in this area nor by inserting sealing rings be turned off. In addition, the concentrate is in constant contact with the predetermined breaking point of the inner container.

The plastic swells and the predetermined breaking point becomes mechanical Properties changed. In addition, if the storage temperature is only briefly increased, Due to the volatile solvent content in the concentrate, such a high Build up internal pressure in the reservoir so that the inner container sits on the collar is loosened.

This problem also does not arise with the one known from DE-GM 75 31 452 solved.

The leakage problems are particularly noticeable here because the Connection between floor slab and wall element made by means of clip steps may not have a tight seal, otherwise the base plate when opening the The clasp would not fall off.

While with the previously described, with an inner container that can be unscrewed equipped, closure caps, the reservoir is then opened when the inner container (5) is unscrewed from the collar thread (4), must in the second according to the invention Variant with divisible inner container, the inner container (11) continues on the collar thread (4) are screwed on, so that the lower part of the Collar (3) separates the inner container (11), the separation preferably along a tapering of the inner container wall designated as a predetermined breaking point (10) happens. It should be emphasized as particularly important compared to the state of the art that the collar thread (4) also serves as a sealing element.

Collar thread (4), bottle thread (17) and turnstile (6.6 ') can again differently combined with each other for closure caps with divisible Inner containers are used.

In the embodiment described in Figure 5 have collar threads (4i and bottle thread (17) have the same direction of rotation and the same pitch A turnstile is used that extends radially outward from the upper end of the inner container Annular bead (12) which is dimensioned so that it sits on the upper edge of the bottle neck (2) rests. In the provisional closed position (FIG. 5a) this is the concentrate containing cap screwed so far that the annular bead (12) on the bottle neck rests. By further turning the cap in the direction of the closure the inner container (11) screwed more tightly onto the collar thread (4) so that the the lower part of the collar (3) designed as an abutting edge (7) the inner container (11) along the predetermined breaking point t10) and the reservoir becomes a diluent (14) opens (Figure 5b).

The annular bead (12), which in the case of temporary or permanent closure the bottle (Figure 5a, Figure 5b) serves as a seal and a turnstile at the same time, can on the one hand, the rotatability of the inner container (11) solely through the on its Block effective contact pressure. It is also possible to use the support surface between the annular bead (12) and the upper edge of the bottle neck (2) with knobs, Notches or prongs (13) equip that the free rotation of the inner container (11) is blocked with little or no contact pressure.

The inner container (11) screwed to the collar (3) sits through the collar thread (4) so tightly on the collar (3) that to seal the inner container Sealing rings (24) can be inserted. Neither can the concentrate (1) in the Storage act on the predetermined breaking point (10) and this swell, still can Volatile components in the concentrate due to the formation of a high internal pressure Loosen the seat of the inner container (11) on the collar (3).

FIG. 6 and FIG. 7 show embodiments of closure caps according to the invention with a divisible inner container (11), in which the turnstiles (6) and (6 ') as already has been explained in detail, on the outer surface of the inner container (11) and on the inner surface of the bottle neck (2) as one-sided (Figure 7d) or as both directions of rotation (Figure 7c) are arranged locking element.

In contrast to the embodiment discussed in FIG the depth of hanging of the inner container through the one resting on the bottle neck (2) Annular bead (12) is defined, the inner container is in the in Figure 6 and Figure 7 shown embodiments corresponding to the stroke of the collar thread (4) in the vertical Freely movable direction inside the bottle neck (2).

Thus, closure caps with a divisible inner container (11) can be used Are provided where collar threads (4) and bottle threads (17) have different mobility and / or incline. The interaction of the individual elements is an example using a two-part closure cap with a divisible inner container (11) explained in more detail.

FIG. 6 shows the individual elements spatially separated: impact cap (15) with a rebound base (16) which can be rebounded in it and which has the at its lower Edge designed as an abutting edge (7) collar (3) for receiving the inner container (11) has prepared collar thread (4), as well as two embodiments of one divisible inner container with a flat bottom (11) and with a along a ring step (9) tapering trough-shaped base (25) and the one for receiving the closure cap bottle neck (2) prepared by means of a bottle thread (17). The inner container (11) and the turnstiles assigned to the bottle neck (2) are designed as rigid turnstiles (6) and (6 ') shown.

The manufacturer first fills the bottle with the diluent (14) and screwed the impact cap (15) to the filling opening (2), as shown in FIG 7a shown.

In a second step, the one with the inner container (11) is screwed and the concentrate (1) containing Eihpreilboden (16) vertically through the upward open bottom of the Einprellkappe (15) inserted so that the formed as a closure Engage the edge elements (19) and (20). If desired, the impact closure be protected against unauthorized opening by gluing or sealing.

FIG. 7b shows the ready-to-use, seated on the bottle neck (2) Sealing cap. The closure cap does not necessarily have to consist of the two parts The impact base (16) and the impact cap (15) can also be made in one piece be manufactured and then the bottle by pressing until it is firmly seated on the Bottle threads are closed. Such methods are state of the art in packaging technology and do not need to be explained in more detail. With direct vertical pressing the closure cap is a lenticular Te; 1 thread associated with the closure cap (21), as shown in Figure 3, is preferred.

The closure cap shown in FIG. 7b in a ready-to-use state can if required by sealing lips on the impact cap (15), bottle neck (2), Collar (3) or inner container (11) also prevent the contents of the bottle from leaking out secured.

Wen bottle thread (17) and collar thread (4) opposite direction of rotation then the inner container (11) becomes tighter when the cap is screwed on screwed to the collar (3), which is on the bottom (8) or on the ring step (9) The abutting edge (7) on the inner container (11) separates the inner container (11) Mix along the predetermined breaking line (10) and concentrate (1) and diluent (14) before the cap is unscrewed. The combination of like-minded running collar and bottle threads (4), (17) can also be realized: Off the closed position (Figure 7b) requires the willful further screwing in the closing direction in order to divide the inner container (11), which the consumer, by a sudden decrease in the force required to turn. This effect occurs with all screw caps with a divisible inner container (11) and can be used as a reliable indicator that the concentrate (1) and the diluent have been mixed (14) to be taken If with collar and bottle threads in the same direction (4) (17) the inner container can be unscrewed from the collar (3) with fewer turns, than is required to fully open the bottle, the inner container falls (11) Take off concentrate before completely unscrewing the cap (1) and diluent (14) mix and the concentrate (1) can thus not be taken undiluted.

Thus both closure caps with opposing collar and Bottle thread (4) (17) as well as closure caps with co-rotating threads Requirements to be met by a safety cap.

There are also sealing caps with a separable inner container (11) and one-way turnstiles (6,6 ') (Figure 7d) are the subject of the invention. The one-way turnstile (6,6 '), both on the outer surface of the inner container (11) (Figure 7d) as well as on the inner surface of the bottle neck (2) can be attached is locking to the locking direction of the collar thread (4) and arranged in a non-blocking manner in relation to the unscrewing direction.

Although one-sided turnstiles are also used with two-part locking caps Can find application, the use of this turnstile element with one-piece Closure caps preferred. Locks when the collar and bottle threads are in the same direction the turnstile (6,6 ') when screwing the cap.

The inner container (11) is screwed onto the collar (3) and by means of the joint edge (7) is severed along the predetermined breaking line (10).

Such closure caps meet the requirements of a two-component system, in which the closure cap containing the concentrate is sold separately from the bottle and the union of bottle and cap only through the end user is made.

In another embodiment, collar and bottle threads have threads (4) (17) different directions of rotation. This form fulfills the requirements that a Safety cap system must be provided: The manufacturer screws the the concentrate (1) containing closure cap with a bottle in which the diluent (14) has already been filled in. The turnstile acting on one side (6,6 ') (Figure 7d) does not lock during this process, because the direction of rotation with uneven threads "Closing" the bottle thread (17) to a non-blocking sliding of the flexible Lock (6) via the concordant turnstile (6 ') means. Only when you open the tight closed bottles by the consumer locks the turnstile (6,6 '), the The inner container (11) is screwed onto the collar (3) and the abutting edge (7) is severed the reservoir along the predetermined breaking line (10).

A major advantage of sealing caps with a divisible inner container (11) without limitation of the hanging depth by an annular bead (12) consists in that the pitch of the bottle thread (17) and collar thread (4) are independent of each other can be chosen. In the two-component system known from GB-PS 10 83 335 becomes the abutting edge of the collar with a stroke of the bottle thread corresponding Amount screwed into the bottle neck.

Because at the same time the depth of hanging the cup through a hole on the bottle opening is limited to the annular bead on top, only limited pressure can be applied to the predetermined breaking point be exercised, which requires a reasonably thin predetermined breaking point.

In practice, however, predetermined breaking points that are too thin are preferred Leakage problems. Since according to the invention the pitch of the collar and bottle thread (4) (17) can be selected independently of one another by using a collar thread (4) with a low incline, a significantly greater force by means of the abutting edge (7) be exercised on the predetermined breaking point (10). Therefore, according to the invention, predetermined breaking points can can be made from thicker layers of material, which is a significant improvement the tightness leads.

A general advantage of sealing caps with a divisible inner container (11) is that after separating the bottom (8) or the bottom trough (25) in the reservoir Trapped concentrate (1) flows out unhindered, i.e. the concentrate mixes (1) and diluent (14) inevitably take place without shaking.

From all of the above it is clear that with the inventive Device two-component packing systems of the greatest tightness, safety of use and functionality can be established 1 bar.

The question of the choice of material for the reservoir and the entire sealing cap can therefore under the requirements specified by the concentrate and diluent to be drawn.

The - one-piece - inner container can be made of glass, ceramics, plastics, Metals, cardboard or other materials are made, with inner containers with predetermined breaking point, the predetermined breaking point can limit the choice of material. Through this, that the collar thread also serves as a sealing element, by choosing certain Thread forming and by inserting seals a significant improvement in Tightness can be achieved compared to the previously known.
