Closure caps for two-component packaging systems

The invention relates to closure hats for two-component packaging systems. More specifically, the invention relates to a closure cap mentioned in the preamble of appended claim 1.

Two-component packaging systems are known in which the container containing the diluent has a sealing cap containing a concentrate. By handling the closure cap 10, the user can open the container containing the concentrate so that the concentrate and diluent mix with each other without the user coming into contact with the concentrate.

GB-PS-10 83 335 discloses a device for storing and mixing two components, in which a screw cap with a container in which the other component is closed is used as the closing cap. This container is formed as a small container with a flat bottom and placed on a collar extending radially from the bottom of the threaded cap to the filling opening. When the cap is screwed in, the container 'container' is held at a certain height in the neck of the bottle by means of an upper ring shoulder, while the lower edge of the collar tears off along the bottom of the container along the intended breaking line and. 25 allows the component placed in the bottle to be applied. in the text, the diluent is called mixing with a component already enclosed in a container - which in the application text is called a concentrate.

DE-GM 75 31 452 discloses a device similar to that described above, in which the part formed as a container of the closure cap consists of a cylindrical wall part extending to the bottle neck and closed at the top by a closure cap. ***. bottom and bottom-mounted base plate. The base plate is pressed against the wall part by means of a fastening part * · * · 35 starting from the bottom of the closing cap, so that a chamber closed from the outside is formed.

2 86398 These known closure caps have several disadvantages which affect the use value of the two-component package: - The components located next to each other in the container and the bottle are certainly not separated from each other. When the second component of the two-component system is, for example, liquids, such as plant protection product concentrates or diluents or other organic solvents or emulsifiers, a seal occurs especially at the intended seal between the collar and the container 10 or when closing the base plate and wall part.

In addition, some of the two-component packages known from the prior art can be opened simply by unscrewing the closure cap and the two components can be removed separately. However, the explicit purpose of two-component packages is often that only a ready-to-use mixture of both components can be taken out. Separation into individual components is contrary to the goal of safe use with a two-component package.

- In the closure caps known from the prior art, the container can only be made of certain materials, which, depending on the type of closure cap, can be different, in which case the rigidity of the base plate, used as sealing members. 25 clip-type stairs tightness or intended breaking point, severely limiting the choice of material for mechanical! *! in terms of material quantities.

* * According to the invention, there are provided two-component packaging systems which can avoid the disadvantages described above.

‘The objective is solved by a closure cap for two-component packaging, which is characterized by. which is set out in the characterizing part of the appended claim.

3 86398 The inner container can be unscrewed from the collar thread by means of the rotations of the closure cap or in which the inner container can be separated by the lower part of the collar formed as a pushing edge so that the container opens into the diluent placed in the bottle. In this case, in addition to the improvements required in connection with the state of the art, other advantageous effects are achieved within the framework of the task.

Preferred embodiments of the closure cap according to the invention are set out in the appended claims 10 2-8.

certain embodiments of closure caps according to the invention have been described in detail without limiting the scope of the invention to examples. In particular, it should be emphasized that the exemplary embodiments described in the individual embodiments of the individual elements can be easily transferred by a person skilled in the art to other embodiments of the closure caps according to the invention and used to solve the respective sub-problems.

Figure 1 illustrates an embodiment of a closure cap according to the invention, in which the cap can be screwed into the bottle neck with a 2 * 'thread, hereinafter referred to as a bottle thread 17. A thread placed in the collar 3 - hereinafter referred to as a collar thread 4 - holds the inner container 5 in the closure cap. A plurality of wing-like, outwardly extending resilient rotation barriers 6 are arranged on the outer casing surface 5 so that the outer edges of the rotation barriers 6 extend beyond the outer casing surfaces 18 of the inner container 5 and slide in the direction of rotation of the rotating neck 2.

5 86398 past the barriers 6 'by the ratchet principle, however, preventing rotation in the opposite direction.

The flexible rotation barriers 6 are best placed in the inner container 5 and in the shape of the faceted rotation barriers 6 '5 in the neck 2. This simplifies the manufacture of the bottles. In addition, when the bottle is used several times, the faster-wearing flexible rotation barriers 6 are placed in the inner container 5, which is used only once. In addition, with this arrangement, the space in the bottle neck-10 can be optimally utilized, i.e. the space between the outer jacket surfaces of the inner container and the inner wall of the bottle neck 2 can be limited to a narrow gap; this is especially the case when the lower part of the inner container tapers as shown in Fig. 1. In this way, it is possible to make the best possible use of the volume available in the inner container for the concentrate 1 in relation to the usable interior space of the bottleneck.

Fig. 2b schematically shows a cross-section of the bottle neck and the inner container at the height of the anti-rotation devices 6 and 6 '20.

By means of a combination of the bottle thread 17, the collar thread 4 and the unilateral anti-rotation devices 6, 6 ', the closure caps can be given various uses: The unilateral anti-rotation device 6 - which is located in the inner container 5 in Figures 1 to 25 and Figure 2 - is directed *. so as to prevent the direction of rotation which causes the inner container 5 to be unscrewed from the collar 3. The collar thread 4 • * · and the bottle thread 17 are further dimensioned relative to each other so that the inner container 5 can be rotated into or out of less revolutions than required for a complete closure. for rotation by means of the bottle thread 17.

.:. Given these conditions, the following are obtained:. possible combinations: '· "Collar thread 4 and bottle thread 17 have different:.” 35 directions of rotation, eg collar thread 4 = left-hand thread 6 86398 Slack thread and bottle thread 17 = right-hand thread: When the inner cap 5 containing the inner container 5 and concentrate 1 is screwed into place, from the collar thread and the concentrate 1 mixes with the diluent 14 5.

In the second case, the collar thread 4 and the bottle thread 17 have the same directions of rotation - for example each on the right-hand thread - so that the closure cap containing the inner container 5 and the concentrate 1 can be closed up to the stop - Fig. 2a shows this situation and when the closure cap is screwed in, the inner container 5 is unscrewed from the collar thread 4. The concentrate 1 mixes with the diluent 14 before the bottle is opened.

15 The combination of individual characteristics described above is particularly well suited to a security packaging system:

The manufacturer fills the concentrate 1 and the diluent 14 into the closure cap and the bottle, screws both parts together and provides the user with a fixed closed unit one. Since the concentrate 1 and the diluent 14 are mixed together when the bottle is opened before the contents are opened to remove the contents, the concentrate 1 cannot be obtained undiluted. This is of considerable importance, especially when packaging plant protection agent concentrates. The manufacturer may provide packages that provide plant protection product solutions or half-concentrates that are still dilutable and are only usable at the time of opening. Since the concentrate 1 and the diluent 14 are predetermined by the manufacturer, the user cannot misdelete 30a. In addition, it is particularly important that: in such packages, concentrate 1 cannot be taken out incorrectly diluted. The expression M is used. is used in the text of the application whenever it is possible to implement · a combination of elements according to the invention. *: 35 closure caps where the concentrate cannot be taken out

II

7 86398 undiluted, before the closure cap is first fastened against the neck and unscrewed from the neck as usual.

Closure hats with a removable inner container 5, 5 can also be provided with anti-rotation devices which prevent rotation in both directions.

The characteristics of this type of cap are clarified with reference to Figures 3 and 4:

FIG. According to Figure 3, the closure cap placed on the neck of the bottle 2 can consist of two parts. The first part 15 - hereinafter referred to as the pressure cap 15 is placed in the neck 2 and has a flange ribbon 20 in the base of the hat made to receive the bottom part having the collar 3 - hereinafter referred to as the weight base 16. The hole in the bottom of the print cap 15 is dimensioned 20 so that the inner container 5 screwed into the printing base can be pushed through the printing cap 15 into fixed contact with the printing base 16. Closure hats divided in this way are particularly well suited as safety closure hats.

The drawings of Figure 4 are explained in more detail. Filling and closing the system thus formed and the use according to the invention: Π At the manufacturer, the printing cap is first screwed into a bottle filled with diluent 14. In a separate step, the inner container 5 '· *: 30 filled with concentrate 1 is screwed tightly with the printing base and the printing cap 15 already above the bottleneck is inserted through the upper opening so that the rotation barriers 6 and 6' are zigzag relative to each other. ** · . like manner. The parts of the pressure closure device located on the printing cap 15 and the printing base 16 - matching flange members' · “· 35 20 and 19 - are made so as to be connected to each other • • · · ·« · • * 8 86 398 and cannot be opened from the outside.

The combination of the collar and the bottle thread 4 and 17 can have the following effects: 5 The collar thread 4 and the bottle thread 17 run in the same direction:

When the closure cap is screwed in place, the inner container 5 is at the same time unscrewed from the collar thread 4, and the concentrate 1 mixes with the diluent 14 before the bottle 10 is opened.

It is particularly advantageous to combine threads with different directions of rotation, for example collar thread = left-handed 4 and bottle thread = right-handed 17.

The bottle thread is then formed in such a way that in the lowest position (closed position) it can be further rotated freely in the closed direction. Such threads are in accordance with the state of the art. This can easily be accomplished, for example, by placing a complete thread in the neck 2, while the lower cap only has a plurality of radially spaced ridge 21 at its lower part 20 which, when closed in the closed position, run freely in the lower thread of the bottle: at the bottom of the thread .The rotational movements made to open the closing cap cause, due to the obstacles of rotation 6 and 6 '“! that the "rotational movement in the closing direction" is transferred to the collar thread 4. When the inner container 5 is firmly on the collar 3, the "· · * closing cap cannot thus be unscrewed. Rather, deliberate rotation of the closing cap further in the closing direction is required until the inner container 5 is unscrewed. from cup V 3. Only then is the path open to open the bottle,.:. i.e. to unscrew the cap.

"···. A safety closure hat operating on the principle described above need not be manufactured in a divided embodiment 35 (i.e., a printing cap 15 and a printing base 16).

9 86398

In modern packaging technology, closure caps are also possible, in which the inner container 5 containing the concentrate 1 is provided with rigid rotation barriers 6, 6 'and which is already screwed onto the closure collar thread 4, presses vertically or slightly over the neck so that the closure is tight without this over-pressing prevents the rotation barriers 6, 6 '. Dividable closure caps, on the other hand, have several advantages: - It can be manufactured using only a small pressing pressure 10 when the printing base 16 is pressed into place and

In the case of closure hats with collar and bottle threads running in opposite directions or with collar and bottle threads having different thread pitches, expensive partitioning tools must be used in the injection molding process to produce indivisible closure caps. Due to the different threads of the bottle and collar threads 17, 4, the workpiece simply cannot be rotated out of the mold. In contrast, it is easily possible to manufacture the closure cap parts separately, in which the collar thread 4 and the bottle thread 17 are · '·.! and then joining the two parts, for example by sealing.

If desired, the connection of the pressure barrier 19, 20 can be sealed with hydrophobic auxiliaries, such as silicones, for example, or welded by means of heat treatment.

In order to improve the tightness, one or more sealing lips 23 can be placed above the cylinder thread 23 in the upper part of the closure cap. The invention also encompasses closure caps for two-component systems with an inner container 11 which can be divided into parts by means of rotational movements. .

; / * i 35 ίο 86 398

In the closure-closed inner container known from GB-PS 10 83 335, a divisible inner container is inserted over the smooth cylindrical shell of the collar. Even when using sealing lips made of clip-type steps, it is absolutely not possible to keep the concentrate enclosed in the inner container inside. Concentrates, such as plant protection product concentrates, generally contain a large amount of emulsifier and / or solvent with good dissolution properties. Partly due to the capillary action, the concentrate rises to the sealing surface between the inner container and the collar. This leak point cannot be removed with the sealing lips in this area or by using sealing rings. In addition, the concentrate is in constant contact with the breaking point entering the inner tank. 15 The plastic swells and the mechanical properties of the future breaking point change. Moreover, even at a short-term elevated storage temperature, the easily volatile solvent coronates of the concentrate can create such a high internal pressure in the container that the inner container detaches from the collar. Nor can this problem be solved in the manner known from DE-GM 75 31 452.

Leakage problems become particularly difficult when the connection between the base plate and the wall element made by means of clip-type steps must not be tight, because otherwise the base plate would not fall off when the closing piece is opened.

When the container can be opened when the inner container 5 is unscrewed from the collar thread 4 with the closing caps with the screw-on inner container described above, in another variant according to the invention with a divisible inner container, the inner container 11 must be further screwed onto the collar thread 4, . The functional lower part 7 breaks the inner container 11, whereby the separation takes place best along the thinning of the wall of the inner container 35 marked as a breaking point 10. It is particularly important compared to the technical level of the material 86 398 that the collar clamp 4 also acts as a sealing member.

The collar thread 4, the bottle thread 17 and the rotation barriers 6, 6 'can again be used in different ways 5 combined with each other in closure caps with a divisible inner container.

In the embodiment illustrated in Figure 5, the collar thread 4 and the bottle thread 7 have the same direction of rotation and the same pitch. The anti-rotation device is a ring shoulder 12 extending radially outwards from the upper end 10 of the inner container, which is dimensioned so as to rest on the upper edge of the neck 2. In the temporary closing position (Fig. 5a), the closure cap containing the concentrate is screwed on so far that the ring shoulder 12 is on the neck of the bottle. As the closure cap 15 is further rotated in the closure direction, the inner container 11 wraps more tightly over the collar thread 4 so that the lower part formed as the pushing edge 7 of the collar 3 breaks the inner container 11 along the breaking point 10 and thus opens the diluent 14 (Fig. 5b).

The annular shoulder 12, which, when the bottle is temporarily or permanently closed (Fig. 5a, Fig. 5b), simultaneously acts as a seal and an anti-rotation device, can prevent: * ·. * Rotation of the inner container 11 only by compressive pressure on its abutment surface. Ring shoulder 12 and bottle. ···. However, the abutment surface between the upper edge of the neck 2 can also be provided with tongs, notches or teeth 13 so that the free rotation of the inner container 11 is prevented by already low or non-existent compression pressure.

The inner container 30 11 screwed into place with the collar 3 sits so tightly on the collar 3 under the action of the collar thread 4 that sealing rings 24 can be used to seal the inner container. When stored, the concentrate 1 cannot affect the rupture point 10 and swell and the volatile components 35 of the concentrate from the collar 3 by creating a high pressure.

i2 86 398

Fig. 6 and Fig. 7 show embodiments of closure caps according to the invention with a divisible inner container 11. In these closure caps rotation barriers 6 and 6 ', as already thoroughly explained above, are placed on the outer jacket surface of the inner container 11 and on either side of the bottle neck 2 (Fig. 7d) or as an element preventing the direction of rotation (Fig. 7c).

In contrast to the embodiment of Figure 5, where the depth of suspension of the inner container is determined by the ring shoulder 12 resting on the neck of the bottle 2, in the embodiments shown in Figure 6 and Figure 7 the inner container can move freely vertically within the neck 2 corresponding to the collar thread 4. Thus, sul-15 pellets with a divisible inner container 11 can be provided, in which the collar thread 4 and the bottle thread 17 have different threads and / or pitches. In the following, the interaction of the individual parts by means of a two-part closure cap with a divisible inner container 11 is explained in more detail by way of example.

Figure 6 shows the individual parts separately:

A printing cap 15 with printing bases 16 to be printed thereon, in which: there is a collar 3 formed at the lower edge as a pushing edge 7,: which has a collar thread 4 made for receiving the inner container 11.

Figure 6 also shows two embodiments of a flat-bottomed divisible inner container 11 with a tubular base 25 tapering along the annular step 9 and a neck 2 which receives a closure cap by means of a bottle thread 17. The inner container 11 and the neck 2 the anti-rotation devices are shown as rigid anti-rotation devices 6 and • V ·: 30 6 '.

::: The manufacturer first fills the bottle with diluent 14 and threads the pressure cap 15 into the filling opening 2 as shown in Figure 7a *! ". In the second step, the push base 16, which is screwed into the inner container 11 and contains the concentrate 35, is pushed vertically into the pressure cap 15.

II

13 86398 through the open bottom so that the edge members 19 and 20 formed as closure pieces engage each other. If desired, the pressure shut-off device can be protected against unauthorized opening by gluing or sealing. Figure 7b shows a ready-to-use closure cap on top of the neck 2. The closure cap does not necessarily have to consist of two parts, a printing base 16 and a printing cap 15. It can also be made in one piece and the bottle can then be closed by squeezing it tightly into place on the hip thread of the bottle. Such methods are in accordance with the state of the art in packaging and do not need further clarification. When the closure cap is pressed directly into its vertical position, it is recommended to use a lens-shaped sub-thread 21 placed in the closure cap, as shown in Fig. 15 in Fig. 3.

In Fig. 7b, the closure cap further secures the contents of the bottle against run-off by means of sealing lips in the pressure cap 15, the neck 2, the collar 3 or the inner container 11.

When the bottle thread 17 and the collar thread 4 have opposite directions of rotation, the closure cap is in place: when screwed in, the inner container 11 wraps more tightly in the collar. : 3 in the bottom 8 or ring stage 9 of the inner tank 11: v. the pushing edge 7 breaks the breaking line 10 intended along the inner container 11 and the concentrate 1 and the diluting device 14 "are already mixed before the closure cap is unscrewed.

A combination of collar and bottle threads 4, 17 running in parallel can also be implemented: From the closed position (Fig. 7b), intentional further rotation in the closing direction 30 is required to disintegrate the inner container 11, indicating a sudden decrease in the force applied to the user. This phenomenon occurs in all kier-y.V. ' with forages with a divisible inner container 11 and can be used as a reliable indication of mixing of concentrate 1 and 35 diluent 14.

• · »· * i4 $ 6,398

When the collar and bottle threads 4, 17 are parallel, the inner container can be unscrewed from the collar 3 using fewer turns than is required to fully open the bottle, the inner container 11 falls off even before the sul-5 has been completely unscrewed. Concentrate 1 and diluent 14 are mixed, and thus concentrate 1 cannot be taken out undiluted.

Both closure hats with opposite collar and bottle threads 4, 17 and closure hats with parallel-10 threads thus meet the requirements for a safety closure cap.

The invention further relates to closure hats with a separable inner container 11 and unilaterally acting rotation barriers 6, 6 '(Fig. 7d). The unilaterally acting rotation barrier 6, 6 ', which can be located both on the outer jacket surface of the inner container 11 (Fig. 7d) and on the inner jacket surface of the bottle neck 2, is arranged to prevent the collar thread closing direction but not the unwinding direction. Although one-way anti-rotation devices 20 may also have use in two-piece closure caps, the use of this anti-rotation portion is preferred in one-piece closure caps. When the collar and pul-. ·. : the hip threads are parallel, preventing the anti-rotation 6, 6 'from closing the closing cap. The inner container li is screwed 25 onto the collar 3 and is broken along the broken line 10 by means of the pushing edge 7.

Such closure caps meet the requirements for a two-component system, in which the closure cap containing the concentrate is separated from the bottle and the connection between the bottle and the closure cap is only performed by the end user.

· In the second embodiment, the collar and bottle threads 4, 17 have different directions of rotation. This shape meets the requirements for a safety cap system: * Γ The manufacturer rounds the cap containing concentrate 1: 35: 35 into a bottle already filled with diluent 14. Individual 86 398 semi-effective anti-rotation devices 6, 6 '(Figure 7d) this measure has no inhibitory effect, because when the threads are in different directions, the "closing" direction of rotation of the bottle thread 17 means non-closing 5 sliding of the flexible barriers 6 over the rotation barriers 6 'suitable with them. Only when the user opens the tightly closed bottle does the anti-rotation device 6, 6 'have a blocking effect, the inner container 11 wraps over the collar 3 and the pushing edge 7 breaks the intended breaking line 10 along the container.

An essential advantage of closure caps with a divisible inner container 11 without the ring shoulder 12 limiting the immersion depth is that the pitches of the bottle thread 17 and the collar thread 4 can be selected independently. In the two-component system known from GB-PS 10 83 335, a pusher edge of a collar having a size corresponding to the pitch of the bottle thread is screwed into the neck of the bottle. Since at the same time the annular shoulder resting on the bottle opening limits the immersion depth of the cup, only a limited pressure can be applied to the intended breaking point, which requires a sufficiently thin intended breaking point. In practice, however, sealing problems occur primarily at intended thin fractures. Since, according to the invention, the pitches of the collar and bottle threads 4, 17 can be selected independently, a considerably greater force 25 can be applied to the intended breaking point 10 by means of the pusher edge 7 using a collar thread 4 with a small pitch. breakage points also from thicker layers of material, which leads to a clear improvement in tightness.

One universal advantage of closure hats with a divisible inner container 11 is that after separating the base 8 or the bottom bath 25, the concentrate 1 enclosed in the container flows out without obstruction, i. the mixing of the concentrate 1 and the diluent 14 inevitably takes place without shaking. It is clear from the foregoing that, using the device according to the invention, two-component packaging systems with improved tightness, reliability and functionality can be produced.

The question of the choice of the container and the entire sealing cap material 5 can thus be solved taking into account the requirements of the concentrate and the diluent.

The inner container - one-piece - may be made of glass, ceramics, plastics, metals, cardboard or other materials, whereby the choice of material may be limited by the intended breaking point in those inner tanks in which this intended breaking point is located. Since the collar thread can also act as a sealing member, the choice of certain thread shapes and the use of seals can substantially improve the tightness compared to the past.
