Description

The present invention relates to a first container for storing a first product preparation ingredient, optionally a second container for storing at least one other product preparation ingredient, and an obstruction element for the first container. A closing device that closes the opening from the surroundings (environment), connecting the second container to the closing device and establishing a fluid connection between the first container and the second container. Containing a packing system for at least one product preparation ingredient. The invention also relates to a corresponding method for handling this product preparation ingredient. Such packing systems are often used to mix fluid product preparation ingredients that were initially stored separately, primarily with two- or multi-component product preparations. In such preparations, the individual ingredients are contraindicated in combination with each other due to their chemical composition, or react very chemically, so they are mixed only just before they are actually used. There is a need. The formulation and use of such multi-component products is known in principle, especially in the fields of cosmetics, pharmaceuticals, foods, detergents and cleaning agents.

For example, the German utility model DE 29721872 U1 describes an arrangement for connecting two containers, the purpose of which is to first mix the liquids stored separately in the container. The connection arrangements described here are particularly useful for mixing the individual components of the hair dye, the individual components are contraindicated with each other and should be stored separately in separate containers until actual use. Must. Mixing of the individual ingredients to form a ready-to-use hair dye is done shortly before use. For this purpose, the connection arrangement has two connecting elements, each of which can connect the associated container. The connecting elements form a flow path for fluid communication with the inside of each container. Further, the two channels are aligned with each other in the connection arrangement. Further, the connecting device has a control element arranged in one flow path so as to be movable between the first position and the second position. The flow path can be opened and closed according to the position of the control element. Therefore, depending on the position of the control element, the flow through the flow path and the flow through the entire connection arrangement can be enabled or blocked. In the initial state of the connection arrangement, the flow path is usually closed. To improve the sealing function, an additional plug is provided, which closes the flow path in the initial state of the connection arrangement. In use, the shiftable control element removes the plug and secures a flow path for fluid to pass through.

WO2007 / 111667 A2 describes another system with two containers for storing the contents of the two containers separately, in which the different container contents depend on the connecting device connecting the two containers. The thing can be mixed just before use. For this purpose, the connecting device has a valve arrangement that is movable between the closed and open positions. At the open valve position, a flow path in the connecting device that forms the fluid connection between the two vessels is secured. Therefore, at the valve opening position, the contents of the two containers can be mixed.

The packing system described above, in principle, allows different substances to be stored separately and mixed just before actual use, but the individual product preparation ingredients are stored separately and handled efficiently. Then, it is functionally insufficient. This is especially true when storing highly chemically reactive or dangerous substances in this type of packing system, for example. In this respect, the packing system described above is only suitable for handling very specific chemicals.

With this in mind, the challenge addressed by the present invention is a closed packing system for at least one product preparation ingredient that allows the safe storage and handling of product preparation ingredients consisting of as many different chemicals as possible. Is to provide. In particular, the packing system according to the invention should enable safe and convenient handling of chemically reactive or dangerous substances.

This problem is solved by a packing system for at least one product preparation ingredient according to claim 1. The entire packing system is then multifunctional, with a first container for storing the first product preparation ingredient and optionally a second container for storing at least one other product preparation ingredient. It is substantially equipped with a closing device. The closing device can seal the opening of the first container from the surroundings by the closing element. In this way, among other things, chemically reactive and dangerous substances can be safely stored in the first container. Due to the closed closure of the first container, the material components from the first container are not released to the surroundings, and the surrounding conditions such as humidity in the air and oxygen in the air are affected by the chemical reaction in the first container. It does not adversely affect the substance components inside. The occlusive device also comprises a connecting device for detachably connecting the second container to the occluded device to establish a fluid connection between the first container and the second container. The occlusive device is fluid only when the occluded device is completely connected to the second container by a connecting device, that is, between the first container and the second container, that is, the opening of the first container. Designed to achieve connectivity. Undesirable discharge of product preparation ingredients from the first container to the surroundings is thus effectively prevented. In fact, the product preparation component is discharged from the first container to the second container only after the connection is made. In this case, the obstruction element, which is originally a separate component, and the connecting device are irreversibly joined to form the obstruction device. In this way, the block element and the connecting device can be manufactured independently of each other, particularly easily, by a suitable method such as injection molding, and in a joined state, i.e., as a block device, a common structural unit. Can be treated advantageously. Joining of the blockage element to the connecting device can be done by a snap process or an equivalent joining step. In this case, the obstruction element and the connecting device are axially pressed against the axis of the obstruction device under the action of force and snap-fit in a substantially non-removable manner. Here, the non-removable connection between the obstruction element and the connecting device means that the two parts once connected cannot be removed from each other in a non-destructive manner.

In the present invention, the term "product preparation" or "product preparation component" should be understood to mean, in principle, a fluid and / or pourable substance. This includes all liquids, gels, pastes, or equivalent high viscosity materials with generally equivalent flow properties and all powders, particulates with generally equivalent flow or pouring properties. , Granular, or equivalent solid matter. Here, "product preparation" or "product preparation component" includes both individual chemical substances and mixtures of substances, respectively.

According to an advantageous embodiment of the packing system, the occluded element (ie, the entire occluded device) is non-removably connected to the first container by a fastening sleeve, except for its breakage. As used herein, "non-removable" means that the obstruction element or fastening sleeve cannot be removed from the first container in a non-destructive manner. The non-removable connection between the fastening sleeve and the first container is preferably achieved by a snap fit or a screw / snap fit combination. From the point of view of connection, the fastening sleeve can be snap-fitted to the first container, particularly advantageously. By being non-removably connected to the first container in this way, the occluder device provides highly reliable sealed storage of product preparation ingredients within the first container. This prevents the consumer from opening the first container and the product preparation ingredients from unintentionally leaking from the first container to the surroundings. Similarly, the product preparation ingredients stored in the first container are reliably protected from unwanted environmental effects such as humidity in the air and oxygen in the air as a result of the closure of the sealed container. In this respect, such packing systems can also store and handle highly chemically reactive and dangerous substances, in particular, in a first container.

It should be understood that the "container" in the content of the present invention means a container of various shapes, and these containers have a container wall in which the inside of the container has an opening for discharging the contents of the container. It is common in that it is surrounded by. The opening of the container can be opened or closed by a suitable closing element. Therefore, such containers can have a variety of designs. However, containers of design such as bottles, pouches, canisters, jars, tubes, etc. are particularly suitable. Regarding the material of the container, in order to protect the contents of the container according to the purpose of use, select a material that can obtain a sufficient barrier effect from the surroundings, especially against oxygen and humidity in the atmosphere, due to its physical characteristics. There is a need to. In addition, the container material should be designed to be sufficiently inert with respect to its chemical and physical reactivity with the container contents. Suitable plastics such as glass, PP and PTFE, or materials with equivalent properties, have proven to be suitable container materials that best meet the aforementioned requirements.

Similar conditions apply to the selection of the material of the occluder: the material of the occluder allows the occluder to have an appropriate barrier effect, especially against atmospheric oxygen and humidity, and the contents of the container. It is preferably designed to be chemically inert to the patient. Suitable plastics such as glass, PP and PTFE, or materials with equivalent properties, have proven to be suitable closure materials that best meet the aforementioned requirements.

To further improve the packing system, the obstruction element is provided with a cap for closing the first container, which in the initial state of the obstruction device is connected to the fastening sleeve of the obstruction element via a predetermined breakpoint. Will be done. The cap is designed so that, in principle, the opening for discharging the container contents from the first container can be closed and opened. When the container is closed, the cap is in contact with the first container, so that the opening is completely covered. In order to open the first container, the cap needs to be opened at least partially. For that purpose, it is necessary to separate the cap from the fastening sleeve which is irremovably connected to the first container at a predetermined breakpoint so that the closing device is in a usable state from the initial state. After separation, the cap can be moved relative to the fastening sleeve or the first container. The cap can then be removed from the first container by relative movement to open the opening of the container. In this way, the connection of the cap to the fastening sleeve via a predetermined breakpoint forms a kind of tamper-evidence occlusion, which favorably indicates the unused initial state of the first container by the occlusion device.

A useful embodiment of a packing system with a corresponding occlusive device is that the cap can be moved axially relative to the connecting device with respect to the axis of the occluded device and is centered on the axis. This is achieved by arranging it so that it is fixed against rotation. The shaft extends essentially toward the center of the substantially cylindrical or sleeve-shaped basic structure of the obstruction device. Of course, the corresponding placement of the cap with respect to the occluder device applies only to a limited extent to the initial state of the occluder device, and the cap is preferably integrally connected to the fastening sleeve via a predetermined breakpoint. .. That is, in the initial state, the cap is fixedly connected to the fastening sleeve of the closing device so that the cap cannot move or rotate in the axial direction with respect to the sleeve. Further, after being in use, i.e. separated from the fastening sleeve, the cap is arranged to be axially movable and limitedly rotatable with respect to the fastening sleeve. Compared to the connecting device, the cap is continuous, i.e., arranged to be axially movable, but fixed to rotation in both the initial and used states of the obstruction device. .. As a result of this particular arrangement, there is a unique interaction between the fastening sleeve, cap, and connecting device that results from the relative movement of the individual components from each other in the process of connecting the two containers. .. Specifically, since it is fixed to the rotation with respect to the connecting device, the cap follows the rotational movement of the connecting device. As a result, the cap can be separated from the fastening sleeve at a predetermined breakpoint during use, i.e., can rotate relative to the fastening sleeve. Even after the cap is separated from the fastening sleeve, the cap follows the rotational motion and the cap is axially movable with respect to both the fastening sleeve and the connecting device.

In another embodiment of the packing system, the connecting device has a threaded portion for screwing into a second container. In this way, the interaction of the corresponding threaded portion on the connecting device with the second container causes the connecting device to be screwed into the second container at the time of connection. This makes it possible to connect two containers that are particularly convenient to use. In an advantageous variant of the packing system of the present invention, the fastening sleeve and the connecting device each have at least one mutually corresponding stop element, which is such that the corresponding stop elements abut against each other. Only up to allow relative rotation around the axis of the fastening sleeve and closing device of the connecting device. The interconnected rotation stop elements of the fastening sleeve and the connecting device essentially limit the relative rotation between the fastening sleeve and the connecting device to a rotation range of about 360 °, i.e. about one rotation. Each rotating element is preferably designed as a rib, shoulder, protrusion, or other equivalent rotational stopping element. Overall, the corresponding rotation stop elements serve to allow the basic transmission of torque between the fastening sleeve and the connecting device during use, especially when the two corresponding rotation stop elements touch each other. Fulfill. Also, the fastening sleeve and the connecting device can rotate relative to each other within a limited range.

According to a further developed embodiment of the packing system, either the fastening sleeve or the connecting device has a start / stop and an ending stop due to relative rotation between the fastening sleeve and the connecting device about the axis of the closing device. As formed, it has at least two rotation stop elements that interact with at least one corresponding rotation stop of the connecting device or fastening sleeve. As a continuation of the variant where there is only one rotation stop element for each of the fastening sleeve and the connecting device, at least two rotation stopping elements are placed on the fastening sleeve or the connecting device to allow relative rotation between the two components. It can be limited to a precisely defined range of rotation. In this case, the two rotation stop elements interact with at least one corresponding rotation stop element on the other component to form a start stop and an end stop for relative rotation between the fastening sleeve and the connecting device. do. In this way, the range of values for relative rotation between the fastening sleeve and the connecting device can be accurately set to a rotation angle of less than 360 °. It has been shown that the preferred range of rotation angles between start and stop and end and stop is about 0 to 180 °, particularly preferably 0 to 90 °. These limited range of rotation angles ultimately also determine the maximum possible rotation of the cap with respect to the first vessel. In this regard, the maximum opening dimension of the cap or the maximum removal position of the cap with respect to the first container is also indirectly determined by this limited rotation angle. That is, when the end and stop of the corresponding rotation stop element, that is, when the upper limit of the rotation angle is reached, the maximum release position of the cap with respect to the first container is also reached. In this way, by properly setting the upper limit of the rotation angle, the cap does not completely disengage from the first container and is always screw-engaged with the first container in all usage conditions of the packing system. , Can be securely fixed.

In a useful embodiment of the packing system of the present invention, the cap is connected to the first container via a thread having a direction of rotation opposite to the direction of rotation of the thread of the connecting device. This embodiment is intended to finally establish a fluid connection between the first container and the second container in the process of connecting the two containers by screwing the connecting device into the second container. Provides a great usage advantage of being able to maintain a constant direction of rotation. For example, a clockwise screw is provided between the connecting device and the second container, while a counterclockwise screw is formed between the cap and the first container. Therefore, in the process of connection, it is possible to screw the first container with the closing device into the second container clockwise via the connection device. In this case, the first container rotates clockwise with respect to the second container together with the closing device. Continuing this relative rotation of the first and second vessels clockwise not only completes the connection, but at the same time the cap is separated from the fastening sleeve via a predetermined breakpoint and the cap is reversed. Will be released from the first container by the thread of. In a very simple and easy-to-use way, the reverse thread between the connecting device and the second container and between the cap and the first container ensures that the container is connected and that of the first container. As a result of opening, the fluid connection between the first container and the second container is set.

According to a preferred modification of the packing system of the present invention, the cap has a substantially pot-like main structure having a bottom wall and a cylindrical peripheral wall adjacent to the bottom wall. In this case, the peripheral wall of the cap is provided with at least one opening through which the fluid connection between the interconnected containers is final when the cap is sufficiently removed. Established in. Ideally, a plurality of openings are provided on the peripheral wall of the cap, and it is desirable that these openings are uniformly distributed on the circumference of the peripheral wall. At least one window-like opening in the peripheral wall of the cap allows the fluid connection to be set up even if the cap is only partially released from the first container. For this purpose, the opening of the cap peripheral wall is preferably located in the immediate vicinity of the cap base. Specifically, the cap is first due to a clockwise relative rotation between the first container or fastening sleeve that is secured to rotation and the second container or connecting device that includes the cap. It will be unscrewed from the container. If the cap is not fully screwed in but not completely released from the first vessel, an opening in the peripheral wall of the cap so that a fluid connection between the first and second vessels is established. The part is opened. In this state, the cap is partially released from the container but is connected to the first container via a thread in the opposite direction. In this case, a relative between the fastening sleeve and the connecting device is used so that the cap cannot be unscrewed from the first container until the opening in the peripheral wall of the cap is opened, using corresponding anti-rotating elements. It is especially useful to set the range of rotation values. The relative start / stop and end / stop of rotation between the fastening sleeve and the connecting device is set via the position of the rotation stop element, so that the cap unintentionally completely disengages from the first container. Can be prevented. Instead, the start and end stops ensure a permanent screw connection between the cap and the first container, regardless of the usage of the entire packing system or the opening of the first container.

In principle, the fluid connection between the two connected containers allows the product preparation ingredients stored in the first container to be placed, especially through the corresponding openings in the first container and cap. It can be transferred from one container to a second container reliably and without loss. At least, as mentioned above, for product preparation ingredients that are fluid or have corresponding pouring properties, the first container is held on top and is generally the result of gravity, i.e. automatic. Will be transferred. Alternatively or additionally, the transfer of the product preparation component can also be carried out by an external force acting on the deformable first container. This is applied, for example, to a pouch-shaped or tubular first container, and the product preparation component can be squeezed out of the first container and transferred to the second container.

In an alternative embodiment of the packing system, after the second container is connected to the first container by a occlusive device, the first product preparation component and at least one other product preparation component are mixed separately. Product preparation ingredients are stored in a second container. For this purpose, the two product preparation ingredients, which were initially stored separately in two containers, are first combined during the process of connecting the containers to form a fluid connection, and then mixed. To form a multi-component product preparation. The actual mixing is done by the rapid movement of the two connected containers. For this purpose, the user shakes, tilts, and rotates the two connecting vessels. In principle, such multi-component product preparation mixtures consist of individual product preparation ingredients that are initially chemically contraindicated with each other and are not uncommon. An example of such a multi-component product preparation mixture is a cosmetic product such as a multi-component hair color product. The advantage of the packing system of the present invention lies in its basic structure closed from the surroundings. That is, in this packing system, substances with high chemical reactivity and dangerous substances can be safely handled as individual product preparation components. Finally, the first product preparation ingredient is connected to the associated second container and can only be transferred from the first container if the first container is opened as intended and is optional. Can be transferred to for subsequent mixing with additional product preparation ingredients. The undesired release of the first product preparation component from the first container to the surroundings is effectively avoided by the multifunctional occlusion device of the present invention.

According to a further useful embodiment of the packing system, the occluder can be connected to the second container in a liquidtight manner. The occlusive device is then hermetically connected to the second container by a connecting device to ensure that undesired release of one or more fluidity and / or pourable product preparation components to the perimeter is avoided. Ru. In this way, a closed packing system is realized that ensures that the user does not come into contact with any of the product preparation ingredients being handled.

In a relatively developed variant of the packing system, the occluder device comprises at least one sealing element to ensure a liquid-tight connection to the first and / or second container. This type of sealing element can, in principle, have almost any geometric design and, in particular, can have an axial and / or radial sealing effect. In particular, the sealing element can be designed such as a sealing ring, a sealing lip and the like.

Protection is also sought for instructions for two alternative methods for handling at least one product preparation component using the packing system described above.

An alternative to the first method is used to ensure that at least one product preparation ingredient is transferred from the first container to the second container using a packaging system as described above. The packaging system here comprises a first container for storing at least one first product preparation ingredient, the opening of the first container being a closure fixedly connected to the first container. It is blocked from the surroundings by the obstruction element of the device. The obstruction element also comprises a cap that, in the initial state of the obstruction device, is connected to the fastening sleeve of the obstruction element via a predetermined breakpoint. The first container thus closed cannot be manually opened by the user. Further, the occlusive device is provided with a connecting device for connecting the second container to the occluded device and, in principle, allowing a fluid connection to be established between the first container and the second container. .. The blockage element, which was initially a separate component, and the connecting device are irreversibly connected to form the blocking device. Here, non-removable means that the two components cannot be destructively separated from each other after the connection process. Further, the connecting device is movable in the axial direction relative to the axis of the closing device, and is arranged so as to be fixed with respect to rotation about the axis. Further, the connecting device has a thread for screwing into the second container. In such packing systems, the following method sequence has been found to be useful for safely transferring product preparation ingredients from a first container to a second container without unwanted release to the surroundings. There is. First, the first container is attached to the second container by a closing device, and specifically, the corresponding thread of the connecting device is engaged with the thread of the second container. Then, the closing device is screwed into the second container using the connecting device until the connection end position is reached between the connecting device and the second container. The connection end position means a state in which the connection device is completely screwed into the second container by a screw. In addition, the connecting device cannot be screwed into the second vessel any further, thus forming a stationary structural unit with the second vessel at least temporarily. Therefore, not only the occlusive device itself, but also the first container irremovably connected to it is connected to the second container at the same time. The relative rotation between the first container or occluder and the second container already used to screw in the occluder is then continued. This means that the first container rotates further with respect to the second container with the closing element while maintaining the clockwise screwing direction of the connecting device. The cap, which is initially connected to the fastening sleeve via a predetermined breakpoint and secured against rotation to the connecting device, is separated from the closing element or fastening sleeve at the predetermined breakpoint. Here, the separation of the cap at a predetermined breakpoint is such that as the relative rotation between the two connected vessels continues, the fastening sleeve follows the movement of the first vessel and the connecting device with the cap is second. Due to the fact that it follows the movement of the container in 2. After separating the cap from the fastening sleeve, the relative rotation between the first container or fastening sleeve and the second container with the connecting device is continued while maintaining the direction of rotation. The separated cap is connected to the first container by a thread having a rotation direction opposite to the thread of the connecting device. Therefore, the cap is simultaneously unscrewed from the first container as a result of the thread of the cap in the opposite direction as the relative rotation continues. For example, the thread between the connector and the second container is designed clockwise, and the thread between the cap and the first container is designed counterclockwise. Of course, opposite rotation directions are possible for both threads, but it is important that the two threads are oriented in opposite directions. Continued relative rotation removes the cap from the first container to the extent that it opens at least one opening in the peripheral wall of the pot-shaped cap. The opening of this cap overlaps the opening of the first container, thus providing a fluid connection between the first container and the second container. After the fluid connection between the two containers has been established, it is also possible to transfer at least one product preparation ingredient from the first container to the second container. Such movement of the product preparation component is preferably done as a result of gravity, with the first container being placed on top when the container is connected. Further, in the case of the first container, which is particularly flexibly designed, the transfer of the product can be supported by the action of an external force on the first container. This is preferably applied to the first tube-shaped or pouch-shaped container.

In principle, the above method is suitable for handling almost all possible product preparation ingredients. However, due to the blockage functionality of the packing system, which allows product transfer only after the two related containers are properly connected, it is used in connection with highly chemically reactive or dangerous substances. Is particularly advantageous. Moreover, the above-mentioned method can be universally used in a wide variety of application fields. To give a pure example, the transfer method according to the invention can be particularly advantageously used in all types of substance additions, refill processes from refill containers, additive additions, and equivalent substance transfer processes.

An alternative to the second method is to safely transfer at least one product preparation ingredient from the first container to the second container, as well as subsequently store the first product preparation ingredient in the second container. Helps to form a multi-component product preparation by mixing with other product preparation ingredients. Here, a packing system as described above is also used. Here, the packing system comprises a first container for storing at least one first product preparation ingredient, the opening of the first container being a closure fixedly connected to the first container. It is blocked from the surroundings by the obstruction element of the device. The obstruction element also comprises a cap that, in the initial state of the obstruction device, is connected to the fastening sleeve of the obstruction element via a predetermined breakpoint. The first container thus closed cannot be manually opened by the user. The packing system also comprises a second container for storing at least one other product preparation ingredient. Further, the closing device is provided with a connecting device for connecting the second container to the closing device and, in principle, allowing a fluid connection to be established between the first container and the second container. The blockage element and the connection device were initially separate components, but are non-removably connected to form the blockage device. Here, non-removable means that the two components cannot be separated from each other in a non-destructive manner after the connection process. Further, the connecting device is movable in the axial direction relative to the axis of the closing device, and is arranged so as to be fixed with respect to rotation about the axis. Further, the connecting device has a thread for screwing into the second container. In such a packing system, the product preparation component is safely transferred from the first container to the second container without unwanted release to the surroundings, and the component is further transferred to the product preparation component in the second container. It turns out that the following method sequence is useful for mixing with to form a multi-component product preparation. First, the first container is attached to the second container by a closing device by engaging the connecting device with the corresponding thread of the second container. Next, the closing device is screwed into the second container using the connecting device until the connection end position is reached between the connecting device and the second container. The connection end position represents a state in which the connection device is completely screwed into the second container by a screw. In addition, the connecting device cannot be screwed into the second vessel any further, thus forming a stationary structural unit with the second vessel, at least temporarily. Therefore, not only the occlusive device itself, but also the first container irremovably connected to it is connected to the second container at the same time. The relative rotation between the first container or occluder and the second container already used to screw in the occluder is then continued. This means that the first container rotates further with respect to the second container with the closing element while maintaining the clockwise screwing direction of the connecting device. The cap, which is initially connected to the fastening sleeve via a predetermined breakpoint and secured against rotation to the connecting device, is separated from the closing element or fastening sleeve at the predetermined breakpoint. Here, the separation of the cap at a predetermined breakpoint is such that as the relative rotation between the two connected vessels continues, the fastening sleeve follows the movement of the first vessel and the connecting device with the cap is second. Due to the fact that it follows the movement of the container in 2. After separating the cap from the fastening sleeve, the relative rotation between the first container or fastening sleeve and the second container with the connecting device is continued while maintaining the direction of rotation. The separated cap is connected to the first container by a thread having a rotation direction opposite to the thread of the connecting device. Therefore, the cap is simultaneously unscrewed from the first container as a result of the thread of the cap in the opposite direction as the relative rotation continues. For example, the thread between the connecting device and the second container is designed to be clockwise, and the thread between the cap and the first container is designed to be counterclockwise. Of course, it is possible that both threads are oriented in opposite directions of rotation, but it is important that the two threads are oriented in opposite directions. As a result of continued relative rotation, the cap is in turn unscrewed from the first container to the extent that at least one opening in the peripheral wall of the pot-shaped cap is opened. The opening of this cap overlaps the opening of the first container, thus providing a fluid connection between the first container and the second container. After the fluid connection between the two containers has been established, it is also possible to transfer at least one product preparation ingredient from the first container to the second container. The transfer of such product preparation ingredients is preferably done as a result of gravity, with the first container being placed on top when the containers are connected. Further, the movement of the product can be supported by the action of an external force on the first container, especially in the case of the flexiblely designed first container. This is preferably applied to the tube-shaped or pouch-shaped first container. After the first product preparation component has been transferred to the second container, the plurality of product preparation components can then be mixed in the second container to form a multi-component product preparation. The mixing is preferably shaken, rotated or similarly moved by the appropriate movement of the two connected containers. In particular, the mixing process of multiple product preparation ingredients is carried out with a continuous fluid connection between the two containers. This not only results in a very homogeneous mix of the various product preparation ingredients, but also ensures a complete mix of the product preparation ingredients, forming a multi-component product preparation. This ensures that the conserved quantity of the individual product preparation ingredients actually flows completely into the multi-component product preparation mixture. In this regard, mixing the entire amount of the product preparation ingredients also ensures that the defined and therefore often intended mixing ratios between the individual product preparation components are maintained at the same time.

Further, in this alternative of the second method, the particular design of the closed packing system also ensures the particularly safe handling of individual product preparation ingredients that may be important to the user. In principle, the mixing method described above is suitable for handling a large number of different product preparation ingredients that need to be further processed to form the mixture. In particular, such mixing methods are useful for individual product preparation ingredients that have high chemical reactivity with each other or with respect to environmental parameters and need to be separated from each other until actual use. Multi-component cosmetics such as hair color products are examples of such applications. Even if it is a dangerous substance by itself, it can be handled advantageously and safely depending on the mixing method because the packing system is a closed type. Further, the above mixing method can be used universally in various fields.

According to a particularly favorable development of the two method alternatives described above, a method for connecting and releasing the cap from the first container and at the same time establishing a fluid connection between the first container and the second container. The steps can be performed reversibly. If the relative directions of rotation used to connect the two vessels are reversed, the two connections should be reconnected, analogically, in the reverse order of the corresponding individual method steps already described above. Can be done. In principle, when the relative direction of rotation between two connected and fluidly connected containers is reversed, the cap is first tightened to the first container. At the same time, the axial movement of the cap with respect to the first container closes at least one opening in the peripheral wall of the cap, thereby breaking the fluid connection between the two containers and closing the first container again immediately. Be done. When the cap is completely screwed into the first container, the connecting device is unscrewed from the second container, specifically, when the reverse relative rotation continues, the connecting device is again in the second container. The screw is removed until it is completely released from. Such a reversible method allows the possibility of repeating the connection process, the fluid connection process, the transfer of the product preparation component, and optionally the mixing of a plurality of product preparation components at a desired frequency using the packing system according to the present invention. It opens. In addition, by appropriately subdividing and controlling the cap opening and closing process, the amount of transferred product preparation component can be influenced in a targeted manner, thus essentially the first product preparation component. A kind of weighing system for will be provided by this packing system. This, in an advantageous manner, leads to the expansion of the application fields of such a packing system. For example, in each connection process, it is conceivable to distribute a certain amount of product preparation component from the first container to the second container. In this way, it is also conceivable to weigh a specified amount of the product preparation component from the first container according to the application. In any case, such a reversible sequence of the method steps described above is possible in both the transfer method and the mixing method.

Another useful embodiment of the modification of the two mentioned methods is that the relative rotation between the fastening sleeve and the connecting device around the axis of the closing device is provided to the fastening sleeve and the connecting device. The fact that the rotation stop element is limited to a rotation range of less than 360 ° by the corresponding rotation stop element, and this rotation stop element allows relative rotation only between the start stop position and the end stop position of the corresponding rotation stop element. It arises from. As already mentioned, the two stop elements interact with at least one corresponding stop element on the other component to start and stop for relative rotation between the fastening sleeve and the connecting device. Form an end stop. In this way, the range of values for relative rotation between the fastening sleeve and the connecting device can be accurately set to a rotation angle of less than 360 °. It has been shown that the preferred range of rotation angles between start and stop and end and stop is about 0 to 180 °, particularly preferably 0 to 90 °. These limited range of rotation angles ultimately also determine the maximum possible rotation of the cap with respect to the first vessel. In this regard, the maximum opening dimension or maximum release position of the cap with respect to the first container is also indirectly determined by this limited rotation angle. That is, at the end point of the corresponding rotation stop element, that is, when the rotation angle upper limit is reached, the maximum release position of the cap on the first container is also reached. In this way, proper setting of the upper rotation angle ensures that the cap does not completely disengage from the first vessel and always screw-engages with the first vessel in all usage conditions of the packing system. Can be fixed to. The screw between the cap and the first vessel is also correspondingly to ensure that the cap is opened wide enough within the rotation angle range limited by the anti-rotation element, especially to establish a sufficient fluid connection. Must be designed. Specifically, not only is the screw designed in the direction opposite to the screw between the connecting device and the second container with respect to its direction of rotation, but the pitch of the screw is the connecting device and the second container. It is chosen to be significantly higher than the pitch of the screws between and. Due to the high pitch of the threads between the cap and the first vessel, the cap traveled a sufficient distance in the axial direction and oriented in the radial direction of the cap peripheral wall, despite the limited relative rotation. The opening can be sufficiently opened. The thread pitch design optimized in this regard ultimately provides sufficient axial open or closed movement within the start or end stop of the relative rotation between the obstruction element and the connecting device. Is done.

Further features of the present invention will also be described below with reference to the embodiments shown in the figure.
FIG. 1 is a perspective view showing an embodiment of individual components of a packing system. FIG. 2 shows the obstruction device of FIG. 1 in two perspective views. FIG. 3 shows two cross-sectional views of the block device of FIG. 1 in two different operating states. FIG. 4 shows two cross-sectional views of the packing system of FIG. 1 in two different operating states.

The embodiments shown in FIGS. 1 to 4 include a first container 10 for storing a first product preparation component (not shown here) and optionally at least one other second product preparation component. Shown is a packing system 1 comprising a second container 20 for storing (also not shown). The packing system 1 is used to safely transfer the first product preparation component from the first container 10 to the second container 20 in a controlled state. If there is another second product preparation component in the second container 20, the two product preparation components can be advantageously mixed to form a multi-component product preparation.

In addition to the two containers 10 and 20, the packing system 1 also includes a multifunctional closing device 3 that initially closes the first container 10 from the surroundings by the closing element 40. For reliable occlusion of the first container 10, the occlusion element 40 first attaches the fastening sleeve 41 to the first container 10 in a non-destructive and non-removable manner in a ready-to-use state. Be prepared. For this purpose, the fastening sleeve 41 is preferably snap-fitted to the first container 10 or is both screwed and snap-fitted. In any case, the fastening sleeve 41, which is non-removably connected to the first container 10, is fixed in the axial direction and the rotational direction with respect to the shaft 4 of the closing device 3, so that the first container 10 is fixed. Is fixed to. In addition to the fastening sleeve 41, the closing element 40 has a substantially pot-shaped cap 45, which is ready to use and seals the opening 11 of the first container 10. .. For this purpose, the cap 45 has a bottom wall 47 consisting of an annular sealing plug 48 capable of accurately fitting and closing the opening 11 of the first container 10. This ensures that the undesired release of the first product preparation component from the first container to the surroundings is prevented.

The closing device 3 connects the second container 20 to the closing device 3 and thus indirectly to the first container 10, and also intervenes with the closing device 3 to connect the first container 10 and the second container. A connecting device 30 is also provided to establish a fluid connection with the 20. For this purpose, the connecting device 30 has an annular main structure with a screw 31 intended to engage the corresponding screw 21 of the second container 20. Further, the connecting device 30 has an inner sleeve 32 that can interact with the cap 45 in conjunction with the cap 45.

In principle, the two components of the blockage device 3, namely the blockage element 40 and the connecting device 30, are initially designed as separate components, which can be easily manufactured independently of each other, for example by injection molding. There is an advantage that it can be done. In use, the obstruction element 40 and the connecting device 30 are joined together in a non-destructive and non-removable manner to form the obstruction device 3. This is preferably done by a snap connection, in which the closing element 40 and the connecting device 30 are axially snapped together. After snap fitting, the obstruction element 40 and the connecting device 30 are non-removably connected to form the obstruction device 3, thereby causing the obstruction device 3 to be non-removably connected, as also shown in FIGS. After that, it can be handled very easily. At the same time, the closing element 40 and the connecting device 30 are joined to each other in the closing device 3 so that a limited relative rotation around the axis 4 of the closing element 40 and the connecting device 30 is possible in principle. For this purpose, corresponding rotation stop elements 33, 43 are provided on the block element 40 and on the connecting device 30, and when these elements interact, the block element 40 is in use. The relative rotation between and the connecting device 30 is limited to a rotation angle range of less than 360 °. This corresponds to a rotation range of less than one rotation. In this case, the rotation stop elements 33, 43 are preferably designed as radial ribs or protrusions, but may have other suitable geometric designs. According to a particularly preferred embodiment, as in the illustrated embodiment (see FIG. 2), the plurality of rotation stop elements 33, 43 are dispersedly arranged on the circumference of the closing element 40 and / or the connecting device 30. ing. As a result, the rotation angle range for relative rotation between the obstruction element 40 and the connecting device 30 is further limited, eg, a rotation angle range of up to 180 °, particularly preferably up to 90 °. In this way, the desired degree of permissible relative rotation between the obstruction element 40 and the connecting device 30 is highly targeted through the positions of the rotation stop elements 33, 43 arranged on the circumference. It can be set by the shooting method. In particular, the interaction of the plurality of rotation stop elements 33 and 43 arranged on the circumference fixes the initial rotation stop position and the end rotation stop position between the closing element 40 and the connecting device 30 in a defined manner. be able to. This means that the defined relative rotation between the obstruction element 40 and the connecting device 30 is limited to a set limited rotation angle range between the initial rotation stop position and the end rotation stop position. do.

As already mentioned, in the initial state of the packing system 1, the blockage device 3 is non-removably attached to the first container 10 filled with the first product preparation component. Further, in this initial state, as can be seen from FIG. 2, the closing element 40 and the connecting device 30 are arranged with each other so that the cap 45 extends in conjunction with the inner sleeve 32 of the connecting device 30. As a result, the cap 45 is fixed to the rotation about the axis 4 of the closing device and is fixed to the connecting device 30 so that the cap 45 follows every rotation of the connecting device 30 around the shaft 4. To.

Further, the cap 45 has a substantially pot-shaped main structure, and specifically, in an initial state, extends around a bottom wall 47 covering the opening 11 of the first container 10 and a shaft 4. It is composed of a peripheral wall 49. The peripheral wall 49 is provided with a plurality of (three in this embodiment) radial openings 51 so that the bottom wall 48 is integrally connected to the peripheral wall 49 via the three bridges 50. It has become. Further, in the initial state, the cap 45 is integrally connected to the fastening sleeve 41 via a predetermined breakpoint 52. In the present embodiment, the predetermined breakpoints 52 are dispersedly arranged in the circumferential direction of the cap, and each of the predetermined breakpoints 52 is composed of a plurality of point-like connecting bridges extending between the fastening sleeve 41 and the peripheral wall 49 of the cap. .. Of course, within the meaning of the present invention, other suitable designs of predetermined breakpoints are also conceivable.

In order to improve the sealing effect, the occlusive device 3 preferably comprises at least one sealing element 34, 48, 53, 54, which may be in the occlusive device 3 itself or with the occlusive device first and first. / Or act between the second containers 10, 20. In the embodiment of the obstruction device 3 shown in FIGS. 1 to 4, a plurality of sealing elements 34, 48, 53, 54 are provided, and these elements are preferably a sealing lip, a sealing ring, and an annular seal plug. It is designed as such. These sealing elements 34, 48, 53, 54, in particular, both prevent product preparation components from being undesirably released from one of the containers 10 and 20 to the surroundings, such as atmospheric oxygen and air humidity. It forms a barrier to prevent the environmental impact of the product from adversely affecting the ingredients of the product preparation.

In general, such a substantially closed packing system 1 can be used in a particularly versatile manner for storing and processing a wide variety of product preparation ingredients or other chemicals. In particular, the packing system 1 allows the user to handle the product preparation ingredients in the container completely non-contact. Basically, the packing system 1 is a user-friendly transfer of the first product preparation component from the first container 10 to the second container 20 and into the first product preparation component and the second container 20. Allows both an additional second product preparation ingredient that was originally preserved and any subsequent mixing of. Even though the embodiments of packing system 1 shown are preferably designed to mix multi-component product preparations, the two essential handling alternatives to packing system 1 are: Will be explained in more detail in.

The process of container connection for handling at least the first product preparation component stored in the first container 10 is mainly shown in FIGS. 3-4. In order to connect the two containers 10 and 20, first, the first container 10 to which the closing device 3 is non-removably attached is placed upside down on the second container 20. This can be seen from FIG. 4 (left view), at least in principle. In this initial state, the cap 45 is completely screwed into the first container 10 via the mutual screw connection portions 12, 46, so that the opening 11 of the first container 10 is an annular sealing plug. It is blocked by 48. At the same time, the corresponding threads 21 and 31 on the second container 20 and on the connecting device 30 are attached to each other. After that, the first container 10 is rotated in the clockwise direction with respect to the second container 20 together with the closing device 3. The connecting device 30 is screwed into the corresponding thread 21 of the second container 20 via the thread 31 (clockwise in this embodiment). At this stage, this relative rotation in the direction of rotation is blocked by the corresponding interaction of the corresponding rotation stop elements 33, 43, so that the relative rotation between the obstruction element 40 and the connecting device 30 is not. The relative rotation between the first container 10 or the obstruction device 3 and the second container 20 continues until the connection termination position shown in the figure on the left side of FIG. 4 is reached. After that, the connecting device 30 is completely screwed into the second container 20, so that it is no longer possible to rotate the connecting device 30 clockwise, and the connecting device 30 is at least at this stage, the second container. Form a stationary structural unit with 20. At this connection end position, the connecting device 30 thus follows further movement of the second container 20 in the process of continuing the container connection. The two vessels 10 and 20 are basically connected to each other, but have already been used to screw in the closure device 3 after reaching the connection termination position where there is still no fluid connection between the containers 1 and 20. The relative rotation of the first container 10 or the closing device 3 and the second container 20 in the clockwise direction is continued. This means that the first container 10 is further rotated with respect to the second container 20 while maintaining the clockwise screwing direction of the connecting device 30 together with the closing element 40. In the process of this continuous rotational movement, the cap 45, which is first connected to the fastening sleeve 41 via a predetermined breakpoint 52 and is arranged to be fixed against rotation with respect to the connecting device 30, is a predetermined cap 45. At the breakpoint 52, it is separated from the closing element 40 or the fastening sleeve 41. Separation of the cap 45 at a predetermined breakpoint 52 here is such that the fastening sleeve 41 follows the rotational movement of the first vessel 10 as the relative rotation between the two connecting vessels 10 and 20 continues. On the other hand, it is done due to the fact that the connecting device 30 follows the rotational motion of the second container 20 together with the cap 45. When the defined torque threshold is exceeded, this breaks the predetermined breakpoint 52. It should be noted here that the torque required to break the predetermined breakpoint 52 is always greater than the torque required to screw the connecting device 30 into the second vessel 20. This is the only way to maintain the desired order of the individual method steps when connecting the two containers 10, 20.

After the cap 45 is separated from the fastening sleeve 41, the relative rotation between the first container 10 with the fastening sleeve 41 and the second container 20 with the connecting device 30 is the previous rotation direction. Will be continued while maintaining. The cap 45 separated here is connected to the corresponding thread 12 on the first container 10 by the thread 46, and the corresponding threads 12 and 46 on the first container 10 and the cap 45 are second. Has a rotation direction opposite to the rotation direction of the corresponding threads 21 and 31 on the container 20 or the connecting device 30 of the above. Therefore, the cap 45 is simultaneously unscrewed from the first container 10 as a result of the thread of the cap in the opposite direction as the relative rotation between the two containers 10 and 20 continues. For example, the corresponding threads 21 and 31 on the second container 20 and on the connecting device 30 are designed to be clockwise, while on the first container 10 and the cap 45 mutually. The corresponding threads 12, 46 are designed to be counterclockwise. Of course, for the threads 21, 31, 12, and 46, the opposite rotation directions are possible, but the pair of threads 21, 31, 12, and 46 that correspond to each other are oriented in opposite directions. Is decisive. As a result of continued relative rotation, this time the cap 45 is unscrewed from the first container 10 to the extent that at least one opening 51 provided in the peripheral wall 49 of the pot-shaped cap 45 is opened. Will be done. The plurality of openings 51 are preferably distributed on the circumference of the peripheral wall, and in the present embodiment, the three openings 51 are formed on the peripheral wall 49 of the cap. Since these cap openings 51 overlap with the opening 11 of the first container 10, a fluid connection is provided between the first container 10 and the second container 20. This condition in which a fluid connection is established between the vessels 10 and 20 is shown on the right side in each case, especially by FIGS. 3-4. After the fluid connection between the two containers 10 and 20 has been established, the transfer of at least one product preparation component from the first container 10 to the second container 20 can also be subsequently performed. Such transfer of fluid and / or pourable product preparation components (not shown here) is preferably such that the first container 10 is placed on top when the containers are connected and of gravity. It is done as a result. Further, the transfer of the product may be supported by the action of an external force on the first container 10, especially in the case of the flexiblely designed first container 10. This is preferably applied to the first container 10 which is designed in the shape of a tube or pouch.

The above-mentioned method for handling the packing system 1 according to the present invention also reveals its decisive advantage. The closed structure of the packing system 1 with respect to the surroundings ensures safe handling of the product preparation ingredients stored in the containers 10 and 20 under all circumstances. Therefore, manual removal of the contents from the first container 10 is not possible because the closing device 3 is fixed in a non-destructive and non-removable manner. Instead, in the initial state of the first container 10, the cap 45 (as shown in FIG. 2) is interlocked into the inner sleeve 32 of the connecting device 30 to protect it from external manual access. Has been done. As a result, the cap 45 cannot be released from the first container 10 without the closing device 3 interacting with the associated second container 20. Due to the above interactions, the cap 45 is released from the opening 11 of the first container 10 only when connected to the associated second container 20. Therefore, the fluid connection of the first container 10 is exclusively limited to the corresponding second container 20. Undesirable fluid connections between the first container 10 and its surroundings are eliminated by the particular design of the packing system. Thus, not only is the packing system 1 not tampered with in an advantageous manner, but it also results in the transfer of product preparation ingredients only within the closed packing system 1. In this way, for example, it is possible to prevent the substance from spilling in an undesired manner during transfer from one container to another. Ultimately, the closed packing system 1 prevents any contact between the user and the product preparation ingredients contained therein under all conditions of use.

The above procedure for establishing a fluid connection between the containers 10 and 20 by connecting the two containers 10 and 20 and opening the cap 45 is a first product preparation component from the first container 10 to the first. It is not just for transferring to the container 20 of 2. Alternatively, the packing system described above could be considered to mix the product preparations of multiple components. For this purpose, the first product preparation ingredient is stored in the first container 10 in the initial state, while at least one other product preparation ingredient is stored in the second container 20. In the initial state, the second container 20 is preferably closed from the surroundings by a removable closure (not shown here). When two containers 10, 20 are connected to each other and a corresponding fluid connection is established according to the method described above, the first product preparation component is generally with the other product preparation components in the second container 20. Can be combined. The first product preparation component is transferred from the first container 10 to the second container 20 as described. The two product preparation ingredients can then be mixed with each other in the connected and fluidly connected containers 10 and 20. For this purpose, the entire packing system 1 with the connected containers 10 and 20 preferably mixes the two product preparation components to form a multi-component product preparation that is as homogeneous as possible by kinematics. To be shaken, tilted, or moved as well. Ideally, the fluid connection between the containers 10 and 20 is maintained during the mixing process, which increases the available mixing space and both product preparation ingredients to produce the product preparation mixture. Is guaranteed to be used in its full amount.

As shown in FIGS. 3-4 (right side in each case), in use of the connected containers 10 and 20 and the packing system 1 with the fluid connection established between the containers, the cap 45. It can also be seen that is not completely released from the first container 10. The cap 45 is only released to the extent that the cap opening 51 is opened in the radial direction in order to establish a fluid connection between the containers 10 and 20. At this cap position, the thread 46 of the cap is still engaged with the corresponding thread 12 of the first container 10. This cap position is preferably deliberately set on the aforementioned rotation stop elements 33, 43 on the connecting device 30 and the closing element 40. The basic interaction between the start and end stop positions of the relative rotation defined by the rotation stop elements 33, 43 and the open and closed positions of the associated cap 45 has already been described above. Is. In particular, due to their interaction, the corresponding rotation stop elements 33, 43 define an end stop position for relative rotation between the connecting device 30 and the obstruction element 40. At this stage, since the connecting device 30 and the second container 20 and the closing element 40 and the first container 10 are fixedly connected, the relative rotation between the containers 10 and 20 is completed. It also becomes. In particular, this termination stop with the cap 45 correspondingly only partially released from the first container establishes a fluid connection for connecting the containers 10 and 20 and between the containers 10 and 20. It offers the advantage of being able to reversibly perform all the essential method steps to do so. If the first relative rotation direction used to connect the two containers 10, 20 is reversed, the two containers 10, 20 are analogically reversed in the order of the corresponding individual method steps already described above. You can disconnect again with. In principle, the relative rotation direction reversal between the two connected and fluidly connected containers 10 and 20 initially causes the cap 45 to be fastened to the first container 10. At the same time, the axial movement of the cap 45 with respect to the first container 10 closes the opening 51 of the cap peripheral wall 49, thereby breaking the fluid connection between the two containers 10 and 20 and the first container. 10 is closed again immediately. Here, the torque required to tighten the cap 45 by properly designing the respective screw parameters between the cap 45 and the first container 10 and between the connecting device 30 and the second container 20. However, it must be ensured that the torque is set to be less than the torque required to unscrew the connecting device 30. When the cap 45 is completely screwed into the first container 10, the connecting device 30 is unscrewed from the second container 20, specifically, when the reverse relative rotation continues, the connecting device 30 is re-screwed. The screws are unscrewed until they can be completely released from the second container 20. Such a reversible method can repeat the connection step, the fluid connection step, the transfer of the product preparation component, and optionally the mixing of a plurality of product preparation components as many times as desired by using the packing system 1 according to the present invention. It expands the sex. Furthermore, by appropriately subdividing and controlling the opening and closing process of the cap 45, the amount of transferred product preparation components can be influenced in a targeted manner, and thus essentially the first product preparation. A kind of weighing system for ingredients will be provided by the packing system. This, in an advantageous manner, leads to the expansion of the application fields of such a packing system 1. For example, it is conceivable to discharge only a certain amount of product preparation components from the first container 10 to the second container 20 during each connection process. In this way, depending on the application, it is also possible to measure the defined discharge amount of the product preparation component from the first container. In any case, such a reversible sequence of the method steps described above is possible in both the transfer method and the mixing method.

In principle, the methods described above are suitable for dealing with almost all possible fluid and / or pourable product preparation ingredients in the sense of the present invention. However, due to the occlusive functionality of the packing system 1, which allows product transfer only after the two related containers 10, 20 are properly connected, chemically reactive substances or, when considered individually, are dangerous. It is particularly advantageous to use in connection with potential substances. Moreover, the above-mentioned method can be universally used in a wide variety of application fields. To give a pure example, the transfer method according to the invention can be particularly advantageously used in all types of substance additions, refill processes from refill containers, additive additions, and equivalent substance transfer processes.

In addition, the particular design of the closed packing system 1 ensures the particularly safe handling of individual product preparation ingredients, which may be favorable to the user when a multi-component product preparation mixture is produced. .. In principle, the mixing method described above is suitable for handling a large number of different product preparation ingredients that will be further processed to form the mixture. In particular, such mixing methods are useful for individual product preparation components that are highly chemically reactive with each other and need to be separated from each other until actual use. Multi-component cosmetics, such as hair coloring products, are examples of such applications. Even if it is a dangerous substance by itself, it can be handled advantageously and safely depending on the mixing method because the packing system is a closed type. Further, the above mixing method can be used universally in various fields.
