Description
[0001] Adhesive packaging with an additional container
[0002] Technical area
[0003] The invention relates to an adhesive package comprising a cartridge and an additional container, as well as to a method for pretreating and / or bonding substrates, in particular automotive spare parts, specifically windshields, using this adhesive package. Furthermore, the invention relates to the use of this adhesive package for pretreating and / or bonding substrates, in particular automotive spare parts, specifically windshields.
[0004] State of the art
[0005] Adhesive packaging is well known in the art. It is used in a wide variety of industries, such as the automotive industry, aircraft construction, wood processing, and construction. Adhesive packaging can be used with cartridge guns, for example, by pushing the piston in the cartridge forward so that the adhesive is pressed out of the front of the cartridge. However, certain substrates, such as glass, require pre-treatment prior to bonding due to their smooth surfaces. This pre-treatment must be clean, dry, and free of grease, oil, dust, and contaminants. Such pre-treatments are used, for example, in the automotive industry, particularly in the area of car replacement glazing. To date, the materials required for pre-treating and / or bonding substrates can be purchased individually or in repair kits.
[0006] However, experience has shown that, despite the availability of repair kits, professionals sometimes forget to perform certain steps during the pretreatment and / or bonding process. For example, a professional in the field of car replacement glass must remember that they must pretreat the window before bonding, and that a special pretreatment agent is required for this. Since bonding itself can be performed without pretreatment, but results in subsequent quality losses, it can easily happen that pretreatment is forgotten.
[0007] Furthermore, additional packaging material such as cardboard and / or plastic is required for the packaging of repair kits, which leads to increased resource consumption.
[0008] There is therefore still a need for improved solutions.
[0009] Description of the invention
[0010] The object of the invention is therefore to provide a solution that at least mitigates the disadvantages present in the prior art. In particular, it is an object of the invention to provide an adhesive packaging that makes it easier for a specialist to consider all the steps involved in the pretreatment and / or bonding of substrates, particularly in the field of automotive replacement glazing. Furthermore, the object of the invention is to provide a method for pretreating and / or bonding substrates using such an adhesive packaging, as well as the use of this adhesive packaging.
[0011] These objects are achieved by the features of independent claim 1, the method of independent claim 14 and the use of independent claim 15.
[0012] The invention accordingly relates to an adhesive packaging comprising a cartridge and an additional container, wherein a) the cartridge has a housing with an inlet opening and an outlet opening, wherein the inlet opening is located in a first end section of the housing and is closed by a piston element that can be moved relative to the housing, and the outlet opening is located at a second end section of the housing that is opposite the first end section and wherein the housing contains adhesive in an intermediate section that lies between the piston element and the outlet opening, b) the additional container has an additional container wall as well as a cover surface and a base surface and wherein the additional container contains a pretreatment agent and c) the cartridge and the additional container are separably connected to one another in such a way that removal of the adhesive is not possible before the additional container is removed.
[0013] The base surface is understood to be the surface that forms the bottom of the additional container. The cover surface is understood to be the surface that lies parallel to the base surface and forms the ceiling of the additional container. The cover surface and base surface are in particular congruent with one another. The cover surface and / or the base surface are preferably made of plastic. In a particularly preferred embodiment, the cover surface and / or the base surface are designed as a film. In addition, the cover surface and / or the base surface can have an opening tab. The opening tab enables the specialist to open the additional container more easily and quickly. In a particularly preferred embodiment, the cover surface and / or the base surface are made of the same material as the additional container wall.
[0014] The inlet opening is located on the front side of the first end section of the housing. Furthermore, the inlet opening extends at least partially, in particular at least half, and especially completely, across the cross-section of the front side of the first end section of the housing. The inlet opening is closed by a piston element in such a way that the adhesive located in the intermediate section cannot escape from the inlet opening. Furthermore, the piston element is movable relative to the housing.
[0015] The outlet opening is located on the front side of the second end section of the housing. The diameter of the outlet opening is usually smaller, in particular no more than half the diameter, and especially no more than one-third the diameter of the inlet opening.
[0016] In a preferred embodiment, the outlet opening is an outlet nozzle, in particular an outlet nozzle with an external thread. The external thread serves, for example, to connect the outlet nozzle to a screw cap, wherein the screw cap has an internal thread complementary to the external thread of the outlet nozzle, and / or the external thread serves to attach an additional application nozzle.
[0017] In a particularly preferred embodiment, the outlet opening, in particular the outlet nozzle, is closed by a pierceable membrane. In particular, the membrane comprises metal and / or plastic.
[0018] The exit opening preferably has a round, in particular circular, cross-section. However, it is also possible for the cross-section of the exit opening to have a different shape, e.g., oval and / or slit-shaped.
[0019] The auxiliary reservoir can be connected to the cartridge at the first end and / or the second end of the housing. When the auxiliary reservoir is attached to the first end, it blocks access to the piston element. This prevents the piston element from being displaced and the adhesive from being forced out of the cartridge. When the auxiliary reservoir is attached to the second end, it blocks the outlet opening. This also prevents adhesive from escaping.
[0020] Because the auxiliary container connected to the cartridge prevents the adhesive from being removed, this signals to the technician that no adhesive needs to be applied at this point in the process. This prompts the technician to first detach the auxiliary container from the cartridge. Since the auxiliary container containing the pretreatment agent must be removed manually, it also reminds the technician that the pretreatment must be performed in the next step.
[0021] In a particularly preferred embodiment, there is a cavity within the housing between the piston element and the inlet opening.
[0022] This cavity provides storage space, e.g., for materials required in the pretreatment and / or bonding process. It also serves as a guide and / or stabilizing aid when using the cartridge with a cartridge gun. Particularly preferably, the additional container is positioned in the cartridge in such a way that the additional container is at least partially, in particular completely, accommodated in the cavity.
[0023] This provides better protection for the additional reservoir against external influences such as force or environmental factors, thus reducing quality losses during storage and / or transport. This solution also saves space, requiring less storage space and / or allowing more adhesive packages to be transported at once, thus reducing transport costs. A further advantage is that the additional reservoir, which is at least partially positioned within the cavity, further secures the piston element in the housing.
[0024] It is also possible for the housing to have an internal thread on its inside along at least part of the length of the cavity, and for the auxiliary reservoir wall to have an external thread complementary to the internal thread of the housing along at least part of its length. This allows the auxiliary reservoir to be screwed into the cartridge, making the connection more stable and / or preventing the auxiliary reservoir from falling off the cartridge.
[0025] However, it is also conceivable for the additional container to have a skirt on the top surface and / or the base surface, with the outer diameter of the skirt being larger than the outer diameter of the additional container wall. The additional container can thus be connected to the edge of the cartridge housing at the inlet and / or outlet openings. The connection can be glued, plugged, clamped, and / or screwed, for example. It is possible for part of the skirt to protrude into the cavity when attached and / or for another part of the skirt to be slipped over the housing.
[0026] In particular, the part of the additional container accommodated in the cavity has a shape complementary to that of the cartridge.
[0027] Complementary shapes between the additional container and the cavity make it possible to maximize the volume of the additional container. This allows the additional container to hold as much pretreatment agent as possible, which saves space, costs, and / or resources. However, it is also possible for the part of the additional container held in the cavity to have no complementary shape to the cartridge. For example, it is conceivable for the cavity to have an internal lining, in particular padding, which extends radially from the inner cavity wall in the direction of the central longitudinal axis of the cartridge so far that the additional container is positively connected to the lining. The side of the lining facing the additional container can have a complementary shape to the additional container.
[0028] In particular, the additional container is connected to the cartridge at the front side of the first end section and / or at the front side of the second end section, in particular in such a way that the additional container covers the inlet opening and / or the outlet opening.
[0029] This reduces the risk of adhesive leakage, e.g., due to force applied to the cartridge. The external shape of the additional container is particularly preferably similar to the external shape of the cartridge. In particular, the diameter of the additional container at its widest point is a maximum of 20%, particularly a maximum of 15%, and especially a maximum of 10%, wider than the diameter of the housing at its widest point. This solution offers extremely space-saving adhesive packaging, as the additional container is a kind of extension of the cartridge.
[0030] In a particularly preferred embodiment, the additional container has at one of its ends a radially outwardly extending edge whose outer diameter is larger than the outer diameter of the additional container wall.
[0031] This is advantageous because the additional container can be additionally attached to the first and / or second end section via the rim, which strengthens the connection. The rim can be attached by gluing, plugging, clamping, and / or screwing. The rim can be flush with the first and / or second end section.
[0032] It is also possible for the edge to have a thread for fastening the additional container to the first and / or second end section. It is also conceivable for one or more clamping elements, in particular clamping arms, to be located on the edge, which are positioned such that they protrude into the interior of the housing when the adhesive packaging is closed. The closed state of the adhesive packaging is understood to mean that the cartridge and the replacement container are connected to one another. The open state of the adhesive packaging is understood to mean that the cartridge and the replacement container are not connected to one another, i.e. that the replacement container is detached from the cartridge. The clamping elements connect the additional container and the housing in a force-fitting manner from the inside, so that the connection can be reclosed. If the clamping elements are designed as clamping arms, the longitudinal axis of the clamping arms preferably runs parallel to the longitudinal axis of the additional container.The clamping arms are preferably no longer than the length of the additional container, in particular half the length, and especially one-third the length. In particular, the clamping arms are positioned on the rim so that the long side of the clamping arms facing away from the center of the additional container and the outer edge of the rim are flush.
[0033] In particular, the additional container is additionally attached to the cartridge by a lid and / or a film.
[0034] Lids are understood to refer, in particular, to rigid packaging closures. Compared to lids, films are more flexible. A lid can deform or even break under a certain force, whereas films can bend under the same force and then automatically return to their original shape. Films are more elastic than lids. In other preferred embodiments, the lid has a circumferential skirt for additional attachment to the cartridge.
[0035] The lid and / or film reinforce the connection between the auxiliary reservoir and the cartridge. Furthermore, the lid and / or film provide additional protection against environmental influences, such as moisture and / or accidental damage to the auxiliary reservoir.
[0036] In particular, the cartridge and the additional container are connected to each other in a material, form and / or force-fitting manner, in particular they are glued, plugged, clamped and / or screwed.
[0037] A material-to-material connection has the advantage of also serving as a guarantee of integrity. This allows the specialist to quickly determine whether the adhesive packaging has already been used. A form-fit connection offers the advantage of being detachable. This means it is resealable and can be reattached for the desired duration in the event of unforeseen interruptions to the work process. A force-fit connection is advantageous because there is no play between the connecting parts. This results in a stable connection that cannot slip, which is particularly beneficial for transporting the adhesive packaging.
[0038] In a particularly preferred embodiment, the cartridge and the additional container are connected to one another in such a way that the additional container is partially placed over the first end region and / or the second end region of the cartridge by means of an apron.
[0039] The skirt is preferably molded onto the edge of the auxiliary container. It is possible for the skirt to have an internal thread, and the housing, at least partially, an external thread complementary to the skirt's internal thread. This allows the auxiliary container to be resealably screwed to the cartridge. Furthermore, a screw cap provides a stable connection between the auxiliary container and the housing, making it extremely unlikely that the auxiliary container will fall off, e.g., during transport and / or storage.
[0040] The outer diameter of the skirt is also larger than the outer diameter of the auxiliary tank wall. The auxiliary tank can thus be connected to the edge of the housing at the inlet and / or outlet via the skirt. The connection can be glued, plugged, clamped, and / or screwed, for example. It is possible for part of the skirt to protrude into the cavity when attached and / or for another part of the skirt to be fitted over the housing.
[0041] Particularly preferably, the cartridge and / or the additional container are cylindrical, in particular circular-cylindrical.
[0042] It has been shown that adhesive is easiest to remove from a cylindrical cartridge or to push it out using a piston.
[0043] However, other shapes are also possible, such as an oval shape. In particular, at least one, preferably two, additional containers are connected to the cartridge.
[0044] This has the advantage that the number of additional containers can be adapted to the adhesive packaging variants. This allows the amount of pretreatment and / or application agent to be varied. It is particularly advantageous to use two additional containers to provide the inlet and outlet openings with additional leak protection.
[0045] However, it is also possible to connect only one additional container to the cartridge.
[0046] In a particularly preferred embodiment, a gas-tight and / or liquid-tight separating surface, in particular a membrane, especially a perforated membrane, divides the additional container interior into at least two compartments, in particular into two compartments.
[0047] The separating surface makes it possible to package different materials, such as pretreatment agents, application agents, cleaning agents, and / or adhesion promoters, separately in the same additional container. This saves space, is environmentally friendly, and offers the advantage that the specialist has access to all the materials at once. It also saves time, as the specialist does not have to unpack different materials individually, but simply opens the additional container. Due to the liquid- and / or gas-tight properties of the separating surface, the additional container can be easily used for a wide variety of materials, even when products in the product range change.
[0048] Additionally or alternatively, the separation surface may also consist of gas- and / or liquid-tight flaps and / or sliding elements.
[0049] Particularly preferably, the additional container additionally contains an application agent, in particular a cloth, a sponge, a felt and / or a cotton ball.
[0050] An application medium is understood to be a utensil with which the pretreatment agent is applied to the substrate. The application medium can also be a brush and / or a special glove, for example. Because the additional container also contains an application medium, the specialist has everything they need to apply the pretreatment agent. This saves the specialist time by eliminating the need to organize and / or search for a suitable application medium. This ensures that all required materials are available, especially in hectic situations and / or when materials are scarce. It can also prevent the use of used and / or contaminated application materials, which could impair the quality of the pretreatment.
[0051] In particular, the pretreatment agent is present in a first compartment and the application agent is present in a second compartment.
[0052] A compartment is a defined space within the auxiliary container. The material in one compartment is not in contact with material in another compartment.
[0053] This ensures that the coating agent does not come into contact with the pretreatment agent before a certain time, preventing any possible quality deterioration.
[0054] It is also possible for the additional container to have more than two compartments. This is particularly advantageous if more than two different materials are to be accommodated in the additional container.
[0055] Furthermore, the first and / or second compartments can be enclosed from above by the cover surface and / or from below by the base surface. If the cover surface and / or the base surface of the additional container are at least partially, or in particular completely, removed, the first and / or second compartments can be open at these points. Under these circumstances, the specialist has access to the first and / or second compartment.
[0056] Furthermore, it is conceivable that a first and / or a second compartment on the floor and / or ceiling are closed by an additional surface that does not include the top surface and / or the base surface, so that the first and / or the second compartment are still closed after the top surface and / or the base surface are removed. For example, the top surface and / or the base surface can be removed without opening the first and / or the second compartment. The specialist can then decide whether the materials in the compartments should be exposed simultaneously and / or sequentially.
[0057] In a particularly preferred embodiment, the separating surface extends along the longitudinal axis of the additional container.
[0058] The separation surface extends continuously from the base to the cover. This has the advantage that the specialist has manual access to all compartments after opening the additional container. Depending on their needs, they can then decide which material should be removed and / or brought into contact with each other at what time. The additional container can be opened by removing the cover and / or the base of the additional container. The cover and / or the base can be in the form of a lid and / or a film.
[0059] It is also possible for the first and / or second compartment to be designed so that the interior tapers toward the interface. When the first and / or second compartment is compressed, the pressure from the taper acts on a smaller section of the interface. This causes the interface to yield more quickly. Thus, less force is required to open the interface.
[0060] In particular, the separating surface is spaced inwards from the additional tank wall.
[0061] The separation surface can divide the interior of the additional container into compartments of different sizes and / or equal size. This is advantageous because the compartment size can vary depending on the material quantity requirements.
[0062] Particularly preferably, the first compartment has the shape of a circular cylinder, a cuboid and / or a triangular prism.
[0063] This has the advantage that the shape of the first compartment can be tailored to the material it is intended to contain. This saves space and / or resources. In particular, the second compartment accommodates the first compartment within itself. In a particular embodiment, the additional container wall forms the outer wall of the second compartment. In particular, the top surfaces of the first and second compartments lie in a first plane and / or the base surfaces of the first and second compartments lie in a second plane, whereby the first and second planes are not on the same plane.
[0064] It is also possible that the first compartment has a different shape than the second compartment.
[0065] In particular, the first and / or the second compartment are at least partially, in particular completely, hollow.
[0066] In a particularly preferred embodiment, the separating surface has the shape of a circular cylinder surface, a cuboid surface and / or a surface of a triangular prism.
[0067] This has the advantage that the shape of the separation surface can be tailored to the materials present in the first and / or second compartment. This saves space and / or resources.
[0068] However, it is also possible that the separation surface has a different shape, such as that of an oval cylinder surface and / or a six-sided prism surface.
[0069] In particular, the separation surface has a similar external shape to the additional tank wall.
[0070] This allows the volume of the additional container to be used as optimally as possible.
[0071] However, it is also conceivable for the separating surface to have a different shape than the additional container wall. Depending on the material to be stored in the additional container, this can be advantageous.
[0072] In a very special embodiment, the separating surface has the shape of a plane.
[0073] A plane is defined as a flat, two-dimensional object. "Flat" means that for every two points, a straight line passing through them also lies entirely within the plane. This shape of the interface has the advantage that the interface can be spanned. This allows the tensile strength of the interface to be controlled and adapted to the desired conditions.
[0074] However, it is also possible that the separating surface has a different shape, e.g. the shape of a curved and / or a wavy surface.
[0075] In particular, the separation surface extends along the transverse axis of the additional container.
[0076] In particular, the separation surface extends continuously across the entire cross-sectional area of the additional container. The top surface and / or the base surface can take the form of a lid and / or a film.
[0077] Furthermore, it is possible that the first and / or second compartment are designed in such a way that the interior space tapers towards the separation surface.
[0078] In a particularly preferred embodiment, the first and / or the second compartment are compressible such that the application agent and the pretreatment agent can be brought into contact with each other.
[0079] In particular, the first and / or second compartments are compressed in such a way that the pressure within the first and / or second compartments becomes so great that the separation surface opens under the pressure. This creates a connection between the compartments bordering the separation surface, and the materials in the compartments can come into contact with each other.
[0080] In particular, the additional container has a pressing device on the top surface and / or the base surface.
[0081] The pressing device can be a component of the top surface, the base surface and / or the additional container wall and / or be attached as a separate part to the top surface, the base surface and / or the additional container wall, e.g. by welding and / or gluing. When the pressing device is actuated, pressure is built up in the first and / or second compartment, which is transferred to the separating surface so that the separating surface opens, e.g. by tearing it open, folding it open and / or sliding it open. This enables the materials from the various compartments to come into contact with one another. The pressing device can stand out visually from the top surface, the base surface and / or the additional container wall. It can be designed, for example, as a raised section and / or as a recessed section.
[0082] In particular, the pressing device has an elastic region.
[0083] This has the advantage that the pressing device can be moved relative to the top surface, base surface, and / or additional container wall. The pressing device is pressed toward the interior of the first and / or second compartment, exerting pressure on the material located in the first and / or second compartment. The elastic region allows the pressing device greater freedom of movement and / or reduces the risk of damage to the top surface, base surface, and / or additional container wall.
[0084] In particular, the cover surface, the base surface and / or the additional container wall of the additional container have an opening area, in particular an opening area with predetermined breaking points.
[0085] The opening region is preferably a component of the cover surface, the base surface, and / or the additional container wall. The opening region can be opened by the specialist, e.g., by pressing in, folding open, and / or tearing it off. The specialist can gain access to the first and / or second compartment through the opened opening region. Furthermore, the first and / or second compartment can be compressed by the pressure exerted on the opening region upon opening. By accessing the first and / or second compartment, the specialist can remove the pretreatment agent, the application agent, and / or the application agent impregnated with the pretreatment agent from the additional container.
[0086] In a special embodiment, the opening area has predetermined breaking points, particularly in the form of a tapered material. These predetermined breaking points can be pressed in to open at least part of the top surface and / or the base surface. This is particularly advantageous in hectic situations and allows the specialist to work more efficiently.
[0087] However, it is also conceivable that the opening area can be opened in a different way, e.g. by cutting and / or opening.
[0088] In a particularly preferred embodiment, the additional container contains an application means impregnated with pretreatment agent, in particular a cloth, a sponge, a felt and / or a cotton ball.
[0089] This eliminates the need to first apply the pretreatment to the application material, saving time. It also prevents the professional from accidentally coating the application material with the wrong pretreatment.
[0090] Particularly preferably, the additional container comprises or consists of a moisture-proof material, in particular of glass and / or aluminum.
[0091] This protects the pretreatment agent from humidity, which can reduce quality losses.
[0092] In a further preferred embodiment, the additional container comprises plastic.
[0093] This is advantageous because plastic is lightweight and inexpensive to produce.
[0094] Preferably, the entire auxiliary container is made of a single material. This simplifies recycling.
[0095] Furthermore, the invention relates to a method for pretreating and / or bonding substrates, in particular car spare parts, especially windshields, using an adhesive package, comprising the steps:
[0096] 1) Producing or providing an adhesive package as defined in any one of the preceding claims.
[0097] 2) Remove the additional container from the cartridge. 3) Pretreat a substrate
[0098] 4) Applying the adhesive to the substrate.
[0099] 5) Bonding the substrate to a second substrate.
[0100] Furthermore, the invention relates to the use of an adhesive packaging for pretreating and / or bonding substrates, in particular car spare parts, especially windshields.
[0101] Further advantageous embodiments and combinations of features of the invention emerge from the following detailed description and the entirety of the patent claims.
