Definitions
- the invention relates to a method for closing a container according to the preamble of claim 1 and a closure serving this purpose according to the preamble of claim 11.
- containers such as bottles, canisters or the like are to be filled with a liquid in a filling operation and then closed with a closure
- the containers are first removed from a feed device, for example a magazine, and fed to a filling system by means of a conveyor device.
- a filling valve lowers over the mouth area of the container, through which the liquid is filled into the container.
- the filled container is then fed to a closing system, in which the mouth area of the container is closed with a closure likewise removed from a magazine and fed via a conveyor.
- the closure takes place in different ways.
- a closure blank is placed on the mouth region of the container and then attached to the by means of a shaping tool Mouth area of the container is adapted in shape, while in the case of a plastic closure, after it has been placed on the mouth area of the container, it is screwed onto the mouth area by means of a screwing tool.
- the method can also be used to fill containers with granular or powdery solids.
- both the containers and the closures are cleaned - or are already there - and possibly even disinfected before being introduced into the magazine, it cannot be avoided in the described method that the mouth region of the container when it is fed to the filling system, in particular is contaminated by filling material during filling, but also during feeding to the closing system or during closing. Therefore, between the filling and the closing of the container, cleaning of the mouth area of the container has hitherto been carried out, in which, for example, a flushing liquid jet is directed onto the mouth area of the container and this is then optionally dried by a blowing device or this is cleaned using a brush or a cloth, to remove the contents stored there.
- a flushing liquid jet is directed onto the mouth area of the container and this is then optionally dried by a blowing device or this is cleaned using a brush or a cloth, to remove the contents stored there.
- a disadvantage of this procedure is that drops of washing-up liquid, broken bristles of the brush or lint of the cloth can get into the interior of the container, and the contents of the container are thus contaminated.
- this procedure can result in Flushing liquid which has penetrated into the mouth region of the container dissolves the container contents in the mouth region of the container, which leads to a clumping of the container contents.
- Multi-part container closures are also known in particular.
- two-part zippers are used which consist of a sealing film stretched over the mouth region of the container and an outer closure provided with a zipper. If these closures are used to close containers according to the method just discussed, the disadvantages already described also occur here.
- a method for closing a container by means of a closure which has a closure cap and a sealing device which comprises a sealing cap.
- the mouth region of the container is cleaned between the fitting of the sealing cap and the fitting of the sealing cap.
- the closure cap and the sealing cap which are separated before the container is closed and also placed on the container in separate process steps are merged only during the closing process of the container.
- the sealing cap is fed to the container and placed on the mouth region thereof. Since the sealing cap closes the mouth region of the container, penetration of substances contaminating the container contents is reliably avoided during the cleaning of the container mouth, so the container contents cannot be affected by the cleaning process.
- a preferred embodiment provides that the mouth area of the container is cleaned by spraying, brushing and / or wiping it. It is also possible to apply a drying gas to the mouth area.
- the various cleaning options individually or in combination, ensure optimal cleaning of the mouth area.
- the closure cap is made of metal and the method comprises placing the sealing insert on the mouth area, cleaning the mouth area, placing the closure cap on the mouth area and shaping the closure cap.
- This embodiment variant represents the adaptation of the method according to the invention to a metallic closure cap. After the sealing cap has been placed on, cleaning and, if appropriate, drying, a blank closure cap is placed on the mouth region, which is machined into a finished closure cap. During molding, for example as the thread of the closure or notches incorporated, which serve the easier opening of the closure.
- a further preferred embodiment variant provides that the closure cap is designed as a screw cap and consists of plastic, and the method comprises placing the sealing insert on the mouth region, cleaning the mouth region, placing the closure cap on the mouth region and screwing the closure cap onto the mouth region ,
- This embodiment variant of the method is adapted to the screw cap made of plastic. The screw cap is thus already finished before it is placed on the mouth region of the container and screwed on.
- the sealing insert is put on by means of a first fitting tool, the mouth region is cleaned by means of a cleaning tool, preferably a rinsing nozzle and / or an automatic brush and / or a wiping device, and the mouth region is dried by means of a Drying tool, preferably a blow nozzle, the closure cap is attached by means of a second attachment tool and the shaping of the closure cap by means of a shaping tool, preferably a deep-drawing tool, in particular a plunger and thread rollers.
- a cleaning tool preferably a rinsing nozzle and / or an automatic brush and / or a wiping device
- the mouth region is dried by means of a Drying tool, preferably a blow nozzle
- the closure cap is attached by means of a second attachment tool and the shaping of the closure cap by means of a shaping tool, preferably a deep-drawing tool, in particular a plunger and thread rollers.
- all steps of the method are carried out using tools developed for this. The procedure can
- plastic closure cap designed as a screw cap
- the screw cap is also screwed onto the mouth region by means of a tool. This means that plastic screw caps can also be placed in a fully automatic filling line.
- the sealing insert is designed as a sealing cap and has at least one holding means which interacts with the container.
- the design of the sealing insert as a sealing cap requires the adaptation of its size to the mouth area of the container, that is, the dimensions of the sealing insert are selected so that after the sealing insert is placed on the mouth area of the container, the sealing insert or the sealing cap is securely held place.
- the term "sealing cap” indicates that the sealing insert already takes on properties of a sealing cap, namely the sealing.
- the holding means which cooperates in particular with the mouth region of the container, enables the sealing insert to be supported in the mouth region, that is to say that the sealing insert does not slip when pressure is applied from the inside or from the outside.
- the pressurization can be done, among other things, by cleaning in the form of spraying with the cleaning liquid or drying in the form of an action of the cleaning gas flowing out of a blowing nozzle.
- the sealing insert is held securely in the mouth area of the container with both types of loading.
- the holding means is designed as a web running around the sealing cap and extending essentially perpendicularly away from the wall of the sealing insert. This design of the holding means provides the largest possible area for the interaction of the sealing cap with the container.
- the seal cap is held in the mouth area of the container by clamping the seal cap in the mouth area. Depending on the spatial shape of the sealing cap, this clamping can take place on the inside of the mouth area and also on the outside thereof.
- an embodiment of the closure which has a latching means which is designed as a circumferential projection and is also called a bead and which can hold the sealing cap.
- the locking means enables the screw cap and the sealing cap to form a positive connection in the case of the metallic screw cap when it is being shaped and in the case of the plastic screw cap when it is screwed on. This connection is not released by a consumer even when the closure is removed, that is to say the consumer can remove the closure cap and the sealing cap from the mouth region of the container in one operation. In the event of a closing the container, the sealing cap is then already firmly integrated into the sealing cap.
- the sealing cap has a bottom, a circumferential wall starting from the bottom and a brim adjoining the wall and provided with a bent edge.
- This configuration of the sealing cap provides further surfaces which can interact with the mouth region of the container.
- the brim can rest on the top of the mouth area and the bent edge of the brim on the outside of the mouth area of the container. This configuration of the brim therefore further improves the secure hold of the sealing cap in the mouth area, as well as its sealing properties.
- a closure in which the bottom of the sealing cap has a first base area and a second base area extending at an angle therefrom.
- the bottom of the sealing cap is thus plate-like. This has the advantage that drops of the cleaning liquid, which collect on the surface of the sealing cap after cleaning, converge under the force of gravity towards the first base surface of the sealing cap and can thus be removed more easily in the event of drying.
- the base is designed as a truncated cone jacket.
- the bottom of the tion cap thus extends like a wedge into the mouth region of the container.
- the wedge shape also favors drops of cleaning fluid.
- an embodiment of a closure is preferred, which is characterized in that the metal of the closure cap is aluminum and the sealing cap is made of plastic. Furthermore, the sealing cap can consist of metal, preferably aluminum, coated with a sealing compound. The choice of these materials guarantees simple and inexpensive manufacture of the sealing cap and the sealing cap.
- Figure 1 shows the mouth area of the container when putting the sealing cap in section
- Figure 2 shows the mouth area when cleaning by means of a cleaning liquid in section
- Figure 3 shows the mouth area when placing the cap in section
- Figure 4 shows the mouth area after unscrewing the cap in section.
- FIG. 1 shows the mouth area 1 of a container 2.
- the mouth area 1 has an external thread 3 and a circumferential bead 5 arranged underneath on .
- a sealing cap 7 comprising a sealing insert is placed on the mouth region 1 of the container 2, which is indicated by arrows 9.
- the sealing cap 7 has a bottom 11, a circumferential wall 13 starting from the bottom 11 and a brim 15 adjoining the wall 13.
- the brim 15 is provided with a bent edge 17.
- the bottom 11 of the sealing cap 7 is composed of a first base area 19 and a second base area 21 extending at an angle therefrom.
- the sealing cap 7 also has, at the lower end of the circumferential wall 13, a holding means 25 designed here as a circumferential web 23.
- the holding means can also be realized by a press fit, that is to say in that the sealing cap 7 is securely held solely by its dimensions matched to the mouth area 1.
- the web 23 can also be dispensed with.
- the bottom 11 of the sealing cap 7 can also be designed in the shape of a conical shell or a truncated cone. In cross-section, it then extends approximately wedge-shaped into the mouth area 1 of the container 2.
- the first base area 19 of the base 11 of the exemplary embodiment of the sealing cap 7 shown here has a thickness of approximately 0.5 mm, for example.
- the thickness of the second base surface 21 of the base 11 is approximately 0.4 mm.
- the thickness of the sealing tion cap 7 In the area of the peripheral wall 13, the thickness of the sealing tion cap 7 about 0.3 mm.
- the brim 15 has a thickness of 0.4 mm in the region of its non-bent edge 17, while the thickness in the region of the edge 17 is approximately 0.7 mm.
- the circumferential wall 13 and the second base 21 of the base 11 enclose an angle ⁇ of approximately 110 °.
- the angle ⁇ between the first base surface 19 and the second base surface 21 of the base 11 is approximately 160 °.
- the embodiment of the sealing cap 7 of FIG. 1 clearly shows which surfaces of the sealing cap 7 cooperate with the mouth region 1 of the container 2 apart from the circumferential web 23.
- the bent edge 17 of the brim 15 interacts with an outer surface 27 of the mouth area 1, while the horizontal section of the brim 15 cooperates with an upper side 29 of the mouth area 1.
- the upper edge of the sealing cap 7 shown in Figure 1 is shown differently on the right and left. On the right side, the previously described embodiment of the sealing cap 7 can be seen. Another embodiment is shown on the left side of the sealing cap 7. This is characterized by the fact that the brim 15 merges into a wall region 30a which is angled downwards and forms a quasi-circumferential ring which is more or less cylindrical. This wall area engages over the outside of the mouth area 1 of the container 2, when the sealing cap 7 is placed on the container 2. This results in a firm hold of the sealing cap 7 on the container on the one hand, and an additional sealing surface on the other hand.
- the circumferential brim 15 of the sealing cap can also be formed without a bent edge 17 and without the wall region 30a which is angled downwards, that is to say it can be designed to run horizontally up to the outermost edge.
- the brim 15 always remains in a straight, horizontal shape, that is to say also when the container 2 is finally closed with a closure cap, which will be discussed in more detail below.
- the outermost edge region of the brim 15 can be molded on the outside of the surrounding container wall when the closure cap is put on.
- the downwardly bent edge 17 can be formed, or else the downwardly angled wall region 30a.
- the initially horizontally circumferential brim 15 is reshaped, that is to say possibly quasi deep-drawn, during the final closing process in order to form the bent edge 17 or in particular the angled wall region 30a or the circumferential ring.
- webs 30b can be provided, which extend from the circumferential wall 13 to the center line M shown in broken lines.
- the bars the number of which can be freely selected within a wide range, all converge in the area of the center line. Its width is essentially freely selectable.
- Their height can be essentially constant over the length of the webs 30b. In the exemplary embodiment shown here, it is provided that the height of the webs 30b starts from the circumferential wall 13 in the direction of the center line M.
- the arrangement of the webs 30b can be chosen such that two webs lying opposite each other lie on an imaginary diameter line of the sealing cap 7. Here it is provided that they follow an imaginary radius line. For example, six such webs are provided, which are arranged at the same distance from one another.
- the webs 30b serve on the one hand to stiffen the sealing cap 7. It can also be provided on the other hand to produce the sealing cap 7 from an oxygen-absorbing material in order to absorb the oxygen present between the closure and the content of the container 2 after it has been closed. It can thereby be achieved that the content of the container, for example beer, shows a better shelf life.
- the webs not only serve to stabilize the sealing cap 7 but also to add additional material. rial in the cap to ensure a higher oxygen absorption.
- the webs increase the oxygen-absorbing surface of the sealing cap 7
- the webs 30b described here can be provided both with a sealing cap 7, which have the embodiment shown on the right side in FIG. 1, and with sealing caps, which show the embodiment shown on the left side in FIG.
- FIG. 2 shows the sealing cap 7 completely introduced into the mouth area 1 of the container 2 during cleaning.
- the same parts are provided with the same reference numerals as in FIG. 1, so that reference can be made to the description there.
- the sealing cap 7 which thus serves as a molded seal or also as a pre-closure and in specialist circles also as a displacer is designated, the interior of the container is protected from the ingress of oxygen.
- the sealing cap 7 only closes the uppermost mouth region 1 of the container 2, the container wall is exposed undisturbed and is therefore easily accessible for a cleaning process. Leftover contents, especially sugar, can therefore be removed easily and practically without residues, so that bacteria and in particular molds cannot find a breeding ground.
- FIG. 2 shows a cleaning tool 33 comprising a rinsing nozzle 31.
- the rinsing nozzle 31 delivers a cleaning liquid 35 in the form of a jet onto the mouth area 1 of the container 2.
- the cleaning liquid 35 can thus remove residues of the contents of the container 2 located in the mouth region 1 of the container 2, in particular in the region of the external thread 3 and the circumferential bead 5, without drops of the cleaning liquid 35 being able to get into the interior of the container 2.
- the cleaning liquid 35 can be pure water, but also water with a detergent or disinfectant additive.
- FIG. 2 shows a rinsing nozzle 31 which, for example, sprays the mouth region 1 to be cleaned from above with a cleaning liquid. It is also conceivable to provide a rinsing nozzle which sprays the container from the side with cleaning liquid, in particular in the upper region near the sealing cap 7. Adhesive ingredients, in particular sugar and the like, can be removed particularly effectively in this rinsing direction.
- a drying step can be carried out, in which a drying tool having a blowing nozzle blows a drying gas onto the mouth region of the container 2, as a result of which the drops of cleaning liquid still adhering to the mouth region 1 of the container 2 or to the sealing cap 7 35 be removed from the mouth area 1.
- Air is an example of a drying gas. Drying can also be carried out in a suitable other way, for example by means of heat radiation and / or a drying agent.
- the cleaning effect of the cleaning liquid 35 as well as the drying effect of the drying gas can be increased by heating the cleaning liquid and the drying gas before application to the mouth area 1.
- FIG. 2 also clearly shows how the sealing insert 7 is supported in the mouth region 1 of the container 2 by the holding means 25, here by the web 23.
- this clamping can be reinforced by a compression extending over its entire thickness.
- sealing cap 7 An exemplary embodiment of the sealing cap 7 is not shown in the drawing, in which the bottom of the sealing cap is not located in the mouth region 1 of the container 2, but rather extends essentially above it.
- the circumferential web is arranged such that it engages on the outside of the mouth region 1 by clamping.
- the web can be replaced by an interference fit between the sealing cap and the outside.
- FIG. 3 shows the mouth area 1 of the container 2 with the sealing cap 7 therein serving as a sealing insert during the fitting of a screw cap 37, which is symbolically represented by arrows 39.
- the same parts are the same Reference numerals as in Figures 1 and 2 provided so that in this respect reference can be made to the description there.
- a holding means or internal thread 41 located in the interior of the closure cap 37, which engages with the external thread 3 of the mouth region 1 after the container has been closed.
- FIG. 3 clearly shows a guarantee band 43 which, after being closed, is adapted to the circumferential bead 5 of the mouth region 1.
- FIG. 4 shows the mouth region 1 of the container 2 with the sealing cap 7 and the sealing cap 37 after the container 2 has been sealed with the sealing cap 37.
- a latching means 47 designed as an at least partially circumferential projection 45. Circumferential areas means that the projection can be composed of a plurality of tab-shaped individual projections.
- the latching means 47 is used to produce a positive or non-positive sigen connection between the sealing cap 7 and the closure cap 37 when closing the container 2. If the container 2 is opened by a consumer, that is, the closure cap 37 designed as a screw cap is unscrewed from the mouth region 1 of the container 2, the locking means 47 occurs Cap 37 with the edge 17 of the sealing cap 7 in driving connection. The force exerted on the screw cap 37 by the consumer is thus transmitted to the sealing cap 7 via the latching means 47 and the edge 17 of the brim 15.
- this force is in any case greater than the force with which the circumferential web 23 is supported in the mouth region 1 of the container 2, it is ensured that the sealing cap 7 is preferably always removed from the mouth region 1 of the container 2 together with the closure cap 37. If the consumer closes the container 2 one more time, the closure cap 37 and the sealing cap 7 are applied or screwed together onto the mouth region 1 of the container 2. The sealing effect of the sealing cap 7 is retained even after the container 2 has been opened and closed several times.
- the state of the container 2 shown in FIG. 4 is produced in two ways, depending on whether the closure cap is made of metal or plastic.
- a closure cap made of metal a cap blank is placed on the mouth region 1 of the container 2 which does not yet have an internal thread 41.
- the transition area between the bottom and jacket of the cap blank closing the mouth of the container 2 is deep-drawn in order to press the sealing insert or the sealing cap against the container in a sealing manner.
- the jacket is then pressed onto the mouth region 1, in particular against its external thread 3, by means of at least one suitable pressure roller, as a result of which the internal thread 41 is formed.
- no blank, but already the fully formed closure cap is put on.
- the plastic cap thus already includes the internal thread, so that the cap only needs to be screwed on to close the container.
- the closure is formed in two parts and has a closure cap and a sealing cap.
- the decisive factor is the two-part design of the closure, which makes it possible to temporarily close a container after it has been filled using the sealing cap, so without Disadvantages for the contents of the container, a cleaning process can be carried out. This leads to the fact that residues of content can be removed from the mouth area of the container and that the infestation of bacteria and the like can thus be reduced or avoided entirely. After cleaning, the container is then finally closed by means of the closure cap.
- closure cap is designed as a closure cap blank, which is then formed into a screw closure in a molding process. It is also possible to place or screw a finished screw cap, in particular made of plastic, onto a container closed with a sealing cap.
- closure cap can also be designed as a crown cap which, after the provisional closure of the container and a cleaning process, is placed or pressed onto the container or the sealing cap and, if appropriate, molded onto the mouth region of the container with a suitable molding tool and thus finds a secure hold.
- crown corks can be used here, but also so-called crown rotating corks, which can be unscrewed from the container or its mouth area after the usual closing and molding process.
- crown rotating corks which can be unscrewed from the container or its mouth area after the usual closing and molding process.
- the outside of the container must of course be provided with a thread or with a reefing acting as a thread.
- caps listed here are only examples. It is of course also conceivable to combine the sealing cap 7, which acts as a pre-closure or molded seal, with differently designed closure caps, for example also with so-called twist-off closure caps. It is essential that the closure is formed at least in two parts and the sealing cap or the pre-closure initially closes the container in an airtight manner and the closure of the container is then finally effected by the closure cap, the special configuration of the closure cap then being freely selectable in this connection.
- the design of the sealing cap 7 can then be adapted to the different types of sealing caps.
- the sealing cap in the case of crown rotating corks, for example, it is conceivable that the sealing cap, as explained with reference to FIG. 1, is molded onto the outer wall region of the container 2 by the closure cap and thereby extends over a larger region of the outer wall, as is the case, for example, with reference to the bottom angled wall region 30a was explained.
- the sealing cap can be provided with a thread which then engages with an external thread of the container.
- Alien closure types have in common that the initially two-part closure can be handled as a preferred unit after the closure process. This means that the sealing cap snaps into the interior after the closure cap has been put on, because, as described for example with reference to FIG. 4, locking means 47 are provided there which hold the sealing cap securely after the closure cap has been put on.
- all types of closure described here it is therefore possible, owing to the two-part closure after filling and the provisional closure of the container, to carry out a cleaning process using the sealing cap and only then to finally clean the container using the closure cap, which, as stated, can be of any design. to close.
- the sealing cap is preferably made of plastic, whereby combination forms are also possible in which the sealing cap can consist of a basic metal form which is coated with plastic.
- the sealing cap can also consist of more than two Materials.
- the plastic ensures that the opening forces in screw closures are reduced to a usable level due to the lubricity of the plastic. This means that the opening forces can be set relatively well to small values due to the slidability, so that no problems occur when a consumer opens the container.
- oxygen-absorbing plastic or a barrier material can also be used in the choice of the material of the sealing cap, so that the durability of the filling material present in the container is increased.
- a suitable choice of the plastic for the sealing cap can ensure that the sealing effect of the closure remains essentially the same even when it is opened and closed several times, so that a high level of security can also be achieved.
- the container can be closed well to avoid spoiling the contents, on the other hand, an overpressure limitation can be ensured and maintained by special design of the sealing cap and the closure cap even if the closure is opened and closed several times.
- the described method and the illustrated closure cap can be used in both disposable and reusable containers. If the container 2 is returned to the manufacturer together with the screw cap and the sealing insert located in it, water by means of suitable tools even separate the sealing cap and the sealing insert or the sealing cap from each other. In particular, it is easily achievable to send these two parts separately to a recycling process.
- the described method enables a container to be closed in a hygienically perfect manner when the described closure is used.
- the closure comprises a closure cap and a sealing insert which is formed separately and can be handled separately, the mouth region of the container being cleaned between the attachment of the closure insert and the attachment of the closure cap.
