Definitions
- the invention relates to a device for sealing beverage packaging, in particular beverage packaging made of plastic, which are under internal pressure, according to the preamble of the independent claim.
- the closures of these packagings require very high closing forces so that sufficient tightness between the sealing surfaces is guaranteed.
- the resulting high operating forces represent a disadvantage.
- these closures have a very low fault tolerance and therefore require a very high degree of precision during manufacture. Manufacturing is therefore very expensive.
- the object of the invention disclosed here is a device for
- the Sealing device should be particularly suitable for closures with a hinge and / or a seal of approval.
- the invention consists in a sealing device for sealing an opening of a beverage packaging.
- the sealing device has a sealing means which is designed and arranged in such a way that it generates a sealing force which is proportional to the internal pressure and acts on an edge region of the opening to be sealed.
- the sealing device is designed such that the sealing effect is largely independent of a high initial force. Due to the design, dimensioning and arrangement of the sealant and the surface exposed to internal pressure, the sealing effect, respectively. -power set.
- the sealant is designed to be completely or partially flexible in comparison to the surrounding elements, in such a way that it deforms as a result of a pressure difference (internal pressure).
- the sealing effect is achieved in that the deformation of the sealant is specifically hindered, so that a sealing force arises due to the obstruction.
- Materials which can be processed by injection molding and have a Shore hardness which is preferably in the range from 20 to 80 are preferred.
- the flexibility of the sealant required for proper functioning depends on the geometry and the mechanical properties of the adjacent areas. Good experiences have been achieved with materials that have mechanical properties that are similar to those of silicone.
- the invention disclosed here is particularly suitable for one or more-part closures made of plastic.
- the sealing means can form an integral part of the closure or can be designed as a separate part. If necessary, closures are preferably manufactured using multi-component injection molding. It is thus possible, for example, to integrate a device with a flexible sealant into a comparatively less deformable closure by means of different material selection.
- the invention is explained in more detail with reference to the following figures. They show schematically and very simplified:
- Figure 1 shows a first embodiment of a sealing device
- FIG. 1 is a detailed view of Fig. 1;
- Figure 3 shows the device of Figure 1 in an open position.
- FIG. 4 shows an SG hinge closure in the closed position
- FIG. 5 shows the hinge closure according to FIG. 4 in the open position
- FIG. 6 shows a closure with a further embodiment of a sealing device
- Figure 7 shows the closure according to Figure 6 in a front view
- FIG. 8 five embodiments of sealants.
- FIG. 1 schematically shows a closure 1 with a sealing device according to the invention which serves to seal an opening 5.
- the illustration shows the closure 1 with a closure body 2 and a sealant 3 in a sectional view.
- the closure 1 is here arranged on a neck 4 of a container, the opening 5 of which it seals.
- the sealant 3 here consists of a separate element which corresponds at least in regions to the inner surfaces of the closure body 2 and is supported on the latter.
- the sealant 3 has a collar 10 which, in this illustration, is in a releasable operative connection with an edge of a neck (henceforth neck edge) 11 of the opening 5 to be closed.
- the collar 10 is designed to be flexible in comparison to the closure body 2 in such a way that it is increasingly supported on the neck edge 1 1 under internal pressure and thereby seals it.
- the collar 10 is designed in such a way that when the closure 1 is placed on the neck 4 it undergoes a certain deformation caused by the neck edge 11, which produces an initial sealing effect.
- the closure body 2 has two laterally arranged arms 6 which open into a ring 7.
- the ring 7 surrounds the neck 4 and has protruding locking elements 8 which are fastened to the ring 7 and are in engagement in the closed position with a locking edge 9 which projects radially on the neck 4.
- the closure 1 is securely closed.
- the closure 1 can be unlocked by the ring 7 being deformed by lateral pressure, in such a way that it ovalizes and releases the locking elements 8.
- the closure 1 has means for centering the closure 1 on the neck 4. These means, which are not shown in detail here, can be designed as ribs projecting radially inwards. They serve to position the collar 10 relative to the edge 11 of the opening 5 in the unloaded state.
- FIG. 2 shows the detail D from FIG. 1. A part of the closure body 2 and the sealant 3 can be seen.
- the collar 10 is operatively connected to the neck edge 11 of the opening 5.
- the forces acting due to an internal pressure are shown schematically by means of arrows P.
- the internal pressure acting on the collar 10 causes the collar to be pressed against the neck edge 1 1 with a force K such that the opening 5 is sealed.
- the size of the resulting sealing force K can be adjusted by the design of the collar 10.
- FIG. 3 shows the closure according to Figure 1 in an open position. As can be seen, the locking elements 7 are no longer in engagement with the locking edge 9, so that the closure can be pulled off freely. When the closure 1 is unlocked, the entire cross section of the opening to be sealed is immediately released, as a result of which any gas can escape from the inside of the packaging.
- FIG 4 shows a simplified hinge closure 20 made of plastic in a perspective sectional view.
- the hinge closure 20 which is shown here closed, has a lower part 21 and an upper part 22, which are connected to one another via a hinge 23 (film hinge).
- the closure 20 is preferably produced by injection molding plastic.
- the lower part 21 has an opening 5, which is sealed by a sealing means 3.
- the sealant 3 has a collar 10 which is operatively connected to a neck edge 11 of the opening 5.
- the sealing means 3 is designed in such a way that it exerts a sealing force proportional to the internal pressure on the edge 11, such that the opening is securely closed.
- the sealing means 3 is also designed as a separate means. Of course, it can also be integrated in the hinge closure 20 or form part of it.
- the upper part 22 has a hammer-shaped locking element 25 protruding from an edge, which in the welding position engages with a corresponding nut element 26 of the lower part 21 and closes the hinge closure.
- the locking element 25 and the groove element 26 are designed such that they can be removed in an injection mold without additional means such as slides, etc.
- the closure 20 can be opened by bending the locking element 25 forward relative to the groove element 26, away from the lower part.
- FIG. 5 shows the closure 20 according to FIG. 4 in the open position.
- the film hinge 23 can be seen which connects the lower part 21 to the upper part 22 in an articulated manner. det.
- the sealant 3 can be seen inside the upper part 22.
- the sealant 3 is arranged in a casing 29 which holds the sealant and limits its lateral expansion.
- the collar 10 of the sealing means 3 consists of a relatively elastic material, in such a way that the collar 10 can be deformed without great effort.
- the hammer-shaped locking element 25 stands freely upwards from the edge of the upper closure part 22.
- the wall thickness corresponds approximately to that of the upper part 22.
- the blocking element 25 has a wider area 27 and a narrower area 28.
- the narrower area 28 is arranged between the wider area 27 and the upper part 22.
- the groove element 26, which is located at the front on the lower part 21, is designed such that it can be brought into engagement with the locking element 25.
- the locking element 25 advantageously engages in the groove element 26 from the outside. This makes it possible, for example, to achieve a guarantee by attaching a film which is placed around the closure 20 after it has been closed and which has to be removed before the first opening. The film is placed around the closure 20, the blocking element 25 and the groove element 26 such that the engagement between the blocking element 25 and the groove element 26 can no longer be released without the film being removed.
- the closure 20 is preferably screwed or bounced onto a container to be closed.
- FIG. 6 shows a sectional view of a closure 40 with a sealing device 30 according to the invention.
- the sealing device 30 is part of a sealing cap 31 and corresponds to a neck edge 11 of an opening 5.
- the collar 10 of the sealing device 30 is here at an internal angle ⁇ with respect to the Cap 31, respectively the edge 1 1, arranged.
- the collar 1 1 consists of material which is flexible in comparison with the surroundings and which is easily deformable.
- the sealing device with the collar 11 is part of the sealing cap 31 or is produced as a separate element and subsequently inserted into the sealing cap 31.
- the angle ⁇ is determined according to the requirements for the sealing effect to be achieved Internal pressure, the desired initial sealing force and the manufacturability.
- the inner contour of the collar 11 is preferably chosen so that the collar can be easily removed from the mold during manufacture by injection molding. Depending on the field of application, the inner surface can be cylindrical as long as the required elasticity of the collar 1 1 remains guaranteed.
- the outer angle ⁇ '(cf. FIG. 8) is selected such that the collar 11 can be inserted easily into the opening 5 and undergoes a radial deformation when it is placed on the neck edge 10, which builds up a ring tension. By utilizing these ring tensions, it is possible to generate a sufficient initial force acting on the edge even with very elastic material, so that a sufficient initial seal results.
- the flexibility of the collar 11 compensates for inaccuracies in the seal. In contrast to the closures known from the prior art, the invention seals even with greater inaccuracies.
- the neck edge 11 is here part of a closure seal 32 with an internal thread 33.
- the lower closure part can be screwed onto a conventional PET bottle.
- the lower closure part 32 can also be designed as part of a beverage packaging.
- the lower closure part 32 has two lateral, diametrically opposite lower closing means 34 which project radially in some areas and each have a recess 35 widening downwards.
- correspondingly designed upper closure means 36 engage in these recesses 35 and are formed on the closure cap 31 via a web 38.
- the upper closing means 36 has a widening 39 at the end of the web 38, which engages positively in the recess 35.
- the closing means 34, 36 are designed in such a way that they can be produced in an injection molding tool without a slide.
- the inner edge of the recesses 35 directed away from the closure cap 31 has an undercut.
- the widening 39 of the upper closing means 36 engages in this undercut and thereby secures the closure cap 31 against unintentional unlocking.
- FIG. 7 shows the closure 40 from FIG. 6 in a frontal view.
- the geometry of the closure 40 is selected such that when the closure cap 31 is placed on the lower closure part 32, the collar 11 is deformed slightly inwards in the direction of arrow A by the operative connection with the neck edge 11.
- the elastic material of the collar 10 resists this deformation, which results in a pressure on the neck edge 11. This pressure causes an initial sealing effect.
- the collar 10 is designed in such a way that it directs the forces in a targeted manner into the interaction area between the collar 10 and the neck edge 1 1, thus producing a sealing force which increases proportionally with increasing internal pressure.
- the collar 10 can be designed in such a way that when a defined maximum pressure is reached with the closure cap 31 closed, it specifically slips off the neck edge 1 1 and turns inside out, so that the supercritical internal pressure is reduced. This prevents the lock from jumping off dangerously.
- the initial sealing effect can be influenced by measures which influence the position of the collar 10 in relation to the neck edge 11. These measures include: varying the thickness of the bottom of the closure cap 31; Length of webs 38; Material accumulation in the area of the corresponding areas of the lower and upper closing means 35, 36. This makes it possible to set the initial sealing effect in a targeted manner by simple measures. Shrinkage problems in the hardening of plastics during manufacture can be specifically compensated for.
- the closure cap 31 has gas outlet areas 40, which bring about a targeted gas discharge when opened.
- FIG. 8 shows five different embodiments (a to c) of sealing means 30 in a perspective sectional view.
- a first sealant 30 Collar 10 arranged radially inwards. This first sealant essentially corresponds to the sealant 3 from FIGS. 1 to 5.
- the second sealant 30 (b) has an inwardly extending collar 10.
- the collar 10 has a constant wall thickness and is supported by ribs 41 arranged on the outside. This embodiment is suitable for very high internal pressures. The area in which a neck edge rests is indicated by a dashed line 42.
- the third sealant 30 (c) essentially corresponds to the sealant from FIGS. 7 and 8. This third sealant 30 also has an inwardly inclined collar 10.
- the collar 10 has a wall thickness that decreases towards the edge. The pressure surface 45 of the collar 10 exposed to the internal pressure is shown hatched.
- the fourth sealant 30 (d) essentially corresponds to the third sealant (c).
- This fourth sealing means has in the sealing area 42 on which it rests on a neck edge projecting annular means which bring about a concentration of the sealing forces.
- the fifth sealant 30 has a collar 10 which has an inward bend.
- the shape of the collar causes an additional concentration of the sealing forces in the sealing area 42.
- the sealing means a to e shown are particularly suitable for hinge locks.
