Definitions

  • the invention relates to a closure unit (container and closure lid), a closure (also: closure lid) and a method for a container (also: vessel) made of glass or plastic, consisting of a container with a container neck with external threaded elements, the closure lid being provided with an axial Pressing is applied to the container neck and is released from it by a screwing process. More precisely, it is a press-on / twist-off closure.
  • the preferred form of the closure cover comprises a shell body made of metal with an upper mirror (panel) and an apron section projecting axially (downwards) therefrom.
  • the generally cylindrical upper section of the skirts has a deformable plastic lining into which threads are formed when it is pressed vertically onto a mouth which is equipped with thread segments radially on the outside. The consumer can later remove the closure cap from the container body by means of a normal loosening movement, see U.S.
  • the person skilled in the art achieves a hermetic sealing of containers for packaging and for preserving food, in particular baby food.
  • the food can be filled hot (above 70 ° C) and after sealing and cooling, a vacuum is created that can make it more difficult for the consumer to unscrew the lid (the "opening value" as the torque to be used).
  • the invention has set itself the task of reducing the metal, glass and plastic consumption in the production of the closure lid, the closed closure unit (container and lid) and the associated processes without sacrificing quality and consumer benefits.
  • closure cover made of sheet metal (claim 10). It is suitable for a plastic or glass container and is also designed and adapted mechanically for this purpose (claim 1).
  • the glass container has external, circumferentially offset threaded elements that replace a continuous thread, but are staggered on the circumference. These threaded elements are arranged on a container neck of the container body to which the closure lid (also "metallic" closure lid) is to be assigned.
  • the closure cap is to be pressed axially onto the container neck and over the threaded elements.
  • the closure lid is adapted and designed, with the closure lid having a plastic layer which, on the inside of the lid, rests against a circumferential transition zone and against the apron section, namely in a permanently adhesive manner.
  • This plastic layer has an axial extension and a radial extension.
  • the mentioned transition zone is oriented circumferentially, connects the central area of the closure lid (usually called a "panel") with the axially protruding apron section.
  • the latter leads over into a curling area, which can have an inner curl or an outer curl.
  • This axial force transmitted to the compound via threaded elements is adapted very precisely and must be coordinated; if this force is too small, the cover remains down and cannot be unscrewed in the axial direction (due to the rotary movement). If the adhesion of the compound to the threaded elements is too weak, holding it for sealing during transport, in storage condition and during the duration of a sales offer on the shelf and also in the event of temperature fluctuations is not sufficient. If the force is too great, the closure will not be easy to open. The vacuum in the container must also be taken into account and influences the forces mentioned.
  • the claimed closure unit (claim 1) consists of a glass container with external, circumferentially offset threaded elements on a container neck of the glass container.
  • a sealing cover made of sheet metal is also provided, the sealing cover having a circumferential plastic layer on the inside of the cover, which is arranged on it in a sealing and holding manner and also acts.
  • the closure cap is (or: was) pressed onto the container neck and can be opened with a rotary movement via the threaded elements and a vertical section of the plastic layer. That describes its technical / structural design. So also for the container neck of the jointly claimed glass container (claim 1).
  • the stressed state is the closed state after the closure lid has been pressed onto the container neck.
  • the container neck has a horizontally oriented "surface" (as the upwardly facing end face) on which a horizontal section of the plastic layer on the closure lid rests in a sealing manner under pressure.
  • the closure cover has a central area, an adjoining, circumferentially oriented transition zone and an axially protruding skirt section which leads into a curling area.
  • the plastic layer is arranged on the inside of the lid, adhering to the transition zone and the apron section.
  • An axial extension of the skirt section and a radial dimension of the horizontally aligned end face of the container neck form a first ratio, called v 1 , which is less than 3.00.
  • the separately claimed cover (claim 10) also achieves this combination task in that it implements a ratio of two functional elements which is defined as follows: an axial extension of the skirt section and a radial extension of the transition zone form a (second) ratio , called v 2 , which is less than 1.00.
  • v 2 a ratio of two functional elements which is defined as follows: an axial extension of the skirt section and a radial extension of the transition zone form a (second) ratio , called v 2 , which is less than 1.00.
  • the radially aligned section of the plastic layer presses in the same way, functionally accurate and reliable on the upper end face of a mouth area of the container.
  • This opening area, or the upper end face presses itself a little way into the plastic layer after the closure cover has been pressed on, so that not only pure contact but also sealing under pressure is given.
  • the claimed ratio says that the radial extension of the transition zone, which is responsible for the axial sealing, is greater than the axial length of the skirt section.
  • the skirt section means a straight, cylindrical section of the closure lid which can have a curl at its lower end. This can be an inner curl or an outer curl that adjoins the apron section; directly afterwards with the outside roll, or with the interposition of a widening transition section with the inside roll.
  • transition zone which gets its name from the transition between the panel (cover surface) and the axial skirt (skirt section), also has curved elements.
  • a radially outer end section of the transition area is accordingly a 90 ° bend in order to merge it into the continuously straight skirt section.
  • an inner curling area is arranged at the lower end of the apron section, which runs in a straight line and has no mechanical beads or threaded elements, there is a transition area between this inwardly reaching curling area (directed radially inward) and the lower end of the straight apron section.
  • This transition area widens in the radial direction so that the subsequent, inwardly directed curl has a sufficient space outside the container wall (the lower end of the mouth area) formed by spacing.
  • the curling area (outer roller or inner roller) has at least a 360 ° curl, in a preferred embodiment.
  • an arch is preferably provided in the outer curvature area of the transition zone of the closure lid so that the preferably straight, axially protruding skirt section extends between said arch and the curl.
  • curling does not mean that it is an inwardly directed curl, but rather an outwardly directed curl is also claimed with this terminology.
  • the said ratio of the axial extent of the skirt section and the radial extent of the transition zone is greater than 0.85 and thus less than 1.0.
  • the outer curling and the inner curling "playing a role" based on particularly preferred ranges of the second ratio.
  • the ratio is preferably 0.9 with a range of ⁇ 5% deviation, in particular 0.89 with a more precisely specified second ratio of 0.89 with a deviation range or a tolerance band of ⁇ 1%.
  • a container is provided with an end section which has at least two, but preferably many, thread segments extending circumferentially (and inclined) thereon. Due to their large number, these inclined thread segments are nested with respect to one another or arranged in a staggered manner on the circumference of the container mouth facing outwards.
  • the closure cover is pressed open axially, that is to say pressed over the thread segments in the axial direction by a pressing force, the thread segments being pressed into the elastic plastic layer due to their rigidity. This ensures that, when it is subsequently loosened, the segments in the embossed tracks lift the closure cover axially upwards when it is rotated. As long as this torque does not occur, the pressed-on closure lid remains placed on the end section of the container (the mouth area) in such a way that the axial section of the plastic layer arranged on the cover side at the transition zone and the skirt section comes into axially locking contact with the threaded segments of the container.
  • the thread segments are guided around the circumference in order to lift the sheet metal cover axially and detach it from the thread segments, with the result that the container comprising the closure cover and container is opened.
  • Claim 19 comprises a comparable closing method in which the glass container is also closed and has an end section with many thread segments extending thereon with a circumferential offset.
  • the closure lid is designed in such a way that it has the circumscribed skirt section and the circumscribed transition zone.
  • the radially directed transition zone forms the standard of comparison, the axially extending skirt section being adapted in the order of magnitude to the extent of the radially directed extent (or: the radial extent of the transition zone).
  • This claimed order of magnitude encompasses a range of the ratio between 0.8 and 1.1, so it is not the "physical order of magnitude", but analogously a size adjustment that differs significantly from the prior art because the axial skirt section is significantly different in the prior art represents much longer or larger than the radially extending transition zone.
  • the axial distance that can be defined in this way has a dimension that is less than 2.0 mm or even less. This stands for an axial section of the container neck that is significantly shortened compared to the prior art, with no threaded elements being provided on this section. The threaded elements are arranged on a section axially further down so that they are not omitted.
  • the radially outer end section of the transition area can have a 90 ° curve. It goes directly into the straight apron section.
  • the axially straight skirt section is perpendicular to the plane in which the central area of the closure cover lies.
  • curling at the lower edge of the apron section there are two variants for curling at the lower edge of the apron section, outer curling and inner curling.
  • a “curl” should be understood to mean an essentially circular configuration. If this circular formation is an outer curl, it connects directly to the straight apron section. If the curl is an inner curl, there is a transition area between the straight apron section and the inner curl which causes the radial dimension of the apron to expand. With this internal curling, the first ratio is preferably designed so that it is below 2.70.
  • a metallic apron protrudes from this at the bottom, the plate together with the apron circumscribing and delimiting a generally cylindrical inner recess.
  • the metallic apron runs continuously in a straight line until it ends in a curled section.
  • the axial shortness of the apron is also circumscribed by a ratio in this closure cover.
  • An axial length of the metallic apron is smaller than a radial extension of a transition zone between the upper end of the metallic apron and a radially outer end of the metallic one Plate.
  • this transition zone does not have to be straight and radial, but rather the sheet metal in this transition zone can circumscribe a trough which can have several radii of curvature and one or more inclined sections.
  • the transition zone acts like a kind of channel to accommodate a radial section of a compound.
  • the axial section of this compound extends on the inside of the cylindrically shaped skirt and, in addition to a sealing function, also forms the holding function and screwing function of the PT concept.
  • the compound is preferably a PVC compound or a TPE compound.
  • the curl can be directed outwards or inwards, adjoining the metallic skirt;
  • the metallic apron is bell-shaped in the lower end area, there are three sections, a cylindrical section, the widening, bell-shaped section and then the inner curl. This is different with the outer curling, which is arranged directly at the lower end of the cylindrical section of the apron without an intermediate section being temporarily stored.
  • the method of closing the container assembly includes steps that involve the design of the closure lid.
  • the container is provided and has an end portion with at least two, preferably several, thread segments extending circumferentially thereon. These thread segments can be arranged circumferentially staggered, preferably not more than two staggered thread segments are arranged one below the other in the axial direction, usually so when a first thread segment ends with an axially upper end, the next but one thread segment begins afterwards or shortly thereafter, below which further circumferentially and inclined middle thread segment.

  • this sectional view can stand for any circumferentially further offset axial section, with the exception of the height position of the two illustrated thread segments 54, 55, which depending on the circumferential rotation of the vertical section in a different height position of the outer Surface of the container neck 52 lie.
  • the attached closure cap 2 is also shown in the cutout, primarily in its holding area at the mouth 52.
  • the dimension D i is the radial diameter dimension of the cover surface 11, which can also be referred to as the central area. It extends radially within a circumferential kink 11a ', which merges into the edge area, which is represented by the reference numerals 11a, 11b and 11c.
  • the external dimension D a should be described beforehand. It is the diameter of the skirt 12 which adjoins the transition zone 11a, 11b and 11c radially on the outside, but protruding downwards in the axial direction.
  • the dimension dr comprises, starting from the circumferential kink 11a ', the first ramp section 11a, a slightly less inclined second ramp section 11b above the end face 52a of the neck 52 of the container 50, and the right outer end of this second ramp section 11b merges into a curved section 11c the skirt section 12.
  • the top of the skirt portion 12 is 12a in Figure 1 , and 12b is the lower end. Between these two ends or end points, the skirt 12 runs in a straight line in the axial direction and forms a cylinder, viewed in the circumferential direction.

  • the associated reference symbols are also the same.
  • the lower axial end of the cylindrical skirt section 12 does not lead directly into a curl, but into a widening section 21a. Its upper end 21a ′ starts at the lower end of the cylindrical section 12.

  • Another dimension is the radial dimension dr in relation to the circumscribed axial height h 0 of the skirt section 12.
  • these two dimensions are of the same order of magnitude, or the height dimension is smaller than the radial dimension.
  • the radial extension is decisive for the sealing effect on the face of the mouth.
  • the axial dimension is decisive for the opening mechanism.
  • This radial dimension can be the radial dimension dr of the sheet metal cover, which consists of the three sections 11a, 11b and 11c in the transition zone, or it can be the above-described radial dimension 52a on the glass, which makes the initial sealing contact and the plane E 52a defined.
  • the latter is on the container, the former is on the lid.
  • This ratio v 2 0.98 for identifying an axially very short apron 12 can have a draw-in area of ⁇ 2%.
  • the corresponding dimensioning and definition of the assignment can also take place with a view to the radial dimension b 52 .
  • This relatively narrow dimension is supplemented by the in Figure 3 circumscribed further dimensions, which describe the effective sealing surface, so that the radial dimension of the effective sealing surface is given by b 52 *, which is 2.35 mm. Within this dimension b 52 *, the pure radial dimension of the end face 52a measures only 1.5 mm.
  • the ratio v 1 from the axial height to the pure radial dimension b 52 is calculated in the example of FIG Figure 1 with the outside role from the above values to 2.94 and is less than 3.00.
  • the comparable ratio for the inside role according to Figure 2 is that of the height dimension h 0 to the extent b 52 of the end face 52a.
  • the dimension b 52 is equal to that of the example of Figures 1 and 1 , 5 mm.
  • a relatively short apron section 12 can also be circumscribed by ratio specifications, once via the first ratio v 1 and once via the second ratio v 2 , or in a combination thereof.
  • the first ratio v 1 describes the ratio to the end face 52a on the glass vessel
  • the second ratio v 2 describes the ratio to the radial extension dr of the transition zone 11a, 11b and 11c on the closure lid alone.
  • the axial section h 0 for the closure cap is shorter than the radial dimension dr, with the height h 0 for the in the example Figure 2 is to be specified as 4.005 mm and the radial extension dr as 4.48 mm, as in the example of Figure 1 .
  • This ratio can be specified in a larger tolerance range (catchment area) of 0.9 ⁇ 5% as well as over 0.89 ⁇ 1%, shown using the example of a 59 mm sealing cap in Figure 2 , which diameter dimension D a does not play an essential role for the circumscribed ratio, since this ratio in the mouth area of the closed container 50 remains practically the same regardless of the diameter of different closures.
  • An upper limit can be named, which means that this second ratio v 2 is less than 1, but a lower limit can also be named that the ratio should be greater than 0.85, which in the case of a technical- functional limitation should always be circumscribed by an upper and a lower limit, the upper limit is decisive for the distinction from the prior art, since it is able to describe the small extent of the axial extent of the apron 12 in the best possible way.
  • the ratio v 1 from the axial height to the pure radial dimension b 52 is in the example Figure 1 with an outer roll that is 2.94 and is less than 3.00.
  • the other ratio for the inside role after Figure 2 is that of the height dimension h 0 to the extent b 52 of the end face 52a.
  • the dimension b 52 is equal to that of the example of Figures 1 and 1 , 5 mm.
  • the radial dimension of the effective sealing surface b 52 * is also given here - which has remained the same - as 2.35 mm. This can be seen because both glasses 50 are assumed to be the same, once closed with a closure lid 2 with an outer roller 22 and once closed with a closure lid 1 with an inner roller 21, each at the lower end of the apron section 12.
  • the total height of the edge area of the closure cover 2 results here as h 2 .
  • the three components are correspondingly, the axial dimension h 0 of the skirt 12, the diameter d 21 of the inner roller 21 and the axial height dimension h 'of the transition zone 11a, 11b and 11c, the Figure 1 can be taken over.
  • Dimension h 21 is the axial height of the bell-shaped widened intermediate section 21a with its lower end 21a ′′.
