Definitions

  • the invention relates to a manageable container made of glass or hard plastic with a container neck with external threaded elements, wherein a closure cap is applied by an axial pressing on the container neck (taken from the container) and is released by a screwing of him. More specifically, it is a press-on / twist-off closure unit (press-on, PT-twist-off) in special connection with a glass container or glass jar and a method for closing this container.
  • press-on / twist-off closure unit press-on, PT-twist-off
  • closures provide hermetic sealing of containers for packaging and preserving food, especially baby food or sports nutrition.
  • the food can be filled hot and after closing and cooling creates a vacuum that can significantly complicate the Loscardzi the cap by the consumer.
  • the preferred form of the closure lid comprises a metal shell body having an upper mirror (panel) and a skirt portion projecting axially thereof (downwardly).
  • the generally cylindrical upper portion of the skirt portion has a deformable plastic liner into which threads are formed when pressed vertically onto an orifice equipped radially with thread segments. The consumer can later remove the cap from the container body by a usual loose twisting movement, cf. U.S.
  • the invention has set itself the task of reducing the consumption of metal, glass and plastic in the creation of the container, the closed or closable closure unit (container and lid) and associated methods, without suffering quality, safety and consumer benefits to let.
  • a closure unit (claim 1). It consists of a container (glass or hard plastic) with external, circumferentially offset and staggered arranged (inclined) threaded elements (also called “threads” or “thread segments”) on a container neck of the container. Belonging to a closure lid made of sheet metal is provided, wherein the closure lid lid inside has a circumferential plastic layer, which is arranged sealingly and holding him and also acts. The closure cap is (or was) pressed onto the container neck and is to be opened via the thread segments and a vertical section of the plastic layer with a rotary movement. This circumscribes its technical / structural design as well as that of the container neck of the claimed glass container.
  • the claimed state is not only the closed state (claim 37) after the closure cap has been pressed onto the container neck, but also the two "parts" which are intended for each other, but still separate from each other (claim 1). Contents are in the closed state (claim 37) contained in the container and is closed by the metallic closure lid vacuum-tight.
  • the closure lid is suitable for a plastic or glass container and also mechanically designed and adapted for the closure unit (claim 1).
  • the glass container has external, circumferentially offset threaded elements which can replace a continuous thread but can be staggered circumferentially. These thread segments are arranged on a container neck of the container body, to which the closure lid (also called "metallic" closure lid) can be assigned.
  • the assignment is done in the context of the PT concept, in which the lid is first pressed axially, and by the user, as a customer (or Consumers) is removed by a rotary motion. This is expressed by feature (a) in claim 1.
  • the closing takes place at the bottler, who reaches the seal between face and plastic layer after filling by pressing.
  • the end face presses into the horizontal section of the plastic layer a considerable distance.
  • the short mouth (a shortened neck) of the container for the closure cap contributes particularly to the solution (claim 13, 17, 31, 35).
  • the above object is also achieved with a method for closing (claim 24, 25).
  • the shortened container mouth contributes to the saving of material in particular and still achieves the required vacuum-lock security in conjunction with the satisfactory manner of opening the cap.
  • elastic PVC-backed or PVC-free elastomers or TPE thermoplastic elastomers
  • TPE thermoplastic elastomers
  • They are suitable for a cold filling at a few degrees Celsius above zero (below 10 ° C), a filling at room or normal temperature (around 20 ° C to 25 ° C), for a filling with a subsequent pasteurization (up to approx 110 ° C) or a filling with a subsequent sterilization (up to 125 ° C) of the filled product.
  • Some modern compounds as a plastic layer can cover all mentioned temperature ranges, so they are suitable for all variants of thermal filling or thermal treatment. However, it is still possible to favor certain compounds for certain temperature ranges and to use the different variants mentioned at the beginning of this paragraph.
  • the claimed closure unit consisting of container and metallic closure lid (claim 1) or the container itself (made of glass or hard plastic) are filled at the customer and then sealed (claim 24, 25) , 31, 35) at the customer so fillable and to close in accordance with a method (claim 25.)
  • the sealed state describes claim 37 to (still open) state of the closure unit (claim 1)
  • the customer will set his filling conditions so that they are suitable for the contents to be filled and give it the necessary properties on both the transport route, as well as for the period that has to wait for this bottled container on the shelf on the buyer.
  • the different filling conditions or variants lead to different results of the product performance. For example, significantly higher forces act on the compound during sterilization with compensation pressure (the plastic layer), which can lead to intersections and thus to vacuum losses and, consequently, later spoilage of the filled product (product). Furthermore, the different conditions also lead to deviations in the behavior of the opening force, which is perceived by the consumer directly when unscrewing the PT cap of the sealed container.
  • ColdFill Cold filling
  • hot fill hot fill
  • the thermal aftertreatment can take place in the form of a pasteurization or a sterilization, wherein the sterilization with a temperature of above 110 ° C acts on the filled product, currently at most 125 ° C. Below 110 ° C, to about 98 ° C the temperature of the aftertreatment, the expert speaks of a pasteurization.
  • Pasteurization pasteurization
  • sterilization can be done with or without back pressure.
  • back pressure during pasteurization is somewhat lower, for example less than 0.15 MPa, and significantly higher at sterilization up to 0.25 MPa.
  • the duration of exposure to the temperature during the aftertreatment is between 15 minutes and 60 minutes, during which the product is exposed to the higher temperature and pressure during sterilization.
  • closure unit primarily the compound (the plastic layer), which is subject to high thermal stress and is also subjected to pressure during the pasteurization or sterilization by the building up internal pressure in the closed container (with pressure to the outside, which is intercepted by a back pressure can be and / or of the thread segments, which are claimed on the loaded by a lifting force compound in the cap on "shear").
  • a vacuum forms during the cooling phase, which loads the closure and especially the compound with an oppositely directed pressure than during the thermal treatment.
  • Closure lid and primarily the plastic layer must be able to absorb both the build-up overpressure, as well as the existing after cooling negative pressure and still close tight, as well as to remain permanently tight.
  • the filling material is filled with an initial temperature which is below or at most of the order of magnitude of the temperature with which the thermal aftertreatment takes place.
  • the "post-treatment" without pasteurization or sterilization no warming temperature influence takes place.
  • the warm to hot (preheated) product with a coldfill temperature of up to 70 ° C and a hotfill temperature of up to 98 ° C is passively cooled only after filling, in the sense of "cooling down". The period of this cooling is the longer, the higher the filling temperature of the medium has been.
  • the thermal aspect of the aftertreatment can be classified into four categories, no such aftertreatment, the aftertreatment consists only of the (passive) cooling of the filled product, the post-treatment is a pasteurization or the aftertreatment is a sterilization (with a technically controlled cooling following , in the last two categories).
  • controlled cooling also takes place to cool the sealed containers to a transport temperature and to obtain the desired differential pressure on the PT lid in the cooling phase.
  • the final temperature is often the room temperature. Those products that are filled cold or at room temperature do not need to be cooled down.
  • a saving in the raw material is favored by the axially relatively short skirt of the closure cap.
  • a savings in the raw material sheet metal is achieved by the axially shortened skirt, which is in the range of the largest radial dimension, so makes in terms of area with the square of the radius in the savings noticeable.
  • the saving of the raw material plastic follows the axially shorter apron, which must be lined inside on a shorter length.
  • the closure cap must be pressed axially onto the container neck and over the threaded elements.
  • the closure lid has a plastic layer which rests on the lid inside a peripheral transition zone and on the apron section, and permanently adhesive. This plastic layer has an axial extent and a radial extent.
  • the said transition zone is oriented circumferentially, connecting the central region of the closure lid (usually called “panel") with the axially projecting apron section.
  • the latter leads into a curl area which may have an interior curl or an outside curl.
  • This axial force transmitted to the compound by means of threaded elements is adjusted very precisely and must be coordinated; if this force is too small, the lid remains down and can not be unscrewed in the axial direction (by the rotational movement). If the adhesion of the compound to the threaded elements is too weak, holding is not sufficient for sealing during transport, in the storage condition and for the duration of an offer to sell on the shelf and also in the event of temperature fluctuations. If the force is too great, the closure is not easy to open.
  • the vacuum in the container has to be considered additionally and influences the mentioned forces.
  • the container neck has a horizontally oriented "surface" (as the upwardly facing end face) on which a horizontal portion of the plastic layer on the closure lid under pressure sealingly can (claim 1, claim 13, claim 17) and in the closed state so deep depresses in that sealing is effected by pressure and impressions (claim 37, claim 25, feature (d)).
  • the closure lid has a central region with a subsequent, circumferentially oriented transition zone and an axially protruding apron portion, which leads into a Einrollungs Symposium.
  • the plastic layer is arranged inside the lid on the transition zone and the apron section adhering.
  • the closure cap as a part of the closure unit achieves this combination task by implementing a ratio of two functional elements, which is defined as follows: An axial extent of the skirt portion and a radial extent of the transition zone form a first ratio, called vi, which is less than 3.00. It is significantly smaller than in the prior art.
  • vi first ratio
  • sufficient lifting force can arise when turning, which is formed as an axially directed decrease force as a result of turning, and the power to rotate, so initially the breakaway torque is not too large and accessible or applicable for the elderly.
  • the upper end face of the mouth region of the container presses accurately and reliably in the radially aligned portion of the plastic layer.
  • This mouth region respectively the upper end face presses even a little way into the plastic layer after pressing the closure lid, forms here a sufficient three-dimensional sealing surface (as an annular surface), so that not only a pure touch, but also a clearly acting in depth conclusion is given under pressure (claim 17, last feature), based on the horizontal portion of the plastic layer of the closure cap.
  • the container neck has the overhead horizontal end surface, which is formed as an annular surface with a ring width. It is adapted and adapted to press in a horizontal portion of the plastic layer of the closure lid under pressure and seal under pressure.
  • a (third) ratio is defined in a first solution (claim 13).
  • This ratio of the axial distance to the ring width is less than 1.35 in this solution.
  • the axial distance (indicative of h 54 ) is defined as extending between the axially upper ends of the circumferentially offset threaded members and a horizontal plane through the horizontally oriented end face of the container neck of the container.
  • the ring width is defined by the overhead horizontal end face as an annular surface. It is a component of the three-dimensional acting sealing surface.
  • a distance measure of its structural structure For the container (made of glass or hard plastic) in a further solution (claim 31) is called a distance measure of its structural structure.
  • the container neck has the outside step.
  • the outboard step is placed axially above upper ends of the thread segments and below the horizontal end face so that the step is no further axially from the upper horizontal face than 1 mm. This gives the step the aptitude and property to press-seal into the horizontal section of the plastic layer (on the lid) under pressure.
  • a (fourth) structural relationship is defined in yet another solution (claim 35).
  • the container neck has the outer step, which is placed axially above upper ends of the thread segments and below the horizontal end face.
  • the fourth relationship applies. It is formed of an axial distance (illustratively: h 60 ) between the outboard step and the horizontal horizontal face and a radial width (illustratively: b 52 ) of the overhead horizontal face as the annular face and this relationship (h 60 / b 52) ) is less than 0.7, preferably even smaller (claim 36).
  • the goal achieved with this shortening of the neck or the purpose associated therewith is a double reduction of material needed. It can be achieved with the same sealing effect, that the thread segments get closer to the sealing profile, so that glass is saved; if a hard plastic is used instead of glass, the same is saved. Parallel or hand in hand is also the savings on the cover page.
  • the apron of the lid can be made shorter, as it is less far axially down to the mouth of the container to reach and cover the thread segments.
  • the maintenance of the sealing surface contributes to the fact that the material components which have been eliminated in the axial direction do not have to be added in the radial direction in order to additionally supplement the axial sealing action which is eliminated there. Instead, the radial dimension of the sealing surface should remain as known in the art.
  • the container around this sealing surface is, however, otherwise organized in terms of a sheet metal savings in the lid and other savings at or in the mouth region of the container.
  • a method by which a container assembly can be closed comprises the steps of claim 24 or 25.
  • the proximity can be specified further (claims 27 to 30). With the radial width of the horizontal end face, the length measure of proximity is specified so that no relative terms remain. It is an in-tank comparison that can be easily measured on any container. After the horizontal end face is as narrow as possible (for sufficient sealing effect), the new neck geometry is as short as possible.
  • a quotient forms the ratio (claim 26). This expresses that the axial skirt portion is short or shortened. This is related to Radial extent of the transition zone of the lid, in which zone the horizontal portion of the sealant is placed. In the examples, ratios are found for different cover diameters between 4 cm and 7 cm, which are located in the range between 1.1 and 0.8 (claim 26).
  • An axial distance and the ring width of the horizontal end face of the neck can form a further characterizing relationship (claim 27).
  • the ring width is responsible for the seal, the axial length of the distance of the axially upper ends of the thread segments of this horizontal end face defines the shortness of the neck, so that these two dimensions and their ratio is a characteristic of a shortened neck geometry with sufficient tightness (claim 27 ).
  • the container neck is preferably able to press into the horizontal section of the sealing plastic layer up to this step (claim 28).
  • outboard steps were axially so far away from the three-dimensional sealing surface that they were unable to engage the horizontal portion of the plastic layer in the closure cap.
  • the proximity of the thread segments (claim 29, claim 30) respectively their upper ends and their proximity to the horizontal end face are another means of characterizing, rewriting or putting into brevity the neckline of the neck which is more precise and definite, as the indication of the "short closure neck".
  • a horizontal dimension based on a vertical dimension, or the vertical dimension, which is "short” compared with the horizontal dimension is provided with a pull-in or uncertainty range (also: tolerance range), which includes ⁇ 10%.
  • the also claimed second ratio on the closure lid (claim 9) says as cover-internal relationship also that the responsible for the axial sealing radial extent of the transition zone is greater than the axial length of the skirt portion.
  • the skirt portion is meant a rectilinear, cylindrical portion of the closure lid which may have a curl at its lower end. This may be a réelleeinrollung or a participateinrollung (claim 8), which adjoins the skirt portion; directly afterwards with the external rolling or with interposition of a widening transition section in the inner rolling.
  • transition zone which gets its name from the transition between the panel (cover mirror) and the axial apron (apron section), also has arcuate elements.
  • a radially outer end portion of the transition region is therefore a 90 ° -bending arc to pass the lid mirror in the continuous straight apron portion (claim 2).
  • an inner curl portion is disposed, there is a transition region between this inward curl portion (radially inward) and the lower end of the straight skirt portion.
  • This transition region causes a widening in the radial direction (claim 4), so that the subsequent, inwardly directed Rolling a formed by spacing, sufficient space outside the container wall (the lower end of the mouth region) receives.
  • the Einrollungs Club (outer roller or inner roller) has a complete roll, in a preferred embodiment (claim 5).
  • a bow is preferably provided, so that the preferably straight (claim 6) axially projecting apron portion between said arc and the rolling extends (claim 2).
  • curl or shorter “curl” does not imply that it is an inwardly directed curl, but with this terminology an outward curl is also claimed (claim 8).
  • said (second) ratio of the axial extent of the skirt portion and the radial extent of the transition zone is greater than 0.85 and also less than 1.0.
  • the outer curl and the inner curl play "a role”.
  • This relates to particularly preferred ranges of the second ratio.
