Definitions
- the invention relates to a refillable plastic container, in particular made of polyethylene terephthalate or polyethylene furanoate, according to the independent patent claims.
- plastic containers have recently been used mainly.
- the low weight and the lower costs certainly play a not inconsiderable role in this substitution.
- the use of recyclable plastic materials and the overall more favorable overall energy balance in their manufacture also help to promote the acceptance of plastic containers among users.
- Plastic containers especially plastic bottles, made of polyethylene terephthalate (PET) and similar materials are usually Herge using a so-called stretch blow molding process.
- a preform is first produced in an injection molding process in an injection molding process.
- flow molding or extrusion blowing processes have also been proposed for the production of preforms.
- the preform has an essentially elongated preform body and is designed to be closed at one of its longitudinal ends.
- An injection point originating from injection molding is usually also located there.
- a neck section which is provided with a pouring opening, adjoins the other end of the preform body.
- the neck section already has the later shape of the container neck.
- the preform body and the neck section are separated from one another by a so-called support ring.
- the support ring protrudes radially from the neck wall and is used to transport the preform or the plastic container made from it and to support the preform on the blow molding tool or the plastic container when it is closed with a cap.
- the preform is removed from the mold after its production and can be processed immediately while still hot in a single-stage stretch blow molding process.
- the preform is cooled and temporarily stored on a stretch blow molding device for spatially and / or temporally separate further processing. Before further processing in the stretch blow molding device, the preform is then conditioned if necessary, that is, a temperature profile is impressed on the preform.
- the preform is finally blown into the mold cavity using a gas, usually air, which is blown in with excess pressure and is additionally stretched axially with a stretching mandrel.
- a gas usually air
- An injection blow molding process is also already known in which the stretch blow molding process takes place directly after the injection molding of the preform.
- the preform remains on the injection core, which at the same time forms a kind of stretching mandrel.
- the preform is in turn inflated by overpressure in accordance with the mold cavity of a blow mold that is fed to the injection core or vice versa and is stretched by the stretching mandrel.
- the finished plastic container is then removed from the mold.
- Stretch-blown or injection-blown plastic containers can be identified on the basis of the injection point, which is usually arranged in the area of the container bottom and originates from the preform. At this injection point, the plastic material is only slightly stretched or not stretched at all.
- PET polyethylene terephthalate
- PET polyethylene terephthalate
- PET has been tried and tested, its chemical, physical and mechanical properties are well known, and it can be easily processed on the known systems.
- the recycling cycles that have been introduced and are constantly being expanded ensure that the majority of the PET containers can be collected again after use and reprocessed.
- plastic containers made of polyethylene furanoate (PEF) have also been produced, which are distinguished from PET in particular by their better barrier properties. In terms of mechanical strength, plastic containers made of PET and PEF have very similar properties.
- polyesters especially PET and PEF
- stress cracks in the plastic container can form points of attack for the lye, at which the plastic can degrade over time.
- a reaction between ester and alkali can lead to saponification. This can discolour the plastic container and ultimately even cause it to fail.
- the unstretched areas of plastic containers, in particular the neck of a plastic container are particularly susceptible to such stress-induced problems.
- stretch blow molding a preform made of PET or PEF, which is usually produced in an injection molding process, the neck of the preform is located outside the blow mold and is not stretched during the stretch blow molding process and is therefore not stretch-hardened.
- Tensions in the neck of the plastic container can lead to microscopic cracks, which can enlarge when the container is cleaned with alkaline solutions. This can lead to the neck of the plastic container showing leaks over time or being unable to withstand an internal pressure in the plastic container, for example caused by carbonated beverages.
- the tensions in the neck of the plastic container can be of various kinds. For example, this includes thermal voltages that can occur due to the different expansions of the inner wall and outer wall of the neck of the container. Further stresses can be induced during the manufacture of the plastic container from the preform by the blow nozzle and by the stretching mandrel with which the preform is axially stretched.
- the object of the present invention is therefore to remedy one or more disadvantages of the plastic containers of the prior art.
- the prerequisites for a refillable plastic container are to be created that allow a greater number of cleanings and refills.
- a refillable plastic container according to the invention in particular a refillable plastic container made of PET or PEF, has a neck with a neck opening and a container body enclosing a filling volume, which are separated from one another by a substantially radially protruding support ring.
- the neck of the plastic container has an axial length measured from an underside of the support ring to a mouth rim bordering the neck opening, which is equal to or less than 17.25 mm.
- the neck has a minimum wall thickness that does not fall below 1.9 mm.
- the invention proposes optimizations of the neck of the plastic container in order to minimize the stresses that occur during production in the undrawn area of the container .
- thermal stresses due to different contractions of the inner wall and outer wall of the neck during manufacture for example in an injection molding process, can be reduced.
- Due to the overall thick-walled training The neck also cools down more slowly and more evenly during production, which can significantly reduce the formation of tension.
- Lower stresses in the manufacture of the preform lead to a significantly smaller number of microscopic cracks in the neck of the plastic container. This enables a greater number of cycles of filling, cleaning and refilling of the plastic containers.
- the neck can be designed with positive engagement elements, in particular threaded sections, which protrude as radial projections from an outer wall of the neck in a neck section located between the mouth edge and the support ring.
- these projections extend over at least 85% of a circumference of the neck.
- An associated closure cap can be designed, for example, as a twist lock or as a bayonet lock, which has essentially complementary engagement elements.
- Such a cap is assembled by applying pressure and applying a torque.
- the interlocking A grip elements extend over at least 85% of a circumference of the neck.
- sealing caps in particular rotary fasteners, are provided with a tear-off guarantee strip.
- an at least regionally circumferential, essentially radially protruding from the outer wall of the neck is formed on a section of the neck, which is located between an end of the interlocking engagement elements closer to the support ring and the support ring.
- a lying between the abutment and the support ring Be rich of the neck is usually used in the manufacture of the container for the attack of transport elements, such as transport tongs.
- this loading area in particular only this area, has a minimum wall thickness that does not fall below 1.9.
- the neck has an inner wall designed as a conical sealing surface in an area located between the interlocking engagement elements and the support ring.
- the sealing surface is thereby axially displaced away from the mouth edge in the direction of the interior of the plastic container and is formed in a region of the neck which isaded det with a greater wall thickness. In cooperation with a closure cap with a correspondingly elongated sealing cone, this leads to a reduction in the stresses in the container neck.
- a further aspect of the invention therefore relates to a closure cap, in particular a closure cap for use with a plastic container as described here, which has a cover plate and an essentially cylindrical jacket formed thereon with form-fitting engagement elements, in particular threaded elements, which are formed with correspondingly form-fitting engagement elements, in particular threaded sections, cooperate on the neck of the plastic container.
- a closure cap in particular a closure cap for use with a plastic container as described here, which has a cover plate and an essentially cylindrical jacket formed thereon with form-fitting engagement elements, in particular threaded elements, which are formed with correspondingly form-fitting engagement elements, in particular threaded sections, cooperate on the neck of the plastic container.
- Within a space enclosed by the jacket is a concentric to the jacket of ordered, ring-shaped circumferential spacer which protrudes from the cover plate and at the free end of which a sealing lip is arranged.
- the spacer and the sealing lip have a maximum axial extent which is equal to or greater than the height of
- an inside diameter of the neck measured at the neck opening is less than 21.6 mm.
- the inside diameter in the area of the neck opening is larger than the inside diameter of the neck in the area of the support ring.
- the formation of the support ring with an axial thickness of 1.9 mm to 2.5 mm measured at the transition to an outer wall of the neck also helps to reduce the stresses.
- the neck can have a wall thickness, measured at the edge of the mouth, which is 1.4 mm to 1.8 mm.
- the nozzle is pressed with a constant pressure against the mouth edge of the neck of the container. Since the neck has a wall thickness of 1.4 mm to 1.8 mm measured at the mouth edge, especially in connection with a smaller diameter compared to the known necks of disposable plastic containers, the force acting on the neck can be reduced or better taken up. This avoids stresses and the resulting micro-cracks in the material
- the geometric optimizations of the container neck to reduce the stresses occurring during production and assembly can also be supported in a further variant of the invention by adding suitable additives to the plastic material.
- suitable additives from the group consisting of terephthalic acid (PTA), isophthalic acid (IPA), monoethylene glycol (MEG), diethylene glycol (DEG), Isosor bit, spiroglycol and naphthalenedicarboxylic acid dimethyl ester (NDC) proves to be expedient.
- the refillable plastic container can be designed as a preform which is produced in an injection molding process or in an extrusion process.
- the refillable Kunststoffbe container is designed as a container which is manufactured in a blow molding process from a preform produced in an injection molding process or in an extrusion molding process. It is preferably designed as a stretch-blown container.
- the closure cap can be designed as a twist lock or a bayonet lock.
- closures made from a plastic from the group consisting of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), their copolymers, and thermoplastic elastomers (TPE) have proven advantageous. are made.
- the pairing of the PET container material with the listed closure materials can also help to reduce the occurrence of tension in the neck of the plastic container.
- a closure cap designed accordingly for use with a refillable plastic container designed according to the invention has a cover plate and an essentially cylindrical jacket formed thereon with form-fitting engagement elements, in particular threaded elements, which interact with correspondingly formed form-fitting engagement elements, in particular threaded sections, on the neck of the plastic container .
- form-fitting engagement elements in particular threaded elements
- correspondingly formed form-fitting engagement elements in particular threaded sections
- the spacer and the sealing lip have a maximum axial extent that is equal to or greater than a maximum distance between the form-fitting engagement elements and the cover plate.
- the closure cap is designed to interact with a conical sealing surface that is moved in the direction of the support ring into the interior of the neck of the refillable plastic container and therefore has a sealing lip arranged on a spacer.
- the maximum axial extension of the spacer and the sealing lip can in some embodiments Variants of the invention can even be greater than an axial length of the casing of the closure cap.
- the sealing lip is designed to be circumferential and has an approximately trumpet-shaped axial cross section.
- the free end of the sealing lip pointing outwards and in the direction of the cover plate of the closure cap rests against the inner wall of the neck of the plastic container in the assembled state of the closure cap.
