Definitions
- the invention relates to a method for establishing a connection between components made of mutually different plastic materials according to the preamble of patent claim 1.
- the invention also relates to a container according to the inventive method prepared container with pouring attachment.
- the container and its neck are made, for example, of polyethylene terephthalate (PET), while the spout may consist of polypropylene (PP), for example.
- PET polyethylene terephthalate
- PP polypropylene
- PET belongs to the polar plastics and PP to the non-polar plastics. It is known from the prior art that a cohesive connection of these two plastics, generally of polar and nonpolar plastics, is not feasible with one another. In contrast, the welding of polar plastics with each other and of non-polar plastics is feasible.
- the usual in the past containers made of white or stained, glass or ceramic are increasingly being replaced by plastic containers.
- plastic containers are used for the packaging of fluid substances, such as beverages, flowable foods such as ketchup, sugo, pesto, sauces, mustard, mayonnaise and the like.
- fluid substances such as beverages
- flowable foods such as ketchup, sugo, pesto, sauces, mustard, mayonnaise and the like
- household products, toiletries, cosmetics, etc. now mainly plastic containers are used.
- the low weight and the lower costs certainly play a significant role in this substitution.
- the use of recyclable plastic materials, the use of bioplastics and the overall more favorable overall energy balance during their production also contribute to demand from the consumer for the acceptance of plastic containers, in particular plastic bottles.
- extrusion blown process a section of a single-layer or multi-layer extruded plastic tube is inserted into a mold cavity of a blow molding tool and inflated through a pressurized medium, usually air, to the desired container.
- a preform of usually elongated, tube-like shape is first produced in an injection molding process, which is closed at its one longitudinal end with a bottom and at the other longitudinal end has a neck portion.
- the preparation of the preforms can be done temporally and / or spatially separated from the subsequent blowing process.
- the produced preform is further processed without intermediate cooling immediately after its production. This can be done in so-called injection blow molding with the aid of a single mechanical system, on which the preform is injected, inflated to a container of the desired shape and demolded.
- the preform can also be stretched axially by means of a stretching mandrel.
- the main component ie 90% and more, for example, PET, PET-G, HDPE, PP, PS, PVC, PEN, PA, copolymers of the above plastics, bioplastics such as PLA, PEF or PPF, filled plastics and / or Mixtures of the plastics mentioned consists.
- the plastics or parts thereof may be colored and / or coated.
- Condition for the usable plastics is their suitability for the particular manufacturing process of the preform.
- the preform can already be used as a finished container.
- the container from the preform can be made by a subsequent stretch blow molding or by extrusion blow molding. Due to the different manufacturing process, the plastics used can be different.
- the plastic containers are often provided with different pouring spouts.
- the spout is intended to enable spill-free pouring, to simplify metering or to permit extensive spreading of the substance contained in the container.
- the use of a pourer also has the advantage that the same type of plastic containers can be equipped with a different pourer depending on the wishes of the bottler.
- the spout may be provided with means for closing the container.
- means may be provided on the container neck or on the pourer, which allow a positive connection, for example with a screw cap.
- the means may e.g.
- the spout is usually made of a plastic material other than the plastic material of the plastic container, e.g. a polyolefin, in particular PP, and is most often produced in an injection molding process.
- the object of the present invention is to provide a method and a container with a pouring element, with which components from mutually different plastic materials can be connected to one another.
- the method should be used, for example, for a fluid-tight connection of a pouring element with a blown plastic container as well as for a fluid-tight connection of the pourer with a preform produced by injection molding. Adhesives and / or additional mechanical fasteners should be able to be dispensed with. It is also intended to provide a corresponding container with an associated pouring element be, wherein the container and the pouring element consist of mutually different plastics.
- the invention proposes a method for establishing a connection between components made of mutually different plastics, in which a first portion of a first component and a second portion of a second component that is different from the first component are firmly connected to one another.
- the first portion of a first plastic whose main component is non-polar plastic
- the second portion of a second plastic whose main component is non-polar plastic, or vice versa.
- the connection between the first section and the second section of the first and the second component is created by means of irradiated laser energy.
- the first section acted on first by the irradiated laser energy is at least partially transparent to the incident laser energy.
- the irradiated laser energy is absorbed at least in part at least in a joining region in which the first and the second section abut each other under force and overlapping each other. In this way, a positive permanent connection is created between the two components, respectively the first section and the second section.
- the sections to be joined are formed from a polar and a non-polar plastic.
- the applied first of the two joining partners is locally heated and softened so far that the second plastic of the second joining partner is affected by the force acting on it, which is usually produced by prestressing, under a material. pushing the first plastic of the first joining partner into this first plastic hineinerstreckt.
- a form-fit is generated between the two joining partners, which can be additionally supported by a frictional connection.
- the material displacement, and thus the connection of the two parts to be joined may be substantially linear and / or planar. It is understood that the first portion and the second portion, which are generally both flat, overlap each other to form the connection.
- the connection produced between the first section and the second section is at least in the axial direction, ie under the action of shear forces, insoluble.
- the second joining partner respectively the second section of the joining partner, consist of a plastic which at least partially absorbs the irradiated laser energy. In this way the partial absorption beyond the joining region can also take place in the plastic of the second joining partner, respectively its second section , The at least partial absorption of the irradiated laser energy is thus not limited to the joining region.
- An additive can be arranged in the joining region, which assists the energy input into the two joining partners by at least partial absorption of the irradiated laser energy, so that the at least partial absorption of the irradiated laser energy onto the joining region can be limited.
- both joining partners for the irradiated laser energy are at least partially transparent.
- the additive or the plastic may have fillers which at least partially absorb the wavelength of the irradiated laser light.
- the additive may be applied to one of the joining partners or also to both joining partners, in particular in the joining region, or may be mixed into the plastic at least in the joining region.
