Definitions
- the invention relates to a plastic container with a pourer according to the preamble of patent claim 1.
- plastic containers are used for the packaging of fluid substances, for example for household, agricultural, industrial and commercial applications, etc.
- plastic containers are used for the packaging of fluid substances.
- the low weight and the lower costs certainly play a significant role in this substitution.
- the use of recyclable plastic materials and the overall more favorable overall energy balance in their production also contribute to promoting the acceptance of plastic containers among the users.
- Single-layer or multi-layered plastic containers are often produced by the so-called extrusion blow molding method, in particular a tubular blowing method.
- the extrusion blow molding machines used for the extrusion blow molding process usually have one or more extruders for feeding the required plastic material.
- the outlet of the extruder is connected to an extruder head, at the outlet opening of which the extruded tube preferably exits in the opening width.
- the extruded plastic tube can be constructed in one or more layers.
- the hose exiting the outlet nozzle continuously or quasi-continuously is transferred to a blow molding tool assembly and inflated by overpressure with the aid of a blow mandrel retracted into the mold cavity. Thereafter, the inflated plastic container is removed from the mold cavity.
- Plastic containers made of polyethylene terephthalate (PET) and similar materials are usually produced in a so-called stretch blow molding process.
- PET polyethylene terephthalate
- a cylindrical preform is first produced in an injection molding process in an injection mold.
- the preform has a substantially elongated cylindrical body and is formed closed at one longitudinal end.
- a support ring separates the body from a neck section with a pouring opening.
- the neck portion already has the later shape of the bottle neck.
- On the outside of the neck portion already threaded portions or the like can be formed for the determination of a closure part.
- the preform is demolded after its production and immediately further processed or stored for later processing on a stretch blow molder. Before further processing in a stretch blow molding machine, the preform is conditioned if necessary; then it is introduced into a blow mold of the stretch blow molding machine.
- the preform is finally inflated by means of a gas injected with excess pressure in accordance with the mold cavity and usually additionally drawn with a stretching mandrel.
- An injection blow molding process is also already known, in which the blowing process takes place directly after the injection 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 according to the mold cavity of a blow mold, which is delivered to the injection core or vice versa, and thereby stretched by the mandrel. Thereafter, the finished plastic container is removed from the mold.
- the plastic containers produced by extrusion blow molding or stretch blow molding are often provided with different pourers.
- the pourer is intended, for example, to enable spillage-free pouring, to simplify metering or to permit a spreading of the substance contained in the container.
- the use of a pourer also has the advantage that the same type of plastic container can be equipped with a different pouring spout, depending on the wishes of the bottler.
- the spout may be provided with means for closing the container. For example, a pivotable cover part is hinged to the top of the spout.
- pourers may also be provided which have an external thread or external thread sections which interact with the internal thread or with the internal thread sections of a rotary closure.
- the rotary closure in particular when screwing, it may happen that the pourer rotates due to the torque applied. This can complicate the screwing on the screw cap.
- the co-rotation of the spout above all can cause the spout no longer assumes its intended target position with respect to the container body, the compliance is currently required usually with an accuracy of + 15 °. On the part of the container manufacturer or the bottler therefore a considerable effort is currently operated to ensure the positional accuracy of the pourer and prevent twisting of the pourer in the operation of the rotary closure.
- the attached after the filling of the plastic container spout is glued to the container neck into which it is inserted.
- the adhesive used for gluing is undesirable when recycling the plastic containers and requires additional separation and purification steps. Even the gluing of the spout Using electrical welding techniques means a significant technical and financial effort.
- An alternative embodiment provides that the spout is pressed into the container neck after filling and is held there by frictional engagement.
- pourer is used immediately after the blow molding of the plastic container in the still hot container neck. When cooling the plastic container reduces the diameter of the container neck.
- Object of the present invention is therefore to remedy these disadvantages of the known from the prior art plastic container with pourer.
- the use of lubricants should be avoided.
- a plastic container and an associated spout are to be modified so that a simple assembly is possible. Additional fixation steps for the pourer should be avoided.
- a solution is sought which does not contradict the desire for an optimization of the plastic container in terms of its weight. It should create the conditions for the use of modified pourers with integrated or alternatively arranged closure devices.
- the invention provides a plastic container with a spout which can be mounted on a container neck and has one or more closable pouring openings.
- a cam is formed, which projects beyond a neck wall and formed in a blow molding process.
- the blow molding process may be an extrusion blown process or a stretch blown process.
- the spout has a body which can be connected to the container neck and which is formed corresponding to a peripheral contour of the container neck. In a wall of the body facing the neck wall provided with the at least one cam, a corresponding number of receptacles for the cam (s) are formed.
- the at least one cam formed in a blow molding process is formed in an inner wall of the container neck.
- the at least one receptacle on the body of the spout is provided correspondingly in an outer wall of the body of the spout.
- the spout equipped with at least one corresponding receptacle can be mounted in the usual manner rapidly on the container neck equipped with at least one cam, in particular can be opened up.
- the assembly of the spout on the container neck can be done in the usual way after filling; no technical modifications of the filling devices are required. Since the spout is held in a form-fitting manner after mounting on the container neck, it may have a slightly smaller diameter than the container neck. As a result, significantly smaller forces are required during assembly of the spout, and the plastic container does not have to have increased compression crush strength.
- the positive connection between the spout and the container neck can be designed to be movable over a certain circumferential area.
- the mobility is terminated and, for example, a rotary closure can be unscrewed from the pourer or screwed onto it.
- a rotary closure can be unscrewed from the pourer or screwed onto it.
- the positive connection between the spout and the container neck allows the Abandonment of an adhesive. This reduces the cost of manufacturing the container and facilitates recycling after use.
- the inventive design of the plastic container and the spout also makes it possible to dispense with sliding coatings of the pourer and / or a rotary closure.
- the spout On the inner wall of the container neck, one or more, for example two opposing, cams may be provided. Accordingly, the spout is equipped with a corresponding number of receptacles; For example, it has two opposing shots.
- the at least one cam produced in the blow-molding process is formed in the inner wall of the container neck and the at least one receptacle is formed in the outer wall of the body of the spout, a simple insert assembly of the spout is made possible.
- the at least one cam on the inner wall of the container neck does not constitute an obstacle to devices which, for example, are slipped over the container neck during filling. If the neck of the plastic container also has a thread or thread segments on its outer wall, it can also be used without a pourer and can be closed with a conventional screw cap. This increases the flexibility of the use of the plastic container.
- the at least one cam opposite the neck wall has a protrusion of 1, 3 mm to 8 mm. Their extension in the circumferential direction of the neck wall is about 3 mm to 8 mm.
- the position of the at least one cam is arbitrary.
- the at least one cam is located in a demolding plane of the blow mold.
- the plastic container is very easy to demold, especially when arranged in the inner wall of the container neck cams after inflation.
- the container neck a in the we- having significant rotationally symmetric peripheral contour. This is preferably circular.
- the at least one receptacle in the body of the spout extends to the free end of the body.
- an axial securing can be provided in the receptacle, which prevents removal of the spout or this allows only by destruction of the body.
- the at least one recording in a centering whose circumferentially measured extension widens in the direction of the free end of the body.
- the insertion bevels of the centering guide allow tolerances in the alignment accuracy of the pourer with respect to the container neck, in particular with respect to the order of the cams on the container neck, up to + 30 °.
- the at least one receptacle is designed as a slide guide for the at least one cam.
- the slotted guide runs in the circumferential direction and extends over an angular range of 45 ° to 90 °.
- This embodiment of the invention based on the basic principle of the positive connection of the spout and the container neck is provided in particular for pourers with alternative arrangements of the pouring spout (s) or with alternatively designed closing devices.
- the spout has a cover plate provided with a pouring opening, which can be brought into contact with the container neck by turning the pourer relative to the container neck with an opening provided on the container neck.
- the at least one receptacle in the body of the pourer is designed as a link guide for the at least one cam, which extends in the circumferential direction over an angular range of 45 ° to 90 °.
- the slide guide is arranged obliquely so that a rotation of the pourer relative to the container terhals results in an axial displacement of the spout from the container neck out or back again.
- the axial displaceability of the spout can facilitate the pouring process.
- this also allows alternative arrangements of the pouring opening (s).
- the spout has at least one pouring opening, which is arranged in the side wall of the body and is open only in the extended position of the spout. When withdrawn into the container neck spout the pouring spout is closed.
- Locking projections for the cam can be arranged at the two end sections of the sliding guide.
- the locking projections just protrude into the position of the cam so far that can be run over with relatively little effort.
- the locking projections ensure that the set relative position between the cam and slide guide does not change unintentionally.
- the plastic container with cam (s) on the container neck can be produced by extrusion blow molding or in a stretch blown from a separately manufactured preform. Prefabricated preforms, however, usually already have a fully formed neck portion with an external thread, which is not changed in the subsequent blow molding process. It is understood, however, that preforms without thread in the neck section can be prefabricated. The threaded sections can then be produced in the subsequent blow molding process by correspondingly shaped sliding parts.
- the at least one cam can then be created at the container neck.
- the embodiment according to the invention is preferably produced in an extrusion blow molding method which allows greater degrees of freedom with regard to the design of the neck section of the plastic container.
- the formation of the container neck takes place only in the blow mold.
