Description
Technical field
The present invention relates to a kind ofly according to claim 1 as described in the preamble, have the plastic container of toppling over part.
Background technology
Commonly used by tin-plate or non-ferrous metal board, by plastic container, substituted more and more by glass or the container also made by pottery in the past.Particularly, for the packing of flowing material, such as the application in housekeeping, in agricultural, industry and business etc., recently mostly use plastic container.Little weight and lower cost play an important role undoubtedly in described replacement.The application of callable plastic material and in it is manufactured generally more favourable global energy balance also help lend some impetus to and in application, approve plastic container.
One or more layers plastic container are usually in so-called extrusion and blow molding method, particularly manufacture in the flexible pipe blow molding method.For the extrusion blow molding machine of extrusion and blow molding method, usually have one or more extruders with for delivery of needed plastic material.The outlet of extruder is connected with cross-head, and preferably can regulating on the outlet nozzle of opening size of described cross-head, the flexible pipe of extruding occurs.The plastic hose of extruding can be configured to one or more layers.From the flexible pipe occurred continuously or in continuous approximation outlet nozzle, be transmitted to the blow molding tool device and be inflated by superpressure by means of the air blast core that enters into mould cavity.After this, by the inflation plastic container from the demoulding die cavity.
By the plastic container that polyethylene terephthalate (PET) and similar material are made, mostly in so-called stretch blow-molded method, manufactured.At this, at first in injection molding process, manufacture columniform preform in injection mould.Extrusion process for the manufacture of preform is also proposed recently.Preform have micro-length basically, columniform body and constitute and seal on longitudinal end.Support ring separates body and the neck section with pouring opening.Neck section has had bottleneck shape after a while.On the outside of neck section, can form threaded portion section etc. with for the fixed stop part.By preform after it is manufactured demoulding and reprocessing at once or deposit temporarily with for after the processing on stretch blow moulding.Before in stretch blow moulding, reprocessing, preform is adjusted in case of necessity; After this, preform is incorporated in the blow mold of stretch blow moulding.In blow mold, final, preform is inflated according to die cavity by the gas be blown into by superpressure, and mostly additionally by the stretching core, is stretched at this.The injection blow molding forming process has been also known, and wherein blow-moulding process directly carries out after the injection preform.At this, preform is retained on the injection core, and described injection core forms the type of stretching core simultaneously.Preform is inflated according to the die cavity of blow mold by superpressure again, on the contrary described blow mold is sent on the injection core or, and at this, described preform is stretched by the stretching core.After this, by the plastic container demoulding of making.
According to the type of the material that will topple over, in the extrusion and blow molding method or the plastic container of manufacturing in stretch blow-molded method be typically provided with the different parts of toppling over.For example, toppling over part should realize simplifying dosage or allowing to take out reposefully the material be included in container without toppling over of splashing.Except being adapted to various materials, the application of toppling over part also has following advantage, and the plastic container of same kind can be equipped with the different parts of toppling over according to the requirement of tank shape machine.Topple over part and can be equipped with the device of the stop that can realize container.For example, for this reason, toppling over hinged pivotable cover on the upside of part.But, also can be provided with the part of toppling over outside thread or external thread part section, the negative thread of described outside thread or external thread part section and rotation lock part or the combined action of internal thread part section.
When operation rotation lock part, particularly, when turning on the rotation lock part, can occur: topple over part because the torque applied is rotated together.This can add to the difficulties to turning on the rotation lock part.Yet the rotation together of toppling over part especially can cause: topple over part and no longer occupy it about vessel and default theoretical position, usually require at present the precision with ± 15 ° to keep described theoretical position.Therefore, from the aspect of container builder or bottle placer, spent at present a large amount of expending, in order to guarantee, toppled over the positional precision of part and when operation rotation lock part, prevent from toppling over the torsion of part.
In an embodiment variations, after filling plastic container, by suit to topple over the container neck that part is inserted into it wherein bonding.Except additional expend and additional cost, for bonding lining cement, when the recycled plastic container be do not expect and need additional separation and cleaning.Topple over bonding technology and the economic drain also meaned much more very by means of the electric welding technology of part.
The embodiment variations of an alternative is provided with, and will topple over part and be pressed in container neck and by frictional connection and remain on there after filling.In order to overcome toppling over the friction force of part while being pressed in container neck, apply relatively large power.This causes plastic container must sustain the compressed pressure increased.In order to ensure this point, plastic container must have larger wall thickness and then manufacture with larger container weight.Thus, improve significantly the price of manufacturing plastic container.
In another embodiment variations, will topple over part and after the blow molding of plastic container, directly be inserted in still hot container neck.When the cooling plastic container, the diameter of container neck reduces.Thus, container neck almost shrink fit to toppling on part.Thus, topple over part in fact by immovably fixing about its position.Yet the shortcoming of this embodiment variations is, must passes and topple over part and carry out container filling.Thus, reduced filling speed.According to the design of toppling over part, also can need the equipment change added, this plays negative effect to cost.
No matter be after manufacturing container, install at once or just install after filling toppling over part, in each situation, all must topple over the very careful aligning of part about the body of container.
Part rotates together when turning on the rotation lock part the problem of toppling in order to prevent from installing, also propose, rotation lock part and/or topple over part and be provided with lubricant, and particularly coating has lubricant.Described lubricant must with respect to weighting material be inertia and the situation of food that be especially in use in the customer under be harmless.The selection of the lubricant therefore, be applicable to is relatively limited.Lubricant is applied to the rotation lock part and/or topples on part and require additional expending and additional cost.
Summary of the invention
Therefore, the object of the invention is to, to from the shortcoming with the plastic container of toppling over part well known in the prior art, remedying.Can abandon making with lubricator.Plastic container and be associated topple over part and should change as follows, make it possible to realize simple installation.Can abandon be used to toppling over the additional fixing step of part.Also can abandon can causing the lining cement expended added when the recycled plastic container.At this, expect following solution, described solution with to plastic container in the contradiction not of the optimized expectation aspect its weight.Should set up the condition precedent of toppling over part that uses the change with latching device one or that arrange as an alternative.
The solution of described purpose is to have the plastic container of toppling over part, and described plastic container have the feature of enumerating in the characteristic of claim 1.Improved form of the present invention and/or favourable embodiment variations are the themes of dependent claims.
By the present invention, complete a kind of plastic container of toppling over part that have, describedly topple over part and can be installed on container neck and have the one or more pouring openings that can close.On container neck, form at least one projection, described projection protrudes from the neck wall and forms in blow molding method.Blow molding method can be extrusion and blow molding method or stretch blow-molded method.Topple over part and have the body that can be connected with container neck, described body forms in the mode that the circumferential profile with container neck is complementary.The accommodation section for projection that forms respective numbers in the wall of the neck wall that is provided with at least one projection at body.Be different from from plastic container well known in the prior art, at least one projection formed in blow molding method is formed in the inwall of container neck.At least one accommodation section of toppling on the body of part is located in the outer wall of the body of toppling over part therewith matchingly.
Toppling over part and can being installed to rapidly with usual way, particularly suppressing on the container neck that is equipped with at least one projection of at least one accommodation section be complementary be equipped with.Toppling over part can carry out in common mode in the installation on container neck after filling; This does not need the technology change of filling apparatus.Because topple over part, remain on container neck to form fit after it is installed, so described, topple over part and can have and with container neck, compare smaller diameter.Thus, when part is toppled in installation, need obviously less power, and plastic container needn't have the compressive resistance of raising.It is movable that the connection of toppling over the form fit between part and container neck can constitute on certain circumferential scope.Yet, as long as at least one projection is encountered the circumferential edge of accommodation section, finish so mobility and for example the rotation lock part can turn on or tighten to and describedly topple on part from toppling over part.The connection of toppling over the form fit between part and container neck allows to abandon lining cement.This has reduced manufactures the expense of container and has simplified the recovery after it uses.Plastic container and topple over part according to design plan of the present invention, also allow to abandon toppling over slip coat part and/or the rotation lock part.
On the inwall of container neck, can be provided with one or more, two projections of putting toward each other for example.Correspondingly, topple over the accommodation section that part is equipped with respective numbers; Topple over part and for example have two accommodation sections of putting toward each other.
By at least one projection of manufacturing in blow molding method, be formed in the inwall of container neck and at least one accommodation section is formed in the outer wall of the body of toppling over part, can realize that the simple use of toppling over part installs.At least one projection on the inwall of container neck does not reveal obstruction to the equipment list that for example cover installs on container neck when filling.If have screw thread or threaded portion section on this external its outer wall of the neck of plastic container, so described plastic container also can be in the situation that do not topple over part use and can be closed by traditional rotation lock part.This has improved the use alerting ability of plastic container.
In order to prevent from toppling over the inordinate rotation of part when operating the spiral locking piece, at least one projection has the height that exceeds of 1.3mm to 8mm with respect to the neck wall.Described projection extends to about 3mm to 8mm on the circumferential direction of neck wall.The position of at least one projection can freely be selected.Yet, due to manufacture, turning out to be advantageously, at least one projection is arranged in the demoulding plane of blow mold.Thus, especially in the situation that during projection was arranged on the inwall of container neck, plastic container can the demoulding easily after inflation.
Due to the symmetry reason and for fear of container and the additional aligning of toppling over part, turn out to be advantageously, container neck has rotational symmetric circumferential profile basically.It is circular that described circumferential profile preferably constitutes.
In order to simplify, topple over the installation of part on container neck, extend until the free end of body at least one accommodation section of toppling in the body of part.Additionally, can be provided with axial fender guard in accommodation section, described fender guard stops to pull out to topple over part or allow only pulls out and topples over part by the damage body.
In order to reduce in order to install expending be used to the aligning of toppling over part, in another embodiment of the invention variations, at least one accommodation section is led in the centering guide portion, the expanding extending on the free-ended direction of body of measuring on circumferential direction of described centering guide portion.According to the axial length of body, the importing inclined-plane of centering guide portion allow to topple over part about container neck, particularly about projection the alignment precision of the layout on container neck until ± tolerance of 30 °.
In another embodiment of the invention variations, at least one accommodation section constitutes the chute guide portion at least one projection.The chute guide portion is stretching on circumferential direction and is extending on the angular range of 45 ° to 90 °.Based on this embodiment variations of the present invention of the groundwork of the connection of the form fit of toppling over part and container neck, especially be made as be used to alternative setting with pouring opening or have the part of toppling over of latching device that alternative forms.For example, topple over part and have the cover plate that is provided with pouring opening, described cover plate can be by toppling over part with respect to the torsion of container neck and the superposition of end gap be located on container neck.
Another embodiment with the plastic container of toppling over part proposes, at least one accommodation section of toppling in the body of part constitutes the chute guide portion at least one projection, and described chute guide portion is being extended on circumferential direction on the angular range of 45 ° to 90 °.At this, the chute guide portion is arranged in the mode of slant dilation, makes to topple over part and cause that with respect to the torsion of container neck toppling over part moves axially to leave container neck or move axially and again be back to container neck.Topple over the axially movable performance of part and enough simplify toppling process.But this also can realize the setting of the alternative of pouring opening.For example, topple over part and have at least one pouring opening, described pouring opening is arranged in the sidewall of body and only in toppling over the extended position of part, opens.Topple over part be retracted into container neck in the time, pouring opening is closed.
On two end segments of chute guide portion, can be provided for the stop salient of projection.The stop salient just extend in the location path of projection so far away, makes it possible to expend and cross described stop salient by relatively little power.Yet the stop salient is used for: the relative position of setting between projection and chute guide portion does not unexpectedly change.
The plastic container that have projection on container neck can be in the extrusion and blow molding method or also in stretch blow-molded method by the preform manufacture of making separately.Yet prefabricated preform has had the externally threaded neck section that has be shaped fully usually, described neck section no longer changes in blow-moulding process subsequently.Yet, it being understood that also and can in neck section, not have in advance threaded preform.So, the threaded portion section can be manufactured by the sliding part by corresponding shaping in blow-moulding process subsequently.At this, so, at least one projection also can be manufactured on container neck.Yet, according to embodiment of the present invention, preferably in the extrusion and blow molding method, to manufacture, described extrusion and blow molding method can realize higher degree of freedom aspect the design plan of the neck section of plastic container.Especially, in the extrusion and blow molding method, the formation of container neck is only carried out in blow mold.
The part of toppling over that has at least one accommodation section in its body is suitably manufactured in the favourable injection molding method of cost.
