Description

The sealing arrangement and the manufacture method thereof that are used for container
The present invention relates to be used for the sealing arrangement and the manufacture method thereof of container.
The sealing arrangement that is used for container is made such as cork with natural material usually.They are used for the temporary sealing container to prevent to overflow and to preserve the article in the container.They are attractive and effective usually.They are applied to Wine bottle seal cover in large quantities, and also are applied to other food materials and other material such as makeup.Yet they have relatively costly shortcoming, and be labour-intensive when producing, and are easy to take place quality error, and can mix germ and other impurity to the article of storage.These shortcomings have been realized for a long time, and use the synthetic substitute of neoprene and plastics to be developed out.Yet these makeshifts have such shortcoming: more expensive than natural material, be not easy to utilize again, and outward appearance is different with natural material with feel and have different performances with natural material.The consumer alert has so just reduced the acceptability of these makeshifts on market to these differences and be reluctant to use.Therefore, need a kind of synthetic leakproofing material, its outward appearance, feel and performance are similar to natural material, but that it has price is low, steady quality, and aseptic advantage.
In EP-A-0496194, describe and applied for a kind of sealing arrangement that is used for liquid container, be characterized in, it comprises the columniform substantially plastics constituent element made from expanded polystyrene, and wherein axially embedding one also is the elastic insert made from cork of general cylindrical.Yet owing to there is natural cork to exist, from lacking the viewpoint of sterilization, from the viewpoint of structure integrity, and from the viewpoint of the elastic performance of deficiency, this design-calculated sealing seems to have serious falling back.And though point out that the price of this product is low in the description that patent describes in detail, the labyrinth of this product will show it is opposite.
Therefore, for cork sealing, still need a kind of gratifying makeshift to be used for container, especially for liquid container such as bottle.
For this reason, the object of the present invention is to provide that a kind of price is low, steady quality and the aseptic sealing arrangement that is used for container, and the manufacture method that a kind of sealing device is provided.
According to the present invention, a kind of sealing arrangement that is used for container is provided, this device comprises the body of a round section, it is applicable to the opening that is installed in container, to seal described container, described body comprises a molded foam consolidation particulate polymers substantially, and this poly-mer is an expanded polystyrene, it has substantially density uniformly, is at least 0.03 gram per centimeter 3
Advantageously, described body is compressed processing, to improve its elasticity.
Advantageously, described body is roughly cylindrical.
Advantageously, described expanded polystyrene is colored, so that the color similarity of sealing arrangement and natural cork.
Advantageously, described sealing arrangement has the surface, and leakproofing material is partly or entirely coated on this surface, for example polyurethane resin and/or wax, and they have color, so that make the color similarity of sealing arrangement and natural cork.
Advantageously, the surface of described sealing arrangement is by physical treatment, for example: scraping, frosted or veining make its outward appearance and natural cork approaching.
Advantageously, described sealing arrangement is coated with and/or brushes material in its surface.
In addition, the present invention also provides a kind of manufacturing to be used for the method for the sealing arrangement of container, this method is included in steam compacting expanded polystyrene bead in one or several cylindrical die, so that the density of the mechanograph of evenly producing in model is at least 0.03 gram per centimeter 3Mechanograph is removed subsequently, then, if desired, the mechanograph burring, and be cut into the needed length of sealing arrangement, and if necessary, mechanograph can or be cut into the required size trailing portion before being cut into required size or coat leakproofing material fully, for example polyurethane and/or wax.
Advantageously, in said method, described mechanograph is compressed processing, to improve its elasticity.
Advantageously, in said method, described mechanograph need be compressed by roll extrusion under pressure, so that reduce their diameter.
Specific embodiments of the invention will be described by example in conjunction with the accompanying drawings, wherein:
Fig. 1 is the block diagram of sealing arrangement, and it is as the makeshift of bottle cork.
Fig. 2 illustrates sealing arrangement and is placed on situation on the bottle.
Referring to accompanying drawing, sealing arrangement comprises an expanded polystyrene cylinder 1, and it has greater than 0.03 gram per centimeter 3The uniform density of cardinal principle.Under so high density, the penetrablility that expanded polystyrene shows as gas, water vapour and other liquid greatly reduces.The anti-alcohol of expanded polystyrene, and be the material that allows the contact food material.It does not react with biology, plays barrier effect, stops the intrusion of bacterium and mould.In addition, just as noted above, in higher density ratio as 0.03 gram per centimeter 3It compares also more favourablely on density with cork when above, and its micro-structure is also similar to the cork shape.The texture of outside face 2 is also the spitting image of cork, and this handles such as by scraping, sand milling or veining etc. by dyeing and/or surface physics, can obtain satisfied raising.Frictional behaviour between highdensity expanded polystyrene and the glass is better than the frictional behaviour between cork and the glass.Yet, it should be noted that cork depend on to a certain extent absorb the content in the container liquid so that reach effective sealing, and sealing arrangement of the present invention to liquid without any tangible absorption.
As this field was well-known, expanded polystyrene used the suspension polymerization technology to produce by bead technology usually.Foaming agent is such as about 6% low boiling ligroin cut, normal pentane or mixed before polymerization or after polymerization for example, bead in heating and add depress saturated.Then bead is by the processing of steam mould.Bead is at first by heating prefoam in the steam pond.Make bead expand like this and continue to expand up in mould, reaching suitable level according to needed density.This will decide by the thermocouple of suitable placement, and this thermocouple is provided for making when reaching this point steam to close.Expanded beads was placed 24 hours, made its cool to room temperature and make in the air admission particle, so that make the condition of particle and outside reach balance.
Then, carry out the steam molding process.Bead is placed in the mould with foraminate wall, and it can make steam enter.Model is fair full by bead fully.Then steam enters and bead is further expanded and they are combined togather, and occupies the space of model.
When the body of sealing arrangement is roughly when cylindrical, model itself be shaped as the cylinder that a plurality of inside connect together, each cylinder can be several times of the length of the sealing arrangement made.
After mechanograph is finished, mechanograph is taken out from mould, remove burr, be cut into suitable length, coating colour adds texture, is coated with coating, coats an amount of paraffin.
Certainly, should be understood that above-mentioned concrete steps can change in many aspects under the situation that does not depart from the scope of the invention.
If the diameter of mechanograph is enough little, the sealing arrangement of making can directly insert container such as bottle.Yet, draw intensity owing to will increase, will use larger-diameter mechanograph, it will reduce size by compression before putting into traditional soft stopper insertion mouth, for example by roll extrusion.
It is to be noted, because expanded polystyrene does not have the such elasticity of cork, consider the difference of elasticity and corresponding expansion, usually need to adjust the cork embolus, the diameter that is generally 16mm from the traditional soft stopper is adjusted to for sealing arrangement diameter of the present invention such as 18mm.
Just as noted above, the sealing device should compress processing, for example by roll extrusion, improves the elasticity of polystyrene.When sealing arrangement is inserted into bottle 4, be compressed, provide sealing glass bottle.When extracting, what the elastic deformation of sealing device and real cork produced when bottle takes out feels closely similar, and allows the sealing device to turn back to again if desired.The sealing device keeps rigidity, and therefore, when being pushed into bottle 4, it keeps mechanical strength to be bent and deformed to prevent sealing arrangement, and provides fulcrum to extracting apparatus.In fact impermeable gas and the liquid that resembles in the wine of this highdensity expanded polystyrene.In addition, by with the impervious coating that does not have color, can provide supplementary protection such as polyurethane 5 processing ends and/or side.
Therefore, as explaining above, sealing arrangement of the present invention fully by expanded polymer consolidation grain composition, is preferably expanded polystyrene basically, and it has fixing whole in 0.03 gram per centimeter basically 3Density, and its part or all of surface can coat impervious leakproofing material, for example polyurethane and/or wax, with stop by and round the motion of the moisture and the gas of sealing arrangement.
