Description

       

  "Vat in het bijzonder biervat"

  
De uitvinding heeft betrekking op een vat, in het bijzonder een biervat, met een aan één einde open, het vatlichaam

  
vormend uit kunststof vervaardigd eerste doel en een eveneens

I

  
uit kunststof vervaardigd tweede deel dat met een omtreksrand afdichtend binnen het open einde van het eerste deel is aan-  gebracht. 

  
Dergelijke vaten zijn op zich bekend. Zij hebben het voordeel dat door een eenvoudige wijziging van de bij het spuitgieten gebruikte matrijs mogelijk is vatlichamen met de-

  
 <EMI ID=1.1> 

  
door combinatie van verschillende dergelijke uit één stuk be-  staande delen met steeds eenzelfde einddeel uit slechts twee  delen bestaande vaten met onderling verschillende inhoud kunnen worden verkregen. Bovendien kunnen dergelijke vaten worden vervaardigd met een cilindrische vorm die overeenkomt met de vorm

  
 <EMI ID=2.1> 

  
gebruikers het voordeel heeft dat de transport- en opslagmiddelen niet aan de nieuwe vaten behoeven te worden aangepast.

  
 <EMI ID=3.1> 

  
rompgedeelte overgaat in het einddeel het zwaarst belast. Voor het een geheel met het vatlichaam vormend einddeel is de dimen-

  
 <EMI ID=4.1> 

  
bij spuitgieten zonder meer mogelijk er door geschikte maatregelen voor te zorgen dat op zwaar belaste plaatsen extra mate-

  
 <EMI ID=5.1> 

  
kerd. Een groter probleem is echter het afsluitend aanbrengen van het tweede einddeel binnen het open einde van het vatli-

  
 <EMI ID=6.1> 

  
kerd, doch bovendien moet de overgang tussen beide delen blijvend volkomen gas- en vloeistofdicht zijn.

  
De uitvinding beoogt een oplossing voor dit probleem te verschaffen. Het vat volgens de uitvinding wordt hiertoe daardoor gekenmerkt, dat het vatlichaam zich nabij het open einde via een overgangsrand voortzet in een gedeelte met vergrote diameter waarbinnen nauw passend een cilindrische omtreksrand van het tweede deel is opgenomen, waarbij de omtreksrand van

  
 <EMI ID=7.1> 

  
stand der delen daartussen een ligplaats voor een afdichtingsring aanwezig is, terwijl de omtreksrand van het einddeel en

  
 <EMI ID=8.1> 

  
 <EMI ID=9.1> 

  
deze delen aangebrachte, op supersonische wijze gevormde las-

  
t el, verbindingen.

  
Hierdoor wordt bereikt, dat in de geassembleerde toestand een goede afdichting tussen de bij voorkeur onder voorspanning tegeu elkaar gelegen rand- en wanddelen der beide delen bij een grote sterkte van het vat wordt verkregen. Bovendien kan de afdichtin.gsring, onder behoud van de afdichtende eigenschappen, meer of minder worden samengedrukt voordat de puntlassen worden gevormd; de daaruit resulterende variatie van het netto volume

  
 <EMI ID=10.1> 

  
vorming van de lessen en de ring meer of minder samen te drukken tot het vat het juiste volume heeft, waarna de lassen worden gevormd.

  
Het assembleren van de delen wordt vergemakkelijkt wanneer

  
 <EMI ID=11.1> 

  
en de buitenwand van de cilindrische rand van het tweede deel enigszins taps verlopen.

  
Bij voorkeur wordt voorts gezorgd dat van het als cilindrisch lichaam uitgevoerde eerste deel de buitendiameter van het onverwijde einddeel in hoofdzaak gelijk is aan de binnendiameter van het verwijde einddeel, zodanig dat de vaten in elkaar passend kunnen worden gestapeld.

  
De uitvinding wordt toegelicht aan de hand van de bijgevoegde figuur die een halfaanzicht - halflangsdoorsnede van een vat volgens de uitvinding toont.

  
In de figuur is het vat in zijn geheel met het verwijzingscijfer 1 aangegeven. Het bestaat uit een, het vatlichaam vor-

  
 <EMI ID=12.1> 

  
bracht einddeel 3. Beide delen zijn door spuitgieten uit kunststof vervaardigd; het deel 2 is cilindrisch en is voorzien van de één geheel daarmee vormende rolranden 3a, 3b, 4a, 4b. De ruimte tussen de rolranden 3a, 3b resp. 4a, 4b kan, zoals met  stippellijnen aangegeven, indien gewenst, met een kunststofschuim zijn gevuld.

  
Binnen de cilindrische bovenrand 5 van het vatlichaam 2, waarvan de diameter overeenkomt met die van het vatlichaam zelf, bevindt zich het één geheel met het vatlichaam vormend, gewelfd afsluitdeel 6 met het spongat 7 dat op de gebruikelijke wijze

  
 <EMI ID=13.1> 

  
waardoor het bij het reinigen van het vat gebruikte spoelwater kan wegvloeien.

  
Het ondereinde van het vatlichaam 2 zet zich via een overgangsrand 11 voort in een cilindrische eindrand 12 met een ten opzichte van het vatlichaam 2 vergrote diameter. Daarbinnen past de cilindrische eindrand 13 van het einddeel 3. De beide delen kunnen enigszins taps zijn uitgevoerd.

  
Een aantal supersoon gevormde puntlassen 15, 16 is in twee rijen langs de omtrek van de cilindrische eindrand 12 en de eindrand 13 aangebracht; zij geven een onwrikbare verbinding tussen deze delen op een aantal punten. Een dergelijke supersonische puntlas wordt gevormd door een niet getekend penvormig gereedschap, dat zodanig wordt bekrachtigd dat het vibreert met een supersonische frekwentie tegen het buitenoppervlak van de rand 12 te drukken. De opgewekte hitte doet het kunststofmateriaal van het eerste deel 12 en daarna van het deel 13 in een gebied (aangegeven met het verwijzingscijfer 14) rond het gereedschap smelten; de kunststof van de beide delen vloeit in en door elkaar en na het terugtrekken van het gereedschap en het daarop volgend afkoelen en verharden van het materiaal wordt een perfecte en bijzonder sterke onderlinge verbinding verkregen.

    Door het gebruik van geschikte machinerie kan een aantal derge-

  "Vat in particular beer keg"

  
The invention relates to a keg, in particular a beer keg, with the keg body open at one end

  
molded plastic first target and a likewise

I.

  
second part made of plastics material which is sealingly disposed within the open end of the first part with a peripheral edge.

  
Such vessels are known per se. They have the advantage that a simple modification of the mold used in injection molding allows barrel bodies with the

  
 <EMI ID = 1.1>

  
By combining different such one-piece parts with the same end part each time, only two-part drums with mutually different contents can be obtained. In addition, such vessels can be made with a cylindrical shape to match the shape

  
 <EMI ID = 2.1>

  
users have the advantage that the means of transport and storage do not have to be adapted to the new drums.

  
 <EMI ID = 3.1>

  
trunk part transitions into end part most heavily loaded. For the end portion integral with the vessel body, the dimension is

  
 <EMI ID = 4.1>

  
with injection molding it is absolutely possible by taking suitable measures to ensure that extra material is

  
 <EMI ID = 5.1>

  
kerd. A greater problem, however, is the sealingly fitting of the second end portion within the open end of the barrel.

  
 <EMI ID = 6.1>

  
but moreover the transition between the two parts must be permanently completely gas and liquid tight.

  
The invention aims to provide a solution to this problem. The vessel according to the invention is characterized for this purpose in that the vessel body continues near the open end via a transition edge into a section with an enlarged diameter, within which a cylindrical circumferential edge of the second part is received closely fittingly, the circumferential edge of the second part being

  
 <EMI ID = 7.1>

  
position of the parts therebetween there is a place for a sealing ring, while the peripheral edge of the end part and

  
 <EMI ID = 8.1>

  
 <EMI ID = 9.1>

  
supersonically formed welding parts applied to these parts

  
t el, connections.

  
This achieves that, in the assembled state, a good seal is obtained between the edge and wall parts of the two parts, which are preferably situated against each other under bias, while the vessel is very strong. In addition, while retaining the sealing properties, the sealing ring may be more or less compressed before the spot welds are formed; the resulting variation in the net volume

  
 <EMI ID = 10.1>

  
forming the quarters and compressing the ring more or less until the vessel has the correct volume, after which the seals are formed.

  
Assembling the parts is facilitated when

  
 <EMI ID = 11.1>

  
and the outer wall of the cylindrical edge of the second part is slightly tapered.

  
Preferably, it is furthermore provided that of the first part designed as a cylindrical body, the outer diameter of the undivided end part is substantially equal to the inner diameter of the widened end part, such that the vessels can be stacked in a fitting manner.

  
The invention is elucidated with reference to the appended figure, which shows a half view - half longitudinal section of a vessel according to the invention.

  
In the figure, the vessel is indicated as a whole by the reference numeral 1. It consists of a, the barrel body formed

  
 <EMI ID = 12.1>

  
brought end part 3. Both parts are made by injection molding from plastic; the part 2 is cylindrical and is provided with the integrally formed roll edges 3a, 3b, 4a, 4b. The space between the rolled edges 3a, 3b resp. 4a, 4b can, as indicated by dotted lines, if desired, be filled with a plastic foam.

  
Inside the cylindrical top edge 5 of the barrel body 2, the diameter of which corresponds to that of the barrel body itself, is the integral, domed closure portion 6 with the bung hole 7 arranged in the usual manner.

  
 <EMI ID = 13.1>

  
whereby the rinse water used in cleaning the vessel can flow away.

  
The lower end of the barrel body 2 continues via a transition edge 11 into a cylindrical end rim 12 with an increased diameter relative to the barrel body 2. The cylindrical end edge 13 of the end part 3 fits within it. The two parts can be of slightly tapered design.

  
A plurality of superpersonally formed spot welds 15, 16 are arranged in two rows along the circumference of the cylindrical end edge 12 and the end edge 13; they provide an unshakable connection between these parts on a number of points. Such a supersonic spot weld is formed by pressing a pin-shaped tool, not shown, which is energized to vibrate against the outer surface of the rim 12 at a supersonic frequency. The heat generated melts the plastic material of the first portion 12 and then of the portion 13 in an area (indicated by the reference numeral 14) around the tool; the plastic of the two parts flows in and through each other and after the tool has been withdrawn and the material subsequently cooled and hardened, a perfect and particularly strong mutual connection is obtained.
