Abstract

In conventional hour-glasses, sand trickles from the top to the bottom. The new hour-glass is to make possible the opposite effect. The inverted hour-glass consists like the conventional hour-glass of a basic (hollow) body (1) with a constriction (3). It also has additional covers (2), filling with a liquid (4) and fine granular material (5) with a lower specific gravity than the liquid. Inverted hour-glasses are because of their surprise effect of particular interest as advertising and gift articles, souvenir articles and the like. <IMAGE>

Description

Die vorliegende Erfindung betrifft umgekehrte Sanduhren, d. h. Sanduhren, bei denen ein körniges Material nicht von oben nach unten fällt, sondern von unten nach oben aufsteigt.The present invention relates to inverted hourglasses d. H. Hourglasses where a granular material is not falls from the top down, but from the bottom up rises.

Sanduhren, insbesondere als Eier-Uhren oder als Zeit-Takt- Uhren zur mehr oder weniger groben zeitlichen Abgrenzung von Zeit-Einheiten beim Telefonieren sind jedermann bekannt. Ein in der Mitte eingeschnürter Hohlkörper (zumeist aus Glas) enthält Sand, der in einer bestimmten Zeit von einer Teilkammer in die andere rieselt.Hourglasses, especially as egg clocks or as time clocks Clocks for more or less rough delimitation Everyone knows time units when making calls. A hollow body constricted in the middle (mostly made of Glass) contains sand that is in a certain time from one Partial chamber trickles into the other.

Die Erfindung hat sich die Aufgabe gestellt, den Riesel­ vorgang umzukehren.The object of the invention is the trickle reverse process.

Der besondere Wert einer umgekehrten Sanduhr liegt im Ver­ blüffungseffekt und damit besonders zur Erzielung von Auf­ merksamkeit bei Werbe- und Geschenkartikeln, Andenken usw.The special value of an inverted hourglass lies in the ver bluffing effect and thus particularly to achieve opening attention to promotional and gift items, souvenirs, etc.

Zur Realisierung der Erfindung benötigt man eine Flüssig­ keit, feinteiliges Material mit geringerem spezifischen Gewicht als die Flüssigkeit und eine geschlossene Hohl­ kammer mit einer für Sanduhren typischen Einschnürung. Zweckmäßigerweise stellt man zunächst vorzugsweise per Kunst­ stoff-Spritzguß einen transparenten Grund-(Hohl)-Körper her mit einer Einschnürung in der Mitte und symmetrisch von ihr an den Enden der Teil-(Hohl)-Räume Öffnungen.A liquid is required to implement the invention speed, fine-particle material with lower specific Weight than the liquid and a closed hollow chamber with a constriction typical of hourglasses. It is advisable to start with art Fabric injection molding with a transparent basic (hollow) body a constriction in the middle and symmetrical from it the ends of the partial (hollow) spaces openings.

Eine Öffnung verschließt man vorzugsweise per Ultraschall- Schweißen mit einem vorzugsweise mitgespritzten Deckelteil. Dann füllt man das feinkörnige Material ein; danach die Flüssigkeit. Endlich verschließt man auch diese Öffnung - und zwar so, daß Lufteinschlüsse vermieden werden.An opening is preferably closed by ultrasound Welding with a cover part that is preferably injection molded. Then you fill in the fine-grained material; after that the  Liquid. Finally, you also close this opening - In such a way that air pockets are avoided.

Das feinkörnige Material siebt man vorher entsprechend wie bei herkömmlichen Sanduhren auf eine bestimmte Korngrö­ ßenverteilung aus. Das heißt, zu grobe und zu feine Anteile wer­ den eliminiert.The fine-grained material is screened accordingly beforehand as with conventional hourglasses to a certain grain size external distribution. That means, too coarse and too fine proportions who that eliminated.

Anstelle von Sand verwendet man hier wegen des erforderli­ chen niedrigeren spezifischen Gewichtes zweckmäßigerweise Partikel auf Basis Kunststoff, (Kunst)harz, wachsartiger Substanzen, kristallisierende organische Stoffe oder mikro­ verkapselte Gase, Flüssigkeiten oder Feststoffe. Mikrokapseln sind kugelig und daher besonders rieselfähig.Instead of sand one uses here because of the necessary Chen lower specific weight expediently Particles based on plastic, (art) resin, waxy Substances, crystallizing organic substances or micro encapsulated gases, liquids or solids. Microcapsules are spherical and therefore particularly free-flowing.

Bei den genannten Partikeln ist noch besonders die Eigen­ schaft hervorzuheben, daß sie prinzipiell in verschiedenen, auch kräftigen und leuchtenden Farben und auch fluoreszie­ rend eingefärbt werden können.In the case of the particles mentioned, there is still something special to emphasize that they are principally in different also strong and bright colors and also fluoresce can be colored.

Entsprechend kann auch die verwendete Flüssigkeit gestal­ tet sein.The liquid used can also be designed accordingly be.

Die Flüssigkeit sollte möglichst niedrigviskos sein und das feinkörnige Material weder auf- noch anlösen, noch anquellen, so daß es nicht zu Aggregationserscheinungen kommt.The liquid should be as low viscosity as possible and the fine-grained material neither dissolve nor dissolve, nor swell so that it does not cause aggregation is coming.

Die Zeichnung zeigt den prinzipiellen Aufbau einer umge­ kehrte Sanduhr.The drawing shows the basic structure of a vice returned hourglass.

Sie zeigt den Grundkörper 1 mit seinen Deckeln 2, der Ein­ schnürung 3 sowie der Flüssigkeit 4 und dem körnigen Ma­ terial 5.It shows the base body 1 with its lids 2 , the lacing 3 and the liquid 4 and the granular material 5 Ma.
