Description

AUE R-GLAS WERK E GMBH, Bad Gandersheim / Harz ---------- Glass vessel with a handle, in particular for kitchen machines.

The invention relates to a glass vessel with a handle.

In particular, it relates to a beaker for so-called blenders, made of a temperature-resistant glass, especially borosilicate glass, is made.

It is generally desirable to use in the household, especially at Kitchen machines, used glass vessels with a handle to do so To make it easier to touch and to prevent the introduction of hot liquids, that the glass is touched by the heated vessel wall.

It is known to have such glass vessels with a handle that can be reached through to be provided, dr after the manufacture of the vessel on the vessel wall is melted. This method has the disadvantage that the labor during manufacture is very large and easily stresses at the melt-down points occur that lead to fractures under mechanical or thermal stress can. Particular difficulties arise in the manufacture of such glass vessels in the pressing process, the use of which is always desired in the production of larger quantities will. It has been shown in practice that when pressing at the same time Handle and vessel with the known means and procedures, usually at the transition points internal tensions or even cracks result from the vessel wall to the handle, which if mechanical and thermal stresses occur, it can be destroyed of the vessel. It has now been found that when using the pressing process Have flawless glass vessels produced, even in large numbers, if the fusion surface of the seamlessly pressed Handle inside of the handle and outside of the vessel wall.

In this case there is a tension-free transition of the glass flow from the vessel wall to the handle, during which the occurrence of glacial tension is the cause The fusion area lies outside the transition area between the wall and the handle. The illustration shows an example of such a glass vessel and a mold for their manufacture is shown.

The mold for producing the glass vessel consists of an outer molded body (1), which defines the external shape of the vessel to be produced. An opening (2) is provided in a side wall of the body (1) which corresponds to the desired shape of the handle of the vessel. The soft glass mass (3) is introduced in this form (1). The next step is to insert a punch (4) from above, the outer shape of which corresponds to the inner shape of the vessel to be manufactured. Through the stamp, the glass mass is pressed into the space between parts (1) and (4), while at the same time a free flow occurs in the direction of the arrow (5) in the cavity provided for the handle. The lower and the upper one Step opening (6) or (7) and the shape of the handle are so dimensioned so that the gas flow flowing upwards in the direction of arrow (8) reaches the opening (7) earlier than the glass flow flowing in the direction of arrow (5) the fusion surface (9) lies outside the vessel wall inside the handle itself. The tensions that may arise with each fusing process can no longer occur in the transition zone between the wall and the handle, since it was a closed glass flow while the Vereohmelzfläohe continues outside in an area with an approximately constant cross-section. Ee has become shows that with the method described in one work- bettagang Make gong vessels with grippable lugs with which, even with large quantities, only one small number of external parts can be determined. The method described is particularly valuable in the manufacture -) Positioning of vessels made from melting at high temperatures temperature change resistant borosilicate glasses, as their working is much more difficult than working at lower Temperature melting soda-lime glasses. 4, I. The finished slat is removed from the mold on both game wines as a result, the outer molded body 1 was in two parts is formed, the separation surface in the plane of the handle. lies. After completion of the pre-process, such a Separated the shape and the finished vessel from the molded parts. I. val I, \ {I f The process described is not just for manufacturing suitable for Beoher glasses, but also, for example, for bowls with 1 "or clamped handles.

Claims (2)

Claims; 1. Glaagefaea with handle, especially for kitchen machines, daduroh characterized in that the fusion surface of the seamlessly pressed-on handle lies within the handle outside the vessel wall. 2. Glass vessel according to claim 1, characterized. that It is made of temperature-resistant glass, preferably made of Boroailikat glass.
