Abstract

A drinking glass composed of a glass bowl (1), a base and a stem (3), the stem (3) being fixed to the bowl (1) by a joining piece (4); the glass bowl (1) being designed with locking profiles (7 and 8) consisting of a groove (7) and a bead (8) located at the bottom (5) and lower side (6) of the bowl (1) which interlock with the corresponding locking profiles (9 and 10) of the joining piece (4) to create an impermanent, i.e. dismantable lock between the glass bowl (1) and the joining piece (4), and the joining piece (4) and the stem (3), as well as the stem (3) and the base are impermanently interlocked. The stem, the base and the joining piece are of plastics material. <IMAGE>

Description

SPECIFICATION A drinking glass The subject of the invention is a drinking glass composed of a glass bowl, a base and a stem, where the material of the base and stem is different from that of the bowl.

Such drinking glasses are well-known. One type is the so-called "rummer", a frequent characteristic of which is that the glass body of the stem and base is a different colour from that of the bowl. Another type are glasses consisting of a bowl and a stem mounted on a loose base.

In the automatic production of drinking glasses the most demanding and therefore relatively costly technical operation is the fixing of the stem onto the bowl. Very few glassworks have solved this problem satisfactorily, and despite automation of the process, it has not been possible to bring down the cost of this operation to a reasonable level.

In addition to the technical and financial obstacles mentioned above, another disadvantage of the socalled "rummers" is that the colour of the different parts of the glass is not resistant to for example treatment in automatic dishwashers, and, furthermore, that such glasses are fragile and break easily during cleaning and transport. For glasses consisting of a bowl and a stem mounted on a loose base remain the technical and financial obstacles of attaching the stem and the increased risk of breakage in the joining area.

The purpose of the present invention is to design a drinking glass of the type described in the first paragraph which presentsfewtechnical and financial difficulties and, hereunder, is easy to assemble, handle and clean and has low risk of cranking or breaking.

This purpose is met by the following design: The stem together with a piece connecting the stem to the glass bowl are made from a material with different physical properties from that of the bowl. A locking profile consisting of a groove and a bead is located at the bottom and lower part of the side of the bowl. This is designed to interlock with a corresponding locking profile in the joining piece thereby creating an impermanent lockwhich permits dismantling. The joining piece and the stem, as well as the stem and the base, interlock in such a way that they may be dismantled if required.

A preferred version of the design specifies the use of primarily a plastics material for the joining piece, the stem and the base. The combination of glass and plastics material fully eliminates the technical and financial difficulties encountered when fixing glass stems onto glass bowls. The present design whereby the bowl and the stem are assembled by means of interlocking profiles offers a reliable and very efficient assembly method suitable for mechanized as well as simple manual assembly.

Manuai assembly does not require skilled labour and may be a suitable production for workshops elm plying handicapped people. The advantage of designing the joining piece, stem and base with impermanent locks is, apart from easy assembly, that the individual parts may be used for different types of glasses so that only a limited range of stock needs to be held of these items. Another advantage is simplified packing, as the glass bowls may be packed separately, and the stems and bases, which are very light and robust, may be packed in simple non-shock-absorbing packing material. The cost of transport, packing and insurance will consequently be lowered, and this will affect the price advantageously.

In a favoured version of the invented design the locking profile of the bowl consists primarily of a groove located in the lower side of the bowl and an adjacent bead protruding along the edge of the bowl between its side and bottom, and the locking profile of the joining piece primarily of a bead protruding along and parallel with the edge of the joining piece, and a groove adjacent to it. When the glass is assembled, the bead on the bowl is fitted into the groove in the joining piece, and the bead on the joining piece into the groove in the bowl.

In a special version of the design the length of the stem is so much reduced that the joining piece and the base can be combined to a single component.

The resulting design is a drinking glass with a base.

When applied to an ordinary tumbler type drinking glass with rectangular cross-section, this design produces a glass which is more stable and cheaper to manufacture than the corresponding tumbler.

Below follows a survey of the invented design with references to the attached sketch.

Glass bowl 1 with joining piece 4 and stem 3 impermanently interlocked with base 2. The interlocking profiles, namely the beads 8 and 10, and the grooves 7 and 9 are designed to ensure a firm grip during use and easy dismantling for cleaning. For this purpose the curvatures of the bead profiles 8 and 10 and the groove profiles 7 and 9 are designed with relatively large and varied radii.

A further advantage of the design is that the user may replace the glass bowl 1 if this breaks.

The bowl 1, joining piece 4, stem 3 and base 2 may be assembled by man-operated machines, or manually by unskilled labour. As previously mentioned, this permits assembly by handicapped persons' workshops where only a limited range of stock will be needed, as the different types of glasses, i.e. claret, champagne and white wine glasses, etc. can be mounted with the same joining piece 4, stem 3 and base 2.
