Abstract

A beverage vessel, for example a coffee can of an electrical coffee machine, comprises a receptacle (51) of glass or ceramic material and a two part handle including a mounting member (54) secured to the receptacle by a layer (56) of adhesive material, and a handgrip member (62) fastened to the mounting member by detent lugs (64, 66). The mounting member comprises a mounting surface which is permeated by ventilation channels (58), one end of each of which communicates with the adhesive material layer and the other end of each of which opens to ambient air. As a result, a good hardening of the adhesive material is obtaned even in the case of a single component adhesive. The adhesive material is connected to the mounting member (54) by anchoring portions (60) in the ventilation channels. In a further embodiment the channels are located in a mounting surface of the handle itself. <IMAGE>

Description

SPECIFICATION Beverage vessel The present invention relates to a beverage vessel, and has particular reference to a coffee can of an electrical coffee machine.

In the known cans of this kind, handles, for example of plastics material, are fastened to the receptacle by means of tension bands of steel. This has the disadvantage that the fastening band must occassionally be retightened and forms deposit locations for foreign matter.

Cans of that kind are also known, in which clasps formed from a resilient synthetic material on a handle partially encompass the receptacle and retain the receptacle therebetween. These grips are relatively expensive and the fastening clasps again form deposit locations for foreign matter. Tension bands and resilient fastening clasps also have the disadvantage that they are not particularly decorative and restrict the scope for shaping.

In addition, cans of glass with melted-on glass handles are known, but these are expensive and do not provide adequate thermal insulation.

If the handle is made from plastics material, there are advantages in cost and heat insulation. Suitable plastics materials are, for example, polypropylene and thermoplastic polyester, but adhesive substances, particularly silicone adhesives, do not have good adhesion to such plastics materials. This problem does not only occur with these plastics materials, but also to a greater or lesser extent with other plastics materials, as adhesive substances with good adhesion to glass or porcelain mostly adhere less well to plastics materials.

There is accordingly a need for a beverage vessel which has, with little production complication, a handle durably fastened to the receptacle.

According to the present invention there is provided a beverage vessel comprising a receptacle of vitreous material and a handle fastened to the receptacle, the handle comprising a mounting member secured to the receptacle by a layer of adhesive material and a handgrip member fastened to the mounting member.

Expediently, the mounting member comprises a fastening plate of plastics material glued to the receptacle, the handgrip portion being fastened to the plate by, for example detent connection means. The handgrip member can have a cover portion covering at least part of the mounting member. Expediently, the mounting member is provided with a plurality of ventilation passages extending therethrough to each communicate at one end with the layer of adhesive material and at the other end with the ambient atmosphere, the handgrip member being arranged to cover said other end of each passage.

In place of a fastening plate of plastics material, a fastening plate of glass or porcelain can be used, to which a handgrip member of plastics material is then fastened. This arrangement has the advantage that the receptacle can have a simple shaping and can easily be made by machine, the adhesive connection being made between two parts of like or similar material so that the adhesive material can be matched optimally to this material. The separate fastening plate of glass or procelain possesses substantially smaller dimensions than the glass receptacle and can thus be produced with relatively small tolerances, which facilitates the formation of the connection with the handgrip member.

Preferably, the handle comprises synthetic material, especially plastics material, and has a mounting surface which is permeated by ventilation channels, one end of each of which opens at the layer of adhesive material glueing the handle to the receptacle and the other end of each of which opens to the ambient air. As a result, it is possible to use an adhesive material having good adhesion to glass or porcelain, such as a one-component silicone adhesive, which for hardening requires the access of ambient air and moisture.

With this arrangement, there is no longer a need to use a tension band requiring retightening and forming deposit locations for foreign matter. In addition, high demands are not made on the material of the handle, for example in respect of elasticity and strength.

Expediently, the handle has a web extending between a grip opening thereof and a wall of the receptacle, wherein the mounting surface is formed at this web and the web has ventilation channels in the form of passages which, at a surface of the web remote from the wall of the receptacle, open to the ambient air. In this manner, there is obtained a large mounting surface and also a finger protection to prevent contact with the hot wall of the receptacle. The openings of the ventilation channels remote from the adhesive material layer can be concealed by a shield, wherein a ventilation space open to the ambient air is present between the shield and the openings of the ventilation channels.Thus, for example, a second web, which extends substantially parallel to the first web and the dimension of which in height and width approximately corresponds to those of the first web, can be formed between the grip opening of the handle and the first web, at a small spacing from the latter, to act as a shield on the handle. The handle is preferably an injectionmoulded part of plastics material. In this manner, the handle can be constructed as an inexpensive injection-moulded part with shield formed integrally thereon.

The handle can also possess a projection which rests on the upper rim of the receptacle and facilitates positioning of the handle during glueing. This projection can furthermore extend a short way into the receptacle, whereby the interengagement of the handle and receptacle is enhanced for the glueing operation and, in the case of a resilient hook-shaped projection, the handle is tightened against the jar in its upper region during the glueing operation.

The adhesive material layer providing the adhesive connection may be connected to the receptacle by adhesive effect and to the handle by "shape-locking" anchoring portions. This construction can also be employed in the case of adhesive substances, which adhere adequately to plastics material, to increase the reliability of the connection.

The amount of adhesive material used can be such that it issues from the free ends of the ventilation channels and forms, at the exit points, heads which provide a "shape-locking" anchoring. Anchoring also takes place when the adhesive material issuing from the free ends of the ventilation channels flows together to form a layer. The ventilation and hardening of the adhesive material layer between the receptacle and the handle is hardly impaired thereby. The ventilation channels can be provided, in direction of their free ends, with enlarged portions, which preferably have a substantially conical shape. in this case, the anchoring is effected in the ventilation channels.

Embodiments of the present invention will now be more particularly described by way of example and with reference to the accompanying drawings, in which: Figure 1 is a sectional elevation of part of a first beverage vessel embodying the invention; Figure 2 is a section, substantially along the line ll-ll of Fig. 1, wherein a layer of adhesive substance is omitted; and Figure 3 is a partly-sectioned elevation of a second beverage vessel embodying the invention.

Referring now to the drawings, in Figs. 1 and 2 there is shown a coffee can 1 which comprises a glass jar 2 to which a handle 4, which is particularly easy to remove from a mould as injection-moulded part of plastics material, is fastened by glueing. The handle 4 has a web 8, which is remote from the jar 2, extends obliquely downwards, forms a handgrip and is connected through an upper, upwardly open, U-shaped web 10 with an arm 1 5 extending substantially vertically along the wall of the jar 2.The arm 1 5 possesses a vertical web 16, extending along the glass jar, with a flat recess 30 receiving an adhesive substance layer 1 8. The web 1 6 is permeated by ventilation channels 20 in the region of the recess 30, wherein four channels per square centimetre of the adhesion surface are present. The channels 20 extend perpendicularly to the wall 14 of the jar 2 in the region of the adhesion surface. The recess 30 is surrounded by a flat gutter 32 and separated from this by a narrow web 34. The gutter 32 serves to receive any adhesive substance issuing laterally from the recess 30 so that adhesive substance cannot issue laterally between the handle 4 and the wall 14 of the jar and disturb the decorative appearance.The arm 14 possesses a slightly inclined web 24, which lies at a spacing from the vertical web 16, conceals the vertical web 1 4 and together with this forms a downwardly closed blind hole 26 with withdrawal ramps for the injection-moulding tool. The handle 4, which as a whole is bowl-shaped, can be closed off upwardly and at the side remote from the jar by a cover part. Alternatively, a closure element 36, shown in broken lines in Fig. 1, can close off the hole 26 in the vertical arm 15, the closure either being permeable to air or else mounted only after complete hardening of the adhesive substance layer.

The quantity of the adhesive substance forming the layer 1 8 is such that it completely fills the ventilation channels 20 and issues at the free end thereof so as to form a thickened head 38. The heads 38 represent a "shapedlocking" anchoring of the adhesive substance layer at the web 16, which has the ffect that an adequate connection is provided even if the adhesion of the adhesive substance to the plastics material of the web 1 6 is broken.

In the embodiment shown in Fig. 3, a glass jar 51 possesses a vertical side wall 52, to which a fastening plate 54 is glued by means of a layer 56 of a silicone adhesive substance.

The plate 54 has a large number of ventilation channels 58, which permeate it horizontally and which each enlarge conicaliy towards their free end away from the adhesive substance layer 56. The quantity of the adhesive substance is such that the ventilation channels 58 are largely filled, the adhesive substance forming a conical anchoring head 60 in each ventilation channel. A handle portion 62 of plastics material is fastened to the upper and lower ends of the fastening plate by detent lugs 64 and 66. The handle portion 62 has a cover web 68, which extends parallel to the plate 54 and conceals the openings of the channels 58.

In modification of the embodiment according to Fig. 3, in place of the fastening plate 54 of plastics material there can be used a fastening plate of glass which otherwise has the same shape as the plate 54. The handle portion consists of plastics material just as before and is connected by detent means with the glass fastening plate.

The beverage vessel of claims 1 and 2 is also described in the specification of United Kingdom patent application No. 81 38 077.
