Embodiment Construction

Referring initially to FIGS. 1 to 9 of the drawings, there is shown a drinking device embodying the invention, which is in the form of a trainer cup 10 for infants and comprises a plastic body 100 for containing liquid and a plastic lid 200. The cup body 100 includes an open upper end 110 having a circular rim 112, over which the lid 200 is pressed for sealingly closing the cup end 110. The lid 200 has a circular body 210 which comprises a depending rim 212 for externally engaging the cup rim 112, an air inlet hole 214 at the centre, and an upstanding spout 220 on one side.

The spout 220 has an apex 222 with an outlet hole 224 and includes an internal integral member or bar 230 extending, downwards from the apex 222, at a position close to the lid rim 212. The bar 230 has an upper end (half) 232 which has a hollow rectangular cross-section and includes a co-extending partition 234. The partition 234 has a part-circular cross-section and defines a duct 236 extending downwards from the...

Abstract

A drinking device including a body having an open end and for containing a liquid, and a lid for sealingly closing the open end of the body. The lid has an outlet incorporating a first one-way valve for dispensing liquid from the body upon the application of suction at the outlet and an inlet incorporating a second one-way valve for air intake to automatically balance the internal pressure within the body with external pressure outside the body while liquid is being dispensed. The first valve includes a chamber having a resiliently deformable wall including a hole in communication with the outlet. The hole is normally closed by being pressed against an internal surface of the body by the resilience of the wall and is openable upon the application of suction.

Description

The present invention relates to a drinking device, and particularly, but not exclusively, to a trainer cup for infants, which is leak-proof.BACKGROUND OF THE INVENTIONLeak-proof drinking devices are, of course, generally known, particularly for infants, which usually have a body and a lid closing the body. In one of the known constructions, for example as disclosed in UK Patent No. 2266045, the lid has an outlet for dispensing liquid and an air inlet for pressure balance, both of which are provided with respective one-way valves to protect against leakage.Liquid is to be extracted from inside the body through suction applied to the outlet. While the valve of the outlet should be closed reasonably tightly normally, it has to be opened relatively easily to facilitate drinking. None of the known devices is found to be satisfactory in this regard.The invention seeks to mitigate or at least alleviate such a problem by providing an improved drinking device.SUMMARY OF THE INVENTIONAccordi...
