Abstract
A cup for a patient suffering from dysphagia comprises a base upon which the cup is capable of standing when on a level surface and a leading wall extending from the base. The leading wall has a first portion that is substantially planar or concave when viewed from outside the cup, the first portion being at an angle of at least 100 degrees relative to the base. The cup also comprises a trailing wall opposite the leading wall, wherein the trailing wall extends from the base to the lip of the cup; and side walls extending between the leading and trailing walls, the side walls being convex when viewed from outside of the cup. The lip of the cup is upwardly inclined relative to the base in the direction of the trailing wall to the leading wall. The cup allows a patient suffering from dysphagia to drink without having to unduly tip back his or her head.

The following Description is not to be regarded as limiting the scope of the preceding Summary of the Invention in any way.
DESCRIPTION OF EMBODIMENTS
[0100] Embodiments of the invention will now be described with reference to
[0101]
[0102] As shown in
[0103] The lip 30 of the leading wall (which may form part of the third portion 26) is arcuate, and the first portion 22 is concave (when viewed from outside the cup) to provide a depression to accommodate a patient's thumb. The first portion 22 is about 3.7 cm wide and is of substantially constant width along its length. The second portion 24 narrows in width towards the lip 30 and is generally arch-shaped.
[0104] The first portion 22 of the leading wall includes nine longitudinally extending ridges 32, and each ridge is about 4 mm apart and about 2 mm thick. The longitudinally extending ridges 32 may assist a patient to grip the cup 1 and may also assist in destacking the cups 1 (when two or more cups 1 are nested together).
[0105] The cup 1 includes a trailing wall 40 extending from the base 10 opposite to the leading wall 20. As illustrated in
[0106] The lip 50 of the trailing wall (which may form part of the third portion 46) is arcuate, and the first portion 42 is concave (when viewed from outside the cup) to accommodate a patient's fingers when drinking from the cup 1. The first portion 42 is about 2.3 cm wide and is of substantially constant width along its length. The second portion 24 narrows in width towards the lip 30 and is generally arch-shaped. The distance between the top of the first portion of the leading and trailing walls 22, 42 is about 57 mm. This distance may advantageously assist a patient to grip the cup 1.
[0107] The first portion 42 of the trailing wall includes five longitudinally extending ridges 52, and each ridge is about 4 mm apart and about 2 mm thick. The longitudinally extending ridges 52 may assist a patient to grip the cup 1 and may also assist in destacking the cups 1 (when two or more cups 1 are nested together).
[0108] The cup 1 includes a plane of symmetry bisecting the leading and trailing walls 20, 40. The cup 1 includes two side walls 60, which each extend between the leading and trailing walls 20, 40. At least 80% of the length of each side wall 60 is at an angle of about 96 degrees relative to the base 10. Each side wall 60 includes five longitudinally extending ridges 62. Each ridge 62 is about 2 mm thick and about 5 mm apart.
[0109] The lip 70 of the cup is ovoid to accommodate a patient's nose when drinking from the cup 1. The distance at the lip 70 between the inside of the leading and trailing walls 20, 40 (i.e. along a plane bisecting the leading and trailing walls 20, 40) is about 7.7 cm, and the distance between the outside of the leading and trailing walls 20, 40 is about 8.6 cm. The distance between the inside of the two side walls 60 (i.e. along a plane bisecting the two side walls 60) is about 6.7 cm, and the distance between the outside of the two side walls 60 is about 7.8 cm. The inner circumference of the lip 70 is about 230 mm. The outer circumference of the lip 70 is about 260 mm. The lip 70 is angled at about a 4 degree upward incline relative to the base from the trailing wall 40 to the leading wall 20. This also reduces the need for a patient to tilt his or her head backwards during drinking (i.e. lifting the chin), thereby assisting in keeping the laryngeal inlet closed during drinking.
[0110] The lip 70 includes a flange 72 (the lip 70 is formed from the leading and trailing walls 20, 40 and the side walls 60). The flange 72 is about 5 mm wide and is adapted for adhesion of a seal to seal the contents of the cup 1. The cup includes a substantially cylindrical headspace 80 defined by the walls 20, 40, 60 of the cup 1 (including the third portions 26, 46 of the leading and trailing walls 20, 40). The usable volume of the cup (below the headspace 80) is about 150 mL. The total volume (including the headspace 80) is about 200 mL.
[0111] The walls of the cup 1 are angled so as to provide substantially no residual volume of fluid at the bottom of the cup 1 after drinking from the cup 1. The cup is stackable, so that one cup 1 will substantially fit within or nest within a second cup 1. The walls of the cup 1 are of substantially the same thickness. The cup may be made from a laminate of polypropylene and an ethylene vinyl alcohol (EVOH) copolymer.
[0112]
[0113] In preferred embodiments of the present invention, the cup includes an angled lower portion of the leading wall and an oval-shaped opening at the top of the cup. The angle of the lower portion of the leading wall, in combination with the oval-shaped opening at the top of the cup, means that the cup can be emptied without the person drinking from the cup having to tilt their head backwards to any great extent. The angle of the lower portion of the leading wall facilitates emptying of the cup without requiring that the cup be tilted to as much of an angle as that required for cups without such an angle in the leading wall. Further, the oval-shaped opening at the top of the cup provides clearance around the nose of the user when the cup is tilted, thereby further obviating the need for the user to tilt their head backwards during drinking. This beneficial effect is even further enhanced in embodiments where the top of the cup angles downwardly from the leading edge to the trailing edge of the top of the cup. In these embodiments, the trailing edge of the top of the cup is lower than the leading edge of the top of the cup and therefore the cup may be tilted to a greater angle before the trailing edge of the top of the cup comes into close proximity with the nose or face of the user. Cups of preferred embodiments of the present invention may contain volumes of fluid that are larger than other cups that are of small size to avoid coming into contact with the nose of the user during drinking. This also enhances convenience for the user in that it is not necessary to fill the cup multiple times to enable a reasonable volume of fluid to be drunk.
