Description

DRINKING VESSEL ACCESSORY AND SYSTEM FOR MONITORING AND MANAGEMENT

OF INTAKE OF LIQUIDS

TECHNICAL FIELD

The present invention relates generally to a drinking vessel accessory and a system comprising a drinking vessel, a drinking vessel accessory and a remote server or software backend, where the drinking vessel accessory is configured to monitor the intake of liquid for a person and, if neccesary, to motivate the person to drink more. More specifically, the invention relates to a drinking vessel accessory that is configured to wirelessly send and receive data to a software backend or remote server that forms part of the system and to provide data that are relevant in connection with a person’s use of the drinking vessel and drinking vessel accessory.

BACKGROUND OF INVENTION

Poor hydration can increase the risk of disease (falls and accidents, bowel, metabolic and kidney diseases), disability (cognitive function, physical performance and headache) and ultimately death.

According to the EFSA (European Food Safety Authority), experts recommend an intake of 2,5 litre of water for men and 2,0 litres for women. With age, the ability to feel thirst and thus remember to drink liquid is reduced. A British cohort study of the Dehydration and clinical outcome in hospitalized older adults by A.M. El-Sharkawy et al from 2016 states that dehydration was noted in 8.9% of all patients and was the primary cause of admission in 0.6% of the cases. It is therefore important to make a product that elderly people will use.

Recent figures from Eurostat (2016) shows that 19,2% of the EU-28 population are over 65 years old and 32,1% of them live alone so it is very important to be able to motivate seniors on a distance to drink liquids in order not to get dehydrated. There is therefore good reason and need for a system that helps people to stay hydrated.

Mainly the sports equipment industry has driven the development of “intelligent drinking vessels” fuelled by the growth of health awareness and people looking for smart solutions. PR Newswire has forecasted a worldwide market of US$ 10,4 billion by 2025 for the Smart Bottle market. There are multitudes of bottles available that, using different measurement technologies, monitors the intake of fluids, and consolidate and visualize data via an app. Some brands on the market include Thermos, Trago, LifeFuels, HidrateSpark, HydraCoach, H20pal, lcewater and Equa. The trend has spread to “smart cups” which are more suitable for use in an office environment but with the same functionality as the bottles. Some brands on the market include 0nlyH20, Lihoo, Hoof, Ember, Gynne-Cup and MyVessyl.

Two different “Smart glasses” for beer (from Glassify and Rastal) use the same principle: A small near-field sensor attaches to the stem and foot of the glass. The sensor works a simple counter so that it is possible to see how may time it has been in the proximity of beer tap (and thus counting the refills).

Further, there are scales available in the shape of a coaster (Cupad), an alarm clock with accelerometer (Ulla) which alerts the user with a buzz and light in case of inactivity and the smart lid (Water-io) makes existing bottles upgradable. Other brands such as TheHug and Droplet attaches to an existing bottle.

Especially, although not exclusively, within health care systems and institutions, there is a need for a drinking vessel system that can ensure that a user, for instance an elderly or handicapped person living at home or i a nursing home or a patient at a hospital, actually obtains the required amount of liquid for instance per day, whitout day care personel or others necessarily having physically to monitor the user’s intake of liquid. In a large nursing home or hospital, manual supervision of the user’s liquid intake requires much work and places a large work load and administration on personel. Also, home care service organizations serving large geographical areas would benefit from a system that obviates the need of actual physical supervision of for instance elderly or handicapped persons dayly intake of liquid.

DETAILED DESCRIPTION OF THE INVENTION

With reference to figure 1 there is shown a drinking vessel 1 attached to drinking vessel accessory 2. here and in the following detailed description termed ”a puck. The puck has a display 3 where relevant information such as drinking data, graphics, messages, imagines, video and animation can be shown. The puck has a bottom part 4 that can move independently in the vertical direction z of the puck 2. The puck 2 and the bottom part 4 of the puck 2 is connected via a weight cell (not shown). The puck 2 is equipped with a magnetic USB port 5 through which data and electrical power can be transferred into the puck and through which data can be transferred out of the puck. The puck 2 is provided with grooves 6 allowing a loudspeaker positioned inside the puck 2 to play as efficiently and with as good a sound quality as possible while still providing mechanical integrity and protection. Fig 1 A shows the drinking vessel 1 and the puck 2 seen from the front where the display 3 shows an example of drinking data, here the actual content of the drinking vessel 1. Fig 1 B shows the drinking vessel 1 and the puck 2 seen from an angle above. Fig 1 B shows the drinking vessel 1 and the puck 2 seen from an angle below. Fig 1 D shows the drinking vessel 1 and the puck 2 seen from the behind.

With reference to figure 2 there is shown the drinking vessel and the puck as separate parts. Fig 2A shows the drinking vessel 1 under which a ferromagnetic disc 7 with a centrical circular hole is attached. Fig 2B shows the puck 2 with a top cover 8 which has a plateau 9 with a cylindrical form factor where the diameter of the plateau 9 is slightly smaller than the cylindrical plateau and where the height of the plateau 9 is smallerthan the thickness of the ferromagnetic disc 7 so that the two parts fit into each other. Fig 2C shows the puck 2 as seen from the side.

With reference to figure 3 there is shown some interior of details the puck 2 showing a gasket 10. Fig 3A shows the through openings 11 where a weight cell (not shown in the figure) is attached to the bottom part 4 of the puck 2 so that the puck 2 and the bottom part 4of the puck 2 within the deformation range of the weight cell can move freely with respect to each other. The gasket 10 seals the gap between the two parts which (when the two parts move) creates a frictional force. Fig. 3B shows the lower outer part of the puck bottom 4 and the lower part of the puck 2 and the screws 12 attaching the weight cell to the lower part of the puck 4. Fig. 3C shows a cross section of the puck 2 illustrating the position of the gasket 10 connected to the bottom of the puck 2 and touching the inner perimeter of the puck 2, thereby creating a seal.

Some embodiments of the puck according to the invention are provided with an alarm, which may be aither audio or visual or a combination of these. The alarm can also in some embodiments be transmitted to a remote server for instance bia wireless connection to the internet. These embodiamens are also provided with means configured to trigger the alarm. Thus, with reference to figure 4 there is shown two ways of triggering alarms. Fig 4A shows the actual consumed amount of liquid 13 measured by the puck 2 as a function of the time of the day. In this case the user starts drinking of the cup between 5 and 6 in the morning. The curve 14 shows a first alarm curve that triggers a given alarm event if the curve 13 drops below the curve 14. Curve 15 is an even more severe alarm curve that, if crossed by curve 13, will trigger an alarm that indicates that an even more critical situation is existing, where the user has drunk much less liquid during this day than actually required. Curve 14 and curve 15 can be adjusted to fit individual needs. Fig 4B shows an alternative way of controlling the triggering of alarms. If no liquid has been drunk for a given (individually adjustable) period of time, an alarm will be triggered. No alarm will be triggered during the alarm free periods. Thus, during period 16, i.e. during the night and the early morning no alarm is triggered. During the period from 10.00 in the morning to 15.00 in the afternoon, the user is actually drinking liquid from the drinking vessel but inlu until 13.00 in the afternoon, after which time he stops drinking. An alarm is elicited around 13.00 indcation that the may be a problim with the user not drinking enough liquid. At 15.00 he starts drinking again and no alarm is thus elicited in the period from 15.00 to 17.00 in the afternoon. An alarm may again be elicited somtimes during the period 17.00 to 20.00 depending on the actual setting of alarm triggering means. Finally, after 20.00 in the evening, the user is not expected to drink any liquid, or only a limited amount of liquid, and no alarm is elicited during the period from 20.00 to 24.00.

The actual amount of liquid still present in the drinking vessel can in some embodiments be determined by means of the weight cell mounted at the bottom part 4 of the puck 2, but other means for determining the amount of liguid present in the drinking vessel may alternatively be used.

With reference to figure 5 there is shown examples of different drinking vessels (that may be ofdifferent material) attached to the same puck 2. Fig 5A shows a drinking vessel 1 in the shape of a bottle made of borosilicate glass attached to a puck 2. Fig 5B shows a drinking vessel 1 in the shape of a ceramic mug attached to a puck 2. Fig 5C shows a drinking vessel 1 in the shape of a stemmed crystal glass attached to a puck 2. As the different drinking vessels are unlikely to be of the same weight, the weight cell in the puck 2 can either be provided with recalibration means or software installed in the puck 2 will have one pre-calibrated setting for each different drinking vessel.

With reference to figure 6 there is shown different embodiments of the puck 2 provided with with different functionalities. Fig 6A shows a puck 2 where the display 3 is replaced with an embedded mini projector 17 making it possible to, depending on the position of the projector, to project data onto nearby surfaces such as a desk or a wall. Fig 6B shows a system where the USB plug 5 is replaced with an embedded inductive coil (not visible in the figure) so that the puck 2 can be charged via an inductive charger 19. Fig 6C shows a puck 2 with a window 20 that goes all the way through the puck 2 enabling an embedded miniature spectroscope, for instance but not limited to Raman spectroscopy, to send and receive light signals through the puck and through the drinking vessel and into the liquid and by analysing the signals thus being able to determine the type of liquid inside the drinking vessel.

With reference to figure 7 there is shown different ways to fasten a ferromagnetic disc 7 to a drinking vessel 1. Fig 7A shows a drinking vessel 1 where the ferromagnetic disk 7 has been attached by means of an adhesive where the adhesive can accommodate the potential different thermal expansion coefficients of the materials used for the drinking vessel 1 and the ferromagnetic disc 7. Fig 7B shows an alternative solution where the ferromagnetic disc 1 is placed in a muff 21 made of an elastic material such as but not limited to silicone, neoprene, TPE or natural rubber, and where the dimensions, stiffness and friction of the muff 21 makes it possible to place it around the bottom of the drinking vessel 1 . Fig 7C shows a version of the muff where a metal disc 23 is completely embedded by the flexible material of the muff 22 and where the muff 22 is designed in such a way so that the disc 23 does not need any centred hole.

It should be noted that while the embodiments of a drinking vessel shown in figure 7 comprises a ferromagnetic disk or similar means and the puck consequently comprises corresponding magnetic (either permanent or electromagnitic) means, the opposite could also be sued in the invention, i.e. magnetic means in the drinking vessel and corresponding ferromagnetic material in the puck, and that this alternative would also fall within the scope of protection of the invention.

With reference to figure 8 there is shown an embodiment of the invention comprising a mechanical attachement between the drinking vessel and the drinking vessel accessory. Figure 8A shows a perspective view of a first embodiment comprising a releasable mechanical attachment between the drinking vessel 1 and the drinking vessel accessory 2 configured as a bayonet connection having a number of spaced apart radially extending protrusions 27 provided at a bottom portion 26 of the drinking vessel 1 . The bottom portion 26 has a diameter that is reduced compared to the rest of the drinking vessel 1 such that the bottom portion 26 can fit into a corresponding top portion 28 on the drinking vessel accessory 2. In this embodiment, the mechanical attachment is configured as a bayonet connection, in which the protrusions 27 can be brought in engagement with corresponding recesses 29 provided in the top portion 28 of the drinking vessel accessory 2.

In figure 8B there is shown an embodiment basically similar to that of the figure 8A but comprising a frictional disc or pad 30 introduced between the the bottom surface 26’ (not visible in figure 8) and the corresponding top surface 28’ of the top portion 28 of the drinking vessel accessory 1. This disc or pad ensures that the drinking vessel 1 does not become unintentionally released from the attachement to the drinking vessel accessory 2 for instance during use of the invention.
