UCB is the upgraded version of the conventional hot-water bottle. Ergonomically shaped (including massage riffles) and designed to keep you warm and cosy during your daily routines – whether it’s at the office, during outdoor activities or while having a relaxing rest at home. 
In combination with our comfy, removable belt, our hot-water bottle can be worn in multiple ways: around your neck and shoulders, around your upper or lower back or around your belly. 

Studies have proven that heat in general has a similar effect to a painkiller, effectively “deactivating” pain at a molecular level. In this way, completely naturally and without any chemicals, heat shuts down the regular pain response and helps with issues such as menstrual pain, neck tension and abdominal cramps, and even diseases such as endometriosis or Crohn’s disease. However, hot-water bottles by themself do not ease pain. UCB do not claim the capability of a medical device. In case of doubt, consult your doctor or pharmacist.

Yes. The fact that heat relieves abdominal pain, such as colic or menstrual pain, has been scientifically proven by a UCL (University College London) scientists.
Dr Brian King, of the UCL Department of Physiology, led the research that found the molecular basis for the long-standing theory that heat. provides relief from internal pains.
Dr King said: “The pain of colic, cystitis and period pain is caused by a temporary reduction in blood flow to or over-distension of hollow organs such as the bowel or uterus, causing local tissue damage and activating pain receptors. If heat over 40 degrees Celsius is applied to near to where internal pain is felt, it switches on heat receptors located at the site of injury. These heat receptors in turn block the effect of chemical messengers that cause pain to be detected by the body.

Please do not fill your Urban Cross Botte from a tap or other domestic water system as this can prematurely degrade the product. 
After usage, please allow your bottle to air dry completely with the lid open. This will help to avoid unwanted moisture build up in your bottle and around the seal.  
Store your bottle with the lid off and keep in a cool, dry and dark place.
Avoid contact with hot surfaces, oil, grease and direct sunlight pointed and sharp objects. Do not allow anything to rest on the bottle.
Since the bottle is manufactured out of natural rubber, without any additional, chemical protective layer, it is possible that your bottle gets a patina after some time of usage. If this bothers you, you can water the outside of the bottle with hot water, with the goal to visibly reduce these marks again. Note: Hot water can cause burns. Please execute this procedure with caution and avoid direct hot water contact to the skin. Please note that we decline any liability to it.
To ensure that you are always using a bottle which is in good condition and safe it is advisable to replace your rubber bottle every 2 years.

UCB holds 800ml. Nevertheless its is recommend to fill the bottle only max 2/3 or less to avoid burns. 
Don’t forget: Do not use boiling water, even hot tap water can scald.
Hold the hot-water bottle by its neck, while carefully filling the bottle to a maximum of 2/3 to prevent any water from splashing back. Hot water bottles should always be filled by a responsible adult.

Hot water bottles can be dangerous & cause burns if they are not cared for or used in the proper way. Please read our instruction for filling, using and caring for your hot water bottle displayed here
When filling your hot water bottle, do not use boiling water. 
While filling hold the bottle by the neck in an upright position and fill slowly to avoid water splashing back. Only ever fill your bottle to a maximum of two-thirds capacity. Always expel air from the bottle by lowering it carefully onto a flat surface until the water appears at the opening.
Screw the stopper tight to ensure there is no leakage. Check your bottle thoroughly, including the stopper when using for the first time. Thereafter, check it regularly for wear, leaks and damages.

This recommendation is valid for all hot-water bottles, not just UCB. This recommendation is for your protection as hot water can cause burns.
Doctors recommend 40-50 degrees as the ideal water temperature. Always cover your bottle with a adequate cover, like a sweatshirt.
Do not use if you are concerned.

Check your bottle thoroughly, including the stopper when using for the first time. Thereafter, check it regularly for wear, leaks and damages.

The aim of the Fair Rubber Association is to contribute an improvement of the working and living conditions of the producers and farmers in the growing regions as well as to promote the environmentally friendly production of natural rubber, as chemical free production first. 
We are happy and proud that our re-shaped hot-water bottle fulfills the criteria of fair trade in natural rubber. Read more about the criteria here:

Natural rubber is produced by the rubber tree (Hevea brasiliensis). In order to collect the latex milk from tree, an incision is made in the bark of the rubber tree – which is called ‘tapping’. Depending on the use, following the tapping stage the latex milk is processed in different ways. About 70 per cent of natural latex is used for tires. Other products made of natural rubber are e.g. mattresses, condoms, shoe soles, hot water bottles, balloons, rubber boots and seal rings. Natural rubber can be substituted by synthetic rubber for some applications. Synthetic rubber is made from petroleum (i.e. fossil fuel). In many products – such as car tires – natural as well as synthetic rubber is used. More detailed information about rubber, you can find here or in this study by Aidenvironment.

It is not recommended to fill a Hot-Water Bottle with tap water because tap water qualities can vary significantly depending on the region. For example, tap water may contain minerals such as calcium or have a high level of hardness, which can potentially damage the rubber material of the Hot-Water Bottle. Additionally, tap water may contain impurities or bacteria that could affect the hygiene and safety of the Hot-Water Bottle. Using tap water can also increase the risk of burns due to its potential to reach higher temperatures when heated.

The production of natural rubber can be characterised with ecological and in some cases severe social problems. Low world market prices for natural rubber make it more and more difficult for latex producers to make a living from tapping rubber. Furthermore, studies document cases of extremely poor working conditions. Typical problems include inadequate safety standards, inappropriate use of toxic chemicals, discrimination, excessive working hours and child labour. Agro chemicals used in the production of natural rubber are less controversial with regard to any residue in the final rubber products. Far more important is that their use threatens the health and well being of the people involved in the production and processing of the natural rubber. More information about sustainability problems and solutions in the rubber sector, you can find here.

The low market price paid for rubber and bad working conditions, make it very difficult for the tappers, plantation workers and small farmers to support themselves and their families with their own labour. This is where the Fair Rubber Association wants to help. Paying a Fair Trade premium to the primary producers ensures to the extent possible that even during periods of depressed world market prices, the costs of production are covered and the suppliers have a surplus. Crucially this allows them to improve their working and living conditions. The decision as to how they would spend the Fair Trade premium, of course, remains with the primary producers.
The Fair Rubber criteria are closely based on the relevant criteria of Fairtrade Labeling Organizations (FLO) International – rubber plantations are structurally very similar to tea plantations: In India and Sri Lanka, for example, rubber and tea plantations are often run by the same operating companies – and the workforce belongs to the same unions. As far as the environment is concerned, the Fair Rubber criteria include the relevant criteria of the Forest Stewardship Council (FSC) – the majority of the supplier partners are also FSC certified (and here the Fair Rubber Association also partly finances the audit costs).
Here, you can find more information about the Fair Trade projects and the criteria for Fairly traded rubber. The Fair Rubber Association also supports the Sustainable Development Goals (SDG) set by the United Nations (UN) in 2015.
