Abstract

Glove, in particular work and/or protective glove, which has at least one indicator.

Description

The invention relates to a glove, in particular a work and/or protective glove, with an indicator.

Gloves are used in various embodiments both in professional and private everyday life, especially to protect the hands of a wearer from external influences. Depending on the design, gloves can be used to protect against mechanical stress, chemicals, electrical currents, infectious diseases and more. Gloves are usually tailored to their respective area of application and functionally optimized in order to make working with gloves as easy as possible for the wearer.

For the production of medical gloves, which are intended to create infection barriers or protect against chemicals, for example, impermeable materials are usually required, which should also be as flexible and elastic as possible. For this purpose, gloves made of plastic or rubber are used in industry, whereby the rubber represents a rubber-like and impermeable protective layer after vulcanization. Depending on the use and duration, the material becomes brittle, reducing the protective function of the gloves.

In order to be able to guarantee good hygiene in medical facilities and in care, the disposable gloves may not be worn here for longer than 30 minutes and they may only be disinfected a maximum of five times. After that, the gloves have to be changed. In intensive care areas, the Robert Koch Institute even recommends changing gloves after just 15 minutes, since the perforation rate increases the longer they are worn or after strenuous activity.

For gloves made of other materials, such as synthetic or natural fibers or synthetic or natural leather, it is not the perforation rate that matters, but other parameters. These can be, for example, the warm, humid environment inside the glove, which is influenced by the wearer’s sweat and body heat. There is a risk here that the wearer's skin will be damaged and/or pathogens such as fungi will colonize the skin. Changing it regularly is also beneficial here to ensure the skin health of the wearer.

Gloves made of metal or with metal inserts are used for activities that require a great deal of physical effort with sharp and/or pointed objects, such as work in a butcher's shop or sawmill. These gloves are heavy, which over time is detrimental to the joints in the wearer's hands and arms. In order to avoid overstressing the joints, regular breaks must be taken.

It is advantageous to use gloves that show the wearer wear and tear, wear time and/or contamination so that the wearer can change gloves in good time. The wearer of the glove preferably receives a visual indication when the glove should be changed.

A method is known from the prior art that visually indicates a necessary change of gloves. However, this procedure relates exclusively to a necessary change of gloves due to mechanical defects and is particularly common in medicine. Two differently colored gloves with the greatest possible color contrast are put on one on top of the other, so that the occurrence of holes in the outer glove is clearly visible through the contrasting inner glove, and the defective glove can be changed.

However, this method does not offer the possibility of securing a time limit on use with just one glove and thereby preventing possible material failure or the like. This is particularly important when working with infectious, toxic or otherwise harmful material, since increasing stress on the gloves over the period of use can result in damage in the form of tears or holes in the gloves, which lead to the gloves becoming permeable and thus to the pose an increasing risk to the wearer over time.

The present invention is therefore based on the object of providing a glove that signals to the wearer that the prescribed wearing time has been reached or exceeded and the glove must be changed in order to maintain the protective effect of the glove.

According to the invention, the above object is achieved by the features of claim 1. Accordingly, the glove in question, which can in particular be a work and/or protective glove, has an indicator.

In a manner according to the invention, it was initially recognized that an indicator which is dependent The ability of environmental conditions to generate a signal for the wearer of a glove can be used to indicate how long the glove has been worn. Depending on the signal and/or the intensity of the signal, the wearer can be informed that a predetermined wearing time of the glove has been reached or exceeded. This reduces the risk of the glove perforating. It also ensures that the wearer of the glove regularly checks the condition of his hands, especially the condition of the skin on his hands, and can thus prevent injuries, skin infections and overstressing of the skin and joints.

In one embodiment, the glove is at least partially made of a material or is at least partially made of a material selected from polyethylene, polyisoprene, latex, nitrile, vinyl, natural rubber, synthetic rubber, synthetic fibers, natural fibers, synthetic leather, natural leather, metal or combinations thereof. An exemplary material made from synthetic rubber is acrylonitrile butadiene rubber, also known as nitrile butadiene rubber (NBR).

Synthetic rubber and natural rubber can be a suitable starting material for the glove. Natural rubber has the advantage that no petroleum is required during production, which is environmentally friendly. Rubber becomes rubber through vulcanization, which can be further processed into rubber gloves, for example.

Latex gloves are extremely stretchy, have sufficient thickness and are durable. Thus, a latex glove offers good protection and comfort. The areas of application for latex gloves are primarily in the medical sector, in care, in gastronomy, in the cosmetics industry and in the handicraft sector.

The advantage of nitrile gloves is that no latex allergy can be triggered. The good resilience of the nitrile gloves is also particularly noteworthy. Because nitrile gloves offer good protection against many oils and chemicals and are therefore also suitable for laboratory work. Furthermore, nitrile gloves have the advantage that they are very tear-resistant and allow a very good sense of touch. Nitrile gloves are used in the medical sector, in gastronomy, in the cosmetics industry and also for manual work.

Vinyl gloves are comparatively inexpensive. Vinyl gloves are mainly used in care because they have a very soft material and are well suited for brief contact with alkalis and acids and therefore for light care and washing work.

Vinyl nitrile (Vitril) gloves are an innovative blend of nitrile and vinyl, combining the advantages of both materials.

The molecular structure of polyisoprene is similar to that of latex. Consequently, the beneficial properties of polyisoprene gloves are comparable to those of latex gloves. In addition, no latex allergies are triggered.

Polyethylene as a material for gloves has the advantage that it is cheap and widely used. In addition, polyethylene is food-safe and can therefore be used in the food industry. The density, formability, etc. can be adjusted in the production of polyethylene gloves depending on the field of use. The material can therefore be used flexibly.

The glove can also be made of synthetic or natural fibers. Synthetic fibers are fibers or threads that are made of plastics such as polyamides, polyesters, polyurethane, polyacrylic or the like. Natural fibers are fibers or threads as they occur in nature or are made from natural raw materials. Examples include fibers of plant or animal origin, such as cotton, wool from sheep or other animals, hair from animals, wood fibers, silk, linen, flax, hemp, sisal, etc.

Synthetic fibers are advantageous because they are relatively easy and inexpensive to manufacture. In addition, the thermal insulation is correspondingly good and they can be processed in many ways. Natural fibers offer good moisture wicking and thus ensure a pleasant and healthy skin climate.

The fibers can be woven, sewn, knitted or crocheted for the glove to form a glove shape or parts thereof which are subsequently assembled.

Artificial leather or leather of natural origin is also suitable for the manufacture of the glove. Leather gloves are sturdy. Leather offers good protection against cuts and punctures. In particular, robustness is an important parameter for work and/or protective gloves.

Furthermore, the glove can also contain metal or at least partially consist of metal. The metal can be in the form of chains or links for a glove or part of it result. The metal can also be incorporated into the glove as a thread or be twisted into other fibers and/or threads. The metal leads to a reinforcement of the mechanical protection of the glove and/or can also have antibiotic effects.

The glove can be roughened on the inside of the hand on individual or all fingers, for example in the front finger area of the glove, in particular the fingertips. This is particularly advantageous with typically smooth gloves, such as polyethylene, polyisoprene, latex, nitrile, vinyl, or vinyl-nitrile gloves to ensure touch screen operation and/or improve the grip of the glove wearer.

Various indicators or indicator systems can be considered for visualization. In one embodiment, the indicator is a redox indicator, pH indicator, complex indicator, light indicator, thermal indicator and/or thermochromatic liquid crystal.

In a preferred embodiment, at least one of the indicators is a redox indicator that reacts with oxygen, which preferably comes from the work environment in which the gloves are used.

A redox indicator is a reversible redox system whose reduced and oxidized forms are different colors.

It is therefore conceivable that the glove can be provided with both a reduced and an oxidized form of the indicator in the initial state, depending on the area of application.

It is conceivable that the environment in which the glove is used has a reducing effect on the redox indicator if the glove is in the initial state with an indicator in its oxidized form.

It is also possible that the gloves, which initially contain a reduced form of a redox indicator, oxidize over the period of use with the oxygen from the work environment.

Particularly suitable redox indicators can have standard potentials (E ⁰ in V) in the range from 0.1 to 1.5, preferably in the range from 0.2 to 1.3.

In a further embodiment, the use of the indicator can be matched to the amount of oxygen in the intended application environment. The quantity and/or the attachment of the indicator to the glove are preferably varied. However, it is also conceivable that an indicator mixture used is adjusted accordingly.

• • Phenosafranin
• • Indigo-tetrasulfonat
• • Methylenblau
• • Diphenylamin
• • 4'-Ethoxy-2,4-diaminoazobenzen
• • Diphenylamin-sulfonsäure
• • Diphenylbenzidin-sulfonsäure
• • Tris(2,2'-bipyridin)eisen
• • Tris(1,10-phenanthrolin)eisen (Ferroin)
• • Tris(5-nitro-1,10-phenanthrolin)eisen
• • Tris(2,2`-bipyridin)ruthenium

In a further embodiment, the redox indicator is selected from at least one of the following indicators:

• • phenosafranine
• • Indigo tetrasulfonate
• • Methylene Blue
• • Diphenylamine
• • 4'-Ethoxy-2,4-diaminoazobenzene
• • Diphenylamine sulfonic acid
• • Diphenylbenzidine sulfonic acid
• • Tris(2,2'-bipyridine)iron
• • Tris(1,10-phenanthroline)iron (ferroin)
• • Tris(5-nitro-1,10-phenanthroline)iron
• • Tris(2,2`-bipyridine)ruthenium

In another embodiment, the indicator is a pH indicator. A pH indicator can preferably indicate contact of the gloves with alkaline or acidic substances. Contact with alkaline or acidic substances could put a lot of strain on the gloves compared to contact with neutral substances, which would limit the protective effect of the gloves. The use of a pH indicator could provide a breakdown of the pH of a work environment in which the gloves are used or the pH within the glove. Inside the glove, the environment there is primarily determined by the sweat and heat of the wearer. The pH value changes depending on the sweat released.

• • Lackmus,
• • Thymolblau,
• • Bromthymolblau,
• • Bromkresolgrün
• • Methylrot
• • Alizaringelb
• • Phenolphthalein,
• • Methylorange, und
• • Universalindikatoren.

The following substances can be used as pH indicators:

• • litmus,
• • thymol blue,
• • bromothymol blue,
• • Bromocresol Green
• • Methyl Red
• • Alizarin Yellow
• • phenolphthalein,
• • methyl orange, and
• • Universal indicators.

The pH change range for the pH indicators can be between pH 1 and 12. There can be multiple transition areas for a pH indicator. For example, thymol blue has a red to yellow color change in the pH 1.2 to 2.8 range and a yellow to blue color change in the pH 8.0 to 9.6 range.

In another embodiment, the indicator is a complex indicator. The concentration of metal ions can be determined with a complex indicator. Water hardness can preferably also be determined with complex indicators, which in turn can influence the protective effect of the gloves. For example, murexide, xylenol orange, tiron or similar substances can be used as complex indicators.

In another embodiment, the indicator is a light indicator that signals exposure of the gloves to light. Preferably, such indicators primarily signal the presence of UV light, through which the material of the gloves could be additionally influenced. Since light corresponds to an electromagnetic spectrum, a corresponding indicator is generally indicative of the presence of electromagnetic radiation. The areas of the electromagnetic spectrum that can have an impact on the protective effect of the gloves are preferably indicated.

In another embodiment, the indicator is a thermal indicator that indicates the temperature of the gloves at least in the area with the indicator. Thermal indicators can preferably indicate the surface temperature and thus provide information as to whether a working environment is too hot or too cold for the gloves. Thermal indicators are preferably used above all with thermally insulating gloves, since a wearer of the gloves cannot directly feel how warm an outer surface of the gloves is and therefore cannot decide whether the gloves are being used in an environment that is too hot or too cold.

Furthermore, the gloves can react to the body heat of a wearer by means of appropriate thermal indicators and thus preferably indicate a reduction in the protective effect over the period of use. In addition, a preset course can be displayed by a thermal indicator, which ends at a certain point in time, which correlates with the maximum wearing time, which is measured via the contact, in particular the transfer of body heat.

The thermal indicator can be reversible or irreversible. Reversible thermal indicators can, for example, be reused, with irreversible thermal indicators no longer being able to be converted to their initial state after a predetermined transition point has been reached and having to be disposed of.

In another embodiment, the indicator is a thermochromatic liquid crystal that can have a different visual appearance along a temperature gradient. Liquid crystals are particularly suitable for determining surface temperatures, with the crystals having a different coloring depending on the temperature.

In a further embodiment, several of the indicator types mentioned can be attached to the glove next to one another or in combination with one another. This makes it possible to monitor various parameters that indicate the wear and tear and thus the need to change the glove.

In another embodiment, the indicator is fully or at least partially mixed into the material of the glove. In particular in the case of gloves made of plastics or rubber, the interference can already take place during the production of the materials or the production of the gloves themselves. By mixing the indicator into the starting material, it can be achieved that the indicator is uniformly distributed in the subsequent glove and can signal the necessary change to the wearer in any position of the hand.

In one embodiment, the indicator is applied directly to the glove, for example sprayed, brushed, or by at least partially immersing the gloves in a fluid containing the indicator.

In a further embodiment, the indicator is present on and/or in a carrier device which is arranged on the glove. The indicator can be variably and/or selectively located in specific areas or on specific surfaces of the glove. In particular, the surface of the glove comes into consideration here. The indicator is preferably attached at least to the points on the glove that preferably come into contact with substances to be indicated and/or the points that can be easily perceived by the wearer of the glove.

The carrier device can be detachably or non-detachably connected to the glove. A detachable connection makes it possible for the glove to be reused and only the carrier device together with the indicator to be disposed of. A non-detachable connection between the carrier device and the glove comes into consideration, in particular, in the case of disposable gloves, which are thrown away anyway after being worn once.

In a further embodiment, the carrier device is made of an absorbent material. In a further embodiment, the carrier device is a fillable container.

The carrier device can be designed in such a way that it can accommodate the indicator on and/or in itself. This can be realized, for example, by preferably using an absorbent material that can absorb the indicator. In particular, the indicator can be absorbed into the material in liquid form and can be present in and/or on this material.

The indicator can be applied to the carrier device, for example as a film. This film can be curable with suitable polymer binders. This avoids the indicator not having direct contact with the glove. This is particularly advantageous since indicators are often in the form of acids or bases and can corrode the glove material accordingly.

The material of the carrier device can be selected from plastics, plastic fibers, natural fibers, cotton wool, paper, foils, adhesives or other receptive or absorbent materials. These can be attached to the glove as strips, in particular adhesive strips, stickers, strips of fabric, pads, single or multiple applications, etc.

The carrier device can also be a fillable container. The container, such as an appropriately sized tube, bag, pouch, etc. The container must be sealed so that the indicator cannot leak. Furthermore, the container must allow the indicator to interact with the environment. This can be implemented, for example, by membranes, such as semipermeable membranes, gas-permeable membranes, size exclusion membranes, etc., which only selectively allow substances to pass through. Furthermore, it would be possible for the container to be permeable to UV radiation. In any case, it must be ensured that the glove wearer can perceive the indicator signal.

In a further embodiment, the carrier device is glued, crocheted, woven, printed, sewn, knitted, ironed, riveted and/or vulcanized to the glove. The type of fastening can be selected depending on the material and/or area of work of the glove. For example, gloves that protect the wearer from infection, chemicals, etc. should not have an attachment that penetrates the surface of the glove.

Redox indicators can be attached to strips of absorbent material or a container on the glove. In addition, the redox indicator can also be mixed into or applied to the starting material of the glove.

Thermal indicators can be applied to the glove in the form of a sticker or chalk.

Thermochromic liquid crystals are preferably applied to the glove in the form of an adhesive film.

In one embodiment, the indicator is a color indicator that shows a color change that correlates to glove usage.

A color indicator is a substance that can be used to follow the course of a chemical reaction or to characterize the state of a chemical system, with a change in state being signaled by a one- or two-color change in color.

The indicator changes color according to the environmental condition. This is called a color change. The state of the chemical system at which the change in color of the indicator occurs is referred to as the color change.

The reaction time of the indicator can be designed as desired, with reaction times of a few minutes up to several hours being possible. The reaction times can be adjusted by the concentration of the indicator and/or the environmental influences to be expected when using the indicator.

It is also conceivable that the gloves do not have a temporal reaction, but that the indicator indicates that a specific threshold value has been exceeded. A color change would thus be visible within a second. An application example would be gloves, which a maximum temperature must not be exceeded and in which a corresponding indicator signals that a maximum temperature has been exceeded.

The indicator's response can be continuous over a period of time, or it can be sudden, such as Landolt's time response. A reaction could also run exponentially, with the indicator preferably changing its indexing fastest at the end of its useful life.

In one embodiment, the indicator initially shows no reaction when the gloves are used. A change in color or a change in color can only be seen if the gloves are defective. For this purpose, the indicator is preferably arranged in the material of the gloves, whereby a defect in the glove would bring the indicator into contact with oxygen from the environment and the indicator would start to react. With this embodiment, a defective glove could preferably be indicated, which has defects, for example due to mechanical or chemical effects.

In a preferred embodiment, the indicator is a redox indicator that reacts with the oxygen in the work environment and changes color over time. Correspondingly, the effect of the indicator can be defined as a chemical or non-electrical timer.

In a further embodiment, all colors and color gradients are possible, depending on the indicators used, and preferably also a transparent representation of the indicator. The transparent form of the indicator is preferably the initial form, and this preferably changes color as the glove is used over time.

The discoloration with the period of use correlates with the reaction of the indicator with the environment, preferably with the oxygen in the air. The longer the glove is worn, the more the indicator reacts with the environment and the more clearly the color changes.

A visual change can also occur due to light and different lighting conditions and/or differences in brightness. This can happen, for example, through hypsochromic or bathochromic effects.

Other color reactions can also be induced by the following methods or modifications thereof: sunset reaction, Landolt time reaction, starch solution, Lugol's solution and amylase detection of starch, indigo staining, biochemical variants (e.g. yeast and fermentation - CO2 production).

Depending on the indicator or indicator mixture, it is conceivable that several levels are also indicated, with each level indicating proof of a service life that has been reached and/or contact with a specific substance. Preferably, corresponding gloves can be used in a variety of ways, so that depending on the application environment, a different indicator must be observed.

In a further embodiment, a color scale is arranged or depicted on the glove itself, on an outer packaging and/or an instruction leaflet, from which the wearer of the glove can recognize when a critical wearing time of the gloves has been reached. To do this, the wearer compares the color of the gloves with the color scale, the color scale having a color value that is also reached by the glove after a certain wearing time.

It is conceivable that with several indicators that are active in parallel, several color scales are available in order to be able to cover the color gradient of each indicator. The color gradients can preferably also be used to classify the remaining protective effect of the gloves, since this preferably decreases with use of the gloves.

In another embodiment, the glove further includes at least one protective device that maintains the indicator in an inactive state.

The basic function of the protective device is to protect or shield the indicator on the gloves from its underlying reaction until it is about to start.

The protective device may be a simple strip of material such as plastic, in particular a plastic strip, applied to the indicator or applied to the support device such that the indicator is isolated from the environment. The shape of the protective device is variable and adapted to the corresponding carrier device.

In one embodiment, a corresponding protective device is a package in which the glove is packaged, preferably in an airtight manner, so that it is protected from oxidation with oxygen from the ambient air.

It is conceivable that the corresponding protective device consists of plastic, biodegradable plastic or similar material that is customary in the prior art. In particular, it is possible to use all materials that ensure the gloves are airtight.

It is conceivable that the protective device can be a kind of wax layer, for example through the body when the gloves are used for the first time perwärme is removable and therefore does not have to be removed separately. A corresponding protective device can also be a substance that can be removed through the work environment in which the gloves are used and thus starts a reaction of the indicator in the gloves.

In another embodiment, the glove is placed in an overpack with the indicator in an inactive state.

The glove can be present alone or with several other gloves according to the invention in an overpack. The gloves can be stacked in this outer packaging. In an advantageous embodiment, the gloves are stacked such that the indicators are isolated from the environment. Thus, no further protective device is necessary. Additionally or alternatively, the gloves in the overpack may have a protective device on the indicator.

An outer packaging can, for example, be a container, preferably a carton, from which the gloves can be removed.

In a further embodiment, the indicator can be activated by removing the protective device and/or removing the glove from the outer packaging.

In a preferred embodiment, removing the safety device initiates the indicator's underlying response. The indicator is thus activated by the removal of the safety device. Additionally or alternatively, the mere removal of a glove from the outer packaging can also activate the indicator. This can be done by presenting the indicator, isolated from environmental influences in the stack, when the environment is removed.

In a further embodiment, the glove has a protective device which is removed from the indicator when it is removed from an outer packaging and which activates the indicator.

In a preferred embodiment, the gloves are food safe. Preferably, the gloves can also be used in food processing. It is also conceivable that the gloves correspond to medical standards and can therefore also be used for medical purposes.
