Description

GLOW-IN- THE-D ARK GLASS CONTAINER AND METHOD FOR PRODUCTION OF THE SAME

Technical Field

This invention relates to a glass container that glows when placed in a dark environment or under black light after being exposed to a source of visible light for a certain duration and a method of production of the same.

Prior art

The ground energy level or the ground state of an atom or a molecule is attained when the electrons of an atom or a molecule occupy orbitals with the lowest energy. An electron configuration wherein electrons occupy higher energy levels is defined as an excited state of an atom or a molecule. Upon exposure to a light source, some materials transition into an excited state by absorbing the radiation impinging on them. When radiation ceases, they emit photons having an energy equal to the energy gap while relaxing to the ground state from an excited state.

Visible photoluminescence falls under two categories as fluorescence and phosphorescence according to the duration of the event. (Time required for the electron to return to the ground state energy level).

If one of the two electrons of an atom or a molecule is excited to a higher energy level, a singlet or a triplet state is formed. In an excited singlet state, the spin of the excited electron is still paired with the electron in the ground state. However, in the triplet state, spins of the two electrons are in an unpaired configuration and the features of a molecule in an excited triplet state significantly differ from one in an excited singlet state. Light emitted by the transition from an excited triplet state to the ground singlet state is called phosphorescence. A triplet— » singlet transition is more likely than a singlet— » singlet transition; therefore, the average life span of an excited triplet state is longer than the life span of a singlet state and therefore an emission resulting from this transition may last a little longer after radiation ceases. Fluorescent radiation always occurs at a longer wavelength than the absorbed radiation, that is, it has a lower energy. Phosphorescence can be defined as a type of glow related to fluorescence. Unlike fluorescence, phosphorescent materials do not reemit the absorbed energy quickly. Moreover, it is unlikely that a molecule in the ground state is excited to a triplet state and the intensity of the absorption peaks resulting from this process is a few orders of magnitude lower than the similar counterparts of a singlet-singlet transition.

Phosphorescent materials find use in many fields, primarily in plastics and paints. Chemical materials with phosphorescence are supplied as pigments and they endow the surface on which they are applied with a glow in the dark property. Glass is more challenging with regards to the applicability of paints compared to many other surfaces like metal, wood, paper, composite, plastic and concrete. When existing phosphorescent paint systems are applied to a glass surface, mechanical strength and glow efficiency are found to be poor. It is possible to give glowing property to a glass by adding pigments with phosphorescent effect to the glass composition. However, in this method, phosphorescent pigments cannot be distributed homogeneously in the glass composition. In addition, this method is rather costly. Phosphorescent paints that are available in the market may be applied on different surfaces, whereas, sufficient and efficient adhesion cannot be attained on glass surfaces. When phosphorescent pigments are incorporated in non-pigmented (colorless) paint systems compatible with glass surfaces, decadence (phase separation) problems are experienced. Phosphors of type ZnS:Cu are preferred as they are cheap, but these do not provide high enough luminosity and have short phosphorescence time for many applications. U.S. document no Dl : US2004064989 (Al) discloses a container emitting phosphorescent light. This container may be glass or plastic jars or bottles or cardboard containers. There is a coating on the external surface of the container which radiates phosphorescence in the absence of a light source. In the said document, photoluminescence is provided by phosphorescent pigments. However, in the invention of this application, phosphorescent pigments are blended into a paint of choice and a coating mixture is obtained and the mixture obtained thereby is applied on a glass surface by different methods. There is no information about the pigment, the type of paint and the performance of the paint in the said Dl document.

U.S. document no US6123872 discloses a fluorescent or phosphorescent oxide glass featuring a long-lasting afterglow and light excited luminescence. In the said document, energy is stored by excitation with irradiance. Gama-ray, X-ray and UV- rays, etc. may be given as examples to these radiations. The glass mentioned in the said documents is a phosphorescent glass exhibiting long-lasting afterglow and light excited luminescence, and the chemical composition of the glass is described. However, in the invention of this application, a phosphorescent layer is applied only to the glass surface. The document cited above describes a coating made on a glass surface as an alternative, however, this coating has a problem of peeling off. In the invention of this application, the coating made on glass surface has high resilience and peeling off problem is not experienced.

U.S. document no US2003194519 (Al) discloses storage boxes for food and drink with the glow-in-the-dark feature. The box mentioned in the said document, is a blow-molded, luminescent, polyethylene storage box or bottle. Luminescence in the said boxes is obtained by blending zinc sulphide luminescent pigments from 0.075-1.2% in volume in the polyethylene resin. Boxes described in the document are plastic boxes, wherein the pigment providing phosphorescent luminescence to the boxes is based on zinc sulphide. However, in the invention of this application, strontium aluminate with a longer duration of luminescence is used as a phosphorescent pigment and phosphorescence is provided by a coating applied on glass surfaces.

Dutch document no L1029317 (C2) discloses an application of a phosphorescent pigment on a glass surface with screen printing or spray coating. One of the chemical formulas of the phosphorescent pigments applied on a photoluminescent glass is given as SrA1204:Eu,Dy. However, strontium aluminate pigment is blended into a ceramic of another type of ink system. In the invention of this application, a phosphorescent pigment is blended into a paint system and the glass surface is coated with the obtained mixture. In addition, in the document cited above, the glass used is a flat glass. However, in the invention of this application, implementation is made on cylindrical surfaces.

Japanese document no JP2002105448 (A) discloses a phosphorescent composition. The composition comprises an inorganic pigment, a fluorescent paint and a binder. The chemical formula of the pigment present in the composition described in the said document is given as SrA1204:Eu,Dy and blue-green luminescence is obtained in a dark environment. However, there is no mention of the type of surfaces used and the application method. The invention of this application features permanent glow under black light. However, in the document cited above there is no information regarding the performance of the invention under black light or the resilience and surface characteristics of the coating.

Taiwanese document no TW201534688 (A) discloses a phosphorescent paint. In the said document, the paint comprises phosphorescent powder smaller than 15 microns in size and a transparent varnish. The ratio of the pigments to the varnish in the paint disclosed in document D6 is as 0.9-1.1 : 1. The mixture obtained can be applied on many surfaces including glass but there is no information regarding the application of the mixture to a glass surface with UV curable screen printing. In the existing technique, there is not an implementation wherein a mixture which is obtained by combining phosphorescent pigments based on strontium aluminate with a paint binder system which causes minimal reduction in their effect is coated by spray, screen and buffer printing methods on glass surfaces. A mixture, which is obtained by adding phosphorescent pigments into a preferred paint system depending on the coating method, adheres strongly to a glass surface, and it enables the surface on which it is applied to glow in a dark environment and under black light in accordance with the adopted pigment's colour.

Yet another object of this invention is to provide a glass container with a coating which emits a high intensity, long-lasting visible radiation in a dark environment after being exposed to a light source and a production method of this container. Still another obj ect of this invention is to endow a glass container with a continuous glow under black light feature and a production method of this container.

Yet another object of this invention is to provide a glass container with a homogeneous coating independent of the surface geometry and a production method of this container.

Yet another object of this invention is to provide a glass container with a coating which can be applied with UV and/or heat curable paint binder by different coating methods such as spray painting, screen and buffer printing and a production method of this container. Brief Description of the Invention

A glass container glowing in the dark, which is defined in the independent claim and other claims depending on this claim made to achieve the objects of this invention comprise a chamber. The chamber is a volume in which the material at a preferred temperature is filled in and encloses the material it is filled with. It is the external surface of the chamber which faces the user and on which the coating that glows in a dark environment and with a continuous glow under black light after being exposed to a light source for a certain duration is applied. The external surface may be a layer consisting of one or more coatings on the glass portion of the chamber facing the user. On the external surface is a phosphorescent coating which glows in the dark after being exposed to a light source for a certain period time or which emits a continuous visible radiation under a source of black light. A phosphorescent coating covers all the external surface or a portion of it. The phosphorescence coating is obtained by blending a preferred paint binder and a strontium aluminate based phosphorescent pigment and by applying the said coating on the external surface. The paint transfers the incorporated phosphorescent pigment to the external surface and protects the pigment from external impact or abrasion. The pigment is the ingredient which makes the phosphorescent coating glow in a dark environment.

In the production method of a glass container which glows in the dark after being exposed to a light source for a certain duration, defined in the second independent claim and other claims dependent on this claim and realized to achieve the objects of this invention, a pre-treatment is applied in order to clean and activate the external surface in the first place. The pre-treatment on the external surface can be physical or chemical. After the pre-treatment, paint/pigment mixture ratios are determined according to the characteristics of the preferred printing. After determining the ratios, the paint system into which the phosphorescent pigments are to be blended is prepared. With the preparation of the paint system, pigments are blended into the paint and the coating process is performed. In order to prevent the separation of pigments before the coating mixture is transferred on the external surface, the mixture is stirred consistently, in a way that creates a recirculation from the bottom to the top of the stirring container which contains the paint. After mixing, paint/pigment is transferred on the external surface of the container, and the coating is cured. Finally, in order to determine whether the desired phosphorescent coating is obtained, a quality inspection is carried out by using a black light source.

100. Production method of a glass container glowing in the dark A glass container (1) glowing in a dark environment after being exposed to a light source for a certain duration or directly under black light, in its basic form, comprises:

at least one chamber (2) in which a liquid or solid material is filled, - at least one external surface (3) which is a facade of the glass container (1) facing a user,

at least one phosphorescent coating (4) which is applied on all or a portion of the external surface (3), comprising a paint binder (5) and a pigment (6), providing glow in a dark environment after being exposed to a light source for a certain duration

at least one paint binder (5) providing the transfer of the pigment (6) on the surface on which the coating is to be implemented by blending with the pigment (6), and

at least one pigment (6) emitting luminescence by emitting the excess energy as photons while the electrons of atoms or molecules are being excited to higher energy levels by excitation when they are exposed to a light source, or while the electrons are relaxing to their ground state with lower energy levels from a higher energy level in an environment without a source of energy when being exposed to a light source.

In an embodiment of the invention, there is a chamber (2). The chamber (2) is the volume in which a liquid or solid material is filled. The geometry of the chamber

(2) varies depending on the geometry of the class container (1). In an embodiment of the invention, there is an external surface (3). The external surface (3) is located on the portion of the chamber (2) facing the user and it forms the external part of the chamber (2) of the glass container (1). The external surface

(3) is a coated surface of the glass container (1). Physically and/or chemically treated external surfaces or surfaces without any treatment may be used as an external surface (3). The external surface (3) may have a smooth or non-smooth texture. The external surface (3) may be colored transparent, translucent, colorless transparent or opaque. In an alternative embodiment of the invention, the external surface (3) is an opaque white or white coated surface. The external surface's (3) being opaque white or white coated increases the duration and the intensity of the radiation of the phosphorescent coating (4) applied.

In an embodiment of the invention, there is a phosphorescent coating (4) on the external surface (3). The phosphorescent coating (4) is the form which provides the emission of luminescence in a dark environment by the object on whose surface it is coated after being exposed to a light source for a certain duration. The intensity of the effect of the phosphorescent coating (4) is proportional to the size of the pigment (6) particles blended into the paint binder (5). The phosphorescent coating (4) may glow in the dark for 0-2 hours after being exposed to a light source for a certain duration. The phosphorescent coating (4) has a characteristic of a continuous glow under a source of black light. The phosphorescent coating (4) located on the external surface (3) has a translucent or semitransparent appearance under normal light. Colorless translucent, semitransparent appearance becomes colored in a dark environment. In an alternative embodiment of the invention, another colorless, transparent coating is implemented on the phosphorescent coating (4). The transparent coating which is applied increases the endurance of the phosphorescent coating (4) against external impact and abrasion. (For example, dish washer environment, chemicals, etc.).

In an embodiment of the invention, there is a paint binder (5). The paint binder (5) is a system in which pigments (6) providing glow in the dark property after being exposed to a light source for a certain duration, are dispersed. The paint binder (5) is, at the same, the carrier which transfers the pigments (6) on a preferred surface. In this embodiment of the invention, the paint binder (5) is compatible with a glass surface. Water- or solvent-based spray, UV and/or heat curable screen printing or buffer printing paints can be used as a paint binder (5). In an embodiment of the invention, the paint binder (5) comprises; a resin, a hardener and a solvent. In another embodiment of the invention, the paint binder

(5) comprises; a resin, an activator and a solvent. In such cases, the coating mixture which is obtained by blending a paint binder (5) and phosphorescent pigments (6) is applied on the external surface (3) of the glass facing the user by methods of painting with a paint gun robot or an electrostatic disk or an electrostatic bell.

In an alternative embodiment of the invention, the paint binder (5) comprises; an UV curable resin, and an activator. In such a case, the coating mixture which is obtained by blending a paint binder (5) and pigments (6) is applied on the external surface (3) of the glass facing the user by a screen printing method.

In an alternative embodiment of the invention, the paint binder (5) comprises; a heat curable resin, and an activator. In such a case, the coating mixture which is obtained by blending a paint binder (5) and pigments (6) is applied on the external surface (3) of the glass facing the user by a buffer printing method.

In this embodiment of the invention, pigments (6) are blended into the preferred paint binder (5) system. The pigment (6) blended into the paint binder (5) is a type of pigment (6) glowing in the dark after being exposed to a light source for a certain duration. The pigment (6) can be a fluorescent and/or phosphorescent pigment (6). In a preferred embodiment of the invention, a phosphorescent pigment (6) is used because the duration of glow in the dark is longer. The ground energy level or the ground state of an atom or a molecule is formed by the settlement of electrons of an atom or a molecule in orbits with the least energy. The excited state of an atom or a molecule is formed by the settlement of electrons in higher energy levels. An excited atom or a molecule is in an unstable form and seeks to relax to the ground state by releasing the excess of energy. An atom or a molecule can release part or all of the excess energy in the form of emission while relaxing to ground state and thus an emission of light from the system is observed. In phosphorescent pigments

(6) , relaxation from an excited triplet system to a ground state singlet system takes place. The pigment (6) is blended into the paint binder (5) preferably in the form of a powder. The particle size of the pigment (6) blended into the paint binder (5) is between 0-100 microns. In a preferred embodiment of the invention, the average particle size of the pigment (6) is optimized so that it is in the range of 2-40 microns. Phosphorescence may be provided to the phosphorescent coating (4) comprising a paint binder (5) and a pigment (6) by many phosphorescent pigments (6). The pigment (6) used in the preferred embodiment of the invention is based on strontium aluminate, wherein the chemical formula is as SrAl₂0₄: Eu, Dy. The wavelength of the light emitted to the environment as a result of excitations is between 450-550 nm.

The glass container (1) of the invention may be a glass household accessory.

In an embodiment of the invention, the glass container (1) is a wine glass. There is a chamber (2) in the glass. A phosphorescent coating (4) can be performed on a portion or all of the external surface (3) of the chamber (2) of the wine glass. The wine glass with a phosphorescent coating (4) stores the energy of the light falling on it under a light source and when the light source disappears, it releases the stored energy as radiation with electron transitions occurring between energy levels present in the form of the pigment (6); thus, a product glowing in the dark is obtained.

In an embodiment of the invention, the glass container (1) is a bowl. There is a chamber (2) in the bowl. A phosphorescent coating (4) can be performed on a portion or all of the external surface (3) of the chamber (2) of the bowl. The bowl with a phosphorescent coating (4) which stores the energy of the impinging light when placed under a light source and when the source is removed, it releases the stored energy as radiation through electron transitions occurring between the energy levels of the pigment (6); thus, a product glowing in the dark is obtained.

The glass container (1) of the invention may be a glass package product. In an embodiment of the invention, the glass container (1) is a bottle. The glass package product which is a bottle can be used as a package for liquids such as olive oil, water, high alcohol, fizzy drinks, still drinks, energy drink, wine, etc. With the glass container (1) of the invention, a product which emits luminescence in an environment without a light source by releasing the stored energy after being exposed to a light source for a certain duration and which thus becomes visible.

A method for the production (100) of a glass container (1) glowing in the dark, by implementing a colored and shiny product in the dark on the external surface (3) of a glass container comprises the steps of:

a pre-treatment (101) of the external surface (3),

determining (102) the weight percentages of the paint binder (5) and the phosphorescent pigment (6) forming the phosphorescent coating (4) of the paint binder (5)/ pigment (6) ratio, preferably with a pigment (6) ratio within the range of 0-50% of the paint binder (5) in weight (w/w),

preparation (103) of the paint binder (5),

in a paint stirring container, scraping the paint binder (5) blended with a phosphorescent pigment (6) with a mixer from the bottom and stirring with a recirculation from the bottom to the top of the stirring container and obtaining the coating mixture (104),

implementing (105) the coating mixture on the external surface (3), curing (106) the phosphorescent coating (4), and

performing the quality control tests (107).

Cleanliness of the surface is important for increasing the adhesion and strengthening of the coating performed on the external surface. Thus, the external surface (3) on which the phosphorescent coating (4) is to be formed is pre-treated (101). The external surface (3) can be subjected to a physical or chemical pre- treatment. In order for the phosphorescent coating (4) which is desired to be obtained on the external surface (3) to be in a preferred form, the ratio of the paint binder (5) / phosphorescent pigment (6) forming the phosphorescent coating (4) is determined (102) according to the overall weight of the mixture. In this step of the process, the weights of the paint binder (5) and the phosphorescent pigment (6) forming the phosphorescent coating (4) are determined as weight percentages. In an embodiment of the invention, the proportion of the pigment (6) is in the range of 0- 50% (w/w) of the weight of the paint binder (5). For example, 30% pigment (6), that is 30 grams of pigment (6) is used for 100 grams of paint binder (5). The weight of the coating mixture obtained within the frame of these percentages is 130 grams.

After the paint binder (5) / pigment (6) ratio is determined, the paint system in which the pigment (6) is to be added and mixed is prepared (103). The paint to be used can comprise various components according to the type of the preferred application. The paint binder (5) can comprise components such as a resin, an activator and a hardener and additives. In the preparation (103) of the paint binder (5) for use, components such as the resin and the activator to be added to the resin or the hardener, etc. and the additives are mixed proportionally. The paint binder (5) which is one of the components forming the phosphorescent coating (4) both provides adhesion onto the external surface (3) and increases the resilience of the pigment (6) blended therein.

After the paint binder (5) / phosphorescent pigment (6) ratio is determined (102) and the paint binder (5) is prepared (103), a coating mixture is obtained (104) by blending phosphorescent pigments (6) into the paint binder (5). The intensity of the phosphorescent pigments (6) is rather high compared to the previous examples referred to in the introduction. Especially in spray paint systems having low density, the phosphorescent pigment (6) tends to precipitate. In order to prevent the pigments (6) from phase separation within the paint binder (5) and to maintain the homogenous form of the mixture, stirring is performed during the application. The process of stirring after addition of the pigment (6) into the paint binder (5) is continuous and it is performed by two different simultaneous methods. The paint binder (5) with added phosphorescent pigment (6) is transferred into a paint stirring container. While the paint binder (5) with phosphorescent pigment (6) in the paint stirring container is stirred by scraping with a mixer from the bottom; the stirred paint is concurrently re-circulated from the bottom to the top of the stirring container. Blending the pigments (6) into the paint binder (5) and obtaining (104) the coating mixture is preferably performed at room temperature, under atmospheric pressure. The stirring process continues until the process is completed. After the coating mixture is obtained, it is applied (105) on the external surface (3). The coating mixture can be implemented on all or a portion of the external surface (3) by various painting techniques using a paint gun robot, an electrostatic disk or an electrostatic bell; or can applied on the external surface (3) using techniques such as screen printing, and buffer printing when a patterned decoration is preferred.

After the coating mixture is applied (105) on the external surface (3), the curing (106) process of the phosphorescent coating (4) is performed for the phosphorescent coating (4) to form a permanent film layer on the external surface (3). The curing (106) process of the phosphorescent coating (4) is performed by UV or heat treatment depending on the type of the preferred paint binder (5). .In the curing

(106) step of the phosphorescent coating (4); a resin system which called a varnish hardens by chemically binding after the activation of functional end groups present in its structure by UV and/or heat treatment and forms a permanent phosphorescent coating (4) on the external surface (3).

After the curing process (106) of the paint is completed, control tests are performed

(107) for the purpose of determining whether the obtained product is phosphorescent. The glass container (1) with a phosphorescent coating (4) on the external surface (3) is first exposed to light manually. The glass container (1) exposed to a light source is transferred to a dark environment in order for phosphorescent effect to appear. Alternatively, the glass container (1) with a phosphorescent coating (4) on the external surface (3) is brought under a black light source, wherein it is checked for whether it emits radiation under black light or not. If the preferred phosphorescence effect is achieved (1), it is exposed to dish washer, scratch and pen hardness tests.
