Description

State of the art

The present invention relates to a lighting device for illuminating a container.

In particular, in environments in which a low ambient brightness is present, such. As bars or discotheques, often containers, typically bottles, or their contents are offered for sale. It proves advantageous if such a container is presented particularly attractive to the consumer. Therefore, lighting devices for illuminating containers are known from the prior art. So revealed the EP 23 23 912 B2 For example, a lighting device for attachment to a container.

Since such a lighting device should be as compatible as possible with a plurality of different containers, it is desirable to provide a lighting device which optimally adapts to and reliably adheres to different types and shapes of containers.

Disclosure of the invention

The illuminating device according to the invention for illuminating a container comprises a foil which has a first surface which is at least partially coated with an adhesive, a flexible component carrier on which at least one electrical luminous means is arranged, and a deformable connecting layer which lies between the foil and the foil flexible component carrier is arranged, wherein the flexible component carrier is arranged on the deformable connection layer on a first portion of the first surface of the film.

A film is a flat workpiece, which is typically made of a plastic. A film is characterized in particular by the fact that it is deformable, in particular foldable, without causing any structural damage to the film. A flexible component carrier is in particular a flexible circuit board. Flexible component carrier are characterized by the fact that they can be wound in, without causing damage to the component carrier. Flexible component carriers are particularly suitable for adapting to a surface on which they rest. A deformable connection layer is a flexible, in particular elastic layer. The terms flexible and deformable are to be understood in the sense of the invention such that a change in shape can take place which takes place within the framework of a proper use of the lighting device, ie without the application of unusual forces.

Such a lighting device is advantageous because it can optimally adapt to a structure of a container, for example to the shape of a bottle bottom. The lighting device is particularly suitable for being arranged in a portion of a cavity of a container, for example within a camber of a bottle bottom. In particular, the lighting device does not comprise any large-area rigid elements which require a special spatial extent of the cavity.

The flexible component carrier may, for example, buckle when it is inserted into the cavity. Since a flexible component carrier is typically deformable under a greater force than a foil, it is necessary to prevent the flexible component carrier from becoming detached from the foil. The same applies if the component carrier is deformable under a lower force than the film. This is achieved in particular by the deformable connection layer. Deformation of the deformable tie layer allows the foil to have a greater curvature than the flexible component carrier. Distance between the flexible component carrier and the foil, which is not constant over the surface of the flexible component carrier, is compensated. Thus, distance differences between the film and the flexible component carrier can be compensated by the deformable connecting layer. Thus, the entire lighting device can rest particularly close to a surface of the container. In particular, an area is maximized at which the film in an area in which it is coated with adhesive, can rest against the container. It is thus an adhesive surface increases and optimizes adhesion of the lighting device to the container.

The dependent claims show preferred developments of the invention.

Preferably, the deformable connecting layer consists of a material, for. As a flexible polymeric material, for the deformation of a lower force is required than for a deformation of the flexible component carrier. Such materials are well known and available. Examples are elastomers and foams. In other words, this means that the material of the deformable connection layer is selected with regard to a thickness of the deformable connection layer such that the deformable connection layer deforms more than the flexible one A component carrier, when a force is exerted on the flexible component carrier via the deformable connection layer. A deviating deformation of the flexible component carrier relative to the film is thus compensated by the deformable connection layer.

Furthermore, it is advantageous if the deformable connecting layer of a foamed material, in particular foam or foam rubber, for. Cell rubber, sponge rubber, sponge rubber, or a textile fiber material, e.g. B. felt or nonwoven, consists. These materials are particularly suitable for being easily secured, for example by means of an adhesive, between the film and the flexible component carrier. Furthermore, these materials are particularly advantageous in order to compensate for possible unevenness on an underside of the flexible component carrier, ie on the side of the deformable connection layer. It is thus avoided damage to the film. An advantageous textile fiber material is felt.

It is also advantageous if a battery is arranged on the component carrier, wherein the battery is contacted by means of two contact elements and is fastened to the flexible component carrier, wherein each of the contact elements is connected to exactly one contact point with the flexible component carrier.

Batteries often have in their dimension a large area compared to a surface of the flexible component carrier. Batteries are typically neither flexible nor deformable. By fixing and contacting the battery by means of two contact elements, it is possible that deforms the flexible component carrier, wherein the battery is not subject to deformation. Optionally, it only comes to a deformation of the contact elements.

Furthermore, it is advantageous if the flexible component carrier is circulated in its circumference by a sealing element, which is likewise arranged on the foil. The scope of the flexible component carrier is to be understood as meaning a surface circumference of a surface on which some of the electrical components are arranged. In this way, an additional distance between the film and a bottom of the container can be created. If a cavity in the bottom of the container is not sufficient to receive the deformable connection layer and the flexible component carrier with the electric lamp therein, additional space is created in this way.

The second portion of the film is coated at least in some areas with adhesive. In one embodiment, the entire second portion is coated with adhesive. In another embodiment, only segments of the second portion are coated with adhesive. The type and proportion of the adhesive coating can be selected according to the purpose of use. It is also advantageous if at least one protective element is arranged on the adhesive layer. In one embodiment, a plurality of peelable protective elements are arranged in a second portion of the film, which are independently removable from the film. The peelable protective elements protect the surface or adhesive on the first surface. A peelable protective element can be peeled off the film and exposes the adhesive coated surface in this area. This principle is known from so-called stickers or stickers. Because a plurality of peelable protective elements are arranged on the foil, only a partial area of the adhesive-coated first surface can be exposed. Conversely, this means that the portion in which the peelable protective elements continue to be disposed remains protected. This is advantageous since it makes it possible for individual protective elements to be removed at a later point in time, which makes it possible to use the lighting device several times on different containers.

It is also advantageous if on the flexible component carrier on the side of the film, a first switching element is arranged, which is adapted to activate the lighting means. In this way, the first switching element is also accessible when the lighting device is glued to the container.

Furthermore, it is advantageous if the deformable connection layer has a recess in which the first switching element is arranged. It is thus avoided that an increased force is necessary to operate the first switching element.

Further, it is advantageous if a second switching element is further arranged on the flexible component carrier, which is adapted to prevent activation of the luminous means by the first switching element. This ensures that a backup against accidental activation of the lighting device is possible if it is detached from the container and should be kept for later use.

It is also advantageous if the lighting means is adapted to emit different colors as a function of a temperature, wherein the lighting device preferably comprises a temperature sensor and / or a thermochromic element in order to select a color enable. By using a temperature sensor and a color change of the lamp, a particularly strong color effect can be achieved. The lighting means may be a combination of several luminous elements, which are adapted to each radiate a different color. By the thermochromatic element, a particularly reliable solution is achieved, wherein the lighting device can be easily adapted to a desired color for the color change.

Embodiments of the invention

1 shows a cross section through a lighting device 1 for lighting a container 100 according to a first embodiment of the invention.

The lighting device 1 includes a foil 2 which is a first surface 3 which is at least partially coated with an adhesive. The foil 2 is in this first embodiment, a so-called adhesive film. The foil 2 is in a production of the lighting device 1 punched out of a foil surface. Here is an outer contour of the film 2 chosen so that this a bottom impression of the container 100 corresponds to where the lighting device 1 preferably to be attached. Such is an outer circumference of the film 2 circular in this first embodiment.

The lighting device 1 also has a flexible component carrier 4 on, on which at least one electric light source 5 is arranged. The flexible component carrier 4 is formed in this first embodiment of the invention by a circular flexible board. On the flexible component carrier 4 are interconnects arranged. The light source 5 is a light emitting diode. Preferred are on the flexible component carrier 4 several bulbs 5 arranged. Furthermore, on the flexible component carrier 4 a battery 8th arranged. Furthermore, on the flexible component carrier 4 a first switching element 16 and a second switching element 17 arranged.

The light source 5 , the battery 8th and the second switching element 17 are on one of the slides 2 remote side of the flexible component carrier 4 arranged. The first switching element 16 is on the side of the slide 2 of the flexible component carrier 4 arranged. The first switching element 16 is a pressure switch. The second switching element 17 is a slide switch.

The battery 8th is by means of two contact elements 9 . 10 attached to the flexible component carrier and is contacted via this. The battery 8th provides a voltage to supply the bulb 5 ready. The battery 8th is a button cell. A first pole of the battery 8th is via a first contact element 9 the contact elements 9 . 10 at a first contact point 11 with the flexible component carrier 4 connected. A second pole of the battery 8th is via a second contact element 10 the contact elements 9 . 10 with a second contact point with the flexible component carrier 4 connected. The battery is over the contact elements 9 . 10 with the tracks of the flexible component carrier 4 connected. The battery 8th , the bulbs 5 , the first switching element 16 and the second switching element 17 are interconnected in such a way that the luminous element 5 by an actuation of the first switching element 16 can be activated when the second switching element 17 in a first switching position, and the lighting means 5 through the switching element 16 can not be activated when the second switching element 17 in a second switching position. The first switching element 16 is thus by means of the switch 17 deactivated. The light source 5 can by the second switching element against unintentional activation by the first switching element 16 be secured. The first switching element 16 is a pressure switch. The first switching element 16 is on one of the slide 2 facing side of the flexible component carrier 4 arranged.

Further, on the film 2 facing side of the flexible component carrier 4 a deformable tie layer 6 arranged. The deformable connecting layer 6 lies with a first page on the first surface 3 the foil 2 on and is glued to this. A second side of the deformable tie layer 6 which is one of the first side of the deformable tie layer 6 opposite side is on the slide 2 facing side of the flexible component carrier 4 on and is glued to this. The deformable connecting layer 6 is thus between the film 2 and the flexible component carrier 4 arranged and connects these with each other. The deformable connecting layer 6 covers the entire surface of the flexible component carrier 4 , which of the film 2 facing, except for a region in which the first switching element 16 is arranged. The deformable connecting layer 6 does not cover the entire first surface 3 the foil 2 because the film 2 has a larger dimension in its surface than the flexible component carrier 4 , The flexible component carrier 4 is thus on the deformable connection layer 6 on a first section 7 the first surface 3 the foil 2 arranged. A second subarea 14 the first surface 3 the foil 2 is the partial area on which the deformable connecting layer 6 is not arranged.

As the switching element 16 also between the film 2 and the flexible component carrier 4 is arranged, has the deformable connection layer 6 a recess in which the switching element 16 is arranged. The switching element 16 thus becomes of the deformable connection layer 6 circulate.

Will the switching element 16 pressed, and is the switch 17 in the first switching position, so the light bulb 2 activated. The switching element 16 is thus on the flexible component carrier 4 on the side of the slide 2 arranged and is adapted to the bulbs 2 to activate.

The deformable connecting layer 6 consists of a material which is chosen such that for a deformation of the deformable bonding layer 6 a lower force is required than for a deformation of the flexible component carrier 4 , This is the deformable connection layer 6 made of a foamed material, here foam. It is likewise advantageous if the deformable connecting layer 6 made of a textile material. It turns out that the lighting device 1 has a kind of sandwich structure or a layered structure. Here is a first layer of the film 2 , a second layer of the deformable tie layer 6 and a third layer of the flexible component carrier 4 educated. Here is the slide 2 very easy to deform, the deformable connecting layer 6 more difficult to deform than the foil 2 and the flexible component carrier 4 more difficult to deform than the deformable tie layer 6 , A hardness of the materials to be selected results from a thickness of the respective layers. Conversely, a thickness of the layers results from the materials from which the respective layers are formed.

2 shows the lighting device 1 according to the first embodiment of the invention in a plan view. In the center of the lighting device 1 is the battery 8th on the flexible component carrier 4 to recognize. In this case, the circular surface circumference of the flexible component carrier 4 and the circular area perimeter of the film 2 seen. To the component carrier 4 around is the second part 14 the foil 2 recognizable. This is coated with the adhesive so that there is an adhesive layer on it. In order to prevent wear of the adhesive before it comes to a use of the lighting device 1 on the container 100 comes, this one is with a peelable protective film 15 protected. This principle is known in the field of foil-type stickers. This peelable protective film 15 includes several removable protective elements 15a . 15b , The protective film 15 has the shape of a circular ring. Here is the protective film 15 divided into eight equal angle elements, which the individual peelable protective elements 15a . 15b to shape. The individual protection elements 15a . 15b are separated from each other so that they are independent of the film 2 are removable. So are the peelable protective elements 15a . 15b for example, separated by a perforation. Thus, the user is free, only some of the protective elements 15a . 15b from the slide 2 to peel off and expose the underlying adhesive layer to the lighting device 1 on a container 100 to fix. It may thus, for example, in a first application, a first peelable protective element 15 are deducted and starting from the first peelable protective element 15a every second further protective element to be detached to the lighting device 1 on the container 100 to fix. In a second application, all other protection elements, including one to the first protection element 15a adjacent second protection element 15b , be replaced.

3 shows an exemplary arrangement of the lighting device 1 on the container 100 , The container 100 is a bottle in this first embodiment 100 , A bottom of the container 100 Therefore, has a typical for a bottle bottom buckle. This curvature creates a cavity at the bottom of the container 100 educated. An outer edge 101 the bottom of the Container forms a ring on which the container comes to rest, if this is turned off. This edge 101 revolves around the cavity 102 , Will the lighting device 1 with the foil 2 on the container 100 glued, this is typically done in the area of this outer edge 101 , However, this typically has no flat surface, but is curved in itself. Therefore, it is advantageous if the film 2 flexible, so as not to stretch over the arched edge 101 to lay and thus the largest possible contact surface between the film, the adhesive applied to the film and the container 100 to accomplish.

As in 3 However, it can be seen that it comes from the fact that the film 2 is not just clamped, to a deformation of the film 2 , For example, a curvature, in the area of the first subarea 7 the first surface 3 the foil 2 , Therefore, there is also a deformation, here a curvature, the deformable compound layer 6 and the flexible component carrier 4 , Such deformation can be further enhanced by the fact that the flexible component carrier 4 and / or the electrical components mounted thereon with the cavity of the container 100 stay in contact. Also, it can lead to increased deformation when the film 2 also in an area within the border 101 with the bottom of the container 100 is glued. It can thus lead to a different degree of deformation of the flexible component carrier 4 and the foil 2 come. This is inventively by the deformable compound layer 6 damped, so that a detachment of the flexible component carrier 4 from the slide 2 is avoided.

4 shows a representation of the deformable connection layer 6 , The deformable connecting layer 6 has substantially the shape of a circular disc, which has a same radius, as well as the flexible component carrier 4 , In this case, the deformable connection layer 6 a recording 18 on, which is suitable, the first switching element 16 to be arranged in it, if the deformable connection layer 6 on the flexible component carrier 4 rests. The receptacle is a through opening in this first embodiment. Alternatively, the receptacle is an area of the deformable connecting layer 6 having a reduced thickness relative to the surrounding areas.

5 shows a cross section through a lighting device 1 for lighting a container 100 according to a second embodiment of the invention. The second embodiment of the invention substantially corresponds to the first embodiment of the invention. However, it is along an outer periphery of the film 2 on the first surface 3 a sealing element 13 arranged. The sealing element 13 is a circular ring. The sealing element 13 revolves along the first surface 3 the foil 2 the flexible component carrier 4 in its scope. An outer circumference of the sealing element 13 corresponds to an outer circumference of the film 2 , The sealing element 13 is a flexible element. The sealing element 13 is on the first surface 3 the foil 2 arranged. The sealing element 13 has a height above the slide 2 which is greater than a height of the remaining components of the lighting device 1 over the slide 2 , Thus, the flexible component carrier 4 and the electrical lamps located thereon through the sealing element 13 protected.

6 shows the lighting device 1 according to the second embodiment of the invention in a plan view. It can be seen that the sealing element 13 with the foil 2 is glued, as these in the second subarea 14 on the slide 2 rests in which the adhesive is applied. To a corresponding bonding of the lighting device 1 with the container 100 to allow is an adhesive layer on one of the film 2 opposite side of the sealing element 13 arranged. This is according to the first embodiment of the invention protected by a plurality of peelable protective elements, which of the sealing element 13 can be removed if necessary.

In addition to the disclosure above, reference is explicitly made to the disclosure of the figures.
