Title: Suitcase

The invention relates to a suitcase.

With conventional suitcases, there is a risk of complications in darkness or poor conditions.

Under certain lighting conditions, there is a risk that these items will not be visible or will be difficult to see. This can be particularly true at airports, train stations, or in...

Public transport can be problematic if luggage is left in poorly lit areas.

It is therefore the object of the present invention to improve visibility and

to improve lighting conditions.

The suitcase according to the invention is characterized in that at least one component of the suitcase consists of a material in which a phosphorescent material, in particular homogeneously, is distributed.

This property allows the suitcase to recover from exposure to

To shine a light, which improves the visibility and findability of the suitcase in darkness or poor lighting conditions.

As mentioned earlier, conventional suitcases are difficult or impossible to see in darkness or poor lighting conditions. The suitcase according to the invention significantly improves visibility and makes it easier to locate the luggage.

Because at least one component of the suitcase is made from a

The material is manufactured in which a phosphorescent material is produced.

Visibility of the suitcase is ensured long before it is in the

Light cone of an external light source device.

The suitcase can advantageously be designed such that at least one of the following (possible) components of a suitcase according to the invention is included.

The suitcase is made of a material containing a phosphorescent element.

The material, in particular homogeneously distributed, consists of: at least one suitcase shell, two suitcase shells connected by hinges, a handle by which the suitcase can be carried, and a handle, in particular an extendable one, on which the

Suitcases that can be pulled or pushed on wheels must have at least one locking mechanism for securing them.

suitcase shells in the closed position, e rolling element, in particular suitcase roller or suitcase wheel, e holder for a rolling element, e impact protection corner.

Preferably, at least one component of the suitcase should continue to glow even after Uber has maintained a signal with the device for an extended period of time.

Ambient light is absent, for example in the event of a power outage and generally in evening and nighttime darkness.

Preferably, the suitcase according to the invention is designed such that radiation in the non-visible frequency range is also blocked.

Upconversion or downconversion in one of the case shells, especially both case shells, and/or the handle is converted into visible light, contributing to an intense afterglow and/or long afterglow.

This design is particularly advantageous because it allows for a particularly intense and at the same time a particularly long afterglow.

In particular, it was advantageously recognized according to the invention that a phosphorescent material made of SrAl2O4:Eu?*, Dy* and/or

The suitcase is made from a mixture of raw materials containing the phosphorescent material.

As already mentioned, it may be advantageous to provide for the following:

The raw material mixture is an injection molding granulate or contains an injection molding granulate.

In a particularly advantageous way, the raw material mixture can be

The mixture consists of particles, some of which are made of the phosphorescent material, while others are not. The latter may consist, for example, of thermoplastic polymer particles, thermoset particles, and/or elastomer particles.

In particular, the other part can advantageously be made from ABS particles (acrylonitrile-

This is particularly advantageous with regard to an intensive and long [activity/situation].

Afterglow is a mixture of raw materials in which the mass fraction of

Particles from the phosphorescent material attached to the mixture in the

range of 20% to 40%, in particular in the range of 25% to 35%, or is 30%.

The particles consisting of the phosphorescent material preferably have a mean diameter that is less than 30 mm, or that is in the range of 20 mm to 30 mm, or that is 25 mm.

Such a particle size is particularly advantageous in order to achieve an intense and long afterglow and at the same time sufficient stability, especially in the injection molding process, of at least one component of the suitcase.

It can be advantageous for both suitcase shells to be made of the same material. It is also possible that the

Suitcase shells and another component are made from the same material.

In a particularly advantageous way, at least one component of the
