The invention involves a device for putting an anti-mite agent into a mattress. In order to ensure that a mattress is not just sprayed on the surface with an anti-mite agent, it is proposed to provide a corresponding device with structural components which have at least one hollow needle, with which an outer covering of a mattress is punctured so that a mattress can be vaccinated using these devices with anti-mite agent.
A pull band for an inflatable air mattress particularly of medium and large sizes to provide for the mattress excellent elongation and self-balanced mechanism is divided into an upper and a lower portions to respectively jointed to the upper and the lower perimeters of the mattress in symmetric, corresponding and inverse fashion to form an enclosure for providing pull strength to regulate the form of and to support the mattress; the band yielding support for the mattress saturated with the air to effectively cope with external pressure for maintaining in shape; and the mattress being automatically restored to its shape once the external pressure is released.
The invention here provides a support, in particular a mattress or a part of a mattress, that preferably has a number of layers (11, 12) of elastic tubes (13). The tubes (13) of each layer (11 and 12) extend parallel to one another. The tubes (13) of different layers (11, 12), however, extend in a preferably crosswise manner to one another. Due to the elastic tubes (13), the inventive support or mattress provides a high degree of sitting and lying comfort with amazingly simple means.
