Cap for hearing protection

Abstract

The present invention relates to a cap intended for use as hearing protection and adapted to enclosed the external ear of a user, comprising a cap shell (4) at least partly made of a substantially transparent material, characterized in that the cap (3) is arranged to support at least one object or layer (9) on the side of the cap shell (4) which, in use of the cap (3), is arranged to face the user, and that said object or layer (9) is visible through the cap shell (4). The present invention also concerns a method of producing such a cap.

Description

CROSS-REFERENCE [0001] This is a continuation-in-part of PCT application PCT / SE2005 / 000924 filed 16 Jun. 2005 which claimed priority from Swedish patent application No. 0401537-6 filed 16 Jun. 2004.FIELD OF THE INVENTION [0002] The present invention relates to a cap intended for use as hearing protection by blocking environmental noise and is adapted to press against enclose the external ear of a user. The cap comprises a cap shell which is at least partly made of a substantially transparent material. Moreover the present invention relates to a method of producing a cap intended for use as hearing protection. BACKGROUND ART [0003] A common type of hearing protection comprises two caps which are connected by a headband. The headband is adapted to be placed over the head of the user and the two caps are adapted to be arranged one on each side of the user's head so as to enclose both external ears of the user. The cap in turn comprises a cap shell, which usually is made of plastic, a s...

Benefits of technology

[0024] In another preferred embodiment, the above-mentioned method also comprises the step of supplying, after removing from the mold the cap shell produced in the mold, an object or layer on a side of the cap shell, which side is adapted to face the user, said object or layer being visible through the cap shell. In this way, information can easily be supplied, which is specific, for instance, for one customer although the customer buys only a limited number of hearing protectors. This information can be, for instance, a printed decal with the logotype of the company. It is also possible to use this method for applying a layer of colored varnish, fluorescent paint or varnish, or the like, to provide color coding of some kind. As mentioned above, this can also be used in combination with raised patterns, subsequent application of a decal or fixing an object by molding.

Problems solved by technology

This could be the case, for instance, in outdoor work at night where it may be difficult to ensure satisfactory main lighting.

With conventional caps, it would be necessary to make a compromise between providing the cap with an unwieldy encapsulation of the diode and other electronics on the outside of the cap and being forced to accept that the diode and the electronics are easily damaged in careless handling of the caps.
