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

[0021] As mentioned above in connection with the cap, a cost-effective solution is achieved by this method since it is possible to mass-produce the cap shells without a customer-specific distinction between them and a technically suitable manner of applying the customer-specific information is achieved since this information, for instance in the form of a printed logotype or decal, is protected by the cap shell and thus is not worn off in the manner as is a print or decal subsequently applied to the outside. A number of additional advantages of the inventive method of producing the cap have been discussed in detail in connection with the inventive cap and, for the sake of clarity, it should be noted that these advantages are also achieved by the above-mentioned method of producing the cap.

[0022] The step of providing a cap shell advantageously comprises at least the steps of providing an openable and closable mold which in the closed state defines a cavity, supplying at least one substantially transparent polymer material in a moldable state to the cavity defined by the mold to produce a cap shell, and removing from the mold the cap shell produced in the mold. In accordance with this method, caps can be produced in commercially effective and conventionally tested manufacturing processes at a commercially acceptable price and with satisfactory quality.

[0023] In a preferred embodiment, the method comprises the step of supplying, before the step of supplying a polymer material to the cavity, ...

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 providin...
