Description

FIELD OF THE INVENTION

[0001] This invention relates to a novelty soap bar and to a special effect cartridge for use in a novelty item of merchandise.

BACKGROUND OF THE INVENTION

[0002] Novelty soap bars exist in various shapes, colours and fragrances for the pleasure of the owner and end user. One soap bar described in U.S. Pat. No. 6,116,573 provides a light source which is activated whenever the soap bar is wet.

[0003] An object of this invention is to provide a soap bar which provides still more entertainment than an illuminated soap bar.

SUMMARY OF THE INVENTION

[0004] In accordance with one aspect of this invention, there is provided a soap bar having a special effect cartridge for producing light effects through an image.

[0005] The special effect cartridge has a sealed chamber through which light is transmitted and which houses an electronic circuit and a power source. A light source provided in the sealed chamber is optionally mounted to a support spaced from a translucent portion of a housing where an image is mounted. In this way, the image is backlit whenever the light source is actuated.

[0006] Actuation may take place by movement or by wetting the soap bar in a conductive medium. The soap bar has at least one movement actuated switch or a wet switch in the form of a pair of electric probes.

[0007] In accordance with another aspect of the invention, the soap bar has a loudspeaker in a discrete housing which defines an open acoustic chamber through which sound is transmitted.

[0012] FIG. 4 is a partially sectioned perspective view from the top of the special effect cartridge of FIG. 3; and

[0013] FIG. 5 is a partially sectioned elevational view of the special effect cartridge of FIG. 3.

DESCRIPTION OF PREFERRED EMBODIMENT

[0014] A soap bar in accordance with the invention is generally indicated in the drawings by reference numeral 20. The soap bar 20 has a soap body 22 which is somewhat oblong with a rounded exterior surface and a central cavity 24 which extends through the soap body 22 through opposite upper and lower surfaces of the soap body. The soap body 22 effectively has the shape of a toroid or donut.

[0015] A special effect cartridge 26 is disposed in the cavity 24. In FIG. 1, it will be seen that the top surface 39 of the special effect cartridge 26 has a series of three arcuate openings 28 disposed on one side of the special effect cartridge.

[0016] In the bottom view of the soap bar 20 shown in FIG. 2, it will be seen that the special effect cartridge 26 has a single drain hole 32 formed in a bottom surface 41 thereof and an access slot 34 exposing a pair of spaced apart electric probes 36 which will be described in more detail below.

[0017] Now turning to FIG. 3, it will be seen that the special effect cartridge 26 has an upper casing 38 which is coupled to a lower casing 40 and which together encapsulate the components of the special effect cartridge. The upper casing 38 defines the top surface 39 for the special effect cartridge 26 which is translucent in order to allow light to be transmitted through the cartridge and has dependent side walls which engage corresponding side walls of the lower casing 40. The lower casing 40 defines the bottom surface 41 of the special effect cartridge 26 and is made of an opaque material.

[0018] A ridge is formed in the lower casing 40 at the junction with the upper casing 38. The ridge serves to hold the special effect cartridge inside the soap body 22 which is formed around the pre-assembled cartridge 26 during fabrication of the soap.

[0019] A first housing 42 defines a sealed chamber 44 within the special effect cartridge 26. The first housing 42 is defined by upright portions which sealingly engage the top translucent portion of the upper casing 38 at one end and a dividing wall at the other end which also forms part of a second housing 46. The first housing 42 has a substructure consisting of a light support 48 which sealingly engages a light source in the form of a miniature bulb 50 or led so that it is downwardly spaced from the translucent top surface 39 of the upper casing 38. An image slide in the form of a disc 52 is mounted beneath the top translucent surface 39 of the upper casing 38 and is spaced from the light bulb 50 so that the image of the disc 52 will be back lit. Conveniently, the light support 48 may have a metalized surface 53 opposite to the translucent portion in order to reflect light and enhance the image.

[0020] A pair of batteries 54 is supported inside the sealed chamber 44 and electrically coupled to the light bulb 50 and to a printed circuit board assembly which is generally indicated by reference numeral 56. The printed circuit board assembly 56 forms part of an electronic circuit which includes a programmable integrated circuit for performing a predetermined sequence of light and sound effects when actuated by a switch.

[0021] In the embodiment illustrated, there are two switches, namely a movement actuated electrical switch 58 mounted to the printed circuit board assembly 56 and received inside the sealed chamber 44 and also a wet switch comprising the spaced apart electric probes 36 which are external to the first housing 42 and which are electrically coupled to the both light and sound and is not limited to producing the two together. Also, the triggering of any special effects may be done by either movement or wetting of the soap bar or both movement and wetting of the soap bar. It will also be understood that the image disc 52 and the light support 48 for spacing the light bulb from the image disc are optional and that they may be substituted by other imaging modules.

[0022] As will readily be apparent, the special effect cartridge may be incorporated, and modified as necessary, for use in a body other than a soap bar. The special effect cartridge could readily be transformed for use in a novelty item of merchandise.
