Razor Having A ConnectorCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application Serial Number 63 / 586,651 , filed September 29, 2023, the entirety of which is incorporated by reference herein.BACKGROUND OF THE INVENTION1. Technical Field

[0002] This disclosure relates generally to razors and implements for reducing the length of hair, and more particularly, razors that are manual or for wet shaving having connecting structures between the cartridge and handle.2. Background Information

[0003] Razors of the wet shave type or the manual type include a cartridge and a handle that are connected. Some razors are disposable systems, where the cartridge is attached to the handle and meant to be discarded after the cartridge is exhausted (e.g., the blades are dull). Some razors are system razors where the cartridge is attached to the handle and the cartridge can be replaced with a new cartridge once the cartridge is exhausted. In either case, razors include connecting structures to attach the cartridge to the handle. Some connecting structures are direct structures, where features on the handle attach to features on the cartridge. Some connecting structures require a separate component such that the separate component - a connector - matingly engages the cartridge and matingly engages the handle. Such a connector may be included with the cartridge such that the connector and cartridge are positioned to the consumer as a single item.

[0004] Due to the number of razor cartridges available, it is desirous to have the ability to connect or adapt certain cartridges to attach to certain handles, or in other words, enable a variety of cartridges to attach to a variety of handles. It is further desirable to ensure a sufficient connection between a razor cartridge and a handle is achieved such that the razor cartridge, during use, mitigates against movement (e.g., other than cartridge pivot) when connected to the handle or otherwise disconnects from the handle. Accordingly, improvements in connectors between razor handles and razor cartridges are desired, amongst other features and methods for manufacturing razors in general.SUMMARY

[0097] Referring now to exemplary FIGS. 13-23, the connection between the connector 24 and the handle 26 will be described in greater detail. One or both of the connector 24 and handle 26 are moved towards each other such that the tongue 166 is aligned with the central longitudinal axis 128 of the connector 24. The distal end 170 of the front region 172 of the tongue 166 enters the handle receiving opening 124 and thereafter into the connecting portion 130 of the cavity 122. The pair of rails 180 on the connecting region 162 engages the guide feature126 such that the channel 182 permits the tongue 166 to move and / or slide along the guide feature 126 into the connecting portion 130. As the tongue 166 moves into the connecting portion 130, one or more engagement features 132 establish a connection between the connector 24 and handle 26. Once the engagement feature 132 has established a connection, the platform 164 will be proximal to, adjacent to, and / or flush with the handle entrance surface 117. The base region 168 of the tongue 166 will be proximal to, adjacent to, and / or flush with the handle receiving opening 124.

[0098] The engagement features 132 establish a connection by one or more of the following: a friction fit, a press-fit, an interference fit, at least one latch 137 connection, at least one detent 135 connection, or combinations thereof. Focusing on FIGS. 16-18B, a thermoplastic elastomeric material (TPE) 136 is included in the guide feature 126 and is configured to establish a friction fit with the tongue 166.

The TPE 136 optionally is the entire height of the guide feature 126 enabling a compressive force against the tongue 166. Optionally, the TPE 136 engages the protrusion 186 on the tongue 166. The guide feature 126 is optionally sloped or includes a step 196 to heighten a retention force when the tongue 166 (and optionally the protrusion 186) engage the sloped or stepped portion (e.g., by way of step 196). The protrusion 186 is optionally sized to have a height 198 that is slightly greater than the height 200 between the guide feature 126 and the ceiling 125 at the end of the connection portion 130, when the TPE 136 is in a relaxed state (e.g., is not subject to a compressive force by the tongue). In such embodiments, a friction fit is achieved, and optionally also a press-fit, and / or an interference fit.
