DETAILED DESCRIPTION OF THE INVENTION
[0016] A holder according to the present disclosure is specifically designed for a powered driven personal care item, and serves the purpose of securely holding the personal care item in place during a charging process. The personal care item can be placed on and charged through a charging unit to which the holder is attachable. The holder is designed to hold the powered driven personal care item securely in place, and ensures that the personal care item remains stable and properly aligned on the charging unit during charging, minimizing the risk of accidental displacement or damage.
[0017] The holder is unitarily formed as a single piece, and manufactured as a singular, integrated structure. A single, integrated structure may ensure structural integrity and durability of the holder. The unitary construction also simplifies the attachment process of the holder to the charging unit, making it user-friendly and efficient. Further, the unitary formation of the holder as a single piece contributes to manufacturing efficiency. It simplifies the production process and reduces manufacturing costs, while ensuring a consistent and reliable product.
[0018] The holder's design ensures a secure and stable connection between the personal care item and the charging unit. The holder prevents the personal care item from shifting or falling off during the charging process, thereby providing protection against accidental impacts or falls reducing the risk of damage.
[0019] The holder according to the present disclosure offers advantages such as enhanced stability for the personal care item during charging, ease of use, protection of the personal care item, and manufacturing efficiency. By combining these features, the holder provides an improved charging experience for personal care items and ensures their secure positioning and efficient recharging.
[0020] In order to hold the powered driven personal care item properly in place during charging, the holder may comprise a substantially circular ring-like structure into which the powered driven personal care item is at least partially insertable. To facilitate easy attachment of the holder to the charging unit, the holder may further comprise an attachment section for attaching the holder to the charging unit. Such attachment section may comprise an adhesive, for example an adhesive tape, for attaching the holder to the charging unit. To conveniently accommodate a charging cable or a power plug, the attachment section may comprise a recess into which such charging cable or a power plug can be inserted. The substantially circular ring-like structure may be connected with the attachment section via a bridge. Such configuration of a holder provides a simple structure, which is easy to manufacture, attach and clean.
[0021] Also, such holder is compatible with various personal care items. The holder's design allows for versatility, being able to accommodate products or items of different shapes and sizes. For example, the personal care item may be an electrical oral care implement, e.g. an electrical toothbrush, flosser, toothpick or the like, an electrical shaver or razor, a hair trimmer, epilator, electric facial cleansing brush, an electrical massager, or an electrical nail care device.
[0022] The holder can be attached to the charging unit by an adhesive strip or tape. Such strips may have adhesive properties on both sides and can be pre-cut to the desired shape and size. One side of the strip adheres to the holder, while the other side attaches to the surface of the charging unit. Adhesive strips or tapes may provide a convenient attachment method without leaving residue or causing damage to the charging unit.
[0023] Alternatively, the holder may be attached to the charging unit by means of glue or other adhesive material to create a bond between the surface of the holder and the surface of the charging unit. The glue or adhesive selected is preferably compatible with both, the material from which the holder is made and the surface material of the charging unit.
[0024] The attachment section may comprise gluing spots for gluing the holder to the charging unit. Such gluing spots provide designated areas where adhesive/glue can be applied. The spots provide clear guidance for the application of adhesive/glue, eliminating the need for precise application or guesswork. This feature enhances the user-friendliness of the holder and allows for efficient and convenient attachment.
[0025] The glue/adhesive material may be selected from the following list: Cyanoacrylates, polyurethane adhesives, and epoxy resins.
[0026] Attaching the holder to the charging unit by gluing may comprise the following steps: [0027] Surface preparation to ensure that both, the surface of the attachment section of the holder and the contact surface of the charging unit are clean and free from dirt, dust, oils or the like, to promote improved adhesion. [0028] Adhesive application by applying an appropriate adhesive to either the surface of the attachment section of the holder or the contact surface of the charging unit. [0029] Bonding by positioning the attachment section of the holder onto the desired location on the charging unit, thereby ensuring proper alignment and contact, optionally applying appropriate pressure to create a strong bond between the holder and the charging unit. [0030] Curing the adhesive, optionally by maintaining pressure on the bonded surfaces for a specific period of time.
[0031] By gluing the holder to the charging unit, a secure attachment can be provided. The adhesive can create a strong bond between the holder and the charger, ensuring that the holder remains securely in place during usage of the personal care item.
[0032] The holder may be made from thermoplastic material that offers durability, and resistance to tampering.
[0033] Thermoplastic materials are known for their cost-effectiveness in manufacturing processes. They can be easily molded and formed using techniques such as injection molding, which enables high-volume production at relatively low costs. This may make a thermoplastic holders an economical choice for mass production.
[0034] Further, thermoplastics offer a wide range of design possibilities due to their ability to be molded into various shapes and sizes. This flexibility allows for the creation of holders with intricate or customized designs, accommodating different personal care item shapes and sizes. Manufacturers can easily modify and iterate on the design to meet specific requirements or incorporate additional features.
[0035] Also, thermoplastics are typically lightweight materials, making them suitable for applications where weight reduction is desirable. A lighter holder contributes to a more comfortable user experience, particularly for handheld personal care items. Additionally, lightweight materials can reduce shipping costs and environmental impact during transportation.
[0036] Moreover, the thermoplastic material may exhibit excellent durability and resistance to impact, chemicals, and moisture. This ensures that the holder can withstand regular use and environmental conditions, like use in wet conditions, without significant degradation, prolonging its lifespan. Moreover, the thermoplastic material can be engineered to have specific properties, such as antimicrobial properties, enhancing the performance and longevity of the holder. Also, such holder made form thermoplastic material is generally easy to clean, as it can be wiped down or rinsed with water. The non-porous nature of thermoplastics minimizes the absorption of dirt, grime, or bacteria, ensuring hygienic use of the holder for personal care items. If the thermoplastic holder has a non-slip surface, this may provide a comfortable grip for users when handling the holder, enhancing user experience, especially for personal care items that are used with wet hands or in wet environments.
[0037] Furthermore, thermoplastics offer a wide range of color options, allowing manufacturers to create visually appealing holders. The ability to incorporate different colors, finishes, or textures enhances the overall aesthetic appeal of the holder, aligning with consumer preferences, the outer appearance of the personal care item to be stored and/or the charging unit, or brand identity.
[0038] For example, the holder may be made from acrylonitrile butadiene styrene (ABS) or acrylonitrile styrene acrylate (ASA). ABS and ASA may provide the holder with improved durability and toughness. Such materials can withstand impacts, shocks, and mechanical stresses without significant deformation or damage. This makes ABS and ASA holders suitable for demanding environments or situations where the holder may be subject to rough handling or accidental drops, like in a retail environment or stores. Also, ABS and ASA materials may provide the holder with improved dimensional stability with low levels of shrinkage during a molding process. This means that ABS and ASA holders are less prone to warping or distortion over time, ensuring long lasting functionality.
[0039] Alternatively, the holder may be made from a thermoplastic elastomeric material (TPE e.g. TPA, TPC, TPO, TPS, TPV), ethylene-vinyl acetate (EVA), or Nitrile Butadiene Rubber (NBR).
[0040] The holder may be made from a material, e.g. thermoplastic material, having a Shore D hardness from about 40 to about 90, or a Shore D hardness from about 50 to about 80. A holder made from a material having a Shore D hardness from about 40 to about 90 possesses a moderate level of hardness. This range strikes a balance between softness and rigidity, providing the holder with desirable properties for its intended use. It offers sufficient flexibility, durability, and resilience and can conform to the shape and contours of different charging units maintaining its shape and providing a secure attachment.
[0041] A charging system according to the present disclosure comprises a holder as discussed herein, and a charging unit. The charging unit may comprise a substantially flat surface onto which the powered personal care item can be placed.
[0042] Such flat surface is generally easy to clean and maintain. It can be wiped down or cleaned with mild disinfectants, ensuring hygiene and preventing the buildup of dirt or bacteria, promoting a clean and hygienic charging environment for the personal care item. Such flat surface of the charging unit also provides a simple and intuitive solution for positioning the personal care item for charging. Users can easily place the item on the flat surface without the need for complex mechanisms or clamps. This enhances the overall user experience and convenience. Moreover, a charging unit with a flat surface is generally compatible with a wide range of items, e.g. toothbrush models having handles of different thicknesses or shapes. It can accommodate personal care items of different sizes, shapes, and brands, making it versatile and suitable for various users. This eliminates the need for multiple charging units for different items, e.g. toothbrush models, providing convenience and flexibility. Since the flat surface design does not rely on specific structural means to hold an item/toothbrush in place, it can accommodate items/toothbrushes with different charging mechanisms or connector types.
[0043] Further, the charging unit may have the form of a substantially flat disk. A charging unit in the form of a disk with a flat surface provides a sleek and minimalistic design, adding to the overall visual appeal of the system or e.g. a toothbrush charging setup. It can complement modern bathroom aesthetics and contribute to a clean and organized appearance.
[0044] The charging unit may comprise a permanent magnet or a magnetizable element for magnetic interaction with the powered driven personal care item. The presence of a permanent magnet or magnetizable element in the charging unit enables magnetic interaction with the powered driven personal care item (such as an electrical toothbrush). This magnetic interaction provides an attachment mechanism, ensuring that the personal care item remains in place and correctly positioned during the charging process. It minimizes the risk of accidental displacement, enhancing the stability and reliability of the charging connection. Magnetic attachment also offers a user-friendly and convenient solution. Users can effortlessly position the personal care item on the charging unit, and the magnetic force takes care of correct positioning/final adjustment. This eliminates the need for complex clamps or pins, simplifying the charging process and improving overall user experience. Without physical clamps or pins, there are fewer areas for dust, debris, or moisture to accumulate, making the charging unit easier to clean and maintain. The magnetic interaction between the charging unit and the personal care item helps in aligning the item correctly for charging. The magnetic force guides and holds the item in the proper position, ensuring proper electrical contact between the charging unit and the item's charging contacts. This alignment assistance reduces the chances of misalignment, which could otherwise result in incomplete or inefficient charging. The use of a permanent magnet or magnetizable element in the charging unit allows for compatibility with a wide range of personal care items. Different shapes and sizes of personal care items can be accommodated by adjusting the positioning on the charging unit, leveraging the magnetic interaction. This versatility ensures that the charging unit can be used with various models or brands of personal care items, providing convenience and flexibility for users.
[0045] When the attachment section of the holder is attached to the charging unit, a spacing between the charging unit and the substantially circular ring-like structure of the holder may be provided. The spacing between the charging unit and the substantially circular ring-like structure creates a physical gap or distance. The spacing between the charging unit/it's upper flat surface and the holder's circular ring-like structure allows for easier cleaning and maintenance. It provides access to clean the charging unit's surface, remove debris or dust particles, and wipe down the holder without obstruction. The spacing between the charging unit and the holder's circular ring-like structure helps also ensures that the ring-like structure of the holder does not impede the functionality or operation of the charging unit. This prevents any potential interference with charging contacts, electrical connections, or other components of the charging unit, ensuring smooth and uninterrupted charging. Also, the presence of spacing between the charging unit and the holder's circular ring-like structure can contribute to the visual appeal of the overall design. The gap creates a distinct separation between the two components, adding an aesthetic element to the charging setup. It can create an appealing contrast or highlight the individual characteristics of the charging unit and the holder, enhancing the overall aesthetics of the charging system.
[0046] The charging unit may have a substantially circular cross-sectional shape with a diameter, and the substantially circular ring-like structure of the holder has a diameter which is smaller than the diameter of the charging unit. The smaller diameter of the holder's ring-like structure can ensure a secure fit of the personal care item within the charging system, minimizing the risk of accidental detachment or displacement. This secure fit provides added protection for the personal care item, reducing the likelihood of damage caused by falling or shifting during charging. Also, the difference in diameter allows for precise alignment of the personal care item on the charging unit. The smaller diameter of the holder's ring-like structure ensures that the personal care item is properly centered and positioned within the charging system/on the charging unit. This alignment can promote optimal electrical contact between the charging unit and the personal care item's charging contacts, ensuring efficient and effective recharging.
[0047] A unit according to the present disclosure, for example a display or touch-and-feel unit, comprises a charging system as discussed herein, and a powered driven personal care item.
