Description

Technical field

[0001] The invention relates to portable devices for the controlled dispensing of liquid, gel-like or pasty cosmetic substances, in particular deodorants or perfumes.

[0002] The invention relates specifically to an applicator that can be discreetly attached to women's underwear, particularly bras, and which enables the targeted delivery of the substance to the underarm area through manual or electrical activation. The invention also relates to applicators for the targeted delivery of care or fragrance substances to the intimate area, wherein the device is attached to women's or men's briefs, shorts, or other types of underwear. State of the art

[0003] Popular deodorants in spray or roll-on form are applied directly to the skin, which can lead to staining on clothing and is often not discreet.

[0004] Currently available wearable applicators usually do not offer a specific, targeted approach for the underarm area and are not adaptable to different bra shapes and sizes.

[0005] Furthermore, the substance is administered predominantly manually without taking into account actual sweating behavior. Object of the invention

[0006] The aim of the invention is to provide a compact, discreet and flexibly usable applicator that enables hygienic, targeted and needs-based dispensing of cosmetic substances.

[0007] The applicator should be attachable to women's underwear, and the substance should be released as needed, either by pressure or electrically controlled. Optionally, a moisture indicator should detect perspiration levels to precisely control the dosage. A further aspect of the invention is the provision of an applicator that can be attached to underwear not only in the underarm area but also in the intimate area, in order to deliver targeted care or deodorizing substances there, thus ensuring increased hygiene and freshness. Solution to the task

[0008] The task is solved by a portable applicator that has the following features: • A flat, elastic outer casing measuring approximately 40 mm × 40 mm and with a wall thickness of 3-5 mm, made of skin-friendly silicone or a cotton-elastane blend fabric that is breathable and washable. • Fastening elements consisting of two adjustable straps with length adjustment or Velcro closure, which allow adaptation to different bra models and ensure discreet attachment without noticeable bulging. • Two identical applicators, right and left, to cover both underarm areas. • Replaceable liquid cartridges made of aluminium-coated composite material with a capacity of approximately 3 ml; available as disposable cartridges or refillable versions. • The liquid contains deodorizing and antimicrobial agents that neutralize unpleasant odors and inhibit bacteria without irritating the skin. • A pressure-activated valve opens at 0.3-0.7 bar, whereby 2-3 micro-outlets of approximately 0.2 mm diameter direct the spray jet at an angle of approximately 50-55° to the vertical precisely into the armpit area. • Alternatively, the housing contains a chamber with a pasty or gel-like cream that is selectively released by pressing an area on the housing with a finger. • Optionally, a moisture sensor is integrated into the applicator, enabling sweat detection and triggering the dosage as required via automatic or manual control. • Alternatively, a battery-operated electric nozzle with an on / off switch can be installed, which dispenses the substance electrically at the push of a button. Power is supplied by a rechargeable battery integrated into the housing. • The casing is machine washable and can be cleaned together with the underwear or separately. • The device is designed so that the fastening element is designed for fixation to various types of women's or men's clothing, including bras as well as underpants, briefs or shorts, in order to be able to provide targeted care to both the underarm and intimate areas. Advantages of the invention • Discreet, targeted and hygienic delivery of cosmetic substances • Flexible variants for liquid, gel-like or pasty substances • Adaptable to different bra types thanks to adjustable fastening • Enables disposable and refillable versions of substance cartridges • Comfortable, easy operation, manual or electric • Optional intelligent dosing via moisture indicator • Increased hygiene and freshness, even in the intimate area, through targeted substance release on underwear Example of implementation

[0009] In a preferred embodiment, the housing consists of an elastic silicone with dimensions of 40 × 40 mm and a wall thickness of 3-5 mm. The outer surface is covered with a breathable cotton-elastane blend fabric.

[0010] The liquid cartridge is pressurized, with a volume of approximately 3 ml, and the valve opens at a pressure of 0.5 bar. The spray pattern is dispensed through three micro-openings with a diameter of 0.2 mm, positioned at an angle of 55°.

[0011] The two adjustable straps offer adjustment options for different bra sizes, some with Velcro closures.

[0012] The alternative cream chamber can release the desired amount by pressing the elastic casing with a finger.

[0013] The built-in moisture sensor measures the amount of perspiration and automatically or manually adjusts the dosage when a threshold is exceeded, for example by activating the electric nozzle. The electric nozzle operates with a rechargeable battery integrated into the housing, which is charged via USB. Explanation of the drawing: Fig. Fig. Figure 1 shows a holder according to the invention in the form of a pouch, designed for attachment to a women's bra. The pouch has two laterally arranged clips by means of which it can be easily and securely attached to the strap or the side reinforcement of the bra. An activation button is clearly visible on the front of the pouch, which is operated either manually by finger pressure or electrically to selectively trigger the release of cooling, fragrance, or moisture, depending on the embodiment. The illustration demonstrates the ergonomic shape and functional placement of the components for use under the armpit. Fig. Fig. The image shows the pouch along with its elastic bands, which can be adjusted to fit various types, sizes, and positions of women's bras. The elastic bands are stretchable and automatically adapt to the thickness and position of the bra strap or side support, ensuring a secure and comfortable fit. Both pouches—left and right—are shown as they are positioned under the armpits. Each pouch is equipped with a nozzle that releases a targeted mist of deodorant, cooling gel, or fragrance. Activation is either manual, by pressing the integrated button, or electrical, via a small integrated pump mechanism. The nozzle openings, through which the product is dispensed, are clearly visible and located on the front or side of the pouch. Fig. Fig. This illustration demonstrates the functionality of the device according to the invention in the area below the armpit. The illustration shows the pouch in its activated state, in which mechanical pressure with a finger on the activation button triggers a targeted atomization of the contained substance (e.g., deodorant, coolant, or fragrance). The substance exits through one or more nozzle openings on the pouch and is sprayed directly into the armpit area. The illustration shows the time-limited release process after pressing the button, thus enabling on-demand and discreet application. The device operates purely mechanically, without an external energy source, making it simple, reliable, and reusable. Fig. Fig.Figure 1 shows the filling medium of the holder according to the invention, namely a deodorant or cooling gel in liquid form, which is filled into the pouch. The medium is contained in special packaging under slight pressure, for example in an aluminum bottle or a multi-layered foil ampoule, which ensures a longer shelf life and hygienic dispensing. The packaging is designed so that it can be used either as a single-use unit – after emptying, the empty ampoule is disposed of and replaced with a new one – or so that the pouch can be refilled several times if a reusable version is provided. The refill opening on the pouch can be tightly sealed to prevent leakage of the medium. This allows the device to be used as both a single-use and a reusable system, depending on the design.
