Description

[0001] DESCRIPTION

[0002] Tattoo tool with built-in ink

[0003] OBJECT OF THE INVENTION

[0004] The invention, as the title of this descriptive document states, is a tattooing tool of the cartridge needle type with integrated ink. It is an innovation that offers advantages previously unknown within current techniques.

[0005] TECHNICAL SECTOR

[0006] The present invention falls within the sector of everyday needs, especially in devices for introducing agents into the body or for depositing them on the body, in the classification of other devices for introducing agents into the body.

[0007] STATE OF THE ART

[0008] The present invention arises from the need to address several critical problems in the tattooing process, especially related to ergonomics and the health of the tattoo artist.

[0009] In current practice, the tattoo artist uses cartridge needles to apply the ink and a separate container that holds the ink to reload the needle. This procedure involves a constant and repetitive movement of the hand and arm to the side to reload the ink, which can generate significant muscle overload in the shoulder and arm. In addition, incorrect posture and repetitive movements can cause cervical and back health problems.

[0010] Accordingly, this invention provides a cartridge needle with integrated ink that allows for continuous ink feeding, with the aim of improving operator comfort, reducing muscle strain, and preventing health problems associated with posture and repetitive movements during the tattooing process. Currently, no cartridge needle with integrated ink is known to exist that has structural and constitutive technical characteristics equal to or similar to those described in this specification, as claimed.

[0011] DESCRIPTION OF THE INVENTION

[0012] The object of the present invention is the creation of a tattooing tool with integrated ink that provides a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany this description.

[0013] The present invention is a tattooing tool with integrated ink, which comprises a cartridge needle operatively connected to an ink feed reservoir that continuously supplies ink to the needle, avoiding constant refilling that leads to muscle overload for the tattoo artist, thus improving posture and providing comfort in the creation of tattoos.

[0014] This innovation contributes to a more comfortable and natural posture during work, helps prevent cervical and back health problems, and generally improves working conditions and efficiency in tattoo creation.

[0015] This cartridge needle is beneficial, especially for professional tattoo artists who spend long hours working, as it allows them to maintain concentration on the drawing without interruptions or distractions.

[0016] The inclusion of a neck that connects the ink feed reservoir to the needle in the cartridge needle allows for the continuous supply of ink to the internal area of ​​the needle tip, which helps to maintain a constant flow of ink during the tattooing process, thus improving the accuracy and efficiency in the application of designs.

[0017] The ink reservoir has a refill port on its top, which is fitted with a sealing device, such as a rubber stopper. This stopper has a small central hole that allows air to automatically enter the ink reservoir. This feature prevents the reservoir from depressurizing and ensures the ink flows smoothly to the needle tip, guaranteeing a constant supply of ink during the tattooing process.

[0018] In addition, the needle incorporates a flexible recoil membrane. This membrane acts as an insulator between the wetted area and the back of the drive, preventing the transmission of inks to the cartridge needle and avoiding cross-contamination.

[0019] To use the cartridge needle with integrated ink, the user must first fill the ink reservoir with the desired tattoo ink through the refill hole located on the top of the reservoir. Alternatively, the reservoir can be replaced with another containing the appropriate ink.

[0020] Next, seal the opening with the provided rubber stopper, ensuring that the small central hole allows air to enter to prevent decompression. Once this process is complete, turn on the cartridge needle and begin the tattooing process.

[0021] During this procedure, the ink will be continuously supplied to the needle, eliminating the need for manual refilling, which improves the efficiency and accuracy of the tattoo work.

[0022] EXPLANATION OF THE FIGURES

[0023] To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by a figure in which, for illustrative and non-limiting purposes, the following has been represented.

[0024] Figure 1 shows a perspective view of the cartridge needle with integrated ink.

[0025] Figure 2 shows a schematic section of the tattooing device tip.

[0026] PREFERRED EMBODIMENT OF THE INVENTION.

[0027] The present invention relates to a tattooing tool with integrated ink, characterized by comprising a cartridge needle (1) operatively connected to an ink supply reservoir (2) that continuously supplies ink to the needle (3) disposed at the tip of the cartridge needle (1). This design eliminates the need for constant refilling, thereby reducing muscle strain on the tattoo artist, improving the operator's posture, and providing greater comfort during tattooing.

[0028] In a preferred embodiment, the cartridge needle (1) includes a neck connecting the ink feed reservoir (2) to the needle (3), allowing continuous ink supply to the internal area (2') of the needle tip (3).

[0029] Typically, the ink feed reservoir (2) is provided with a refill hole (4) on its top, which is equipped with a closing means, such as a rubber plug.

[0030] Preferably, this closure means has a small central hole (5) that facilitates the automatic entry of air into the ink feed reservoir (2). This design prevents the reservoir from decompressing and allows the continuous flow of ink to the needle tip.

[0031] Preferably, the cartridge needle (1) incorporates a retractable elastic membrane (6) that acts as an insulator between the wetted area and the back of the needle. This membrane prevents the transmission of ink from inside the cartridge needle (1) into the tool, thus contributing to a more hygienic environment and preventing cross-contamination during the tattooing process. This elastic membrane (6) acts as a sealant while also supporting the needle (3) internally and ensuring its return during operation. As shown in Figure 2, the tool connects the internal ink-filled area (2') to the outside through the needle's passage hole, so that this back-and-forth motion against the elastic membrane (6) facilitates the ink flow.

[0032] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
