[0029] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0030] FIGS. 1 and FIGS. 2 are drawings illustrating the schematic configuration of a hygienic disposable pillow cover according to one embodiment of the present invention.

[0031] Referring to FIG. 1 and FIG. 1, a hygienic disposable pillow cover (10) according to one embodiment of the present invention includes a first cover (100), a second cover (200), and an opening (300).

[0032] The first cover (100) is formed in the shape of a square flat plate and provides a basic structure for hygienically protecting the surface where the user's head touches. The first cover (100) secures structural rigidity and is formed of a disposable material, making it easy to replace and providing a hygienic effect that prevents the penetration of bacteria or contaminants.

[0033] The second cover (200) is attached along the edge of the first cover (100) to form an internal space for accommodating a pillow (1) between it and the first cover (100). By forming a sealed structure together with the first cover (100), the second cover (200) protects the pillow (1) from being directly exposed to the external environment and can significantly improve the hygiene of the bedding.

[0034] In one embodiment, the second cover (200) is formed by attaching two covers (210, 220) to the first cover (100) respectively, as shown in FIG. 2, and an opening (300) may be formed in the space between the two covers.

[0035] The opening (300) is formed in the second cover (200) to allow the pillow (1) to be easily inserted or removed into the space between the first cover (100) and the second cover (200). The opening (300) can be designed to increase ease of use while maintaining robustness even with repeated opening and closing.

[0036] A hygienic disposable pillow cover (10) according to one embodiment of the present invention having the configuration described above can be used as a single-use item, thereby reducing the hassle of washing or maintenance, and has the effect of greatly enhancing hygiene in an environment where multiple users use the same pillow (1).

[0038] FIG. 3 is a diagram showing the schematic configuration of a hygienic disposable pillow cover according to another embodiment of the present invention.

[0039] Referring to FIG. 3, a hygienic disposable pillow cover (20) according to another embodiment of the present invention includes a first cover (100), a second cover (200), an opening (300), and a packaging container (400).

[0040] Here, the first cover (100), the second cover (200), and the opening (300) are identical to the components of FIG. 1, so their descriptions will be omitted to avoid duplication of descriptions.

[0041] The packaging container (400) is configured to fold and package multiple pillow covers. The packaging container (400) allows for hygienic storage of the pillow covers and blocks external contaminants, thereby maintaining a hygienic state even during long-term storage. Additionally, the packaging container (400) can be made of a convenient individual packaging structure so that the user can take out and use one pillow cover at a time whenever needed.

[0042] A hygienic disposable pillow cover (20) according to another embodiment of the present invention having the configuration described above can simultaneously ensure hygiene and ease of use, and in particular has the effect of efficiently managing and distributing a number of pillow covers through a packaging container (400).

[0044] FIG. 4 is a drawing showing another configuration of a hygienic disposable pillow cover according to another embodiment of the present invention.

[0045] Referring to FIG. 4, a hygienic disposable pillow cover (30) according to another embodiment of the present invention includes a first cover (100), a second cover (200), an opening (300), and a cover support (500).

[0046] Here, the first cover (100), the second cover (200), and the opening (300) are identical to the components of FIG. 1, so their descriptions will be omitted to avoid duplication of descriptions.

[0047] The cover support member (500) is configured such that a plurality of support modules (600) can be folded together, and after unfolding into a "□" shape, it is positioned along the inner adhesive surface of the first cover (100) and the second cover (200). The cover support member (500) maintains the overall shape of the pillow cover and allows the user to stably support the pillow (1) when inserting it.

[0048] The support module (600) can be folded and unfolded to minimize volume during transport and storage, and can be firmly unfolded during use to prevent the pillow cover from being crushed or deformed.

[0049] A hygienic disposable pillow cover (30) according to another embodiment of the present invention having the configuration described above provides a structural support function beyond simply protecting the pillow (1), thereby improving convenience of use and maintaining shape stability even after prolonged use.

[0051] FIGS. 5 and FIGS. 6 are drawings showing a configuration including a support module according to the present invention.

[0052] Referring to FIGS. 5 and 6, a plurality of support modules (600) are arranged to stably maintain the shape of the pillow cover and include a module body (610), an air transfer channel (620), an air transfer pipe (630), a rotating nozzle part (640), and an expansion induction part (650).

[0053] The module body (610) is positioned along the inner adhesive surfaces of the first cover (100) and the second cover (200) to form the basic structure of the entire support module. The module body (610) provides space for various components related to compressed air to be installed inside and is designed to be continuously connected to other modules.

[0054] The air transfer channel (620) is positioned along the inner side of the module body (610) and conveys compressed air supplied from the compressed air tank. This channel maintains a constant flow of air within the module and induces uniform distribution.

[0055] An air transfer pipe (630) is installed on one side of a module body (610) and transfers compressed air introduced through an air transfer channel (620) to an adjacent module body (610). This allows multiple support modules to continuously share air, thereby enabling the entire cover to expand evenly.

[0056] A plurality of rotating nozzle sections (640) are spaced apart on the front of the module body (610). The rotating nozzle sections (640) rotate and spray compressed air supplied from the air transfer channel (620) to evenly deliver it into the pillow cover. The sprayed air spreads in various directions according to the rotation of the nozzles, causing the entire pillow cover to expand uniformly.

[0057] The expansion induction unit (650) is installed on the upper side of the module body (610) and helps to facilitate smooth expansion by repeatedly lifting the second cover (200). The expansion induction unit (650) is a key component that increases the efficiency of air injection inside the cover and induces the pillow cover to inflate smoothly.

[0058] The support module (600) having the configuration described above has the effect of maintaining the hygienic disposable pillow cover (30) in a stable form and providing a ready state for immediate use by the user by integrally performing compressed air delivery, injection, and expansion induction functions beyond simply providing structural support.

[0060] FIGS. 7 and FIGS. 8 are drawings showing a rotating nozzle part according to the present invention.

[0061] Referring to FIG. 5, the rotary nozzle part (640) includes a nozzle groove (641), a rotary transfer pipe (642), a nozzle head (643), a shear inclined surface (644), and a spray nozzle (645).

[0062] It is placed in a nozzle groove (641) formed on the front of the module body (610). The nozzle groove (641) provides a space to accommodate a rotational transmission pipe (642) and a nozzle head (643), and functions as a support structure that enables stable rotation during air injection.

[0063] The rotary transfer tube (642) is installed such that its rear end is connected to the air transfer channel (620) and its front end is exposed to the nozzle groove (641). The rotary transfer tube (642) receives compressed air from the air transfer channel (620) and transfers it toward the nozzle head (643), and is designed to rotate on its own.

[0064] The nozzle head (643) is installed at the front end of the rotary transmission pipe (642). The nozzle head (643) is a key component that controls the direction of air injection, and the front end forms an inclined surface structure to induce the dispersion of airflow.

[0065] The shear slope (644) is formed at the front of the nozzle head (643) and serves to induce rotational force when air is ejected. The shear slope (644) enables efficient rotation by controlling the direction and pressure of the air through the angle of inclination.

[0066] The injection nozzle (645) is installed on the shear slope (644) and injects compressed air supplied through the rotary transfer pipe (642) in a diagonal direction. The reaction generated during this injection process induces rotation of the nozzle head (643), and simultaneously with the rotation, compressed air is injected into the internal space of the pillow cover.

[0067] The rotating nozzle part (640) having the configuration described above has the effect of evenly dispersing air by delivering compressed air in a rotating spray manner and inducing uniform expansion inside the pillow cover. Therefore, the hygienic disposable pillow cover (30) according to one embodiment of the present invention can provide a comfortable usage environment for the user by stably inflating the entire internal space.

[0069] The rotating nozzle part (640) having the configuration described above may further include a shaft moving groove (646).

[0070] The shaft movement groove (646) is formed along the nozzle head (643) and the shear slope (644) so ​​that the lower end of the lifting guide shaft (651) can be seated and moved. This shaft movement groove (646) extends in a circular ring shape in the width direction of the nozzle head (643) to provide a path through which the lifting guide shaft (651) can move smoothly.

[0071] The lifting guide shaft (651) moves along the shaft movement groove (646) and converts the rotational motion of the rotating nozzle part (640) into an up-and-down lifting motion. During this process, the lifting guide shaft (651) periodically repeats the up-and-down motion according to the rotation of the nozzle head (643), and this motion is transmitted to the deployment guide wing (652) so that the operation of lifting the second cover (200) is continuously performed.

[0072] The circular ring structure of the shaft movement groove (646) guides the lifting guide shaft (651) to move stably along a limited path, thereby preventing imbalance or abnormal vibration that may occur during the expansion process. Thus, the pillow cover can expand smoothly and uniformly.

[0073] The interlocking structure of the rotating nozzle part (640) and the shaft moving groove (646) having the configuration described above has the effect of efficiently combining the injection force of compressed air and mechanical motion conversion to automate and stabilize the expansion process of the pillow cover. Accordingly, the hygienic disposable pillow cover (30) according to one embodiment of the present invention helps the user maintain a uniform expansion state without separate manual operation.

[0075] FIG. 9 is a drawing showing an expansion induction part according to the present invention.

[0076] Referring to FIG. 9, the expansion guide (650) includes a lifting guide shaft (651) and a deployment guide wing (652).

[0077] The expansion guide (650) has the function of helping the second cover (200) to be repeatedly lifted up so that the expansion inside the pillow cover is smooth. The expansion guide (650) includes a lifting guide shaft (651) and an expansion guide wing (652).

[0078] The lifting guide shaft (651) is installed by penetrating the module body (610) in an upward and downward vertical direction. The lower end of the lifting guide shaft (651) is seated on the nozzle head (643) and moves along its circumference when the nozzle head (643) rotates. During this process, the lifting guide shaft (651) performs a repetitive lifting motion, moving upward by rotational force and moving downward along the shear slope (644). This motion converts simple rotational operation into vertical motion, forming a basis for the second cover (200) to be lifted regularly.

[0079] The deployment guide wing (652) is formed in a flat shape, and its rear end is rotatably connected to the upper rear end of the module body (610). The front end of the deployment guide wing (652) is supported by the upper end of the lifting guide shaft (651). Therefore, whenever the lifting guide shaft (651) moves up and down, the front end of the deployment guide wing (652) moves repeatedly in the up and down direction. This causes the second cover (200) to be repeatedly lifted, and air can be effectively filled inside the pillow cover.

[0080] The expansion induction part (650) having the configuration described above enables uniform expansion that is difficult to achieve with simple air injection alone, and assists the second cover (200) to unfold naturally, thereby having the effect of the pillow cover expanding smoothly without being crushed. Accordingly, the hygienic disposable pillow cover (30) according to one embodiment of the present invention can maximize user convenience by ensuring stability and reliability in the expansion process.

[0082] The embodiments described above are for illustrative purposes only, and those skilled in the art will understand that the embodiments described above can be easily modified into other specific forms without altering the technical concept or essential features of the embodiments described above. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.
