Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for applying a primarily viscous insertion lubricant to a sanitary tampon.

In order to facilitate insertion of a sanitary tampon into the vagina, various inventions and ideas have been made regarding applying an insertion lubricant to the insertion tip of the tampon, but in all cases, the state of the application is as follows: It is applied to the entire surface of the insertion tip of the tampon, which is often the entire hemisphere.

Applying the lubricant to the entire surface of the tip of the tampon makes insertion easier, but since the applied lubricant covers the entire surface of the most important tip of the absorbent material, it affects the suction speed of the tampon, especially the initial speed and suction speed. This results in a decrease in volume, which leads to leakage, reducing the effectiveness of the tampon. In view of this point, the present invention has succeeded in providing a coating method that facilitates insertion and does not impede suction speed or amount.

In other words, the invention relates to a method and apparatus that can be mass-produced and applied to the shoulder of a tampon in a donut ring shape, that is, a hazel shape, except for the central part of the insertion tip of the tampon. If the present invention is explained below with reference to the drawings, first
The figure is a perspective view of the overall appearance of the applicator according to the present invention, in which 1 is a tampon lubricant, 2 is a container containing the lubricant 1,
1a is a lubricant in which an appropriate amount of lubricant 1 has been extruded from a container 2, and lb, IC, and ld are all in a state in which lubricant 1 is carried and adhered to and diffused onto each roller.

3, 4, and 5 are rollers that rotate in the directions of arrows shown in the figure.

6 is a conveyor that conveys the molded tampon 12 to the illustrated position of rollers 4 and 5; 7 is a rotatable guide pin; 8 is a fixed chute; 9 is a rotating machine that transports the tampon 12 while stably rotating; 10 is the pulley, and 11 is the round belt.

FIG. 2 is a schematic view seen from the left side of FIG. 1, showing the state in which the tampon lubricant according to the present invention is applied in an annular manner to the donut gate. 4' is the part where the roller 4 and the tampon 12 are in contact with each other.

Similarly, 5' is a portion where the roller 5 and tampon 12 are in contact with each other. FIG. 3 is an external view of a completed lubricated tongue 13 according to the present invention, and 13 in FIG. 2 is taken out. To describe the order in which the lubricant 1 is applied to the tongue horn 12, the lubricant 1 is automatically and continuously extruded from the container 2 in an appropriate amount to become the lubricant 1a, and the lubricant 1a adheres to the roller 3 and is applied by the rotation of the roller 3. The lubricant 1b is spread over the entire surface of the roller 3 and becomes 1b, and at the same time, since the roller 4 is in contact with the roller 3 as shown in the figure and is rotating in the opposite direction to the roller 3, the lubricant 1b is reversed and attached to and spread over the entire surface of the roller 4. This becomes lubricant 1C.

Similarly, the lubricant 1C contacts the roller 4 and is reversed by the roller 5, which rotates in the opposite direction, to become the lubricant 1d. In this way, at the same time as the lubricant 1 is adhered and diffused to the rollers 4 and 5 by the combination of rotating rollers to become the lubricants 1C and 1d, a molded tandem foam is placed at the position where the rollers 4 and 5 come into contact. 12, a conveyor 6 is provided which transports the formed tongue 12 in the direction of the rollers 4, 5, sandwiching it between the guide pins 7. As shown in the figure, before and after the tongue horn 12 reaches the rollers 4 and 5,
The rotary machine 9 stabilizes the tanhong 12, and the flow rate is 0.
By rotating the round belt 11 with the rotation of , one tongue horn itself rotates, that is, rotates on its own axis. Due to the fact that the rotation of the tongue horn is perpendicular to the rotation direction of the rollers 4 and 5, and the indentations created by the contact points of the rollers 4 and 5, the coating is applied in a donut ring shape except for the center of the head of the tongue horn. As described above, an ideal menstrual tongue phone that is easy to insert without reducing suction speed or amount has been realized.

By successfully applying the lubricant in mass production, we will be able to provide a sanitary pad that is easy to use and provides peace of mind to the user.

[Brief explanation of the drawing]

FIG. 1 is an overall perspective view of a coating device related to the coating method of the present invention, and FIG. 2 is a schematic side view of FIG. 1, showing a state in which lubricant is applied in an annular shape.

Claims (1)

[Claims] 1. In applying a lubricant for inserting a viscous sanitary tampon, the lubricant is diffused onto the surface of the rollers by a vertical combination of rollers, and the lubricant is spread at right angles to the direction of rotation of these rollers. By rotating the tampon itself in the direction of rotation, and moving the tampon in the lateral flow direction while positioning the center of the head of the rotating tampon in the concave part of the joint of the roller, the tampon is inserted into the insertion tip excluding the central part of the leading edge of the tampon head. A method of applying lubricant in a donut ring. 2. In a device for applying lubricant for inserting viscous sanitary tampons, three rollers 3, 4, and 5 were rotated vertically in contact with each other, and lubricant 1 was placed on top of roller 3, leaving a small gap at the bottom. A conveyor 6 having a guide pin 7 is provided on a fixed chute 8 in which the lubricant container 2 is installed and the tip of the tampon is transferred perpendicularly to the position where the rollers 4 and 5 contact each other. Pulley 1 for rotating each sandwiched tampon from the top
0 and a rotating machine 9 having a round belt 11, the lubricant is applied in a donut ring shape to the insertion tip of the tampon except for the center of the tip of the head of the tampon. 1. A tampon lubricant application device according to the method described in 1.
