Description

  The present invention relates to an impregnated package manufacturing apparatus and a method for manufacturing an impregnated package using the same.

An impregnated package that stores a liquid material and a sheet-like substrate that adsorbs the liquid material in a sealed space of a bag-like container has been used in various fields. For example, a beauty sheet such as a beauty mask in which a sheet-like fiber base formed to have a size enough to cover the face is impregnated with a lotion, a cosmetic liquid, or the like is known. A container-like sheet-like impregnated body in which these cosmetic sheets are sealed with a container that does not heat-seal the main body and the lid is known. (Patent Document 1)
However, the above containers are expensive, and normally, for transporting and storing adsorbents such as cosmetic sheets adsorbing liquid substances, packaging that is sealed with pillow packaging or the like to prevent leakage of skin lotion, cosmetic liquid, etc. An impregnated package in the form is used.
As a method for producing such an impregnated package, a method for producing an impregnated package by sealing a sheet-like substrate impregnated with a liquid in advance in a bag-like container, and a liquid and a sheet-like substrate are separated. There is a method of manufacturing an impregnated package by impregnating a sheet-like substrate with a liquid material after being housed in a bag-like container and sealed.
In the former, since the process of sealing in a bag-like container becomes complicated and productivity is low, the latter method is usually used.
However, in order to impregnate a sheet-like substrate with a liquid material after sealing, conventionally, it has been necessary to squeeze manually by manufacturing a package containing the liquid material.
Therefore, there is a demand for a method that can impregnate the entire sheet-like substrate with a liquid material without relying on human manual work.

As shown in FIG. 1, the manufacturing method of the impregnated package 10 according to the present invention stores a liquid material 12 and a sheet-like substrate 13 that adsorbs the liquid material in a sealed space of a bag-like container 11, and is in a sealed state. In the packing body 1, it is a manufacturing method of the impregnation packing body 10 which makes the liquid substance 12 adsorb | suck to the base | substrate 13, Comprising: The following processes are included.
(1) A conveyor device 20 having a conveyor main body 21 and an endless belt 22 installed on the conveyor main body 21, and is attached to the conveyor main body 21 so as to sandwich the package 1 between the endless belt 22 and the convex portion 31. The package 1 is conveyed from the upstream side to the downstream side of the roller 30 having the concave portion 32.
(2) In the step (1), the roller 30 moves from the downstream side to the upstream side of the packing body 1 while pressing the packing body 1 with the convex portion 31, so that it is liquid in the sealed space of the bag-like container 11. The material 12 is flowed from the downstream side to the upstream side, the liquid material 12 is adsorbed to the base 13, a flow path is formed between the roller 30 and the endless belt 22 by the concave portion 32, and the liquid material 12 and the bag-like container 11 Of the gas in the sealed space, the liquid material 12 and the gas on the upstream side of the roller 30 are released to the downstream side of the roller 30.
In order to enhance the action of the convex portion 31 and the concave portion 32, it is preferable that the liquid material 12 in the bag-like container 11 is arranged in advance on the downstream side in the bag-like container 11. Thereby, the regulation of (a) and (b) of regulation part 41 mentioned above will show the impregnation effect more suitably.

  As described above, the package 1 in which the liquid material 12 and the sheet-like substrate 13 are stored and sealed is sandwiched between the roller 30 and the endless belt 22 from the upstream side of the conveyor device 20, and the conveyor device 20. Move to the downstream side. At this time, the initial contact area where the packing body 1 is sandwiched between the roller 30 and the endless belt 22 is reduced so that the packing body 1 can be smoothly sandwiched between the roller 30 and the endless belt 22 without any trouble. In view of the above, it is preferable to transport the packaging body 1 from the upstream side to the downstream side so that the diagonal direction of the packaging body 1 forms an angle of 0 to 20 ° with respect to the vertical line on the horizontal plane in the axial direction of the roller 30. .

In FIG. 5, the roller 30 moves from the right end to the left end of the packing body 1 when the packing body 1 proceeds in the direction of the thick white arrow (right side). At that time, the concave portion 32 of the roller 30 allows the liquid material 12 to escape in the direction of the left solid arrow, and at the same time, allows the gas to escape in the direction of the left dashed arrow. The liquid material 12 that has escaped to the left side of the package 1 then diffuses in the vertical direction as indicated by the solid line arrow, and impregnates the entire substrate 13. Since the gas escaping to the left end of the package 1 is reversed as indicated by a broken line arrow and returns to the right side, the seal of the package 1 is not broken, and the impregnated package 10 is preferably obtained.

  FIG. 6 shows one embodiment of a sheet-like substrate 13 used in the present invention, an embodiment of a substrate 13 vertically folded, and a package 1 in which the substrate 13 further horizontally folded is sealed in a bag-like container 11. FIG. In FIG. 6, a cosmetic 3D face mask is illustrated as the sheet-like base 13 having the impregnated portion 13 a and the welded portion 13 b. In FIG. 6a, the sheet-like base 13 is vertically folded along the welded portion 13b, in FIG. 6b, the base 13 obtained in FIG. 6a is further vertically folded, and in FIG. 6c, it is obtained in FIG. 6b. A state in which the base 13 is folded sideways and the laterally folded base 13 is stored in the bag-like container 11 is shown. Thereafter, the liquid material 12 is poured into the bag-like container 11 to obtain a package 1 in a sealed state. The impregnated package 10 is preferably formed by storing a plurality of sheet-like base bodies 13 in a bag-like container 11 after being diffracted.
