Description

  The present invention relates to a face mask package that can be impregnated with a high-viscosity cosmetic pack and can be easily deployed during use.

Face masks are used to obtain a beauty effect by sticking a sheet base material that has been infiltrated with cosmetic ingredients such as cosmetic liquid and lotion so that it is in close contact with the entire face. After the sheet base material was folded in the vertical and horizontal directions, it was inserted into a packaging bag made of a laminate film made of polyethylene or the like, and then the cosmetic liquid for packing having a viscosity of about 3 Pa · sec (Pascal · second) was dried. A face mask package is manufactured by impregnating a sheet base material and further heat-sealing and sealing the upper part of the packaging bag (see Patent Document 1). The face mask packaging body can impregnate a cellulosic nonwoven fabric or the like having a basis weight of 60 g / m ² or less into a sheet base material with a cosmetic solution for packs having a viscosity of less than 3.5 Pa · sec at the maximum. It is impossible to uniformly impregnate the sheet base material with the viscosity of the following reasons for the following reasons.

  The lower portion and both lateral ends of the packaging bag made of the laminated film are heat-sealed, and an insertion port for inserting the folded sheet base is formed in the upper portion of the packaging bag. In order to insert the sheet base material automatically folded by the automatic packaging machine from the insertion port, the lateral width of the packaging bag is formed larger than the lateral width of the sheet base material, and the automatic packaging machine By inserting both lateral end portions into the inside, an elliptical insertion port is formed, and the folded sheet base material can be easily inserted into the insertion port. After that, the pack cosmetic liquid is injected from the insertion port. Since the space is formed on both the left and right sides of the sheet base material inserted and folded into the packaging bag, the injected pack cosmetic liquid is injected into the space. First flow. If a pack cosmetic liquid having a high viscosity, for example, 3.5 Pa · sec or more is injected, the pack cosmetic liquid flowing into the space only comes into contact with a part of the folded sheet base material. It is known that due to the viscosity, the entire sheet base material is not uniformly impregnated and unevenness occurs.

By the way, the following patent documents are known as prior art documents related to the face mask packaged body stored in the packaging bag in a state of being wound up in a rod shape.
The face mask for beauty is half-folded vertically or horizontally, and this half-folded face mask is formed into a roll-shaped face mask from one side to the other, and this is formed into a thin cylindrical packaging bag. Put in and store. In addition, when using this cosmetic face mask, remove it from the thin cylindrical packaging bag, pour the lotion into the face mask wound in this roll shape, remove the roll after it has become well wet, There has been proposed a cosmetic face mask to be used after returning to a folded face mask and then returning to a face mask opened on one side (see Patent Document 2).

  In addition, as another face mask packaging body, a face mask folded in half is further folded in half, and the folded face mask sheet is rolled up from the tip of the head to a substantially cylindrical stick-like body to give a skin care lotion. There has been proposed a portable face mask pack in which an impregnated face mask is sealed with an aluminum laminate sheet (see Patent Document 3). Patent Document 3 does not suggest or describe that a skin care lotion to be impregnated in the portable face mask pack can be used with a high viscosity.

JP 2004-002253 A Japanese Patent Laid-Open No. 2008-12585 JP 10-081612 A

The face mask package of Patent Document 1 is uniformly impregnated with a sheet base material when a high-viscosity pack cosmetic liquid is injected into a packaging bag in order to meet the needs of users who expect high cosmetic effects and maintainability. Therefore, it was difficult to produce a face mask packaging body impregnated with a high-viscosity cosmetic liquid for packs.
The cosmetic face mask of Patent Document 2 takes out a roll-shaped face mask from a packaging bag, infuses it with skin lotion, impregnates it, and then unfolds the roll-shaped face mask on one side. It is to be used after. Therefore, the cosmetic face mask has the trouble of continuously injecting and impregnating lotion, and unfolding operation to unfold the face mask on one side, and in particular, the unfolding operation is not easy. Have.

  The stick-shaped body of the face mask of Patent Document 3 is folded in half and then folded in half, and the folded face mask sheet is rolled up from the head tip into a substantially cylindrical stick shape, and the skin care lotion Therefore, when using it, tear the sealed packaging bag, take out the stick-shaped body by hand, rewind the face mask rolled up with both hands on a flat surface, and fold it twice in half. The face mask needs to be unfolded and opened on one side, the hands get dirty with a skin care lotion, it takes a long time to unfold the face mask, and the unfolding operation is very troublesome. doing.

  Therefore, the object of the present invention is to impregnate a high-viscosity pack cosmetic liquid in order to exhibit and maintain a high cosmetic effect, and the development time until the face mask is developed on one side is short and the deployment operation can be easily performed. It is to provide a face mask package.

In view of the above-mentioned problems, the present inventors have intensively studied and, as a result, have completed the face mask packaging body of the present invention.
That is, in order to solve the above-mentioned problem, the face mask package of the invention according to claim 1 is folded so that a face mask in which a base sheet formed in a face shape is impregnated with a cosmetic liquid for packs can be unfolded during use. A face mask packaging body in which a rod-shaped body rolled up in a packaging bag is packaged, and the base sheet is provided with tabs protruding outward from the side edges of the cheek at both ends of the face-shaped head The base sheet is folded in the Z direction in the horizontal direction and rolled up from the bottom of the base sheet folded in the vertical direction to form a rod-like body, and the tip of the knob portion protrudes from both ends of the rod-like body It is characterized by that.
Similarly, in the face mask package of the invention according to claim 2, the viscosity of the cosmetic liquid for pack is 3.5 to 12.0 Pa · sec. .
The face mask package of the invention according to claim 3 is characterized in that the tip of the knob has a mark on either the left side or the right side.
In the face mask package of the invention according to claim 4, the knob is provided with a fold line at the base, and the length reaches the position of the corner of the eye when folded at the fold line. It is characterized by.
The face mask package of the invention according to claim 5 is characterized in that the packaging bag is a laminated sheet packaging bag.

The face mask packaging body of the present invention is omnidirectional from the center of the rod-shaped body to the outside by wrapping the rod-shaped body formed by winding up from the bottom of the base sheet folded in the vertical direction with a packaging bag. Since the pack cosmetic liquid permeates in a uniform state, the face mask can be uniformly impregnated with the high-viscosity pack cosmetic liquid.
The face mask of the face mask packaging body of the present invention has a knob portion protruding outward from the side end of the cheek portion at both ends of the face-shaped head, and the tip portion of the knob portion from both ends of the rod-shaped body. Is protruding, it is easy to take out the tip of the knob from the packaging bag.
In addition, since the face mask is folded in the Z direction in the lateral direction, if a lateral tensile force is applied to both ends of the head of the face shape, it works much larger than the adhesive force. Operation to expand in the horizontal direction is easy.
Furthermore, since it is folded in the vertical direction and wound up from the lower part, deployment is promoted by the weight of the face mask during the above operation.
Furthermore, since the knob | pick part of a face mask package is the length which reaches | attains the position of the corner of an eye when it bends with a fold line, it can make it easy to impregnate the cosmetic liquid for packs in the corner of an eye.

It is a top view of the base material sheet for face masks of the whole face. It is explanatory drawing which shows the process after folding a base material sheet, accommodating the rod-shaped body created by winding up in a rod shape in a packaging bag, and forming a face mask packaging body. It is a figure showing the impregnation state of the cosmetic liquid of the developed face mask of Examples 1-3. It is a figure showing the impregnation state of the cosmetic liquid of the developed face mask of Comparative Examples 1-3.

Hereinafter, an example of an embodiment of the face mask package of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a face-shaped base sheet.
The face mask 1 ′ is obtained by impregnating a base sheet 1 formed in a face shape with a pack cosmetic liquid. As the material of the base sheet 1, a cellulose nonwoven fabric, a woven fabric, or the like is used. Further, the basis weight is preferably 30 to 80 g / m ² . The head portion of the face-shaped base sheet 1 is provided with a knob portion protruding outward from the side edge of the cheek portion, and the knob portion 2 whose shape is a semicircular corner shape is oblique. It is formed to extend outward. A cut 3 is formed at the tip of the right knob 2, and it can be identified that the knob 2 is held by the left hand. Reference numeral 4 denotes an inverted U-shaped separation line provided at the position of the eye of the face, and the eyelid part 6 is bent downward as shown on the left side by a folding line 5. Like the left side, the right side has the eyelid part 6 bent downward, and when the face mask 1 'is worn on the face, the eyelid part 6 is placed on the outside so that the fit is good. It becomes. Therefore, by setting the notch 3 as a mark, the user can grasp the sticking part 2 with the notch 3 with the left hand and stick it to the outside so that the eyelid part 6 becomes outside.
In the example of the above-described embodiment, the example in which the eyelid part 6 is bent downward along the fold line 5 is shown, but a hole may be provided in the same manner as the mouth without providing the eyelid part 6.

  Reference numeral 8 denotes a fold line (for example, a discontinuous slit line) provided at the base of the knob 2. After the face mask 1 ′ is attached to the face, the knob 2 is placed at the position of the fold line 8. Bend and paste the knob 2 over the corner of the eye. Since the picked portion 2 that is affixed in layers is located at the corner of the corner of the eye, it is easy to focus on supplying the pack cosmetic liquid to the corner of the corner where the eyelid is conspicuous. The length of the knob 2 is preferably such that when the knob 2 is bent along the fold line 8, the length of the semicircular square shape at the tip reaches the position of the corner of the eye.

  Reference numerals 9 and 10 denote folding lines that divide the lateral width of the base sheet 1 into approximately three parts, reference numeral 11 denotes a folding line provided substantially orthogonal to the folding lines 9 and 10, and the vertical width of the base sheet 1. Is roughly divided into two. In addition, although the said fold line 9-11 showed the position folded by a dashed-dotted line for description, in fact, since a folding machine automatically folds the base material sheet 1, the fold lines 9- on the base material sheet 1 are shown. 11 is not displayed.

The above-described knob portion 2 is a square shape with a semicircular tip, and is provided so that the face mask 1 'can be easily picked and the folded face mask 1' can be easily developed. And the notch 13 is formed in the front-end | tip of the right knob part 2, and the notch 3 is provided in order to identify that the knob part 2 is hold | gripped with a left hand. The fold line 8 is provided for attaching the face mask 1 'to the face, bending the knob 2 at the position of the fold line 8, and overlapping the knob 2 to the position of the corner of the eye. .
As described above, when the hole is provided without providing the eyelid portion 6, it is not necessary to provide the cut.

  From the above, the configuration of the face mask knob 2 is different from that of the conventional face mask, and the knob 2 is a face-shaped base sheet at both ends of the head of the face-shaped base sheet 1. 1 is different from the first embodiment in that it protrudes outward from the side end of 1 and a fold line 8 (the fold line 8 will be described later, see FIG. 1) at the base of the knob 2. .

FIG. 2 is an explanatory diagram illustrating a process from when the base sheet is folded and then rolled up into a rod shape to accommodate the rod-shaped body in a packaging bag to manufacture a face mask package.
The process of folding the face-shaped base sheet 1 shown in FIG. 2a along the fold line and storing it in the packaging bag shown in FIG. 2g will be described below in order.

  First, both eyelid parts 6 in FIG. 2a are bent at a fold line 5, and then the right side portion including the knob part 2 of the base sheet 1 is bent at a fold line 10 as shown in FIG. 2b, as shown in FIG. 2c. Thus, the base sheet 1 is turned over. As shown in FIG. 2d, the left side portion including the knob 2 of the base sheet 1 is folded along the folding line 9, and the base sheet 1 is folded in the lateral direction by Z-folding. Next, as shown in FIG. 2e, the base sheet 1 is turned upside down and folded in a vertical direction with a fold line 11 intersecting with the fold lines 9, 10, and then folded as shown in FIG. 2f. The layers are densely wound up from the lower end to the top so that no space is created between the wound layers. And the both knob | pick part 2 of the state protruded from the both ends of the rod-shaped body 13 is formed.

  The packaging bag 14 has an aluminum laminate sheet as shown in FIG. 2g, preferably a multilayer laminate sheet made of a synthetic resin layer and an aluminum layer. The packaging bag is preferably a stick-shaped bag because it is suitable for storing a rod-like body, is not bulky, and is easy to carry. By pressing the lateral end portion inward to form a circular insertion port, the rod-shaped rod-shaped body 13 having no space between the layers can be easily inserted into the insertion port. The dense rod-shaped body 13 spreads outward until it sticks to the inner wall of the packaging bag 14, and as a result, a space is formed at the center of the rod-shaped body 13. The pack cosmetic liquid is inserted into the pack. When injected from the mouth, the pack cosmetic liquid flows into the space at the center of the rod-shaped body 13. Thus, the space is filled with the face mask by sealing the upper portion of the packaging bag 14 in this state. The package 20 is obtained, and a reference numeral 16 denotes an opening for opening, which is provided under the seal 15 '.

As described above, the pack cosmetic liquid flows into the space of the central portion of the rod-shaped body 13 and is filled, so that the omnidirectionally outward from the central portion of the base sheet 1 wound in a rod shape. Even if a high-viscosity pack cosmetic liquid having a viscosity of 3.5 to 12.0 Pa · sec is injected by the penetration of the above-described cosmetic pack liquid in a uniform state, a sheet like a conventional face mask packaging body is used. Since no space is formed on the left and right sides of the substrate, the substrate sheet 1 can be uniformly impregnated.
Actually, the face mask rod-shaped body formed by the above method is put in a stick-shaped packaging bag, and a cosmetic liquid adjusted to a predetermined viscosity using a thickener is injected and filled, and then the upper part of the opening of the packaging bag is covered. A package was manufactured by sealing and sealing, and a cosmetic liquid impregnation test was conducted.

The cosmetic liquid used in the impregnation test has the same composition as the examples and comparative examples except for the thickener, as shown in Table 1.

Three types of thickeners shown in Table 2 were used, and the viscosity of the cosmetic liquid was adjusted to 3.5 Pa · sec, 7.0 Pa · sec, and 12.0 Pa · sec. In order to adjust the viscosity of the pack cosmetic liquid within the above range, a known water-soluble polymer compounded in the cosmetics field can be used as a thickener. Among them, carboxyvinyl polymer, ammonium polyacrylate, etc. A polyacrylic acid polymer is particularly preferable because it can be used at 12 Pa · sec.
In addition, No. The second associative thickener used was “ADEKA NOL GT700” manufactured by Adeka, and the ammonium polyacrylate-based thickener used “SIMULGEL A” manufactured by Seiwa Kasei.

After injecting and filling the cosmetic liquid, the package body in which the upper part of the opening of the packaging bag was hermetically sealed was allowed to stand at room temperature for one week (in this series of steps, no pressure was applied to the packaging bag except for the upper seal part). ). No. No. 1 with a viscosity of 3.5 Pa · sec. No. 2 with a viscosity of 7.0 Pa · sec. In Example 3, the viscosity was 12.0 Pa · sec, and after standing for 1 week, the packaging bag was opened, the face mask 1 ′ was taken out, and the face mask 1 ′ was taken out and pulled to both sides.
FIG. 3A to FIG. 3C are views showing a state in which the face mask 1 ′ developed in Examples 1 to 3 is impregnated with the cosmetic liquid. The impregnation states of the cosmetic liquid viscosity of 3.5, 7.0, and 12.0 Pa · sec indicate that the cosmetic liquid is uniformly impregnated on the entire face mask 1 ′.

  For comparison, a face mask having the same shape was Z-folded in the horizontal direction and then folded in the vertical direction to form a folded body. Put this face mask folded body in a flat bag where the width of the container is wider than the width of the folded body so that spaces are formed on both the left and right sides without winding, and after pouring and filling the same cosmetic liquid as above, In order to facilitate the impregnation of the cosmetic liquid, pressure was applied to the bag surface, and the upper opening was hermetically sealed to produce a package. This package was allowed to stand at room temperature for 1 week. Then, the packaging bag was opened, the face mask was taken out, and it was developed by holding the knob and pulling it to both sides.

No. No. 1 having a viscosity of 3.5 Pa · sec. No. 2 with a viscosity of 7.0 Pa · sec. 3 having a viscosity of 12.0 Pa · sec as Comparative Example 3, after standing for 1 week, the packaging bag was opened, and the face mask 1 ′ was taken out and developed.
FIGS. 4A to 4C are diagrams showing the cosmetic liquid impregnated state of the developed face masks of Comparative Examples 1 to 3. FIGS. The impregnation states of the cosmetic liquid viscosity of 3.5, 7.0, and 12.0 Pa · sec indicate that the face mask has a portion that is not impregnated with the cosmetic liquid.

  In the face mask cosmetic liquid impregnated state of the developed face masks of Comparative Examples 1 to 3, the face mask is not impregnated with the cosmetic liquid. By packing the rod-shaped body 13 formed by winding up from the lower part of the base material sheet folded in the direction with the packaging bag 20, it is for packs in a uniform state in all directions from the center of the rod-shaped body 13 to the outside. Since the cosmetic liquid penetrates, even if a high-viscosity cosmetic liquid for packs having a viscosity of 3.5 to 12.0 Pa · sec is injected, there is a space on both the left and right sides of the sheet base material as in the case of a conventional face mask package. It was found that the base sheet 1 can be uniformly impregnated without being formed.

Next, with reference to FIG. 2, the process of developing the face mask 1 'folded and wound will be described.
Since the knob 2 protrudes outward from the face-shaped side edge of the base sheet 1, when the cut 16 is opened, the upper portion of the cut 16 is removed from the opening from the rod 13. The tip 2 'of the knob 2 with the protruding cut 3 appears. The tip 2 'of the knob 2 is grasped with the left thumb and index finger and picked up from the packaging bag 14, and pulled up until the knob 2 at the bottom of the bar 13 appears. Then, when the grip 2 at the bottom of the pulled up rod 13 is grasped with the right thumb and forefinger and the grasped finger is slowly spread in the opposite directions, the face mask 1 'is Z-folded in the lateral direction. Therefore, the tension tension pulling left and right is larger than the adhesive force between the face masks 1 'in the folded and wound state, so that the Z-fold face mask 1' is developed in the lateral direction. Simultaneously with the expansion, gravity acting on the rolled up face mask 1 'is applied to the tensile tension, so that the rolled up face mask 1' easily expands downward and continues to expand in the left-right direction. A single face mask 1 'as shown in FIG. 2a is easily deployed. The operation is completed by attaching it to the face while sticking it.

  As can be understood from the description of the developing process of the face mask 1 ', the picked portion 2 having the cut 3 of the extracted face mask 1' is gripped with the left hand and the other picked portion 2 is gripped with the right hand and pulled in the left-right direction. However, as described above, the knob part 2 is outward from the side edge of the face shape of the base sheet 1, so that when the packaging bag 14 is opened, the knob part 2 can be easily grasped with a finger, The knob 2 is provided at both ends of the face-shaped head, and the face mask 1 'is folded in the Z-direction in the lateral direction. Even if the tension is high due to the use of a high-viscosity cosmetic, the tension is much greater than that, so that the operation of spreading the face mask 1 'in the lateral direction can be easily performed. At the same time as the deployment, the gravity of the rolled up face mask 1 'is applied to the tensile tension, so that the rolled up face mask 1' easily expands downward and continues to expand in the left-right direction. The operation until the face mask 1 'is unfolded can be easily performed by simply grasping and pulling the knob 2 with the left and right fingers, and the time for unfolding the face mask 1' can be reduced.

  In addition, although it demonstrated that the notch 3 was provided in the front-end | tip of the right knob | pick part 2, you may provide in the front-end | tip of the left knob | pick part 2 naturally, and is not limited to the notch | incision 3. Any mark may be used as long as it is a mark indicating the left side, for example, a mark having a small hole shape or a color mark. In addition, although the folding method in the vertical direction has been described by valley folding, mountain folding may be used, and if the vertical length is shortened, Z folding may be performed. Moreover, although the knob | pick part 2 of the said embodiment showed the example of the square shape of a tip semicircle as an example of the shape, the shape of the knob | pick part of this invention is not limited to this shape, Face-shaped Various shapes such as a rectangular shape, a square shape, a semi-elliptical shape, and the like can be used as long as the shape protrudes outward from the side edge of the cheek at both ends of the head. The length of the semicircular square shape at the tip is preferably a length that reaches the position of the corner of the eye, but the knob 2 is located at both ends of the face-shaped head of the sheet base material 1 at the side edges of the cheek. It does not have to be a length that reaches the position of the corner of the eye as long as it protrudes outward.
