The present invention relates to a mask storage body in which a folded mask is stored in a packaging bag.

Recently, the demand for sanitary masks (hereinafter referred to as "masks") has increased, and in particular, many individually wrapped masks are currently being manufactured and sold because they can always be used in a clean state. However, individually wrapped masks are stored in a packaging bag with the sheet-like mask body open, so the overall size is large and it is difficult to store them in pants or jacket pockets or small handbags. There is a demand for more compact packaged masks. Also, masks housed in transparent packaging bags do not look good.

Patent Document 1 discloses a sanitary mask package in which a sanitary mask folded into a stick shape is individually wrapped in a packaging bag made of resin film, and the mask body is folded in two and then folded into three (DM six-fold). Illustrated. However, when a DM six-folded mask is opened, two folds between the short edges (horizontal direction) and one fold between the long edges (vertical direction) appear as wrinkles (Patent Document 1, Figure 8). In particular, creases between the long edges, that is, vertical wrinkles, are noticeable along the bridge of the nose when wearing a mask, and are not aesthetically pleasing. Furthermore, in a mask equipped with a north wire for bringing the mask into close contact with the wearer's nose, when the mask body is folded in half along the crease between the long edges, the north wire also needs to be bent, which increases the thickness of the mask. Furthermore, when the mask is actually opened and used, there is a risk that the north wire, which has been kept bent for a long period of time during storage, may break at the bending point.

Further, in Patent Document 1, since a transparent packaging bag is used, the contents can be checked, which is preferable, but the folded mask does not necessarily have a beautiful appearance. In other words, when a transparent packaging bag is used, since the mask has an irregular shape, the folded product may not be neatly stored inside the transparent packaging bag due to transportation, stuffing, stacking, compression, load, friction, etc. The initial folded state will collapse, the appearance of the mask inside the packaging bag will become shabby, and there should be no change in the sanitary conditions inside the sealed interior. gives an impression of being unclean. Furthermore, transparent bags cause deterioration and yellowing. In this way, when folded masks are stored in a transparent bag, the user may see the disorganized masks through the transparent bag and feel that the masks are unsanitary and unclean.

Patent Document 2 discloses a folding structure of a mask in which ear straps are attached to both longitudinal ends of a mask main body that is unfolded into a rectangular sheet shape from a folded state, and covers the face including the mouth and nose. A mask folding structure is disclosed in which a plurality of folding lines are provided in the longitudinal direction of the mask body at predetermined intervals in the width direction, and each folding line is alternately folded in opposite directions along the width direction. Ru. Patent Document 2 shows a W-shaped folding structure when viewed from the side, that is, an outward four-fold folding structure.

Patent Document 2 shows that a folded mask is stored in a transparent storage bag, and after storage, the part on the opening side is folded back and closed, and also shows a cutout on the side opposite to the opening to let out air (Patent Document 2) 2 paragraph 0035 and Figure 4). That is, in the folding structure of Patent Document 2, since the opening of the storage bag is not welded, there is no problem of welding together with the ear straps when the storage bag is welded. In other words, in the folding structure of Patent Document 2, the ear straps are not included in the mask body and are placed outside, so if the opening is welded, the ear straps remain near the opening due to friction with the inner surface of the storage bag when the mask is inserted. Although there may be a manufacturing defect in which the ear straps are overlapped and welded to the storage bag, since the opening is not welded in the first place, Patent Document 2 does not disclose or suggest an idea for solving this problem.

In addition, the storage bag shown in Patent Document 2 does not have the opening sealed by welding and has a cutout on the opposite side of the opening, that is, has a structure with ventilation holes at both ends of the storage bag, so air leaks into the storage bag. There is a risk that the stored mask may be contaminated by bacteria, dust, etc. in the air. Furthermore, in Patent Document 2, as in Patent Document 1, a transparent storage bag is used, so if the arrangement and folding structure of the mask inside collapses, the aesthetic appearance may be impaired, and the transparent bag may yellow, deteriorate, etc. , users have the impression that the mask is not hygienic before wearing it.

On the other hand, when folded masks are stored in opaque packaging bags, the condition of the contents cannot be visually checked, so if there are multiple variations of individually wrapped masks, for example, some kind of identification method is required to distinguish the contents. (First issue). In addition, if a defective product is manufactured in which the mask ear straps are welded together with the packaging bag, absolute measures must be taken in advance to prevent the ear straps from being welded, as it is not possible to visually see the inside of the opaque packaging bag. 2). FIG. 12 shows a defective mask container 100 in which the ear straps 106 of a mask 101 housed in an opaque packaging bag 130 are erroneously welded 110 at the end seal 135 at the welding location. In FIG. 12, the mask 101 and the ear straps 106, which are not visible from the outside of the opaque packaging bag 130, are indicated by dotted lines. From the above, when masks are individually housed in opaque packaging bags, the first and second problems described above exist, and it is necessary to solve these problems.

Therefore, an object of the present invention is to provide a compact mask storage body that maintains the cleanliness of the mask and has high aesthetics. Another object of the present invention is to provide a mask container that solves the conventional problems caused by the use of opaque packaging bags.

The mask container of the present invention has a mask container 10, 10' in which a folded body 2 obtained by folding a mask 1 is hermetically stored in a packaging bag 30, 30'. The mask body 11 has at least an outer layer 5b on the opposite side of the inner layer 5a, and an ear strap 6 having string ends 6a, 6b connected to the four corners of the inner layer 5a of the mask body 11. The folded body 2 has a folded structure in which the mask main body 11 encompasses the ear straps 6 and the outer layer 5b forms a pair of outer surfaces 12a, 12b by folding at least twice, and the folded body 2 The packaging bag 30, 30' has an elongated shape with a folded length L2 corresponding to the length in the longitudinal direction of the mask main body 11 and a folded width W2 shortened from the length in the transverse direction of the mask main body 11. The packaging bag 30, 30' is opaque, and the color of the bag outer surface 31 of the packaging bag 30, 30' is the same as that of the packaging bag 30, 30'. It has substantially the same color as the outer layer 5b of the mask 1.

When using conventional transparent packaging bags, the mask does not have a fixed shape, so it moves within the packaging bag during transportation, etc., and over a long period of time, it collapses or the folds shift, and if the packaging bag is placed vertically, the mask may move downwards. Those who fall and see the situation have a bad impression of uncleanness even before opening the packaging bag. In contrast, in the present invention, opaque packaging bags 30, 30' are used, thereby avoiding the disadvantage of giving a bad impression from the appearance of the mask 1 inside the packaging bags 30, 30' before use. In addition, opaque packaging bags 30, 30' allow for clearer printing of barcodes and characters than transparent ones, and higher barcode reading accuracy. In the present invention, which uses opaque packaging bags 30, 30', as an identification means, the outer surface 31 of the packaging bags 30, 30' is made the same color as the outer layer 5b of the mask 1, so that it is possible to misidentify the color of the mask 1, which cannot be seen from the outside. To solve the first problem due to the use of opaque packaging bags 30, 30' by allowing the packaging bags 30, 30' to be opened without opening. Since the ear straps 6 are connected to the inner layer (mouth layer) 5a of the mask body 11 and are surrounded and folded by the mask body 11, when the packaging bags 30, 30' are welded and sealed, there is a risk of defective products being welded together with the ear straps 6. Manufacture can be prevented. That is, the folding structure that prevents the ear straps 6 from coming off from inside the mask body 11 prevents the second problem caused by the use of opaque packaging bags 30, 30'.

In the present invention, the outer layer 5b is folded twice to form the outer surfaces 12a and 12b of the folded body 2, so that the outer layer 5b is exposed to the outside, that is, the folded structure in which the inner layer 5a on the side that contacts the human face is not exposed. is formed. This prevents dust, bacteria, etc. floating in the air from adhering to the inner layer 5a immediately after the packaging bags 30, 30' are opened, and the clean state of the mask 1 is maintained until it is worn. In addition, the folded body 2 and the packaging bags 30, 30' that surround and package it have a sophisticated elongated shape (stick shape), have a smart and highly designed design, and have a beautiful outline silhouette. The mask containers 10, 10' appear to have slim bodies with constrictions. Therefore, the present invention can provide the mask containers 10, 10' that stimulate the consumer's desire to purchase, and can be provided as the smallest sales unit.

In the embodiment of the mask container according to the present invention, the folds forming the folded body 2 include a first fold 8a extending substantially parallel to each other between the pair of short edges 14a, 14b of the mask body 11; Consisting of a second fold 8b and a third fold 8c, when the mask main body 11 is open, the first fold 8a is arranged between the second fold 8b and the third fold 8c, and when folded The body 2 has a folded structure in which the second fold 8b and the third fold 8c are aligned.
The folded body 2 has a folded structure in which the folded body 2 is folded twice by four-folding. It has a folded structure in which one outer layer 5b1 and the other outer layer 5b2 located on both sides of the third fold 8c are in surface contact with each other. In other words, to fold the volume into four, first fold the mask body 11 at the first fold 8a near the center so that the pair of inner layers 5a1, 5a2 are aligned (so that the pair of long edges 13a, 13b are aligned), Next, using the second and third folds 8b and 8c as folds, the pair of outer layers 5b1 and 5b2 are folded in the same direction as the first folding so as to meet each other.
The mask 1 includes one or more pleat lines 21-24 extending between the pair of short edges 14a, 14b of the mask body 11, and the first fold 8a and the second fold 8b have two pleat lines 22. , 24, which are formed substantially collinearly.
The sheet-like nonwoven fabric constituting the outer layer 5b is folded back toward the inner layer 5a at a pair of long edges 13a, 13b of the mask body 11, and the folded pieces 9a, 9b at least connect the ear straps 6 to the mask body. It extends to the ear string welding part 16 connected to 11.
The total length L1 in the longitudinal direction is 180 to 240 mm, and the total width W1 in the short direction is 25 to 40 mm.
A transparent portion 32 is provided at the end of the packaging bag 30'.

The manufacturing method of the mask container includes the steps of arranging the ear straps 6 with the string ends 6a and 6b connected to the inner layer 5a of the mask body 11 on the inner layer 5a of the mask body 11, and placing the ear straps 6 on the inner layer 5a. A process of folding the mask body 11 arranged at least twice to form a folded body 2 that includes the ear straps 6 inside the inner layer 5a, a process of wrapping the folded body 2 in packaging bags 30, 30', and a process of welding. a step of sealing the packaging bags 30, 30' to form a continuous body 40 of the packaging bags 30, 30' in which the folded body 2 is hermetically housed; and cutting substantially perpendicularly at regular intervals to form individual mask containers 10, 10'.

In the above manufacturing method, the folded body 2 is not inserted through the opening, but is wrapped in the packaging bags 30, 30', so the movement of the folded body causes frictional contact between the folded body and the inner surface of the packaging bag. This will not cause the folded body 2 to lose its shape, and the ear straps 6 will not come off from the folded body 2 to the outside. Therefore, manufacturing defects such as welding of the mask body 11 and/or the ear straps 6 and the packaging bags 30, 30' together can be reliably avoided.

The mask container of the present invention has a compact and elongated shape that maintains the cleanliness of the mask with its sealed structure and has a high aesthetic appearance, making it easy to store in a bag or the like and ideal for carrying when going out. In addition, since the outer surface of the packaging bag can be made colorful to match the color of the mask, when the mask container is displayed as a product in a store, it creates a brightly colored appearance that stimulates the consumer's desire to purchase, along with a smart elongated shape. Furthermore, although an opaque packaging bag is used, the possibility of welding of the ear straps can be avoided in advance due to the folding structure that prevents the ear straps from coming off, thereby reducing the proportion of defective products and improving the yield.

Embodiments of the mask container of the present invention will be described with reference to FIGS. 1 to 10. The following embodiments are illustrative and do not limit the technical scope of the present invention.
1 and 2 are a front view showing the front surface and a rear view showing the back surface of the mask container 10 according to the present invention. ) is sealed and stored inside the packaging bag 30. Furthermore, in order to make the folded body 2 more compact or to adjust the shape of the folded body 2, it may be folded three times or more. The packaging bag 30 of the mask container 10 has an elongated shape (stick shape) that seals and surrounds the elongated folded product 2, and when the mask container 10 encloses the folded product 2, it is shown in FIGS. 1 and 2. The slightly concave outline near the center creates a visually beautiful silhouette. The total length L1 in the longitudinal direction of the mask container 10 shown in FIG. 1 is 150 to 260 mm, preferably 180 to 240 mm, and the total width W1 in the short direction is 20 to 50 mm, preferably 25 to 40 mm. The longitudinal length of the enclosed mask 1 varies from a child's size to an adult male's size, and considering the compact size that can be placed in a handbag, etc., it is preferable that the total length L1 = 180 to 240 mm x total width W1 = 25 to 40 mm as described above. .

The packaging bag 30 shown in FIGS. 1 and 2 can be formed from a film sheet made of resin, nonwoven fabric, woven fabric, or paper, and a resin film sheet with high airtightness is particularly preferable. The packaging bag 30 has a structure including a bag body 33 containing the folded body 2, a pair of end seals 35a and 35b that seal the packaging bag 30 at both ends of the bag body 33, and a seal between the pair of end seals 35a and 35b. 33 and a center seal (back sticker) 37 shown in FIG. 2 extending in the longitudinal direction. One end seal 35a of the packaging bag 30 has a V-shaped notch 39 to assist in opening the packaging bag 30. The packaging bag 30 is colored or colorless and opaque, and the color of the outer surface 31 of the packaging bag 30 is substantially the same color as the outer layer 5b of the mask 1 sealed in the packaging bag 30, making it difficult to use as a mask. A person can recognize the color of the mask 1 before opening the packaging bag 30. Further, mask manufacturers can provide masks 1 and mask containers 10 of various colors, and when mask containers 10 of multiple colors are displayed in a store or the like, they are colorful and eye-catching. The packaging bag 30 and the mask 1 can be of any color, such as black, white, brown, gray, red, pink, orange, yellow, green, blue, and purple.

FIG. 3 shows that a person who wants to wear the mask 1 tears the packaging bag 30 from the notch 39 in the direction of the arrow 39a in FIG. Indicates the condition. In this state, the bag outer surface 31 of the packaging bag 30 and the outer surfaces 12a, 12b of the folded body 2 are substantially the same color.

FIG. 4 shows the folded body 2 after being taken out from the packaging bag 30 or before being wrapped in the packaging bag 30. The folded body 2 has a folded length L2 corresponding to the length in the longitudinal direction of the mask body 11 (FIG. 7), and a folded width W2 that is shortened to about one-fourth of the length in the transverse direction of the mask body 11. It has an elongated shape. This reduces the area to about one quarter, making it easy to store in a handbag or pocket. The folding length L2 and the folding width W2 are slightly smaller than the total length L1 and the total width W1 of the mask container 10 (L2<L1, W2<W1).

The folded body 2 in FIG. 4 is formed by rolling and folding into four. "Maki 4-fold" is a method of folding in half (fold in half) and then folding it in half again in the same direction. do. Specifically, the ear straps 6 are located on both sides of the first fold 8a along the first fold 8a of the mask 1 (FIGS. 7 and 11(a)) in which the ear straps 6 are arranged on the inner layer (mouth layer) 5a. One inner layer 5a1 and the other inner layer 5a2 are folded to match (bring surface contact to each other) to form a folded intermediate body 4 (FIGS. 6 and 11(b)), and the second and second inner layers of the folded intermediate body 4 are Along the third folds 8b and 8c, one outer layer 5b1 and the other outer layer 5b2 located on both sides of the third fold 8c are folded together (bringing them into surface contact), and the folded body 2 (Figs. 4 and 11 (c)) is formed. By folding the mask into four rolls, the area can be reduced to about one-fourth the size of the planar shape of the mask body in conventional packaging, making it easy to carry. As shown in FIG. 4, the folded body 2 has a folded structure in which the mask body 11 encompasses the ear straps 6, and the outer layer 5b forms one outer surface 12a. The other outer surface 12b (FIGS. 11(c) and 11(d)) is formed on the back side of one outer surface 12a.

5(a) is a schematic sectional view taken along the line A-A in FIG. 4, and FIG. 5(b) is a schematic sectional view showing the folded body 2 of FIG. 5(a) opened in a ladle shape. In both figures, the folded body 2 is shown with the ear straps 6 omitted for the sake of simplification. FIG. 6 shows a single fold after opening the second and third folds 8b, 8c from the folded body 2 of FIG. 4 or before folding along the second and third folds 8b, 8c. Folding intermediate 4 is shown. As shown in FIG. 6, the ear straps 6 are held between the mask body 11, and it can be expected that the folded body 2 that is folded one more time will also include the ear straps 6.

FIG. 7 shows the mask 1 after further unfolding the first fold 8a from the folding intermediate body 4 of FIG. 6 or before folding along the first fold 8a. As shown in FIG. 7, the ear straps 6 are arranged on the inner layer 5a of the mask body 11, and it can be expected that the ear straps 6 are included even in the folded body 2 folded twice.

8 and 9 show the back and front surfaces of the mask 1 after opening the ear straps 6 or before closing the ear straps 6 from FIG. 7, respectively. The mask 1 includes a mask body 11 made of non-woven fabric or resin, and the mask body 11 has an inner layer 5a (FIG. 8) on the side that contacts the human face and an outer layer 5b (FIG. 9) on the side opposite to the inner layer 5a. Although a two-layered structure may be used, it is preferable to laminate an intermediate layer (not shown) between the inner layer 5a and the outer layer 5b to form a three-layered structure. In this embodiment, a mask body 11 having a recess 29 near the center of a pair of short edges 14a, 14b is illustrated, but a mask body with straight short edges may be used and there is no restriction on the outer shape of the mask body 11. . The ear strings 6 of the mask 1 have their string ends 6a, 6b connected to the ear string welds 16 of the inner layer 5a at the four corners of the mask body 11. Since the ear straps 6 are welded to the inner layer 5a side, when folded, the inner layer 5a encompasses the ear straps 6, thereby avoiding an accident of welding of the ear straps 6 at the end seals 35a, 35b. In other words, if the ear straps are welded to the outer layer and placed inside the inner layer, the ear straps will pass through the outside of the short edge and even after being folded, a portion of the ear straps will remain outside the short edge. There is a risk of welding.

As shown in FIGS. 8 and 9, the mask 1 includes one or more pleat lines 21-24 extending substantially parallel to each other between the pair of short edges 14a, 14b of the mask body 11, and in FIG. Three straight second, third and fourth pleat lines 22-24 are provided on the outer layer 5b, and in FIG. 9, three straight first, second and third pleat lines 21-23 are provided on the outer layer 5b. It will be done. The pleat lines 21-24 are lines folded to form pleats (folds, folded parts) 7 (FIG. 5(b)), and the pleats 7 are lines that allow the mask body 11 to expand and contract in the vertical direction when worn. It also has a folding structure that provides three-dimensionality in the front-back direction. On the other hand, since the mask body 11 is divided into four parts in the four-fold roll shown in this embodiment, the first, second and third folds 8a, 8b, 8c of the three folds forming the folded body 2 are , in the mask 1 after being opened from the folded body 2, it appears between the pair of short edges 14a, 14b of the mask body 11. On the other hand, in the mask 1 before forming the folded body 2, the first, second and third folds 8a, 8b, 8c shown by dotted lines either do not actually appear (imaginary lines, imaginary lines) or are folded. It appears as some kind of landmark line to make it easier.

As shown in FIGS. 8 and 9, the first fold 8a is arranged between the second fold 8b and the third fold 8c. As shown in FIGS. 5A and 6, the folded body 2 has a folded structure in which the second fold 8b and the third fold 8c are aligned and the outer layers 5b1 and 5b2 are in surface contact with each other. Here, alignment means that the second fold 8b and the third fold 8c are parallel to each other on substantially the same line along the longitudinal direction of the mask body 11 in the folded state. The folds consist only of horizontal first, second and third folds 8a, 8b, 8c extending between the pair of short edges 14a, 14b, and extending between the pair of long edges 13a, 13b. There are no vertical folds. Therefore, the formation of vertical wrinkles that deteriorate the appearance when the mask 1 is worn can be avoided, and the present embodiment does not impair the appearance. Moreover, since there is no vertical fold extending between the long edges 13a and 13b, the north wire 15 (FIG. 5) placed between the pair of crimping parts 15a and 15b shown in FIGS. 8 and 9 is folded. There's no need. Therefore, an increase in the thickness of the folded body 2 that would occur when the north wire 15 is folded together with the mask body 11 can be prevented, and the overall compact mask housing 10 can be formed.

As shown in FIGS. 8 and 9, the first fold 8a and the second fold 8b are formed substantially on the same line with respect to the second pleat line 22 and the fourth pleat line 24, respectively. Therefore, two of the three fold lines 8a, 8b are substantially on the same line as the pleat lines 22, 24, so the folds (wrinkles) 8a, 8b are inconspicuous and do not give the impression of a worn-out mask. Does not impair the appearance when wearing a mask.

As shown in FIGS. 5 and 8, in this embodiment, folded pieces 9a, 9b are formed by folding the sheet-like nonwoven fabric constituting the outer layer 5b of the mask body 11 toward the inner layer 5a at a pair of long edges 13a, 13b of the mask body 11. Be prepared. As shown in FIG. 8, the ends of the folded pieces 9a, 9b reach at least the ear strap welding part 16 that connects the ear strap 6 to the mask body 11. As a result, the ear strap welded part 16 is the part where at least three layers, that is, the outer layer 5b, the inner layer 5a, and the folded pieces 9a, 9b are laminated, so that the ear strap 6 can be detached from the mask body 11 by reinforcing the strength of the welded part. prevent. Further, the north wire 15 can be arranged between the folded pieces 9a, 9b and the inner layer 5a.

FIG. 10 shows a second embodiment of the mask container 10' according to the present invention, which includes a transparent part 32 at the end of the packaging bag 30'. The mask accommodating body 10' has substantially the same effects as the mask accommodating body 10 of the first embodiment, and also improves the defect when the outer surface 31 of the opaque packaging bag 30' is dark colored. . That is, when sealing the packaging bag 30', if a defect occurs in the end seals 35a, 35b where the mask body 11 or the ear straps 6 are welded together with the packaging bag 30', the opaque packaging bag 30' When the color of the bag outer surface 31 is dark, for example, black, navy blue, brown, purple, etc., it is difficult to detect defects by light irradiation or visual inspection. For this reason, in this embodiment, a transparent part 32 is provided at the end of the packaging bag 30' as a monitoring window, so that defects in welding the ear straps to the bag (FIG. 12) can be detected reliably by visual inspection, sensors, etc.

Hereinafter, an embodiment of a method for manufacturing the mask containers 10, 10' will be described with reference to FIG. 11.
First, the mask 1 is formed by welding and connecting the string ends 6a, 6b of the ear straps 6 to the four corners of the inner layer 5a of the mask body 11. Next, the ear straps 6 connected to the inner layer 5a of the mask body 11 are placed on the inner layer 5a of the mask body 11. That is, as shown in FIG. 11(a), the ear string 6 is closed on the inner layer 5a. Thereafter, the mask 1 is conveyed to a folding device by a high-speed conveyor belt, and the mask body 11 with the ear straps 6 arranged on the inner layer 5a is folded twice in the same direction by the folding device to form a folded product that includes the ear straps 6. Form 2. Specifically, the first fold 8a of the mask body 11 is pushed from the front side in FIG. 11(a) with, for example, a plate-shaped first folding member, and one inner layer 5a1 and the other inner layer 5a2 are brought into surface contact. A folded intermediate body 4 shown in FIG. 11(b) is formed. Next, the second and third folds 8b and 8c of the folded intermediate body 4 are pushed from the front side in FIG. A folded body 2 shown in FIG. 11(c) is formed.

Next, the folded body 2 is wrapped in a packaging bag 30. Specifically, as shown in FIG. 11(d), the folded body 2 is placed on the film sheet 34, and both edges 34a and 34b of the film sheet 34 are overlapped. Next, the packaging bags 30 are sealed by welding (welding, crimping, heating and pressing) to form a continuous body 40 of the packaging bags 30 in which the folded bodies 2 are sealed. That is, the overlapped edge portions 34a and 34b are heat welded to form a center seal 37, and the film sheet 34 is heat welded at regular intervals in the longitudinal direction to form end seals 35, and the folded body 2 is hermetically housed. Then, a continuous body 40 of the packaging bags 30 shown in FIG. 11(e) is formed. Furthermore, by cutting the end seals 35 of the continuous body 40 of the packaging bag 30 at substantially constant intervals with a cutter substantially perpendicular to the continuous direction, individual end seals 35 having notches 39 in one end seal 35a as shown in FIG. The mask container 10 can be manufactured.
