For example, after opening the opening 30 and taking out only one mask from the plurality of masks 100, the opening 30 is resealed so that the remaining masks 100 can be kept in a good sanitary condition.

A plurality of patterns 15 are provided on the surfaces (outside surfaces) of the front side portion S1 and the rear side portion S2 of the housing member 10 . The pattern 15 is provided to allow the user to visually recognize various types of information regarding the container 1 (mask 100). For example, the name (e.g., brand name and sub-brand name) and characteristics (e.g., material and shape of the mask 100, filtration performance) of the mask 100 housed inside, graphics that make the mask 100 image (e.g., mask picture) ), the number of stored items, etc. are provided as a pattern 15 . In addition, as the pattern 15, display of various authentication marks (not shown) may be provided. The pattern 15 is mainly formed by printing.
FIG. 3 is a diagram for explaining the cross-sectional structure of the base sheet 11 that constitutes the housing member 10. As shown in FIG. The base sheet 11 is a laminated sheet member formed by laminating a plurality of sheet members in the thickness direction. The base sheet 11 of the present embodiment includes an outer layer 11a arranged on the outer side in the thickness direction (the front surface side of the housing member 10) and an inner layer 11b arranged on the inner side in the thickness direction (the rear surface side of the housing member 10). It has a two-layer structure with However, the base sheet 11 may have three or more layers.

At least a portion of the outer layer 11a is made of paper. Here, "paper" is manufactured by agglutinating plant fibers, etc. In a broad sense, in addition to synthetic paper manufactured using synthetic high-molecular substances as raw materials, paper containing fibrous inorganic materials is also included. shall include Since the outer layer 11a is made of a paper material, it is easy for the user to recognize that the container 1 is a so-called "plastic-free" product in which petroleum-derived materials are reduced, and the user can be given an environment-friendly image. The outer layer 11a in this embodiment is desirably made of "paper" made of plant fibers such as pulp fibers, and more desirably, the entire outer layer 11a is made of recycled paper.

At least a portion of the inner layer 11b is made of resin. Here, the "resin" is a synthetic resin made of a polymer compound, and thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, and polyethylene terephthalate (PET) can be used. By providing a layer of resin inside the outer layer 11a made of paper, moisture contained in the atmosphere (including water droplets in the shower room, etc.) is suppressed from entering the container 1 from the outside to the inside. It is possible to easily maintain the moisture resistance of the mask 100 housed inside.

In addition, the pattern 15 described above is provided on part of the surface of the base sheet 11 (that is, the outer surface in the thickness direction of the outer layer 11a). A coating layer 16 that covers the outer layer 11a of the base sheet 11 is provided on the outermost side of the base sheet 11 in the thickness direction. In this specification, such a coating layer 16 is also described as being part of the base sheet 11 .

The coating layer 16 is a layer formed by applying a predetermined liquid over the entire surface of the base sheet 11 . Examples of liquids to be applied include water-soluble inks in which additives are added to water-soluble acrylates. In addition, it is desirable that the coating layer 16 has a non-uniform thickness and has fine irregularities formed on its surface. By forming such a coating layer 16, it is possible to adjust the glossiness of the surface of the base sheet 11 to give a so-called matte tone. That is, the covering layer 16 can be a matte coating layer. Although FIG. 3 shows an example in which the coating layer 16 is formed on the surface side of the pattern 15 in the thickness direction, the pattern 15 and the coating layer 16 may be formed at the same timing. The design 15 may be formed after the coating layer 16 is formed.

(Sanitary article 100)
Next, the sanitary article 100 (mask 100) housed in the housing member 10 will be described. FIG. 4A is a front view of mask 100 in an unfolded state. FIG. 4B is a diagram showing a folded state of the mask 100 when accommodated in the accommodation member 10. FIG. 4A and 4B, the mask 100 has a mask vertical direction, a mask horizontal direction, and a thickness direction that intersect each other. In addition, the side facing the wearer's skin in the wearing state is defined as the skin side in the thickness direction (skin side), and the opposite side is defined as the non-skin side in the thickness direction (non-skin side).

The mask 100 is a so-called disposable mask, and has a mask main body 110 that can cover at least the wearer's mouth and nostrils, and ear hooks 120 that are hung on the wearer's ears. The mask body portion 110 includes a pair of

sheet portions

The

sheet portions

113 and 114 of the mask main body portion 110 are provided with members having a filter function that is highly effective in capturing fine particles such as virus droplets, bacterial droplets, and pollen. An example of a member having a filter function is a sheet obtained by dielectrically polarizing (electretizing) a nonwoven fabric made of polyolefin fibers. By the electret treatment, a predetermined amount of positive or negative charge is applied to the surface of the polyolefin fiber to form a polarized dielectric state, thereby obtaining a collection function.

The ear hooking part 120 is a stretchable sheet formed with an opening 121 for hooking the ear, and for example, a stretchable nonwoven fabric is used. The ear hook portion 50 is joined to the skin side surface of the mask main body portion 110 by a joint portion 117, as shown in FIG. 4A.

When folding the mask 100, the mask main body 110 is folded at the central portion (near the joint 115) in the left-right direction so that the skin sides of the

sheet portions

113 and 114 of the mask main body 110 face each other. The

portions

113 and 114 are overlapped in the thickness direction. Then, the ear hooking portion 120 is folded near the boundary portion 130 between the mask body portion 110 and the ear hooking portion 120 so that the mask body portion 110 and the ear hooking portion 120 overlap in the thickness direction. By doing so, the mask 100 is folded as shown in FIG. 4B.

The mask 100 in the folded state is accommodated in the accommodating member 10 in a state in which the upper side in the vertical direction of the mask is aligned with the upper side in the vertical direction of the accommodating member 10 (see FIG. 2). . When storing a plurality of masks 100 in the storage member 10, the masks 100 may be folded as shown in FIG. 4B and then stacked in the thickness direction. A plurality of 100 may be stacked in the thickness direction and then folded. Moreover, the configuration and shape of the mask 100 are not limited to the example shown in FIG.

<Effect of housing member 10>
Next, the effects of the housing member 10 of this embodiment will be described. First, a method for forming the bag-like housing member 10 using the base sheet 11 will be briefly described. 5A to 5C are diagrams explaining a method of forming the housing member 10. FIG. 5A is a plan view of the storage member 10 in the unfolded state when viewed from the inside in the thickness direction (the side where the inner layer 11b of the base sheet 11 is provided), and FIG. 5C is a bag. Fig. 10 is a plan view of the housing member 10 formed in a shape when viewed from the rear side in the front-rear direction;

First, the base sheet 11 is cut into a planar shape as shown in FIG. 5A. As described above, the base sheet 11 includes the front side portion S1 that serves as the front surface of the housing member 10 in the front-rear direction, the rear side portion S2 that serves as the rear surface in the front-rear direction, and the opening 30 that can be opened and closed. It has a folded portion S3 for sealing.

Next, as shown in FIG. 5B, the base sheet 11 is folded in the left-right direction at the first folding position F1 at the boundary between the front side portion S1 and the rear side portion S2, and the inner side surface in the thickness direction of the front side portion S1 and the rear side portion S2 are folded. are overlapped so that the inner surface in the thickness direction of the Then, the opposing surfaces (the inner layers 11b) of the front side portion S1 and the rear side portion S2 are thermally welded to each other at the end portion (referred to as the side end portion 17) opposite to the first bending position F1 in the left-right direction. . Similarly, the facing surfaces (inner layers 11b) of the front side portion S1 and the rear side portion S2 are thermally welded to each other at the lower end portion (referred to as the bottom portion 18) in the vertical direction.

Since the inner layer 11b of the base sheet 11 is made of a thermoplastic resin, when forming the housing member 10, the inner surfaces are thermally welded (heat sealed) to each other, so that the surfaces facing each other in the thickness direction are firmly attached to each other. can be bonded to achieve high moisture resistance. In the housing member 10 of the present embodiment, the base sheet 11 is folded at one (right) end (first folding position F1) in the left-right direction, and the other (left) end in the left-right direction ( The inner layers 11b of the base sheet 11 are thermally welded together at the side end portion 17) and the vertical lower end portion (bottom portion 18). Therefore, since the inside of the housing member 10 is firmly shielded from the outside air except for the unsealing opening 30 provided at the upper end in the vertical direction, high moisture resistance is ensured, and the sanitary condition of the stored items is maintained. can be made easier.

Then, an engaging portion 60 extending in the left-right direction is formed by applying an adhesive to the upper end portion of the folded portion S3 (sealing portion 50). Further, a pressing process is performed on the boundary line between the folding base portion 40 and the sealing portion 50 to form a folding guide line FL along the left-right direction. Note that the engaging portion 60 and the folding guide line FL may be formed at the stage of FIG. 5A.

Next, as shown in FIG. 5C , the base sheet 11 is vertically folded with the boundary between the folded portion S3 and the front side portion S1 as the second folding position F2, and the inner side surface (folded base portion 40) of the folded portion S3 in the thickness direction is folded. They are overlapped so that the inner surface (front base portion 45) in the thickness direction of the front side portion S1 faces each other. Then, the opposing surfaces (the inner layers 11b) of the folded base portion 40 and the front side base portion 45 are thermally welded to each other at the upper end portion (referred to as the upper end portion 19) in the vertical direction. Then, the engaging portion 60 provided in the sealing portion 50 of the folded portion S3 is engaged with the engaged portion 70 of the rear side portion S2. As a result, the opening 30 is sealed by the folded portion S3 (sealing portion 50).

In the housing member 10 of the present embodiment, the coating layer 16 is provided on the outside in the thickness direction of the engaged portion 70, which is the portion with which the engaging portion 60 of the sealing portion 50 is engaged, in the rear side portion S2. is provided (see FIG. 3). Therefore, even if the engaging portion 60 of the sealing portion 50 is peeled off from the engaged portion 70 when opening the opening 30, the surface of the housing member 10 (the outer layer 11a of the base sheet 11 in FIG. 3) is The tearing or damage of the paper constituting the is suppressed. Therefore, the engaging portion 60 of the sealing portion 50 can repeatedly perform the engaging operation and the peeling operation with respect to the engaged portion 70 of the rear side portion S2.

Since the housing member 10 formed in this manner uses paper for the outer layer 11a of the base material sheet 11, it has higher rigidity than a conventional housing member made of a film or the like, and does not easily lose its shape. . Therefore, the shape of the opening 30 is likely to be stable, and the mask 100 stored inside can be easily taken out. In addition, since the sealing portion 50 that seals the opening 30 is not easily broken or damaged, it is possible to securely reseal the opening 30 even after it has been opened once. At that time, even if the engaging portion 60 is peeled off from the engaged portion 70, the coating layer 16 prevents the paper on the surface from being broken, and the adhesive strength of the engaging portion 60 is increased. Since it is difficult to lower, the operation of opening and resealing the opening 30 can be repeated. For example, when taking out only one mask 100 to be used from the container 1 containing a plurality of masks 100, the opening 30 is resealed to keep the remaining masks 100 in a good sanitary condition. be able to.

In order to smoothly open and close the opening 30 repeatedly in the housing member 10 of the present embodiment, the repeated peel strength between the engaging portion 60 and the engaged portion 70 is set to 0.5 N or more and 5.0 N or less. It is desirable to Here, the repeated peeling strength is when the engaging portion 60 is peeled off from the engaged portion 70 and re-engaged with the engaged portion 70 multiple times (n times). Second, it is the magnitude (N) of the force required to peel off the engaging portion 60 from the engaged portion 70 after n times.

For example, when five (n) masks 100 are stored in the storage member 10, the operation of opening and closing the opening 30 must be performed five times to take out the masks 100 one by one. n times). In this case, even after the engaging portion 60 is peeled off from the engaged portion 70 and re-engaged five times (n times), the engaging portion 60 does not stick to the engaged portion 70 . Engageable is required.

If the repeated peel strength is less than 0.5N, the adhesive strength of the engaging portion 60 is reduced and the adhesive strength of the engaging portion 60 is reduced before the engaging/peeling operation of the engaging portion 60 with respect to the engaged portion 70 is repeated five times. It becomes impossible to engage with On the other hand, if the repeated peel strength is greater than 5.0 N, a large force is required to peel off the engaging portion 60 from the engaged portion 70, and the coating layer 16 may be peeled off or the base sheet of the housing member may be peeled off. 11 may break. On the other hand, if the repeated peel strength is 0.5 N or more and 5.0 N or less, even if the opening and closing operation of the opening 30 is repeated five times, the engaging portion 60 maintains a sufficient engaging force. , can be peeled off from the engaged portion 70 with an appropriate force.

The repeated peel strength can be measured using a commercially available tensile tester (for example, Instron: universal material testing machine 5543) as follows. First, the engaging portion 60 and the engaged portion 70 are cut out from the housing member 10 with a predetermined width (for example, 25 mm) to obtain a test piece. Next, of the engaging portion 60 and the engaged portion 70 in the engaged state, the end portion of the engaging portion 60 is held between the chucks on one side, and the end portion of the engaged portion 70 is held between the chucks on the other side. Sandwich Then, a tensile tester is performed with a chuck distance of 10 mm to 20 mm and a tensile speed of 100 mm/min to measure the first peel strength. After the first measurement is completed, the test piece is removed from the tensile tester, placed on a flat surface and engaged again, and the roller is reciprocated once while applying a load of 800 g to the engaged test piece. A second tensile test is performed on the test piece in this state in the same manner as the first time. The peel strength when this operation is repeated n times (for example, 5 times) is defined as the repeated peel strength.

In addition, at the folding portion S3 of the housing member 10, the opening 30 can be opened by folding the sealing portion 50 covering the opening 30 from the rear side along the boundary line with the folding base portion 40. can. That is, the sealing portion 50 is configured to be foldable with respect to the folded-back base portion 40 and functions like a lid having a so-called flap structure, making it possible to facilitate opening and closing operations of the opening 30 . Therefore, after opening the opening 30 and taking out the mask 100, the user can easily seal the opening 30 again.

A folding guide line FL is provided on the boundary line between the folded base portion 40 and the sealing portion 50 . With the folding guide line FL as a reference, the sealing portion 50 can be freely folded with respect to the folding base portion 40 , thereby making it easier to open and close the opening 30 . In particular, the fold-back portion S3 (accommodating member 10) of the present embodiment includes paper, and is more rigid than a film or the like, making it difficult to fold. If the FL is not provided, it may be difficult to open the opening 30 . In contrast, in the present embodiment, the sealing portion 50 can be easily folded along the folding guide line FL, so that the user can stably perform the opening/closing operation.

Further, in the housing member 10 of the present embodiment, a front side folding guide line FL' is provided at a position corresponding to the folding guide line FL in the front side portion S1 facing the folded portion S3 in the front-rear direction (thickness direction). Specifically, a front side folding guide line FL' is provided at the lower end position of the front side base portion 45 in the front side portion S1 and compressed along the left-right direction. The front folding guide line FL' is a reference line for facilitating folding of the front side portion S1, and is formed in the same manner as the folding guide line FL.

6A to 6C are diagrams for explaining the operation when removing the mask 100 from the housing member 10. FIG. 6A to 6C show schematic cross-sections of the accommodating member 10 in which the mask 100 is accommodated, as seen from the left-right direction. 6A, the engaging portion 60 provided in the sealing portion 50 (folded portion S3) is engaged with the engaged portion 70 of the rear side portion S2, thereby sealing the opening 30 in the housing member 10. In FIG. It is in a stopped state. From this state, as shown in FIG. 6B , the engaging portion 60 is peeled off from the engaged portion 70 and the sealing portion 50 is folded along the folding guide line FL, whereby the opening 30 is opened and the housing member 10 is opened. The mask 100 stored inside can be taken out from the opening 30. - 特許庁

However, in the state of FIG. 6B, the folding base 40 and the front folding base 45 are positioned above the opening 30 . Therefore, when the mask 100 is pulled upward from the opening 30, the folding base 40 and the front folding base 45 tend to interfere with each other, and the mask 100 may be difficult to remove. In such a case, as shown in FIG. 6C, the front folding base portion 45 is folded forward with reference to the front folding guide line FL'. Then, since the folding base 40 and the front side folding base 45 move forward from above the opening 30, the space above the opening 30 is opened, and the operation of pulling out the mask 100 upward can be facilitated. Therefore, it becomes easier for the user to take out the mask 100 from the housing member 10 .

In addition, in the housing member 10, the joining strength between the facing surfaces of the folded base portion 40 (rear side portion S2) and the front side folded base portion 45 (front side portion S1) is the same as that of the engaging portion 60 (folded portion S3). It is preferably higher than the engagement strength with the portion 70 (rear side portion S2). That is, in FIG. 5C , it is desirable that the joint strength at the upper end portion 19 is higher than the engagement strength between the engaging portion 60 and the engaged portion 70 . If the joint strength of the upper end portion 19 is weaker than the engagement strength between the engaging portion 60 and the engaged portion 70, the opening and sealing operations of the opening 30 are repeated, and the folding base portion 40 and the front side are bent. There is a risk that the connection with the folded-back base 45 will come off, making it impossible to reseal the opening 30 .

On the other hand, in this embodiment, the engagement between the engaging portion 60 and the engaged portion 70 is performed by attaching an adhesive surface using an adhesive to the coating layer 16 . On the other hand, the joining of the folded base portion 40 and the front folded base portion 45 is performed by heat-sealing the inner layers 11b (thermoplastic resin) of the facing base sheet 11 to each other. Therefore, the joint strength between the folded base portion 40 (rear side portion S2) and the front side folded base portion 45 (front side portion S1) is higher than the engagement strength between the engaging portion 60 and the engaged portion . As a result, even if the operation of opening and sealing the opening 30 is repeated, the peeling of the joint between the folded base portion 40 and the front folded base portion 45 is suppressed, and the opening and closing operation of the sealing portion 50 is stably performed. be able to.

In addition, as shown in FIG. 5C, the length L50 of the sealing portion 50 in the vertical direction of the folded portion S3 is longer than the length L40 of the folded base portion 40 in the vertical direction. As described above, when opening the opening 30, the operation of folding the sealing portion 50 with reference to the folding guide line FL is performed. At this time, if the length L50 of the sealing portion 50 in the vertical direction is short, the distance between the fulcrum (folding guide line FL) and the force point (lower end of the sealing portion 50) becomes short, and the lower end portion of the sealing portion 50 is reduced. A larger force is required when grasping and bending upward, making it difficult to perform the opening operation. In addition, if the length L50 in the vertical direction is short, the area of the sealing portion 50 covering the opening 30 is correspondingly reduced, so the opening 30 itself needs to be made smaller, and the mask 100 may be difficult to remove. be. Therefore, by making the length L50 of the sealing portion 50 longer than at least the length L40 of the folding base portion 40, it becomes possible to facilitate the operation of folding the sealing portion 50 to open the opening 30. Also, the mask 100 can be easily taken out from the opening 30 .

Also, in the housing member 10, the ratio of the weight of the paper portion to the total weight is preferably 50% or more. In the case of FIG. 3, the base sheet 11 has a laminated structure of an outer layer 11a made of paper and an inner layer 11b made of resin. 50% or more. Depending on the country, products with a weight percentage of paper of 50% or more can be labeled as paper products or can be disposed of as paper waste, so the weight percentage of paper is 50%. The above is likely to serve as an indicator that the product is a paper package product. Therefore, by setting the weight ratio of the paper to 50% or more, it is possible to make it easier for the user to recognize that the container 1 of the present embodiment is an environmentally friendly product. In addition, since the inner layer 11b of the housing member 10 is made of a liquid-impermeable resin such as polyethylene, the mask 100 housed inside is less likely to get wet or soiled, even though it is a paper product, thereby ensuring good hygiene. It can make it easier to maintain.

Furthermore, it is more preferable that the paper forming the outer layer 11a of the base sheet 11 is 100% recycled paper. By using recycled paper, the texture and texture of the paper can be easily produced in the housing member 10, and the user can easily recognize that the product is an environmentally friendly product. In addition, since the recycled paper tends to increase the rigidity as compared with ordinary paper, the shape of the bag-shaped containing member 10 is easily stabilized, and the shape of the containing member 10 does not easily collapse even when the opening 30 is repeatedly opened and closed. can be done.

In addition, a coating layer 16 (matte coating) made of water-soluble ink or the like is provided on the outer side (front side) in the thickness direction of the outer layer 11a made of paper. By providing such a coating layer 16, even if the outer layer 11a is made of paper, the outer layer 11a is less likely to be damaged even if the engaging portion 60 is repeatedly engaged and peeled off. can do. In addition, the coating layer 16 makes it possible to increase the water resistance of the outer layer 11a, so that even if water droplets or the like adhere from the outside of the housing member 10, the water will not reach the mask 100 housed inside. can be suppressed. That is, the moisture resistance of the container 1 can be improved.

In addition, it is desirable that the surface roughness of the outermost (front side) surface in the thickness direction of the housing member 10 is rougher than the surface roughness of the innermost (back side) surface in the thickness direction. In this embodiment, a coating layer 16 (mat coating) made of water-soluble ink is provided on the outermost side of the base sheet 11 constituting the housing member 10, and the innermost side of the base sheet 11 is made of resin. An inner layer 11b is provided (see FIG. 3). The surface of the coating layer 16 is formed with fine irregularities, whereas the inner layer 11b is formed relatively smooth. there is With such a configuration, when the mask 100 stored inside is taken out by gripping the storage member 10 with a hand, the outside of the storage member 10 is difficult to slip even if the hand is gripped, and the mask 100 is not slippery on the inside of the storage member 10. becomes difficult to catch. Therefore, the inner layer 11b can make it easier to remove the mask 100 than the cover layer 16, as compared with the case where the surface roughness is rougher.

A comparison of the surface roughness of the outer surface and the inner surface of the base sheet 11 can be performed, for example, as follows. First, a plurality of test pieces each having a size of about 10 cm×10 cm are cut out from the housing member 10 (base material sheet 11). Then, using a commercially available surface tester (for example, Kato Tech Co., Ltd.: KES-FB4), a load of 10 gf is applied to the surface of the test piece (surface on the side to be measured), and 0.5 mm A contact terminal with a width of 0.5 cm wound with a piano wire of a diameter is crimped to the sample. Then, the test piece is horizontally moved by 2 cm at a constant speed of 0.1 cm/sec, and MMD (variation value of average friction coefficient) and SMD (variation value of average friction coefficient) are obtained. Since the smaller the MMD value and the SMD value, the smaller the surface unevenness, it is possible to compare the magnitude of the surface roughness by comparing the MMD value or SMD value measured for each test piece. .

The housing member 10 is composed of a base sheet 11 in which a paper layer (outer layer 11a) and a thermoplastic resin layer (inner layer 11b) are laminated. Then, the resin layer (inner layer 11b) is bent so as to face inward at the end (first bending position F1) of one side (right side) in the left-right direction of the base sheet 11, and the other side (left side) in the left-right direction is folded. ) are thermally welded to each other at the ends (side ends 17). Similarly, the opposing resin layers are thermally welded together at the lower end (bottom portion 18) in the vertical direction (see FIG. 5C). Therefore, gaps are less likely to occur in both the left and right ends and the lower end in the vertical direction of the bag-shaped housing member 10, and the inside of the housing member 10 is easily shielded from the outside (atmosphere). As a result, the moisture resistance of the housing member 10 is improved, and the sanitary condition of the mask 100 housed inside can be easily maintained.

Further, in the container 1 of the present embodiment, the mask 100 is accommodated in the accommodation member 10 after adjusting the accommodation direction. 7A and 7B are diagrams for explaining a cross-sectional state of the state in which the mask 100 is housed in the housing member 10 when viewed from below in the vertical direction. In FIGS. 7A and 7B, the mask 100 is stored inside the storage member 10 in a folded state (see FIG. 4B) in a plurality of layers stacked in the thickness direction.

Among them, in FIG. 7A, the boundary portion 130 where the mask main body portion 110 and the ear hook portion 120 of the mask 100 are folded is positioned on the side end portion 17 side (left side in FIG. 7A) of the housing member 10 in the left-right direction. , in which the mask 100 is housed. When the mask 100 is folded, the mask main body portion 110 and the ear hook portion 120 overlap in the thickness direction at the boundary portion 130, so that the side where the boundary portion 130 is located in the lateral direction of the mask (see FIG. 7A). Left side) tends to be thicker than the other side (right side in FIG. 7A).

In addition, in the housing member 10, the base sheet 11 is folded at the first folding position F1 at the right end in the left-right direction, whereas the base sheet 11 is folded at the left end (side end portion 17) in the left-right direction. The facing surfaces of the material sheet 11 are joined (thermally welded) to each other. Therefore, in the housing member 10 of the present embodiment, the front-rear direction interval between the front side portion S1 and the rear side portion S2 facing each other on the side end portion 17 side (left side) in the left-right direction is It is narrower than the space in the front-rear direction between the front side portion S1 and the rear side portion S2 facing each other on the opposite side (right side) to the side of 17 .

Therefore, as shown in FIG. 7A, by locating the boundary portion 130 of the thick mask 100 on the side of the side end portion 17 where the interval in the front-rear direction (thickness direction) is narrow, the thickness of the thick mask 100 is reduced. Since the boundary portion 130 is sandwiched between the front side portion S1 and the rear side portion S2 of the housing member 10, positional deviation is less likely to occur. This prevents the plurality of masks 100 from moving inside the housing member 10 . In addition, when trying to take out only one mask 100 to be used from among the plurality of masks 100, it is possible to easily prevent the other masks 100 from being pulled out together.

On the other hand, in FIG. 7B, the mask 100 is arranged so that the boundary portion 130 of the mask 100 is located on the side of the first bending position F1 (left side in FIG. 7B) in the left-right direction of the housing member 10, contrary to the case of FIG. 7A. is accommodated. That is, the mask 100 is housed so that the thick boundary portion 130 of the mask 100 is located on the side of the first folding position F1 where the interval in the front-rear direction (thickness direction) is large. In this case, on the side end portion 17 side (right side in FIG. 7B) of the housing member 10, the thickness direction of the mask 100 and the front side portion S1 and the rear side portion S2 of the housing member 10 is larger than in the case of FIG. 7A. Gaps tend to form between them. Therefore, in the vicinity of the side end portion 17 side of the housing member 10, it becomes difficult for the mask 100 to exert a force to expand the front side portion S1 and the rear side portion S2 in the thickness direction. The joint portion (heat-welded portion) between S1 and rear side portion S2 becomes difficult to peel off. This makes it easier to maintain the bag-like shape of the housing member 10 .

FIG. 8 is a diagram illustrating a state in which the mask 100 is housed in the housing member 10 as seen from the rear side in the front-rear direction. When the mask 100 is folded, as shown in FIG. 4B, the area of the portion where the mask main body 110 and the ear hook 120 overlap in the thickness direction is larger than the bottom. That is, in the mask 100 in the folded state, the upper side in the vertical direction of the mask is thicker than the lower side. When such a mask 100 is stored in the storage member 10 , it is stored such that the thick upper region of the mask in the vertical direction is located near the opening 30 of the storage member 10 .

In the folded mask 100 , the thicker the portion, the easier it is to contact the front side portion S<b>1 and the rear side portion S<b>2 when stored in the storage member 10 . If the mask 100 is accommodated so that the upper portion of the mask in the vertical direction is far from the opening 30, the ear hooking portion 120 of the mask 100 is positioned at the front side portion S1 or the rear side in the operation of taking out the mask 100. There is a high probability that the mask 100 will be caught in the portion S2, and the folded shape of the mask 100 may be lost. On the other hand, as shown in FIG. 8, in the up-down direction of the housing member 10, since the upper part of the mask 100 with a large thickness is positioned near the opening 30, the mask 100 can be attached to the ear. The portion 120 is less likely to get caught on the front side portion S1 or the rear side portion S2, and the operation of removing the mask 100 from the housing member 10 without breaking the folded shape of the mask 100 is facilitated.
The upper part of the mask in the vertical direction means the part above the center position in the vertical direction of the mask, and the lower part in the vertical direction of the mask means the part below the center position in the vertical direction of the mask. means

In addition, the opening 30 provided in the housing member 10 has a vertical position lower at the center in the horizontal direction than at both ends in the horizontal direction. That is, as shown in FIG. 2, the opening 30 has a notch shape in which the central portion in the left-right direction is recessed downward. Since the opening 30 has such a notch shape, the opening can be easily widened when the container 1 is opened. For example, since the opening 30 has a notch shape, fingers are likely to be caught in the notch portion, and the operation of opening the opening 30 back and forth is facilitated. In addition, the portions on both sides in the left-right direction function like supports, making it easier to keep the opening 30 open. In particular, the container member 10 of the present embodiment has a paper layer (outer layer 11a), and since it has high rigidity and is difficult to deform compared to a container member made of film, etc., the opening 30 has a notch shape. Thus, the mask 100 can be taken out smoothly.

Also, the bending resistance of the surface of the housing member 10 is desirably 60 mm or more as measured according to JIS L 1096:2010 8.21.1 A method (45° cantilever method). A conventional film containing member has a bending resistance of about 25 mm, and in this case, it is difficult to keep the shape of the containing member constant. On the other hand, if the bending resistance is 60 mm or more, the shape of the housing member 10 can be easily maintained in a rectangular shape as shown in FIGS. The removal operation of the mask 100 can be facilitated.

For measuring the bending resistance, a test piece (for example, a sample of 25 mm × 200 mm) is cut out from the base sheet 11 constituting the housing member, and a cantilever bending resistance tester (for example, CAN-1MCC manufactured by Daiei Kagaku Seiki Seisakusho) is used. It can be measured by the test method based on the above-mentioned JIS method.
