In the sanitary napkin storage box of this kind, it is general to adopt a structure in which the ring-shaped sewing eye is covered and a resin film having a slit is attached on the inner surface of the paper box.

Therefore, in this type of conventional product, when the resinous film and the paper box are separated after use, the film inside the paper box is peeled off.

On the other hand, a sanitary napkin storage box is also disclosed in which a different sewing eye surrounding the film-attached portion is formed and the film-attached portion is separated from the paper box body by holding it after use (see, for example, Patent Document 1, etc.).

However, even with the construction of the sanitary napkin storage box, it is necessary to further separate the paper portion and the resin film from each other in the separated film-attached portion, so that the complexity of the operation is not reduced.

On the other hand, a sanitary napkin storage box (for example, Patent Document 2) that does not use a film is provided on the market as a sanitary napkin storage box that does not have complicated operations.

However, the structure using the film tends to take out the tissue paper, and the film is superior in terms of moisture-proof property, sealing property and waterproof property.

On the other hand, in the conventional sanitary napkin storage box, if a large amount of tissue paper is required at once, the pop-up operation of dozens of times must be repeated, or the box must be destroyed to take out the bundle of tissue paper accommodated therein.

In the sanitary papermaker's storage box of this kind, it is known that if the use of the sanitary papermill storage box is progressed and the remaining amount of the tissue paper inside is reduced, the distance between the tissue paper bundle and the upper surface of the paper box becomes distant, Taking this into consideration, it is necessary to secure a technique for preventing deterioration of take-out property when the remaining amount of tissue paper is reduced.

Next, embodiments of the present invention will be described in detail below with reference to the drawings.

(First Embodiment)

The first embodiment will be described in detail below with reference to Figs. Fig. 1 is a perspective view of the sanitary napkin storage box X1 according to the present embodiment on the side of the upper surface 1 U, Fig. 2 is a perspective view showing the sanitary napkin storage box, 3 is a perspective view of the sanitary napkin storage box X1 according to the present embodiment on the side of the bottom surface 1B, and Fig. 4 is a perspective view showing a state when the hinge cover portion of this embodiment is used.

The sanitary napkin storage box X1 of this embodiment comprises a paper box 1 having a ring-shaped sewing eye 11 on the upper surface thereof, a resin film 2 covering the sewing line inside range 11a from the inside ).

The paper box 1 is a box body made of paper in the form of a rectangular parallelepiped which forms the outer shape of the sanitary napkin storage box X1 and its size, shape and development shape are adopted in the structure of a paper box of a sanitary papermill storage box can do.

Side side face piece and a top side side sectional piece which are connected to both side edges of the respective sides in the longitudinal direction of the respective side faces, A structure in which the upper face side cross-section piece and the bottom face side cross-section piece are folded and bent, and the portions where the respective pieces are abutted with hot-melt adhesive or the like are typical.

On the other hand, the paper box 1 of this embodiment is printed on its outer surface in a suitable shape. In the illustrated example, a plurality of flower images 1b, 1b ... are arranged so as to be dotted so as to be arranged in a floral pattern, but the shape is not limited to this flower pattern but may be a spiral shape, a single shape of a suitable character, a figure, a figure, and a symbol such as a dot shape, a turtle shape, a star shape, a cross shape, and a geometric shape, or a combination thereof can be adopted.

It is preferable that the range for arranging the shape is disposed entirely on the outer surface of the paper box, but only the upper surface 1U may be used.

The shape of the outer surface of the paper box can be given by a known printing method such as gravure printing.

On the other hand, the annular sewing eye line 11 formed on the upper surface 1 U of the paper box 1 is formed by a known method, and the specific shape of the range 11a surrounded by this is also not limited Do not. Conventionally known shapes can be adopted. Specifically, as shown in the drawing, a generally elliptical shape having long sides in the longitudinal direction of the upper surface of the paper box is typically employed.

On the other hand, the resin film 2 is larger than the size of the dispensing opening 2 (the area 11a surrounded by the sewing line), and is, for example, a quadrangle and is adhered to the inner surface side of the upper surface of the paper box 1 with an adhesive .

The slit 21 of the resin film 2 is located in a range 11a surrounded by the sewing eye and the range 11a surrounded by the sewing eye along the looping sewing eye 11, The resin film 2 and the slit 21 formed in the resin film 2 are exposed between the blowing out ports 12 as shown in Fig.

In the paper box 1, the type of the adhesive used for the bonding is not particularly limited. Suitably, an aqueous adhesive is preferred in terms of recycling.

The length of the slit 21 is preferably shorter than the entire length in the longitudinal direction of the blow-out port 12, but may be equal to the entire length in the longitudinal direction of the blow-out port 12, It may be longer than the entire length in the long direction of the blow-out port 12 under a short condition.

The adhesive force (peel strength) between the paper box 1 and the resin film 2 is not particularly limited. The adhesive strength between the paper box 1 and the resin film 2 in the conventional product may be the same.

A suitable material for the resin film (2) is a polyethylene film, but polypropylene, polyester and the like are also exemplified.

A thickness of 30 to 200 mu m is suitable. If it is less than 30 μm, the strength is insufficient, and the probability of tearing or breaking is high when the tissue paper is taken out. On the other hand, if it exceeds 200 μm, there is no problem of strength, but it becomes difficult to take out and it becomes high cost.

On the other hand, the sanitary napkin storage box X1 of the present embodiment is in contact with the substantially center of the bottom surface 1B of the paper box 1 by a common sewing eye line 31, And having non-common sewing lines 32 and 32 arranged side by side thereon and having openings 33 and 33 which are parallel to each other and which are formed at the ends thereof, And has two refracting pieces 30,

Even when the amount of remaining tissue paper is reduced by pushing the refracting pieces 30 and 30 to the inner surface of the box, the upper surface of the bundle of tissue paper is positioned near the outlet so that the deterioration of the take-out property is eliminated.

The sanitary napkin storage box X1 of the present embodiment has a hinge 41 which partly covers one side of the ridge line between the bottom surface 1B and the side surface, which is characteristic of the bottom surface 1B of the paper box 1, And a hinge cover 40 formed by a sewing line 42 extending from both ends of the hinge 41 toward the ridge on the opposite side parallel to the hinge.

In the illustrated example, the hinge 41 is the central portion of the long ridge 1 L of the paper box 1, but the short ridge may be a hinge, for example.

The sewing line 42 constituting the hinge cover 40 of the present embodiment has an arc shape in which the lid free end side opposite to the hinge 41 is protruded, And has a cut end 43.

The hinge cover 40 is provided with the bent portions 30 and 30 and the sewing lines 41 and 43 and the bent portion 30 constituting the hinge cover 40 The sewing eyes 31 and 32 are discontinuous.

Therefore, the refracting pieces 30 and 30 and the hinge cover 40 can be formed by cutting the sewing eyes separately, and there is almost no possibility that the sewing lines of the sewing machines are unconsciously opened during the opening work .

The hinge cover 40 is a simple operation in which the fingers are caught by the ridges by pushing the scraped end portions 43 with fingers and the hinge cover 40 is pulled up so as to open the sewing eyes 42 in this state The sewing eye 42 is opened.

When the sewing line 42 is thus opened, the lid 40F of the hinge 41 is formed, irrespective of the presence or absence of the formation of the refracting pieces 30, 30, The opening (1 W) is formed in the bottom surface of the box by opening the cover (40 F) with which the inside of the box is accessible.

Here, the hinge cover 40 may be formed by inserting a hand into the inside of the box to take out an appropriate amount of tissue paper bundles, or after removing all of the tissue paper from the outlet, and then disposing the sanitary napkin storage box, It is preferable to set the length of the hinge 41 to be about 85 to 240 mm, because it is for the purpose of forming the opening used for holding the film. When the length of the hinge is 85 mm or less, it is difficult to insert the hand when the resin film is taken out. If it is 240 mm or more, it is difficult to open the sewing eyes.

The distance between the hinge of the sewing eye 42 and the opposite ridge line is preferably 65 mm or less. If it is 65 mm or less, it is difficult to form an opening having a size to hold a hand when the resin film is pulled out.

It is preferable that the hinge 41 is 1/5 to 2/3 of the ridgeline. If the hinge is 1/5 or less of the ridge, it is difficult to remove the bundle of tissue paper at once. When the hinge is more than 2/3 of the ridge line, when the lid 40F is opened, the bundle of tissue paper inside is not held by the portion of the bottom surface 1B that is not covered with the lid 40F, Tissue It is easy to get out of a bundle of paper. And is particularly suitable when the entire tissue paper bundle inside is not taken out.

The above-described sanitary napkin storage box X1 accommodates a tissue paper bundle in which a plurality of tissue papers are piled up in a so-called pop-up manner, as shown in Fig. 2, ) Are taken out one by one to form a part of a kind of tissue paper product to be used.

The size, paper thickness, number and composition of the tissue paper (P) itself are not limited in the present invention. In addition, the tissue paper (P) can be produced according to a known papermaking technique of papaya leaf paper.

The grassland has at least three parts, for example, a wire part that forms a grassland material substantially as a wetland, a press part that dehydrates the wetland, and a dryer part that dries the dehydrated wetland, have.

Suitable paper weights for tissue paper are, for example, 10 to 40 g / m 2 (JIS P 8124), suitable paper thicknesses are 25 to 800 μm, suitable dry tensile strengths are 150 to 800 cN / Width 15 mm x 250 mm, transverse direction 50 to 400 cN / width 15 mm x 250 mm (JIS P 8113). The suitable softness is 0.5 to 6.0 g (JIS L1096), the MMD is 3 to 18, and the elongation is 5 to 40%.

The preparation of the tissue paper bundle can be carried out by a known method of folding and overlapping the tissue paper paper by a known inter holder and then cutting it to a predetermined size.

Further, in the present invention, the height or the size of the tissue paper bundle is not particularly limited, and can be appropriately changed according to the size of the sanitary napkin storage box to be accommodated.

When all the tissue paper P housed in the sanitary napkin storage box is taken out and the use is finished, the sewing eyes 42 and 43 constituting the hinge cover 40 are opened to cover the cover 40F And the lid 40 F is opened to access the inner surface of the paper box. The resin film 2 is peeled from the paper box with the end of the resin film 2.

When the user wishes to take out the tissue paper in a bundle, the lid 40F is formed irrespective of the opening of the sewing eyes 31 and 32 constituting the refracting piece portions 30 and 30 so that the tissue paper in the sanitary napkin storage box Take out the bundle.
