Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic box provided with a bottomed box body having an open upper side and a lid body provided separately from the box body to close the upper side opening of the box body.

Traditionally, it is customary to send gifts at birthdays of children and grandchildren, at celebrations such as Seventy-three celebrations and weddings. When gifts are gifted, the gifts are packed, but a packaging box is used for packaging the gifts.

It is known that this cosmetic box has a box body with a bottom whose upper side is opened and a lid body which is provided separately from the box body and closes the upper side opening of the box body. Accordingly, an inner frame is put inside the box, and the plurality of gifts are arranged and sorted by the inner frame, so that the gifts can be beautifully stored (for example, see Patent Document 1).

Then, after the gift is stored in the box, the upper opening of the box is covered with the lid, and the periphery of the lid is attached to the box with adhesive tape or the like. The packaging box is further packed with a wrapping paper to prevent the lid body from being accidentally detached from the box body and opening the upper opening of the box body.

Utility model registration No. 3129303

However, in order to attach the lid body that covers the upper opening of the box body with the adhesive tape, the lid body must be surely closed with the upper opening side of the box body, and the adhesive tape is kept in that state. Since it was necessary to accurately attach the label to the regular position, and the need to attach it accurately, there was still a problem to be solved that the attachment work was relatively time-consuming.

In addition, attaching a lid that covers the upper opening of the box with adhesive tape requires adhesive tape in addition to the cosmetic box, increases the types of materials required for packaging, and reduces the unit price for packaging gifts. There is also the problem of pushing up.

An object of the present invention is to provide a cosmetic box that can easily lock the lid body that closes the upper opening of the box body to the box body.

Another object of the present invention is to provide a cosmetic box that can lock the lid to the box without using an adhesive tape.

The present invention relates to a box body having an upper opening having a peripheral wall that is raised from the periphery of a rectangular bottom plate to surround the upper surface of the bottom plate, and a top plate from the periphery of a rectangular top plate that closes the upper opening of the box body. And a lid having a side wall that extends downward so as to surround the lower surface of the box and has a side wall that overlaps from the outside with a peripheral wall in a state where the top plate closes the upper opening of the box.

The characteristic structure is that the locking pieces protruding from the leading edge of the side wall are formed on the sidewalls at the opposite positions of the top plate, and the top plate is folded back at the leading edge of the side wall with the upper opening of the box closed. There is a notch or an elongated hole formed in the peripheral wall through which the locking piece can enter.

In this cosmetic case, when the side wall includes an outer wall that is bent from the periphery of the top plate so as to surround the lower surface of the top plate, and an inner wall that is folded back at the leading edge of the outer wall and overlaps with the outer wall, It is preferable to cut and raise a part of the inner wall to form the locking piece.

Further, the peripheral wall is provided from the periphery of the bottom plate so as to surround the bottom plate, and the inner peripheral wall that is folded back from the upper edge of the outer peripheral wall so as to face the outer peripheral wall with a predetermined gap. When it has, it is preferable to form a notch or an elongated hole in the outer peripheral wall, and it is preferable to make the height of the locking piece from the side wall larger than a predetermined interval between the outer peripheral wall and the inner peripheral wall. ..

Further, it is preferable that the locking piece has an arcuate shape or a polygonal shape such that the width thereof becomes smaller toward the tip. It is further preferable that the engaging piece that has entered the notch or the long hole in a state where the opening is closed contacts the both sides of the notch or the long hole.

When the cut is formed in the peripheral wall, it is preferable that the cut has a straight part parallel to the bottom plate and short side parts extending from both ends of the straight part toward the bottom plate.

In the cosmetic box of the present invention, since the notch or the long hole through which the locking piece folded back at the tip end of the side wall of the lid can enter is formed in the peripheral wall of the box, the locking piece enters the notch or the long hole. In the state where the locking piece faces the top plate, the locking piece cannot move upward with respect to the peripheral wall of the side wall provided at the tip. Therefore, this makes it possible to easily lock the lid body that closes the upper opening of the box body to the box body without using the adhesive tape.

In addition, if the locking piece is formed by cutting and raising a part of the inner wall, the locking piece can be easily formed. If the cutout or the long hole is formed on the outer peripheral wall of the box, the locking piece that has entered the cutout can be formed. It is possible to prevent the gifts contained in the box from coming into contact with the gifts and hindering their entry.

If the locking piece has an arcuate shape or a polygonal shape in which the width becomes smaller toward the tip, the notch of the locking piece or the entry into the long hole should start from the narrow tip. It becomes possible to relatively easily enter the notch or the long hole, and the locking pieces that enter when the top plate of the lid blocks the upper opening of the box contact the both sides of the notch or the long hole. With such a length, it is possible to prevent the lid body locked to the box body from floating with respect to the box body.

If the notch formed on the peripheral wall has a straight part parallel to the bottom plate and short side parts extending from both ends of the straight part toward the bottom plate, the engaging piece entering the notch is cut by the notch. Since it is sandwiched, it is possible to prevent the locking piece from being easily separated from the notch.

Next, the best mode for carrying out the present invention will be described with reference to the drawings.

As shown in FIG. 1, a cosmetic case 10 of the present invention includes a box body 11 having a bottom with an open upper end, and a lid body 31 that closes an upper opening of the box body 11. The box body 11 has a rectangular bottom plate 12 and a peripheral wall 13 that is erected upward from the periphery of the bottom plate 12 and surrounds the upper surface of the bottom plate 12.

The makeup box 10 in this embodiment is a so-called forehead box, and as shown in FIG. 4, the peripheral wall 13 of the box body 11 surrounds the bottom plate 12 from the four side edges of the bottom plate 12. From the front, rear, left and right outer peripheral walls 13a, the top wall 13b folded back inward from the upper edges of the front, rear, left and right outer peripheral walls 13a toward the center of the bottom plate 12, and from the inner end edges of the top wall 13b. The front and rear left and right inner peripheral walls 13c are bent toward the bottom plate 12 and are opposed to the front, rear, left and right outer peripheral walls 13a with a predetermined gap w corresponding to the width of the top wall 13b. Such a box body 11 can be manufactured by bending a sheet-like material as a material.

FIG. 2 shows an unfolded sheet material 21 for a box for obtaining the box body 11. This box-shaped sheet-like material 21 includes a rectangular bottom plate 12, front and rear left and right outer peripheral walls 13a continuously provided from four side edges forming the outer periphery of the bottom plate 12 through first folds 22, and front, rear, left and right outer peripheries thereof. The top wall 13b connected from the edge of the wall 13a via the second fold 23 and the front, rear, left and right inner peripheral walls 13c further connected to the top wall 13b via the third fold 24 are shown. .. Here, the height H1 of the outer peripheral wall 13a and the height H2 of the inner peripheral wall 13c are formed to be substantially equal.

In FIG. 2, the support wall 13d is connected from the outer end edges of the front, rear, left, and right inner peripheral walls 13c via the fourth fold line 25, and both ends of the front, rear, left, and right outer peripheral walls 13a in the longitudinal direction are adjacent to each other. The sheet-like article 21 for boxes in which the reinforcing piece 13e continuous to the portion is formed via the fifth fold line 26, and the winding pieces 13f are formed from the left and right sides of the front and rear inner peripheral walls 13c via the sixth fold line 27, respectively. .. Then, a seventh fold 28 is further formed in the center of the reinforcing piece 13e.

As shown in FIG. 4, the box-shaped sheet-like material 21 is assembled by raising the outer peripheral wall 13a continuous from the periphery of the bottom plate 12 through the first fold line 22. Then, the top walls 13b continuous with the upper edge of the outer peripheral wall 13a via the second folds 23 are respectively bent inward, and the front, rear, left and right inner peripheral walls 13c connected to the top wall 13b via the third folds 24 are formed. Are further folded in the same direction, and the inner peripheral wall 13c is opposed to the outer peripheral wall 13a from the inside with a predetermined gap w corresponding to the width of the ceiling wall 13b.

Further, the support wall 13d further connected to the inner peripheral wall 13c is bent in the opposite direction by the fourth fold line 25, and the inner peripheral wall 13c is opposed to the outer peripheral wall 13a. It is polymerized in the surroundings to improve its strength.

On the other hand, in the reinforcing piece 13e shown in FIG. 2 that is continuously formed at the end of the outer peripheral wall 13a, when the front, rear, left, and right outer peripheral walls 13a are erected around the bottom plate 12, they are folded in two and inward. In the winding piece 13f shown in FIG. 2 which is formed from both the left and right sides of the inner peripheral wall 13c before and after being inserted, when the inner peripheral wall 13c is opposed to the raised outer peripheral wall 13a, the adjacent outer peripheral wall 13a and the inner peripheral wall 13c are adjacent to each other. The outer peripheral wall 13a, which has been raised, is prevented from returning to the original position by allowing the outer peripheral wall 13a to enter a predetermined gap w between the 13c.

As shown in FIG. 1, the box body 11 assembled in this way is provided with a peripheral wall 13 having an outer peripheral wall 13 a and an inner peripheral wall 13 c that are opposed to each other with a predetermined space therebetween. It will make up the forehead raised from the surroundings. Then, the peripheral wall 13 that surrounds the upper surface of the bottom plate 12 is opened to form an upper opening.

On the other hand, the lid body 31 that closes the upper opening of the box body 11 has a rectangular top plate 32 that closes the upper opening of the box body 11 and a lower part that surrounds the lower surface of the top plate 32 from the periphery of the top plate 32. Has a side wall 33 extending from the outside to the peripheral wall 13 of the box body 11 in a state where the top plate 32 covers the upper opening of the lid body 31.

The lid 31 can also be manufactured by bending a sheet material as a material. FIG. 3 shows an unfolded lid-shaped sheet 41 for obtaining the lid 31. The lid sheet-like material 41 includes a rectangular top plate 32, front and rear left and right outer walls 33a continuously provided from four side edges around the top plate 32 through first folds 42, and front and rear left and right walls thereof. The inner wall 33b on the front, rear, left and right is further provided continuously from the edge of the outer wall 33a through the second fold 43.

In FIG. 3, reinforcing pieces 33c for connecting both longitudinal ends of the front, rear, left, and right outer walls 33a to the ends of the adjacent outer walls 33a are formed through the third folds 44, and the left and right inner walls 33b for the front and rear are formed. Rolled sheet material 41 for lid in which winding pieces 33d are respectively formed from both sides via fourth folds 45, and polymerized pieces 33e are further formed from inner side walls 33b on the front, rear, left and right sides via fifth folds 46. Indicates.

A sixth fold 47 is further formed in the center of the reinforcing piece 33c so that the height h1 of the outer side wall 33a and the height h2 of the inner side wall 33b are substantially equal to each other.

In assembling the lid-like sheet-like material 41, as shown in FIG. 4, the outer wall 33a continuous from the periphery of the top plate 32 through the first fold line 42 is bent downward. Then, the front, rear, left and right inner side walls 33b connected to the outer side wall 33a are folded back in the same direction through the second fold line 43, and the outer side walls 33 are superposed from the inside, and the outer side wall 33a and the inner side wall are superposed on each other. A side wall 33 having 33b is provided so as to extend downward around the top plate 32 so as to surround the lower surface of the top plate 32.

Further, in the overlapped piece 33e further connected to the edge of the inner wall 33b, the overlapped piece 33e is bent in the opposite direction through the fifth fold line 46 and the inner wall 33b is overlapped with the outer wall 33a. 33e is polymerized around the top plate 32 to improve the strength around the top plate 32.

On the other hand, in the case of the reinforcing piece 33c shown in FIG. 3 that is continuously formed at the end of the inner wall 33b, the front, rear, left and right outer walls 33a are raised around the top plate 32, and the inner wall 33b is superposed thereon. When it is folded in two and inserted between the outer wall 33a and the inner wall 33b and formed on both left and right sides of the front and rear inner wall 33b, the winding piece 33d shown in FIG. 3 has the outer wall 33a and the inner wall 33b. When polymerizing 33b, it prevents the side wall 33, which is formed by the outer wall 33a and the inner side wall 33b, which are inserted between them and overlap each other, from returning to the original state.

In the lid body 31 assembled in this manner, the top plate 32 has a size corresponding to the outer shape of the peripheral wall 13 of the box body 11, so that the top plate 32 can be attached to the box body 11 as shown in FIG. With the upper opening closed, the side wall 33 extending downward from the periphery of the top plate 32 overlaps with the peripheral wall 13 of the box body 11 from the outside.

Here, the sheet-like material for box 21 shown in FIG. 2 and the sheet-like material for lid 41 shown in FIG. 3 can be manufactured by punching out a sheet-like material having elasticity and bendability using a die. Examples of the sheet-like material include various paper materials such as high-quality paper, coated paper, and recycled paper, and various resins including polyethylene resin, polypropylene resin, polyester resin, polycarbonate resin, polystyrene resin, acrylic resin, and the like. Examples include films.

Since the box-shaped sheet material 21 and the lid-shaped sheet material 41 are assembled and used as the box body 11 and the lid body 31, it is possible to withstand the strength of the box body 11 and the lid body 31. the relatively thick ones, for example, 220 g / m ² or more of, preferably it is preferred to use those ^{220g / m 2 ~240g / m 2} .

Returning to FIG. 1, the characteristic configuration of the cosmetic case 10 of the present invention is that a lid 31 has a top plate in which a locking piece 34 continuous from the leading edge of the side wall 33, that is, the lower end edge of the side wall 33 in the figure to the side wall 33. The notch 14 or the long hole, which is formed at a position opposite to each other 32 and into which the locking piece 34 folded back at the leading edge of the side wall 33 can enter while the top plate 32 covers the upper opening of the box body 11, has a peripheral wall 13. It is in the place where it was formed.

In this embodiment, since the lid sheet-like material 41 shown in FIG. 3 is assembled to obtain the lid 31, the side wall 33 of the lid 31 overlaps with the outer wall 33a at the leading edge as shown in FIG. The inner wall 33b is bent so that the inner wall 33b is bent. For this reason, as shown in FIG. 3, it is assumed that notches 34a that form locking pieces 34 that are continuous with the front and rear outer walls 33a are formed on the front and rear inner side walls 33b of the lid sheet material 41, respectively. ..

The notch 34a in FIG. 3 is formed in an arc shape having a second fold 43 between the outer side wall 33a and the inner side wall 33b as a start point and an end point at substantially the center in the longitudinal direction of the front and rear inner side wall 33b. The portion surrounded by the notch 34a and the second fold 43 is the locking piece 34.

Therefore, when the lid body 31 is assembled using the lid sheet material 41, the inner wall 33b is further folded back to the outer wall 33a bent around the top plate 32 to be polymerized. Even when the front and rear inner side walls 33b are folded back at the second fold 43, the locking piece 34 surrounded by 34a is not folded back and is separated from the inner side wall 33b by the notch 34a, and remains on the same surface as the outer side wall 33a. It is continuous with the outer wall 33a. That is, when the lid body 31 is assembled using the lid sheet material 41 shown in FIG. 3, the locking piece 34 is formed by cutting and raising a part of the inner side wall 33b.

Thus, although the notch 34a for forming the locking piece 34 is formed on the lid sheet 41, when the lid sheet 41 is formed by punching with a blade die, By attaching a blade for forming the notch 34a to the blade die, it becomes possible to form the notch 34a at the same time when the lid sheet material 41 is punched and formed, and the notch 34a is formed. It is possible to avoid increasing the unit cost of the lid sheet-like material 41 and increasing the unit cost.

On the other hand, in this embodiment, since the box-shaped sheet-like material 21 shown in FIG. 2 is obtained even in the box body 11, the peripheral wall 13 of the box body 11 has the bottom plate 12 from the four side edges of the bottom plate 12. It has an outer peripheral wall 13a raised so as to surround it, and an inner peripheral wall 13c opposed to the outer peripheral wall 13a from the inside with a predetermined distance w from the outer peripheral wall 13a.

Therefore, the notch 14 or the long hole into which the locking piece 34 can enter is formed in the outer peripheral wall 13a where the side wall 33 of the lid 31 is directly overlapped. In this embodiment, the notch 14 is formed in the outer peripheral wall 13a, and the notch 14 is a straight part 14a parallel to the bottom plate 12 and a short side extending from both ends of the straight part 14a toward the bottom plate 12. And a portion 14b.

As shown in FIG. 2, by forming the notch 14 in the box-shaped sheet-like material 21 in advance, when the box-shaped sheet-like material 21 is punched and formed by a blade die, the notch 14 is simultaneously formed. Is possible. Then, the step of forming the notch 14 after assembling the sheet-like material 21 for the box becomes unnecessary, preventing an increase in the step of forming the notch 14 and increasing the unit price of the box 11. It is possible to avoid such a situation.

Here, as shown in FIG. 8, since the lid 31 closes the upper opening of the box body 11, the top plate 32 thereof is formed slightly larger than the bottom plate 12 of the box body 11, and the top plate 32 is formed. The side wall 33 is formed so as to overlap with the outer side of the peripheral wall 13 of the box body 11 in a state where the upper opening of the box body 11 is closed. The height h of the side wall 33 is shorter than the height H of the peripheral wall 13, and the top plate 32 of the lid 31 closes the upper opening of the box 11 and is folded back at the leading edge of the side wall 33. The stopper 34 is configured to be able to enter the notch 14 or the long hole.

That is, the length L from the upper end of the peripheral wall 13 to the notch 14 is smaller than the height h of the side wall 33 so that the locking piece 34 folded back at the tip end of the side wall 33 enters the notch 14 or the long hole. Is formed. As a result, the locking piece 34 that is folded back at the tip edge of the side wall 33 and has entered the notch 14 faces the top plate 32 between the outer peripheral wall 13a and the inner peripheral wall 13c of the peripheral wall 13.

Further, although the height T of the locking piece 34 is formed shorter than the height h of the side wall 33, it is formed longer than a predetermined gap w between the inner peripheral wall 13c and the outer peripheral wall 13a. Then, as shown in FIGS. 9 and 10, the length D of the notch 14, that is, the length D of the straight portion 14a is made smaller than the width W of the arcuate locking piece 34 in contact with the side wall 33, and the lid 31 is formed. It is preferable that the arc-shaped locking piece 34 that has entered the notch 14 is in contact with both sides of the notch 14 while the top plate 32 of the notch is in contact with the upper end of the peripheral wall 13 of the box 11. ..

Specifically, as shown in FIG. 9, when the height H of the peripheral wall 13 of the box body 11 exceeds 35 mm, as shown in FIG. The height h of the side wall 33 is preferably about 20 mm, that is, in the range of 18 to 22 mm, and more preferably in the range of 19 to 21 mm, in order to relatively easily polymerize on the surface. The length L from the upper end of the peripheral wall 13 to the notch 14 is about 12 mm, that is, in the range of 10 to 14 mm so that the locking piece 34 folded back at the tip end of the side wall 33 enters the notch 14 or the long hole. It is preferable that it is in the range of 11 to 13 mm.

Further, the predetermined gap w between the inner peripheral wall 13c and the outer peripheral wall 13a is preferably about 6 mm, that is, a range of 4 to 8 mm, and more preferably a range of 5 to 7 mm, in order to secure its strength. preferable. Since the height T of the locking piece 34 is shorter than the height h of the side wall 33 and longer than the predetermined gap w between the inner peripheral wall 13c and the outer peripheral wall 13a, it is in the range of about 14 mm, that is, 12 to 16 mm. Is preferable, and the range of 13 to 15 mm is more preferable. Since the locking piece 34 is folded back by the operator's hand, the width W of the locking piece 34 continuous with the side wall 33 is about 60 mm, that is, 56 so that the locking piece 34 can be folded back by the three fingers of the worker. It is preferably in the range of to 64 mm, more preferably in the range of 58 to 62 mm.

Further, when the locking piece 34 has an arc shape, the length D of the cut 14, that is, the length D of the linear portion 14a, is set so that the locking piece 34 that has entered the cut 14 contacts both sides of the cut 14. It is preferably about 50 mm, that is, a range of 46 to 54 mm, and more preferably a range of 48 to 52 mm. Further, the length E of the short side portion 14b forming the cut 14 is preferably about 3 mm, that is, in the range of 2 to 5 mm.

By forming the locking piece 34 and the notch 14 in these ranges, the arc-shaped locking that has entered the notch 14 with the top plate 32 of the lid 31 in contact with the upper end of the peripheral wall 13 of the box 11. The pieces 34 can be easily brought into contact with both sides of the cut 14, and the locking piece 34 that has entered the cut 14 can be effectively clamped by the cut 14.

Next, packing of gifts using the above-mentioned makeup box will be described.

This cosmetic case 10 is particularly used for gifts, and includes a box body 11 having an upper opening, and a lid body 31 provided separately from the box body 11 to close the upper opening of the box body 11. Therefore, the gift is stored in the box 11, and then the lid 31 covers the upper opening of the box 11.

In order to cover the upper opening of the box body 11 with the lid 31, as shown in FIG. 4, the locking pieces 34 extending downward from the leading edge of the side wall 33, that is, the lower edge in the figure are spread in a direction away from each other. Then, the locking piece 34 is moved downward so as to crawl to the outside of the peripheral wall 13 of the box 11. Then, as shown in FIG. 5, the periphery of the top plate 32 is brought into contact with the upper end of the peripheral wall 13 of the box body 11, and the side wall 33 continuous with the locking piece 34 is overlapped with the outer peripheral surface of the peripheral wall 13 of the box body 11. Let As a result, the upper opening of the box 11 is sealed by the lid 31.

After covering the box body 11 with the lid body 31 in this manner, the lid body 31 is locked to the box body 11. In this locking, as shown in FIG. 6, the side walls 33 of the lid 31 are elastically spread outward while the locking pieces 34 that have been pushed outward are bent inward, and at the same time the box 11 is closed. The peripheral wall 13, in this embodiment the peripheral wall 13a, is tilted inward by its elasticity. Then, when the tip of the locking piece 34 reaches the notch 14, as shown in FIG. 7, the tip of the locking piece 34 is moved by the side wall 33 that is elastically restored and the peripheral wall 13 (outer peripheral wall 13a) that is being restored. The notch 14 is pushed open to enter the notch 14.

At this time, the engaging piece 34 enters the notch 14 relatively quickly due to the restoring force of both the side wall 33 and the peripheral wall 13, and the sliding noise is generated between the engaging piece 34 and the notch 14. The side wall 33 vigorously restores to the operator who manually bends the locking piece 34 inward. Due to such a sliding sound and a feeling that the side wall 33 vigorously restores, an operator who attempts to lock the lid 31 to the box 11 recognizes that the locking piece 34 has entered the notch 14. become.

Here, as shown in FIG. 9, since the locking piece 34 in this embodiment is formed in an arc shape such that the width W becomes smaller toward the tip, the locking piece 34 is cut into the notch 14. The entry starts from the tip with a narrow width, and it is possible to enter the cut 14 relatively easily.

As shown in FIG. 8, after the tip of the locking piece 34 has entered the notch 14, the side wall 33 and the peripheral wall 13 are restored, and the side wall 33 of the lid 31 comes into contact with the peripheral wall 13 of the box body 11 again. Then, the length L from the upper end of the peripheral wall 13 to the notch 14 is formed to be smaller than the height h of the side wall 33. Between the outer peripheral wall 13a and the inner peripheral wall 13c in, the sheet is bent toward the top plate 32.

In this way, when the locking piece 34 enters the notch 14 and faces the top plate 32, the locking piece 34 cannot move upward with respect to the peripheral wall 13 of the side wall 33 provided at the tip. Therefore, the lid 31 that covers the upper opening of the box 11 is locked to the box 11.

Particularly, since the locking pieces 34 are formed at the centers of the opposite sides of the top plate 32 of the lid 31, that is, at the symmetrical positions, the locking pieces 34 are formed on both sides of the box body 11, respectively. By entering the cuts 14 respectively, it becomes possible to lock the box body 11 on both sides of the lid body 31 in a well-balanced manner, and avoid a situation in which one side of the lid body 31 floats from the box body 11. You can

Since the peripheral wall 13 of the box body 11 has the outer peripheral wall 13a and the inner peripheral wall 13c bent so as to face the outer peripheral wall 13a at a predetermined interval, the locking piece 34 that has entered the notch 14 is formed. Will remain between the outer peripheral wall 13a and the inner peripheral wall 13c. Therefore, the locking piece 34 does not come into contact with the gift (not shown) housed in the box 11 to prevent the locking piece 34 from entering the notch 14.

Further, the height T of the locking piece 34 from the side wall 33 is set to be larger than a predetermined distance w between the outer peripheral wall 13a and the inner peripheral wall 13c, so that the locking piece 34 enters the notch 14 and heads toward the top plate 32. The piece 34 is prevented from turning toward the bottom plate 12 side of the box 11 between the outer peripheral wall 13a and the inner peripheral wall 13c, and the lid 31 is reliably prevented from coming off the box 11 due to this turning.

Here, the length L from the top wall 13b to the notch 14 in the peripheral wall 13 is made shorter than the height h of the side wall 33 so that the locking piece 34 folded back at the leading edge of the side wall 33 enters the notch 14. Therefore, the lid 31 is lifted from the box body 11 to the extent of the difference between the length L and the height h.

However, as shown in FIG. 10, when the arcuate locking piece 34 is used, its width W is made larger than the length D of the notch 14, and the top plate 32 of the lid 31 is attached to the peripheral wall of the box 11. By making the arc-shaped locking pieces 34 that have entered the notches 14 contact the both sides of the notches 14 while being in contact with the upper ends of the notches 13, the lid body 31 is prevented from floating with respect to the box body 11. It becomes possible to prevent it.

Then, as shown in FIGS. 8 and 10, when the cut 14 has the straight line portion 14a and the short side portions 14b on both sides thereof, both sides of the straight line portion 14a are deviated in the short side portion 14b, and the deviated straight line is formed. The locking piece 34 enters between the portions 14a. Then, the locking piece 34 that has entered the notch 14 is sandwiched by the notch 14, and the locking piece 34 is prevented from being easily separated from the notch 14, so that the lid 31 is carelessly inserted into the box body. This prevents the upper opening of the box body 11 from being opened by being detached from the box body 11.

As described above, according to the cosmetic case 10 of the present invention, the lid 31 that seals the box body 11 is locked to the box body 11 by a simple operation of folding back the locking piece 34 and entering the notch 14. It will be possible. Since the notch 14 and the locking piece 34 that has entered the notch 14 are covered by the side wall 33 of the lid 31, they do not appear on the appearance and do not deteriorate the appearance.

Further, by locking the lid body 31 to the box body 11, it is possible to prevent the lid body 31 from being unintentionally detached from the box body 11 and opening the upper opening of the box body 11 even during the distribution process. Therefore, in such a cosmetic case 10, it is possible to omit the pasting of the lid body 31 with an adhesive tape, which is conventionally performed to prevent the lid body 31 from coming off.

Then, when packing the gift, the adhesive tape, which has been conventionally required for locking the lid 31 to the box 11, is not required, and the kinds of materials required for the packing are reduced, so that the gift can be packed. It is possible to reduce the unit price. Since printing on the lid 31 is also possible, for example, if a design such as a wrapping paper is printed on the lid 31, it is possible to omit the packaging of the cosmetic case 10 with wrapping paper. ..

On the other hand, in the makeup box 10 of the present invention in which the lid body 31 is locked to the box body 11 as described above, in order to remove the lid body 31 from the box body 11, as shown in FIG. The side walls 33 of the body 31 are elastically spread to the outside, and the peripheral wall 13 of the box body 11 is tilted inward by the elasticity, and the locking piece 34 that has entered the notch 14 is pulled out from the notch 14. Then, as shown in FIG. 11( b ), the lid 31 is moved upward and removed from the box 11 in a state where the locking piece 34 is extracted from the notch 14, so that the upper opening of the box 11 is opened. Can be easily opened.

Further, since the locking piece 34 is formed by cutting and raising a part of the inner side wall 33b forming the side wall 33, when it is not necessary to lock the lid 31 to the box body 31, this locking piece 34 is used. By making 34 integral with the inner wall 33b without being cut and raised, it can be used as a normal lid 33 having no locking piece 34.

In the above-described embodiment, the case where the locking piece 34 that protrudes in an arc shape from the tip edge of the side wall 33 is formed has been described, but as long as the locking piece 34 can enter the notch 14, the locking piece 34 is It may be polygonal instead of arcuate. For example, it may have a trapezoidal shape as shown in FIG.

Even if the locking piece 34 has a polygonal shape, for example, a trapezoidal shape as shown in FIG. 12, the entrance of the locking piece 34 into the notch 14 starts from the tip thereof, so the width W thereof should be made smaller toward the tip. By this, it becomes possible to relatively easily insert the locking piece 34 into the notch 14 or the long hole, and when the top plate 32 of the lid 31 is in contact with the upper end of the peripheral wall 13 of the box 11, the notch 14 is inserted. The size of the polygonal engaging piece 34 that has entered makes contact with both sides of the notch 14 or the long hole, so that the lid 31 can be prevented from floating with respect to the box 11.

Further, in the above-described embodiment, the arc-shaped notch 34a is inserted into the inner wall 33b from the second fold 43 between the outer wall 33a and the inner wall 33b that form the side wall 33, and the second fold 43 is formed. Although a portion surrounded by the notch 34a and the cutout 34a is used as the locking piece 34, a separately provided locking piece 34 is adhered to the side wall 33 without forming the notch 34a so that the locking piece 34 is continuous with the side wall 33. The stopper 34 may be formed.

Further, although the case where the notch 14 is formed in the side wall 33 has been described in the above-described embodiment, it is not shown as long as the locking piece 34 can enter to lock the lid 31 to the box 11. Alternatively, the side wall 33 may be formed with a long hole into which the locking piece 34 can enter.

Further, in the above-described embodiment, the case where the peripheral wall 13 of the box body 11 has the outer peripheral wall 13a and the inner peripheral wall 13c bent so as to face the outer peripheral wall 13a with a predetermined gap therebetween has been described. .. However, if the locking piece 34 that has entered the notch 14 does not come into contact with the gift (not shown) housed in the box 11, it is necessary to provide the inner peripheral wall 13c. And not.
