Description

The present invention relates to a convenient article storage case that can be easily opened with one hand.

Conventionally, as a simple case capable of storing cosmetics, stationery, cards, etc., for example, as shown in FIG. 12 (a) and FIG. 12 (b) which is a cross-sectional view taken along the line XX'of FIG. 12 (a). Book-type cases are known (see Patent Documents 1, 2, etc.). In this case, a main body 3 having a recess 2 for storing articles on a sheet-like mount 1 having a crease, which is like connecting a book front cover, a spine cover, and a back cover, and an upper surface of the main body 3 It is attached with a lid portion 4 for covering the above.

The main body 3 and the lid 4 are each made of a pre-molded plastic molded product, and the lid 4 is closed by fitting the peripheral wall 4a of the lid 4 into the recess 2 of the main body 3. It has become like. It is also proposed that the fitting portion between the peripheral wall portion 4a of the lid portion 4 and the recess 2 of the main body portion 3 is provided with unevenness for locking so that the lid portion 4 does not easily open from the main body portion 3. (Not shown).

Such an article storage case is lightweight and convenient to carry, but when the lid 4 is opened, the side to which the main body 3 of the mount 1 is attached and the side to which the lid 4 is attached are separated from each other. , Each must be held and opened with the left and right hands. This operation is a little more troublesome than, for example, a compact cosmetic case in which the lid can be easily opened by simply pushing a hook provided in front of the container. Further, if the article storage case is vertically erected and the lid 4 and the main body 3 are opened to the left and right in the same manner as opening a book, the contents may be dropped down, which is a problem.

Therefore, even in such a book-type article storage case, it is being studied to hold the case horizontally with one hand and open it by a simple operation such as pushing the front, like a compact case for cosmetics.

However, for example, if the peripheral wall portion of the main body 3 is processed to incorporate a hook piece for opening and closing in the same manner as a compact case of cosmetics, the overall structure becomes complicated, the cost increases, and the weight also increases. As the number increases, the goodness of the book type case, which is simple and easy to carry, is lost.

The present invention has been made in view of such circumstances, and is an easy-to-use article storage case in which the lid can be easily opened with one hand while taking advantage of the simple, lightweight and inexpensive book type case. The purpose is to provide.

In order to achieve the above object, the present invention comprises a mount made of a strip-shaped sheet material, a main body portion attached to one end side of the mount and having a recess for storing articles on the upper surface, and a predetermined width of the mount. A lid portion that is attached to the other end side of the hinge and can cover the upper surface of the main body portion is provided, and a predetermined width region between the main body portion and the lid portion of the mount is the boundary with the main body portion and the lid portion. An article storage case that has a crease at the boundary with and is a hinge portion that can freely open and close the lid portion with respect to the main body portion, and the main body portion is a frame-shaped flat surface portion attached to the upper surface of the mount. The lid is composed of a thin-walled molded product having a peripheral wall portion rising from the flat surface portion in a frame shape and an upper surface portion having a recess for storing articles, and the lid portion is a frame-shaped flat surface portion attached to the upper surface of the mount. A hollow frame wall rising from the flat surface portion in a frame shape is provided, and the frame wall is folded inward from the frame-shaped outer peripheral wall portion and the upper end of the outer peripheral wall portion via a frame surface portion having a predetermined width. The inner peripheral wall portion of the frame wall has an inner peripheral wall portion extending downward, and the inner peripheral wall portion of the frame wall is made of a thin-walled molded product configured to be detachably fitted with the peripheral wall portion of the main body portion. , A part of the peripheral wall on the hinge part side bulges toward the hinge part side, and the part facing the hinge part of the bulging part becomes the first tapered part that inclines toward the inside of the peripheral wall part as it goes up. In addition, an engaging portion for locking the lid portion is provided on the side opposite to the hinge portion side, and the left and right sides of the frame wall portion extending to the hinge portion side of the frame wall of the lid portion are interrupted. The inner peripheral wall portion of the frame wall portion that is interrupted and independent becomes a second tapered portion along the first tapered portion on the main body portion side when mated with the peripheral wall portion of the main body portion. On the side opposite to the hinge portion side, an engaged portion that can engage with the engaging portion for locking the lid portion provided on the peripheral wall portion of the main body portion is provided, and the hinge portion is on the back side. When the lid and the main body are closed in the arrangement, the hinge portion is provided so that the edge of the mount on the side where the lid is attached is closer to the edge of the mount on the side where the main body is attached. Is inclined at a sharp angle with respect to the mount on the side to which the main body is attached, and the mount on the side to which the lid is attached is displaced toward the front side, so that the engaging portion provided on the peripheral wall of the main body is formed. The engagement with the engaged portion provided on the inner peripheral wall portion of the lid portion is disengaged , and the second tapered portion on the lid portion side slides diagonally upward along the first tapered portion on the main body portion side. The first gist is an article storage case that is configured so that the lid can be opened.

The second gist of the present invention is, in particular, an article storage case in which an extension portion extending from a flat portion of the lid portion is attached to a predetermined width region which is a hinge portion on the upper surface of the mount. The third gist is an article storage case in which an extension portion extending from a flat portion of the main body portion is attached to a predetermined width region which is a hinge portion on the upper surface of the mount, and the lid portion and the main body portion are mutually connected. The article storage case is composed of a series of thin-walled molded products connected by an extension portion extending from the flat surface portion of the above, and the extension portion is attached to a predetermined width region which is a hinge portion on the upper surface of the mount. This is the gist of 4.

Further, the present invention particularly provides an article storage case in which the inclination angles θ of the first tapered portion and the second tapered portion are set to 2 to 45 ° with respect to the vertical direction. It is the gist of.

That is, in the article storage case of the present invention, the main body and the lid for holding the article are each made of a thin-walled molded product, and these are attached to both ends of the hinge portion of the mount made of the strip-shaped sheet material. Due to its simple structure, it is lightweight and convenient to carry. Moreover, among the engagement portion of the main body portion and the lid portion, the predetermined portion of the hinge portion side, since the tapered portion inclined to each other, the boundary between the above hinge portion, the lid portion is attached portion When the crease is pushed out and the main body and the lid are displaced so that the hinge part is inclined at a sharp angle with respect to the mount to which the main body is attached, the main body and the lid are disengaged and the main body side. The tapered portion on the lid side slides diagonally upward along the tapered portion of the lid so that the lid can be easily opened . Therefore, this article storage case can be opened with one hand, which is convenient. Further, since this operation can be performed by holding the article storage case substantially horizontally, when the lid portion is opened, the article is not inadvertently dropped from the article storage portion of the main body portion.

Further, in the present invention, in particular, the extending portion extending from the flat portion of the lid portion is attached to a predetermined width region which is a hinge portion on the upper surface of the mount, or from the flat portion of the main body portion. If the extending portion is attached to a predetermined width region which is a hinge portion on the upper surface of the mount, the extending portion reinforces the crease portion which is the boundary portion with the hinge portion. Even if the portion is repeatedly bent, the crease is not torn or the shape of the entire hinge portion is not deformed, which is preferable.

Further, the lid portion and the main body portion are made of a continuous thin-walled molded product in which the lid portion and the main body portion are connected by an extension portion extending from each other's flat surface portion, and the extension portion is a predetermined hinge portion on the upper surface of the mount. Those attached to the width region are suitable because the extended portion reinforces the fold portions on both sides of the hinge portion, so that the fold portion and the hinge portion are more likely to be torn or lose their shape.

Further, among the present inventions, in particular, those in which the inclination angle θ of the first tapered portion and the second tapered portion is set to 2 to 45 ° with respect to the vertical direction are on the lid side of the hinge portion. The operation of pressing the crease portion of the lid to open the lid portion can be performed more smoothly, which is preferable.

It is a perspective view which shows the state which opened the part. Further, FIG. 3 is a plan view showing a state in which the article storage case is opened flat.

That is, this article storage case has a strip-shaped mount 10, a main body 11 attached to one end side of the mount 10, and a lid attached to the other end side of the central portion of the mount 10 with a predetermined width. It is provided with a unit 12. The portion of the mount 10 between the main body 11 and the lid 12 is the hinge portion 13, and the fold P provided at the boundary between the hinge portion 13 and the main body 11 and the lid 12 According to Q, the lid portion 12 is arranged in parallel with the main body portion 11, and the upper surface of the main body portion 11 can be covered or opened by the lid portion 12.

Explaining the article storage case in more detail, as shown in FIG. 3, the mount 10 is made of a strip-shaped sheet material having a rectangular shape in a plan view (in this example, a paper material having a thickness of 0.7 mm), and one end side thereof. A main body portion 11 made of a transparent thin-walled molded product (in this example, a molded product of a polyethylene terephthalate resin sheet having a thickness of 0.5 mm) having an uneven shape imparted by vacuum forming is attached. Further, a thin-walled molded product (similar to the main body portion 11 in this example, having a thickness of 0.5 mm) in which a concave-convex shape is also imparted to the other end side of the mount 10 across the portion serving as the hinge portion 13 by vacuum forming. A lid portion 12 made of a molded product of a polyethylene terephthalate resin sheet) is attached.

The main body 11 is a flat surface attached to the upper surface of the mount 10 as shown in FIGS. 4 (a) which is a right side view of FIGS. 3 and 3 and FIG. 4 (b) which is a front view of FIG. A flat surface portion 20 having a square frame shape, a first peripheral wall portion 21 rising from the flat surface portion 20 in a square frame shape, and a square frame shape slightly smaller from the first peripheral wall portion 21 via a stepped surface 22. It is provided with a second peripheral wall portion 23 that stands up.

Then, of the second peripheral wall portion 23, the hinge portion 13 side (the back side when the article storage case is used) is inclined toward the inside of the second peripheral wall portion 23 as it goes upward. The first tapered portion 24 is formed in a state of bulging on the stepped surface 22.

Further, of the stepped surface 22 between the first peripheral wall portion 21 and the second peripheral wall portion 23, the portion opposite to the hinge portion 13 side (front side when using the article storage case) is shown in the figure. As shown in 2, the central portion thereof is a low and concave arc-shaped curved surface 22a. A small recess 25 serving as an engaging portion for locking the lid portion 12 is provided at the center of the front surface side of the second peripheral wall portion 23 provided with the curved surface 22a.

An upper surface portion 26 extending in parallel with the flat surface portion 20 is provided inside the second peripheral wall portion 23, and recesses 27 and 28 for storing articles are arranged side by side on the upper surface portion 26. It is provided. The recess 27 on the left side is filled with foundation, and the recess 28 on the right side is filled with a puff for applying foundation and making up. The bottom surface 28a of the recess 28 is in contact with the mount 10 at a depth that is flush with the flat surface portion 20, and the bottom surface 27a of the recess 27 is slightly shallower than the recess 28 and is between the recess 28 and the mount 10. It has a gap. The band-shaped portion 26a, which is the boundary between the recesses 27 and 28, is recessed downward in an arc shape so that the puff can be easily taken out from the recess 28.

On the other hand, the lid portion 12 of the mount 10 provided on the opposite side of the main body portion 11 is FIG. 4A which is a right side view of FIGS. 3 and 3 and FIG. 4B which is a front view of FIG. As shown in the above, a flat surface portion 30 having a substantially square frame shape in a plan view, an outer peripheral wall portion 31 rising from the flat surface portion 30 in a square frame shape, and an upper end of the outer peripheral wall portion 31 attached to the upper surface of the mount 10. It is provided with an inner peripheral wall portion 33 that is folded inward and extends downward via a frame surface portion 32 having a predetermined width. A hollow frame wall 34 is formed by the outer peripheral wall portion 31, the frame surface portion 32, and the inner peripheral wall portion 33.

The flat surface portion 30 is provided with an extension portion 30a extending toward the hinge portion 13, and the extension portion 30a is attached so as to overlap the mount 10 constituting the hinge portion 13. Then, two perforations 50 are formed so as to sandwich the crease Q in the portion along the crease Q of the mount 10, and this portion can be easily folded back together with the crease Q of the mount 10. There is.

Further, inside the frame wall 34 of the lid portion 12, a frame-shaped bottom frame portion 35 having a gap between the lid portion 12 and the mount 10 is provided, and inside the bottom frame portion 35, the mount 10 is contacted. A bottom surface portion 36 in contact is provided.

The frame wall 34 is on the hinge portion 13 side, and both the left and right sides thereof are interrupted, and the inner peripheral wall portion 33 of the frame wall portion 34a that is interrupted and independent thereof is on the main body portion 11 side when fitted with the main body portion 11. A second tapered portion 37 having an inclined surface along the inclination of the first tapered portion 24 is formed.

Further, the frame surface portion 32 of the frame wall 34 on the side opposite to the hinge portion 13 (front side when using the article storage case) is curved on the main body portion 11 side when fitted with the main body portion 11. The curved surface 32a is curved in an arc shape so as to fit the curved surface 22a without a gap (see FIG. 2). Then, a small convex portion 38 is provided on the inner peripheral wall portion 33 extending inward from the curved surface 32a as an engaged portion capable of engaging with the small concave portion 25 provided in the second peripheral wall portion 23 of the main body portion 11. Has been done.

According to the above configuration, the frame of the lid portion 12 is formed by folding P and Q in the hinge portion 13 of the mount 10 in a valley fold so that the mount 10 on the lid 12 side and the mount 10 on the main body 11 side are parallel to each other. The wall 34 can be fitted onto the second peripheral wall portion 23 of the main body portion 11 to cover the upper surface of the main body portion 11. This state is shown in FIG. 4 (c), which is a cross-sectional view taken along the line YY'in FIG. Further, an enlarged view of the elliptical portion R surrounded by the alternate long and short dash line in FIG. 4 (c) is shown in FIG. 5 (a), and an enlarged view of the elliptical portion S is also shown in FIG. 5 (b). In addition, in FIG. 5A, the second peripheral wall portion 23 of the main body portion 11 and the frame wall portion 34a of the lid portion 12 are slightly elastically deformed by pressure contact with each other. (The same applies to the figure below).

As can be seen from these figures, in the state where the lid portion 12 is closed, the second peripheral wall portion 23 of the main body portion 11 and the frame wall portion 34a of the lid portion 12 are the first tapered portion 24 and the second, respectively. The tapered portion 37 of the above is fitted in a state of being pressed against each other. Therefore, as shown by an arrow in FIG. 5B, a small convex portion is formed on the engaging portion between the small concave portion 25 for locking the lid portion and the small convex portion 38 provided on the front side of the article storage case. The force that pushes 38 inward works, and the lid 12 does not open carelessly. Therefore, the fitting with the main body 11 is maintained in a stable state.

On the other hand, when opening the lid portion 12, as shown by the thick arrow in FIG. 4C, the thumb of the hand is placed on the edge of the mount 10 on the side where the main body portion 11 is attached to suppress the movement, and the hinge portion is suppressed. Use the index finger and ring finger turned to the 13 side to push the crease Q of the hinge portion 13 toward you. Then, when the hinge portion 13 is tilted so that the edge of the mount 10 on the side to which the lid portion 12 is attached is closer to the front side than the edge of the mount 10 on the side to which the main body 11 is attached, the main body 11 side The small concave portion 25 and the small convex portion 38 on the lid portion 12 side are disengaged so that the lid portion 12 can be easily opened.

That is, the crease Q of the hinge portion 13 is pushed out toward the front, and the mount 10 on the side where the lid portion 12 is attached is tilted at an acute angle with respect to the mount 10 on the side where the hinge portion 13 is attached. As shown in FIG. 6 ( b ), the small convex portion 38 for locking the lid portion provided on the front side of the lid portion 12 shifts toward the front side from the small concave portion 25 on the main body portion 11 side. To. Accordingly, as shown in FIG. 6 (a), along a first tapered portion 24 of the main body portion 11 side, the second tapered portion 37 of the lid portion 12 side sliding obliquely upward, as a result, the lid the frame wall portion 34a of the section 12 is Ru rides on the upper surface portion 26 of the main body portion 11. As a result, the lid portion 12 can be easily opened from the main body portion 11. This series of operations is continuously shown in FIGS. 7A to 7C. In FIG. 7, reference numerals other than the main reference numerals are omitted so that the operation can be easily understood.

As described above, in the article storage case, the main body portion 11 and the lid portion 12 are each made of a thin-walled molded product, and these are attached to both sides of the portion of the mount 10 made of paper material to be the hinge portion 13. Due to its simple configuration, it is lightweight and convenient to carry. Moreover, of the fitting portions of the main body portion 11 and the lid portion 12, the predetermined portions on the hinge portion 13 side are the first and second tapered portions 24 and 37 that are inclined to each other, so that the upper side of the hinge portion 13 is formed. The engagement between the main body 11 and the lid 12 can be easily disengaged by simply shifting the main body 11 and the lid 12 by pushing out (the portion of the crease Q) toward the front. Therefore, this article storage case can be opened with one hand, which is convenient. Further, since this operation can be performed by holding the article storage case substantially horizontally, when the lid portion 12 is opened, the article (in this example, a cosmetic puff or the like) is removed from the article storage portion of the main body portion 11. , Do not drop it carelessly.

Moreover, in the article storage case, since the extension portion 30a extending from the flat surface portion 30 of the lid portion 12 is attached to the hinge portion 13 of the mount 10, the extension portion 30a is the crease Q and its surroundings. Is reinforced. Therefore, even if this portion is repeatedly bent to open and close the lid portion 12, the crease Q is not torn or the shape of the hinge portion 13 is not deformed, and the lid portion 12 can be used satisfactorily for a long period of time.

In the above example, the inclination angle θ of the first tapered portion 24 provided on the main body portion 11 side and the second tapered portion 37 provided on the lid portion 12 side [inclination angle with respect to the vertical direction, FIG. 5 (a)] is preferably 2 to 45 °, and particularly preferably 10 to 30 °. That is, if the inclination angle θ is too small, it may be difficult to open the lid portion 12 smoothly, and conversely, if the inclination angle θ is too large, it becomes difficult for the pressure contact force between the two to be applied in the horizontal direction, and the lid The portion 12 may open carelessly, which is not preferable. If the inclination angles θ of the two are different from each other, the inclined surfaces of the hinge portions 13 are less likely to slide smoothly when the hinge portion 13 is inclined. Therefore, it is preferable that the inclination angles θ of the two are the same. By the way, in the above example, the inclination angle θ is 15 ° in both cases.

Further, in the above example, when the lid portion 12 is opened, the second tapered portion 37 on the lid portion 12 side rides on the flat upper surface portion 26 of the main body portion 11, but FIG. 8 (a) shows. As shown in the above, the lower end portion of the frame wall portion 34a (see FIG. 3) provided with the second tapered portion 37 is inserted into the portion of the main body portion 11 connected from the first tapered portion 24 to the upper surface portion 26. Article 40 may be provided. The hinge portion 13 side of the recess 40 is shallow.

Then, in order to open the lid portion 12, when the upper side of the hinge portion 13 (the portion of the crease Q, see FIG. 7) is pushed toward the front side in the same manner as described above, the lid portion 12 is lifted as shown in FIG. 8 (b). The frame wall portion 34a of the lid portion 12 is adapted to enter one end into the recess 40. Then, when the upper side of the hinge portion 13 is further pushed toward the front side, the frame wall portion 34a of the lid portion 12 comes out of the recess 40 and rides on the flat upper surface portion 26. As a result, the lid portion 12 can be opened wide.

In this way, if the recess 40 is provided on the upper surface 26 side of the main body 11 so that the frame wall portion 34a of the lid 12 is once inserted into the recess 40, the force for pushing the hinge portion 13 is suddenly applied. It is designed so that the entire case does not lose its shape due to excessive contact with the lid portion 12. However, it can be adjusted so that the entire shape is not lost depending on the angle of the inclination angle θ of the first and second tapered portions 24 and 37, the material and thickness of the mount 10, the main body portion 11, and the lid portion 12. It is not always necessary to provide the recess 40.

Further, from the same concept as in the case of providing the concave groove 40, for example, as shown in FIG. 9, a second tapered portion 37 is provided at a portion of the main body portion 11 connected from the first tapered portion 24 to the upper surface portion 26. A step portion 41 on which the lower end portion of the provided frame wall portion 34a (see FIG. 3) can be temporarily placed may be provided. It is preferable to set the height H of the step by the step portion 41 within the range of 0.1 to 1 mm. That is, if the step height H is too small, the effect of providing the step portion 41 may not be obtained. On the contrary, if the step height H is too large, the step portion 41 rides on the upper surface portion 26. This can be difficult and is not desirable. Of course, as in the example shown in FIG. 8, the step portion 41 is not always necessary.

Further, in the above example, an extension portion 30a extending from the flat surface portion 30 of the lid portion 12 to be attached to the mount portion 10 toward the hinge portion 13 side is provided and attached to the upper surface of the mount portion 10 together with the flat surface portion 30. The installation part 30a is not always necessary. For example, as shown in FIG. 10, the hinge portion 13 may be composed of only the mount 10. The portions of the main body portion 11 and the lid portion 12 to be attached to the mount 10 are shown by diagonal lines (the same applies to the following figures).

Further, as shown in FIG. 11A, an extension portion 20a extending from the flat surface portion 20 of the main body portion 11 to be attached to the mount 10 toward the hinge portion 13 side may be provided and attached together with the flat surface portion 20. In this case, it is desirable to provide a perforation 50'at the boundary between the extending portion 20a and the flat surface portion 20 which overlaps with the crease P.

Alternatively, as shown in FIG. 11B, the main body portion 11 and the lid portion 12 are made of a continuous thin-walled molded product in which the main body portion 11 and the lid portion 12 are connected by an extension portion 45 extending from the flat surface portions 20 and 30 of each other. The extension portion 45 and the flat portions 20 and 30 of each other may be attached to the upper surface of the mount 10. In that case, it is desirable to provide perforations 50 and 50'at the respective boundary portions overlapping the creases P and Q. The perforations 50 and 50'are formed so that one perforation overlaps the creases P and Q even if the two perforations are formed so as to sandwich the creases P and Q as in the above example. You may.

In the present invention, as the strip-shaped sheet material to be the mount 10, the paper material is used in the above example, but the paper material is not limited to the paper material, and various materials such as a plastic sheet and a composite sheet can be used. The thickness thereof is also appropriately set, but it is preferably set to, for example, about 0.1 to 2 mm. That is, if the thickness of the mount 10 is too thin, the strength of the case may decrease and the shape retention property may deteriorate. On the contrary, if the thickness is too thick, the opening / closing operation may not be smooth and the hinge portion 13 may not be able to perform. There is a risk that it will easily lose its shape due to excessive force.

Further, when characters or patterns are printed on the surface of the mount 10 (the surface exposed when the lid 12 is closed), those having a smooth surface and excellent printing characteristics are preferable. Of course, from a design point of view, a Japanese paper taste, a fluffy one, a one with an uneven pattern, or the like may be used.

On the other hand, the material of the main body portion 11 and the lid portion 12 made of the thin-walled molded product may be any resin sheet as long as the unevenness can be formed by molding. For example, in addition to polyethylene terephthalate (PET) used in the above example, thermoplastic resins such as polypropylene (PP), polyethylene (PE), and polystyrene (PS) can be mentioned. Among them, it is preferable to use recycled PET in terms of cost and resource saving. In addition, sheets and films of different materials are laminated on one side of the resin sheet material to increase the strength, and sheets and films with colors and patterns are laminated to make a case with a more impressive design. be able to.

The thickness of the resin sheet used for the main body 11 and the lid 12 is not limited to the above example, and is appropriately set depending on the material used, the size of the obtained article storage case, and the like, but is usually 0. It is preferable to set it in the range of 1 to 2 mm. That is, if the thickness is too thin, molding is not easy and it is not preferable in terms of shape retention. On the contrary, if the thickness is too thick, the entire article storage case becomes heavy, which makes it inconvenient to carry and is not preferable from the viewpoint of resource saving.

Further, as a molding method for obtaining the main body portion 11 and the lid portion 12 from the resin sheet, there are various molding methods such as vacuum forming, pressure molding, press molding, etc., in which the resin sheet is molded into an uneven shape. A molding method can be used.

Further, the mount 10 and the main body 11 and the lid 12 are usually bonded by using an adhesive, but depending on the material used, ultrasonic bonding or heat sealing may be used.

Then, in the present invention, the configuration for fitting and locking the main body portion 11 and the lid portion 12 is such that the first and second tapers 24 and 37 are provided on the hinge portion 13 side and the folds of the hinge portion 13 are provided. The other configurations are not particularly limited as long as the Q can be pushed toward the front.
