[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a case, and in particular, is a simple case for storing stationery such as writing instruments, rulers, notebooks, documents, and other small items, and is used for carrying or displaying these small items. It can be related to the case.
[0002]
[Prior art]
A case 60 as shown in FIGS. 2 and 7, which includes a rectangular parallelepiped case main body 1 having an opening 3 on one end face 11 and a lid 2 for closing the opening 3, has been conventionally known. 2 and 7 show that the case 60 is placed on a flat support surface 50 such as the upper surface of a desk with the opening 3 closed by the lid 2. FIG.
In the case 60, the case body 1 and the lid 2 are the same material and are integrated. In this case 60, a synthetic resin sheet such as a thin polypropylene is first cut into a developed shape of a rectangular parallelepiped, and then bent at a position where it hits a side, and a predetermined portion is adhered to form a rectangular parallelepiped, thereby accommodating the accommodating space 30 therein. It is possible to maintain a substantially constant outer shape while allowing a certain degree of deformation due to an external force. As the material, transparent synthetic resins such as polypropylene, polyethylene terephthalate, and polyvinyl chloride are often used so that the contents can be visually recognized.
[0003]
The case main body 1 has the entire end surface 11 as an opening 3 corresponding to the entrance of the accommodation space 30, and the other surface 12 of the case main body 1 is cut into an insertion slot by cutting the surface 12 into a slit shape. 38 (an engaged tool) is formed. In the vicinity of the end of the lid 2, as shown in FIG. 5, an insertion portion 35 (engagement tool) is provided by dividing the tongue-shaped portion by making a cut 37 in the lid 2. The insertion portion 35 has a shape and size that can be inserted into the insertion port 38.
[0004]
The lid 2 is continuous with the case body 1 at a side 21 where the surface 13 facing the surface 12 contacts the end surface 11, and is substantially perpendicular to the surface 13 with the side 21 as a fold 6. The width of the lid 2 is substantially equal to the length of the side 21. The lid 2 is further bent at a substantially right angle at the crease 7. The lid 2 has elasticity, and the bending angle at the folds 6 and 7 is easily changed by the power of the user's hand. The interval between the crease 6 and the crease 7 is equal to or slightly wider than the interval between the side 22 and the side 21 facing the side 21 on the end surface 11. The interval between the base of the insertion portion 35 provided at the end of the lid 2 and the crease 7 is equal to or slightly wider than the interval between the side 22 and the insertion opening 38.
When the insertion part 35 is inserted into the insertion port 38 and engaged, the part A between the crease 6 and the crease 7 in the lid 2 closes the opening 3, and the part B between the crease 7 and the insertion part 35. Overlaps the surface 12 of the case body 1.
[0005]
In order to store the storage of writing instruments, documents, notebooks, small items, etc. in the storage space 30 in the case body 1, the insertion part 35 is removed from the insertion port 38 and the lid 2 is deformed in the direction to open the folds 6 and 7. Then, the opening 3 is opened, and the contents are put into the accommodation space 30 from the opening 3. After the contents are placed in the accommodation space 30, the opening 3 is closed by the lid 2 if the insertion part 35 is inserted into the insertion port 38 and engaged.
When carrying the case 60, the case 60 is usually directly held by hand with the opening 3 on the upper side, or placed in a bag or the like. Moreover, when using the case 60 when transporting commodities such as writing instruments from the factory to the store, the opening 3 is placed on the upper side or packed in a cardboard box.
Further, when displaying products, the case is kept in a standing posture or an oblique posture with an instrument or the like and placed on an exhibition stand or the like.
[0006]
In the case 60, even if the opening 3 is on the lower side, the lid 2 is locked to the case main body 1 by the insertion portion 35 and the insertion port 38, so that the items accommodated in the accommodation space 30 are easy. Never go out.
When taking out the contents, first, the insertion portion 35 is removed from the insertion port 38. Next, the lid 2 is deformed again to open the opening 3, and a necessary accommodation is taken out from the opening 3 by putting a hand into the accommodation space 30. Alternatively, the side of the opened opening 3 is lowered, and the place where the contents slide down to the opening 3 side is taken.
[0007]
The insertion portion 35 and the insertion port 38 correspond to an engagement tool and an engagement tool for engaging the end of the lid 2 with the case body 1. The thing by shape and structure is also known.
For example, FIG. 6 shows an engaging tool 45 and an engaged tool 48 having other shapes and structures in a state where they are separated. The engagement tool 45 is attached to the end of the lid 2. As the attachment means, known means such as screwing, scissors, etc., are used which are caulked on the back side through a part of the engagement tool 45 through a small hole (not shown) opened in the lid 2. The engagement tool 45 has an elastic piece 47 that rises obliquely from the frame portion 46. The engaged tool 48 is attached to the surface 12 (not shown) by a known means similar to the engaging tool 45, and has a base 49 and a gate-shaped member 50.
The front end of the frame part 46 of the engaging tool 45 is placed on the base 49 of the engaged tool 48, and the engaging tool 45 is elastically deformed by applying a further force to the engaging tool 45 and pulling the lid 2 to be elastically deformed. When moved to the 48 side, the elastic piece 47 passes through the gate-shaped member 50 while being elastically deformed once, and returns to its original shape when the elastic piece 47 finishes passing through, so that the engaging tool 45 engages with the engaged tool 48. To release this engagement, if the elastic piece 47 is pushed with a finger so that it can pass through the portal member 50, the lid 2 returns to its original shape due to its elasticity, so that the engaging tool 45 is engaged. Move away from the tool 48.
In addition to an engaging tool and an engaged tool using such an elastic piece, various shapes and structures such as a snap are known.
[0008]
[Problems to be solved by the invention]
The above-mentioned conventional case can be carried with a container with a light weight and simple structure, but since the container must be taken in and out while deforming against the elasticity of the cover, the cover becomes an obstacle, It was inconvenient especially when taking out.
In particular, when the case is used as a shipping case for goods, the store displays the goods together with the case, and the purchaser takes out the goods such as writing instruments from the case. However, in the conventional case, it is difficult to take out the goods.
Further, in the conventional case, in order to display the product together with the case, a device for standing the case or holding it in an inclined posture is required.
In view of the problems of the conventional case described above, the present invention is easy to use with a simple structure and does not obstruct the lid when taking in and out the contents, and also when taking in and out the contents even when used for transportation and display It is an object to be solved to provide a case that is easy and that does not require an instrument for holding the case.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a case 10 according to an embodiment of the present invention placed on a flat support surface 50 such as the upper surface of an exhibition stand with the opening 3 opened. The case 10 placed on the flat support surface 50 with the opening 3 closed by the lid 2 is exactly the same as the conventional case 60 shown in FIG. The figure is diverted by replacing 60 with case 10. 3 and 4 are side sectional views of the case 10 in the state shown in FIGS. 1 and 2, respectively. In these drawings, the same or similar parts as those in the conventional example are indicated by the same reference numerals.
[0016]
The case 10 also includes a rectangular parallelepiped case main body 1 having an opening 3 on one end face 11 and a lid 2 for closing the opening 3, and is the same as the case 60 according to the prior art in that it is not specified. .
That is, in the case 10, the case body 1 and the lid 2 are made of the same material and are integral. In this case 10, a thin synthetic resin sheet such as polypropylene is first cut into a developed shape of a rectangular parallelepiped, then bent at a position where it hits the side, and a predetermined portion is bonded to form a rectangular parallelepiped. The deformation can be maintained while maintaining a substantially constant outer shape.
In the case of carrying, it is the same as the conventional case 60 that usually holds the case 10 directly by hand or puts it in a bag or the like with the opening 3 on the upper side.
[0017]
In the case 10, two engaged tools are respectively provided on two opposing surfaces of the case body 1. That is, not only the insertion port 38 (engaged tool) is formed on one surface 12 by slitting the same surface into a slit shape, but also the surface 13 facing the same surface is slit. The insertion port 39 (engaged tool) is formed by cutting it into a long and narrow shape, and both the insertion ports 38 and 39 have shapes and dimensions into which the insertion part 35 (engagement tool) provided at the end of the lid 2 can be inserted. It is said that.
[0018]
If the insertion part 35 is inserted in the insertion port 38, the case 10 will be in the state of FIG. 2, FIG. This state is the same as the state in which the lid 2 of the conventional case 60 is closed, the opening 3 is closed by the lid 2, and the lid 2 is locked by the insertion portion 35 and the insertion port 38.
[0019]
If the insertion part 35 is inserted into the other insertion port 39, the case 10 will be in the state of FIG. 1, FIG. In this state, the lid 2 is folded in the direction opposite to the state of FIGS. Since the lid 2 has elasticity, it remains almost original while being inverted.
The case 10 is in contact with the support surface 50 at a portion near the crease 7 of the lid 2 and at the side 23 of the case body 1 (side opposite to the side 21 on the surface 13). As shown in FIG. 3, the side 21 of the case main body 1 is lifted from the support surface 50 by a portion A between the folds 6 and 7 of the lid 2 from the support surface 50 by the interval A between the folds 6 and 7. That is, it is inclined with the opening 3 side raised. That is, the case body 1 is supported diagonally on the support surface 50 by the lid 2.
[0020]
According to the case of the present invention, the lid 2 can be locked to the case main body 1 with the lid 2 open, so that the lid does not get in the way when the contents are taken in and out.
[0021]
In addition, the case body 1 can be placed obliquely with the opening 3 side raised on an exhibition stand, desk or the like with the lid 2 open. At this time, since the contents are brought close to the side 23 corresponding to the back of the accommodation space 30 due to their own weight, they do not come out of the accommodation space 30 from the opening 3 against the intention of the user.
When a new item is placed in the accommodation space 30 in the case body 1, the item is placed in the accommodation space 30 through the opening 3 and is released, and the item moves toward the back of the accommodation space 30 by its own weight. Because it slides down, accommodation is easy.
On the other hand, when the contents are taken out from the accommodation space 30, it is possible to put the hand into the accommodation space 30 from the opening 3 and grasp the contents, but the side 23 of the case body 1 is slightly lifted with one hand and accommodated in the opposite direction. The back side of the space 30 can be raised slightly, and the place where the contents have slid toward the opening 3 can be received by the other hand, and the opening 3 can be easily taken out together with the opening 3 being opened.
[0022]
In addition, since the case main body 1 is transparent, the contents can be visually recognized.
Therefore, when putting a writing instrument etc. in a case and putting it on a work desk or a study desk, combined with the ease of accommodation and removal of the contents as described above, take out only the minimum necessary items from the case 10. It can be used for work such as office work and learning, and when it is no longer needed, it can be easily returned to the case 10 for easy use. Therefore, there is an effect that the desk top does not become messy during work, which is particularly convenient for so-called desk work.
[0023]
Further, when displaying the product together with the case 10, it is convenient because the product in the case 10 can be visually recognized and the product can be easily taken out.
[0024]
1 and 3, the inclination angle θ when the case 10 is placed is not only the length of the case body 1, the distance between the folds 6 and 7 of the lid 2, but also the base of the engagement tool, that is, the insertion portion 35. And the crease 7, and the distance between the side 21 and the engaged tool, that is, the insertion port 39, the inclination angle θ can be set to a desired value by appropriately selecting these dimensions. . In addition, in order for the stored items to slide down toward the back of the storage space 30 in the case body 1 when stored, an article and a case body that are expected to be stored in the case 10 according to the use of the case 10 It is desirable to make the inclination angle θ larger than the friction angle between the inside and the inside.
[0025]
In the said embodiment, since the insertion part 35 and the insertion port 38 were used as an engaging tool and a to-be-engaged tool, there exists an advantage that manufacture is very easy. However, the engaging tool and the engaged tool of the present invention are not limited to this, and as other embodiments, various shapes conventionally used for this type of case such as the one shown in FIG. The engaging tool and the engaged tool can be used as they are. Various known means such as a hook and an annular member, a magnet, and a hook-and-loop fastener can be used.
[0026]
The engagement tool is preferably provided near the end of the lid because the end of the lid is stable when the opening is closed, but it is not always necessary to do so, and it may be provided in the middle of the lid. A plurality of lids may be provided.
[0027]
Although it is simplest to provide the engaged tools on the two surfaces facing each other, it is not always necessary to provide the engaged tools on the two surfaces facing each other. For example, the engaged tools are provided on the side surfaces in the postures of FIGS. It is also possible to provide a portion where the side surface bends to the lid and provide the engaging tool there. Moreover, you may provide in three or more surfaces.
[0028]
The opening may be a part of the end face, not the entire end face.
Moreover, although it is easiest to produce the case main body in a substantially rectangular parallelepiped shape, other shapes may be used depending on the application.
[0029]
The case body and the lid may be separate, and therefore may be made of different materials. The case body may be a hard material, and hard synthetic resin, metal, wood, etc. can be used as the material. The lid is only required to have appropriate elasticity, and may be a thin hard synthetic resin or metal, or a soft synthetic resin or cloth reinforced with metal to give elasticity.
However, if the case body and the lid are integrated as in the above embodiment and the material is a thin transparent synthetic resin having elasticity, it is easy to manufacture and has sufficient strength while being lightweight. Can also be visually recognized. Among transparent synthetic resins, polypropylene is particularly recommended because of its resistance to repeated bending stress, lightness, chemical resistance, heat resistance, and the like.
[0030]
【The invention's effect】
According to the case of the present invention, the lid can be locked to the case main body with the lid open, so that the lid does not get in the way when the contents are taken in and out.
Further, since the case main body can be placed obliquely on a horizontal surface with the opening side being raised, the posture of the case can be maintained without requiring a special instrument. Furthermore, the case of the present invention has an effect that it can be easily put in and out by placing it on an exhibition stand or a desk with the lid open.
According to the case having a transparent part on the case body, the contents can be visually confirmed, so the case is placed on the desk while the contents are housed in the case body, and only the minimum necessary items are taken out from the case for office work. It is easy to take a method of use that is used for work such as learning or purchasing the minimum necessary items and returning them to the case when they are no longer needed.
