Abstract
Description
Technical Field
[0001] It relates to a mechanism for raising and lowering a plate inside a storage case.
Background Art
[0002] Conventionally, there are times when using a tissue paper without a cardboard box by putting it in a storage case. However, when using it in a tall storage case, when the remaining amount of the tissue paper decreases, the distance between the outlet of the storage case and the top of the tissue paper widens, resulting in a problem that the tissue paper falls into the storage case from the outlet.
[0003] When the tissue paper falls, there is a problem that it is necessary to deeply insert a finger into the outlet of the storage case to pick up and pull out the tissue paper, or to take out all the tissue paper in the storage case.

Summary of the Invention
Problems to be Solved by the Invention
[0005] The invention of JP-A-2003-327281 described in Patent Document 1 uses a means of placing a tissue paper on a pushing-up mechanism and storing it in a box. However, when the remaining amount of the paper decreases, the paper is sandwiched between the outlet of the box and the pushing-up mechanism where the spring exists, resulting in a problem that the paper cannot be smoothly pulled out.
[0006] The invention of Japanese Patent Application Laid-Open No. 10-194366 described in Patent Document 2 is a storage case provided with a lifting mechanism. A male screw is fitted into a bearing along the inner surface of the case, and a bottom plate is horizontally fixed near the end to a nut screwed onto the male screw, enabling the bottom plate to move up and down within the case as the male screw rotates.
[0007] However, there are problems of weight increase due to the components constituting the device. Along with this, there arises a problem of increased cost. Furthermore, there is also a problem that the lifting mechanism takes up space within the case. If possible, a simple structure is desirable, and the storage case is preferably compact, lightweight, and inexpensive.
[0008] The invention of Japanese Patent Application Laid-Open No. 10-167353 described in Patent Document 3 is a bottom-lifting type storage case. When the remaining amount of stored items such as tissue paper in the storage case decreases, the case is lifted and a hand is inserted into the bottom to perform a lifting operation. If possible, it is desirable to have a mechanism for performing the lifting operation from the outside of the case without lifting the case.
Means for Solving the Problems
[0009] The invention of claim 1 provides a plate for placing stored items inside the storage case, and by using a mechanism for lifting and lowering the plate, the problems of the patent documents and the conventional ones are solved. The lifting operation is configured to be performed from the outside of the storage case, simplifying the structure of the lifting mechanism and achieving lightweight.
Effects of the Invention
[0010] By providing a mechanism for lifting and lowering the plate on which the tissue paper existing in the storage case is placed, it is possible to set the distance between the outlet for taking out the lid of the storage case and the topmost part of the paper to a distance at which the paper can be easily pulled out. As a result, it is possible to prevent the paper from falling out of the outlet of the lid and obtain the effect of being able to smoothly take out the last sheet.
[0011] Furthermore, by using a storage case with a mechanism for raising and lowering the board while having a low production cost, and an inexpensive tissue paper without a cardboard box, an effect leading to savings and ecology can be obtained.

Modes for Carrying Out the Invention
[0012] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are examples for carrying out the present invention and are not intended to limit the present invention only to those embodiments. Further, the present invention can be variously modified without departing from its gist. Furthermore, the same reference numerals are given to the same components in each drawing as much as possible.
[0013] <Embodiment> Embodiments according to the present invention are shown in FIGS. 1 to 6. The storage case for putting tissue paper has a wooden lid, and the case and the parts of the lifting mechanism are made of synthetic resin. The storage case and parts of the embodiment are manufactured by an injection molding machine. Incidentally, although the tissue paper contained in a vinyl soft pack will be taken as an example for description, hereinafter it is referred to as "tissue paper".
[0014] As shown in FIGS. 1 to 6, it consists of a storage case 1 with a lifting mechanism (hereinafter referred to as "case 1"), a lid 2, an L-shaped plate 3 (hereinafter also referred to as "plate 3"), a concave portion 5, a convex portion 6, a male screw 7, and a knob 4 with a female screw 8 at the center (hereinafter referred to as "knob 4"), and an opening 9 where the male screw protrudes is provided on the side surface of the case 1. Note that the L-shaped plate 3, the convex portion 6, and the male screw 7 are integrated.
[0015] The embodiment realizes weight reduction while having a lifting mechanism, and solves the problem of weight increase due to the parts of the device, which is the problem of Patent Document 2. Furthermore, by setting the distance between the plate 3 and the lid 2 to a distance at which the tissue paper can be easily taken out, the problems of Patent Documents 1 and 3 and the conventional problems are solved.
[0016] The case 1 is a rectangular parallelepiped, and the outer dimensions are 120 mm in length, 210 mm in width, 90 mm in height, and 2.5 mm in thickness. The inner dimensions 15 of the opening 10 of the case 1 for fitting the lid 2 are 5 mm in depth and 1.5 mm in thickness. The longitudinal and lateral dimensions of the case 1 were determined with reference to the dimensions of the tissue paper contained in a commercially available vinyl soft pack. The case 1 is shown in FIG. 1.
[0017] The dimensions of the wooden lid 2 are 119 mm in length, 209 mm in width, and 5 mm in thickness. An opening 11 (35 mm in length and 100 mm in width) for taking out the tissue paper is provided at the center. As shown in FIG. 2.
[0018] Next, the concave portion (rectangular) 5 is introduced. A concave portion 5 with a length of 82.5 mm, a frame width of 10 mm, a groove width of 30.2 mm, and a groove depth of 4 mm is provided on the longitudinal surface inside the case. Further, an opening 9 with a width of 7 mm and a length of 65 mm is provided at the center of the bottom of the groove 13.
[0019] The uppermost part of the opening 9 is located 15 mm below the upper surface of the case 1, and the lower part is located 10 mm from the bottom of the case 1. Note that a little margin was given to the length of the opening 9. It is possible to confirm the remaining amount of the tissue paper existing on the plate 3 inside the case from the outside of the case 1 through the opening 9. The concave portion 5 and the opening 9 are shown in FIGS. 3 and 6.
[0020] Introduce the main role of the opening 9. When the convex part (square) 6 integrated with the plate 3 and the male screw 7 fits into the concave part 5 (square), the male screw 7 existing at the center of the convex part 6 is inserted into the opening 9, and it is configured to protrude outside the case 1 and engage with the knob 4 having a female screw. The opening 9 is a passage through which the L-shaped plate 3 introduced in
[0022] moves up and down with a tissue paper placed thereon.
[0021] Next, introduce the plate 3. The plane of the L-shaped plate 3 is the part on which the tissue paper is placed, and the dimensions are 90 mm in length, 160 mm in width, and 2.5 mm in thickness. An opening 12 with a length of 30 mm and a width of 70 mm is provided at the center. The opening 12 is provided for inserting a finger to grasp the plate 3 when the convex part 6 integrated with the plate 3 is attached to and detached from the concave part 5, and it has the effect of making the plate 3 easier to handle.
[0022] Next, introduce the I (vertical) of the L-shaped plate 3 which is a main component of the lifting mechanism of the present invention. The height of I (vertical) is 30 mm, the length is 160 mm, and the thickness is 2.5 mm. The convex part (square) 6 existing at the center of I (vertical) forms a rectangular parallelepiped, and the dimensions are 30 mm in length, 30 mm in width, and 4 mm in thickness. The convex part 6 has a male screw 7 with a full length of 7 mm and M5 at the center. The convex part 6 integrated with the plate 3 is shown in FIG. 4.
[0023] Here, state the reason for making the convex part 6 a rectangular parallelepiped. When a tissue paper is placed on the plate 3 integrated with the convex part, a load is applied to the plate 3. Therefore, in order to smoothly move the plate 3 up and down, it is considered that it is preferable that the area of the convex part 6 in contact with the groove 13 of the concave part 5 is large. The inventor adopted a rectangular parallelepiped after repeated trial and error. Note that the vertical and horizontal dimensions of the convex part 6 are 30 mm, but it is not limited.
[0024] Finally, introduce the knob 4 that fixes the male screw 7 protruding from the opening 9 from the outside of the case. The knob 4 is cylindrical, with a diameter of 30 mm and a height of 12 mm, and a female screw 8 with a depth of 8 mm and M5 is provided at the center. Note that the material of the lifting mechanism may be a light metal such as aluminum, and the case may be made of wood or metal. Also, the male screw 7 and the female screw 8 are M5, but it is not limited.
[0025] Next, the usage method of the embodiment will be described. As the tissue paper, use the one contained in the soft pack of the plastic bag. The dimensions are 110 mm in length, 190 mm in width, and 45 mm in thickness. First, insert a finger into the opening 12 of the plate 3 and grasp it, and fit the convex portion 6 into the concave portion 5 so as to show the shape of L.
[0026] At this time, the male screw 7 existing on the convex portion 6 is inserted into the opening 9 and protrudes 4.5 mm outside the case 1. Place the plate 3 fitted with the concave portion 5 on the bottom of the case 1 and fit the knob 4 onto the male screw 7. After that, pull out one sheet of tissue paper from the outlet of the soft pack and place it on the plate 3.
[0027] Next, set the plate 3 at a position where the tissue paper can be smoothly pulled out, and tighten and fix the knob 4. Finally, fit the lid 2 onto the case 1, and expose one sheet of tissue paper from the opening 11 of the lid 2 to finish. This is the operation of the lifting mechanism to be performed first. As described above, the lifting mechanism having the plate has a simple structure.
[0028] During use, when looking at the paper from the opening 9, when the remainder becomes about half, raise the plate 3 until it hits the lid 2. When this operation is performed, the distance between the plane of the plate 3 and the lid 2 becomes 30 mm.
[0029] Needless to say, the 30 mm is the dimension of I (vertical) of the plate 3 and is the depth at which the paper does not fall. The tip of I (vertical) of the plate 3 forming the L shape serves as a stopper when the plate is raised. Note that the operation of the elevator only needs to be performed twice, but it may be operated frequently.
[0030] This embodiment is characterized in that, by providing a mechanism for raising and lowering the plate 3 existing in the storage case, it is possible to prevent the tissue paper from falling from the outlet of the lid 2 of the case 1 and to set the paper at a distance at which it can be easily pulled out from the outlet of the lid 2. As a result, an effect that the last sheet can be smoothly pulled out can be obtained. The storage case of the present invention is unique.
[0031] In order to achieve the above effects, it is a condition that the plate 3 having an L shape, the convex portion 6, and the male screw 7 are integrated. It is also a condition that the convex portion 6 of the fitting body is a rectangular parallelepiped and the concave portion 5 is an oval quadrilateral. Note that the shape of the fitting body is not limited to the embodiment. For example, the convex portion may be cylindrical.
[0032] As the lifting means, a rack & pinion type, a rail slide type, a gear type, etc. were adopted for trial production. As a result, all of them satisfied the conditions as a lifting mechanism. However, it was judged that the fitting method adopting the plate having an L shape integrated with the convex portion was excellent, and thus the present embodiment was reached.
[0033] In addition, as a method for adjusting the distance between the lid 2 and the plate 3, a lifting operation mechanism was also prototyped in which a male screw was attached to a plate having a spring, vertical openings were provided on both sides (both sides) of the storage case, and the male screw was extended from the openings and fixed. However, since it is similar to [Patent Document 1], the present embodiment was reached.
[0034] According to the present invention, a convenient storage case can be obtained by combining a storage case having a height with a small item case for putting a TV remote control or the like and a lifting mechanism. Conventionally, when putting a tissue paper in a case having a height, it is necessary to raise the bottom inside the case, but this is not necessary in the embodiment. By providing a lifting mechanism, it is possible to provide several types of heights of the case.
[0035] The inventor invented the embodiment on the premise of using a tissue paper not contained in a cardboard box. This is because, in the case of a tissue paper having a cardboard box, there is a problem that it takes time and effort to disassemble the box and separate the vinyl at the outlet. It is expected that many people will use an inexpensive boxless tissue paper that does not require this, leading to savings and ecology.
