Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a powder gypsum storage box for storing powdered gypsum used as a dental material in a nearby location such as a technician's work room.

[Conventional technology]

Conventionally, powdered gypsum used in dental clinics, dental laboratories, etc. is sealed in waterproof flexible sheet bags and weighs about 18 kg. To use it, simply open the bag and use a hand shovel to scoop out the powdered gypsum inside the bag, but since the bag is flexible, the powdered gypsum may scatter due to the movement of air inside the bag each time it is opened or closed. This may result in the worker inhaling it, and the powdered gypsum that adheres to the inside of the bag may also adhere to the cuffs of the worker's clothing, etc., so lift it up each time you need it and put the required amount into another small container. After dispensing,
Currently, powdered gypsum is handled by storing it in sealed bags to prevent quality deterioration due to moisture absorption, or by transferring it from the bag to a can and then dispensing it.

[Problem that the invention attempts to solve]

However, with the method of dispensing from the bag, it is necessary to lift and take out the heavy bag each time, and scattering and floating of the powdered gypsum is still unavoidable.In addition, the powdered gypsum material is unstable when placed in a small container. In addition to being uneconomical as the liquid spills out of the container, there is also the disadvantage that the quality deteriorates unless the bag is reliably sealed each time.

In addition, although the latter method of transferring to a can ensures the convenience of dispensing after the fact, the gypsum powder scatters violently during transfer, and there are health concerns such as workers inhaling powdered gypsum floating in the room. There are inconveniences and the inconvenience of being deposited indoors.

Furthermore, in either case, there are disadvantages in that it is not only difficult to move, but also has a bad appearance, which harms the indoor environment.

The present invention was devised in view of the current state of the art as described above, and it prevents deterioration in the quality of powdered gypsum, minimizes the scattering and floating of powdered gypsum, and is movable to improve the workability of dispensing. The purpose is to provide a powder gypsum storage box that can be significantly improved at a low cost.

[Means for solving the problem] The feature of the present invention is that one caster is installed at the bottom.
A box main body 6 has a surrounding member 4 consisting of a support or a side plate that surrounds the storage space 3, and a support frame 5 is formed at the upper end opening on the upper surface of the support substrate 2 to which the storage space 3 is attached.
In addition, it is composed of a presser frame 8 having fitting legs 7 formed at the lower part thereof and hooked to the support frame 5, and a lid body 9 that closes on the presser frame 8.

[Functions and effects of the invention]

In the powder gypsum storage box of the present invention, a bag A containing powder gypsum is placed on the support substrate 2 in the storage space 3 and opened, and the periphery of the opened bag is inserted into the upper end opening of the surrounding member 4. After turning over and hanging the support frame 5 formed in the above, the presser frame 8 is overlapped,
The periphery of the opening of the bag is clamped and fixed between the inner surface of the support frame 5 and the fitting leg 7 of the holding frame 8, and the upper opening surface is closed with the lid 9 to place it in a predetermined position where it will not get in the way of a laboratory or the like. It is placed and used. When it is necessary to dispense, use the caster 1 to move the powder gypsum storage box to a predetermined position, then open the lid and remove the required amount of powder gypsum from the bag with a hand shovel.
After taking it out, put the lid 9 on and return it to its original position.

According to the present invention, the bag is stably stored with its peripheral side supported by the surrounding member, preventing it from falling over accidentally, and the open end of the bag A is supported by the support frame 5 and the holding frame 8. Since the bag is always kept wide open, the contents can be easily taken out without having to repeatedly open and close bag A. This eliminates the need for lifting heavy bags and dispensing as required in the past, which reduces the burden on the worker, and eliminates the scattering of powdered gypsum that occurs each time a bag is opened and closed, and the gypsum powder is sucked into the bag. It has the effect of eliminating health problems and indoor pollution that have occurred. Further, since the lid body 9 is placed on the support frame 5 in a crowned state, moisture is always blocked and quality deterioration due to moisture is eliminated. Furthermore, since a caster is attached to the bottom and it rolls,
It can be easily moved to any position without causing scratches on the floor surface, significantly improving work efficiency.

〔Example〕

The embodiments of the present invention will be illustrated and explained as follows.

In FIG. 1, a cylinder and a horizontal beam are used as the surrounding member 4 of the storage space 3. The cylinder is erected at the four corners of the upper surface of the support substrate 2 with the caster 1 attached to the bottom thereof, and in order to make the inner side of the frame rectangular, cutouts are provided at the positions facing each other diagonally. A support frame 5 is supported and fixed to. The presser frame 8 that overlaps with the support frame 5 has a flange projecting from the outer surface of the upper end of the fitting leg 7, which has a rectangular cylindrical shape and is large enough to be loosely inserted into the support frame 5. It is designed to be locked to the support frame 5.

The lid body 9 is deep enough to cover the flange of the holding frame 8, and has a handle 1 on the top surface.
0 is provided protrudingly, and the lid body 9 is opened and closed by gripping this handle.

In this embodiment, with the holding frame 8 removed, a bag containing powdered gypsum is lifted up to the open end of the holding frame 8 and placed therein.

FIG. 2 shows another embodiment in which the bag A can be stored in the storage space 3 from the side without having to lift it up high. For this purpose, one of the frame members of the support frame 5 is configured to rotate around a horizontal axis, and the surface on which this rotating frame member is located is in an open state without providing a horizontal bar.

FIG. 3 is a side view of a case in which the storage space surrounding member 4 is formed of a complete box made of plate material, and the lid 9 is hinged to open and close so that there is no need to remove each part. The periphery of the upper end opening of the storage space surrounded by the storage space becomes the support frame 5, and the presser frame 8 is fitted into this.

The above-mentioned powder gypsum storage boxes of the present invention are all rectangular, but they may also be cylindrical, and the materials used are as follows:
Synthetic resin materials, lightweight metal materials, etc. are used, but if necessary, plywood or wood may be used for the support substrate, or a combination thereof may be used selectively. Further, as for the surrounding member, any form may be used as long as it can stably support the bag in the storage space, and for example, a mesh plate or the like may be used.
