Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage container with good workability for taking out a dental photopolymerizable resin, and more specifically, it relates to a storage container for easily and accurately taking out a required amount of photopolymerizable resin. The present invention relates to a storage container for dental photopolymerizable resin, which is capable of stably storing the resin remaining inside the storage container over a long period of time without causing deterioration or the like.

In the following explanation, a case in which the dental photopolymerizable composite resin is used as a storage container will be described in detail as a representative example, but the storage object of the present invention is not limited to this example, and it can be used as a storage container for dental photopolymerizable composite resin. This also applies to materials.

[Prior Art] The product form of dental composite resins is classified into paste-like, ginseng type, and two-part type, in which a base and a hardening accelerator are mixed, and those belonging to the former. There is a photopolymerizable resin that polymerizes and hardens when exposed to visible light or ultraviolet rays.

FIGS. 4(a) to 4(c) are perspective explanatory views showing examples of storage containers for the photopolymerizable composite resin.

In FIG. 4(a), a relatively shallow dish-shaped container 2 is filled with composite resin 1, and a cap 3a is screwed onto a male thread 4 formed on the outer peripheral wall of the dish-shaped container 2 to seal it. Further, in FIG. 4(b), the composite resin is stored in a cylinder-shaped cylindrical container 5, the plunger 6 is inserted into the cylindrical container 5, and the flange 8b is inserted into the handle 8 of the cylindrical container 5.
It has a structure in which the resin in the cylindrical container 5 is pushed out from the container tip 5a by pressing it close to the a side. A removable cap 3b is attached to the container light@5a.

Furthermore, in FIG. 4(C), the plunger 6 is improved to have a screw shaft.

However, in the case shown in FIG. 3, once the cap 3a is opened, external light hits the entire surface of the resin 1 inside the container 2, and curing progresses while the required amount is taken out. Therefore, as the material is taken out several times, the remaining portion becomes hardened, and the remaining portion becomes completely hardened before the entire amount is used, which is extremely uneconomical. Alternatively, there may be cases where the cured material is forced to be used because it is considered a waste, and the therapeutic effect is no longer exerted.

On the other hand, when using the press-type cylindrical container 5 shown in FIGS. Container 5
Even if the residual pressure of the resin inside the container is increased and the pushing of the plunger 6 etc. is stopped, the resin 1 is pushed to the tip 5a of the container due to the residual pressure.
There is a tendency for resin to overflow from the container tip 5a and caps 3b and 3c, resulting in more than the required amount of resin being taken out.
There is also the problem that cured resin may adhere to the surface and cause contamination. In addition, it is extremely complicated to remove and attach the caps 3b and 3c each time the resin is taken out, or the caps 3b and 3c.

3c may be dropped from the workbench or lost, or the cap 3c may be lost.
Because the items b and 3c are small, they sometimes get mixed up with other treatment tools or material containers and get lost. Therefore, the removed caps 3b and 3c are sometimes left uncovered, and the resin 1 hardens and becomes occluded within the container tip 5a.
In some cases, the resin in the cylindrical container 5 could no longer be taken out.

[Problems to be Solved by the Invention] Therefore, the present inventors have made it possible to easily and accurately take out the required amount of photopolymerizable composite resin, and to prevent the resin remaining in the container from curing or other deterioration. The present invention was completed after repeated research with the aim of providing a storage container for dental photopolymerizable resin that can be stored for a long period of time without causing any damage and the entire amount can be used up without any problems.

[Means for Solving the Problems] The present invention, which has achieved the above objects, includes a cylindrical hollow inner container for storing a photopolymerizable resin, and a cylindrical hollow inner container rotatably fitted to the inner container. , and slits or holes are respectively formed on the peripheral wall surfaces of the inner container and the outer lid, and when the outer lid is rotated in the circumferential direction and the slits and/or holes match each other, The gist is that a resin extraction hole is formed that communicates the inside and outside of the inner container.

[Operations and Examples] FIG. 1 is a perspective explanatory view showing a typical example of the present invention. The storage container consists of an inner container 11 and an outer container i21, which are made of plastic, metal, inorganic material, or the like, and are made of a material that does not alter the quality of the photopolymerizable composite resin 1 housed inside. The inner container 11 is formed into a cylindrical shape with a bottom, and a slit 13 extending in the longitudinal direction of the axis of the waist portion is formed in the peripheral wall surface 11a at a height that prevents the resin stored therein from leaking. The one-sided i21 is formed in a cylindrical shape, and a planar end plate 22 is integrally formed on the top thereof, and a slit 24 extending from the lower side opening edge is formed in the peripheral wall surface 21a of the outer M21. The outer cover peripheral wall surface 21
The inner diameter of a is formed to be substantially concave with the outer diameter of the inner container peripheral wall surface 11a, and the peripheral wall surfaces 11a and 21a are fitted into each other,
It is configured to be rotatable in the circumferential direction.

The slit 13 of the inner container 11 and the slit 24 of the outer M21 may be replaced with simple circular or rectangular holes, and the number of slits or holes can be set to one or more, and more preferably Provide 3 to 6 pieces on the side of the vessel 11, outside 3i
It is recommended to provide one on the i21 side for the sake of removing the stored resin.

When the inner container 11 and the outer M21 are fitted and rotated in the circumferential direction and the slits 13 and 24 are aligned, the spaces of the slits 13 and 24 overlap each other,
A take-out hole A is formed in which the inside of the inner container 11 communicates with the outside air side. That is, the resin 1 stored in the inner container 11 is configured to be taken out of the container through the take-out hole A using a dental instrument or similar take-out tool 14 as shown in FIG. do. The reason why a plurality of slits 13 are provided is that the slit matching operation can be performed with a small rotation angle with the outer cover, and the above-mentioned removal tool 1
This is to allow resin 1 to reach all positions in the inner container 11 and take out the resin 1 without wasting it.

On the other hand, in the example shown in FIG.
The container is constructed so that the amount of resin 1 remaining inside the container can be detected from the outside of the container. The colored transparent plate 23 has an excellent effect of suppressing the transmission of visible light and ultraviolet rays, and there is no possibility that the resin in the small container 11 will start photopolymerizing within a short period of time. More preferably, a shielding opening/closing M24 for covering the colored transparent plate 23 is integrally attached to the outside i21, and this opening/closing M25 is opened only when checking the remaining amount of resin in the small container 11. This is desirable. The colored transparent plate is preferably a red transparent plate,
It is highly effective in blocking light rays.

Further, the colored transparent plate 23 is formed on the peripheral wall surface of the small container 11 or on the outside M.
It may be arranged on either one or both of the peripheral wall surfaces of the container 21, and by matching the slit 13 or 24 with this colored transparent plate, the remaining amount of resin in the small container 11 can be easily detected. can. Alternatively, the remaining amount of resin inside may be detected by matching the colored transparent plates 23 disposed on the small container 11 and the outer i21, respectively.Furthermore, the entire small container 11 and the outer i21 may be colored and transparent. It may be made of plastic or glass.

In addition, there are projecting edges 1 on the bottom of the inner container 11 and on the top of the outer lid 21.
2a and p22a are preferably provided so that mutual rotation can be easily performed, and the projecting edges 12a, 22a
It is desirable to apply serrations to the circumferential surface of 2a. Furthermore, in order to enable the outer lid 21 to be rotated with one hand, a fixing means such as a magnet, a suction cup, or a weight is provided on the bottom 12 of the small container 11, so that it can be fixed to a workbench on the side of the chair. It's okay.

The size of the extraction hole A is preferably large enough to allow the extraction tool 14 to pass through easily, and the width W and height H are preferably 3 to 5 mm.
