Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a photopolymerizable composite resin filler (hereinafter referred to as "
It is abbreviated as "photopolymerizable resin". This invention relates to a storage container for replenishing photopolymerizable resin that can be injected as needed into syringe-type containers, which are often used as storage and filling containers.

<Prior art> In recent years, in the field of dental composite resin fillers, instead of the conventional two-paste type chemical polymerization type,
1. Demand for paste-type photopolymerizable resins is rapidly increasing.Since such photopolymerizable resins start a reaction when exposed to light, complete light shielding is required except when in use.Specifically, stability over time and Syringe type containers with excellent light blocking properties are often used as storage and filling containers. However, in the case of syringe-type containers, due to their structure, the storage capacity is only about 1/4 to 1/2 of that of jar-type containers. Accidents that require replacement are likely to occur, and in that case, it will cause variations between lofts, resulting in poor finished quality.

In addition, since the syringe type container is disposable, the amount of consumption of the container is enormous, making it extremely uneconomical.

<Problems to be Solved by the Invention> The present inventors have completed the present invention as a result of intensive research in view of the above-mentioned problems, and its purpose is to solve the problems that were conventionally disposable. To provide a storage container that enables the reuse of a syringe type container, stores a replenishment photopolymerizable resin in a stable state over time, and injects the replenishment photopolymerizable resin into the syringe type container as appropriate.

<Means for Solving the Problems> The above-mentioned object is to provide a storage member with a storage capacity of 5cj or more of photopolymerizable resin, and to provide a storage member with an opening at one end and a closing means at the other end. The opening is achieved by a storage container that is removably engaged with the cylinder of the syringe type container.

The present invention presupposes the existence of a syringe-type container consisting of a cylinder and a piston. The container according to the present invention is composed of an opening 10, a closing means 20, and a storage member 30, and the storage member 30 has a substantially cylindrical shape, and the opening 10 is provided at one end of the storage member 30, and the closing means is provided at the other end. 20 are arranged.

A locking means 11 similar to that attached to a piston constituting a syringe type container is attached to the mouth part 10, so that the cylinder and the mouth part can be freely connected. Therefore, since the storage container and the syringe-type container communicate only through the mouth, when in use, the cylinder and piston of the syringe-type container are separated, the mouth 10 is engaged in place of the piston, and then the closing means is 20 etc., inject the replenishment photopolymerizable resin in the storage container into the cylinder.

Various types of closure means 20 can be considered, but if necessary, the photopolymerizable resin for replenishment in the storage container may be used as the closure means 20.
It is preferable that the closing means 20 be concentrated near the opening 10. Therefore, the closing means 20 needs to have the function of not only separating the inside and outside of the storage container, but also adjusting the positional relationship of the closing means 20 with respect to the opening 10.

The storage member 30 stores at least 54 or more photopolymerizable resins. Although there is no particular limitation on the shape, a substantially cylindrical body or the like that allows stored items to move smoothly to the opening 10 is preferable.

The aforementioned mouth portion 10. The materials constituting the closing means 20 and the storage member 30 need to satisfy the conditions described below.

In other words, in terms of maintaining the quality of the stored items, materials with high oxygen permeability and excellent light-shielding properties are preferred; specifically, plastics that do not require the addition of plasticizers, such as polypropylene, polyethylene, and polyurethane. 9, a rubber elastic body, a laminate, etc. are suitable. Regarding the color tone, an opaque material is preferable from the viewpoint of light-shielding properties, and for example, when using the above-mentioned plastic or rubber elastic material, black is safe. Furthermore, the shape of the container naturally changes depending on the material selected, and in the case of a highly flexible material, a tube body like the one shown in FIGS. 1 and 2 is preferable as embodiment a 1. On the other hand, when a relatively hard material is selected, a storage container such as the syringe type container shown in FIGS. 3 and 4 is preferable as the second embodiment.

The amount of photopolymerizable resin stored in the storage container is 30
By changing the shape of the storage container, you can adjust it as you wish.

For example, in the case of Embodiment 1, it is sufficient to change the diameter of the tube body that is the storage member, and in the case of Embodiment 2, it is sufficient to adjust the diameter of the large cylinder that is the storage member. From the viewpoint of ease of handling, it is preferable to have a storage capacity of about 20c4.

Embodiment 1 shown in FIGS. 1 and 2 and Embodiment 2 shown in FIGS. 3 and 4 will be described below.

In embodiment 1, the storage member 30 is a tube body,
A mouth portion 10 is provided at one end and a closing means 20 is provided at the other end.
The mouth part 10 is a cylindrical body having a smaller diameter than the storage member 30, and a thread is carved as a fastening means 11 on the outer peripheral surface of the mouth part. Since the thread is a means of engagement with the cylinder constituting the syringe type container, it is similar to that applied to the piston. Furthermore, for the mouth part, a relatively hard material with no flexibility is preferable for its function of engaging the cylinder. The closing means 20 can be obtained by processing a tube body using a general method such as heat fusion. The storage member 30 is preferably made of a flexible material such as laminate. When it becomes necessary to replenish the photopolymerizable resin in the syringe type container, after removing the piston from the cylinder, screw the mouth part 10 with the cylinder instead of the piston, and press the storage container to refill. Transfer the photopolymerizable resin into a cylinder. When the required amount of injection is completed, the cylinder and piston are engaged instead of the mouth part 10. Further, when moving the stored items to the vicinity of the opening as necessary, the closing means may be sequentially folded toward the opening to narrow the distance between the opening 10 and the closing means 20.

Embodiment 2 is based on a conventional syringe type container, and consists of a spout 10, a large cylinder serving as a storage member 20, and a push rod serving as a closing means 30. The opening lO is made into a cylindrical body having a diameter smaller than that of the storage member 30, as in the first embodiment, and a thread is carved into the outer peripheral surface of the opening as a fastening means 11. Since the thread is a means of engagement with the cylinder constituting the syringe type container, it is similar to that applied to the piston.

The closing means 20 is a pushing rod, and one of its functions is to concentrate the stored items in the large cylinder, which is the storage member 30, near the mouth, and is made up of a disk 21 and a support rod 22 that supports the disk. Become. The disc 21 has a shape that allows it to slide on the inner peripheral surface of the large cylinder. And the support rod 22 has an A thread 2.
3, and the A thread 23 is screwed together with a B thread, which will be described later. This is the storage member 30. Also, the material is mouth part 10. Both the storage member 20 and the closing means 30 are preferably relatively hard.

Next, to explain the case where it is necessary to replenish the photopolymerizable resin in a syringe type container, after removing the piston from the cylinder, screwing the mouth part 10 with the cylinder instead of the piston, and then By moving the disk 22 toward the mouth within the large cylinder, the disc 21 is brought close to the mouth 10 and the stored contents are poured out. As a result, the stored replenishment photopolymerizable resin is transferred to a syringe type container. When the injection of the required amount is completed, the cylinder and piston are reattached in place of the mouth portion 10, and the replenishment of the photopolymerizable resin is completed.

<Effects of the Invention> Since the storage container according to the present invention uses a material with excellent oxygen permeability and light shielding properties, the storage container has excellent stability over time of stored items. Furthermore, since a sufficient amount of photopolymerizable resin can be stored in the storage container to refill the syringe type container, the stored items can be transferred to the syringe type container as needed and the syringe type container can be used repeatedly. This also makes it possible to stop the wasteful use of resources. In addition, if it becomes possible to use syringe-type containers repeatedly, even syringe-type containers with relatively high prices will be able to attract consumers. It is thought that the container was obtained.
