Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a suppository packaging container, and more particularly to a suppository packaging container in which the surface of the suppository is coated with lubricating oil when opened.

Conventional technology In order to prevent deterioration and damage of suppositories, two heat-sealable plastic plates with a suppository storage area are put together.
Recently, it has been common practice to fill a molten suppository composition into the storage area, cool it, heat-seal the area other than the storage area, and then seal and package the suppository.

Furthermore, suppositories cause considerable pain when administered, so in order to alleviate that pain, the base at the tip was made of a low-melting substance that melts more easily at body temperature than the base at the body (Japanese Patent Application Laid-Open No. 169721-1982). Publication No. 62-
192320), fill the tip of the insertion tube with lubricant,
Attempts have been made to push the suppository from the bottom and insert it into the anus, vagina, urethra, etc. while applying lubricant to the surface of the suppository (US Pat. No. 4,421,504).

However, in the above-mentioned means for alleviating pain when administering suppositories, the tip of the suppository may melt and become deformed before insertion due to summer storage conditions or clumsiness during insertion. The latter requires an expensive insertion tool and also requires complicated operations such as filling the tip of the insertion tube with lubricating oil at the time of insertion.

The object of the present invention is to provide a suppository packaging container that uses a normal type of suppository and allows the surface of the suppository to be naturally coated with lubricating oil when the suppository is taken out.

Means for Solving the Problems As a result of research aimed at solving the above problems, the inventors of the present invention have developed a suppository container made of two heat-fusible sheets joined together with a lubricant reservoir near the tip of the suppository storage section. The inventors discovered that the above-mentioned problems could be solved by creating a suppository container that can be opened from the distal end direction, and completed the present invention.

The container of the present invention is a suppository packaging container in which two heat-sealable plastic sheets are overlapped and bonded to form a suppository accommodating section 1. This suppository packaging container is provided with a non-jointed opening portion 2 at the end and a lubricating oil storage portion 3 near the tip of the suppository storage portion 1.

Hereinafter, the present invention will be explained in detail based on the drawings.

A heat-fusible plastic (eg, vinyl chloride, vinyl acetate, polyethylene, etc.) plate is provided with a recess for storing the suppository, which also serves as a mold for forming the suppository.

Rectal suppositories are bullet-shaped, urethral suppositories are pencil-shaped, and vaginal suppositories are spherical or egg-shaped, so when the two plastic plates are joined together, each suppository has the desired shape. The recess is formed as shown in FIG. The volume of the suppository accommodating portion 1 formed by this recess is generally in the range of 0.5 to 4.0 ml.

In the plastic plate, a lubricating oil (an inert, non-irritating natural or synthetic viscous liquid, such as silicone oil, olive oil, carboxyvinyl polymer viscous aqueous solution, glycerin, etc.) is applied near the tip of the suppository accommodating part 1. Provide a recess for storage. This recess forms a lubricating oil reservoir 3 when the two plastic plates mentioned above are joined together. The lubricating oil reservoir 3 may have any shape such as spherical, oval, cylindrical, or prismatic, and its volume is in the range of 0.1 to 0.01 ml.

The two plastic plates created in this way are placed in contact with each other, with the unsealed part 2 facing down, and are gradually heated and fused from the bottom until the lubricating oil reservoir 3 is formed, and the nozzle is inserted here. The lubricating oil is injected so that the lubricating oil injection ends when the reservoir 3 is formed.

Pull up the nozzle when the lubricant injection is finished. The two plastic plates are joined together by heat fusing to form a suppository accommodating section 1 in the same manner as the lubricating oil reservoir, and the molten suppository composition is filled therein.

The unsealed edges 2 of these two plastic plates, which are in the process of being joined, are left unjoined, and the remaining parts are heat-sealed and joined together.

This bonding is made to such an extent that the two plastic plates can be separated relatively easily when the unbonded opening portion 2 is pulled left and right.

In this way, the suppository packaging container of the present invention can be manufactured, but a separately manufactured suppository is placed in the suppository storage section of the heat-fusible plastic plate, lubricant oil is placed in the lubricant reservoir section 3, and Heat-fusible plastic plates may be overlapped and heat-fused in the same manner as described above.

The suppository packaging container of the present invention has an unjoined opening part 2 at one end, a suppository accommodating part 1 in the center, and the tip thereof faces in the direction where the unjoined opening part 2 is located. The structure is such that the oil reservoir 3 is located between the unjoined opening section 2 and the tip of the suppository accommodating section 1, and near the tip of the suppository accommodating section 1.

Therefore, when the unjointed opening part 2 is pulled left and right to take out the suppository, the suppository packaging container is separated into two plastic plates, and the surface of the suppository is naturally coated with lubricating oil. , the user can insert it into the patient without feeling any pain.

In addition, the suppository packaging container of the present invention can be used for ordinary suppositories if it is filled with only lubricating oil and fused, and is molded without filling the suppository composition with the suppository accommodating part 1 left unfused at the bottom. It can be applied to ordinary suppository filling machines as well as packaging containers.

Effects of the invention According to the invention, it has become possible to provide a suppository packaging container in which the surface of the suppository is naturally coated with lubricating oil when opened.
