[Detailed description of the invention] (Field of industrial application) The present invention relates to containers for packaging rod-shaped articles such as indwelling needles used for medical purposes, and in particular to packaging containers whose lids can be easily opened. Regarding.

(Prior art) As shown in Figure 6, this type of packaging container has a sheath body part X that houses the tip of the indwelling needle A, and a rear part of the indwelling needle A that is exposed from the rear end opening of the sheath body X. A lid body Y that accommodates the end portion and fits into the opening of the sheath body part X is known.

With such a configuration, when removing the lid B from the sheath body A and opening the lid, it is necessary to hold the sheath body A and the lid B with both hands and pull them in a direction to separate them. This is inconvenient when it is necessary to open the lid urgently, and it is particularly difficult to open the lid while holding other tools in one hand.

(Problems to be Solved) The present invention provides a packaging container that solves these inconveniences and can be opened with one hand.

(Means for Solving the Problems) For this purpose, the present invention provides a sheath body with a closed tip and an article in which a part is stored in the sheath body and the remaining part is exposed from the rear end opening of the sheath body. In a packaging container made of flexible synthetic resin, the packaging container is made of a flexible synthetic resin and includes a lid for storing and closing the sheath. A lid body is provided that covers the article exposed from the body part together with the extension part, and a connecting part is provided that integrally connects the rear end edge of the extension part and the edge of the lid body that meet when the rest of the article is covered. The lid body is formed so as to give an angle to the extension part at the connecting part, and the lid body is bent inside the extension part against the elasticity of the joint part, so that the remainder of the article is covered with the extension part. It is characterized by the provision of a locking piece that locks the lid to the opening edge of the sheath body when wrapped, and that is released by the elasticity of the connecting portion when the lid is pressed toward the extension part. .

The packaging container of the present invention is integrally formed from a flexible, that is, elastic and bendable synthetic resin such as polypropylene.

The present packaging container is composed of the above-mentioned sheath body portion and lid body. The sheath body has a length that can accommodate most of the rod-shaped articles such as the above-mentioned indwelling needle, and is a cylindrical body with a closed tip, and an opening at the rear end into which the article can be inserted. Be prepared. Further, the sheath body portion includes an extension portion that extends a part of the opening at the rear end integrally in the axial direction of the sheath body portion, and the extension portion is preferably plate-shaped. The lid has a shape that covers the article exposed from the sheath body together with the extension part, and it is preferable for the appearance to have a shape in which the sheath body is extended together with the extension part, but it is not limited to this. .

Then, when the article is wrapped, the rear end edge of the extension part and the end edge of the lid body that meet are integrally connected by the connecting part. At this time, the sheath body and the lid body are connected at the connecting part so as to give an angle to the extension part.This is because the lid body is bent inside the extension part and the article is exposed from the sheath body part. This is to provide a resilient force that causes the lid to open elastically and expose the remaining portion when the remaining portion is covered. Furthermore, the lid body includes a locking piece that locks the lid body to the rear end opening of the sheath body portion against the above-mentioned opening elastic force. This locking piece is shaped so that when the lid body is pushed toward the extension part, the engagement with the opening edge of the sheath body part is released by the elastic force of the connecting part.

(Function) With this structure, the packaging container of the present invention stores a part of the rod-shaped article in the sheath body, bends the lid body inside the extension part, and attaches the locking piece to the sheath body part. The article is packaged by locking the edge of the opening. and,
To open the lid, hold the sheath with one hand and use your thumb to push the lid toward the extension and release.The engagement of the locking piece on the lid is released by the elastic force of the connecting part, and the lid is connected. The lid opens due to the elastic force of the lid, exposing the remainder of the article that was covered by the lid.

(Example) A more detailed explanation will be given below with reference to FIGS. 1 to 3 showing an example of implementation of the present invention.

FIG. 1 shows the state before the cover body 2 is closed on the sheath body part 1.

The sheath body part 1 and the lid body 2 were injection molded using polypropylene so as to be in this state. Sheath body part 1
is a cylindrical body having a bottom at the distal end and an opening 3 at the rear end into which the indwelling needle A is inserted, and has a substantially rectangular cross section. A protrusion 4 is provided on the inside of the sheath body 1 to engage the tip of the rib b of the catheter hub a of the indwelling needle A to be housed, and to engage the rib d of the inner needle hub c.

A plate-shaped extension portion 5 in which a peripheral wall constituting one side of the substantially rectangular cross section of the sheath body portion 1 is extended in the axial direction of the sheath body portion 1.
has been established. Further, on both side edges of the extension portion 5, fitting pieces 6 that fit with the lid body 2, which will be described later, were provided.

As shown in the second figure, the lid body 2 extends the remainder of the indwelling needle A exposed from the opening 3 at the rear end of the sheath body 1 to an extension part 5.
It has a shape that envelops it together. Specifically, it has a U-shaped cross section and is composed of a side wall 7 that fits into the fitting piece 6 of the extension part 5, an upper wall 8 facing the extension part 5, and a rear wall 9.

The sheath body part 1 and the lid body 2 are connected by a connecting part 10, and the lid body 2 is formed by being bent toward the outer surface side of the extension part 5. Therefore, when covering the remainder of the indwelling needle A exposed from the sheath body part 1 with the lid body 2, the lid body 2 is bent toward the inner surface of the extension part 5 against the elastic force of the connecting part 10. . In order to bend the lid body 2 toward the inner surface of the extension part 5 and keep the indwelling needle A covered, a locking piece 11 that engages with the edge of the opening 3 of the sheath body part 1 is provided. The locking piece 11 is disengaged by the elastic force of the connecting portion 10 when the lid body 2 is pushed toward the inner surface of the extension portion 5.

With this structure, when the lid is in the closed state as shown by the imaginary line in FIG. The engagement of the stopper piece 11 is released by the elastic force of the connecting portion 10, and the lid body 2 opens as shown by the solid line in FIG.
