Description

The present invention relates to an improvement of a CD container, and a CD that is to be packaged is securely fixed and protected when accommodated in the container, and a container that can be easily removed when the container is opened. provide. This container can accommodate two CDs. Here, the term “CD” represents one having the same or similar shape as a CD, including DVD and MD.

Containers used for transporting and storing optical information media such as CDs, MDs, and DVDs contain one or more discs as they are or in an acrylic case. In general, a disc that contains a disc is not sufficiently fixed in the disc position in the container, and depending on the handling of the vessel, the disc may move inside and hit the vessel, or the discs may come into contact with each other, resulting in damage. I may receive it. What is housed in an acrylic case is relatively safe from the viewpoint of disk protection, but if the case itself is not fixed yet, it will still move inside the container and the case will open. The risk of damaging the disc is not lost.

However, if the disc and the acrylic case are firmly fixed inside the container, this time is troublesome when the container is opened and the package is taken out. Therefore, while the CD is being stored, it is securely fixed and held, and even if the container is moved violently, the package is not shaken or moved inside. When removing the CD by opening the CD, there has been a demand for a packaging container that can be easily removed after the fixation has been released.

As an effort to meet such a demand, in a conventional acrylic case type storage cassette, a holding element for holding a CD is provided from three sides, and the one near the opening / closing axis is used as an elastic holding element, and the lid is closed when the lid is closed. Has been proposed in which the locking element engages with the elastic holding element to restrict its movement (Patent Document 1). Similarly, a holding device having three claws on the circumference and cooperating with a boss portion to be inserted into a hole in the center of the CD has been disclosed (Patent Document 2), but the CD itself is exposed. So it does not work as a container.

The inventor is a packaging container in which both a shallow box-shaped front plate and a back plate are connected to an intermediate plate by hinge connection, and a hook-shaped latch that holds the end of the CD in a portion near the hinge A package configured such that when a piece is provided and the container is closed, a protrusion provided on the intermediate plate pushes the locking piece from behind to deform it, thereby ensuring the fixation of the CD and releasing the fixation when opened. A container was developed with a joint inventor and has already been proposed (Patent Document 3).

All of the known CD containers are intended to accommodate one CD, and cannot satisfy the demand for improving efficiency by accommodating two CDs in one container. Further, in many cases, it is desirable to enclose a pamphlet such as a manual related to the contained CD in the CD container, but the conventional CD container does not consider such a demand.

The object of the present invention is to sufficiently hold the original function of the packaging container such that the CD can be securely held while it is accommodated, while the CD can be easily removed when the container is opened. It is an object of the present invention to provide a CD container having a structure that can accommodate two CDs in one container and is convenient for enclosing a pamphlet.

As shown in FIG. 1 and FIG. 2, the CD container of the present invention that achieves the above-described object includes a front cover (2A) and a back cover (2B) that are openably and closably connected via a back plate (1). ), Which is basically a CD container for storing two CDs, wherein the back plate, the front cover and the back cover are connected by hinges, and the front cover and the back cover are each provided with side walls (21A in three directions). , 22A, 23A and 21B, 22B, 23B), and the central part of the end side walls (22A and 22B) forms a recess (24A and 24B) that provides a handle for opening the closed container; A CD fixing boss (3A and 3B) having a plurality of radial slits for elastically fitting with the center hole of the CD to fix the CD is provided at the center of the front cover and the back cover. Circumferential intermittent ridges along the outer circumference ( 5A and 25B) are provided except for the portion in contact with the back plate, and a locking piece having a hook (51) for locking the end of the CD housed in the front cover near the free end of the front cover (5) is elastically raised, a stop piece (6) is raised near the free end of the back cover, and a central protrusion that receives the ends of the two CDs when the container is closed at the center of the back plate. (11) is protruded, and on the free end side of the back cover, an L-shaped pamphlet holder (71) and a pamphlet stand (for holding the pamphlet on a CD stored in the back cover) 72) is provided on both sides, and a pair of engaging protrusions (81) and receiving parts (82) are provided at positions corresponding to the front cover and back cover, respectively, and when the container is closed, The closed state is maintained by the engagement of the protruding part and the receiving part, and the stop piece raised from the back cover stands from the front cover. Entered behind the locking piece, a CD container configured so as to prevent deformation in the behind.

When the CD container of the present invention accommodates a CD on the side of the front cover (2A), the elastic locking piece (5) is provided while the center hole of the CD is fitted into the CD fixing boss (3A) of the front cover. After falling backwards to accept the end of the CD and fitting it back, it will return to its original position and the heel (51) holds the end down to prevent movement and dropout. The periphery of the CD is regulated and protected by the ridge (4A). The CD housed on the back cover (2B) side is fitted into the CD fixing boss (3B) of the back cover and is only regulated and protected by the ridge (4B). When the pamphlet holder (71) and pamphlet stand (72) shown in detail in FIG. 3 are sandwiched and stored, the pamphlet prevents the CD from dropping out. When the container is closed, the set of the protrusion (81) of the front cover shown in FIG. 5 and the receiving part (82) of the back cover shown in FIG. 5 are engaged as shown in FIG. Kept. At the same time, the back cover stop piece (6) enters behind the front cover engagement piece (5), preventing the deformation of the engagement piece falling backward. In the closed state, the central projection (11) of the back plate (1) is located close to the end of the two CDs near the back plate and prevents the CD from being displaced in that direction.

When the CD container is opened and the CD is taken out, if the lid is opened by the handle provided by the receding portions (24A and 24B) provided on the side walls (22A and 22B) of the front cover and the back cover, the restriction by the central protrusion is eliminated. Therefore, it can be separated from the CD fixing boss (3A and 3B) with the periphery of the CD in a portion where there is no intermittent protrusion (4A and 4B). In this way, the CD can be reliably held in the closed state, while the CD can be easily taken out in the open state, and a CD container that can accommodate two CDs is realized.

The material for producing the CD container of the present invention can be arbitrarily selected, but polypropylene is the most promising material, which is known as a material having a durable hinge connection. Since polypropylene is a plastic with excellent processability, it is advantageous to produce the entire CD container by injection molding of polypropylene.

In this type of CD container, it is desirable to have a cover for the purpose of displaying or decorating the contents. The cover can be held by sticking across the cover-back plate-back cover, which is the main body of the container, but as will be easily understood, the cover is immediately damaged by opening and closing the container. It is preferable to exist independently of the main body of the container. As shown in FIGS. 7 and 8, on the outside of the front lid (2A) and the back lid (2B), three edges other than the edge connected to the back plate are projected to protrude the ridges (25A and 25B). It is recommended that a cover cover (9) made of a transparent plastic film is provided on the concave surface formed on the inner side thereof by fusing only at both ends by fusing parts (9A and 9B).
