Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to improvements in CD containers. The cover-equipped CD container of the present invention can be attached with a paper surface showing the title and other items over the entire front and back of the container. In a recommended mode, a small pamphlet can be stored together with the CD, and when the CD is stored in the container, it should be securely fixed and held, and vibration during transportation should be ensured. Thus, the CD does not fall out of a predetermined position in the container. Here, "CD" is a generic term for optical information media such as CDs, MDs, and DVDs.

[0002]

[Prior art]

 The most common container for exhibiting and selling CDs is of the type that holds one or more CDs in an acrylic case. To fix a CD in an acrylic case, as is well known, a low cylindrical projection is divided into a plurality of parts by radial slits, and each piece is provided with a locking piece with spring properties. The center hole of the CD is fitted. Since the depth of the case is equivalent to one CD, the CD placed in the acrylic case does not fall off the predetermined position.

[0003] The acrylic case currently used has a shape established when the CD is mainly a music CD, and therefore, the only thing that can be accommodated other than the CD is a single label or at most. Limited to several small pamphlets. On the other hand, as the number of CDs recorded with computer software has increased, there has been a desire to handle CDs together with pamphlets or leaflets such as manuals, instructions, and guarantees. Conventional acrylic cases have not been able to adequately answer this request.

In recent years, attempts have been made to use a slightly larger and thicker container instead of the conventional acrylic case. The CD container is a shallow box made integrally by injection molding of polypropylene, and the fixing of the CD is performed by the same spring locking piece as that performed in the acrylic case.

[0005] A delicate balance is required for the strength of fitting between the spring locking piece and the CD center hole. If the spring is strong, the CD can be fixed firmly, but it will be difficult to open the container and remove the CD. On the other hand, if the spring is weak enough to easily take out the CD, the CD will easily fall off with some vibration. It would be good if the enclosed pamphlet had an appropriate thickness and suppressed CD, but this is not always possible. As such, the use of these new CD containers is limited.

[0006] In order to deal with such a problem, the inventor of the present invention has proposed a CD container capable of accommodating a CD and a pamphlet and the like related to the CD together with a brochure. Regardless of whether or not to do so, and regardless of whether the pamphlets are thick or thin (of course, the thicker ones are naturally limited), the stored CDs may fall off the spring engaging pieces during transportation and handling. We have developed a CD container that does not have this and have already disclosed it (Utility Model Registration No. 3074118).

As shown in FIG. 1, the CD container has a back plate (1) and a shallow box-shaped front cover (2) and a back cover (3) connected to the back plate so as to be openable and closable through the back plate (1). Is a flat box-shaped CD container having the following components as a minimum component, and the back plate (1) is connected to the front cover (2) and the back cover (3) by a hinge connection (4). Nearly the center of the edges (21, 31) rising from the left and right sides of the front cover (2) and the back cover (3) forms retreating portions (22, 32) for opening the container. A protruding piece (6A) is provided on one of the front cover and the back cover, and a groove (6B) corresponding to the protruding piece is provided on the other, so that the container can be kept closed by fitting the two, and the back cover (3) A spring engaging piece (5) for fixing the CD by fitting it into the center hole of the accommodated CD is provided substantially at the center of the CD. The retraction portion (22) of the front cover (2) is provided with a front cover CD restraint (23) extending toward the inside of the container, and has an L-shaped pan fret stop (24) inside the front cover on both sides thereof. ), A rib (11) extending toward the inside of the container is erected substantially on the center line of the back plate (1), and a back plate CD restrainer (12) is protruded almost at the center of the rib, thereby closing the container. Sometimes, as shown in FIG. 2, the CD cover (23) and the back plate (12) cooperate with each other to prevent the CD from falling off from the spring engaging piece. It is.

Although the above-mentioned CD container has an excellent function of securely holding a CD, it is not suitable for attaching a sheet of paper on which a label or a description item is described to the surface of the container. It is not necessary to attach an adhesive or pressure-sensitive adhesive to the back plate (1), front cover (2) or back cover (3). This is the work, and the attached paper is not protected, so there is a risk of fouling and wear.

[0009]

[Problems to be solved by the invention]

 An object of the present invention is to provide a CD container having a size and a structure capable of accommodating a pamphlet together with or without a mechanism for ensuring that the CD is prevented from dropping from a spring engaging piece. Even so, it is an object of the present invention to provide a CD container with a cover that can easily attach a sheet of paper on which a label or an explanation is written to the surface of the container, and that the sheet is protected against contamination and abrasion. .

[0010]

[Means for Solving the Problems]

 As shown in FIGS. 3 to 5, the cover-equipped CD container of the present invention comprises a back plate (1), a front cover (2) having a shallow box shape, and a back cover (2) connected through the back plate (1). A flat box-shaped CD container having a lid (3) as a minimum component, and the back plate (1) is connected to the front lid (2) and the back lid (3) by a hinge connection (4). The container can be kept closed by fitting the front cover (2) and the back cover (3), and the center of the back cover (3) is fitted into the center hole of the CD to be stored. In a CD container having a main body provided with a spring retaining piece (5) for fixing a CD, grooves (7A) are formed along the edges of the container open end on the surface of the front cover (2) and the back cover (3). , 7B), and ridges (8A, 8B) provided inside them, and the front cover (2) and the back cover (3) In the above, the upper and lower edges are edges (25, 35) slightly protruding from the surface, the width is almost equal to the length of the CD container, and the length is slightly longer than the above-mentioned groove interval when the CD container is unfolded. A long, transparent plastic cover film (9) is fixed by gluing its ends to the bottom of the groove.

[0011]

[Embodiment of the invention]

 The structure of the CD container that ensures the fixation of the CD, which was proposed earlier, is a recommended mode for implementing the present invention. That is, as shown in FIG. 1 and FIG. 2, the substantially central portions of the edges (21, 31) rising from the left and right sides on the back side of the front cover (2) and the back cover (3) are retracted to open the container. (22, 32) are formed, and on both sides thereof, a protruding piece (6A) is provided on one of the front cover and the back cover, and a groove (6B) corresponding to them is provided on the other. To keep the container closed, and the retraction portion (22) of the front cover (2) is provided with a front cover CD holder (23) extending toward the inside of the container, and the front cover is provided on both sides thereof. An L-shaped pamphlet stopper (24) is provided in the inside of the container, a rib (11) extending toward the inside of the container is set up almost on the center line of the back plate (1), and a back plate CD holding device (12) is set almost in the center. ) To protrude, and when the container is closed, D suppressed (23) and the back plate CD depressive example (12) are jointly a structure of a CD container that is configured to prevent falling off from the spring engaging piece of CD.

In addition to the above aspect, in order to facilitate the fixing of the CD, the back cover (3) has a diameter slightly larger than the outer circumference of the CD, concentric with the CD spring locking piece (5). An embodiment in which a circular ridge (33) is provided so as to limit the periphery of the CD is also preferable as an embodiment of the present invention. This circular ridge (33) is preferably formed by recessing a part of the back cover, and does not increase the thickness.

The material for manufacturing the CD container with the cover of the present invention can be arbitrarily selected, but first, for the container body, polypropylene, which is known as a material whose hinge connection exhibits durability, is the most influential. Since polypropylene is a plastic with excellent workability, the container body is manufactured by injection molding of polypropylene, and the connection between the back plate (1), the front cover (2) and the back cover (3) is all hinged. (4) is better. The transparent plastic cover film (9) to be applied on the outside is also optimally made of a tough material, polypropylene. As a means for fixing both ends of the plastic film to the grooves (7A, 7B) of the container body, heat sealing is appropriate. If the container body and the film are made of the same polypropylene, the bonding by heat sealing can be performed firmly.

As can be easily understood from the above description, the attachment of the paper surface on which the labels and explanations are described is made by expanding the cover-equipped CD container as shown in FIG. 3 and FIG. This is done by inserting between the cover film. In the state where the CD container is opened, there is a sufficient gap between the container body and the cover film as shown in FIG. 4, so that the insertion is easy, and the paper surface is the above-mentioned ridge (8A, 8B). ) And a slightly concave portion formed by the upper and lower protruding edges (25, 35).

[0015]

[Effect of the invention]

 The CD container with the cover of the present invention can easily attach the paper surface on which the label and the description are described to the entire surface of the container, and does not require the use of an adhesive or an adhesive. When the container is closed, the cover film is pulled and comes into close contact with the container body, so the paper is fixed between them. Even when the container is reopened, the cover film does not fall off because the paper is sandwiched by the portions where both ends of the cover film are fixed to the container body, while it is possible to take it out.

In the preferred embodiment of the invention, that is, in the case where the container is provided with a CD hold-down, the CD is firmly fixed and transported because it prevents possible axial movement of the CD on the spring retaining piece.・ The benefit is that there is no risk of the CD falling off due to vibration during handling.
