Abstract

The utility model relates to a CD cylinder, which comprises a videotex layer and a cylinder body. The utility model is mainly formed by the method that the cylinder body and the videotex layer are connected into a whole in an injection forming mode so that the videotext layer is fixed on the surface of the cylinder body. The utility model has the fine effects on decoration, beautification and advertisement, and can improve production efficiency so as to meet the requirement of mass production.

Description

CD tube

Technical field

The utility model is relevant for a kind of CD tube, refer to especially a kind of can be in order to collect the container of most sheet discs, it has preferable decoration, beautifies and advertising results, and production efficiency is improved.

Background technology

" optical disk cartridge " reaches " CD tube " and is common container in order to the collection discs, and optical disk cartridge on the market and CD tube all styles of, kenel are extremely many.See also Fig. 1, be a kind of known CD tube, can be in order to place various discs (as CD, LD, VCD, DVD etc.), this CD tube 5 is hollow cylindrical, its bottom is opening-like, and these CD tube 5 inner accommodation spaces 51 that form can be in order to ccontaining discs.These CD tube 5 bottoms are provided with the clamping sheet 52 of a plurality of horizontal protrusions, can be in order to clamping one lower cover 6, these lower cover 6 edges stretch out and are formed with a ring flange 61, this flange 61 is provided with a plurality of and clamping sheet 52 corresponding buckling grooves 62, when this CD tube 5 is placed on this lower cover 6, can utilize this lower cover 6 to relatively rotate, above-mentioned clamping sheet 52 is connected in the corresponding buckling groove 62, this lower cover 6 is snapped together with this CD tube 5 with this CD tube 5.

But, above-mentioned known CD tube, its appearance and modeling is dull and lack variation, and visual effect is average, can't have preferable decoration, beautify and advertising results, is difficult to attract consumer's attention.Though can have the paster of literal, pattern with the bonding method setting on the CD tube surface, in the hope of reaching decoration, beautifying and advertising results, but this kind mode need be printed paster separately, and paster is pasted on laser disc tube surface when costing expenses of labour, make production efficiency to improve, be difficult to meet mass-produced demand.

As from the foregoing, above-mentioned known CD tube, on reality was used, obviously it had inconvenience and disappearance to exist, and can treat in addition improver.

So the improving of the above-mentioned disappearance of designer's thoughts of the present utility model concentrated on studies and cooperate the utilization of scientific principle, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.

Summary of the invention

Fundamental purpose of the present utility model, being to provide a kind of CD tube, and it has preferable decoration, beautifies and advertising results, and manufactures simply easily, production efficiency is improved, to meet mass-produced demand.

In order to reach above-mentioned purpose, the utility model provides a kind of CD tube, comprising: a picture and text layer, and it has picture and text; One is simplified, and itself and this picture and text layer connects as one in the mode of ejection formation, makes this picture and text layer be fixed in this drum surface.

For enabling further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Embodiment

See also Fig. 6 and Fig. 7, the utility model provides a kind of structure of laser disc tube, the manufacturing process of this CD tube such as Fig. 2 are to shown in Figure 5, the one picture and text layer 2 of moulding at first in advance, this picture and text layer 2 is made with transparent plastic material, it is laminar to be circular ring type, and printing on this picture and text layer 2 really has decoration, beautify and the picture and text 21 of advertising results, and these picture and text 21 can be literal and/or pattern.

This picture and text layer 2 utilizes a tool 3 to insert the die cavity 41 interior (as Fig. 2) of the master mold 4 of a mould, and utilize the air blowing mode that picture and text layer 2 is separated with tool 3, and make this picture and text layer 2 be attached to die cavity 41 inwalls (as Fig. 3) of master mold 4, then this tool 3 is removed, the male model 5 with this mould carries out the operation (as Fig. 4) of matched moulds with master mold 4 again.

This mould is the mould of an ejection formation, by simplified 1 (as Fig. 5) with composite molding (insert-molding) mode ejection formation one laser disc tube in this mould, this cylindrical shell 1 directly connects as one with the mode of this picture and text layer 2 with ejection formation, makes this picture and text layer 2 be fixed in this cylindrical shell 1 surface; By above-mentioned composition to form CD tube of the present utility model.

See also Fig. 6 and Fig. 7, CD tube of the present utility model includes a cylindrical shell 1 and a picture and text layer 2, and this simplified 1 connects as one in the mode of ejection formation with this picture and

text layer

2, and 21 of the picture and text on this picture and text layer 2 really have decoration, beautify and advertising results.This simplified 1 inner accommodation space 11 that forms can be in order to ccontaining discs, and this cylindrical shell 1 bottom is provided with the clamping sheet 12 of a plurality of horizontal protrusions, can be in order to clamping one lower cover (figure slightly).

Cylindrical shell of the present utility model 1 connects as one with the mode of picture and text layer 2 with the mould ejection formation, does not need the operation of pasting separately, manufactures easily simply, makes production efficiency be improved, to meet mass-produced demand.Moreover cylindrical shell 1 connects as one with the mode of picture and text layer 2 with ejection formation, and picture and text layer 2 can be very firm is attached to simplified 1 surface, difficult drop-off.

In sum, the utility model is a rare novel creation product in fact, has usability on the industry, novelty and progressive, meet novel patented claim important document fully, file an application according to Patent Law, would like to ask detailed survey and grant accurate this case patent, to ensure creator's rights and interests.

But the above only is a preferable possible embodiments of the present utility model; non-so promptly arrest limit protection domain of the present utility model; so the equivalent structure that all utilization the utility model instructionss and graphic content are done changes, and all in like manner is contained in the scope of the present utility model, gives Chen Ming together.
