The I invention field

The present invention relates to be used for article are transported to from a place container of another place.More particularly, the present invention relates to be specially adapted to transport the container of silicon wafer, memory, hard disk, photomask, Liquid Crystal Display (LCD) and flat-panel monitor.

The explanation of II prior art

In electronics industry, adopted various containers to transport mask, telltale, disk and wafer.The fragility character of these article requires to use very the failure-free device at these article of container internal support.These article must protect, and prevent vibration and impact.These article are essential to be kept like this, makes them can scratch, the surface of friction or bump container, or leave other article in the container in.These article also must protect.Avoid shot, the influence of static and gas leakage.

The result of the recent development trend of electronics industry is mask, telltale, and the size of various wafers and dish increases.For example, though the diameter of the most of wafers that use is 200 millimeters or littler at present, occurred being the new standard wafer at center around 300 millimeters.In the future, even divide layer wafer also to be used widely possibly.Because the size of wafer, weight and face area increase, therefore must seek new technology protects these wafers, makes them exempt from damage.The generally net supporting of maintenance wafer in vogue in the container of prior art at these bigger wafers of protection, is not enough actvies when long these wafers of distance transportation particularly.Equally, the flexible supporting device that is adopted in the prior art can not provide appropriate supporting, makes the damage of wafer reduce to minimum.Common device has two supportings, a top that is bearing in container, a bottom that is bearing in container.When the top was closed, these two supportings were 180 ° of placements mutually.Therefore, reality needs a kind of pig, and it can fix the crisp article than Da Yi reliably, so that protect these article in transportation.

The invention outline

The invention provides a kind of container, it has the bottom, movable top, and two exterior ergonomics handles, a whole lock bolt can be used for bottom and top locking and three internal damping pads.Two cushion rubbers are fixed on the pig bottom, and a cushion rubber is fixed on the top.When the top was closed, three supporting line of centerss that cushion rubber had separated each other equal 120 °.This improved supporting geometric layout can provide much bigger loaded area than the design of two common cushion rubbers.

Common cushion rubber relatively is suitable for lighter and less object each other in the design of two cushion rubbers of 180 ° of placements.Yet when container is connected to each other to a side from a side, or during wigwag motion, these cushion rubbers just can not provide enough supportings for bigger wafer.By three cushion rubbers are set, and make them center on the article that will load and transport to separate equal distance, then can be in all directions, rather than only provide enough big loaded area at above-below direction.Use three cushion rubbers can also make the revolution of wafer reduce to minimum like this.This is desirable, because because the particle that the wafer revolution is produced may damage wafer.

Advantage of the present invention makes the people that are skilled in technique can be well understood to content of the present invention by the accompanying drawing of the part of book and will obtain clearer displaying to the detailed description that most preferred embodiment carries out as an illustration shown in following.

The explanation of most preferred embodiment

The external structure of Fig. 1-5 expression container 10.Container 10 is that customized design is used for transporting multiple article.Container 10 comprises bottom 20, and it has be used to pack into article and an opening that takes out article, also comprises a movable top 30, is used to cover this opening.Top 30 comprises a skirt section 32, and it is designed to work as top 30 at the off position place, and in the time of on bottom opening, skirt section 32 is overlapping with the outward flange of bottom 20.Container 10 also has a pair of handle 40 on its end face 12 and 14.People can grip container 10 in different positions.

Can adopt several method to make bottom 20 and top 30 lockings.For example, can on the skirt section 32 at top, do some holes (for example, 34 and 36). Hole 34 and 36 size and position make when top 30 during at off position, and the outshot 38 on they and the bottom 20 mates.When adopting this method, for top 30 and bottom 20 are unclamped, need catch skirt section 32, make skirt section 32 deflections, make hole 34 and 36 break away from outshot 38.Technology is the lock bolt of known some other form also, and the people that are skilled in technique can be easy to use these lock bolts to go top 30 and bottom 20 are locked together.

The inner structure of container 10 is more important.As shown in Figure 7, on the inwall of container 10, fixing three cushion rubbers 50,51 and 52.Two cushion rubbers 51 and 52 are fixed on the bottom 20, and another cushion rubber 50 is fixed on the top 30.When lid 30 when closing, three cushion rubbers are round the inside centering of container 10, and 120 ° angle separates each other.

Cushion rubber 50,51 and 52 preferably can take off from container 10.Can use the cushion rubber of different designs to come the multi-form article of clamping like this.For example, such as US Patent 5,423, the sort of cushion rubber shown in 422 can be used for clamping flat board or Liquid Crystal Display (LCD) in container 70.When utilizing container 10 to adorn silicon wafer or memory disk, can use as US Patent 5,273 the sort of cushion rubber shown in 159.These two kinds of patents all are that Empak company has, and introduce for reference here.The cushion rubber of other form can be used for clamping mask or other article.In addition, owing to cushion rubber 50,51 and 52 can take off and change, so can prolong the service life of container 10.

Fig. 8 represents in the prior art the cushion rubber 50 and 51 of this form is how to use in pairs.When as shown in Figure 8, use sort buffer pad 50 and at 51 o'clock, the sort buffer pad relatively is suitable for supporting less and lighter article.Yet the structure of two cushion rubbers is not suitable for supporting fully more greatly, heavier article (for example, diameter is 300 millimeters a silicon wafer).

By adding the 3rd cushion rubber 52, and three cushion rubbers 50,51 and 52 are placed as shown in Figure 9, can be overcome the intrinsic problem of designing institute shown in Figure 8.Absorbed by three cushion rubbers 50,51 and 52 by the power of impacting or vibration produces, therefore, article can not move.

In Fig. 9, wafer cushions 51 and 52 is fixed on the bottom 20. Cushion rubber 51 and 52 supporting line of centers 60 each other in about 120 °, and become about 60 ° to the bottom surface of wafer 53 with respect to wafer 53.When top 30 during at off position, cushion rubber 50 also contacts with wafer 53, and supporting wafer 53.Therefore, relevant with 52 with cushion rubber 50,51 supporting line of centers 60 separates each other about 120 °.

Cushion rubber 50,51 and 52 precision architecture are decided by to want in the container 10 article 53 of clamping.Yet these cushion rubbers 50,51 and 52 preferably have some common characteristic.These cushion rubbers preferably all are to make with flexible elasticity mixing (elasfomixic) material or thermoplastic plastic.Each buffering is lined with two parallel tracks 54 and 55, and they are designed to engage with the track in the container and to remain in this container middle orbit, cushion rubber 50,51 and 52 can be remained on the assigned position like this.Have a plurality of deformable parts 57 to extend between track 54 and 55, each deformable member 57 can assist to support article in many article.Each deformable member 57 generally all has two dividing plates, can form passage 58; The edge of the article 53 that support promptly is placed in the passage 58.Three cushion rubbers 50,51 and 52 passage 58 all are centerings, so cushion rubber 50,51 and 52 can work simultaneously, so that according to spaced-apart certain distance, requirement parallel to each other removes to support a plurality of article 53.Most typical is that cushion rubber 50,51 and 52 supports centering on the line of centers 60 accordingly.Although this situation is not certain essential,, making the part of each cushion rubber still is favourable in any side of its corresponding supporting line of centers 60.

Cushion rubber 50,51 and 52 is placed resulting main benefit like that shown in Fig. 7 and 9 be the supporting that the article 53 that are stored in the container 10 are provided.This structure makes the bigger article of cushion rubber 50,51 and 52 clamping sizes securely and weight (for example, diameter is 300 millimeters or bigger wafer), and can bear container 10 unexpected vibration in any direction.Structure shown in Figure 8 can be born the unexpected vibration of above-below direction.Yet when the power of unexpected vibration (shown in arrow among Fig. 8 100) effect from the side and will be with bigger, when heavier article 53 left in the container 10, the clamping meeting of article 53 became slack, or is damaged.Therefore, the structure shown in Figure 8 of the texture ratio shown in Fig. 7 and 9 is superior.

The people that are skilled in technique know that the transparent material manufacturing can be used in bottom 20 and top 30, like this even when container 10 cuts out, also can see the content in the container 10.Equally,, follow the tracks of or the communication purpose fixing bar code on the container 10, pulsed repeater or micro terminal for identification.In addition, packing seal or O shape circle can be set, to guarantee the tight seal between top and the bottom.At last, because cushion rubber 50,51 and 52 is removable, the people that technical experience is abundant can design a box, and when inserting this box in the container 10, it is same that box can play one or more cushion rubbers, and this can not depart from the present invention.
