Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to inserts, and particularly to inserts for integral heat spreader (IHS) packaging.

2. Description of the Prior Art

In one kind of conventional IHS packaging, a plurality of IHS blocks is stacked inside a container. There are no fixing devices between the IHS blocks. Accordingly, during transportation, the IHS blocks are prone to move at random and strike each other. This often results in damage to some of the IHS blocks.

In another kind of conventional packaging, a plurality of IHS blocks is stacked in a hollow tube. A plurality of such tubes is stacked inside a container. During transportation, the tubes are prone to move at random and strike each other. The IHS blocks inside the tubes are thus liable to sustain shock and damage.

A new means for packaging IHS blocks which overcomes the above-mentioned problems is desired.

SUMMARY OF THE INVENTION

An object of the present invention is to provide an insert for IHS packaging which prevents or minimizes the risk of damage to IHS blocks during transportation.

In order to achieve the above object, an insert for integral heat spreader (IHS) packaging in accordance with a preferred embodiment of the present invention comprises a handle and a locking portion extending from one end of the handle. The locking portion comprises a pair of resilient arms. The resilient arms comprise a pair of guides formed at free ends thereof, and a plurality of teeth formed along outer edges thereof. In use, IHS blocks are stacked inside a receiving box. A pair of inserts is inserted into a pair of locking slots defined in the receiving box near opposite ends thereof. A plurality of locking edges of the receiving box at the locking slots is received between corresponding teeth of the inserts. A plurality of such duly assembled receiving boxes is retained in a plurality of parallel channels defined in a container, with exposed portions of the inserts being received in a plurality of locking recesses defined in the container. Thus the IHS blocks are protected from unwanted movement and damage.

Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will now be made to the drawings to describe the present invention in detail. [0015]
Referring to FIGS. 1 and 2, an [0016] insert 1 for integral heat spreader (IHS) packaging in accordance with a preferred embodiment of the present invention comprises a handle 2 and a locking portion 3.
The [0017] handle 2 has a generally bell-shaped profile. A circular through hole 22 is defined in a middle portion of the handle 2. When the insert 1 is engaged in or disengaged from a receiving box 4, a user's hand or a tool (not shown) can hold the insert 1 at the hole 22 to facilitate the operation of engaging or disengaging. The locking portion 3 extends from one end of the handle 2, and comprises a pair of resilient arms 31. The resilient arms 31 are parallel to each other, and a U-shaped gap 32 is defined therebetween. Each resilient arm 31 forms a multiplicity of evenly-spaced teeth 312 along an outer edge thereof. A pair of slanted guides 313 is formed at free ends of the resilient arms 31 respectively.
Referring also to FIG. 3, the [0018] receiving box 4 is long and hollow. Both ends of the receiving box 4 are open. The receiving box 4 defines a pair of vertical locking slots 41 near opposite ends thereof respectively. A plurality of locking edges 410 is formed in top and bottom walls of the receiving box 4 at the locking slots 41.
In use of each [0019] insert 1, the guides 313 of the resilient arms 31 guide the resilient arms 31 into the corresponding locking slot 41 of the receiving box 4. The resilient arms 31 elastically deform toward each other. The locking portion 3 of the insert 1 is fully inserted into the locking slot 41 until the guides 313 protrude out from the bottom wall of the receiving box 4. Thus the locking edges 410 of the receiving box 4 are snappingly received between corresponding teeth 312 of the resilient arms 31. Accordingly, the insert 1 is securely locked in the receiving box 4. This ensures that IHS blocks 5 can be snugly received in a stack in the receiving box 4, thereby minimizing the risk of damage to the IHS blocks 5.
To disengage each [0020] insert 1 from the receiving box 4, the resilient arms 31 are deflected toward each other. A user's hand or a tool (not shown) grips the handle 2 of the insert 1. The insert 1 can then be conveniently pulled out from the receiving box 4.
Referring to FIG. 4, a [0021] container 6 defines a plurality of parallel and slightly staggered channels 62, and a pair of locking recesses 64 at opposite ends respectively of each of the channels 62. The locking recesses 64 are in communication with the respective channels 62. Each receiving box 4 is filled with a stack of IHS blocks 5. The inserts 1 are inserted into the locking slots 41 of the receiving box 4. Then a plurality of such duly assembled receiving boxes 4 is respectively received in the channels 62 of the container 6, with exposed portions of the inserts 1 being received in the corresponding locking recesses 64 of the container 6. Thus the receiving boxes 4 are securely retained in the container 6, and the IHS blocks 5 are protected from damage.
Referring to FIG. 5, an [0022] insert 1′ in accordance with an alternative embodiment of the present invention has a structure similar to that of the insert 1 of the preferred embodiment. The insert 1′ comprises a handle 2′ and a locking portion 3′. The locking portion 3′ extends from one end of the handle 2′, and defines an elongated cutout 32′ in a middle portion thereof. The locking portion 3′ forms a multiplicity of evenly-spaced teeth 312′ along opposite outer edges thereof. A tapered guide 313′ is formed at a free end of the locking portion 3′. The insert 1′ can perform substantially the same function as described above in relation to the insert 1 of the preferred embodiment.
While preferred embodiments in accordance with the present invention have been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present invention are considered within the scope of the present invention as defined in the appended claims.
