Examples

When some fragile products are transported, certain foam or pearl wool is often coated at the edges and corners of the products to avoid damage to the products during transportation.

In order to enable a single container to carry more thin fragile products, it is common to place the thin fragile products vertically when transporting some large thin fragile products such as shower glass, bathroom mirrors, tiles, etc. Because of the large dead weight of the thin fragile products or the ceramic tiles, certain shaking or vibration is inevitably generated in the transportation process. When the foam is used for cushioning the thin fragile product, as the foam at the bottom of the thin fragile product is always abutted by the thin edge of the thin fragile product, the thin fragile product has larger mass, the thickness of the foam is continuously thinned under the heavy pressure of the thin fragile product, after the foam is subjected to the heavy pressure for a period of time, the foam which is 15mm thick originally can be compressed to 2mm, and the foam does not have cushioning capability at this time, if the follow-up thin fragile product shakes or vibrates again, the bottom of the thin fragile product directly collides with the inner wall of a container for loading the thin fragile product, and the thin fragile product can be damaged in the collision process.

Accordingly, in order to avoid damage to the slim fragile products during transportation, the present utility model discloses a paper packaging assembly made of pulp fibers, which has a higher strength than the foam. And the paper package assembly clamps the thin fragile product by the upper case 10 and the lower case 20 and supports the thin fragile product by the first protrusions 12 and the third protrusions 22 so that both sides of the thin fragile product can be well supported during transportation. The four thin edges of the thin fragile product are supported by the bumps 23, so that the thin edges of the thin fragile product are always well supported, and the thin fragile product is prevented from directly colliding with the container.

Referring specifically to fig. 1-4, the paper wrapper assembly includes an upper housing 10 and a lower housing 20. The upper case 10 includes a first plate 11 and a first protrusion 12 in a bar shape, the first protrusion 12 is provided in plurality, and the first protrusion 12 is fixedly connected to an upper surface of the first plate 11 in parallel, the lower case 20 includes a second plate 21 and a third protrusion 22 in a bar shape, the third protrusion 22 is similarly provided in plurality, and the third protrusion 22 is fixedly connected to an upper surface of the second plate 21 in parallel. The upper surface of the third protrusion 22 is provided with a protrusion 23, the lower surface of the first protrusion 12 is provided with a groove 13, the groove 13 is used for installing the protrusion 23, and the height of the protrusion 23 is greater than the depth of the groove 13, so that a gap 30 can be reserved between the upper case 10 and the lower case 20, and the gap 30 is used for placing products C such as thin fragile products and tiles.

In an embodiment of the present utility model, in order to make the upper and lower cases 10 and 20 have a good clamping effect on the product C, the height difference between the projection 23 and the recess 13 is generally set to match the thickness of the thin fragile product or tile.

Further, the protruding block 23 is disposed at an end of the third protruding block 22, that is, the protruding block 23 is disposed at an edge of the first plate 11, and one protruding block 23 is disposed at an end of each of the elongated third protruding blocks 22, and one groove 13 is disposed at an end of each of the elongated first protruding blocks 12. After the bump 23 is disposed at the edge of the first plate 11, the upper housing 10 and the lower housing 20 can have a larger area for clamping the product C, so that the pressure applied to the packaging assembly by the product C is smaller, and deformation of the packaging assembly is avoided.

Preferably, in an embodiment of the present utility model, the upper case 10 further includes a reinforcing block 14, the reinforcing block 14 is fixedly connected to an edge position of the lower surface of the first plate 11, and the reinforcing block 14 is used for abutting against the upper surface of the second plate 21. And the reinforcing block 14 is adjacent to the recess 13, avoiding the reinforcing block 14 interfering with the normal placement of the product C.

Preferably, in an embodiment of the present utility model, the reinforcing block 14 may be provided in plurality, and the reinforcing block 14 is provided at only one side position of the first plate body 11.

Preferably, in an embodiment of the present utility model, the reinforcing blocks 14 are provided in one, and the reinforcing blocks 14 extend along the edge of the first plate body 11, so that the mold setting of the upper case 10 is simpler.

In one embodiment of the present utility model, the upper and lower housings 10 and 20 may be solid housings.

In one embodiment of the present utility model, to enable faster dry forming of the pulp fiber made package assembly, the upper housing 10 and the lower housing 20 are each provided as thin walled housings of equal wall thickness. In actual production, the thicknesses of the upper case 10 and the lower case 20 are generally controlled to about 3mm, so that the upper case 10 and the lower case 20 can be dried easily while being sufficiently strong.

Specifically, the first projection 12, the third projection 22, the projection 23, and the reinforcing block 14 are all thin-walled housings.

Referring to fig. 1 and 3, the upper case 10 further includes a first reinforcing rib 15, the first reinforcing rib 15 is fixedly connected to the upper plate, and the first reinforcing rib 15 surrounds the upper surface edge of the first plate 11. After the first reinforcing ribs 15 are provided, the deformation resistance of the whole first plate 11 is enhanced, so that the first plate 11 can bear larger force applied by the product C, and the upper shell 10 is convenient to demold.

Of course, the lower case 20 likewise includes a second reinforcing rib 24, the second reinforcing rib 24 is fixedly connected to the second plate 21, and the second reinforcing rib 24 surrounds the upper surface edge of the second plate 21. After the second reinforcing ribs 24 are provided, the deformation resistance of the whole first plate 11 is enhanced, so that the first plate 11 can bear larger force applied by the product C, and the lower housing 20 is convenient to demold.

Further, when the product C such as a thin fragile product is packaged by a paper packaging unit, the product C is generally laid on a bottom surface or a table, and the lower housing 20 needs to withstand a large pressure. Referring to fig. 3 and 5, the second reinforcing rib 24 extends toward the top surface of the third protrusion 22, and the top surface of the second reinforcing rib 24 is close to the top surface of the third protrusion 22. When the product C is placed between the upper and lower cases 10 and 20, the hollow first protrusions 12 are compressively deformed and provide a supporting force to the product C when the product C presses the upper case 10. When the product C presses the lower shell 20, the hollow second protrusion 16 is compressively deformed and provides a supporting force for the product C, and the second reinforcing rib 24 can provide a supporting force for the product C at the same time because the second reinforcing rib 24 is close to the second protrusion 16, or the second reinforcing rib 24 provides a supporting force for the product C after the second protrusion 16 is deformed to a certain extent, so that the stability of the lower shell 20 is ensured.

As shown in fig. 3, the upper case 10 further includes a plurality of second protrusions 16, the second protrusions 16 are disposed at intervals in the gaps of the adjacent first protrusions 12, and both ends of the second protrusions 16 are fixedly connected with the adjacent two first protrusions 12, respectively. And further, the structure between the adjacent first protrusions 12 is more stable, and the toppling state between the adjacent first protrusions 12 does not occur.

The lower case 20 further includes a plurality of fourth protrusions 25, the fourth protrusions 25 being disposed at intervals in gaps of adjacent ones of the third protrusions 22, and both ends of the fourth protrusions 25 being fixedly connected with the adjacent two third protrusions 22, respectively. Further, the structure between the adjacent third protrusions 22 is more stable, and the state of tilting between the adjacent fourth protrusions 25 does not occur.

Of course, the second protrusions 16 and the fourth protrusions 25 are also provided in a hollow, and the second protrusions 16 and the fourth protrusions 25 provided in a hollow can be dried more quickly.

Meanwhile, in an embodiment of the present utility model, as shown in fig. 5, the length of the top of the first protrusion 12 is smaller than that of the bottom, so that the two ends of the first protrusion 12 are inclined, thereby facilitating the demolding of the upper housing 10.

Similarly, in an embodiment of the present utility model, referring to fig. 3 and 5, the length of the top portion of the third protrusion 22 is smaller than that of the bottom portion, so that the two ends of the third protrusion 22 are inclined, thereby facilitating the demolding of the lower housing 20.

As described above, when the bump 23 is provided only at one end of the third protrusion 22, as shown in fig. 3, no bump 23 is provided at the other three sides of the second plate 21. A paper packaging assembly consisting of an upper housing 10 and a lower housing 20 of this type is typically used to hold the sides of a product C, such as a thin fragile product.

The utility model also discloses another paper packaging assembly shown in fig. 6-9, wherein the strip-shaped first bulge 12 and the strip-shaped third bulge 22 are arranged in a bending way, and two ends of the strip-shaped third bulge 22 are arranged on two adjacent sides of the second plate body 21.

Comparing fig. 1-4 with fig. 6-9, wherein the first protrusion 12 and the third protrusion 22 are provided in different shapes, in another form of the package assembly disclosed in fig. 6-9, the third protrusion 22 is formed as two mutually perpendicular segments, and two ends of the third protrusion 22 are provided at two adjacent sides of the second plate 21. And the protruding blocks 23 are arranged at two ends of the third protruding blocks 22, and the protruding blocks 23 on the plurality of third protruding blocks 22 form a bracket with a right angle shape, so that corners of the thin fragile product are limited and supported.

Of course, the shape of the third protrusion 22 is not limited, and the third protrusion 22 may be a folded line type, a curved line type protrusion. But when the package assembly is used for the corners of a product C such as a slim fragile product, both ends of the third protrusion 22 should be disposed at the adjacent both sides of the second plate body 21, respectively.

In an embodiment of the present utility model, the number of grooves 13 provided on the upper case 10 should correspond to the number of the bumps 23, and the grooves 13 should be provided directly above the bumps 23.

Referring to fig. 4, the groove 13 extends from the reinforcing block 14 to the inner wall of the hollow first projection 12.

It should be noted that in one embodiment of the present utility model, the two opposite sides of the bump 23 are also inclined, so as to facilitate the demolding of the lower housing 20.
