specific Embodiment approach

[0016] Specific implementation methods: 1. A water-soluble chalk mold, which is sequentially spliced ​​by the left, middle and right templates to form a plurality of small chalk tubes with a back cover. Optionally: (1) small chalk tubes do not distinguish between big and small heads; (2) small chalk tubes It is very long and can accommodate multiple pieces of chalk; (3) a breaking device is provided in the small chalk tube to incompletely divide the small chalk tube into a plurality of identical parts, and each part can accommodate a piece of chalk. (See Figure 1-2 )

[0017] Traditional chalk, in order to facilitate demoulding, are equipped with small and large heads. When demolding, tap the small head, and the chalk will fall out of the mold. This mold is different from the traditional mold. On the one hand, it adopts the half-tube splicing technology. On the other hand, the pen holder is longer than the traditional chalk, and there is a breaking device in the middle, so ...

Abstract

The invention provides a packing method for water-soluble chalks and a corresponding molding and packing article thereof, and belongs to the field of teaching equipment. By improving a mold and designing a packing platform and special paper for packing, the packed water-soluble chalk is provided, and the use comfort level of the water-soluble chalks is improved.

Description

technical field [0001] The invention belongs to the field of teaching appliances, and in particular relates to a disposal device and method for improving the comfort of water-soluble chalk. Background technique [0002] In order to solve the greasy and sticky problem of water-soluble chalk, many chalk holders have appeared. However, due to the stickiness of the water-soluble chalk itself, the holder is easy to block and difficult to clean, which affects the service life of the holder and the popularity of the water-soluble chalk. Contents of the invention [0003] The inventor noticed that the chalk holder can be discarded, and another idea is used to solve the greasy and sticky problem of water-soluble chalk, that is, to pack each piece of chalk. Low packaging efficiency and high cost are the black hands of this creation. Therefore, this solution not only provides a comfortable packaging chalk, but also transforms the mold, designs a special packaging paper and packagin...
