Description

Moisture-proof soap powder packaging bag

technical field

The utility model relates to a packaging bag structure, in particular to a soap powder packaging bag structure with moisture-proof function.

Background technique

In the prior art, soap powder is generally packed in bags. When in use, the bag needs to be cut open to facilitate the pouring of the soap powder. After pouring the soap powder, most people will not tie the mouth of the bag tightly, and the soap powder will Long-term contact with the air, or even being splashed by water accidentally splashed during laundry, will not only easily cause the soap powder to be damp and agglomerated, but also easily cause the soap powder to deteriorate and affect the use effect of the soap powder. If you want to tie the mouth of the bag If it is tight, you need to use additional tools such as clips. Furthermore, the sack formed after the soap powder packaging bag is cut is soft, and when the soap powder is poured out, the soft sack is prone to collapse and deformation, thereby causing the user to pour the soap powder too much, not only Cause the waste of soap powder, also easily damage clothing.

Utility model content

In order to solve the above problems, the utility model provides a moisture-proof soap powder packaging bag. The moisture-proof soap powder packaging bag of the utility model can effectively prevent the soap powder from being damp, and is also convenient for pouring the soap powder, and has a simple structure and is easy to implement.

The technical scheme that the utility model adopts in order to solve its technical problem is:

A packaging bag for moisture-proof soap powder, comprising a bag body, the bag body is provided with a mouth, and a hollow plastic ring is provided, one end of the hollow plastic ring is connected to the mouth of the bag, and the other end of the hollow plastic ring has an inner Thread, provided with a cover, the cover has external threads, the external threads of the cover match the internal threads of the hollow plastic ring, and the cover is matched with the internal threads through the external threads And close the described hollow plastic circle.

Preferably, the pocket opening is located at the upper part of the pocket body.

Further, the hollow plastic ring is a hollow cylinder, the end face of the other end of the hollow plastic ring is a ring-shaped end face, the cover body is integrally formed by a connecting post and an end cover, and the connecting post is Cylindrical, the external thread is located on the side of the connecting post, the diameter of the end cap is larger than the diameter of the connecting post, and the end cap can close the circular end face of the hollow plastic ring.

Furthermore, it may be that the end cover has two opposite surfaces, which are respectively an inner surface and an outer surface, and a protrusion is provided on the inner surface of the end cover at a position corresponding to the annular end surface. An annular protruding strip, the annular end surface is provided with an annular groove matching the annular protruding strip, and the annular protruding strip can be embedded in the annular concave in the slot.

Furthermore, it is also possible that a protruding annular rib is provided on the annular end surface, and the end cap has two opposite surfaces which are respectively an inner surface and an outer surface, and the end cap On the inner surface of the inner surface corresponding to the position of the annular convex strip, there is an annular groove matching the annular convex strip, and the annular convex strip can be embedded in the ring in the groove.

The beneficial effects of the utility model are: the moisture-proof soap powder packaging bag of the utility model has a bag opening on the bag body, and a hollow plastic ring is connected to the bag mouth, and a cover is used to close the hollow plastic ring. The soap powder needs to be unscrewed to take out the cover. After pouring, just screw on the cover again to seal the bag, so it can effectively prevent the soap powder from getting wet, and the hollow plastic ring is hard and not easy to deform. It is convenient to take out the soap powder.
