Description

Waterproof box

Technical field:

The utility model relates to a packing container, in particular to a waterproof packing box.

Background technique:

Most of the commodity packaging boxes currently in use are made of paper, and paper packaging boxes are not waterproof and can only pack dry commodities. Therefore, when flower and bird stores sell flowers, potted goods, goldfish, turtles and other products that need to be nourished by water, they are now packaged in paper bags, or filled with a little water in plastic bags. However, the flowers or pots packed in paper bags are easy to wither if they lack water for a long time, and the paper bags can’t pack goldfish and other things that cannot be separated from water for a while; and the plastic bags filled with water are very thin, in case they are accidentally lost on the way If it is broken, it will cause a very embarrassing situation. Therefore existing paper packing box all can not be used for packing those articles that cannot do without moisture for a long time.

Invention content:

In order to overcome the disadvantage that the existing paper packaging box cannot pack water-containing or wet items, the utility model provides a waterproof, leak-proof and foldable waterproof packaging box.

The technical scheme that the utility model solves its technical problem to take is:

A waterproof packaging box is composed of a box body and a leak-proof bag, and the leak-proof bag is sealed on the box opening on the upper edge of the box body along the circumference of the bag opening.

The box body of the waterproof packaging box described in the utility model is constructed by a foldable box blank. The box blank includes four panels constituting the sides of the box body, which are respectively connected to each panel and formed after assembly. There are four tail panels at the bottom of the box body and a glued edge connected to the side of one end panel. There are crease lines between each panel, tail panels, glued edge and adjacent panels; two of the opposite tail panels Each panel is provided with a crease line which can make the end panels fold inward after being folded, and the two end panels are respectively connected with the other two adjacent end panels so as to be inserted into each other to form the bottom of the box body during assembly; The leak-proof bag can be made of plastic or rubber; the connection between the leak-proof bag mouth and the box mouth and between the tail plates connected in pairs can be glued.

Compared with the prior art, the utility model adds a layer of leak-proof bags to the box body of the packaging box, and the box body is constructed of foldable box blanks, so it has the dual functions of waterproof, leak-proof and foldable. Therefore, it has the convenient and practical advantages of being able to hold water-containing and wet articles, being convenient for storage and transportation, and the like.

Detailed ways:

Now in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

First please refer to Fig. 1 for a perspective view of the utility model. The illustrated waterproof packaging box is composed of a box body 1 and a leak-proof bag 2. The box body 1 is an open square carton, and a leak-proof bag 2 is sealed (for example, glued) on the box body along the circumference of the bag mouth. 1 on the box opening 1a along the upper edge, the leak-proof bag 2 can be made of plastic or rubber. Referring to Fig. 2 again, the box body 1 of the waterproof packing box described in the utility model is constructed by a foldable box blank plate 1 '. The illustrated box blank 1' includes four panels 11, 12, 13 and 14, four end panels 21, 22, 23 and 24 and a glued edge 31. Said panels 11, 12, 13 and 14 formed four sides of the box body 1 respectively when the box blank 1' was folded and assembled into the box body 1 (see Fig. 1). The tailboards 21, 22, 23 and 24 are respectively connected on the above-mentioned panels 11, 12, 13 and 14, that is, the tailboard 21 and the panel 11, the tailboard 22 and the panel 12, the tailboard 23 and the panel 13, the tailboard 24 and the panel 14 are respectively connected on the bottom side of each panel; on the two opposite tail panels 21 and 23 among the four panels, a crease line 41 and 43 is respectively provided, when along the crease line 41 When folded with 43, the tail panels 21 and 23 can be folded into the inner cavity of the box body 1 respectively; there is a breach 21b and 23b in the center of the bottom edge of the tail panels 21 and 23, respectively, and the crease lines 41 and 43 respectively come from the inner cavity of the box body 1. The top ends of the notches 21b and 23b are connected to the corners of the tailgates 21 and 23 respectively adjacent to the tailgates 22 and 24, and the crease lines 41 and 43 demarcate the joints 21a and 23a on the tailgates 21 and 23, respectively. The glued edge 31 is connected to the side of the panel 11 at the farthest end, and it is used to bond with the panel 14 at the other end when the box body 1 is assembled, thereby enclosing the four sides of the box body 1 . Crease lines 42 are provided between adjacent panels 11, 12, 13, 14 and glued edges 31; Crease lines 44 are also respectively provided between the tail plate 24 and the panel 14, so as to fold when the box body 1 is assembled.

The assembly of the waterproof packing box described in the utility model is carried out according to the following process. First along the crease lines 42 and 44 the panels on the box blank 1 ' are folded inwardly, and the glued edge 31 is bonded to the inner side of the outer edge of the panel 14, so that the four panels 11, 12, 13 and 14 are surrounded. Four sides (referring to Fig. 1) of synthetic box body 1; Then the junction 21a of tail plate 21 is connected (for example glued) on the outer surface of tail plate 22, and the junction 23a of tail plate 23 is connected likewise (as Bonding) on the outer surface of the tail plate 24, the tail plate 21 and 22, 23 and 24 are connected in twos; then the two connected tail plates are opposite to each other with the gaps 21b, 23b on it, and the plates intersect They are inserted into each other to form the bottom of the box body 1. The assembled bottom can be seen in Figure 1 and Figure 3; finally, the outer circumference of the leak-proof bag 2 is coated with adhesive and bonded to the box body 1 On the box mouth 1a of upper edge, must make the sack of leak-proof bag 2 and the box mouth 1a of box body 1 completely seal and match during bonding, can not have the place of leakage.

After the waterproof packaging box of the utility model is assembled, it can be folded when it needs to be stored or transported before use, so as to reduce the occupied space. The method of folding is, along the direction shown by the arrow on Fig. 3, i.e. the direction of the crease lines 41 and 43 on the tail plates 21 and 23 at the bottom of the box body 1, reversely pull the two corners of the box body 1 to both sides, and make The crease lines 41 and 43 are folded into the inner cavity of the box body 1, and the tail plates 21 and 22, 23 and 24 connected in pairs are folded into the inner cavity and folded between the four panels 11, 12, 13 and 14 , and its state is shown in Figure 4.

The waterproof packaging box described in the utility model is provided with a liner leak-proof bag, so it can be used to pack water-containing and wet items, and can even be placed in clean water to place flowers, potted plants and other plants, or aquatic animals such as goldfish and golden turtles. animals; moreover, it folds down for easy storage and transport when not in use. Therefore, the utility model has the advantages of practical convenience, wide application, convenient storage and transportation, etc., and is suitable for packaging wet, water-containing and liquid articles.
