Embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belong to the scope of the utility model protection.
Embodiment:As shown in figures 1-13, a kind of self-sealing packing case, including chest body 1 and its top, the opening of bottom
Portion, the opening portion are solid respectively with the upper cover plate 11 and lower cover 21 to sealed opening portion, the edge of the upper and lower cover plate
It is fixed to connect upper strip of paper used for sealing 31 and lower strip of paper used for sealing 41, it is provided with the lower strip of paper used for sealing 41 at least provided with a cover plate 411, the cover plate 411
Projection 412, the slot 311 for raised 412 insertion is accordingly provided with the upper strip of paper used for sealing 31, and the cover plate 411 is relative
It can be bent in lower strip of paper used for sealing 41.A kind of self-sealing packing case of the utility model, including a chest body 1, its shape are commonly designed
For square or rectangle, its top and bottom forms opening portion respectively, and opening portion is put down successively by bent upper and lower cover plate
So as to which opening portion be covered, then the projection 412 on lower strip of paper used for sealing cover plate is inserted into the slot 311 on upper strip of paper used for sealing again, it is described
Slot can be through hole, and so as to which upper and lower cover plate to be snapped together to the purpose for reaching seal case, the utility model need not profit
Packing case can just be sealed with auxiliary materials such as other adhesive tapes, easy to use, good seal performance, and can be repeated several times and make
With meeting environmental requirement, the utility model is particularly suitable for use in the plasticity packing case that the hollow honeycomb sheet material of plasticity folds.The cover plate
A 411 only sides are connected with lower strip of paper used for sealing 41, therefore cover plate is free to bending.It is pressed in when by upper strip of paper used for sealing 31 on lower strip of paper used for sealing 41
When, cover plate 411 can up be turned over, after pressing, then cover plate be turned down to come and projection 412 thereon is fastened on into inserting for upper strip of paper used for sealing
In groove 311, so when box sealing, cover plate is different from other positions of lower strip of paper used for sealing, and it is placed on strip of paper used for sealing.This is special
Structure design, easily will be convex on cover plate even if the support for not having any supporter also to utilize upper and lower strip of paper used for sealing in casing
Rise and snap onto in slot., can be by the thickness of the surrounding (such as its shape corresponds to cover plate) of slot in order to more convenient to use
It is more neat when so cover plate is covered, attractive in appearance if must be thinner.
Wherein, the upper and lower cover plate relative edge is provided with low order mating surface 111, is provided with the inside of the upper and lower strip of paper used for sealing described in supplying
What mating surface 111 was inserted plugs together frame.The mating surface of the upper and lower cover plate, which heats to insert respectively, is sandwiched in plugging together for the upper and lower strip of paper used for sealing
Inframe.The upper strip of paper used for sealing is fixed on upper cover plate, and the lower strip of paper used for sealing is fixed on lower cover, and the mode that both connect can phase
Together.The edge of the upper and lower cover plate is provided with the mating surface of slightly below main body, and accordingly the inward flange of the upper and lower strip of paper used for sealing is set
Plug together frame, during combination, mating surface is plugged together into inframe, because cover plate and strip of paper used for sealing can all use plastic material, therefore can be led to
Easy hot melt processing is crossed, both can be firmly stuck together, the phenomenon that will not be fallen off.
As viewed in figures 5-8, the both ends of upper strip of paper used for sealing 31 are provided with cramp 61, and casing side face is provided with corresponding with the cramp
Lock 51, the cramp can bend and detain and be fixed on the lock.The cramp 61 is provided with cramp hole 611, the lock
51 are provided with the inserted sheet 511 that can pass through the cramp hole, and the inserted sheet 511 is provided with bonnet lock hole 512.The strip of paper used for sealing on described
Both ends are provided with the cramp that can be bent, and are provided with lock in the side corresponding section of casing, when upper and lower strip of paper used for sealing has fastened
Afterwards, upper strip of paper used for sealing, is further fixed on casing by the inserted sheet for cramp being bent and being caught on lock, improves the flat of casing entirety
Whole degree and sealing.The bonnet lock hole 512 being provided with by inserted sheet can lock casing, prick it such as by objects such as bands
Rise.Certain cramp can be equally located on lower strip of paper used for sealing, and the lock can also be located at the upper and lower surface of casing, not limit to
In the side provided with chest.
As shown in Figure 3 and Figure 4, on the upper strip of paper used for sealing 31 at least provided with a snap fit 312, on the lower strip of paper used for sealing 41 accordingly
Provided with the neck 413 for snap fit engaging.The snap fit and notch that the upper and lower strip of paper used for sealing is provided with, for for its fastening
When auxiliary positioning, beneficial to the operation of fastening, while also contribute to improve the overall sealing property of chest.It is right on the lower strip of paper used for sealing 41
Claim ground to be provided with two cover plates 411, two slots 311 are accordingly provided with the upper strip of paper used for sealing 31.Cover plate on lower strip of paper used for sealing is main
It is to be designed according to the length of casing, can is one or more, it is convenient to detain both for the ease of the positioning of upper and lower strip of paper used for sealing
Close, neck can be designed with the both sides of each cover plate and is caught in for the snap fit being provided with upper strip of paper used for sealing.Certainly equally can also be in upper envelope
Bar is provided with neck, and snap fit is provided with lower strip of paper used for sealing.The both sides of the cover plate 411 respectively symmetrically are provided with the neck 413,
The corresponding position of upper strip of paper used for sealing 31 is provided with snap fit 312.Reclinate flange 313 is provided with the side of upper and lower strip of paper used for sealing.Upper and lower envelope
Bar be provided be bent downwardly and with the orthogonal flange in side, can be complete by the opening portion edge of casing in conjunction with cramp
Envelope, further increase the overall sealing of casing, while be also possible to prevent external contaminants and enter box house.
The utility model operating process is as follows:After vanning, lower cover 21 is placed on to the opening of casing first, put down
Upper cover plate 11, and the cover plate 411 on the lower strip of paper used for sealing 41 of lower cover edge is dug upwards, then by the upper envelope on upper cover plate 11
Bar 31 is flattened on lower strip of paper used for sealing 41, and the snap fit 312 on upper strip of paper used for sealing is inserted correspondingly into the neck 413 that lower strip of paper used for sealing is provided with, then
