Description

Fast Kaifeng cover

[technical field]

The utility model relates to a kind of big envelope, particularly relates to a kind of big envelope that is easy to open.

[background technology]

Consult Fig. 1, it is an existing envelope 1, the front cover 11 of envelope 1 is formed with a tear line 12, tear line 12 define one be the slide fastener decorative pattern tear sheet 13, tear sheet 13 and have a pull head 131, remove from envelope 1 will tear sheet 13 for addressee's application of force, and open an envelope 1, two auxiliary tear lines 14 extend to the side of envelope 1 from 12 liang of end opposite of tear line, the addressee remove tear sheet 13 after, tear envelope 1 along auxiliary tear line 14 again, form big opening, make things convenient for the addressee to take out contents such as mail in the envelope 1.Yet the addressee but needs two-step, tears tear line 12 and auxiliary tear line 14 in regular turn, just envelope 1 can be formed big opening, and is desirable not to the utmost in the use.

[utility model content]

The purpose of this utility model is to be to provide a kind of fast Kaifeng cover of opening easily and not damaging content.

The utility model cover that breaks a seal soon comprises: a polygon hollow bag and a cover plate.This bag has a surface and constitutes an open side edges and a plurality of side that seals of this surface-boundary, and this cover plate is connected with in this bag, in order to seal this open side edges.Lay a tear line on this surface, the two ends of this tear line and samely or not same seal side and border on are torn by this tear line, and this surface can be raised by the scope that this tear line enclosed.

The beneficial effects of the utility model are: by lay tear line on the surface of bag, and the two ends of tear line and bag same or not same sealed side and borders on, torn by tear line, the surface is torn the scope that line encloses and can be raised, and forming opening at bag, receiver can take out the object that is placed in the big envelope via opening.

[specific embodiment]

The utility model cover that breaks a seal soon is not limited to envelope, official document envelope/document envelope such as, and Western-style or Chinese style, big size/little size all can be used technological means of the present utility model.Below in conjunction with drawings and Examples the utility model is elaborated:

Consult Fig. 2,3, first embodiment of the present utility model is to be example with the envelope, and big envelope 3 comprises a polygon hollow bag 4 and a cover plate 5.Bag 4 for example is used to take in files such as mail, has two

surfaces

41,42, two

open side edges

43,44, and three

seal side

45,46,47.Open side edges 43 and three is sealed

side

45,46,47 and is constituted surperficial 41 borders, and open side edges 44 and three is sealed 45,46,47 of sides and constituted surperficial 42 borders.Cover plate 5 is connected with in bag 4 in order to sealing open side edges 43,44.Surface 41 offers a form 48, can appear the literal that part is recorded in mail, for example: address of the addressee, name etc., read to make things convenient for the user.

Lay a tear line 61 on the surface 41, the two ends of tear line 61 and the same side 45 that seals are bordered on, and are torn by tear line 61, and surperficial 41 are torn the scope that line 61 enclosed can be raised.Lay another tear line 62 on the surface 42, and the two ends of tear line 62 border on the same side 46 that seals, torn by tear line 62, surperficial 42 are torn the scope that line 62 enclosed also can be raised.

Two

tear lines

61,62 all are circular arc, but amplitude difference, this design is because the mail that is placed in the big envelope 3 is to be strip through folding, cooperate width and Design of

length tear line

61,62 after general mail is folded, make after receiver is torn one of them tear line, the surface can be raised by the scope that this tear line enclosed, and forms the suitably opening of size at bag 4, makes receiver can not lose the mail of mail ground in opening takes out big envelope 3.

Consult Fig. 4, big envelope 3 is to be made by single paper, cut paper and paper is separated out a centre slice 71, three

lateral plates

72,73,74 and a cover plate 5 with four fold lines, cover plate 5 and three

lateral plates

72,73,74 are adjacent and separate with fold line with centre slice 71 respectively, offer form 48 on the centre slice 71, and being provided with tear line 61, lateral plate 72 and centre slice 71 adjacent sides then are provided with another tear line 62.Three

lateral plates

72,73,74 are folded to a side of centre slice 71 along fold line, make lateral plate 72 be stacked and placed on

lateral plate

73,74 tops, and with sticker stickup

lateral plate

73,74 and lateral plate 72 overlappings, can form bag 4 with two

surfaces

41,42, along another fold line cover plate 5 is folded to surperficial 42 tops again, promptly makes big envelope 3.The production method of big envelope 3 is approximately identical to traditional envelope, and different places is that big envelope 3 suppresses

tear line

61,62 on the surface respectively on 41,42, and its processing mode is simple, but can reach the effect that is easy to open big envelope.

In the present embodiment, the two ends of tear line 61 and the same side 45 that seals are bordered on, and the two ends of tear line 62 then border on the same side 46 that seals, and in fact not as limit, the two ends of tear line also can be designed to border on the not same side that seals.In addition, tear line can only be located at two

surfaces

41,42 one of them, also many tear lines can be set on same surface.In addition, in the present embodiment, offer form 48 on the surface 41, in fact also big envelope 3 can be designed to not have form 48.

Shown in Figure 5 is the utility model cover second embodiment of 3 that breaks a seal soon, its unitary construction and first embodiment are roughly the same, different places is that second embodiment is a broken line in surface 42 tear lines of being laid 62 ', in fact, tear line also can be designed to other polygonal shapes not as limit.

In sum, by on the surface of bag, laying tear line, and the two ends of tear line and bag same or not same sealed side and borders on, after receiver is torn tear line, the surface is torn the scope that line encloses can be raised and be formed an opening, and receiver can take out the object that is placed in the big envelope via opening, not only opens big envelope easily, in the opening process, can not undermine the object in the big envelope, so can reach the purpose of this utility model really yet.

The above, it is preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, promptly the simple equivalent of being done according to the utility model claim and utility model description generally changes and modifies, and all still belongs in the scope that the utility model patent contains.
