[0002] The data book is used for keeping picture and file data, such as contract, clipping, music score and paper data, and the inner page of the data book is a data bag, and the paper data can be inserted into the data bag for keeping, and each file is stored in an independent data bag, which can avoid damage and dirt.

[0003] In the prior art, the data bag of the inner page of the data book is made by water ring blown film, that is, each inner page includes two layers of films, and the three edges of the two layers of films are sealed, and only the upper edge is left open for placing file data, and then a plurality of inner pages are overlapped and ultrasonic welded with the outer shell of the data book, and the usual method is to weld the middle part of the inner page to the back ridge of the outer shell of the data book, so that the data bag of the original whole inner page is divided into two small bag bodies on the left and right, that is, two inner pages with the same size as the outer shell of the data book are formed.

[0004] In actual production, ultrasonic welding can realize at most 20 layers of films, and if the welding exceeds 20 layers, the inner bag will fall off the page, and the data book of the prior art has a welding position of two layers of original inner pages, which means that only 10 original inner pages can be welded each time, and 20 pages of inner pages with the same size as the outer shell of the data book are formed. At present, the data book of 20 pages cannot meet the market demand, and the data book of more than 20 pages will also have the phenomenon of falling off the page in the production by the current market technology. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is to provide a data book, which can reduce the number of layers of welded films, improve the welding quality and avoid the phenomenon of falling off the page when welding the same number of inner pages, or in other words, can increase the number of welded inner pages while ensuring the welding quality.

[0006] The technical solution of the utility model is to provide a data book, which includes an outer shell and a plurality of inner pages, each of which includes a lower layer of film, the left and right parts of the lower layer of film are paved with an upper layer of film, the middle part of the lower layer of film is not paved with an upper layer of film and is provided with a book welding strip, and the book welding strip is used for welding the inner page to the outer shell; the left side edge and the right side edge and the lower side edge of the lower layer of film and the upper layer of film on the left side are respectively provided with a left bag body side seal, a left bag body welding strip and a bottom welding strip, and form a left bag body, and the upper end of the left bag body is provided with a left bag body upper opening; the right side edge and the left side edge and the lower side edge of the lower layer of film and the upper layer of film on the right side are respectively provided with a right bag body side seal, a right bag body welding strip and a bottom welding strip, and form a right bag body, and the upper end of the right bag body is provided with a right bag body upper opening.

[0007] Compared with the prior art, the data book has the following advantages: the middle part of the lower film is not paved with the upper film and is provided with the book mounting welding strip, that is, the data book, the position of welding of each inner page has only one layer of film, which means that when the same number of inner pages are welded, the data book can reduce the number of layers of welded film by half, improve the welding quality and avoid the phenomenon of page falling, and also means that while the welding quality is ensured, the data book can increase the number of welded inner pages by one time.

[0008] Preferably, the lower film of the left bag body is in the same height and coincides with the upper film, and the lower film of the right bag body is in the same height and coincides with the upper film. With this structure, the front and back of the paper data in the left bag body and the right bag body are covered by the film, and the same protection can be obtained.

[0009] Preferably, the left bag body welding strip is continuous and the head and tail of the left bag body welding strip are connected with the upper opening and the bottom welding strip of the left bag body respectively; and the right bag body welding strip is continuous and the head and tail of the right bag body welding strip are connected with the upper opening and the bottom welding strip of the right bag body respectively. With this structure, the left bag body and the right bag body only have one upper end opening for taking and placing the paper data, and the paper data can be prevented from sliding out of the bag body of the inner page and being separated from the protection of the front and back films to the greatest extent.

[0010] Preferably, the left bag body welding strip is continuous, the tail of the left bag body welding strip is connected with the bottom welding strip, the head of the left bag body welding strip is not connected with the upper opening of the left bag body, and the right side of the left bag body forms a left bag body side opening which is communicated with the upper opening of the left bag body; and the right bag body welding strip is continuous, the tail of the right bag body welding strip is connected with the bottom welding strip, the head of the right bag body welding strip is not connected with the upper opening of the right bag body, and the left side of the right bag body forms a right bag body side opening which is communicated with the upper opening of the right bag body. With this structure, if the lower film and the upper film are in the same height and coincide and are connected only at the upper opening of the left bag body, the two layers of films are difficult to be separated due to electrostatic adsorption and atmospheric pressure, and it is inconvenient to put the paper data into the left bag body by opening the opening of the left bag body; and due to the existence of the left bag body side opening, the upper right corner of the upper film and the lower film can be easily separated, so the opening of the left bag body can be easily opened by fingers to put the data. The right bag body is the same, and due to the existence of the right bag body side opening, the upper left corner of the upper film and the lower film can be easily separated, that is, when the data is placed, the opening of the right bag body can be easily opened by fingers.

[0011] Preferably, the book mounting welding strip is continuous and the head and tail of the book mounting welding strip are connected with the upper side and the lower side of the lower film respectively. With this structure, the welding operation is simple and the welding effect is reliable.

[0012] Preferably, the book mounting welding strip is not continuous, and the head and tail of the book mounting welding strip are connected with the upper side and the lower side of the lower film respectively. With this structure, the welding length is shortened and the welding difficulty is reduced, but the upper end and the lower end of the inner page can be firmly connected to the shell to ensure the welding effect.

[0013] Preferably, the lower side edge of the upper layer film of the left bag body coincides with and is welded to the lower side edge of the lower layer film, and the upper side edge of the upper layer film of the left bag body is lower than the upper side edge of the lower layer film; the lower side edge of the upper layer film of the right bag body coincides with and is welded to the lower side edge of the lower layer film, and the upper side edge of the upper layer film of the right bag body is lower than the upper side edge of the lower layer film. With this structure, since the upper side edge of the upper layer film of the left bag body is lower than the upper side edge of the lower layer film, the lower layer film can be easily separated from the top end of the upper layer film, so that the opening of the left bag body can be easily twisted open by a finger, and paper materials can also be directly inserted into the left bag body from the top end of the upper layer film; the right bag body is the same, since the upper side edge of the upper layer film of the right bag body is lower than the upper side edge of the lower layer film, the lower layer film can be easily separated from the top end of the upper layer film, so that the opening of the right bag body can be easily twisted open, and paper materials can also be directly inserted into the right bag body from the top end of the upper layer film.

[0014] Preferably, the upper side edge of the upper layer film of the left bag body is not parallel to the upper side edge of the lower layer film, and the upper side edge of the upper layer film of the right bag body is not parallel to the upper side edge of the lower layer film. With this structure, not only can the lower layer film be easily separated from the top end of the upper layer film, so that the opening of the left bag body or the right bag body can be easily twisted open, but also since the upper side edge of the upper layer film is obliquely arranged and is longer than the length of the upper opening of the bag body, the redundancy of the width of the paper materials is also large, which facilitates the insertion of the paper materials from the top end of the upper layer film.

Embodiment 3

[0029] The difference between the booklet of this embodiment and the booklet of Embodiment 1 is that the upper side of the upper film 1-2 of the left pocket 2 is lower than the upper side of the lower film 1-1, and the lower side of the upper film 1-2 of the left pocket 2 and the lower side of the lower film 1-1 are still coincident and welded. Thus, the lower film 1-1 can be easily separated from the top end of the upper film 1-2, i.e., the opening of the left pocket 2 can be easily twisted open by a finger to put the documents into the left pocket, or the paper documents can be directly inserted into the left pocket 2 from the top end of the upper film 1-2.

[0030] Similarly, the upper side of the upper film 1-2 of the right pocket 3 is lower than the upper side of the lower film 1-1, and the lower side of the upper film 1-2 of the right pocket 3 and the lower side of the lower film 1-1 are still coincident and welded. Similarly, the lower film 1-1 can be easily separated from the top end of the upper film 1-2, so that the opening of the right pocket can be easily twisted open, or the paper documents can be directly inserted into the right pocket 3 from the top end of the upper film 1-2. Embodiment 4
