Abstract
Description
Technical Field
[0001] The utility model relates to the field of shopping paper bags, in particular to a shopping paper bag with a double plate sandwiching an intermediate film. Background Art
[0002] Hand-held shopping paper bags are a common type of container in major business districts, and are particularly widely used in the clothing consumption industry. Shopping paper bags are generally not products that are used for a long time. Their main function is to wrap products, and their main function time is the time from the business district to the consumer's residence. The material of shopping paper bags is often single-layer kraft paper, which is sufficient for use in most cases.
[0003] However, the existing kraft paper shopping bags will be difficult to meet current business needs in some niche scenarios, because shopping paper bags are used in large quantities, but their shapes and materials are basically unified. However, shopping paper bags are one of the indispensable promotional links in the commercial links of various fast-moving consumer goods, so downstream merchants who purchase shopping paper bags have expectations for shopping paper bags of different materials and shapes. Utility Model Content
[0004] The problem to be solved by the utility model is to provide a shopping paper bag with a double plate sandwiched with an intermediate film. Compared with the traditional one-piece kraft paper shopping paper bag, it is composed of three parts, and the intermediate belt constitutes both the handle and a part of the bag body. The width of the handle is narrowed and the thickness is thickened, which can meet the requirements of the handle, and at the same time, the shape of the intermediate belt is not complicated, ensuring the simplicity of processing.
[0005] In order to solve the above problems, the utility model provides a shopping paper bag with a double plate sandwiched with an intermediate film. In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:
[0006] A shopping paper bag with a double plate sandwiched with an intermediate film comprises: a vertical hard plate, wherein two vertical hard plates are arranged parallel to each other; a middle belt connecting the two vertical hard plates, wherein the middle belt has a handle section which is not directly connected to the vertical hard plates, and the middle belt, excluding the handle section, together with the vertical hard plates, forms a bag body with an opening at the top; the hardness of the middle belt itself is lower than that of the vertical hard plates; the handle sections themselves have crescent-shaped folded strips folded towards each other on both sides, and the crescent-shaped folded strips are bonded to the middle belt body; and from the root of the handle section to the middle of the handle section, the crescent-shaped folded strips folded towards each other gradually narrow the width of the handle section.
[0007] The beneficial effect of adopting the above technical solution is that the shopping paper bag of this technical solution includes two typical different parts. Compared with the traditional one-piece kraft paper shopping paper bag, this technical solution has commercial differentiation. The general shopping paper bag can be compared to a hexahedron with five wrapping surfaces and one opening surface. The two vertical hard plates constitute two wrapping surfaces, and the middle belt constitutes three relatively small wrapping surfaces, which totals five wrapping surfaces. At the same time, the middle belt also constitutes a handle.
[0008] Technically, this technical solution has an advantage, which is that it emphasizes that the middle belt is small in hardness and relatively flexible, and provides a folding method of its own. That is, the vertical hard board is relatively rigid and not easy to fold, while the middle belt between the two vertical hard boards is relatively easy to press and fold. When folding, the two vertical hard boards are moved closer to each other, and the middle belt shrinks naturally.
[0009] Last but not least, the crescent-shaped folding strip narrows the width of the handle, making it easier to hold, while thickening the handle and improving its tensile strength. Moreover, the shape and manufacturing of the handle section are not complicated, and only require moderate deformation, folding, and bonding.
[0010] As a further improvement of the present invention, when the middle belt is in a plane unfolded state, the width of the middle belt at the handle section is uniform, and the crescent-shaped fold strip and the middle belt body are divided by an arc fold.
[0011] The beneficial effect of adopting the above technical solution is that the specific shape of the handle section is explained.
[0012] As a further improvement of the present invention, the maximum width of a single crescent-shaped folding strip is equal to one quarter of the width of the handle section in the flat unfolded state.
[0013] The beneficial effect of adopting the above technical solution is that the width of the narrowest part of the handle section is just half of the original width, and the thickness of the handle section is double.
[0014] As a further improvement of the utility model, the middle belt forms a closed loop shape connected end to end when it is in a three-dimensional state connecting two vertical hard plates; when the middle belt is in a plane unfolded state, the handle section is located in the middle of the middle belt.
[0015] The beneficial effect of adopting the above technical solution is that the entire shopping bag is composed of three independent parts, and the number of parts is relatively small.
[0016] As a further improvement of the present invention, when the middle belt is in a planar unfolded state, the two ends of the handle section are side sections of the middle belt, and the end of the side section away from the handle section is the bottom section of the middle belt; when the middle belt is in a three-dimensional state connecting two vertical hard boards, the side sections constitute the sides of the bag body, and the bottom sections are bonded to each other and constitute the bottom of the bag body.
[0017] The beneficial effect of adopting the above technical solution is that it explains how the middle belt of the plane forms a closed loop state and constitutes the principle of three wrapping surfaces and a handle of the bag body.
[0018] As a further improvement of the utility model, the side sections are provided with integrated upper folding strips on both sides, and the bottom sections are provided with integrated lower folding strips on both sides; the upper folding strips and the lower folding strips are bonded to the vertical hard board.
[0019] The beneficial effect of adopting the above technical solution is that the upper folding strip and the lower folding strip can have a sufficient contact area with the vertical hard board, thereby facilitating gluing.
[0020] As a further improvement of the utility model, the shape of the upper folding strip is an isosceles trapezoid, the shape of the lower folding strip is a right-angled trapezoid, and the height of the isosceles trapezoid is equal to the height of the right-angled trapezoid.
[0021] The beneficial effect of adopting the above technical solution is that since the middle belt is in a three-dimensional flipped state during actual use, the trapezoidal shapes of the upper folding strips and the lower folding strips facilitate their bonding with the vertical hard board.
[0022] As a further improvement of the present invention, the side section and the bottom section are divided by a transverse fold, the upper fold strip and the middle belt body are divided by an upper longitudinal fold, and the lower fold strip and the middle belt body are divided by a lower longitudinal fold.
[0023] The beneficial effect of adopting the above technical solution is that the scratches facilitate the folding of the middle belt according to the designated area.
[0024] As a further improvement of the utility model, the thickness of the middle belt is less than the thickness of the vertical hard board, and the vertical hard board is a single layer of kraft paper or corrugated paperboard.
[0025] As a further improvement of the present invention, the middle belt is made of plastic film.
[0026] The beneficial effect of adopting the above technical solution is that the plastic film has good flexibility, thickness and tensile strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is a further detailed description of the present invention in conjunction with specific embodiments:
[0036] In order to achieve the purpose of the utility model, a shopping paper bag with a double plate sandwiched with an intermediate film comprises: a vertical hard plate 1, two vertical hard plates 1 are arranged parallel to each other; an intermediate band 2 connects the two vertical hard plates 1, the intermediate band 2 has a handle section 201 that is not directly connected to the vertical hard plates 1, and the intermediate band 2, except for the handle section 201, together with the vertical hard plates 1, constitutes a bag body with an open top; the hardness of the intermediate band 2 itself is less than that of the vertical hard plates 1; the two sides of the handle section 201 itself have crescent-shaped folding strips 208 folded toward each other, and the crescent-shaped folding strip 208 is bonded to the main body of the intermediate band 2; from the root of the handle section 201 to the middle of the handle section 201, as shown in FIG. Figure 5 As shown, the crescent-shaped folding strips 208 folded toward each other gradually narrow the width of the handle section 201 .
[0037] The beneficial effect of adopting the above technical solution is that the shopping paper bag of this technical solution includes two typical different parts. Compared with the traditional one-piece kraft paper shopping paper bag, this technical solution has commercial differentiation. A general shopping paper bag can be compared to a hexahedron with five wrapping surfaces and one opening surface. The two vertical hard plates constitute two wrapping surfaces, and the middle belt constitutes three relatively small wrapping surfaces, which totals five wrapping surfaces. At the same time, the middle belt also constitutes a handle. Technically speaking, this technical solution has an advantage, emphasizing that the hardness of the middle belt is small and relatively flexible, that is, it provides a folding method that belongs to itself. That is, the vertical hard plate is relatively rigid and not easy to fold, while the middle belt between the two vertical hard plates is relatively easy to press and fold. When folding, the two vertical hard plates are close to each other, and the middle belt shrinks naturally. Finally and most importantly, the crescent-shaped folding strip narrows the width of the handle, making it easier to hold, and at the same time thickens the thickness of the handle to improve the tensile strength of the handle. Moreover, the shape and manufacturing of the handle section are not complicated, and only require moderate deformation, folding and bonding.
[0038] like Figure 3 As shown, in other embodiments of the present invention, when the middle belt 2 is in a planar unfolded state, the width of the middle belt 2 at the handle section 201 is uniform, and the crescent-shaped fold strip 208 is divided from the main body of the middle belt 2 by an arc fold 204 .
[0039] The beneficial effect of adopting the above technical solution is that the specific shape of the handle section is explained.
[0040] In some other embodiments of the present invention, the maximum value of the width of a single crescent-shaped fold strip 208 is equal to one quarter of the width of the handle section 201 in the flat unfolded state.
[0041] The beneficial effect of adopting the above technical solution is that the width of the narrowest part of the handle section is just half of the original width, and the thickness of the handle section is double.
[0042] like Figure 1 , Figure 5 As shown, in other embodiments of the present invention, the middle belt 2 forms a closed loop shape connected end to end when it is in a three-dimensional state connecting two vertical hard boards 1; when the middle belt 2 is in a planar unfolded state, the handle section 201 is located in the middle of the middle belt 2.
[0043] The beneficial effect of adopting the above technical solution is that the entire shopping bag is composed of three independent parts, and the number of parts is relatively small.
[0044] In other embodiments of the present invention, when the middle belt 2 is in a planar unfolded state, the two ends of the handle section 201 are the side sections 202 of the middle belt 2, and the end of the side section 202 away from the handle section 201 is the bottom section 203 of the middle belt 2; when the middle belt 2 is in a three-dimensional state connecting two vertical hard boards 1, the side section 202 constitutes the side surface of the bag body, such as Figure 1 As shown, the bottom sections 203 are bonded to each other and form the bottom of the bag.
[0045] The beneficial effect of adopting the above technical solution is that it explains how the middle belt of the plane forms a closed loop state and constitutes the principle of three wrapping surfaces and a handle of the bag body.
[0046] In other embodiments of the present invention, the side section 202 has integrated upper folding strips 209 on both sides, and the bottom section 203 has integrated lower folding strips 210 on both sides; the upper folding strips 209 and the lower folding strips 210 are bonded to the vertical hard board 1 .
[0047] The beneficial effect of adopting the above technical solution is that the upper folding strip and the lower folding strip can have a sufficient contact area with the vertical hard board, thereby facilitating gluing.
[0048] like Figure 3 , Figure 4 As shown, in some other embodiments of the present invention, the upper folding strip 209 is shaped as an isosceles trapezoid, and the lower folding strip 210 is shaped as a right-angled trapezoid, and the height of the isosceles trapezoid is equal to the height of the right-angled trapezoid.
[0049] The beneficial effect of adopting the above technical solution is that since the middle belt is in a three-dimensional flipped state during actual use, the trapezoidal shapes of the upper folding strips and the lower folding strips facilitate their bonding with the vertical hard board.
[0050] like Figure 3 , Figure 4 As shown, in other embodiments of the present invention, the side section 202 and the bottom section 203 are divided by a transverse fold 205, the upper fold strip 209 and the main body of the middle band 2 are divided by an upper longitudinal fold 206, and the lower fold strip 210 and the main body of the middle band 2 are divided by a lower longitudinal fold 207.
[0051] The beneficial effect of adopting the above technical solution is that the scratches facilitate the folding of the middle belt according to the designated area.
[0052] In some other embodiments of the present invention, the thickness of the middle belt 2 is less than the thickness of the vertical hard board 1, and the vertical hard board 1 is a single layer of kraft paper or corrugated cardboard.
[0053] In other embodiments of the present invention, the middle belt 2 is made of plastic film.
