Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In this embodiment, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0029] It should be noted that when an element is referred to as being "fixed to", "disposed on" or "connected to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0030] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "mode", "specific mode", or "some modes" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or mode are included in at least one embodiment or mode of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or mode. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or modes in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or modes described in this specification and the features of the different embodiments or modes, without contradiction.
[0031] The utility model application provides a self-curling storage packaging bag, such as Figures 1 to 6 As shown, it includes an upper film 1001, a middle interlayer automatic winding sheet 1002, a lower film 1003 and an inner cavity opening 1004 of the packaging bag.
[0032] The middle interlayer automatic rolling pieces 1002 are arranged on both sides of the packaging bag to make the packaging bag roll up and be stored.
[0033] The middle interlayer automatic winding sheet 1002 is heat-sealed together with the upper film 1001 and the lower film 1003 to form a heat-sealed area.
[0034] The inner cavity opening 1004 of the packaging bag is arranged at one end of the packaging bag for loading and unloading the contents in the packaging bag.
[0035] In specific implementation, when the packaging bag of the utility model is filled with contents, the packaging bag is in a straightened state because the content's own structural force is greater than the pre-tightening force of the middle interlayer automatic winding sheet 1002. During use, as the contents are taken out, the packaging bag automatically curls up and is stored from the untorn end under the pre-tightening force of the middle interlayer automatic winding sheet 1002.
[0036] According to the embodiment provided by the utility model, the width and length of the middle interlayer automatic winding sheet 1002 are both smaller than the heat sealing area.
[0037] According to the embodiment provided by the utility model, the self-curling storage packaging bag further includes two side seals and a bottom seal 1009 formed by heat-sealing the middle interlayer automatic winding sheet 1002 with the upper film 1001 and the lower film 1003 .
[0038] The two side seals and the bottom seal 1009 together form a three-side seal of the packaging bag.
[0039] It should be noted that the heat sealing method uses heat sealants, and other heat sealing methods can also be used, such as laser heat sealing, ultrasonic heat sealing, high-frequency heat sealing, and electric heat sealing. Heat sealing with heat sealants is a method of bonding two or more layers of plastic materials by hot melting or coating. Heat sealants are often used in packaging bags, food bags, cosmetic bags and other fields. Its advantages are simple operation, low cost, firm joints, and the ability to achieve large-area bonding connections through coating.
[0040] The two side seals include a left seal 1007 and a right seal 1008, which are symmetrically distributed on both sides of the packaging bag.
[0041] The packaging bag adopts a three-side seal design in order to better seal the packaging bag and prevent air from entering, thereby achieving a better preservation effect. Secondly, the advantage of the three-side seal design is that it can better protect the food. Since the packaging bag with a three-side seal design is close to the food, it can effectively prevent the food from contacting with the air, thereby preventing the food from spoiling. At the same time, the packaging bag with a three-side seal design is also more beautiful and easy for consumers to accept. In addition, the three-side seal design also has better practicality and operability. During the production process, the packaging bag with a three-side seal design is easy to seal and not easy to leak, which can better ensure the quality and safety of the food. During the use of consumers, the packaging bag with a three-side seal design is also more convenient to open and easier to use.
[0042] According to the embodiment provided by the utility model, the self-curling storage packaging bag also includes two easy-tear openings.
[0043] The two easy-tear openings are respectively arranged on the edges of the two side sealing strips.
[0044] It should be noted that the two easy-tear openings include a left easy-tear opening 1005 and a right easy-tear opening 1006. The left easy-tear opening 1005 is opened on the edge of the left seal 1007. The right easy-tear opening 1006 is opened on the edge of the right seal 1008.
[0045] The tear-off edge of the packaging bag is usually designed as a cut-off tear-off edge. Specifically, a fold is cut on the packaging bag to facilitate consumers to directly open it when using it. The characteristics of this tear-off edge are simple process, low cost, and suitable for mass production. It can also be designed into other types of tear-off edges, such as zipper tear-off edges, injection-molded tear-off edges, pull-ring tear-off edges, laminating tear-off edges, and precise cut-off tear-off edges.
[0046] According to the embodiment provided by the utility model, the middle interlayer automatic rolling sheet 1002 is wrapped inside the two side sealing strips.
[0047] It should be noted that the width of the middle interlayer automatic winding sheet 1002 is smaller than the width of the two side seals. The length of the middle interlayer automatic winding sheet 1002 is smaller than the length of the two side seals. The middle interlayer automatic winding sheet 1002 is wrapped inside the two side seals and is completely sealed to prevent the middle interlayer automatic winding sheet 1002 from falling off.
[0048] According to the implementation mode provided by the utility model, the pre-tightening force of the middle interlayer automatic winding sheet 1002 is smaller than the structural force of the contents of the packaging bag itself.
[0049] It should be noted that the middle interlayer automatic winding sheet 1002 has a preload force. When the contents are loaded, the self-texture force of the loaded contents is greater than the preload force, so that the middle interlayer automatic winding sheet 1002 is unfolded to complete the loading. When the contents are taken out, the self-texture force of the loaded contents is less than the preload force, so that the packaging bag automatically curls up, thereby realizing the self-curling storage of the packaging bag.
[0050] According to the implementation mode provided by the utility model, the middle interlayer automatic winding sheet 1002 is made of metal.
[0051] It should be noted that the middle interlayer automatic winding sheet 1002 is made of elastic alloy, such as Fe-based high elastic alloy (such as Ni 36 CrTiAl,Ni 36 CrTiAIMo5,Ni 36 CrTiAIMo8, etc.), Cu-based high elastic alloys (such as beryllium copper, copper titanium, phosphor bronze, German silver, etc.), Ni-based high elastic alloys (such as NiBe2, 3π578, Inconel 718, Rene 95, etc.). High elastic alloys have: high elastic limit, high strength, and low hysteresis elastic effect. Depending on the use conditions, they should also have corresponding corrosion resistance, temperature resistance, fatigue resistance, non-magnetic, high conductivity and other properties. At the same time, other elastic metal materials can also be used.
[0052] According to the embodiment provided by the utility model, a compression sealing chain is provided at the opening of the inner cavity opening 1004 of the packaging bag.
[0053] The compression seal chain is used to seal the opening of the packaging bag.
[0054] It should be noted that after a portion of the food is consumed, the inner opening 1004 of the packaging bag is sealed by pressing the sealing chain to prevent the food from spilling and becoming damp, so that the opening can be opened and the seal can be closed at any time for consumption.
[0055] According to the implementation mode provided by the utility model, when the packaging bag is curled up, the arc is not less than 2π.
[0056] According to the implementation mode provided by the utility model, when the packaging bag is curled up, the circular diameter is no more than 20 mm.
[0057] It should be noted that the arc of the middle interlayer automatic winding sheet 1002 when curled is not less than 2π, and the circular diameter is not greater than 20 mm.
[0058] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
[0059] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
