Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid storage, and more specifically to a perforated storage bag. Background Technology
[0002] With societal development, storage bags are becoming increasingly widely used in daily life, especially in areas such as breast milk storage and liquid food packaging. Storage bags are typically made of plastic film and offer advantages such as being lightweight, having good sealing properties, and being low in cost.
[0003] However, existing storage bags still have some problems in practical use: their fixed structure, such as limited width and shape, makes them difficult to adapt to different scenarios. Furthermore, after filling with liquid, air often remains inside the bag, and the existing venting structure is poorly designed, leading to inconvenient venting and affecting the storage effect and subsequent use of the liquid. Additionally, the bags are mostly smooth and flat, resulting in low friction between the hand and the bag when held. The lack of effective leverage points makes them difficult to grip, especially when the liquid is heavy or the hands are wet, causing the bag to easily slip from the hand and spill. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an improved perforated storage bag, which addresses the shortcomings of existing storage bags, such as inconvenience in venting and difficulty in gripping, thus affecting the effectiveness of use.
[0005] To achieve the above objectives, this utility model employs the following technical means:
[0006] A perforated storage bag, comprising:
[0007] The bag body includes a first part and a second part that cooperate to form a liquid storage cavity for storing liquid. Therefore, the sides of the first part and the second part along the length direction of the bag body are on the same straight line, while the other sides of the first part and the second part along the length direction of the bag body are not on the same straight line. The sides of the first part and the second part that are not on the same straight line along the length direction of the bag body are rounded and transitioned. The first part and the second part cooperate to form a liquid storage cavity inside the bag body.
[0008] A sealing strip is provided in the first part and is used to open and close the liquid storage cavity;
[0009] The first hollow section is for inserting a finger and is located on the inner side of one edge of the second part.
[0010] In some embodiments, the width of the first portion along the width direction of the bag body is smaller than the width of the second portion along the width direction of the bag body.
[0011] In some embodiments, the width of the first portion along the width direction of the bag body is greater than the width of the second portion along the width direction of the bag body.
[0012] In some embodiments, a first tear line is further included, which is disposed on the first portion and extends along the width direction of the bag body and is located above the sealing strip, and the bag body is provided with first tear openings located at both ends of the first tear line.
[0013] In some embodiments, a second cutout portion is further included, which is disposed on the inner side of the other edge of the first portion and is symmetrical to the first cutout portion about the central symmetry line of the first portion.
[0014] In some embodiments, the second perforated portion has an arcuate protrusion that protrudes toward the central symmetry line of the first portion and cooperates with the first perforated portion to facilitate air release from the bag.
[0015] In some embodiments, the device further includes a protrusion disposed on one side edge of the second portion and communicating with the interior of the second portion. The protrusion is inclined relative to the width direction of the bag body and the angle of inclination with the width direction of the bag body is α, wherein the range of α is 5-55°.
[0016] In some embodiments, the inner side of the end of the protrusion away from the bag body has a second tear line, the second tear line penetrates the protrusion along the width direction of the protrusion, and the two sides of the protrusion are provided with second tear openings that cooperate with the second tear line.
[0017] In some embodiments, a third hollow portion located below the protrusion is provided on the inner side of one side edge of the second portion.
[0018] In some embodiments, the third hollow portion is shaped as a polygon, a circle, or an ellipse.
[0019] The beneficial effects of this utility model are as follows: By setting the first and second parts with different widths, gripping areas of varying widths can be formed. Furthermore, the asymmetrical structure of the first and second parts facilitates the natural flow of liquid under gravity, reducing liquid residue inside the bag. The perforated design prevents slippage during gripping and improves stability during pouring and squeezing operations, reducing bag shaking. The V-shaped guide groove formed by the symmetrical arc-shaped protrusions of the first and second perforated parts helps air escape from the bag, improving ease of use. Compared with existing technologies, the perforated storage bag structure of this utility model is more rationally designed and more convenient to use, effectively solving the problems existing in the use of current perforated storage bags.

[0033] In this embodiment, a perforated storage bag is disclosed, comprising:
[0034] The bag body 100 includes a first part 110 and a second part 120 that cooperate to form a liquid storage cavity 130 for storing liquid. Therefore, the sides of the first part 110 and the second part 120 along the length direction of the bag body 100 are on the same straight line, while the other sides of the first part 110 and the second part 120 along the length direction of the bag body 100 are not on the same straight line. The sides of the first part 110 and the second part 120 that are not on the same straight line along the length direction of the bag body 100 are rounded and transitioned. The first part 110 and the second part 120 cooperate to form the liquid storage cavity 130 inside the bag body 100 for storing liquid.
[0035] A sealing strip 200 is disposed on the first part 110 and used to open and close the liquid storage chamber 130;
[0036] The first hollowed-out portion 300 is used for inserting a finger and is located on the inner side of one edge of the second portion 120.
[0037] In one possible embodiment of this utility model, the perforated storage bag includes a bag body 100, a sealing strip 200, and a first perforated portion 300.
[0038] In one or more possible embodiments of this utility model, the bag body 100 is formed by a first part 110 and a second part 120 through a hot-pressing process to create an internal liquid storage cavity 130. The liquid storage cavity 130 is used to store liquids such as sauces, milk, breast milk, and detergents. The left side L1 of the first part 110 and the second part 120 along the length of the bag body 100 is collinear, while their right side edges are not. The right side edge of the first part 110 is L2, and the right side edge of the second part 120 is L3. L2 and L3 are connected by an arc transition to distribute the stress after the bag body 100 stores liquid and prevent edge tearing.
[0039] In one possible embodiment of this utility model, the width of the first portion 110 along the width direction of the bag body is smaller than the width of the second portion 120 along the width direction of the bag body. In some embodiments, the width W1 of the first portion 110 along the width direction of the bag body 100 is smaller than the width W2 of the second portion 120, so that the second portion 120 forms a wider gripping area.
[0040] In one possible embodiment of this utility model, the width of the first portion 110 along the width direction of the bag body is greater than the width of the second portion 120 along the width direction of the bag body. In some embodiments, the width W3 of the first portion 110 along the width direction of the bag body 100 is greater than the width W4 of the second portion 120, so that the first portion 110 forms a wider gripping area. By setting the first portion 110 and the second portion 120 with different widths as described above, it is easy to cooperate with the structure of the first hollow portion 300. It can be adapted to different types of liquids, and the shape difference can be adapted to the gripping habits of different users, reducing liquid residue inside the bag and preventing slippage.
[0041] In one or more possible embodiments of this utility model, the sealing strip 200 is disposed in the first part 110, and the liquid storage chamber 130 can be repeatedly opened and closed, solving the problem that traditional disposable sealed bags cannot be reused. This makes it suitable for scenarios where liquids are repeatedly removed and placed, such as when storing breast milk or other liquids. The sealing strip 200 can be made of food-grade silicone material, possessing good sealing performance and reusability. The sealing strip 200 can be butt-fitted or interlocking; when the user presses both sides of the sealing strip 200, it can fit tightly together to form a seal. The width of the sealing strip 200 can be adjusted according to the size of the bag body 100, typically 5-15 mm, to ensure a good sealing effect.
[0042] In one or more possible embodiments of this utility model, a first easy-tear line 400 is further included, which is disposed on the first portion 110 and extends along the width direction of the bag body 100 and is located above the sealing strip 200. The bag body 100 is provided with first easy-tear openings 410 located at both ends of the first easy-tear line 400. In some embodiments, the first easy-tear line 400 is a laser-cut easy-tear line or a perforated easy-tear line, so that the perforated storage bag can be neatly torn along a preset path when it needs to be opened, without causing irregular damage to the bag body 100, which facilitates the diversion of liquid.
[0043] In one or more possible embodiments of this utility model, a second hollow portion 500 is further included. The second hollow portion 500 is disposed on the inner side of the other edge of the first portion 110 and is symmetrical to the first hollow portion 300 about the central symmetry line of the first portion 110. In some embodiments, the first hollow portion 300 and the second hollow portion 500 are structurally symmetrical, and the shapes of the first hollow portion 300 and the second hollow portion 500 can be mutually symmetrical circles, straight grooves, curved grooves, polygons, irregular shapes, etc. In some embodiments, the shapes of the first hollow portion 300 and the second hollow portion 500 can be mutually symmetrical, such as squares, rectangles, etc., to satisfy the purpose of allowing fingers to be inserted for easy gripping of the bag body 100, further improving stability during operations such as pouring and squeezing.
[0044] In one possible embodiment of this utility model, to improve the venting effect of the bag body 100, the second hollow portion 500 has an arc-shaped protrusion 510 that protrudes towards the central symmetrical line of the first portion 110 and cooperates with the first hollow portion 300 to facilitate venting of the bag body 100. As shown in the figure, both the first hollow portion 300 and the second hollow portion 500 are symmetrically provided with arc-shaped protrusions. The upper parts of the two arc-shaped protrusions and the interior of the first portion 110 form a V-shaped gooseneck venting shape, which helps to vent the air inside the bag body 100.
[0045] In one or more possible embodiments of this utility model, a protrusion 600 is further provided on one side edge of the second portion 120 and communicates with the interior of the second portion 120. The protrusion 600 is inclined relative to the width direction of the bag body 100, and the angle of inclination with the width direction of the bag body 100 is α, wherein α ranges from 5 to 55°. In some embodiments, the protrusion 600 is provided at a apex corner of the second portion 120 and has an arc-shaped transition fit with the connection of the first portion 110.
[0046] In some embodiments, the tilt angle α of the protrusion 600 is 5°, which makes the liquid flow more smoothly.
[0047] In some embodiments, the tilt angle α of the protrusion 600 is 35°, which is the optimal drainage angle, allowing the liquid in the bag 100 to be drained more thoroughly.
[0048] In some embodiments, the tilt angle α of the protrusion 600 is 45°. This angle design ensures drainage effect while making the structure of the protrusion 600 more compact.
[0049] In one possible embodiment of this utility model, a second easy-tear line 610 is provided on the inner side of the end of the protrusion 600 away from the bag body 100. The second easy-tear line 610 penetrates the protrusion 600 along its width direction, and second easy-tear openings 620 that cooperate with the second easy-tear line 610 are provided on both sides of the protrusion 600. The above design allows users to choose whether to use the protrusion 600 as needed, increasing the flexibility of the product.
[0050] In one or more possible embodiments of this utility model, a third hollow portion 700 is provided on the inner side of one edge of the second part 120, located below the protrusion 600. By providing the third hollow portion 700, it can cooperate with the first hollow portion 300 and the second hollow portion 500 to facilitate the user to insert multiple fingers into the corresponding hollow structures, satisfying the usage or gripping habits of different users and improving the stability of holding the bag body 100.
[0051] In one possible embodiment of this utility model, the third hollow portion 700 is shaped as a polygon, a circle, or an ellipse. By setting these shapes, the needs of the auxiliary grip function can be met, and the different shapes can adapt to the gripping habits of different users. For example, a circle is suitable for users with thicker fingers, while a polygon is suitable for scenarios requiring a more stable grip. In some embodiments, the edge of the third hollow portion 700 is integrally connected to the pressing edge of the second portion 120, ensuring the overall structural strength of the product. In some embodiments, the third hollow portion 700 and the pressing edge of the second portion 120 are not connected, so that a channel for liquid flow is formed inside the third hollow portion 700 and the second portion 120.
[0052] The hollow storage bag disclosed in this utility model has a reasonable structural design, is easy to use, has good sealing performance, and good grip performance. It is suitable for the storage and transportation of various liquids, and is especially suitable for the packaging of liquid products in the fields of food, cosmetics, and medicine.
