Technical Field
[0001] The utility model relates to the technical field of packaging bags, in particular to a side-opening dust-proof packaging bag. Background Art
[0002] Existing packaging bags for sanitary products such as diapers are often provided with tearing openings on the bag body for taking out the diapers. When in use, the diapers in the packaging bag can be taken out by simply tearing the tearing openings.
[0003] For example, the authorization announcement number: CN203127368U discloses a packaging bag with an easy-tear opening, including a bag body, and the top and middle of the side of the bag body are provided with easy-tear notches. The prior art provides a tearing notch on the side wall of the bag body to achieve the technical effect of quickly taking out the items in the bag.
[0004] However, the inventors have found through summarizing in actual production life that the prior art still has the following technical problems:
[0005] Due to the lack of shielding for the tear in the prior art, when the tear remains open for a long time after being torn, dust and the like can easily enter the bag through the tear, thereby contaminating the remaining diapers in the bag. Utility Model Content
[0006] The utility model provides a side-opening dust-proof packaging bag, which can solve the technical problem that the articles remaining in the bag body are easily contaminated because the tearing opening cannot be closed after opening.
[0007] This application provides the following technical solutions:
[0008] A side-opening dust-proof packaging bag comprises a sealed bag body formed by a top surface, a bottom surface, and a side wall, wherein the top of the side wall extends upward to form a circle of skirt, and the height of the skirt is higher than the top surface; the side wall comprises side surfaces arranged opposite to each other in pairs and end surfaces arranged opposite to each other in pairs; the left and right ends of the top surface are bent and extended downward to be fixedly connected to the inner walls of the end surfaces, and there is a certain gap between the bent and extended parts and the end surfaces; a tearing hole is arranged on the side wall near the top surface, and the vertical distance between the tearing hole and the top surface is smaller than the vertical distance between the top of the skirt and the top surface.
[0009] Beneficial effect: a circle of skirt is formed by extending the side wall upward, and there is a tear on the side wall near the top surface. The vertical distance between the tear and the top surface is smaller than the vertical distance between the top of the skirt and the top surface. This ensures that the flipped skirt can effectively cover the tear. When the tear is opened and is in an open state for a long time, the flipped skirt is used to protect the tear to prevent dust and the like from entering.
[0010] In addition, the gaps between the bending parts at both ends of the top surface and the inner walls at both ends of the skirt can ensure that the skirt can be effectively turned over.
[0011] Furthermore, a triangular blocking piece is provided at the end of the bent extension at one end of the top surface, and the position of the triangular blocking piece corresponds to the position of the tearing opening.
[0012] Beneficial effect: A triangular baffle is provided at the end of the bent extension, and the position of the baffle is made to correspond to the position of the tearing hole, so that when taking out items from the bag through the tearing hole, the lower end of the triangular baffle can be brought out from the tearing hole to cover the tearing hole, thereby improving the dustproof effect.
[0013] Furthermore, the triangular baffle is fitted with the end surface.
[0014] Beneficial effect: This arrangement makes it easy to bring the lower end of the triangular baffle out of the tear hole when taking out items from the bag through the tear hole, thereby covering the tear hole; if the lower end of the triangular baffle is not brought out of the tear hole, the triangular baffle can be ensured to droop naturally, and can still play a role in covering and preventing dust from the tear hole.
[0015] Furthermore, the bag body and the triangular baffle are made of the same flexible material.
[0016] Beneficial effect: This makes it easy to take the lower end of the triangular blocking piece out from the tearing hole when taking out items from the bag body, thereby forming a dust-proof effect on the tearing hole.
[0017] Furthermore, the tearing opening is arranged on one side of the bag body, and the tearing opening is parallel to the top surface.
[0018] Beneficial effect: Such arrangement of the tearing opening is conducive to ensuring that the tearing opening is arranged on the side wall of the bag body so that the articles in the bag body can be easily taken out, and that the tearing opening can be covered after the skirt edge is turned over.
[0019] Furthermore, the tearing opening is arranged on an end surface of the bag body, and the tearing opening is parallel to the top surface.
[0020] Beneficial effect: This arrangement can ensure that the tearing opening is covered by the turned-over skirt, thereby preventing dust and the like from entering the bag body.
[0021] Furthermore, a triangular blocking piece is provided at one end of the top surface, and the position of the triangular blocking piece corresponds to the position of the tearing opening.
[0022] Beneficial effect: By using a triangular baffle plate set on the top surface, and making the position of the baffle plate correspond to the position of the tear hole, when taking out diapers and other items in the packaging bag from the tear hole, the diapers can use friction to bring out part of the triangular baffle plate, so that the triangular baffle plate passes through the tear hole to cover the tear hole, and together with the rolled up skirt edge, it forms double protection for the tear hole, further improving the protection effect.
[0023] Furthermore, a handle is provided on the inner wall of the skirt.
[0024] Beneficial effect: The handles provided on the inner wall of the skirt can facilitate carrying and taking the packaging bag, which can effectively improve the convenience of the packaging bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is further described in detail through specific implementation methods:
[0033] The markings in the drawings of the specification include: bag body 1, top surface 11, top surface end 111, triangular baffle 112, sealing line 113, side surface 12, end surface 13, skirt 2, tearing hole 3, and handle 4.
[0034] Embodiment 1
[0035] like Figure 1 , Figure 2 As shown, the side-opening dustproof packaging bag includes a sealed bag body surrounded by a top surface, a bottom surface, and side walls. The bag body can be in a barrel-shaped, rectangular, cube-shaped, etc. shape. This embodiment is specifically described in a rectangular shape.
[0036] The side walls of the bag body 1 include side faces 12 arranged opposite to each other in pairs and end faces 13 arranged opposite to each other in pairs; wherein the two side faces 12 are an integral structure with the top and bottom faces, and the heat-pressing sealing positions are respectively located at the bottom face, the two end faces and both ends of the top face.
[0037] Specifically, the lower ends of the two side surfaces 12 are bent relative to each other and heat-pressed to form the bottom surface. The left and right ends of the two side surfaces 12 are bent relative to each other and heat-pressed to form the left and right end surfaces 13; and the connection position of the bends forms the sealing line 113. The bottom of the end surface 13 is heat-pressed and sealed with the bottom surface.
[0038] The left and right ends of the top surface 11 are bent downward and extended to be hot-pressed and sealed with the inner wall of the end surface 13. For easier understanding, as shown in FIG. Figure 2 As shown, the position of the heat-pressing sealing line between the top end 111 of the bag body and the end surface 13 is lower than the horizontal position of the top surface 11, so that a gap is formed between the bend of the top surface 11 and the end surface 13, making the top surface 11 smoother, the heat-pressing sealing line more concealed, and the top more beautiful.
[0039] The top of the side wall extends upward to form a circle of skirt 2. In order to improve the structural strength, the skirt 2 is a double-layer structure. The double layer can be the side wall of the bag body 1 extending upward folded inward. After setting it as a double-layer structure, it is convenient to set a handle 4 on the inner wall of the skirt 2 to ensure that the packaging bag has good structural strength when the handle 4 is used to take out the packaging bag.
[0040] A tearing opening 3 is provided on the side surface 12 near the top surface 11, and the tearing opening 3 is actually a tearing line for facilitating tearing open the packaging bag. The tearing opening 3 is parallel to the top surface 11, the length of the tearing opening 3 is smaller than the length of the bag body 1, and the vertical distance between the tearing opening 3 and the top surface 11 is smaller than the vertical distance between the top of the skirt 2 and the top surface 11.
[0041] Here’s how to use it:
[0042] When in use, the packaging bag can be torn from the tearing opening 3 to take out the items in the packaging bag. After taking out the items, the skirt 2 is turned outward to cover the tearing opening 3 to prevent dust from entering the packaging bag and contaminating the items in the packaging bag.
[0043] Embodiment 2
[0044] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the difference between this embodiment and the first embodiment is that the tear 3 is arranged at one of the end faces 13 of the bag body 1, and the length of the tear 3 is smaller than the width of the bag body 1. A triangular baffle 112 is arranged in the bag body 1 at a position corresponding to the tear 3. In this embodiment, the triangular baffle 112 is an isosceles triangle, and the bottom edge of the triangular baffle 112 is fixed to the bent extension end of the top surface 11 by hot melt. The triangular baffle 112 blocks the tear 3 and fits with the end face 13; the small triangular area at the lower end of the triangular baffle 112 can pass through the tear 3; specifically, in this embodiment, the triangular baffle 112 and the packaging bag are made of the same flexible material, so that when the items in the packaging bag are pulled, the triangular baffle 112 can be taken out from the tear 3. In other embodiments other than this embodiment, Figure 3 The tear opening 3 located in the middle of the width direction is changed to an eccentric design, so that the tear opening 3 is located on one side of the sealing line 113 of the end surface 13 , thereby avoiding the sealing line 113 .
[0045] Here’s how to use it:
[0046] The tearing opening 3 is torn and enlarged to facilitate taking out the items in the packaging bag from the tearing opening 3. Since the triangular blocking piece 112 is close to the top surface 11 and is basically located near the top position of the topmost item in the bag, when taking out the items, the triangular blocking piece 112 will be brought out of the tearing opening 3; and the subsequent items are basically located below the tearing opening 3, and the hand can be put in when the hand is put in. Figure 6 The middle triangular blocking piece 112 is pushed in and the above-mentioned action is repeated.
[0047] Therefore, in the present technology, if the object is taken out, the lower end of the triangular baffle 112 is brought out from the tearing opening 3 to form Figure 6 Even when the triangular blocking piece 112 is not taken out, its lower end still hangs down naturally to cover the tearing hole 3, and still forms a protective effect. After taking out the items, the skirt 2 is turned down, and the skirt 2 covers the tearing hole 3, and can also form a second layer of protection, thereby achieving a better dustproof effect.
[0048] The above is only an embodiment of the utility model. The utility model is not limited to the field involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
