Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically an eight-side sealed flat-bottom self-standing pet food preservation packaging bag. Background Technology

[0002] Eight-side sealed, flat-bottomed, self-standing pet food packaging bags are a common type in the pet food packaging industry. Their flat-bottom design allows them to stand upright, making storage and retrieval convenient, while the eight-side seal enhances sealing performance. They are typically made of food-grade composite film, effectively blocking moisture, light, and air, delaying oxidation and spoilage of pet food. Suitable for various pet food forms, including granules and powders, they meet pet owners' basic needs for food preservation and convenient storage, and are widely used in pet food production and sales.

[0003] Utility model patent CN223086629U discloses an eight-side seal packaging bag. This bag includes a bag body, a garbage bag, and connecting components. The bag body includes a protective layer and a sealing layer. The sealing layer is disposed on the inner surface of the protective layer and is used for sealing the sides of the bag body and heat-sealing the bag opening. The garbage bag is fixedly connected to the outer surface of the protective layer. Two sets of connecting components are provided, each including a connecting ring and a connecting buckle. The connecting ring is fixedly connected to the outer surface of the protective layer, and the connecting buckle is fixedly connected to the inner surface of the garbage bag. This eight-side seal packaging bag has a garbage bag inside, allowing users to temporarily store garbage inside the bag when using it, thus facilitating the use of the packaging bag.

[0004] The current eight-side seal packaging bag allows for retrieval of food only by opening and closing the bag opening. For large-sized packaging bags containing granular pet food, each use requires first moving the entire bag of food and then retrieving the food by tilting it. The operation is cumbersome and labor-intensive, and it is also easy to lose control of the amount of food being retrieved or for food to spill. In view of this, we propose an eight-side seal flat bottom self-standing pet food preservation packaging bag. Utility Model Content

[0005] The purpose of this utility model is to provide an eight-sided sealed, flat-bottomed, self-standing pet food preservation packaging bag to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An octagonal sealed flat-bottom self-standing pet food preservation packaging bag includes a bag body. A fixing seat is tightly bonded to the outer surface of the bottom of the bag body. A protrusion is provided on the fixing seat and is connected to the inside of the bag body. A discharge device is detachably connected to the protrusion. The discharge device includes a connecting sleeve installed on the protrusion, a rotating shaft coaxially disposed inside the connecting sleeve, a rotating handle coaxially installed at the end of the rotating shaft, and an end cap. A discharge pipe is connected to the bottom position of the end of the connecting sleeve. The end cap is threaded to the bottom end of the discharge pipe. A spiral blade is fixed on the outer periphery of the rotating shaft.

[0007] Preferably, the first end of the connecting sleeve is provided with a handle, which is sleeved on the outside of the convex sleeve and threadedly connected to the convex sleeve. In this design, the handle facilitates the assembly and disassembly of the connecting sleeve and the convex sleeve, while the threaded connection ensures a stable and airtight connection.

[0008] Preferably, the end of the rotating shaft passes through the connecting sleeve and extends to the outside of the connecting sleeve, and rotating the handle can drive the rotating shaft to rotate circumferentially inside the connecting sleeve; In this setting, simply rotating the handle will drive the shaft to rotate, making it easy to operate and eliminating the need to handle packaging bags for material retrieval.

[0009] Preferably, the connecting sleeve has a cavity, the end of the cavity is closed and the beginning is open, and a baffle is fixed on the outer peripheral surface of the tail of the rotating shaft, the baffle is in contact with the end cavity wall of the cavity; In this configuration, the cavity provides space for the shaft to be installed and rotated, while the baffle restricts the axial movement of the shaft, ensuring stable material discharge.

[0010] Preferably, the tail end of the rotating shaft is provided with a convex shaft, which axially passes through the rotating handle and extends to the outside of the rotating handle, and a retaining spring is engaged on the outer surface of the end of the convex shaft. In this configuration, the cam provides mounting positioning for the handle, and the retaining spring prevents the handle from falling off during use.

[0011] Preferably, a cuboid-shaped insert is provided at the connection between the end of the rotating shaft and the beginning of the convex shaft, and a slot adapted to the shape of the insert is opened on the front end face of the rotating handle. The insert is inserted into the slot, and the axial displacement between the rotating shaft and the rotating handle is limited by the cooperation between the insert and the slot. In this setup, the insert and slot work together to transmit torque while limiting axial offset between them, ensuring synchronous rotation.

[0012] Preferably, the end of the connecting sleeve is provided with a through-hole, the diameter of which is larger than the end size of the insert, and the insert passes through the through-hole. In this setting, the clearance hole prevents interference between the insert block and the connecting sleeve, ensuring smooth rotation of the shaft.

[0013] Preferably, the outer surface of the outer side of the convex sleeve and the outer peripheral surface of the bottom end of the discharge pipe are both provided with threads, and the thread size is the same, so that the end cap can be threadedly connected to the convex sleeve alone. In this setup, the consistent thread size enables universal end caps, and the discharging device can be disassembled to seal the protrusion, ensuring food preservation.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This eight-sided sealed flat-bottom self-standing pet food preservation packaging bag, through the set discharge device, allows large-sized granular pet food packaging bags to be emptied without handling or tilting. Rotating the handle drives the rotating shaft and spiral blades to rotate, which can orderly discharge the food in the bag from the discharge pipe. The operation is convenient and labor-saving, and the amount of material taken out can be precisely controlled to avoid food spillage. 2. This eight-side sealed flat-bottom self-standing pet food preservation packaging bag, through the setting of a convex sleeve with the same thread size as the discharge pipe and a separable discharge device and end cap, allows the end cap to be directly threaded onto the convex sleeve after the discharge device is not in use and is disassembled, forming a reliable seal for the bag's discharge port without the need for additional sealing components, ensuring the hygiene and dryness of food storage.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 An octagonal-seal, flat-bottomed, self-standing pet food preservation packaging bag includes a bag body 100. A fixing seat 110 is tightly adhered to the outer surface of the bottom of the bag body 100. A protrusion 111 is provided on the fixing seat 110, which is connected to the interior of the bag body 100. The protrusion 111 serves as a connecting bridge between the bag body 100 and a discharge device 200, providing a channel for food discharge. The discharge device 200 is detachably connected to the protrusion 111. The detachable design facilitates the cleaning, maintenance, or replacement of the discharge device 200, improving its reusability. The discharge device 200 includes a connecting sleeve 210, a rotating shaft 220, a rotating handle 230, and an end cap 240.

[0018] like Figure 1 , Figure 3 and Figure 4 As shown, in this utility model, the first end of the connecting sleeve 210 is provided with a handle 212, which is sleeved on the outside of the protrusion 111 and threadedly connected to the protrusion 111. The handle 212 makes it easier to assemble and disassemble the connecting sleeve 210 and the protrusion 111. The bottom position of the end of the connecting sleeve 210 is connected to a discharge pipe 213, which can guide the discharged food and prevent the food from scattering when taking out the material. The end cap 240 is threadedly connected to the bottom end of the discharge pipe 213. The end cap 240 can form a seal on the discharge pipe 213 to prevent the food in the bag from getting damp, contaminated or leaking out when no material is taken out.

[0019] like Figure 3 and Figure 4 As shown, specifically, a cavity 211 is provided inside the connecting sleeve 210. The end of the cavity 211 is closed and the beginning is open. The rotating shaft 220 is coaxially arranged inside the cavity 211 of the connecting sleeve 210. The end of the rotating shaft 220 passes through the connecting sleeve 210 and extends to the outside of the connecting sleeve 210. Rotating the handle 230 can drive the rotating shaft 220 to rotate circumferentially inside the connecting sleeve 210. The operation of driving the rotating shaft 220 by the handle 230 is simple and can pick up the material without handling the packaging bag. A spiral blade 221 is fixed on the outer periphery of the rotating shaft 220. The beginning of the spiral blade 221 extends into the bag body 100. When the spiral blade 221 rotates, it can push the granular pet food in the bag body 100, so that the food is discharged in an orderly manner and avoids the problem of spillage when pouring and picking up the material.

[0020] like Figure 3 and Figure 4 As shown, further, a baffle 222 is fixed on the outer peripheral surface of the tail of the rotating shaft 220. The baffle 222 fits against the end cavity wall of the cavity 211. The baffle 222 can restrict the axial movement of the rotating shaft 220, ensuring that the spiral blade 221 is in a stable position during the discharge process and avoiding the impact of axial movement on the discharge efficiency. A convex shaft 224 is provided at the tail end of the rotating shaft 220. The convex shaft 224 provides a positioning base for the installation of the rotating handle 230, which facilitates the precise docking of the rotating handle 230 and the rotating shaft 220. A cuboid-shaped insert 223 is provided at the connection between the end of the rotating shaft 220 and the beginning of the convex shaft 224. The cuboid-shaped insert 223 can transmit torque, ensuring the synchronous rotation of the rotating shaft 220 and the rotating handle 230.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the front end face of the handle 230 is provided with a slot 231 that matches the shape of the insert 223. The insert 223 is inserted into the slot 231. The axial displacement between the shaft 220 and the handle 230 is limited by the cooperation between the insert 223 and the slot 231. The matching shape of the insert 223 and the slot 231 can ensure that the two are tightly connected, preventing the handle 230 from spinning freely relative to the shaft 220. At the same time, limiting the axial displacement can further improve the stability of rotation transmission. The convex shaft 224 axially passes through the handle 230 and extends to the outside of the handle 230. A retaining spring 225 is engaged on the outer surface of the end of the convex shaft 224. The retaining spring 225 can axially limit the handle 230, preventing the handle 230 from falling off the convex shaft 224 during use and improving the reliability of the structure.

[0022] like Figure 3 and Figure 4 As shown, it is worth noting that the end of the connecting sleeve 210 is provided with a through hole 214. The diameter of the hole 214 is larger than the end size of the insert 223. The insert 223 passes through the hole 214, which provides space for the insert 223 to move, avoids interference between the insert 223 and the end of the connecting sleeve 210, and ensures that the rotating shaft 220 rotates smoothly without obstruction.

[0023] like Figure 5 As shown, it is worth noting that the outer surface of the convex sleeve 111 and the outer circumferential surface of the bottom end of the discharge pipe 213 are both provided with threads, and the thread size is the same, so that the end cap 240 can be threadedly connected to the convex sleeve 111 alone. The thread design of the same size realizes the universality of the end cap 240. When the discharge device 200 is disassembled, the end cap 240 can be directly installed on the convex sleeve 111 to seal the bag body 100, ensuring the freshness of the food in the bag, without the need for additional sealing components.

[0024] In this embodiment, the eight-side sealed flat-bottom self-standing pet food preservation bag is used as follows: First, align the handle 212 of the discharging device 200 with the protruding sleeve 111 and tighten it, ensuring the opening of the discharging tube 213 faces downwards, thus completing the assembly of the discharging device 200 and the bag body 100. At this time, the end cap 240 is in a sealed state of the discharging tube 213. Then, when it is needed, rotate and remove the end cap 240 on the discharging tube 213 to prepare for discharging. Next, manually rotate the handle 230, which connects to the slot 23 via the insert 223. The rotation of the rotating shaft 220 is driven by the 1, and the spiral blades 221 on the rotating shaft 220 rotate synchronously, pushing the pet food in the bag 100 to the discharge pipe 213 and discharging it. The amount of food taken out can be adjusted by controlling the rotation time of the handle 230 according to the needs. Finally, after the food is taken out, the end cap 240 is screwed back onto the discharge pipe 213 to complete the seal. If long-term storage or cleaning of the discharge device 200 is required, the discharge device 200 can be removed by rotating the handle 212, and then the end cap 240 can be screwed onto the protrusion 111 to seal the bag 100.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
