Description

Technical Field

[0001] This utility model relates to the field of dairy product packaging box technology, specifically to a dairy product aseptic packaging box. Background Technology

[0002] In the field of liquid dairy product packaging, aseptic packaging technology is crucial for ensuring product quality and safety. Currently, most dairy product packaging boxes on the market use individual straws sealed with a lid. However, this packaging method has several drawbacks: firstly, the individual straws are exposed outside the box, making them susceptible to dust and bacteria contamination during transportation and storage, posing hygiene risks; secondly, the simple sealing structure of the box opening makes it easy for milk to spill due to pressure changes when opened, affecting the user experience. Furthermore, traditional packaging boxes often have a flat bottom design, requiring users to repeatedly tilt the box to drink the remaining liquid when it's nearly empty, which is inconvenient, may waste liquid, and the flat structure can cause the straw to slide inside the box, further reducing drinking efficiency. These problems have prompted the industry to urgently need an innovative dairy product packaging solution that balances sealing, hygiene, and ease of use. Utility Model Content

[0011] Preferably, a lid is provided on the outside of the box opening, and the lid is connected to the box opening by a thread.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features a sealing plate that tightly abuts against the inner wall of the box opening, working in conjunction with the abutment plate at the top of the inner tube to form a double seal of "physical barrier + fixed position." In this sealed state, the inner tube is completely enclosed within the box opening, preventing the exposure of traditional independent straws and the potential for dust and bacteria contamination. No additional straw removal is required during use, reducing the risk of secondary contamination. When the sealing plate is removed via the pull ring, milk will not spill from the box opening due to instantaneous pressure changes, enhancing opening safety. The expansion section at the bottom of the inner tube frictionally connects with the inner wall of the outer tube, allowing it to be fixed at any height after being pulled out, preventing the straw from slipping during drinking and eliminating the need for frequent adjustments. The drainage bottom has a funnel-shaped structure with a central indentation, using gravity to flush out any remaining milk from the bottom of the packaging box. Milk is collected at the connecting end, and the suction port is set around the connecting end. Users can completely suck up the remaining milk through the inner tube without tilting the packaging box, reducing waste. The design of the connecting piece and the suction port ensures that the milk flows smoothly into the outer tube. The abutment piece is locked at the top of the outer tube to prevent the inner tube from falling completely into the packaging box during transportation or storage, avoiding situations where users cannot remove the straw. Whether drinking upright, drinking by hand during exercise, or conveniently sucking up the remaining milk, the structural design enables "ready to drink without adjustment". It is especially suitable for office workers, students and other groups with high convenience requirements. The built-in straw and the drainage bottom design simplify the drinking steps to "pull the ring - pull the straw - suck", improving the efficiency of use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-3 This utility model provides the following technical solutions:

[0020] A dairy product aseptic packaging box includes a packaging box 1, a connecting plate 2 is provided in the middle of the top surface of the packaging box 1, a box opening 9 is provided in the middle of the top surface of the connecting plate 2, a box cover 3 is provided outside the box opening 9, the box cover 3 and the box opening 9 are connected by threads, an outer tube 6 is provided inside the box opening 9, an inner tube 7 is slidably provided inside the outer tube 6, and a drainage bottom 8 is provided at the bottom of the inside of the packaging box 1.

[0021] The top end of the outer tube 6 is connected to the box opening 9, and the bottom end of the outer tube 6 is connected to the bottom of the packaging box 1. A connecting end 12 is provided at the bottom end of the outer tube 6.

[0022] The inner tube 7 has a contact plate 10 at its top, and the bottom surface of the contact plate 10 abuts against the top of the outer tube 6. The bottom end of the inner tube 7 has an expansion section 11, which is in frictional contact with the inner wall of the outer tube 6. The box opening 9 has a sealing plate 4 inside, and a pull ring 5 is connected to the top of the sealing plate 4. The bottom surface of the sealing plate 4 abuts against the top end of the inner tube 7.

[0023] Specifically, when the sealing sheet 4 is used to seal the box opening 9, the inner tube 7 is also sealed inside, preventing the straw that is stuck to the outside of the box from accidentally falling off. When the sealing sheet 4 is removed using the pull ring 5, the milk will not spill out of the box opening 9 due to inertia. At this time, the inner tube 7 can be pulled out and you can start drinking. When the inner tube 7 is pulled out, it can be fixed in a certain position on the outer tube 6 due to the influence of the expansion section 11, and will not slide down. At the same time, due to the setting of the abutment piece 10, the inner tube 7 will not fall completely into the inside of the packaging box 1 when sealing the packaging.

[0024] The drainage base 8 has a funnel-shaped structure with a central depression, and the connecting end 12 is located in the middle of the drainage base 8. The top of the connecting end 12 is connected to the outer tube 6, and the bottom of the connecting end 12 is provided with no less than two connecting pieces 13. The connecting pieces 13 are evenly spaced around the bottom of the connecting end 12, and the space between adjacent connecting pieces 13 is a suction port 14. The bottom of the connecting piece 13 is connected to the drainage base 8.

[0025] Specifically, the remaining milk at the bottom of the packaging box 1 is drawn towards the middle of the drainage bottom 8 by gravity. The collected milk gathers at the connection end 12. At this time, the user sucks in the milk through the inner tube 7. The milk enters the outer tube 6 through the suction port 14 at the bottom of the connection end 12, and then is sucked into the user's mouth through the inner tube 7. The remaining milk in the packaging box 1 can be sucked in without adjusting the position of the straw or changing the angle of the packaging box 1, which improves the user's drinking convenience and avoids wasting milk.

[0026] Whether drinking upright, drinking by hand during exercise, or conveniently sucking up leftover milk, the structural design enables "instant drinking without adjustment," making it especially suitable for office workers, students, and other groups with high convenience requirements. The built-in straw and drainage bottom design simplify the drinking process to "pull the ring - pull the straw - suck up," improving efficiency.
