Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and more specifically, to a highly stable conical barrel. Background Technology

[0002] Conical drums are a common type of packaging container used for storing and transporting various liquids, powders, and other materials. They are widely used in chemical, food, and pharmaceutical industries.

[0003] However, because the bottom area of ​​the conical barrel is smaller than the top area, the contact area between the bottom of the barrel and the surface on which it is placed is smaller. During stacking or transportation, due to factors such as vehicle bumps and unstable stacking center of gravity, the barrels will be displaced by external forces, making them prone to tipping over and collisions, and the barrels are easily deformed and damaged. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a highly stable conical barrel.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a highly stable conical barrel, including an outer barrel body, an inner barrel body inside the outer barrel body, the barrel wall of the inner barrel body gradually increasing in thickness from top to bottom, a buffer cavity being formed between the inner barrel body and the outer barrel body, an outer contact ring and an inner contact ring being provided at the bottom of the outer barrel body, a receiving cavity being formed between the inner contact ring and the outer contact ring, a barrel lid being provided at the top of the outer barrel body, a groove being provided at the top of the barrel lid, and a liquid outlet being provided in the groove. When stacked, the upper inner contact ring and the outer contact ring both abut against the bottom surface of the groove, and the lower liquid outlet is located in the receiving cavity. Two symmetrically arranged buckles are rotatably connected to the peripheral wall of the barrel lid, and two through slots are symmetrically opened on the outer contact ring. When stacked, the lower buckle flips upward and engages in the through slot of the outer contact ring.

[0006] The present invention is further configured such that: the openings of the inner barrel and the outer barrel are fixedly connected, the bottom diameter of the inner barrel is smaller than the bottom diameter of the outer barrel, and the inner barrel, the outer barrel, the outer contact ring, and the inner contact ring are all integrally formed by injection molding of HDPE material.

[0007] The present invention is further configured such that: the circumferential wall of the bucket lid is provided with a plurality of fixing buckles in a circular array; the top of the outer bucket body is integrally injection molded with a protrusion; the fixing buckles and the protrusion are interlocked with each other; and the bucket lid is provided with a limiting strip to restrict the displacement of the fixing buckles.

[0008] The present invention is further configured such that: the diameter of the outer contact ring is the same as the diameter of the groove; the centers of the outer contact ring and the inner contact ring are located on the same vertical line; the distance between the outer contact ring and the inner contact ring is the same as the diameter of the liquid outlet; and the liquid outlet is threadedly connected to an end cap.

[0009] The present invention is further configured such that: the buckle is located between adjacent fixing buckles, the two buckles are respectively arranged vertically opposite to the two through slots, the buckle, fixing buckle, limiting strip, bucket lid and liquid outlet are all integrally formed by injection molding of HDPE material, the limiting strip and several fixing buckles are stamped to form tear marks, and the buckle is stamped to form several flip marks.

[0010] In summary, this utility model has the following beneficial effects: When the outer ring at the bottom of the outer barrel engages with the groove at the top of the lid, it can effectively limit the displacement of the upper barrel relative to the lower barrel. When the buckle engages in the through groove, it can further enhance the limiting effect, thereby reducing the risk of the stacked barrels sliding and falling over, and improving the stability during stacking and transportation. The design of the inner barrel wall gradually increasing in thickness from top to bottom enhances the structural strength of the bottom, enabling it to better withstand the stacking pressure. The buffer cavity between the inner and outer barrels can effectively absorb the impact force when subjected to external collisions, reducing the possibility of barrel deformation and damage.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: Highly stable conical barrel, such as Figure 1 and Figure 2As shown, the device includes an outer barrel 1 and an inner barrel 2 inside the outer barrel 1. The diameter of the inner barrel 2 decreases from top to bottom, with the top diameter of the inner barrel 2 being larger than the bottom diameter. The bottom of the inner barrel 2 is fixedly connected to the bottom of the outer barrel 1. The openings of the inner barrel 2 and the outer barrel 1 are also fixedly connected, forming a single piece during injection molding to ensure a tight seal between the inner barrel 2 and the outer barrel 1. The top of the inner barrel 2 is fixedly connected to the top of the outer barrel 1. The inclination angle of the inner barrel 2 wall is greater than that of the outer barrel 1 wall, resulting in a smaller bottom diameter of the inner barrel 2 than the bottom diameter of the outer barrel 1. The center of the inner barrel 2 and the center of the outer barrel 1 are located on the same vertical line, creating a buffer cavity 3 between the inner barrel 2 and the outer barrel 1. The buffer cavity 3 effectively absorbs the impact force when the barrel is subjected to external force, providing a good cushioning effect, reducing the impact force on the inner barrel 2, thereby protecting the safety of the materials inside the barrel and reducing the risk of barrel deformation and material leakage due to collisions.

[0015] like Figures 1-3 As shown, the wall thickness of the inner barrel 2 gradually increases from top to bottom, thereby enhancing the pressure resistance of the bottom of the barrel and lowering the center of gravity, thus improving the stability of the barrel. The inner barrel 2 and the outer barrel 1 are integrally injection molded from HDPE material. HDPE material has the characteristics of high strength, wear resistance, and corrosion resistance. The integral molding process reduces the connection gaps between parts, avoids stress concentration, and makes the overall strength of the barrel higher, less prone to deformation and damage, and has a longer service life. The bottom of the outer barrel 1 is integrally injection molded with an outer contact ring 4 and an inner contact ring 5. The inner contact ring 5 and the outer contact ring 4 have the same thickness, and the centers of the outer contact ring 4 and the inner contact ring 5 are located on the same vertical line, so that the inner contact ring 5... An annular cavity 6 is formed between the outer ring 5 and the inner ring 4. The top of the outer barrel 1 is provided with a barrel cover 7, which is made of HDPE material. The top of the barrel cover 7 is integrally injection molded with a groove 8. A liquid outlet is reserved in the groove 8 during injection molding. The liquid outlet is threadedly connected to an end cap 14. The diameter of the outer ring 4 is the same as the diameter of the groove 8. The distance between the outer ring 4 and the inner ring 5 is the same as the diameter of the liquid outlet. When stacked, the upper inner ring 5 and the upper outer ring 4 abut against the bottom surface of the groove 8. The lower liquid outlet is located in the cavity 6, thus forming a tight nested structure, which can effectively limit the displacement of the upper barrel relative to the lower barrel and prevent it from slipping due to vehicle shaking during transportation.

[0016] like Figures 1-3As shown, the peripheral wall of the bucket lid 7 is rotatably connected by two symmetrically arranged buckles 9. The two buckles 9 are integrally formed during the injection molding of the bucket lid 7. After molding, the buckles 9 are stamped by a stamping machine to form two turning lines 16. Two through grooves 10 are symmetrically opened on the outer ring 4. The two through grooves 10 are pre-formed during the injection molding of the outer ring 4. The two buckles 9 are respectively arranged vertically opposite to the two through grooves 10. When several buckets are stacked, the lower buckle 9 flips upward and engages with the upper through groove 10 of the outer ring 4, so that several buckets can be connected together when stacked, further strengthening the restriction of displacement when the buckets are stacked. The outer barrel 7 has a circumferentially arranged array of fixing buckles 11 integrally injection molded on its peripheral wall. The buckles 9 are located between adjacent fixing buckles 11. The top of the outer barrel 1 has a protruding strip 12 integrally injection molded. The fixing buckles 11 and the protruding strip 12 are interlocked with each other. The barrel lid 7 has a limiting strip 13 integrally injection molded to restrict the displacement of the fixing buckles 11, so that the barrel lid 7 is fixedly connected to the outer barrel 1. The limiting strip 13 is stamped with a tear line 15. The limiting strip 13 can be separated from the fixing buckles 11 by tearing the strip 15. At this time, the fixing buckles 11 can be flipped outward to disengage from the protruding strip 12, thereby opening the barrel lid 7.

[0017] Working principle: When several barrels are stacked, the outer ring 4 of the upper barrel engages with the groove 8 of the lower barrel. The liquid outlet and end cap 14 are located in the receiving cavity 6. By flipping the turning mark 16, the buckle 9 is flipped upward and engages with the through groove 10. At this time, the displacement of the upper barrel relative to the lower barrel is restricted. When the barrel is subjected to external force, the buffer cavity 3 reduces the force on the inner barrel 2. The gradually increasing thickness of the inner barrel 2 wall from top to bottom makes the center of gravity lower, increasing the pressure resistance and stability of the bottom of the inner barrel 2. After removing the limiting strip 13 by tearing the tear mark 15, the fixing buckle 11 can be flipped to disengage it from the protrusion 12. At this time, the barrel cap 7 can be removed.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
