Description

Technical Field

[0001] This utility model belongs to the field of container technology, specifically relating to a container for holding bagged items. Background Technology

[0002] Packaging barrels are a general term in the packaging industry that refers to all kinds of barrel containers, mainly used for holding bagged powdery or liquid products. They can be classified into types such as plastic, metal, and paper composite according to the material.

[0003] When existing packaging containers contain bagged powders or liquids, the plastic bag adheres tightly to the inner wall of the container. This creates negative pressure between the container's inner wall and the plastic bag during the process of removing the contents, making it difficult for workers to retrieve the items and significantly reducing the practicality of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a convenient container for retrieving items.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a container for holding bagged items, the container including a container body with an opening at the top and a cover covering the top of the container body, the outer side of the bottom of the container body having an upwardly recessed sliding groove extending in the horizontal direction, and an air inlet hole communicating with the interior of the container body being provided on the bottom wall of the sliding groove.

[0006] The container also includes a valve mechanism that is slidably disposed in the sliding groove. The valve mechanism has working states of opening the air inlet and closing the air inlet. When the valve mechanism is in the working state of opening the air inlet, gas outside the container body can enter the container body through the air inlet.

[0007] As a further description of the above technical solution:

[0008] The air valve mechanism includes a sliding block slidably disposed in the sliding groove and a connecting hole formed on the sliding block and passing through the upper and lower sides of the sliding block. When the air valve mechanism is in the working state of opening the air inlet, the connecting hole communicates with the air inlet; when the air valve mechanism is in the working state of closing the air inlet, the upper surface of the sliding block abuts against the air inlet to close the air inlet.

[0009] As a further description of the above technical solution:

[0010] The container also includes an operating mechanism for switching the air valve mechanism between two operating states: opening the air inlet and closing the air inlet.

[0011] As a further description of the above technical solution:

[0012] The operating mechanism includes a rotating rod inserted horizontally at the bottom of the container body. The rotating rod is rotatable about its own axis. One end of the rotating rod is inserted into the sliding block and threadedly connected to the sliding block. The other end of the rotating rod is exposed outside the container body. The rotation of the rotating rod drives the sliding block to slide horizontally in the sliding groove. The operating mechanism also includes a drive unit for driving the rotating rod to rotate.

[0013] As a further description of the above technical solution:

[0014] The sliding block has a movable groove extending along the length of the rotating rod at the position corresponding to the position of the rotating rod. The inner wall of the movable groove is provided with an internal thread, and one end of the rotating rod has an external thread that can cooperate with the internal thread.

[0015] As a further description of the above technical solution:

[0016] The driving unit includes a connecting rod 1 with one end fixedly sleeved on the other end of the rotating rod and a connecting rod 2 rotatably connected to the other end of the connecting rod 1. An external force operates the connecting rod 2 to drive the rotating rod to rotate around its own axis, thereby driving the sliding block to slide.

[0017] As a further description of the above technical solution:

[0018] A torsion spring is provided on the outer contour of the rotating shaft. The two ends of the torsion spring are connected to the inner wall of the groove near the top. The first connecting rod extends in the vertical direction. A groove is formed on the outer side of the first connecting rod along its length. The groove is used to accommodate the second connecting rod. The second connecting rod is rotatably connected to the first connecting rod through a rotating shaft provided in the groove and extending in the horizontal direction. A torsion spring is provided between the second connecting rod and the groove wall. The torsion spring is used to accommodate the second connecting rod in the groove.

[0019] As a further description of the above technical solution:

[0020] The outer surface of the second connecting rod has anti-slip texture.

[0021] As a further description of the above technical solution:

[0022] The outer surface of the upper end of the container body has an external thread, and the cover has an internal thread that mates with the external thread.

[0023] As a further description of the above technical solution:

[0024] The container is a can, barrel, or box, and the box includes a top and bottom lid box.

[0025] This utility model has the following beneficial effects:

[0026] Compared with existing technologies, this container has an air valve mechanism at the bottom of the container body. When the staff takes out the contents of the container, the blocked air inlet is opened, allowing outside air to enter the gap between the container body and the plastic bag. This dynamically balances the internal and external air pressure of the container body when the staff takes out the contents, making it easier for the staff to take out the contents of the container body and increasing the practicality of the equipment.

[0027] Compared with existing technologies, this container, through its operating mechanism, allows workers to easily move the sliding block within the sliding groove, aligning the air inlet through the sliding groove with the connection hole on the sliding block. This facilitates the use of the equipment and further reduces the difficulty of operation. Attached Figure Description

[0035] 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.

[0036] Reference Figure 1-5 The present invention provides a container, comprising a container body 1 with an opening at the top and a cover 2 covering the top of the container body 1. The outer side of the bottom of the container body 1 has an upwardly recessed sliding groove 3 extending in the horizontal direction. The bottom wall of the sliding groove 3 has an air inlet 4 communicating with the interior of the container body 1. The container also includes a valve mechanism slidably disposed in the sliding groove 3. The valve mechanism has working states of opening the air inlet 4 and closing the air inlet 4. When the valve mechanism is in the working state of opening the air inlet 4, gas outside the container body 1 can enter the interior of the container body 1 through the air inlet 4. The outer side of the upper end of the container body 1 has an external thread 2, and the cover 2 has an internal thread 2 that mates with the external thread 2.

[0037] In use, powdered or liquid products packaged in plastic bags are placed inside the container body 1. The lid 2 is then sealed to the container body 1 via a threaded connection, preventing the contents from getting damp, leaking, or being contaminated by the outside. When it is necessary to remove the contents from the container body 1, the operator opens the lid 2 and then activates the air valve mechanism, causing the sliding block 5 to move within the sliding groove 3, thereby opening the air inlet 4. This allows outside air to enter the gap between the container body 1 and the plastic bag, enabling air circulation between the inside and outside of the container body 1. This allows for dynamic balance of air pressure inside and outside the container body 1 when the operator retrieves the contents, making it easier for the operator to remove the contents from the container body 1 and increasing the practicality of the equipment. After the contents are removed, the air inlet 4 is closed to maintain a sealed state, fundamentally solving the problem of difficulty in retrieving contents caused by negative pressure when using existing containers.

[0038] The air valve mechanism includes a sliding block 5 slidably disposed within a sliding groove 3 and a connecting hole 12 formed on the sliding block 5 and extending through its upper and lower sides. When the air valve mechanism is in the working state of opening the air inlet 4, the connecting hole 12 communicates with the air inlet 4; when the air valve mechanism is in the working state of closing the air inlet 4, the upper surface of the sliding block 5 abuts against the air inlet 4 to close the air inlet 4. The container also includes an operating mechanism for switching the air valve mechanism between the two working states of opening and closing the air inlet 4. The operating mechanism includes a rotating mechanism inserted horizontally into the bottom of the container body 1. The rotating rod 6 can rotate around its own axis. One end of the rotating rod 6 is inserted into the sliding block 5 and threadedly connected to the sliding block 5. The other end of the rotating rod 6 is exposed outside the container body 1. The rotation of the rotating rod 6 drives the sliding block 5 to slide horizontally in the sliding groove 3. The operating mechanism also includes a drive unit 8 for driving the rotating rod 6 to rotate. The sliding block 5 has a movable groove 9 extending along the length direction of the rotating rod 6 at the position corresponding to the position of the rotating rod 6. The inner wall of the movable groove 9 is provided with an internal thread 10. One end of the rotating rod 6 has an external thread 11 that can cooperate with the internal thread 10.

[0039] Optionally, the two ends of the sliding block 5 adopt an arc transition, and the two ends of the sliding groove 3 also adopt an arc transition.

[0040] When it is necessary to remove the contents from the container body 1, the operator uses the drive unit 8 to rotate the rotating rod 6 around its own axis, causing the sliding block 5 to slide within the sliding groove 3. When the sliding block 5 moves to the end of the sliding groove 3, the operator can stop using the drive unit 8, and the connecting hole 12 on the sliding block 5 is aligned with the air inlet 4. At this time, outside air enters the gap between the container body 1 and the plastic bag, thereby allowing air circulation between the inside and outside of the container body 1. This also allows the operator to dynamically balance the air pressure inside and outside the container body 1 when retrieving the contents, making it easier for the operator to remove the contents from the container body 1. This greatly increases the practicality of the container. Furthermore, the curved transition at the end restricts the rotational freedom of the sliding block 5 within the sliding groove 3, preventing circumferential offset of the sliding block 5 that could cause the connecting hole 12 and the air inlet 4 to misalign. At the same time, the curved transition structure at the end reduces the jamming phenomenon during the sliding process compared to the square structure, ensuring smooth movement of the sliding block 5 and improving the working reliability and service life of the air valve mechanism.

[0041] The drive unit includes a connecting rod 13 fixed at one end and the other end of the rotating rod 6, and a connecting rod 2 15 rotatably connected to the other end of the connecting rod 13. External force operates the connecting rod 2 15 to drive the rotating rod 6 to rotate around its own axis, thereby driving the sliding block 5 to slide.

[0042] See Figure 4 and Figure 5 The first connecting rod 13 extends in the vertical direction, and a groove 14 is formed on the outer side of the first connecting rod 13 along its length direction. The groove 14 is used to receive the second connecting rod 15. The second connecting rod 15 is rotatably connected to the first connecting rod 13 through a rotating shaft 18 that is set in the groove 14 and extends in the horizontal direction. A torsion spring 19 is provided between the second connecting rod 15 and the groove wall of the groove 14. The torsion spring 19 is used to receive the second connecting rod 15 in the groove 14.

[0043] When the operator needs to use the operating mechanism, the operator first rotates the connecting rod 15, which is housed in the groove 14, out of the groove 14, so that the connecting rod 15, the connecting rod 13, and the rotating rod 6 form a Z-shape, making the operating mechanism more ergonomic and making it more convenient and comfortable for the operator to rotate the connecting rod 15. After use, the connecting rod 15 is then inserted back into the groove 14 by the torsion spring 19, so that the connecting rod 15 is always kept in the groove 14, avoiding the problem that the connecting rod 15 is easy to fall off due to shaking during the transportation of the container body 1. The outer surface of the connecting rod 15 has anti-slip texture 16.

[0044] When the staff holds the connecting rod 2 15, the anti-slip texture 16 is used to increase the anti-slip effect of the connecting rod 2 15 during use.

[0045] Working principle: When the container is in use, the powdered or liquid product packaged in a plastic bag is placed in the container body 1, and the lid 2 is used to achieve a sealed fit with the container body 1 through a threaded connection to prevent the contents from getting damp, leaking or being contaminated by the outside. When it is necessary to remove the contents from the container body 1, the staff opens the lid 2.

[0046] Subsequently, the staff rotated the connecting rod 15, which was engaged in the groove 14, out of the groove 14, so that the connecting rod 15, the connecting rod 13, and the rotating rod 6 formed a Z-shape. Rotating the connecting rod 15 drove the rotating rod 6 to rotate around its own axis, thereby causing the sliding block 5 to slide in the sliding groove 3. When the sliding block 5 moved to the end of the sliding groove 3, the staff no longer needed to use the operating mechanism. This also aligned the connecting hole 12 on the sliding block 5 with the air inlet 4. At this time, outside air entered the gap between the container body 1 and the plastic bag through the connecting hole 12 and the air inlet 4, allowing air to circulate inside and outside the container body 1. This enabled the staff to dynamically balance the air pressure inside and outside the container body 1 when retrieving items, making it easier for the staff to remove the contained items from the container body 1.

[0047] Finally, the staff rotates the connecting rod 2 5 in the opposite direction, causing the sliding block 5 to slide in the opposite direction. The upper surface of the sliding block 5 abuts against the air inlet 4, and the connecting hole 12 is no longer aligned with the air inlet 4, thus completing the sealing of the air inlet 4 and keeping the air inlet 4 in a sealed state. After the connecting rod 2 15 is used, it can be snapped into the groove 14.

[0048] This container can fundamentally solve the problem of difficulty in retrieving items caused by negative pressure when using existing containers.

[0049] In other embodiments, the container body and lid may not have threaded connections, such as a top and bottom lid box.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
