Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular, to a reliable plastic packaging container. Background Technology

[0002] Plastic packaging containers are used in the food, chemical, and pharmaceutical industries. With the rapid rise of the plastics industry, plastic packaging containers have replaced traditional materials such as metal, plastic sheets, ceramics, and wood in many aspects and have become widely used. Plastic packaging containers generally consist of a body and a lid. Currently, the most common connection between the body and lid is a snap-fit ​​connection. In actual use, when the user manually lifts the handle on the lid, the lid can easily detach from the body due to the weight of the contents. Furthermore, because of the single snap-fit ​​connection, children can easily open the lid after coming into contact with such packaging containers, thus accessing the contents and posing a safety hazard.

[0003] Therefore, the inventors designed a reliable plastic packaging container that prevents the lid from easily coming off and also prevents children from easily opening the lid. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, the connection between the lid and the body is not reliable and there is a possibility that children may accidentally open it, which poses a safety hazard. In view of this, this utility model provides a plastic packaging container with good connection reliability and which is not easy for children to open.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a reliable plastic packaging container, including a body and a cover detachably covering the opening end of the body. The top of the outer wall of the body is provided with a plurality of stop blocks protruding outward, and the space between each two adjacent stop blocks forms a through groove. The edge of the cover is provided with a plurality of extensions protruding downward, and the lower end of the extension is provided with a retaining block protruding inward. The cover can be moved axially so that the retaining block passes through the through groove. After the cover is rotated, the retaining block moves to directly below the stop block. The side wall of the body is provided with a flange below the stop block. The part of the cover located between two adjacent extensions is provided with a locking tongue, and the locking tongue engages with the flange.

[0006] Furthermore, the cover is coaxially arranged with the body, the outer surface of the stop block is an arc-shaped structure, the extension is an arc-shaped plate structure, and the inner wall of the extension can fit against the arc-shaped structure on the stop block.

[0007] Furthermore, the inner surface of the abutment block has an arc-shaped structure, and the arc-shaped structure of the abutment block is in contact with the outer surface of the body.

[0008] Furthermore, the reliable plastic packaging container also includes a seal that is pressed between the upper surface of the body and the lower surface of the cover.

[0009] Furthermore, a mounting groove is provided circumferentially on the upper surface of the body, and the sealing element is installed in the mounting groove.

[0010] Furthermore, the lower end of the flange forms a buckle, the upper end of the latch is connected to the cover, and the inner side of the lower end of the latch forms a groove, with the buckle and the groove engaging with each other.

[0011] Furthermore, the end of the latch that connects to the cover is thinner than the end that has the slot.

[0012] Furthermore, an operating part is formed on the locking tongue extending downward below the slot, and the inner wall of the operating part is provided with a slope.

[0013] Furthermore, limit blocks are provided on both sides of the latch on the flange, and the limit blocks are in contact with the opposite sides of the latch.

[0014] The beneficial effects of this utility model are: the reliable plastic packaging container of this utility model relies on the supporting action between the supporting block and the stop block and the locking action between the locking tongue and the flange to achieve double locking between the body and the lid, effectively preventing the lid from detaching from the body. At the same time, the method of opening the lid by first rotating and then moving the lid is relatively difficult for children, effectively preventing children from accidentally opening the lid, eliminating safety hazards, and making it more reliable to use.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figures 1-5 This utility model provides a reliable plastic packaging container, including a body 1 and a cover 2. The upper end of the body 1 is open. The cover 2 is detachably placed on the open end of the body 1. The top of the outer wall of the body 1 is provided with a plurality of spaced stop blocks 11. The space between each two adjacent stop blocks 11 forms a through groove 12. The edge of the cover 2 is provided with a plurality of downward protruding extensions 21. The lower end of the extension 21 is provided with an inward protruding abutment block 22. The cover 2 can be moved axially so that the abutment block 22 passes through the through groove 12. After the cover 2 is rotated, the abutment block 22 moves to the position directly below the stop block 11. The side wall of the body 1 is provided with a flange 13 below the stop block 11. The part of the cover 2 located between two adjacent extensions 21 is provided with a rotatable locking tongue 23, which engages with the flange 13.

[0024] This utility model provides a reliable plastic packaging container. When the lid 2 is connected to the body 1, the lid 2 is first moved axially relative to the body 1, allowing the abutment block 22 to pass through the through groove 12. At this time, the abutment block 22 and the stop block 11 are offset from each other. Then, the lid 2 is rotated relative to the body 1, causing the abutment block 22 to move directly below the stop block 11. At this time, the abutment block 22 and the stop block 11 are positioned opposite each other. Under the obstruction of the stop block 11, the lid 2 cannot move axially away from the body 1. At this point, the lid 2 and the body 1 are initially fixed. Next, by flipping the locking tongue 23, the bottom of the locking tongue 23 is engaged with the flange 13, thereby achieving secondary fixation. In this way, through the double locking action, the lid 2 is effectively prevented from detaching from the body 1.

[0025] In addition, when it is necessary to open the cover 2, the locking tongue 23 must first be flipped to release the locking relationship between the locking tongue 23 and the flange 13. Then, the cover 2 is rotated relative to the body 1 to displace the abutment block 22 and the stop block 11, thereby releasing the lock between the abutment block 22 and the stop block 11. Finally, the abutment block 22 is moved along the through groove 12 to remove the cover 2 from the body 1. The above operation of opening the cover 2 is relatively difficult for children, effectively preventing children from accidentally opening the cover and eliminating safety hazards.

[0026] Please see Figure 2 In this embodiment, the cover 2 is coaxially arranged with the main body 1. The outer surface of the stop block 11 is an arc-shaped structure, and the center of the arc-shaped structure on the stop block 11 is located on the central axis of the main body 1. The extension 21 is an arc-shaped plate structure, and the inner wall of the extension 21 matches the arc-shaped structure on the stop block 11. When the abutment block 22 passes through the through groove 12 and the cover 2 is rotated, the inner wall of the extension 21 can fit against the arc-shaped structure of the stop block 11, thereby limiting the position of the cover 2 in the radial direction.

[0027] Meanwhile, the inner surface of the abutment block 22 has an arc-shaped structure, and the arc-shaped structure of the abutment block 22 matches the outer surface of the body 1. Thus, when the abutment block 22 moves in the through groove 12, the arc-shaped structure of the abutment block 22 fits against the outer surface of the body 1, improving the stability of the cover 2.

[0028] The reliable plastic packaging container of this utility model also includes a sealing element 3. The sealing element 3 is pressed between the upper end face of the body 1 and the lower surface of the cover 2 to improve the reliability of the cover 2 sealing the opening end of the body 1. When installing the cover 2, the cover 2 needs to be pressed down to compress the sealing element 3 before the abutment block 22 can be moved below the stop block 11. Then, by rotating the cover 2, the abutment block 22 is moved directly below the stop block 11. At this time, the pressing action on the cover 2 is released, the sealing element 3 is reset, and the upper surface of the abutment block 22 is tightly pressed against the lower surface of the stop block 11, thereby increasing the axial upward force between the abutment block 22 and the stop block 11, improving the connection strength between the abutment block 22 and the stop block 11, and preventing the cover 2 from being easily rotated.

[0029] In a preferred embodiment, a mounting groove 14 is provided circumferentially on the upper surface of the body 1, and the seal 3 is installed in the mounting groove 14. It is understood that in other embodiments, the mounting groove for installing the seal 3 may also be provided on the lower surface of the cover 2, and this is not limited here. The seal 3 is made of silicone or rubber material, and this is not limited here.

[0030] Please see Figure 4 , Figure 5In this embodiment, the flange 13 has a ring-shaped structure and is coaxially arranged with the body 1. The ring-shaped flange 13 enhances the structural strength of the opening at the upper end of the body 1, preventing the opening of the body 1 from easily deforming. The lower end of the flange 13 forms a buckle 131, the upper end of the latch 23 is connected to the cover 1, and the inner side of the lower end of the latch 23 forms a groove 231. The buckle 131 and the groove 231 engage with each other. Since both the flange 13 and the latch 23 are deformable plastic parts, the user can connect and separate the buckle 131 and the groove 231 when rotating the latch 23.

[0031] In a preferred embodiment, the end of the latch 23 that is connected to the cover 2 is thinner than the end that has the slot 231. This reduces the structural strength of the part of the latch 23 that is connected to the cover 2. Therefore, when the thinner end of the latch 23 is connected to the cover 2, it is easier for the latch 23 to be flipped, which is beneficial for user operation.

[0032] Furthermore, an operating part 232 extends downward from below the slot 231 on the latch 23. The inner wall of the operating part 232 is provided with a slope 233. The slope 233 is provided so that the user can insert his / her finger into the inside of the operating part 232, thereby making it easier for the user to pry the latch 23 outward to flip the latch 23, thereby disengaging the buckle 131 from the slot 231.

[0033] In a preferred embodiment, limit blocks 132 are provided on both sides of the latch 23 on the flange 13. The limit blocks 132 are in contact with the opposite sides of the latch 23. In this way, the limit blocks 132 limit the latch 23 and prevent the cover 2 from driving the latch 23 to rotate circumferentially.

[0034] In this embodiment, a retaining ring 4 protrudes outward from the bottom of the main body 1. When closing and opening the cover 2, the user can fix the main body 1 by using the retaining ring 4, for example, by stepping on the retaining ring 4, to facilitate operation of the cover. In addition, a handle (not shown) is installed on the cover 2 for the user to grip, so as to facilitate the user to move the packaging container.

[0035] This utility model provides a reliable plastic packaging container. By relying on the supporting action between the supporting block 22 and the stop block 11, and the locking action between the locking tongue 23 and the flange 13, a double locking between the main body 1 and the cover 2 is achieved, effectively preventing the cover 2 from detaching from the main body 1. At the same time, the method of opening the cover by first rotating and then moving the cover 2 is relatively difficult for children, effectively preventing children from accidentally opening the cover, eliminating safety hazards, and making it more reliable to use.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
