Description

container

Technical Field

The invention relates to a container, and more particularly to a container with a hidden sliding door.

Background Art

Common containers on the market include plastic, wood, paper, steel, and a combination of plastic and steel. Among them, plastic containers are increasingly used in various industries such as warehousing, logistics, packaging, and retail displays, because they are recyclable, moisture-resistant, and have a long lifespan, and are gradually being promoted as a substitute for wooden and paper containers.

Take plastic containers as an example. Most of these containers have a base and two sets of opposite side panels. In order to facilitate loading and unloading of goods, the initial conventional design is: a small door that can be rotated downward to open is provided on the top of the side panel of the container to facilitate loading and unloading of goods; there is also a container on the market with a small door at the bottom of the side panel, such as patent: CN201910619482.1. After rotating the small door upward to open it, the container can be tilted so that the goods can be quickly unloaded through the small door at the bottom of the side panel. The effect of this is to achieve rapid unloading of goods and improve work efficiency.

However, with the increasing use of plastic containers, the increasing diversification of the goods loaded, and the continuous updating of market demand, such small doors that rotate to open or close can no longer fully meet the ever-changing market. For example, the market requires that the goods in the container be directly unloaded into a fixed channel and directly transported to the processing workshop through the fixed channel. If a small door that rotates downward from the top of the side panel is used, direct unloading cannot be achieved; if a small door that rotates upward from the bottom of the side panel is used, although the goods can be unloaded by tilting the container, due to the structural characteristics of such a small door that rotates to open, the small door requires a certain radial space at the beginning, and after the small door rotates upward, there is a gap of the thickness of the side panel between the entire container and the fixed channel. This results in the goods in the container being directly dumped out during the process of the small door rotating upward, and after the small door is opened, the container needs to be moved to align with the fixed channel, and the goods will be scattered during unloading due to the gap between the container and the fixed channel. The whole process is very cumbersome, and the poor unloading effect can easily cause secondary contamination of the goods.

In summary, with the continuous update of market demand, it is necessary to meet the diversified cargo loading and unloading needs. Therefore, the art needs a container that does not increase radial space during the entire process from closing to opening the small door of the container, does not protrude from the side panel after opening, and does not increase the length and width of the container.

Referring to FIG. 1 , a perspective view of a container 100 according to an embodiment of the present invention is shown. The container 100 includes: a base 1 and two pairs of side panels 2 and 3 extending upward from the four sides of the base 1. An opening 301 is provided on one of the side panels 3 (see FIG. 7 ). A sliding door 4 is provided on the side panel 3, and the sliding door 4 is arranged within the thickness of the side panel 3 and can slide relative to the side panel 3 between a position covering the opening 301 ( FIG. 1 ) and a position exposing the opening 301 ( FIG. 2 ). Although the figure shows that the opening 301 and the sliding door 4 are provided on the proximal side panel 3, it should be understood that the opening and the sliding door can be provided on any one or more of the two pairs of side panels. In the illustrated embodiment, the opening 301 and the sliding door 4 are both rectangular in shape. However, it should be understood that the shapes of the opening 301 and the sliding door 4 can be set to any suitable shape as required. Using a sliding door 4 set within the thickness of the side panel 3 to open and close the opening 301 can hide the sliding door 4 without occupying excess thickness or radial space. It can be applicable to various types of containers and is also applicable to the case where the side panels 2 and 3 can be folded relative to the base 1.

In the preferred embodiment shown in FIG. 1 , the opening 301 is located at the lower half of the side panel 3, more specifically at the bottom of the side panel 3. This arrangement of the opening 301 facilitates the unloading of the goods in the container 100, especially for flowable bulk solids, such as soybeans, etc., which can be quickly unloaded through the opening 301. However, it should be understood that the opening 301 can be located at any position of the side panel 3 without departing from the scope of the present invention.

A slide rail 303 (see FIG. 7 ) is provided on the side plate 3, and the sliding door 4 slides along the slide rail 303 between the closed position and the open position. In the illustrated embodiment, the slide rail 303 is provided on both sides of the sliding door 4. Specifically, in the illustrated embodiment, the slide rail 303 is an elongated slide groove provided on both sides of the opening 301 on the side plate 3, and the two side edges of the sliding door 4 are accommodated in the elongated slide groove and slide up and down therein. However, it should be understood that the slide rail 303 can also be provided in other forms, for example, a card slot can be provided on both sides of the sliding door 4, and a vertical guide piece can be provided on both sides of the opening 301, so that the card slot can be sleeved on the guide piece to guide the sliding door 4 to slide up and down.

In order to facilitate the sliding operation of the sliding door 4, a pull rod 5 extending upward may be provided at the top of the sliding door 4 (as shown in the embodiment in FIG. 1-10), or the height of the sliding door 4 may be higher than the height of the opening 301 (as shown in FIG. 11-18). In the embodiment shown in FIG. 1-10, a pull ring is provided at the top of the pull rod 5, while in the embodiment shown in FIG. 11-18, a pull ring is provided at the top of the sliding door 4, so that the sliding door 4 can be slid by the pull ring.

In addition, in order to position the sliding door 4 at the closed position and the open position and prevent the sliding door 4 from accidentally sliding from the closed or open position to the open or closed position, a closing positioning mechanism and an opening positioning mechanism are provided on the sliding door.

The closing positioning mechanism and the opening positioning mechanism of the first embodiment are now described in conjunction with Figures 1 to 10. In this embodiment, a pull rod 5 extending upward is provided at the top of the sliding door 4. In the illustrated embodiment, the pull rod 5 can be detachably connected to the sliding door 4, but it should be understood that the two can also be formed integrally.

As shown in FIG1 , in the closed position, the pull rod 5 extends upward from the top of the sliding door 4 to the top of the side panel 3, and a handle 508 may be provided on the top of the pull rod 5, so that the operator can drive the small door 4 to slide up and down by pulling the handle 508 on the pull rod 5, thereby completing the opening and closing of the small door. As shown in FIGS. 1-4 and 7 , above the opening 301, the side panel 3 is provided with a sliding door accommodating cavity 302 on the outer surface. Although the sliding door accommodating cavity 302 and the slide rail 303 are provided on the outer surface of the side panel 3 in the illustrated embodiment, it should be understood that they may also be provided on the inner surface of the side panel 3. The slide rail 303 is provided on both sides of the opening 301 and the sliding door accommodating cavity 302 on the outer surface of the side panel 3, so that when the sliding door 4 is in the closed position, it is located between the slide rails 303 and covers the position of the opening 301; and when the sliding door 4 is in the open position, it is located in the sliding door accommodating cavity 302. The sliding door 4 can freely switch between the open position and the closed position along the sliding rail 303. During the sliding process of the sliding door 4, whether it is in the sliding door accommodating cavity 302 or in the position covering the opening 301, it does not protrude from the outer surface of the side plate 3, so the sliding door 4 is always hidden in the side plate 3 and does not occupy extra thickness space.

In addition, a pull rod groove 304 is provided on the outer surface of the side plate 3, and the pull rod groove 304 penetrates the top of the side plate 3 and the sliding door accommodating chamber 302. Therefore, when the sliding door 4 slides up and down and switches between the open position and the closed position, the pull rod 5 slides up and down together with the sliding door 4 in the pull rod groove 304. Specifically, in the illustrated embodiment, the pull rod groove 304 is located above the sliding door accommodating chamber 302, and is formed by two sections of vertical through grooves 3041 and 3042 on the outer surface of the side plate 3 that are vertically aligned and spaced apart from each other. The through groove 3041 is above the through groove 3042. However, it should be understood that the pull rod groove 304 can also be formed by more than two sections of vertical through grooves that are vertically aligned and spaced apart from each other, or the pull rod groove 304 is formed by one section of vertical through groove. Specifically, in the illustrated embodiment, specifically see FIG. 7, the through groove 3041 is formed by the stopper accommodating chamber 307 and the stopper 6 that are locked with each other. As shown in FIG7 , a block accommodating cavity 307 is provided on the outer surface of the side plate 3, and a clamping hole 307a is provided on both sides of the block accommodating cavity 307. Meanwhile, as shown in FIG10 , the block 6 includes a baffle 603 and side walls 601 extending perpendicularly to the baffle on both sides of the baffle. Hanging platforms 602 are provided on the two side walls 601. Thus, when the block 6 is placed in the block accommodating cavity 307 on the side plate 3, the hanging platforms 602 on the block 6 are respectively clamped into the clamping holes 307a on the side plate 3. A through groove 3041 is formed between the block accommodating cavity 307 and the block 6, so as to ensure that the pull rod 5 slides up and down in the through groove 3041 without being separated from the side plate 3. In the illustrated embodiment, the structure of the through groove 3042 is the same as that of the through groove 3041. However, it should be understood that the structures of the two may also be different, and the through groove 3041 and/or the through groove 3042 may also be formed as an integrated through groove on the outer surface of the side plate 3 without the block 6. In order to allow the pull rod 5 to slide smoothly in the through grooves 3041 and 3042, there is a certain gap between the pull rod 5 and the through grooves 3041 and 3042.

In addition, a limiting boss 305 extending outward from the side of the block accommodating cavity 307 opposite to the block 6 is provided at the bottom of the through groove 3042. At the same time, as shown in Figures 6 and 9: a biasing device is provided on the pull rod 5, and the biasing device biases the pull rod 5 toward the side plate 3. In the illustrated embodiment, the biasing device is an elastic arm 501 provided on the pull rod 5. A limiting portion 502 protruding from the pull rod 5 toward the side plate 3 is provided at the extension section of the pull rod 5 close to the elastic arm 501, wherein when the sliding door 4 moves to the open position, the elastic arm 501 as the biasing device and the limiting portion 502 are in a position corresponding to the through groove 3042. When the pull rod 5 is biased toward the side plate 3, the limiting portion 502 can be hooked on the limiting boss 305, thereby preventing the pull rod 5 from sliding downward together with the sliding door 4. The limiting portion 502 and the limiting boss 305 together constitute the opening positioning mechanism of the sliding door 4. In addition, in order to facilitate the unlocking of the opening positioning mechanism and facilitate the disengagement of the limiting portion 502 from the limiting boss 305 so that the pull rod and the sliding door 4 can slide downward, a guide portion 502a can be further provided below the limiting portion 502, and the guide portion 502a is an inclined surface that is inclined downward from the farthest protruding position of the limiting portion 502 and toward the pull rod 5. In the illustrated embodiment, the limiting portion 502 is located on the elastic arm 501, but it should be understood that the limiting portion 502 can also be directly provided on the pull rod 5 itself. In the illustrated embodiment, the elastic arm 501 is formed integrally with the pull rod 5, but it should be understood that the elastic arm 501 can also be formed separately and fixed to the pull rod 5. It should also be understood that the elastic arm 501 can be replaced by other elastic structures such as springs, elastic foam blocks, etc. to serve as a biasing device, or the extension section of the pull rod 5 itself has elasticity.

Due to the opening positioning mechanism, when the sliding door 4 is pulled upward to the open position by the pull rod 52, the limiting portion 502 is hooked on the limiting boss 305, thereby keeping the sliding door 4 in the open state to prevent it from accidentally falling. When the sliding door 4 needs to be closed, it is only necessary to overcome the biasing force of the biasing device to deflect the pull rod 5 outward and press it down, and the limiting portion 502 will be disengaged from the limiting boss 305 due to the guidance of the guide portion 502a, so that the sliding door 4 slides down along the guide rail 303 to the closed position. In the illustrated embodiment, the limiting portion 502 is located on the elastic arm 501, so that when the sliding door 4 needs to be closed, it is only necessary to press the pull rod 5 downward to cause the elastic arm 501 to elastically deform, and the limiting portion 502 passes over the limiting boss 305 and slides downward under the guidance of the guide portion 502a.

In addition, as shown in FIGS. 5 and 9 , the pull rod 5 is further provided with a locking boss 503 protruding from the pull rod 5 toward the side plate 3. As shown in FIGS. 5 and 7 , the side plate 3 is provided with a locking portion 306 extending toward the pull rod 5, and the locking portion 306 is located at a position corresponding to the through groove 3041. When the sliding door 4 is in the closed position, the locking boss 503 is located below the locking portion 306. The locking boss 503 and the locking portion 306 constitute a closed positioning mechanism. The interaction between the two keeps the sliding door 4 in the closed position to prevent it from being accidentally opened. Preferably, when the sliding door 4 is in the closed position, the locking boss 503 is located at a position corresponding to the through groove 3041. It is also preferably provided at this position with a biasing device for biasing the pull rod 5 toward the side plate 3, thereby ensuring that the locking boss 503 and the locking portion 306 interact to position the sliding door 4 in the closed position. In the illustrated embodiment, the biasing device is an elastic arm 504. However, it should be understood that the biasing device may also be other devices such as a spring or an elastic foam block, or the extension section of the pull rod 5 itself is elastic. In addition, another guide portion 503a may be provided below the locking boss 503, and the other guide portion 503a is an inclined surface extending downward from the locking boss 503 and toward the pull rod 5. The provision of the guide portion 503a makes it easier for the locking boss 503 to slide over the locking portion 306. When opening the sliding door 4, as shown in FIG5 , it is necessary to first overcome the biasing force of the biasing device and pull the pull rod 5 outward so that the locking boss 503 is separated from the locking portion 306, and then pull it upward to complete the opening of the sliding door 4.

In the above embodiment, the through slot 3042 and the opening positioning mechanism are disposed below the through slot 3041 and the closing positioning mechanism, but it should be understood that the positions of the two may be interchanged without departing from the scope of the present invention.

In addition, as shown in FIG8 , a boss 401 extending upward is provided at the top of the sliding door 4, an open portion 402 is provided in the middle of the boss 401, the open portion 402 is opened upward and inward, and a hanging platform 403 is provided on both sides of the open portion 402. Concave cavities are provided on the surfaces of the two hanging platforms 403 facing each other. At the same time, as shown in FIG9 , extension arms 505 extending downward are provided on both sides of the bottom of the pull rod 5, and hooks 505a extending laterally to both sides are provided at the ends of the extension arms 505. Thus, as shown in FIG3 , the bottom extension section of the pull rod 5 is located in the open portion 402 of the boss 401 at the top of the sliding door 4, and the hook 505a on the pull rod 5 is inserted into the concave cavity of the hanging platform 403 at the top of the sliding door 4, so as to realize the connection between the pull rod 5 and the sliding door 4, and ensure that the pull rod 5 and the sliding door 4 will not be separated during the overall upward and downward sliding process. The connection structure between the sliding door 4 and the rod 5 allows the rod 5 to be easily removed from the sliding door 4 and achieves a firm connection between the two. However, it should be understood that the rod 5 and the sliding door 4 can be fixedly connected to each other in any suitable manner without departing from the scope of the present invention.

This sliding door opening method is novel, the structure is simple and reliable, and the sliding door does not need to occupy excess side panel thickness space during the opening and closing process. The operation is simple, fast and more concealed.

Figures 11 to 18 are another embodiment according to the present invention. As shown in Figure 11, compared with the first embodiment, the pull rod 5 and the stopper 6 are eliminated in this embodiment, and the sliding door 4 integrally passes through the side plate 3 and can slide up and down in the side plate 3. In the illustrated embodiment, a handle 408 is provided at the top of the sliding door 4, so that the sliding door 4 can slide up and down by pulling the handle 408.

As shown in FIG. 17 , a sliding door accommodating cavity 302’ is provided on one surface of the side panel 3. In the illustrated embodiment, the sliding door accommodating cavity 302’ is provided on the inner surface of the side panel 3, but it should be understood that the sliding door accommodating cavity 302’ may also be provided on the outer surface of the side panel 3. Guide rails 303’ are provided on both sides of the sliding door accommodating cavity 302’. In order to facilitate the smooth sliding of the sliding door 4 in the guide rails 303’, there is a certain gap between the two. A locking cavity 306’ and a limiting cavity 305’ are also provided on the surface of the side panel 3 inside the sliding door accommodating cavity 302’. A locking boss 403 and a limiting hook 402 protruding from the surface are provided on the surface of the sliding door 4 opposite to the sliding door accommodating cavity 302’. The limit hook 402 and the limit cavity 305' constitute an opening positioning mechanism, so that when the sliding door 4 slides upward to the open position, the limit hook 402 can be located in the limit cavity 305' and abut against the bottom wall of the limit cavity 305', thereby preventing the sliding door 4 from sliding downward and accidentally closing. The locking boss 403 and the locking cavity 306' constitute a closing positioning mechanism, so that when the sliding door 4 slides downward to the closed position, the locking boss 403 is located in the locking cavity 306' and abuts against the top wall of the locking cavity 306', thereby positioning the sliding door 4 in the closed position and preventing the sliding door from accidentally opening. The axial distance between the locking cavity 306' and the limit cavity 305' is determined by the opening height of the sliding door 4. At the same time, as shown in FIG. 18, the axial distance between the locking boss 403 and the limit hook 402 is also determined by the opening height of the sliding door 4. Specifically, a guide portion 403a is provided below the locking boss 403, and the guide portion 403a is an inclined surface that is inclined downward from the farthest protruding position of the locking boss 403 and toward the sliding door 4. Preferably, guide portions 402a are provided above and below the limit hook 402. The guide portion 402a is an inclined surface that is inclined downward from the farthest protruding position of the limit hook 402 and downward and toward the sliding door 4.

As shown in FIG. 15 , when the sliding door 4 needs to be opened, the sliding door 4 needs to be pushed inward first, and when the locking boss 403 on the sliding door 4 is disengaged from the locking cavity 306′ on the side plate 3, the sliding door 4 can be opened by pulling upward. When the sliding door 4 needs to be closed, the sliding door 4 can be closed by simply pressing downward. It should be understood that in this embodiment, a biasing device can also be provided to bias the sliding door 4 toward the side plate 3 to ensure that the sliding door 4 is locked in the open position or the closed position.

In the above embodiment, the sliding door 4 or the sliding door 4 together with the pull rod 5 is arranged on one surface of the side plate 3, but it should be understood that the sliding door 4 or the sliding door 4 together with the pull rod 5 can also be clamped in the thickness of the side plate 3. In this case, a locking boss and a limiting hook are arranged on one side surface of the pull rod 5 or the sliding door 4, and a locking part and a limiting part are arranged on the corresponding surface of the through groove of the side plate 3, thereby forming a closing positioning mechanism and an opening positioning mechanism respectively.

The above embodiment describes the situation where the sliding door 4 slides up and down to switch between the open and closed positions, but it should be understood that the sliding door 4 can also slide in any direction within the side panel to switch between the open and closed positions, such as sliding in the horizontal direction.

Preferred embodiments of the present invention have been described above in detail, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
