As used in this specification and the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally employed in its sense including "and/or" unless the context clearly dictates otherwise.
In the following description, for the purposes of illustrating various disclosed embodiments, certain specific details are set forth in order to provide a thorough understanding of the various disclosed embodiments. One skilled in the relevant art will recognize, however, that the embodiments may be practiced without one or more of the specific details.
Fig. 1 and 2 are perspective views of the folding carton 100 of the present invention with the side panels in an upright position and a folded position, respectively. As shown, the folding carton 100 comprises a base 1, a pair of opposing first side panels 2, 2 and a pair of opposing second side panels 3, 3. Wherein the first side panel 2, 2 and the second side panel 3, 3 are adjacent to each other and define an inner volume together with the base 1 in an upright position. Preferably, the first side panel 2 and the second side panel 3 are made of a high strength material such as a high strength plastic. Generally, the length of the first side plate 2 is shorter than the length of the second side plate 3 to form a folding box of a substantially rectangular parallelepiped shape. Therefore, the first side plate 2 is also referred to as a short side plate, and the second side plate 3 is also referred to as a long side plate. It will be appreciated that the first side panel 2 and the second side panel 3 may also be of the same length to form a square folding box.
The bottom ends of the first and second side panels 2, 3 are connected to the four edges of the upper surface of the base 1 by hinge structures 5. One of the four edges is provided with an upwardly projecting wall 4, the height of the wall 4 being substantially equal to the thickness of the side panel provided on the adjacent pair of edges, the height of the wall 4 defining a space for receiving the adjacent side panel folded onto the base 1. Thus, the first side panel 2 and the second side panel 3 can be successively folded over the base 1, with the folding box 100 in a folded state. In the shown embodiment the lower end of the second side plate 3 is hinged to the protruding wall 4 by means of a hinge structure 5. The adjacent first and second side panels 2, 3 are releasably lockable to each other by locking formations. The locking structure is formed by the locking portion 22 and the stopper groove 34 described below. When the lock portion 22 is located in the stopper groove 34, the first side plate 2 and the second side plate 3 are locked with respect to each other, and when the lock portion 22 is disengaged from the stopper groove 34, the first side plate 2 and the second side plate 3 are unlocked.
The first side plate 2 is provided with an operating mechanism 21 and a lock portion 22. Wherein the locking portion 22 may be a protrusion formed on an edge of the first side plate 2, or may be formed by an inner edge of the first side plate 2 as shown in the illustrated embodiment. The inner edge comprises a flange formed by the portion of the inner layer 23 of the first side panel 2 extending beyond the outer layer 24 and projecting towards the second side panel 3. The operating mechanism 21 has an operating handle 211 and a spring 212, and the operating handle 211 is operable to move between a first position and a second position relative to the first side plate, in this embodiment, up and down along the first side plate, to drive the locking structure to achieve unlocking and locking. The handle 211 is repositionable by a spring 212, as will be described in further detail below.
As shown in fig. 3-10, the second side plate 3 is provided with elastic members 31. The first end of the elastic member 31 is detachably mounted on the inner side of one end of the second side plate 3, the second end of the elastic member 31 is a free end and is sequentially provided with a first limiting portion 32 and a second limiting portion 33, and a limiting groove 34 is formed between the first limiting portion 32 and the second limiting portion 33. When the first side panel 2 and the second side panel 3 of the folding box 100 are in the erected state, the locking portion 22 of the first side panel 2 is located in the stopper groove 34, thereby locking the first side panel 2 and the second side panel 3 relative to each other. The operating handle 211 is operatively movable relative to the first side plate 2 between a first position below and a second position above. Wherein the movement of the operating member 211 toward the second position can drive the elastic member 31 to be elastically deformed upward, i.e., the stopper groove to move upward, so that the locking portion 22 is disengaged from the stopper groove 34, thereby releasing the locking between the first side plate 2 and the second side plate 3. After the operating handle 211 returns to the first position, the elastic member is reset, i.e., restored.
Specifically, as shown in fig. 4, the elastic member 31 has an elongated body 301. One end of the elongated body 301, i.e., the first end of the elastic member 31, is provided with a mounting portion 302. The other end of the elongated body 302, i.e., the second end of the elastic member, is a free end and is provided with a first stopper protrusion 32 and a second stopper protrusion 33 which protrude from the elongated body toward the inside of the folding box in order and are spaced apart from each other. A limiting groove 34 is arranged between the first limiting bulge 32 and the second limiting bulge 33. The mounting portion 302 is T-shaped in cross-section. Correspondingly, a clamping groove with a T-shaped cross section is formed on the second side plate, and the clamping groove is matched with the mounting part 302 to detachably mount the elastic part 31 on the second side plate.
As shown in fig. 6, a third limiting protrusion 303 protrudes from the surface of the mounting portion of the elastic member 31. In this embodiment, the third stopper projection 303 projects from the rear side surface of the mounting portion. It will be appreciated that the third stop lug may also project from other side surfaces of the mounting portion, for example from the front side surface. Accordingly, a second limiting groove 308 is formed in the mounting hole 307 of the second side plate, and the third limiting protrusion 303 is engaged with the second limiting groove, so as to fix the elastic member 31 on the second side plate, which will be further described below.
The lower surface of the first stopper protrusion 32 is provided with a guide slope 304. The guide slope 304 is used to guide the locking portion 22 during the locking of the folding box so that the locking portion 22 smoothly enters the stopper groove 34. The second stopper protrusion 33 serves as an actuating portion at the same time, and the lower surface thereof is a driving surface 305. The driving surface 305 cooperates with the end of the operating handle 211 to drive the movement of the elastic element 31 to effect unlocking. The driving surface 305 is a flat surface. Accordingly, the top surface of the operating handle 211 that engages the driving surface 305 is also planar. It should be understood that the matching structure between the second limiting protrusion 33 and the operating handle 211 may also adopt other structures as long as it can enable the upward movement of the operating handle 211 to drive the second limiting protrusion 33 to move upward, so as to enable the limiting groove to move upward.
The inner side surface of the second side plate 3 at a position corresponding to the elastic member 31 is formed with a concave portion 306. The top surface of the recess 306 is spaced apart from the top surface of the elastic member 31 by a predetermined interval. The predetermined interval is set such that the elastic member 31 has a space to be deformed upward. Thereby, the elastic member 31 can move in the recess 306, so that the locking portion 22 on the second side plate can enter or leave the stopper groove 34. One side of the recess 306 is formed with a mounting hole 307. The first end of the elastic member 31 is detachably mounted to the mounting hole 307. The mounting hole 307 is T-shaped in cross-section. A second limiting groove is further disposed in the mounting hole 307, and the second limiting groove cooperates with the third limiting protrusion on the elastic member to fixedly mount the elastic member on the second side plate. After mounting, the main body portion of the elastic member 31 is located in the recess. Therefore, the use of the box body is prevented from being accidentally damaged and partially influenced. The distal ends of the first and second position-limiting portions extend beyond the inner side surface of the second side plate, whereby they can be engaged with the operating knob and the locking portion on the first side plate. As shown in fig. 14 to 15, the operating handle 211 has an operating handle 2111 and handle driving portions 2112 at both ends of the operating handle 2111. Specifically, in the illustrated embodiment, the operating handle 211 has a flat shape, and the handle driving portions 2112 are top surfaces of both ends of the operating handle 2111, which are preferably flat surfaces. The operating handle 211 is arranged to be movable up and down with respect to the first side plate 2. When the operating handle 211 moves upward, the top surface (handle driving portion) thereof abuts against the bottom surface of the second stopper portion 33 of the elastic member. Thereby, the elastic member is driven to deform upward, so that the limiting groove 34 on the elastic member is disengaged from the locking part, and unlocking is realized. In this embodiment, the width of the operating handle 211 is substantially equal to the width of the first side plate 2. It is understood that the operating handle 211 may take other shapes without departing from the scope of the present invention.
The coupling of the operating handle 211 to the first side plate 2 is seen in fig. 16-19. In the embodiment shown, the first side panel 2 is composed of an inner layer 23 and an outer layer 24 and a reinforcing rib provided between and fixedly connecting the inner layer and the outer layer. Wherein the operating handle 211 is mounted between the inner layer 23 and the outer layer 24. A window is provided in the outer layer 24 to facilitate access to the operating handle 211 by an operator. In the illustrated embodiment, the outer layer 24 is windowed from the bottom of the first side panel 2 at a location corresponding to the operating handle 2111 of the operating handle 211, but it should be appreciated that the window size may be varied as desired without departing from the scope of the invention.
The side of the operating handle 211 facing the first side plate 2 is shown in fig. 15. A locking groove 2114 is provided on the side of the operating handle 211 facing the first side plate 2. In the illustrated embodiment, two card slots 2114 are provided. As shown in fig. 16 to 17, a limiting strip 25 is provided on the outer side of the inner layer 23 of the first side plate 2, and the length of the limiting strip 25 is smaller than the length of the notch 2114 and can be inserted into the notch 2114, so that the limiting strip can slide up and down relative to the notch 2114, thereby realizing the up and down movement of the operating handle 211 relative to the first side plate 2. In fig. 16, the operating handle 211 is partially cut away to show the fitting relationship between the notch 2114 and the stopper bar 25. An enlarged view of the cut-away portion is shown in fig. 17. Opposite slot walls are provided on both sides of the slot 2114, one of which is provided with a protrusion 2115 at an edge close to the inner layer 23, and the limiting strip 25 is provided with a protrusion 251 at an edge of the inner layer 23 remote from the first side plate 2, which extends towards the slot wall provided with the protrusion 2115. Thus, when the stopper bar 25 is inserted into the notch 2114, the protrusion 2115 and the protrusion 251 are engaged with each other, thereby preventing the operating handle 211 from being disengaged from the first side plate 2.
Further, the operating mechanism 21 includes a handle return member that is associated with the operating handle 211 and biases the operating handle 211 toward the first position. In the embodiment shown in the drawings, the handle returning member is a spring plate 212, see fig. 15. Referring to fig. 20 to 21, the resilient piece 212 is detachably attached to the top end of the operating handle 2111. In the illustrated embodiment, the spring 212 is substantially V-shaped. The cross section of one side of the V-shape or the tail end of one side is in a T shape. Correspondingly, a T-shaped slot 2116 is provided at the top end of the operating handle 2111 of the operating handle 211. The inner wall of the slot 2115 is also provided with a stop protrusion 2117. Correspondingly, the corresponding part of the elastic sheet 212 is also provided with a limit protrusion 2121. The stopper protrusion 2117 is engaged with the stopper protrusion 2121, thereby fixedly coupling the resilient piece 212 to the operating handle 211.
The elastic sheet can be inserted into the T-shaped slot 2116 in the horizontal direction, so that the operation handle 211 and the elastic sheet 212 are connected. The other end of the spring plate 212 abuts against the baffle inside the first side plate. When the operating handle 211 is located at the first position below, the elastic piece 211 is in an initial state. When the operating handle 211 moves upward, the elastic piece 212 moves upward along with the operating handle 211 and is elastically deformed. When the operating handle 211 is moved to the second position, the resilient piece 212 is deformed to the maximum, and its resilient force is also maximized. The elastic force can return the operating handle 211 to the first position after the operator releases the operating handle 2111.
However, it should be understood that the handle returning member is not limited to the resilient plate 212, and a spring may be provided. For example, one end of the spring is fixed with respect to the first side plate 2, and the other end is fixedly connected to the operating handle 211, so that when the operating handle 211 moves upward, a downward pulling force is applied to the operating handle 211.
In addition, in order to achieve a firm connection between the first side plate 2 and the second side plate 3 in the locked state, a snap structure 40 is further provided at the edge of the side plates, and as shown in the figure, the snap structure may adopt any suitable structure which is known or to be developed, and will not be described in detail herein.
The operation of the folding box 100 according to the invention is as follows. When the folding box 100 needs to be unfolded from the folded state to the use state, the second side plate 3 is erected first, and then the first side plate 2 is erected, so that the locking part 22 is engaged in the limiting groove 34. When the folding box 100 needs to be folded and stored from the using state, the operating handle 211 is lifted up, and along with the movement of the operating handle 211, the handle driving part on the operating handle pushes the elastic piece upwards, so that the elastic piece 31 is deformed upwards, the locking part 22 is separated from the limiting groove 34, and the locking between the first side plate 2 and the second side plate 3 is released.
Fig. 22-25 show a folding carton 600 according to another embodiment of the present invention. The folding box 600 of the present embodiment is different from the folding box 100 of the previous embodiment in that the elastic member 601 is substantially the same, and the details are not described herein. As shown in fig. 22 to 25, the elastic member 601 of the folding box 600 is different from the elastic member 31 of the folding box 100 mainly in that the elastic member 601 eliminates the second stopper protrusion 33 of the elastic member 31. Specifically, the elastic member 601 has an elongated body 602. One end of the strip-shaped body is provided with a mounting part 603, and the other end is sequentially provided with a first limit bulge 604 and an actuating part 605. The first limiting protrusion 604 protrudes from the elongated body toward the inside of the folding box. The lower surface of the first position-limiting protrusion 604 is provided with a guide slope. Thus, when locked, the locking portion 22 on the first side plate 2 is located between the first limit projection 604 and the first side plate.
The folding box 600 operates as follows. When the folding box 600 needs to be unfolded from the folded state to the use state, the second side plate 3 is erected, and then the first side plate 2 is erected, so that the locking part 22 is clamped between the first limiting protrusion 604 and the first side plate 2. When the folding box 600 needs to be folded and stored from the using state, the operating handle 211 is lifted up, and along with the movement of the operating handle 211, the handle driving part on the operating handle drives the actuating part 605, specifically, the lower surface of the actuating part 605 is driven, the elastic piece 601 is pushed upwards, and therefore the elastic piece 601 is deformed upwards, the locking part 22 is disengaged from the first limiting protrusion 604, and the locking between the first side plate 2 and the second side plate 3 is released.
Figures 26-33 show a folding carton 700 according to another embodiment of the invention. The folding box 700 of this embodiment is different from the folding box 100 of the above embodiment in the elastic member 701 and the operation handle 705, and the working principle thereof, and the rest is substantially the same, and will not be described in detail. As shown in fig. 26 to 33, the elastic member 701 of the present embodiment has an elongated arc-shaped body 702. The elongated arc-shaped body is such that the ends of the elastic member 701 will protrude out of the inner side surface of the side plate after being mounted to the side plate. Therefore, the elongated arc-shaped body 702 can be used as the first limiting part and has a guiding function in the vertical locking process of the side plate.
One end of the elongated arc-shaped body 702 is provided with a mounting portion 703, and the other end serves as a first limiting portion 704. Further, a back portion 706 at the other end of the elongated arc-shaped body 702 extends downward to a direction away from the elongated arc-shaped body to integrally form an actuating portion 707. When locked, the locking portion 22 on the first side plate 2 is located between the first position-limiting portion 704 and the first side plate. Further, the elastic member 701 is also disposed such that the bottom surface 309 of the recess 306 of the second side plate 3 is spaced apart from the back surface 708 of the elastic member by a predetermined interval after installation, thereby providing a space for the elastic member 701 to deform to the outside of the case.
As shown in fig. 31, the structure of the operating handle 705 is substantially the same as that of the operating handle 211 of the folding box 100 of the above embodiment, except that the end of the operating handle is provided with a guide structure 7051, and the rest is the same, and will not be described in detail. The guide structure 7051 is a guide ramp. In the unlocking process, the guide structure is matched with the actuating part 707 on the elastic piece to drive the elastic piece to deform towards the outer side of the box body, so that the locking part is separated from the first limiting part 704 on the elastic piece, and unlocking is realized.
The folding box 700 operates as follows. When the folding box 700 needs to be unfolded from the folded state to the use state, the second side plate 3 is erected, and then the first side plate 2 is erected, so that the locking portion 22 is clamped between the first limiting portion 704 and the first side plate 2. In the process of erecting the first side plate 2, the locking portion 211 thereon passes over the first limiting portion and enters between the first limiting portion and the first side plate under the guidance of the portion of the elastic piece 701 protruding out of the inner wall of the box body. When the folding box 700 needs to be folded and stored from the use state, the operating handle 211 is lifted up, and along with the movement of the operating handle 211, the handle driving part on the operating handle 211 drives the actuating part 705, specifically, the guide inclined surface 7051 of the handle drives the lower surface of the actuating part 705, the elastic piece 701 is pushed towards the outer side of the box body, and therefore the elastic piece 701 is deformed outwards, the locking part 22 is disengaged from the first limiting part 704, and the locking between the first side plate 2 and the second side plate 3 is released.
The folding box 100 of the invention has simple and convenient locking operation, light unlocking and locking force, no damage to the side plates and correspondingly prolonged service life of the folding box 100. In addition, if any one component in the whole locking mechanism is damaged, such as the handle, the elastic sheet and/or the elastic piece, the locking mechanism can be conveniently replaced.
While the preferred embodiments of the present invention have been illustrated and described in detail, it should be understood that various changes and modifications of the invention can be effected therein by those skilled in the art after reading the above teachings of the invention. Such equivalents are intended to fall within the scope of the claims appended hereto.
