Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a press-type elastic opening lunch box. Background Technology

[0002] Lunch boxes, as portable food containers, are widely used in daily life, office work, and outdoor activities. To ensure the airtightness of the lunch box and prevent food or soup from spilling out, existing lunch boxes typically consist of a box body, a lid, and a flip-top mechanism located on the edge of the lid or box body. The flip-top mechanism is mostly made of one-piece molded plastic, and its locking mechanism mainly relies on the interference fit between the protruding edge on the inside of the flip-top and the groove on the box body. That is, when closing the lunch box, the user needs to press the flip-top firmly to make it elastically deform and lock into the locking position; when opening the lunch box, the user needs to apply force in the opposite direction, using their fingers to forcefully pull the flip-top outward to overcome the frictional resistance generated by the interference fit and disengage it from the groove.

[0003] However, the aforementioned existing technology has obvious shortcomings in use. Because the interference fit structure requires a large locking force to maintain the seal, the resistance when opening is relatively large. Users, especially children, the elderly, or those with wet or slippery hands, often find it difficult to pry it open, making the operation laborious and easily damaging to nails or fingers. Secondly, when users forcefully pry the flap to disengage from the slot, the excessive force often causes inertial rebound, resulting in violent vibration of the lunchbox, which can easily cause soup or food to splash or spill, staining clothes or tabletops. In addition, long-term forceful prying and interference friction can cause fatigue stress or wear on the plastic material at the flap connection, which can easily lead to loosening of the flap, failure of the seal, or even breakage and damage, reducing the lifespan of the lunchbox.

A slot is formed on the side wall of the lid 2 corresponding to the position of the silicone block 11. The shape of the base of the silicone block 11 is adapted to the slot and is fixedly embedded to prevent it from falling off under repeated pressure. The side wall of the lid 2 is rotatably connected to... There is a flip-top 12, and a silicone block 11 is in the shape of an outwardly protruding V-shaped bend. The side of the silicone block 11 away from the lid 2 is adapted to contact the inner wall of the flip-top 12. A sliding buckle 16 is slidably connected to the side wall of the box body 1. A limiting part 17 is fixedly connected to the end of the sliding buckle 16 near the outside of the box body 1.

A button block 21 is slidably connected to the inside of the bottom of the box body 1. A push block 22 is fixedly connected to the end of the button block 21 near the inside of the box body 1.

[0020] Reference Figures 5-6 A snap-fit ​​part 13 is fixedly connected to the bottom of the flip-top 12 near the side of the lid 1. A protrusion is fixedly installed on the bottom side of the snap-fit ​​part 13 away from the inside of the box body 1. The protrusion is used to further contact the limiting part 17 and limit the position of the snap-fit ​​part 13. A groove 14 is opened on the outer wall of the box body 1. The snap-fit ​​part 13 is adapted to fit through the groove 14 and inserted into the inside of the box body 1. A vertical sliding groove 15 is opened on the inner wall of the box body 1. The snap-fit ​​16 is slidably connected to the inside of the sliding groove 15. The top of the limiting part 17 is higher than the snap-fit ​​1. At the top of 6, the inclined part 18 is inclined downward away from the sliding buckle 16. The end of the snap fastener 13 away from the flip buckle 12 is adapted to contact the inclined part 18 and is adapted to abut against the end of the limiting part 17 near the sliding buckle 16. The inclined part 19 is inclined downward away from the sliding buckle 16. The end of the push block 22 away from the button block 21 is provided with an inclined surface adapted to slide with the inclined part 19. The bottom end of the sliding buckle 16 is fixedly connected to the reset spring 20. The bottom end of the reset spring 20 is fixedly connected to the inner wall of the box body 1.

[0021] Reference Figures 1-4The top of the lid 1 2 is rotatably connected to the lid 2 3. The bottom right side of the lid 2 3 is fixedly connected to the snap fastener 4. The snap fastener 4 and two buckles 9 are adapted to engage with each other. The surface of the lid 2 3 is provided with a torsion spring 5. The torsion spring 5 is sleeved at the connection between the lid 2 3 and the lid 1 2 and is fixedly connected inside the lid 1 2. The inside of the lid 1 2 is provided with a tableware cavity 6. The right side of the inside of the tableware cavity 6 is fixedly installed with a hollow fixing block 7. The inner wall of the hollow fixing block 7 is slidably connected to a slider 8. The front and rear sides of the top of the slider 8 are fixedly connected with buckles 9. The connection between the buckles 9 and the slider 8 has an elastic deformation area with a certain buffer stroke. The snap fastener 4 and the two buckles 9 are adapted to engage with each other. The bottom wall of the hollow fixing block 7 is fixedly installed with a return spring 10. The top of the return spring 10 and the bottom of the slider 8 are adapted to contact each other.

[0022] In this invention, when the lid 2 3 is closed, the torsion spring 5 is in a deformed, energy-storing state, covering the tableware cavity 6 to prevent dust from entering. At this time, the two latches 9 naturally approach each other and engage with the latching member 4, thus fixing the lid 2 3. When the user needs to remove the tableware, they simply press down on the lid 2 3, causing the latching member 4 to move downwards and press against the slider 8. The slider 8 then compresses the return spring 10 downwards. During the downward movement of the slider 8, the latches 9 located on both sides of its top end move into the hollow fixing block 7. Due to the limitation of the inner diameter of the hollow fixing block 7, the outer walls of the latches 9 are compressed by the inner wall of the hollow fixing block 7, causing the two latches 9 to overcome their own elastic resistance. The lids move closer together; at this point, the user releases their hand and no longer applies pressure to the lid 3. The bottom return spring 10 and torsion spring 5 instantly release their rebound force, quickly pushing the slider 8 and buckle 9 upward. This causes the slider 8 to be pushed upward by the return spring 10 for a short time, exceeding the original length of the return spring 10. At this point, the buckle 9 at the top of the slider 8 is pushed out of the hollow fixing block 7. After the buckle 9 moves out of the restraint range of the hollow fixing block 7, the two buckles 9 quickly open to both sides and move away from each other under their own elastic restoring force, thereby causing the locking piece 4 to disengage from the buckle 9 and release the lock. Subsequently, the lid 3 automatically rotates upward and opens under the continuous torque of the torsion spring 5, making it convenient for the user to take out the tableware.

[0023] When the user closes the lid 12 onto the box body 1 and prepares to lock it, they need to manually rotate the flip 12 to bring it closer to the box body 1. During the rotation of the flip 12, the inner wall of the flip 12 will contact and press the silicone block 11 fixed on the side wall of the lid 12. The silicone block 11 will undergo elastic deformation under pressure, accumulating a reverse rebound force. At the same time, the snap-fit ​​part 13 at the bottom of the flip 12 passes through the groove 14 into the interior of the box body 1 and contacts the inclined part 18 at the top of the sliding buckle 16. Since the inclined part 18 is set as an inclined surface, the pushing force of the snap-fit ​​part 13 will be converted into a downward force. The force forces the sliding buckle 16 to slide downwards within the slide groove 15 and compress the bottom return spring 20. When the latching part 2 13 passes the top of the inclined part 18, the sliding buckle 16 loses the downward pressure restriction of the latching part 2 13 and quickly returns to its original position under the rebound force of the return spring 20. At this time, the side wall of the limiting part 17 on the sliding buckle 16 just abuts against the protruding part at the bottom of the latching part 2 13, thereby forming a block and firmly locking the latching part 2 13 inside the box body 1. By operating the flip buckles 12 around the lid 2 in this way, the lunch box can be sealed and closed.

[0024] When the user needs to open the lunchbox, there is no need to forcefully pull the flip 12. Simply press the button block 21 towards the inside of the box body 1. The button block 21 moves inward, causing the push block 22 to move synchronously. The inclined surface at the front end of the push block 22 will slide and engage with the inclined part 19 at the bottom of the sliding buckle 16. As the push block 22 goes deeper, the inclined part 19 is squeezed, which again causes the sliding buckle 16 to be pushed downward, thereby driving the sliding buckle 16 to overcome the resistance of the return spring 20 and slide downward. When the sliding buckle 16 moves down to a certain distance, the limiting part 17 descends and disengages from the blocking effect on the latch 13. At this time, the latch 13 is no longer restrained. Then, the previously compressed and stored silicone block 11 releases its rebound force, pushing the flip 12 to rotate outward and pop open, thereby realizing the automatic unlocking and opening of the flip 12. The user can then easily open the box lid 1 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
