Abstract
Description
Technical Field
[0001] This utility model relates to the field of laundry detergent bottles, specifically a laundry detergent bottle with a child safety lock to prevent accidental opening. Background Technology
[0002] Laundry detergent bottles are a common type of plastic product, usually made of materials such as high-density polyethylene or polypropylene. They have good chemical stability and corrosion resistance, allowing for safe storage of laundry detergent and preventing leakage and deterioration. At the same time, their design makes it easy for consumers to take out and control the amount used.
[0003] However, current laundry detergent bottles can be easily twisted open. If there are children in the family, at best, it may spill and be wasted; at worst, children may try it because of the smell. This not only causes waste of laundry detergent and increases the family's financial burden, but more importantly, it poses a great safety hazard to children. Summary of the Invention
[0004] Therefore, the purpose of this utility model is to provide a laundry detergent bottle with a child safety lock to prevent accidental opening, so as to solve the technical problem that existing laundry detergent bottles are easily rotated and opened by children, which leads to the spillage and waste of laundry detergent, increases the economic burden on families, and poses great safety hazards to children.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a laundry detergent bottle with a child safety lock to prevent accidental opening, comprising a laundry detergent bottle and a cap, wherein the laundry detergent bottle comprises a bottle body and a cap inlet, a buckle is provided on the lower inner wall of the cap inlet, and a first arc-shaped chamfer is provided on the top edge of the buckle;
[0006] The bottle cap inlet is provided with spring sleeves on both sides, and the two ends of the spring sleeves are respectively provided with a button and a lever;
[0007] The bottle cap includes a cap body, the bottom of which is provided with a deformation ring, which is composed of two half rings and a deformation groove is provided between the two half rings. The bottom of each half ring of the deformation ring is provided with a retaining ring, and the bottom edge of the retaining ring is provided with a second arc-shaped chamfer. The top of the cap body is provided with two directional arrows that are mirrored along the central axis of the cap body.
[0008] By adopting the above technical solution, a core framework to prevent accidental opening is formed through the design of a buckle, a deformation ring, and a double button. The insertion and connection between the bottle cap and the cap body, combined with a spring sleeve and a lever linkage mechanism, ensures that children cannot operate the bottle with one hand, thus improving safety.
[0009] Furthermore, after the cap body is inserted into the bottle cap socket, the deformation ring causes the retaining ring and the buckle ring to engage through tension, thereby locking the bottle cap inside the bottle cap socket.
[0010] By adopting the above technical solution, after the cover is inserted, the deformation ring automatically expands under tension, locking the retaining ring and the buckle ring together. Locking is completed without additional operation, simplifying the usage process and preventing accidental opening.
[0011] Furthermore, the button can be pressed when the two pointers of the directional arrow point in the same direction as the button.
[0012] By adopting the above technical solution, the directional arrow is forced to rotate the bottle cap until the arrow is aligned with the button; otherwise, the button cannot be triggered, thus preventing children from pressing it blindly.
[0013] Furthermore, pressing both buttons simultaneously causes the deformation ring to deform inward through the interaction of the lever and spring, thereby disengaging the retaining ring from the buckle and unlocking the laundry detergent bottle cap.
[0014] By adopting the above technical solution, the two buttons need to be pressed simultaneously to drive the lever, causing the deformation ring to retract and release the retaining ring, making it impossible for a child to operate with one hand.
[0015] Furthermore, the first arc-shaped chamfer cooperates with the second arc-shaped chamfer to guide the retaining ring to slide under the buckle when the bottle cap is inserted into the bottle cap socket.
[0016] By adopting the above technical solution, the first arc-shaped chamfer and the second arc-shaped chamfer bevel cooperate to guide the retaining ring to slide into the bottom of the buckle, thus avoiding jamming during installation.
[0017] Furthermore, the deformation grooves between the deformation rings cause the deformation rings to undergo inward elastic deformation under the pressure of the pressure bar.
[0018] By adopting the above technical solution, the deformation groove causes the deformation ring to shrink inward under pressure, ensuring that the retaining ring is accurately disengaged and avoiding unlocking failure.
[0019] Furthermore, the button is driven by a spring sleeve to press the lever, and automatically resets after being pressed. The directional arrow is used to indicate the rotational alignment position of the bottle cap and the button.
[0020] By adopting the above technical solution, the button is automatically reset by the spring sleeve after being pressed, and the directional arrow simplifies the alignment operation, improving the convenience of use.
[0021] Furthermore, a handle is provided on one side of the bottle body, a cap socket is provided on the top of the bottle body, and a laundry detergent outlet is provided at the center of the cap socket.
[0022] By adopting the above technical solutions, the handle on the bottle provides a gripping fulcrum, and the central design of the laundry detergent outlet avoids liquid residue and side leakage.
[0023] In summary, the present invention has the following main advantages:
[0024] This invention solves the safety hazard of children accidentally opening traditional laundry detergent bottles by setting up an elastic buckle structure composed of a deformation ring and a buckle, and with the help of a two-way press unlocking mechanism. The deformation ring automatically locks the buckle and the buckle together through tension. The buckle can only be released by pressing the buttons on both sides at the same time to drive the pressure rod to retract the deformation ring. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] Laundry detergent bottles with child safety locks to prevent accidental opening, such as Figure 1-5 As shown, the laundry detergent bottle 1 and the cap 2 are included. The laundry detergent bottle 1 includes a bottle body 101 and a cap inlet 103. A buckle 108 is provided on the lower inner wall of the cap inlet 103. A first arc-shaped chamfer 109 is provided on the top edge of the buckle 108.
[0033] Spring sleeves 105 are provided on both sides of the bottle cap inlet 103, and buttons 106 and levers 107 are provided at both ends of the spring sleeves 105 respectively.
[0034] The bottle cap 2 includes a cap body 201. A deformation ring 202 is provided at the bottom of the cap body 201. The deformation ring 202 is composed of two semi-rings, and a deformation groove is provided between the two semi-rings. A retaining ring 203 is provided at the bottom of each semi-ring of the deformation ring 202. A second arc-shaped chamfer 204 is provided at the bottom edge of the retaining ring 203. Two directional arrows 205 are provided at the top of the cap body 201, mirrored along the central axis of the cap body 201. The buckle 108 of the laundry detergent bottle 1 and the deformation ring 202 of the bottle cap 2 are locked together by the retaining rings 203. The spring sleeve 105 has a built-in pressure rod 107 and a button 106 forming a dual trigger mechanism. The split semi-rings and deformation groove of the deformation ring 202 provide elastic deformation space. The directional arrows 205 force rotation and positioning alignment. The first arc-shaped chamfer 109 and the second arc-shaped chamfer 204 guide the retaining ring 203 to slide into the buckle 108 during installation, forming multiple barriers to prevent accidental opening.
[0035] See Figure 3 , Figure 4 After the cap 201 is inserted into the cap socket 103, the deformation ring 202 causes the retaining ring 203 to engage with the buckle 108 through tension, which is used to lock the cap 2 inside the cap socket 103. When the cap 201 is inserted into the cap socket 103, the deformation ring 202 is squeezed and generates tension to push the retaining ring 203 into the buckle 108. The elastic expansion force of the deformation ring 202 ensures that the lock is tight and does not loosen, preventing the cap 2 from falling off during transportation or tilting and causing laundry detergent leakage.
[0036] See Figure 1 , Figure 2 When the two pointers of the directional arrow 205 are in the same direction as the button 106, the button 106 can be pressed. The mirror setting of the directional arrow 205 requires the user to rotate the bottle cap 2 until the arrow 205 and the button 106 of the spring sleeve 105 are completely aligned in the same direction. Only when the button 106 is pressed will it take effect, forming a directional lock mechanism to prevent children from operating randomly.
[0037] See Figure 1 , Figure 4 When both buttons 106 are pressed simultaneously, the spring, in conjunction with the lever 107, causes the deformation ring 202 to deform inward, thereby disengaging the retaining ring 203 from the buckle 108 and unlocking the bottle cap 2 and laundry detergent bottle 1. When both buttons 106 are pressed simultaneously, the lever 107 compresses the deformation ring 202 along the deformation groove to deform elastically towards the center, causing the retaining ring 203 to disengage from under the buckle 108. The coordinated operation of both hands far exceeds the hand coordination ability of children.
[0038] See Figure 3 , Figure 4The first arc-shaped chamfer 109 and the second arc-shaped chamfer 204 cooperate to guide the retaining ring 203 to slide under the retaining ring 108 when the bottle cap 2 is inserted into the bottle cap socket 103. The first arc-shaped chamfer 109 of the retaining ring 108 and the second arc-shaped chamfer 204 of the retaining ring 203 form a sloped slide rail. When the bottle cap 2 is inserted, the retaining ring 203 is automatically guided to slide under the retaining ring 108, reducing assembly resistance and preventing damage from hard collisions.
[0039] See Figure 4 The deformation grooves between the deformation rings 202 cause the deformation rings 202 to undergo inward elastic deformation under the pressure of the pressure rod 107. The deformation grooves between the half rings of the deformation rings 202 provide a directional deformation channel. When the pressure rod 107 applies force, it causes the retaining ring 203 to linearly displace and disengage from the retaining ring 108, preventing deformation and twisting from causing unlocking jamming.
[0040] See Figure 1 , Figure 4 Button 106 drives lever 107 via spring sleeve 105, and automatically resets after being pressed. Directional arrow 205 is used to indicate the rotational alignment position of bottle cap 2 and button 106. Button 106 automatically resets to its initial position after being pressed by the spring inside spring sleeve 105. The mirror design of directional arrow 205 intuitively indicates the rotational alignment direction, reducing the user's learning cost.
[0041] See Figure 1 , Figure 2 A handle 102 is provided on one side of the bottle body 101, and a cap socket 103 is provided on the top of the bottle body 101. A laundry detergent outlet 104 is provided at the axis of the cap socket 103. The handle 102 makes it easy to hold the laundry detergent bottle 1 with one hand. The laundry detergent outlet 104 is located at the axis of the cap socket 103. After unlocking, the liquid flow is concentrated and discharged without any off-center residue, reducing waste.
[0042] The implementation principle of this embodiment is as follows: First, when the cap 201 of the bottle cap 2 is inserted into the cap socket 103 of the laundry detergent bottle 1, the second arc-shaped chamfer 204 at the bottom of the bottle cap 2 contacts the first arc-shaped chamfer 109 at the top of the buckle 108 inside the cap socket 103 and guides the retaining ring 203 to slide into the buckle 108. At this time, the deformation ring 202 is squeezed and deformed and expands through its own tension, causing the retaining ring 203 to form a locked engagement with the buckle 108.
[0043] When in use, rotate the bottle cap 2 until the direction arrow 205 on its top is fully aligned with the button 106 on the spring sleeve 105. After alignment, press the buttons 106 on both sides simultaneously. The spring sleeve 105 drives the pressure rod 107 to squeeze the deformation ring 202. After being pressed, the deformation ring 202 elastically deforms towards the center along the deformation groove, causing the retaining ring 203 to disengage from the limit of the buckle 108, thus unlocking. After the external force is released, the spring inside the spring sleeve 105 pushes the button 106 and the pressure rod 107 to automatically reset.
[0044] The handle 102 on the side of the bottle body 101 provides a gripping fulcrum, and the laundry detergent outlet 104 on the axis of the cap 103 opens the liquid supply after unlocking. The entire operation requires synchronous alignment and pressing to prevent children from accidentally opening it, thus achieving the effect of preventing accidental opening.
