Description

Technical Field

[0001] This utility model relates to the field of plastic packaging bottle technology, and in particular to a two-way sealed plastic packaging bottle for both food and cosmetics. Background Technology

[0002] Plastic packaging bottles are widely used in food and cosmetic storage and usage scenarios due to their advantages such as low cost, light weight, and portability. Although existing two-way sealed plastic packaging bottles can improve leak-proof and preservation performance through double sealing structure, they still have some shortcomings in cross-category sharing scenarios: such as the lack of protection against child-proofing, which makes it easy for children to accidentally open the packaging to take out cosmetics or food, causing the risk of accidental ingestion. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a two-way sealed plastic packaging bottle for food and cosmetics.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a bidirectional sealed plastic packaging bottle for food and cosmetics, comprising a bottle body, wherein a first cavity and a second cavity are provided inside the bottle body, and a bottle mouth tube is fixedly connected to the top of both the first cavity and the second cavity. A bottle cap is threadedly connected to the outer wall of the bottle mouth tube, and an anti-accidental opening mechanism is provided on the outer side of the bottle cap. The anti-accidental opening mechanism includes a fixing block fixedly connected to the outer wall of the bottle cap and a fixing seat fixedly connected to the outer wall of the bottle mouth tube near the bottom. A slot is provided on the top surface of the fixing seat. A slider is slidably connected inside the fixing block. An insert rod is fixedly connected to the bottom of the slider. The bottom end of the insert rod is inserted into the inside of the slot. A push plate is fixedly connected to the side of the slider. A spring is fixedly connected to the top of the slider. The spring is fixedly connected to the top surface of the internal cavity of the fixing block.

[0005] Preferably, a sealing gasket is fixedly connected to the inner top surface of the bottle cap, and the bottom surface of the sealing gasket abuts against the top of the bottle mouth tube.

[0006] Preferably, the front side of the push plate is provided with several anti-slip ridges.

[0007] Preferably, the bottle body is made of transparent plastic.

[0008] Preferably, the outer wall of the bottle body is provided with scale lines at the locations corresponding to the first cavity and the second cavity.

[0009] Preferably, a limiting plate is fixedly connected to the left side of the fixing seat, and the top right side of the limiting plate abuts against the bottom left side of the fixing block.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, an anti-accidental opening mechanism is set up. The anti-accidental opening mechanism achieves the anti-accidental opening function through the elastic linkage of "slider-insert rod-spring". Under normal conditions, the spring is in a naturally extended state, pushing the slider downward so that the bottom end of the insert rod is inserted into the slot of the fixed base. At this time, the engagement of the insert rod and the slot restricts the rotation of the bottle cap, forming an anti-accidental opening lock. When an adult opens the bottle, they need to push the slider upward with the push plate to compress the spring and drive the insert rod out of the slot, releasing the restriction on the rotation of the bottle cap. Then, the bottle cap can be opened by rotating it counterclockwise. After tightening the bottle cap clockwise, the push plate is released, the spring returns to its original position, pushing the slider and the insert rod downward, and the insert rod is reinserted into the slot, restoring the anti-accidental opening state. This structure requires the simultaneous completion of two actions: "pushing the plate upward" and "rotating the bottle cap". The push plate needs to apply a certain upward pushing force. Children, due to insufficient strength and inability to master the complex operation logic, are unlikely to accidentally open the bottle, thus fundamentally eliminating the safety risk of children accidentally ingesting food or cosmetics.

[0011] 2. In this utility model, by setting a limiting plate on the left side of the fixed base, when the bottle cap screw is tightened clockwise, the bottom left side of the fixed block abuts against the limiting plate, thereby realizing quick alignment of the insertion rod and the slot without repeated correction, improving the convenience of inserting the insertion rod into the slot.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. Embodiment 1: As shown... Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a two-way sealed plastic packaging bottle for food and cosmetics, including a bottle body 1, the bottle body 1 having a first cavity 3 and a second cavity 4 inside, the top of the first cavity 3 and the top of the second cavity 4 being fixedly connected to a bottle neck tube 6, the outer wall of the bottle neck tube 6 being threadedly connected to a bottle cap 2, the outer side of the bottle cap 2 being provided with an anti-accidental opening mechanism 7, the anti-accidental opening mechanism 7 including a fixing block 701 fixedly connected to the outer wall of the bottle cap 2 and a fixing seat 702 fixedly connected to the outer wall of the bottle neck tube 6 near the bottom, the top surface of the fixing seat 702 having a slot 11 for fixing... A slider 703 is slidably connected inside block 701. A rod 704 is fixedly connected to the bottom of slider 703. The bottom end of rod 704 is inserted into the slot 11. A push plate 706 is fixedly connected to the side of slider 703. A spring 705 is fixedly connected to the top of slider 703. Spring 705 is fixedly connected to the top surface of the internal cavity of fixed block 701. A sealing gasket 5 is fixedly connected to the top surface of the bottle cap 2. The bottom surface of sealing gasket 5 abuts against the top of bottle mouth tube 6. Several anti-slip ribs 9 are provided on the front of push plate 706. Bottle body 1 is made of transparent plastic material.

[0015] The beneficial effects achieved in this embodiment 1 are as follows: By setting the anti-accidental opening mechanism 7, the anti-accidental opening mechanism 7 realizes the anti-accidental opening function through the elastic linkage of "slider 703 - insertion rod 704 - spring 705". Under normal conditions, the spring 705 is in a naturally extended state, pushing the slider 703 downward, so that the bottom end of the insertion rod 704 is inserted into the slot 11 of the fixed seat 702. At this time, the engagement of the insertion rod 704 and the slot 11 restricts the rotation of the bottle cap 2, forming an anti-accidental opening lock. When an adult opens the bottle cap, the slider 703 needs to be pushed upward by the push plate 706 to compress the spring 705 and drive the insertion rod 704 out of the slot 11, releasing the restriction on the rotation of the bottle cap 2. Then, the bottle cap 2 can be opened by rotating it counterclockwise. After tightening the bottle cap 2 clockwise, the push plate 706 is released, the spring 705 returns to its original position, pushing the slider 703 and the insertion rod 704 downward, and the insertion rod 704 is reinserted into the slot 11, restoring the anti-accidental opening state. This structure requires two simultaneous actions: "pushing the plate 706 upwards" and "rotating the cap 2" to open. The plate 706 requires a certain upward pushing force, making it difficult for children to accidentally open due to insufficient strength and inability to grasp the complex operational logic. This fundamentally eliminates the safety risk of children accidentally ingesting food or cosmetics. The sealing gasket 5 and the bottle neck tube 6 abut against each other, forming a two-way seal through the threaded connection between the cap 2 and the outer wall of the bottle neck tube 6. Anti-slip ridges 9 on the front of the plate 706 provide sufficient friction when pushing the plate 706 upwards, making the operation more convenient and preventing slippage. The bottle body 1 is made of transparent plastic, allowing for direct observation of the contents inside.

[0016] Example 2: Figure 1 - Figure 5 As shown, scale lines 8 are provided on the outer wall of the bottle body 1 at the locations corresponding to the first cavity 3 and the second cavity 4. A limiting plate 10 is fixedly connected to the left side of the fixing seat 702, and the top right side of the limiting plate 10 abuts against the bottom left side of the fixing block 701.

[0017] The beneficial effects achieved in this embodiment 2 are as follows: by setting the scale line 8, the remaining capacity of the contents can be accurately displayed, which makes it easier for users to plan their use reasonably, improves the practicality and accuracy of the product, and is suitable for quantitative dispensing scenarios; by setting the limiting plate 10 on the left side of the fixed base 702, when the bottle cap 2 is screwed on, the bottom left side of the fixed block 701 abuts against the limiting plate 10, thereby realizing the quick alignment of the insertion rod 704 and the slot 11 without repeated correction, improving the convenience of inserting the insertion rod 704 into the slot 11.

[0018] The working principle of this embodiment is as follows: When using this bidirectional sealed food and cosmetic shared plastic packaging bottle, the first cavity 3 can be used to store food, and the second cavity 4 can be used to store cosmetics, realizing independent storage across categories. When opening, adults need to first push the push plate 706 upwards using the anti-slip ribs 9 on the front of the push plate 706. The push plate 706 drives the slider 703 to slide upwards in the cavity of the fixed block 701, while compressing the spring 705. The slider 703 moves upwards, causing the insertion rod 704 to disengage from the slot 11 of the fixed seat 702, releasing the rotation restriction on the bottle cap 2. Then, the bottle cap 2 is rotated counterclockwise. The bottle cap 2 moves upwards through the inner wall thread engaging with the outer wall thread of the bottle mouth tube 6. The sealing gasket 5 disengages from the top of the bottle mouth tube 6, allowing the bottle cap 2 to be opened and the contents of the corresponding cavity to be accessed. The transparent bottle body 1 can be opened. By observing the position of the contents in advance, it can be predicted without opening. When closing, rotate the bottle cap 2 clockwise. The bottle cap 2 moves downward along the thread of the bottle mouth tube 6. After the sealing gasket 5 contacts the top of the bottle mouth tube 6, continue to tighten the bottle cap 2 until the sealing gasket 5 and the top of the bottle mouth tube 6 are tightly abutted, forming a two-way seal. When the bottom left side of the fixing block 701 abuts the top right side of the limiting plate 10, the insertion rod 704 and the slot 11 are precisely aligned. At this time, release the push plate 706. The spring 705 returns to its original position under the action of elastic potential energy, pushing the slider 703 to move downward. The slider 703 drives the insertion rod 704 to insert into the slot 11, re-forming the anti-accidental opening lock and completing the closing operation. The scale line 8 on the outer wall of the bottle body 1 can display the remaining capacity of the contents in the two cavities in real time, which is convenient for users to replenish in time according to the amount used. Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
