Description

Technical Field

[0001] This invention belongs to the field of packaging containers, and in particular relates to a packaging bottle with a detachable inner bag and its recycling and separation device. Background Technology

[0002] Packaging bottles play a vital role in many fields, primarily for storing substances, protecting the contents, and safeguarding the external environment. Due to the characteristics of their contents, such as non-polluting or non-toxic substances, these bottles can be reused. However, some contents are polluting, toxic, or corrosive, and these bottles cannot be reused. They require proper disposal and cannot be simply thrown away. Currently, these bottles are mainly recycled through incineration. Once incinerated, the entire bottle melts down. Because it contains the contents, this melted material cannot be reused and requires other methods for harmless treatment.

[0003] Every year, the usage of these packaging bottles, such as chemical and pesticide bottles, is enormous. The production of these bottles requires a large amount of material. After all these bottles are incinerated, new materials are needed for production, resulting in these bottles remaining in a one-way, non-recyclable state. This leads to very low material utilization and significant waste. Simultaneously, the pressure on incineration and subsequent treatment is immense; the larger the volume incinerated, the more harmful substances are generated, increasing the difficulty and pressure of treatment, creating a vicious cycle. Therefore, there is an urgent need for a type of packaging bottle that, after use, can be fully recycled and reused as much as possible without polluting the environment, reducing waste and alleviating treatment pressure. Summary of the Invention

[0004] This invention provides a packaging bottle with a detachable inner bag. The inner bag is disposed inside the bottle and is detachable from the inner wall of the bottle. The bottle body protects the inner bag. The combination of the inner bag and the bottle body allows the packaging bottle to be used normally and can store contaminated or harmful contents. If the contents are used up, the inner bag can be separated from the bottle body, and the bottle body can be recycled. The inner bag and residual contents are processed according to normal procedures. This reduces the pressure of processing, improves the recycling rate of materials, reduces costs, and reduces the pressure on the environment.

[0005] This invention provides a packaging bottle recycling and separation device that can separate the inner bag from the inner wall of the bottle inside the bottle, and then separate the bottle body and the inner bag into two independent parts by cutting, thereby realizing the recycling and reuse of the bottle body without affecting the subsequent processing of the inner bag and residual contents.

[0006] The specific technical solution of the present invention is as follows: a packaging bottle with a separable inner bag, comprising a bottle body and a bottle cap that matches the bottle mouth of the bottle body, a separable inner bag being laminated to the inner wall of the bottle body, the opening of the inner bag extending to the inner wall of the bottle mouth; a first component that can be separated from the bottom of the bottle body is provided at the center of the bottom of the bottle body, the inner wall of the first component being fixed to the corresponding part of the inner bag in an inseparable state.

[0007] The inner bag is located inside the bottle and has a composite structure relative to the inner wall of the bottle. This composite structure allows the inner bag to be separated from the inner wall of the bottle. This bonding is usually done with adhesive. The opening of the inner bag extends to the bottle neck, ensuring that the inner bag is an independent structure. This means that the contents of the inner bag will not enter the space between the inner bag and the inner wall of the bottle. Of course, the inner bag has a certain strength to withstand tensile or rotational forces. The inner bag may also have specific requirements depending on the contents, such as corrosion resistance and sealing properties, so that it can hold the required contents. A first component is located at the bottom of the bottle. The first component can be of various shapes, such as round, square, or triangular. The first component is located at the center of the bottom of the bottle and can be separated from the bottom of the bottle. (The last sentence appears to be incomplete and possibly refers to a separate part.) Previously, the first component was an integral part of the bottle bottom. Once separated, the first component would detach from the bottle bottom, requiring external force to ensure it wouldn't separate during normal use. The first component and inner bag were fixed and inseparable, meaning they were an integral part. Even after the first component separated from the bottle bottom, it wouldn't separate from the inner bag. In other words, operating the first component, such as rotating it, would also rotate the inner bag, causing it to separate from the inner wall of the bottle. Once separated, the bottle could be recycled, and the inner bag and any remaining contents could be processed according to normal procedures. This reduced processing pressure, increased material recycling rates, lowered costs, and reduced environmental impact.

[0008] Preferably, a bottom hole is provided at the center of the bottom of the bottle, and the first component blocks the bottom hole; the outer periphery of the first component is connected to the edge of the bottom hole through a radial connecting part, and a groove is formed between the outer periphery of the first component and the edge of the bottom hole. The first component blocks the bottom hole, thereby ensuring the safety of the bottom of the inner bag. This blocking includes a completely sealed state and a connected state with a certain small gap; the completely sealed state can be achieved by using a recessed easy-tear mark, and the connected state with a certain small gap can be achieved by using an intermittent connection method; the connection part used in this application to connect the first component and the bottom hole is equivalent to a connected state with a certain small gap.

[0009] Preferably, the bottom hole is circular, the first component is circular, and the connecting part is short columnar and arranged symmetrically with respect to the bottom of the bottle.

[0010] Preferably, the center of the bottle bottom is recessed inwards, and the area of ​​this recessed area is larger than the area of ​​the first component. This recessed center prevents the first component from protruding from the bottle bottom, providing protection and preventing it from separating from the bottle bottom under normal use due to external forces.

[0011] Preferably, the bottle has tear marks, the outer surface of which is V-shaped. The tear marks facilitate separation of the bottle.

[0012] A recycling and separation device for a packaging bottle with a detachable inner bag includes a frame, a bottle clamping component mounted on the frame for fixing the bottle body, a cutting component mounted on the frame for cutting and separating the bottle body, and a hinge component mounted on the frame for hinged to separate the inner bag from the inner wall of the bottle body.

[0013] The bottle clamping component is used to clamp the bottle, the cutting component cuts the bottle to facilitate recycling after cutting, and the hinge component is used to separate the first component from the bottom of the bottle. At the same time, the first component separates the inner bag from the inner wall of the bottle, so that the inner bag will not be affected when the cutting component cuts and separates the bottle.

[0014] Preferably, a working platform is provided on the frame, a material discharge port is provided on the working platform, and a material discharge chute connected to the material discharge port is provided under the working platform.

[0015] Preferably, the bottle clamping component includes a lower clamping component and an upper clamping component, with a clamping hole between the upper and lower clamping components that matches the shape of the bottle. The upper clamping component is connected to a clamping lifting component. The shape of the clamping hole matches the shape of the bottle, which facilitates clamping the bottle and ensures that the bottle maintains its shape, so that it will not deform during cutting and will not affect the cutting and separation.

[0016] Preferably, the cutting component includes a cutting blade and a cutting lifting component that drives the cutting blade to rise and fall, with the cutting edge of the cutting blade inclined relative to the surface of the working platform.

[0017] Preferably, the hinge component includes a hinge rod with a threaded outer surface, a hinge head fixed to the front end of the hinge rod, and a telescopic component rotatably connected to the rear end of the hinge rod. The hinge rod engages with a rotating sleeve, which limits the rotation of the hinge rod. The end of the hinge head is provided with a mating structure that engages with the outer periphery of the first component. The mating structure at the end of the hinge head engages with the outer periphery of the first component. If the outer periphery of the first component has a small gap connection structure, then this mating structure is equivalent to a tooth shape, with the teeth inserted into the gap and the tooth groove engaging with the connecting component. The hinge rod has a threaded outer surface and engages with the rotating sleeve. As the hinge rod moves axially, it can also rotate. Once the hinge rod rotates, it drives the hinge head at the front end to rotate, allowing the hinge head to separate the first component from the bottom of the bottle. Continued rotation hinges the inner bag together along the axis, separating the inner bag from the inner wall of the bottle. The telescopic component drives the hinge rod to move axially. Considering the rotation of the hinge rod and the axial movement of the telescopic component, a rotating connection part suitable for axial movement without affecting rotation, such as a ball joint connection structure, needs to be provided at the connection between the hinge rod and the telescopic component.

[0018] The beneficial effects of this invention are: 1. A separable inner bag is compositely set on the inner wall of the bottle, so that the inner bag and the bottle can be processed separately. The inner bag is processed according to the nature of the contents, and the bottle can be recycled, which reduces the processing pressure, improves the recycling rate of materials, reduces costs, and reduces the pressure on the environment. 2. A first component is set at the bottom of the bottle. By operating the first component, the inner bag is separated from the inner wall of the bottle, so that the inner bag will not be damaged when the bottle is separated. 3. The first component is operated by a hinge component to achieve automatic separation of the inner bag from the bottle. Attached Figure Description

[0020] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings. Example

[0021] like Figure 1 Figure 2 Figure 3 As shown, a packaging bottle with a detachable inner bag includes a bottle body 1 and a bottle cap 2 that matches the bottle mouth. A detachable inner bag 3 is adhesively bonded to the inner wall of the bottle body, and the opening of the inner bag extends to the inner wall of the bottle mouth. A first component 5, which can be separated from the bottom of the bottle body, is provided at the center of the bottom 4 of the bottle body. The inner wall of the first component is fixed to the corresponding part of the inner bag and is inseparable. In this embodiment, the bottle body is cylindrical, and the part of the bottle body near the bottle mouth is conical.

[0022] The center of the bottom of the bottle is recessed inwards, and the area of ​​this recessed area is larger than the area of ​​the first component. A bottom hole is provided at the center of the bottom of the bottle. The bottom hole is circular, and the first component is circular. The outer periphery of the first component is connected to the edge of the bottom hole by a radial connecting part 7. A groove 6 is formed between the outer periphery of the first component and the edge of the bottom hole. The connecting part is short columnar and is arranged symmetrically with respect to the bottom of the bottle.

[0023] The bottle has easy-tear marks, the outer surface of which is V-shaped and located near the bottle opening.

[0024] like Figure 4 Figure 5 Figure 6 As shown, a recycling and separation device 8 for a packaging bottle with a separable inner bag includes a frame 9, a bottle clamping component mounted on the frame for fixing the bottle body, a cutting component mounted on the frame for cutting and separating the bottle body, and a hinge component mounted on the frame for hinged to separate the inner bag from the inner wall of the bottle body.

[0025] The frame is equipped with a working platform 13, on which the bottle clamping component, cutting component and hinge component are all located. The hinge component is located on the side of the bottle clamping component.

[0026] The working platform is provided with a discharge port 12, and a discharge trough 11 connected to the discharge port is provided under the working platform. The outlet of the discharge trough is connected to a discharge box. The discharge port is located on the side of the bottle clamping component.

[0027] The bottle clamping components include a lower clamping component 20 and an upper clamping component 19. A clamping hole 31, adapted to the shape of the bottle, is formed between the upper and lower clamping components. The upper clamping component is connected to a clamping lifting component 17, which is a lifting cylinder. The clamping lifting component is mounted on a clamping bracket 18, which is shaped like a gate spanning both sides of the upper clamping component. The clamping lifting component is arranged vertically, with its axis aligned with the center of the clamping hole. The ends of the upper and lower clamping components are flush, and the length of the upper clamping component is shorter than that of the lower clamping component.

[0028] The cutting component includes a cutting blade 15 and a cutting lifting component 16 that drives the cutting blade to rise and fall. The cutting lifting component uses a lifting cylinder, and the cutting blade's edge is inclined relative to the working platform surface. A blade holder 30 is provided above the cutting blade, and the blade holder is fixed to the end of the telescopic rod of the cutting lifting component. The cutting lifting component is mounted on a cutting support 14, which is fixed to the working platform. Two vertical guide rods 29 are provided on the cutting surface, and the guide rods are fixed to the blade holder. The vertical axis of the guide rods is parallel to the lifting direction of the cutting lifting component. The cutting blade's blade surface is located near the end of the bottle clamping component.

[0029] The hinge component includes a hinge rod 24 with an external threaded structure, a hinge head 21 fixed to the front end of the hinge rod, and a telescopic component 27 rotatably connected to the rear end of the hinge rod. The hinge rod engages with a rotating sleeve 23, and the rotating sleeve limits the rotation of the hinge rod. A first support 22 is fixed on the working platform, and the rotating sleeve is disposed within the first support. The inner wall of the rotating sleeve has an internal thread, which engages with the external thread of the hinge rod. The first support is located near the other end of the bottle clamping component, and the length of the hinge rod is greater than the depth of the bottle. The end of the hinge head has a mating structure that engages with the outer periphery of the first component. In this embodiment, the hinge head is cylindrical, and a groove 32 is provided on the front end of the hinge head. The groove is spiral-shaped relative to the hinge rod, and its size matches the size of the connecting part on the outer periphery of the first component. The depth of the groove matches the thickness of the bottom of the bottle. The telescopic component uses a telescopic cylinder and is fixed to the working platform by a mounting base 26. The telescopic length of the telescopic component matches the depth of the bottle. The rear end of the hinge rod is connected to the telescopic component via a rotating connection 25. In this embodiment, the rotating connection adopts a ball head structure, including a left connecting component and a right connecting component. The end of the left connecting component is provided with a ball head, and the end of the right connecting component is provided with a cup-shaped head. The ball head and the cup-shaped head cooperate with each other.

[0030] like Figure 7 As shown, after the packaging bottle is used up, the bottle cap separates from the bottle body. Then, the bottle body is placed into the clamping hole of the lower clamping component. Next, the upper clamping component moves down to fix the bottle body. Then, the telescopic component pushes the hinge rod forward, and the end of the hinge head is inserted into the groove on the outer periphery of the first component. The connecting part is inserted into the inclined groove. As the hinge rod extends forward, it rotates due to the limiting position of the rotating sleeve. The hinge rod drives the hinge head to rotate simultaneously. The front end of the hinge head cuts off the connecting part on the outer periphery of the first component and drives the first component to rotate. The first component and the bottom of the inner bag are fixed structures, so the inner bag is driven to hinge along the center line, causing the inner bag to separate from the inner wall of the bottle. The hinge rod continues to extend forward until the first component and the inner bag have passed the position of the cutting blade. At this time, the inner bag and the first component are both inserted into the inside of the bottle mouth. Then the telescopic component drives the hinge rod to retract, causing the hinge rod to separate from the first component. The cutting blade moves downward under the drive of the cutting lifting component, and the blade begins to cut the bottle body until the bottle body is cut into two pieces. One piece, connected to the inner bag, slides down from the discharge port along the discharge chute into the hopper, while the other piece is still in the clamping hole. Then the clamping lifting component is lifted to collect the remaining bottle body.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
