Description
Technical Field
[0001] This utility model belongs to the field of auxiliary devices for press-type bottles, specifically relating to a connection structure between inner and outer bottles. Background Technology
[0002] Currently, daily chemical products are appearing more and more frequently in people's lives. Washing and care products have become deeply integrated into people's lives, making it convenient for them to clean and wash their belongings and bodies. These daily chemical products are generally packaged in pump bottles; when needed, pressing the pump on the top of the bottle dispenses a fixed amount of product. While these products are extremely convenient, they also take up a lot of space. In today's homes where space is at a premium, when these daily chemical products are neatly arranged in the kitchen and bathroom, the space appears cluttered and inconvenient. Since pump bottles are used promptly and there is rarely a dedicated place to store them, fixing them to the wall makes them convenient for people to use. However, replacing the contents of a pump bottle fixed to the wall can be cumbersome after use. If the bottle is designed with a detachable structure, it would be easier to open the cap and replace the contents. Therefore, an inner bottle can be added to the detachable bottle, and the inner bottle can be replaced directly when the contents need to be changed. However, this inner bottle cannot simply be placed inside the bottle for use, as the lack of a fixing structure may cause it to fall off during use, resulting in waste. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a connection structure for inner and outer bottles. By rotating and screwing the fitting post inside the upper bottle into the guide post inside the inner bottle, the locking groove is fitted into the locking post when over-rotated, thereby achieving a stable connection between the upper bottle and the inner bottle. This keeps the first bottle opening and the second bottle opening of the inner bottle coaxial and the upper end face flush, which facilitates the stable connection of the subsequent pressing bottle.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A connection structure for inner and outer bottles includes an upper bottle, a lower bottle, and an inner bottle. The inner bottle is detachably connected to the upper bottle. The first opening at the upper end of the inner bottle extends into the second opening at the upper end of the upper bottle. The lower bottle fits onto the outer wall of the inner bottle from bottom to top. The upper end of the lower bottle is detachably connected to the lower end of the upper bottle.
[0006] A guide post is provided on the outer side wall of the first bottle opening, and a fitting post is provided on the inner side wall of the second bottle opening. During the connection between the inner bottle and the upper bottle, the upper end face of the fitting post abuts against the lower end face of the guide post. The end of the guide post is connected to a locking post that is vertically downward and connected to the inner bottle. The fitting post is provided with a locking groove, and the locking post and the locking groove are connected in an abutting manner. The guide post is spiraled downward on the outer side wall of the first bottle opening and connected to the locking post. The spiral direction of the fitting post matches the spiral direction of the guide post.
[0007] The inner and outer bottle connection structure employs this design. To ensure a stable connection of the inner bottle, it is first detachably connected to the upper bottle, with the first opening at the top of the inner bottle extending into the second opening at the top of the upper bottle. More preferably, the axes of the first and second openings coincide, and the upper surfaces of the first and second openings are flush. After connecting the upper and inner bottles, the lower bottle is then fitted onto the outer wall of the inner bottle from bottom to top, with its upper end detachably connected to the lower end of the upper bottle. In this structure, the external threads on the upper outer wall of the upper bottle can engage with the internal threads of the connecting cap on the press bottle. Furthermore, after tightening, the inner bottle remains centered on the connecting cap of the press bottle. Therefore, when using this press bottle to pump daily chemical products from the inner bottle, a more stable effect is achieved, extending the lifespan of the press bottle. Since the pumping principle of the press bottle and the connection method between the press bottle and the upper bottle are existing technologies, they will not be elaborated upon further here.
[0008] To secure the inner bottle within the upper bottle, a spirally downward-pointing guide post is provided on the outer wall of the first bottle opening. The lower end of the guide post connects to a locking post, which abuts vertically downward against the inner bottle. A fitting post, with a locking groove, is provided on the inner wall of the second bottle opening, following the same spiral direction as the guide post. Therefore, to secure the inner bottle within the upper bottle, the second bottle opening is first fitted over the first bottle opening. Then, the upper bottle is rotated along the same spiral direction as the guide post, causing the upper surface of the fitting post to abut against the lower surface of the guide post. As the bottle spirals downward, the fitting post gradually approaches the locking post. Since the locking groove is located near the lower end of the fitting post, the upper bottle stops rotating when the lower end of the fitting post abuts against the locking post. Because the upper bottle is made of plastic... Because of its material composition, the upper bottle has a certain degree of deformation capability. When a rotational force is applied to the upper bottle, the locking post will pass over the interlocking post and embed into the locking groove. Therefore, the locking post will be limited by the locking groove and stop rotating. At this time, the upper bottle and the inner bottle also remain relatively stationary. After the upper bottle and the inner bottle are locked together, the lower bottle is then fitted onto the inner bottle. The lower bottle is then connected to the lower end of the lower bottle by a snap-fit mechanism. Therefore, the only exposed part of the inner bottle is the first bottle opening, which is flush with the second bottle opening. With the obstruction of the upper and lower bottles, no external force can act on the body of the inner bottle. In other words, it is difficult to disengage the locking post from the locking groove by applying external force only from the first bottle opening. This ensures that the inner bottle will not easily detach during normal use, thus ensuring that the press bottle installed on it can be used smoothly and stably.
[0009] Furthermore, the guide posts and locking posts comprise two sets, with the two sets of guide posts and locking posts being symmetrically positioned opposite each other at the first bottle opening with the inner bottle as the center of symmetry; the fitting posts comprise two sets, with the two sets of fitting posts being symmetrically positioned opposite each other at the second bottle opening with the upper bottle as the center of symmetry.
[0010] Compared with the prior art, the advantages of this utility model are as follows: by twisting the upper bottle, the fitting post on the second bottle opening of the upper bottle is made to spiral downward along the guide post on the first bottle opening of the inner bottle until it abuts the locking post. Under continuous external force, the locking post will pass over the fitting post and embed into the locking groove, keeping the upper bottle and the inner bottle in a relatively static state. Then, the lower bottle is fitted onto the inner bottle and connected to the upper bottle. At this time, the inner bottle can be protected by the upper and lower bottles, isolating the external environment from directly acting on the bottle body of the inner bottle. It is difficult to disengage the locking post from the locking groove by applying external force only from the first bottle opening. Therefore, it can be ensured that the inner bottle will not easily fall off during normal use, thus ensuring that the press bottle installed on it can be used smoothly and stably.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:
[0020] like Figure 1-5 As shown, a connection structure for inner and outer bottles includes an upper bottle 1, a lower bottle 2, and an inner bottle 3. The inner bottle 3 is detachably connected to the upper bottle 1. The first bottle opening 31 at the upper end of the inner bottle 3 extends into the second bottle opening 11 at the upper end of the upper bottle 1. The lower bottle 2 fits onto the outer wall of the inner bottle 3 from bottom to top. The upper end of the lower bottle 2 is detachably connected to the lower end of the upper bottle 1.
[0021] A guide post 32 is provided on the outer side wall of the first bottle opening 31, and a fitting post 12 is provided on the inner side wall of the second bottle opening 11. During the connection between the inner bottle 3 and the upper bottle 1, the upper end face of the fitting post 12 abuts against the lower end face of the guide post 32. The end of the guide post 32 is connected to a locking post 33 that is vertically downward connected to the inner bottle 3. The fitting post 12 is provided with a locking groove 13, and the locking post 33 and the locking groove 13 are connected in an abutting manner. The guide post 32 is spiraled downward on the outer side wall of the first bottle opening 31 and connected to the locking post 33. The spiral direction of the fitting post 12 matches the spiral direction of the guide post 32.
[0022] Furthermore, the guide post 32 and the locking post 33 include two sets, and the two sets of guide posts 32 and locking posts 33 are symmetrical about the inner bottle 3 as the center of symmetry on the first bottle opening 31; the fitting post 12 includes two sets, and the two sets of fitting posts 12 are symmetrical about the upper bottle 1 as the center of symmetry inside the second bottle opening 11.
[0023] Description of the working principle of this utility model:
[0024] In this connection structure for the inner and outer bottles, to achieve a stable connection of the inner bottle 3, the inner bottle 3 is first detachably connected to the upper bottle 1, such that the first opening 31 at the upper end of the inner bottle 3 extends into the second opening 11 at the upper end of the upper bottle 1. More preferably, the axes of the first opening 31 and the second opening 11 coincide, and the upper surface of the first opening 31 is flush with the upper surface of the second opening 11. After completing the connection between the upper bottle 1 and the inner bottle 3, the lower bottle 2 is then fitted onto the outer wall of the inner bottle 3 from bottom to top, and the upper end of the lower bottle 2 can be... The upper bottle 1 is disassembled and connected to the lower end. In this structure, the external thread on the upper outer wall of the upper bottle 1 can engage with the internal thread of the connecting cap on the press bottle. After the connection is completed, the inner bottle 3 can always be kept in the center of the connecting cap of the press bottle. Therefore, when using the press bottle, pumping daily chemical products from the inner bottle 3 can have a more stable effect and extend the service life of the press bottle. Since the pumping principle of the press bottle and the connection method between the press bottle and the upper bottle 1 are existing technologies, they will not be described in detail here.
[0025] To secure the inner bottle 3 within the upper bottle 1, a spirally downward-pointing guide post 32 is provided on the outer wall of the first bottle opening 31. The lower end of the guide post 32 connects to a locking post 33, which abuts vertically downward against the inner bottle 3. A locking post 12, with the same spiral direction as the guide post 32, is provided on the inner wall of the second bottle opening 11. The locking post 12 has a locking groove 13. Therefore, during the process of securing the inner bottle 3 within the upper bottle 1, the first... The second bottle neck 11 is fitted onto the first bottle neck 31. The upper bottle 1 is then rotated along the same spiral direction as the interlocking post 12 and the guide post 32, causing the upper end face of the interlocking post 12 to abut against the lower end face of the guide post 32. As the spiral proceeds downwards, the interlocking post 12 gradually approaches the locking post 33. Since the locking groove 13 is located near the lower end of the interlocking post 12, the upper bottle 1 will stop rotating when the lower end of the interlocking post 12 abuts against the locking post 33. Since the upper bottle 1 is made of plastic, it has a certain deformation capacity. When the rotational force is applied to the upper bottle 1, the locking post 33 will pass over the interlocking post 12 and embed into the locking groove 13. Therefore, the locking post 33 will be limited by the locking groove 13 and stop rotating. At this time, the upper bottle 1 and the inner bottle 3 also remain relatively stationary. After the upper bottle 1 and the inner bottle 3 are locked together, the lower bottle 2 is then fitted onto the inner bottle 3. The lower bottle 2 is then connected to the lower end of the lower bottle 2 by a snap-fit. Therefore, the only exposed part of the inner bottle 3 is the first bottle opening 31, which is flush with the second bottle opening 11. With the obstruction of the upper bottle 1 and the lower bottle 2, no external force can act on the body of the inner bottle 3. That is to say, it is difficult to remove the locking post 33 from the locking groove 13 by applying external force only from the first bottle opening 31. Therefore, it can be ensured that the inner bottle 3 will not easily fall off during normal use, thus ensuring that the press bottle installed on it can be used smoothly and stably.
[0026] Because a single set of guide posts 32, locking posts 33, and fitting posts 12 cannot guarantee that the first bottle opening 31 and the second bottle opening 11 will maintain axial alignment during the screwing process, they are more likely to be in an eccentric state. In order to achieve the effect of axial alignment, two sets of guide posts 32, locking posts 33, and fitting posts 12 are set. The two sets of guide posts 32 and locking posts 33 are symmetrical about the first bottle opening 31 with the inner bottle 3 as the center of symmetry, and the two sets of fitting posts 12 are symmetrical about the second bottle opening 11 with the upper bottle 1 as the center of symmetry. Therefore, when the screwing is completed, it can be ensured that the first bottle opening 31 and the second bottle opening 11 can maintain axial alignment.
[0027] The beneficial effects of this utility model are as follows: by twisting the upper bottle 1, the fitting post 12 on the second bottle mouth 11 of the upper bottle 1 is made to spiral downward along the guide post 32 on the first bottle mouth 31 of the inner bottle 3 until it reaches the locking post 33. Under the continuous application of external force, the locking post 33 will pass over the fitting post 12 and embed into the locking groove 13, keeping the upper bottle 1 and the inner bottle 3 in a relatively static state. Then, the lower bottle 2 is fitted onto the inner bottle 3 and connected to the upper bottle 1. At this time, the inner bottle 3 can be protected by the upper bottle 1 and the lower bottle 2, isolating the external environment from directly acting on the bottle body of the inner bottle 3. It is difficult to disengage the locking post 33 from the locking groove 13 by applying external force only from the first bottle mouth 31. Therefore, it can be ensured that the inner bottle 3 will not easily fall off during normal use, thereby ensuring that the press bottle installed on it can be used smoothly and stably.
