Description

The present invention relates to the structure of tubular packaging, and more particularly relates to a control mechanism for a material disposing end of a tubular container. Tubular packaging has a light weight and is convenient to use. Apart from food packaging, tubular packaging is more commonly used in daily products such as cosmetics, toothpaste and shoe polishing cream. In the prior art, tubular packaging comprises a tubular body and a cover. The cover is threadedly connected to the tubular body. For instance, cosmetics packaged in tubular packaging requires a user to turn and open the cover, remove the cover, and then squeeze the tubular body to obtain the cream or lotion inside, and after use, place the cover back onto the tubular body for carrying in a handbag so that it can be used anytime. Since the cover does not actually seal the material dispensing hole of the tubular body, the cream or lotion inside the tubular body may be dispensed in the cover upon external pressure or pressure from other objects in the handbag. Accordingly, user’s experience is bad when the user opens the cover and uses the product again. Furthermore, the cream or lotion may actually spill out and mess up with other objects inside the handbag, and this as well affects the user’s experience significantly. In view of the above disadvantages now in the prior art, the present invention provides a control mechanism for a material dispensing end of a tubular container. The present invention can effectively prevent material inside the tubular container to spill out when the tubular container is left idle, thereby improving user’s experience. To achieve the above objects, the present invention provides the following technical solutions: 13 1224 A control mechanism for a material dispensing end of a tubular container, comprising a tubular body, a connecter integrally formed with the tubular body, and a cover fitted onto the connecter; the connecter comprises a first connecting portion, a second connecting portion, and a third connecting portion, sequentially arranged from top to bottom along a direction from the connecter towards the tubular body; a diameter of the first connecting portion is smaller than a diameter of the second connecting portion; the diameter of the second connecting portion is smaller than a diameter of the third connecting portion; a material dispensing component formed integrally with the first connecting portion is positioned inside the first connecting portion; a first material dispensing hole is provided on the material dispensing component, and an upper end surface of the material dispensing component is provided with a blocking piece; the cover houses the connecter, and connects with the connecter at the third connecting portion of the connecter; a sealing component and a rotating component are also fitted onto the connecter, wherein the sealing component is threadedly connected to the connecter at the first connecting portion of the connecter; a material dispensing channel is formed axially through a top surface and a bottom surface of the sealing component; the rotating component is rotatably connected to the connecter at the second connecting portion of the connecter; an auxiliary head component is fitted onto the rotating component, wherein a lower part of the auxiliary head component is fitted inside the rotating component, while an upper part of the auxiliary head component is exposed out of the rotating component; an accommodating hole for accommodating an upper part of the sealing component is opened at a bottom surface of a lower part of the auxiliary head component extending towards the upper part of the auxiliary head component; the upper part of the auxiliary head component is provided with a second material dispensing hole in communication with the accommodating hole and the 13 1224 material dispensing channel; a lower part of the rotating component is key jointed with the sealing component, such that when the rotating component rotates with respect to the connecter, the sealing component threadedly connected to the first connecting portion will be driven to rotate and thus move up or down the first connecting portion; when the sealing component moves downwardly, the blocking piece engages with the material dispensing channel and thus blocks the material dispensing channel; when the sealing component moves upwardly, the blocking piece disengages from the material dispensing channel and thus opens up the material dispensing channel. A key is axially provided inside the rotating component, and a keyway is axially provided on the sealing component corresponding to the key; when the key is inserted into the keyway, the rotating component is key jointed with the sealing component. An inner side of a lower part of the sealing component is provided with a protrusion; correspondingly, the first connecting portion of the connecter is provided with a locking groove at a position proximal to the second connecting portion; when the material dispensing channel is sealed, the protrusion engages with the locking groove. An outer side of the lower part of the auxiliary head component is formed with a first flange; an inner upper part of the rotating component is provide with a position limiting platform; the first flange abuts against a lower end surface of the position limiting platform. The rotating component is provided with a pointer; the third connecting portion or the tubular body is provided with an ON sign and an OFF sign; the pointer pointing at the ON sign indicates that the material dispensing channel is open; the pointer pointing at the OFF sign indicates that the material dispensing channel is sealed. 13 1224 The blocking piece is disposed on a middle position of the material dispensing component; the first material dispensing hole comprises a plurality of circular holes evenly distributed on the material dispensing component around the blocking piece. An annular groove is provided on the second connecting portion, and correspondingly, a second flange is provided at an inner bottom part of the rotating component, and the second flange is disposed inside the annular groove. When it is required to use the material contained inside the tubular body, the user may open the cover, rotate the rotating component until the pointer on the rotating component points at the ON sign; during rotation of the rotating component, the sealing component is also driven to rotate and move upwardly on the first connecting portion of the connecter, and as such, the blocking piece is disengaged from the material dispensing channel, then the user may squeeze the tubular body so that the material inside the tubular body will be dispensed through the first material dispensing hole into the material dispensing channel and then out from the second material dispensing hole. After use, the user may rotate the rotating piece reversely, so that the pointer on the rotating component points at the OFF sign, and then the user may place the cover again on the tubular body, and during rotation of the rotating component in this rotating operation, the sealing component is driven to rotate and move downwardly, such that the blocking piece engages with the material dispensing channel and thus seals the material dispensing channel. Accordingly, the material inside the tubular body is prevented from spilling out when the tubular container is idle, thereby improving user’s experience. As can be seen, the present invention provides the rotating component and the sealing component on the connecter. When the rotating component rotates with respect to the connecter, the sealing component is driven to rotate and move up or down on the 13 1224 connecter as well. When the sealing component moves downwardly, the blocking piece engages with the material dispensing channel and thus seals the material dispensing channel. When the sealing component moves upwardly, the blocking piece disengages from the material dispensing channel and thus opens the material dispensing channel. In other words, by providing the rotating component and the sealing component on the connecter, the material dispensing channel of the tubular container is sealed when idle, thereby effectively preventing the material inside the tubular body from spilling out when the tubular container is not in use. Hence, user’s experience is improved. FIG. 1 is a structurally exploded view of embodiment 1. FIG. 2 is another structurally exploded view of embodiment 1.

Embodiment 1 13 1224 As shown in FIGs. 1-4, a control mechanism for a material dispensing end of a tubular container is disclosed, comprising a tubular body 10, a connecter 20 integrally formed with the tubular body 10, and a cover 60 fitted onto the connecter 20. The connecter 20 comprises a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23, sequentially arranged from top to bottom along a direction from the connecter 20 towards the tubular body 10. A diameter of the first connecting portion 21 is smaller than a diameter of the second connecting portion 22; the diameter of the second connecting portion 22 is smaller than a diameter of the third connecting portion 23. A material dispensing component 24 formed integrally with the first connecting portion 21 is positioned inside the first connecting portion 21; a first material dispensing hole 241 is provided on the material dispensing component 24, and an upper end surface of the material dispensing component 24 is provided with a blocking piece 242. The cover 60 houses the connecter 20, and connects with the connecter 20 at the third connecting portion 23 of the connecter 20. A sealing component 30 and a rotating component 50 are also fitted onto the connecter 20, wherein the sealing component 30 is threadedly connected to the connecter 20 at the first connecting portion 21 of the connecter 20; a material dispensing channel 31 is formed axially through a top surface and a bottom surface of the sealing component 30. The rotating component 50 is rotatably connected to the connecter 20 at the second connecting portion 22 of the connecter 20. An auxiliary head component 40 is fitted onto the rotating component 50, wherein a lower part of the auxiliary head component 40 is fitted inside the rotating component 50, while an upper part of the auxiliary head component 40 is exposed out of the rotating component 50. An accommodating hole 41 for accommodating an upper part of the sealing component 30 is opened at a bottom surface of a lower part of the auxiliary head component 40 13 1224 extending towards the upper part of the auxiliary head component 40. The upper part of the auxiliary head component 40 is provided with a second material dispensing hole 42 in communication with the accommodating hole 41 and the material dispensing channel 31. A lower part of the rotating component 50 is key jointed with the sealing component 30, such that when the rotating component 50 rotates with respect to the connecter 20, the sealing component 30 threadedly connected to the first connecting portion 21 will be driven to rotate and thus move up or down the first connecting portion 21. When the sealing component 30 moves downwardly, the blocking piece 242 engages with the material dispensing channel 31 and thus blocks the material dispensing channel 31. When the sealing component 30 moves upwardly, the blocking piece 242 disengages from the material dispensing channel 31 and thus opens up the material dispensing channel 31. Specifically, a key 51 is axially provided inside the rotating component 50, and a keyway 32 is axially provided on the sealing component 30 corresponding to the key 51. When the key 51 is inserted into the keyway 32, the rotating component is key jointed with the sealing component 30. In this embodiment, an inner side of a lower part of the sealing component 30 is provided with a protrusion 33. Correspondingly, the first connecting portion 21 of the connecter 20 is provided with a locking groove 211 at a position proximal to the second connecting portion 22. When the material dispensing channel 31 is sealed, the protrusion 33 engages with the locking groove 211. Due to the protrusion 33 engaged with the locking groove 211, the connecting strength between the sealing component 30 and the connecter 20 is increased so that even if the rotating component 50 is impacted by an external object, the sealed material dispensing channel 31 will not be easily opened. 13 1224 In this embodiment, the upper part of the auxiliary head component 40 has a dome shape, which facilitates the application of cream or lotion. In order to stabilize the connection between the auxiliary head component 40 and the rotating component 50, an outer side of the lower part of the auxiliary head component 40 is formed with a first flange 43; an inner upper part of the rotating component 50 is provide with a position limiting platform 52; the first flange 43 abuts against a lower end surface of the position limiting platform 52. Similarly, in order to stabilize the connection between the rotating component 50 and the connecter 20 and to make the connection neat and tidy, an annular groove 221 is provided on the second connecting portion 22, and correspondingly, a second flange 53 is provided at an inner bottom part of the rotating component 50, and the second flange 53 is disposed inside the annular groove 221. Accordingly, when the rotating component 50 rotates on the connecter 20, no obviously visible gap is formed between the rotating component 50 and the connecter 20, so as to enhance the integrity and better appearance of the product. In order to facilitate use of the product, the rotating component 50 according to the present embodiment is provided with a pointer 54; the third connecting portion 23 or the tubular body 10 is provided with an ON sign 231 and an OFF sign 232. When the pointer 54 points at the ON sign 231, the user is informed that the material dispensing channel 31 is open. When the pointer 54 points at the OFF sign 232, the user is informed that the material dispensing channel 31 is sealed. Besides, the blocking piece 242 is disposed on a middle position of the material dispensing component 24, and the first material dispensing hole 241 is positioned on a side of the blocking piece and has an arc shape. When the material dispensing channel 31 is open, large amount of material can be dispensed out from the first material dispensing hole. 13 1224 As shown in FIGs. 5-6, when it is required to use the material contained inside the tubular body 10, the user may open the cover 60, rotate the rotating component 50 until the pointer 54 on the rotating component 50 points at the ON sign 231; during rotation of the rotating component 50, the sealing component 30 is also driven to rotate and move upwardly on the first connecting portion 21 of the connecter 2, and as such, the blocking piece 242 is disengaged from the material dispensing channel 31, then the user may squeeze the tubular body 10 so that the material inside the tubular body 10 will be dispensed through the first material dispensing hole 241 into the material dispensing channel 31 and then out from the second material dispensing hole 42. As shown in FIGs. 7-8, after use, the user may rotate the rotating piece 50 reversely, so that the pointer 54 on the rotating component 50 points at the OFF sign 232, and then the user may place the cover 60 again on the tubular body. During rotation of the rotating component 50 in this rotating operation, the sealing component 30 is driven to rotate and move downwardly, such that the blocking piece 242 engages with the material dispensing channel 31 and thus seals the material dispensing channel 31. Accordingly, the material inside the tubular body is prevented from spilling out when the tubular container is idle, thereby improving user’s experience. Furthermore, since the protrusion 33 engages with the locking groove 211 in this condition, the connecting strength between the sealing component 30 and the connecter 20 is increased so that even if the rotating component 50 is impacted by an external object, the sealed material dispensing channel 31 will not be easily opened, thereby further preventing the material in the tubular body from spilling out. Embodiment 2 As shown in FIGs. 9-16, embodiment 2 is structurally largely the same as embodiment 1, and the same structures will not be repeatedly described herein. 13 1224 Embodiment 2 is different from embodiment 1 in that, the upper part of the auxiliary head component 40 has a conical shape, which is suitable for products like eyeliner, lipliner, or other products with similar functions. Of course, the auxiliary head component 40 of the present invention is not limited to the shapes disclosed in embodiment 1 and embodiment 2. In actual production, manufacturers may change the shape of the auxiliary head component 40 based on the specific functions of the products intended to be produced. Further, in this embodiment, the first material dispensing hole 241 comprises a plurality of circular holes evenly distributed on the material dispensing component 24. During use when the tubular body 10 is squeezed, the material inside the tubular body 10 will be dispensed in a smaller amount compared with embodiment 1, and the material will be dispensed more evenly compared with embodiment 1. In summary, the present invention is characterized by providing the rotating component 50 and the sealing component 30 on the connecter 20. When the rotating component 50 rotates with respect to the connecter 20, the sealing component 30 is driven to rotate and move up or down on the connecter 20 as well. When the sealing component 30 moves downwardly, the blocking piece 242 engages with the material dispensing channel 31 and thus seals the material dispensing channel 31. When the sealing component 30 moves upwardly, the blocking piece 242 disengages from the material dispensing channel 31 and thus opens the material dispensing channel 31. In other words, by providing the rotating component 50 and the sealing component 30 on the connecter 20, the material dispensing channel 31 of the tubular container is sealed when idle, thereby effectively preventing the material inside the tubular body from spilling out when the tubular container is not in use. Hence, user’s experience is improved. CM The invention described above only illustrates some embodiments of the present invention, and shall not be construed as limiting to the technical scope of the present invention. Any minor changes, modifications or alternative configurations made to the embodiments described above in accordance with the technical essence of the present invention should also fall within the scope of the present invention. 13 1224
