Control mechanism for a material dispensing end of a tubular container

Abstract

The present invention relates to a control mechanism for a material delivery end of a tubular container, and provides for the arrangement of a rotating component and a sealing component on the fitting. When the rotating component rotates relative to the fitting, the sealing component is rotated and also moves up or down on the fitting. When it moves downward, a blocking part engages with a material delivery channel to seal it. When it moves upward, the blocking part disengages from the material delivery channel and opens it. In other words, by arranging the rotating component and the sealing component on the fitting, the material delivery channel of the tubular container is sealed when not in use, thereby effectively preventing the material inside the tubular body from spilling out when the tubular container is not in use.This improves the user experience.

Description

Title of the invention: Control mechanism for a material dispensing end of a tubular container

[0001] The present invention relates to the structure of a tubular package, and more particularly to a control mechanism for a material dispensing end of a tubular container.

[0002] A tubular package is lightweight and convenient to use. Apart from use as food packaging, a tubular package is more commonly used for daily consumer products such as cosmetics, toothpaste, and shoe polish cream.

[0003] In the prior art, a tubular package comprises a tubular body and a cap. The cap is threadedly connected to the tubular body. For example, cosmetic products packaged in a tubular package require the user to twist and open the cap, remove the cap, then squeeze the tubular body to express the cream or lotion located inside, and after use, replace the cap on the tubular body to carry it in a handbag so that it can be used at any time. Since the cap does not truly close the material dispensing hole of the tubular body, the cream or lotion inside the tubular body may be dispensed into the cap under external pressure or pressure from other objects in the handbag. Therefore, the user's experience is poor when opening the cap and using the product again.Additionally, the cream or lotion can actually spill and mix with other items in the handbag, which greatly affects the user experience.

[0004] In view of the above-mentioned disadvantages of 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 from spilling out when the tubular container is left free, thereby improving the user experience.

[0005] To this end, the present invention proposes the following technical solutions:

[0006] Control mechanism for a material dispensing end of a tubular container, characterized in that it comprises a tubular body, a connector formed in one piece with the tubular body, and a cap mounted on the connector, wherein: the connector comprises a first connecting part, a second connecting part and a third connecting part, arranged in sequence from top to bottom along a direction from the connector to the tubular body, a diameter of the first connecting part being smaller than a diameter of the second connecting part, the diameter of the second connecting part being smaller than a diameter of the third connecting part, a material distribution component integrally formed with the first connecting part being positioned inside the first connecting part, a first material distribution hole being provided on the material distribution component, and an upper end surface of the material distribution component having a locking piece, the cap receives the connector and connects to the connector at the third connecting part of the connector, a sealing component and a rotating component are also mounted on the fitting, the sealing component being threadedly connected to the fitting at the first connecting portion of the fitting, a material distribution channel being formed axially through an upper surface and a lower surface of the sealing component, the rotating component being rotatably connected to the fitting at the second connecting portion of the fitting, an auxiliary head component being mounted on the rotating component, a lower portion of the auxiliary head component being mounted inside the rotating component, while an upper portion of the auxiliary head component is exposed outside the rotating component,a receiving hole for receiving an upper portion of the sealing component opening at a lower surface of a lower portion of the auxiliary head component and extending toward the upper portion of the auxiliary head component, the upper portion of the auxiliary head component having a second material delivery hole in communication with the receiving hole and the material delivery channel, a lower portion of the rotatable component being keyed to the sealing component, such that when the rotatable component rotates relative to the connector, the sealing component threadedly connected to the first connecting portion is rotated and thus moves up or down along the first connecting portion, when the sealing component moves downwards the locking piece engages with the material delivery channel and thus blocks the material delivery channel,and when the sealing component moves upwards, the locking part disengages from the material delivery channel and thus opens the material delivery channel.

[0007] Advantageously, a key is arranged axially inside the rotating component and a keyway is provided axially on the sealing component, in correspondence with the key, and when the key is inserted into the keyway, the rotating component is keyed to the sealing component.

[0008] Advantageously, an inner side of a lower portion of the sealing component comprises a projection, correspondingly the first connecting portion of the connector comprises a locking groove at a proximal position relative to the second connecting portion, and when the material delivery channel is sealed, the projection engages with the locking groove.

[0009] Advantageously, an outer side of the lower portion of the auxiliary head component comprises a first flange, an inner upper portion of the rotary component comprises a position limiting platform, the first flange abutting against a lower end surface of the position limiting platform.

[0010] Advantageously, the rotating component comprises an indication marker, the third connecting part or the tubular body comprises an ON sign and an OFF sign, the indication marker pointing to the ON sign indicates that the material delivery channel is open and the indication marker pointing to the OFF sign indicates that the material delivery channel is sealed.

[0011] Advantageously, the blocking piece is arranged on a central position of the material distribution component and the first material distribution hole comprises a plurality of circular holes distributed uniformly on the material distribution component around the blocking piece.

[0012] Advantageously, an annular groove is provided on the second connecting part and, correspondingly, a second flange is provided on an inner lower part of the rotating component, the second flange being disposed inside the annular groove.

[0013] When needing to use the material contained inside the tubular body, the user can open the cap, rotate the rotating component until the indication marker on the rotating component points to the ON sign; during the rotation of the rotating component, the sealing component is also rotated and moves upward on the first connecting part of the fitting, and the locking part is thus disengaged from the material dispensing channel, then the user can press 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 of the second material dispensing hole.

[0014] After use, the user can rotate the rotating component in the reverse direction, so that the indication marker of the rotating component points to the STOP sign, and then the user can replace the cap on the tubular body. During the rotation of the rotating component in this rotation operation, the sealing component is rotated and moves downward, so that the The locking piece engages with the material delivery channel and thus seals the material delivery channel. As a result, the material inside the tubular body cannot spill out when the tubular container is not in use, thus improving the user experience.

[0015] As can be seen, the present invention provides for the arrangement of the rotatable component and the sealing component on the fitting. When the rotatable component rotates relative to the fitting, the sealing component 30 is also rotated and moves up or down on the fitting. When the sealing component moves downward, the locking piece engages with the material delivery channel and thereby seals the material delivery channel. When the sealing component moves upward, the locking piece disengages from the material delivery channel and thereby opens the material delivery channel.In other words, by arranging the rotating component and the sealing component on the fitting, the material delivery channel of the tubular container is sealed when not in use, thereby effectively preventing the material inside the tubular body from spilling out when the tubular container is not in use. The user experience is thus improved.

[0035] First Embodiment

[0036] As shown in Figures 1-4, a control mechanism for a material dispensing end of a tubular container is disclosed, comprising a tubular body 10, a connector 20 integrally formed with the tubular body 10, and a cap 60 mounted on the connector 20.

[0037] The connector 20 comprises a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23, arranged in sequence from top to bottom along a direction from the connector 20 to 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 distribution component 24 integrally formed with the first connecting portion 21 is positioned inside the first connecting portion 21; a first material distribution hole 241 is provided on the material distribution component 24, and an upper end surface of the material distribution component 24 is provided with a locking piece 242. The cap 60 receives the connector 20 and connects to the connector 20 at the third connecting portion 23 of the connector 20.

[0038] A sealing component 30 and a rotatable component 50 are also mounted on the connector 20, the sealing component 30 being threadedly connected to the connector 20 at the first connecting portion 21 of the connector 20; a distribution channel of material 31 is axially formed through an upper surface and a lower surface of the sealing component 30. The rotating component 50 is rotatably connected to the connector 20 at the second connecting portion 22 of the connector 20. An auxiliary head component 40 is mounted on the rotating component 50, a lower portion of the auxiliary head component 40 being mounted inside the rotating component 50, while an upper portion of the auxiliary head component 40 is exposed outside the rotating component 50. A receiving hole 41 for receiving an upper portion of the sealing component 30 opens at a lower surface of a lower portion of the auxiliary head component 40 and extends toward the upper portion of the auxiliary head component 40.The upper portion of the auxiliary head component 40 has a second material distribution hole 42 in communication with the receiving hole 41 and the material distribution channel 31.

[0039] A lower portion of the rotating component 50 is keyed together with the sealing component 30 such that when the rotating component 50 rotates relative to the connector 20, the sealing component 30 threadedly connected to the first connecting portion 21 will be rotated and thus move up or down along the first connecting portion 21. When the sealing component 30 moves downward, the locking piece 242 engages with the material delivery channel 31 and thus locks the material delivery channel 31. When the sealing component 30 moves upward, the locking piece 242 disengages from the material delivery channel 31 and thus opens the material delivery channel 31. More specifically, a key 51 is axially disposed inside the rotating component 50, and a keyway 32 is axially provided on the sealing component 30 in correspondence of the key 51. When the key 51 is inserted into the keyway 32, the rotating component is keyed together with the sealing component 30.

[0040] In this embodiment, an inner side of a lower portion of the sealing component 30 is provided with a protrusion 33. Correspondingly, the first connecting portion 21 of the connector 20 is provided with a locking groove 211 at a proximal position relative to the second connecting portion 22. When the material delivery channel 31 is sealed, the protrusion 33 engages with the locking groove 211. Due to the engagement of the protrusion 33 with the locking groove 211, the connection strength between the sealing component 30 and the connector 20 is increased, such that even if the rotating component 50 is struck by an external object, the sealed material delivery channel 31 will not easily open.

[0041] In this embodiment, the upper portion 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 portion of the auxiliary head component 40 is provided with a first flange 43; an inner upper portion of the rotating component 50 is provided with a position limiting platform 52; the first flange 43 abuts against a lower end surface of the position limiting platform 52. Also, in order to stabilize the connection between the rotating component 50 and the connector 20 and make the connection neat and orderly, an annular groove 221 is provided on the second connection portion 22 and, correspondingly, a second flange 53 is provided at an inner lower portion 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 connector 20, no clearly visible gap is formed between the rotating component 50 and the connector 20, so as to improve the integrity and appearance of the product.

[0042] In order to facilitate the use of the product, the rotating component 50 according to the present embodiment comprises an indication marker 54; the third connecting part 23 or the tubular body 10 comprises an ON sign 231 and an OFF sign 232. When the indication marker 54 points to the ON sign 231, the user is informed that the material delivery channel 31 is open. When the indication marker 54 points to the OFF sign 232, the user is informed that the material delivery channel 31 is sealed.

[0043] Furthermore, the blocking piece 424 is disposed at a central position of the material dispensing component 24, and the first material dispensing hole 241 is positioned on one side of the blocking piece and has an arc shape. When the material dispensing channel 31 is opened, a large amount of material can be dispensed out of the first material dispensing hole.

[0044] As shown in Figures 5 and 6, when needing to use the material contained inside the tubular body 10, the user can open the cap 60, rotate the rotating component 50 until the indication marker 54 on the rotating component 50 points to the ON sign 231; during the rotation of the rotating component 50, the sealing component 30 is also rotated and moves upward on the first connecting part 21 of the connector 20, and the locking piece 242 is thus disengaged from the material dispensing channel 31, then the user can press 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 of the second material dispensing hole 42.

[0045] As shown in Figures 7 and 8, after use, the user can rotate the rotating component 50 in the opposite direction, such that the indication marker 54 of the rotating component 50 points to the STOP sign 232, then the user can replace the cap 60 on the tubular body. During the rotation of the rotating component 50 in this rotation operation, the sealing component 30 is rotated and moves downward, such that the blocking piece 242 engages with the material delivery channel 31 and thus seals the material delivery channel 31. Accordingly, the material inside the tubular body cannot spill out when the tubular container is not in use, thereby improving the user experience. In addition, since the protrusion 33 engages with the locking groove 211 in this state, the bonding strength between the sealing component 30 and the connector 20 is increased, such that even if the rotating component 50 is struck by an external object, the sealed material delivery channel 31 will not be easily opened, thereby further preventing the material in the tubular body from spilling out.

[0046] Second embodiment

[0047] As shown in Figures 9-16, the second embodiment is structurally substantially identical to the first embodiment, and the same structures will not be described repeatedly herein.

[0048] The second embodiment differs from the first embodiment in that the upper portion of the auxiliary head component 40 has a conical shape, which is suitable for products such as an eyeliner, a lip pencil, or other products having similar functions. Of course, the auxiliary head component 40 of the present invention is not limited to the shapes disclosed in the first and second embodiments. In actual production, manufacturers may change the shape of the auxiliary head component 40 according to the specific functions of the products to be manufactured.

[0049] In addition, in this embodiment, the first material dispensing hole 241 comprises a plurality of circular holes uniformly distributed on the material dispensing component 24. In use, when the tubular body 10 is pressed, the material inside the tubular body 10 will be dispensed in a smaller amount compared to the first embodiment, and the material will be dispensed more uniformly compared to the first embodiment.

[0050] In summary, the present invention is characterized by the arrangement of the rotatable component 50 and the sealing component 30 on the connector 20. When the rotatable component 50 rotates relative to the connector 20, the sealing component 30 is also rotated and moves up or down on the connector 20. When the sealing component 30 moves downward, the locking piece 242 engages with the material delivery channel 31 and thereby seals the material delivery channel 31. When the sealing component 30 moves upward, the locking piece 242 disengages from the material delivery channel 31 and opens thus the material distribution channel 31. In other words, by providing the rotating component 50 and the sealing component 30 on the connector 20, the material distribution channel 31 of the tubular container is sealed when not in use, thereby effectively preventing the material inside the tubular body from spilling out when the tubular container is not in use. The user experience is thus improved.

[0051] The above description illustrates only certain embodiments of the present invention and should not be construed as limiting the technical scope of the present invention. Those skilled in the art may make any minor modifications, configurations, or alternative changes to the embodiments described above without departing from the scope of the present invention.
