TECHNICAL FIELD

[0001] The present application relates to the field of cosmetic packaging containers, and, in particular, to a dual-headed tubular cosmetic container. BACKGROUND ART

[0002] A tubular cosmetic container is a common type of cosmetic packaging containers, usually designed as a tubular shape. When in use, a user can open a cover, take out the product to be applied from the container, and apply it through an opening at the top of the container or a brush body fixed inside the cover. Tubular cosmetic applicators are usually used to package a lip gloss, an eyeliner and other products, so that the user can accurately control the application process, while maintaining the hygiene and portability of products.

[0003] However, due to the diversity of cosmetics, some cosmetics need to be used in combination with each other, such as eyelash glue and eyelash reinforcement solution, so that the adhesion and durability of the eyelash glue can be improved. Therefore, a user often needs to purchase a plurality of tubes of different cosmetics and use them in combination with each other. However, when there are many types of cosmetics purchased, it is necessary to separately find out two tubes of cosmetics that match each other for use, resulting in various problems such as cumbersome use, inconvenient carrying, and easy loss.

[0004] Therefore, there is an urgent need to provide a container that can accommodate a plurality of types of cosmetics simultaneously. SUMMARY

[0052] The following is a further detailed explanation of the present application in conjunction with FIGs. 1-8.

[0053] Embodiments of the present application disclose a dual-headed tubular cosmetic container. Embodiment 1 10054] Referring to FIG. 1, a dual-headed tubular cosmetic container made of plastic material includes a connecting sleeve 1, a cover 2, a bottle body 3, and an outer sleeve 4.

[0055] Referring to FIGs. 1 and 2, the connecting sleeve 1 has a circular tubular structure, and a cylindrical receiving groove 11 is formed at both ends of the connecting sleeve 1, respectively. The receiving grooves 11 are arranged along an axis direction of the connecting sleeve 1. Preferably, the receiving groove 11 can be coaxial with the connecting sleeve 1. A partition plate 12 is formed between the two receiving grooves 11 of the connecting sleeve 1 for isolation. In other embodiments of the present application, the partition plate 12 can also be omitted, so that adjacent ends of the two receiving grooves 11 are in communication with each other.

[0056] Referring to FIGs. 1 and 2, there are two covers 2. Both of the covers 2 are of cylindrical shape, with a ring groove formed inside and an opening at one end. The cover 2 has a same diameter as that of the receiving groove 11, and a axial length smaller than that of receiving groove 11, in order to facilitate the fitting of cover 2 with receiving groove 11. When in use, the two covers 2 are inserted and fixed into the receiving grooves 11 of the connecting sleeve 1.

[0057] Referring to FIGs. 1 and 2, further, in order to improve the tightness of the connection 8 between the cover 2 and the receiving groove 11 and prevent the cover 2 from moving relative to the receiving groove 11, the cover 2 and the receiving groove 11 can be fixed by adhesive, or the diameter of the cover 2 or the receiving groove 11 can be changed for achieving interference fixation, or the cover 2 can be in snap connection with the receiving groove 11..

[0058] In addition, this embodiment also provides a specific example in which the cover 2 is in snap connection with the receiving groove 11, as described below.

[0059] Referring to FIGs. 2 and 3, a first insertion strip 111 is formed along an axis direction on a peripheral wall of the receiving groove 11, and a first slot 21 is defined in an outer peripheral wall of the cover 2 along an axis thereof. The first slot 21 extends to one end of the cover 2 away from the opening of the cover 2, and is kept open at that end. When inserting cover 2 into the receiving groove 11, the cooperation between the first slot 21 and the first insertion strip 111 can, on one hand, achieve inserting and guiding for the cover 2, and, on the other hand, after inserting cover 2 into the receiving groove 11, prevent the cover 2 from rotating relative to the receiving groove 11, achieving circumferential fixation between cover 2 and the receiving groove 11.

[0060] Referring to FIGs. 2 and 3, in order to facilitate inserting the first insertion strip 111 into the first slot 21, an arc-shaped first guide portion 112 is formed at one end of a first insertion strip 111 departing from a bottom surface of the receiving groove 11, while the open end of the first slot 21 are expanded on both sides to form a trumpet-shaped first fitting portion 211. In this way, when inserting the cover 2 into the receiving groove 11, the first guide portion 112 of the first insertion strip 111 and the first fitting portion 211 of the first slot 21 can facilitate the insertion fitting of the first insertion strip 111 with the first slot 21.

[0061] Referring to FIGs. 2 and 3, a first ring groove 113 is formed near the opening of the receiving groove 11. The first ring groove 113 is coaxial with the receiving groove 11, and a first snap ring 22 is formed at an end of the outer wall of the cover 2 near the opening. After inserting the cover 2 into the receiving groove 11, the first snap ring 22 can be snapped in a snap-in groove, so that the cover 2 cannot be moved axially relative to the receiving groove 11, achieving axial 9 fixation between the cover 2 and the receiving groove 11.

[0062] Referring to FIGs. 2 and 3, in order to facilitate inserting the first snap ring 22 into the first ring groove 113, the open end of the receiving groove 11 is defined with a first guide slope 114, and a second guide slope 221 is formed on a first side of the first snap ring 22 departing from the opening of the cover 2. In this way, when inserting the cover 2 into the receiving groove 11, the deformation ability from the material of the cover 2 and the connecting sleeve 1, as well as the cooperation between the first guide slope 114 and the second guide slope 221, can fully insert the first snap ring 22 into the first ring groove 113 when pushing the cover 2 into the receiving groove 11, so as to complete a complete fitting between the cover 2 and the receiving groove 11.

[0063] Referring to FIGs. 2 and 3, in summary, after inserting the cover 2 into the receiving groove 11, the insertion fixing of the cover 2 in the receiving groove 11 of the connecting sleeve 1 can be achieved by limiting an axial movement of the cover 2 relative to the receiving groove 11 and a circumferential movement of the cover 2 relative to the receiving groove 11.

[0064] In addition, in other embodiments of the present application, the first slot 21 and the first snap ring 22 can also be formed on the peripheral wall of the receiving groove 11, while the first insertion strip 111 and the first ring groove 113 can be formed on the outer wall of the cover 2, which can achieve the insertion fixing between the receiving groove 11 and the cover 2.

[0065] Referring to FIG. 2, further, in order to positioning an outer bottom of cover 2 within the receiving groove 11, a plurality of first cushion blocks 13 are formed on a bottom surface of the receiving groove 11, which, on the one hand, can support and limit the bottom of cover 2, and, on the other hand, can create a gap between the outer bottom surface of cover 2 and the bottom surface of receiving groove 11, leaving an air storage space and facilitating the complete insertion of cover 2 into the receiving groove 11.

[0066] Referring to FIGs. 1 and 3, there are two bottle bodies 3 with long cylindrical shape. The bottle body 3 as a whole includes a bottle body portion 31 and a bottle mouth portion 32. One end of the bottle body 3 is tapered to form the bottle mouth portion 32, which is configured to be 10 inserted into the cover 2. To ensure a sealing connection between the bottle mouth portion 32 and the cover 2, in this embodiment, both of the bottle mouth portion 32 and the cover 2 are formed with a thread, so as to achieve a thread connection and fixation between the bottle mouth portion 32 and the cover 2.

[0067] In this way, different cosmetics can be filled into the two bottle bodies 3 to meet different use needs, while reducing the overall number of cosmetic bottles and improving the convenience of use. 10068] Referring to FIG. 3, further, in other embodiments of the present application, a connecting rod 23 is fixed on a bottom surface of the opening side of the cover 2. An end of the connecting rod 23 departing from the cover extends out of the cover 2. In this embodiment, the connecting rod 23 is coaxial with the cover 2. The connecting rod 23 can be connected to a brush head, such as that of an eyelash brush, lip gloss brush, or other makeup brush.

[0069] Furthermore, in order to improve the anti-loosening performance of the bottle mouth portion 32 and the cover 2, and reduce the probability of loosening of the cover from the bottle body 3, the ends of the cover 2 and the bottle mouth portion 31 that are close to each other can be further formed with an insertion part and a snap part, respectively, so that, when the bottle mouth portion 32 is threadedly connected to the cover 2, the snap part can be snapped into the insertion part, and, when a torque applied by the bottle body 3 against the cover 2 is lower than a threshold, the snap part cannot be disengaged from the insertion part.

[0070] In this embodiment, a cover 2 provided with an insertion part and a bottle mouth portion 31 provided with a snap part is taken as an example for the following description.

[0071] Referring to FIGs. 3 and 4, the insertion part includes two protrusions 24 protruding from an end face of the cover 2. A snap-in groove 25 is defined between the two protrusions 24, and a first slope 241 is formed on one side of the two protrusions 24 departing from the snap-in groove 25. The first slope 241 tilts and extends to the end face of the cover 2 in a direction departing from the snap-in groove 25. In addition, a protrusion height of the protrusion 24 on one side along a 11 tightening direction of the bottle mouth portion 32 is larger than the protrusion height of the other protrusion 24, so that the snap block 33 abuts against the other protrusion during tightening, achieving a stable limiting in a final tightened state.

[0072] Referring to FIGs. 3 and 4, the snap part includes a snap block 33 that protrudes from an end face of the bottle mouth portion 31. The snap block 33 is formed with a second slope 331 on one side opposite the tightening direction of the bottle mouth portion 32, and the second slope 331 tilts and extends to the end face of the bottle mouth portion 31.

[0073] Referring to FIGs. 3 and 4, when the bottle body 3 is tightened relative to the cover 2 to a final stage, and the applied torque exceeds a threshold, the snap block 33 can cross a protrusion 24 along the first slope 241 and enter the snap-in groove 25, but is blocked by the other protrusion 24, whereby the thread connection between the cover 2 and the bottle body 3 is achieved, completing the tightening of the cover 2 and the bottle body 3.

[0074] Referring to FIGs. 3 and 4, for loosening the bottle body 3 relative to the cover 2, the snap block 33 can be disengaged from the snap-in groove 25 through the second slope 331 only when the applied torque exceeds the threshold. That is, when the applied torque of the bottle body 3 relative to the cover 2 is lower than the threshold, the snap block 33 cannot be disengaged from the snap-in groove 25. After the protrusion 24 is disengaged from the slot, the bottle body 3 is further rotated to separate the cover 2 from the bottle body 3.

[0075] Referring to FIGs. 3 and 4, in summary, when the cover 2 is threadedly connected to the bottle body 3, the snap block 33 will cross a protrusion 24 and be inserted into the snap-in groove 25. On the one hand, it reminds the user to tighten the cover 2 against the bottle body 3, and on the other hand, the cooperation between the snap-in groove 25 and the snap block 33 can also achieve an anti-loosening effect of the cover 2 against the bottle body 3, avoiding the cover 2 from loosening relative to the bottle body 3.

[0076] Referring to FIGs. 1 and 5, there are two outer sleeves 4, both of which are of a cylindrical tubular shape. One end of the outer sleeve 4 is open and the other end is closed. The 12 two outer sleeves 4 are coaxially sleeved on the outer side of the bottle mouth portion 31 of the two bottle bodies 3.

[0077] Similarly, in order to improve the tightness of connection between the outer sleeve 4 and the bottle body 3 and avoid the movement of the outer sleeve 4 relative to the bottle body 3, the outer sleeve 4 and the bottle body 3 can be fixed by applying a glue, changing the diameter of the bottle body 3 or the outer sleeve 4 to achieve interference fixation, or by a snap connection.

[0078] In particular, an example snap connection for fixing the bottle body 3 and the outer sleeve 4 is described below.

[0079] Referring to FIGs. 3 and 5, a second insertion strip 41 is formed on an inner peripheral wall of the outer sleeve 4 along the axis direction thereof, and a second slot 34 is formed on the outer peripheral wall of the bottle mouth portion 31 along its axis. The second slot 34 extends to one end of the bottle mouth portion 31 departing from the bottle mouth portion 32, and is kept open at that end. When the bottle body portion 31 is inserted into the outer sleeve 4, the cooperation between the second slot 34 and the second insertion strip 41 achieves insertion guiding of the bottle body portion 31. On the other hand, after inserting the bottle body portion 31 into the outer sleeve 4, the bottle body portion 31 is prevent from rotating relative to the outer sleeve 4, achieving circumferential fixation between the bottle body portion 31 and the outer sleeve 4.

[0080] Referring to FIGs. 3 and 5, in order to facilitate inserting the second slot 34 into the second insertion strip 41, an arc-shaped second guide part 411 is formed at one end of the second insertion strip 41 departing from a bottom surface of the outer sleeve 4, while two sides of the open end of the second slot 34 are expanded to form a trumpet-shaped second fitting portion 341. In this way, when the bottle mouth portion 31 is inserted into the outer sleeve 4, the second guide part 411 of the second insertion strip 41 and the second fitting portion 341 of the second slot 34 can facilitate the insertion fitting of the second insertion strip 41 with the second slot 34.

[0081] Referring to FIGs. 3 and 5, a second ring groove 42 is formed near the open end of the outer sleeve 4. The second ring groove 42 is coaxial with the outer sleeve 4, and a second snap 13 ring 35 is formed at one end of the outer wall of the bottle body portion 31 near the bottle mouth portion 32. After inserting the bottle body portion 31 into the outer sleeve 4, the second snap ring 35 can be snap connected to the snap-in groove, so that the bottle body portion 31 cannot move axially relative to the outer sleeve 4, achieving axial fixation between the bottle body portion 31 and the outer sleeve 4.

[0082] Referring to FIGs. 3 and 5, for facilitating inserting the second snap ring 35 into the second ring groove 42, the inner diameter of the open end of the outer sleeve 4 is slightly larger than that of other portions, and a transition slope 43 is formed between the peripheral wall having larger inner diameter of the open end of the outer sleeve 4 and the peripheral wall having smaller inner diameter of the outer sleeve 4. The second ring groove 42 is defined on the inner peripheral wall having smaller diameter of the outer sleeve 4. Similarly, the diameter of the bottle mouth portion 31 near the bottle mouth portion 32 is larger than the diameter of other portions, so that the bottle body 3 can fit into the outer sleeve 4. The second snap ring 35 is formed in a portion having smaller outer diameter of the bottle mouth portion 31.

[0083] Referring to FIGs. 3 and 5, in addition, a third guide slope 351 is formed on a side of the second snap ring 35 departing from the bottle mouth portion 32. In this way, when the bottle body portion 31 is inserted into the outer sleeve 4, the deformation ability of the material of the bottle body portion 31 and the connecting sleeve 1 itself, together with the cooperation between the transition slope 43 and the third guide slope 351, can fully insert the second snap ring 35 into the second ring groove 42 when pushing the bottle body portion 31 into the outer sleeve 4, so as to achieve a complete fitting between the bottle body portion 31 and the outer sleeve 4.

[0084] Referring to FIGs. 3 and 5, in summary, after inserting the bottle mouth portion 31 into the outer sleeve 4, axial movement of the bottle mouth portion 31 relative to the outer sleeve 4 and circumferential movement of the bottle mouth portion 31 relative to the outer sleeve 4 can be limited, and the insertion fixation of the bottle mouth portion 31 in the outer sleeve 4 of the connecting sleeve 1 can be achieved.

[0085] In addition, in other embodiments of the present application, a second slot 34 and a second snap ring 35 can also be formed on the peripheral wall of the outer sleeve 4, while a second insertion strip 41 and a second ring groove 42 can be formed on the outer peripheral wall of the bottle mouth portion 31, which can achieve the insertion fixation between the outer sleeve 4 and the bottle mouth portion 31.

[0086] Referring to FIG. 5, further, in order to position the outer bottom of the bottle body portion 31 within the outer sleeve 4, a bottom surface of the outer sleeve 4 can be protruded to form a plurality of second cushion blocks 44. The plurality of second cushion blocks 44 can support and limit the bottom of the bottle body portion 31, and also create a gap between the outer bottom surface of the bottle body portion 31 and the bottom surface of the outer sleeve 4, leaving an air storage space and facilitating a complete insertion of the bottle body portion 31 into the outer sleeve 4.

[0087] The implementation principle of the dual-headed tubular cosmetic container in this embodiment is as follows. Two bottle bodies 3 can respectively accommodate different cosmetics, meeting the needs of using a plurality of cosmetics at the same time. When in use, a desired cosmetic bottle body 3 is simply selected, a corresponding bottle body 3 is rotated and disengaged, so that the cosmetic therein can be used. Due to a double-layer structure of the outer sleeve 4 and bottle body 3, the bottle body 3 can be protected, and sealing can be improved to reduce the probability of cosmetic failure. Embodiment 2

[0088] A dual-headed tubular cosmetic container differs from Embodiment 1 in that, it is further provided with an interlocking structure, configured to ensure that, after either of the bottle bodies 3 is disengaged from the cover 2, the other bottle body 3 cannot be disengaged from the other cover 2, so that only one of the bottle bodies 3 can be opened for use at one time, avoiding falling out of cosmetics, for example, due to accidental opening of the other bottle body 3. 15

[0089] Referring to FIG. 6, two ends of the connecting sleeve 1 are respectively provided with a L-shaped locking rod 14. One end of the two locking rods 14 is fixed to the connecting sleeve 1, and the other end is a free end. The free ends of the two locking rods 14 facing the end face of the connecting sleeve 1 form a locking hook 141. A push rod 15 is formed at a side of the two locking rods 14 close to the connecting sleeve 1, and two push rods 15 are provided along the axis direction of the connecting sleeve 1. Further, a sliding groove is defined at positions of the connecting sleeve 1 corresponding to the two push rods 15, so that the two push rods 15 can move axially along the connecting sleeve 1 within the two sliding grooves 16. An end of the two push rods 15 departing from the corresponding locking rod 14 also protrudes out of the end face of the connecting sleeve 1 departing from the locking rod.

[0090] Pushing the push rod 15 can drive the free end of the locking rod 14 connected to the push rod 15 to swing in a direction away from the connecting sleeve 1. After releasing the push rod 15, the locking rod 14, due to its own elastic deformation ability, can reversely push the push rod 15 to protrude out of the end face of the connecting sleeve 1.

[0091] Referring to FIG. 7, there is a locking groove 45 defined in the end face of the two outer sleeves 4 abutting against the connecting sleeve 1. When the bottle mouth portion 31 is tightened against the cover 2, the outer sleeve can abut against the connecting sleeve 1, and the locking rod 14 can be inserted into the locking groove 45.

[0092] Referring to FIG. 8, specifically, when two outer sleeves 4 touch both ends of the connecting sleeve 1, both of the outer sleeves 4 can push the push rod 15, causing the locking rod 14 inserted into the locking groove 45 to deform and disengaging the locking hook 141 from the locking groove 45. After one of the outer sleeves 4 disengages from the connecting sleeve 1, the push rod 15 become free, and, due to its elastic deformation ability, the locking rod 14 on the other side of the connecting sleeve 1 can force the locking hook 141 to hook the locking groove 45 of the outer sleeve 4 at the same side, so as to prevent the outer sleeve 4 from disengaging.

[0093] In summary, the advantages of this embodiment lie in that, when both of the outer sleeves 16 4 are not disengaged from the connecting sleeve 1, they can push against the push rod 15 on a corresponding side, so that the locking rod 14 inserted into the outer sleeve 4 on the other side is only inserted into the locking groove 45, whereby, since the locking hook 141 does not hook into the locking groove 45, either of the outer sleeves 4 can be rotated and assembled. Then, after either 5 of the outer sleeves 4 is removed, the push rod 15 on a corresponding side where the is disassembled outer sleeve 4 become free, so that the locking rod 14, due to its elastic deformation ability, can drive the locking hook 141 to hook into the locking groove 45, limiting the rotation of the other outer sleeve 4. In this way, only the outer sleeve 4 at one side can be disassembled for use, while the outer sleeve 4 at the other side can be prevent from loosening for use. 10
