Description

Technical Field

[0001] The utility model relates to the technical field of skin care product packaging, in particular to a skin care product tube. Background Art

[0002] Currently, some cream-like skin care products (such as hand creams and hand gels) are typically packaged and used in a flexible tube package. The flexible tube comprises a flexible tube body, a nozzle disposed on the tube body, and a bottle cap that fits over the nozzle. When used, the hand cream or hand gel is squeezed out of the nozzle by squeezing the flexible tube body. However, after each use, a certain amount of hand cream or hand gel remains in the nozzle. When the bottle cap is closed, the remaining amount of hand cream or hand gel is contaminated on the inner top wall of the bottle cap, making it difficult to clean. Furthermore, this area is frequently exposed to air, which can lead to bacterial growth. Furthermore, for ease of use, users often carry the flexible tube used to store the hand cream or hand gel in a handbag to accommodate their on-the-go use. However, the tube body is easily bumped and shaken against other items in the handbag, causing the bottle cap to loosen. Furthermore, the soft tube body is easily squeezed by external objects, causing more hand cream or hand gel remaining in the nozzle to enter the gap between the loosened bottle cap and the nozzle. Utility Model Content

[0003] The purpose of the utility model is to provide a skin care product tube, which is used to solve the problem that the hose used to package cream skin care products in the prior art has poor sealing performance and is prone to skin care product residue at the tube mouth, causing the skin care product to be contaminated on the bottle cap and difficult to clean.

[0004] In order to achieve the above objectives, the present invention provides a skin care product tube, comprising:

[0005] A tube body, wherein the upper end of the tube body has an upwardly protruding connecting tube, and an output hole communicating with the tube body is provided along the axial direction of the connecting tube; the inner diameter of the output hole gradually decreases from top to bottom;

[0006] a cover body, threadedly assembled on the outer peripheral wall of the connecting pipe; and

[0007] A push plate, a downwardly extending connecting column is connected to the inside of the cover body, the push plate is connected to the end of the connecting column, and the edge of the push plate is provided with an elastic portion that matches the inner side of the output tube; the cover body is screwed to move the push plate downward along the axial direction of the output hole, and the elastic portion is compressed and fits against the inner wall of the output hole.

[0008] In some embodiments of the present application, a closed locking groove is provided on the inner wall of the output hole, so that when the push plate moves to the locking groove, the elastic part is reset and locked in the locking groove.

[0009] In some embodiments of the present application, the elastic portion is a rubber ring that is fittedly connected to the outer peripheral wall of the pushing plate.

[0010] In some embodiments of the present application, the pushing plate is arranged inside the cover body.

[0011] In some embodiments of the present application, the connecting column is detachably connected to the top wall of the inner cavity of the cover body.

[0012] In some embodiments of the present application, the upper end surface of the cover body is provided with a concave hole, and the bottom wall of the concave hole has a first limiting groove and a second limiting groove arranged in a cross shape, and the second limiting groove is provided along the axial direction of the cover body;

[0013] The upper end of the connecting column is connected to a stop plate that can pass through the second limiting groove along the axial direction of the cover body, and the size of the stop plate is matched with the size of the first limiting groove;

[0014] A pressing piece for pressing against the upper end surface of the stop plate is detachably provided in the concave hole.

[0015] In some embodiments of the present application, the pressing member includes a pressing column threadedly assembled with the inner wall of the recessed hole, and the pressing column forms a pressing surface facing a side of the stop plate for pressing against the stop plate.

[0016] In some embodiments of the present application, the outer peripheral wall of the pressure column is provided with a first threaded portion, and the inner wall of the recessed hole is provided with a second threaded portion that cooperates with the first threaded portion.

[0017] In some embodiments of the present application, a side wall of the locking groove facing the tube body has an inverted tapered portion inclined from top to bottom, and the inverted tapered portion extends axially toward the output hole.

[0018] The skin care product tube of the embodiment of the present invention has the following advantages compared with the prior art: the push plate is connected to the cover body and the outer periphery of the push plate has an elastic part. When the cover body is screwed on the connecting tube, the push plate is driven to move along the axial direction of the output hole in the output hole, and the elastic part is compressed and fits the inner wall of the output hole, thereby pushing the paste skin care product remaining in the output hole back into the tube body, thereby scraping off the paste skin care product remaining in the connecting tube, and effectively avoiding the contact between the paste skin care product remaining in the connecting tube and the inner top wall of the cover body, which makes it difficult to clean; because the elastic part is compressed and fits the inner wall of the output hole, the friction resistance of the push plate relative to the output hole is also increased to a certain extent, thereby making the cover body more firmly connected to the tube body. When the skin care product tube is placed in a handbag, loosening between the cover body and the tube body can be effectively avoided, thereby avoiding leakage of the skin care product in the tube body.

[0032] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0034] like Figures 1-8 As shown, the embodiment of the present application provides a skin care product tube, including a tube body 1, the upper end of the tube body 1 has an upwardly protruding connecting tube 11, and an output hole 111 communicating with the tube body 1 is provided along the axial direction of the connecting tube 11; the inner diameter of the output hole 111 gradually decreases from top to bottom, so as to form a large diameter end 1111 at the upper end of the output hole 111 and a small diameter end 1112 at the lower end of the output hole 111; the cover body 2 includes a sealing end 21 and a connecting end 22 connected to the bottom of the sealing end 21, and the connecting end 22 is threadedly assembled on the outer peripheral wall of the connecting tube 11; Figure 6 、 Figure 7 As shown, the outer peripheral wall of the connecting tube 11 is provided with a third threaded portion 112, and the inner wall of the connecting end 22 is provided with a fourth threaded portion 221 that cooperates with the third threaded portion 112, so that the connecting end 22 is threadedly assembled on the connecting tube 11; the pushing plate 3 is connected to the inner side of the cover body 2 with a downwardly extending connecting column 33, and the pushing plate 3 is connected to the end of the connecting column 33. An elastic portion matching the inner wall of the output hole 111 is provided at the edge of the pushing plate 3, and the outer diameter of the elastic portion is the same as the inner diameter of the large diameter end 1111. When the pushing plate 3 moves from the large diameter end 1111 to the small diameter end 1112, the elastic portion provided on the outer periphery of the pushing plate 3 is squeezed by the inner wall of the output hole 111 and produces compression deformation.

[0035] After the user has finished using the product, there is still a lot of creamy skin care product left in the output hole 111. The user then rotates the connecting end 22 of the cover body 2 to the connecting tube 11 (the pushing plate 3 is also aligned with the output hole 111) and screws the cover body 2 downward to move the cover body 2 toward the tube body 1, and finally makes the cover body 2 threadedly assembled on the outer wall of the connecting tube 11; in the process of screwing the cover body 2, the pushing plate 3 connected to the sealing end 21 moves synchronously with the cover body 2 in the output hole 111. Due to the elastic part The outer diameter is the same as the inner diameter of the large diameter end 1111 of the output hole 111. Therefore, when the pushing plate 3 moves toward the tube body 1 in the output hole 111 along with the cover body 2, the elastic part abutting against the inner wall of the output hole 111 synchronously pushes the cream skin care product remaining in the output hole 111 back into the tube body 1, avoiding a large amount of cream skin care product remaining in the output hole 111, and effectively avoiding the cream skin care product remaining in the output hole 111 from contacting the inner top wall of the cover body 2 and making it difficult to clean.

[0036] In some embodiments of the present application, a closed locking groove 4 is provided on the inner wall of the output hole 111, and the height of the locking groove 4 along the axial direction of the output hole 111 is greater than or equal to the height of the elastic part along the axial direction of the output hole 111, so that when the push plate 3 moves to the position of the locking groove 4, the elastic part can be reset and snapped into the locking groove 4, so as to achieve locking positioning of the push plate 3.

[0037] As the cover 2 moves toward the tube body 1, the push plate 3 gradually moves from the large diameter end 1111 to the small diameter end 1112. At this time, the elastic portion provided on the outer periphery of the push plate 3 is squeezed by the inner wall of the output hole 111, thereby generating compression deformation. The compression deformation of the elastic portion increases synchronously with the increase in the downward movement distance of the push plate 3, so that when the cover 2 is installed in place (such as Figure 2 As shown, the sealing end 21 of the cover body 2 is pressed against the upper end surface of the connecting tube 11), and the elastic part just moves to the position corresponding to the locking groove 4. At this time, the elastic part is no longer squeezed by the inner wall of the output hole 111, and the outer peripheral wall of the elastic part that is compressed and deformed due to being squeezed is reset and snapped into the locking groove 4. The top wall of the locking groove 4 forms a non-return portion 41 for pressing against the elastic part, thereby realizing the positioning of the push plate 3 relative to the connecting tube 11. Since the push plate 3 is connected to the sealing end 21 via the connecting column 33, it is also equivalent to achieving the positioning effect of the cover body 2 relative to the tube body 1. When the skin care product tube is placed in a handbag, even if it collides or shakes with other items, the cover body 2 can be more firmly connected to the connecting tube 11 to avoid loosening, thereby greatly improving the sealing effect of the skin care product tube.

[0038] In some embodiments of the present application, Figure 3 、 Figure 5As shown, the elastic portion is a rubber ring 32 that fits and connects to the outer peripheral wall of the push plate 3; when the cover body 2 is gradually screwed onto the connecting tube 11, the push plate 3 and the rubber ring 32 are simultaneously driven to move in the output hole 111, and the outer wall of the rubber ring 32 is abutted against the inner wall of the output hole 111. As the cover body 2 continues to move downward, the extrusion force on the rubber ring 32 from the inner wall of the output hole 111 gradually increases, and the extrusion deformation of the rubber ring 32 also gradually increases. The push plate 3 and the rubber ring 32 During the movement from top to bottom in the output hole 111, the outer wall of the rubber ring 32 always abuts against the inner wall of the output hole 111, thereby pushing the creamy skin care product remaining in the output hole 111 back into the tube body 1; when the cover body 2 is installed in place, the pushing plate 3 just moves to the position corresponding to the locking groove 4. At this time, the rubber ring 32 is no longer squeezed by the inner wall of the output hole 111 and recovers its deformation. During the process of recovering its deformation, the rubber ring 32 gradually enters the locking groove 4 and abuts against the non-return portion 41 (as shown in FIG. Figure 2 、 Figure 3 ), thereby achieving positioning of the push plate 3, and finally achieving locking and positioning of the cover body 2 relative to the tube body 1, effectively preventing the skin care product tube from colliding or shaking with other items in the handbag, causing the cover body 2 to loosen and leading to leakage of the skin care product.

[0039] When the cover 2 needs to be removed from the tube body 1, the cover 2 is twisted in the opposite direction so that the push plate 3 is subjected to an upward force, so that the part of the rubber ring 32 stuck in the locking groove 4 is compressed and deformed again and withdrawn from the locking groove 4. In order to make the rubber ring 32 withdraw from the locking groove 4 better, as shown in FIG. Figure 3 As shown, in this embodiment, the upper end surface of the rubber ring 32 is chamfered along its circumference (forming a chamfered portion 31 on the upper end surface of the rubber ring 32). Simultaneously, the contact area between the check portion 41 and the inner wall of the output hole 111 is also chamfered. When the rubber ring 32 is subjected to a large upward pulling force, the two chamfers guide the rubber ring 32, allowing it to relatively smoothly withdraw from the locking groove 4 and move upward within the output hole 111 along with the push plate 3. At the same time, to ensure that the rubber ring 32 can relatively smoothly enter the output hole 111 from the outside as the cover 2 moves, the lower end surface of the rubber ring 32 is also chamfered along its circumference (forming a chamfered portion 31 on the lower end surface of the rubber ring 32).

[0040] In some embodiments of the present application, since the push plate 3 is in contact with the cream-like skin care product when the cover body 2 is assembled on the tube body 1, the push plate 3 is arranged inside the cover body 2 to prevent the push plate 3 from coming into contact with the ground or other objects when the cover body 2 falls to the ground or other parts due to an accident, and to ensure that the push plate 3 will not be contaminated with foreign debris or dust.

[0041] In some embodiments of the present application, in order to facilitate regular cleaning of the surfaces of the push plate 3 and the rubber ring 32, the connecting column 33 is detachably connected to the sealing end 21. This is because the cover body 2 is often in contact with the air and has a high probability of contact with debris in the external environment, and the lower end surface of the push plate 3 may be attached with creamy skin care products (causing the attached skin care products to easily deteriorate and then breed bacteria). Therefore, the push plate 3 and the rubber ring 32 need to be cleaned regularly; when cleaning is required, the connecting column 33 is removed from the sealing end 21, so that all parts of the push plate 3 and the rubber ring 32 can be thoroughly cleaned.

[0042] In some embodiments of the present application, Figure 5 、 Figure 7 As shown, a concave hole 211 is provided on the upper end surface of the sealing end 21, and the bottom wall of the concave hole 211 has a first limiting groove 212 and a second limiting groove 213 arranged in a cross shape, and the second limiting groove 213 is arranged to pass through the axial direction of the sealing end 21; the upper end of the connecting column 33 is connected to a stop plate 34 that can pass through the second limiting groove 213 along the axial direction of the cover body 2, and the size of the stop plate 34 is matched with the size of the first limiting groove 212 (the size of the first limiting groove 212 is 1 / 4 of the first limiting groove 212). The depth is the same as the height of the stop plate 34. When the stop plate 34 is located in the first limiting groove 212, the upper end surface of the stop plate 34 does not protrude from the first limiting groove 212. A removable pressing member 5 for pressing against the upper end surface of the stop plate 34 is provided in the recessed hole 211. When the stop plate 34 is located in the first limiting groove 212 and the pressing member 5 presses against the upper end surface of the stop plate 34, the stop plate 34 is positioned in the circumferential and axial directions of the recessed hole 211. When the push plate 3 is installed on the sealing end 21 and is positioned, it is in a position such as Figure 2 When the locking plate 34 is completely removed from the second limiting groove 213, the pushing plate 3 can be removed from the cover body 2 and cleaned. The subsequent installation is the reverse process of the above operation.

[0043] In some embodiments of the present application, Figure 6As shown, the pressing member 5 includes a pressing column 51 threadedly assembled with the inner wall of the recessed hole 211, and the pressing column 51 forms a pressing surface 53 facing the side of the stop plate 34 for pressing against the stop plate 34. When the pressing column 51 is threadedly assembled in the recessed hole 211, the pressing surface 53 presses against the bottom wall of the recessed hole 211. Since the stop plate 34 is flush with the bottom wall of the recessed hole 211, the stop plate 34 is positioned axially along the recessed hole 211.

[0044] In some embodiments of the present application, Figure 5 、 Figure 6 As shown, the outer peripheral wall of the pressure column 51 is provided with a first threaded portion 52, and the inner wall of the recessed hole 211 is provided with a second threaded portion 214 that cooperates with the first threaded portion 52, which is used to thread the pressure column 51 into the recessed hole 211; the pressure column 51 is arranged in a stepped shape, and the first threaded portion 52 is provided at the smaller end of the pressure column 51, and the larger end is used to hold and screw the pressure column 51.

[0045] In some embodiments of the present application, Figure 2 、 Figure 3 、 Figure 4 As shown, the locking groove 4 has an inverted tapered portion 42 on the side facing the tube body 1, which is inclined from top to bottom and extends axially toward the output hole 111. The setting of the inverted tapered portion 42 allows the paste-like skin care product originally in the locking groove 4 to better leave the locking groove 4 when the elastic portion moves to the position corresponding to the locking groove 4 and is snapped into the locking groove 4. The paste-like skin care product originally in the locking groove 4 enters the output hole 111 from the locking groove 4 under the guidance of the inverted tapered portion 42, so that the elastic portion can be snapped into the locking groove 4.

[0046] The working process of the present invention is as follows: align the connecting end 22 of the cover body 2 with the connecting tube 11 and screw the cover body 2 downward so that the cover body 2 is threadedly assembled on the outer peripheral wall of the connecting tube 11. During the process of screwing the cover body 2 downward, the pushing plate 3 and the elastic part are synchronously driven to move from the large diameter end 1111 to the small diameter end 1112 in the output hole 111, and the creamy skin care product remaining in the output hole 111 is pushed back out of the output hole 111 by the elastic part abutting against the inner wall of the output hole 111. to the tube body 1, thereby preventing a large amount of cream skin care product from remaining in the output hole 111 and preventing the inner top wall of the cover body 2 from being contaminated with the cream skin care product; when the cover body 2 is installed in place, the elastic part is snapped into the locking groove 4, and under the action of the non-return part 41, the elastic part snapped into the locking groove 4 is positioned, thereby realizing the positioning of the cover body 2 relative to the connecting tube 11, thereby ensuring that the skin care product tube will not become loose when it is placed in a handbag and collides or shakes with other objects.

[0047] In summary, the embodiment of the present invention provides a skin care product tube, which is provided with a push plate 3 connected to the cover body 2 and a rubber ring 32 installed on the outer peripheral wall of the push plate 3 to simultaneously push the paste skin care product (hand cream or hand gel, etc.) remaining in the output hole 111 back into the tube body 1 when the cover body 2 is assembled on the connecting tube 11; at the same time, the inner diameter of the output hole 111 is set to be larger at the top and smaller at the bottom, and a locking groove 4 for positioning the push plate 3 is provided on the inner wall of the output hole 111 near one end of the tube body 1, so as to achieve the effect of positioning the cover body 2 relative to the tube body 1. When the skin care product tube is placed in a handbag, looseness between the cover body 2 and the tube body 1 can be effectively avoided, thereby avoiding leakage of skin care products in the tube body 1; and the push plate 3 in this solution is detachable and installed relative to the cover body 2, so that it is convenient to clean it regularly to ensure the cleanliness of the internal environment of the tube body 1.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
