Description

Technical Field

[0001] This utility model belongs to the field of packaging container technology, and specifically refers to a decorative dispensing packaging hose. Background Technology

[0002] Cosmetic packaging tubes are flexible packaging tubes used for storing and dispensing cosmetics, typically made of plastic or metal. These tubes are designed for easy squeezing, allowing for controlled dosage, and are widely used in the packaging of products such as face creams, facial cleansers, and toothpaste.

[0003] When designing products, for both functional and aesthetic reasons, some products require the discharge ports of the packaging hose to be designed in a radial pattern, evenly distributed around the central axis, to create an effect similar to blooming flower petals when extruding material. However, in actual use, due to factors such as air pressure inside the hose, the discharge effect of each discharge port is not consistent. This is because the release of air pressure may accelerate the material flow of one or several discharge ports, causing them to discharge before the others. In addition, existing packaging hoses may leak material during outdoor carrying due to shaking and squeezing, contaminating the user's backpack. Utility Model Content

[0004] The main purpose of this utility model is to provide a decorative discharge packaging tube to solve the problems existing in the prior art, avoid inconsistent discharge from each discharge hole during extrusion, achieve uniform discharge, and allow free opening and closing to prevent leakage.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A decorative dispensing packaging hose includes a body, an adapter, and a dispensing cap. The body has a dispensing hole on its end face. The adapter is rotatably fitted onto the end of the body, and its end face has a through hole opposite to the dispensing hole. The through hole may or may not connect with the dispensing hole as the adapter rotates. The dispensing cap covers the end face of the adapter and has dispensing holes spaced at equal angles around the axis of the through hole. A dispensing channel is formed between the end face of the body and the opposite face of the dispensing cap, connecting the through hole and the dispensing hole. The dispensing channel has at least one bend between the through hole and the dispensing hole.

[0007] A sealing post is provided on the end face of the main body, and the discharge hole is provided around the sealing post and there is at least one discharge hole; a feed tube is provided at the axial position of the adapter, and the feed hole is provided at the axial position of the feed tube; the adapter is threadedly connected to the main body, and the sealing post seals or opens the inner end of the feed tube as the adapter rotates.

[0008] Preferably, the circumferential surface of the main body is provided with two limiting protrusions, corresponding to the open and closed states of the adapter; the inner wall of the adapter is provided with a limiting flange that is movably fitted between the two limiting protrusions.

[0009] Preferably, the peripheral surface of the main body is provided with an ON / OFF indicator, and the peripheral surface of the adapter is provided with an indicator arrow that points to the indicator as the adapter rotates.

[0010] Preferably, the material passage tube is recessed to form a material passage annular groove, and the opposite surface of the discharge cover protrudes in the direction of the discharge hole to form a guide flange; the guide flange is embedded in the material passage annular groove and does not contact the inner or outer walls of the material passage annular groove.

[0011] Preferably, the opposite surface of the discharge cover protrudes outward in the direction of the discharge hole to form a first sealing flange; the end face of the adapter is provided with a boss, the material passage pipe and the surrounding material passage groove are coaxially provided on the end face of the boss, and the periphery of the boss protrudes to form a second sealing flange; the first sealing flange is tightly fitted on the periphery of the boss, and the second sealing flange abuts against the opposite surface of the discharge cover.

[0012] The discharge cover is snapped together with the adapter.

[0013] Preferably, the discharge cover has a ring of hooks around its periphery, and the adapter has a groove on its periphery for the hooks to engage.

[0014] The decorative discharge packaging hose also includes a cover that is threadedly fitted to the end of the main body, and a sealing gasket disposed in the cover; when the cover is in the closed state, the sealing gasket blocks the discharge end of each discharge hole.

[0015] Preferably, the circumferential surface of the main body has a plurality of first anti-rotation protrusions arranged in parallel, and the inner wall of the cover has a plurality of second anti-rotation protrusions arranged in parallel for the first anti-rotation protrusions to move and cooperate with; the sealing gasket is made of silicone material; and the cover body has an installation groove for the sealing gasket to be embedded.

[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0031] refer to Figure 1-4As shown, this utility model discloses a patterned discharge packaging hose, including a body 1, an adapter 2, and a discharge cap 3;

[0032] The end face of the main body 1 is provided with a discharge hole 11;

[0033] The adapter 2 is rotatably sleeved on the end of the body 1, and its end face is provided with a material passage hole 21 opposite to the material outlet hole 11. The material passage hole 21 may or may not be connected to the material outlet hole 11 as the adapter 2 rotates.

[0034] The discharge cover 3 is fitted onto the end face of the adapter 2 and is provided with discharge holes 31 that are distributed at equal angles around the axis of the material passage hole 21;

[0035] A discharge channel is formed between the end face of the body 1 and the opposite face of the discharge cover 3, which connects the material passage hole 21 and the discharge hole 31. The discharge channel forms at least one bend between the material passage hole 21 and the discharge hole 31.

[0036] Through the above solution, this utility model provides a connector 2 between the discharge cap 3 with the discharge hole 31 and the main body 1. The connector 2 has a material passage hole 21 that can be connected to or disconnected from the discharge hole 11 as it rotates, allowing the user to open and close the discharge hole 11 by rotating the connector 2. This ensures that the discharge from the packaging tube is controllable and prevents leakage due to shaking or squeezing when not in use. At the same time, a discharge channel with at least one bend is provided between the material passage hole 21 and the discharge hole 31 of the connector 2, so that the material passage hole 21 and the discharge hole 31 are connected. The flow distance between 31 is extended, so even if some material is pushed by air pressure at the moment of extrusion, it will not jump out of the discharge hole 31, but will remain in the discharge channel and be pushed forward by the subsequently extruded material. Combined with the evenly distributed discharge holes 31, the final effect is that each discharge hole 31 discharges material evenly and at the same time, which can simulate the state of petals blooming. The discharge cover 3 and the body 1 are separate designs, which allows the discharge cover 3 to be replaced to match different discharge hole 31 shapes. It is also convenient to process the body 1 and the discharge cover 3 separately to obtain the discharge channel shape that meets the usage requirements.

[0037] The following shows specific embodiments of this utility model.

[0038] In this embodiment, the discharge hole 31 is petal-shaped with a bend between its two ends. One end of the petal is smaller and faces the axis of the feed hole 21, while the other end of the petal is larger and faces away from the axis of the feed hole 21.

[0039] The end face of the main body 1 is provided with a sealing post 12, and the discharge hole 11 is provided around the sealing post 12 and there is at least one such hole. The axis of the adapter 2 is provided with a feed pipe 22, and the feed hole 21 is provided at the axis of the feed pipe 22. The adapter 2 is threadedly connected to the main body 1. The sealing post 12 moves axially as the adapter 2 rotates and is driven by the thread, thereby sealing or opening the inner end of the feed pipe 22, so as to realize the controllable opening and closing of the discharge hole 11.

[0040] In some embodiments of this utility model, the peripheral surface of the main body 1 is provided with two limiting protrusions 13, corresponding to the open and closed states of the adapter 2; the inner wall of the adapter 2 is provided with a limiting flange 23 that is movably engaged between the two limiting protrusions 13. This limits the opening and closing angle of the adapter 2, making the user's operation easier, allowing for a quick rotation to the open / closed state without over-rotation.

[0041] Furthermore, the peripheral surface of the main body 1 is provided with an ON / OFF indicator 14, and the peripheral surface of the adapter 2 is provided with an indicator arrow 24 that points to the indicator 14 as the adapter 2 rotates. Thus, the current open / closed state of the product can be clearly indicated.

[0042] In some embodiments of this utility model, a material passage groove 25 is formed around the material passage tube 22, and a guide flange 32 is formed on the opposite side of the discharge cover 3 protruding in the direction inside the discharge hole 31. The guide flange 32 is embedded in the material passage groove 25 and does not contact the inner or outer walls of the material passage groove 25, i.e., a certain gap is reserved, thereby forming the above-mentioned discharge channel. (Refer to...) Figure 1 The discharge channel, formed by the material passage groove 25 and the guide flange 32, allows the material to undergo multiple turns—horizontal, downward, upward, horizontal, and upward—after being extruded through the material passage hole 21. This greatly increases the discharge distance and ensures the product's discharge effect.

[0043] Furthermore, the opposite surface of the discharge cover 3 protrudes outward from the discharge hole 31 to form a first sealing flange 33; the end face of the adapter 2 is provided with a boss 26, the aforementioned material passage pipe 22 and its surrounding material passage groove 25 are coaxially arranged on the end face of the boss 26, and a second sealing flange 27 protrudes outward from the periphery of the boss 26; the first sealing flange 33 is tightly fitted on the periphery of the boss 26, and the second sealing flange 27 abuts against the opposite surface of the discharge cover 3 to achieve a seal after the discharge cover 3 is closed on the end face of the adapter 2, preventing material leakage, and the second sealing flange 27 can prevent the opposite surface of the discharge cover 3 from fitting against the boss 26, so as to form the aforementioned discharge channel.

[0044] The aforementioned discharge cover 3 is snapped together with the adapter 2 for easy disassembly and assembly.

[0045] Furthermore, the circumference of the discharge cover 3 is provided with a ring of hooks 34, and the circumference of the adapter 2 is provided with a groove 28 for the hooks 34 to engage.

[0046] This utility model also includes a cover 4 that is threadedly connected to the end of the main body 1, and a sealing gasket 5 disposed inside the cover 4; when the cover 4 is in the closed state, the sealing gasket 5 blocks the discharge ends of each discharge hole 31. The cover 4 can cover the discharge cover 3 to prevent dust from contaminating the discharge cover 3, while the sealing gasket 5 can block the discharge holes 31 to prevent material leakage during non-use and avoid contaminating the cover 4.

[0047] Furthermore, the circumferential surface of the main body 1 is provided with several parallel first anti-rotation protrusions 15, and the inner wall of the cover 4 is provided with several parallel second anti-rotation protrusions 41 for the first anti-rotation protrusions 15 to move and cooperate with. As a result, the rotation of the cover 4 has a clear sense of the stops, which can provide feedback to the user's operating feel and prevent over-rotation.

[0048] In addition, the sealing gasket 4 can be made of silicone material; the cover body 4 is provided with an installation groove 42 for the sealing gasket 4 to be embedded.

[0049] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
