Description

Technical Field

[0001] This utility model relates to the field of press pump technology, specifically to a deformable long spout cap. Background Technology

[0002] In the field of liquid packaging for daily chemical products and pharmaceutical preparations, push pumps are widely used in long-nozzle cap structures because they can dispense liquid in a quantitative manner and are easy to operate.

[0003] However, existing long spout caps have significant shortcomings in practical use:

[0004] On the one hand, the press cap is prone to accidental discharge of liquid due to accidental activation, resulting in waste or even pollution, especially in transportation and carrying scenarios where the risk of accidental activation is higher;

[0005] On the other hand, the liquid outlet of the press cap lacks a reliable sealing and protection structure. Long-term exposure makes it susceptible to contamination by dust and impurities, affecting the quality of the liquid. Furthermore, the traditional protective cover and the press pump have poor locking and unlocking linkage, making operation cumbersome and difficult to balance preventing accidental touches and ease of use. Utility Model Content

[0006] The purpose of this invention is to provide a deformable long spout cap in order to solve the above problems, as detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a deformable long spout cap, comprising:

[0009] A push-button pump with a push-button cap;

[0010] A limiting sleeve, slidably connected to the press pump, is used to lock the press cap of the press pump to prevent the press cap from being accidentally touched.

[0011] The protective cover is rotatably connected to the limiting sleeve and is used to seal the liquid outlet of the press cap;

[0012] While the limiting sleeve locks the pressing cap, the protective cover can close the pressing cap. The limiting sleeve can release the locking of the pressing cap by moving away from the pressing cap, and at the same time, the protective cover flips down and disengages from the pressing cap.

[0013] When the aforementioned deformable long nozzle cap is used, the protective cover can cover the pressing cap when the limiting sleeve locks the pressing pump. At this time, the bottom of the pressing cap is fitted with the inner wall of the protective cover. The protective cover and the limiting sleeve can limit and seal the pressing cap, preventing it from pressing down to squeeze material and from contacting air. The limiting component can lock the position of the limiting sleeve. The limiting component can be released to adjust the position of the limiting sleeve on the pressing pump.

[0014] By moving the limiting sleeve downwards, the protective cover moves away from the bottom surface of the long nozzle of the press cap. At that time, the protective cover swings downwards under the action of gravity, the liquid outlet of the press cap unfolds, and the press cap can be used.

[0015] Preferably, the limiting sleeve is provided with a limiting component, and the pressing pump is provided with an annular limiting surface. The limiting component and the annular limiting surface cooperate to adjust the position of the limiting sleeve on the pressing pump.

[0016] Preferably, the limiting component includes a fixed ring and a limiting ring inserted into the fixed ring. The bottom of the limiting ring corresponds to the annular limiting surface. The limiting ring has a deformation capability. By squeezing, the limiting ring tends to elliptical deformation, which can cause the limiting ring to be misaligned with the annular limiting surface.

[0017] Preferably, the limiting ring includes a fixing plate and a pressing surface. Two elastic pieces with deformation function are fixedly connected between the fixing plate and the pressing surface. The elastic pieces correspond to the annular limiting surface. Fixing grooves are opened at corresponding positions on the inner wall of the fixing plate and the limiting sleeve. The two sides of the fixing plate are respectively inserted into the two fixing grooves.

[0018] Preferably, the fixing ring is slidably connected to the surface of the pump, and a baffle corresponding to the pressing surface is fixedly connected to the fixing ring. In the initial state, there is a gap between the pressing surface and the baffle.

[0019] Preferably, the inner walls of the limiting ring and the limiting sleeve are respectively provided with a guide groove and a sliding groove, and the surface of the pressing pump is fixedly connected with a guide block that fits with the guide groove and the sliding groove.

[0020] Preferably, the inner wall of the limiting sleeve is provided with a groove, the fixing ring is fixedly connected with a protrusion for engaging the groove, and the side of the limiting sleeve is provided with an opening that matches the pressing surface.

[0021] Preferably, the press cap has a long nozzle design, and the liquid outlet of the press cap has a bevel design that fits with the gap of the inner wall of the protective cover.

[0022] Preferably, the limiting sleeve has a notch on its side, and the protective cover is rotatably connected to the notch by a pin. A rocker arm is fixedly connected to the protective cover, and the rocker arm and the protective cover are distributed on both sides of the pin. The rocker arm corresponds to the bottom surface of the long nozzle of the pressing cap.

[0023] Preferably, the notch of the limiting sleeve has an inclined surface for supporting the protective cover, which supports the protective cover and prevents the pry plate from being perpendicular to the bottom of the pressing cap after the protective cover is unfolded.

[0024] The beneficial effects are:

[0025] 1. By using the axial constraint of the limiting sleeve on the pressing cap, the contact locking between the limiting component spring and the annular limiting surface of the pressing pump, and the spacing protection between the fixed ring baffle and the pressing surface of the limiting ring, double anti-accidental contact is achieved, eliminating liquid waste and pollution caused by unexpected liquid discharge during transportation and carrying.

[0026] 2. The unlocking mechanism is achieved through the linkage between the pressing deformation of the limiting ring and the downward movement of the limiting sleeve, combined with the design of the protective cover flipping under gravity, thus realizing an integrated unlocking and opening operation and improving ease of use;

[0027] 3. By sliding the pump guide block with the guide groove of the limiting ring and the sliding groove of the limiting sleeve, engaging the fixed ring protrusion with the groove of the limiting sleeve, and supporting the inclined surface of the limiting sleeve with the protective cover, the components are stably positioned, and the durability of the device is improved.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] See Figures 1-7 As shown, this utility model provides a deformable elongated spout cap, comprising:

[0040] The press pump 1 has a press cap 5;

[0041] Limit sleeve 2 is slidably connected to the press pump 1 and is used to lock the press cap 5 of the press pump 1 to prevent the press cap 5 from being accidentally touched.

[0042] Protective cover 4 is rotatably connected to limit sleeve 2 and is used to seal the liquid outlet of press cap 5;

[0043] While the limiting sleeve 2 locks the pressing cap 5, the protective cover 4 can close the pressing cap 5. The limiting sleeve 2 can release the locking of the pressing cap 5 by moving away from the pressing cap 5, and at the same time the protective cover 4 flips down and disengages from the pressing cap 5.

[0044] As an optional implementation, a limiting component 3 is provided inside the limiting sleeve 2, and an annular limiting surface 13 is provided on the pressing pump 1. The limiting component 3 and the annular limiting surface 13 cooperate to adjust the position of the limiting sleeve 2 on the pressing pump 1.

[0045] The limiting component 3 includes a fixed ring 10 and a limiting ring 9 inserted into the fixed ring 10. The bottom of the limiting ring 9 corresponds to the annular limiting surface 13. The limiting ring 9 has the ability to deform. By squeezing, the limiting ring 9 tends to deform into an ellipse, which can make the limiting ring 9 misalign with the annular limiting surface 13.

[0046] The limiting sleeve 2 is fitted onto the outside of the press pump 1 and is locked by the internal limiting component 3. In the limiting component 3, the spring piece 15 of the limiting ring 9 is tightly fitted with the annular limiting surface 13 of the press pump 1 to form an axial limit; at the same time, the fixing plate 16 of the limiting ring 9 is inserted into the fixing groove 18 on the inner wall of the limiting sleeve 2 on both sides to ensure that the limiting ring 9 and the limiting sleeve 2 are relatively fixed.

[0047] The limiting ring 9 includes a fixing plate 16 and a pressing surface 17. Two deformable spring pieces 15 are fixedly connected between the fixing plate 16 and the pressing surface 17. The spring pieces 15 correspond to the annular limiting surface 13. Fixing grooves 18 are provided at corresponding positions on the inner wall of the fixing plate 16 and the limiting sleeve 2. The two sides of the fixing plate 16 are respectively inserted into the two fixing grooves 18.

[0048] The limiting ring 9 is composed of "fixed plate 16 + pressing surface 17 + two spring pieces 15":

[0049] The two sides of the fixing plate 16 are inserted into the fixing grooves 18 on the inner wall of the limiting sleeve 2 to ensure that the limiting ring 9 is relatively fixed to the limiting sleeve 2 and moves synchronously with the limiting sleeve.

[0050] The spring piece 15 has elastic deformation capability. In the initial state, it fits tightly with the annular limiting surface 13 of the press pump 1, locking the limiting sleeve 2 so that it cannot move.

[0051] The pressing surface 17 is exposed at the "opening" on the side of the limiting sleeve 2, allowing the user to squeeze the pressing surface 17. When the pressing surface 17 is squeezed, the limiting ring 9 tends to deform into an elliptical shape due to the force, and the spring piece 15 disengages from the annular limiting surface 13, thus releasing the lock of the limiting sleeve 2.

[0052] The retaining ring 10 is slidably connected to the surface of the pump 1, and a baffle 14 corresponding to the pressing surface 17 is fixedly connected to the retaining ring 10. In the initial state, there is a gap between the pressing surface 17 and the baffle 14 of the limiting ring 9. The retaining ring 10 is slidably connected to the surface of the pump 1, and the baffle 14 is fixed on it, with an initial gap between the baffle 14 and the pressing surface 17 of the limiting ring 9.

[0053] The baffle 14 serves to "prevent accidental contact" by preventing the pressing surface 17 from deforming due to accidental force when the user does not actively press it.

[0054] In addition, the pressing surface 17 does not protrude from the surface of the limiting sleeve 2 in its initial state.

[0055] The inner walls of the limiting ring 9 and the limiting sleeve 2 are respectively provided with guide groove 7 and slide groove 12, and the surface of the press pump 1 is fixedly connected with guide block 11 that is in clearance fit with guide groove 7 and slide groove 12.

[0056] The inner wall of the limiting sleeve 2 is provided with a groove 19, and a protrusion 20 for engaging the groove 19 is fixedly connected to the fixing ring 10. The side of the limiting sleeve 2 is provided with an opening that matches the pressing surface 17. The protrusion 20 on the fixing ring 10 engages with the groove 19 on the inner wall of the limiting sleeve 2 to ensure that the relative position of the fixing ring 10 and the limiting sleeve 2 is stable, and the baffle 14 is always aligned with the pressing surface 17.

[0057] The press cap 5 features a long nozzle design, and its outlet has a beveled design that fits with the inner wall of the protective cap 4. The protective cap 4 is rotatably connected to the notch of the limiting sleeve 2 via a pin, and its inner wall fits with the beveled outlet of the press cap 5 to completely seal the outlet.

[0058] The limiting sleeve 2 has a notch on its side. The protective cover 4 is rotatably connected to the notch through a pin. A rocker plate 6 is fixedly connected to the protective cover 4. The rocker plate 6 and the protective cover 4 are distributed on both sides of the pin. The rocker plate 6 corresponds to the bottom surface of the long nozzle of the pressing cap 5. When the limiting sleeve 2 slides down, the rocker plate 6 moves down synchronously with the limiting sleeve and disengages from the bottom surface of the long nozzle of the pressing cap 5.

[0059] After losing support, the protective cover 4 flips downward around the pin axis under its own gravity, and the liquid outlet is fully opened.

[0060] Below the notch of the limiting sleeve 2, there is an inclined surface 8 for supporting the protective cover 4. This is to support the protective cover 4 and prevent the rocker plate 6 from being perpendicular to the bottom of the pressing cap 5 after the protective cover 4 is unfolded. After the protective cover 4 is flipped, it will rest on the inclined surface, which will prevent the protective cover 4 from being over-flipped, causing the rocker plate 6 to be perpendicular to the bottom of the pressing cap 5 and making subsequent reset difficult. At the same time, it ensures that the protective cover is stable and does not wobble after it is opened.

[0061] The device has strong linkage: it can simultaneously complete the "limit release + protective cover opening" with only one continuous action of "squeezing + moving down", making it easy to operate;

[0062] Dual protection: When locked, the limiting sleeve prevents accidental pressing, and the protective cover seals the outlet to prevent contamination, solving two major pain points of traditional push pumps;

[0063] Stable structure: The guide block and guide groove / slide groove are matched to prevent misalignment, the spring plate of the limit component is positioned to prevent loosening, and the inclined support prevents the protective cover from shaking, ensuring long-term reliability.

[0064] With the above structure, when the limiting sleeve 2 locks the press pump 1, the protective cover 4 can cover the press cap 5. At this time, the bottom of the press cap 5 is in clearance fit with the inner wall of the protective cover 4. The protective cover 4 and the limiting sleeve 2 can limit and seal the press cap 5, so that it cannot be pressed down to squeeze material and cannot come into contact with air. The position of the limiting sleeve 2 can be locked by the limiting component 3. The position of the limiting sleeve 2 on the press pump 1 can only be adjusted by releasing the limiting component 3.

[0065] By moving the limiting sleeve 2 downwards, the protective cover 4 moves away from the bottom surface of the long nozzle of the pressing cap 5, and the protective cover 4 swings downwards under the action of gravity, the liquid outlet of the pressing cap 5 unfolds, and the pressing cap 5 can be used.

[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
