Description

Technical Field

[0001] This utility model relates to the field of sealant bottles, specifically to a trigger-extrusion type sealant packaging bottle. Background Technology

[0002] Currently, sealant products, such as silicone sealants, are widely used in: 1. In the construction industry, for sealing curtain walls and windows, especially for sealing joints in glass curtain walls and aluminum composite panel curtain walls, ensuring long-term weather resistance and waterproofing, filling gaps between aluminum alloy doors and windows and walls to prevent wind and rain penetration; 2. In the automotive and industrial manufacturing industry, for sealing automotive parts, used to bond automotive interior materials (metal, fabric, plastic), sealing high-temperature parts such as hoods and exhaust pipes to replace traditional rubber gaskets, and for leak-proof sealing of equipment such as flat flanges and water pumps; 3. In daily home life, used to seal toilet bases and sink edges to prevent water seepage and mold growth, fill gaps between countertops and walls to improve aesthetics and durability, or for bonding fish tanks and glass crafts to ensure long-term waterproofing.

[0003] However, commercially available silicone sealant products generally require storage in bottles. These bottles have a neck with an outward-protruding nozzle, which is integrally formed with a sealing strip. To use, the sealing strip is first cut off, and then the nozzle is screwed onto the neck. The bottle contains a tail plug, and the silicone sealant is stored between the tail plug and the neck. The tail end of the bottle is open. The bottle is inserted into a caulking gun, and the caulking gun's push rod extends into the rear of the bottle. The push rod pushes the tail plug towards the neck, thus expelling the silicone sealant through the nozzle. However, when people buy or use traditional silicone sealant, they need to buy and carry a caulking gun separately. It is very inconvenient to use silicone sealant without a caulking gun. If the user does not have a caulking gun, they need to use a screwdriver or stick to push the end cap, which is laborious and inconvenient. Therefore, it is necessary to improve the sealant bottle (especially silicone sealant). Summary of the Invention

Detailed Implementation

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] This utility model relates to a trigger-extrusion type sealing adhesive packaging bottle, such as... Figures 1 to 4 As shown, the device includes a bottle body 1, with a bottle mouth 101 formed at the upper end and a bottle bottom 102 formed at the lower end. A piston 2 is provided inside the bottle body 1, and a glue storage chamber 1001 and a gas storage chamber 1002 are formed inside the bottle body 1. The glue storage chamber 1001 is located between the piston 2 and the bottle mouth 101, and the gas storage chamber 1002 is located between the piston 2 and the bottle bottom 102. In other words, the piston 2 separates the glue storage chamber 1001 and the gas storage chamber 1002. A glue dispensing valve is provided at the bottle mouth 101. The dispensing valve is used to control the opening and closing of the bottle opening 101. Therefore, the dispensing valve can be a ball valve, butterfly valve or angle valve of the prior art. For example, you can refer to the "A ball valve that is easy to replace the packing" in Chinese Utility Model Patent Publication No. CN210661462U, the "wear-resistant and corrosion-resistant butterfly valve" in Chinese Utility Model Patent Publication No. CN205859175U, or the "angle valve" in Chinese Utility Model Patent Publication No. CN206830907U.

[0033] The working principle of this utility model is briefly explained below: Figure 1As shown, the silicone sealant is stored in the storage cavity 1001, and the silicone sealant is commonly known as glass glue in the market. The compressed gas (which can be nitrogen or air) is injected into the storage cavity 1002, so that the compressed gas in the storage cavity 1002 exerts an upward pushing force on the piston 2, and the silicone sealant in the storage cavity 1001 is squeezed by the piston 2, that is, the silicone sealant in the storage cavity 1001 fills the storage cavity 1001. Since the silicone sealant in the storage cavity 1001 blocks the flow of compressed gas to the bottle opening 101, even if there is a slight air leakage between the piston 2 and the inner wall of the bottle body 1, the gas is not easy to leak in large quantities to the storage cavity 1001. When the silicone sealant is needed, the glue outlet valve is opened, so that the piston 2 moves upward under the pressure of the compressed gas, and the silicone sealant is pushed by the piston 2 to pass through the glue outlet valve and be discharged. As the silicone sealant is discharged, the piston 2 moves upward, and the storage cavity 1001 gradually shrinks. After the silicone sealant is used up, the glue outlet valve is closed, and the silicone sealant stops discharging. Therefore, the silicone sealant bottle of the utility model eliminates the use of a glue gun and the trouble of purchasing and carrying the glue gun, and is beneficial to users to use the silicone sealant at any time and anywhere. Moreover, since the piston 2 is driven by compressed gas, it is beneficial to save labor and simplify use. Therefore, the silicone sealant bottle of the utility model is easy to use, and users can focus more on applying the silicone sealant to the desired position.

[0034] Further, as shown in Figure 2 and Figure 4 , the glue outlet valve comprises a bottle opening sealing sleeve 3 and a valve rod 4. The bottle opening sealing sleeve 3 is arranged in the bottle opening 101. Specifically, the bottle opening 101 is formed with a bottle opening flange portion 1011, and a bottle opening support ring 11 is arranged at the bottle opening 101. As shown in Figure 6 , the bottle opening support ring 11 can be made of stainless steel. The inner circle of the bottle opening support ring 11 is formed with a connecting hole 1101, and the outer circle of the bottle opening support ring 11 is formed with a buckling portion 1102. The buckling portion 1102 is annular, as shown in Figure 2 , the buckling portion 1102 clamps the bottle opening flange portion 1011, thereby relatively fixing the bottle opening support ring 11 and the bottle opening 101, and sealingly connecting the buckling portion 1102 and the bottle opening flange portion 1011. The bottle opening sealing sleeve 3 can be made of rubber. Specifically, the bottle opening sealing sleeve 3 passes through the connecting hole 1101, as shown in Figure 7 , the outer part of the bottle opening sealing sleeve 3 is formed with a sealing clamping groove 302, which is annular, as shown in Figure 2 , the edge of the connecting hole 1101 is arranged in the sealing clamping groove 302, thereby sealingly connecting the bottle opening sealing sleeve 3 and the bottle opening support ring 11. When installing the bottle opening sealing sleeve 3, the bottle opening sealing sleeve 3 needs to be squeezed into the connecting hole 1101 (during which the bottle opening sealing sleeve 3 is elastically deformed), as shown in Figure 7As shown, a sliding hole 301 is formed in the bottle mouth sealing sleeve 3, and the sliding hole 301 is located at the central axis of the bottle mouth sealing sleeve 3. Figure 8 As shown, the valve rod 4 comprises a rod body 40 and a valve piece 41. A glue passing hole 401 is formed in the rod body 40, and the glue passing hole 401 is located at the central axis of the rod body 40. The valve piece 41 is arranged on the lower end of the rod body 40, that is, the valve piece 41 axially seals the lower end of the glue passing hole 401. The valve piece 41 is integrally arranged with the rod body 40. The lower end of the rod body 40 is formed with a glue inlet groove 402, which is a wall body extending through the rod body 40 in the radial direction. Thus, the glue inlet groove 402 is connected to the lower end of the glue passing hole 401. The glue inlet groove 402 is uniformly distributed in the circumferential direction. Figure 2 As shown, the rod body 40 is slidingly arranged in the sliding hole 301, that is, the rod body 40 can axially move (up and down) in the sliding hole 301. The valve piece 41 is arranged on the lower end of the bottle mouth sealing sleeve 3. As described above, the piston 2 is pushed upward by the compressed gas in the gas storage cavity 1002 to press the silicone sealant in the glue storage cavity 1001. Thus, the silicone sealant is pressed to make the valve piece 41 press the lower end of the bottle mouth sealing sleeve 3. Thus, the upper surface of the valve piece 41 is tightly sealed with the lower end surface of the bottle mouth sealing sleeve 3. When the user moves the valve rod 4 downward to overcome the pressure of the silicone sealant, the upper surface of the valve piece 41 is separated from the lower end of the bottle mouth sealing sleeve 3. Thus, the glue inlet groove 402 is exposed to the silicone sealant. Under the pushing of the piston 2, the silicone sealant is pushed into the glue inlet groove 402, and then the silicone sealant enters the glue passing hole 401 and flows upward along the glue passing hole 401 and is discharged out of the rod body 40, which is equivalent to opening the bottle mouth 101. When the user moves the valve rod 4 upward, the valve piece 41 is pushed by the pressure of the silicone sealant to return to the state of pressing the lower end of the bottle mouth sealing sleeve 3, thereby closing the bottle mouth 101. The glue outlet valve of the present embodiment realizes good sealing by the pressure of the silicone sealant. The structure of the glue outlet valve is relatively simple, and the operation of opening and closing the bottle mouth 101 is relatively simple.

[0035] Further, as shown in Figure 7 As shown, the upper end of the bottle mouth sealing sleeve 3 is formed with an elastic supporting sleeve part 31, and the elastic supporting sleeve part 31 is located on the upper side of the bottle mouth 101. Figure 2 As shown, the rod body 40 coaxially passes through the elastic supporting sleeve part 31. Figure 8 As shown, the rod body 40 is formed with a convex ring part 42. Figure 2As shown, the convex ring part 42 is attached to the upper side of the upper end of the elastic supporting sleeve part 31, so when the user moves the valve rod 4 downward to open the glue inlet groove 402, the convex ring part 42 presses the elastic supporting sleeve part 31 downward, and the elastic supporting sleeve part 31 is elastically compressed and deformed, specifically, the elastic supporting sleeve part 31 is elastically expanded and deformed; in the free state, the inner wall of the elastic supporting sleeve part 31 can be a concave arc line, that is, the inner diameter of the elastic supporting sleeve part 31 is small at both ends and large in the middle (in the up-down direction), so when the convex ring part 42 presses the upper end of the elastic supporting sleeve part 31, it is beneficial to the elastic supporting sleeve part 31 to easily expand elastically; when the user releases the valve rod 4, the elastic restoring force of the elastic supporting sleeve part 31 pushes the convex ring part 42 upward, so that the valve piece 41 is reset upward and presses against the lower end of the bottle mouth sealing sleeve 3, which further enables the valve piece 41 to be stably and effectively reset.

[0036] Further, as shown in Figure 1 and Figure 4 , the glue outlet valve includes a valve cover 5 and a valve handle 7, as shown in Figure 2 , the valve cover 5 is arranged on the upper side of the bottle body 1, as shown in Figure 12 , the valve handle 7 is formed with a seesaw part 71, the seesaw part 71 is formed with a convex push piece 712 for pressing the convex ring part 42, one end of the seesaw part 71 is formed with a prying end 713, as shown in Figure 2 and Figure 5 , the prying end 713 is connected to the valve cover 5, in other words, the structure of the seesaw part 71 is similar to that of a seesaw, the convex push piece 712 serves as a pivot point, when the other end of the seesaw part 71 is pressed downward, due to the connection of the prying end 713 to the valve cover 5, that is, the prying end 713 prys the valve cover 5 upward, but the valve cover 5 blocks the upward movement of the prying end 713, relatively, the convex push piece 712 moves downward, and the seesaw part 71 swings clockwise (in the visual direction of Figure 2 ), so the convex push piece 712 pushes the convex ring part 42 downward, thereby opening the glue inlet groove 402, that is, pressing the valve handle 7 is the trigger action of the glue outlet valve to make the silicone sealant be squeezed out. By arranging the valve handle 7, it is not necessary to hold the rod body 40 with the hand to move it downward, so the hand slipping situation can be avoided, which is beneficial to the convenient opening of the bottle mouth 101, and when the distance from the contact point of the hand to the convex push piece 712 to the distance from the prying end 713 to the convex push piece 712 is greater, the seesaw part 71 can act as a lever, which is beneficial to save effort. When the valve handle 7 is released, the elastic restoring force of the elastic supporting sleeve part 31 pushes the convex ring part 42 upward, and the convex ring part 42 drives the valve handle 7 to swing counterclockwise to reset.

[0037] Further, as shown in Figure 9 , the upper part of the valve cover 5 is formed with a spiral groove 521, that is, the spiral groove 521 is arranged along a spiral line, so that one end of the spiral groove 521 is lower in position, and the other end of the spiral groove 521 is higher in position, the spiral groove 521 is formed with a groove upper edge part 5211 for attaching to the prying end 713, as shown inFigure 2 and Figure 5 As shown, the pry end 713 is located within the spiral groove 521. Therefore, when the other end of the aforementioned rocker arm 71 is pressed down by hand, the pry end 713 abuts against the upper edge of the groove 5211, which prevents the pry end 713 from moving upwards. Correspondingly, the convex pusher 712 moves downwards. Rotating the valve handle 7 around the axis of the valve stem 4 causes the pry end 713 to slide within the spiral groove 521, thus changing the height of the portion of the spiral groove 521 that contacts the pry end 713 relative to the convex ring 42. When the pry end 713 is positioned to contact the lower end of the spiral groove 521, the aforementioned rocker arm... The other end of the rocker arm 71 is positioned higher, resulting in a greater distance between the other end of the rocker arm 71 and the valve cover 5. When the rocker arm 71 is swung clockwise around the convex push plate 712, the other end of the rocker arm 71 can move downwards to a greater extent, which in turn causes the convex push plate 712 to move downwards to a greater extent, thus opening the glue inlet groove 402 to a greater extent. Conversely, when the pry end 713 is positioned to contact the upper end of the spiral groove 521, the other end of the rocker arm 71 can move downwards to a smaller extent, resulting in a smaller downward movement of the valve plate 41 and a smaller opening of the glue inlet groove 402. By providing the spiral groove 521, the glue flow rate can be adjusted.

[0038] Furthermore, such as Figure 12 As shown, a hook groove 7131 is formed on the upper side of the pry end 713, and the hook groove 7131 is also provided along a spiral line, such as... Figure 2 and Figure 5 As shown, the upper edge 5211 of the groove is located within the hook groove 7131, thus the upper edge 5211 of the groove guides the horizontal (approximate) rotation of the valve handle 7. Specifically, the cross-sectional shape of the hook groove 7131 is "V" shaped, that is to say, the hook groove 7131 is a "V" shaped groove structure, and as... Figure 2 and Figure 9 As shown, the upper edge 5211 of the groove is wider at the top and narrower at the bottom, as... Figure 2 As shown, the upper edge portion 5211 of the groove is made into a pointed tip, which facilitates the fitting of the upper edge portion 5211 of the groove to the hook groove 7131.

[0039] Furthermore, such as Figure 2 and Figure 4 As shown, the glue dispensing valve includes a glue dispensing pipe 6, which is sleeved outside the rod body 40, as... Figure 11 As shown, an inverted stepped portion 601 is formed inside the dispensing tube 6, such as... Figure 2 As shown, the stepped portion 601 abuts against the upper side of the protruding ring portion 42, as... Figure 11 As shown, a support step 602 is formed on the outside of the dispensing tube 6, such as... Figure 12 As shown, the rocker arm 71 has a through groove 711, such as Figure 5As shown, the glue outlet pipe 6 passes through the through slot 711, and the pushing piece 712 abuts against the upper side of the support step 602. In other words, the pushing piece 712 indirectly pushes the convex ring part 42 through the inverted step part 601. By additionally providing the glue outlet pipe 6, the upper end of the glue outlet pipe 6 is the glue outlet part. The upper end of the glue outlet pipe 6 can be screw-connected with the glue nozzle 9. Thus, the silicone sealant discharged through the upper end of the rod body 40 enters the glue nozzle 9 through the upper end of the glue outlet pipe 6, and then the silicone sealant is discharged from the upper end of the glue nozzle 9. When the specification of the glue nozzle 9 changes, the structure of the valve rod 4 can remain unchanged, but the upper end structure of the glue outlet pipe 6 can be changed accordingly, so as to facilitate flexible production.

[0040] Further, as shown in Figure 12 , the valve handle 7 is formed with a pressing arm part 72, the upper end of the pressing arm part 72 is integrally connected with the other end of the aforementioned seesaw part 71, the pressing arm part 72 is downwardly bent relative to the seesaw part 71, for example, the pressing arm part 72 is perpendicular to the seesaw part 71, as shown in Figure 1 , when a user applies a pushing force along the radial direction of the bottle body 1 to the pressing arm part 72, the valve handle 7 rotates clockwise, and the pushing piece 712 presses the valve rod 4. When the lower end of the pressing arm part 72 rotates to contact the outer wall of the bottle body 1, the bottle body 1 limits the valve handle 7, so that the valve handle 7 cannot continue to rotate clockwise. Thus, the opening range of the glue inlet groove 402 is limited. When the valve handle 7 is rotated to a position around the central axis of the bottle body 1, the distance between the lower end of the pressing arm part 72 and the outer wall of the bottle body 1 changes. Since the pressing arm part 72 is downwardly bent relative to the seesaw part 71, a user can press the pressing arm part 72 with the thumb of one hand, and hold the bottle body 1 with the remaining four fingers of the same hand. Thus, one-handed control of the glue outlet valve can be achieved, which is convenient for operation and allows the other hand to perform other operations at the same time. Since the pressing arm part 72 is relatively close to the bottle mouth 101 and the glue nozzle 9 (rather than being arranged at a position corresponding to the bottle bottom 102), the position of the glue outlet of the glue nozzle 9 is easy to control, thereby facilitating accurate application of silicone sealant.

[0041] Further, as shown in Figure 9 , the upper part of the valve cover 5 is formed with a convex wall part 52. In a top view, the convex wall part 52 is in the shape of a circular arc. A screw groove 521 is formed on the convex wall part 52, as shown in Figure 2 , the convex wall part 52 is covered with an outer cover 8, as shown in Figure 3 and Figure 13 , one side of the outer cover 8 is formed with a window 801, the seesaw part 71 passes through the window 801, and the pressing arm part 72 is located outside the outer cover 8, as shown in Figure 2 , the upper end of the glue outlet pipe 6 passes through the outer cover 8. Thus, the outer cover 8 covers the pry end 713 and the screw groove 521, so that the outer cover 8 plays a decorative role, which is conducive to making the sealant bottle have a relatively simple appearance, and also avoids foreign matter from being stuck between the pry end 713 and the screw groove 521, which is conducive to stable operation of the glue outlet valve.Figure 9 and Figure 10 As shown in the figure, the lower part of the valve cover 5 is formed with a cover body 51, and a avoiding hole 502 is formed at the center axis of the cover body 51, as shown in the figure. Figure 2 The elastic support sleeve part 31 is arranged in the avoiding hole 502, and the upper end of the cover body 51 is connected with the lower end of the convex wall part 52 integrally, as shown in the figure. Figure 10 The bottom of the cover body 51 is formed with a ring buckle groove 501, which is axially (upward) concave, and an inner flange 5011 is formed at the opening of the lower end of the ring buckle groove 501, as shown in the figure. Figure 2 The ring buckle part 1102 is arranged in the ring buckle groove 501, and the inner flange 5011 buckles the radial outer end of the ring buckle part 1102, so as to avoid the axial (upward) separation of the valve cover 5 from the bottle body 1, and the ring buckle groove 501 is positioned radially opposite to the bottle body 1. The connection structure of the above-mentioned valve cover 5 and the bottle mouth supporting ring 11 is simple and convenient to install. When the ring buckle part 1102 is inserted into the ring buckle groove 501 upward, the ring buckle part 1102 extrudes and opens the ring buckle groove 501, so as to make the ring buckle groove 501 elastically expand and deform. Figure 13 As shown in the figure, the lower end of the outer cover 8 is formed with an inner flange, as shown in the figure. Figure 9 The upper part of the cover body 51 is formed with a positioning ring groove 511, which is radially concave, as shown in the figure. Figure 2 The above-mentioned inner flange is adapted to buckle the positioning ring groove 511, so as to position the outer cover 8 and the valve cover 5 radially and axially, but the outer cover 8 can rotate relative to the valve cover 5, so when the valve handle 7 is rotated, the valve handle 7 drives the outer cover 8 to rotate through the window 801; the connection structure of the above-mentioned outer cover 8 and the valve cover 5 is simple and convenient for the installation of the outer cover 8. In the process of assembling the outer cover 8 and the valve cover 5, the outer cover 8 is pressed downward, the valve cover 5 extrudes and opens the lower end of the outer cover 8, so as to make the lower end of the outer cover 8 elastically expand and deform, so that the above-mentioned inner flange can be moved to the position of the positioning ring groove 511, and then the lower end of the outer cover 8 elastically contracts and resets, so that the above-mentioned inner flange is inserted into the positioning ring groove 511 radially inward.

[0042] Further, as shown in the figure, Figure 1As shown, the bottle bottom 102 is formed with a gas injection hole which is closed by a rubber sealing plug 103.
