Description

Technical Field

[0001] This application relates to the technical field of dispensing devices, specifically to a press-type liquid dispensing device. Background Technology

[0002] Instant glue is a type of adhesive that can cure in a short time, such as 502 glue on the market. Currently, instant glue bottles generally consist of a bottle body with a conical dispensing tube at the top. The top of the dispensing tube is sealed and then covered with an outer cap. When glue needs to be dispensed, the top of the dispensing tube is cut off with scissors, and then the bottle body is squeezed to dispense the glue. With this type of glue bottle structure, the squeezing process involves direct hand action on the bottle body containing the glue, which is relatively laborious.

[0003] To improve the difficulty of pressing in the above-mentioned structure, existing technology, such as CN202120476999.2, discloses a press-type dispensing device. This solution covers the glue bottle with a sleeve, and the bottom of the sleeve has an opening. The pressing component with a pressing handle is connected to the sleeve through the opening, and the glue bottle is pressed by pressing the handle to dispense glue, achieving a labor-saving effect. However, although this structure can achieve the effect of labor-saving pressing, when changing or fixing the internal glue bottle, it is necessary to repeatedly disassemble and assemble the pressing component with the pressing handle with the sleeve. In this process, because the base of the pressing component is small and not easy to apply force, the force is mostly applied directly to the pressing handle, making assembly and disassembly cumbersome and laborious. More seriously, because the repeated assembly and disassembly process directly applies force to the pressing handle, the pressing handle is easily deformed or damaged under this force. This will lead to inaccurate glue dispensing or unusable situations in subsequent use of the pressing handle. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, this application provides a push-type liquid dispensing device that does not require the assembly and disassembly of the labor-saving handle, and does not require direct force to be applied to the labor-saving handle during the assembly and disassembly process, thereby enabling the labor-saving handle to maintain a stable state of use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a press-type liquid dispensing device, the structure of which includes an outer bottle body, an inner bottle body, and a cap body; the lower end of the outer bottle body is provided with an opening, the inner bottle body is fitted into the outer bottle body through the opening, and the cap body is placed on the outlet end of the inner bottle body; a force-saving handle is provided extending from the outer wall of the outer bottle body, and a detachable bottom cover is provided on the opening, the detachable bottom cover being connected to the opening for sealing the inner bottle body.

[0006] Using the above structure, this application achieves the assembly and disassembly of the inner bottle through a detachable connection between a separate detachable bottom cap and the outer bottle. Most importantly, this application places the effort-saving handle on the outer wall of the outer bottle, and the detachable bottom cap is an independent detachable structure. Therefore, during the disassembly and assembly of the detachable bottom cap relative to the outer bottle, no force needs to be applied directly to the effort-saving handle. Thus, the effort-saving handle can maintain its structural stability and will not deform or break. During use, it can maintain its pressing and dispensing effect on the inner bottle. Therefore, the amount of adhesive dispensed from the inner bottle, such as glue, can be controlled through the stable operation of the effort-saving handle. Furthermore, applying force to the inner bottle through the effort-saving handle is more labor-saving and convenient. In addition, because the effort-saving handle is attached to the side wall of the outer bottle, it achieves the effect of squeezing the inner bottle. At the same time, when the product is placed horizontally on a table, the handle can prevent the product from rolling off.

[0007] Furthermore, the outer wall of the outer bottle is provided with a perforated portion, through which the inner bottle is exposed. The perforated portion corresponds to the labor-saving handle, which can press against the outer wall of the outer bottle to squeeze out glue from the exposed inner bottle. With this structure, when the labor-saving handle is pressed close to the inner bottle, the perforated portion allows the handle to directly press against the inner bottle, making the glue dispensing easier and allowing for greater control over the depth of pressure to regulate the amount of glue dispensed.

[0008] Furthermore, the detachable bottom cap and the opening of the outer bottle are connected by a threaded connection. With this structure, the inner bottle can be inserted first through the opening at the lower end of the outer bottle, and then the independent detachable bottom cap can be screwed on to fix the inner bottle and limit its upper and lower positions. This threaded connection structure makes it more convenient to connect and disassemble the detachable bottom cap and the outer bottle, and the screwing force does not need to be applied directly to the force-saving handle, but can be applied directly to the bottle body of the outer bottle, maintaining the stability of the force-saving handle structure without deformation or damage.

[0009] Furthermore, the lower end of the detachable bottom cover is provided with a recessed groove, and a horizontal rib is provided in the groove. With this structure, the detachable bottom cover can be screwed in and out by holding the horizontal rib, making the operation more convenient and effortless.

[0010] Furthermore, the lower end of the horizontal rib does not protrude from the lower end of the groove; this structure ensures the flatness of the lower end of the detachable bottom cover, making the glue bottle stable as a whole.

[0011] Furthermore, the effort-saving handle and the outer bottle body are integrated into one piece. This structure can improve the firmness of the connection between the effort-saving handle and the outer bottle body, and even repeated pressing will not cause the effort-saving handle to detach from the outer bottle body.

[0012] Furthermore, the labor-saving handle includes a first pressing plate, the lower end of which is connected to the side wall of the outer bottle. A second pressing plate is provided on the inner side of the first pressing plate, and a conical pressing head is provided on the side of the second pressing plate facing the hollow part. The conical pressing head is used to abut against the inner bottle. With this structure, by pressing the first pressing plate with the hand, the conical pressing head of the second pressing plate is driven to squeeze the inner bottle, thereby dispensing glue. This conical pressing head structure has point contact with the inner bottle, making the pressing process more labor-saving and easier to control the depth of pressing to achieve effective control of the amount of glue dispensed.

[0013] Furthermore, an arc-shaped groove is provided at the connection between the first pressing plate and the outer bottle body, and the arc-shaped groove is recessed towards the bottom of the outer bottle body. With this structure, due to the setting of the arc-shaped groove, the process of pressing the labor-saving handle towards the inner bottle body is folded close to the outer bottle body at the arc-shaped groove, so pressing is more labor-saving, and it can also improve the restoring force of the labor-saving handle, avoiding breakage or failure of restoration due to repeated pressing.

[0014] Furthermore, the cap includes an inner cap and an outer cap, the inner cap being closed to the outlet end of the inner bottle, and the outer cap being closed to the outside of the inner cap; this structure can improve the sealing performance of the bottle and prevent the evaporation of the internal adhesive.

[0015] Furthermore, the inner cover is provided with a conical dispensing tube, and the upper end of the conical dispensing tube is provided with a sealing layer. The outer cover is provided with a pin on the side away from the sealing layer. With this structure, when it is needed, the outer cover is removed, and the side with the pin is aligned with the sealing layer and inserted to open the sealing layer and expose the dispensing port, without the need for cutting with scissors.

[0016] Furthermore, a sealing head is provided inside the outer cover near the sealing layer, and the sealing head is adapted to the glue outlet sealed by the sealing layer. With this structure, when the sealing layer is removed and the outer cover is not in use, the outer cover is screwed on, and the sealing head on the outer cover is inserted into the glue outlet to achieve resealing and prevent glue leakage. This avoids instant glue evaporation, and this resealing structure can reduce the contact area between the instant glue and the sealing head, preventing the outer cover from being over-adheded.

[0017] Furthermore, the inner wall of the outer bottle is provided with reinforcing ribs, which are interference-fitted with the inner bottle. This structure improves the strength of the outer bottle, protecting the inner bottle. The reinforcing ribs, along with the interference fit, also limit the vertical movement and horizontal rotation of the inner bottle.

[0018] Furthermore, a connector is provided on the side of the inner cap near the inner bottle body. The connector is used to insert into the opening of the inner bottle body and to make an interference fit with the opening. With this structure, after the inner cap is screwed onto the inner bottle body, the connector is inserted into the opening at the upper end of the inner bottle body and makes an interference fit with the opening to achieve a seal, preventing glue from leaking from here.

[0019] Furthermore, the outer bottle is cylindrical, which provides a better grip and user experience compared to the traditional flat instant adhesive inner bottle. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] As attached Figure 1-10As shown, this application discloses a press-type dispensing device for glue bottles. The structure of the glue bottle includes an outer bottle body 1, an inner bottle body 2, and a cap 3. An opening 101 is provided at the lower end of the outer bottle body 1. The inner bottle body 2 fits into the outer bottle body 1 through the opening 101. The cap 3 covers the outlet end of the inner bottle body 2. A force-saving handle 102 extends from the outer wall of the outer bottle body 1. A detachable bottom cap 4 is provided on the opening 101, and the detachable bottom cap 4 is connected to the opening 101 to seal the inner bottle body 2. Specifically, this press-type dispensing device is a double-layered container. The outer layer is the outer bottle body 1, with an opening 101 at the lower end and an outlet end for the inner bottle body 2 at the corresponding upper end. The extended opening structure allows the inner bottle 2 to fit into the outer bottle 1 through the opening 101. The opening 101 is then sealed by the detachable bottom cap 4 to fix the inner bottle 2 and limit its vertical movement. In addition, a labor-saving handle 102 extends outward from the side wall of the outer bottle 1. The glue is contained inside the inner bottle 2, and the glue outlet is sealed by screwing the cap 3 onto the outlet end of the inner bottle 2. One end of the labor-saving handle 102 is connected to the outer wall of the outer bottle 1, and the other end extends outward as a free end. This free end can be pressed against the outer bottle 1 until the labor-saving handle 102 abuts against the inner bottle 2 to expel the glue. The cap 3 and the inner bottle 2 can be connected by threads to achieve a sealed cap.

[0034] Using the above structure, this application achieves the assembly and disassembly of the inner bottle through a detachable connection between a separate detachable bottom cap and the outer bottle. Most importantly, this application places the labor-saving handle on the outer wall of the outer bottle, while the detachable bottom cap is an independent detachable structure, not connected to the labor-saving handle. Therefore, during the disassembly and assembly of the detachable bottom cap relative to the outer bottle, no force needs to be applied directly to the labor-saving handle. Thus, the labor-saving handle can maintain its structural stability and will not deform or break. During use, it can maintain its pressing and dispensing effect on the inner bottle. Therefore, the amount of adhesive dispensed from the inner bottle, such as glue, can be controlled through the stable operation of the labor-saving handle. Furthermore, applying force to the inner bottle through the labor-saving handle is more labor-saving and convenient. In addition, since the labor-saving handle is attached to the side wall of the outer bottle, it achieves the effect of squeezing the inner bottle. Simultaneously, when the product is placed horizontally on a table, the handle prevents the product from rolling off.

[0035] As attached Figure 1-2 , Figure 4 and Figure 6As shown, the outer wall of the outer bottle 1 described in this application is provided with a hollowed-out portion 103 (i.e., removing this part of the outer wall of the outer bottle 1 to expose the inner bottle 2 in this part). The inner bottle 2 is partially exposed through the hollowed-out portion 103. The hollowed-out portion 103 is correspondingly provided with the labor-saving handle 102 (i.e., the labor-saving handle 102 is positioned directly opposite the hollowed-out portion 103, so that after pressing the labor-saving handle 102, it can directly act on the exposed inner bottle 2 through the hollowed-out portion 103). The labor-saving handle 102 can press relative to the outer wall of the outer bottle 1 to squeeze out glue from the exposed inner bottle 2. With this structure, when the labor-saving handle is pressed close to the inner bottle, the hollowed-out portion allows the labor-saving handle to directly press on the inner bottle, making the glue dispensing easier and more convenient to control the depth of the press to control the amount of glue dispensed.

[0036] As attached Figure 4-5 As shown, the detachable bottom cap 4 described in this application is threadedly connected to the opening 101 of the outer bottle body 1; that is, an external thread is provided on the outer peripheral wall of the detachable bottom cap 4, and an internal thread is provided on the inner wall of the opening 101 at the lower end of the outer bottle body 1. With this structure, the inner bottle body 2 can be inserted into the opening 101 at the lower end of the outer bottle body 1, and then the detachable bottom cap 4 can be screwed to fix the inner bottle body 2 and limit its upper and lower positions. This threaded connection structure makes the connection and disassembly between the detachable bottom cap 4 and the outer bottle body 1 more convenient and less labor-intensive, without the need for violent disassembly or assembly. Moreover, the screwing force does not need to be applied directly to the force-saving handle 102, but can be applied directly to the bottle body of the outer bottle body 1, maintaining the stability of the force-saving handle 102 structure and preventing deformation or damage.

[0037] As attached Figure 3 , Figure 5 and Figure 9 As shown, the lower end of the detachable bottom cover 4 described in this application is provided with a recessed groove 401, and a horizontal rib 402 is provided in the groove 401. Specifically, the groove 401 is recessed towards the inner bottle body 2 to facilitate the placement of the hand when applying force. With this structure, the detachable bottom cover 4 can be screwed in and out by holding the horizontal rib 402, making the operation more convenient and labor-saving.

[0038] As attached Figure 3 As shown, the lower end of the horizontal rib 402 described in this application does not protrude from the lower end of the groove 401; that is, the horizontal rib 402 is recessed inside the groove 401. This structure ensures the flatness of the lower end of the detachable bottom cover 4, so that the press-type liquid dispensing device is placed stably as a whole.

[0039] As an example, the effort-saving handle 102 and the outer bottle body 1 described in this application are integrally formed, that is, they can be integrally formed by processes such as plastic injection molding. With this structure, the connection between the effort-saving handle 102 and the outer bottle body 1 can be strengthened, and even if pressed repeatedly, the effort-saving handle 102 and the outer bottle body 1 will not break or detach.

[0040] As attached Figure 1-6 As shown, the effort-saving handle 102 described in this application includes a first pressing plate 104. The lower end of the first pressing plate 104 is connected to the side wall of the outer bottle 1. A second pressing plate 105 is provided on the inner side of the first pressing plate 104. A conical pressing head 106 is provided on the side of the second pressing plate 105 facing the hollow part 103. The conical pressing head 106 is used to abut against the inner bottle 2. With this structure, by pressing the first pressing plate 104 with the hand, the conical pressing head 106 of the second pressing plate 105 is driven to squeeze the inner bottle 2, thereby dispensing glue. This structure of the conical pressing head 106 can achieve point contact between it and the inner bottle 2. Therefore, the pressing process is more effortless and it is easier to control the depth of the pressing to achieve effective and precise control of the amount of glue dispensed.

[0041] As attached Figure 1-2 As shown, an arc-shaped groove 107 is provided at the connection between the first pressing plate 104 and the outer bottle 1 described in this application. The arc-shaped groove 107 is recessed towards the bottom end of the outer bottle 1 (i.e., towards the opening 101 at the lower end of the outer bottle 1). With this structure, due to the setting of the arc-shaped groove 107, the effort-saving handle 102 can be easily folded along the arc-shaped groove 107 to approach the outer bottle 1 during the pressing process towards the inner bottle 2. Therefore, the pressing process is more effortless, and it also provides a certain deformation space for the effort-saving handle 102. In addition, it can improve the recovery force of the effort-saving handle 102 and avoid breakage or failure of recovery due to repeated pressing.

[0042] As attached Figure 1-5 , Figure 7-8 and Figure 10 As shown, the cap 3 described in this application includes an inner cap 301 and an outer cap 302. The inner cap 301 is closed to the outlet end of the inner bottle 2, and the outer cap 302 is closed to the outside of the inner cap 301. Specifically, the inner cap 301 is first screwed onto the outlet end of the inner bottle 2, and then the outer cap 302 is screwed onto the outside of the inner cap 301. This structure can improve the sealing performance of the bottle and prevent the evaporation of the internal glue. When in use, the outer cap 302 is removed, and the inner cap 301 is used directly as a glue dispensing tube.

[0043] As attached Figure 2-5As shown, the inner cover 301 of this application is provided with a conical glue dispensing tube 303, and the upper end of the conical glue dispensing tube 303 is provided with a sealing layer 304 (the sealing layer 304 can be made of plastic film, etc., to seal the glue inside the inner bottle 2, and is punctured when used). The outer cover 302 is provided with a pin 305 on the side away from the sealing layer 304 (see details). Figure 2-3 As shown, when the outer cover 302 is fitted over the inner cover 301, the ejector pin 305 is facing upwards and outwards. With this structure, when needed, the outer cover 302 is removed, and one end of the ejector pin 305 is aligned with the sealing layer 304 and inserted to open the sealing layer 304 and expose the glue outlet, without the need for cutting with scissors or other tools.

[0044] As attached Figure 2-3 , Figure 10 As shown, a sealing head 306 is provided inside the outer cover 302 of this application, near the sealing layer 304. The sealing head 306 is adapted to the glue outlet sealed by the sealing layer 304. The sealing head 306 and the ejector pin 305 are arranged opposite each other along the axial direction of the outer cover 302. With this structure, when the sealing layer 304 is removed and not in use, the outer cover 302 is screwed on, and the sealing head 306 on the outer cover 302 is inserted into the glue outlet to achieve resealing and prevent glue leakage. This structure can avoid instant glue evaporation, and this resealing structure can reduce the contact area between the instant glue and the sealing head, avoid the outer cover being over-adheded, and make it easier to open.

[0045] As attached Figure 4-6 As shown, the inner wall of the outer bottle 1 described in this application is provided with reinforcing ribs 108, and the reinforcing ribs 108 and the inner bottle 2 are interference-fitted. Specifically, multiple reinforcing ribs 108 are provided along the axial direction on the inner wall of the outer bottle 1, and the thickness direction of the reinforcing ribs 108 extends radially inward. When the inner bottle 2 is fitted into the outer bottle 1, the outer wall of the inner bottle 2 and the reinforcing ribs 108 can achieve an interference fit. With this structure, the strength of the outer bottle 1 can be improved, thus protecting the inner bottle 2. Moreover, the setting of the reinforcing ribs 108, which achieves the interference fit of the inner bottle 2, can also play a certain limiting role in the vertical movement and horizontal rotation of the inner bottle 2, thereby improving the stability during use.

[0046] As attached Figure 2-3 , Figure 5 and Figure 8As shown, the inner cap 301 of this application is provided with a connector 307 on the side near the inner bottle 2. The connector 307 is used to insert into the opening (the glue outlet on the inner bottle 2) on the inner bottle 2 and to make an interference fit with the opening (i.e., the two are tightly fitted to achieve a sealing effect). With this structure, after the inner cap 301 is screwed onto the inner bottle 2, the connector 307 is inserted into the opening at the upper end of the inner bottle 2 and makes an interference fit with the opening to achieve a seal, preventing glue from leaking from here.

[0047] As attached Figure 1 , Figure 4-5 As shown, the outer bottle 1 described in this application is cylindrical. The outer bottle 1 of this application adopts a cylindrical design, which provides a stronger grip and a better user experience compared to the traditional flat instant glue bottle. The inner bottle 2 is also a cylindrical structure that is adapted to the outer bottle 1.

[0048] On the outer wall of the outer cover 302 and the inner cover 301 of this application, anti-slip ribs can be provided at the screwing position to facilitate screwing force.

[0049] The working principle and process of the press-type liquid dispensing device described in this application are as follows: First, the inner bottle 2 is inserted into the outer bottle 1 through the lower opening 101. Then, the detachable bottom cap 4 is screwed into the lower opening 101 of the outer bottle 1, thereby pushing the inner bottle 2 upward so that the outlet end of the upper part of the inner bottle 2 extends out of the outer bottle 1. Then, the inner cap 301 is screwed onto the thread on the outside of the outlet end of the inner bottle 2, thus connecting the inner bottle 2 and the outer bottle 1. A connector 307 is provided between the inner cap 301 and the opening of the inner bottle 2, as detailed in the appendix. Figure 2-3As shown, the connector 307 is inserted into the opening of the inner bottle 2 after the inner cover 301 and the inner bottle 2 are screwed together. The fit between the connector and the opening is interference-fitted to prevent glue leakage. Then, the outer cover 302 is screwed onto the outside of the inner cover 301 to complete the overall assembly of the device. Furthermore, the glue outlet at the upper end of the inner bottle 2 is sealed with a sealing layer 304 to seal the glue inside the inner bottle 2. When needed, the outer cover 302 is screwed off the inner cover 301, and one end of the outer cover 302 with the ejector pin 305 is aligned with the sealing layer 304 to puncture it. Then, the glue is dispensed by pressing the handle 102 to squeeze the inner bottle 2 at the corresponding position of the perforated part 103. The amount of glue dispensed is controlled by adjusting the pressing depth of the handle 102. When not in use, the outer cover 302 is screwed back onto the outside of the inner cover 301, at which point the sealing head 306 inside the outer cover 302 is inserted into... The dispensing port on the inner cap 301 is sealed. The press-type dispensing device of this application features an independent, detachable bottom cap 4, which makes assembly and disassembly more convenient, quick, and effortless. The detachable bottom cap 4 is located within the lower opening 101 of the outer bottle 1, without affecting the overall appearance or stability of the device. If the glue in the inner bottle 2 runs out, only a new inner bottle 2 needs to be replaced for reuse with other components, saving costs. Furthermore, this application places the effort-saving handle 102 directly on the outer wall of the outer bottle 1 instead of on the detachable bottom cap 4. During the twisting process between the detachable bottom cap 4 and the outer bottle 1, the force does not directly act on the effort-saving handle 102, thus avoiding deformation or damage. This ensures the structural stability of the effort-saving handle 102, maintaining an effective pressing effect, and making pressing more effortless and convenient to operate.
