Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of instant adhesives, and more specifically to a pen-shaped instant adhesive. Background Technology
[0002] Instant adhesives are a general term for a class of adhesives that achieve rapid curing through the reaction of cyanoacrylate with trace amounts of moisture. By adjusting the formula, they can cure within one second or withstand temperatures up to 120°C, with strengths exceeding 30 MPa. Currently, most instant adhesives on the market are bottled. When using them, the bottle must be squeezed to expel the adhesive from the nozzle. The amount of adhesive dispensed each time is difficult to control, and extreme care must be taken to avoid skin contact, as it may cause burns. After use, the adhesive left at the nozzle can easily come into contact with air and harden, potentially clogging the nozzle. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a pen-shaped instant adhesive that allows adhesive to be dispensed from the nozzle simply by pressing the pen tip and to be closed by releasing the pen tip. It is easy to operate and the amount of adhesive dispensed is easy to control.
[0004] The technical solution of this utility model is to provide a pen-shaped instant adhesive, including a grip, a pen barrel, and an elastomer. The instant adhesive is disposed inside the pen barrel, and the grip is sealed to the pen barrel. The elastomer is disposed inside the grip and communicates with the interior of the pen barrel. The elastomer includes an elastic telescopic section, one end of which is axially limited by the grip or pen barrel, and the other end is sequentially provided with a conical sealing section and a pressing section. The end of the grip is provided with an adhesive outlet. The elastic force of the elastic telescopic section causes the conical sealing section to seal the adhesive outlet, and the pressing section extends out of the adhesive outlet. Pressing the pressing section can cause the conical sealing section to disengage from the adhesive outlet.
[0005] Compared with the prior art, the pen-shaped instant adhesive of this utility model has the following advantages: Simply pressing the pressing section extending beyond the dispensing port into the grip causes the conical sealing section to disengage from the dispensing port, thus connecting the inside and outside of the dispensing port. The instant adhesive inside the pen can then flow out from the dispensing port, achieving dispensing. During this process, the elastic stretching section is compressed. Lifting up and releasing the pressing section causes the elastic stretching section to rebound, allowing the conical sealing section to re-seal the dispensing port, thus sealing the dispensing port and the entire pen-shaped instant adhesive of this utility model. Dispensing and sealing the dispensing port are very convenient, and the dispensing amount can be easily controlled by adjusting the pressing time of the pressing section.
[0006] Preferably, the inner diameter of the glue outlet is smaller than the major diameter of the conical sealing section, but larger than the minor diameter of the conical sealing section and the outer diameter of the pressing section. This structure positions the glue outlet of the conical sealing section at its center, facilitating an interference fit between the conical sealing section and the glue outlet, thus completely sealing the outlet.
[0007] Preferably, the pressing section is a second cylindrical section located at the small-diameter end of the conical sealing section, and a first cylindrical section is located at the large-diameter end of the conical sealing section, which is connected to the elastic telescopic section. This structure, with the second cylindrical section, facilitates the smooth entry and exit of the pressing section from the outlet; the first cylindrical section connected to the elastic telescopic section at the large-diameter end of the conical sealing section reduces the height of the conical sealing section and also facilitates the overall manufacturing of the elastic telescopic section.
[0008] Preferably, the lower part of the handle is provided with a tapered section, and the glue outlet is located at the small-diameter end of the tapered section. This structure can increase the contact area between the conical sealing section and the inner wall of the tapered section, thereby improving the sealing effect. During the glue dispensing process, the inner wall of the tapered section also helps to guide the instantaneous glue flow, increasing the glue dispensing volume and reducing problems such as glue jamming and insufficient glue dispensing volume.
[0009] Preferably, the upper part of the grip has a first sealing section, and the lower part of the pen barrel has a second sealing section. The first sealing section is fitted over the outside of the second sealing section with an interference fit. This structure is simple, facilitates the assembly of the grip and the pen barrel for sealing connection, and also prevents the user from easily separating the grip and the pen barrel, which could lead to glue leakage.
[0010] Preferably, a sealing rib is provided on the outer wall of the second tight-fitting section, and the sealing rib is interference-fitted with the inner wall of the first tight-fitting section. This structure improves the sealing performance at the connection between the grip and the pen barrel, and also increases the difficulty for the user to separate the grip from the pen barrel.
[0011] Preferably, the second contact section is provided with a first limiting step surface, and the end face of the first contact section abuts against the first limiting step surface. This structure limits the position of the interference fit between the grip and the pen barrel, preventing inadequate connection leading to poor sealing, and also preventing over-connection causing damage to the grip.
[0012] Preferably, the elastic telescopic section is provided with a second limiting step surface, and the end face of the second close contact section abuts against the second limiting step surface. This structure is simple and facilitates the axial limitation of the upper end of the elastic telescopic section by the pen barrel.
[0013] Preferably, a pen barrel connecting section is provided above the second limiting step surface, and the pen barrel connecting section is inserted into the inner side of the second tight-fitting section. This structure facilitates the assembly of the elastomer and the pen barrel, preventing the elastomer's movement on the pen barrel from affecting the assembly of the grip and the pen barrel.
[0014] Preferably, a pen cap is provided on the grip, which is detachably fitted onto the outside of the grip. A limiting protrusion is provided on the inner wall of the pen cap, and a snap-fit rib is provided on the outer wall of the grip. The pen cap is fitted onto the outside of the grip, and the limiting protrusion and snap-fit rib are engaged in a snap-fit connection. This structure is simple and allows for easy detachment of the pen cap onto the outside of the grip. Attached Figure Description

Furthermore, when expressions such as "...at least one" appear after a list of listed features, they modify the entire listed feature, not individual elements in the list.
[0021] like Figure 1 and Figure 2 As shown, the pen-type instant adhesive of this utility model includes a pen cap 1, a grip 2, a pen barrel 3, and an elastomer 4. Instant adhesive is disposed inside the pen barrel 3. The grip 2 is sealed to the pen barrel 3. The elastomer 4 is disposed inside the grip 2 and communicates with the interior of the pen barrel 3. The pen cap 1 is detachably sleeved on the outside of the grip 2.
[0022] The upper part of the grip 2 is provided with a first tight-fitting section 2-2, and the lower part of the pen barrel 3 is provided with a second tight-fitting section 3-1. A sealing rib 3-3 is provided on the outer side wall of the second tight-fitting section 3-1. The first tight-fitting section 2-2 is fitted onto the outer side of the second tight-fitting section 3-1 with an interference fit, and the sealing rib 3-3 is also interference-fitted with the inner side wall of the first tight-fitting section 2-2. The second tight-fitting section 3-1 is provided with a first limiting step surface 3-2, which abuts against the end face of the first tight-fitting section 2-2.
[0023] The inner wall of the pen cap 1 is provided with a limiting protrusion 1-1, and the outer wall of the grip 2 is provided with a snap-fit rib 2-1. The pen cap 1 is sleeved on the outer side of the grip 2, and the limiting protrusion 1-1 is snapped together with the snap-fit rib 2-1.
[0024] The elastic body 4 includes an elastic telescopic section 4-3, which is provided with a second limiting step surface 4-2. A pen barrel connecting section 4-1 is provided above the second limiting step surface 4-2. The pen barrel connecting section 4-1 is inserted into the inner side of the second close contact section 3-1. The second limiting step surface 4-2 abuts against the end face of the second close contact section 3-1, that is, the upper end of the elastic telescopic section 4-3 is axially limited by the pen barrel 3.
[0025] The lower end of the elastic expansion section 4-3 is provided with a first cylindrical section 4-4, a conical sealing section 4-5, and a second cylindrical section 4-6 in sequence. The first cylindrical section 4-4 is located at the large diameter end of the conical sealing section 4-5 and is directly connected to the elastic expansion section 4-3. The second cylindrical section 4-6 is located at the small diameter end of the conical sealing section 4-5.
[0026] The lower part of the grip 2 is provided with a tapered section 2-3, and the small-diameter end of the tapered section 2-3 is provided with an adhesive outlet 2-4. That is, the adhesive outlet 2-4 is located at the lower end of the grip 2. The inner diameter of the adhesive outlet 2-4 is smaller than the large diameter of the conical sealing section 4-5 but larger than the small diameter of the conical sealing section 4-5 and the outer diameter of the second cylindrical section 4-6. Due to the elastic force of the elastic telescopic section 4-3, the conical sealing section 4-5 seals the adhesive outlet 2-4, and the second cylindrical section 4-6 extends out of the adhesive outlet 2-4, becoming the pressing section.
[0027] By pressing the lower end of the pressing section, i.e. the second cylindrical section 4-6, which extends out of the glue outlet 2-4, into the grip 2, the conical sealing section 4-5 can be disengaged from the glue outlet 2-4, thereby connecting the inside and outside of the glue outlet 2-4. The glue inside the pen barrel 3 can then flow out from the glue outlet 2-4 to achieve glue dispensing. During this process, the elastic stretching section 4-3 is compressed.
[0028] When the lower end of the pressing section, i.e. the second cylindrical section 4-6, is lifted and released, the elastic telescopic section 4-3 can rebound, allowing the conical sealing section 4-5 to seal the glue outlet 2-4 again. With the glue outlet 2-4 sealed, the entire pen-shaped instant glue of this utility model is also sealed, and the instant glue inside the pen barrel 3 will not flow out.
[0029] The pen-shaped instant glue of this invention is very convenient to operate in terms of dispensing and sealing the dispensing port, and the amount of glue dispensed can be easily controlled by simply controlling the time of pressing the lower end of the second cylindrical section 4-6.
[0030] In other embodiments, the first cylindrical segment 4-4, used to connect the elastic telescopic segment 4-3 and the conical sealing segment 4-5, can be configured with other structures without affecting the use of the pen-shaped instant adhesive of this invention. The second cylindrical segment 4-6 can also be configured with other structures, as long as it can pass smoothly through the dispensing port 2-4.
[0031] In other embodiments, the sealing rib 3-3 may not be provided on the outer wall of the second tight-fitting section 3-1. The sealing connection requirement can be met simply by the first tight-fitting section 2-2 being sleeved on the outside of the second tight-fitting section 3-1 with an interference fit.
[0032] In other embodiments, the pen barrel connecting section 4-1 may not be provided on the elastomer 4. The elastomer 4 may be assembled into the grip 2 first, and then the grip 2 may be sealed together.
[0033] In other embodiments, the pen cap 1 and the grip 2 can be other detachable connection structures, such as the pen cap 1 being threaded onto the outside of the grip 2. When the pen-shaped instant adhesive of this utility model is not in use, the pen cap 1 only needs to protect the pressing section from being accidentally pressed.
[0034] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
