Description

Pressing gland type gel / cream packaging tube TECHNICAL FIELD

[0001] The present application relates to a packaging tube, in particular to a pressing gland type gel / cream packaging tube. BACKGROUND

[0002] In the industry and medical industry, paste, gel-like objects are usually packaged using a packaging tube. In the prior art, the bottle opening of the gel / cream product packaging bottle generally adopts a screw cap, a pull ring or is broken. This type of product packaging needs to be operated with both hands during opening. When a single arm is injured or in other special situations, it cannot be operated with one hand by one person, and it is not suitable for use in emergency situations.

[0003] Therefore, there is an urgent need for a pressing gland type gel / cream packaging tube that can be broken with one hand without being broken by mistake, and can be used in various special situations. SUMMARY

[0004] In order to solve the above technical problems, the present application improves the prior art and optimizes the packaging tube. The specific scheme is as follows:

[0005] A pressing gland type gel / cream packaging tube, characterized in that the packaging tube comprises a tube body, a nozzle and a gland.

[0006] The tube body is provided with a transition pipe; the tube body and the nozzle are connected through the transition pipe; the nozzle is provided with a reinforcing rib; and the nozzle and the gland are provided with a breakable groove.

[0007] Further, the reinforcing rib is an arc-shaped protrusion around the outside of the nozzle. The reinforcing rib can be a circular ring around the nozzle, or a plurality of circular arcs around the nozzle, and all the circular arcs are located on the same horizontal plane. This design can strengthen the pressure resistance of the nozzle and reinforce the strength of the tube shoulder to prevent breakage during mold removal during production.

[0008] Further, the gland is also provided with a handle vertically, which is easy to press with one hand. At the same time, the gland is a symmetrical structure, so that the object can maintain its shape when subjected to multiple forces.

[0009] Preferably, the handle on the gland is small and beautiful in shape, which conforms to the human finger ergonomics principle. It is easy to operate, and when pressed with one hand, the finger can better fit the handle, making it easier to bear force, facilitating one-handed breaking, and being suitable for use in special situations.

[0010] Further, the nozzle is also provided with a liquid outlet hole, and the liquid outlet hole is rectangular or strip-shaped in cross section.

[0011] Preferably, the gel / cream can be quantitatively and uniformly extruded from the liquid outlet hole.

[0012] Further, the transition pipe is frustoconical. The frustoconical transition pipe has good structural stability and can withstand large pressure and tension.

[0013] Further, the breakable groove is centrally symmetrically distributed around the liquid outlet hole.

[0014] Preferably, the breakable groove is a fracture, which is open or semi-open. This design is flexible and can be adjusted according to different needs and use scenarios.

[0015] Further, the pipe shoulder is injection molded using special PE material, which can meet the use in high-altitude, high-humidity, high-temperature, low-temperature and extremely cold climate conditions.

[0016] Further, the pipe body is connected with the transition pipe at the pipe shoulder.

[0017] Further, the pipe body is made of aluminum plastic sheet material, and the material and wall thickness of the transition pipe are the same as those of the pipe body.

[0018] Preferably, the aluminum foil of the outer layer of the aluminum plastic sheet is thick and has good stiffness, which is beneficial to single-handedly holding the pipe and breaking it. Moreover, the aluminum plastic sheet has good aroma retention, light shielding and heat shielding properties, and good corrosion resistance, and the inner layer of the aluminum plastic sheet is PE film material, which does not change the content.

[0019] The pressing gland type gel / cream packaging tube of the present application adopts the design of a pipe body, a nozzle and a pressing gland. The frustoconical transition pipe is used to connect the pipe body and the nozzle, and the reinforcing rib is added in the nozzle material, so that the size of the liquid outlet hole is basically stable during the extrusion of the gel / cream product, the extrusion amount can be controlled, and the gel / cream accumulation during use is prevented, which affects the use effect.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] 1. The present application provides a pressing gland type gel / cream packaging tube, which can meet the needs of single-person self-rescue in special emergency situations, can be broken and used by single hand, and has simple structure and high operability.

[0022] 2. The design of the reinforcing rib of the pressing gland type gel / cream packaging tube nozzle of the present application can reinforce the strength of the pipe shoulder and prevent the pipe shoulder from being broken during the production process.

[0023] 3. The pressing gland of the pressing gland type gel / cream packaging tube of the present application can be opened by single-handed pressing, which conforms to the principle of human finger engineering. Moreover, it is suitable for use in special scenarios.

[0024] 4. The tube body of the pressing gland type gel / cream packaging tube is made of an aluminum plastic sheet, the outer layer of which is made of an aluminum foil with higher thickness, and has good stiffness, which can provide sufficient support for breaking, and the inner layer is made of PE film material, which will not change with the content. The tube shoulder is made of PE mixed casting, which is suitable for use in harsh climate conditions. BRIEF DESCRIPTION OF DRAWINGS
