[0029] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0030] As shown in Figures 1-8 FIG.

[0031] a paste paper tube provided by the present utility model includes a tube cap 1, a middle bundle core 2, and a base 3; the middle bundle core 2 is fixed on the base 3, the tube cap 1 is buckled on the middle bundle core 2, and the base 3 is used to support the middle bundle core 2 and the tube cap 1;

[0032] The middle bundle core 2 includes a sleeve 201 and beads 202. A plurality of notches 203 are formed on the tube wall of the sleeve 201. The beads 202 are arranged inside the sleeve 201 and move up and down inside the sleeve 201. A paste 4 is fixed to the top of the beads 202;

[0033] A plurality of push buttons 5 are provided on the beads 202, and the push buttons 5 slide freely up and down along the notches 203.

[0034] In one embodiment of the present utility model, as Figures 1-8 shown, the barrel cover 1 is a slender cylindrical body, the top end of the barrel cover 1 is closed, which is used to prevent dust or foreign objects from entering the barrel cover 1 and contaminating the paste 4. When it is necessary to open the paste paper tube, pull out the barrel cover 1 with force outward. When it is necessary to close the barrel cover 1, snap the barrel cover 1 onto the middle core 2; the base 3 is a cylindrical structure with one end closed and the other end open. The open end of the base 3 is used for the middle core 2 to be inserted and fixed. The wall thickness of the base 3 is the same as that of the barrel cover 1, and the inner diameter of the barrel cover 1 is the same as the inner diameter of the base 3; the middle core 2 includes a sleeve 201 and beads 202. The bottom edge of the sleeve 201 is fixedly connected to the base 3. The outer diameter of the sleeve 201 is the same as the inner diameter of the base 3 or the inner diameter of the barrel cover 1, so that the outer wall of the sleeve 201 fits the inner surface of the base 3, increasing the connection area between the sleeve 201 and the base 3, and enabling the sleeve 201 to be stably connected inside the base 3. When the barrel cover 1 is snapped onto the middle core 2, there is friction between the inner wall of the barrel cover 1 and the outer surface of the sleeve 201, making the barrel cover 1 firmly snapped onto the middle core 2 and preventing the barrel cover 1 from falling off easily. It can only be opened by pulling out with force. Two notches 203 are formed on the barrel wall of the sleeve 201. The notches 203 are symmetrically distributed on both sides of the sleeve 201, and the bottom ends of the notches 203 extend into the base 3. The beads 202 are arranged inside the sleeve 201, and the paste 4 is fixed to the top of the beads 202. The beads 202 move up and down along the inner wall of the sleeve 201. Two push buttons 5 are provided on the beads 202. The number of push buttons 5 is the same as the number of notches 203. The push buttons 5 are arranged on both sides of the beads 202, and the position of the push buttons 5 on the beads 202 is adapted to the position of the notches 203 on the sleeve 201.

[0035] When using the paste paper tube of the present utility model, first open the barrel cover 1 with force to expose the middle core 2. The user pushes the push button 5 upward along the notch 203. The push button 5 drives the beads 202 to slide upward along the inner wall of the sleeve 201, and the paste 4 is exposed from the sleeve 201. After the paste 4 is applied, push the push button 5 downward. The push button 5 drives the beads 202 to slide downward along the inner wall of the sleeve 201, and the paste 4 enters the sleeve 201. Then snap the barrel cover 1 onto the middle core 2.

[0036] More preferably, the beads 202 include a top support 2021, a support column 2022 and a bottom support 2023. The support column 2022 is connected between the top support 2021 and the bottom support 2023. The paste 4 is fixed to the top support 2021, and the support column 2022 is a hollow body.

[0037] In one embodiment, as Figure 6 、 Figure 7 and Figure 8As shown, the bead 202 includes a circular top support 2021, a hollow support column 2022, and a bottom support 2023 connected to the bottom end of the support column 2022. The top support 2021 and the bottom support 2023 are respectively circular plates, and the diameters of the top support 2021 and the bottom support 2023 are both equal to the inner diameter of the sleeve 201, so that the top support 2021 and the bottom support 2023 move up and down along the inner wall of the sleeve 201, preventing the bead 202 from shaking during movement. The support column 2022 is a hollow body, further reducing the weight of the paste cartridge.

[0038] More preferably, the height of the bead 202 is equal to the distance between the top end of the notch 203 and the top end of the sleeve 201.

[0039] In one embodiment, as Figure 6 、 Figure 7 and Figure 8 shown, the height of the bead 202 is equal to the distance between the top end of the notch 203 and the top end of the sleeve 201. When there is less paste 4 remaining, push the push button 5 upward until the push button 5 abuts against the top end of the notch 203. At this time, the top support 2021 just extends out of the sleeve 201, and the remaining little paste 4 can be completely exposed out of the sleeve 201, avoiding waste, and the user does not need to damage the paste cartridge to use up the paste 4, which is economical and practical.

[0040] More preferably, the push buttons 5 are arranged on both sides of the bottom support 2023, and the push buttons 5 are crescent-shaped hard plates.

[0041] In one embodiment, as Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 shown, two push buttons 5 are symmetrically arranged on the edge of the bottom support 2023. The push buttons 5 are integrally formed with the bottom support 2023. The inner arc edge of the push button 5 is connected to the outer peripheral edge of the bottom support 2023. The diameter of the circle where the outer arc edge of the push button 5 is located is greater than the outer diameter of the base 3. The outer arc edge of the push button 5 protrudes from the outer surface of the sleeve 201 and extends to the outside of the base 3. When the cylinder cover 1 is closed, it drives the bead 202 to move downward, bringing the paste 4 back into the sleeve 201. On the other hand, it prevents the push button 5 from entering the base 3 and being unable to be pushed out.

[0042] More preferably, the notch 203 is long and strip-shaped, and is arranged along the generatrix direction of the sleeve 201.

[0043] In one embodiment, as Figure 5 shown, the notch 203 is a long strip-shaped structure opened on the cylinder wall of the sleeve 201. The long strip shape helps the smooth sliding of the bead 202 and improves the consumer experience. The notch 203 plays a limiting role on the push button 5, enabling the bead 202 to move along the axial direction of the sleeve 201.

[0044] More preferably, a frustum 6 is provided above the supporting block 2021.

[0045] In one embodiment, as Figure 6 , Figure 7 and Figure 8 shown, a frustum 6 is provided above the supporting block 2021. The frustum 6 is integrally connected to the supporting block 2021. The top end of the frustum 6 is inserted into the bottom end of the paste 4. The frustum 6 increases the contact surface area between the supporting block 2021 and the paste 4, enhances the adhesion between the paste 4 and the supporting block 2021, makes the paste 4 more stable in the supporting block 2021, and prevents the paste 4 from falling off or shifting due to movement or vibration.

[0046] The above embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of this invention patent shall be subject to the appended claims.
