Description

Technical Field

[0001] This utility model relates to the field of ointment container technology, specifically a rotary balm paper tube. Background Technology

[0002] Currently, lipsticks, perfumes, and similar products are packaged and sold in containers, which are mostly made of plastic or metal. While plastic and metal are recyclable materials, a significant amount is still discarded, causing environmental problems. Manufacturers are researching how to partially replace plastic or metal with environmentally friendly materials to reduce environmental risks even when containers cannot be fully recycled after the product is used. Utility Model Content

[0003] The purpose of this invention is to provide a rotary perfume tube that can use environmentally friendly paper to replace some plastic or metal materials, thereby reducing environmental risks.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A rotary perfume tube includes a top cover, a cap, a screw, a piston, an inner bottle, a bottom tube, and an inner bottom cover. The bottom tube comprises an outer tube and an inner tube. One end of the outer tube has an inner stop ring, and one end of the inner tube has an annular limiting ring inserted into the outer tube and tightly fitted against the inner stop ring. The other end of the inner tube is located outside the outer tube. The inner bottle is cylindrical and housed within the inner tube. One end of the inner bottle is tightly fitted against the limiting ring. One end of the inner side of the inner bottle has an inwardly protruding annular screw ring, and the inner side of the inner bottle also has an inwardly protruding anti-rotation rib aligned with the central axis of the inner bottle. The anti-rotation rib extends from the annular screw ring to the other end of the inner side of the inner bottle. The screw includes a stud and a cylindrical head. One end of the stud is connected to the cylindrical head. The outer circumferential surface of the cylindrical head has a screw groove that mates with the annular screw ring. The screw is rotatably connected to the annular screw ring of the inner bottle through the screw groove. The piston is cylindrical. The center of the piston has a threaded hole that mates with the stud. The outer circumferential surface of the piston has an anti-rotation groove that mates with the anti-rotation rib. The piston is threadedly connected to the stud and movably connected to the anti-rotation rib. The cover is located at the exposed end of the inner tube. The top cover of the paper tube is located on the outside of the inner tube and close to one end of the outer tube. The inner bottom cover is inserted into the inner tube from the end with the annular limiting ring and is connected to the cylindrical head of the screw.

[0005] This design uses some paper components. After all components are assembled, the paste is inserted through the outside of the screw and piston, inside the inner bottle. When the paste is needed, open the top cover and the cover plate of the paper tube, rotate the bottom cover, and the bottom cover will drive the cylindrical head of the screw to rotate together. When the cylindrical head of the screw rotates, the stud also rotates together. The middle part of the piston is threadedly connected to the stud, but the stop groove on the outside of the piston cooperates with the anti-rotation rib. When the inner bottle is stationary, the piston does not rotate with the stud but moves in a straight line along the anti-rotation rib, thereby pushing the paste outward for easy use. After use, rotate the bottom cover in the opposite direction to drive the piston to move in the opposite direction. After it moves into place, the cover plate can be used to push the paste back into the inner bottle, and then the top cover of the paper tube can be closed.

[0006] In a preferred embodiment of this invention, the outer tube and inner tube, and the inner tube and inner bottle are connected by adhesive. In this embodiment, the outer tube, inner tube, and inner bottle are all made of paper, and can be firmly connected after being glued together using environmentally friendly adhesive.

[0007] In a preferred embodiment of this invention, the connecting end between the stud and the cylindrical head of the screw is provided with a positioning block whose outer diameter is larger than that of the stud, and the piston is initially positioned close to the positioning block. The positioning block in this embodiment primarily determines the position of the piston, providing bottom support for the paste of a defined size.

[0008] As a preferred embodiment of this utility model, the inner bottom cover has a cylindrical end at one end, a manual head at the other end, and a retaining ring in the middle. The cylindrical head of the screw has a rotating groove that mates with the cylindrical end. The outer surface of the cylindrical end and the inner surface of the rotating groove have mutually engaging rotating tooth grooves or teeth. The rotating groove has a retaining groove that mates with the retaining ring. The manual head is a manual knob or a manual rotating blade. To facilitate manual operation, the inner bottom cover of this embodiment can be equipped with a manual head, such as a manual knob or a manual rotating blade, that allows for easy rotation. The inner bottom cover is tightly fitted to the rotating groove and rotating teeth of the cylindrical head of the screw, or it can be fixed with environmentally friendly adhesive.

[0009] As a preferred embodiment of this utility model, the top cover of the paper tube is closed at one end and has an inner top cover inside the closed end. The cover includes an inner ring cover and a protrusion. The bottom end of the inner ring cover mates with the port of the inner tube body, and the top end of the inner ring cover mates with the inner top cover. The protrusion is located inside the inner ring cover and protrudes outward. The protrusion of the cover in this embodiment allows it to hold more paste. The fit between the top cover of the paper tube and the cover provides a better seal and prevents excessive evaporation of the paste.

[0010] As a preferred embodiment of this utility model, the top cover, cover plate, inner bottle, and bottom tube of the paper tube are all environmentally friendly paper products. The top cover, cover plate, inner bottle, and bottom tube of this embodiment are made of environmentally friendly paper. Other components can also be made of environmentally friendly paper, provided production conditions permit, to completely solve the environmental problems of the container.

[0011] Existing commercially available perfume balms all use plastic parts and are divided into three sections. This design uses environmentally friendly paper tubes instead, and the shape is divided into two sections. The balm is dispensed by rotating the inner cap at the bottom. Compared with existing technologies, this invention is more environmentally friendly and easier to use. Attached Figure Description

[0030] The top cover 1, cover plate 2, inner bottle 5, and bottom tube 6 of the paper tube are all environmentally friendly paper products.

[0031] The usage process of this utility model is as follows: During the bottle assembly process, the screw 3, with its cylindrical head 32, is pressed down from above the inner bottle 5. The screw groove 33 engages with the annular screw protrusion 51 of the inner bottle 5, ensuring proper engagement. The screw 3 rotates smoothly without interference. The piston 4, with its threaded hole 41, engages with the screw 3, with its stud 31, rotating counterclockwise until it is firmly attached to the positioning block 34. The piston 4, with its anti-rotation groove 42, engages with the anti-rotation rib 52 of the inner bottle 5, ensuring a tight fit without interference. The outer diameter of the inner bottle 5 matches the inner diameter of the inner tube body 62 of the paper tube bottom tube 6. The glue is applied to the inner bottle 5 and the bottom of the inner tube 5 is pressed into place at one end of the annular limiting ring 64. The cap 2 is pressed in from above the inner bottle 5 and downwards. The bottom end of the inner ring cap 21 of the cap 2 is press-fitted into the port of the inner bottle 5 and pressed into place. The top cap 1 of the paper tube is pressed in from above the cap 2 and downwards. The inner top cap 11 of the top cap 1 is pressed into place at the top end of the inner ring cap 21 of the cap 2. The port of the top cap 1 of the paper tube is pressed into place at the port of the outer tube 61 of the bottom tube 6, thus completing the bottle assembly.

[0032] The assembly process involves inserting the inner bottom cover 7 into the bottle assembly from bottom to top. The rotating tooth groove of the inner bottom cover 7 engages with the rotating tooth of the cylindrical end 71 to prevent rotation. The retaining ring 73 of the inner bottom cover 7 engages with the retaining groove in the rotating groove 35 of the screw cylindrical head 32 to restrict the movement between the inner bottom cover 7 and the screw cylindrical head 32. The assembly of the finished product is completed when the top of the inner bottom cover 7 is pressed into place with the rotating groove 35.

[0033] The paste is filled or directly placed into the inner bottle 5, with the bottom tightly against the top of the piston 4. When the paste is needed, open the top cover 1 and the cover plate 2 of the paper tube, and rotate the inner bottom cover 7. The inner bottom cover 7 drives the screw cylindrical head 32 to rotate together. When the screw cylindrical head 32 rotates, the stud 31 also rotates together. The middle part of the piston 4 is threadedly connected to the stud 31, but the anti-rotation groove 42 on the outside of the piston 4 cooperates with the anti-rotation rib 52 on the inside of the inner bottle 5. When the inner bottle 5 is stationary, the piston 4 does not rotate with the stud 31 but moves in a straight line along the anti-rotation rib 52, thereby pushing the paste outward for easy use. After use, rotate the inner bottom cover 7 in the opposite direction to drive the piston 4 to move in the opposite direction. After it moves into place, the paste can be pushed back into the inner bottle 5 with the cover plate 2, and then the top cover 1 of the paper tube is closed.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
