Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a hand cream packaging bottle with easily controllable extrusion volume. Background Technology

[0002] Hand cream is a skin care product that can heal and smooth cracked and dry skin, effectively preventing and treating rough, dry, and cracked hands in autumn and winter. Currently, most hand creams are packaged in tubes, which are easy to squeeze out. As shown in Chinese utility model patent application number CN202421273345.X (authorization announcement number CN222409266U), "A Packaging Tube", the tube includes a tube body, one end of which is glued together to form a closed end, and the other end is provided with a cap with a dispensing hole. The cap is provided with a seal to prevent the contents of the tube from leaking out of the dispensing hole when the tube is not in use.

[0003] While the aforementioned tube can package hand cream, the amount of cream dispensed from the nozzle is often uncontrollable. In actual use, if the user applies significant pressure, more hand cream will be dispensed than needed, resulting in waste and affecting the effectiveness of the packaging. Therefore, further improvements to the hand cream packaging are necessary. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a hand cream packaging bottle with a reasonable structure that can avoid excessive squeezing out, in view of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the hand cream packaging bottle with easily controllable extrusion volume includes a tube body and a cap body for containing the contents. The lower end of the tube body is provided with a tube opening. The cap body and the tube opening are detachably connected. The characteristic is that: the tube opening is provided with a liquid outlet head made of soft rubber material. The upper end of the liquid outlet head is installed inside the tube opening, and the lower end of the liquid outlet head is exposed outside the tube opening. The lower end face of the liquid outlet head is provided with a liquid outlet hole for the contents to flow out. The hole wall of the liquid outlet hole extends upward and is located inside the liquid outlet head. The inner diameter of the hole wall gradually decreases from bottom to top, so that the diameter of the liquid outlet hole gradually decreases from bottom to top.

[0006] Furthermore, the lower end face of the liquid outlet head is inclined. This configuration allows the lower end face of the liquid outlet head to better fit with the wall of the liquid outlet hole, i.e., the angle between the lower end face of the liquid outlet head and the wall of the liquid outlet hole is an acute or obtuse angle, which facilitates deformation of the hole wall to reduce the diameter of the liquid outlet hole.

[0007] Furthermore, an insert is fixedly embedded inside the cap, and the insert contains a plug corresponding to the liquid outlet. When the cap is installed on the tube opening, the plug can be inserted into the liquid outlet to block it; when the cap is removed from the tube opening, the plug can be removed from the liquid outlet to open it. This design allows the plug to block or open the liquid outlet through the detachable fit between the cap and the tube, thus preventing the hand cream bottle from leaking out due to compression in a backpack or during transportation, and also preventing the contents from leaking out of the liquid outlet when the bottle is inverted, thereby ensuring the effectiveness of the hand cream bottle.

[0008] Furthermore, the cap includes a metal outer shell and an insert located within the outer shell. The outer shell has an inner cavity for securing the insert, and the insert has a mounting cavity for inserting a tube opening and a liquid outlet head. The plug is disposed at the bottom of the mounting cavity. This design facilitates the manufacture of the cap and also makes it easier to install the cap onto the tube.

[0009] Furthermore, the bottom of the mounting cavity protrudes upward to form a plug, the outer diameter of which gradually increases from top to bottom. With the cover installed on the pipe opening, the plug is inserted into the liquid outlet hole, causing the hole wall to deform and thus blocking the outlet hole. This design allows the plug to better fit with the hole wall, resulting in a better sealing effect.

[0010] Furthermore, the outer wall of the tube opening is provided with external threads, and the inner wall of the mounting cavity is provided with internal threads that are compatible with the external threads, so that the cap and the tube opening can be detachably connected. The cap and tube of this hand cream packaging bottle are detachably connected by threads.

[0011] Furthermore, the bottom of the outer casing has a base with a flat bottom surface, which allows the liquid outlet of the tube to be placed downwards. This base design facilitates inverting the tube, allowing the hand cream bottle to be placed upside down on a table, and the stopper in the cap prevents leakage of contents from the liquid outlet.

[0012] Furthermore, the outer casing also includes a spherical handle located above the base, the outer diameter of which is smaller than that of the base. This handle design allows the user to easily grip and rotate it, enabling the cover and tube to be installed or disassembled. The smaller size of the handle compared to the base ensures that the handle does not interfere with the tube being placed upside down on a table using the base.

[0013] Compared with the prior art, the advantages of this utility model are as follows: The hand cream packaging bottle utilizes the wall of the dispensing hole to control the amount of liquid extruded. That is, when the user applies a large force to squeeze the tube, a large amount of contents is forced downwards against the wall of the dispensing head. Since the dispensing head is made of soft rubber material and has a certain degree of elasticity, the large amount of contents pressing against the wall of the dispensing hole will cause the wall of the dispensing hole to move inwards, that is, the diameter of the dispensing hole will be further reduced, thereby limiting the amount of contents extruded from the dispensing hole. Therefore, the structure of this hand cream packaging bottle is reasonable, which can control the amount of contents extruded, avoid excessive extrusion and waste, and improve the use effect of the hand cream packaging bottle.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-4 The image shown is the preferred embodiment of this utility model.

[0020] like Figure 3 and Figure 4 As shown, the hand cream packaging bottle of this embodiment includes a tube body 1, a cap body 2, and a dispensing head 3. The upper ends of the tube body 1 are glued together to form a closed end, and the lower end of the tube body 1 is provided with a tube opening 11. The tube body 1 is used to contain the contents, and in this embodiment, it is used to contain a paste-like hand cream. The dispensing head 3 of this embodiment is located at the tube opening 11. The dispensing head 3 is made of soft rubber material. The upper end of the dispensing head 3 is fixed inside the tube opening 11, and the lower end of the dispensing head 3 is exposed outside the tube opening 11. The lower end face of the dispensing head 3 is inclined and has a dispensing hole 31 for the contents to flow out. That is, the dispensing hole 31 communicates with both the inside and outside of the tube body 1. The hole wall 311 of the dispensing hole 31 extends upward and is located inside the dispensing head 3. The inner diameter of the hole wall 311 gradually decreases from bottom to top, so that the diameter of the dispensing hole 31 gradually decreases from bottom to top, allowing the dispensing hole 31 of the dispensing head 3 to control the amount of hand cream dispensed.

[0021] like Figure 1 and Figure 2 As shown, in this embodiment, the cover 2 and the opening 11 of the tube 1 are detachably connected. The cover 2 includes a shell 22 made of metal and an insert 21 located inside the shell 22. The shell 22 has an inner cavity for embedding and fixing the insert 21. The insert 21 is embedded and fixed inside the shell 22, so that the insert 21 and the shell 22 form an integral structure. The insert 21 in this embodiment has a mounting cavity 212 for inserting the tube opening 11 and the liquid outlet head 3. The bottom of the mounting cavity 212 is provided with an upwardly protruding plug 211 corresponding to the liquid outlet 31. The outer diameter of the plug 211 gradually increases from top to bottom. When the cover 2 is installed on the tube opening 11, the plug 211 is inserted into the liquid outlet 31. The plug 211 causes the hole wall 311 of the liquid outlet 31 to deform, thereby blocking the liquid outlet 31. When the cover 2 is removed from the tube opening 11, the plug 211 can be removed from the liquid outlet 31 to open the liquid outlet 31. Thus, by utilizing the detachable connection between the cover 2 and the tube 1, the plug 211 can block or open the liquid outlet 31.

[0022] like Figure 3 and Figure 4 As shown, the outer wall of the tube opening 11 in this embodiment is provided with an external thread 111, and the inner wall of the mounting cavity 212 is provided with an internal thread 213 that matches the external thread 111, so that the cover 2 and the tube opening 11 of the tube body 1 can be detachably connected. In addition, the bottom of the outer shell 22 in this embodiment has a base 221, the bottom surface of which is flat. The base 221 allows the outlet hole 31 of the tube body 1 to be placed downwards, that is, the tube body 1 can be placed upside down on the table with the help of the base 221 of the cover 2. The outer shell 22 also includes a handle 222 located above the base 221. The handle 222 is spherical and makes it easy for the user to hold the cover 2 and apply force to the cover 2 to install or detach the cover 2 from the tube body 1. The outer diameter of the handle 222 is smaller than the outer diameter of the base 221, so that the handle 222 will not affect the tube body 1 being placed upside down on the table with the help of the base 221.

[0023] The workflow of this embodiment is as follows: With the cover 2 installed on the tube 1, the plug 211 can be inserted into the liquid outlet 31 to block the liquid outlet 31. At this time, the tube 1 can be placed upside down on the table with the help of the base 221 of the cover 2. Figure 1 and Figure 3 As shown; when the user needs to open the liquid outlet 31, the user first grasps the handle 222 of the cap 2 and rotates it. Utilizing the threaded connection between the internal thread 213 of the cap 2 and the external thread 111 of the tube 1, the cap 2 is removed from the tube 1. At this time, as the cap 2 is removed from the tube 1, the plug 211 inside the cap 2 gradually moves away from the liquid outlet 31, thus connecting the liquid outlet 31 to the outside, i.e., opening the liquid outlet 31. The user can then use the liquid outlet 31 to squeeze out the contents of the tube 1, such as... Figure 2 As shown, if the user applies a large force to squeeze the tube 1, a large amount of hand cream will be squeezed downwards into the hole wall 311 located in the dispensing head 3, causing the hole wall 311 to move inwards, thereby further reducing the diameter of the dispensing hole 31, thus restricting a large amount of hand cream from being squeezed out of the dispensing hole 31.
