[0028] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0029] In the description of this application, it should be understood that the term "ring structure" used in this application refers to a structure that is generally ring-shaped. The ring structure can be continuous or composed of multiple discontinuous parts, such as the annular groove, the first annular protrusion, the second annular protrusion, etc. in the embodiments of this application.

[0030] The inventors discovered that in the category of emulsion packaging bottles, a certain structural strength is required, so a relatively rigid outer shell is used for packaging. However, relying solely on the accumulation of packaging results in excessive raw material input for the product, and the packaging is too heavy and cumbersome, thus reducing the user experience.

[0031] Based on this, such as Figure 1 , Figure 2 and Figure 9 As shown in the preferred embodiment of this application, an emulsion packaging bottle 1 includes: a tubular outer shell 11, an inner bottle 12, a pump head 13, and a pressure head 14. The tubular outer shell 11 includes a head 111 and a tail 112, with the tail 112 having a bottom opening. The inner bottle 12 includes a bottle mouth 121, a bottle body 122, a bottle bottom 123, and a first annular protrusion 124. The pump head 13 is fixed to the bottle mouth 121 and includes a straw 131 and a liquid outlet 132.

[0032] The tubular outer shell 11 has a hollow structure. The radial cross-sectional dimensions of the tubular outer shell 11 gradually increase from the first end 111 to the last end 112. The inner wall of the tubular outer shell 11 has an annular groove 113 located at the last end 112. The body 122 of the inner bottle 12 fits against the inner wall of the tubular outer shell 11, so that the inner bottle 12 is embedded in the tubular outer shell 11. The first annular protrusion 124 is provided on the body 122 near the bottom 123. The first annular protrusion 124 is used to engage with the annular groove 113. The diameter of the bottom opening is equal to the diameter of the bottom 123. The straw 131 extends into the inner bottle 12 through the bottle mouth 121. The pump head 13 is used to draw out the liquid in the inner bottle 12 through the straw 131 under pressure and pump it out through the outlet 132. The pressure head 14 is connected above the pump head 13. The inside of the pressure head 14 is provided with a pipe 141, which is aligned with the liquid outlet 132 to change the direction in which the liquid in the inner bottle 12 is pumped out.

[0033] The emulsion packaging bottle 1 in the application is mainly composed of an inner bottle 12 and a tubular outer shell 11. The tubular outer shell 11 is arranged in a structure gradually increasing from top to bottom. The bottle body 122 of the inner bottle 12 is attached to the inner wall of the tubular outer shell 11 (i.e. the bottle body 122 of the inner bottle 12 has the same shape as the inner wall of the tubular outer shell 11). Therefore, after the inner bottle 12 is assembled into the tubular outer shell 11, the tubular outer shell 11 can generate an acting force on the inner bottle 12 which is perpendicular to the bottle body 122 of the inner bottle 12. The acting force is obliquely downward, and the acting force has a downward component. Therefore, the tubular outer shell 11 can generate an acting force on the inner bottle 12 which is downward. Meanwhile, the cooperation of the annular groove 113 at the tail end 112 of the tubular outer shell 11 and the first annular protrusion 124 at the bottle body 122 close to the bottle bottom 123 can provide limiting in two directions, i.e. upward and downward. The downward limiting can provide an upward acting force on the inner bottle 12, and the downward acting force generated by the inner wall of the tubular outer shell 11 can firmly fix the inner bottle 12 in the tubular outer shell 11.

[0034] Since the tail end 112 of the tubular outer shell 11 has an open bottom, i.e. the tubular outer shell 11 has no bottom, the weight of at least one bottom shell is reduced. Further, since the tubular outer shell 11 has a hollow structure, the weight of the tubular outer shell 11 is further reduced. The weight of the tubular outer shell 11 is reduced, i.e. the weight of the emulsion packaging bottle 1 is reduced.

[0035] It can be understood that, in order to maintain a certain cooperation strength, the tubular outer shell 11 and the inner bottle 12 can be made of a hard material with a certain hardness, such as hard plastic, ceramic, glass, metal, etc. The specific material to be used is determined according to actual production requirements.

[0036] In an embodiment of the application, as shown in Figure 3 and Figure 4 The inner wall of the tubular outer shell 11 is further provided with a stepped protrusion 114. The stepped protrusion 114 is first bent towards the geometric center of the cross section of the tubular outer shell 11, and then bent towards the head end 111, thereby sequentially forming a tread 1141 and a kick 1142 of the stepped protrusion 114. The tread 1141 faces the tail end 112. The diameter of the bottle mouth 121 is smaller than the diameter of the bottle body 122. The intersection between the bottle body 122 and the bottle mouth 121 is provided with a mounting surface 126. The mounting surface 126 faces away from the tread 1141, and the mounting surface 126 and the tread 1141 are in contact with each other. The bottle mouth 121 is provided with a second annular protrusion 127. The distance between the second annular protrusion 127 and the mounting surface 126 is equal to the height of the kick 1142, so that the stepped protrusion 114 is clamped into the gap between the second annular protrusion 127 and the mounting surface 126.

[0037] Through the above scheme, the mounting surface 126 on the inner bottle 12 generates an upward force on the tread surface 1141 on the tubular shell 11, and the second annular protrusion 127 on the inner bottle 12 generates a downward force on the stepped protrusion 114 on the tubular shell 11. The directions of the two forces are opposite, further strengthening the assembly strength between the tubular shell 11 and the inner bottle 12. Since the stepped protrusion 114 is arranged near the head end 111 of the tubular shell 11, the cooperation structure of the stepped protrusion 114, the second annular protrusion 127 and the mounting surface 126 does not affect the cooperation structure of the first annular protrusion 124 and the annular groove 113 at the tail end 112. Therefore, the two cooperation structures can be used together to increase the assembly strength between the tubular shell 11 and the inner bottle 12 and achieve better assembly effect.

[0038] The inventor found that the continuous annular cooperation structure requires more force during assembly, has high assembly difficulty, and is prone to cracking.

[0039] To this end, as shown in the embodiment of the present application, Figure 5 the cross section of the tubular shell 11 is a regular polygon, and the number of surfaces of the inner wall of the tubular shell 11 is equal to the number of sides of the regular polygon.

[0040] The cross-sectional shape of the tubular shell 11 is polygonal, which improves the holding feeling. Compared with a circular shape, the polygonal shape of the shell can effectively improve the anti-skid performance and be more in line with ergonomics during holding, making it more convenient to use the lotion.

[0041] On the basis of this scheme, in an embodiment, as shown in the embodiment of the present application, Figure 5 the stepped protrusion 114, the first annular protrusion 124 or the second annular protrusion 127 is disconnected at the connection between adjacent two surfaces of the inner wall. In the example shown in the figure, the tubular shell 11 is a regular hexagon, and the stepped protrusion 114 is divided into six discontinuous segments, which are distributed on one side of the regular hexagon. Similarly, other annular structures such as the first annular protrusion 124 and the second annular protrusion 127 can also adopt similar structures and be disconnected at the connection between adjacent two surfaces of the inner wall.

[0042] Through the above scheme, the annular structure between every two side surfaces of the inner wall is disconnected. Therefore, during assembly, the stress generated by the extrusion between the assembly structures can be released to the disconnected gap, so that the annular structures such as the stepped protrusion 114, the first annular protrusion 124 and the second annular protrusion 127 are not prone to breakage during assembly, and the assembly difficulty of the tubular shell 11 and the inner bottle 12 is also reduced.

[0043] In order to further reduce the assembly difficulty and improve the structural strength, in an embodiment of the present application, as shown in the embodiment of the present application, Figure 5As shown, the inner wall of the tubular shell 11 is provided with a plurality of first guide grooves 115, which extend from the leading end 111 to the trailing end 112. The length of the first guide grooves 115 is equal to the length of the bottle body 122, and the plurality of first guide grooves 115 are uniformly distributed along the geometric center of the cross section of the tubular shell 11.

[0044] As shown, the bottle body 122 is provided with a plurality of first guide strips 125, which are matched with the plurality of first guide grooves 115, so that the inner bottle 12 can be slidably disassembled from the tubular shell 11. Figure 6

[0045] It can be understood that, since the plurality of first guide strips 125 are matched with the plurality of first guide grooves 115, the number of the first guide grooves 115 and the first guide strips 125 is equal, and the distribution interval of the first guide grooves 115 and the first guide strips 125 is also the same. For example, as shown in Figure 5 and Figure 6 three first guide grooves 115 and three first guide strips 125 are exemplarily provided.

[0046] In the present application, there are various combinations between different numbers of first guide strips 125 and different cross-sectional shapes of the tubular shell 11. When the cross-sectional shape of the tubular shell 11 is a polygon, the first guide strips 125 can be distributed at the center positions of the multiple sides of the polygon. When the cross-sectional shape of the tubular shell 11 is a circle, the first guide strips 125 can be distributed on the circle at uniform angles. The uniform distribution in the present application means that there is a certain distribution rule (such as central symmetry, axial symmetry, radial symmetry, etc.), so that the first guide strips 125 are uniformly spread on the inner wall of the tubular shell 11 in the view from above.

[0047] By increasing the guide strips and the guide grooves, the torsional resistance of the tubular shell 11 and the inner bottle 12 can be increased, and the possibility of the tubular shell 11 and the inner bottle 12 being separated, relatively rotating and deformed due to the torsional force can be reduced. At the same time, the first guide strips 125 also play the role of the ribs, which can further increase the compressive resistance of the tubular shell 11.

[0048] As shown in Figure 7 and Figure 8 the emulsion packaging bottle 1 can further include a threaded middle ring 15, which includes a through hole 151 and an inner thread 152. The bottle mouth 121 is provided with an outer thread 1211, which is matched with the inner thread 152. The threaded middle ring 15 is assembled on the bottle mouth 121. The diameter of the through hole 151 is smaller than the diameter of the pump head 13. The threaded middle ring 15 is used to fix the pump head 13 at the bottle mouth 121, and the through hole 151 is used to pass through the liquid outlet 132.

[0049] ​By setting the threaded middle ring 15, and the through hole 151 of the threaded middle ring 15 does not affect the liquid outlet 132, so it can reinforce the assembly of the inner bottle 12 and the pump head 13.

[0050] In order to further reduce the use of materials, on the basis of any of the above embodiments, in an embodiment, as shown in the front view, Figure 9 The tubular shell 11 can be a hollow structure.

[0051] Further, the outer wall of the tubular shell can be provided with anti-skid lines to further improve the grip feel.

[0052] By making a hollow structure, the use of materials for the tubular shell 11 is further reduced, thus reducing the input of raw materials. At the same time, the hollow pattern can increase the friction between the palm and the outer wall of the tubular shell 11 when in use, thereby playing a role in preventing slipping and improving the use experience. The emulsion packaging product with anti-skid structure is more secure to hold in hand.

[0053] It can be understood that the pattern of the hollow structure adopted in the present application is not specifically required, and those skilled in the art can select according to the scheme content provided by the present application and actual production needs. For example, the hollow structure is made into a pattern that meets the ergonomic grip, and for example, the hollow structure is made into a brand promotion content.

[0054] Further, as shown in the right view, Figure 10 The tubular shell 11 in the present application can be partially hollow, and the outer wall of the part that is not hollow (i.e. the part shown as "maximum silk printing range" in Figure 10 The outer wall of the part that is not hollow can be pasted with a sticker. The sticker can print product-related information, and the sticker can also be made of anti-slip and easy-to-clean materials.

[0055] In a packaging bottle with a shell, the shell usually blocks the fingers to some extent, and when in use, one hand needs to be lifted, and the other hand needs to avoid the shell from above to press the packaging bottle.

[0056] For this, in an embodiment of the present application, as shown, Figure 11 The first end 111 is provided with an opening 116, the upper end of the opening 116 is open, and the depth of the opening 116 is not less than the pressing depth of the pressure head 14.

[0057] Through the above scheme, the tubular shell 11 in the present application is provided with an opening 116 at the first end 111. Since the upper end of the opening 116 is open, when pressing, the fingers do not need to be perpendicular to the top to press the pressure head 14, and the fingers can pass through the opening 116 to press the pressure head 14, so the remaining fingers can be used to hold the tubular shell 11, thus it can be used with one hand, improving the ease of use of the emulsion packaging bottle 1.

[0058] In the present application, as shown in Figure 11 and Figure 12 The inner wall of the tubular shell 11 is provided with a plurality of second guide strips 117 extending from the leading end 111 to the trailing end 112, and the length of the second guide strips 117 is greater than the pressing depth of the pressing head 14. The side surface of the pressing head 14 is provided with a plurality of second guide grooves 142, and the plurality of second guide grooves 142 are matched with the plurality of second guide strips 117 one by one, so that the pressing head 14 can slide in the tubular shell 11.

[0059] Through the above scheme, the pressing head 14 in the present application can move up and down at a specified position and will not rotate in the tubular shell 11, so as to reduce the possibility of the pressing head 14 coming out after assembly. At the same time, since the pressing head 14 will not rotate in the tubular shell 11, the liquid outlet position of the emulsion packaging bottle 1 is relatively fixed, so it will not be squeezed out to different positions, reducing the probability of the emulsion being squeezed out to the assembly gap, so that the emulsion packaging bottle 1 is easier to keep clean.

[0060] Further, the upper end of the second guide groove 142 can be closed, so that when the pressing head 14 is pressed, the second guide strip 117 will not protrude from the pressing head 14 by passing through the second guide groove 142, reducing the possibility of the second guide strip 117 injuring the user and improving the safety of use.

[0061] In summary, the emulsion packaging bottle 1 provided by the embodiment of the present application can generate a downward force on the fitted inner bottle 12 through the tubular shell 11 which gradually increases from the leading end 111 to the trailing end 112, and at the same time, through the cooperation of the annular groove 113 and the first annular protrusion 124 of the trailing end 112, an upward force can be generated. The directions of the two forces are opposite, so that the inner bottle 12 is firmly assembled in the tubular shell 11. Since the tubular shell 11 does not have a bottom, the overall mass is reduced, achieving the purpose of reducing the use of materials. The reduction in mass also means an improvement in user experience, which can solve the technical problems proposed in the present application.

[0062] Further, the present application also provides various further embodiments, which further optimize the structure and improve the user experience.

[0063] The above description is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, which should be considered as the protection scope of the present application.
