A bottle structure for holding liquids Technical Field

[0001] This utility model relates to the field of bottles, and in particular to a bottle structure for holding liquids. Background Technology

[0002] In traditional glue bottles, the glue is typically placed directly inside the bottle and then squeezed out by external pressure, as shown in patent CN222699079U. However, this method of directly squeezing the bottle has many inconveniences, such as discomfort to the hand and potential deformation, affecting the bottle's ability to stand upright. Therefore, a bottle structure that facilitates easy squeezing and is resistant to external deformation is needed. Summary of the Invention

Detailed Implementation

[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0034] Example 1:

[0035] As shown in Figures 1-8, a liquid-containing bottle structure includes a bottle body 1 and a cap 2, wherein the bottle body 1 and the cap 2 are detachably connected. The bottle body 1 includes an inner cavity 11 and an outer shell 12. The inner cavity 11 is nested within the hollow outer shell 12. The sidewalls of the inner cavity 11 are made of a flexible material with deformability. The outer shell 12 has a hollow cavity inside for housing the inner cavity 11. The bottom and top of the outer shell 12 are respectively provided with openings. The bottom opening of the outer shell 12 is for inserting the inner cavity 11, and the top opening of the outer shell 12 is for extending out of the inner cavity 11. The portion of the inner cavity 11 extending out of the outer shell 12 is connected to the cap 2. The shell 12 has cuts 13 on both sides that penetrate the exterior of the shell 12 and the cavity. The cuts 13 extend vertically downward to the lower edge of the shell 12. With the action of the cuts 13, the shell 12 on both sides can be squeezed relatively easily without being uncomfortable to the touch. In addition, after squeezing the shell 12, the soft inner cavity 11 inside will deform, thereby squeezing out the liquid stored in the inner cavity 11. Furthermore, the material of the shell 12 is harder than that of the inner cavity 11 and is not easily deformed. It is mainly with the help of the cuts 13 that a certain degree of squeezing action can be completed. Therefore, the shape of the shell 12 can quickly recover after squeezing and maintain a stable shape.

[0036] The inner side of the outer shell 12 is also provided with a rib structure 14 for guiding and supporting the positioning of the inner cavity 11; the rib structure 14 protrudes from the inner wall of the outer shell 12 and abuts against the outer side of the inner cavity 11; the rib structure 14 is rounded at one end near the bottom of the outer shell 12, and the rounded end is close to the inner cavity 11, so that the inner cavity 11 can be inserted into the interior of the outer shell 12 from the lower opening of the outer shell 12; in this example, four rib structures 14 are provided on the inner side of the outer shell 12, and the rib structures 14 extend downward in the vertical direction on the inner side of the outer shell 12.

[0037] The outer periphery of the top of the inner cavity 11 is provided with a snap-fit ​​protrusion 15 that engages with the top of the outer shell 12; after the inner cavity 11 is inserted into the outer shell 12, the snap-fit ​​protrusion 15 protrudes from the top of the outer shell 12 and engages with the top of the outer shell 12 to prevent the inner cavity 11 from falling out of the outer shell 12.

[0038] A protruding limiting block 16 is also provided on the outer side of the inner cavity 11, and a limiting groove 17 corresponding to the limiting block 16 is provided on the inner wall of the outer shell 12 to restrict the rotation of the inner cavity 11 within the outer shell 12; a protruding contact block 18 is provided in the limiting groove 17, and the contact block 18 and the limiting block 16 form a snap-fit ​​engagement to further prevent the inner cavity 11 from detaching from the outer shell 12; in this example, the contact block 18 protrudes from the limiting groove 17 and contacts the outer side of the inner cavity 11, and the contact block 18 is located in the middle position inside the outer shell 12; when the outer shell 12 is squeezed, the protruding design of the contact block 18 achieves a better squeezing effect.

[0039] The cover 2 includes an upper cover 21 and a lower cover 22, wherein the upper cover 21 and the lower cover 22 are connected by threads, and the lower cover 22 is connected to the inner cavity 11 by threads; the end of the lower cover 22 near the upper cover 21 is set as a pointed tip, so that the bottle 1 structure in this example has two different sizes of liquid outlet diameter.

[0040] The outer side of the upper cover 21 is provided with a return indicator arrow 23, which makes it easy to indicate the tightness of the cover 2 and prevent the stored liquid from deteriorating because the cover 2 is not tightened.

[0041] The outer shell 12 and the inner cavity 11 have corresponding shapes; the overall shape of the inner cavity 11 is a flat bottle 1, wherein the cuts 13 on the outer shell 12 are located on both sides of the flat inner cavity 11, corresponding to the narrower side, which facilitates compression.

[0042] During implementation, by setting an outer shell 12 with a notch 13 and a flexible inner cavity 11, it is convenient to squeeze the inner cavity 11 through the outer shell 12 to squeeze out the stored liquid, avoiding discomfort to the hands, while maintaining the shape stability of the outer shell 12; by setting a rib structure 14 inside the outer shell 12, the position of the inner cavity 11 inside the outer shell 12 is restricted; by setting a snap-fit ​​protrusion 15 on the top of the inner cavity 11, it forms a snap-fit ​​with the outer shell 12, preventing the two from easily separating; by setting a limiting block 16 in conjunction with a limiting groove 17 and a contact block 18, the positions of the outer shell 12 and the inner cavity 11 are fixed on the one hand, and a better squeezing effect is achieved on the inner cavity 11 on the other hand.

[0043] Example 2:

[0044] As shown in Figures 9-11, the technical solution of this embodiment is an improvement based on Embodiment 1. An outwardly protruding insert block 19 is provided on the outer side of the top of the inner cavity, and a recessed insert groove 110 corresponding to the insert block 19 is provided on the inner side of the top of the outer shell. In this example, the insert blocks 19 are symmetrically arranged on both sides of the top of the inner cavity. When the inner cavity is connected to the outer shell, the insert block 19 is inserted into the insert groove 110 from bottom to top, facilitating alignment between the inner cavity and the outer shell. The top of the insert block 19 is set as an arc surface to facilitate access to the insert groove 110. Correspondingly, the snap-fit ​​protrusion 15 on the top of the inner cavity is removed.

[0045] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
