Technical Field

[0001] The utility model relates to the field of beauty and skin care packaging, and particularly relates to a double-chamber bottle. Background Art

[0002] With the increasing development of the beauty and skin care industry, some products need to mix two liquids or mix a liquid with a powder during use. Therefore, this type of product needs to be packaged in a double-chamber bottle with two storage chambers.

[0003] Currently, most double-chamber bottles on the market are provided with a diaphragm on the bottle body to divide the bottle body into two storage chambers, and then a puncturing member is provided. When in use, the diaphragm is punctured so that the products in the two storage chambers can be mixed. As Figure 1 shown, it is a conventional puncturing member on the market currently. One end of the puncturing member is made into an inclined surface, but the contact area between the inclined surface and the diaphragm is relatively large, and the resistance received when puncturing the diaphragm is relatively large, which is not convenient for puncturing the diaphragm and cannot be operated with one hand.

[0004] In view of this, the inventor of this case conducted in-depth research on the above problems, and thus this case was born. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a double-chamber bottle that is convenient for puncturing a diaphragm.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A double-chamber bottle includes a bottle body. The bottom of the bottle body has an open end, a partition member is connected to the open end, a puncturing member is connected to the partition member, a diaphragm is connected to the end face of the partition member away from the puncturing member, a limiting member for restricting the puncturing member from moving towards the partition member is provided between the partition member and the puncturing member. The puncturing member includes a cover body and a cylinder connected inside the cover body. A puncturing portion and a guiding surface are integrally formed at one end of the cylinder away from the cover body. The puncturing portion is in the shape of a triangular pyramid, the puncturing portion and the guiding surface are oppositely arranged, the distance between the puncturing portion and the cover body is greater than the distance between the guiding surface and the cover body, a blade portion is provided between the puncturing portion and the guiding surface, and the distance between the blade portion and the cover body gradually decreases from the end close to the puncturing portion to the end away from the puncturing portion.

[0008] Preferably, the distance between the guiding surface and the cover body gradually increases from the end close to the outer side of the cylinder to the end away from the outer side of the cylinder.

[0009] Preferably, a snap ring is provided on the inner wall of the partition member, and a resilient snap position matching the snap ring is provided on the outer wall of the cylinder. The puncturing member is connected to the partition member through the cooperation of the resilient snap position and the snap ring.

[0010] Preferably, the compartment member includes a first circular ring, a second circular ring, and a third circular ring integrally formed in sequence. The diaphragm is connected to one end of the first circular ring away from the second circular ring. The outer diameters of the first circular ring and the third circular ring are smaller than the outer diameter of the second circular ring, and the outer diameter of the second circular ring is equal to the outer diameter of the bottle body. A connecting groove is provided between the first circular ring and the second circular ring, and a convex ring is provided on the inner wall of the bottle body.

[0028] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] In this embodiment, the direction when the double-compartment bottle is placed on the horizontal plane is used as the reference direction for the up-down direction.

[0030] As Figure 2-6 shown, a double-compartment bottle includes a bottle body 10. The bottom of the bottle body has an open end, and a compartment piece 20 is connected to the open end. A piercing piece 30 is connected to the compartment piece 20. A diaphragm 40 is connected to the end surface of the compartment piece 20 away from the piercing piece 30. A limiting piece 50 for restricting the piercing piece 30 from moving towards the compartment piece 20 is provided between the compartment piece 20 and the piercing piece 30.

[0031] In this embodiment, the bottle body 10 has a cavity, the cavity is communicated with the open end, and a breakable sealing part 11 is connected to the upper part of the bottle body 10.

[0032] In this embodiment, the thickness of the diaphragm 40 is less than or equal to 0.08 mm.

[0033] The piercing member 30 includes a cover body 31 and a cylinder 32 connected inside the cover body 31. At one end of the cylinder 32 away from the cover body 31, a piercing portion 321 and a guiding surface 322 are integrally formed. The piercing portion 321 is in the shape of a triangular pyramid. The piercing portion 321 and the guiding surface 322 are arranged opposite to each other. The distance between the piercing portion 321 and the cover body 31 is greater than the distance between the guiding surface 322 and the cover body 31. There is a blade portion 323 between the piercing portion 321 and the guiding surface 322. The distance between the blade portion 323 and the cover body 31 gradually decreases from the end close to the piercing portion 321 to the end away from the piercing portion 321. In this embodiment, the blade portion 323 is also integrally formed on the cylinder 32, and the piercing portion 321, the guiding surface 322 and the blade portion 323 are directly integrally formed. In this embodiment, the blade portion 322 is arc-shaped.

[0034] In this embodiment, the outer diameter of the cylinder 32 matches the inner diameter of the compartment member 20. After the piercing portion 321 pierces the diaphragm 40, the cylinder 32 communicates with the cavity of the bottle body 10.

[0035] As a preferred mode of this embodiment, the distance between the guiding surface 322 and the cover body 31 gradually increases from the end close to the outer side of the cylinder 32 to the end away from the outer side of the cylinder 32. By providing the guiding surface 322, after the piercing portion 321 pierces the diaphragm 40, the position of the diaphragm 40 corresponding to the guiding surface 322 does not contact the cylinder 32, so that the position of the diaphragm 40 corresponding to the guiding surface 322 can be connected to the compartment member 20, avoiding the diaphragm 40 completely detaching from the compartment member 20 and affecting the subsequent use of the compartment bottle.

[0036] As a preferred mode of this embodiment, a snap ring 21 is provided on the inner wall of the compartment member 20, and a resilient snap position 324 matching the snap ring 21 is provided on the outer wall of the cylinder 32. The piercing member 30 is connected to the compartment member 20 through the cooperation of the resilient snap position 324 and the snap ring 21. In this embodiment, the resilient snap position 324 is a protrusion provided on the outer wall of the cylinder 32. Through the tight fit or interference fit of the snap ring 21 and the resilient snap position 324, it effectively prevents the piercing member 30 from falling off the compartment member 20 during transportation or when the compartment bottle expands and contracts due to temperature changes.

[0037] As a preferred mode of this embodiment, the compartment member 20 includes a first ring 22, a second ring 23 and a third ring 24 integrally formed in sequence from top to bottom. The diaphragm 40 is connected to one end of the first ring 22 away from the second ring 23. The outer diameters of the first ring 22 and the third ring 24 are smaller than the outer diameter of the second ring 23. The outer diameter of the second ring 23 is equal to the outer diameter of the bottle body 10. A connecting groove 25 is provided between the first ring 22 and the second ring 23. A convex ring 12 is provided on the inner wall of the bottle body 10. The compartment member 20 is connected to the bottle body 10 by the convex ring 12 being snap-fitted into the connecting groove 25.

[0038] The first ring 22 has a connecting portion near the diaphragm 40, and the outer diameter of the connecting portion is smaller than the outer diameter of the first ring 22, so as to reduce the resistance of the bin member 20 entering the bottle body 10 and facilitate installation.

[0039] In this embodiment, the limiting member 50 is connected to the end face of the second ring 23 away from the first ring 22 through a connecting piece or a plurality of connecting strips. A tearing notch 51 is provided on the limiting member 50 to facilitate tearing the limiting member 50 from the bin member 20.

[0040] The using method of this bin bottle: Remove the limiting member 50, and then push the piercing member 30 towards the bin member 20 so that the piercing member 30 pierces the diaphragm 40, making the cavity of the bottle body 10 communicate with the cylinder 32, so that the contents in the cavity are mixed with the contents in the cylinder 32.

[0041] According to the experiment, the pushing force required for the piercing member shown as follows Figure 1 to pierce the diaphragm is 60N·mm - 80N·mm, while the pushing force required for the piercing member 30 provided in this embodiment to pierce the diaphragm 40 is ≤30N·mm. By changing the shape of the piercing portion 321, the piercing portion 321 can more easily pierce the diaphragm 40, which is convenient for use.

[0042] In summary, when the piercing portion 321 pierces the diaphragm 40, continue to push the piercing member 30 towards the bin member 20, and the blade portion 323 cuts or pushes away the diaphragm 40 from the bin member 20. When the piercing member 30 is completely pushed in, the position of the diaphragm 40 corresponding to the outlet surface 322 is still connected to the bin member 20, preventing the diaphragm 40 from completely detaching from the bin member 20 and affecting the subsequent mixing and use of the double-bin bottle; by setting the tight fit or interference fit between the snap ring 21 and the rebound retaining position 324, the piercing member 30 is effectively prevented from detaching from the bin member 20.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
