Description

TECHNICAL FIELD

[0001] The utility model relates to a conical spike easy-to-open bottle cap assembly. BACKGROUND

[0002] The utility model discloses a subpackaging type beverage bottle cap assembly discloses a utility model patent application file no. "CN222311402U" including bottle cap, main container, connecting piece, work baffle etc. The main container one end is connected with bottle cap, and the other end is connected with the bottle body of beverage bottle, and the connecting piece is arranged between bottle cap and main container, and the connecting piece is equipped with sharp part near one end of sealing membrane, and the lower end of sharp part is equipped as bevel, and the upper end of bevel is connected with horizontal section, and the main container is equipped with sealing membrane at the bottom of containing cavity. When first twist and open bottle cap, the work baffle on bottle cap will drive connecting piece to move, and the bevel on connecting piece will pierce sealing membrane, and makes solute and solvent contact and mix. In the process of shaking beverage bottle.

[0003] The bottle cap assembly has the following defects:

[0004] Firstly, "sharp part is designed as bevel", according to the specification attached to the disclosure file Figure 2 The structure can be clearly seen. When rotating the bottle cap, the bevel actually "rotary cuts" the sealing membrane. Since the geometry of the bevel, the force direction is not completely perpendicular to the surface of the sealing membrane when it pierces the sealing membrane. Specifically, part of the force of the bevel is converted into the force required for circular sliding on the end surface of the sealing membrane, and the other part is converted into the force required for piercing the sealing membrane vertically. In actual use, a larger force needs to be applied by hand to open the bottle cap assembly.

[0005] Secondly, the piercing force is unevenly distributed during the rotary cutting of the bevel, the opening size and shape are not easy to accurately control, and the sealing membrane cannot be completely opened, which easily leads to insufficient mixing of solute and solvent, affecting the mixing efficiency.

[0006] Finally, the bottle cap and the connecting piece are linked through the work baffle, which not only has a complex structure, but also increases the cost of the bottle cap assembly. Utility model content

[0007] The utility model solves the technical problem of the prior art by providing a conical spike easy-to-open bottle cap assembly. By setting a sharp body in the form of a cone at the end of the piercing member, and distributing the sharp end of the sharp body on the central axis of the piercing body, the bottle cap assembly can be easily opened and mixed with beverages.

[0008] In order to achieve the above object, the utility model provides the following technical scheme: the bottle cap subassembly of easy opening of cone prick, including bottle cap and the main container of bottle cap screw connection, the main container is equipped with containing chamber in, and the bottom of containing chamber is equipped with sealing membrane, the containing chamber is equipped with the pricking piece, the pricking piece is connected with bottle cap screw, the main container is equipped with the sliding guide structure between pricking piece, when bottle cap rotates, the pricking piece moves along the axis direction of main container under the action of sliding guide structure, its characterized in that: the end of pricking piece towards sealing membrane is equipped with the sharp body of cone, and the tip of sharp body is distributed on the central axis of pricking body.

[0009] Adopt the above technical scheme, the tip of conical sharp body is located on the central axis of pricking piece, when bottle cap rotates, pricking piece will only move along the axis direction of main container and will not rotate under the action of sliding guide structure. Because the geometry of conical sharp body, when pricking sealing membrane, the direction of force is almost completely perpendicular to the surface of sealing membrane, so that the force required for pricking is more concentrated, reduces the dispersion of force, so that opening bottle cap is more labor-saving, and the user does not need to exert more force in the process of use can easily prick the sealing membrane.

[0010] The above-mentioned cone-prick easy-to-open bottle cap assembly can be further provided with: the sealing membrane is covered with a thin-walled structure, and the thickness of the thin-walled structure is less than the thickness of the sealing membrane.

[0011] Adopt the above technical scheme, it should be noted that the thickness of the sealing membrane here refers to the thickness of the sealing membrane excluding the thin-walled structure. By providing a thin-walled structure with a thin wall on the sealing membrane, when the conical sharp body pricks the sealing membrane, the thin-walled structure can guide the sharp body to easily pierce the sealing membrane, further improving the convenience of opening the bottle cap and saving more labor. At the same time, the size and shape of the opening are more controllable.

[0012] The above-mentioned cone-prick easy-to-open bottle cap assembly can be further provided with: the thin-walled structure includes a pricking positioning surface arranged at the middle of the sealing membrane and corresponding to the tip of the sharp body, an annular thin-walled ring is arranged around the outer periphery of the pricking positioning surface, a plurality of groups of strip-shaped thin-walled lines are connected to the annular thin-walled ring, a group of thickening blocks is arranged between each adjacent two groups of strip-shaped thin-walled lines, the thickness of the thickening blocks is consistent with the thickness of the pricking positioning surface, and the thickness of the thin-walled lines and the thickness of the thin-walled ring are both less than the thickness of the thickening blocks.

[0013] Using the above technical solution, the piercing positioning surface cooperates with the annular thin-walled ring, allowing the conical sharp object to accurately pierce the center of the sealing film, reducing the force required for piercing. Several sets of strip-shaped thin-walled lines surround the outer periphery of the annular thin-walled ring and diverge radially. Their thinness guides the conical sharp object to expand the opening along a predetermined path during piercing, resulting in a more uniform opening expansion. This avoids the problem of insufficient mixing of solute and solvent due to irregular openings, improving mixing efficiency. Meanwhile, the thickened block provides support to the sealing film when not pierced, stably separating the substance to be mixed from the contents of the bottle.

[0014] The aforementioned cone-shaped easy-open bottle cap assembly can be further configured as follows: the sliding guide structure includes several groups of guide blocks that surround the outer periphery of the puncture member and are spaced apart from each other; the inner circumferential surface of the main container is provided with a set of strip-shaped guide grooves corresponding to each group of guide blocks; one side of the guide block is provided with a first abutting surface; the strip-shaped guide groove is provided with a second abutting surface on one side corresponding to the first abutting surface; the other side of the guide block is provided with a first inclined surface; and the other side of the strip-shaped guide groove is provided with a second inclined surface.

[0015] Using the above technical solution, the guide block and the strip guide groove cooperate with each other. When the bottle cap rotates, the piercing component moves smoothly along the axis of the main container under the guidance of the guide block and the strip guide groove. The guide block and the strip guide groove are respectively provided with a first abutment surface and a second abutment surface on one side, which limit and guide the piercing component circumferentially during its movement. This also facilitates the assembly of the piercing component with the main container. Because the end of the piercing component is threaded to the bottle cap, and the size of the bottle cap is larger than the size of the piercing component, it is difficult for the guide block and the strip guide groove to align perfectly in one go when inserting the piercing component into the main container by holding the bottle cap. However, by slowly rotating the bottle cap in the direction of tightening, the first and second inclined surfaces cooperate, and the guide block slides into the strip guide groove in this direction. After assembly, when the bottle cap is rotated in the direction of opening, the first and second abutment surfaces cooperate, realizing the axial movement of the piercing component.

[0016] The aforementioned cone-shaped easy-open bottle cap assembly can be further configured such that: the piercing component also includes a connecting column connected to the sharp body, the outer periphery of the connecting column is evenly distributed with a first thread structure that is threaded to the bottle cap, and several sets of guide blocks are distributed between the connecting column and the sharp body.

[0017] Using the above technical solution, when the bottle cap is turned, the internal thread of the bottle cap interacts with the first thread structure on the connecting column, and in conjunction with the sliding guide structure, drives the puncture component to move along the axial direction of the main container.

[0018] The aforementioned cone-shaped easy-open bottle cap assembly can be further configured such that: the interior of the piercing body is hollow, and the outer periphery of the sharp body is provided with a number of flow holes communicating with the interior of the piercing body.

[0019] By adopting the technical scheme, after the sealing film is pierced by the piercing body, the substance in the main container flows into the bottle through the flow-through hole along the inside of the piercing body, and the mixing is completed.

[0020] The conical piercing easy-to-open bottle cap assembly can be further provided as follows: the main container comprises a first connecting pipe body threadedly connected with the bottle cap and a second connecting pipe body away from the bottle cap, the second connecting pipe body comprises a sealing film connecting pipe body and a connecting flange ring sleeved on the outer periphery of the sealing film connecting pipe body, an installation gap is formed between the connecting flange ring and the sealing film connecting pipe body, the inner periphery of the connecting flange ring is provided with a second screw thread structure threadedly connected with the bottle mouth, and the inner periphery of the connecting flange ring is further provided with a plurality of groups of anti-theft bevel gears uniformly arranged.

[0021] By adopting the technical scheme, the first connecting pipe body is used for threadedly connecting with the bottle cap. The sealing film connecting pipe body is used for not only storing the substance but also processing the sealing film at the bottom. The installation gap between the connecting flange ring and the sealing film connecting pipe body is used for “inserting the bottle mouth and threadedly connecting with the second screw thread structure”. The anti-theft bevel gears are further provided, which have a certain anti-theft function and can avoid opening the main container by a stranger. Meanwhile, the main container will not be loosened after being installed, and the sealing performance is good.

[0022] The conical piercing easy-to-open bottle cap assembly can be further provided as follows: the outer peripheries of the bottle cap and the main container are provided with anti-skid lines.

[0023] By adopting the technical scheme, the bottle cap and the main container are convenient to hold or twist by hands.

[0024] The utility model will be further described in detail in combination with the drawings and embodiments. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 3 The illustrated cone-shaped easy-open bottle cap assembly includes a bottle cap 1 and a main container 2 threadedly connected to the bottle cap 1. The main container 2 has a receiving cavity with a sealing membrane 3 at its bottom. A piercing element 4 is located within the receiving cavity and is threadedly connected to the bottle cap 1. A sliding guide structure is provided between the main container 2 and the piercing element 4. When the bottle cap 1 rotates, the piercing element 4 moves along the axis of the main container 2 under the action of the sliding guide structure. The end of the piercing element 4 facing the sealing membrane 3 has a cone-shaped sharp body 9, the tips of which are distributed along the central axis of the piercing body. The tips of the cone-shaped sharp bodies 9 are located on the central axis of the piercing element 4. When the bottle cap 1 rotates, the piercing element 4 only moves along the axis of the main container 2 under the action of the sliding guide structure and does not rotate. Due to the geometry of the conical sharp object 9, when it pierces the sealing film 3, the direction of the force is almost completely perpendicular to the surface of the sealing film 3, which makes the force required for piercing more concentrated and reduces the dispersion of force, making it easier to open the bottle cap 1. Users can easily pierce the sealing film 3 without applying a lot of force during use.

[0031] The sealing membrane 3 is covered with a thin-walled textured structure. This structure includes a piercing positioning surface 5 located in the center of the sealing membrane 3, corresponding to the tip of the sharp object 9. An annular thin-walled ring 6 surrounds the outer periphery of the piercing positioning surface 5. Several sets of strip-shaped thin-walled lines 7 are connected to the annular thin-walled ring 6. A thickening block 8 is positioned between each pair of adjacent sets of strip-shaped thin-walled lines 7. The thickness of the thickening block 8 is the same as that of the piercing positioning surface 5, and the thickness of both the thin-walled lines and the thin-walled ring is less than the thickness of the thickening block 8. The piercing positioning surface 5 and the annular thin-walled ring 6 work together to allow the conical sharp object 9 to accurately pierce the center of the sealing membrane 3, reducing the force required for piercing. The several sets of strip-shaped thin-walled lines 7, surrounding the outer periphery of the annular thin-walled ring 6 and radiating radially, are relatively thin and guide the conical sharp object 9 to expand the opening along a predetermined path during piercing, resulting in a more uniform opening expansion. This avoids the problem of insufficient mixing of solute and solvent due to irregular openings, improving mixing efficiency. The thickened block 8 provides support to the sealing film 3 without being punctured, thus stably separating the substance to be mixed from the substance inside the bottle.

[0032] The sliding guide structure comprises several groups of guide blocks 10 arranged around the outer periphery of the piercing member 4 and spaced apart from each other, and the inner periphery of the main container 2 is provided with a group of strip-shaped guide grooves 19 corresponding to each group of guide blocks 10. One side of the guide block 10 is provided with a first abutting surface 11, and one side of the strip-shaped guide groove 19 is provided with a second abutting surface 12 corresponding to the first abutting surface 11. The other side of the guide block 10 is provided with a first inclined surface 13, and the other side of the strip-shaped guide groove 19 is provided with a second inclined surface 14. The guide block 10 and the strip-shaped guide groove 19 are matched with each other, and when the bottle cap 1 rotates, the piercing member 4 moves smoothly along the axis direction of the main container 2 under the guidance of the guide block 10 and the strip-shaped guide groove 19. One side of the guide block 10 and the strip-shaped guide groove 19 is respectively provided with the first abutting surface 11 and the second abutting surface 12, which limits and guides the piercing member 4 in the circumferential direction during the movement of the piercing member 4. Then, the assembly between the piercing member 4 and the main container 2 is facilitated. Since the end of the piercing member 4 is threadedly connected with the bottle cap 1, the size of the bottle cap 1 is larger than that of the piercing member 4, so during the process of inserting the piercing member 4 into the main container 2 by holding the bottle cap 1, the guide block 10 and the strip-shaped guide groove 19 are difficult to be matched in place at one time, and the bottle cap 1 is slowly rotated in the direction of screwing the bottle cap 1. The first inclined surface 13 and the second inclined surface 14 are matched with each other, and the guide block 10 slides into the strip-shaped guide groove 19 in this direction. After the assembly is completed, when the bottle cap 1 is rotated in the direction of opening the bottle cap 1, the first abutting surface 11 and the second abutting surface 12 are matched to realize the axial movement of the piercing member 4.

[0033] The piercing member 4 further comprises a connecting column 15 connected with the sharp body 9, the outer periphery of the connecting column 15 is uniformly distributed with a first threaded structure 16 threadedly connected with the bottle cap 1, and several groups of guide blocks 10 are distributed between the connecting column 15 and the sharp body 9. When the bottle cap 1 is screwed, the internal thread of the bottle cap 1 interacts with the first threaded structure 16 on the connecting column 15, and cooperates with the sliding guide structure to drive the piercing member 4 to move along the axis direction of the main container 2.

[0034] The piercing body is internally hollow, and the outer periphery of the sharp body 9 is provided with several groups of flow-through holes 17 in communication with the inside of the piercing body. After the piercing body pierces the sealing film 3, the substances in the main container 2 flow into the bottle through the inside of the piercing body and the flow-through holes 17, and the mixing is completed.

[0035] The main container 2 comprises a first connecting pipe body 2a which is threadedly connected with the bottle cap 1, a second connecting pipe body which is away from the bottle cap 1, the second connecting pipe body comprising a sealing film connecting pipe body 2b, a connecting flange ring 2c which is sleeved on the outer periphery of the sealing film connecting pipe body 2b, and an installation gap existing between the connecting flange ring 2c and the sealing film connecting pipe body 2b, an inner peripheral surface of the connecting flange ring 2c being provided with a second thread structure 2d which is threadedly connected with the bottle mouth, and the inner peripheral surface of the connecting flange ring 2c being further provided with a plurality of groups of anti-theft inclined teeth 2e which are uniformly arranged. The first connecting pipe body 2a is used for threadedly connecting with the bottle cap 1. The sealing film connecting pipe body 2b is not only used for storing substances but also used for processing a sealing film 3 at the bottom. The installation gap between the connecting flange ring 2c and the sealing film connecting pipe body 2b is used for “inserting the bottle mouth and threadedly connecting with the second thread structure 2d”. The anti-theft inclined teeth 2e are further provided, have a certain anti-theft function, can avoid a stranger from opening the main container 2, and simultaneously the main container 2 will not be loosened after being installed and has good sealing performance.

[0036] The outer peripheries of the bottle cap 1 and the main container 2 are both provided with anti-skid lines 18. This is convenient for a person to hold or twist the bottle cap 1 and the main container 2.

[0037] The specific operation method of the embodiment is as follows:

[0038] The main container 2 is installed on the bottle mouth through the second thread structure 2d, and under the action of the anti-theft inclined teeth 2e, the stable connection with the bottle mouth is maintained, and simultaneously the anti-theft property is had. The piercing member 4 is threadedly connected with the bottle cap 1 through the first thread structure 16, and simultaneously the guide block 10 on the outer periphery of the piercing member 4 cooperates with the strip-shaped guide slot 19 in the main container 2. The bottle cap 1 and the main container 2 are also threadedly connected (this is the common knowledge in the art and has been embodied in the prior art). When the bottle cap 1 is twisted, the piercing member 4 moves along the axial direction of the main container 2 until the sealing film 3 is pierced. When the piercing member 4 is separated from the bottle cap 1, that is, the two are not threadedly connected, the bottle cap 1 can be opened by continuously twisting the bottle cap 1. Compared with the existing bottle cap 1 assembly, the embodiment is more labor-saving.
