Description

Novel double-agent bottle structure

Technical Field

The present invention relates to liquid containers, and more particularly to a novel dual-dose bottle structure.

Background

The multi-element liquid packaging bottle is a novel packaging structure, has wide application prospect, and can be used in the fields of medicines, cosmetics or washing products and the like. For various functional liquids with stable chemical properties after mixing, it is common at present to mix solutions in factories and then assemble the solutions into an independent container, and users directly use the mixed chemical products. For the mixed liquid with unstable chemical properties and multiple functions, in order to ensure the chemical properties of various liquids to be stable, the liquids with different chemical properties are respectively and independently packaged, and when the liquid is used, the liquids are respectively poured out and mixed, so that the mixed liquid is prevented from undergoing chemical reaction in the process of storage, and the efficacy of the product is reduced.

The prior multi-element liquid packaging bottle has various forms, and the simplest structure is that a cavity is arranged at the outlet of the packaging bottle, when the packaging bottle is used by a user, liquid with different functionalities is extruded out firstly, and the liquid is used after being pre-mixed in the cavity, for example, the mixed liquid is used for cleaning clothes and the like. Along with the increasing demands of users, when the liquid is used in a small range such as local stains, only a small amount of liquid is needed to be mixed, even two drops or three drops are needed, at this time, if a pre-mixing mode is adopted, the mixed liquid is too small in quantity, and the situation that the mixed liquid cannot be poured or extruded exists, the mixing dosage is needed to be increased, and waste is caused; in addition, the double-agent bottle package is characterized in that the design of the liquid outlet nozzle is unreasonable, the liquid can not be completely mixed after flowing out, and the use effect of the liquid can not reach the due effect.

Disclosure of Invention

Accordingly, the present invention is directed to solve the above-mentioned problems, and provides a novel dual-dose bottle structure, which can achieve the purpose of automatically and fully mixing the liquids in different cavities after flowing out of the dual-dose bottle without pre-mixing.

The technical scheme adopted by the invention is that the novel double-agent bottle structure comprises two single-agent bottles respectively positioned at the left side and the right side, wherein the two single-agent bottles are respectively provided with a bottle opening, and the novel double-agent bottle structure also comprises a conversion base arranged on the two bottle openings and a liquid outlet arranged on the conversion base;

the conversion base includes: two third liquid outlet pipes with a delta L interval; the two third liquid outlet pipes are communicated with the two bottle openings and distributed in a staggered manner;

the liquid outlet nozzle comprises: two fourth liquid outlet pipes which are closely combined and distributed left and right in an eight shape are separated by a baffle plate; the lower ends of the two fourth liquid outlet pipes are respectively communicated with the two third liquid outlet pipes in a one-to-one correspondence manner.

The distance between two bottle openings of the existing double-agent bottle is large, and after the double-agent bottle is directly extruded, two liquids are difficult to meet together in a short distance, so that the double-agent bottle is inconvenient for users to use. The double-agent bottle structure is a bilateral symmetry structure, and the axial center lines of the two third liquid outlet pipes are positioned between the axial center lines of the two bottle openings and are all in the same vertical plane; the pipe diameter of the third liquid outlet pipe is not larger than the diameter of the bottle mouth, so that two third liquid outlet pipes are communicated with two bottle mouths in one-to-one correspondence and distributed in a staggered mode, the space at the communicated position is a vertical overlapping space between the third liquid outlet pipe and the bottle mouth, and the cross section of the space is smaller than that of the third liquid outlet pipe or the bottle mouth.

In the left side structure of the double-agent bottle structure, liquid flowing out of the bottle mouth of the left single-agent bottle enters the third liquid outlet pipe from the overlapped space between the third liquid outlet pipe and the bottle mouth, so that the flow entering the third liquid outlet pipe is forced to be reduced; subsequently, the liquid flows out from the third liquid outlet pipe into a fourth liquid outlet pipe communicated with the third liquid outlet pipe. Similarly, in the right structure of the double-agent bottle structure, the liquid flowing out from the bottle mouth of the right single-agent bottle flows out after sequentially passing through the third liquid outlet pipe and the fourth liquid outlet pipe on the right side. The two fourth liquid outlet pipes are closely combined, and a common partition board is formed in the middle of the two fourth liquid outlet pipes, so that the two fourth liquid outlet pipes are an integral body without gaps; and the two fourth liquid outlet pipes are distributed left and right in an eight shape, so that the liquid finally flowing out of the two fourth liquid outlet pipes is gradually gathered and is scattered on an object after crossing at the point P. In the process, as the final outflow outlet of the two liquids is closest, the minimum distance between the P point and the upper surface of the fourth liquid outlet pipe is ensured, and a user can obtain a better liquid mixing effect without adjusting the double-agent bottle to a specific angle during use.

In this technical scheme, through setting up the switching base that is used for changing the liquid flow direction and deriving the liquid outlet mouth of liquid for liquid in two single-dose bottles is extruded the back from the bottleneck, gets into the liquid outlet mouth after changing the liquid flow direction, flows through the liquid outlet mouth, meets in the P point in the short distance. The third liquid outlet pipe and the bottle mouth are distributed in a staggered mode, so that the liquid flow flowing into the fourth liquid outlet pipe is controlled, and liquid is prevented from flowing out. When the liquid is used for dripping in a small range, a user does not need to squeeze even, the double-agent bottle is obliquely placed, the liquid flows out from the fourth liquid outlet pipe under the action of self gravity, and only two to three drops of liquid can be intersected at the mouth, so that waste or inconvenience in use caused by liquid pre-mixing is avoided. When the novel bottle body is used for large-scale application, a user extrudes the bottle body with great force, the liquid flows out of the fourth liquid outlet pipe and has a certain initial speed, and two liquid flows are divergently sprayed to the surface of an object after being converged along the extended line of the axis of the fourth liquid outlet pipe which is distributed in the shape of the Chinese character 'ba', so that large-area application is realized.

Further, two single-agent bottles are formed by extrusion blowing respectively through the same die, each single-agent bottle is formed by a bottom surface, a top surface and a surrounding wall to form a containing cavity, the surrounding wall comprises an attaching wall, a convex edge and a groove are formed in the attaching wall, and when the attaching walls of two single-agent bottles are relatively attached, the convex edge on one single-agent bottle is embedded into the groove on the other single-agent bottle, so that the two single-agent bottles are combined into a double-agent bottle container.

The two single-dose bottles are formed by extrusion blowing through the same die, so that the two single-dose bottles can be guaranteed to be identical in tolerance range, namely, the wall thickness is identical, the shape is identical, and the same deformation is generated when the two single-dose bottles are subjected to the same force. Further, the surrounding wall also comprises an extrusion wall and two holding walls respectively used for connecting the extrusion wall and the adhesion wall; the extrusion wall is a curved surface with the middle part protruding outwards, and the holding wall is a curved surface with the middle part recessed inwards. When the two are attached, a user holds the double-agent bottle by one hand, the palm tiger mouth is positioned in the middle concave part of the left or right holding part, the thumb is positioned at the outer convex part of the middle part of the extrusion wall of one single-agent bottle, the other four fingers are positioned at the outer convex part of the middle part of the extrusion wall of the other single-agent bottle, and then, the two single-agent bottles are extruded by applying force by one hand, so that the two single-agent bottles generate the same deformation, the liquid level of the residual liquid in the double-agent bottles is kept consistent, the user can use the two liquids at the same time, waste is avoided, and the equal liquid is mixed, so that the superposition effect of the two liquids is enhanced.

In order to fix the two single-dose bottles together, the single-dose bottle body is arranged symmetrically relative to the central line of the bottle mouth, namely, the two holding walls are symmetrical relative to the central line of the bottle mouth; secondly, the convex rib and the groove can be formed by bending the attaching wall during extrusion blowing, and the convex rib can also be a solid body; the convex edges are tightly matched with the grooves, the joint walls of the two single-agent bottles are close to each other in opposite directions to form mirror symmetry, in the process of the close of the two joint walls, the convex edge of one single-agent bottle is clamped into the groove of the other single-agent bottle, and similarly, the convex edge of the other single-agent bottle is clamped into the groove of the one single-agent bottle to form two groups of jogged structures, so that the two single-agent bottles are fixed together to form the double-agent bottle container. In order to improve the fixing effect of the two single-agent bottles and avoid the release of the two single-agent bottles in the use process, adhesive can be smeared in the convex edges or the grooves, and the two single-agent bottles are completely fixed through the adhesive after being embedded. Furthermore, the two single-dose bottles after being attached are coated with the fastening pieces, such as the shrink film, so that the packaging machine is suitable for irregular shape packages with curvature change, has the functions of dust prevention and touch-proof theft replacement, can be used for printing product information on the shrink film for propaganda, and integrates fixation and packaging.

Further, the convex ribs and the grooves are symmetrically distributed on the outer surface of the attaching wall relative to the axial center line of the bottle mouth.

The convex edges and the grooves are continuously provided with at least 1 group or intermittently provided with at least 2 groups along the height direction of the attaching wall; the convex edges are parallel to the grooves and are suitable for the rectangular-like attaching wall; or the V-shaped distribution is formed between the convex edges and the grooves, and the V-shaped distribution is suitable for the upper and lower narrow attaching walls.

For two single-dose bottles with larger concave curvature of the holding wall, the upper part and the lower part of the single-dose bottle are wider, the middle part of the single-dose bottle is narrower, the convex edges and the grooves can be distributed along the diagonal line of the bonding wall, so that the convex edges and the convex grooves are distributed in an X shape, the single-dose bottle is used for being embedded on one hand, and the convex edges and the grooves also serve as reinforcing ribs on the other hand, so that the single-dose bottle surrounding wall structure is reinforced.

Further, the conversion base further comprises a first liquid outlet pipe and a second liquid outlet pipe;

the lower part of the first liquid outlet pipe is of an inward-folded petal-shaped structure and is in interference fit with the bottle mouth;

the second liquid outlet pipe is an inclined pipeline, the lower end of the second liquid outlet pipe is communicated with the first liquid outlet pipe, and the upper end of the second liquid outlet pipe is communicated with the third liquid outlet pipe.

In actual production, the axes of two bottlenecks are parallel to each other, and the second drain pipe can't directly insert in the bottleneck, at this moment, through setting up first drain pipe, makes it insert in the bottleneck, and rethread its second pipeline of intercommunication slope reaches sealed butt joint's effect. When the conversion base is produced, the petal-shaped structure is convenient for demoulding; when the first liquid outlet pipe is in butt joint with the bottle mouth, the inward petal shape plays a role of guiding, so that the lower part of the first liquid outlet pipe is ensured to be smoothly plugged into the bottle mouth; in addition, the petal-shaped structure slits facilitate demolding during production of the conversion base.

Secondly, when the distance between two bottlenecks is great, dislocation range is great between bottleneck or first drain pipe and the third drain pipe, when leading to overlapping cross-section between the two less, in order to guarantee that liquid gets into the third drain pipe smoothly, also in the accessible second drain pipe passes through liquid transition to the third drain pipe for follow-up play liquid.

Furthermore, in order to ensure the close fit between the first liquid outlet pipe and the bottle mouth, a clamping part is arranged on the bottle mouth, the clamping part is of an annular structure, the vertical section of the clamping part is a transverse right trapezoid, and the inclined edge of the clamping part faces upwards; the periphery of the first liquid outlet pipe is provided with a columnar buckling part, the cross section of the columnar buckling part is elliptical, and 2 windows are arranged on the columnar cylindrical surface. The major axis of the ellipse is larger than the outer diameter of the clamping part of the bottle mouth, and the minor axis is smaller than the outer diameter of the clamping part of the bottle mouth. When the bottle is assembled, the buckling part presses the bottle mouth, the oval ring buckling part is deformed into a round shape and then returns to an oval shape, and the buckling position is formed at the position of the short axis of the oval shape and is tightly buckled with the bottle mouth clamping part.

Further, the two single-agent bottles are integrally formed and are of a non-detachable structure. Specifically, each single-dose bottle is formed by a bottom surface, a top surface and a surrounding wall to form a containing cavity, a convex bottle opening is arranged on the top surface, a clamping part is arranged on the bottle opening, the clamping part is of an annular structure, the vertical section of the clamping part is of a transverse right trapezoid, and the inclined side of the clamping part faces upwards. The surrounding wall comprises a planar attaching wall, an extrusion wall and two holding walls respectively used for connecting the extrusion wall and the attaching wall; the extrusion wall is a curved surface with the middle part protruding outwards, and the holding wall is a curved surface with the middle part recessed inwards. Secondly, the two attaching walls of the two single-agent bottles are connected through connecting ribs, the connecting ribs are distributed at the center position of the attaching wall along the height direction of the attaching wall, and the distance between the two single-agent bottles is controlled by controlling the thickness of the connecting ribs, so that the containing cavities of the two single-agent bottles are mutually independent and keep a certain distance; meanwhile, a certain distance is kept between the two bottle openings, and a necessary space is provided for waste generated by extrusion blowing by a gap between the two bottle openings during extrusion blowing molding. Meanwhile, in order to make the liquid junction P after flowing out from the fourth liquid outlet pipe shorter from the end of the fourth liquid outlet pipe, the distance between the two bottle openings needs to be reduced, that is, the distance between the outer edge of the bottle opening and the attaching wall is reduced, so that the distance b4=1 to 10mm, preferably b4=4 mm, 5mm, 6mm, 8mm and 10mm between the outer edge of the bottle opening and the attaching wall is set.

Further, the conversion base also comprises a rotating opening arranged at the upper part of the first liquid outlet pipe; the two third liquid outlet pipes are positioned in the rotary opening, and a residual liquid cavity is formed between the rotary opening and the two third liquid outlet pipes.

When the liquid is extruded, a user stands the double-agent bottle up and places, particularly when a large amount of liquid is mixed, a small amount of mixed liquid sometimes remains on the liquid outlet nozzle, the part of liquid can flow downwards under the action of gravity, and the liquid is temporarily stored by arranging the rotary ports around the two third liquid outlet pipes, and enclosing a residual liquid cavity together with the outer walls of the third liquid outlet pipes and the inclined pipe walls of the second liquid outlet pipes, so that the pollution of the double-agent bottle body or the pollution of the hands of the user is avoided. Furthermore, the conversion base is integrally formed, so that liquid leakage caused by gaps among the first channel, the second channel and the third channel is avoided.

Further, the liquid outlet nozzle further comprises a sleeve pipe which is communicated with the fourth liquid outlet pipe and sleeved on the third liquid outlet pipe, and a supporting plate for supporting the sleeve pipe; the support plate is matched with the rotary opening.

Because the conversion base and the liquid outlet nozzle are of a detachable structure, in order to improve the tightness of the joint of the third liquid outlet pipe and the fourth liquid outlet pipe, a sleeve is sleeved on the outer wall of each of the two third liquid outlet pipes, and the bottom of each sleeve can be vertically and downwards extended to be obtained by the fourth liquid outlet pipe. And moreover, the liquid outlet nozzle is fixed on the conversion base through interference fit of the sleeve and the third liquid outlet pipe.

In this technical scheme, can adopt integrated into one piece's mode to mould plastics two fourth drain pipes, the inclined plane of eccentric round platform enclosing wall can be used as the guide surface of liquid, and the upright one side of two fourth drain pipes is public face, i.e. baffle, and two fourth drain pipes pass through backup pad joint on the mouth of revolveing.

Further, the double-agent bottle structure further comprises a spiral cover which is arranged on the two fourth liquid outlet pipes and used for sealing, a clamping groove is formed in the spiral cover, and an elastic body component used for sealing the fourth liquid outlet pipes is arranged in the clamping groove.

The spiral cover wraps the spiral opening and the liquid outlet nozzle and is in threaded connection with the outer wall of the spiral opening. The traditional sealing modes are divided into end face sealing or inner plug sealing; with this structure, the inner plug seal affects the junction effect of the two liquids, and therefore, an end face seal is employed. Specifically: the clamping groove in the spiral cover is arranged to be of an annular structure, the vertical section of the clamping groove is L-shaped, the elastic body member is fixed in an L-shaped folded angle, and when the spiral cover and the spiral opening are screwed tightly through threads, the elastic body member is tightly pressed with the upper end face of the fourth liquid outlet pipe, so that the purpose of sealing the fourth liquid outlet pipe is achieved.

As can be seen from fig. 3 and fig. 4, the single-dose bottle 1 is formed by a bottom surface, a top surface 12 and a surrounding wall 13, a protruding bottle mouth 11 is provided on the top surface 12, a clamping portion 111 is provided on the bottle mouth 11, the clamping portion 111 is in a ring-shaped structure, the vertical section of the clamping portion is a transverse right trapezoid, and the inclined edge of the clamping portion faces upwards. As shown in fig. 2, the enclosing wall 13 includes a planar attaching wall 131, and further includes a pressing wall 132 and two holding walls 133 for respectively connecting the pressing wall and the attaching wall; the squeezing wall 132 is a curved surface with a convex middle part, and the holding wall 133 is a curved surface with a concave middle part.

The attaching wall 131 is provided with a convex edge 141 and a concave groove 142, when the attaching walls 131 of the two single-dose bottles are attached relatively, the convex edge 141 on one single-dose bottle is embedded into the concave groove 142 on the other single-dose bottle, so that the two single-dose bottles are combined into a container for containing two different liquids.

The minimum width B3 of the setting B1 and the fitting wall 131 satisfies: 0.3.ltoreq.B1/B2.ltoreq.0.8, preferably B1/B3=0.3 or 0.4 or 0.5 or 0.6 or 0.7 or 0.8.

As shown in fig. 5 and fig. 6, the conversion base 2 is integrally formed and has a bilateral symmetry structure, and includes a bottle mouth 11, a first liquid outlet pipe 21, a second liquid outlet pipe 22 and a third liquid outlet pipe 23 which are sequentially communicated, and a minimum distance Δl=1-3 mm between the outer walls of the two third liquid outlet pipes 23, so that a distance between the two third liquid outlet pipes 23 is minimum.

The lower parts of the two first liquid outlet pipes 21 are of inward-folded petal-shaped structures, so that the two first liquid outlet pipes 21 are ensured to be smoothly plugged into the two bottle mouths, and the first channels 41 through which two liquids flow are formed. The axial center lines of the two third liquid outlet pipes 23 are positioned between the axial center lines of the two bottle mouths 11 and are all in the same vertical plane; the pipe diameter of the third liquid outlet pipe 23 is not larger than the diameter of the bottle mouth 11, so that two third liquid outlet pipes 23 are communicated with two bottle mouths 11 in one-to-one correspondence and are distributed in a staggered mode, the space at the communicated position is a vertical overlapping space between the third liquid outlet pipe 23 and the bottle mouth 11, and the cross section of the space is smaller than that of the third liquid outlet pipe 23 or the bottle mouth 11.

The outer wall of the screw opening 24 is provided with threads for screwing with the screw cap 5.

Because the cross section of the first liquid outlet pipe 21 is larger, large liquid burst is easy to occur during extrusion, and the use of small-range liquid dripping cannot be realized, an included angle a2=30-45 degrees, preferably a2=30 degrees or 35 degrees or 40 degrees or 45 degrees, between the inclined pipe wall of the second liquid outlet pipe 22 and the horizontal plane is set, so that liquid burst is conveniently restrained; in addition, the smaller included angle a2 can also reduce the height of the second liquid outlet pipe 22, thereby reducing the overall height of the conversion base 2; the larger included angle a2 makes the second liquid outlet pipe 22 have a longer inclined surface, so that the foam generated by the liquid can be prevented.

Since the fourth liquid outlet pipe 32 is an eccentric truncated cone enclosure wall structure, in order to obtain a suitable length ratio of the liquid outlet nozzle, an included angle a1=45° to 65 ° between the side surface of the fourth liquid outlet pipe 32 and the horizontal plane is set, and preferably a1=45° or 50 ° or 55 ° or 60 ° or 65 °.

As can be seen from fig. 11, the upper surface of the support plate 31 is provided with a residual liquid inlet 35 communicating with the residual liquid chamber 25, and a small amount of mixed liquid remaining on the liquid outlet flows along the outer wall of the fourth liquid outlet pipe 32 to the circular surface, and then enters the residual liquid chamber 25 through the residual liquid inlet 35 on the support plate 31. In order to avoid reverse outflow of the residual liquid from the residual liquid inlet 35 when the user pours the double-dose bottle next time, the relationship between the minimum distance L1 between the edge of the residual liquid inlet 35 and the edge of the supporting part 31 and the radius L2 of the supporting part 31 is set to be as follows: preferably, L1/l2=0.4 to 0.6, and L1/l2=0.4 or 0.5 or 0.6, i.e. the circular surface of the support portion 31, which is not opened, is ensured to be as large as possible, so as to prevent the residual liquid from flowing out.

As shown in fig. 5 and 6, the screw cap 5 covers the screw opening 24 and the liquid outlet 3, and is in threaded connection with the outer wall of the screw opening 24; next, an elastomer material or a composite material is embedded in the inner surface of the top of the screw cap 5, and the elastomer material or the composite material is tightly attached to the outlet of the fourth liquid outlet pipe 32 in the closed state.

As shown in fig. 14, a clamping groove 51 is provided in the screw cap 5, and the clamping groove 51 is provided with an elastomer member 52 for sealing the fourth liquid outlet pipe; the clamping groove 51 is provided with an annular structure, the vertical section of the clamping groove is L-shaped, the elastic body member 52 is fixed in an L-shaped folded angle, and after the spiral cover 5 and the spiral opening 24 are screwed tightly through threads, the elastic body member 52 is tightly pressed with the upper end face of the fourth liquid outlet pipe 32, so that the purpose of sealing the fourth liquid outlet pipe 32 is achieved.

In the double-agent bottle structure in this embodiment, two groups of channels are symmetrically distributed left and right, taking a left side channel as an example, when a user squeezes the double-agent bottle body, liquid enters the first liquid outlet pipe 21 from the bottle mouth 11, foam generated in the liquid flowing process is accumulated on the left shoulder part of the first liquid outlet pipe 21, the liquid enters the third liquid outlet pipe 23 from the inclined second liquid outlet pipe 22, dead angles of the inner walls of the channels are reduced, so that the foam contained in the liquid finally entering the fourth liquid outlet pipe 32 from the third liquid outlet pipe 23 is less or no foam contained, and then the liquid smoothly flows out from the outlet of the fourth liquid outlet pipe 32; similarly, the fourth outlet pipe 32 of the right-hand channel in fig. 12 also discharges a liquid with little or no foam. After the two liquids in the double-agent bottle flow out along the extension line of the axis of the fourth liquid outlet pipe 32, the two liquids meet at the intersection point P of the extension lines and then are sprinkled on the object. Because the outlet diameter of the fourth liquid outlet pipe 32 is smaller, when the bottle body is only needed to be gently extruded when the bottle body is used in a small range, two to three drops of liquid flow out from the outlet of the fourth liquid outlet pipe 32, and because the included angle a1 between the side surface of the fourth liquid outlet pipe 32 and the horizontal plane is larger, the distance between the intersection point P and the upper end surface of the fourth liquid outlet pipe 32 is shorter, and the two to three drops of liquid can be smoothly mixed, so that a user can use the double-agent bottle at a position closer to an object when the bottle is used. When the large-scale use is performed, the bottle body is extruded under high force, the liquid flowing out from the outlet of the fourth liquid outlet pipe 32 has a certain speed, the two liquids still meet along the intersection point P of the extension line, and then, under the action of the initial speed, the mixed liquid is dispersed, and the area of the mixed liquid falling to an object is large, so that the large-scale use is realized.

Because the conversion base 2 and the liquid outlet nozzle 3 are of an integrated structure, no gap exists among the first liquid outlet pipe 21, the second liquid outlet pipe 22 and the third liquid outlet pipe 23, and no gap exists between the sleeve 34 and the fourth liquid outlet pipe 32. When the conversion base 2 and the liquid outlet nozzle 3 are successfully installed, the sleeve 34 is tightly sleeved with the third liquid outlet pipe 23, so that liquid leakage can be avoided. When the user uses the dual-dose bottle and then vertically places the dual-dose bottle, a little liquid remains at the outlet of the fourth liquid outlet pipe 32, and the liquid cannot flow into the dual-dose bottle under the action of liquid tension due to the fact that the outlet of the fourth liquid outlet pipe 32 is smaller, but slides down along the inclined plane of the fourth liquid outlet pipe 32, and enters the residual liquid cavity 25 from the residual liquid inlet 35, the liquid in the residual liquid cavity cannot flow into the dual-dose bottle or flow out of the cavity, and therefore liquid pollution to the liquid in the dual-dose bottle or pollution to the bottle body is avoided.

Example 2

The difference between this embodiment and embodiment 1 is that the two single-dose bottles 1 in the novel dual-dose bottle structure are integrally formed, and the fastening piece 15 for fixing the two single-dose bottles can be omitted by adopting the integrally formed structure, so that the overall dual-dose bottle structure is simpler and more compact. The single-dose bottle 1 is characterized in that a containing cavity is formed by a bottom surface, a top surface 12 and a surrounding wall 13, a convex bottle opening 11 is arranged on the top surface 12, a clamping part 111 is arranged on the bottle opening 11, the clamping part 111 is of an annular structure, the vertical section of the clamping part is of a transverse right trapezoid, and the inclined side of the clamping part is upward. As shown in fig. 2, the enclosing wall 13 includes a planar attaching wall 131, and further includes a pressing wall 132 and two holding walls 133 for respectively connecting the pressing wall and the attaching wall; the squeezing wall 132 is a curved surface with a convex middle part, and the holding wall 133 is a curved surface with a concave middle part.

As shown in fig. 15, the two attaching walls 131 of the two single-dose bottles 1 are connected by a connecting rib 143, the connecting rib 143 is distributed at the center position of the attaching wall 131 along the height direction of the attaching wall 131, and the space between the two single-dose bottles 1 is controlled by controlling the thickness of the connecting rib 143, so that the accommodating cavities of the two single-dose bottles 1 are mutually independent and keep a certain distance; at the same time, a certain distance is maintained between the two bottle mouths 11.

Considering the requirement of the integrally formed double-agent bottle during extrusion blowing, necessary space is provided for waste generated by extrusion blowing, and meanwhile, the distance between the outer edge of the bottle mouth 11 and the attaching wall is required to be reduced as small as possible, so that the distance between the two bottle mouths 11 is reduced, and therefore, with reference to fig. 4, the distance b4=1-10 mm between the outer edge of the bottle mouth 11 and the attaching wall 131 is set, preferably, b4=4 mm, 5mm, 6mm, 8mm and 10mm.

It is apparent that the present invention is disclosed in the above embodiments, but is not limited thereto. Any person skilled in the art may make variations and modifications to the above description without departing from the spirit and scope of the invention. The scope of the invention should, therefore, be determined with reference to the appended claims.
