Definitions
- the present invention refers to a thermoplastic bottle of the type comprising a main body, which is essentially prismatic and moulded in a single-piece, a bottom part or base, and a mouth, as well as a method for the manufacture and filling of same.
- the invention refers to groupings of the previous bottles and to the methods of obtaining such groupings.
- thermoplastic bottle embodiments which consist of a main body which is essentially prismatic and moulded in a single-piece, a bottom part or base and a mouth.
- these bottles are manufactured conventionally by means of blow moulding methods of a preform formed from extruded grains of a thermoplastic material, conforming the main body of the bottle into a single-piece, with its mouth open by which the bottle is filled in its right-hand position and once the same has been conformed, with the product to be contained therein.
- the mouth is covered with a cap or complex laminate metalized plastic top, which is joined to the annular edge of the mouth by adhesive or, alternatively, with a screw-on-cap, possibly provided with a hermetic protective seal.
- thermoforming technique which up to the present time, is unknown in the field of the manufacturing technique of bottles of this type.
- the object of the present invention is a new bottle of thermoplastic material, of the type mentioned, which essentially is characterized in that it comprises a hermetically sealing portion for the mouth, moulded together with the bottle body forming with the latter a single-piece, said sealing portion being delimited by a weakening of the material which constitutes the bottle, adjacent to the periphery of the mouth and the bottom part or base being constituted by a sheet of thermoplastic material integrally joined by thermowelding to the lower part of the bottle body walls, after the bottle has been filled with the product to be contained therein, all of it adapted so that upon exerting a pulling or pushing force on the sealing portion which is greater than a minimum predetermined effort, the weakening is liable to breaking, either completely or partly, in order to separate the mouth sealing portion, with the aim of achieving the opening of the mouth.
- the top is stuck by its inner face to the outer face of the sealing portion by an adhesive or glue, in such a way that, on unscrewing the top, the breaking of the annular weakening takes place.
- the bottle comprises a cap constituted by a laminate material, joined to the outer face of the sealing portion by an adhesive or glue, in such a way that on pulling the cap manually the complete or partial breaking of the weakening takes place.
- the weakening has an open arch shape and the cap comprises a pulling and retention tab, in such a way that, once the bottle has been opened by breaking the weakening, the bottle can be closed again by reversion of the opening movement of the closing part so that the cap covers the formed mouth.
- the present invention also has as an object a grouping of bottles of thermoplastic material, which is essentially characterized in that it comprises a plurality of bottles joined without interruption by their bottom part or base by easily-broken joining straps, made of the constituent thermoplastic material itself of the bottom part of the bottles.
- Another object of the present invention is a grouping of bottles of thermoplastic material, which in essence, is characterized in that by comprising a plurality of bottles and a linkage body of the same, the linkage body being constituted by straps of plastic material and at least one handle part, which links the straps to one another in a continuous manner on which multiple orifices of diameter similar to that of the bottle neck are made, provided with notches radially extending on their periphery, providing the edges of the orifices with a certain flexibility, all in such a way that the bottles can be inserted by pressure in the orifices, remaining held by the effect of the tightening of the edges of the orifices on the bottles' necks.
- the present invention also has as an object, a method of novel concept and function, applicable for the manufacture and filling of bottles and groups of bottles according to that defined in the preceding paragraphs, characterized essentially in that, starting from a sheet of thermoplastic material, it comprises the stages of:
- thermoplastic material [0016] heating the sheet to a temperature greater than that of the thermofluence of the thermoplastic material
- the method comprises the intermediate stages of applying glue or adhesive between the inner face of the screw-on-cap and the outer face of the sealing portion of the bottle mouth and of subsequently applying the cap to the mouth.
- the stage of applying glue or adhesive and of applying the screw-on-cap can be done simultaneous to the stage of conforming the body of the bottle, for which the cap itself constitutes the bottom part of the negative mould, the threading of the cap forming the surface moulding of the outer threading of the bottle.
- the stage of applying glue and applying the screw-on-cap is done immediately after stage of forming the weakening.
- the method comprises the intermediate stage of applying, by sticking, a top to the outer face of the closing part.
- the method comprises, after the thermowelding stage, the stage of separating by cutting each conformed bottle, filled and closed, from the rest of the sheets of the material which constitute the body and the bottom part of the bottles, respectively.
- the former comprises the additional stage of forming the grouping, by means of cutting of the sheets of the material that constitute the body and bottom part of the bottles, respectively.
- the method of the present invention allows for the manufacture by thermoforming and the filling and final closing of the bottles, in a totally continuous process, which consequently can give rise to modular machines and not so long as the current ones, guaranteeing asepsis in the operations and providing greatly reduced operating costs.

- the bottles 1 , 10 of thermoplastic material which are disclosed comprise a main body 2 and essentially prismatic moulded single-piece, a bottom part or base 5 and a mouth 3 .
- the bottles 1 , 10 comprise a hermetically sealing portion 6 of the mouth 3 , which in the closed and full position of the bottle, as it comes out of the factory, is moulded into a single-piece together with the body 2 of the bottle 1 , 10 .
- a hermetically sealing portion 6 of the mouth 3 which in the closed and full position of the bottle, as it comes out of the factory, is moulded into a single-piece together with the body 2 of the bottle 1 , 10 .
- FIG. 14 an example of bottle 1 has been represented, whose sealing portion 6 has been partly broken.
- the aforementioned sealing portion 6 is delimited, as can be clearly seen in the details of FIGS. 3, 4, 6 and 7 , by a weakening 7 of the thermoplastic material which constitutes the bottle, made adjacent to the periphery of the mouth 3 .
- the weakening 7 is preferably circumference-shaped, although it can also adopt the shape of other, different curves. In addition, the weakening 7 can be open or closed curve-shaped.
- the bottom part or base 5 of the bottle 1 , 10 is formed by a sheet of thermoplastic material, which preferably is the same as that of the rest of the bottle 1 , 10 , or, in other words, that of the body 2 and the sealing portion 6 .
- the bottom part 5 is integral to the lower part of the walls of the body 2 of the bottle 1 , 10 by thermowelding, after the bottle has been filled with the product it is supposed to contain.
- FIGS. 1 to 4 and 12 to 14 the embodiments of the bottle provided for closing by means of a screw-on-cap 8 , are represented, of which particular illustrative examples are shown in FIGS. 1 to 4 and 12 to 14 .
- the closing by means of the screw-on-cap 6 works with a complementary outer threading 9 with which the neck 4 of the bottle 1 is fitted.
- the top 8 is stuck by its inner face to the outer face of the sealing portion 6 by means of an adhesive or glue 11 .
- the bottles 1 of the invention can be closed by means of a cap 12 constituted by a sheet material, preferentially of a complex of inert and metalized plastic, which is joined to the outer face of the sealing portion 6 by like means of an adhesive or glue 11 .
- the embodiments of the bottles equipped with the cap 12 are represented by means of numerical reference 10 , and specific examples of them are shown in FIGS. 5 to 11 and 15 .
- the bottle 1 , 10 can come from the factory, filled and closed and ready for the consumption of its content, in the hermetically sealed position exemplified in FIGS. 2, 3, 5 , 9 , 11 and 13 .
- the breaking of the weakening 7 for the opening of the mouth 3 is done by manually pulling the top 12 .
- the top 12 is preferably equipped with a pulling tab 13 or a pulling and retention tab 35 , which facilitates the operation.
- FIGS. 7 and 10 both details are displayed showing the result of this pulling operation.
- FIGS. 8 to 11 embodiment examples of the bottle 10 equipped with top 12 are shown, in which the weakening 7 is in open arc-shape at the ends of which a hinge is determined at the sealing portion 6 .
- the tab of the top 12 adopts the form of a pulling and retention tab 35 , so that, once the bottle 10 is open by breaking of the weakening 7 , the former can be closed again, again lowering the sealing portion 6 against the mouth 3 and covering with the top 12 the upper part of the bottle adjoining the mouth 3 .
- the neck 4 of the bottle 10 comprises at its part adjacent to the mouth 3 , a split 40 or a similar formation, adapted for housing part of the pulling and retention tab 35 when the latter is tightened manually against the split 40 .
- the optional and non-essential feature concurs that, in extension of the neck 4 , the bottles 1 , 10 comprise a neck 36 which facilitates the exit of the bottle's content.
- the bottle 10 is of the type that are closed by means of a top 12 equipped with a pulling and retention tab 35
- the bottle 1 is of those intended for closing by means of a screw-on-cap 8 .
- FIG. 16 a group of bottles 1 , 10 is shown which are joined in twos at their base through straps 15 , which link in a continuous manner with the constituent material of the bottom part or base 5 of the bottles 1 , 10 , giving rise to a grouping 14 of bottles.
- Each of the bottles 1 , 10 in this case, six, of the grouping 14 , can be separated from the rest by means of breaking the straps 15 , for which the width of the strap 15 is small enough to facilitate its breaking.
- FIG. 17 another alternative form of the grouping 37 of a plurality of bottles 1 , 10 , is shown, in this case six, too, in accordance with the invention.
- the bottles 1 , 10 are removably joined by means of a linkage body 24 , constituted by two straps 38 of plastic material and a handle part 26 , in this example in arched shape or in “half cannon”, which link in a continuous manner to the straps 38 .
- the straps 38 holes 39 are made, one for each bottle 1 , 10 , of similar diameters, although somewhat smaller than that of a minimum diameter part 41 of the bottle 1 , 10 in the adjacent area to the neck 4 (see FIGS. 1 to 9 ).
- These minimum diameter parts 41 can be constituted by a hollow made in the body 2 or neck 4 of the bottle, or even at the lower edge of a screw-on-cap 8 , such as in the case illustrated in FIG. 17.
- each orifice 39 is provided with four notches 25 extending radially, which provides the orifice edge with a certain flexibility or spring effect.
- the bottles 1 , 10 are inserted through their neck 4 , under pressure in the orifices 39 , the notches 25 facilitating the insertion and remaining held by the effect of the tightening of the edges of the orifices 39 on the minimum diameter part 41 of the bottles 1 , 10 .
- FIGS. 18 to 26 show different stages of the method, peculiar to the invention, of the filling and closing of the bottles 1 , 10 and formation of the groupings 14 , 37 .
- Said method consists of the treatment of a sheet 16 of thermoplastic material, by means of the sequential phases which are shown below:
- thermoplastic material [0074] heating the sheet 16 to a temperature greater than that of the thermofluence of the thermoplastic material
- the punch 19 has the shape adapted to the desired conformation of the weakening 7 : if this is annular, the punch 19 will be annular, whereas if it is open-arched, the punch will consequently be open-arched.
- thermowelding a sheet of thermoplastic material to the periphery of the aforementioned upper opening 20 , the bottom part or base 5 remaining determined and, therefore, the bottle 1 , 10 finished and hermetically sealed (FIGS. 24, 25 and 26 ).
- FIG. 18 shows the stage in which the thermoplastic material is applied against the inner wall of the negative mould 18 , under pressure or pneumatic vacuum.
- the method comprises the stage of applying glue or adhesive 11 between the inner face of the screw-on-cap 8 and the outer face of the sealing portion 6 of the mouth 3 of the bottle 1 and of subsequently applying the cap 8 to the mouth 3 .
- the applying of glue or adhesive 11 and of the cap 8 can be done simultaneous to the phase of conforming the body 2 of the bottle 1 (FIG. 23).
- the mould 18 is divided in two halves 33 and 34 , of which a lower movable half 34 receives, in a separated position from the upper half 33 and into a slot 42 for which purpose it is equipped, to the cap 8 , after which it is situated in continuity with the upper half 33 , in such a way that cap 8 itself constitutes the bottom part of the whole of the negative mould 18 .
- the threading of the top 8 then goes on to constitute the surface mould for the outer threading 9 of the bottle 1 .
- the stage of applying glue 11 and applying the top 8 is carried out immediately after the stage of forming the weakening 7 .
- the method comprises the intermediate stage of applying by sticking, the top 12 , to the outer face of the sealing portion 6 .
- This stage of application of the top 12 can be simultaneous to the blowing or aspiration stage.
- FIG. 19 shows that cap 12 is formed by cutting by means of a clipping 46 from a sheet 47 of a suitable material and next going on to constitute the bottom part of the negative mould 18 of the bottle 10 .
- FIG. 25 shows the mode of forming the bottle groupings 14 of FIG. 16.
- the die-cutter 44 has the right configuration to separate a cutting from the sheets 16 and 21 in such a way that the bottles, of which there are six in the case illustrated, are linked by straps 15 which are joined to the bottom parts 5 of the bottles 1 , 10 .
- FIG. 26 shows the conformation of the linkage body 24 for the formation of the bottle groupings 37 of FIG. 17.

Description
- The present invention refers to a thermoplastic bottle of the type comprising a main body, which is essentially prismatic and moulded in a single-piece, a bottom part or base, and a mouth, as well as a method for the manufacture and filling of same. Likewise, the invention refers to groupings of the previous bottles and to the methods of obtaining such groupings.
- At the present time, for the contention of food products, in particular dairy products such as milk, drinkable yogurts, fruit juices or similar, a multiplicity of thermoplastic bottle embodiments are known, which consist of a main body which is essentially prismatic and moulded in a single-piece, a bottom part or base and a mouth.
- Nowadays, these bottles are manufactured conventionally by means of blow moulding methods of a preform formed from extruded grains of a thermoplastic material, conforming the main body of the bottle into a single-piece, with its mouth open by which the bottle is filled in its right-hand position and once the same has been conformed, with the product to be contained therein. Following this operation, the mouth is covered with a cap or complex laminate metalized plastic top, which is joined to the annular edge of the mouth by adhesive or, alternatively, with a screw-on-cap, possibly provided with a hermetic protective seal.
- In practice, many known bottles of this type present an imperfect airtightness, dripping frequently being found around the joining areas between the cap and the mouth.
- Moreover, at present the production of the full and closed definitive container is done according to a discontinuous batch production process, which consists of the extrusion, heating, blow moulding, filling and closing stages. These stages are carried out at different facilities which can be located in remote places, or even in very far-off production plants. The transportation of the bottles from one facility or location to another requires very strict hygienic measures to be adopted, which do not always guarantee the total asepsis of the materials and of the products and which are very costly, raising problems of a logistical nature.
- In order to solve the drawbacks and problems mentioned, the inventors have thought of a new continuous method for this type of bottle, giving rise to bottles of novel concept and design and which entail, in the same way, other additional advantages.
- Basically, the novel procedure is based on the application of the thermoforming technique, which up to the present time, is unknown in the field of the manufacturing technique of bottles of this type.
- The object of the present invention is a new bottle of thermoplastic material, of the type mentioned, which essentially is characterized in that it comprises a hermetically sealing portion for the mouth, moulded together with the bottle body forming with the latter a single-piece, said sealing portion being delimited by a weakening of the material which constitutes the bottle, adjacent to the periphery of the mouth and the bottom part or base being constituted by a sheet of thermoplastic material integrally joined by thermowelding to the lower part of the bottle body walls, after the bottle has been filled with the product to be contained therein, all of it adapted so that upon exerting a pulling or pushing force on the sealing portion which is greater than a minimum predetermined effort, the weakening is liable to breaking, either completely or partly, in order to separate the mouth sealing portion, with the aim of achieving the opening of the mouth.
- According to the invention, in the case of the bottles that incorporate a screw-on-cap, which collaborates with a complementary external threading which the bottle neck is fitted with, the top is stuck by its inner face to the outer face of the sealing portion by an adhesive or glue, in such a way that, on unscrewing the top, the breaking of the annular weakening takes place.
- Alternatively, in accordance with the invention, the bottle comprises a cap constituted by a laminate material, joined to the outer face of the sealing portion by an adhesive or glue, in such a way that on pulling the cap manually the complete or partial breaking of the weakening takes place.
- In accordance with another feature of the invention, the weakening has an open arch shape and the cap comprises a pulling and retention tab, in such a way that, once the bottle has been opened by breaking the weakening, the bottle can be closed again by reversion of the opening movement of the closing part so that the cap covers the formed mouth.
- The present invention also has as an object a grouping of bottles of thermoplastic material, which is essentially characterized in that it comprises a plurality of bottles joined without interruption by their bottom part or base by easily-broken joining straps, made of the constituent thermoplastic material itself of the bottom part of the bottles.
- Another object of the present invention is a grouping of bottles of thermoplastic material, which in essence, is characterized in that by comprising a plurality of bottles and a linkage body of the same, the linkage body being constituted by straps of plastic material and at least one handle part, which links the straps to one another in a continuous manner on which multiple orifices of diameter similar to that of the bottle neck are made, provided with notches radially extending on their periphery, providing the edges of the orifices with a certain flexibility, all in such a way that the bottles can be inserted by pressure in the orifices, remaining held by the effect of the tightening of the edges of the orifices on the bottles' necks.
- The present invention also has as an object, a method of novel concept and function, applicable for the manufacture and filling of bottles and groups of bottles according to that defined in the preceding paragraphs, characterized essentially in that, starting from a sheet of thermoplastic material, it comprises the stages of:
- feeding the sheet of thermoplastic material to a thermoforming machine;
- heating the sheet to a temperature greater than that of the thermofluence of the thermoplastic material;
- inserting a preform punch into a negative mould of the bottle, situated in inverted position, with the sheet interposed between the preform punch and the negative mould;
- conforming the body of the bottle by applying the thermoplastic material against the inner wall of the negative mould, by means of pressure or pneumatic vacuum, and extracting the preform punch from the mould;
- forming the weakening and the sealing portion by splitting of the thermoplastic material by means of a punch;
- filling the bottle with the product to be contained therein by the upper opening which will later be the bottom part or base of the bottle and which remains free because of the withdrawal of the preform punch; and
- thermowelding a sheet of thermoplastic material to the periphery of the aforementioned upper opening, determining the bottom part or base and, the bottle being thus finished and hermetically sealed.
- In accordance with another feature of the method of the present invention, particularly applicable for the manufacture and filling of bottles intended for closing with a screw-on-cap, the method comprises the intermediate stages of applying glue or adhesive between the inner face of the screw-on-cap and the outer face of the sealing portion of the bottle mouth and of subsequently applying the cap to the mouth.
- According to the invention, the stage of applying glue or adhesive and of applying the screw-on-cap can be done simultaneous to the stage of conforming the body of the bottle, for which the cap itself constitutes the bottom part of the negative mould, the threading of the cap forming the surface moulding of the outer threading of the bottle. Alternatively, the stage of applying glue and applying the screw-on-cap is done immediately after stage of forming the weakening.
- According to another feature of the method of the present invention, the method comprises the intermediate stage of applying, by sticking, a top to the outer face of the closing part.
- In accordance with another feature of the present invention, the method comprises, after the thermowelding stage, the stage of separating by cutting each conformed bottle, filled and closed, from the rest of the sheets of the material which constitute the body and the bottom part of the bottles, respectively.
- In the invention it has been foreseen that, for the manufacture of a first type of groupings of bottles, following the thermowelding stage, the stage of separating by means of cutting, each conformed bottle, filled and closed, done in such a way that the linkage body, which comprises a handle, is obtained from the remainder itself of the sheets of the material that constitutes the body and bottom part of the bottles, respectively.
- In another variation of the method, for the manufacture of a second type of bottle grouping, the former comprises the additional stage of forming the grouping, by means of cutting of the sheets of the material that constitute the body and bottom part of the bottles, respectively.
- Those skilled in the art will observe that, the novel features of the bottles disclosed in the present invention, fully guarantee water-tightness for the protection of their content.
- Moreover, the method of the present invention allows for the manufacture by thermoforming and the filling and final closing of the bottles, in a totally continuous process, which consequently can give rise to modular machines and not so long as the current ones, guaranteeing asepsis in the operations and providing greatly reduced operating costs.
- It will be appreciated that with all of that, the present invention manages to give a satisfactory solution to the technical problem raised.

- In the said drawings it can be seen that the
bottles main body 2 and essentially prismatic moulded single-piece, a bottom part orbase 5 and amouth 3. - In FIGS.2 to 14 it is observed that the
bottles portion 6 of themouth 3, which in the closed and full position of the bottle, as it comes out of the factory, is moulded into a single-piece together with thebody 2 of thebottle bottle 1 has been represented, whose sealingportion 6 has been partly broken. - The
aforementioned sealing portion 6 is delimited, as can be clearly seen in the details of FIGS. 3, 4, 6 and 7, by aweakening 7 of the thermoplastic material which constitutes the bottle, made adjacent to the periphery of themouth 3. Theweakening 7 is preferably circumference-shaped, although it can also adopt the shape of other, different curves. In addition, theweakening 7 can be open or closed curve-shaped. - The bottom part or
base 5 of thebottle bottle body 2 and the sealingportion 6. Thebottom part 5 is integral to the lower part of the walls of thebody 2 of thebottle - With the
numerical reference 1, the embodiments of the bottle provided for closing by means of a screw-on-cap 8, are represented, of which particular illustrative examples are shown in FIGS. 1 to 4 and 12 to 14. In this case, the closing by means of the screw-on-cap 6 works with a complementaryouter threading 9 with which theneck 4 of thebottle 1 is fitted. The top 8 is stuck by its inner face to the outer face of the sealingportion 6 by means of an adhesive orglue 11. - Alternatively or complementarily to the top8 and threading 9, the
bottles 1 of the invention can be closed by means of acap 12 constituted by a sheet material, preferentially of a complex of inert and metalized plastic, which is joined to the outer face of the sealingportion 6 by like means of an adhesive orglue 11. The embodiments of the bottles equipped with thecap 12 are represented by means ofnumerical reference 10, and specific examples of them are shown in FIGS. 5 to 11 and 15. - The
bottle bottle weakening 7 breaks totally or partly, unlinking the sealingportion 6 from themouth 3, resulting in the opening of the latter. - In particular, in the case of the
bottle 1 provided with a screw-on-cap 8 and threading 9, the breaking of theannular weakening 7 takes place on unscrewing the top 8, which in its movement drags the sealingportion 6. This is possible thanks to the fact that the adherence of thecap 8 to the sealingportion 6 is greater than the resistance to the breaking by cutting force of the plastic material part of theweakening 7. The result can be seen in the FIGS. 4 and 12. - In the case of the
bottle 10 equipped with top 12, the breaking of theweakening 7 for the opening of themouth 3 is done by manually pulling the top 12. For this, the top 12 is preferably equipped with a pullingtab 13 or a pulling andretention tab 35, which facilitates the operation. In FIGS. 7 and 10 both details are displayed showing the result of this pulling operation. - In FIGS.8 to 11 embodiment examples of the
bottle 10 equipped with top 12 are shown, in which theweakening 7 is in open arc-shape at the ends of which a hinge is determined at the sealingportion 6. In this case, the tab of the top 12 adopts the form of a pulling andretention tab 35, so that, once thebottle 10 is open by breaking of theweakening 7, the former can be closed again, again lowering the sealingportion 6 against themouth 3 and covering with the top 12 the upper part of the bottle adjoining themouth 3. In order to facilitate it, theneck 4 of thebottle 10 comprises at its part adjacent to themouth 3, asplit 40 or a similar formation, adapted for housing part of the pulling andretention tab 35 when the latter is tightened manually against thesplit 40. - In the examples of the
bottles neck 4, thebottles neck 36 which facilitates the exit of the bottle's content. In the case of FIGS. 10 and 11, thebottle 10 is of the type that are closed by means of a top 12 equipped with a pulling andretention tab 35, whereas that of FIGS. 12 and 13, thebottle 1 is of those intended for closing by means of a screw-on-cap 8. - In FIG. 16 a group of
bottles straps 15, which link in a continuous manner with the constituent material of the bottom part orbase 5 of thebottles grouping 14 of bottles. Each of thebottles grouping 14, can be separated from the rest by means of breaking thestraps 15, for which the width of thestrap 15 is small enough to facilitate its breaking. - In FIG. 17 another alternative form of the
grouping 37 of a plurality ofbottles grouping 37, thebottles linkage body 24, constituted by twostraps 38 of plastic material and ahandle part 26, in this example in arched shape or in “half cannon”, which link in a continuous manner to thestraps 38. In thestraps 38 holes 39 are made, one for eachbottle minimum diameter part 41 of thebottle minimum diameter parts 41 can be constituted by a hollow made in thebody 2 orneck 4 of the bottle, or even at the lower edge of a screw-on-cap 8, such as in the case illustrated in FIG. 17. - At its periphery each orifice39 is provided with four
notches 25 extending radially, which provides the orifice edge with a certain flexibility or spring effect. Thebottles neck 4, under pressure in the orifices 39, thenotches 25 facilitating the insertion and remaining held by the effect of the tightening of the edges of the orifices 39 on theminimum diameter part 41 of thebottles - FIGS.18 to 26 show different stages of the method, peculiar to the invention, of the filling and closing of the
bottles groupings - Said method consists of the treatment of a
sheet 16 of thermoplastic material, by means of the sequential phases which are shown below: - feeding the
sheet 16 of thermoplastic material to a thermoforming machine; - heating the
sheet 16 to a temperature greater than that of the thermofluence of the thermoplastic material; - inserting a
preform punch 17 into anegative mould 18 of thebottle sheet 16 of thermoplastic material interposed between thepreform punch 17 and the negative mould 18 (FIGS. 18, 19, 20 and 23); - conforming the
body 2 of thebottle negative mould 18, by means of pressure or pneumatic vacuum, and extracting the preform punch 17 from themould 18; - forming the
weakening 7 and the sealingportion 6 by splitting the thermoplastic material by means of a punch 19 (FIGS. 21 and 22). Thepunch 19 has the shape adapted to the desired conformation of the weakening 7: if this is annular, thepunch 19 will be annular, whereas if it is open-arched, the punch will consequently be open-arched. - filling the
bottle product 22 to be contained therein, by theupper opening 20 which will then be the bottom part orbase 5 of the bottle and which remains free by the withdrawal of thepreform punch 17; and - thermowelding a sheet of thermoplastic material to the periphery of the aforementioned
upper opening 20, the bottom part orbase 5 remaining determined and, therefore, thebottle negative mould 18, under pressure or pneumatic vacuum. - When the
bottle 1 is of the type which is closed by means of screw-on-cap 8, the method comprises the stage of applying glue or adhesive 11 between the inner face of the screw-on-cap 8 and the outer face of the sealingportion 6 of themouth 3 of thebottle 1 and of subsequently applying thecap 8 to themouth 3. - The applying of glue or adhesive11 and of the
cap 8 can be done simultaneous to the phase of conforming thebody 2 of the bottle 1 (FIG. 23). In order to do this, themould 18 is divided in twohalves movable half 34 receives, in a separated position from theupper half 33 and into aslot 42 for which purpose it is equipped, to thecap 8, after which it is situated in continuity with theupper half 33, in such a way that cap 8 itself constitutes the bottom part of the whole of thenegative mould 18. Thus, on carrying out the blowing or aspiration on themould 18, the threading of the top 8 then goes on to constitute the surface mould for theouter threading 9 of thebottle 1. - Alternatively, the stage of applying
glue 11 and applying the top 8 is carried out immediately after the stage of forming theweakening 7. - When the
bottle 10 is intended for receiving a top 12, the method comprises the intermediate stage of applying by sticking, the top 12, to the outer face of the sealingportion 6. This stage of application of the top 12 can be simultaneous to the blowing or aspiration stage. This latter case is that represented in FIG. 19, where it shows thatcap 12 is formed by cutting by means of a clipping 46 from a sheet 47 of a suitable material and next going on to constitute the bottom part of thenegative mould 18 of thebottle 10. - For the formation of
individual bottles sheet 21 to the periphery of theupper opening 20 for the formation of the bottom part orbase 5, whether they are bottles provided withtops 12 or screw-on-cap 8, thesheets cutter 44 in which each conformed, filled andclosed bottle sheets body 2 and thebottom part 5 of thebottles bottles 10 with top 12, in which the same are expelled from the line by anexit duct 43. - FIG. 25 shows the mode of forming the
bottle groupings 14 of FIG. 16. In this case, the die-cutter 44 has the right configuration to separate a cutting from thesheets straps 15 which are joined to thebottom parts 5 of thebottles - FIG. 26 shows the conformation of the
linkage body 24 for the formation of thebottle groupings 37 of FIG. 17. In the example shown, the stage of separating by means of cutting each conformed, filled andclosed bottle aforementioned linkage body 24 is determined directly in the cutting operation itself, starting from theexcess sheets main body 2 orbottom part 5 of the bottles. - Alternatively, the cutting stage for the separation of the bottles individually can give rise to a different cutting from the one shown, so that the
linkage body 24 would finish by means of a cutting operation or subsequent punching out. - The
handle 26 can be subsequently conformed in a final operation, for example by punching out with rollers in order to give it the desired shape. - A person skilled in the art will see that, as well as efficiently solving the technical problem of the present invention, the stages of the method being made known can be performed in modular stations, easily interchangeable for the manufacture and filling of
bottles bottles - Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is hereby stated that everything that does not alter or modify its fundamental principle may be subject to variations in detail.
- In this sense, the method of the invention is liable to incorporate additional stages, such as, for example, the application of a
decorative band 31 to thebottle 1, 10 (FIG. 20). FIG. 20 shows the example in which the application of thedecorative band 31 is done simultaneously to the conformation stage of thebody 2, of thebottle 1, fitted with threading 9. For that, thenegative mould 18 is a mould divided in twohalves lower half 29 that houses the negative of thethreading 9, can be lowered to a position in which it receives thedecorative band 31 in its interior, formed by cutting by means ofknife 32 starting from aroller 30, which can be printed. - Likewise, the
