Definitions
- the present invention concerns a handle for plastic containers, especially of the type that has a flat structure, or laminar format, with a wide central perforation that delimits a grip contour, including a groove in a sector of the handle close to the neck of the container that defines a joint area of smaller thickness, said handle being integral to the body of the container or integral with an annular element that can be coupled by coaxial fit to the neck of the container.
- GB-A-2041286 describes a container of plastic material with an integral handle thereof, as well as a method for producing it, whose method consists of injecting a synthetic resin into a first mold to produce a preform with said incorporated handle and then heating said preform at a suitable temperature, subjecting it to a blow in a second mold to form by expansion the final body of the container.
- This method meant an important advance by allowing the container to be obtained from a preform with its integral handle.
- the type of handle that is specified and illustrated is rigid and extremely bulky with respect to the preform and final container.
- patent application WO-A-82/02369 describes a method for forming a plastic container from blow expansion (at a temperature of about 40 ° C above the transition temperature of plastic to plastic material glass) of a preform previously obtained by injection molding, which includes an integral handle.
- this handle there are a plurality of variants of shapes and sizes, some of them of reduced dimensions, although all of them remain rigid.
- Patent EP-A-0805012 whose holder is the present applicant, describes a method of manufacturing a container of the aforementioned type, in particular of large dimensions (5 liter containers or the like) with an integral handle, obtained at from a plastic material such as poly (ethylene glycol terphthalate) PET, whose handle is characterized in that it is constructed in the form of a sheet with a wide central perforation that configures a grip, arranged so that it protrudes perpendicularly from the body of the preform, incorporating a groove in an area close to its link to the neck that defines an auxiliary thinning to facilitate flexion of the handle.
- a plastic material such as poly (ethylene glycol terphthalate) PET
- This form and arrangement represents a greater ease of use by the user, since by grasping and pulling the handle to lift the container, the handle flexes through said groove, which acts as a hinge, passing from said position perpendicular to the neck of the container to a situation parallel or close to the axis thereof.
- the fact of being formed by a relatively thin flexible sheet also means a material saving for the manufacturer that results in a decrease in costs.
- a handle of the type that has a flattened structure, with a wide central perforation that delimits a grip contour, with a groove in a sector of the handle next to the neck of the container that defines an area of smaller thickness, of articulation, and whose handle, as just indicated, can be integral to the body of the container or integral with an annular element coaxially fit to the neck of the container, with the particularity that in said handle said wide perforation surrounds the neck of the container, or the annular element that fits into said neck.
- the handle thus comprises two arms that extend until they meet in a sector of grip, distal from the area that includes the groove of articulation of the handle to a portion of the body of the container or to said ring.
- the maximum dimensions of the outer edge of said handle, at rest are substantially smaller than the wingspan of the body of said container, thereby avoiding the aforementioned drawbacks, derived from the eventual engagement between handles, in filling preparation operations, when the handle of the container body does not protrude, while that, once flexed, the handle maintains appropriate dimensions for a comfortable grip with one hand and sufficient strength to allow the container and its contents to be lifted and to aid in the operation of pouring it.
- Fig. 1 is a cross-sectional elevation view along line II of Fig. 2, which illustrates in a simplified manner a set of injection molds for configuring a preform with an integral handle in accordance with the present invention, the preform of which is intended for a further blow molding operation to form a container; two sectors of the figure have been expanded for a better understanding of the illustrated details, the figure corresponding to the immediate phase of the injection of plastic material;
- Fig. 2 is a plan view of the handle of Fig. 1 integral of said preform, represented in the situation it adopts located inside the mold assembly of said Fig. 1, after the injection phase;
- Fig. 3 is a partial elevation view of the handle of Fig.
- the handle 1 illustrated in these drawings for containers of plastic material, has a flattened structure, with a wide central perforation 2 that delimits a grip contour 3, with a groove 4 in a sector of the handle 1 close to the neck 5 of the container 6 defining an area of smaller thickness, constituting a hinge of articulation.
- the handle 1 can be integral to the body of the container 6 (Figs. 1 to 3) or integral with an annular element 7 coaxially fit to the neck 5 of the container 6 as illustrated in Figs. 4 and 5
- the wide perforation 2 of the handle 1 surrounds the neck 5 of the container 6 or in the exemplary embodiment of Figs. 4 and 5, to the annular element 7 provided for connection by fit in said neck 5.
- the handle 1 comprises two arms 8a, 8b, in the illustrated exemplary embodiment, which extend until they meet in a gripping sector 9, distal of the carrying area of the articulation groove 4 of the handle 1 to a solidary portion of the body of container 6 or said ring 7.
- the aforementioned formative groove 4 of a hinge-like joint also affects the birth of the two cited arms 8, thereby favoring the tilting of the handle 1 (see Fig. 3) with respect to the body of the container 6, when the latter is lifted so that it is suspended by means of the handle 1.
- the grip profile 3, internal to the perforation 2, is sinuous and thickened, facilitating the seating of the fingers of the hand thereon for its firm grip.
- the handle 1 is integral to the mouth of a preform 10 produced by injection from a thermoplastic material such as poly (ethylene glycol terphthalate), whose preform 10 is provided to obtain the body of the container 6 by a further blowing or bioriented blowing operation of said preform 10 in an appropriate mold, according to the well known method described in the cited patent GB-A-2041286.
- this is characterized in that in a region immediately at the mouth of the semi-molds used in the injection process and that delimit the body of the preform 10 or tube holder 11, a radial passage has been defined 18 for conduction of the injected plastic material towards semi-housings or cavities that make up the handle 1, together with other complementary semi-housings of the formative semi-molds of the neck 5 or neck holders 12.
- Said radial passage 18 has a narrowed transverse portion corresponding to slot 4 that will determine said joint, or hinge.
- the second step 13 for conduction of fluid plastic material communicates with a cavity 17 of the upper semi-molds 12, of narrower mouthpiece than its bottom, so that in said cavity when the plastic material flows and then consolidates, an extractor nail 16 is formed, which during the opening of the molds the remaining material will be dragged and removed in said second conduction step 13, sectioning its joints extreme to the body of the preform 10 and handle 1.
- said semi-housings or cavities of the molds that configure the handle 1 communicate with a device Vacuum generator, whose depression favors the entry of fluid plastic material injected into these cavities.
- the procedure provides for the use in the injection molds of radial capillary passages between the formative cavity of said annular element 7 and the cavity of the region of the handle 1 constituting the grip sector 9 to facilitate the entry of the material fluid plastic injected into said region.
