Description

1 CONTAINER WITH A BREAK-AWAY CLOSURE AND METHOD OF FORMING THE SAME
The invention relates to a container, to a method of opening a container, and to a method and apparatus for production of a container.
The prior art comprises containers for flowable substances, for example liquids, each provided with a body of container and with a neck through which the contents may exit after a consumer has acted on some opening means of the container which.
The opening means may comprise opening lines of weakness, for example incisions, or perforations, provided in an end zone of the neck and along which the consumer has to bend, or cut, the material of the neck of the container to remove an outer end part, so opening the container.
However, the operation of opening the container is frequently problematic, since opening along the opening lines of weakness often gives difficulties.
According to a first aspect of the present invention, there is provided a container comprising a container body with wall means defining an outlet zone for contents of said container and weakening means in said outlet zone to facilitate opening of the container by removal of an outer end part of said zone bounded by said weakening means, characterized in that said end part is provided with an appendix projecting significantly outwards from the container body, in such a way as to allow a consumer to grip the same in opening the container .
The appendix, which may project in a longitudinal direction of the container, or in a transverse direction thereof, is advantageously provided by a fin-form weld which peripherally joins together shells of sheet material which form the container.
The shells may be obtained by blow-thermoforming process.
According to a second aspect of the present invention, there 2 is provided a method of opening a container which comprises a container body with wall means defining an outlet zone for contents of said container, and weakening means m said outlet zone bounding an outer end part of said zone, and an appendix projecting significantly outwards from the container body substantially transversely of said container, said method comprising manually gripping said appendix and manually displacing said appendix so as to remove an outer end part of said zone bounded by said weakening means, thereby to open said container.
Owing to this aspect of the invention, the outlet zone can be more easily broken at the weakening means and thus the container more readily opened.
According to a third aspect of the present invention, there is provided a method comprising providing sheet material, advancing said material through forming means, operating said forming means to obtain from said sheet material a container, filling said container with a fluid product, and sealing the filled container, characterized m that before said filling, at least one surface of said sheet material is formed with weakening means .
According to a fourth aspect of the present invention, there is provided apparatus comprising advancing means for advancing sheet material, forming means for forming said sheet material to obtain therefrom a container, filling means for filling said container with a flowable product and sealing means for sealing the filled container, characterized m that, upstream of said filling means there is provided means for forming weakening means m at least one surface of said sheet material.
Owing to these aspects of the invention, it is possible to improve considerably the quality of forming of the weakening means on the container, therefore rendering easier the opening thereof.
In order that the invention may be clearly and completely disclosed, reference will now be made, by way of example to 3 the accompanying drawings, wherein:
Figure 1 is a side view of a container with an appendix extending transversely with respect to the container; Figure 2 is a front view of the container of Figure 1; Figure 3 is a top plan view of the container of Figure 1; Figure 4 is a schematic side view of an apparatus for forming containers each according to Figures 1 to 3; Figure 5 is a section taken along line V-V of Figure 4 ; Figure 6 is a section taken along line VI-VI of Figure 4; Figure 7 is a section taken along line VII-VII of Figure 5; Figure 8 is a section taken along line VIII-VIII of Figure 4 ; Figure 9 is a greatly enlarged fragmentary section of sheet material being incised;
Figures 10, 11 and 12 are views similar to Figures 1, 2 and 3, respectively, but of a container with an appendix extending longitudinally with respect to the container m a direction opposite to the container bottom;
Figure 13 is a schematic side view of an apparatus for forming containers each according to Figures 10 to 12; Figure 14 is a section taken along line XIV-XIV of Figure 13 with incising devices in an open condition;
Figure 15 is a top plan view of Figure 14, but with the incising devices m a closed condition.
As shown in Figures 1 to 3, a container 2 comprises a bottom part 4, side walls 6 and a neck 8 whereby a flowable product may exit from the inside of the container 2. The container 2 has been formed by peripheral welding together and blow- thermoforming of two parts of sheet material, so that the side walls 6 are m the form of shells joined together along a peripheral weld 10 which bounds the neck 8, which is initially closed. From the weld 10, which is m the form of a fin, an appendix 12 and re-closmg means 14 project, the re- closmg means 14 being joined to the weld 10 by a tie 16. At the base of the appendix 12, i.e. between it and an intermediate zone of the neck 8 which comprises the tie 16, the neck 8 has a pair of incisions lines 18, which lie in a 4 plane perpendicular to the longitudinal axis of the neck 8. The lines 18 do not pass through the thickness of the sheet material which forms the container 2, but sufficiently into the thickness of the material as to weaken it to a considerable extent. When the container 2 is to be opened, it is sufficient for a consumer to grip the appendix 12 and, slightly turning it m the direction shown by arrow F about a longitudinal axis T of the appendix 12, so as to twist the appendix, pull it outwards, to make the sheet material break along the incision lines 18.
As shown m Figure 4, an apparatus for forming groups 20 of the containers 2 from sheet material 22 comprises in succession; a forming station 24, wherein moulds, not shown, deform the sheet material 22 by the action of a forming fluid, a cutting station 26 for cutting each group of containers 20 from the sheet material 22, a filling station 28 for filling the containers 2 with a flowable product which is introduced into mouths of the necks 8 through filling injectors 29, a sealing station 30 for sealing the filled containers 2 by sealing means not shown, and a punching station 32 for punching the individual containers 2 from the group of formed, filled and sealed containers 20. Indexing means, not shown, advance the sheet material 22 in the direction of the arrow FI and further indexing means, not shown, advance the groups 20 of containers 2 towards the punching station 32 m the direction of the arrow F2. Upstream of the forming station 24 there are provided continuous incising devices 34 which cut into the outer surfaces of the sheet material 22, so producing therein the incisions 18, in the zone of the sheet material 22 wherein the necks 8 are to be provided, before the sheet material 22 is welded and blow-thermoformed at the forming station 24. As shown m Figures 5 to 8, the incising devices 34 comprise a pair of opposing blades 36, each mounted on a support 37 fixed to an oscillating shaft 38 protruding from a block 40 fixed beside the sheet material 22. 5 There are further provided guiding means 42 for guiding an edge of the sheet material 22 while the blades 36 incise the sheet material 22 at a predetermined distance from the same edge.
Upon each shaft 38, at that end thereof opposite to the end fixed to the blade 36, a resilient means 44 acts, which is adjustable by a screw 46 and presses on a lever 48 fixed to the arm 38. Therefore the force transmitted from the resilient means 44 is exerted by the arm 38 onto the sheet material 22 so as to produce the incision by the blade 36. Figures 10 to 12 show a container 2a provided with an appendix 12a which extends m a direction away from the bottom 4 while widening with respect to a longitudinal axis of the container 2a. An incision 18 is produced around a gorge 50 of the neck 8 to facilitate the opening of the container by a consumer acting on the appendix 12a and extends m a plane perpendicular to the longitudinal axis of the gorge 50.
Figure 13 shows an apparatus similar to that of Figure 4, but m which there is provided, between the severing station 26 and the filling station 28, an incising station 52 wherein intermittent incising devices 54 incise the sheet material 22 of the containers 2a which have been formed but have not been filled yet.
The incising station 52 comprises cylindrical plungers 56 which are advanced in the direction of the arrow F3 to enter through the open necks 8 and later withdrawn to a location remote therefrom after the incisions 18 have been produced. As shown m Figures 14 and 15, the intermittent incising devices 54 comprise heated incising blades 58 fixed to supports 60 which are movable m the directions of the arrows F4 to come into contact with a zone of the neck 8 along the gorge 50 when the groups 20 are stationary, and to withdraw to a location remote therefrom to allow the already incised group 20 to be transferred to the filling station 28 and a not yet incised group 20 to arrive at the incising station 6 52 .
As shown in Figure 15, the heated incising blades 58 have a planar form shaped according to the form of the necks 8.
