Description
«1 CONTAINER AND LOCK OUE HAS AN OUTER COVER OF METALLIC PAPER
This invention relates to containers having an outer envelope of metallic paper over their lock, in particular to fluid containers, as spilled liquids. The containers for fluids, ie drinks like? fruit drinks and liquors, are commonly bottles, or have the shape of bottles, which have a closed neck with a lock with screw cord. The lock may have a metallic paper cover extending over the lock and partially over the neck as a way to provide evidence of attempted violation, and to improve the image of the product. An example of the container and lock of this type is the container used for the fruit juice concentrate sold as RIBENA ™. When the container is opened, it is sometimes difficto break the foil, but the production methods make it difficto perforate the metal foil cover for easier removal. U.S. Patent Number: 4538740 discloses a sleeve that fits with shrinkage on a container lock, and has a longitudinal row of weaknesses, i.e., aligned in the axial direction of the bottle on which it is placed. adjust
It is an object of this invention to provide a container and lock in which the aforementioned diffices are solved. In one aspect, the present invention provides a container having a neck and a mouth through which the contents of the container are dosed, having a lock for the mouth having a rope for mating with the corresponding rope in the neck, and which is rotated relative to the container to open, having the
container a metal paper cover extending beyond the edge of the lock to lie against the wall of the container; the lock having a skirt portion descending around the neck toward the base of the container, characterized in that the lock has one or more projections
external ones that pierce or weaken the metallic paper cover when rotating the lock. Conveniently the content may be a fluid, such as a spillable liquid, for example the aforementioned beverages. Typically the lock is a screw rope cap lock having an upper portion that seals against the lip of the mouth and a skirt portion with rope that is hooked with complementary cord over the wall of the container or neck surrounding the mouth. discharge mouth.
The strings can be a conventional screw cord,
"but alternatively there may be other ways of twisting and removing, for example when the skirt of the lid and the wall of the container have cooperative cam surfaces instead of screw strings." The term "strings" used in the present invention includes both cords as cooperating cam surfaces To break, or weaken by the formation of grooves, a metal paper cover applied to this lid, t a plurality of external projections 0 may be provided on the skirt portion of the lid. these one or more projections are accommodated in the lower edge of the lock, to encourage the metal paper to be cut around the bottom edge, to resin a clean cut edge Typically a plurality of 5 projections can be accommodated in one or more rings around the outer surface of a circular lock, typically in a single * flat ring, typically around the lower edge of the These projections are formed integrally in a convenient manner during the molding of a plastic cap. The projections preferably have a section with respect to planes parallel to the axis of rotation, which is decreasing outward, that is, converges towards a point remote from the lock, for example, wedge-shaped, to give a cutting action or chisel against a wraparound metallic paper cover 5 as the lock is rotated.
ßr The shape and number of projections can be varied to suit the weight and thickness of the metal foil cover, and the torque that is expected to be applied, to open any particular lock / bottle combination. Preferably the shape and size of the projections is such that they do not present a danger of damage to a user's hand when opening the container. Those skilled in the art readily apply this design restriction. For example, it may be convenient to form the edge
forward (when unscrewed) of the projections as an inclined surface, or curve for an increased cam or wedge action, and to improve cutting efficiency, although projections have been found to be substantially rectangular in plan in a
plane perpendicular to the axis of rotation. The projections can be provided in the form of a projection serrated towards jk, outside, for example crenellated or in saw teeth in plane, edge, although adapted to the curvature of the edge around the lower edge of the lock. The lock described above, provided for a container of this invention forms another aspect of this invention. According to the above, the present invention also provides a container cover that has
rope to mate with the corresponding rope in the
? r * neck of a container, and which rotates relative to the container to open, the lock having a skirt portion descending around the neck toward the base of the container, characterized in that the lock has one or more external projections that pierce or they weaken a metallic paper cover that extends beyond the edge of the lock to lie against the wall of the container when the lock is turned. A preferred embodiment of this container lock comprises a lock having an upper portion sealing against the edge of a container mouth, and a skirt portion descending around the neck towards the base of the container carrying rope or cam surfaces that they are hooked with ropes or complementary surfaces of the neck of the container surrounding the discharge mouth, characterized in that the skirt portion has one or more projections extending radially outward, preferably a plurality of projections lying on a common circumference. The convenient and preferred features of the container lock of this aspect of the invention are as described below. The container can be a glass bottle or plastic material with a screw neck, and the rope in the lock can be hooked with the cords in the neck of the neck.
that bottle directly. Alternatively a rope adapter, conveniently made of plastic material, can be fitted around the neck of the container, and can be extended axially to form the edge of the mouth. The 5 cords in the lock can be hooked with the cords in the adapter. The use of such an adapter facilitates the inclusion of other features, for example, filters, anti-drip characteristics, evidence of additional violation,
Jßt etcetera, and can also facilitate the use of a rope with
a small step so that the lid rotates a substantial amount during removal so that the projections have ample opportunity to exert their weakening or piercing effect on the foil. These adapters are known per se, for example in the bottle
RIBENA ™ mentioned above, but the use of the lock described herein with such an adapter is novel. The metallic paper cover can be a conventional metallic paper cover like the one used in bottles known as the RIBENA ™ bottle, and can cover the
the entire external surface of the lock and extend downwards to also cover adjacent parts of the neck and walls of the container. The embodiments of the invention will now be described, only by way of non-limiting example, with
reference to the accompanying drawings. In the drawings:
- Figure 1 is a schematic cross-section through a lock with a screw cord and a metallic paper cover, fitted directly on the neck with a bottle's screw cord; Figure 2 is a sectional view of part of a lock of the invention fitted on an adapter on the neck of a bottle; Figure 3 is a fragmentary cross-section through jj through the skirt of the lid of Figure 2, in enlarged scale. Figure 4 is a partial sectional view of the lower edge of the lock of Figure 3, with respect to the line B-B of Figure 3. With reference to Figure 1, a bottle 1 of
glass or plastic, for example for a fruit drink, has a conventional mouth 2 on the neck of the bottle 3. A
M plastic screw cap lock 4 (general) has a skirt portion 5 with an internal cord 6 that engages a corresponding cord 7 on the outer wall
from the neck of the bottle 3 just below the mouth 2. The cooperation cords 6, 7 allow the upper portion
8 of the lid lock 4 is sealingly engaged against the edge of the mouth 2, to seal the container 1. A circular piece of metal paper 9 is placed in the lock of the lid 4 after filling and closing the lid.
p bottle 1 with the lock. A brush action sweeps the metal paper 9 around the neck 3 of the bottle 1 so that the metal paper 9 covers the lid lock 4 and is pressed firmly against the neck 3 of the bottle 1. 5 The lid lock 4 has a single ring of outwardly extending projections 10, which form a serrated edge projecting outwards, around the periphery of the lower edge of the skirt portion 5. When the lid lock 4 is gripped through 0 the metallic paper cover 9 and rotates with respect to the longitudinal axis AA of the container 1 to open, the projections 10 cut the metallic paper cover 9 pressed against the cover 9, either by perforation or at least to weaken it in the line 11. This allows the user to break the metal paper cover 9 as lid 4 is removed without undue effort, and also provides the advantage that the cut metal paper cover 9 has an edge. the cut neatly. With reference to Figures 2, '3 and 4, a bottle 12 of glass or plastic, for example for a fruit drink, has a neck 13. Attached around the neck 13 in a liquid-tight seal is an adapter of material plastic 14 that together with the neck 13 forms the edge of the mouth of the bottle (which is not shown). The bottle 12 and the adapter 14 have a conventional construction. "
plastic screw cap lock 15 (general) has a skirt portion 16 with an inner cord 17 which engages a corresponding cord (not shown) on an external wall of the adapter 14. The internal profile of the lock 15 corresponds closely to the adjacent external profile of the adapter 14. The cooperating cords allow the upper portion 18 of the lid lock 15 to be sealingly engaged against the edge of the mouth, to seal the container 12. A circular piece of metallic paper 19 ( shown in partial section in Figure 2) is placed in the lid lock 15 after filling and closing the bottle 12 with the lock. A brushing action sweeps the metallic paper 19 around the neck 13 and the adjacent parts of the wall of the bottle 12 so that the metallic paper 19 covers the lid lock 15 and is pressed firmly against the neck 13 and the adjacent parts of the lid. the wall of the bottle 12. The lid lock 15 has a single ring of outwardly extending projections 20, "which form a serrated edge projecting outwards, around the periphery of the lower edge of the skirt portion. 16. When the lid lock 15 is grasped through the metal paper cover 19 and rotated with respect to the longitudinal axis AA of the bottle 12 to open, the projections 20 spit the metal paper cover 19 which
'is pressed against the lid 19, either to perforate or at least to weaken it on the line 21. This allows the user to break the metal paper cover 19 as the lid lock 15 is removed without undue effort, and 5 also provides the advantage that the cut metal foil cover 19 has a sharp cut edge on the line 21. As shown in Figure 3, the projections 20
W have a section, with respect to planes parallel to the axis of
rotation A-A, which decreases outwards, for example wedge-shaped, at an angle ¿of approximately 30 ° with respect to the horizontal and a thickness t at the tip of approximately 0.1 mm. As shown in Figure 4 the projections are substantially rectangular in plan, and extend
a radial distance r of approximately 0.5 millimeter from the outer surface of the skirt portion, jAj giving the lower edge of the lock 4 a serrated edge of crenellated shape although adapted to the curvature of the lock. It is convenient that the circumferential length c of
Each projection around the periphery of the skirt is approximately 1 millimeter with a gap width w of approximately 0.75 millimeters between each projection 20. The projections 10 of the lock 4 of Figure 1 have a shape, arrangement and dimensions similar to those of Figures 3
and 4. The projections 20 extend radially
approximately 0.5 millimeters beyond the surface of the adapter 14 immediately adjacent to and below the lower edge of the lock 15. Similar dimensions would be expected appropriate for the projections 20 of other shapes.
