Description

CHILD RESISTANT CONTAINER AND CLOSURE ASSEMBLIES
The present invention relates to a container comprising a container neck with an external thread, and a closure with an internal thread adapted to engage the external thread of the container neck to bring the container from an open condition to a closed condition and vice versa, in which said external thread extends along at least a part of the periphery of the container neck, in which the closure comprises a closure skirt and a securing member which at a first section is hingedly connected with the closure, and which has a second section opposite relative to said first section, and in which a catch embodied in the safety element in the closed position of the container is adapted to be brought into engagement with a recess in the container neck in order to thus obtain a secured condition, in which turning of the closure relative to the neck of the container is prevented, and in which the securing member is received in and kept in the closure, the closure comprising means for engaging corresponding means in the second section of the securing member.
So-called child-proof containers for preventing children from getting access to the contents of the container are known in many different embodiments. The principle of the child-proofing resides in that opening of the container demands a combination of operations which are beyond the motoric capability and strength of the child, like for instance simultaneous or subsequent pressing and turning, squeezing and turning, etc., but which without any greater difficulty may be done by grown-ups.
A container of the type mentioned by way of introduction is known from DK patent no. 159,542. The securing member for this container is only kept in the closure by the friction between the engagement means on the closure and the securing member, respectively. It may be tempting or obvious for the child to try to lift the securing member, following which the closure may simply be screwed off.
Child-proof closures, which are locked in the closed condition of the container, are among others known from US-A- ,838,441 and US-A-4,790, 42 which disclose a securing principle comprising deformation ot the closure for release of locking means, following which the closure may be lifted and pressed up to an open condition. As it iε thus only the closure which is lifted to give access to the content, the container may be inadvertently opened, as deformation and lifting may take place in one and the same condition. Thiε has the effect that it becomes necessary to put great demands on the rigidity of the closure, so that children cannot open it on account of having too little strength, which on the other hand means that persons with reduced movability and strength of the fingers, like for instance rheumatic sufferers, cannot easily open the container. The last-named fact induces people to refrain from activating such a precautionary measure.
In US-A-4 ,209, 100 it has been tried to solve the problem of unintentional opening of the container by retaining a closing flap hingedly connected with the closure in a recess in the closure by means of fric¬ tion-increasing pairs of protrusions/recesses in the closed condition of the container. The locking flap itself is released from the recess by deformation of the closure, whereby the free end of the locking flap sclosurees upwards on an oblique surface into a slight¬ ly upstanding position, in which it may be caught, preferably by means of a nail, and subsequently lifted, the protrusions being simultaneously disengaged from the recesseε. Even though this closure provides an improved child-proof locking, it sufferε from the same drawbacks aε do the two US patents mentioned above, viz. that a good movability of the hands is required to release the locking flap, and that direct access is given to the content of the container when the closing flap iε lifted.
On thiε background it is the object of the present invention to improve a container of the type mentioned by way of introduction such that the handling thereof is sufficiently intricate to prevent a child from opening the container, the forces necessary and the required dexterity for the opening not being unattain¬ able for a grown up with reduced finger strength and dexterity.
Thiε object is met according to the invention by a container, which is characterized in that the closure further comprises an external closure portion with a closure skirt and a top section for receiving the securing member in the secured condition of the con¬ tainer, that the engagement means of the closure are designed as a protrusion extending from the closure skirt of the external closure portion for locking engagement with a protrusion extending downwards from the securing member near or close to the free end of itε second section, and that the locking engagement between the protrusions can only be released by defor¬ mation of the external closure portion in predetermined deformation zones in the secured condition of the container in order to thus release the securing member from its εecured condition for the attainment of the closed condition of the container.
In a container according to the invention unin¬ tentional opening is substantially prevented, as handling of the container both requires several con- secutive operations as well as a combination of move¬ ments which are practically speaking impossible for a child to figure out and carry through, but it is at the same time still easy to open and close again for a grown up. As the locking engagement is released by deformation of the external closure portion solely, the inner closure portion may be made with arbitrary rigidity and thickness to meet the strict requirements in respect of among others imperviousness which are made within the field of use of the container, whereas the external closure portion may be made with relative¬ ly less rigidity in order to increase deformability and thus user comfort.
Advantageous embodiments of the invention are stated in the dependent claims.
The invention will now be explained in detail in the following by means of some examples of embodiments and with reference to the schematic drawing, in which Fig. 1 shows a segmental perspective view of a container in a first embodiment of the invention in closed condition,
Fig. 2 at a larger scale a segment of a lateral view, partially sectional, of the container in Fig. 1 in secured condition, Fig. 3 a εegment of the container in Fig. 1, εeen from behind,
Fig. 4 a plane view of the cloεure for the con¬ tainer in a second embodiment, seen from above in undeformed and deformed condition, Fig. 5 a segment of the container in Fig. 1 in closed condition, seen from the εide,
Fig. 6 a segment of a perspective view of the container in a further embodiment of the invention in closed condition, and Fig. 7 at a larger scale a segment of a lateral view, partially in section, of the container in Fig. 6 in secured condition.
Figs 1-5 of the drawing εhow a container 1 for εtoring for instance medicine in form of pills. The container 1 has a body portion 2, which at the top is finished by a container neck 3, and a closure, gen¬ erally designated 4. The container neck 3 has in the embodiment εhown an external thread 5 with a flap 3a fixedly connected with the container neck, but the thread may also be made on a separate thread piece for connection with the container neck or on the very container neck.
The closure 4 has an internal closure portion comprising a closure skirt 6, in which an internal thread 7 is provided for engagement with the external thread 5, and a top section 8 closing the neck of the container 3 when the closure 4 is screwed on. The top section 8 is in view of an improved detainment in and sealing of the container neck provided with an addi- tional skirt 6b positioned radially within the skirt 6, εaid additional skirt protruding in the closed condi¬ tion of the container downwards into the container neck. The closure 4 haε outεide the internal closure portion an external closure portion with a cloεure skirt 9 and a top section 10. A securing member 11, which in the embodiment shown is rod-shaped, is at a firεt section lla at itε one end 12 hingedly connected with the closure 4 and provided with a weakening line 13 for the formation of a hinge joint 14, on which a catch 15 is provided, the function of which will be explained in detail in the following. The top εection 10 of the external closure portion iε provided with a depression 16 for receiving the securing member 11.
In the situation shown in Fig. 2 the container 1 is in its secured position, i.e. it cannot be opened without releaεe of the safety function. The closure 4 iε prevented from being screwed off the neck of the container 3 due to the fact that the catch 15 on the securing member 11 extends through a hole 6a in the internal closure skirt 6 and into a not threaded portion 17 (shown most clearly in Fig. 3) in the external thread 5 of the container neck 3. Attempts to turn the cloεure 4 relative to the container neck 3 will reεult in the catch 15 after a few degreeε of turning meeting the thread 5.
To be able to disengage the catch 15 and thus bring the container in a condition, in which it iε just closed, the securing member 11 haε to be εwung about its axis of rotation at its one end 12. The securing member 11 is, however, locked by means of an additional safety lock at itε εecond section lib, an engagement means in form of a protrusion 18 on the closure portion of the external closure portion being in engagement with a correεponding protruεion 19 on the εecuring member 11. The protruεionε 18,19 have hook-εhaped partε facing each other with abutment surfaces 21a, 22a, which in the condition shown are substantially parallel with each other and with the top portion 19 of the closure. To facilitate closing once more the protrusionε 18,19 may in connection with the abutment εurfaceε 21a,22a be provided with oblique scloεureing εurfaceε 21b,22b.
The engagement between the protrusions 18,19 may only be released through deformation of the outer closure portion in predetermined deformation zones under simultaneous lifting of the end of the securing member 11 which is εituated cloεeεt to the protruεion 19. In Fig. 4 the closure 4 is shown in soclosure lines in undeformed condition and with dotted lines in its deformed condition, in which the hook part on the protrusion 18 is disengaged from the hook part on the protrusion 19. The deformation zones may be arranged in the skirt 9 or in the top section 10, and are preferab¬ ly marked with an indication which may be visual in form of a word mark, or perceptible, like for instance a raised area. In view of facilitating deformation the top section 10 may as εhown in Fig. 4 be provided with slits 20 or it may, as indicated in Fig. 1, be bellow- shaped or with weakening lines so that this portion may be easily bent. The opening of the container takeε place in the following way: The closure 4 is deformed by pressing with the thumb and forefinger of one hand in the areas marked by arrows A, whereby the areas marked B move outwardε until the poεition εhown by intermittent lineε in Fig. 4 haε been reached. By the other hand the securing member 11 iε lifted and swung to the position shown in Figε 1 and 5. The container is now in its closed condition and is opened by screwing off the closure 4 from the neck of the container. The securing member 11 may at the screwing off be uεed aε a lever, which iε an advantage when a perεon suffers from reduced mobility and strength of the hands, as by opening he may for instance grasp the container body with both hands and place the securing member in abutment with the edge of a table or the like and subsequently unscrew the closure by turning the con¬ tainer body itself. Closing and securing of the con¬ tainer takes place in reverse order.
In the embodiment shown in Fig. 6 a container 31 is shown in its closed, but not εecured condition, i.e. in which the closure 34 has been εcrewed onto a body part 32. The container ends as before with a container neck 33 with a flap 33a, in which the external thread 35 has been provided. The closure 34 comprises an internal closure portion with a closure skirt 36 with an internal thread 37 and an additional skirt 36b extending downwards into the neck of the container, and a top section 38. Radially outside the internal cloεure portion an external closure portion with a closure skirt 39 and a top section 40 is provided. The εecuring member 41 is like in the embodiment described above designed aε a rod-shaped part and is in a first section 41a at its one end 42 hingedly connected with the closure 34. As the hinge connection is situated at the top section of the closure 34 there is in this embodi¬ ment no weakening line in the securing member 41. The catch 45 iε here placed in the second section 41b of the securing member 41 close to the engagement means 49. In the top section 40 of the external closure portion there iε in the same way aε deεcribed above a depression 46 for receiving the securing member 41 in its secured condition.
Aε most clearly shown i Fig. 7 the catch 45 is in the secured condition of the container in engagement with a recess 47 in the upper surface of the neck of the container, the catch 45 being passed through a hole 38a in the top section of the internal closure εkirt.
The protrusions 48,49 are made in the same way as in the embodiments in Figs 1-5 with the exception that the hook part on the protrusion 48 of the closure skirt is directed radially outwardε and the hook part on the protrusion 49 on the securing member radially inwardε. The abutment surfaces 51a, 52a are also here parallel with each other and with the top εection 40. The deformation zoneε have been established thereby that on each side of the portion of the closure εkirt 39 εituated below the εecuring member a slit 53,54 has been made, which slit extends perpendicularly to the top section and which may have resilient bands which are in connection with the remaining part of the closure skirt 39. In this way the whole pitch-circle- shaped portion between the slits becomes so to speak hinged at the bottom and may by a radial inward pres¬ sure release the engagement means from each other, following which the securing member 41 may be lifted for the attainment of the closed position of the container, and the closure 34 subsequently be screwed off from the container. Closing and securing of the container are made by similar operations but in reverse order.
