Description
5~3 - 1 - UL~9o 5c~ f o~ ,~ O~5~/v5~ v/~ V/~U~ fg/~
~3 ~a/S J~e ~5~
~ his invention relates to a closure Eor containers for storing and dispensing moist tissues or the like ana more particularly to a container closure adapted to maintain the tissues in the container in a moist condition over a long period. ~he tissues are stored in the container in continuous rolled or folded length sui-tably perforated at spaced transverse lines to provide separable tissues of appropriate size~ Such con-tainers are referred to as dispenser-containers hexeinafter.
Generally dispenser-containers have included an opening in one wall of the container in the :Eorm of a straight or cros.s shaped s].it through which tissues may be drawn~ A
problem with these prior art dispenser containers is that a portion of tissue to be next extracted necessarily protrudes through the slit opening and sometimes separates the edges of ~3 the slit to a considerable extent. This separation allows some escape of the evaporable fluids with which the tissue is impregnated in its moist state.
An object of the present invention, thereoxe, is to S provide a closure for a dispenser-container that reduces direct escape to atmvs~here of the evaporable moistening fluids by comparison with conventional slit wall cQntainers.
The invention provides a closure for a dispenser-container mouth comprising an inner and outer diaphragm each with an opening therethrough completely out of register with each other at least one of the diaphragms having a substantially planar portion, a frusto conical wall portion extending from one o~ the diaphragms in the direction of said planar portion in the other of the diaphragms -to terminate in a free end forming the opening in the diaphragm which is resiliently sealed by the planar portion of the_other diaphxagm.
~i.'~S~
_ 3 _ U490 The frustoconical wall portion can be in the outer diaphragm, the frustum providing a recess in the top of the diaphragm in which the free end of the next extracted tissue can be contained and readily gripped between the users fingers..
~ he frustoconical wall portion can be resilient, a particularly good seal being achievable between the contact zone rimming the opening at the free end of the frustum and the other diaphragm.
~o minimise the risk of the frustoconical wall portion being inverted in use the frustoconical wall portion is preferably a frustum of an oblique cone.
~ he opening in a diaphragm can be provided with an edge flange exte~ding along at least part of the edge of the opening to mi~imise the risk of tearing the tissue as it is pulled through the opening.
A convenient construction is to provide an inner diaphragm adapted to snap engage the mouth of a container and an outer diaphragm adapted to snap engage with the ;nner diaphragm. An external snap fitting cap can be provided for covering the opening in the outer diaphragm between uses to reduce the dr~ing up of the protrudiDg free end of the next extracted tissue.
~ way of example an embodiment of the inven~ion will now be described with reference to the accompanying drawings in which~
~igure 1 is a plan view of a closure with the cap in the open position, part of the outer diaphragm beIng cut away to show the inner diaphragm;
~igure 2 is a partly sectioned side elevation of the closure along the line II-II of ~igure 1 applied to a container and with the cap closed, and ~igure 3 is a sectional view taken on the line III-III of ~igure 1 and appears on the same sheet as that 35 view.
~1`
L L~ 3 _ ~ ~ U490 ~he illustrated closure is shown applied to -the mouth of an open topped, tub-like container 4 having a detent rib 5 around -the mouth.
The closure comprises a s-tiff or rigid inner diaphragm 5 6 which itself comprises a planar central portion 7 and a char~el-shaped, circumferential flange structure8 having an outer detent rib 9 and an inner detenk rib 10~ '~he outer detent rib 9 snap fits over the de-tent rib 5 o f`
the mouth of container 4 so as to secure the diaphragm thereto in hermetic engagement -therewith.
~he cen-tral portion 7 of diaphragm 6 has an opening 11 formed in it of more or less elliptical shape. ~he curved edge of the opening 11 nearer to the center of the diaphragm is defined by a downwardl~ directed flange 12 integral with the diaphragm~
An ou-ter diaphragm 13 is made of an elastomeric or resilient plastics material~ The outer diaphragm has a planar portion 14 from which a resilient frustoconical wall portion 15 extends to terminate at the free end in an elliptical opening 16 forming the opening through the diaphragm 13 having a rim 17. The frustoconical por-tion 15 is a frustum of an oblique substantially elliptical cone so that the inclined surface surrounding the opening 16 is of varying width from place to place about the periphery of the openingO
The outer diaphragm 13 is secured in place by means of a detent rim flange 18 having a detent rib 19 thereon which snap ~its into the inner detent rib 10 of the flange structure 8 the outer diaphragm.
When secured in posi-tion rela-tive to -the lnner diaphragm -the rlm of -the opening 16 in the outer diaphragm resiliently contac-ts the planar portion 7 of` the inner diaphragm, the rim 17 of the opening f'orming the continuous contact zone surrounding the opening 16 in only the outer diaphragrn and not surro~mdirlg or o~erlapping the opening 11 in -the inner diaphragm.
~he resilient engagement of -the rim of the opening 16 with the inner diaphragm forms a substa~tially hermetic seal of the opening 16 to seal the container.
~L4~V3 _ 5 _ U490 An outer closure cap 20 is secured to the flange structure 8 of the inner diaphragm by an integral hinge 21. '~he lid is a snap fit in the closed position with the closure and presents not only a pleasing appearance when the container is closed bu-t also fur-ther assists in rendering the entire closure a herme-tic seal t'or the mouth of the container.
In use -the container has a folded leng-th of -tissue shee-t packed within it and may have a moistening fluid which may be scented as desired, The tissue sheet is suitably perforated at spaced apart transverse lines to provide separable tissues of appropriate size.
~he free end of first tissue -to be extracted is compressed and extended through the opening 11 in the inner diaphragm and under the rim 17 of the opening 16 which is completely out of register with the opening 11 to be held thereby in pressure contact with the central planar portion 7 of diaphragm 6. The ~ree end o~ the length o~ tissue is then disposed subs-tantially as shown in ~igure 3 in the recess formed by the frustoconical wall portion 15 where it can be readily gripped by the user. ~issues may be withdrawn as desired by gripping the free end of the tissue next to be extracted and pulling it awa~ from the container through opening 16.
When a tissue is being withdrawn a portion of the next tissue will be pulled under the rim 17 of opening 16 as a result of resilient deformation of the fructo-conical portion of diaphragm 1~ before the first mentioned tissue tears away, thus rendering the next tissue ready for removal.
As the length of tissue enters the opening 11 in the ~ er diaphragm it rubs over the flange 12 a-t the edge of the opening 11, the flange 12 guarding against the tissue being torn against the relatively sharp edge of the opening 11 which would be presented to the tissue in the absence of the ~lange 12.
~3 Pulling the tissue th~ough the opening 16 in the outer diaphragm tends to cause -the frustoconical portion to invert but this risk is reduced because the frustum is that of an oblique cone.
Whilst dependant on the -thickness and compressibility of the tissue~ and the resiliency of the diaphragm, the closure provides an impro~ed sealing of the container to minimise the e~aporation or drying out of the tissues~
~etween uses the sealing is further improved by closing the cap 20.
Other embodiments of the invention are of course possible in which a frus-toconical wall portion, resilient or rigid, can be pro~ided o~ one or both of the diaphràgms.
When the frustoconical por-tion is rigid the necessary resilience to obtain the desired seal can be obtained either from resilience elsewhexe in the diaphragm or in the other diaphragm. Subs-tartially flat diaphragms can be used one or both of which may have contact ~ones surrounding or rimming the openings One or other of the diaphragms may ~e integral with -the container closed thereby.
Closuresaccording to -the in~ention may be applied to any form of container, including those of a pliable or flexible nature.
