Abstract
Description
- This invention relates to a closure for containers for storing and dispensing moist tissues and more particularly to a container closure adapted to maintain the tissues in the container in a moist condition over a long period. The tissues are stored in the container in continuous rolled or folded length suitably perforated at spaced transverse lines to provide separable tissues of appropriate size. Such containers are referred to as dispenser-containers hereinafter.
- Generally dispenser-containers have included an opening in one wall of the container in the form of a straight or cross shaped slit 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 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.
- In French document FR-
A-22241 10 there is disclosed a dispenser-container closure cap having an opening and pivoted flap snappingly held in place therebelow. Depending upon the weight of the web to be dispensed the flap can overlap the opening to form a tortuous path of travel for the web. - In French document FR-A 2 367 434 there is disclosed a self-closing closure for dispensing flowable material having a diaphragm member and a central member which can be rotated relative to one another to prevent flow through the closure, the diaphragm having a frustoconical sleeve which is closed by a stem extending outwardly from the central member. The closure of this disclosure is intended to be fitted to a flexible container which can be squeezed to dispense the contents and would not be suitable for dispensing a continuous web of tissues.
- An object of the present invention, therefore, is to provide a closure construction for a dispenser-container suitable for web of different weights and which reduces direct escape to atmosphere of the evaporable moistening fluids by comparison with conventional slit wall containers.
- The invention provides a closure for a dispenser-container mouth comprising a diaphragm having an opening therein formed by the free end of a frustoconical wall portion and resiliently sealed by a closure member movable relative thereto characterised in that the closure member is formed by a second diaphragm having an opening therethrough completely out of register with the opening formed by the free end of the frustoconical wall portion and a planar portion which resiliently seals the opening formed by said free end.
- The frustoconical wall portion can be in the outer diaphragm and inwardly inclined towards the inner diaphragm so that the frustum provides 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 user's fingers.
- The 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.
- To minimise the risk of the frustoconical wall portion being inverted in use the frustoconical wall portion is preferably a frustum of an oblique cone. The opening in a diaphragm can be provided with an edge flange extending along at least part of the edge of the opening to minimise 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 inner diaphragm. An external snap fitting cap can be provided for covering the opening in the outer diaphragm between uses to reduce the drying up of the protruding free end of the next extracted tissue.
- By way of example an embodiment of the invention will now be described with reference to the accompanying drawings in which
- Figure 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;
- Figure 2 is a partly sectioned side elevation of the closure along the line II-II of Figure 1 applied to a container and with the cap closed; and
- Figure 3 is a sectional view taken on the line III-III of Figure 1.
- The illustrated closure is shown applied to the mouth of an open topped, tub-
like container 4 having adetent rib 5 around the mouth. - The closure comprises a stiff or rigid
inner diaphragm 6 which itself comprises a planarcentral portion 7 and a channel-shaped,circumferential flange structure 8 having an outer detent rib 9 and an innerdetent rib 10. The outer detent rib 9 snap fits over thedetent rib 5 of the mouth ofcontainer 4 so as to secure the diaphragm thereto in hermetic engagement therewith. - The
central portion 7 ofdiaphragm 6 has anopening 11 formed in it of more or less elliptical shape. The curved edge of the opening 11 nearer to the center of the diaphragm is defined by a downwardly directedflange 12 integral with the diaphragm. - An
outer diaphragm 13 is made of an elastomeric or resilient plastics material. The outer diaphragm has aplanar portion 14 from which a resilientfrustoconical wall portion 15 extends to terminate at the free end in anelliptical opening 16 forming the opening through thediaphragm 13 having arim 17. Thefrustoconical portion 15 is a frustum of an oblique substantially elliptical cone so that the inclined surface surrounding theopening 16 is of varying width from place to place about the periphery of the opening. - The
outer diaphragm 13 is secured in place by means of adetent rim flange 18 having adetent rib 19 thereon which snap fits into the innerdetent rib 10 of theflange structure 8 the outer diaphragm. - When secured in position relative to the inner diaphragm the rim of the
opening 16 in the outer diaphragm resiliently contacts theplanar portion 7 of the inner diaphragm, therim 17 of the opening forming the continuous contact zone surrounding the opening 16 in only the outer diaphragm and not surrounding or overlapping the opening 11 in the inner diaphragm. The resilient engagement of the rim of the opening 16 with the inner diaphragm forms a substantially hermetic seal of the opening 16 to seal the container. - An
outer closure cap 20 is secured to theflange structure 8 of the inner diaphragm by anintegral hinge 21. The lid is a snap fit in the closed position with the closure and presents not only a pleasing appearance when the container is closed but also further assists in rendering the entire closure a hermetic seal for the mouth of the container. - In use the container has a folded length of tissue sheet 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.
- The 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 theopening 16 which is completely out of register with the opening 11 to be held thereby in pressure contact with the centralplanar portion 7 ofdiaphragm 6. The free end of the length of tissue is then disposed substantially as shown in Figure 3 in the recess formed by thefrustoconical wall portion 15 where it can be readily gripped by the user. Tissues may be withdrawn as desired by gripping the free end of the tissue next to be extracted and pulling it away 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 frustoconical portion ofdiaphragm 13 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 inner diaphragm it rubs over theflange 12 at the edge of theopening 11, theflange 12 guarding against the tissue being torn against the relatively sharp edge of theopening 11 which would be presented to the tissue in the absence of theflange 12. - Pulling the tissue through 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 dependent on the thickness and compressibility of the tissue, and the resiliency of the diaphragm, the closure provides an improved sealing of the container to minimise the evaporation or drying out of the tissues. Between uses the sealing is further improved by closing the
cap 20. - Other embodiments of the invention are of course possible in which a frustoconical wall portion, resilient or rigid, can be provided on one or both of the diaphragms. When the frustoconical portion is rigid the necessary resilience to obtain the desired seal can be obtained either from resilience elsewhere in the diaphragm or in the other diaphragm. Substantially flat diaphragms can be used one or both of which may contact zones surrounding or rimming the openings.
- One or other of the diaphragms may be integral with the container closed thereby.
- Closures according to the invention may be applied to any form of container, including those of a pliable or flexible nature.
