Definitions

  • This invention is related to plastic containers for liquids wherein the contents are removed by cutting, piercing, puncturing or otherwise perforating the closure rather than by the usual practice of removing the closure.
  • the container of our invention may have many different applications with various types of flowable liquids, it is particularly applicable to the handling of hazardous liquids, generally in quantities of a gallon or less.
  • the cap In use. the cap is removed and the contents manually poured from the bottle. When the cap is removed, the worker is exposed to possible contact with the hazardous liquid. Instances of serious personal injury, including disfigurement, have resulted from such contact.
  • a typical usage is encountered in the electronics industry where semi-conductor devices are immersed in a Hydrogen Peroxide and sulfuric acid bath to strip off protective coatings applied at an earlier stage of fabrication.
  • the present method involves pouring the liquids into the bath from an open bottle and manually dipping a basket containing the devices into the bath. The worker exposure to potential injury is appreciable.
  • One method of discharging the contents of the container of the present invention without exposing a worker to danger, and to control the rate of discharge, is based on the use of a cooperating chamber sized to receive the container of hazardous liquid in the inverted position.
  • a receptacle in the chamber sized to fit the neck of the bottle is fitted with a perforating device to open the bottle.
  • a liquid reservoir is located below the container chamber.
  • the container closure When the container closure is perforated, the liquid flows from the bottle as air or other gas enters through the perforation to balance the pressure.
  • the liquid level rises to seal the mouth of the container, however, no more air enters the container, and the discharge of liquid stops as the gas pressure above the liquid level in the container, plus the hydrostatic head of liquid, equals the atmospheric pressure.
  • the liquid level of the reservoir falls below the neck of the bottle, air or gas enters and further liquid discharge occurs until the liquid level again seals the mouth, hence the liquid is not only discharged but discharged at a controlled intermittent rate to any operation to which the chamber is attached.
  • one embodiment of the container of the present invention permits the escape of pressurized gas and vapor without the loss of liquid, by employing a vapor permeable membrane, impermeable to liquids, and generally supported by impermeable films having one or more slits or other minute openings for passage of gas or vapor.
  • the inner closure of the container of the present invention with its primary liquid seal is easily applied during the filling operation but once tightened in place it is locked on by the engagement of ratchet teeth encircling the bottle neck with protrusions extending inwardly from the skirt of the inner closure, thus thwarting any misguided attempt by a worker to handle the new package by the previous method of unscrewing the cap.
  • the outer closure or overcap pro tects the perforatable plate (liner or wafer) against premature puncture, and also provides a secondary liquid seal.
  • means are provided in the outer closure, such as a small opening, for the escape of such vapor or gas.
  • the present invention is directed to a container for flowable liquid mate rials comprising a reservoir for containing the material having a cylindrical hollow neck extending from the reservoir.
  • the upper portion of the neck carries a male thread.
  • a readily perforatable plate is provided for placement over the end of the neck or the mouth of the container in a sealed relationship. This plate constitutes the primary liquid seal.
  • a multiplicity of ratchet teeth at least partially encircle the cylindrical neck below the male thread.
  • An inner screw closure, including the perforatable plate is provided, having a female thread for engaging the male thread on the neck of the container, said innerclosure extending down over the neck of the container a sufficient distance to at least partially encompass the ratchet teeth.
  • This inner closure also exposes a portion of the sealed perforatable plate so that it is accessible for perforation.
  • the inner closure has additionally a multiplicity of protrusions projecting inwardly for cooperation with the ratchet teeth, said ratchet teeth being oriented with respect to the engaging threads so that when the inner closure is screwed on, the protrusions engage the ratchet teeth to permanently retain the inner closure in a sealed relationship with the mouth of the container.
  • the hollow neck is enlarged below the ratchet teeth to accept an outer closure, said outer closure being sufficiently capacious as to completely enclose the inner closure, and having an annular surface for tight-fitting contact with a matching annular surface on the enlarged portion of the hollow neck, thus providing a secondary liquid seal.
  • FIG. I is a partial view of the bottle neck of the preferred embodiment shown in elevation, with a cross section of its inner closure directly above.
  • the inner cylindrical surface of the skirt of the cap is shown with protrusions extending inwardly to engage ratchet teeth on the bottle neck. in this instance, the ratchet teeth do not completely encircle the neck. but rather there are two diametrically opposite groups of seven ratchet teeth.
  • a single ply, readily perforatable plate, or cap liner, is shown exposed by a central opening in the top of the capv
  • FIG. 2 is a plan view of the bottle neck of FIG. 1, showing the two groups of ratchet teeth partially encircling the neck.
  • FIG. 3 is a partial view in elevation of one embodiment of the plastic container with both inner and outer closure in place.
  • the ratchet teeth completely encircle the neck, and as further frustration to anyone attempting to remove the locked or inner closure, it is shown with a left hand thread.
  • This container is further characterized by having an off-center neck to minimize the danger of adding the incorrect ingredient to a process.
  • FIG. 4 illustrates one type of readily perforatable plate designed to permit the release of pressurized vapor or gas.
  • lt comprises a gas-permeable membrane sandwiched for support between two wafers of impermeable film, which however, have small slits to permit passage of any gas permeating the inner membrane.
  • FIG. is a partial perspective view of another embodiment of our invention wherein the bottle neck is encircled with pyramidal ratchet teeth sloping upwardly from the cylindrical surface in the direction of rotation of the closure when applied and also extending outwardly from the surface of the neck in the direction away from the mouth of the container.
  • the third and locking surface of each pyramidal ratchet tooth lies substantially in a plane which includes the axis of the containers neck.
  • the closure of the same figure also shown in perspective directly above the neck in cross section, has inwardly projecting protrusions which in this variation are inwardly directed pyramidal ratchet teeth for cooperation locking engagement with the oppositely directed ratchet teeth of the containers neck.
  • FIG. 1 The bottle for liquids of the preferred embodiment of the present invention is fabricated of polymeric material, and comprises first, a reservoir 1 for containing the liquid, only the upper part of which is shown. It includes a hollow neck 2 extending from the reservoir and in communication therewith forming the neck and mouth 3 of the bottle for the charge and discharge of fluids.
  • the hollow neck has on the upper portion of the outer cylindrical surface, a male thread 4.
  • a thin plate 5 for placement over the mouth 3 of the bottle in sealed relationship therewith, is a readily perforatable liner or wafer, also of polymeric composition, preferably having a thickness of no more than about 0.06 inch.
  • This plate may be a single ply of impermea ble film for sealing in liquids which do not liberate appreciable vapor or gas, or of a gas permeable membrane which is impermeable to liquids if vapor or gas is to be liberated.
  • perforatable plate 5 comprises permeable membrane 6 sandwiched between two wafers of impermeable film 7 having tiny slits 8 therethrough.
  • the hollow neck 2 has concentrically disposed below the male thread 4, and at least partially encircling the neck, a multiplicity of ratchet teeth 9.
  • these ratchet teeth are arranged in diametrically opposed groups. They could as well consist of single teeth uniformly positioned about the neck or groups of two or more, preferably spaced at substantially equidistant points about the neck. The ratchet teeth can also completely encircle the neck as in FIG. 3.
  • An inner closure or screw cap 11 for the bottle preferably of polymeric composition, serves to retain perforatable plate 5 against the mouth of the bottle when said closure has been applied and tightly secured to the bottle neck.
  • the perforatable plate and inner closure are one, in that the perforatable plate lies in the inner closure or cap as a liner.
  • the top of the inner closure has an opening 12 substantially coincident with the mouth of the bottle, to provide access to the perforatable plate.
  • the perforatable plate is merely the top of the inner closure itself, which has been molded thin enough to be readily perforatable.
  • this perforatable section of the inner closure is less than about 0.06 inch in thickness.
  • the skirt 13 of the inner closure extends downward to envelope the upper portion of the hollow neck and to at least partially encompass the ratchet teeth 9.
  • This inner closure has additionally, a multiplicity of protrusions 14 projecting inwardly from the lower inner cylindrical surface of the skirt beneath the female thread. in FIG. 1 they are shown as short ribs, but they may take other forms, as for example, inwardly projecting ratchet teeth for cooperation with those of the neck.
  • the ratchet teeth are oriented with respect to the threads of the neck and closure, so that the closure may be screwed on to retain the perforatable plate in a liquid seal relationship with the mouth of the bottle.
  • the closure may be screwed on to retain the perforatable plate in a liquid seal relationship with the mouth of the bottle.
  • the ratchet teeth may either completely or partially encircle the neck as in FIGS. 3 and 1, respectively, there are at least two reasons why partial encirclement may be preferable.
  • partial encirclement can provide greater flexibility by allowing slight distortion of the closure, hence easier application of the inner closure to the bottle.
  • FIGS. 1 and 2 the ratchet teeth are shown in diametrically opposed groups of seven, the number included in a group is not critical. A fair number in each group is preferable, however, as for example, from three to seven, so that no appreciable degree of back-off of the inner closure, once tightened, is possible.
  • the holow cylindrical neck is enlarged in diameter below the ratchet teeth, said enlarged portion 15 being substantially cylindrical.
  • This enlarged portion carries a right hand male thread 16.
  • An outer closure or screw cap 17 of H6. 3 is provided, having a female thread 18 for engagement with the right hand male thread 16.
  • This outer screw cap is sufficiently capacious to completely envelop the inner cap ll, and has an annular surface 19 for liquid tight contact with the matching annular surface 21 on the enlarged portion of the neck.
  • the outer cap or closure is also provided with means for permitting escape of the vapor or gas passing the primary seal.
  • a small hole 22 in the outer cap serves to vent the closed space between the inner and outer closure to permit the escape of vapor or gas.
  • the bottle may be fabricated of any suitable polymeric material, polyethylene or polyisobutylene are especially preferred. This also applies to the inner and outer closure and to the perforatable plate, although in the case of the latter a wide variety of materials are suitable both for the gas permeable membrane and the impermeable films.
  • the material selected will depend on the nature of the liquid being packaged, but polyethylene is especially preferred, and can be obtained in both gas permeable and impermeable form.
  • the ratchet teeth 9, arranged in groups of seven, are relatively small, to provide many points of engagement with the protrusions in the lower part of the skirt 13 of inner closure 11.
  • the ratchet teeth are also slightly truncated to reduce the amount of required lift of the ribs over the ratchet teeth without reducing their strength.
  • a bottle is shown with an off-set neck and an indented hand-hold 23.
  • the neck would be centrally located, but an off-set neck can be of value in making sure that only the proper bottle is discharged into a particular operation.
  • the receiving chamber for the bottles was shaped to accomodate only this bottle, one could not inadvertently charge in the wrong material, even if supplied in a bottle which was similar except for the off-set feature.
  • FIG. 3 also shows a bottle wherein the outer removable cap has the usual right hand thread, but the inner, non-removable closure has a left hand thread.
  • the inner cap is locked on, with the ratchet teeth in this case sloping upwardly from the neck in a counter-clockwise direction, and cannot be removed because of the ratchet, anyone attemping to unscrew the thread, and assuming a right hand thread had been used, particularly as the outer cap has a right hand thread, would unknowingly attempt to turn the closure in a direction to tighten it further.
  • gas permeable membrane 6 having a thickness ranging from about 0.0005 to 0.005 inch is sandwiched between impermeable films 7, each of which has a thickness ranging from 0.015 to 0.025 inch, which films, however, permit the escape of gas through slits 8.
  • impermeable films 7 each of which has a thickness ranging from 0.015 to 0.025 inch, which films, however, permit the escape of gas through slits 8.
  • any type of opening or a multiplicity of openings can be used providing they are very small, so that the degree of support desired is not sacrificed.
  • FIG. 5 The perspective drawing of FIG. 5, with the inner closure shown in cross section, portrays still another embodiment of our invention wherein the ratchet teeth 9 encircling or partially encircling the neck are pyramidal in form, sloping outward and upward from the neck in the direction in which the inner closure is to be turned on tightening. These pyramidal teeth also slope outward from the neck in the direction away from the mouth of the bottle.
  • the inward protrusions 14 from the skirt of the inner closure are shown as cooperating, inwardly extending ratchet teeth, these could alternately be ribs. ln this modification, the skirt of the inner closure flares outwardly to form a conical surface and conform to the slope of the ratchet teeth 9.
  • This inner conical surface of the skirt 13 would carry the ribs, spaced to cooperate with the ratchet teeth, and extending downwardly and outwardly on the conical surface.
  • the ratchet teeth, both on the bottle neck and in the closure can be discontinuous and grouped in accordance with molding requirements.
  • a benefit of this form is to increase the area of contact between the protrusions and the ratchet teeth, hence to increase the strength of the lock obtained on tightening the closure.
  • the lower portion of the skirt of the closure becomes thinner, thereby providing flexibility and resilience to increase the ease of application of the closure to the bottle.
  • these pyramidal ratchet teeth can also be truncated as with the ratchet teeth of FIG. 2, thus increasing the ease of applying the cap still further, without appreciable loss of strength of the lock obtained.
  • a polyethylene bottle with a special neck finish This neck has, at the top, a threaded finish. Below this threaded finish the neck is fitted with ratchets on two opposite sides. Below the ratchets the diameter of the neck is enlarged producing an unthreaded section terminating in a flat area, at which point the neck is further enlarged and equipped with a second threaded area.
  • An inner closure, or screw cap, sized to fit the upper threaded section of the neck finish described above is used.
  • This cap is designed with a skirt fitted with locking ribs which engage the ratchets of the neck finish, permitting turning of the cap in the tightening direction only.
  • the configuration of the ratchets on the neck of the bottle prevent removal of this cap.
  • a 34 inch circular opening is provided in the top section of this cap.
  • a 0.04 inch thick plastic liner is inserted in the cap prior to application to the bottle. This liner makes the primary seal.
  • a composite liner is inserted in the cap prior to application to the bottle.
  • This composite liner consists of a 0.001 inch thick polyethylene membrane permeable to vapor but not to liquid, sandwiched between two 0.02 inch thick impermeable polyethylene liners, each of the latter having a 0.1 inch long slit in the center.
  • the vapor per meable liner prevents liquid leakage when the package is inverted and placed in a receiving chamber.
  • the slit liners are to provide physical strength to prevent rupture of the permeable membrane by the weight of the liquid.
  • the slits are to permit passage of vapor.
  • An outer screw cap is provided, sized to cover the entire neck of the bottle including the permanently installed inner cap described above.
  • This outer closure or overcap is threaded at the bottom to fit the lower thread on the neck finish and is designed with a flat annular sealing area positioned to mate with the corresponding flat annular sealing area on the neck finish which is located below the encircling ratchet teeth.
  • the overcap is removed and discarded exposing the permanently attached upper cap described above.
  • the bottle is inverted and placed in a container chamber of a machine with the neck protruding through an appropriately sized opening into a reservoir below.
  • a pre-positioned, sharp metallic probe contacts the exposed plastic liner in the inner screw cap, puncturing the liner.
  • the liquid then flows into the reservoir by gravity, stopping when the liquid level seals the neck of the bottle.
  • the plastic bottle of the present invention when emptied as above at a controlled rate, offers the following advantages:
  • the primary seal is protected from accidental puncture during transportation by means of a protective overcap.
