Definitions

  • the present invention is directly generally to a squeeze bottle package and, in particular, to a squeeze bottle package with an improved construction which is most desirable for the dispensing of viscous products such as toothpaste or the like.
  • dispensing containers for liquids, creams, pastes and other viscous products have been provided over the years
  • dispensing containers for viscous products such as toothpaste or the like present unique problems due to the viscosity of the product to be dispensed thereby.
  • toothpaste is generally provided in collapsible tubes having a removable screw cap.
  • flip-top type caps have been provided for such collapsible tubes.
  • collapsible tubes have proven less than completely satisfactory in that they are often messy, sometimes break, through continued squeezing and rolling, and generally provide an unsightly appearance when left on the sink or vanity.
  • a squeezable container for toothpaste and like viscous products has been introduced.
  • Such squeeze packages are generally oval in shape and stand upright on the counter
  • the container generally includes a screw off cap which, when removed, permits the user to squeeze toothpaste directly out of the container, whereafter the container returns to its original shape after squeezing. No extra packaging is required for such units, except for perhaps a safety seal about the cap to prevent tampering.
  • U.S. Patent No. 4,842,165 issued on June 27, 1989 to Van Coney and entitled Resilient Squeeze Bottle Package for Dispensing Viscous Products without Belching describes and depicts such a squeeze bottle package of the type which has recently been introduced to the market.
  • the Van Coney construction includes an outer resilient squeeze bottle having an inner flexible bag in which the toothpaste is contained.
  • the flexible bag is secured to the interior of the squeeze bottle at its top and approximately at its mid-point to facilitate emptying of the inner flexible bag and improve suckback characteristics.
  • a suckback valve and air check valve are provided as part of the package to regulate the use and flow of air into and out of the package.
  • a squeeze bottle package for dispensing a product contained therein.
  • the package includes a resilient outer container having a squeezable wall and an opening therein.
  • a defor able inner wall is spaced from the squeezable wall in the outer container and has a discharge opening in alignment with the opening in the outer container.
  • a flexible bag having an upper opening is supported in the container by sealingly coupling the bag to the inner wall about the upper opening of the bag.
  • the flexible bag retains the product to be dispensed for discharge through the discharge opening, whereby squeezing of the outer container results in squeezing of the flexible bag and inner wall thereby expelling product through the package opening for use as desired.
  • the inner wall defines an inner wall area which may retain additional product.
  • the inner wall structure and flexible bag construction are removable from the outer container by a consumer to permit replacement thereof in the outer container thereby permitting refills of the package to be provided.
  • Various types of valves for the neck of the bottle are disclosed. In some embodiments, valves are not required.
  • a specially located post preferably having a cross configuration in cross-section, is provided to extend from adjacent the neck of the container into the flexible inner bag.
  • the flexible inner bag collapses about the post while the post directs the product through the discharge opening as the bottle is squeezed.
  • Another object of the present invention is to provide a resilient squeeze bottle package for dispensing viscous products such as toothpaste .or the like which is relatively easy to manufacture.
  • a further object of the present invention is to provide a squeeze bottle package adapted for dispensing viscous products, creams, lotions or the like which is relatively inexpensive to manufacture.
  • Another object of the present invention is to provide a squeeze bottle package for the dispensing of viscous products or the like which permits refills to be used in conjunction therewith.
  • Yet another object of the present invention is to provide a squeeze bottle package for viscous products such as creams, lotions, toothpaste and the like which does not require the use of suckback valves or like elements.

  • Squeeze bottle package 20 includes a resilient outer squeezable wall 24, a base 40 to support the package in upright condition and a removable threaded cap 60 to seal the package during nonuse.
  • resilient outer wall 24 of package 20 preferably has an oval cross-section to facilitate holding and improve appearance, although other shapes may be used. The resiliency of outer wall 24 is determined based on the squeezing characteristics desired.
  • outer wall 24 be readily squeezable and that it returns to its original shape after squeezing.
  • Outer wall 24 is preferably made from a resilient thermoplastic material such as low density polyethylene, but may be formed from other materials, in any of several common methods of thermoplastic molding such as injection molding, extrusion molding, blow molding or the like.
  • outer wall 24 includes a shoulder portion 25, an upwardly extending neck portion 26 having an opening 26a and a flared bottom portion 28.
  • inner structure 30 including a shoulder portion 32 with a central opening 34, an upwardly extending throat 36 having a discharge orifice 38 and a downwardly depending deformable annular side wall or inner wall 50 having memory and defining an inner wall area 50a.
  • side wall 50 extends downwardly for a finite distance along outer wall 24 and is spaced inwardly from outer wall 24.
  • Side wall 50 is preferably molded from thermoplastic materials such that it will return essentially to its original shape after squeezing.
  • a flexible inner bag 80 adapted to be filled with and retain a viscous product 100, such as toothpaste, to be dispensed includes a sealable bottom portion 82 and an upper open end 84 which is appropriately sealed to outer surface 52 of inner wall 50. It is noted that upper open end 84 of flexible bag 80 may be secured to inner wall 50 at any position therealong, even at the lower end of inner wall 50. It is noted that product 100 is also retained in inner wall area 50a defined by inner wall 50 as well as in flexible bag 80. Flexible bag 80 is preferably formed from a heat sealable laminate such as Mylar or the like and is provided with characteristics and features necessary to retain the product therein for the required shelf life. Product can be loaded into the open bottom end of bag 80, whereafter bottom 82 can be heat sealed, as depicted.
  • a viscous product 100 such as toothpaste
  • U.S. Patent No. 4,842,165 discloses various materials and constructions of flexible bag material which may be utilized in the construction of flexible bag 80 for use in the present invention.
  • the bag laminate material may include required barrier materials to prevent loss of viscosity, flavor, smell or active ingredients to retain the freshness and the like of the product contained therein.
  • inner structure 30 is supported in neck 26 of outer container 24 through a tongue and groove arrangement such that throat 36 extends through opening 26a in neck 26 and such that shoulder portion 32 of inner structure 30 lies adjacent to shoulder portion 25 of outer container 24.
  • throat 36 extends through opening 26a in neck 26 and such that shoulder portion 32 of inner structure 30 lies adjacent to shoulder portion 25 of outer container 24.
  • Other coupling methods and constructions can be used.
  • the outer surface of throat 36 is threaded such that cap 60 having inner threads 62 can be threadingly engaged thereon.
  • the first embodiment of the invention includes a suckback valve 120 in the form of a butterfly valve is supported in opening 34 of throat 36 of inner structure 30.
  • Butterfly valve 120 snaps in place in throat 36.
  • Butterfly valve 120 includes opposing displaceable wings 122 and 124 secured to a support 126 through living hinges or the like.
  • a ledge 35 is provided in opening 34 against which wings 122 and 124 rest when in the closed position.
  • the suckback valve while unnecessary for viscous product as explained below, acts to assist in the suckback of product into the container after release of squeezing and regulates airflow back into the package as described in U.S. Patent No. 4,842,165.
  • Base 40 of the package includes a bottom panel 130 which is appropriately secured, by snapping in place or through the use of adhesives, heat sealing or the like to flared end 28 of outer container wall 24.
  • Several openings 132 are provided in bottom panel 130 and an air intake valve 140 is provided over openings 132. This structure acts to control the flow of air on the outside of flexible bag 80 within the package and also affects the suckback characteristics of the device.
  • the Van Coney patent U.S. Patent No. 4,842,165, requires that the inner flexible bag be secured to the inner surface of the outer container wall at the top and midpoint thereof to insure substantially complete emptying of the viscous product contained therein, and to assist in the suckback characteristics at the conclusion of each dispensing cycle. It was this sealing to the inner surface of the outer container that proved difficult and expensive, especially sealing at the midpoint. The present inventor has determined that such sealing to the outer container is .not required if an inner structure, like that depicted and described herein, which includes a soft, deformable side wall which returns essentially to its original shape after squeezing, is provided internally of the package to which the flexible bag is attached.
  • FIG. 3 it is seen that as the hand of a user squeezes the container after removal of cap 60, squeezing outer container wall 24 will cause squeezing of inner wall 50 and flexible bag 80 resulting in product 100 being forced upwardly through butterfly valve 120, wings 122 and 124 of which open, through throat 36 to be discharged through discharge orifice 38 for use.
  • Intake valve 140 shown in Fig. 2 operates in a manner similar to the air check valve disclosed in U.S. Patent No. 4,842,165 such that when the package is squeezed, intake valve 140 will be closed. As the package is released, air will flow through openings 132 to refill the area between flexible bag 80 and container wall 24 with air displaced by the expelled product. Also, in conjunction with the suckback valve, the pressure exerted by the expanding inner wall and container wall will cause suckback of some of the product in the throat back into the flexible bag.
  • flexible bag 80 will begin to close in on itself and extend upwardly into the inner area defined by inner wall 50.
  • the package will assume the position depicted in Fig. 5 where inner bag 80 is essentially completely disposed within the area defined by inner wall 50 thereby permitting essentially complete and total expulsion of the product.
  • Fig. 6 depicts an alternative embodiment of a suckback valve which may be used in the present invention.
  • the suckback valve consists of a single panel 220 which is hingedly secured, preferably through a living hinge or the like, to a stationary panel 222 secured in opening 34 of throat 36.
  • a ledge 235 is provided in this construction for supporting flap 220 in its closed position. Product forced through throat 36 would cause flap 220 to open; suckback will cause it to close.
  • FIG. 7 depicts an embodiment of the present invention in which the package is refillable with a refill cartridge.
  • Package 200 depicted in Fig. 7 is constructed somewhat similar to package 20 depicted in Fig. 2 except for the following:
  • Base panel 230 is removable from outer container 224;
  • Inner structure 230 including flexible bag 280 secured thereon is removable from outer container 224 through base 240;
  • a wing nut 300 removably secures inner structure 230 in the package.
  • a refill cartridge may be used to replace the spent interval unit.
  • cap 260 is removed from throat 236.
  • Bottom panel 230 which contains check valve 340, is removed from base portion 240 of container 224, and wing nut 300 is unthreaded from the lower threaded portion of throat 236.
  • inner structure 230 can then be removed in the direction of arrow A from package 200.
  • Refill package 170 includes an outer cover 172, preferably formed of cardboard, plastic or the like, removably secured to the refill package including inner structure 230 and flexible bag 280.
  • Outer cover 172 supports and houses flexible bag 280 before use of the refill cartridge.
  • refill package 170 can be inserted through open bottom 240 of outer container 224 in the direction of arrow B such that throat 236 extends through opening 227 in container 224.
  • a tongue 301 on the inner surface of container 224 and a corresponding groove on inner structure 230 can be provided for alignment purposes.
  • Wing nut 300 is then secured about the corresponding lower threads on throat 236 as best depicted in Fig. 12 to retain the refill cartridge package in outer container 224.
  • Outer disposable refill cover 172 can then be pulled downwardly in the direction of arrow C to expose the inner structure 230 and flexible bag 280, whereafter bottom panel 230 can be moved -in the direction of arrows D and snapped back on to bottom portion 240 of the container. Accordingly, through the present embodiment, a refillable package is provided.
  • Squeeze bottle package 400 includes a squeezable outer container 402 having a bottom or base portion 404 and an upper throat portion 406.
  • Throat portion 406 extends upwardly from shoulder 405 of container 402 and includes a downwardly extending portion 408 which extends into the interior of outer container 402.
  • An internal collar 420 includes an annular depending side wall 422 to which flexible bag 430 is secured.
  • Flexible bag 430 contains product 100 therein.
  • Internal collar 420 includes a central opening 424 in which a downwardly extending post 426 is supported.
  • Post 426 is in the form of a cross in cross-section as best depicted in Fig. 14.
  • Post 426 acts to direct product through opening 424 into throat 406 through discharge opening 440.
  • Post 426 also acts as a device against which flexible bag 430 can collapse to prevent the bag from totally collapsing along its center so as to permit expulsion of essentially all of product 100 from bag 430, even from the bottom of the bag.
  • an appropriate suckback valve 442 and an intake valve 444 are provided in the package.
  • Figs. 15 and 16 depict an alternative construction of the cross post and supporting structure.
  • package 500 includes a squeezable outer container 502 having a separate shroud 504 with throat 506 secured to squeezable outer container 502.
  • a first mounting structure 510 is supported in opening 512 of shroud 504.
  • a post 520 having a cross shape in cross-section includes an upper mounting portion 522 having a U-shaped cross-section which is secured to mounting bracket 510 as depicted in Fig. 15.
  • Gaskets 600 and 602 may also be utilized for sealing purposes.
  • the present invention provides a resilient squeeze bottle package which can be used for liquids, heavy creams and other viscous products such as toothpaste.
  • the suckback valves described above are preferred.
  • the present inventor has discovered that heavy creams and other viscous products such as toothpaste do not necessarily require a suckback valve.
  • the opening 34 ' in throat 36' may include a reverse taper as depicted to set up the necessary resistance to backflow.
  • opening 34" in throat 36' ' may include offset projections 37 and 39 having beveled edges as depicted which overlap slightly in the longitudinal direction to set up the necessary resistance to backflow.
  • Such a valveless system is most desirable and achievable by the present invention.
  • the degree and manner of the throat restriction, degree of flexibility of the inner wall and container wall, and rate of air intake through the air intake valve on the bottom of the container regulate the suckback characteristics of the valveless system. For example, the more flexible the inner wall and the stronger its tendency to return to its original position after squeezing, the greater the suckback will be. Also, the less air intake through the air intake valve after release of squeezing, the greater the suckback.
  • the present invention thus provides a resilient squeeze bottle package in various forms which overcomes the recognized disadvantages of the Van Coney patent.
  • the inner flexible bag is not sealed or otherwise joined itself to the outer container thereby reducing manufacturing costs, permitting alternative constructions, and allowing for refillable packages and refill cartridges.
  • no suckback valve is required, also resulting in cost and manufacturing savings.
  • the cost and time savings involved in manufacturing the package can be passed on to the consumer either in reduced overall price or by providing a larger package with additional toothpaste without increased cost to the consumer.
