Abstract
A pillow or sachet disposable dispenser in which a container has a relatively rigid flexible spine adhered to an inside surface of one of the flexible sheet that form the container with a protrusion extending through an aperture in the sheet. The protrusion has a line of weakness that will rupture when flexed providing an opening through which the material in the container can be expelled.
Description
- The invention relates to disposable containers known as pillow or sachet containers.
- Improvements in dispenser packages are shown in U.S. patents to Redmond, U.S. Pat. Nos. 3,986,640 and 4,493,574 and 4,611,715 and 5,494,192. In particular in U.S. Pat. No. 4,611,715 a stiff flat sheet defines one side of a dispenser package and a product containing-pouch that includes a pair of laterally spaced pockets containing flowable product defines another side. The stiff flat sheet has a protrusion in the shape of an elongated pyramid. The stiff flat sheet has a fault line that extends all the way across including across the elongated pyramid. When the package is bent the fault line ruptures across the stiff flat sheet. By further bending and squeezing the pockets, the flowable material in the pockets is expelled out of the fault line opening and/or out of the protrusion opening (as described in U.S. Pat. No. 4,493,574).
- The structure of and the problem presented in dispensing flowable product from a pillow or sachet is discussed in U.S. Pat. No. 5,494,192.
- The present invention is an improvement in the design of a dispensing package in which conventional pillow or sachet packages are equipped with a dispensing channel.
- In one aspect the invention comprises a pillow or sachet container made of first and second flexible sheets joined at their periphery to define a cavity for containing flowable material to be dispensed. Adhered to the inside surface of one of the sheets is a spine made of a more rigid but flexible material that has a protrusion in it. The protrusion extends outwardly through an aperture in the first sheet and it has a line of weakness across it. In use the container is flexed generally about the line of weakness so that it fractures leaving open the portion of the protrusion on each side of the line of weakness that then define an opening through which the flowable material can be expelled from the container.
- In a further aspect the protrusion is symmetrical about a longitudinal dimension of the container.
- In a further aspect the protrusion is symmetrical about a lateral dimension of the container; and in a still further aspect the protrusion is symmetrical about both a longitudinal and a lateral dimension of the container.
- In a further aspect the protrusion begins at opposed distal points along the longitudinal dimension and it gradually rises to a point of meeting at a highest point. The line of weakness extends across the protrusion at the highest point.
- In a further aspect the line of weakness is limited to traversing the protrusion.
- In a further aspect the protrusion is an elongated pyramid with the line of weakness traversing laterally it at its peak,
- FIG. 1 is an exploded view of an embodiment of the invention.
- FIG. 2 is a sectional view through A-A as seen in FIG. 1.
- FIGS. 3a and 3 b show progressively the flexing of the container to expel its contents.
- FIGS. 4a through 4 d show alternative configurations of the spine element of the invention.
- Referring to FIGS.1-3 b the present invention comprises a pillow package 10 (also called a sachet package) having
flexible sides periphery 16 and are formed in a pillow shape to define aninterior space 18 that is filled with flowable material to be dispensed. One of theflexible sides 12 is formed with anaperture 20, which in this embodiment is diamond shaped, generally centrally located in theside 12. A third element, aspine 22 is made of relatively rigid flexible material. Thespine 22 has aflat base portion 24 and aprotrusion portion 26. Theprotrusion portion 26 is hollow inside it so as to facilitate flow of the material as will be understood. Theflat base portion 24 of thespine 22 has afirst surface 28 and asecond surface 30 Theprotrusion portion 26 is in the shape of an elongated pyramid commencing from opposite distal points definingconverging channels second surface 30 from theirdistal ends weakness 42 extends across theprotrusion portion 26 at the highest point where theconverging channels weakness 42 crosses. In the preferred embodiment the line ofweakness 42 does not extend beyond theprotrusion portion 26 laterally across theflat base portion 24, thereby leaving theflat base portion 24 flexible. - When assembled the
spine 22 is inside the package, adhered to aninner surface 44 of theflexible side 12, positioned so that theprotrusion portion 26 extends through theaperture 20. Theaperture 20 is a diamond shape to match the shape of theprotrusion portion 26 where it joins thebase portion 24. Thespine 22 can be adhered by any suitable adhesive material that is compatible with the use of the package. - The
package 10 is made by forming thesides side 12 having theaperture 20 cut into it. Then thespine 22 is adhered to theinner surface 44 of theside 12 and thesides sides - The
protrusion portion 26 as shown has an elongated pyramid shape. Other shapes can be selected that rise from opposed distal points meeting at a highest point with the line of weakness extending across the protrusion at the highest point. A shape for the protrusion is preferably symmetrical about the longitudinal dimension of the container. Another preferred shape is symmetrical about the lateral dimension of the container; and a still further preferred shape is symmetrical about both the longitudinal and the lateral dimension of the container. Further the protrusion should be configured so that the line of weakness cross it transversely to the longitudinal dimension of the container and the protrusion is symmetrical on each side of the line of weakness so that when the container is flexed to rupture the line of weakness a flow channel is provided on each side leading to an opening between them. - FIGS. 4a-4 d show alternative shapes for the
spine 22, in particular for thebase portion 24 and for theprotrusion portion 26. The outline of thecontainer 10 is shown in dash lines to provide a sense of the relative size of the various spine shapes. - In use the flowable material inside the
package 10 is dispensed as shown in FIG. 5. Dispensing is accomplished by bending thepackage 10 as shown by the arrows A and B. With the bending, the line ofweakness 44 will fracture establishing openings 46 and 48 at the highest point of theelongated pyramid 30,and as the package is further bent and compressed the flowable material inside will by dispensed through the openings. - It can be appreciated the line of
weakness 44 can be formed by a variety of means including for example by scribing or by molding the line of weakness into the spine when it is made. - It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments shown and described herein and that variations may be made that are within the scope of the accompanying claims and equivalents thereto without departing from the principles of the invention.
- Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art, and consequently it is intended that the claims be interpreted to cover such modifications and equivalents.
