Claims.
This invention relates to bellows type dispensing containers for powdered materials. One object of the invention is to provide a means for resiliently expanding the flexible walls of a container so that by intermittent compression of the container walls the contents may be discharged in a fine spray with some degree of force.
'Ihe invention may be fully understood from the following specification when read in connection with the accompanying drawing in which Fig. 1 is a perspective View of a container partly cut away to show the interior and an expansion member in operating position;
Fig. 2 is a perspective view of an expansion member fiattened toshow its conformation;
Fig. 3 is a side View in perspective of the expansion member in a compressed position;
Fig. 4 is a perspective View of an alternate form of the invention; and
Fig. 5 is a perspective View of a separator for the expansion member.
Referring to the drawing and in particular to Fig. 1, numeral I denotes an envelope container for powder, numeral 2 the powder contents and and numeral 3 an expansion member. The envelope I may have a flap 4 at one end through which the expansion member may be inserted and the envelope be lled. After the container has been filled this ap may be secured in a conventional manner, as by glue or the like, in order to seal the envelope against escape of powder or air during use except in the manner provided for. A partially perforated portion may be provided at one corner of the envelope and flap as at 5 in order to permit easy removal of that portion to provide a discharge opening for the container.
The expansion member 3 illustrated in Figs. 2 and 3 consists of a generally rectangular flat sheet of a material such as fiber or paper board, slightly narrower than the container in'which it is to be used, which may be formed of laminations disposed longitudinally of the sheet. For the purpose of illustration, in these gures a 1aminated sheet is shown which is deformed, by scoring or impression, eccentrically and laterally of the sheet to create a substantially U-shaped groove 6 therein forming a hinge joint 'I having divergent arms 8 and 9 of which one arm is substantially equal in length to the length of the container. However, the sheet may be scored at a midpoint thereon to form arms of equal length and some of the advantages will be retained. When the arms 8 and 9 are compressed as shown.
in Fig. 3, due to the deformation of the sheet, a force is exerted on the laminations, individually and collectively, which tends to stretch them longitudinally of the hinge joint and to compress them laterally thereof. Further, flexure of the member 3 tends to cause a separation of the laminations laterally along the edges of the groove 6 at points IIJ and I. As the material used for member 3 may be only slightly extended the force exerted at the hinge joint 'i and tending to stretch the material is strongly resisted. Likewise, as in manufacture the material has been compressed'to only slightly less than the maximumv extent, strong resistance to compression is also developed. The resistances developed in such manner are translated into a spring action of the expansion member 3 which is further augmented by the resistance of the laminae to separation. When a one .piece or unlaminated sheet is used similar stresses are set up within the material itself and comparable results may be obtained.
Ordinarily the width of the groove 6 is just sufficient to cause the edges thereof, IU and II, to bear against one another to form a fulcrum for the arms, but if desired the groove may be widened so that when the arms 8 and 9 are compressed, the edges Il]v and II bear against the bottom ,of the groove. 'Ihe reaction in either case is similar.
The expansion of member 3 Within the envelope I deforms the envelope sufficiently to create a hollow space therein which forms a powder and air pressure chamber suitable for the purpose desired.
In order to increase the resistance of the eX- pansion member to compression and facilitate more rapid action thereof, a substantially nonresilient separator I2 (Fig. 5), having a thickness slightly greater than that of the slot I3 formed by the groove 5 when the arms 8 and 9 are pressed toward each other, may be inserted in the groove. The separator I2 functions to increase the leverage of the arms 8 and 9 thereby increasing the effect of the reaction when the arms are released and causing faster return of the device to its normal position. A suitable element is illustrated in Fig. 5. The separator is maintained in an operative position within the groove by the edges IB and II thereof, as illustrated.
An alternate form of construction is illustrated in Fig. 4 according to which the expansion member 3 consists of a flat sheet of fibrous material having grooves 6 impressed in its surface adjacent Vto form arms Sand 9.
each end, spaced therefrom and Afrom each other The arms 8V and 9 are connected by the hinge joints 1, formed by means v spring action of the member is'initially somewhat container as is illustratedin Fig. 1.
To operate the device, a corner of the conmore rapid. Y Y p Y In use, a container ofY the type described is lled with powder and the Vexpansion member in- 'serted preferably with the'hinge joint 'l adjacent the filling and discharge opening and the end 0f the longer arm against theY other end of the tainer may be removed and, byexerting intermittentmanual pressure upon the sides of the envelope to iex the arms 81and 9 of the expansion Vmember; a current of air maybe forced through the opening made at 5 whichy will discharge the powder in the container in a ne stream or-spray. As-pressure on the envelope is intermittently released, a stream of air is drawn into the container by the suction created when the expansion member springs back to its normal position. This incoming current of air will effectively agi- Ytate the powder ,and prevent the discharge of powder in lump form.
The foregoing description is for the purpose of illustration only and the invention is not to be limitedby any theories or examples contained therein but only bythe accompanying claims in which it is desired to claim all novelty inherent in the invention.
' I claim:
