9 Claims.
This invention relates to improvements in means for distributing pulverulent material in a diifused. form. -'The invention is particularly concerned with a dispensing container for materials such as insecticide powders or talcum powder, which container may also provided an attractive sales package for the material.
A principal object of the invention is to provide a simple and efficient dusting apparatus in it) which the powdered contents may be distributed as a spray, as diffusion of dust in air, under pressure provided by the bellows action for which provision is made in'the structure disclosed.
Other objects and advantageous characteristics of the invention may be fully understood from the following description when read in conjunction with the accompanying drawings, in which Fig. 1 is a perspective view of a preferred form of the invention with parts broken away.
Fig. 2 is a perspective view of a blank from which the container body may be formed.
Fig. 3 is a perspective view of a blank from which another form of the invention may be produced.
Fig. 4 is a perspective view of a container, with parts broken away, to show an auxiliary support for the container walls.
Fig. 5 is a perspective view, with parts broken away, of a container of alternate shape, showing an auxiliary support for the walls thereof.
Referring first to Fig. l, the reference numeral l designates the body of a substantially cylindrical container which, as shown, has been formed from a convolutely wound sheet of a flexible material such as kraft paper, cloth, or the like, which may or may not be impregnated or treated to render it water-proof or moisture resistant. If desired, however, the body portion l may be formed of a plurality of nested concentric members, but in either instance, the body is one having laminated walls in which the laminations 2 extend longitudinally thereof.
Rigid or semi-rigid cap members 3 and 4, made of stiffened paper, a moulded material, metal, or the like, are firmly secured to the body I in such manner as to impart a degree of stiffness to the end portions of the body. One of the cap members, as 3, may be provided with an opening 5 having a removable closure such as beaded plug 6. If such an opening is not originally provided, it is desirable that a puncture point be indicated on the cap 3, by a stamped circular indentation or a printed marking. so that the original user may make the opening required for operation of the container as a dispenser.
Although it is possible to maintain the form and. rigidity of the container by means of the cap members 3 and 4,'and a label encircling the 5 body portion, it is preferred to use adhesives, other interliners, or both, between laminations for such purposes. Fig. 1 and-Fig. 2 show four points at'which adhesives may be applied. When the tube is formed by convolute winding of a 10 sheet I2, such as shown in Fig. 2, the adhesive may be applied to outer surface I of the inner end of the sheet,- to the inner surface 8 of the outer end of the sheet, and to the inner surface of the sheet along the edge portions 9 and I0 15 thereof, from the outer end toward the inner end for such distance as may be determined suitable to accomplish the degree of stiffness desired.
The width of the adhesive bands applied to the edge portions may also be varied according to the 20 stiffening effect desired, but normally each band will be from one-fourth to one-third of the length of the container body. The governing factors in any case are the nature of the material used to form the container body, the rigidity which may 25 be imparted to the assembly by the type of closures used, and. the degree of serviceability which may be desired in the finished container. On occasion, it may also be desirable to use a combina-, tion of materials to form the container body. 30 For example, a sheet of Cellophane or other material, even cloth, may be superimposed on a sheet of light paper, or vice versa,;and the laminated sheet thus formed convolutely wound to provide a body portion having walls in which the lamina- 1; tions are of alternating materials. It may sometimes be sufficient to interpose strips of a second material between the laminae of the container walls adjacent the ends. This may be done in the same manner as in forming the container from o a laminated sheet. In either instance, it is usually desirable to coat the upper surface or both surfaces of the interposed material with an adhesive in the manner prescribed for the construction first set forth. 45
The purpose of the use of adhesives and other interliners is to provide a laminated container body in which the end portions shall be substantially rigid, and in which portions the respective laminae shall be restricted in their relative movement, which in that portion ll of the body extending outwardly from the center point, the laminae shall be disposed in free frictional engagement to permit distortion of the container walls under manual pressure applied thereto. and
. thereby provide for the pressure discharge of the contents.
In Fig. 2, the blank or sheet l2, from which the container body is formed, is shown in perspective view and. in combination with an interliner sheet I2a. In this figure, the adhesive coatings on the sheet I2 are indicated by the same numerals as applied in Fig. 1, while corresponding adhesive coatings applied to the interliner sheet Ila are indicated as 1a, 8a, 9a, and "la, respectively.
In Fig. 3 is shown an alternate type of blank from which a' container body may be formed according to the present invention. The blank I 3 has a corrugated portion M which may be inteera] with the sheet, or may be applied by gluing. In this instance, greater strength is obtained for the container as a whole at only a small sacrifice of flexibility for the central portion ll of the container as shown in Fig. 1. By the use of an adhesive coating at 9 and H], a difference in relative rigidity and flexibility between end and center portions may be attained.
In Figs. 4 and 5, there have been illustrated the means whereby the center portion of a container according to this invention may be strengthened and its bellows action accelerated.
In Fig. 4 the conventional cylindrical container l is shown in perspective'with a section broken away to reveal a tubular insert I5 which provides a resilient and flexible supplementary support for the center portion. The insert l5 may be of rubber tubing as shown, or for economy may be of corrugated paper.
Fig. 5 illustrates an oval or obround container I6 such as is often used for talcum or dusting powders. The body portion has substantially the same characteristics as those of the containers illustrated in Fig. 1 or Fig. 4, but the auxiliary support for the center portion is a rectangular block of soft or spongy rubber ll of such size and so disposed within the container as to leave passageways 18 on either side of the block.
The dispensing container which has been thus described is filled, labeled and otherwise processed in much thesame manner as conventional containers of the same general nature. The present container, however, provides an integral arrangement for discharging a spray of dust or powder directly from the container by manual pressure applied to the center portion, without breakage or substantial permanent distortion of the container walls.
Various changes and alternative arrangements may be made within the scope of the appended claims, in which it is intended to claim all novelty inherent in the invention as broadly as the prior art permits.
