CONTAINER A Filed Nov. 30, 1935 CFI Patented Dec. 12, 1939 UNITED sTATEs PATENT OFFICE CONTAINER.
'Edouard Louis Diot, Neuilly-sur-Seine, France Application November 30, 1935, Serial No. 52,436
In France November 30, 1934 3 Claims.
The present invention relates to containers and method of making the same.
The present invention provides a. method of making a cylindrical container of a curvilinear or polygonal cross-section which consists in Capping the free end of a cylindrical mandrel of a corresponding cross-section with an element intended to form the bottom of the said container; this element comprises a bottom and a skirt anged perpendicularly to the said bottom over the Whole periphery thereof; on this flanged skirt is fixed the free end of a strip of flexible material intended to form the side wall of the container, then the said strip is Wound round the said mandrel in overlapping convolutions for the length desired, the successive convolutions being secured to each other; vat least, the container thus obtained is removed from the mandrel.
At one of the ends, at least of the longitudinal Wall of the container, 'convolutions of the strip have a pitch which is nil or very small so as to commence and finish the side Wall of the container in a plane perpendicular to its axis. This wall may at the same time be reinforced in these parts by an additional winding of the strip with no pitch over any desired number of the convolutions.
By reason of the fact that the container to be obtained is of a curvilinear or polygonal crosssection, that is to say cylindrical or prismatic and' not of longitudinal contoured section, the strip used for the formation of the side Wall of the container may be formed not only by a strip or band of material corrugated or creped transversely, like that mentioned in my patent application Serial No. 909, but even by a strip of smooth material.
.The employment of a strip or band of corrugated or creped material has the advantage of giving a special strength elasticity tothe side Wall of the container, properties which are very advantageous in many cases; furthermore, this l creped or corrugated material gives an outer wall yhaving roughnesses which, although very slight,
are also of importance in many cases.
As in the case of the shaped articles and containers of the aforesaid patent application, the
fixing of the strip or band on the cylindrical edge- The container obtained in the manner above described is drawn off the mandrel, if required after drying for the desired length of time, and may be used in any desired manner.
If required, it may be provided with a cover, 5 which may be either fitted inside the upper part of the container, or tted externally over this upper part. This cover may be fixed and sealed on the container when the latter is filled with its contents. In cases where the open end of the l0 container comprises a reinforced part, the more or less accentuated external shoulder' formed by the reinforcement at this end may be utilised for fixing or sealing the cover.
The method above defined enables containers l5 of any transverse cross-section to be obtained, and consequently not only containers of circular cross-section, but also containers of any curved cross-section, such as oval, elliptical etc. as well as containers of polygonal, decagonal, octagonal, hexagonal, pentagonal, rectangular, square or like cross-section. The containers thus obtained may be provided inside or outside, or both inside and outside, with a coating suitable for their use, for instance, with an impermeable coating. Such a coating may, for example, be formed by means of a lm of paraiiin wax.
Similarly containers similar to those above described, may be made translucent ortransparent by making them by means of a strip or ribbon of translucent or transparent material.
It will be understood that the present invention includes, also, as new products, the containers re'- f sulting from the application of the method above defined, also the means used for its applications, and in this connection it is necessary to mention that it also includes the empty containers obtained as Well as the same containers filled with various substances, solid or liquid and the said filled containers may be sealed or otherwise. The 40 invention is particularly applicable to containers for edible liquid foods, beverages, such as milk, oil, etc. and pharmaceutical products.
The invention is more particularly described with reference to the accompanying drawing in which:
Figure 1 is a diametrical section of a bottom intended for making a container like those above dened.
Figure 2 is a front view of the said bottom.
Figure 3 shows in diametrical section a container obtained with the aid. of the above mentioned bottom.
Figure 4 is an elevation-of the same container. 55
Figure 5 is an elevation of the end oi a mandrel for forming the said container.
Figure 6 is also an elevation of the en'd of another mandrel for forming a container in accordance with the invention.
Figure '7 is a diametrical section of a container made with the aid of this latter mandrel.
Figure 8 is an elevation of the`container shown in Figure "1.
In these various gures the same reference numerals denote the ,same parts.
In Figures 1 and 2, a container bottom is shown which is formed of a bottom piece I and provided with a iianged edge 2. This bottom may have been obtained, for exampe, by stamping or pressing from a cardboard blank. This bottom is placed on the end of a cylindrical mandrel; a strip or ribbon is fixed to the flanged edge 2, wound upon the latter, then the winding is contlnued in a helix until all the mandrel is covered. The winding may be commenced by one or several convolutions wound one upon'the other, forming an additional thickness 3, followed by normal convolutions 4, and terminated by one or more convolutions wound one upon the other, forming a reinforcement 5 at the end of the container. The xing of the strip to the edge 2 of the bottom, and also the joining of the convolutions together, are effected by glueing, for instance, durlng the course of the winding itself, the strip used being for this purpose provided with glue or any other adhesive on that part of the width oi' that face which covers the preceding convolution.
When the Winding of the strip is iinished, this strip is cut; the shaped article obtained is withdrawn from the mandrel, if necessary, after a suiilcient drying. 'Ihe piece obtained is of the form shown in Figure 4. Figure 5 shows that this piec'e has been obtained-by mounting the bottom i on the end 6 of a mandrel 1, this end of the mandrel being oi' a diameter slightly less than that of the main body of the mandrel, so that once the bottom I-2 is put in position on the mandrel, theexternal face of its edge 2 is iiush with the cylindrical face of the part 1.
It will be understood that the invention is not limited to this mode of operation, and Figure 6 shows a mandrel 1 of uniform diameter up to its en d on which a bottom I-2 is mounted. In this case, as is shown in Figures '7 and 8, a slight shoulder 8 is formed, without it being necessary to make an additional thickness at the start oi the winding.
When the article to be made is to have other than a circularsection, the bottom |-2 and the mandrel have shapes corresponding to that to be obtained.
In the accompanying drawing, it has been supposed that the amount lR=Ll (L being the width o f the strip, l the spacing of the convolutions, and R the overlap) by which the convolutions overlap. each other, is about half the width of the strip, but of course there is nothing denite about this; the value R. of the ovei'- lap may always be adapted to the special conditions in each particular case. Thus, for example, when the side wall has to be very strong,
a large overlap is necessary, since it has the 5 double advantage of giving a wall of a stronger thickness with convolutions secured together on a greater width of strip. When, on the other hand, the wall is to be very thin, .the overlap R is reduced to a minimum. It is then of im 10 portance to take care, for instance by using an adhesive oi superior quality, to eiect a sui'- ficient connecting of the successive convolutions.
What I claim is:
l. A container provided with a large open end 'il-,5
having a bottom cap and a body made solely from a strip oi creped material the inner end l of which is xed on the outer side of the lateral wall of said bottom cap by at least one convolution the pitch of which is nil, said strip being 20 then wound in helical convolutions to form said body, the outer end of said strip being wound in' at least one convolution the pitch of which is nil to form a reinforcement at the opposite end of said body, each convolution of said strip be- 25 ing cemented to the previous one and an impermeable coating on one at least of the inner and outer faces of said container.
2. A paper container provided with a large open end having a bottom cap and a body made 30 solely from a strip of paper, said paper strip having transverse corrugations that have substantially the same value throughout the width of the strip and having its inner end fixed on the outer side of the lateral wall of said bottom cap 35 in at least one convolution the pitch of which is nil, said strip being then woundin helical convolutions to form the body of said container, the outer end of said strip being Wound in at least one convolutioh the pitch of which is nil 40 i stantially the same value throughout the width 50 of the strip and having the inner end fixed on the vlateral wall of said bottom cap by at least one convolution the pitch of which said strip being then wound in helical convolutions along a surface the generatrices of which are ar- 55 rangedalong extensions of the generatrices of the inner side of the lateral wall of the bottom cap to form the body of the container, the outer end of said strip being wound in at least one convolution the pitch of which is nil to ferm 60 a reinforcement at the opposite end of said container and each convolution of said strip being cemented to the previous one.
