Description
YMN] J. w. CHALMERS WRAPPER FOR POWDER, GRANULAR, OR SIMILAR SUBSTANCESV .Filed July 3o, 1954 Patented May 19, 1936 UNITED STATES WRAPPER FOR POWDER, GRANULAR, OR SIMILAR SUBSTANOES John Walker Chalmers, Deptford, London, England Application July 30, 1934, Serial No. 737,665 In Great Britain August 1, 1933 2 Claims.
This invention is for improvements in wrappers for powder, granular or similar substances, for example, substances such as tea, and refers more particularly to a wrapper comprising a plurality of block ended wrappers contained within each other.
It is found that wrappers of the type referred to are usually open to the 'objection that the contents are liable to escape from the ends of the packets between the folds which are formed in order to form the packets, and it is an object of the present invention to provide a wrapper from which it is impossible for the contents to escape.
According to the present invention, there is pror vided a wrapper for powder, granular or similar substances wherein twol block ended containers are inserted one within the other, the inner wrapper being reinforced by the provision of a member or members secured to the side folds thereof, said side folds being further secured whereby the escape of the contents from the block end of the wrapper is prevented, and wherein the open ends of both containers are inter-folded and secured to completely seal the wrapper.
The invention will be more particularly described with reference to the accompanying drawing, in which:-
Figure 1 illustrates a blank arranged tol form the outer container for a wrapper constructed in accordance with the invention.
Figure 2 is a perspective View of the inner container folded and secured before insertion into the blank illustrated in Figure 1. v
Figure 3 is a perspective View showing the outer 35 container in position around the inner container with the open end of the wrapper partly closed.
Figure 4 is a perspective View showing a further stage in the closing of the wrapper.
Figure 5 is a perspective View of a completed wrapper formed in accordance with the invention.
Referring to the drawing, the inner container I is preferably formed as shown in Figure 2 before insertion into the outer container 2 and is folded about and secured to a reinforcing member 2a in 45 the manner described in copending application for Patent Serial No. 737,664, filed in my name concurrently herewith.
Thus the reinforcing member 2a which may comprise a cardboard strip is rst folded into a U 50 shape, and the wrapper is then folded into a U about the strip 2a so that the limbs of the U of the wrapper extend along the open sides of the U formed by the strip 2a. The narrow end folds of the wrapper comprising the material at the 55 base of the U are next folded inwardly against the sides of the strip 2a and are caused to adhere to the strip by adhesive. The side folds of the wrapper are then folded over and are both secured by adhesive to the strip 2a. The container when folded in this manner has the appearance illusl trated in Figure 2 in which the lines of adhesive 5 are clearly shown. As thus formed the inner container I is ready for insertion in the outer container 2.
Referring to Figure 1, the blank 2 is slit as shown at 3 and 4, and the portions 5 are arranged 10 to be folded beneath the side folds I Il and II when it is formed about the inner container I whilst the portions 6, I and 8 are arranged to comprise the closure flaps which close the open end of the wrapper opposite the block end thereof.
The blank 2 is folded about the inner container I so that it forms a U shape about the container I, and the portions 5 are then folded upwardly against the sides of the inner container, whereafter the side folds Il! are folded against the sides of the inner containers and the side folds II are folded upon the side folds I0 and caused to be secured thereto by means of lines of adhesive 9.
The side folds of the outer container and the side folds of the inner container are arranged one upon the other and after the outer container has been formed, as just described, the portions 6 and l, together with the upstanding portions of the reinforcing member 2a, and the portions of the inner container secured to the reinforcing member, are folded downwardly the one upon the other, as shown in Figure 3, this section causing the portions I2 of the container I to be fold- 35 ed into substantially triangular portions I3 and I3a, as seen in Figure 3. The flaps 8 and 8a, together with the triangular portions I3 and I3 are then folded outwardly from the packet as shown in Figure 3, and a line of adhesive I4 is 40 applied to the exposed folds or closure flaps of the wrapper, as shown in Figure 3.
Referring to Figure 3, it will be seen that the line of adhesive I4 extends along the whole length of the flap 8, and down the two free sides thereof, and also continues as a continuous line over the corner portions I5 of the triangular portion I3 and across the folded flaps 6 and l, and the small corner portions I6 of the flap I3a and eX- tends slightly over onto the remaining closure flap 8a.
When the adhesive has been applied in the manner just described, the flaps 8d and I3al are folded over into engagement with the naps 6 and 55 1, and are secured thereto by means of the adhesive lines I4, the innermost corners of the closure folds being secured by the adhesive at the point I6. The remaining flaps 8 and I3 are then folded downwardly into engagement with the flap 8a and are secured thereto and also to the flaps 6 and 'I by means of the adhesive lines I 4. In this case also the corners of the folded aps are secured by the provision of the adhesive at the points I5. In this manner it will be seen that a wrapper is provided from which it is impossible for the contents to escape, since the inner container is sealed atrthe block end at every point at which the contents mightV escape, whilst by interfolding the inner and outer containers and securing them in the manner described, the open end of the wrapper is also secured against the escape of the contents and the contents are Y therefore, securely held within the wrapper until ner container, a reinforcing element for each of two opposed sides of the inner container, an outer block-ended container, two closure aps arranged on opposed sides of the wrapper, each of said closure flaps being constituted by a part of the inner container and a part of the outer container, and folded one upon the other to engage with the contents of the wrapper, a line Aof adhesive applied to the outer surface of each of the two flaps and disposed adjacent the line Y about which each flap is folded, two further closure flaps arranged on the other opposed sides of the wrapper and constituted by a part of the inner container and a part of the outer container, and lines of adhesive applied to the innerV surfaces of said further closure aps and disposed adjacent the edges thereof.
2. A rectangular wrapper as claimed in claim 1 in which two opposed closure aps are further constituted in part by the free ends of the reinforcing elements.
