Fig. 11 is a sectional elevation showing the tube terminal after engagement with the panel;

Fig. 12 is a sectional elevation of another modified form; and

Fig. 13 is a plan view of the inner container of the form illustrated in Fig. 12.

Referring to the drawings in detail and first of all to the form shown in Figs. 1 to 6, inclusive: 2 designates a radio tube which may be the usual metal or glass tube having contact terminals 4 at one end thereof.

In assembling the tube 2 is first inserted in the inner wrapper or container shown in Fig. 5. This-wrapper comprises side wall 6 having projecting side flaps 8 and (0, end walls or panels 12' and 14. The end panel 12 is provided with end flap 16 and side flaps 18 and 20. The end panel 14 is provided with side flaps 22 and 24. The end panel 14 also has an end extension 26 which is extended to form a tube-supporting member 28. The tube-supporting member 28 is provided with side flaps 30, 32 and an end flap 34. The tube-supporting member 28 is also provided with central opening 36 for the reception of the tube 2 as seen in Fig. 3. The end panel f 2 is provided with an opening 38 for the terminals 4 of the tube 2. One edge 40 of this opening is straight so as to prevent rotation of the tube therein when the tube and receptacle are assembled as seen in Fig. 2.

The blank illustrated in Fig. 5 is folded to form a wrapper for the tube. The flaps 30, 32 and 34 of the tube supporting end wall or panel 28 are folded upwardly at right angles to this panel along their respective fold lines 31, 33 and 35. The panel 28 is then folded upwardly along fold line 62 and extension 26 folded upwardly along fold line 54. The flaps 22 and 24 of the end panel 14 are folded downwardly in the opposite direction to the flaps 30, 32 and 34 at right angles to this panel and this panel is then folded upwardly along fold line 52 to a position at right angles to the side wall 6 with the panel 28 intermediate the panels 14 and 12. The side flaps 8 and (0 of the side wall 6 are then folded upwardly along their fold lines 42 and 44, respectively, at right angles to the side wall 6. The end panel 12 is then folded upwardly along the fold line 13 at right angles to the side wall 6 and

BO

2,365,664 the flaps 16, 18 and 20 of the end panel 12 are folded upwardly at right angles to this panel along the fold lines 43.

The inner container thus folded is in tubecontaining position, as illustrated in Figs. 3 and 4. The tube is inserted during the folding operation in the following manner: The top end of the tube, that is, the end remote from the terminals 4, is first inserted in the orifice 36 of the end panel 28 from the underneath side as shown in Fig. 5 whereby the tube is at right angles to the plane of the blank. As the panel 28 is folded as above described the tube will be turned therewith until the panel is intermediate the panels 14 and 12 and is at right angles to the side wall 6 and the tube superimposed and in parallel relation thereto, as shown in Figs. 3 and 4. The side flaps 8 and 10 are then folded upwardly to vertical position. When the tube is in the wrapper in the position just described the end panel 12 is then folded upwardly and at the same time the tube may be rotated to bring the terminals 4 into proper register with the orifice 38 in the panel 12 whereupon the panel may be brought against the base of the tube with the terminals extending through the opening 38 and with the flaps 16, 18 and 20 folded at right angles to the panel 12.

If desired an assembling form for the inner wrapper may be provided whereby to retain the side flaps 8 and 10 and the end panel 14 upright during the final folding of the wrapper and insertion of the tube therein as aforesaid. Such assembling form may comprise parallel side walls and a spaced end wall formed of suitable rigid material.

The inner wrapper above described with the tube in position therein is inserted in the outer wrapper or container with the terminal end of the tube uppermost, as shown in Fig. 2 and with 40 the side wall 6 constituting the front side wall of the wrapper.

The outer container, as illustrated in Fig. 6, comprises front wall 70, side walls 72 and 74 and rear wall 76.

The rear wall 76 is provided along one side with a glue flap 80. The side walls 72 and 74 and the glue flap 80 are provided with weakened lines 90, which may be cut through for their full width or for part of their width or may be perforated, if desired. The weakened line 90 in the glue flap 80, however, is preferably cut through to provide an extension 82. The sections or extensions of the side walls 72 and 74 above the line 90 designated 88 and 84, respectively, eventually are to constitute side walls of a cover for the outer container. The front wall 70 is provided with an arcuate incision 110 to provide an extension 86 of the front wall which extension eventually is to constitute the · front wall of the cover. The rear wall 76 has an extension 78 which eventually is to constitute the rear wall of the cover. This wall has a score line 91 which constitutes the hinge for the cover.

The extension 88 of the side wall 72 is provided with an end flap 94 having a perforation '92 whereby the flap 94 may be severed and removed. This removable section may be provided with space for the dealer’s record, as shown in Fig. 1, which section may be removed and retained by the dealer after the sale of the tube. **

The extension 78 of the back wall 76 is provided with a flap 96 constituting an end wall and in turn having a flap or lip 98 secured thereto. The extension 84 of the side wall 74 is pro vided with an end flap 100. This blank has no flaps at its lower end inasmuch as this end of the outer container is to remain open.

The outer container is formed from, the blank 5 shown in Fig. 6 by folding the blank along the vertical fold lines 102, 104, 106 and 108 and securing the glue flap 88 to the inner face of the side wall 72 and securing the extension 82 to the inner face of said extension 88 by adhesive or 10 any other suitable fastening means. When the blank is thus folded and its top flaps folded inwardly, it will be in the form illustrated in Fig. 1 and as will be seen the side walls 72 and 74 are either cut through as shown at 80 or weakened 15 along these lines, and the front wall is provided with an arcuate cut 110 which forms a lip 113 for the cover Of the outer container.

Short slits 109, as shown in Figs. 1 and 2, may be provided in the lower corners of the front 20 wall 86 of the cover to provide for additional flexing of the lip 113 and facilitate closing the cover as the same passes over the shoulder formed by the inner container and which projects above the incision I f 0.

If desired short slits iOl may be provided in the lower end of each of the fold lines 102, 104, 106 and 108 of the blank of Fig. 6 whereby to facilitate insertion of the inner wrapper within the outer container, as will be appreciated.

Slits 4i may also be provided in the terminal orifices 38 of the panels 12 to facilitate insertion of the tube terminals therein and to cooperate with the flattened or straight edge 40 of the orifices In maintaining the tube against 35 rotation.

When the inner wrapper containing the tube is inserted in the outer container the flaps 94 and ί 00 of the container are folded over the top of the container and the flap 96, which is integral with the rear wall of the container, is folded over these flaps and its lip 98 tucked behind the front wall 86 of the cover. When the parts are thus assembled it will be seen that the flaps 22 and 24 of the end panel 14 of the inner wrapper project outwardly as clearly seen in Fig. 3 and these are secured to the side walls of the outer container, for instance to the side walls 72 and 74, by means of eyelets 112 or by grommets, staples or adhesive, as may be desired.

The tube is now securely held in place in the inner container and the inner container is in turn held in place in the outer container.

When it is desired to test the tube it is merely necessary to rupture the weakened lines 90, then fold back the cover as shown in Fig. 2 and insert the terminals in the testing device. If the tube is found satisfactory the dealer removes the tab 94, enters the desired data upon it and retains the tab. If, however, the tube is defective, it is merely necessary for the dealer to fold the cover back in place and return the tube to the manufacturer without rupturing or mutiliating the container.

, Referring now to the form illustrated in Figs. 8 to 11, inclusive, which form of receptacle is adapted to accommodate a double contact tube 120, that is, a tube having contact terminals 4 at one end and a contact terminal 122 at the other end. In testing tubes of this character it is necessary to insert the terminals in the testing device and apply a lead to the contact member

122 at the other end of the tube. Accordingly it is necessary that both the terminals 4 and the contact member 122 be exposed for testing. In my improved construction it will be appreciated

164 3 engages the flat end of the tube 2 so that when the contact terminals 4 are inserted in the orifice or central opening 38 in the opposite end wall 12 the tube is securely held between these, end walls or panels.

Referring now to the assembling, apparatus illustrated in Fig. 7. This apparatus comprises a base 200 having an upstanding rear wall 202 with forwardly projecting arms 204. The base member 200 is provided with a block 206 located directly below the space between the arms 204. This block is provided with a hole or socket 200 of a diameter sufficient to accommodate the terminals of the tubes. In using the apparatus illustrated in Fig. 7 the outer container is inserted over the block with the flaps 94, 96 and 100 opened and lying flat upon the base member 200, as illustrated in Fig. 7, and the outer container engaged between the arms 204. With the outer container in this position the inner wrapper is pushed down through the bottom of the outer container which in the assembling apparatus is uppermost, and forced downwardly therein until the terminals of the tube enter the socket 200 and the end panel 12 of the inner wrapper engages the upper surface of the block 206. Due to the close fit of the wrapper within the container the advantage of the slits 101 in the bottom corners of the container will be apparent in the beginning of the. insertion of the wrapper therein. It will be appreciated that when the inner wrapper engages the block the same is properly located in the outer container. The flaps 22 and 24 of the inner wrapper as will be appreciated are in engagement with the side walls of the outer container so that the rivets or eyelets Hl may be applied to secure the inner wrapper within the outer container.

An extension may be provided on the base 200 of the assembling apparatus of Fig. 7 to accommodate the assembly form for the inner wrapper hereinbefore mentioned. This extension may be provided with two side walls and a spaced end wall. The inner wrapper conveniently can be placed within these walls with the side flaps 8 and 10 in engagement with the side walls and held in an upright position thereby during the insertion of the tube in the inner wrapper as hereinbefore mentioned.

After the inner wrapper is secured to the container by the eyelets 112 as above mentioned, the receptacle may be removed from the assembled device and the flaps folded as previously described to close the outer container.

It will be appreciated that the central opening 38 in the end wall 12 may be made of various dimensions to accommodate various types of tubes, the opening 38 being such as to engage the wall of the tube to prevent relative lateral movement of the tube within the receptacle.

It will be appreciated also that the edges of the flaps 18 and 20 of the inner wrapper will engage the inside of the walls of the outer container and the top edge of the side walls 8 and 10 will engage the panel 12 when the wrapper is in place in the container whereby to maintain the panel 12 parallel and at right angles to the side walls of the outer container at all times. Likewise the panels 14 and 28 are maintained 70 parallel and at right angles to the side walls of the container by reason of their respective flaps and by reason of the flaps 22 and 24 being fastened to the side walls by the-eyelets 112.

It is to be understood that various changes and modifications may be made in the struc2,265,( from the following description that neither the terminals 4 nor the contact member 122 is exposed until the tube is ready to be tested. The outer container of this form of my invention may be similar to the form illustrated in Figs. 1, 2 5 and 6. The inner wrapper of Fig. 8 likewise may be similar to the inner wrapper of Fig. 5 except that the wall 14' is provided with incisions 150, 152 and 154. These incisions may, if desired, be perforations. Hie incisions are situated about 10 the center of the end wall 14' adjacent the contact (22 of the tube. When testing the tube shown in the receptacle of Fig. 8 the cover of the same is opened, as in the form illustrated in Figs. 1 and 2, to expose the terminals 4 for test- 15 ing. To expose contact member 122, however, it is merely necessary to press with the fingers on either side of the incisions 150 and 152. It will be appreciated that this pressure on the end wall will cause the contact 122 to engage the end 20 panel 14' between the incisions and thereby rupture the same whereupon the flap or tab 124 thus formed may be raised to the dotted line position shown in Fig. 11 to expose the terminal 122 whereby the lead may be attached to this ter- 25 minal or contact for the purpose of testing.

If desired instead of providing incisions 150, 152 and (54 for the tab 124 the three edges of · this tab may be cut through completely on its three sides without any connecting parts where- 80 by when pressure is applied the tab will engage the contact 122, as above mentioned, whereupon the flap may be raised as aforesaid. If the tube is found, on testing, to be defective it is merely necessary to push the tab 124 back in place, as will be appreciated.

The form of tube illustrated in Fig. 8 is provided with a shoulder which, as will be seen from the drawing, engages the intermediate panel 28. The tube being held in the orifice of the panel 28 relative lateral movement of the tube is prevented and in addition by reason of the shoulder of the tube engaging the panel 28 the tube is supported and held against longitudinal movement when applying pressure to insert the ⁴⁸tube in the testing block and when applying pressure to raise the tab 124 of the end panel 14’.

It will be appreciated that due to the fact that the inner wrapper in both the forms thus far described projects slightly above the weakened lines 90 a shoulder is provided by the inner wrapper for engaging by the lip 112 in closing the device. This shoulder will also function frictionally to retain the cover closed after the weakened lines 90 have been ruptured.

Should the space on the testing block be limited whereby when the cover is folded back, as shown in Fig. 2, it would interfere with the insertion of the terminals 4 in the socket of the testing block, or if for any other reason the ⁰⁰cover would interfere with the testing of the tube the same can be collapsed and folded back against the rear wall of the container, as shown in Fig. 10. The collapsing of the cover is accomplished by withdrawing the flap 98, raising the °® flaps 96, 94 and 100, then folding the side walls against each other and finally folding the folded walls against the rear wall 76 of the outer container, as shown in the drawing, whereby the same is entirely out of the way.

Referring now to the form illustrated in Figs. 12 and 13 wherein a different type tube is enclosed. It will be seen that the tube-supporting wall 28 is eliminated. The end wall 14 of Fig.

2,266,664 tures herein illustrated and described without departing from the spirit and scope of my invention.
