Description

July 4, 1950 H. LOMBARD SEALED RECEPTACLE Filed Aug. 21, 1946 Patented July 4, 1950 UNITED STATES PATENT OFFICE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 9 Claims.

This invention relates, in general, to bags or receptacles constructed of fabric or fabric composition, and deals, more particularly, with an improved construction for a receptacle of this character including means for tightly sealing the receptacle but capable of being easily and quickly opened to expose the contents of the receptacle in a minimum of time and effort.

The invention is particularly suited for use as a pack or bag for dye marker material carried as rescue equipment by persons traveling over water and used in emergencies for coloring an area of water to provide a signal which will attract the attention of rescue aircraft. While the invention is particularly suited for this purpose, it is not limited to such use inasmuch as the improved construction of the bag or receptacle is one of general utility and mayreadily be adapted for use in a wide range and variety of applications.

In general, dye marker packs comprise a bag portion which is easily and quickly opened together with a tape for attaching the bag to a life vest. The construction of the dye marker pack heretofore used has been objectionable in that it fails to withstand satisfactorily ordinary handling and usage and all too often breaks open when not intended or desired, particularly along the seam of adhesive adjacent to the pull tab. This is due to the fact that in previous dye marker packs, the pull tab and adjacent seam of adhesive are exposed, and under ordinary handling and usage, there is necessarily a frequent, rubbing, pushing or pulling effect on the tab which gradually causes the adjacent seam of adhesive to work'open and permit escape of the dye marker substance from the pack. Considerable trouble and difficulty thereby result by reason of the fact that the dye marker substance is highly injurious to the skin and readily causes stains and discoloration of clothing and any other gear it contacts.

A primary object of the invention, therefore, is to provide a dye marker pack which overcomes the foregoing deficiencies and which may be easily manufactured, at relatively low cost, from a single piece of material to provide a strong, durable receptacle that may be tightl sealed and yet is capable of being opened readily whenever desired.

A further object of the invention is to provide a. dye marker pack of this character comprising a pull tab for opening'the bag, together with a cover flap protecting the pull tab against wear and handling which would tend to 1095611 the D1111 tab and cause an undesired or unintended opening of the pack. At the same time, the pull tab is readily accessible at all times simply by lifting the cover flap and may be easily and quickly actuated to break open the pack when desired in the most expeditious manner.

Another object of the invention is to provide a receptacle having the foregoing features of construction together with an improved reinforcing arrangement for securing the attaching tape thereto in a manner which withstands the most severe conditions of constant usage and handling.

With such objects in view, as well as other advantages which may be incident to the use of the improvements, the invention consists of the parts and combinations thereof hereinafter set forth and claimed with the understanding that the several necessary elements constituting the same may be varied in proportion and arrangement without departing from the nature and scope of the invention as defined in the appended claims:

In order to make the invention more clearly understood there are shown in the accompanying drawing, means for carrying the invention into practical effect without limiting the improvements in their useful application to the particular construction and arrangement which, for purpose of explanation, have been made the subject of illustration.

In the accompanying drawings:

Figure 1 is a front elevational view of the improved receptacle;

Figure 2 is a fragmentary perspective of the receptacle showing the general construction thereof;

Figure 3 shows the improved receptacle as worn on a life vest and illustrating the method of opening the pack; and,

Figure 4 is an enlarged sectional view of the receptacle showing the details of construction thereof.

Referring now, more particularly to the drawings, the improved receptacle I0 is best seen in Figures 2 and 4 as constructed preferably from a single piece of fabric which is folded intermediate its ends at H to define the front 20 and back 30 of the pack. The longitudinal edge portions of the pack are secured together by striplike areas of adhesive l5, Figure 1, and along the lower fold at I 6 if desired for added strength.

The opening at the top of the pocket defined by the front'and back portions 20, 30, respectively, is sealed by a film of adhesive 33. The front 20 of the package has its free end folded adjacent 3 the top of the pocket thus provided to define a pull 2i and a portion of this pull tab is further secured by reinforcing adhesive 36 to the underside of a cover flap 3i extending from the back 35).

The back 38 of the pack extends upwardly to the top of the pack and is folded to provide a double layer of material 35. The extremity of the top layer of this doublelayer of fabric 35 extends free to provide the flap 3| overlying the pull tab 2! at the top of the pack.

The double layer of material 35, at the top of the pack preferably is designed of such length as to provide a return foldedportion 36 for accommodating an attaching tape 46 which is secured to the pack as by rivets ll, or stitching-or equivalent means.

In manufacture, it will be understood, that the dye marker substance 9r other contents of the pack are inserted within the pocket defined by the adhesivel secured front and backportions 20,35, respectively, whereupon the film of adhesive 33 is applied to seal the opening of the pack and the adhesive 34 adjacent the top of the pack applied to secure the under face of the rear portion of flap M to the upper face of the pull tab M, with the free end portion of the flap 3i overlying the free end of pull tab 2|. In mass production methods of assembly, the bags are thus prepared with their contents, whereupon the attachrnent of the tape 40 under the folded portion 36 is easily effected by rivets,.stitching or the like.

'As illustrated in Figure :3, for example, with the pack attached to a life vest by the tape 49, the wearer has little difiiculty in grasping the pull tab?! in one hand and the cover flap 3! in the other hand, and upon pulling the same apart, the pack separates in the area of the reins forcing adhesive 34, then at 33, and then in the areas i along the sides of the bag in a manner whereby the contents of the pack are easily and quickly freed therefrom.

It will be appreciated that in the construction ofthe bag or receptacle of the present invention, thecover flap 3i overlies the pull tab 2| and thereby shields the pull tab 2| at all times against any rubbing, pushing or pulling effect which could be effective past the film of protective adhesive 3G to cause the pull tab 2] to separate from the sealing adhesive 33 and permit an undesired or unintended opening of the pack.

It will also be appreciated that the arrangement whereby the bag may be made of a single piece of fabric provides astrong and durable construction which may be manufactured at rela-. tively low cost.

A further advantage resides in theconstruction comprising the double layer-of fabric 35 including the folded portion 35 for attaching the tape in a manner which is adapted to withstand any force that might tend to tear the tape from the pack in the normal use thereof.

The invention has been described in connection with its use as a receptacle for dye marker packs, and the like, but it will be quite apparent that it has equal utility in various other applications and uses.

'It will be understood that the foregoing description and accompanying drawings comprehend only the general'and preferredembodiment of the invention, and that various changes in the con struction, proportion, arrangement and general combination may be made without departing from the spirit and scope of the invention. The present embodiment is therefore to'be considered in 4 all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, with all changes falling within the scope, meaning and range of equivalency of the claims intended to be embraced therein.

7 The-invention described'herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
