Roberts ABSTRACT: A bag support stand in combination with a bag holder having a pair of arms is disposed to engage and retain a grouping of self-opening plastic bags on these arms. The bags in their folded condition are slidably retained on the arms of the holder through apertures formed in-the sides and panels of the bags. In their folded condition, the bags hang so that their lowermost portion is further down from the arms than is the plane of the bottom of the bag in its open condition. The stand has a platform spaced a determined distance from the back support of the holder and the platform is spaced a determined distance from the rods so as to engage and support the bottom of the bag as it is filled with groceries and the like.
F3 Cu PATENTEU JAN 5197! INVEN'IUR. PATRICK J. PINTO AGENT 1 BAG SUPPORT sTAND cRoss REFERENCE TO RELATED APPLICATION BACKGROUND OF THE INVENTION 1. Field of the Invention The general field of art to which this invention pertains is in the class generally designated as Supports and more particularly to the subclass of bag holders.'Other subclasses of interest are holders with mouth-holdingframes"and those particularly with prong or hook-type.
2. Description of the Prior Art 1 The use of bag holders and chutes or guides to assist or maintain bags in an open conditionduringthe filling of the bag has been directed generally toward Kraft paper bags. .Supermarkets, grocery stores and the like, are constantly on the search for improved means for packaging, among which is the use of thin plastic bags for .packaging the customer's purchases. Such bags are shown in. US. Pat. No. 3,380,579 and are contemplated to be mounted on a bag holder shown in application Ser. No. 647,360. Thisgrouping of plastic bags is mounted on the holder adjacent the upright or back support member. From this grouping, each bag 'is opened one-at-atime for the loading or filling of the bag. Although other bag holders are known, they are generally for Kraft paper bags. Such a holder is shown in the Australian Pat. No. 270,432 as published Apr. 9, I964 with the actual inventor being 0. E. Franson. In this and other bag'holders, the horizontal support portions are on the same level whereby in this invention the open bag support portion is positioned above the horizontal support portion and nearer the rodsjof the holder.
In the use of plastic bags wherein apertures formed therein are used to retain the bags on the extending rodlike arms of the bag holder, the loading or filling of the bag causes theplastic around theholes to stretch and tear unless the bag is supported on its bottom. By supporting the bag on its bottom, one avoids undue strain and tearing of the bag from the extending arms. For this reason the bag support stand of this invention comprises a platform disposed at a determined distance from the pair of arms, said platform being closer to the arms than the horizontally extending portion defining the recess provided for the retaining and storing of the grouping of unopened plastic bags.
SUMMARY OF THE INVENTION The bag support stand of this invention is disposed to hold a bag holder as above-identified. This bag holder has a pair of arms extending at substantially right angles to a back support member. The bottom portion of the bag holder is adapted to be mounted to, or is made a part of,'the support stand of this invention wherein a channel or receiving groove is formed adjacent the back wall of the support stand. This groove is of a determined width sufficient to hold a substantial grouping of bags of determined quantity. Adjacent this groove and outwardly of the back support of the bag holder, there is provided a platform which is substantially parallel to the arms of the bag holder. This platform is disposed a determined distance below the arms of the holder so that after the plastic bag is caused'to be opened, the flat bottom of the bag is disposed to just sit or rest upon this platformand, as it is filled, to accept all of the load of the various items placed in the bag and to prevent a downward thrust or load being applied to the bag to cause the apertured portions of the bag to stretch or tear at the point of engagement of the apertures of the bat andthe bag holder support rods. The size and position of the supportplatform from the rods is a function of the bag in-its'open condition, these bags being, of course, the type commonly called'self-opening flat-bottom.
- BRIEF DESCRIPTION OF THE DRAWING The drawing represents an isometric view of the bag'support stand showing in relation to the stand and its platform a grouping of flat or unopened plastic bags and one opened plastic bag as it is retained upon the rods of the, bag holder and rests upon the platform.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawing wherein like members refer to like parts throughout, there is shown a bag support stand 10 which may be made of wood, metal .or plastic and which, as shown, includes a base or flat member 12 having-attached or extending therefrom and at right angles thereto a hack member 14. To the left or forwardly of this back member, there is provided a pair of spacers l6 and 17 of like height,
which spacers are attached to the base 12 by means not shown such as screws or the like. Carriedby these spacers and attached thereto is a platform member '20,which platform is spaced from the back member a determined distance to provide a channel or recess between the rightward edge of the platform and back member 14. The length and width of the platform 20 is selected to provide an adequate support for the open plastic bag to be hereinafter more fully described.
A grouping of plastic flexible bags which are like those to be used with this stand is described and claimed in my US. Pat. No. 3,380,579 issued Apr. 30, 1968. In this patent, as in the present application, the grouping of-bags is contemplated as being made of thin plastic and in astoredand mounted condition, the grouping of bags is disposed in'a flat position occupying a determined space. The grouping of unopened bags in the present drawing is indicated as 30and .is shown as carried by rods 34 and 36 of a bag holder such as described in my aboveidentified application Ser. No. 647,360. This opened bag 32 has gusseted sides 38 and 39 which, when expanded and opened, provide a square bag of known length and width and having a bottom portion which, when the bag is opened, is flat. This flat bottom rests upon the upper surface of the platform 20 and, with the bag in an opened condition, is supported by this platform while the clerk of the supermarket and the like fills the bag 32 with cans 40, and other items 42 and. Also shown in phantom outline is a backbrace 50 which may be attached to the back member 14 so as to position and carry the extending rods 34 and 36. The construction of the bag holder is more fully shown and described in the reference applicatIon.
USE AND OPERATION In use, the bag support stand 10 is sized to accommodate a particular class or size of plastic bags whereupon the platform 20 is a determined distance above the base '12 and has a determined length and width to' more than accommodate the bottom of the opened bag 32. The platform is spaced from back 14 so that the channel or recess provided between the platform 20 and back member 14 is disposed to accept a grouping of bags 30 such as fifty or one hundred. This grouping of bags is a determined packaging quantity asprovided by the supplier I of the plastic bags. The extending rods 34 and 36 are a determined distance abovethe surface of platform 20. The user of the bag support stand and bag support holder will likely have this assembled and attached or securely mounted to a checkout stand or the like and after installation, a grouping of plastic bags in a flat or unopened condition 30 is mounted upon the rods 34 and 36 and pushed to the back portion of the bag holder with the free end or the lowermost portion of the grouping of bags 30 dropping into the channel or groove immediately in front of back member l4'and behind platform 20.
The user of the bag support platform and holder in the steps of opening and filling the bag with groceries or the like grasps the outer bag and opens it and slides the bag forwardly on the rods until the flat bottom rests upon platform 20. As thus disposed, the open top of the bag is supported and extended between the two rods 34 and 36. The several items for packaging are placed within the bag with the load of those items placed therein being supported and carried by the platform 20 and with substantially no loud or strain upon the front or back walls and side gusscts 38 and 39 of the bag 32. After the bag has been filled to the desired height, it is slid from the platform and rods, after which it is carried by the customer or delivery boy. A plastic bag so packed has those items within the bag securely retained by the sidewalls of the bag and has in an unstretched and untorn condition those portions of the bag with apertures therein and with which the bags are carried by the holder. f
It is, of course, contemplated that the spacers l6 and 17 may be made removable so that they may also be made higher or shorter so that the platform 20 can be raised and lowered in respect to the location of rods 34 and 36. The platform in its support of the bag in its opened and unloaded condition is positioned to be just contiguous with the bottom so that when filled, no load is applied to the apertures of the sidewall and gussets of the bag.
it is further contemplated that the bags are made of a tough film such as polyethylene having a thickness of one to fourthousandths of an inch. The many advantages of using such a plastic bag, as contrasted to a paper bag, is not only for an improvement in the aesthetic appearance of the package but plastic also provides greater tear strength and, of course, a plastic bag is not effected by wetting. The contemplated bags are known as automatic self-opening, square-bottom bags. These bags are grouped by attaching together by welding and with the apertures in the bags aligned for ready mounting on the rods. Of course, the bags may be shipped in a loose condition.
In the above specifications and the claims to follow, the terms used in conjunction with the description of the bag and its construction are to be defined in accordance with Glossary of Packaging Terms providing for standard definitions of trade terms commonly used in packaging. The Glossary as a reference is the third edition compiled and published by the Packaging Institute, Inc, of 342 Madison Ave New York, NY. 10017 and copyrighted 1961.
The terms back, front, up, down, length and width and the like are applicable to the bag support stand as described in conjunction with the-drawing. These terms as used are merely for the purpose of description and do not necessarily apply to the position in which the various portions of the bag support stand may be constructed or used.
The conception of the bag platform is not limited to the example as shown but departure from this example may be made within the scope of the accompanying claims andprotection is sought to the broadest extent that the prior art allows.
