Definitions

  • the present invention relates to carrying handles and more particularly to handles for sealing and carrying thermoplastic bags.
  • Handles for bags designed for carrying products or articles are well known. Certain paper bags are pro­vided with cardboard reinforcing handles secured to the paper bag by gluing or stapling. Larger paper bags are often provided with loop type carrying handles secured to reinforced areas of the paper bag by gluing or stapling.
  • thermoplastic bags are usually too thin or are otherwise unsuitable for the attachment of handles by gluing or stapling.
  • Such thermoplastic bags are typic­ally provided with handles of several layers of the bag material heat welded to form a reinforced handle section or are provided with loop type handle sections much thicker than the bag material.
  • Such handles are typic­ally manufactured of a compatible thermoplastic material and attached to the bag opening by heat welding. Such handles often provide for sealing of the bag opening through frictional engagement of pins or posts on one section of the handle assembly with holes or recesses in the complementary section of the handle assembly.
  • a carrier bag For example, insulated bags that carry hot or cold products, such as food and drink, need to be sufficiently strong so as not to tear or open while maintaining the appropriate seal on the bag to achieve the insulation effect. Handles for such a carrier bag must be sufficiently strong to support the weight contained in the bag. The handle must also be capable if remaining in a closed position so that the carrier bag is sealed while being carried and does not tear open.
  • a bag handle closure device comprising a pair of opposing handle strips adapted to be attached to a bag or the like, at least one of said handle strips having a handle loop, releasable connecting means on said handle strips above the lower edge portions of said strips to connect said handle strips releasably together in substantially parallel relationship, characterised in that interlocking means are provided on the lower portion of each of said handle strips for retaining said handle strips together at said lower portion thereby to hold the strips against opening apart when they are adjacent to each other with the interlocking means engaged.
  • a carrier bag handle closure embodying the inven­tion can effectively maintain a carrier bag in a closed condition even when relatively heavy or bulky items are carried in the carrier bag. Furthermore, the bag closure can be easy to open and close when required and be econo­mic to manufacture.
  • the releasable connecting means comprises an outer closure member on one handle strip and an inner closure member on the other handle strip, the inner and outer closure members coacting in a complementary snap-on engagement when the handle strips are connected together.
  • both the outer and inner closure members and the interlocking means on the carrier bag handle provides a tight, double lock seal to keep the bag handle in a closed position even if the relatively heavy weight, such as 50 lbs., is within the carrier bag. Even when the outer closure member and the inner closure member are not in a snap-on engagement, the interlocking means still prevents the closure bag from opening.
  • the carrier bag opens only when the double lock is open, namely both the snap-on engagement of the inner and outer closure members and the interlocking means.
  • the bag handle closures of the present invention are described as fixed to thermoplastic bags, but they could easily be adaptable to other types of bags.
  • the bag closure of Figures 1 and 2 comprises a pair of opposing or complementary handle portions or strips 10 and 20.
  • the handle portions 10 and 20 are pre­ferably of a thermoplastic material suitable for attach­ ment to the bag 30, shown in phantom, by heat welding.
  • Each handle portion 10, 20 preferably has formed along its top edge 10a and 20a, respectively, a handle loop 12 and 22. However, only one of the handle portions 10, 20 may have a handle loop in some cases.
  • pins 14 Extending from handle portion or strip 10 are pins 14, preferably adjacent the handle loop 12.
  • holes 24 On handle portion 20 adjacent the handle 22 corresponding to pins 14 of strip 10 are holes 24.
  • Each hole 24 is slightly smaller in diameter or size than each pin 14 so that when strip 10 is oriented adjacent to strip 20, pins 14 frictionally engage holes 24 to releasably maintain the strips 10 and 20 in a bag closed position ( Figure 2).
  • Other suitable gripping means preferably of snap-­engagement type either on the handle strips 10, 20 or the handle loops 12, 22 may be used.
  • notch-forming elements 16 Extending from the bottom edge 10b of strip 10 are one or more notch-forming elements 16.
  • the notch-­forming elements 16 preferably are formed from end sections 16a extending substantially perpendicular to strip 10 and a crossbar 16b interconnecting the end sect­ions 16a so as to form an opening or slot 10c adjacent strip 10.
  • Each tab 26 extends from the bottom edge 20b of handle portion 22 ( Figure 1). Tabs 26 correspond in number and orientation with respect to the position and number of the notch-forming members 16 such that tabs 26 can slide into the openings or slots 10c prior to engagement of holes 24 by pins 14.
  • the handle closure is preferably used in combination with a bag made of relatively thin polyethylene material.
  • Handle strips 10 and 20 are also preferably polyethylene and are heat welded to the bag.
  • tabs 26 of strip 20 are aligned above the elements 16 of strip 10 and then are slid down­ wardly into the slots 10c.
  • the upper part of the handle portions 10 and 20 are at least slightly separated from each other at the time the tabs 26 are being seated in the slots 10c, so that the pins 14 do not enter the holes 24.
  • the pins 14 are still not in the holes 24 until the pins 14 are frictionally forced into holes 24 by the user squeezing the handle portions 10, 20 towards each other, thereby sealing the bag opening ( Figure 2) and providing a convenient carrying handle H.
  • the positioning of tabs 26 in slots 10c provides a closure resistant to inadvertent release of pins 14 from holes 24 which might otherwise cause separation of the bag mat­erial due to heavy or bulky items in the bag.
  • the user When it is desired to re-open the bag, the user simply pulls the handle portions 10 and 20 apart, usually by pulling on the handle loops 12, 22, which initially releases the handle portions 10, 20 laterally away from each other with a slight lifting movement, the tabs 26 are easily lifted out of the slots 10c and the bag is fully opened ( Figure 1).
  • notch-forming members 16 may be formed in other shapes and configurations so long as it is adapted to receive and interlock with some lower portion of the opposite handle portion.
  • the carrier bag handle 110 has a pair of opposing handle strips 112 and 114 capable of being attached to a carrier bag 111. At least one of the handle strips 112 and 114 has a handle loop 116.
  • the handle strips 112 and 114 are made of a thermoplastic or thermoset material that provides the requisite strength to the bag handle.
  • the thermoplastic or thermoset material such as polyethylene
  • other materials for the handle strips 112 and 114 and other methods of attaching these strips to the carrier bag can be used within the scope of the invention.
  • both handle strips 112 and 114 have a handle loop 116 that is of the size and shape to accommodate the hand of the person carrying the carrier bag. In some situations, only one of the handle strips 112 and 114 may need to have a handle loop 116.
  • each handle strip 112 and 114 can be of various sizes and shapes depending upon the type of carrier bag 111 to which the handle 110 is attached and the antici­pated contents of the carrier bag.
  • each handle strip 112 and 114 can be about 16 inches (35 cms) in length, one inch (2.5 cm) in height, and about a tenth of an inch (2.5 mm) in width.
  • one of the opposing handle strips has an outer closure member and the other opposing handle strip has an inner closure member.
  • the outer closure member and the inner closure member coact in a complementary snap-on engagement when the carrier bag is in a closed position.
  • One of the opposing handle strips 114 has an outer closure member 118 and the other opposing handle strip 112 has an inner closure member 120.
  • the outer closure member 118 and the inner closure member 120 coact in a complementary snap-­on engagement when the carrier bag is in a closed posi­tion, as illustrated in Figure 3.
  • the outer closure member 118 and the inner clo­sure member 120 are located on the upper portions 122 of the handle strips 112 and 114.
  • the outer closure member 118 comprises a curved wall 124 that defines a groove 126 between the curved wall 124 and the upper portion 122 of the handle strip 114 having the outer closure member 118.
  • the inner closure member 120 may be an arcuate surface 128 on the handle strip 112. The arcuate surface is of a size and shape to fit within the groove 126 when the carrier bag handle 110 is in a closed position.
  • the curved wall 124 extends along a major portion of the length of the handle strip 114.
  • the arcuate surface 128 on the handle strip 112 extends along a major portion of the length of the handle strip 112.
  • Ribs 140 as shown in Figure 3, can also be positioned within the arcuate surface 128 and enhance the snap-on engagement. This snap-on engagement of the inner closure member 118 and the outer closure member 120 is especially shown in Figures 5 and 6.
  • the arcuate surface 128 is positioned within the groove 126 of the curved wall 124 to provide a complementary snap-on engagement between the arcuate sur­face 128 and the curved wall 124 defining the groove 126.
  • the snap-on engagement is achieved by snapping the curved wall 124 over the arcuate surface 128.
  • the snap-on engagement is relieved by removing the curved wall 124 from the arcuate surface 128 by lifting up a small tab 142 in the centre of the curved wall 124.
  • each handle strip retains the handle strips together at the lower portion when the handle strips are adjacent to each other.
  • the interlocking means is formed by one or more complementary interlocking slots 130 and tabs 132 on the handle strips 112 and 114 near the bases 134 of the handle strips 112 and 114.
  • Each slot 130 is preferivelyably formed by end sections 136 extending substantially perpendicular to the handle strip 114.
  • a crossbar 138 interconnects the end sections 136 to form an opening or slot 130 on the handle strip 114, as shown in Figures 8 and 9.
  • the opposing handle strip 112 has one or more tabs 132 extending from the base 134 of the handle strip 112.
  • the tabs 132 on the handle strip correspond in number, size and orientation with the slots 130 on the handle strip 114. Consequently, the tabs 132 slide into the slots 130 when the handle strips 112 and 114 are in the closed position.
  • the tabs 132 on the handle strip 112 are aligned above the slots 130 on the handle strip 114.
  • the tabs 132 are then slid downwardly into the slots 130.
  • the curved wall 124 is snapped on to the arcuate surface 128 to form a snap-on engagement of the inner closure member 120 and outer closure member 118.
  • the carrier bag handle provides a double lock system for the carrier bag, namely the tab and slot engage­ment and the snap-on engagement.
  • the curved wall 124 is first snapped off of the arcuate surface 128 to release the snap-on engagement of the inner closure member 120 and the outer closure member 118 by lifting up the small tab 142 in the centre of the curved wall 124. Then, the handle strips 112 and 114 are moved laterally away from each other so that the tabs 132 are lifted out of the slot 130. Only then is the carrier bag fully opened.
  • the closure bag handle of the present invention is preferably used in combination with a bag made of rela­ tively thin polyethylene material.
  • a bag made of rela­ tively thin polyethylene material can also be used within the scope of the inven­tion.
  • the bag handle strips 112 and 114 are preferably attached to the carrier bag 111 along lines 144 of each handle strip 112 and 114 by various techniques known in the art, such as heat welding. It is an important feature of the invention that the interlocking means located ad­jacent the lower edges of the handle strips are applied below the line of attachment of the bag to the handle strips, i.e. on the side of the attachment line remote to the handle loop.
