Abstract

An envelope is disclosed herein which comprises a perforated line 1, formed parallel in proximity to the edge of an envelope 10 preferably at the shorter edge 2 intersecting the closed flap 5 from one edge 3 to the opposite edge 4. The sealed envelope can be opened by tearing along the perforated line 1 until the two parts 6 and 7 are completed separated.

Description

Ei~~'~L,OPE
~ackgroundl and ~'ierd of tl~e Inventioat This invention relates to ar_ ant,°elope with a perforated line.
~velopes are used to contain separate ar4zcles such as letters for mailing.
Envelopes are normally rectangular in shape having an ope~nin~ for inserting the article and for sealing thereafter.
r0 ~iowever when an envelope is sealed, it needs to be cut open with scissors or a letter-opener to create an openinJ for retrieving the. content. This causes irnconvenience to the recipient especially if no cutting instruzr~ent is immediately available. It is likely that the recipient will simply tear the envelope open harstzly to get the content out with. a feelinb of frustration, possibly daxnagin~; the content in the process.
Uver the years, a numoer ofiznprovements have been proposed to create ''easy-open"
envelopes particularly to make them more user friendly, improved technical desi~ and more economical. Although these improvements are able to perform the intended function, it increases the manufacturing costs of such envelopes si~ifieantly so much so that the mass public, government departments ar~.d paivate institutions recognise their usefulness but are reluctant to implement them due to its higl~i costs.
~'or example, there have been proposed envelopes which can be. opened relatively easily such as an envelope proposed in pat~t document US 6,22~,977.1"his envelope has opening features that also ser~%e as tamper eviden; indicators. However, such envelopes axe costly to manufacture and require specialised :nachineiy. Further, an patent document U~ 8,457,638, an eriVelop° :.S dISCIOSed ~ulkich requires a separate pull opener comg~rising a pair of pull-tabs and a tearing filament. This increases tine cost of the envelope since the S puL.-tab adds to the cost of producing the envelope apart from *.he heavy investanent oar the machinery.
It is an object ofthe present inventian to provide an improved envelope vrhich alleviates at least one of the above disadvantages and to provide the p~xblic with a useful choice.

Summary of Inwentio~a rn a first aspect of the invention, there a provided an envelope comprising a flap attached to an edge of the envelope movable between an open position and a sealed position in 15 which in the sealed position the flap is folded on to the remainder of the envelope, and a perforated line formed on the envelope vvhereb~l, when the flap is in the sealed position, the perforated lire runs through the remainder of the envelope.
E1n advantage of the describe d embodiment of the invention is tha~~ it alloys opening of 20 a sealed envelope in a proper and convenient manner since one's firagers can simply be used to tear along the line formed by the perforations readily °uithout the need to use a cutting instrument such as scissors or a letter opener. Further, having the perforated line running through the flap and the remainder of the envelope allows the line to be visible on bath sides of the envelope and thus a recipient is more li:~ely to how the presence of such a feature as cernpared uo other prior art envelopes in which tree pull mechanism are usually visible from one side- of the envelop.
Typically, the envelope is us~:d to contain separate articles to be mauled.
In a second aspect of the invention, there is provided a method of producing a perforated line on an envelope having a flap movable between an open and a sealed position in which in the sealed position, the flap is folded on to the remainder of the envelope, the method comprisinb the steps of; folding the flap to the sealeoi position, and lo thereafrer forming a perforated line through the clap and the remainder of the envelope.
~n a third aspect of the invention, there is provided a method of producing a perforated line on. an envelope having a flap movable between an open and a sealed position in which in the sealed position, !he flap is folded an to the rerruainder of the envelope, the method comprising the step of; forming a perforated line on the envelope, characterised in that vc~hen the flap is in the sealed position, the perforated. line runs throujh the flap and the remainder of the envelope_ Ln a fourth aspect of the invention, there is provided an envel~pe co:mprising a perforated line formed on the surface parallel in proximity to the edge of tire envelope preferably at the shorter edge characterized by said line formed over the closed f((ap of the envelop°.
The envelope as described. in the present invention. is user friendly to the recipient since no separate pull-tabs or strings are needed to open the envelope. 'a'his can be useful for 4"
government deparxrtents and private institutions such as bays and insurance companies etc. ih3t seek to p.ovide better service to the public and their customers.
brief Descripti~n of the Dra~imgs Yn order th.a. the present inv entron may be more readily understood, the follo~ng descriptions are even by way of example, of a specific emhodiment of an envelope made in accordance to the present invention. FLefererce will he made to the accompanying drawings in which:
lo Fig. l shows a front elevation view of an envelope in acGOr<iance with a preferred embodiment of the ~~resent invention.
~'ij. ? shovcrs a rear elevation view of the envelope of Fig. 1.
IS
~'zg. 3 illustrates ho~~ the envelope is being opened by tea~ino along a perforated line.
Defeated Description of tlm preferred Ernbodicnent lteferrin~ to Fig. l, it can be seen that the perforated line 1 is formed parallel in proximity to the shorter edge '? of an envelope IO from one edge 3 extending to thz opposite edge 4. It is preferred that the perforated line J, be situated riot too far from tlse said edge 2 so that tearing along the perforations can be done without being obstructed by tile content inside the envelope 10.
Fig. 2 shows ',he opposite side of tile envelope 10 shown in Fig. 1. It can be seen that the 5 perforated line 1 corresponds with the perforatEd line 1 shown in Fig. I
since the perforations are cut through lo the other side of the envelope; 10, 'The flap 5 is in a closed fashion before the perforations are s°~mped over it so that the 'nvelope 10 can be opened by tearin' along the perforated line 1 when the closed flap S is sealed. It will be agparent that a conventional. pe~foratior~ tool can be used to form the perfozate~l. line 1, since the liras I is to fornled after fozirLing the envelcspe 10 h-orxt a blank F'ig. 3 illustrates the opeuin3 of the envelope 10 in use by tearing along the perforated line 1.
This is done by gripping hold of ea.eta part ~ and 7 of the envelope 10 with the perforated line 1 in between and tearinJ progressively begiiuling froth one; end of the line until both t5 parts are completEly separated.
For mass production of the envelope 10 according to the preferred embodiment, the convention perforation tool car_ easily be adapted to an existing rnaclline at the end of the envelope making process. A.s and when, normal envelopes without the perforated line 1 are 20 needed, the perforation tool can simply be removed. Thus, this makes it very economical and cost effective no produce the env elopes 1 O of the present invention. sire no new machinery is needed and thus no upfront im~estrnent_ Furdler, tl~ae costs ofthe ~erwexopd 10 would remain competitive (possibly at tile same cost) to a conventional envelope without the perforated line 1. It vcriil thus be appreciated that the envelope 10 of the present invention achieves obj ectives ofbLinb simple to open and ai the sair:e time, reduci:~~ the manufacturing costs of produ~i~
such envelopes since there is r~o need to i!-wesl in expezisive ne":v mmacc'n:nery, unlike the prior art envelopes- It shall be understood that the perfora.~d line 1 can be applied to all sizes and types of envelopes. It is suggested that explanatory instruction be printed beside the perforated line 1 example "'To open, please tear aloa~,, perforated line."
Alternatively, a simple instruction such as ''Upen here'' is printed beside or near the perforated line 1 to draw tire recipien.t's attention to such a feature.
The described embodiment should not be constnzed as lirnitative. for example, although it 1o is preferred to form the perforated line 1 after folding the flap j, it is also envisaged that with the flap 5 extended, a perforated line is formed sepatateLy on the flap 5 and the envelope 10 such that when the flap .~ is folded, both perforated lines are aligned and thus still vans all the way through the envelope I0.
It wi.Il ofcourse be realised that ~.vhilst the above has been gzven by way of a preferred exarnpie of the invention, all such otl-~~er modifications and variations thereto as would be apparent to the persons skilled in the art, are deemed to fall within. the faroad scope of the Javention as claimed.
