Description

Sammentrykkbar tube med lukkeinnretning. Compressible tube with closure device.

Denne oppfinnelse vedrører en sammentrykkbar tube som ved sin ene ende er forsynt med en tut med en ak,sial kanal og med en lukkeinnretning. This invention relates to a compressible tube which is provided at one end with a spout with an axial channel and with a closing device.

Slike tuber er alminnelig kjent og lukkes vanligvis ved hjelp av en skruekapsel. De tidligere kjente tuber er imidlertid be-heftet med den ulempe at en viss mengde av tubens innhold blir igjen på kanten av tutåpningen etter bruken av tuben, og går gjennom mellom gjengene når kapselen senere skrues på, for å presses ut ved kapselens nedre kant, slik at tuben ikke kan holdes ren. Videre, hvis tuben skal lukkes effektivt, må kapselen skrues til temmelig tett, hvilket ofte resulterer i at tuben trykkes sammen og beskadiges eller øde-legges. Such tubes are generally known and are usually closed using a screw cap. The previously known tubes are, however, afflicted with the disadvantage that a certain amount of the tube's contents remains on the edge of the spout opening after the use of the tube, and passes through between the threads when the capsule is later screwed on, to be pushed out at the capsule's lower edge, so that the tube cannot be kept clean. Furthermore, if the tube is to be closed effectively, the capsule must be screwed quite tightly, which often results in the tube being compressed and damaged or destroyed.

Også de vanlige tube-lukkeinnretnin-ger med en beskyttelseskapsel som er Also the usual tube closure devices with a protective cap which are

skrudd over hele tuten for å holde tuben lukket lider av visse ulemper, idet kapselen fylles med tubens innhold, og når den skal skrues på neste gang, vil innholdet presses ut langs kapselens kant. screwed over the entire spout to keep the tube closed suffers from certain disadvantages, as the capsule is filled with the contents of the tube, and when it is to be screwed on next time, the contents will be pushed out along the edge of the capsule.

Siden tubene i de fleste tilfelle fylles Since the tubes are in most cases filled

under et visst trykk, vil det ofte hende at det ved første gangs bruk vil renne ut en større mengde av innholdet enn det er ønskelig, når kapselen skrues av. under a certain pressure, it will often happen that when the capsule is unscrewed, a larger amount of the contents than is desirable will flow out on first use.

Det hender ofte at man glemmer å sette kapselen på, hvilket har til følge at innholdet i tubens øverste del størkner og blokkerer åpningen. It often happens that people forget to put the capsule on, which results in the contents in the upper part of the tube solidifying and blocking the opening.

Hensikten med oppfinnelsen er å skaffe en lukkeinnretning som danner en kontinuerlig enhet med tuben og som ikke lider av de ovenfor nevnte ulemper. The purpose of the invention is to provide a closure device which forms a continuous unit with the tube and which does not suffer from the above-mentioned disadvantages.

Tuben i henhold til oppfinnelsen er sammentrykkbar og av den art som er forsynt med en tut med en aksial kanal og en åpning i tutveggen, hvor den aksiale kanal inneholder et lukkeorgan som ut-gjøres av et stempelformet element som er avpasset til å beveges med trang pasning i tuten og hvor det i elementet også er utformet en aksial kanal som er lukket i den ut fra og åpen i den inn i tuben ragende ende, i hvilken sistnevnte kanals vegg er anordnet en eller flere åpninger, og hvor i en bestemt stilling av lukkeelementet åpningen i tutens vegg kommer i korrespondanse med en åpning i lukkeelementets vegg og utmerker seg ved at formen og dimensjonene til lukkeelementets inn i tuben ragende del svarer til formen av partiet som utgjør overgangen fra tuten til tubelegemet og hvor det i nevnte parti er anordnet en eller flere åpninger over hvilke mellomrommet mellom lukkeelementets inn i tuben ragende del og overgangspartiet fra tuten til tubelegemet er forbundet med atmosfæren. The tube according to the invention is compressible and of the type which is provided with a spout with an axial channel and an opening in the spout wall, where the axial channel contains a closing member which consists of a piston-shaped element which is adapted to move with narrow fitting in the spout and where an axial channel is also formed in the element which is closed at the end from the outside and open at the end projecting into the tube, in which the wall of the latter channel is arranged with one or more openings, and where in a specific position of the closing element, the opening in the wall of the spout corresponds to an opening in the wall of the closing element and is distinguished by the fact that the shape and dimensions of the part of the closing element projecting into the tube correspond to the shape of the part which constitutes the transition from the spout to the tube body and where in said part there is arranged a or several openings over which the space between the part of the closing element projecting into the tube and the transition part from the spout to the tube body is connected to the atmosphere.

Ved en foretrukket utførelse av oppfinnelsen er lukkeelementet forsynt med en låsepinne eller -knast som samvirker med et spor som er utformet i tuten og begrenser lukkeelementets rotasjons- eller forskyvningsbevegelse. Formen av lukkeelementets innerste del svarer til formen av overgangspartiet mellom tuten og tube-legemet, slik at den nevnte lukkedel i lukket stilling vil legge seg tett an mot overgangspartiet. For å sikre at lukkeelementet legger seg tett inntil overgangspartiet kan det være anordnet åpninger som for-binder rommet mellom lukkeelementets innerste del og overgangspartiet med atmosfæren. Det kan således være utformet flere åpninger i overgangspartiet mellom tubens hode og tubelegeme. Endepartiet av en delvis tømt tube kan holdes i sam-menrullet tilstand ved hjelp av en festepinne. Tubelegemet kan være utformet av fleksibel plast, f. eks. polyetylen, mens tuten og lukkeelementet kan være av hård plast, f. eks. hård polyetylen. Oppfinnelsen skal forklares nærmere ved hjelp av et eksempel under henvisning til tegningen, hvor fig. 1 viser et vertikalt lengdesnitt gjennom en tube i henhold til oppfinnelsen og fig. 2 et tverrsnitt tatt langs linjen II—II på fig. 1. In a preferred embodiment of the invention, the closing element is provided with a locking pin or cam which cooperates with a groove formed in the spout and limits the closing element's rotational or displacement movement. The shape of the closure element's innermost part corresponds to the shape of the transition part between the spout and the tube body, so that the said closure part in the closed position will fit tightly against the transition part. To ensure that the closing element lies close to the transition part, openings can be arranged which connect the space between the innermost part of the closing element and the transition part with the atmosphere. Several openings can thus be designed in the transition part between the head of the tube and the body of the tube. The end part of a partially emptied tube can be held in a rolled-up state by means of a pin. The tube body can be made of flexible plastic, e.g. polyethylene, while the spout and the closing element can be made of hard plastic, e.g. hard polyethylene. The invention will be explained in more detail by means of an example with reference to the drawing, where fig. 1 shows a vertical longitudinal section through a tube according to the invention and fig. 2 a cross-section taken along the line II—II in fig. 1.

Til et tubelegeme 1 som ved bunnen 2 er forseglet ved bretting, folding eller sveisning er det festet en tut 3, hvis aksiale kanal 4 på et sted på periferien har en tverrgående åpning 5. I tuten er det anordnet et lukkeelement 6 som er innrettet til å kunne beveges med trang pasning og som har en aksial kanal 7 og 'en åpning 8 som ligger loddrett på kanalen 7. Lukkeelementet er forsynt med en sperreknast som samvirker med et spor 10 i tuten 3 og begrenser lukkeelementets bevegelse. Lukkeelementets innerste del 11 er av samme form som det parti 12 som utgjør overgangen fra tuten til tube-legemet og ligger med trang pasning an mot-overgangspartiet. For å lette lukkeelementets frem-og tilbakegående bevegelse kan partiet 12 være forsynt med avlastningsåpninger (13). To a tube body 1 which is sealed at the bottom 2 by folding, folding or welding, a spout 3 is attached, whose axial channel 4 has a transverse opening 5 somewhere on the periphery. A closing element 6 is arranged in the spout which is arranged to to be able to be moved with a tight fit and which has an axial channel 7 and an opening 8 which is perpendicular to the channel 7. The closing element is provided with a locking cam which cooperates with a groove 10 in the spout 3 and limits the movement of the closing element. The innermost part 11 of the closing element is of the same shape as the part 12 which forms the transition from the spout to the tube body and lies with a tight fit against the opposite transition part. To facilitate the reciprocating movement of the closing element, the part 12 can be provided with relief openings (13).

Under bruken er tuben fylt med en væske eller pasta og presses sammen i hånden samtidig som lukkeelementet presses ned med tommelfingeren eller med den annen hånd. Åpningene 5 og 8 vil da legge seg rett overfor hinannen, slik at tubens innhold vil presses ut gjennom kanalen 7 og åpningene. During use, the tube is filled with a liquid or paste and is pressed together in the hand at the same time as the closing element is pressed down with the thumb or with the other hand. The openings 5 and 8 will then lie directly opposite each other, so that the contents of the tube will be pushed out through the channel 7 and the openings.

Når tuben skal lukkes er det tilstrek-kelig å avlaste lukkeelementet. Dette vil da løftes som følge av det i tuben frem-brakte trykk, og derved lukke åpningen 5 Tubens opprullede endeparti kan holdes i denne stilling ved hjelp av en særskilt festepinne. When the tube is to be closed, it is sufficient to relieve the closing element. This will then be lifted as a result of the pressure produced in the tube, thereby closing the opening. 5 The rolled-up end part of the tube can be held in this position by means of a special fastening pin.

Tuben kan være utført av de vanligvis brukte materialer, men det foretrekkes The tube can be made of the commonly used materials, but this is preferred

et tubelegeme av ettergivende, bøyelig plast, som f. eks. polyetylen, mens tuten og lukkeelementet skal fortrinsvis være av hård plast, f. eks. hard polyetylen. Tuten og tuben kan også danne en kontinuerlig enhet. a tubular body of compliant, flexible plastic, such as e.g. polyethylene, while the spout and the closing element should preferably be made of hard plastic, e.g. hard polyethylene. The spout and tube can also form a continuous unit.
